  1. 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)

    Qualitative and quantitative analysis of Thanetian foraminiferal assemblages at Gebel Matulla in west-central Sinai has been carried out. Three benthic foraminiferal assemblages are recorded from shallowest to deepest as Cibicidoides pseudoacutus, Angulogavelinella avnimelechi, Gavelinella danica witch evidences of fluctuations from middle neritic to upper bathyal environments. Changes in the foraminiferal population enabled us to classify the Thanetian succession into two fourth order transgressive-regressive (T-R) sequences. Three sequence boundaries are identified, at the Selandian/Thanetian (S/T) boundary, within the Thanetian succession, and the Paleocene/Eocene (P/E) boundary. It occurs at the top part of the maximum regression associated with major discontinuities and changes in depositional regimes as well as vertical facies changes. Broad correlation with eustatic records based upon integrated microplanktonic biostratigraphy suggests that the fluctuations of foraminiferal population were controlled by global sea-level changes.

    The Oligo-Miocene Gulf of Suez rift is characterized by four fault trends; a rift-parallel trend, two trends oblique to the rift trend and a cross trend. The rift-parallel trend strikes 310o to 340o and is referred to as the Clysmic trend. The two trends, which are oblique to the Clysmic trend, strike 350o to 030o and 280o to 310o; the first has been referred to as the north-oblique (N-oblique), and the second as the northwest-oblique (NW-oblique). The cross trend includes faults nearly orthogonal to the Clysmic trend i.e. they strike between 050o and 075o. Image interpretation and detailed field mapping and structural studies at a scale of 1: 20,000 of the Wadi Araba area in southwest Sinai Peninsula indicate e Clysmic faults are mostly normal showing major dip-slip movements. The oblique faults were found to be younger than the Clysmic faults and that the N-oblique faults are characterized by major sinistral strike-slip movement, while the NW-oblique faults are characterized by major dextral strike-slip movement. Cross cutting relationship, geometry and palaeostress analysis indicate that the oblique faults are conjugate Riedel shears originated due to NE to NNE extension related to the Aqaba-Levant transform that has been active since the Middle Miocene.

  4. 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

    The Lower Palæozoic Naqus Formation of Gebel Gunna in the Sinai Peninsula is conformably underlain by the Araba Formation and unconformably overlain by the Cenomanian Malha Formation. It consists mainly of fine- to medium-grained pebbly sandstones with a few siltstone and granulestone interbeds. Petrographical, X-ray diffraction, scanning electron microscope and chemical analyses of the sandstones revealed that they are mainly quartzarenite, containing allogenic and authigenic clays. The allogenic clays were found in small amounts. Such clays exhibit some of the characteristic features of infiltration clay coats. The clays coat a few grain surfaces and form meniscus-shaped pore bridges at points of grain contact. In addition, the clays were observed on the surfaces of crystalline authigenic minerals and in-filled elongated pores of partially dissolved feldspar grains. The recorded authigenic clays are mainly kaolinite with a minor amount of illite. The kaolinite exhibits three morphological habits: vermicular, blocky and fan-shaped. The vermicular kaolinite is dominant and was interpreted to have formed by dissolution of feldspar grains. The blocky kaolinite was observed with a textural relationship, indicating that it was neomorphosed after vermicular kaolinite. The fan-shaped kaolinite was found to be a result of mica alteration. Study of both allogenic and authigenic clays has helped in understanding the sedimentological history of the studied sandstones. The sandstones were deposited in a braided stream, buried at depth of about 1-3 km, and afterwards subjected to surface exposure.

    In the Middle East, the fat sand rat Psammomys obesus is the most important reservoir host of zoonotic cutaneous leishmamiasis (ZCL). It is the most incriminated host in outbreaks. Two P. obesus caught in Wadi El Gedeiret (Al Arish, North Sinai) were found naturally infected with Leishmania major as indicated by enzyme electrophoresis. In Egypt, the already known reservoir hosts are Gerbillus pyramidum I. Geoffroy St. Hilaire, 1825; Meriones crassus Sundevall, 1984 and Meriones sacramenti Thomas, 1922. The hostal role of P. obesus was discussed.

    The objective of this work was to study gastrointestinal nematode community infecting Acomys dimidiatus in different wadis of St. Katherine, South Sinai, Egypt. Fieldwork was conducted in three Wadis over a 4 weeks period during April-May, 2003 in St. Katherine, South Sinai, Egypt. Faecal samples from 47 spiny mice were analysed for gastrointestinal nematode community. The nematodes community consisted of four genera Dentostomella spp., Syphacia spp., Aspicularis spp. and Spirurids species. The overall prevalence of infection was 55.3 %. A significant difference in prevalence was found per wadis. Wadi Toffaha showed the highest diversity when compared to other Wadis. Mean species richness was higher in Wadi Tlah (0.87) when compared to other Wadis. Syphacia spp. was frequently found coexisting with other nematodes. A significant interaction was found between both site and co-infection for Aspicularis spp. The spatial stability of nematode community was discussed compared to other related studies. In terms of similarity, the nematode community from Wadi Toffaha was closest to Wadi Tlah. In conclusion, this study showed that there is spatial variation in the distribution of nematode community. Possible factors affecting the stability of parasite community were discussed and further studies are needed. PMID:26688638

    The sulfate-reducing bacteria within the surface layer of the hypersaline cyanobacterial mat of Solar Lake (Sinai, Egypt) were investigated with combined microbiological, molecular, and biogeochemical approaches. The diurnally oxic surface layer contained between 10(6) and 10(7) cultivable sulfate-reducing......, and aggregate formation were the most conspicuous adaptations of Solar Lake sulfate-reducing bacteria to the mat matrix and to diurnal oxygen stress. A comparison of sulfate reduction rates within the mat and previously published photosynthesis rates showed that CO2 from sulfate reduction in the upper 5 mm...... bacteria ml(-1) and showed sulfate reduction rates between 1,000 and 2,200 nmol ml-l day(-1), both in the same range as and sometimes higher than those in anaerobic deeper mat layers. In the oxic surface layer and in the mat layers below, filamentous sulfate-reducing Desulfonema bacteria were found...

    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.

    Although Leishmania major is endemic in parts of the Sinai of Egypt, the ecology and distribution of Leishmania sand fly vectors in southern Sinai has not been well characterized. Accordingly, additional sand fly samples were obtained at 41 sites in the southern Sinai region during 1996-1997, and analyzed to improve the characterization of risk of sand fly-borne pathogens. Using a Geographic Information System (GIS), species-specific spatial distributions that might suggest zoonotic cutaneous leishmaniasis (ZCL) risk areas were determined in relation to contextual environmental factors, including geology, hydrogeology, climate variables and elevation. Southern Sinai was characterized by a diverse sand fly fauna (eight Phlebotomus species), probably attributable to highly variable landscape and environmental factors. Phlebotomus alexandri, Phlebotomus kazeruni and Phlebotomus sergenti were widespread and abundant, Phlebotomus papatasi and Phlebotomus bergeroti were less frequent, and Phlebotomus arabicus, Phlebotomus major and Phlebotomus orientalis had highly restricted distributions. Logistic regression models indicated that elevation and climatic conditions were limiting determinants for the distributions of sand flies in southern Sinai. Based on the predicted distribution of P. papatasi, a recognized vector of L. major, about one-quarter of southern Sinai may be at high risk of ZCL. Risk areas for the suspected ZCL vector P. bergeroti had a more patchy distribution. Results suggest that future studies should include other factors related to vector abundance, vector competence, human population, and parasite and reservoir host(s) to produce more comprehensive ZCL transmission risk maps, thus helping in planning effective prevention and control strategies.

    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

  17. 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.

  20. Rapid Measurement of Radon Daughters Concentrations in Allouga Uranium Exploration Gallery, 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

    Aquifers in Egypt (e.g., Nubian Sandstone, shallow alluvial) were primarily recharged in previous wet climatic periods in the Quaternary. Previous studies have shown that both aquifers are receiving modern recharge under the current drier climatic conditions. The validity of these advocated models was tested using geophysical (conventional Electrical Resistivity, [ER]) and isotopic (O, H) data, and estimates for modern recharge were obtained using continuous rainfall-runoff modeling over the period 1998-2007. First-order estimates of the average annual modern recharge for the NSS aquifer (~13.0 x 10^6m^3/yr) and the shallow Alluvial aquifers in the Sinai Peninsula for the investigated watersheds (456 x 10^6m^3/yr) and the shallow Alluvial aquifers in the Eastern Desert (147 x 10^6m^3/yr) were computed using the SWAT (Soil Water Assessment Tool) model and readily available global remote sensing data sets (e.g., TRMM). Projections of climate change over North Africa from three of the leading general circulation models (GCMs) (GISS, GFDL, and UKMO) indicate a potentially high degree of vulnerability in the future precipitation amounts in Egypt. For each of the major watersheds and the Nubian Sandstone outcrops, we ran the calibrated model over the investigation period (1998-2007) using the obtained average annual precipitation and additional values of 10, 50, 100, and 150 mm. The SWAT model outputs were then used to extract relationships describing variations in runoff, recharge, and evaporation in relation to average annual precipitation amounts. Using developed tools on a web-based GIS interface we described these relationships under various climatic trends. Using a 10% decrease in rainfall in Egypt results in decreasing the average annual recharge to the shallow Alluvial aquifers in the Sinai Peninsula (384 x 10^6m^3/yr) and in the Eastern Desert (111 x 10^6m^3/yr). The observed differences between the watersheds in the partitioning of precipitation and in their

    The Paleozoic sandstone succession between Wadi Feiran and El-Tor in southwestern Sinai has been subdivided into five distinct lithostratigraphic units: the Lower Cambrian Araba Formation; the Upper Cambrian Naqus Formation; the Lower Carboniferous Abu Durba Formation; the Upper Carboniferous Aheimer Formation and the Permian Qiseib Formation. The present study has also proved that the Paleozoic Earth movements have undergone distinct changes in the sedimentary facies, together with lateral variations in the composition and thickness of strata. The distribution of the sediments and their faunal contents point to the existence of five major phases of sedimentation during the Paleozoic Era.

  6. 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

    A thick succession of Cambrian sediments is exposed in the Taba region, east Sinai, and subdivided into the Araba Formation and the overlying Naqus Formation. The vertical and lateral distribution of the Araba Formation in the Taba region provides an outstanding example of an overall retrograding sequence. Three distinctive units (I, II and III) are distinguished within this succession on the basis of depositional geometries, stratified patterns, sedimentary features and petrographic examinations. They record different depositional environments and each unit is distinguished by a particular facies association, which records processes characteristic of these environments. The lower unit (I) is dominated by five depositional facies (la-le) which belong to low sinuosity braided channels associated with floodplain fines and alluvial fans. Channel deposits are represented by tabular cross-bedded and horizontally stratified pebbly coarse-grained sandstones. The middle unit (II) reveals a relative sea level rise and is composed of fine- to coarse-grained sandstone, shale and mudstone with carbonate intercalcations. From four depositional facies (Ila-Ild), recognised facies (Ila, Ilc and Ild) are comparable to upper-lower shoreface and tidal channel environments. The fourth facies (Ilb) is carbonate-dominated with trilobite tracks, and reflects deposition in the upper-middle intertidal flat. The latter facies (llb) is subjected to intea-Cambrian karstification, which is deduced from the presence of macro- and microscopic fresh water calcite fillings, botryoidal Fe and Mn oxides and terra rossa. The uppermost unit (III) is shale-dominated from the inner shelf and is represented by two facies (Illa and Illb). Despite the general rise in sea-level in the Araba Formation, the uppermost facies (Illb) points to a progradational-upward tendency in unit (III), and this is coeval with an increase in the percentage of interbedded fine-grained sandstones.

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

    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.

  9. Rn-Gas Concentration and Working Level Measurements Using SSNTD in Uranium Exploration Galleries Allouga Mine, Sinai, Egypt

    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

    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.

    Sandstones of the marine Lower Cambrian Araba Formation and the overlying fluvial Upper Cambrian( ) Naqus Formation in Gebel Araba-Qabeliat, southwest Sinai (the eastern side of the Gulf of Suez) were studied to evaluate the major factors controlling potential hydrocarbon reservoir quality. The formations have a composite thickness of 873 m and overlie Precambrian granite and metamorphic rocks and underlie Cretaceous marine strata. The framework composition of both sandstones is almost entirely quartz with trace amounts of muscovite, K-feldspar, and heavy minerals. Up to 21.5% oversize pores, some filled with younger cements, attest to extensive dissolution loss of detrital grains, chiefly feldspar. Because the final mineralogical maturation of these quartzarenites was through diagenesis, they are diagenetic quartzarenites. Following deposition, the introduction of thin coatings of infiltered clay was followed by the precipitation of 6.3% unhomogeneously distributed quartz cement. Some outcrop samples contain pore-occluding gypsum cement or mixtures of gypsum and halite cement. Sr{sup 87}/Sr{sup 86} ratios of seven samples of gypsum cement have values (0.7077 to 0.7083) that are equal to Miocene and slightly younger seawater. These Cambrian sandstones have excellent reservoir potential (mean thin section porosity = 25.7%) because they contained few ductile grains to enhance compaction, and they developed significant amounts of secondary pores by both dissolution of calcite cement and unstable detrital grains. Kaolinite and dickite are potential problems for hydrocarbon production in some beds.

    El Qaa plain is one of the areas that have been proved to be promising as to its soil and groundwater resources in the southwestern part of Sinai. This study was carried out to study the lateral and vertical variations in the subsurface lithologic properties in El Qaa plain area and delineating the subsurface structure that affecting El Qaa plain depression. Gravity, magnetic data, fifty-one (51) vertical electrical sounding (Ves's) and Digital Elevation Model (DEM) map were used. Two-dimensional density modeling, analytical signal, tilt derivatives, Euler deconvolution techniques and interpretation of the resistivity data were applied on potential data. This study concluded that, El Qaa plain is a NE-SW depression confined by two normal faults and subdivided into five sedimentary units. Rock fragments and boulders derived to the plain from the surrounding highlands are the main components of the first surface unit that characterized by high resistivity values. This layer is overly another unit composed of gravelly sand with thickness ranging between 10 and 140 m. The third unit is composed mainly of sand with intercalations of clay with thickness ranging from 2 to 152 m. A Reefal limestone unit is a fourth unit interpreted from this study. The fifth unit is composed of clay. The water bearing formations in El Qaa Plain area are located principally in the second and the third layers. Finally, the depth to the basement surface ranges from 400 m to more than 1.5 km below sea level. Also, there are many minor structural trends interpreted from this study and affecting the El Qaa plain are striking in N-S, E-W and NE-SW directions.

    The Gulf of Suez region represents the most promising area in Egypt for geothermal exploration which is characterized by superficial thermal manifestations represented by a cluster of hot springs with varying temperatures from 35 to 72 °C. The main purpose of the present study was to shed the light on the integration between gravity work and geothermal data in detecting the main subsurface structures in addition to expecting the geothermal sources in the area under consideration. Correction was applied on the bottom hole temperature data to obtain the true formation equilibrium temperatures that can provide useful information about the subsurface thermal regime. Based on these logging data, temperature gradient and heat flow values were computed at each well, and it is found that the mean geothermal gradient of the study area is 32 °C/km; nevertheless, some local geothermal potential fields were located with more than 40 °C/km. Also, heat flow values are ranging from 45 to 115 mW/m2. The Bouguer anomaly map of the study area was used for delineating the subsurface structures and tectonic trends that have resulted in a potential heat source. The gravity inversion revealed a good correlation between areas of high temperature gradients, high heat flow and positive gravity anomalies. The high temperature gradient and heat flow values suggested being associated with a noticeable hydrothermal source of heat anomaly located at relatively shallow depths which is expected to be due to the uplift of the basement in the area.

    The concentrations and distributions of naturally occurring radioactive materials were studied with the aim of detecting and mapping radioactive anomalies as well as monitoring the environment for black-sand beach deposits in Northern Sinai, Egypt. For this purpose, ground gamma-ray spectrometric surveys were conducted using a portable GS-512 spectrometer, with an NaI (Tl) detector, on an area 77.5 km(2) in surface area located between the cities of Rafah and Elareish on the Mediterranean Sea coast. The results revealed that the black-sand beach deposits could be differentiated according to their total-count (TC) radioactivity into five normally distributed interpreted radiometric lithologic (IRL) units denoted by U1, U2, U3, U4 and U5. The computed characteristic TC radiometric statistics of these five IRL units range from 4.67  to 9.96 Ur for their individual arithmetic means. The computed arithmetic means for the three radioelements K, eU and eTh reach 0.46 %, 2.25 and 6.17 ppm, respectively for the whole study area. Monitoring the environmental effects of radioelement concentrations on the study area showed that the mean natural equivalent radiation dose rate from the terrestrial gamma-radiation of the whole area attains 0.33 mSv y(-1). This average value remains on the safe side and within the maximum permissible safe radiation dose (radioactive dose generated mainly by monazite and zircon minerals, two of the main constituents of black sands.

    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.

  18. 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

  20. Aqaba-Levant transform-related faults in the Gulf of Suez rift: The Durba-Araba fault, Sinai Peninsula, Egypt

    2014-09-01

    The Gulf of Suez rift is dominated by NNW- to NW-striking “Clysmic” faults trending parallel to the rift. In addition there are NNE- and WNW-striking (oblique) faults that trend at an angle to the rift. The Durba-Araba fault (DAF) in southwestern Sinai represents one of several NNE-striking faults. It separates the Durba fault block on its NW from the Araba fault block on its SE. Detailed (1:20,000 scale) field mapping and structural studies of the DAF and the onshore area to the east of Belayim Bay (eastern margin of the central Gulf of Suez rift), indicate that the exposed part of the DAF extends for 7.5 km NNE from the mouth of Wadi Araba, at which point it bends and splays into three N- to NNW striking faults, forming a horse tail structure. The fault shows 4 km of pure sinistral strike-slip displacement. Northerly plunging fault propagation folds in the Phanerozoic rocks adjacent to the DAF accommodated the sinistral displacement. These folds are cut and displaced by the splay faults. Near its northern end, the middle splay fault affects the Pliocene El Qa'a Formation. At Gebel Qabeliat a group of en echelon left-stepping NNE- to N-striking faults overlaps the DAF generating a pull-apart (rhomb) graben, in which Pliocene and Quaternary sediments are downthrown against the Upper Miocene rocks. Kinematic indicators on most of these faults show major sinistral strike-slip movement. Palaeostress analysis of slip striae indicates sub-horizontal ENE to NNE extension, comparable to the present day stress regime. Cross-cutting relationships indicate that the NNE- to N-striking oblique faults are younger than the NW-striking Clysmic faults. These faults are probably presently active since they affect Pliocene and Quaternary sediments. It is proposed that these faults are related to the Aqaba-Levant transform that has been active since the Middle Miocene.

    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.

    There is very little dated evidence on wet periods in the Eastern Desert and Sinai Peninsula of Egypt during the Late Pleistocene and Holocene. To obtain such information, we have studied the petrography, isotope geochemistry and AMS radiocarbon ages of mostly relict tufas deposited by springs draining perched ground water bodies in metamorphic and volcanic rocks. The tufas unconformably overly Precambrian basic igneous rocks (basalt, diabase and gabbro). As the ages of tufa carbonate are frequently older than the true ages of the deposits because of the incorporation of old, 14C-dead carbon, we have dated both the carbonate matrix and insoluble organic material of the tufas. These ages show that the tufas were largely formed during two broad time periods, the most recent from 12,058 to 6678 cal yr BP (African Humid Period), and the other from ˜31,200-22,500 cal yr BP, with preferential growth during the coldest times of this period namely during Heinrich Events 2 and 3 (H2 and H3) and the Last Glacial Maximum (LGM). The time span between 19,000-9000 cal yr BP, including the YD and H1, appears to have been relatively more arid than the earlier LGM or H2 periods or the later Holocene. The Late Pleistocene tufas are depleted in 18O relative to the Holocene tufas and were deposited at a lower temperature (˜14.0°-20.8 °C vs. 18.4°-23.4 °C). We believe that the Holocene tufas in the Sinai were formed by rainfall from the Mediterranean and those in the southern part of the Eastern Desert by African monsoon rainfall derived from the Red Sea-Gulf of Aden and Indian Ocean. In contrast, the moisture that fed the Late Pleistocene tufas, which are depleted in 18O relative to Holocene deposits, and progressively depleted from north to south, was probably brought by the Westerlies from the Atlantic-Mediterranean Sea when the Westerly circulation was pushed southwards during the coldest periods of the Late Pleistocene. Periods of tufa deposition correlate with major

    Full Text Available Human activities on coasts and climate changes during the past ten years have given rise to considerable shoreline changes along the El Arish coast (the northern coast of the Sinai Peninsula. In the El Arish Power Plant, sediment accretion has reached the tip of the breakwaterof the cooling water intake basin, necessitating extensive dredging inside the basin. To the east of El Arish Harbour, the shoreline has been incontinuous retreat. The differences between the year 2000 and 2010 in the shoreline along the El Arish coast weredetermined by analysing satellite images from NOAA-AVHRR images. The analyses revealed erosion and accretionpatterns along the coast. The physical parameters showed that the minimum water temperature of 18°C wasrecorded at site I in winter and that the maximum was 40°C at site II in summer. The latter temperature can be attributed to the effluent dischargeof cooling water from the El Arish power plant. Spatial and temporal patterns in the distribution and abundance of macroalgae were measured at four sites(I, II, III and IV along the El Arish coast. The percentage cover of the successional macroalgae exhibited environmental fluctuations. After ten years,the phytocommunity showed that red and green algae were dominant at the study sites. Significant differences between past and current flora were observed.39 taxa recorded in 2000 were absent in 2010, while 9 taxa not previously reported were present in 2010. These changes are discussed in the context ofpossible global warming effects.PERMANOVA showed significant changes (p < 0.001 between sites, seasons, species abundance and macroalgal groups along the El Arish coast in 2000 and2010. The similarity matrix showed a significant difference between the flora in 2010 and that recorded in 2000, indicating poor similarity and changes inspecies composition among the seasons at the different sites. Most of the algae belonged to the filamentous, coarsely branched and sheet

    An integrated approach utilizing Very Low Frequency (VLF) and magnetic field surveying and temporal remote sensing data including: (1) Advanced Space Borne Thermal Emission and Reflection (ASTER) data, (2) European Remote Sensing (ERS-1 and ERS-2) radar imagery, and (3) Tropical Rainfall Measuring Mission (TRMM) was used to delineate water-bearing sub-vertical shear zones within the basement complex of the Sinai Peninsula. The following steps were undertaken: (1) the shear zones and dyke swarms within the basement complex were delineated using false color ASTER band and band ratio images; (2) the spatial and temporal precipitation events over the basement complex were then identified from TRMM data, and (3) finally, observations extracted from temporal radar and thermal ASTER bands were used to identify the water-bearing shear zones and dyke swarms. A fracture or dyke was deemed to be water bearing if: (1) it witnessed a large increase in its reflectivity and emissivity compared to its surroundings following a precipitation event, and maintained such differences for periods ranging from days to months. Field observations and VLF investigations were then applied to test the validity of our satellite-based methodologies for locating targeted aquifer types and for refining the satellite-based selections. The VLF detects conductive water-saturated subvertical breccia zones in bedrock. Thirty two VLF transects were collected in September of 2011 and July of 2012 along with 10 magnetic profiles at the same VLF locations. Both VLF and magnetic transects were acquired along a traverse perpendicular to the dike orientations with station separations ranging from 10 to 25 m. The VLF receiver (T-VLF) measures the distortion of the normally horizontal electromagnetic flux lines by local electrical conductors. At each VLF station, and for each frequency used, the following were measured: the tilt of the electromagnetic field, from the horizontal (given in percentage), the

    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.

  9. 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 150 km{sup 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 {sup 238}U, {sup 232}Th and {sup 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{sup -1} has been observed to be from 9.5 to 183675.7 BqKg{sup -1} for {sup 238}U, between 6.1 and 94,314.2 BqKg{sup -1} for {sup 232}Th and from 0 to 7894.6 BqKg{sup -1} for {sup 40}K. Radium equivalent activities (Ra{sub eq}), dose rate (D{sub R}) and external hazard (H{sub 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.

    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.

  12. Microfacies analysis of foraminifera rich sedimentary rocks from the Desert Plateau, central Egypt.

    Microfacies analysis on some samples from the Thebes Group have been carried on by means of thin sections. The study area is included in the Libyan Desert Plateau (central Egypt) at following coordinates N27° 36'30.58" E29° 44'58.34", near the biggest dune of Egypt, the Ghard Abu Muharik. Because of the round shape of the rocks and the desert patina on the surface they could easily be classified as the so called "Melonstones", which are located more southwards and mainly composed by stromatolites. On the contrary, the investigated samples show a completely different fauna and therefore have been separated from the "Melonstones". Even if shape and size are very similar and the desert patina covers all surfaces the same way the differences are impressive. To investigate the samples, two thin-sections have been prepared and analyzed at the microscope. The observed fauna is composed by: agglutinated benthic foraminifera (e.g., Dictyoconus egypticus), complex larger miliolids (e.g., Pseudolacazina cf. danatae, Fabularia sp.), alveolinids (Alveolina vredenburgi), green algae (Dasycladaceae), echinoids and corals. Because of the presence of symbionts bearing larger benthic foraminifera, which need light to feed photosymbionts, the rock was formed in a shallow water environment. With the abundant rock-building benthic foraminifera and calcareous algae the limestone shows a tendency to the packstone/wackestone facies. Based on the presence of Alveolina vredenburgi, the age of the samples can be estimate as lowermost Eocene belonging to the shallow benthic zone 5 (sensu Serra-Kiel et al., 1998). According the obtained data on stratigraphy and palaeoecology, a partial palaeoenvironmental reconstruction is possible for the Libyan Desert Plateau where outcrops are largely missing. Because of the round shape of the samples and the patina which covers them all around it can be assumed that they have been transported from longer distance. According to the geological map of the

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

    Directory of Open Access Journals (Sweden)

    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.

  14. 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

    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 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 to those of (1) OIB suites, (2) subduction-related magmatic suites, and (3) carbonatite-metasomatized peridotites. In addition, compositions characterized by (Y

    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

  17. 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.

  18. Integration of geophysical and geological data for delimitation of mineralized zones in Um Naggat area, Central Eastern Desert, Egypt

    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

  19. Solar Energy for Rural Egypt

    Science.gov (United States)

    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.

    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.

    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

    1998-12-01

    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.

    Major breaks in sedimentation, accompanied by well-developed paleosols, have been successfully used to subdivide the 600 m (1968 ft) of Paleozoic sandstone and shale sequence of southwestern Sinai, Egypt, into five smaller facies association units (i.e., formations). The lowest unit (the Araba Formation) is dominated by 1 to 10 m (3 to 32 ft) thick coarsening-up sequences of parallel-bedded, varicolored, fine-grained arkosic sandstone and muddy sandstone. This is the deposit of a low-energy prograding sandy coastal plain complex that grades upward into a thin, fining-up channel-overbank deposits with poorly developed paleosols. The overlying Naqus Formation scours deep into the Araba, and is characterized by lenticular, coarse to medium-grained, cross-bedded quartz sandstone with only a few clayey intervals. Cross-beds are common. The Naqus is interpreted as alluvial fanbraided stream deposits. A 15 to 20 m (40 to 66 ft) thick, conspicuous dark brown, ferruginous shale, ochre-yellow dolomitic sandstone and fossiliferous gray siltstone sequence, persistent all along the Qabeliat valley, overlies the Naqus and represents lagoonal deposits laterally equivalent to the shallow marine shale-dolomite sequence of the Um Bogma Formation farther north. Basal fluvial channel sands of the succeeding Ataqa Formation cut into the Um Bogma paleosol, and grade upward into the fossiliferous green-red marine shales and subordinate sandstones in shoaling-upward sequences. Southward in the Qabeliat valley, a parallel-bedded sequence of thick green shales and thin brown sandstones, both nonfossiliferous, intervenes in the middle of the Budra Formation and represents ephemeral lake deposits related to the fluvial system.

    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).

    This thesis involves development of an interactive GIS (Geographic Information System) based application, which gives information about the ancient history of Egypt. The astonishing architecture, the strange burial rituals and their civilization were some of the intriguing questions that motivated me towards developing this application. The application is a historical timeline starting from 3100 BC, leading up to 664 BC, focusing on the evolution of the Egyptian dynasties. The tool holds information regarding some of the famous monuments which were constructed during that era and also about the civilizations that co-existed. It also provides details about the religions followed by their kings. It also includes the languages spoken during those periods. The tool is developed using JAVA, a programing language and MOJO (Map Objects Java Objects) a product of ESRI (Environmental Science Research Institute) to create map objects, to provide geographic information. JAVA Swing is used for designing the user interface. HTML (Hyper Text Markup Language) pages are created to provide the user with more information related to the historic period. CSS (Cascade Style Sheets) and JAVA Scripts are used with HTML5 to achieve creative display of content. The tool is kept simple and easy for the user to interact with. The tool also includes pictures and videos for the user to get a feel of the historic period. The application is built to motivate people to know more about one of the prominent and ancient civilization of the Mediterranean world.

    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.

  13. 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.

    It is shown that instability of stringy matter near the event horizon of a black hole (the spreading effect) can be characterized by the Lyapunov exponents. For a homogeneous and isotropic horizon the (average) Lyapunov exponent coincides with the Kolmogorov-Sinai entropy of stringy matter. Due to identity of phase space volume of the string with the area of the horizon the relation between the Kolmogorov-Sinai and Bekenstein-Hawking entropies is established. The Kolmogorov-Sinai entropy measures the rate at which information about the string state is lost as the string spreads over the horizon.

    2011-07-01

    The Kolmogorov-Sinai (KS) entropy is a central measure of complexity and chaos. Its calculation for many-body systems is an interesting and important challenge. In this paper, the evaluation is formulated by considering N-dimensional symplectic maps and deriving a transfer matrix formalism for the stability problem. This approach makes explicit a duality relation that is exactly analogous to one found in a generalized Anderson tight-binding model and leads to a formally exact expression for the finite-time KS entropy. Within this formalism there is a hierarchy of approximations, the final one being a diagonal approximation that only makes use of instantaneous Hessians of the potential to find the KS entropy. By way of a nontrivial illustration, the KS entropy of N identically coupled kicked rotors (standard maps) is investigated. The validity of the various approximations with kicking strength, particle number, and time are elucidated. An analytic formula for the KS entropy within the diagonal approximation is derived and its range of validity is also explored.

    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.

Leishmania (-)-like flagellates were identified in 15 P. papatasi individuals (0.5% of 3,008 dissected females). Rodent populations were sampled in the same districts where sandflies were collected and eight species were identified: Rattus norvegicus (n = 39), Rattus rattus frugivorous (n = 13), Rattus rattus alexandrinus (n = 4), Gerbillus pyramidum floweri (n = 38), Gerbillus andersoni (n = 28), Mus musculus (n = 5), Meriones sacramenti (n = 22) and Meriones crassus (n = 10). Thirty-two rodents were found to be positive for Leishmania infection (20.12% of 159 examined rodents). Only Leishmania major was isolated and identified in 100% of the parasite samples. The diversity of both the vector and rodent populations was examined using diversity indices and clustering approaches. PMID:24821060

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

    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....

    Brucellosis is a highly contagious zoonosis that affects the public health and economic performance of endemic as well as non-endemic countries. In developing nations, brucellosis is often a very common but neglected disease. The purpose of this review is to provide insight about brucellosis in animal populations in Egypt and help to understand the situation from 1986 to 2013. A total of 67 national and international scientific publications on serological investigations, isolation, and biotyping studies from 1986 to 2013 were reviewed to verify the current status of brucellosis in animal populations in Egypt. Serological investigations within the national surveillance program give indirect proof for the presence of brucellosis in cattle, buffaloes, sheep, goats, and camels in Egypt. Serologic testing for brucellosis is a well-established procedure in Egypt, but most of the corresponding studies do not follow the scientific standards. B. melitensis biovar (bv) 3, B. abortus bv 1, and B. suis bv 1 have been isolated from farm animals and Nile catfish. Brucellosis is prevalent nationwide in many farm animal species. There is an obvious discrepancy between official seroprevalence data and data from scientific publications. The need for a nationwide survey to genotype circulating Brucellae is obvious. The epidemiologic situation of brucellosis in Egypt is unresolved and needs clarification.

  9. Structural Controls on Groundwater Flow in Basement Terrains: Geophysical, Remote Sensing, and Field Investigations in Sinai

    KAUST Repository

    Mohamed, Lamees

    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.)

  13. 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

    Lean Six Sigma, in various forms, has been used widely in many Fortune 500 companies. Motorola, General Electric, Sony, American Express, and Bechtel all use Six Sigma to improve quality and performance. While the impact of this methodology has been documented extensively by the press in manufacturing and transactional settings, less evidence is available regarding its utility in health care environments. Mount Sinai Medical Center initiated a Six Sigma program in 2000 to determine its applicability and value in a large academic medical center. This article discusses Mount Sinai Medical Center's experience adapting this methodology to improve both patient care and business processes and outcomes. We present an overview of Six Sigma, and offer examples of projects undertaken using this data-driven approach to performance improvement. Lastly, the article provides insights and lessons learned regarding this organization-wide experience.

    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.

  19. 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

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.

    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

    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{sup −14} cm{sup 2}/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.

    2010-09-01

    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

  10. 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.

    Ruban, Dmitry A.; Zorina, Svetlana O.

    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.

  12. Egypt/FOF reorganize.

    Science.gov (United States)

    1984-01-01

    In Egypt, both the national family planning program and the privately operated social marketing program, Family of the Future (FOF), are currently being reorganized. The Population and Family Planning Board, orginally charged with the responsibility of overseeing the national family planning program, was replaced by the newly created National Council. The reasons for the change and the type of program changes which will ensue from this organizational change are unclear. The FOF recently adopted a new management organizational structure, implemented a computerized management and information system, and initiated a staff training program. The management of the program's product line is now divided into 3 sections. There are separate sections for IUDs, barrier methods, and hormonal methods. Each section is responsible for developing a marketing plan for its products and overseeing the distribution of its products. The management staff is now provided with management skills training. To date, 9 managers have received training in management techniques in the US at George Washington University. Personal computers are being installed at the FOF office in Cairo. The system will be used to keep tract of inventory, volunteer activities, and product distribution and to handle accounting procedures. These innovations are expected to facilitate the handling of planned changes in FOF's product line. FOF will begin selling surgical gloves, as a supplemental item for its currently marketed IUD kit, and pregnancy testing kits for use by physicians and hospitals. Other anticipated introductions include Depo Provera, an injectable contraceptive, the new Ortho vaginal tablet which will replace the currently marketed Annan vaginal tablet, and possibly, the implant contraceptive, Norplant. Triton is currently under contract with the US Agency for International Development to provide technical assistance for the FOF program. This contract is due to expire in December, 1984, and a

  13. 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)

  14. 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.

  16. Environmental natural radioactive and radiation hazard in sedimentary rocks for manganese-iron ore at Um Bogma Area, Sinai, Egypt

    International Nuclear Information System (INIS)

    The aim of this study was to measure concentrations and distributions of natural radionuclides occurring in sedimentary rocks. The activity concentrations of the naturally occurring radionuclides 238 U,232Th,and 40K in the manganese-iron ore of Um Bogma area which subdivided into three localities Wadi Nasieb (NS), Abu Thor (AT) and Um Bogma (UB) were measured using a high-purity germanium detector.The average concentration values of 238U,232Th, and 40K in the surveyed samples in Wadi Nasieb are 261.38, 9.57 and 130.63 Bqkg-1 respectively also in Abu Thor 224.51,6.7,94.99 Bqkg-1 and in Um Bogma 441.47,7.87 and 272.69 Bqkg-1. The overall outdoor terrestrial gamma dose rates fluctuate from 103.38 to 193.5 nGyh-1 for all localities. The annual effective dose rate for all localities ranged from 0.13 to 0.24 mSvy-1 have been compared with the global averages which are within the safety range for workers in the studied localities.

  17. 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

    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.

    The concentrations and distributions of the activity of natural radionuclides in soil samples were investigated in fifteen soil samples at El-Gor area representing two profiles (A and B) using a HP-Ge detector and alpha counting by SSNTD (CR-39), respectively. The average concentrations of the radionuclides (238)U, (226)Ra, (235)U, (232)Th and (40)K are 203.4, 177.23, 9.77, 43.33 and 386.22 Bq kg(-1) (dry weight), respectively, and profile A and (238)U, (226)Ra, (235)U, (232)Th and (40)K have average concentrations of 232.58, 246, 11.7, 31.7, and 277.07 Bq kg(-1) for profile B, respectively. The eTh and eU were estimated to detect the migration process of uranium into or out of an area or uranium to or from the studied profiles. The results indicate a migration of uranium by 29% for profile A and 65.37% for profile B. The activity ratio ((238)U/(226)Ra) was found to be 0.9 in profile A and 1.15 in profile B. These ratios coincide with the uranium migration processes. The responsible mass corresponding to the measured (226)Ra activity was also calculated. The radon activity concentrations for the two profiles are nearly 300 Bq m(-3). The emanation coefficient (η) was calculated from the ratio of the expected radon activity to the measured radon for the studied soil samples. The value of η was found to depend only on the radium activity regardless to soil formation.

    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.

    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

    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.

  3. 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

    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.

    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.

    Full Text Available Abstract. This econometric study seeks to determine the most important factors of aggregate demand in Egypt so as to provide insight into how this developing nation can grow economically in the coming years. The Ordinary Least Squares estimation method was used in order to estimate nominal GDP for the time period 1975 to 2009. Based on the results the real interest rate, the inflation rate, the growth rate of government expenditure, and the growth rate of the money supply are the most statistically and economically significant factors of the growth rate of nominal GDP for the coming year. A one percent change in the growth rate of the previous year government expenditure is predicted to cause the growth rate of the current year nominal GDP to increase by 54%.The role of government expenditures on public sector wage expansion is discussed in this study as to shed light on this factor’s significant influence on income inequality post-1975 in Egypt, which will continue to impact nominal GDP and social conditions for the developing nation in the coming years.Keywords.

    2005-01-01

    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...

    The information and viewpoints presented at the Seminar on Egypt Population Policy held in Cairo on October 16-18 were summariezed and critically assessed. The seminar was organized by the International Union for the Scientific Study of Population's Committee on the Utilization ofDemographic Knowlege in Policy Formulation and Planning for the purpose of assessing the policy making the utility of social science and demographc knowledge with specific reference to Egypt's family planning program. The seminar was attended by demographers, social scientists, and experienced policy makers, and the discussion was highly focused. Seminar papers and discussions sought to clarify Egypt's current demographic situation, attempted to use sample survey data to identifyfertility determinants, analyzed Egypt's policyresponses to the population problem, assessed the national family planning program, identified the type of knowledge available for policy making, and noted areas where policy relevant information is lacking. Evidence presented at the seminar indicated that Egyptian fertility is still high and that corrected the total fertility rate for 1980 was close to 6. Since, 1960, fertility declined in all regions of the country, but between 1976-80 the decline decelerated. This deceleration appears to be a temporary phenonemon. There is evidence that the age at marriage is increasing, that the population is motivated to use contraception when desired family size is reached, that contraceptive use is cost sensitive, and that the overall decline in fertility since the 1960s occurred in all parts of the country. Papers which presented analyses of fertility determinants, based on sample survey data, provided little useful insight for policy formulation. The studies indicate that the impact of family planning services on different segments of the population varies, and that these impacts may be increased if social and economic development persists.

    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.

    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.

  19. Short-Time Effects on Eigenstate Structure in Sinai Billiards and Related Systems

    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...

  3. 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.

  4. 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.

    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.

  6. 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

    Nine archaeological bitumens from excavations in Canaan, Sinai and Egypt (Tel Irani, Ein Zik, Palmahim, Tel Arad, Jerusalem, Ein Besor-Site H, Sheik Awad and Maadi), dated 3900-2200 Bc. And two natural asphalts of the Dead Sea area (Ein Gedi floating blocks and Nahal Heimar) have been compared using the following geochemical techniques: chloroform extraction and GC and GC-MS analyses of C 15+ alkanes and C 15+ aromatics, isotopic analysis (δ 13C and δD) on chloroform extracts and asphaltenes and Rock-Eval pyrolysis of the insoluble organic residue. All samples are genetically related and are different from other archaeological bitumens from Syria and Iraq. Tel Irani archaeological bitumen was found to be identical to the floating block asphalts of the Dead Sea. Other archaeological bitumens were recognized as having been weathered and biodegraded to various degrees at archaeological sites in the course of the millennia. They are regarded as counterparts of floating block asphalts altered by aging. This study is the first evidence of the trade and export of raw bitumens from the Dead Sea area within Canaan and to Egyptian trading centers on the mainland route to Egypt between 3900 and 2200 BC, prior to the extensive utilization of bitumen for mummification in ancient Egypt.

  9. Surgical pathology in the 20th century at the Mount Sinai Hospital, New York.

    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

    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 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

    Radionuclidic concentrations in Al-Arish city area, north Sinai, Egypt, were measured. 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

    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.

    2013-03-01

    We study properties of a random walk in a generalized Sinai model, in which a quenched random potential is a trajectory of a fractional Brownian motion with arbitrary Hurst parameter H, 0segment of length L of such a chain decay as L-(1-H), independently of k, which suggests that despite a logarithmic confinement the average current is much higher than its Fickian counterpart in homogeneous systems. Our results reveal a paradoxical behavior such that, for fixed n and L, the mean-square displacement decreases when one varies H from 0 to 1, while the average current increases. This counterintuitive behavior is explained via an analysis of representative realizations of disorder.

  18. Selection of groundwater sites in Egypt, using geographic information systems, for desalination by solar energy in order to reduce greenhouse gases

    Mariam G. Salim

    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.

  10. Toward replacement fertility in Egypt and Tunisia.

    Science.gov (United States)

    Eltigani, Eltigani E

    2009-09-01

    Egypt and Tunisia began their fertility transition at almost identical fertility levels and at roughly the same time period, yet the difference in the pace of decline has been such that the total fertility rate (TFR) in Tunisia reached replacement level by the year 2001, whereas the TFR in Egypt remains above three live births per woman. This article draws on the secondary literature and on several nationally representative surveys from the two countries between 1978 and 2005 to provide empirical evidence of the difference in the pace of fertility decline and to analyze the determinants of the differential. Findings include (a) variation across the two countries in the consistency of fertility decline among the segments of the population leading the transition; (b) that the success of each country's family planning program was influenced by the role of political leaders and the extent of the program's integration within socioeconomic development objectives; (c) that the impact of contraception on TFR decline became an important factor in the mid-1980s; and (d) that the greatest determinant of the discrepancy in the pace of fertility decline is the disparity in age at marriage, which rose more significantly in Tunisia than in Egypt. The latter finding indicates that reaching replacement fertility in Egypt hinges primarily on further declines in marital fertility, resulting from reduction of wanted fertility and from an expansion of family planning program coverage and improved efficiency of service delivery and use.

  12. 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.

    2013-12-01

    The groundwater flow and potentiality for groundwater accumulation in the fractured basement rocks and the overlaying alluvial deposits were examined in Wadi Feiran basin using remote sensing (Landsat ETM, Ikonos, and Envisat, TRMM, and SIR-C radar images), field (well location, depth to water table), and geophysical (Very Low Frequency [VLF], magnetic) datasets. Our approach encompassed the following steps: (1) head data from 52 wells was utilized to build an approximate potentiometric surface map for the basin; (2) Landsat ETM, 3D, hill shade, Ikonos and SIR-C radar images were used to delineate structures in the study area including faults and dikes; (3) major precipitation events were identified from three-hourly TRMM data; and (4) false color composite images were generated from pairs of multi-temporal Envisat images acquired before and after a precipitation event (17th and 18th of January 2010) to identify structures (faults and dykes) that show an increase in moisture content and radar reflectivity following precipitation events and persisting for periods of days to months. Examination of the radar images revealed: (1) a network of highly reflective interconnected structures and channels (wadis) that are here interpreted to indicate preferred groundwater flow direction in the study area; and (2) many of the identified highly persistent reflective structures were found to be sub-parallel (hereafter referred to as low angle) to groundwater flow directions indicating that they are exceptionally conducive to groundwater flow. We suspect that groundwater flow occurs along low angle faults and dykes within the fault damaged zones and the weathered borders of mafic dykes. These suggestions are further corroborated by: (1) VLF results that showed significant dip angles (up to 60%) indicative of presence of shallow sub-vertical, sheet-like conductors across the identified low angle faults and dykes, (2) the presence of groundwater accumulation down gradient, along the terminal sections of the identified low angle faults; in these areas permeability decreases and groundwater is expelled; and (3) many of the existing wells and the ancient archaeological sites are located in areas that were identified as potential well locations based on the conceptual model described above.

    2012-04-01

    Wadi El Arish is the largest drainage system in Sinai Peninsula, Egypt. The Wadi was subject to severe thunderstorms on 17 and 18 January 2010 followed by an extreme and violent flood that had not been known in Sinai since 1980. The flood claimed six victims, injured tens of people, and devastated vital infrastructure and hundreds of houses. Hydrologic characteristics of the Wadi are not fully understood due to substantial lack of the detailed hydro-meteorological information. Hence, remote sensing and GIS techniques were used to provide better spatial understanding of rainfall characteristics and drainage basin response. The study was based on the analysis of the TRMM images and 6 hourly average HYDIS data of rainfall analyses. A hydrological model was constructed using ASTER DEMs. The empirical black box model was used depending on the curve number approach to predict stream runoff. Landcover and hydrological soil groups were identified from the Landsat ETM+ mosaic using multispectral supervised classification. The curve numbers were adjusted to ARC I (dry condition) as the total rain in a 5-day period preceding the storm were very low (≤5 mm). We found, that the Wadi received a total rain volume of 665.4 x 106 m3. Most of it fell on 17 January, when the rain intensity ranged between 4-8 mm/hr. The estimated total surface runoff Q was 123.3 x 103 mm and the total runoff volume was 124 x 106 m3 that constitutes 18.8 % of the total rain volume. The results are in agreement with the observed values in the Wadi and highly required for many applications related to water harvesting and flood protection studies.

    2014-02-01

    Full Text Available The asymmetric simple exclusion process (ASEP has become a paradigmatic toy-model of a non-equilibrium system, and much effort has been made in the past decades to compute exactly its statistics for given dynamical rules. Here, a different approach is developed; analogously to the equilibrium situation, we consider that the dynamical rules are not exactly known. Allowing for the transition rate to vary, we show that the dynamical rules that maximize the entropy production and those that maximise the rate of variation of the dynamical entropy, known as the Kolmogorov-Sinai entropy coincide with good accuracy. We study the dependence of this agreement on the size of the system and the couplings with the reservoirs, for the original ASEP and a variant with Langmuir kinetics.

    Full Text Available The literature on the causes of how terrorist organizations are formed and how counter terrorism measures can be more effective is immense. What is novel in terrorism literature is de-radicalization in terrorist organizations. This paper hopes to shed light on the de-radicalization process in terrorist organizations based in Egypt. In order to achieve that goal, the first part of the paper will deal with the de-radicalization process. The second part will briefly describe the major radical terrorist organizations that are effective in Egypt. The last part will combine the two parts and bring in suggestions on the de-radicalization process itself. Terrorism and de-radicalization are complicated threats to nearly all societies. Therefore, it is important to go beyond security and intelligence approaches and take proactive measures. It is best to view what is de-radicalization and how it can be achieved.

    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.

    2016-04-01

    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.

    2016-10-01

    Full Text Available Techniques were implemented to extract anthropogenic features in the desert region of North Sinai using data from the first- and second-generation Phased Array type L-band Synthetic Aperture Radar (PALSAR-1 and 2. To obtain a synoptic view over the study area, a mosaic of average, multitemporal (De Grandi filtered PALSAR-1 σ° backscatter of North Sinai was produced. Two subset regions were selected for further analysis. The first included an area of abundant linear features of high relative backscatter in a strategic, but sparsely developed area between the Wadi Tumilat and Gebel Maghara. The second included an area of low backscatter anomaly features in a coastal sabkha around the archaeological sites of Tell el-Farama, Tell el-Mahzan, and Tell el-Kanais. Over the subset region between the Wadi Tumilat and Gebel Maghara, algorithms were developed to extract linear features and convert them to vector format to facilitate interpretation. The algorithms were based on mathematical morphology, but to distinguish apparent man-made features from sand dune ridges, several techniques were applied. The first technique took as input the average σ° backscatter and used a Digital Elevation Model (DEM derived Local Incidence Angle (LAI mask to exclude sand dune ridges. The second technique, which proved more effective, used the average interferometric coherence as input. Extracted features were compared with other available information layers and in some cases revealed partially buried roads. Over the coastal subset region a time series of PALSAR-2 spotlight data were processed. The coefficient of variation (CoV of De Grandi filtered imagery clearly revealed anomaly features of low CoV. These were compared with the results of an archaeological field walking survey carried out previously. The features generally correspond with isolated areas identified in the field survey as having a higher density of archaeological finds, and interpreted as possible

RESULTADOS: Características peculiares da cultura da população surda apontaram a necessidade de adaptações na metodologia de aplicação de grupos focais quando compostos por pessoas surdas. As convenções ortográficas da escrita das línguas sinalizadas não estão consolidadas, o que trouxe dificuldades em registrar graficamente as etapas de tradução. As estruturas linguísticas que causaram maiores problemas de tradução foram as que incluíram expressões idiomáticas do português, muitas sem conceitos equivalentes entre o português e a Libras. Foi possível construir um software do WHOQOL-BREF e WHOQOL-DIS em Libras. CONCLUSÕES: O WHOQOL-BREF e o WHOQOL-DIS em Libras possibilitarão que os surdos se expressem autonomamente quanto a sua qualidade de vida, o que permitirá investigar com maior precisão essas questões.

  9. 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)

  11. 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

    1982-01-01

    The 1st application of the marketing audit concept to a CSM project was implemented in Egypt's Family of the Future (FOF) contraceptive social marketing program in 1982. The audit defined the basic mission of the FOF as one of assisting the government in achieving its long range family planning goals. The stated FOF objectives are as follows: to create an awareness or an increase in demand for family planning services, particularly among the lower socioeconomic strata in urban Egypt; to establish and maintain a reliable supply mechanism to make FOF products more readily acceptable and available from pharmacies; and to consolidate the CSM operations and services first in the greater Cairo area and then expand to other urban areas in Egypt. The core strategy of the FOF incorporates several elements, including intensive media based advertising and personal promotion to promote the concept of family planning and to educate the general public about contraceptive alternatives. FOF product prices are considerably lower than commercial prices. Dr. Alan R. Andreasen, who conducted the audit on behalf of the FOF technical assistance contractor, noted that the FOF is growing rapidly and stated that the audit recommendations were intended to help FOF management. Dr. Andreasen conducted interviews with all the senior personnel at FOF and met with various specialized staff members such as the Public Relations Manager. Dr. Andreasen noted that at the time of the audit the FOF could claim major accomplishments in creating an awareness of the need for family planning and in product sales. From the time products were launched in 1979 through 1981 condom sales increased 260%. Foaming tablet sales increased more than 320% and IUD sales increased nearly 330%. The introduction of the Copper 7 IUD accounted for 35% of the growth of IUD sales in 1981. Couple years of protection (CYP) provided by all products increased from 45,533 in 1979 to 190,831 in 1981, an increase over 300%. The

    Science.gov (United States)

    McKim Malville, J.

    Nabta Playa may contain the oldest human-made features with astronomical alignments in Egypt. In the Late and Terminal Neolithic (7,500-5,400 BP), nomadic pastoralists built a ceremonial center on the western shore of Nabta Playa, consisting of some 30 complex megalithic structures, stone circles, and lines of megaliths crossing the playa. The megaliths may once have aligned with Arcturus, the Belt of Orion, Sirius, and α Cen. Reorientations of the northern set of megaliths suggest a response to precession. Elaborate burials at the nearby cemetery at Gebel Ramlah indicate the nomads consisted of Mediterranean and sub-Saharan populations with little social stratification.

    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.

    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.

  20. 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

    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.

  2. Chapter 3: neurology in ancient Egypt.

    Science.gov (United States)

    York, George K; Steinberg, David A

    2010-01-01

    Neurology, in the modern sense, did not exist in ancient Egypt, where medicine was a compound of natural, magical and religious elements, with different practitioners for each form of healing. Nevertheless, Egyptian doctors made careful observations of illness and injury, some of which involved the nervous system. Modern scholars have three sources of information about Egyptian medicine: papyri, inscriptions, and mummified remains. These tell us that the Egyptians had words for the skull, brain, vertebrae, spinal fluid and meninges, though they do not say if they assigned any function to them. They described unconsciousness, quadriparesis, hemiparesis and dementia. We can recognize neurological injuries, such as traumatic hemiparesis and cervical dislocation with paraplegia, in the well known Edwin Smith surgical papyrus. Similarly recognizable in the Ebers papyrus is a description of migraine. An inscription from the tomb of the vizier Weshptah, dated c. 2455 BCE, seems to describe stroke, and Herodotus describes epilepsy in Hellenistic Egypt. We have very little understanding of how Egyptian physicians organized these observations, but we may learn something of Egyptian culture by examining them. At the same time, modern physicians feel some connection to Egyptian physicians and can plausibly claim to be filling a similar societal role. PMID:19892106

    This article uses an examination of the 1791 plague in Egypt to explore the relationships among disease, famine, flood, drought, and death in late eighteenth-century Egypt. It analyzes how plague functioned as part of a regular biophysical pathology of the environment in which the disease came and went as one iteration in a cycle that included famine, wind, flood, drought, price inflation, and revolt. Using the works of Egyptian chroniclers, archival materials, secondary studies, and traveler accounts, this article integrates plague into the study of the Egyptian environment by showing how it was a regular and expected part of life in Egypt.

    1985-01-01

    There are 2 features of Egypt's National Control of Diarrheal Diseases Project (NCDDP) that are central to its effective management: the NCDDP enjoys a certain degree of autonomy to the extent that it can reach beyond the Ministry of Health to bring in specialists through grants and contracts, and it has the power to manage its own budget and personnel; and the NCDDP is not a group of separate program elements but an integration of elements -- training of health workers; production, distribution, and marketing of oral rehydration salts (ORS); monitoring and evaluation of the project; and education and promotion via television, radio, and other public media. 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.

  8. 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.

    2015-01-01

    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.

    2012-01-01

    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.

    We are hereby reporting a case where the eggs and adults of the mold mites; Tyrophagus putrescentiae (Shrank) and the trophozoites of Blastocystis sp. were found in stool of three years old child from Minia City, Egypt. Intestinal mite infection was diagnosed after repeated identification of mite' stages from six consecutive stool samples to exclude the possibilities of contamination and spurious infection. The patient was suffering from severe colicky abdominal pain and burning sensation around the anus one month ago. All other members of his family were having the same acarine in their feces, but were all symptomless. The patient was treated with ivermectin 200 µg/kg body weight once every 10 days for three doses. His cure indicated that he was having asymptomatic blastocystosis. PMID:26788440

  17. 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

  18. 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

  19. 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

    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

    Full Text Available This paper explores some of the ways that the Internet, and particularly the practice of blogging, has opened up new political possibilities in Egypt. 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.

  8. Who Benefits from Public Healthcare Subsidies in Egypt?

    Directory of Open Access Journals (Sweden)

    Ahmed Shoukry Rashad

    2015-11-01

    Full Text Available Direct subsidization of healthcare services has been widely used in many countries to improve health outcomes. It is commonly believed that the poor are the main beneficiaries from these subsidies. We test this hypothesis in Egypt by empirically analyzing the distribution of public healthcare subsidies using data from Egypt Demographic and Health Survey and Egypt National Health Accounts. To determine the distribution of public health care subsidies, we conducted a Benefit Incidence Analysis. As a robustness check, both concentration and Kakwani indices for outpatient, inpatient, and total healthcare were also calculated. Results show some degree of inequality in the benefits from public healthcare services, which varied by the type of healthcare provided. In particular, subsidies associated with University hospitals are pro-rich and have inequality increasing effect, while subsidies associated with outpatient and inpatient care provided by the Ministry of Health and Population have not been pro-poor but have inequality reducing effect (weakly progressive. Results were robust to the different analytical methods. While it is widely perceived that the poor benefit the most from health subsidies, the findings of this study refute this hypothesis in the case of Egypt. Poverty reduction measures and healthcare reforms in Egypt should not only focus on expanding the coverage of healthcare benefits, but also on improving the equity of its distribution.

  9. Future studies and research in Egypt. Overview, examples, perspectives

    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.

    Egypt has been one of the developing countries following successful programs for the development of renewable energy resources, with special emphasis on solar, wind and biomass. Utilization of biomass as a source of energy is important from energetic as well as environmental viewpoint. Furthermore, Egypt produces millions of biomass waste every year causing pollution and health problems. So, the incorporation of biomass with other renewable energy will increase the impact of solving energy and environmental problem. There is a good potential for the utilization of biomass energy resources in Egypt. Four main types of biomass energy sources are included in this study: agricultural residues, municipal solid wastes, animal wastes and sewage sludge. Analysis of the potential biomass resource quantity and its theoretical energy content has been computed according to literature review. The agriculture crop residue represents the main source of biomass waste with a high considerable amount of the theoretical potential energy in Egypt. Rice straw is considered one of the most important of such residue due to its high amount and its produced energy through different conversion techniques represent a suitable candidate for crop energy production in Egypt.

  11. Egypt's Policy Concerning Food Irradiation Research and Technology

    International Nuclear Information System (INIS)

    The paper reviews current research in Egypt in the field of radiation preservation of food to accumulate the necessary data for drafting Egypt's policy towards prospects for application. Research activities in Egypt have been oriented to solving problems of local economic importance, e.g. inhibition of sprouting in potatoes, onions and garlic, extension of shelf-life of vegetables and fruits, disinfestation of stored grains and grain products, preservation of meat, meat products, fish, fats and oils, and elimination of parasites and microorganisms from animal feed. Extensive studies have been performed to determine the lowest radiation level required for short-term storage, changes in organoleptic, physical, chemical and microbiological values of irradiated food and wholesomeness studies to give evidence of the safety of irradiated food for human consumption. The paper summarizes Egypt's national planning for the transfer of such new technology, the establishment of the National Centre for Radiation Research and Technology to build up the national infrastructure for food irradiation research and application, and the formation of a Supreme Committee for Radiation Preservation of Food. Finally, the paper also surveys the locally available irradiators and correlates the design, capacity and capital cost against the actual needs of Egypt and the experience acquired. (author)

  13. 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

  14. Identifying the Practice of Tattooing in Ancient Egypt and Nubia

    Full Text Available Tattooing was practised by many ancient societies, including the ancient Egyptians and Nubians. Egypt, for example, boasts iconographic and physical evidence for tattooing for a period spanning at least 4000 years – the longest known history of tattooing in the world. The second oldest physical evidence for tattooing worldwide was recovered from Middle Kingdom contexts in Egypt and C-Group contexts in Nubia (the Hanslabjoch ice man being the oldest. It has been suggested that tattooing was also practised in the Predynastic period as evidenced by figurines with geometric designs, however, no physical evidence for tattooing has yet been found for this early period. Strangely there is almost no mention of tattooing in ancient Egyptian written records. Historical and ethnographic records indicate that tattooing was also practised much more recently in the Coptic, Islamic and modern eras. Unlike many past societies, tattooing in Egypt appears to have been a custom practised almost exclusively on women. Tattooing tools have not yet been positively identified from ancient Egypt. Ethnographic sources suggest that bundles of metal rods were used in Egypt’s more recent history. This paper discusses physical and iconographic evidence for tattooing in ancient Egypt and investigates whether five copper rods found at Kafr Hassan Dawood, a Predynastic to Early Dynastic site in the East Delta, could be physical evidence for tattooing during this early period.

    2015-12-01

    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.

  16. 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).

  17. 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)

    2008-04-01

    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.

  20. Television minidramas: social marketing and evaluation in Egypt.

    Science.gov (United States)

    Lane, S D

    1997-06-01

    Television has been extensively used to communicate health messages for over a decade in Egypt. Viewers of the evening soap operas have been seeing six commercials for family planning, oral rehydration solution (ORS), and immunizations. People of all social classes can sing the jingles of the most popular ads. The producers of these health spots use increasingly sophisticated story lines, settings, and characters representing rural peasants, played by popular and well-liked actors. Evaluation of the content and impact of these messages has lagged behind the creative sophistication of their production. This article reviews the context and content of televised health messages in Egypt during the 1980s, critically assesses the evaluation of mass media health education, and suggests strategies for more effective evaluation. The author worked for some years with a private donor agency that funded the production of a number of televised health commercials in Egypt. PMID:9186959

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

    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

    In 1986, Egypt implemented a succession of comprehensive economic reforms both in the agriculture sector and more generally such as the Economic Reform and Structural Adjustment Program (ERSAP) of 1991. Since then, the agricultural sector has been gradually transformed from one characterised by central planning and governmental controls to one that is more free market oriented. This study employs the Policy Analysis Matrix technique to evaluate the impacts of reform policies on eleven maj...

  3. Biomphalaria alexandrina in Egypt: past, present and future.

    Science.gov (United States)

    Abou-El-Naga, Iman F

    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

    2015-10-01

    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

  10. 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.

  11. Determining Potential Sites for Runoff Water Harvesting using Remote Sensing and Geographic Information Systems-Based Modeling in Sinai

    Directory of Open Access Journals (Sweden)

    Hossam H. Elewa

    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.

  8. 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

  9. A Mediterranean Rio Grande. Regional report 1: Egypt.

    Science.gov (United States)

    1994-01-01

    This document concerns the impact of environmental problems on the economic life of people in Egypt and North Africa. With only a quarter of arable land, Egypt is incapable of feeding a population of 59 million people, and at the same time the economic condition has deteriorated. It has been estimated that Egypt needs to create about 450,000 jobs annually to keep up with additions to the labor force. Population growth, on the other hand, was projected to reach 81 million by 2010. In addition, Egypt is facing ever-growing water shortages with an estimate that within the next 20 years the demand for water will exceed the country's allotted share of Nile water by nearly 60%. Likewise, food shortages will likely be exacerbated by a continuous sea level rise through permanent flooding of agricultural lands. People in Libya, Tunisia, Algeria, and Morocco have migrated to Europe for several reasons: first, because of the steady population growth and unmet needs in family planning in these countries; second, because of the population pressures caused by the deterioration of the environment. Also, inadequate water supply has been affecting these countries. The prognosis for these countries must be cautious and conservative and their respective local governments must develop the programs that address these problems.

    Full Text Available Aim: The study was undertaken to understand the epidemiological status of bluetongue infection in Egypt. 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.

  14. 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

Determination of the study area, geographical features, facilities, difficulties, and key personnel from the same area are important factors for successful methodology. Over 31 months (July 1, 2009 to January 31, 2012, a screening and an examination survey were carried out to ascertain the prevalence of epilepsy, stroke, dementia, cerebellar ataxia, migraine, cerebral palsy, Parkinsonism, chorea, athetosis, dystonia, trigeminal neuralgia, Bell's palsy, multiple sclerosis, spinal cord disorders, and attention deficit hyperactivity disorders in Al Quseir, Red Sea Governorate, Egypt. A total of 33,285 people were screened by three neurologists in a door-to-door manner, including every door, using a standardized Arabic questionnaire to detect any subject with a neurological disorder. The methodological aspects of this project were carried out through eight phases: (1 data collection; (2 preparation; (3 screening; (4 case ascertainment; (5 investigations; (6 classifications; (7 data entry; and (8 statistics and tabulations. The results of this study reveal that the total prevalence of neurological disorders in Al Quseir was 4.6% and higher among females (5.2% than males (3.9%.

  16. 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

    and gas pools mainly vvithin the Upper and Lower Cretaceous. 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

    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

  6. Chromosomal and C-heterochromatin Characterization of Arvicanthis niloticus (Rodentia: Murinae in Egypt

    Mahmoud I. Shoulkamy

    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.

    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.

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.

    This work describes the concentrations of radioisotopes in soil, sediment, wild plants and groundwater in southwestern Sinai. The study area extends from Suez to Abu Rudies along the eastern part of the Suez Gulf. It included two hot springs: Ayun Musa and Hammam Faraoun. No dependence of ¹³⁷Cs concentrations on any of the measured sand characteristics was found, including calcium carbonate. The enrichment of ²²⁶Ra in Hammam Faraoun hot spring was the most prominent feature. The ²²⁶Ra concentration in hot springs of Ayun Musa and Hammam Faraoun were 68 and 2377 Bq kg⁻¹ for sediments, 3.5 and 54.0 Bq kg⁻¹ for wild plants and 205 and 1945 mBq l⁻¹ for the groundwater, respectively. In addition, ²²⁶Ra activity concentration in local sand in the area of Hammam Faraoun was ∼14 times that of Ayun Musa. On the other hand, the ²³²Th concentrations were comparable in the two hot springs, while ¹³⁷Cs concentrations were relatively higher in Ayun Musa. The characteristics and radioelements studies support possible suggestions that the waters in the two hot springs have different contributions of sea and groundwaters crossing different geological layers where the water-rock interaction takes place.

    The Egyptian government is preparing a sustainable development master plan for the Ras Muhammed National Park (RMNP), south Sinai. 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.

  15. 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.

    Rising rates of invasive fungal infections may be linked to global climate change. A study was made of the trend of ophthalmic fungal corneal keratitis in the greater Cairo area of Egypt and its association with climate records during the same period. Data on diagnosed cases of fungal keratitis were collected from records of ophthalmic departments of Cairo University hospital and atmospheric temperature and humidity for the greater Cairo area were obtained from online records. Statistical analysis showed a significant increase in the relative frequency of keratomycosis during 1997-2007. The rise correlated significantly with rises n min,mum temperature and the maximum atmospheric humidity in the greater Cairo area over the same period (after exclusion of the effect of the maximum atmos pheric temperature). The predicted increase in keratomycosis up to the year 2030 corresponds to predicted increases in CO2 emissions and surface temperature from climate change models for Egypt.

    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

    International Nuclear Information System (INIS)

    The aim of this work is to examine the marketing , economic and financial feasibility of a project for garlic irradiation in Egypt. The Egyptian market of garlic was described and analyzed considering the production size distributed over several years, methods of preservation and storage, percentage of loss and cost for each method and distribution channels. The financial and economic analysis of the establishment of A tote Box unit for the irradiation of garlic was also carried out. The following investment criteria were utilized for the commercial evaluation : benefit-cost ratio, payback 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 garlic in Egypt would be economically viable. The unit cost of irradiation would decline if the irradiator is used as a multipurpose facility

    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

    2014-12-01

    Full Text Available This paper summarizes the results of energy simulation analysis to determine the effectiveness of building characteristics in reducing electrical energy consumption for hotel buildings in Egypt. Specifically, the impact on building envelope performance is investigated for different strategies such as window size, glazing type and building construction for two geographical locations in Egypt (Cairo and Alexandria. This paper also studies the energy savings in hotel buildings with 200 rooms for different Lighting Power Densities (LPD, Energy Input Ratios (EIR, Set point Temperatures (SPT and HVAC systems. The study shows certain findings of practical significance, e.g. that a Window-to-Wall Ratio of 0.20 and reasonably shaded windows lower the total annual electricity use for hotel buildings by more than 20% in the two Egyptian locations.

    2010-01-01

    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.

  2. Regional and national radiation protection activities in Egypt

    International Nuclear Information System (INIS)

    Radiation protection activities in Egypt go back to 1957 where the Egyptian Atomic Energy Commission (EAEC) Law was issued. Radiation protection and civil defense department was one of EAEC eighth departments. Ionizing radiation law was issued in 1960 and its executive regulation in 1962. The main aim of the present work is to through some light on the current radiation protection activities in Egypt. This includes not only the role of governmental organizations but also to the non governmental organizations. Currently a new Nuclear Safety law is understudy. Regional activities such as holding the second all African IRPA regional radiation protection congress which was held in April 2007 and national training and workshops are held regularly through EAEA, AAEA and MERRCAC.

    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.

  14. 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.

    1992-01-01

    The origins of the feminist movement in Egypt can be traced back to the social restructuring that occurred during the reign of Mohammed Ali (1805-48). At that time, a debate raged over whether female education was essential to national development. Reformers such as Kassim Amin argued in favor of education for all women and condemned polygamy, supporting their arguments with references to the Koran. Women from the upper classes used their wealth, over which Muslim law gives them full control, to found hospitals, schools, and training centers. By 1914, there were 14 magazines devoted to women's issues. Women participated in anticolonial movements and nationalist party activities while continuing to advocate improvements in women's status. In 1924, Egypt became the 1st Islamic country to deveil women without state intervention. The Egyptian Feminist Party was founded in 1923, and the Women's Political Party was established in 1942 to coordinate the fight for women's equality and the revision of family law. Women's full political rights gained recognition when Egypt won independence in 1956, and the 1st female Minister, Hekmat Abu-Zaid, was appointed in 1962. Ironically, the feminist movement stagnated in the 1st few decades after independence as women's organizations became coopted into the state. The movement has been revitalized, however, by Islamic attacks on women's rights. PMID:12317569

    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.

    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.

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

We aimed to determine the prevalence and underlying causes of recurrent/persistent pneumonia in children in Upper Egypt. Settings: Assiut University Children Hospital, Assiut, Egypt.   Methods: Patients with pneumonia admitted to the hospital during 2 years were investigated (microbiological, biochemical, immunological and radiological tests for recurrent/persistent pneumonia to determine its prevalence and to find out the underlying causes.   Results: 113 out of 1228 patients (9.2% met the diagnosis of recurrent/persistent pneumonia. Identified causes were;  aspiration syndromes (17.7%, pulmonary TB (14%, congenital heart disease (11.5%, bronchial asthma (9.7%, immune deficiency disorders (8.8% and vitamin D deficiency rickets (7%. Other causes included; congenital anomalies of the respiratory tract, interstitial lung diseases, bronchiectasis, and sickle cell anemia. No predisposing factors could be identified in 15% of cases. Conclusion: Approximately 1 in 10 children with pneumonia in our locality had recurrent/persistent pneumonia. The most frequent underlying cause for recurrent/persistent pneumonia in children in Upper Egypt is aspiration syndromes, followed by pulmonary TB.

    1988-01-01

    Structure and stratigraphic mapping in the northern half of the Gulf of Suex (GOS) documents two en echelon, rift-parallel (Clysmic trend) rift segments. The segments are right stepping and share a zone of overlap, which extends southward from the southern border of the Wadi Araba structure on the western shore of the gulf to the north end of the Abu Durba block on the east side of the gulf. The spatial relationship of the two segments defines the central GOS rift offset, and the structural depression linking the segments in the area of overlap forms a rift-offset zone. Another potential rift offset, though less well constrained, also with a north-south trend may be present south of Gebel Zeit. This rift and the central GOS rift offset provide a model for the opening of the GOS in which north-south rift-offset zones link Clysmic-trending rift segments, imparting a regional zig-zag pattern to the initial rift configuration. Recognition of offset zones and their associated fault fabrics is essential for effective exploration of rift basins. For example, the alignment of producing fields and elongation directions of individual fields in the central GOS offset are anomalous relative to those of other producing trends in the Gulf.

    We study the classical and quantum correspondence for a two-dimensional Sinai billiard system. By using the Stationary state expansion method and Gutzwiller’s periodic orbit theory, we analyze the quantum length spectrum obtained through the Fourier transformation of the quantum density of state for the Sinai billiard system, and by comparing the peak position with the length of the classical periodic orbit we find their excellent correspondence. We observe that some quantum states are localized near some short period orbits, forming the quantum scarred states or superscarred states. In this paper we also investigate the nearest-neighbor spacing distribution of levels for both concentric and nonconcentric Sinai billiard systems, and find that the concentric Sinai billiard system is nearintegrable, and for the nonconcentric Sinai billiard system withϑ=3π/8 its nearest-neighbor spacing distribution of levels transits from nearintegrable to the Wigner distribution as the distance between the two centers increases.%研究了二维Sinai台球系统的经典与量子的对应关系,运用定态展开法和Gutzwiller的周期轨道理论对Sinai台球系统的态密度经傅里叶变换得到的量子长度谱进行分析,并把量子长度谱中峰的位置与其所对应的经典体系的周期轨道长度做对比,发现两者之间存在很好的对应关系。观察到了一些量子态局域在短周期轨道附近形成量子scarred态或量子superscarred态。还研究了同心与非同心Sinai台球系统的能级最近邻间距分布,发现同心Sinai台球系统是近可积的,非同心Sinai台球系统在θ=3π/8下,随两中心间距离的增加,能级最近邻间距分布将由近可积向维格那分布过渡。

    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

    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

    This qualitative study investigated the influence of family support on women's health-seeking behavior in rural southern Egypt (Upper Egypt). We carried out separate focus group discussions (FGDs) with 3 groups (6 women with children under 5 years old, 6 men, and 4 elderly women, respectively) in a village in Assiut Governorate, an underprivileged region in Upper Egypt. The FGDs aimed to identify how different types of family support affected women's health-seeking behavior in areas including maternal health and common illnesses of women and children. Our results showed that maternal health issues were often discussed by husbands and wives, while mothers-in-law had little apparent influence. We also found that women could access support resources more easily than expected through their extended families. Our study showed that husbands had an important role in encouraging women's health in the family, while the effect of mothers-in-law on women's health-seeking behavior was not substantial. The study indicated that women received considerable support from co-resident family members, their natal family, and their neighbors, which helped women in seeking health services. PMID:25129988

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

    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

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

    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.

    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

    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.

    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.

    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

    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

    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.

    Full Text Available O gás natural possui alguns contaminantes que, além de serem corrosivos, comprometem a qualidade para o consumo. 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. As câmeras fornecem imagens, que são processadas digitalmente e gravadas em uma memória não-volátil. Um software desenvolvido para tal finalidade é utilizado na verificação das imagens e, ao mesmo tempo, na identificação das não-conformidades presentes e na orientação do processo de manutenção.

    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.

    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.

    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.

    Started in 1979 as part of the International Planned Parenthood Federation (IPPF), the Family of the Future (FOF) social marketing project accounts for 35% of all contraceptives used in Egypt. FOF left the IPPF in 1981 to work as a nonprofit, semiprivate organization under the supervision of Egypt's Ministry of Health and has become the third largest social marketing project in the world. FOF has, however, gone through 5 executive directors in the last 6 years, prompting critics to think that the Board of Directors is hand-picked by the Egyptian Ministry of Health. additional allegations of financial mismanagement have caused the U.S. Agency for International Development (USAID) to cancel over $1.5 million in annual funding and product support for the program. Until recently, FOF has benefited from products and operations and technical assistance totalling near $20 million as part of a USAID 10-year, $118-million Egyptian effort. FOF has responded to the funding cut by downsizing its staff and preparing to raise contraceptive prices. Even though USAID has solicited proposals for competitive replacement programs, the new executive director is optimistic that funding cuts leading to organizational change and price increases will ultimately help FOF become self-sufficient. Once USAID-provided supplies have been depleted, FOF will most likely turn to IPPF for assistance.

    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

    2015-08-01

    Schistosomiasis has plagued the Egyptian population since the antiquity. The disease is still a public health problem in Egypt, despite the tendency of being overlooked. In the first part of this review, the past and current trends of schistosomiasis in Egypt are reviewed, including history, epidemiology, morbidity, therapy, and control of the disease. Most of these aspects are more or less relevant to other schistosome-endemic regions all over the world. As only one drug is currently available for individual treatment and preventive mass chemotherapy, the quest for complementary measures is urgently warranted. Indeed, one promising approach is the discovery of a vaccine. Herein, we point out the efforts of the Egyptian scientists to develop an efficacious and affordable vaccine against schistosomiasis - a step forward in the battle of elimination of Schistosoma infection. Based on the candidate vaccine antigens, four types of vaccine formulations are discussed: purified antigen vaccines, DNA constructs, attenuated cercariae, and excretory-secretory antigen vaccines. Finally, this review provides insights into this ancient seemingly long-lasting parasitic disease. PMID:25959770

    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.

    1985-01-01

    The inexistence in the Arab world of institutions to facilitate development led Egypt to adopt the infitah, a policy of economic opening which is not a voluntarist economic strategy but rather is intended to create a climate favorable to a more capitalistic orientation for individuals with access to petroleum income. Egypt's gross national product grew by 4.6%/year in the dozen years through 1965, but thereafter growth was sluggish or even negative. After 1967 the choices of the dominant economic classes were oriented toward liberalism, and the arrival of Sadat allowed this orientation to prevail even before the infitah. The various measures of the infitah were designed to promote investment, reactivate the private sector, and reorganize the public sector. Most of the specific projects approved through 1978 were in the tertiary sector, they did little to stimulate further development, and the total number of jobs created was relatively insignificant. The transformation of the Egyptian economy is due not so much to the infitah as to 4 other elements: oil, income from the Suez canal, tourism, and emigration. At present petroleum represents 30% of Egypt's exports, the Suez canal will probably bring in $1.5 billion annually in coming years, and tourism brought in $1 billion in 1984, but in terms of economic and social impact on the total population emigration is much more important. The number of emigrants increased from 100,000 in 1973 to over 3 million in 1984 and the extent of their remittances increased from $184 million in 1973 to nearly $4 billion at present. Serious shortages of skilled and unskilled labor have been created by the departure of 10-15% of the overall labor force and a higher proportion for some skilled professions. The number of workers in construction more than doubled from 1971-79, while 10% of the agricultural labor force departed. Agricultural wages increased by an average of 7.1% in these years as agricultural workers were attracted to the

    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.

    The principal objectives of the energy assessment project for Egypt are to develop understanding of the current status of the principal energy users in Egypt's industrial and agricultural sectors; to estimate the energy demand and efficiency for each selected subsector within these major sectors; to identify opportunities for fuel type changes, technology switches, or production pattern changes which might increase the efficiency with which Egypt's energy is used both now and in the future; and based on options identified, to forecast energy efficiencies for selected Egyptian subsectors for the years 1985 and 2000. The areas studied in the industrial sector are the iron and steel, aluminum, fertilizer, chemical, petrochemical, cement, textile, and automotive manufacturing industries. Those studied in the agricultural sector concern drainage and irrigation, mechanization, and food processing. Additional information in 4 annexes include industrial/agricultural sector options; residential/commercial, transportation, and fossil fuels supply options.

  5. Assessment of radon levels in some water resources in Egypt

    International Nuclear Information System (INIS)

    Radon is a naturally occurring radioactive gas that is produced by the radioactive decay of radium. Breathing high concentrations of radon can cause lung cancer. When radon gas migrates through the atmosphere, the solid radon progeny are deposited on the soil and water below, entering into the food chain. Radon generated from rocks containing its parents may escape to the underground or surface running water, which ultimately used as drinking water or for irrigation. In this work radon level was determined in different water resources in Egypt. Water from spring, tap water Nile and some commercially available drinking water were subjected to radon measurements using CR-39 detectors. Radon concentration in different water resources was found the range from 8.94 to 10.00 Bq/m3 while in trapped air above water was 9.3 to 10.38 Bq/m3

  6. Provenance studies of pottery fragments from medieval Cairo, Egypt

    International Nuclear Information System (INIS)

    In the analysis of archeological pottery fragments, instrumental neutron activation analysis has been utilized to establish the elemental concentrations of up to 37 chemical elements for each of 53 archeological pottery samples from medieval Cairo, Egypt, and one additional sample of Chinese porcelain. These elemental concentrations have been utilized in a statistical analysis procedure in order to determine similarities and correlations between the various samples. Multivariate analyses have been used to quantitatively determine these interrelationships. This methodology successfully separated the Egyptian samples into two broad categories: polychrome decorated ceramic ware and monochrome celadon ware. In addition the methodology successfully identified the one unique sample of Chinese porcelain. Several samples appeared to be either a mixture of categories or outliers in the data set and were not attributable to any distinct category. (author)

    The Burullus Lagoon north Nile Delta of Egypt is a UNESCO-protected area. Recently it has become a sediment sink which led to shrinking in its area and depth accompanying with increasing contaminant levels. In this study we attempt to explore the spatial distribution and their mobility of heavy metals (Zn, Cu, Ni, Cr and Pb) based on 21surface sediment samples recovered from Burullus lagoon basin and nine drains. The risk assessment code of the studied heavy metals can be arranged as Zn>Cu>Pb>Cr>Ni for all the samples collected from the lagoon basin and nine different drains. The heavy metals tend to accumulate in fine sediments and human activities promote the accumulation of contaminated sediments in water courses. PMID:27216045

    Amidst the recent political uprisings in the Arab region, physicians and other healthcare workers have found themselves in the crossfire. This paper focuses on Egypt's doctors, paying special attention to how many have both appealed to and practiced medical neutrality as its own potent and contested political stance, particularly since the period of military rule following Mubarak's removal from power. Our paper draws on interviews with physicians who served as volunteers in the field hospitals in the days of unrest and violence, and with others who played a major role in documenting protesters' injuries, police brutality, and other forms of state violence against unarmed citizens. Based on interviews with doctors who belong to organizations such as "Tahrir Doctors" and "Doctors Without Rights," our paper reveals how these doctors' commitment to professional ethics put them at odds with the orders of military personnel, rendering their appeal to "medical neutrality" a weighty political act in and of itself.

The regression coefficients (a and (b of Angstrom type correlation are calculated for the selected sites. The values of the regression coefficients are found to vary from 0.219–0.611 and 0.107–0.576, respectively. These values have been calculated by three different approaches. The estimated values of the global solar radiation are compared with the measured values. Although the (a and (b values differ from one site to another; the summation (a+b is almost the same for the selected sites. The difference between the estimated and measured values of the global solar radiation at the various sites varies from 4 % to 12 %.

    Soil in Egypt, especially around Delta is exposed to various pollutants which are affecting adversely soil fertility and stability. Humic Acids (HA) as a main part of soil organic matter (SOM) represent the heart of the interaction process of inorganic pollutants with soil. Consequently, Fourier transform infrared spectroscopy (FTIR) and Nuclear magnetic resonances (NMR) were used to characterize soil, sediment and extracted HA. Resulting data confirmed that the HA was responsible for transporting inorganic pollutants from surface to subsurface reaching the ground water, which may represent a high risk on public health. The transport process is coming as carboxyl in surface soil changed into metal carboxylate then transferred into the carboxyl in bottom soil. PMID:27294554

  15. Analysis of integrated geologic data for uranium exploration in Egypt

    International Nuclear Information System (INIS)

    Geologic information system (GIS) related to Nuclear Raw Materials is in current development in the Scient. Inform. Dept. (NMC). Processing of data follows developed criteria in U-exploration. Landsat image interpretation, photo lineaments, field measured joints, faults, folds, foliation, lineation, and deformed pebbles when properly integrated and computerized have pointed out a comprehensive tectonic model related to the CED of Egypt. The area seemed to be subjected to three deformative stages, in the first two; rocks undergone plastic deformation, while in the third one, rocks failed in brittle mode where the Red Sea Transverse Tectonic Trend (ENE-WSW) was developed intersecting the older plastically developed linear elements (NW-SE). Further rejuvenations permit opening the mentioned fractures and occupied by siliceous materials and jasperoid veins and lastly by U-type mineralization, best depicted in the plutons of El Missikat, El Erediya, Um Had and Kab Amiri. The Oligocene Qatrani Formation, north of Lake Qarun, NWD of Egypt is a typical example of fluviatile deposits. The middle clayey member is enclosed between two porous sandy members. The carbonaceous shale related to the clayey member shows abnormal U-concentrations. Statistical analysis of the distribution of uranium and other trace elements in the carbonaceous shale shows that U, Y, Mn and Ca obey the lognormal law while Sr, Rb, Zr, Cr and Ti obey the normal law. A geologic factor is derived that normally distributed elements are stationary, indigenous probably of detrital origin. Meanwhile, other lognormally distributed elements are active and mobile. Subsurface mapping shows that uranium tends to concentrate in the troughs of the flexured carbonaceous shale suggesting an epigenetic origin. 14 refs, 9 figs, 4 tabs

    Full Text Available In the present article the legal regulation of international commercial arbitration in Egypt evolution is researched, legal documents governing operation of international commercial arbitration, general characteristics is given, features of legal norms and legal regulation are pointed out, also legal practice of application is analyzed. Author points out that at first legislation of Egypt was under the strong influence of Islamic law, later the legal system in Egypt was subjected to extensive influence of European law. It is believed that it is the Sharia law that largely caused formation of goals and objectives of modern international commercial arbitration. The main source of the international commercial arbitration activities regulating is the adopted in 1994 Law of Egypt on Arbitration No. 27/1994 (the Arbitration Act. This law was adopted on the basis of the UNCITRAL Model Law on the International Commercial Arbitration (of the year 1985. Prior to the adoption of the Arbitration Act in the year 1994 the international commercial arbitration in Egypt was governed by the Civil Procedure Code, adopted in the year 1968. The Law of Egypt on arbitration contains several differences from the UNCITRAL Model Law. 1 The Model Law has a bit another internal structural division. Articles of the Egyptian Arbitration Act do not have name. The law includes 58 articles, united in 7 parts; 2 Ability of extraterritorial application. Arbitration Act applies to arbitrations conducted in Egypt or when the international commercial arbitration is conducted abroad and agreed to subordinate to this arbitration Act; 3 The Arbitration Act provides additional criteria for the establishment of the international character of arbitration.

    Full Text Available The purpose of this paper is to evaluate the behavior of monetary authorities in Tunisia and Egypt, in response to changes in macroeconomic variables over time based on LSTR model. In this sense, we estimate Taylor-type equations for short-term interest rate in Tunisia and Egypt using quarterly data covering the period 1998.Q4–2013.Q2. We find strong evidence that the real decision-making process followed by these central banks varies from one central bank to another and that it exhibits nonlinear patterns that better capture special events and unexpected contingencies i.e., the terrorist attack in the US in September 2001, the global financial crisis in 2008, and the effect of political instability with the onset of the revolution. Additionally, the presence of asymmetries in the reaction function of the Tunisian and Egyptian Bank requires disconnection from their automatic pilot rules and use of judgement to make decisions.

  6. Nile behaviour and Upper Palaeolithic humans in Upper Egypt

    Vermeersch, Pierre M.

    2014-05-01

    There is evidence of a decreasing human occupation of the Upper Egyptian Nile valley during the MIS 5 to MIS 3 period. Whereas very large extraction sites of the Middle Stone Age have been recorded, only very few sites of the Upper Palaeolithic have been found. The best explanation of this fact is that during the Late Middle Stone Age and the Upper Palaeolithc there was nearly no need for raw materials because there was only a very restricted population present in Upper Egypt. From about 22 ka BP an important population increase is registered by the presence of numerous Late Palaeolithic sites. During the whole LGM there is abundant presence of humans along the Nile Valley in Upper Egypt. This population was mainly living from fishing. There seems to be an abrupt end of the Palaeolithic occupation after 12.8 ka BP. Until now, no sites were found in the Valley until some rare Epipaleolithic sites occur about 8.0 ka BP. It will be suggested that these population changes are influenced by the river Nile behaviour. The best interpretation of the observations in the Upper Egyptian Nile Valley is the hypothesis that at the same time that Nile flow was reduced because of the dryness in its source area, the impact of aeolian activity was increased over Northeast Africa. The increased aeolian activity by northern winds in the Fayum and Wadi Ryan during the LGM resulted in the accumulation of aeolian sand in the valley. That aeolian sand was transported along the western Nile valley cliffs until it was accumulated when the Nile Valley change it S-N direction, such as at Nag'Hammadi. At other places sand was invading the Nile valley, directly from the Western Desert, creating a damming of the Nile at several places such as Armant and Aswan. As Nile flow was quite reduced, the Nile was unable to erode all the incoming sand and the Nile water with its important clay content was dammed. At several places large lakes were created in the Nile Valley. Those lakes were an ideal

  13. Geomorphology and Quaternary geology of the Dakhla Oasis Region, Egypt

    Science.gov (United States)

    Brookes, Ian A.

    Dakhla Oasis (25.5°N, 29°E) occupies a structurally localized depression at 90-140 m above sea level, ˜1200 km 2 in area, below a 300 m escarpment bordering the Libyan Plateau, Western Desert of Egypt. Semi-arid intervals of the Quaternary period generated eight sedimentary formations, separated by erosion during hyper-arid intervals. Sediments comprise three generations of colluvial/fluvial fanglomerates, two generations of tabular spring-laid clastic and chemical sediments, two generations of mound springs and basinal sediments. of fluvio-lacustrine, evaporitic, pluvio-aeolian and aeolian origins. Discussion of these sediments is organized according to geomorphic region, from north to south, plateau, scarp and piedmont, lowland and cuesta plain. Chronological evidence is restricted to many radiocarbon dates of Holocene cultural material associated with playa sediments (9-4.5 ka), a {Th}/{U} isochron age of ˜62.0 ±7.6 ka for basinal evaporites, and two {Th}/{U} ages of ˜176 and ˜170 ka for a boulder of derived travertine. The regional Quaternary sequence is reconstructed from stratigraphic and geomorphic relationships of the sediments and erosion surfaces. It is broadly similar to sequences earlier reconstructed in the topographically similar Kharga Oasis region 150 km to the east, and Kurkur Oasis, 400 km to the south-southeast. Speculations on chronology and driving mechanism are offered in conclusion.

    Early - or child - marriage (before age 18) may diminish women's ability to exercise agency, or their capacity to act upon their goals. Using a propensity score adjustment approach, we analyzed data from 2394 married women ages 35-49 years who participated in the 2006 Egypt Labor Market Panel Survey (ELMPS). We examined whether women's first marriage at age 18 or older was associated with their post-marital agency, measured in terms of their influence in family decisions, freedom of movement in public spaces, and unfavorable views about intimate partner violence against wives. In bivariate analyses, women's age at first marriage was positively associated with their decision-making and more equitable gender attitudes. However, once we controlled for selection into age-at-first-marriage groups, there were no significant differences between the two age-at-first-marriage groups in any dimension of women's agency. We examined the sensitivity of the non-significant age-at-first-marriage effects to possible violations of the strong ignorability assumption and the results did not alter our conclusions. The assumption that women's age at first marriage is a proxy for their post-marital agency, as defined here, warrants further study. PMID:26973037

  15. Site Characteristics For Long Term Storage in Egypt

    International Nuclear Information System (INIS)

    This work deals with the establishment of a new guideline for a new disposal for low and intermediate radioactive waste in Egypt. It is only permitted in natural geological formations with acceptable seismic and tectonic parameters. The representative parameters applied for this evaluation are related to the release process of the strain energy. The examined parameters are magnitude M2, equivalent to the mean annual total strain energy release, and magnitude M3, analogous to the maximum strain energy which may be accumulated and released in a region. Empirical relation between M3 and M2 is obtained and the result shows that it has a worldwide validity. The quantity Dt, showing the time difference per year between the upper bound line (in the energy diagram) and the time since the last seismic activity (strain energy accumulation) is suggested here. An effort is made to forecast the approximate time of the next earthquake occurrence with magnitude less or equal to the maximum strain energy release. Finally, it clears that the Western Desert are a suitable region for establishing the site of radioactive waste repository

    The current water shortage in Egypt is 13.5 Billion cubic meter per year (BCM/yr) and is expected to continuously increase. Currently, this water shortage is compensated by drainage reuse which consequently deteriorates the water quality. Therefore, this research was commenced with the objective of assessing different scenarios for 2025 using the Water Evaluation and Planning (WEAP) model and by implementing different water sufficiency measures. Field data were assembled and analyzed, and different planning alternatives were proposed and tested in order to design three future scenarios. The findings indicated that water shortage in 2025 would be 26 BCM/yr in case of continuation of current policies. Planning alternatives were proposed to the irrigation canals, land irrigation timing, aquatic weeds in waterways and sugarcane areas in old agricultural lands. Other measures were suggested to pumping rates of deep groundwater, sprinkler and drip irrigation systems in new agricultural lands. Further measures were also suggested to automatic daily surveying for distribution leak and managing the pressure effectively in the domestic and industrial water distribution systems. Finally, extra measures for water supply were proposed including raising the permitted withdrawal limit from deep groundwater and the Nubian aquifer and developing the desalination resource. The proposed planning alternatives would completely eliminate the water shortage in 2025. PMID:27222745

    Full Text Available Dinoflagellates from Red Sea are hardly studied, in particular the benthic forms. Samples collected from shallow intertidal zone, Ain Sokhna, Egypt were microscopically examined. Three genera with seven species were recorded. The most frequently-encountered was Katodinium sp., a small mushroom-like with epitheca being consistently larger than hypotheca. Light micrographs revealed the presence of a nucleus in the hyposome and descending cingulum. Scanning electromicrographs (SEM confirmed this orientation and revealed the presence of apical pore system. Another species showed similarity to the mushroom-like morphology but with large conical episome and small hyposome. Heterotrophic, naked Gyrodinium cf dominans and Gyrodinium sp. were also observed where in the former, there were conspicuous longitudinal striations. A frequently-observed species had naked Gyrodinium-like morphology but with much smaller size. One photosynthetic species had a characteristic stigma similar to type B eyespot in “dinotoms” and episome being slightly larger than hyposome. Gymnodinium sp. with sulcus extending slightly in the episome but deeply to the end of hyposome was also recorded. This genus is reported to be mostly toxic and its presence should be monitored. Finally, this study presents some early records for benthic dinophytes from rather underexplored locality and raises alerts about genus with reported toxicity.

  18. nuclear emergency management system case study:- Egypt's second research reactor

    International Nuclear Information System (INIS)

    the response to a radiological accident is basically the same as the response to any accident involving hazardous material. provisions should be developed to identify potential radiological hazard and inform the public and emergency workers of the action they should take. radiological emergency plans provide an efficient and effective response operation that, should an emergency occur, will protect the health and safety of workers, responders, the public, and the environment . one of the most important aspects of managing a nuclear emergency is the ability to promptly and adequately estimate the consequences of an accident. because of the need for protective actions to be initiated promptly in order to be effective, nuclear accident assessment must make use of all information that is available to on-site and of - site organizations. the work done in this paper describes the overall organization, including its relationship to the overall structure, and responsibility of all internal organizational elements with emergency responsibilities, practical guidance and tools for accident assessment and a basic assessment capability needed in the event of a serious reactor accident.An emergency management intelligent system (EMIS) is developed to provide assistance in the situation of radiological accident. The EMIS can be applied to a broad spectrum of accidents at Egypt's second research reactor. Complete data analysis is given in case of loss of coolant accident (LOCA) including dose assessment for the public

    2012-05-01

    Full Text Available A total of 134 Egyptian liver flukes were collected from different definitive hosts (cattle, sheep, and buffaloes to identify them via the use of PCR-RFLP and sequence analysis of the first nuclear ribosomal internal transcribed spacer (ITS1. Specimens of F. hepatica from France, as well as F. gigantica from Cameroon were included in the study for comparison. PCR products of ITS1 were subjected for digestion by RsaI restriction enzyme and visualized on agarose gel. According to RFLP pattern, Egyptian flukes were allocated into two categories. The first was identical to that of French hepatica flukes to have a pattern of 360, 100, and 60 (bp band size, whereas the second resembled to that of Cameroonian gigantica worms to have a profile of 360, 170, and 60 bp in size. Results of RFLP analysis were confirmed by sequence analysis of representative ITS1 amplicons. No hybrid forms were detected in the present study. Taken together, this study concluded that both species of Fasciola are present in Egypt, whereas the hybrid form may be not very common.

    This cross-sectional study was carried to determine the prevalence of intestinal parasitic infections among mentally handicapped individuals in Alexandria, Egypt, in the period from December 2012 till November 2013. The study was conducted on 200 institutionalized and non-institutionalized mentally handicapped individuals. Fresh stool samples were subjected to different stains including; trichrome for detecting intestinal protozoa, modified acid fast stain for intestinal coccidia and quick hot gram chromotrope stain for Microsporidia. Also they were processed by Kato-Katz and formol ethyl acetate techniques for intestinal helminths. Additionally, blood samples were collected for measuring hemoglobin levels. Out of 200 mentally handicapped individuals, 87 (43.5%) were infected. The infection rates were 44.6% and 42.6% for non-institutionalized and institutionalized people, respectively. Regarding gender, 46.7% and 38.5% were reported for the males and females respectively. The most common parasites detected were: Cryptosporidium sp. (23.5%), microsporidia (15%), Giardia lamblia (8.5%), Dientamoeba fragilis (8%), Cyclospora cyatanensis (7.5%), Blastocystis hominis (6.5%), Entamoeba histolytica (5.5%) and Entamoeba coli (2.5%). Rates for Isospora belli and Enterobius vermicularis were estimated to be 1.5% for each, while lower rate was reported for Iodamoeba butschlii (1.0%). Prevalence of infections among mentally handicapped individuals are indications for several risk factors, including improper sanitary hygiene and illiteracy about personal hygiene. Therefore, frequent investigations, health care and medical intervention are needed. PMID:26878626

    Full Text Available Chronic mastitis is a prolonged inflammatory breast disease, and little is known about its etiology. We identified 85 cases and 112 controls from 5 hospitals in Morocco and Egypt. Cases were women with chronic mastitis (including periductal, lobular, granulomatous, lymphocytic, and duct ectasia with mastitis. Controls had benign breast disease, including fibroadenoma, benign phyllodes, and adenosis. Both groups were identified from histopathologically diagnosed patients from 2008 to 2011, frequency-matched on age. Patient interviews elicited demographic, reproductive, breastfeeding, and clinical histories. Cases had higher parity than controls (OR = 1.75, 1.62–1.90 and more reported history of contraception use (OR = 2.73, 2.07–3.61. Cases were less likely to report wearing a bra (OR = 0.56, 0.47–0.67 and less often used both breasts for breastfeeding (OR = 4.40, 3.39–5.72. Chronic mastitis cases were significantly less likely to be employed outside home (OR = 0.71, 0.60–0.84 and more likely to report mice in their households (OR = 1.63, 1.36–1.97. This is the largest case-control study reported to date on risk factors for chronic mastitis. Our study highlights distinct reproductive risk factors for the disease. Future studies should further explore these factors and the possible immunological and susceptibility predisposing conditions.

    Full Text Available Aim. To assess the knowledge and practice of PHC physicians toward the detection and management of hypertension (HTN and other CVD risk factors. Methods. A cross-sectional study of all primary health care physicians of the FHU of three rural districts of Egypt was conducted. Each physician was subjected to a prevalidated interview questionnaire on the WHO-CVD risk management package for low and medium resources, and a checklist of observation of daily practices. Results. Hypertension was a priority problem in about two-thirds (62.9% of physicians, yet only 19% have guidelines for HTN patients. Clinical history recording system for HNT was available for 50% of physicians. Levels of knowledge varied with regard to definition of HTN (61.3%, fair, procedures for BP measurement (43.5%, poor, indications for referral (43.5%, poor, patient counseling (61.3%, fair, patient treatment (59.8%, fair. Availability of clinical history recording system for HNT was a significant predictor for physician's level of knowledge (P=0.001. Overall level of practice was fair (68.5%. Conclusion. PHC physicians have unsatisfactory knowledge and practice on hypertension. There is a need of more continuing medical education. Local and international manuals, workshops, and seminars on how to make use of these guidelines would improve doctors' performance.

    Full Text Available Drought is the most damaging climate-related hazards due to the prolonged absence of precipitation. Therefore, understanding the drought dynamics is important for irrigation water management to mitigate the negative impacts on agriculture. In this study, Standardized Precipitation Index (SPI and Standardized Precipitation Evapotranspiration Index (SPEI were used as effective tools for tracking the changes of water status occurred at five agro-meteorological stations (Etay Al Baroud, Wadi El-Natrun, Al Boseli, Badr and Nubariyah within El-Beheira governorate, Egypt. In addition, the overall water risk for agro-meteorological stations was estimated using the Aqueduct-GIS tool. The results clarified that Badr agro-meteorological station is representing the highest of water deficit by 96.6%, whereas, Al Boseli agro-meteorological station is representing the lowest water deficit by 86.9%. However, The SPI over El-Beheira region often confined in the near normal class, while the SPEI showed a notable increase of drought (SPEI = 0 to -4 in last 10 years of the analyses. The results suggested that El-Beheira governorate is moving toward the drought in general and Wadi El-Natrun and Nubariyah are the most drought affected areas in the future.

    Food intake choice and amount might change with stress. However, this has not been examined among Egyptian students. We examined students' stress levels, its correlation with their consumption of a range of food groups, and adherence to dietary guidelines. A cross sectional survey (N = 2810 undergraduates at 11 faculties at Assiut University, Egypt) assessed two composite food intake pattern scores (one unhealthy: sweets, cakes, snacks; and a healthy one: fruits and vegetables), and two indicators of healthy eating (subjective importance of healthy eating; and dietary guideline adherence index). Multiple linear regression tested the associations of stress with two food intake pattern scores and two indicators of healthy eating, controlling for six potential confounders for the sample and separately for males and females. Higher perceived stress score was significantly associated with less frequent food intake of fruit and vegetables in males and females. The association was more pronounced among males than in females. No significant association was observed between the sweets cakes and snacks score and stress. Of the two indicators of healthy eating, the dietary guideline adherence index was not associated with stress, while the subjective judgment of healthy eating was consistently negatively associated with stress. Stress related decreased-eating was present. Recent studies suggest that stress could be associated with either decreased or increased eating depending on the study population, food group, and type of stressor. Further research is necessary to understand stress related over- and undereating.

  5. Trace metals distribution in environmental samples from lake Naser, Egypt

    International Nuclear Information System (INIS)

    Distribution of heavy metals and trace elements from anthropogenic as well as lithopogenic origin in sediment, soil and water samples from lake Naser has been investigated. The study reviles information on the characteristic lake-typical mean, value and areal pattern of the investigated variables. Soil and sediment samples were analyzed using instrumental neutron activation analysis (INAA), whereas water samples analysis were carried out using inductively coupled plasma-mass spectrometry (Icp-Ms). The distribution Cd, Pb and Cu within water column profile - at surface, 5 m, and 40 m depth-along the lake shows proportional relation between the concentration of most of the investigated elements and the depth. The average concentrations of Cd, Pb and Cu in water from the previously selected depths along the lake were (0.13, 0.16, 0.51 ng/ml), (26, 22, 41 ng/ml) and (7.8, 19, 99 ng/ml) respectively. The most elevated elemental concentration was found in Argin bottom sediment, while the lowest concentration was found in Toshki shore sediment. The study provides a preliminary base-line data essential for the investigated area that is pre-industrialized area and represents the location of one of the greatest agricultural projects to be performed in Egypt

  6. Serum organochlorine levels and history of lactation in Egypt

    International Nuclear Information System (INIS)

    We conducted a study in Egypt to assess the determinants of organochlorine serum levels among premenopausal women and the risk of premenopausal breast cancer for women with high organochlorine serum levels. We included 69 breast cancer patients and 53 controls consisting of visitors to the hospitals of the cancer patients. We found low levels of dichlorodiphenyldichloroethylene (DDE), total dichlorodiphenyltrichloroethane, and β-hexacholorhexane (β-HCH) in most subjects. Mean DDE levels were 12.7±20.3 ppb for cases and 16.6±30.1 ppb for controls (P=0.60); β-HCH levels were 2.1±3.8 ppb for patients and 2.1±3.9 ppb for controls (P=0.71). Interestingly, subjects with low levels had breast fed their children for an average period of 18 months. Women with no lactation history had much higher organochlorine levels than women who breast fed (P=0.002 for DDE). Younger age, older age at first childbirth, and shorter duration of breast feeding were significant predictors of higher levels of serum DDE levels. Younger age, older age at first childbirth, and higher body mass index were significant predictors of higher β-HCH levels. This study suggests that organochlorine serum levels in Egyptian women are quite low, but indicates an effect of breast feeding in eliminating organochlorines, which would imply exposure to children. Organochlorine serum level was not a risk factor of breast cancer in this population

  7. Does Gender Predict Medical Students’ Stress in Mansoura, Egypt?

    2008-08-01

    Full Text Available Background: Medical education is perceived as being stressful with negative effects on students’ mental health. However, few studies have addressed the influence of gender on stress in medical students.Aim: To compare male and female medical students in Egypt on sources of stress, perception of stress, anxiety, depression, physical symptomatology, and personality profile.Methods: Data were collected through an anonymous self-administered questionnaire covering socio-demographic data, stressors, perceived stress scale, physical wellbeing factors, the Hospital Anxiety and Depression scale as well as neuroticism and extraversion subscales of the Eysenck Personality Questionnaire.Results: Stressors were reported by 94.5% of the total sample with equal gender proportions. Univariate analysis indicated that female students scored higher than males on depression and neuroticism scales while male and female medical students were similar on level of perceived stress, number of stressors, clinical anxiety, physical well-being factors and the extraversion scale. Multivariate logistic regression revealed that the independent predictors of a high stress level were the presence of more than five stressors, clinical anxiety and depression, and increased scores on the global sickness index and on the extraversion and neuroticism sub-scales.Conclusion: Despite there being no significant difference in perceived stress according to gender, females were less likely to cite relationship problems with teachers and substance abuse as sources of stress. Moreover, females scored significantly higher than males on depression and neuroticism scales.

The phytoplankton composition and distribution infive ponds of increasing salinity were investigated in the solar saltern of Port Fouad.The phytoplankton community consisted of 42 species belonging to cyanobacteria(16, diatoms (12, dinoflagellates (11, Euglenophyceae (2 and Chlorophyceae (1.The number of species decreased significantly and rapidly with increasing salinity,varying between 33 species in the first pond (P1 and one species in the crystallizerpond (P5. Conversely, the total phytoplankton density, except that recordedin P1, increased significantly with rising salinity, fluctuating between 8.7 and56 × 105 individuals l-1 in P2 and P5 respectively. In spiteof the local variations in climate and nutrient availability, the phytoplankton composition, density and spatialvariations along the salinity gradient were, in many respects, very similar towhat has been observed in other solar saltworks. The pond with the lowest salinity(P1 - -1 was characterized by a significant diversity andblooming of diatoms and dinoflagellates. Intermediate salinity ponds (P2 andP3 with salinity ∼ 112-180 g l-1 exhibited a decline in bothspecies richness and density, but the stenohaline blue green algae (Synechocystis salina did flourish. The highly saline concentrating ponds andcrystallizers (P4 and P5 with salinity ∼ 223-340 g l-1 werecharacterized by few species, the disappearance of blue green algae and thethriving of the halotolerant green alga Dunaliella salina.

    Indoor radon has been recognized as one of the health hazards for mankind. Common building materials used for construction of houses, which are considered as one of the major sources of this gas in indoor environment, have been studied for exhalation rate of radon. Non-nuclear industries, such as coal fired power plants or fertilizer production facilities, generate large amounts of waste gypsum as by-products. Compared to other building materials waste gypsum from fertilizer production facilities (phosphogypsum) shows increased rates of radon exhalation. In the present, investigation solid state alpha track detectors, CR-39 plastic detectors, were used to measure the indoor radon concentration and the radon exhalation rates from some building materials used in Egypt. The indoor radon concentration and the radon exhalation rate ranges were found to be 24-55 Bq m(-3 )and 11-223 mBq m(-2) h(-1), respectively. The effective dose equivalent range for the indoor was found 0.6-1.4 mSv y(-1). The equilibrium factor between radon and its daughters increased with the increase of relative humidity.

    Learning about menstrual hygiene is a vital aspect of health education for adolescent girls. This study among 664 schoolgirls aged 14-18 in Mansoura, Egypt, asked about type of sanitary protection used, frequency of changing pads or cloths, means of disposal and bathing during menstruation. Girls were selected by cluster sampling technique in public secondary schools in urban and rural areas. Data were collected through an anonymous, self-administered, open-ended questionnaire during class time. The significant predictors of use of sanitary pads were availability of mass media at home, high and middle social class and urban residence. Use of sanitary pads may be increasing, but not among girls from rural and poor families, and other aspects of personal hygiene were generally found to be poor, such as not changing pads regularly or at night, and not bathing during menstruation. Lack of privacy was an important problem. Mass media were the main source of information about menstrual hygiene, followed by mothers, but a large majority of girls said they needed more information. Instruction in menstrual hygiene should be linked to an expanded programme of health education in schools. A supportive environment for menstrual hygiene has to be provided both at home and in school and sanitary pads made more affordable.

    Egypt has a high incidence of neural tube defects. Folic acid supplementation in the periconceptional period is known to lower the risk of such defects. This cross-sectional study aimed to measure the level of knowledge about periconceptional folic acid use among pregnant women attending for antenatal care at Ain Shams University Hospital, Cairo, Egypt in 2012. Questionnaires were filled through personal interviews with 660 pregnant women. Of the respondents, 62.4% had heard of folic acid and 39.2% knew about the role of folic acid supplementation in prevention of congenital anomalies. Knowledge about using folic acid before and in the first trimester of pregnancy was highest among university-educated women and those working in professional occupations. Only 18.8% of women reported taking folic acid, and 8.8% had used it before conception. Awareness campaigns are suggested to improve knowledge about folic acid among women in the childbearing period in Egypt.

  15. Feasibility of national and regional fuel cycle centres for Egypt's nuclear power programme

    International Nuclear Information System (INIS)

    This paper looks at the feasibility of setting up in Egypt national fuel cycle facilities covering reprocessing, enrichment, and fuel fabrication. It bases its conclusions on numerical calculations of the yellowcake, separative work, and spent fuel storage requirements of the Egyptian nuclear programme. These show that national fuel cycle facilities would not be economically advantageous, except for mining and conversion. The paper concludes, however, that the establishment of a multinational fuel cycle centre jointly with three or four countries with nuclear programmes similar to Egypt's could be economic. This would allow Egypt to make use of the energy content of uranium and plutonium in the spent fuel arising from its nuclear programme, and the paper gives calculations of the value of doing so

  16. Industrial Hazardous Waste Management In Egypt-the baseline study: An Updated review

    International Nuclear Information System (INIS)

    Increased industrialization over the past decades in Egypt has resulted in an increased and uncontrolled generation of industrial hazardous waste. This was not accompanied by any concerted efforts to control these wastes. Consequently, no system for handling or disposing of industrial wastes, in general, and industrial hazardous wastes, in specific, exists. In 1993, a baseline report was formulated to assess the overall problem of industrial hazardous waste management in Egypt. Consequently, recommendations for priority actions were identified and the main components of a national hazardous waste system under the provision of Law 4/ 1994 were presented. This paper provides an updated review of this report in light of the proposed technical, legal and institutional guidelines to help in the realization of such a needed waste management system in Egypt

    Full Text Available This paper approaches the democratization efforts of Egypt from a theoretical perspective. In this study it is argued that the liberal policies supported by US since 1980s have failed to democratize Egypt. The reforms and privatization attempts triggered the revolution but at the same time these reforms made the society vulnerable and democracy unsustainable. Liberal policies have opened up the system and expanded the rights to some extent but they have also widened the gap between the rich and the poor. As a result the middle class which is crucial for the survival of democracy has also been harmed through this process which have given rise to democratic instability in Egypt and resulted with a coup d'état.

    Full Text Available Plague is a zoonotic disease with a high mortality rate in humans. Unfortunately, it is still endemic in some parts of the world. Also, natural foci of the disease are still found in some countries. Thus, there may be a risk of global plague re-emergence. This work reviews plague biology, history of major outbreaks, and threats of disease re-emergence in Egypt. Based on the suspected presence of potential natural foci in the country, the global climate change, and the threat posed by some neighbouring countries disease re-emergence in Egypt should not be excluded. The country is in need for implementation of some preventive measures.

    Two Naegleria species were isolated and identified from various water sources in Lower and Upper Egypt. Identification was based on the morphology, nuclear division and the excystation and flagellation tests. The trophic, cystic and flagellate forms of N. gruberi are larger than those of N. fowleri and the cyst of the former species has one or more pores while that of the latter species has no pores and has an outer gelatinous layer. The size and the morphological characteristics of these two free-living amoebae from Egypt were in complete agreement with those previously described for amoebae of this same genus and species endemic to other geographical areas.

    This article examined sexual coercion within marriage in Egypt. Using cross-sectional survey data from a representative sample of married Egyptian women (N = 5,240), associations between forced intercourse and husband's control, as well as other relevant sociodemographic factors, were assessed through binary logistic regression models. The lifetime prevalence of forced intercourse was 6.2% and 4.6% during the past year, and husband's control was significantly associated with forced intercourse during a woman's lifetime (odds ratio = 3.5) and past year (odds ratio = 2.8). Interventions addressing gender patriarchy and men's control may decrease incidence of sexual coercion in Egypt and similar contexts.

    In Egypt rice cultivation in the river Nile Delta produces large amounts of rice straw as residue. Assuming that about 20% were used for other purposes about 2.8 Mt were left on the fields for burning within a period of 30 days to get quickly rid of leftover debris. The resulting emissions give a significant contribution to the air pollution called the ''Black Cloud''. A suitable technology for the use of rice straw is an important contribution to reduce air pollution and gives a significant contribution to use biomass as renewable energy in Egypt. Based on that fact rice straw was studied as possible feedstock for the BIOLIQ process. The BIOLIQ process which is under development at the Forschungszentrum Karlsruhe (Germany) is a two-step process for the production of chemicals, fuels or electricity from lignocellulosic biomass with high ash content. In the first step the biomass is liquefied by fast pyrolysis. The pyrolysis char and the pyrolysis liquid are mixed to form a slurry. In the second step the pumpable slurry is used to produce syngas in a pressurised entrained flow gasifier. After gas cleaning and conditioning the syngas is used for the production of fuels, chemicals and electricity as by-product. In this work rice straw is studied as a possible feedstock for fast pyrolysis and slurry preparation. First the Egyptian rice straw was chemically characterised. Ultimate analysis of rice straw showed an elemental composition of 47,8% C, 6,0 %H and 45,3% O, (daf). According to the elemental composition the HHV was calculated to be about 18,1 MJ/Kg (Dulong) up to 20,5 MJ/kg (Ebeling). Based on the experimental HHV 15,3 MJ/kg (rice straw dry, 18% ash) the HHV on a moisture and ash free basis was calculated to be 18,7 MJ/kg. According to the literature the lignin, hemicellulose and cellulose contents of rice straw were about 12%, 28% and 60%, respectively. The rice straw was chopped and sieved (2 mm sieve) and most of the straw dust was

    The concentration in black carbon (BC) has been monitored in the mega-city of Cairo (Egypt) during the autumn 2004 and spring 2005 intensive observation periods of the Cairo Aerosol Characterization Experiment (CACHE). As expected for a species released by human activities, hourly mean of this concentration is found to be large at all times. It is also significantly larger in autumn than in spring (9.9 {+-} 6.6 and 6.9 {+-} 4.8 {mu}gC/m{sup 3}, respectively) and quite variable at shorter (diurnal) time scales. Indeed, sharp concentration peaks larger than 25 {mu}gC/m{sup 3} are frequently detected during both observation periods. In order to apportion the roles played by emission intensity and meteorological conditions in the development of these peaks, a simple model is developed that allows derivation of the hourly mean BC emissions by the part of town located upwind of the measurement site. The analysis of the time dependence of these emissions indicates that traffic is by far the major source of BC in Cairo during daytime and this even in autumn when biomass burning takes place in the Nile delta. It is only between 03:00 and 05:00 in the night, at a time when traffic emissions are quite reduced, that the influence of this particular source on BC concentration can become significant. This study also indicates that BC emissions by motorized traffic remain important from the morning rush hour until late in the night. During the day, and particularly in spring, the dilution effect resulting from the development of the planetary boundary layer prevents BC concentrations from becoming very large. This is no longer the case just before sunrise and after sunset, when the combination of dense traffic and low boundary layer is responsible for the observed sharp increase in BC concentration.

    A survey of two-year studies (2001-2003) was carried out in two olive groves sited at two representative olive growing areas, namely Paradise Park (arid area) and Burg E1-Arab farm (semi-arid area) to monitor the frequency of endemic Trichogramma species on olive moth (Prays oleae) and jasmine moth (Palpita unionalis). The suspended host bait traps were found to be a more practical and effective tool for collecting Trichogramma wasps than the attached ones. Four naturally occurring Trichogramma species were collected for the first time in Egypt from the olive groves, where releases have never been conducted. T.bourarachae was collected exclusively from Burg El-Arab farm. It seems that this wasp species adapts well to the semi-arid area. Three species, namely T. cordubensis, T. nr.pretiosum and T. cacociae were isolated from Paradise Park farm. All of these wasps were also bred from naturally parasitized host eggs during favorable and even at unfavorable temperature conditions of June-August. However, these endemic species did not occur naturally in sufficient numbers to keep the pest populations from reaching damaging levels.The excessive usage of insecticides and the oophagous predators (e.g., ants and lacewing larvae) are some factors that affect the performance of Trichogramma wasps in olive farms.The presence of warm weather wasp strains suggests the existence of well-adapted wasp species or swains which may be appropriate candidates for the control of target pests in olive groves. Additional study is required to determine the best “habitat-specific” species/strains of Trichogramma for augmentative release of naturally occurring wasps and to incorporate them into integrated pest management programs. Efforts should be made to conserve these endemic species from oophagous predators, hot weather and insecticides.The olive and jasmine moth-larvae and pupae found under tree canopies were bred and emerged parasitoids were listed.

    The tropospheric delay is a serious error source for positioning using Global Navigation Satellite Systems (GNSS). Since the scientific applications of GNSS positioning such as crustal deformation studies and earthquakes prediction require high accuracy in positioning, analysis of tropospheric delay is necessary to improve GNSS positioning accuracy In this study data of ground based GNSS receivers are used to evaluate effect of the tropospheric delay in position determination accuracy. These data are also used to study the tropospheric delay characteristics. The GNSS data are for the year 2013, taken from 8 station from Egypt Permanent GNSS Network (EPGN) and 13 IGS stations. The GNSS data were processed using advanced GNSS software called Bernese V 5.0 (Dach et al., 2007). The data processing was performed by three different ways; using a tropospheric model, making estimation for the tropospheric zenith wet delay (ZWD) and ignoring the Troposphere totally. Different processing methods are used to illustrate how troposphere affect the coordinates accuracy. The ZWD daily, temporal and spatial variations are also studied here. The results show that the RMS of the coordinates is better in case of making estimation for the troposphere ZWD and bad in case of ignoring the troposphere. Also there is a correlation between the troposphere and the height component. The troposphere ZWD values have daily, temporal and spatial variation. Depending on time in the day, day in the year, geographic location of the station and how near it to water. The ZWD values also go upward from the start to the end of the year, also it shows good correlation with the water vapor content in the troposphere.

  16. Hydrologic factors controlling groundwater salinity in northwestern coastal zone, Egypt

    2014-10-01

    The aim of this article is to assess the main factors influencing salinity of groundwater in the coastal area between El Dabaa and Sidi Barani, Egypt. The types and ages of the main aquifers in this area are the fractured limestone of Middle Miocene, the calcareous sandstone of Pliocene and the Oolitic Limestone of Pleistocene age. The aquifers in the area are recharged by seasonal rainfall of the order of 150 mm/year. The relationship of groundwater salinity against the absolute water level, the well drilling depth, and the ability of aquifer to recharge has been discussed in the present work. The ability of aquifer to locally recharge by direct rainfall is a measure of the vertical permeability due to lithological and structural factors that control groundwater salinity in the investigated aquifers. On the other hand, the fracturing system as well as the attitude of the surface water divide has a prime role in changing both the mode of occurrence and the salinity of groundwater in the area. Directly to the west of Matrouh, where the coastal plain is the narrowest, and east of Barrani, where the coastal plain is the widest, are good examples of this concept, where the water salinity attains its maximum and minimum limits respectively. Accordingly, well drilling in the Miocene aquifer, in the area between El Negila and Barrani to get groundwater of salinities less than 5000 mg/l is recommended in this area, at flow rate less than 10m3/hr/well. In other words, one can expect that the brackish water is probably found where the surface water divide is far from the shore line, where the Wadi fill deposits dominate (Quaternary aquifer), acting as a possible water salinity by direct rainfall and runoff.

    This study is titled (Environmental Assessment of Rosetta Area,Mediterranean Sea Coast, Egypt). The environmental assessment can be defined here as the process of assessing the potential impacts (positive or negative) of the presence of certain influential on a particular ecosystem. Samples were collected from Abu Khashaba beach area, Rosetta on the Mediterranean Sea coast. Samples of the beach sediments, sea-water and the scattered shells in this coastal region were collected. Sediments in this region are characterized by its large content of heavy metals, which added to these sediments its black color. It is known that these black sands occurred along the Mediterranean Sea coast from Alexandria to Rafah. The advantage of these black sand deposits is their contents from multiple economic metals which have important industrial uses, such as magnetite, ilmenite, rutile, monazite, zircon, garnet and other important minerals. Ten sampling profiles spaced in-between by about 600 m distance, and extending into the land from the shoreline for about 50 m or less. Along each profile, three sediment samples were collected; the first sample from the surface at the beach line, the second sample from the end of the foreshore area at a depth of about 50 cm and the third sample was taken from the backshore area at a depth of about 1 m. Extending from each profile into the sea, marine-water samples were taken at a distance of about 3 m from the beach line, and from a depth of about 1 m below the sea surface. The shells samples were collected from the scattered shells on the beach. By examination of these samples a 15 different shells types were defined.

    In Egypt, malaria is still reported as sporadic cases or small outbreaks particularly in El Faiyum Governorate. This paper aimed to identify and to study the breeding and seasonal activities of anopheline larvae. Spot light surveys were carried out in five different ecological areas (Karoun Lake, El Fedemean, El Siliyien, Kom-Osheim and Sinouris) from September 1991 to August 1992. Three species of Anopheles larvae were encountered: A. (Cellia) pharoensis (43%), A. (Cellia) sergenti (29.8%) and A. (Cellia) multicolor (27.2%). Several type of breeding places were encountered for the three species. A. pharoensis preferred clear, shallow, stagnant water with thick growth of vegetations an shae especially in rice fields. A. sergenti preferred clean, shallow to deep stagnant or slow-moving water with vegetations especially in small water collections in grassy areas and under palm trees. A. multicolor preferred shallow, stagnant water, sometimes partially exposed to sunlight especially in seepage water. The breeding waters for the three species were alkaline. Seasonal study of the anopheline larvae were conducted in three villages: Abheit El Hagar, El Zawia El Khadra and Tersa, in Sinouris Center during the year 1993. A. pharoensis larvae were abundant in the three villages in June, July, August and September with a peak in June. No breeding was noticed in January and February. A. sergenti larvae were abundant from September to November in the three villages, the lowest density was recorded in January and July in Abheit, in April in El Zawia and in June in Tersa. No breeding in February in the three villages was noticed and also in March in Abheit and Tersa. A multicolor larvae were recorded in Abheit and Tersa. In Abheit, the highest density was recorded in November with no breeding in January, February, March and June while in Tersa, the highest density was recorded in October and November with no breeding in January, February, March, April, July and December.

This cross-sectional study was conducted from November 2014 through April 2015. The target population was children aged 6 to 18 years, recruited into 4 groups, garbage city, moderate-living standard area, urban and suburban schools, and workshops in the city of Cairo. Blood lead levels (BLLs) and hemoglobin (Hb) concentrations were measured. Also, potential local environmental sources were assessed for hazardous lead contamination. Analysis on 400 participants has been carried out. A total of 113 children had BLLs in the range 10 to 20 μg/dL. Smoking fathers, housing conditions, playing outdoors, and exposure to lead in residential areas were significantly correlated with high BLLs. The mean values of hemoglobin were inversely correlated with BLLs. Children involved in pottery workshops had the highest BLLs and the lowest Hb values with a mean of (43.3 μg/dL and 8.6 g/dL, respectively). The mean value of environmental lead in workshop areas exceeded the recommended levels. Also, those values measured in dust and paint samples of garbage city were significantly high. Moreover, the mean lead levels in the soil samples were significantly higher in urban schools (P = 0.03) than the suburban ones. Childhood lead poisoning accounts for a substantial burden in Egypt, which could be preventable. Development of national prevention programs including universal screening program should be designed to reduce incidence of lead toxicity among children. PMID:26945415
