    Attention in this discussion of Egypt is directed to the following: geography; the people; history; government and political conditions; the economy; defense; foreign relations; and relations between Egypt and the US. The population totaled 50.5 million in 1986 with an annual growth rate of 2.8%. The infant mortality rate is 102/1000 (1986), and life expectancy is 58.3 years. Located in the northeastern corner of Africa, Egypt has a land area of about 1 million square kilometers and is bounded by the Mediterranean Sea, Libya, Sudan, the Red Sea, the Gulf of Aqaba, and Israel. Egypt is the most populous country in the Arab world. Egyptians are a fairly homogenous people of Hamitic origin. Mediterranean and Arab influences appear in the north, and there is some mixing in the south with the Nubians of northern Sudan. Egypt has been a unified state for over 5000 years, and archeological evidence indicates that a developed Egyptian society has existed for considerably longer. The constitution of Egypt provides for a strong executive with authority vested in an elected president who can appoint 1 or more vice presidents, a prime minister, and a cabinet. Egypt's legislative body has 458 members -- 448 popularly elected and 10 appointed by the president. Power is concentrated in the hands of the president and the National Democratic Party's majority in the People's Assembly, but opposition parties organize, publish their views, and represent their followers at various levels in the political system. The process of gradual political liberalization begun by Sadat has continued under Mubarak. In fiscal year 1987 the gross domestic product (GDP) reached about US$30 billion. Agriculture and services each contribute about 1/3 of GDP; the remainder comes from industry, petroleum, mining, electricity, and construction. At this time, the Egyptian economy faces several challenges. In 1986 the government of Egypt initiated a major review of economic policy and initiated an economic

    We present first investigation of Pi 2 pulsations observed from MAGnetic Data Acquisition System (MAGDAS) at Fayum and Aswan stations (FYM and ASW) in Egypt. MAGDAS is an important component of the International Space Weather Initiative (ISWI). We carried out our analysis through a visual inspection comparing our events with burst in AE index during the period from November 2008 to October 2009. We used two different methods: (i) Fourier transformations and (ii) Wavelet power spectrum. Pi 2 events of H component, at FYM and ASW, have the same waveform and the same frequency, and some times the same amplitude, but in some cases FYM has relatively higher amplitude than ASW

    During regional heat flow studies a geothermal anomaly was discovered approximately 2 km from the Red Sea coast at Wadi Ghadir, in the Red Sea Hills of Eastern Egypt. A temperature gradient of 55 C/km was measured in a 150 m drillhole at this location, indicating a heat flow of approximately 175 mw/sqm, approximately four times the regional background heat flow for Egypt. Gravity and magnetic data were collected along Wadi Ghadir, and combined with offshore gravity data, to investigate the source of the thermal anomaly. Magnetic anomalies in the profile do not coincide with the thermal anomaly, but were observed to correlate with outcrops of basic rocks. Other regional heat flow and gravity data indicate that the transition from continental to oceanic type lithosphere occurs close to the Red Sea margin, and that the regional thermal anomaly is possibly related to the formation of the Red Sea.

  5. Remote sensing and geochemical investigations of selected surface processes in Egypt and Missouri

    This thesis consists of three studies of surface processes on Earth: 1. Age and isotopic constraints of pluvial episodes in the Western Desert of Egypt. North Africa has undergone drastic climatic change over the past several hundred thousand years. Timing of humid intervals called pluvials was investigated by uranium- series disequilibrium dating of travertines from the Kurkur Oasis, Western Desert, Egypt. Stable oxygen isotopes of the travertines were used in equilibrium oxygen isotope fractionation calculations indicating the Kurkur travertines have δ18O values similar to ancient Western Desert groundwaters (~[- ]11/perthous). The ages of the of the travertines correspond to times of monsoonal maxima, eustatic sea level high stands and interglacial maxima. Increased precipitation, recharge of Western Desert groundwaters, and resultant travertine deposition are interpreted to be consequences of Milankovitch cycle forcing, through enhanced Atlantic and Indian Ocean monsoons during periods of enhanced northern summer insolation. 2. Identification of soil moisture as an environmental risk factor for filariasis in Egypt. Bancroftian filariasis is a deforming illness transmitted by mosquitoes (Culex. pipiens) and caused by the parasite Wuchereria bancrofti (WHO technical report 821; Neva and Brown, 1994). Environmental variables, such as humidity, play an important role in the transmission cycle of filariasis. Landsat Thematic Mapper data were used to model the surface soil moisture conditions of the southern Nile Delta region of Egypt as a proxy for environmental humidity. Filariasis infection rates were found to be negligible for areas with low surface soil moisture availability (>20%). Variable infection rates were observed for regions with higher surface soil moisture content, possibly due to anthropogenic influences such as insect control and the use of anti- filarial drugs. 3.

    Our study aimed to identify the levels of various contaminants in both wet and dry commercial pet foods in Egypt. A total of 20 local and imported pet food products (3 samples each) were screened for heavy metals by atomic absorption spectroscopy, for mycotoxins by enzyme-linked immunosorbent assay, and for nitrate and nitrite levels by nitrate-nitrite spectrophotometry. Cat food, on average, had greater concentrations of the metals cadmium, chromium, lead, and tin than dog food. Of the investigated metals, only tin concentration exceeded the safe level compared with the standards of the National Research Council and the European Commission for the dog and cat. According to the guidelines of the Association of American Feed Control Officials for canned pet foods, the nitrate and nitrite contents of examined foods greatly exceeded the recommended level. No total aflatoxins were detected in the surveyed samples. None of the samples analyzed had levels above international limits established by the Food and Agriculture Organization (FAO) of the United Nations for ochratoxin, and only 1 sample exceeded the level for aflatoxin B1. Of the 20 samples analyzed for zearalenone, 4 samples had higher levels than the FAO maximum tolerable levels. These results indicate that pet foods marketed in Egypt, especially cat foods, occasionally contain contaminants that could result in adverse effects in pets.

    The weathering phenomena that have affected El-TUBA Minaret, one of the most important Islamic stone minarets in middle delta in Egypt; that has suffered from several factors of deterioration due to weathering phenomenon. The present investigations concern the weathering factors that may have affected the minaret via the following methods and techniques: a) Contact-free methods used to study the chemical and mineralogical composition of building materials before and after weathering effects such as SEM-EDX and XRD, b) Non-destructive methods to find out percentage of range of decay which has affected these materials as well as the deteriorating roles of the surrounding environment. This method has been used to make an anatomical scheme of these features especially to specific deteriorated parts by GIS and other digital imaging techniques. All results confirm that the degradation factors affecting the minaret building materials are essentially attributed to direct effects of weathering phenomena. These weathering phenomena arise from physical and chemical mechanisms which have lead to many deterioration forms on the following two scales: a) Macro scale of weathering phenomena (e.g. structural damages, crakes, loss of plumb and walls bulging), b) Micro scale of weathering phenomena (e.g. hydrated salts, bursting, flaking, coloration, scaling, skinning, exfoliation and soiling). Discussion on the management and rehabilitation of this monument is made, since it is one of the religious shrines in Egypt.

    Under increasing water scarcity, collective groundwater management is a global concern. This article presents an interdisciplinary analysis of this challenge drawing on a survey including 50 large and small farms and gardens in a village in an agricultural land reclamation area on the edge of the Western Desert of Egypt. Findings revealed that smallholders rely on a practice of shallow groundwater use, through which drainage water from adjacent irrigation areas is effectively recycled within the surface aquifer. Expanding agroindustrial activities in the surrounding area are socio-economically important, but by mining non-renewable water in the surrounding area, they set in motion a degradation process with social and ecological consequences for all users in the multi-layered aquifer system. Based on the findings of our investigation, we identify opportunities for local authorities to more systematically connect available environmental information sources and common pool resource management precedents, to counterbalance the degradation threat.

    New Borg El-Arab City, 60 km to the southwest of Alexandria City, is one of new industrial cities planned by the Egyptian Government through its program to transfer the population from the condensed Nile Delta to other places in Egypt. Because such a city includes airport, huge buildings, factories, and worker settlements, a careful geophysical study is planned to reveal the groundwater condition. This will help in defining the places of wells that are supposed to be drilled. Therefore more industrial and agricultural activities will be flourished. The present study embraces Vertical Electrical Soundings (VES'es) and Time Domain Electromagnetic sounding (TEM) to investigate the study area. The study aims to delineate the main subsurface conditions from the viewpoint of groundwater location, depth and water quality. Analysis and interpretation of the obtained results reveal that the subsurface consists of five geoelectrical layers with a gentle general slope toward the Mediterranean Sea. The third and the fourth layers in the succession are suggested to be the two water bearing formations of which the third layer is saturated with fresh water overlying saline water at the bottom of the fourth one. It is worth mentioning that the fresh water depth varies between 50 and 354 m under the ground surface. The thickness of the fresh water aquifer varies from 9.5 to 66 m; and the saline water depth varies between 116 and 384 m below the ground surface, the thickness of saline water aquifer differs from 34 to 90.5 m.

    The use of the pigment Egyptian blue is investigated on a corpus of fifteen mummy portraits and Roman-period paintings from Tebtunis, Egypt, housed in the Phoebe A. Hearst Museum of Anthropology at the University of California, Berkeley. Egyptian blue has a strong luminescence response in the near infrared that can be exploited to created wide-field images noninvasively showing the distribution of the pigment on a work of art. A growing body of publications in the last decade highlights the increasing use of this tool and its sensitive detection limits. However, the technique is not wavelength specific. Both excitation and emission occur in a broad range. Although Egyptian blue has a strong emission in the NIR, a myriad of other compounds may emit light in this spectral region when excited in the visible. The limited number of studies including complementary analysis to verify the presence of Egyptian blue does not allow its identification on the basis of NIR luminescence alone. Through the use of in situ X-ray fluorescence and X-ray diffraction, and scanning electron microscopy/energy-dispersive spectroscopy of cross sections, this paper confirms the identification of Egyptian blue by NIR luminescence in unexpected areas, i.e., those not blue in appearance.

    This study was conducted to investigate the ecological features of three geophytes namely Asparagus stipularis, Cyperus capitatus and Stipagrostis lanata which grow naturally in the Nile Delta coast of Egypt. C. capitatus and S. lanata are growing in non-saline sandy soils and can tolerate drought stress while, A. stipularis is growing in saline and non-saline sandy and calcareous clay soils and can tolerate drought and salt stress. Multivariate analysis of the vegetation of 100 sampled stands supporting growth of the three geophytic species in the study area led to the recognition of four vegetation groups namely, (A) Alhagi graecorum, (B) Cyperus capitatus, (C) Lycium schweinfurthii var. schweinfurthii-Asparagus stipularis and (D) Juncus acutus subsp. acutus. Vegetationally, the vegetation groups associated with the three species can be distinguished into two community types. The first one is psammophytic community comprising vegetation groups A and B that may represent the non-saline sand formations (flats, hummocks and dunes). The second one is halophytic community including vegetation groups C and D that may represent the saline sand flats and salt marsh habitat types, respectively. Sodium adsorption ratio, electrical conductivity, sodium cation, chlorides, silt and sand fractions, pH value, moisture content, bicarbonates and available phosphorus were the most effective soil factors that controlling the abundance and distribution of the plant communities associated with the investigated geophytes. This study showed the ecological features of the selected geophytes in terms of their habitats, associated plant communities and the most edaphic factors controlling their richness and distribution in the study area.

    An outbreak of foot-and-mouth disease (FMD) affecting cattle and water buffalo (Bubalus bubalis) occurred in Egypt during 2012/2013. The present study was undertaken to determine the current strains of the FMD virus (FMDV) and the prevalence of FMD among cattle and buffalo in Gharbia, Egypt. The diagnostic sensitivity of two RT-PCR assays for the detection of FMDV was evaluated. The results revealed that SAT2 was the causative agent. The percentage of infected of animals varied with the detection method, ranging from 62.5 % by the untranslated region (UTR) RT-PCR to 75.6 % by SAT2 RT-PCR. The overall prevalence and mortality rates were 100 and 21 %, respectively. The mortality was higher in buffalo (23.3 %) than it was in cattle (17 %). A partial sequence of SAT2 was identical (90-100 %) to Egyptian isolates and was close in similarity to sequences from Sudan and Libya. In conclusion, FMD in Egypt is caused by SAT2. No other serotypes were detected. The results of this study provided the valuable data regarding the epidemiology of SAT2 in cattle and water buffalo from Egypt, which strengthens the need to change the strategies of both control and prevention that help to prevent the spread of the disease.

    In this study, the future impact of Sea Level Rise (SLR) on the Nile Delta region in Egypt is assessed by evaluating the elevations of two freely available Digital Elevation Models (DEMs): the SRTM and the ASTER-GDEM-V2. The SLR is a significant worldwide dilemma that has been triggered by recent climatic changes. In Egypt, the Nile Delta is projected to face SLR of 1 m by the end of the 21th century. In order to provide a more accurate assessment of the future SLR impact on Nile Delta's land and population, this study corrected the DEM's elevations by using linear regression model with ground elevations from GPS survey. The information for the land cover types and future population numbers were derived from the Moderate Resolution Imaging Spectroradiometer (MODIS) land cover and the Gridded Population of the Worlds (GPWv3) datasets respectively. The DEM's vertical accuracies were assessed using GPS measurements and the uncertainty analysis revealed that the SRTM-DEM has positive bias of 2.5 m, while the ASTER-GDEM-V2 showed a positive bias of 0.8 m. The future inundated land cover areas and the affected population were illustrated based on two SLR scenarios of 0.5 m and 1 m. The SRTM DEM data indicated that 1 m SLR will affect about 3900 km(2) of cropland, 1280 km(2) of vegetation, 205 km(2) of wetland, 146 km(2) of urban areas and cause more than 6 million people to lose their houses. The overall vulnerability assessment using ASTER-GDEM-V2 indicated that the influence of SLR will be intense and confined along the coastal areas. For instance, the data indicated that 1 m SLR will inundate about 580 Km(2) (6%) of the total land cover areas and approximately 887 thousand people will be relocated. Accordingly, the uncertainty analysis of the DEM's elevations revealed that the ASTER-GDEM-V2 dataset product was considered the best to determine the future impact of SLR on the Nile Delta region.

    Two profiles have been sampled from the Nubia Sandstone at Aswan, south Western Desert: the 1st profile has been taken from Abu Aggag Formation and the 2nd one was from Sabaya Formation (23.25 °N, 32.75 °E). 136 oriented cores (from 9 sites) have been sampled. Abu Aggag Formation is of Late Cretaceous (Turonian) and Sabaya Formation is of early Cretaceous (Albian-Cenomanian). The studied rocks are subjected to rock magnetic measurements as well as demagnetization treatment. It has been found that hematite is the main magnetic mineral in both formations. Four profile sections from Abu Aggag Formation, yielded a magnetic component with D = 352.7°, I = 36.6° with α95 = 5.2° and the corresponding pole lies at Lat. = 82.8 °N and Long. = 283.1 °E. Five profile sections from Sabaya Formation, yielded a magnetic component with D = 348.6°, I = 33.3° with α95 = 5.8° and the corresponding pole lies at Lat. = 78.3 °N and Long. = 280.4 °E. The obtained paleopole for the two formations lies at Lat. = 80.5 °N and Long. = 281.7 °E. The obtaind magnetic components are considered primary and the corresponding paleopole reflects the age of Nubia Sandstone when compared with the previously obtained Cretaceous poles for Egypt.

    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.

    The site of investigation, oasis Kharga, is located at about 600 km south of Cairo, Egypt; Baris is about 90 km from Kharga also to south and towards more inside the desert. The work was aimed to investigate the rock mass stability at Baris and to estimate the water intake in the Oasis Kharga. A controlled source electromagnetic (CSEM) approach developed earlier by IGF UB RAS (Geophysical Federal Institute, Ural Branch of Russian Academy of Science) is applied to image the ranked deformation levels in the massive structure of the Baris. The wide profile system of observation has been used to monitor the three components of the alternating magnetic field along predefined measuring lines in the study area. Here we can show the first results that we shall continue during some cycles of monitoring. The second part of our work was linked with mapping the massif structure inside the oasis City, where only using our device we could construct the geoelectrical sections for 5 profiles and show the real structure of the water volume and its complicated structure up to 200 meters depth recording the values of real not apparent resistivity. The analytical treatments provided good information about the structure of the rock massive and its rank of degradation, the lateral distribution of the geotechnical heterogeneity, and finally a conclusive outcome about foundation stability. We can conclude that the general dynamic state close to the destruction level within the investigation areas is getting worse over the time; this is reflected in the crack's densities and positions, also on the changes in the lateral distribution of geoelectrical heterogeneity as an indicator of the saturation of the surface rock in the study area with water [1,2].

    Phosphorites in Egypt occur in the Eastern Desert, the Nile Valley and the Western Desert at Abu Tartur area and present in Duwi Formation as a part of the Middle Eastern to North African phosphogenic province of Late Cretaceous to Paleogene age (Campanian-Maastrichtian). The Maghrabi-Liffiya phosphorite sector is considered as the most important phosphorite deposits in the Abu Tartur area due to its large reserve thickness and high-grade of lower phosphorite bed beside high content of REE. Back scattered electron (BSE) images show framboidal pyrite filling the pores of the phosphatic grains, suggesting diagenetic reducing conditions during phosphorites formation. Electron Probe Micro Analyzer (EPMA) chemical mapping was conducted to examine the variation and distributions of selected elements (P, F, La, Fe, Yb, Si, Ce, W, Eu, S, Ca, Y and Er) within the shark teeth, coprolites and bone fragments. In the teeth W, S, Fe are concentrated along the axis of the teeth, the bone fragments show high concentration of W, Yb, Er and Eu, whereas coprolites are nearly homogenous in composition contains S, Er with some Si as micro-inclusions. Fluorapatite is considered as main phosphate mineral whereas pyrite occurs as pore-filling within the phosphatic grains and cement materials. Maghrabi-Liffiya samples show a wide range in the P 2O 5 content, between 19.8 wt.% and 29.8 wt.% with an average of 24.6 wt.% and shows low U content ranging from 15 ppm to 34 ppm with an average of 22 ppm. The total REE content in nine samples representing the Maghrabi-Liffiya ranges from 519 to 1139 ppm with an average of about 879 ppm. The calculation of LREE (La-Gd) show indeed a marked enrichment relative to the HREE (Tb-Lu) where LREE/HREE ratio attains 8.4 indicating a strong fractionation between the LREE and HREE. Chondrite-normalized REE patterns of the studied phosphorite samples show a negative Eu anomaly.

  1. Geophysical, hydrological, and archaeological investigation in the East Bank area of Luxor-southern Egypt

    The rise in level and increase in salinity of groundwater are causing accelerated deterioration of stone foundations of visible temples and monuments at Luxor, southern Egypt. Elevated groundwater is thought to cause a loss of cohesion and breakdown of the stone, while pressure developed within the stone upon salt crystallization and hydration may aid in the stone's disintegration. In addition to the rise in level and increase in salinity of groundwater, the expansion of urbanization and agriculture are jeopardizing buried monuments that have not been discovered and unearthed. The five main objectives were to: (1) characterize the subsurface geologic/hydrologic units; (2) identify sources responsible for the rise in level and increase in salinity of groundwater; (3) evaluate geometry and water quality of the shallow aquifer; (4) map the upper limit of capillary water and variations in soil moisture and (5) map yet undiscovered, buried monuments in the vicinity of the Karnak Temples complex. These five objectives were achieved based on the interpretations and results of the integrated geophysical and hydrologic data. (1) The shallow subsurface (<100m) was characterized into seven geoelectric (geologic/hydrologic) units. The second unit (silty clay) is thicker (12--28m) underneath the area of the Karnak and Luxor Temples, which may be a paleo-meander of the River Nile. (2) The source of the rise in groundwater level was determined to be due to the flow of groundwater from the central cultivated land towards the area of the temples. The groundwater salinity increased towards the temples, in the direction of groundwater flow, and may account for the increase in groundwater salinity beneath the temples. (3) The Quaternary aquifer in the study area was found to have a thickness and water quality that makes it usable for anthropogenic purposes. (4) The upper limit of capillary water was determined to be at depths of 0.0--2m. Salt accumulation on the monuments' foundations

    Hydrogeological investigations in arid regions are particularly important to support sustainable development. The study area, El Daba'a in northwestern Egypt, faces scarce water resources as a result of reported climate change that particularly affects the southern Mediterranean coast and increases stress on the local groundwater reserves. This change in climate affects the area in terms of drought, over-pumping and unregulated exploration of groundwater for irrigation purposes. The hydrogeological investigation is based on a multidisciplinary data-layer analysis that includes geomorphology, geology, slope, drainage lines, soil type, structural lineaments, subsurface data, stable isotopes, and chemical analyses. The study area contains Pleistocene and middle Miocene marine limestone aquifers. Based on lithology and microfacies analysis, the middle Miocene aquifer is subdivided into two water-bearing zones. The area is affected by sets of faults and anticline folds, and these structures are associated with fractures and joints that increase permeability and facilitate the recharge of groundwater. Stable isotope data indicate that groundwater of both the Pleistocene and middle Miocene aquifers is recharged by modern precipitation. The high salinity values observed in some groundwater wells that tap both aquifers could be attributed to leaching and dissolution processes of marine salts from the aquifers' marine limestone matrix. In addition, human activities can also contribute to an increase in groundwater salinity. A future water exploration strategy, based on the results from the multidisciplinary data-layer analysis, is proposed for the area. The derived scientific approach is transferable to other arid coastal areas with comparable conditions.

    Among the collections belonging to the National Museum of Lithuania at Vilnius, resides an ancient Egyptian coffin containing a mummified human body. The coffin and its occupant are believed to have belonged to the King of Poland and to have been located in his palace at Warsaw. At the turn of the last century, Egyptologists dated the coffin to the end of the 21st dynasty (1070 BC-945 BC), and described the item as coming from Thebes, belonging to Hori, priest of Amun-Ra. However, no investigation was ever carried out on the human body associated with the coffin. Within the framework of the Lithuanian Mummy Project, the preserved human remains underwent computed tomographic investigation in order to reconstruct the biological profile of the subject and to determine the embalming method employed. This led to the identification of a young adult male. Additionally, the mummy shroud was stylistically assessed in order to determine the mummy's chronology in Egyptian history. Interestingly, the body could be ascribed to the Roman period of Egypt (30 BC-395 AD) due to analogies with the burial shrouds of the Soter group. This indicates a reuse of the coffin at some point in history. PMID:26954562

    In this study we present the analysis of the human remains from tomb K93.12 in the Ancient Egyptian necropolis of Dra' Abu el-Naga, located opposite the modern city of Luxor in Upper Egypt on the western bank of the Nile. Archaeological findings indicate that the rock tomb was originally built in the early 18th dynasty. Remains of two tomb-temples of the 20th dynasty and the looted burial of the High Priest of Amun Amenhotep have been identified. After the New Kingdom the tomb was reused as a burial place until the 26th dynasty. The skeletal and mummified material of the different tomb areas underwent a detailed anthropological and paleopathological analysis. The human remains were mostly damaged and scattered due to extensive grave robberies. In total, 79 individuals could be partly reconstructed and investigated. The age and sex distribution revealed a male predominance and a high percentage of young children (< 6 years) and adults in the range of 20 to 40 years. The paleopathological analysis showed a high prevalence of stress markers such as cribra orbitalia in the younger individuals, and other pathological conditions such as dental diseases, degenerative diseases and a possible case of ankylosing spondylitis. Additionally, 13 mummies of an intrusive waste pit could be attributed to three different groups belonging to earlier time periods based on their style of mummification and materials used. The study revealed important information on the age and sex distribution and diseases of the individuals buried in tomb K93.12.

    In Egypt the population grew at a relatively slow pace prior to World War 2, but since 1974 the rate of growth has approximately doubled, primarily as a result of declining mortality conditions with the overall improvement in health conditions. The population totaled 46 million in 1983, giving Egypt one of the highest population densities in the world. The country is largely agricultural, dependent upon an intricate irrigation system of canals, drains, dams, and pumping stations. Nearly half of the labor force is engaged in farming or food processing, maintaining an agronomy with relatively high production, despite some inefficiencies. In the early 1970s the economy was aided by Sadat's "turn to the West." This caused an increased flow of foreign economic assistance. Despite the rising importance of petroleum products as an income earner, Egypt continues to have a large negative trade imbalance, in part caused by the necessity of importing food, scarce wood, and machinery for development. The predominantly Muslin population has had a history of high fertility and a traditional preference for large families. As the death rate declined in the postwar period, Egypt's high fertility caused a more rapid increase in population growth. If the present rate of growth were sustained, the population would double in size about every 25 years. The government has long been concerned about the effects of population and has, in recent years, adopted a vigorous national program to reduce fertility and slow growth. There is little question that some fertility decline has occurred in recent years, but it is difficult to determine exact values for recent levels and trends. In 1973 the government set a goal to reduce the crude birthrate by 1 point per year. Although that specific target was probably not reached, 1980 survey data indicate that about 40% of married women in urban areas and 12% in rural areas practice some form of contraception.

    GPR investigation has been conducted on Mut temple; to the south portion of Al-Karnak temple at the eastern bank of Luxor city. Within the survey, the GPR SIR system-10A has been used connected to 100/500 MHz antenna. The present work is oriented to allocate the buried Archaeological ruins at the site, and also to evaluate the archaeological significance of the artifacts in concern to the hydro-situation. The survey is composed of three data sets; the first set (A) includes three GPR profiles located inside the temple palisade at the western bank of the holy lake, the second set (B) includes four profiles distributed on the yard between Mute and Al Karnak temples, and the third set (C) includes three profiles oriented to study the EW Sphinx Avenue front of Mute temple. The measured GPR data has been processed and visualized in different ways to show the infra-content of the artifacts in the buried subsurface of the temple. Furthermore, intensive mutual work and discussion with the local inspectorate at Luxor about the results would lead to detect the zones of possible findings and, as much as possible, to define their identities. A series of sectional GPR records, time slices, maps, and 3D graphs are introduced to represent the remains of Mut temple and its infrastructure.

    An integrated geological, hydrochemical, and geoelectrical investigation of shallow groundwater occurrence in Burg El-Arab area, northwestern coastal zone of Egypt is carried out. Groundwater of oolitic limestone and clastic aquifers is the principal source of water supply for agriculture in the area. The purpose of this study is to describe the hydrogeologic characteristics of aquifers and to provide a general evaluation of the chemical quality of water in aquifers. Chemical analysis was used to evaluate the chemical characteristics of groundwater and assessment of water quality. Electrical soundings were employed to delineate different water bearing formations and the configuration of the interface between them. Thirty-four water samples were collected and chemically analyzed from the two main aquifers in the area. Groundwaters of oolitic limestone aquifer are dominated by NaCl and have average TDS of approximately 2830 mg/l. Groundwater samples from clastic aquifer are slightly weakly mineralized (TDS approximately 2700 mg/l) and dominated by CaSO4. The hydrochemical data indicate that the groundwater is of meteoric origin. The variation in the chemistry of water is thought to be related to the weathering of minerals of the water-bearing sediments, mixing with marine water, and leaching of fertilizers in the newly reclaimed areas. Groundwater of the area can be used for irrigation under special circumstances management as the sodium hazard is medium while the salinity hazard ranges from high to very high. Thirty-four profiles of vertical electrical soundings (VESs) were obtained in Burg El-Arab area to examine the variations of subsurface geology and associated groundwater chemistry. Resistivity and thickness of aquifers, resistivity of the unsaturated zone and depth to the confining bed have been delineated from the interpretation of electrical sounding data. The range of electrical resistivity values have been assigned to different layers by calibrating

    The dune field intersected by the Israel-Egypt borderline has attracted many remote sensing studies over the years because it exhibits unique optical phenomena in several domains, from the visual to the thermal infrared. These phenomena are the result of land-use policies implemented by the two countries, which have differing effects on the two ecosystems. This study explores the surface properties that affect radar backscatter, namely the surface roughness and dielectric properties, in order to determine the cause for the variation across the border. The backscatter contrast was demonstrated for SIR-C, the first synthetic aperture radar (SAR) sensor to capture this phenomenon, as well as ASAR imagery that coincides with complementary ground observations. These field observations along the border, together with an aerial image from the same year as the SIR-C acquisition were used to analyze differences in vegetation patterns that can affect the surface roughness. The dielectric permittivity of two kinds of topsoil (sand, biocrust) was measured in the field and in the laboratory. The results suggest that the vegetation structure and spatial distribution differ between the two sides of the border in a manner that is consistent with the radar observations. The dielectric permittivity of sand and biocrust was found to be similar, although they are not constant across the radar spectral region (50 MHz-20 GHz). These findings support the hypothesis that changes to the vegetation, as a consequence of the different land-use practices in Israel and Egypt, are the cause for the radar backscatter contrast across the border.

    The Temple of Kom Ombo is a huge ancient Egyptian temple in Upper Egypt. It was built by Ptolemy VI Philometor (180-145 BC) and added to by subsequent Ptolemys. The structure of the temple is built of local sandstone attributed to the Quseir Formation of "Nubian Sandstone" group at Gebel el-Silsila. Sandstone samples from Kom Ombo temple were taken to verify the source rock of the quarried material. Optical Polarizing Microscope (OPM) and Scanning Electron Microscope (SEM) were used to determine the microstructure and physical properties of the sandstone. X-Ray diffraction (XRD) was carried out for the Sandstone samples to identify its mineralogical composition. The sandstone samples were treated with six polymeric products to determine changes in their physical and mechanical properties after penetration, consolidation of polymers within them. This sandstone is composed mainly of three quartz arenite microfacies (feldspathic, sublithic and calcareous) that are interpreted to have been deposited in fluvial to fluvial-marine environment. Silane polymers is showing a good penetration and filling pores between grains and recommended for treatment and conservation of the sandstone. Acrylic polymer shows random penetration of polymer and formation of a film of polymer on the surface of sandstone. Silo11 gave the best result in consolidation of sandstone samples then primal AC33. Wacker BS29 gave the best result in isolating process of sandstone samples, then wacker BS 290.

    A study was carried out to establish the prevalence of subclinical mastitis (SCM) in smallholder dairy farms in Ismailia, Egypt. A total of 340 milking cows and buffaloes were sampled from 60 farms, and 50 nasal swabs were collected from consenting farm workers. Milk samples were subjected to California mastitis test (CMT) and the positive samples were examined by bacterial culture and PCR to identify etiological agents. Based on CMT, the prevalence of SCM was 71.6 % in cattle and 43.5 % in buffaloes while the prevalence was 25.2 % at cow-quarter level and 21.7 % at buffaloes-quarter level. Bacteriological analysis showed that the most frequently identified bacteria were Staphylococcus (S.) aureus (38.3 %) and Streptococcus (Str.) agalactiae (20 %). The diagnostic sensitivity of PCR compared to bacterial culture was superior with S. aureus and Str. agalactiae detection being 41 and 22.6 %, respectively. Furthermore, methicillin-resistant S. aureus (MRSA) strains occurred in 52.2 and 45 % of isolates of animals and workers, respectively. Subclinical mastitis due to S. aureus and Str. agalactiae is endemic in smallholder dairy herds in Ismailia. The occurrence of MRSA in animals and workers highlights a need for wide epidemiological studies of MRSA and adopting control strategies. PMID:25374070

    Mineralogical, geochemical and fluid inclusion studies reveal two favorable environments for the localisation of beryl mineralisations in the Precambrian rocks of Egypt: (1) emerald-schist; and (2) beryl-specialised granitoid associations. Emerald occurs within the mica schists and is typically confined to the Nugrus major shear zone. However, beryl associated with granitoids occurs in pegmatite veins, greisen bodies, and cassiterite quartz veins cutting the granites and the exocontacts of the volcanosedimentary country rocks. Compositionally, emerald is of octahedral type and its cell edge is lengthened along the a-axis, while beryl associated with granitoids is normal in composition and structural constants. Emerald is thought to be formed as the result of epitactic nucleation of Be, Al and alkali-rich solutions on the mica of the schist country rocks. Fluid inclusion studies show that the solutions are saline (8-22 wt% NaCl equiv.) and the reactions proceeded in the temperature range 260-382°C. On the other hand, aqueous inclusions in beryl associated with granitoids show the following sequence of formation with decreasing temperatures and salinities: beryl pegmatite (320-480°C and 7-16 wt% NaCl equiv.)→greisen bodies (190-400°C and 4-7 wt% NaCl equiv.)→cassiterite-quartz veins (190-380°C and 2-4 wt% NaCk equiv.). This study suggests that factors such as the chemistry of the Be-bearing fluids (rather than that of the bulk host schists) and syn-tectonic intrusions of leucogranites and pegmatites (Bederiving sources) along major ductile shear zones are the important factors controlling emerald formation. However, the endogreisens and exogreisens are the most important targets characterising the metasomatically- and magmatically-specialised, Be-granitoids, respectively. The aqueous inclusions examined in greisen beryls of metasomatised granites show a shorter range of homogenisation temperatures (260-390°C) and salinities(4.8-7 wt% NaCl equiv.) as compared

Ancient Egyptians built colossal temples and magnificent tombs to honor their gods and religious leaders. Their hieroglyphic language, system of organization, and recording of events give contemporary researchers insights into their daily activities. Based on the record left by their art, the ancient Egyptians documented the presence of dwarfs in almost every facet of life. Due to the hot dry climate and natural and artificial mummification, Egypt is a major source of information on achondroplasia in the old world. The remains of dwarfs are abundant and include complete and partial skeletons. Dwarfs were employed as personal attendants, animal tenders, jewelers, and entertainers. Several high-ranking dwarfs especially from the Old Kingdom (2700-2190 BCE) achieved important status and had lavish burial places close to the pyramids. Their costly tombs in the royal cemeteries and the inscriptions on their statutes indicate their high-ranking position in Egyptian society and their close relation to the king. Some of them were Seneb, Pereniankh, Khnumhotpe, and Djeder. There were at least two dwarf gods, Ptah and Bes. The god Ptah was associated with regeneration and rejuvenation. The god Bes was a protector of sexuality, childbirth, women, and children. He was a favored deity particularly during the Greco-Roman period. His temple was recently excavated in the Baharia oasis in the middle of Egypt. The burial sites and artistic sources provide glimpses of the positions of dwarfs in daily life in ancient Egypt. Dwarfs were accepted in ancient Egypt; their recorded daily activities suggest assimilation into daily life, and their disorder was not shown as a physical handicap.

    The isotopic composition of lead in Red Sea chloride brine containing 0.5 ppm Pb is found to be similar to that of some Cenozoic ore leads such as galena at Rabigh in Saudi Arabia that may have formed during mineralization accompanying Tertiary rifting. Bir Ranga galena in Miocene sediments from United Arab Republic (Egypt) is also isotopically similar to lead in Red Sea brine. The chlorine brine must be considered a possible mineralizing fluid. Lead isotopes show promise for use in mineral prospect evaluation in that galena from Samrah is isotopically similar to that from Mahd adh Dhahab, which has been the only ore producer in Saudi Arabia since 1945. Drilling at Samrah does indicate a possible economic mineralization. The lead isotope data coupled with available geologic knowledge and geochronometry are used to tentatively divide the ore prospects of the Kingdom of Saudi Arabia into relative categories of mineralization age. Two Mesozoic and Cenozoic mineralizations are distinguished on the basis of a 207Pb/204Pb difference; an early Paleozoic mineralization grouping is outlined; and a late Precambrian mineralization period is suggested. ?? 1967.

  9. Egypt at the crossroads.

    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

    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

  19. Solar Energy for Rural Egypt

    NASA Astrophysics Data System (ADS)

    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.

    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.

  1. The Regional Environmental Impacts of Atmospheric Aerosols over Egypt

    Zakey, Ashraf; Ibrahim, Alaa

    2015-04-01

    Identifying the origin (natural versus anthropogenic) and the dynamics of aerosols over Egypt at varying temporal and spatial scales provide valuable knowledge on the regional climate impacts of aerosols and their ultimate connections to the Earth's regional climate system at the MENA region. At regional scale, Egypt is exposed to air pollution with levels exceeding typical air-quality standards. This is particularly true for the Nile Delta region, being at the crossroads of different aerosol species originating from local urban-industrial and biomass-burning activities, regional dust sources, and European pollution from the north. The Environmental Climate Model (EnvClimA) is used to investigate both of the biogenic and anthropogenic aerosols over Egypt. The dominant natural aerosols over Egypt are due to the sand and dust storms, which frequently occur during the transitional seasons (spring and autumn). In winter, the maximum frequency reaches 2 to 3 per day in the north, which decreases gradually southward with a frequency of 0.5-1 per day. Monitoring one of the most basic aerosol parameters, the aerosol optical depth (AOD), is a main experimental and modeling task in aerosol studies. We used the aerosol optical depth to quantify the amount and variability of aerosol loading in the atmospheric column over a certain areas. The aerosols optical depth from the model is higher in spring season due to the impacts of dust activity over Egypt as results of the westerly wind, which carries more dust particles from the Libyan Desert. The model result shows that the mass load of fine aerosols has a longer life-time than the coarse aerosols. In autumn season, the modelled aerosol optical depth tends to increase due to the biomass burning in the delta of Egypt. Natural aerosol from the model tends to scatter the solar radiation while most of the anthropogenic aerosols tend to absorb the longwave solar radiation. The overall results indicate that the AOD is lowest in winter

  2. Epidemic of mesothelioma in Egypt.

    2005-07-01

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

  3. Skeletal dysplasia in ancient Egypt.

    The ancient Egyptian civilization lasted for over 3000 years and ended in 30 BCE. Many aspects of ancient Egyptian culture, including the existence of skeletal dysplasias, and in particular achondroplasia, are well known through the monuments and records that survived until modern times. The hot and dry climate in Egypt allowed for the preservation of bodies and skeletal anomalies. The oldest dwarf skeleton, the Badarian skeleton (4500 BCE), possibly represents an epiphyseal disorder. Among the remains of dwarfs with achondroplasia from ancient Egypt (2686-2190 BCE), exists a skeleton of a pregnant female, believed to have died during delivery with a baby's remains in situ. British museums have partial skeletons of dwarfs with achondroplasia, humeri probably affected with mucopolysaccharidoses, and a skeleton of a child with osteogenesis imperfecta. Skeletal dysplasia is also found among royal remains. The mummy of the pharaoh Siptah (1342-1197 BCE) shows a deformity of the left leg and foot. A mummified fetus, believed to be the daughter of king Tutankhamun, has scoliosis, spina bifida, and Sprengel deformity. In 2006 I reviewed the previously existing knowledge of dwarfism in ancient Egypt. The purpose of this second historical review is to add to that knowledge with an expanded contribution. The artistic documentation of people with skeletal dysplasia from ancient Egypt is plentiful including hundreds of amulets, statues, and drawing on tomb and temple walls. Examination of artistic reliefs provides a glance of the role of people with skeletal dysplasia and the societal attitudes toward them. Both artistic evidence and moral teachings in ancient Egypt reveal wide integration of individuals with disabilities into the society.

  4. Egypt's fundamentalists say condoms immoral.

    The first AIDS case in Egypt was reported almost 10 years ago, yet Egypt still does not have reliable statistics on the HIV/AIDS epidemic (officially, 513 HIV infections and 88 AIDS cases; more likely, 3000 and 10,000, respectively). HIV/AIDS bears a stigma. The government claims that every HIV-infected Egyptian acquired the infection through a blood transfusion while in the Gulf or through sexual intercourse in Europe. Cultural, social, and religious norms that discourage promiscuity may explain the low HIV/AIDS rate but these same taboos put women at risk by making it difficult for them to protect themselves. Islamic fundamentalist women reinforce the Islamic principle of forbidding sex education. They consider AIDS a plague of immoral Western society. They refuse to accept the fact that many men do not practice safer sex. These women consider condoms immoral. They think God will curse women who refuse to have sexual intercourse at their husbands' bidding. Many nongovernmental organizations consider an intensive education program as the only means to avert disaster. Egypt has yet to implement its model AIDS program. All hospitals in Cairo and some hospitals in rural areas have equipment to test for HIV. Surveillance systems have been limited to high risk groups. In Egypt, it is mandatory to test foreigners for HIV. Prisoners, prostitutes, homosexuals, and blood donors are tested randomly without their consent. Positive results are often reported to authorities before the persons learn their HIV status. A campaign for widespread sex education is the only action recommended so far. It includes a mass media component and community meetings and conferences. An Egyptian physician has found an anti-viral drug that stimulates the immune system, but his work does not receive much coverage outside Egypt. Egyptians need to tackle their cultural taboos about discussion of sex to curb the HIV/AIDS epidemic.

    The geoelectric survey includes 93 Vertical Electric Soundings (VES) and 26 TEM stations were conducted to delineate the subsurface structures and hydrogeological regime of El-Nubariya-Wadi El-Natrun area. The VESes AB/2 was varying from 1 up to 700 m in successive steps, while TEM stations were measured using coincident loop of 50 m side length. The interpretation of the geoelectrical data shows that the depth to the main aquifer ranges from 6 m at the northern part near the Nubariya city to about 90 m at the southern parts where it increases to the south and southeast directions. Generally the aquifer system in the area can be divided into Pleistocene and Pliocene aquifers. The Pleistocene aquifer is the shallower aquifer in the area and it consists almost of gravelly to clayey sand deposits. The Pliocene aquifer is the main aquifer where it is composed of sand to gravelly sand deposits. Depending on the results of the geoelectric prospecting represented by the true resistivity map, we can infer the quality of the groundwater. A brackish groundwater can be found at the northern and northeastern parts of the study area at shallow depths whereas relatively fresh water can be detected at the southern and southeastern parts around Wadi El Natrun city at deep depths. The area under consideration is affected by a group of normal faults that divided the investigated area into five main divisions, northern, eastern, western, southern and central divisions. The inferred faults from the geoelectric sections are traced and collected to construct a structure map. It is worth to mention that Wadi El Natrun and its lakes are structurally controlled by faulting systems trending NW direction.

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

  7. Clitoridectomy: female circumcision in Egypt.

    PubMed

    Hansen, H H

    Female circumcision, or clitoridectomy, has been mentioned in ancient writings from many parts of the world. There are 4 different degrees of total or partial clitoridectomy involving removal of different parts of the female genitalia. The most radical, Sudanese or Pharonic circumcision, is not now practiced in very many areas. The procedure is generally performed 1-2 years preceding puberty. Therefore, it cannot really be considered a rite of passage. Complications following the procedure are mentioned. The are 4 reasons for having the procedure performed: 1) religious; 2) aesthetic; 3) for prevention of undesirable sexual stimulation; and 4) tradition. In Egypt, the 4th most radical type of clitoridectomy is not practiced. The other 3 types are practiced by both Muslims and Christian Copts. During a stay in Egypt during 1966-67, the author had a chance to observe the incidence of the procedure among all classes of Egyptian women.

    Ophthalmology was one of the most important specialties in Egyptian medicine, and more specialists are known in this field than in any other. This specialization seems, however, to have been of a purely noninvasive nature. Even though it has been claimed that cataract surgery was performed in pharaonic Egypt, careful analysis of the sources does not support the claim. No example of cataract surgery or of any other invasive ophthalmologic procedure can be found in the original sources.

    Background — Ancient Egypt might be considered the cradle of medicine. The modern literature is, however, sometimes rather too enthusiastic regarding the procedures that are attributed an Egyptian origin. I briefly present and analyze the claims regarding orthopedic surgery in Egypt, what was actually done by the Egyptians, and what may have been incorrectly ascribed to them. Methods — I reviewed the original sources and also the modern literature regarding surgery in ancient Egypt, concentrating especially on orthopedic surgery. Results — As is well known, both literary sources and the archaeological/osteological material bear witness to treatment of various fractures. The Egyptian painting, often claimed to depict the reduction of a dislocated shoulder according to Kocher’s method, is, however, open to interpretation. Therapeutic amputations are never depicted or mentioned in the literary sources, while the specimens suggested to demonstrate such amputations are not convincing. Interpretation — The ancient Egyptians certainly treated fractures of various kinds, and with varying degrees of success. Concerning the reductions of dislocated joints and therapeutic amputations, there is no clear evidence for the existence of such procedures. It would, however, be surprising if dislocations were not treated, even though they have not left traces in the surviving sources. Concerning amputations, the general level of Egyptian surgery makes it unlikely that limb amputations were done, even if they may possibly have been performed under extraordinary circumstances.

    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.

    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.

    We report on the detection in southern Egypt of an impact crater 45 meters in diameter with a pristine rayed structure. Such pristine structures are typically observed on atmosphereless rocky or icy planetary bodies in the solar system. This feature and the association with an iron meteorite impactor and shock metamorphism provides a unique picture of small-scale hypervelocity impacts on Earth's crust. Contrary to current geophysical models, ground data indicate that iron meteorites with masses of the order of tens of tons can penetrate the atmosphere without substantial fragmentation.

    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.

  18. Dental surgery in ancient Egypt.

    Many different surgical procedures have over the years been attributed to the ancient Egyptians. This is also true regarding the field of dental surgery. The existence of dentists in ancient Egypt is documented and several recipes exist concerning dental conditions. However, no indications of dental surgery are found in the medical papyri or in the visual arts. Regarding the osteological material/mummies, the possible indications of dental surgery are few and weak. There is not a single example of a clear tooth extraction, nor of a filling or of an artificial tooth. The suggested examples of evacuation of apical abscesses can be more readily explained as outflow sinuses. Regarding the suggested bridges, these are constituted of one find likely dating to the Old Kingdom, and one possibly, but perhaps more likely, dating to the Ptolemaic era. Both seem to be too weak to have served any possible practical purpose in a living patient, and the most likely explanation would be to consider them as a restoration performed during the mummification process. Thus, while a form of dentistry did certainly exist in ancient Egypt, there is today no evidence of dental surgery.

  19. Antigenic analysis of highly pathogenic avian influenza virus H5N1 sublineages co-circulating in Egypt.

    Highly pathogenic avian influenza virus H5N1 has spread across Eurasia and Africa, and outbreaks are now endemic in several countries, including Indonesia, Vietnam and Egypt. Continuous circulation of H5N1 virus in Egypt, from a single infected source, has led to significant genetic diversification with phylogenetically separable sublineages, providing an opportunity to study the impact of genetic evolution on viral phenotypic variation. In this study, we analysed the phylogeny of H5 haemagglutinin (HA) genes in influenza viruses isolated in Egypt from 2006 to 2011 and investigated the effect of conserved amino acid mutations in the HA genes in each of the sublineages on their antigenicity. The analysis showed that viruses in at least four sublineages still persisted in poultry in Egypt as of 2011. Using reverse genetics to generate HA-reassortment viruses with specific HA mutations, we found antigenic drift in the HA in two influenza virus sublineages, compared with the other currently co-circulating influenza virus sublineages in Egypt. Moreover, the two sublineages with significant antigenic drift were antigenically distinguishable. Our findings suggested that phylogenetically divergent H5N1 viruses, which were not antigenically cross-reactive, were co-circulating in Egypt, indicating that there was a problem in using a single influenza virus strain as seed virus to produce influenza virus vaccine in Egypt and providing data for designing more efficacious control strategies in H5N1-endemic areas.

  20. Hazard estimation deduced from GPS and seismic data of Egypt

    Sayed Mohamed, Abdel-Monem

    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 GPS 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.

  1. Entropy of Egypt's virtual water trade gravity field

    2016-04-01

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

    ABSTRACT 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

    The purpose of this paper is to study the causes of localized terrain movements in Egypt. The motivation behind this research has been the vast progress in constructing huge engineering structures (dams, bridge,, tall buildings, etc.) as well as extending the urban activities in many new cities. These must be properly studied to ensure their safety versus their cost and other economic factors. In addition, the recent tendency is towards building nuclear power stations whose locations must be carefully investigated against the hazard and danger of inevitable atomic leakage, especially in the case of seismically active regions. Also the discovery of new oil wells and mines and the effects of future depletion require considerable attention from qualified investigators. The relative tectonic movements of North Africa and Southern Europe, the seismic activities around the Alexandria region, the presence of faults related to the region of the High Dam and its reservoir in Aswan, the erosion of the banks of the River Nile and its islands as well as coastal lines along the Mediterranean and the Red Sea, and the deformation and damage to large buildings in the Cairo area are examined here as a few examples of the implications of the earth's deformations within Egyptian territory. Strong recommendations are made concerning the necessity of studying and monitoring the terrain movements in the areas where new cities, large engineering constructions and power plants are planned to be erected.

    This oblique view, looking northeast from central Egypt, shows great expanses of the sand covered and rocky Western Desert in the foreground (bottom). The dark patches bottom right are the Dakhla Oases on the south side of an escarpment. The northern half of Egypt's Nile appears here, from about the latitude of Luxor to the delta. Green colors indicate the small area of crops which feed Egypt's population of 55 million. The Nile Delta is partly obscured by a band of clouds, but can be discerned at the coast as a flattened triangle of green. The smaller triangle close by is the Falyum Basin, a depression irrigated by water from the Nile. The coast of the Mediterranean Sea appears left.

  11. Status of fertility control in Egypt.

    PubMed

    Hefnawi, F I

    1982-01-01

    The concern for fertility control is not alien to the cultural and religious heritage of Egypt. Historically, Egyptian interest in fertility dates to the Pharoahs. Contraceptive recipes written at least 15-18 centuries B.C. have been found. Romans may have borrowed some of the more effective methods from Egypt when it became part of the Roman Empire as evidenced by the decline in size of aristocratic Roman families at the beginning of the Christian era. Muslim conquerors of Egypt encouraged fertility control. In the 9th century differences of opinion about the legality of contraception appeared among the interpreters of Islamic law. Some methods found in the writings of Muslim doctors as al-Razi and Avicenna still survive in the folk medicine of Egypt. In modern times use of barrier methods of contraception were encouraged by family planning organizations in Egypt. The medical profession was not deeply involved since these methods did not require much medical assistance. In 1936 a religiouss verdict declared contraception to be a lawful act of Islam. National programs in family planning in the 1960's encouraged the use of the Lippes Loop IUD. The medical problem of blood loss associated with the IUD caused anxiety because of the high incidence of anemia in the female Egyptian population. There was also a cultural limitation on the wide use of the IUD. "Spotting" due to the IUD resulted in females being ritually unclean and therefore unfit to pray or observe the Islamic fast. The Pill, initially favored caused complications due to its effect on breast milk which is the universal source of nutrition for infants in Egypt. Replacement of the Pill by depo-provera injections during the post partum period of lactation is a practical solution. Permanent sterilization is limited to females and only performed when medically indicated. Abortion is illegal and permitted only as a therapeutic measure.

  12. Megaliths and Neolithic astronomy in southern Egypt

    The Sahara west of the Nile in southern Egypt was hyperarid and unoccupied during most of the Late Pleistocene epoch. About 11,000 years ago the summer monsoons of central Africa moved into Egypt, and temporary lakes or playas were formed. The Nabta Playa depression, which is one of the largest in southern Egypt, is a kidney-shaped basin of roughly 10km by 7km in area. We report the discovery of megalithic alignments and stone circles next to locations of Middle and Late Neolithic communities at Nabta, which suggest the early development of a complex society. The southward shift of the monsoons in the Late Neolithic age rendered the area once again hyperarid and uninhabitable some 4,800 radiocarbon years before the present (years BP). This well-determined date establishes that the ceremonial complex of Nabta, which has alignments to cardinal and solstitial directions, was a very early megalithic expression of ideology and astronomy. Five megalithic alignments within the playa deposits radiate outwards from megalithic structures, which may have been funerary structures. The organization of the megaliths suggests a symbolic geometry that integrated death, water, and the Sun. An exodus from the Nubian Desert at ~4,800 years BP may have stimulated social differentiation and cultural complexity in predynastic Upper Egypt.

    2014-01-01

    This review presents a comprehensive picture of the zoonotic parasitic diseases in Egypt, with particular reference to their relative prevalence among humans, animal reservoirs of infection, and sources of human infection. A review of the available literature indicates that many parasitic zoonoses are endemic in Egypt. Intestinal infections of parasitic zoonoses are widespread and are the leading cause of diarrhea, particularly among children and residents of rural areas. Some parasitic zoonoses are confined to specific geographic areas in Egypt, such as cutaneous leishmaniasis and zoonotic babesiosis in the Sinai. Other areas have a past history of a certain parasitic zoonoses, such as visceral leishmaniasis in the El-Agamy area in Alexandria. As a result of the implementation of control programs, a marked decrease in the prevalence of other zoonoses, such as schistosomiasis and fascioliasis has been observed. Animal reservoirs of parasitic zoonoses have been identified in Egypt, especially in rodents, stray dogs and cats, as well as vectors, typically mosquitoes and ticks, which constitute potential risks for disease transmission. Prevention and control programs against sources and reservoirs of zoonoses should be planned by public health and veterinary officers based on reliable information from systematic surveillance.

    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.

    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

    1988-08-01

    A regional synthesis is presented of the stratigraphy of Jurassic strata in Egypt north of 30/degree/N, based on the study of about 80 wells and outcrops from northeastern Egypt. Almost all fossil groups have been investigated for biostratigraphic control. Published work on ammonite faunas from Gebel el Maghara (north Sinai) is integrated with extensive original work on palynofloras (and, to a lesser extent, ostracod/foraminiferal faunas) recovered from marine rocks in the subsurface. The recovery of rich dinocyst assemblages enables the recognition of a ten-fold zonation scheme, largely within the Middle-Late Jurassic sedimentary package. The upper limit of this package is marked by the Cimmerian erosional event; strata younger than Oxfordian are rarely preserved. Only east of 30/degree/E is significant sedimentation known to have occurred immediately prior to the major early Bajocian transgressive event. Thereafter mean sea level rose steadily. The Lower Triassic-Lower Jurassic sedimentary package is poorly understood, largely the result of scanty and ambiguous stratigraphic evidence. However, regional correlations suggest that only very thin earliest Jurassic (Hettangian ) clastic deposition succeeded a sequence of Upper Triassic carbonates and evaporites (Wadi en Natrun Formation) in the north. Arising from these studies is a standard lithostratigraphical scheme. The upper sedimentary package, the Gebel el Maghara Group, comprises three formations (Masajid, Khatatba, and Inmar) and seven members; new units are defined and old units redefined.

    Over a number of years studies have been carried out in Egypt on the transport by migrating birds of ticks that may transmit pathogens of man and animals. In continuation of these investigations 11 036 birds migrating southwards through Egypt were examined for ticks during the fall of 1962. The 881 infested birds (comprising 24 species and sub-species represented by 10 612 individuals) yielded 1442 ticks. Tick-host relationships were similar to those of previous years except that in 1962 the prevalence of infestation was almost invariably much higher than the averages for 1959-61. Five species of birds were added to the previous list of 40 infested forms. Previously unrecorded tick species taken during 1962 were Ixodes redikorzevi (a species from Asia very occasionally found in rodent burrows in Egypt), the rare Haemaphysalis inermis, and Hyalomma a. anatolicum, H. anatolicum excavatum and H. dromedarii, which may have been carried from Asia or have attached themselves to the birds at the time of netting. During the spring of 1962, altogether 1774 birds migrating northwards through Egypt were also examined. The 56 tick-infested birds (comprising 13 species represented by 867 individuals) yielded 186 ticks. As in previous years, Hyalomma marginatum rufipes was the chief species (89.25%) parasitizing spring migrants. A single specimen of Amblyomma variegatum was taken on Anthus cervinus and 19 specimens of Ixodes?sp. nov. were collected from Sylvia c. communis and Motacilla a. alba. PMID:14163959

    The future safe development of nuclear energy and progressive increasing use of sealed sources in medicine, research, industry and other fields in Egypt depends on the safe and secure management of disused radioactive sealed sources. In the past years have determined the necessity to formulate and apply the integrated management program for radioactive sealed sources to assure harmless and ecological rational management of disused sealed sources in Egypt. The waste management system in Egypt comprises operational and regulatory capabilities. Both of these activities are performed under legislations. The Hot Laboratories and Waste Management Center HLWMC, is considered as a centralized radioactive waste management facility in Egypt by law 7/2010. (authors)

    The highly productive coastal Mediterranean fishery off the Nile River delta collapsed after the completion of the Aswan High Dam in 1965. But the fishery has been recovering dramatically since the mid-1980s, coincident with large increases in fertilizer application and sewage discharge in Egypt. We use stable isotopes of nitrogen (δ15N) to demonstrate that 60%–100% of the current fishery production may be from primary production stimulated by nutrients from fertilizer and sewage runoff. Although the establishment of the dam put Egypt in an ideal position to observe the impact of rapid increases in nutrient loading on coastal productivity in an extremely oligotrophic sea, the Egyptian situation is not unique. Such anthropogenically enhanced fisheries also may occur along the northern rim of the Mediterranean and offshore of some rapidly developing tropical countries, where nutrient concentrations in the coastal waters were previously very low.

    Environmental impact assessment (EIA) was formally introduced in Egypt in 1994. This short paper evaluates 'how well' the EIA process is working in practice in Egypt, by reviewing the quality of 45 environmental impact statements (EISs) produced between 2000 and 2007 for a variety of project types. The Lee and Colley review package was used to assess the quality of the selected EISs. About 69% of the EISs sampled were found to be of a satisfactory quality. An assessment of the performance of different elements of the EIA process indicates that descriptive tasks tend to be performed better than scientific tasks. The quality of core elements of EIA (e.g., impact prediction, significance evaluation, scoping and consideration of alternatives) appears to be particularly problematic. Variables that influence the quality of EISs are identified and a number of broad recommendations are made for improving the effectiveness of the EIA system.

    Egypt's High Aswan Dam on the Nile River at the first cataracts, Nile River, (24.0N, 33.0E) was completed in 1971 to provide cheap hydroelectric power and to regulate the historically uneven flow of the Nile River. The contrast between the largely base rock desert east of the Nile versus the sand covered desert west of the river and the ancient irrigated floodplain downstream from the damsite is clearly shown.

  7. Living donor liver transplantation in Egypt

    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

    Trends of winter surface air temperature anomalies, WSATA, are investigated using data obtained from 13 monitoring stations. The analysis is performed in two steps; one deals with separate stations independently and the other deals with stations' groups. Groups' anomalies are correlated to circulation indices showing negative correlation between temperature with North Atlantic Oscillations and positive one with Mediterranean Oscillation Index. Both power analysis and frequency distribution analysis are applied. The results show existence of Schwabe, Hale and Gleissberg cycles and declare that there are no critical thermal changes of climate in Egypt. It is concluded that the temperature changes during the past three decades are not only because of the human activity but the extraterrestrial impacts as well.

  20. The corrosive well waters of Egypt's western desert

    USGS Publications Warehouse

    Clarke, Frank Eldridge

    1979-01-01

    The discovery that ground waters of Egypt's Western Desert are highly corrosive is lost in antiquity. Inhabitants of the oases have been aware of the troublesome property for many decades and early investigators mention it in their reports concerning the area. Introduction of modern well-drilling techniques and replacements of native wood casing with steel during the 20th century increased corrosion problems and, in what is called the New Valley Project, led to an intense search for causes and corrective treatments. This revealed that extreme corrosiveness results from combined effects of relatively acidic waters with significant concentrations of destructive sulfide ion; unfavorable ratios of sulfate and chloride to less aggressive ions; mineral equilibria and electrode potential which hinder formation of protective films; relative high chemical reaction rates because of abnormal temperatures, and high surface velocities related to well design. There is general agreement among investigators that conventional corrosion control methods such as coating metal surfaces, chemical treatment of the water, and electrolytic protection with impressed current and sacrificial electrodes are ineffective or impracticable for wells in the Western Desert's New Valley. Thus, control must be sought through the use of materials more resistant to corrosion than plain carbon steel wherever well screens and casings are necessary. Of the alternatives considered, stainless steel appears to. be the most promising where high strength and long-term services are required and the alloy's relatively high cost is acceptable. Epoxy resin-bonded fiberglass and wood appear to be practicable, relatively inexpensive alternatives for installations which do. not exceed their strength limitations. Other materials such as high strength aluminum and Monel Metal have shown sufficient promise to. merit their consideration in particular locations and uses. The limited experience with pumping in these desert

    Field investigations of aggraded paleovalleys, which were identified in southern Egypt using SIR, are discussed. Acheulian artifacts were found in authigenic carbonate deposites along the edges of the paleovalleys. Uranium series dating of 25 carbonate samples shows that widespread carbonate deposition in the area occurred about 45, 141, and 212 thousand years ago. Analysis of the carbonate suggests that the deposition may be related to late Pleistocene humid climates that facilitated human settlement in the region.

  4. Women in Egypt: new roles and realities.

    1986-01-01

    This is an extensive background presentation on the recent changes in Egyptian society, followed by results of a survey of attitudes toward family planning and the role of women. There have been remarkable social changes in Egypt recently, accompanied by rapid growth of the densely packed population. Virtually all of Egypt's 50 million people live on the banks of the Nile, 12 million of them in Cairo. Family planning has been government policy since 1981; the IUD and the pill are commonly used; but sterilization and abortion are illegal except for certain medical indications. Family subsidies and many public services have been eliminated, and even the lower classes are feeling the pinch of high cost of living, to the extent of desiring to balance their family size with their income. The survey was conducted by 35 students of the American University in Cairo, targeting middle and upper class adults, middle and upper class students, and lower class workers and domestics. The subjects were selected to be known to the interviewers to increase reliability of the data. This design created bias in the results, a preponderance of urban, student, single, childless and upper class subjects relative to the general population. The most common trend in the survey results was a conservatism among men, the lower class or less educated, or the rural lower classes. For example most women wanted 2 children, while those with traditional views valued male children and questioned the rights of women to be educated, to work outside the home, and to use contraception. The survey found that few people knew much about Egypt's Personal Status Law of 1979, which specifies women's rights regarding divorce, alimony, child support, and male polygamy. Women faced with divorce, however, rapidly learn their rights. This study revealed a consensus toward egalitarian values, along with distinct discord between the classes and sexes, and conflict between modern development and traditional roles for

    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

    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.

    Rift Valley fever (RVF) has been recorded in man and in domestic animals in Egypt after a 12-year absence. Human infections were first noted in the Aswan Governorate in late May, 1993. Only cases of ocular disease, an infrequent and late manifestation, were reported. Of 41 cases, 35 were tested serologically and 27 (77%) had RVF virus-specific IgM antibodies. An estimated 600-1500 infections occurred in the region. Abortions in cattle and buffalo were seen concurrently and antibodies to RVFV were present in 39% of domestic livestock, presumably unvaccinated. RVFV was isolated from an aborted water buffalo fetus.

    This unmatched case-control study aimed to identify factors affecting default from therapy under the national programme of TB control in Alexandria, Egypt. Record reviews and structured interviews were made with 57 defaulters and 187 randomly selected controls. Univariate analysis showed 13 out of 54 factors, investigated were significantly associated with defaulting and, after stepwise logistic regression, 5 factors remained in the model: younger age (adjusted OR = 0.16), rural area of residence (OR = 12.9), long waiting times (OR = 5.81), poor physician-patient communication (OR = 3.06) and fear of information leakage (OR = 3.62). Reasons cited by defaulters included long distance to the clinic, unsuitable clinic times and long waiting times. The main factors associated with defaulting from the national programme of TB control in Alexandria, Egypt were service-related factors, which are amenable to improvement.

    Species delimitation of Psoroptes spp. and identity of the parasite in water buffaloes remain poorly defined. In this study, Psoroptes infestation on three water buffalo farms in Egypt was examined based on morphometric characteristics, especially the opisthosomal setae of adult male mites. Clinical investigations showed that 28% (196/700) of the sampled animals had mange infestation. Microscopic examinations of 80 skin scrapings indicated the occurrence of Psoroptes mites in 17 (21.3%) samples, Sarcoptes mites in 27 (33.7%) samples, and the concurrence of both in 36 (45.0%) samples. Morphologically, the Psoroptes parasite was identified as Psoroptes natalensis. DNA sequence analysis of the second internal transcribed spacer (ITS2) in 11 representative samples confirmed the diagnosis and suggested the presence of a distinct variety of Psoroptes natalensis in Egypt.

    Geriatric care is a new phenomenon in Egypt. This study investigates how Egyptian caregivers experience their work and how they conceive its meaning. A qualitative case study in a geriatric home in Upper Egypt was conducted using structured interviews with 10 staff members and content analysis according to Mayring. Performing care required learning to overcome initial experiences of fear, disgust, and sexual taboo. Care was perceived as a laborious repetition. Its ideal form was described as a reaction to a demand combined with kind patience and a family-like relationship. Christian and female values allowed coping with experienced problems and alleviated conflicts between traditional gender roles and care of male residents. Traditional values helped to adapt to the requirements of providing care. Sexual taboos may reduce willingness to provide care, but traditional values may encourage caregivers.

    The aim of this study is to evaluate the neuropsychological status in a cohort of children with early and continuously treated phenylketonuria in Assiut, Upper Egypt. The study was implemented in seventy-eight phenylketonuria (PKU) children. Only 34 patients met the inclusion criteria. Investigated patients were evaluated according to detailed history, neurological examination, Childhood Autism Rating Scale, full scale Intelligence Quotient, attention deficit hyperactivity disorder, electroencephalography and magnetic resonance imaging (MRI). This study concluded that the prognosis for early diagnosed children with PKU treated from the first weeks of life is generally good. However, they are at increased risk for neurological complications and behavioral problems. So, neonatal screening for PKU is highly recommended in Egypt, for early detection and management. In addition, neuropsychological and MRI assessments in PKU children should be done. PMID:25576444

    This research explores the question - how do practices in key justice institutions affect the incidence and success of prosecutions of torture perpetrators in Egypt? The research question is grounded in the theory that torture prosecutions are crucial to ending the practice of torture, and based on the judgment that the number of prosecutions of torture perpetrators in Egypt is very small compared to the widespread practice of torture. This research observes practices in three main justice institutions: the Department of Public Prosecutions, the Department of Forensic Medicine and the criminal courts. Based on international and local literature, but also on interviews conducted with lawyers, forensic doctors and human rights activists, the research observes the practices most common to the three institutions, while analyzing their impact on the incidence and success of prosecutions. The research finds that different practices, backed by Egyptian legislation, and endorsed by poor institutional capabilities, violate the international standards for investigations, and affect the incidence and outcome of prosecutions.

Clinical investigations showed that 28% (196/700) of the sampled animals had mange infestation. Microscopic examinations of 80 skin scrapings indicated the occurrence of Psoroptes mites in 17 (21.3%) samples, Sarcoptes mites in 27 (33.7%) samples, and the concurrence of both in 36 (45.0%) samples. Morphologically, the Psoroptes parasite was identified as Psoroptes natalensis. DNA sequence analysis of the second internal transcribed spacer (ITS2) in 11 representative samples confirmed the diagnosis and suggested the presence of a distinct variety of Psoroptes natalensis in Egypt.

    The aim of this study is to evaluate the neuropsychological status in a cohort of children with early and continuously treated phenylketonuria in Assiut, Upper Egypt. The study was implemented in seventy-eight phenylketonuria (PKU) children. Only 34 patients met the inclusion criteria. Investigated patients were evaluated according to detailed history, neurological examination, Childhood Autism Rating Scale, full scale Intelligence Quotient, attention deficit hyperactivity disorder, electroencephalography and magnetic resonance imaging (MRI). This study concluded that the prognosis for early diagnosed children with PKU treated from the first weeks of life is generally good. However, they are at increased risk for neurological complications and behavioral problems. So, neonatal screening for PKU is highly recommended in Egypt, for early detection and management. In addition, neuropsychological and MRI assessments in PKU children should be done.

    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

  18. Transnasal excerebration surgery in ancient Egypt.

    2012-04-01

    Ancient Egyptians were pioneers in many fields, including medicine and surgery. Our modern knowledge of anatomy, pathology, and surgical techniques stems from discoveries and observations made by Egyptian physicians and embalmers. In the realm of neurosurgery, ancient Egyptians were the first to elucidate cerebral and cranial anatomy, the first to describe evidence for the role of the spinal cord in the transmission of information from the brain to the extremities, and the first to invent surgical techniques such as trepanning and stitching. In addition, the transnasal approach to skull base and intracranial structures was first devised by Egyptian embalmers to excerebrate the cranial vault during mummification. In this historical vignette, the authors examine paleoradiological and other evidence from ancient Egyptian skulls and mummies of all periods, from the Old Kingdom to Greco-Roman Egypt, to shed light on the development of transnasal surgery in this ancient civilization. The authors confirm earlier observations concerning the laterality of this technique, suggesting that ancient Egyptian excerebration techniques penetrated the skull base mostly on the left side. They also suggest that the original technique used to access the skull base in ancient Egypt was a transethmoidal one, which later evolved to follow a transsphenoidal route similar to the one used today to gain access to pituitary lesions.

    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.

    H5N1 highly pathogenic avian influenza virus (HPAIV) continues to cause mortality in poultry and threaten human health at a panzootic scale in Egypt since it was reported in 2006. While the early focus has been in Asia, recent evidence suggests that Egypt is an emerging epicenter for the disease. Despite control measures, epizootic transmission of the disease continues. Here, we investigate the persistence of HPAIV across wild passerine birds and domestic poultry between 2009 and 2012 and the potential risk for continuous viral transmission in Egypt. We use a new weighted cross J-function to investigate the degree and spatial temporal nature of the clustering between sightings of infected birds of different types, and the risk of infection associated with direct contact with infected birds. While we found no infection in wild birds, outbreaks occurred year round between 2009 and 2012, with a positive interaction between chickens and ducks. The disease was more present in the years 2010 and 2011 coinciding with the political unrest in the country. Egypt thus continues to experience endemic outbreaks of avian influenza HPAIV in poultry and an increased potential risk of infection to other species including humans. With the current trends, the elimination of the HPAIV infection is highly unlikely without a complete revamp of current policies. The application of spatial statistics techniques to these types of data may help us to understand the characteristics of the disease and may subsequently allow practitioners to explore possible preventive solutions.

    2013-11-01

    The paper presents an analysis of roadway factors and posted speed limits that affect the operating speed at multi-lane highways in Egypt. Field data on multi-lane highways in Egypt are used in this investigation. The analysis considers two categories of highways. The first consists of two desert roads (Cairo-Alexandria and Cairo-Ismailia desert roads) and the second consists of two agricultural roads (Cairo-Alexandria and Tanta-Damietta agricultural roads). The paper includes three separate relevant analyses. The first analysis uses the regression models to investigate the relationships between operating speed (V 85) as dependent variable, and roadway factors and posted speed as independent variables. The road factors are lane width, shoulder width, pavement width, median width, number of lanes in each direction, and existence of side access along each section. The second analysis uses the Artificial Neural Network (ANN) to explore the previous relationships while the third one examines the suitability of the posted speed limits on the roads under study. It is found that the ANN modeling gives the best model for predicting the operating speed and the most influential variables on V 85 are the pavement width, followed by the median width and the existence of side access along section. It is also found that the posted speed limit has a very small effect on the operating speed due to the bad behavior of drivers in Egypt. These results are so important for controlling V 85 on multi-lane rural highways in Egypt.

    Background Hepatocellular carcinoma (HCC) is a major health problem worldwide, including Egypt. In the recent past, HCC has become the second most prevalent cancer among men in Egypt. Since HCC has not been well studied in the rural population of Egypt, this case–control study was conducted to investigate the epidemiologic risk factors of HCC in the predominantly rural region of Gharbiah, Egypt. Methods A total of 150 cases and 150 controls matched to cases on age (±5 years) and sex were recruited from the Gharbiah Cancer Society and Tanta Cancer Center. Exposure data were collected by an interviewer-administered standardized questionnaire about epidemiologic, occupational, medical and family history of HCC. Conditional logistic regression was utilized to calculate unadjusted and adjusted odds ratios (ORs) and 95% confidence intervals (CI). The effect modification of HCC risk between viral infection and environmental risk factors was also assessed. Results Being an industrial worker was an independent risk for developing HCC (OR 3.54, 95% CI 1.18, 10.63) after adjusting for viral infection, schistosomiasis and tobacco smoking. High relative risk of HCC was observed among HCV-infected individuals who were farmers (OR 9.60, 95% CI 3.72, 24.76), industrial workers (OR 12.90, 95% CI 4.33, 38.43) or active smokers (OR 5.95, 95% CI 2.20, 16.08). Conclusion Occupational exposure may play an important role in the development of HCC. Farming, industrial exposures and cigarette smoking may increase the risk of HCC among HCV-seropositive individuals. Future research focusing on mechanisms of occupational exposures among HCV patients in this population is needed. PMID:21286338

    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.

    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.

  7. Female circumcision is curbed in Egypt.

    Wiens, J

    1996-08-01

    In the wake of the death of an 11-year-old girl the Egyptian government has banned any government-affiliated medical staff from performing female circumcision. Egyptian health policy has shifted from trying to control the practice by keeping it under government supervision towards condemnation. In October 1995 the health minister banned female circumcision from being carried out in state hospitals, a direct reversal of a 1994 decree that asked state hospitals to set aside one day a week for performing the procedure. The further restriction follows an incident in July 1996 when an 11-year-old girl bled to death in the rural area of Mansoora after being circumcised by a barber. Female genital mutilation in Egypt changed from an accepted custom to a political hot topic after the news network CNN in September 1994 featured the circumcision of a 9-year-old girl from Cairo. The footage embarrassed Egyptians and fueled an outcry by women's groups and nongovernmental organizations. Statistics compiled in 1994 by Egypt's former ministry of population estimated that between 70% and 90% of Egyptian women were circumcised. But a more recent survey puts the figure even higher, with 97% of women in both rural and urban areas having been circumcised. Circumcisions range from clitoridectomies to almost total removal of the outside genitalia. The practice seems to be rooted in both African tradition and Islamic beliefs, although many Islamic countries do not practice female circumcision. The main motivation seems to be in controlling women's sexual urges, and the belief that circumcision makes a woman more feminine. A university professor of gynecology teaches his medical students that circumcision is healthier for the woman. Most circumcisions in Egypt are performed by barbers or midwives, despite a sporadically enforced law forbidding the operation by anyone but a trained medical staff member. There is a high rate of complications, with some operations leading to infertility

    The diurnal temperature range (DTR) is an important climate-change variable. Seasonal and annual variability of DTR in Egypt was investigated based on a monthly dataset of 40 observatories distributing across the country. The trends were calculated using the Rho spearman rank test at the 95 % level of significance. The trends at the independent individual scale were compared with a regional series created for the whole country following the Thiessen polygon approach. A cross-tabulation analysis was performed between the trends of the DTR and the trends of maximum and minimum temperatures to account for directional causes of variability of the DTR at seasonal and annual scales. The physical processes controlling the DTR variability were also assessed in terms of large atmospheric circulations representing in the indices of the North Atlantic Oscillation (NAO), the East Atlantic (EA) pattern, El Niño Southern Oscillation (ENSO) index and the EAWR (East Atlantic/West Russia) Pattern. Also, the variability of the DTR was linked with anomaly of Sea Surface Temperature (SST). A cooling trend was observed in Egypt with strong behavior in winter and summer rather than fall and spring. The upwarding trend of the mean minimum temperature was mainly responsible for variability of the DTR rather than the mean maximum temperature. Also, the EA and the EAWR indices were the main indices accounted for most of variation in the DTR in Egypt, particularly in summer. Key words: trend analysis, temperature variability, Diurnal temperature range, atmospheric circulation, sea surface temperature, Egypt.

    The objectives in this statement are to characterize and explain the patterns of change in stratification and mobility in Egypt, over the last half century, by placing them within conceptual, explanatory, and historical contexts. First, literature relevant to the primary concepts of "class" and "status", is reviewed. Second, four institutions whose influence is fundamental in shaping these patterns are identified to form an explanatory context: family, polity, economy, and education. And third, an historical account is presented to demonstrate the interplay of these institutions and their consequences for stratification and mobility. For this, four periods are identified that are marked by change in the dominance of institutions and their corresponding influence on stratification and mobility. In addition to data available in relevant literature, this analysis utilizes primary data generated through a national probability household survey.

    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.

    Lauded alike by ancient civilizations and modern society, pharaonic Egyptian medicine remains an object of fascination today. This article discusses its surprisingly sophisticated understanding of a cardiovascular system. The term "cardiovascular system," however, carries assumptions and meanings to a modern audience, especially readers of this journal, which simply do not apply when considering ancient conceptions of the heart and vessels. For lack of better language, this article will use "cardiovascular" and similar terms while recognizing the anachronistic inaccuracy. After briefly summarizing ancient Egyptian medicine generally, it will review the anatomy, pathology, and treatment of the vasculature. The practice of mummification in ancient Egypt provides a unique opportunity for paleopathology, and the conclusion will explore evidence of arterial disease from a modern scientific perspective.

    Dwarfing the Nile, a river of dust flowed out of the deserts of northern Egypt on May 19, 2007. As the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Terra satellite passed overhead at 12:05 p.m. local time in Cairo, the sensor captured this image of the dust spreading northward over the Mediterranean Sea from the sandy deserts that span the country. At the margins of the plume, ribbons and ripples of dust are translucent, allowing a glimpse of the desert and water beneath, but in the center, the cloud is opaque, revealing nothing of the surface below. The part of north-central Egypt hidden by the dust plume is the Qattara Depression, the country's lowest point. Dipping down to 133 meters below sea level (436 feet), the depression is home to sandy deserts and dry lake beds that occasionally flood. The sand and fine, lake bed sediments are easily lofted into the air by strong winds that scour the area in late winter and early spring. In the eastern (right-hand) part of the image, the Nile River is lined by narrow ribbons of dull green vegetation. The fan-shaped delta is dotted with tan-colored spots, marking the location of cities and towns. The Nile Valley and Delta make up only a small fraction of the country's total land area, yet they support almost the entire population. The large image provided above has a spatial resolution (level of detail) of 250 meters per pixel. The MODIS Rapid Response Team provides this image in additional resolutions.

    The Sinai Peninsula is a triangular plateau lies in NE corner of Egypt, its head in the south at Ras Mohammed and its other sides between the Gulf of Aqaba and Gulf of Suez and the triangle base on the Mediterranean Sea. Sinai Peninsula is the most attractive region from the geological, geomorphological and environmental stand points of view because it displays a variety of simple and complex structural and landforms, (Abu Al-Izz,1971). In general, Sinai Peninsula reflects all geologic column of Egypt. Geomorphologically, Sinai Peninsula comprises many geomorphologic units such as mountains blocks, cliffs, isolated hills, wadies, hogbacks, questas, sand ridges, muddy and marshy lands, lakes and shorelines. This paper aims to define and measure geodiversity assessment index of the Sinai Peninsula as the quantitative variety of geological, topographical, geomorphological, hydrological and soil features. Some geodiversity indices maps for the above features produced for Sinai Peninsula were based on the methodology presented by (Pereira et al, 2012), it depends upon calculate of some geodiversity elements for overlay grid of the study area, which divided topographic, geological maps of the Sinai Peninsula with scale 1:500000 and satellite image (landsat 8, 27th October 2014, 12 bands, 30m). It divided into 743 squares (10x10 km), and some partial geodiversity indices such as geological, topographical, geomorphological, hydrological and soil indices were calculated by counting the number of each element inside each square, then the overall geodiversity index map produced by calculate the total number of all indices inside each square, the geodiversity index map were classified into some gradual categories by using isolines: very low, low, medium, high and very high.

  15. Environmental impact of pesticides in Egypt.

    PubMed

    Mansour, Sameeh A

    2008-01-01

    The first use of petroleum-derived pesticides in Egyptian agriculture was initiated in 1950. Early applications consisted of distributing insecticidal dusts containing DDT/BHC/S onto cotton fields. This practice was followed by use of toxaphene until 1961. Carbamates, organophosphates, and synthetic pyrethroids were subsequently used, mainly for applications to cotton. In addition to the use of about 1 million metric tons (t) of pesticides in the agricultural sector over a 50-yr period, specific health and environmental problems are documented in this review. Major problems represented and discussed in this review are human poisoning, incidental toxicity to farm animals, insect pest resistance, destruction of beneficial parasites and predators, contamination of food by pesticide residues, and pollution of environmental ecosystems. Several reports reveal that chlorinated hydrocarbon pesticide residues are still detectable in several environmental compartments; however, these residues are in decline. Since 1990, there is a growing movement toward reduced consumption of traditional pesticides and a tendency to expand use of biopesticides, including "Bt," and plant incorporated protectants (PIPs). On the other hand, DDT and lindane were used for indoor and hygienic purposes as early as 1952. Presently, indoor use of pesticides for pest control is widespread in Egypt. Accurate information concerning the types and amounts of Egyptian household pesticide use, or numbers of poisoning or contamination incidents, is unavailable. Generally, use of indoor pesticides is inadequately managed. The results of a survey of Egyptian farmers' attitudes toward pesticides and their behavior in using them garnered new insights as to how pesticides should be better controlled and regulated in Egypt.

    2008-02-28

    Road dust samples were collected during 2005 and polycyclic aromatic hydrocarbons (PAHs) were determined. Sites under investigation were selected to represent the different parts of Greater Cairo, Egypt. Estimation and spatial distribution pattern of PAHs in road dust were the main objectives of this study. The road dust samples were collected from 17 sites over greater Cairo. The concentration of PAHs was determined by using HPLC technique. Twelve common environmental PAHs were found to be distributed. The present data illustrated that the total average of PAHs over the investigated sites was ranged from 0.045 to 2.6 mg/kg. On individual scale, the highest concentrations were 1.031 and 1.028 mg/kg for pyrene and phenanthrene, meanwhile the lowest was benzo(a)pyrene with value 0.0001 mg/kg. The obtained results showed that the carcinogenic content of PAHs (naphthalene, benzo(a)anthracene, chrysene, benzo(b)fluoranthene, benzo(k)fluoranthene and benzo(a)pyrene) ranged from 0.8 to 46.6% of total PAHs. It has been concluded from the present work that PAHs concentrations are greater and closer to traffic routes and industrial activities.

    , obesity, high corn oil consumption, and the number of offspring contributed to the variability in occurrence of AFM1 in breast milk. Prevention and intervention approaches directed to risk factors of HCC can play a critical role in its prevention. In the case of HCV infection a prevention programme can be achieved by changing personal behaviors and/or cultural habits which are risk factors for HCV transmission, such as injection with contaminated syringes, blood transfusion, surgical operations, venous catheterization, use of common syringes, dental treatment and circumcision at home. Prevention of exposure to aflatoxins can be achieved either at community (via good agriculture practices) or individual levels (treatment or dietary interventions). In conclusion, due to the alarming increase in the incidence of HCC in Egypt, there is a need to further investigate the contribution of these emerging risk factors to the development of HCC in Egypt. This may enable us to determine the susceptibility to HCC among high-risk groups and to provide these individuals with effective measures for early prevention or intervention.

    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

    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.

    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.

    Egyptians are one of the first civilisations to practice the removal and examination of internal organs of humans. Their practices ranged from embalming to faith healing to surgery and autopsy. Modern radiological studies, together with various forensic techniques, allowed scientists unique glimpses of the state of health in Egypt 4000 years ago and discovered one of the earliest applications of autopsy, the main element of forensic medicine practice today. The Egyptian Forensic Medicine Authority handles a relatively large number of cases annually and depends on different assisting laboratories (forensic histopathology, microbiology, serology unit, DNA laboratory, forensic chemistry laboratory) as well as the Counterfeiting and Forgery unit. Crime scene investigations are performed mainly through the criminal laboratory related to the Ministry of Interior. Forensic Medicine is studied thoroughly in the faculty of medicine (undergraduates), as well as by forensic medical examiners at postgraduate level (diploma, master's and doctorate). This review recommends more scientific cooperation with universities in the field of forensic medicine and related sciences to solve various crimes with meticulous detail.

    An epizootic of Rift Valley fever (RVF) occurred in Egypt between April and August 1997. The signs among infected cattle and sheep were high fever, icterus, bloody diarrhoea and abortion. Aborted sheep foetuses and sera from the affected herds were collected in the Aswan and Assiut Provinces, Upper Egypt, for virological and serological examination. A cytopathic effect was detected in Vero cell cultures 48 h after inoculation with the foetal liver and spleen suspensions. The same suspensions caused paralysis and mortalities two to three days post intracerebral injection in mice. The isolated virus was identified using an agar gel precipitation test (AGPT) and a direct fluorescent antibody technique. Serological examination revealed that all tested sheep (57) and cattle (93) gave positive results to serological tests, using a complement fixation (CF), serum neutralisation (SN) and indirect immunofluorescence assay; while only 48 (84.2%) out of 57 sheep sera and 69 (74.2%) out of 93 cattle sera gave positive results using an AGPT. Titration of the serum samples indicated that SN is more sensitive than CF. Importation of infected ruminants, especially camels from the Sudan, is the principal source of infection. Aswan, the nearest Egyptian province to the Sudan, is the focus of RVF virus infection in Egypt. As a result of high insect populations, the epizootics of RVF have usually occurred during the summer in Egypt. Reoccurrence of epizootics from time to time indicates failure of the applied RVF vaccination programme in Egypt.

    Prospecting for iron ore occurrences was conducted by the Remote Sensing Center in Bahariya Oasis-El Faiyum area covering some 100,000 km squared in the Western Desert of Egypt. LANDSAT-1 satellite images were utilized as the main tool in the regional prospecting of the iron ores. The delineation of the geological units and geological structure through the interpretation of the images corroborated by field observations and structural analysis led to the discovery of new iron ore occurrences in the area of investigation.

    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.

    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).

    Alexandria port is the main Egyptian port at the Mediterranean Sea. It is connected to the Nile River through Nubaria canal, which is a main irrigation canal. The canal was designed to irrigate eight hundred thousand acres of agricultural lands, along its course which extends 100 km. The canal has three barrages and four locks to control the flow and allow light navigation by some small barges. Recently, it was decided to improve the locks located on the canal. More than 40 million US$ was invested in these projects. This decision was taken to allow larger barges and increase the transported capacity through the canal. On the other hand, navigation through canals and restricted shallow waterways is affected by several parameters related to both the channel and the vessel. Navigation lane width as well as vessel speed and maneuverability are affected by both the channel and vessel dimensions. Moreover, vessel dimensions and speed will affect the canal stability. In Egypt, there are no guide rules for navigation through narrow and shallow canals such Nubaria. This situation threatens the canal stability and safety of navigation through it. This paper discussed the characteristics of Nubaria canal and the guide rules for navigation in shallow restricted water ways. Dimensions limitation for barges navigating through Nubaria canal is presented. New safe operation rules for navigation in Nubaria canal are also presented. Moreover, the implication of navigation through locks on canal discharge is estimated. PMID:25685482

    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.

    We are developing the Atom Trap Trace Analysis (ATTA) method for the analysis of two long-lived rare krypton isotopes, ^81Kr (t_1/2=2.3 × 10^5 years, I.A. ˜ 10-13) and ^85Kr (t_1/2=10.8 years, I.A. ˜ 10-11). ^81Kr analyses can be used to determine the ages of old ice and groundwater in a range (5 × 10^4 - 2 × 10^6 years) beyond the reach of radio-carbon dating; Analyses of ^85Kr , a fission product of uranium and plutonium, can serve as a means to help verify compliance with the Nuclear Non-Proliferation Treaty. In ATTA, individual atoms of the desired isotope are selectively captured into a laser trap and detected by observing the fluorescence of trapped atoms. The first application of ATTA is dating the ancient groundwater of the Nubian Aquifer underneath the Western Desert of Egypt. This is one of the largest aquifers in the world. The residence time of its water are of great interest in fundamental geology as well as for utilitarian reasons. This work marks the beginning of a useful tool in Earth sciences. * This work is supported by the U.S. Department of Energy, Division of Nuclear Physics, under contract W-31-109-ENG-38.

  12. Global perspectives--the Middle East: Egypt.

    The Middle East region is characterised by the grouping of 20 countries with similar cultural traditions and religious concepts. The majority of the population of this region follows the religion of Islam, which considers all animals as important as humans, and others follow Christianity and Judaism. The majority of people dealing with animals have their own religious concepts, but most countries have no clear enforced official animal welfare regulations. Animal welfare activities in the Middle East region, as in Egypt for example, are carried out by various individuals, non-governmental organisations and the official Veterinary Services. The slaughter of animals for human consumption is in accordance with Islamic rites, which is the least painful method for the animals. Extensive production systems are the predominant systems in the region, and it is not common for animals in the region to suffer stress during production processes or slaughter. Although some success has been achieved in the area of animal welfare, as seen in improvements in health care, the development of modern abattoirs with proper facilities, and the establishment of policies for combating stray dogs, there are still major constraints to the implementation of effective animal welfare measures, including those for wildlife. These constraints include the lack of finances and the absence of effective legislative measures to prevent the trapping and/or hunting of wild animals for pleasure or illegal trade.

    Marine Constituent Dynamics in Coastal Egypt; Alexandria, Egypt, 20 November 2009; The Egyptian coastal area is a highly dynamic region in which materials (water, sediment, nutrients, and contaminants) are transported from various sources to the Mediterranean and Red seas. At a workshop in Egypt, U.S. and Egyptian scientists discussed these largely unquantified processes and how they interact to drive coastal ecology. A major goal of the workshop was to identify the most pressing research priorities for the region for both scientific and management purposes. The workshop concluded by recommending that international multidisciplinary efforts be undertaken to characterize water, nutrient, sediment, and contaminant delivery fluxes and mechanisms to coastal regions of the Nile Delta.

  14. Political challenges to biomedical universalism: kidney failure among Egypt's poor.

    PubMed

    2013-01-01

    Why do patients in need of kidney transplants in Egypt decline offers of kidney donation from their family members out of reluctance to cause them harm? Is it not universally the case that a living donor could live in complete health with a single remaining kidney? To address this conundrum, I discuss a case study from Egypt, in which patients reveal social, political, and environmental stresses on organ function that challenge the presumed universal efficacy and safety of kidney transplantation. I demonstrate that the biomedical position on the tolerable risks posed to the living donor is conditional and premised on particular social and historical contingencies that can be misaligned when applied in other contexts. Drawing on the work of Margaret Lock, I illustrate how analytical contributions of medical anthropologists can shed light on a political and public health impasse about how to legally regulate organ transplantation in Egypt.

    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

    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

    2013-09-01

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

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

    The shallow-water carbonates of the Middle Eocene in northern Egypt represent a Tethyan reef-rimmed carbonate platform with bedded inner-platform facies. Based on extensive micro- and biofacies documentation, five lithofacies associations were defined and their respective depositional environments were interpreted. Investigated sections were subdivided into three third-order sequences, named S1, S2 and S3. Sequence S1 is interpreted to correspond to the Lutetian, S2 corresponds to the Late Lutetian and Early Bartonian, and S3 represents the Late Bartonian. Each of the three sequences was further subdivided into fourth-order cycle sets and fifth-order cycles. The complete hierarchy of cycles can be correlated along 190 km across the study area, and highlighting a general "layer-cake" stratigraphic architecture. The documentation of the studied outcrops may contribute to the better regional understanding of the Middle Eocene formations in northern Egypt and to Tethyan pericratonic carbonate models in general.

    The northeast Nile Delta region exhibits a high incidence of early-onset pancreatic cancer. It is well documented that this region has one of the highest levels of pollution in Egypt. Epidemiologic studies have suggested that cadmium, a prevalent pollutant in the northeast Nile Delta region, plays a role in the development of pancreatic cancer. Objective: We aimed to assess serum cadmium levels as markers of exposure in pancreatic cancer patients and noncancer comparison subjects from the same region in Egypt. Design and Participants: We assessed serum cadmium levels of 31 newly diagnosed pancreatic cancer patients and 52 hospital comparison subjects from Mansoura, Egypt. Evaluation/Measurements: Serum cadmium levels were measured using a novel immunoassay procedure. Results: We found a significant difference between the mean serum cadmium levels in patients versus comparison subjects (mean ± SD, 11.1 ± 7.7 ng/mL vs. 7.1 ± 5.0 ng/mL, respectively; p = 0.012) but not in age, sex, residence, occupation, or smoking status. The odds ratio (OR) for pancreatic cancer risk was significant for serum cadmium level [OR = 1.12; 95% confidence interval (CI), 1.04–1.23; p = 0.0089] and farming (OR = 3.25; 95% CI, 1.03–11.64; p = 0.0475) but not for age, sex, residence, or smoking status. Conclusions: The results from this pilot study suggest that pancreatic cancer in the East Nile Delta region is significantly associated with high levels of serum cadmium and farming. Relevance to Clinical Practice/Public Health: Future studies should further investigate the etiologic relationship between cadmium exposure and pancreatic carcinogenesis in cadmium-exposed populations.

    There is substantial evidence that on average, urban children have better health outcomes than rural children. This paper investigates the underlying factors that account for the regional disparities in child malnutrition in three Arab countries, namely; Egypt, Jordan, and Yemen. We use data on a nationally representative sample from the most recent rounds of the Demographic and Health Survey. A Blinder-Oaxaca decomposition analysis is conducted to decompose the rural-urban differences in child nutrition outcomes into two components; one that is explained by regional differences in the level of the determinants (covariate effects), and another component that is explained by differences in the effect of the determinants on the child nutritional status (coefficient effects). Results show that the under-five stunting rates are 20 % in Egypt, 46.5 % in Yemen, and 7.7 % in Jordan. The rural- urban gap in child malnutrition was minor in the case of Egypt (2.3 %) and Jordan (1.5 %), while the regional gap was significant in the case of Yemen (17.7 %). Results of the Blinder-Oaxaca decomposition show that the covariate effect is dominant in the case of Yemen while the coefficients effect dominates in the case of Jordan. Income inequality between urban and rural households explains most of the malnutrition gap. Results were robust to the different decomposition weighting schemes. By identifying the underlying factors behind the rural- urban health disparities, the findings of this paper help in designing effective intervention measures aimed at reducing regional inequalities and improving population health outcomes.

    Background: Manilkara zapota (L.) Van Royen is an evergreen tree, native to the tropical Americas and introduced to Egypt as a fruiting tree in 2002. No previous study was reported on the plant cultivated in Egypt. Materials and Methods: In this study, the leaves of the plant cultivated in Egypt were subjected to phytochemical and biological investigations. The lipoidal matter was analyzed by GLC. Five compounds were isolated from the petroleum ether and ethyl acetate fractions of the alcoholic extract of the leaves by chromatographic fractionation on silica gel and sephadex, the structures of these compounds were identified using IR, UV, MS, 1H-NMR and 13C-NMR. The LD50 of the alcoholic and aqueous extracts of the leaves was determined and their antihyperglycemic, hypocholesterolemic and antioxidant activities were tested by enzymatic colorimetric methods using specific kits. Results: Unsaturated fatty acids represent 32.32 % of the total fatty acids, oleic acid (13.95%), linoleidic acid (10.18 %) and linoleic acid (5.96 %) were the major ones. The isolated compounds were identified as lupeol acetate, oleanolic acid, apigenin-7-O-α-L-rhamnoside, myricetin-3-O-α-L-rhamnoside and caffeic acid. This is the first report about isolation of these compounds from Manilkara zapota except myricetin-3-O-α-L-rhamnoside, which was previously isolated from the plant growing abroad. The LD50 recorded 80 g/Kg b. wt. for both the tested extracts, so they could be considered to be safe. They exhibited antihyperglycemic, hypocholesterolemic and antioxidant activities. Conclusion: The observed biological activities were attributed to the different chemical constituents present in the plant mainly its phenolic constituents. PMID:22518080

    There is substantial evidence that on average, urban children have better health outcomes than rural children. This paper investigates the underlying factors that account for the regional disparities in child malnutrition in three Arab countries, namely; Egypt, Jordan, and Yemen. We use data on a nationally representative sample from the most recent rounds of the Demographic and Health Survey. A Blinder-Oaxaca decomposition analysis is conducted to decompose the rural-urban differences in child nutrition outcomes into two components; one that is explained by regional differences in the level of the determinants (covariate effects), and another component that is explained by differences in the effect of the determinants on the child nutritional status (coefficient effects). Results show that the under-five stunting rates are 20 % in Egypt, 46.5 % in Yemen, and 7.7 % in Jordan. The rural- urban gap in child malnutrition was minor in the case of Egypt (2.3 %) and Jordan (1.5 %), while the regional gap was significant in the case of Yemen (17.7 %). Results of the Blinder-Oaxaca decomposition show that the covariate effect is dominant in the case of Yemen while the coefficients effect dominates in the case of Jordan. Income inequality between urban and rural households explains most of the malnutrition gap. Results were robust to the different decomposition weighting schemes. By identifying the underlying factors behind the rural- urban health disparities, the findings of this paper help in designing effective intervention measures aimed at reducing regional inequalities and improving population health outcomes.

    Although avian metapneumovirus (aMPV) infection has been reported in most regions of the world, to date, only subtype B has been detected in Egypt. At the end of November 2013, dry oropharyngeal swabs were collected during an outbreak of respiratory diseases in a free-range, multi-age turkey dealer farm in Northern Upper Egypt. The clinical signs that appeared when turkeys were 3 weeks-old were characterized by ocular and nasal discharge and swelling of sinuses. aMPV of subtype A was detected by real-time reverse transcription-polymerase chain reaction. In order to confirm the results and obtain more information on the molecular characteristics of the virus, F and G protein genes were partially sequenced and compared with previously published sequences deposited in GenBank by using BLAST. Subtype of the strain was confirmed by sequencing of partial F and G protein genes. The highest percentages of identity were observed when G sequence of the Egyptian strain was compared with the sequence of an aMPV-A isolated in Nigeria (96.4 %) and when the F sequence was compared with strains isolated respectively in Italy and in UK (97.1 %). Moreover, the alignment of the sequences with commercial subtype A vaccine or vaccine-derived strains showed differences in the Egyptian strain that indicate its probable field origin. The detection of aMPV in the investigated turkey flock highlights some relevant epidemiological issues regarding the role that multi-age farms and dealers may play in perpetuating aMPV infection within and among farms. To our knowledge, this is the first report of aMPV subtype A in Egypt.

    The Red Sea golf resort in Sharm El Sheik, Egypt, where President Clinton met with Israeli Prime Minister Ehud Barak and Palestinian Authority President Yasser Arafat, stands out against the desert landscape in this image acquired on August 25, 2000.

    This image of the southern tip of the Sinai Peninsula shows an area about 30 by 40 kilometers (19 by 25 miles) in the visible and near infrared wavelength region. Vegetation appears in red. The blue areas in the water at the top and bottom of the image are coral reefs. The airport is visible just to the north of the golf resort.

    Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) is one of five Earth-observing instruments launched December 18, 1999, on NASA's Terra satellite. The instrument was built by Japan's Ministry of International Trade and Industry. A joint U.S./Japan science team is responsible for validation and calibration of the instrument and the data products. Dr. Anne Kahle at NASA's Jet Propulsion Laboratory, Pasadena, Calif., is the U.S. Science team leader; Moshe Pniel of JPL is the project manager. ASTER is the only high resolution imaging sensor on Terra. The primary goal of the ASTER mission is to obtain high-resolution image data in 14 channels over the entire land surface, as well as black and white stereo images. With revisit time of between 4 and 16 days, ASTER will provide the capability for repeat coverage of changing areas on Earth's surface.

    The broad spectral coverage and high spectral resolution of ASTER will provide scientists in numerous disciplines with critical information for surface mapping, and monitoring dynamic conditions and temporal change. Example applications are: monitoring glacial advances and retreats, monitoring potentially active volcanoes, identifying crop stress, determining cloud morphology and physical properties, wetlands Evaluation, thermal pollution monitoring, coral reef degradation, surface temperature mapping of soils and geology

    Depressions of the Western Desert of Egypt (specifically, Kharga, Farafra, and Kurkur regions) are mainly occupied by shales that are impermeable, but easily erodible by rainfall and runoff, whereas the surrounding plateaus are composed of limestones that are permeable and more resistant to fluvial erosion under semiarid to arid conditions. Scallop-shaped escarpment edges and stubby-looking channels that cut into the plateau units are suggestive of slumping of limestones by ground-water sapping at the limestone-shale interfaces, removal of slump blocks by weathering and fluvial erosion, and consequent scarp retreat. Spring-derived tufa deposits found near the limestone escarpments provide additional evidence for possible ground-water sapping during previous wet periods. A computer simulation model was developed to quantify the ground-water sapping processes, using a cellular automata algorithm with coupled surface runoff and ground-water flow for a permeable, resistant layer over an impermeable, friable unit. Erosion, deposition, slumping, and generation of spring-derived tufas were parametrically modeled. Simulations using geologically reasonable parameters demonstrate that relatively rapid erosion of the shales by surface runoff, ground-water sapping, and slumping of the limestones, and detailed control by hydraulic conductivity inhomogeneities associated with structures explain the depressions, escarpments, and associated landforms and deposits. Using episodic wet pulses, keyed by {delta}{sup 18}O deep-sea core record, the model produced tufa ages that are statistically consistent with the observed U/Th tufa ages. This result supports the hypothesis that northeastern African wet periods occurred during interglacial maxima. The {delta}{sup 18}O-forced model also replicates the decrease in fluvial and sapping activity over the past million years, as northeastern Africa became hyperarid. The model thus provides a promising predictive tool for studying long

    In this study an outbreak with Sheeppox virus (SPPV) and Orf virus (ORFV) in one sheep herd in the Qalubia province, Egypt, was investigated. Both, SPPV and ORFV caused clinically manifest infections among sheep. The affected sheep showed skin lesions around the mouth or all over the body. Therefore, reliable diagnosis should confirm the aetiology of the infection and then reduce spread of the diseases in the affected areas. Clinical samples were investigated by virus isolation, PCR and real-time PCR assays. Furthermore, PCR-products of SPPV and ORFV isolates were sequenced and alignment to reference isolates was performed for phylogenetic analyses. The laboratory diagnosis showed that real-time PCR assay was more accurate and sensitive than conventional PCR and virus isolation. In phylogenetic analysis of the A29L gene genetic differences between SPPV field strains were not observed and the strains showed 100% homology with two SPPV isolates from Kazakhstan and one isolate from Turkey. The ORFV field strains are in the P55 gene genetically distinct from another and from other published isolates from Egypt 2006 and 2009. PMID:27529993

    Peste des petits ruminants (PPR) is an acute, highly contagious fatal disease of small ruminants characterized by high fever, ocular and nasal discharge, pneumonia, erosive stomatitis and severe enteritis that ultimately results in high mortalities. Peste des petits ruminants virus (PPRV) is widely distributed and endemic in several African, middle eastern and south Asian countries and it poses a threat to European countries. Egyptian veterinary medical authorities stated that Egypt is free from PPRV and the only measures for disease control are test and slaughter of infected population to maintain the free status. The aim of our investigation was to detect PPRV in Ismailia province as an indicator of the infection status in Egypt and perform molecular characterization of the emerging virus to gain insight into the origin of circulating virus. A total of 40 representative clinical samples, from a single goat case and goat flock in 2010 and sheep flock in 2012, were tested for PPRV by RT-PCR. About 21 (52.5%) samples were positive. The phylogenetic analysis of the detected viruses revealed circulation of PPRV lineage IV. The circulating viruses are closely related to Sudanese and Saudia Arabian strains with nucleotide identity ranged from 99.2% to 99.6%, respectively. Also, it is closely related to Moroccan 2008 viruses with identities ranged from 97.6% to 98%. Epidemiological investigation at the national level is recommended for monitoring PPRV spread and implementing an appropriate control program.

    Medemia argun is a mysterious and little known monotypic fan palm from the Nubian Desert Oases of southern Egypt and northern Sudan. Its fruits have been found in the tombs from the 5th Dynasty (ca. 2500 BC) to Roman times (6-7th century AD), including the celebrated tomb of Tutankhamun. In ancient Egypt, the fruits of this palm were widely distributed and were highly valued, as confirmed by their frequent occurrence in offerings in the tombs. In order to elucidate the chemical composition of the phenolic fraction, phytochemical investigation of the BuOH extract of fruits was carried out to afford eight compounds (1-8), among which was the new 2,4-dihydroxy-6-methylacetophenone 2-0-β-D-glucopyranoside (1). With the aim to investigate if the high shelf life of M argun fruits could be related to the occurrence of antioxidant principles that were able to prevent oxidative reactions, the evaluation was carried out of the in vitro antioxidant activity by Trolox equivalent antioxidant capacity (TEAC) assay of the extract and isolated compounds.

    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

    Background Hepatocellular carcinoma (HCC) is a common cancer worldwide as well as in Egypt with hepatitis C and B, alcohol and aflatoxins being the commonest risk factors. Aim The objective of this study was to assess the prognostic factors affecting overall survival (OS) of untreated HCC in Egypt. Methods This retrospective study was conducted at Tanta Cancer Center, Egypt where 288 HCC cases who received no specific therapy and were followed-up until death were identified. The impact of possible prognostic factors on OS was assessed using the log-rank test (univariate analyses) and Cox regression method (multivariate analysis). Results The median OS of untreated HCC was 2.3 months (95% confidence interval: 1.9–2.6). The 1, 3, 6, 12, 24 months OS rates were 84%, 42%, 21%, 9%, and 3%, respectively. All cases had died by 46 months. Male sex, advanced Child-Pugh class, the clinical presentation of ascites, cough, fatigue, and the presence of metastases were associated with poor survival (P<0.05 for all). In multivariate analysis; cough, presence of ascites, and Child-Pugh class were independent predictors of poor survival. Conclusion OS in untreated HCC in Egypt is very short. Many factors interact to produce this dismal survival. PMID:27508189

    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.

    Developing countries, including Egypt and North African countries, need to improve their quality of research by enhancing international cooperation and exchanges of scientific information, as well as competing for obtaining international funds to support research activities. Research must comply with laws and other requirements for research that involves human subjects. The purpose of this article is to overview the status of health research ethics in Egypt and North African countries, with reference to other Middle Eastern countries. The EU and North African Migrants: Health and Health Systems project (EUNAM) has supported the revision of the status of health research ethics in Egypt and North African countries, by holding meetings and discussions to collect information about research ethics committees in Egypt, and revising the structure and guidelines of the committees, as well as reviewing the literature concerning ethics activities in the concerned countries. This overview has revealed that noticeable efforts have been made to regulate research ethics in certain countries in the Middle East. This can be seen in the new regulations, which contain the majority of protections mentioned in the international guidelines related to research ethics. For most of the internationally registered research ethics committees in North African countries, the composition and functionality reflect the international guidelines. There is growing awareness of research ethics in these countries, which extends to teaching efforts to undergraduate and postgraduate medical students.

    2014-12-01

    Middle East and North Africa (MENA) countries have a diversity of populations with similar life style, dietary habits, and vascular risk factors that may influence stroke risk, prevalence, types, and disease burden. Egypt is the most populated nation in the Middle East with an estimated 85.5 million people. In Egypt, according to recent estimates, the overall prevalence rate of stroke is high with a crude prevalence rate of 963/100,000 inhabitants. In spite of disease burden, yet there is a huge evidence practice gap. The recommended treatments for ischemic stroke that are guideline include systematic supportive care in a stroke unit or stroke center is still deficient. In addition, the frequency of thrombolysis in Egypt is very low for many reasons; the major one is that the health insurance system is not covering thrombolysis therapy in nonprivate sectors so patients must cover the costs using their own personal savings; otherwise, they will not receive treatment. Another important factor is the pronounced delay in prehospital and in hospital management of acute stroke. Improvement of stroke care in Egypt should be achieved through multi and interdisciplinary approach including public awareness, physicians' education, and synergistic approach to stroke care with Emergency Medical System.

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

    PubMed

    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.

    The relationship between history of schistosomiasis and bladder cancer risk was investigated using data from a case-control study conducted between January 1994 and July 1996 in Alexandria, Egypt. Cases were 190 subjects with incident, histologically confirmed invasive cancer of the bladder, and controls were 187 subjects admitted to hospital for acute, non-neoplastic, non-urinary tract conditions. Eighty-six cases (45%) vs 69 controls (37%) reported a history of urinary schistosomiasis. The corresponding multivariate odds ratio (OR) of bladder cancer -- after allowance for age, sex, education, smoking, other urinary infections and high-risk occupations -- was 1.72 (95% confidence interval (CI) 1.0-2.9). The ORs were 0.22 (95% CI 0.1-0.4) for intestinal schistosomiasis and 0.32 (95% CI 0.1-1.9) for schistosomiasis of other types. The OR for urinary schistosomiasis was higher in subjects who were younger at first diagnosis (OR of 3.3 for <15 years) and in those with a long time since first diagnosis (OR of 3.0 for > or = 35 years). The ORs were 15.8 for male ever-smokers with a history of urinary schistosomiasis, compared with never-smokers without such a history, and 3.2 for men ever-infected with urinary Schistosoma haematobium and ever-employed in high-risk occupations, compared with those never-infected and with no high-risk occupational history. This study confirms that clinical history of urinary schistosomiasis is significantly, but modestly, associated with increased bladder cancer risk, explaining some 16% of bladder cancer cases in this Egyptian population.

    Abstract The aim of this study was to assess childhood lead exposure in a representative sample of Cairo, and to investigate the possible risk factors and sources of exposure. 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

  15. Space Radar Image of Safsaf Oasis, Egypt

    NASA Technical Reports Server (NTRS)

    1994-01-01

    This three-frequency space radar image of south-central Egypt demonstrates the unique capability of imaging radar to penetrate thin sand cover in arid regions to reveal hidden details below the surface. Nearly all of the structures seen in this image are invisible to the naked eye and to conventional optical satellite sensors. Features appear in various colors because the three separate radar wavelengths are able to penetrate the sand to different depths. Areas that appear red or orange are places that can be seen only by the longest wavelength, L-band, and they are the deepest of the buried structures. Field studies in this area indicate L-band can penetrate as much as 2 meters (6.5 feet) of very dry sand to image buried rock structures. Ancient drainage channels at the bottom of the image are filled with sand more than 2 meters (6.5 feet) thick and therefore appear dark because the radar waves cannot penetrate them. The fractured orange areas at the top of the image and the blue circular structures in the center of the image are granitic areas that may contain mineral ore deposits. Scientists are using the penetrating capabilities of radar imaging in desert areas in studies of structural geology, mineral exploration, ancient climates, water resources and archaeology. This image is 51.9 kilometers by 30.2 kilometers (32.2 miles by 18.7 miles) and is centered at 22.7 degrees north latitude, 29.3degrees east longitude. North is toward the upper right. The colors are assigned to different radar frequencies and polarizations as follows: red is L-band, horizontally transmitted and received; green is C-band, horizontally transmitted and received; and blue is X-band, vertically transmitted and received. The image was acquired by the Spaceborne Imaging Radar-C/X-band Synthetic Aperture Radar (SIR-C/X-SAR) on April 16, 1994, on board the space shuttle Endeavour. SIR-C/X-SAR, a joint mission of the German, Italian and United States space agencies, is part of NASA's Mission

    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.

    This study was performed for the purpose of investigating the prevalence and the species composition of Sarcocystis spp. in buffaloes in Assiut province, Egypt. Macroscopically we reported the infection of buffaloes with Sarcocystis fusiformis, while microscopically three Sarcocystis species (Sarcocystis cruzi, Sarcocystis levinei and Sarcocystis hominis) cysts were recognized, and were differentiated by their morphological features using both histopathological sections and electron microscope scanning. Regarding the prevalence of Sarcocystis species among buffaloes in Assiut province, we reported that, using gross examination of 90 buffaloes' esophagus, only 23 samples out of 90 (25.5 %) were found to be infected; on the other hand, by using microscopical examination, the prevalence was 27.7 % (25 samples out of 90 samples were found to be infected). Using ELISA, 85 samples out of 90 (94.4 %) were found positive, an overall prevalence of 94.4 %. In this work we concluded that customary meat inspection methods in abattoirs in Egypt are insufficient for detecting Sarcocystis infection. Due to the presence of hidden or microscopic cysts, we strongly recommend the use of combined microscopical examination and ELISA for Sarcocystis diagnosis, to avoid human infection of such zoonotic parasite and to control the consequent disease. In addition, this study introduced the first report of S. cruzi in buffaloes in Egypt, and proved the hypothesis that S. cruzi is able to use animals such as water buffalo as intermediate hosts.

    Deviation from the normative sex-pattern of infant deaths is so large in Egypt that nearly 1/3 of female deaths can be attributed to a sex-specific cause: lesser care of the female child. This article reports on child neglect which may account for the relatively lower survival rate of the female infant, despite its biological advantage over the male. This knowledge is seen as vital in planning interventions. The investigation answers 3 questions relating to the sex-specific factors of death among female infants: do girls display a poorer level of nutrition compared to boys? Is there evidence to show that sickness episodes of female infants are treated more carelessly than those of male infants? Are there reasons to believe that girls are more exposed to life-threatening psychological factors than are boys? A group of 598 families in low-income districts of Cairo was randomly chosen to receive regular monthly visits by a team of trained field invstigators over a 1-year period. The sample is thought to represent life in urban quarters of Egypt, described as pervasively rural in orientations despite urban occupations and living conditions. The study finds no significant sex difference in nutritional status until the 6th month of life. Around this period, 2/5 of the female group but 1/4 of the male show signs of malnutrition as measured by weight. The difference continues to increase and is very statistically significant by the end of the year. Nutritional status of female infants tended to decline with an addition of daughters in the family. Also, at birth orders 2 ot 5 and in large families of 4-5 children, the relative nutritional disadvantage of the female infant is statistically significant. Moreover, a very distinct sex-difference in dietary patterns is observed as no boy was deprived of supplementary feeding during the 2nd 1/2 of the year but only 1/15 girls received food other than breast milk during this period.

    Pseudococcidae (mealybugs) is a large taxonomic group, including a number of agronomic pests. Taxonomic identification of mealybug species is a recurrent problem and represents a major barrier to the establishment of adequate pest management strategies. We combined molecular analysis of three DNA markers (28S-D2, cytochrome oxidase I and internal transcribed spacer 2) with morphological examination, for the identification of 176 specimens collected from 40 mealybug populations infesting various crops and ornamental plants in Egypt and France. This combination of DNA and morphological analyses led to the identification of 17 species: seven in Egypt (Planococcus citri (Risso), Planococcus ficus (Signoret), Maconellicoccus hirsutus (Green), Ferrisia virgata (Cockerell), Phenacoccus solenopsis Tinsley, Phenacoccus parvus Morrison and Saccharicoccus sacchari (Cockerell)) and 11 in France (Planococcus citri, Pseudococcus viburni Signoret, Pseudococcus longispinus (Targioni-Tozzetti), Pseudococcus comstocki (Kuwana), Rhizoecus amorphophalli Betrem, Trionymus bambusae (Green), Balanococcus diminutus (Leonardi), Phenacoccus madeirensis Green, Planococcus vovae (Nasonov), Dysmicoccus brevipes (Cockerell) and Phenacoccus aceris Signoret), Pl. citri being found in both countries. We also found genetic variation between populations considered to belong to the same species, justifying further investigation of the possible occurrence of complexes of cryptic taxa.

    Canine rabies virus variant has been eliminated in the United States and multiple other countries. Globally, however, dogs remain the principal source for human rabies infections. The World Health Organization recommends that when dogs cross international borders, national importing authorities should require an international veterinary certificate attesting that the animal did not show signs of rabies at the time of shipment, was permanently identified, vaccinated, or revaccinated, and had been subjected to a serologic test for rabies before shipment. On June 8, 2015, an adult female dog that had recently been picked up from the streets of Cairo, Egypt, and shipped by a U.S. animal rescue organization to the United States was confirmed to have rabies by the Virginia Department of General Services Division of Consolidated Laboratory Services (DCLS). This dog was part of a large shipment of dogs and cats from Egypt that rescue organizations had distributed to multiple states for adoption. During the investigation, public health officials learned that the rabies vaccination certificate used for entry of the rabid dog into the United States had intentionally been falsified to avoid exclusion of the dog from entry under CDC's current dog importation regulations. This report underscores the ongoing risk posed by U.S. importation of domestic animals that have not been adequately vaccinated against rabies.

    Household-level fertility research was examined with the broader contexts of the demographic transition and public policy. The Easterlin-Crimmins (1982, 1985) model was the framework chosen for the examination. It was modified and applied to a sample of rural Egyptian households. An interesting dimension of the Easterlin-Crimmins framework is the presence of a phase of development where fertility is constrained by supplying factors -- a phenomenon most likely to occur in rural settings in the 3rd world. Thus the data set from rural Egypt offers a good opportunity to explore this aspect of their model. The framework also is useful for delineating the relative importance of behavioral versus family planning factors in explaining changes in the fertility of a population. On average, estimated Cn (surviving natural fertility) approximately equaled Cd (desired surviving family size) for the noncontracepting subpopulation of rural Egypt. These families had little or no motivation for contraception and remain in the premodernization Phase I, i.e., the desired number of surviving children exceeds the number of surviving children under a natural fertility regime. In contrast, the noncontracepting subset of families drawn from both the rural and urban areas of Sri Lanka and Colombia, already had embarked on Phase II, i.e., the supply constraint is released, but contraception is too costly. By applying child survivorship rates (s) to actual fertility for the contracepting subsets of women, on average, actual surviving fertility exceeded Cd by 1.0 children in rural Egypt, 2.0 in Sri Lanka, and 2.9 in Colombia. All 3 of these populations are in Phase III, i.e., contraception becomes increasingly pervasive as the gap between Cn and Cd widens and contraceptive costs decline. The methodology offers promise for identifying the separate influences of family planning and socioeconomic change. The results provided insights into the basic determinants underlying the demographic

    Because of a growing cultural and religious sensitivity and controversy over reproductive health issues, particularly abortion, this area remains relatively unexplored in Egypt. This study was conducted using a participatory approach to determine the morbidity and determinants of abortion in rural Upper Egypt. In all, 1025 women from six villages in Upper Egypt were included in the study. Information regarding the incidence of abortion, patterns of health care utilization and risk factors was obtained using a structured interview format. The local dialect was used in formulating questions and they were revised and amended by a panel of local leaders, interviewers and representatives of the study population. Interviewers were local educated (secondary or university level) female volunteers. Information about exposure to 17 risk factors was also collected and statistical analysis was done by estimating the odds ratio and applying a test of statistical significance. Then, a multivariate logistic regression model was applied to control for possible interactions and confounding effects. The results were that 40.6% (n=416) had aborted at least once; of them 24.6% (n=252) had aborted more than once and were designated as recurrent aborters. The lifetime prevalence of recurrent abortion was estimated to be 25% and nearly 21% of pregnancies were aborted. The incidence of abortion was estimated to be 265 per 1000 live birth. Only 21.9% (n=91) of women received medical care for the last abortion. The vast majority of women (92%, n=299) who did not seek medical help received help from traditional and domestic sources. These sources are midwife (59.9%, n=179), relative or neighbour (29.8%, n=89), and traditional practitioner (10.4%, n=31). The multivariate analysis revealed that the incidence of abortion is significantly associated with gravidity, consanguinity, and mother occupation, while recurrent abortion is associated with gravidity, consanguinity and woman's age at

    As part of the implementation of a bar-code-based system to track radioactive sealed sources (RSS) in Egypt, the Regulatory Authority Information System Personal Digital Assistant (RAIS PDA) Application was developed to extend the functionality of the International Atomic Energy Agency's (IAEA's) RAIS database by allowing users to download RSS data from the database to a portable PDA equipped with a bar-code scanner. [1, 4] The system allows users in the field to verify radioactive sealed source data, gather radioactive sealed source audit information, and upload that data to the RAIS database. This paper describes the development of the RAIS PDA Application, its features, and how it will be implemented in Egypt. (authors)

    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.

    Comparisons of satellite images of the Nile Delta, acquired in 1972, 1984 and 1990, indicate that urban growth is endangering Egypt's agricultural productivity. Urban areas occupied a minimum of 3.6%, 4.7% and 5.7% of the Delta in 1972, 1984 and 1990, respectively, an increase of 58% in 18 years. Approximately half of this increase occurred between 1984 and 1990. If this trend continues, Egypt could lose 12% of its total agricultural area to urbanization by 2010. Despite the fact that growth is pronounced around the cities, it is the growth around the thousands of small villages that poses the largest threat to the agricultural productivity of the Nile Delta. The cumulative growth rate for the cities and large villages between 1972 and 1990 is 37%, and that for the small villages is 77% for the same time period.

    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

    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.

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

    Continuous circulation of influenza A(H5N1) virus among poultry in Egypt has created an epicenter in which the viruses evolve into newer subclades and continue to cause disease in humans. To detect influenza viruses in Egypt, since 2009 we have actively surveyed various regions and poultry production sectors. From August 2010 through January 2013, >11,000 swab samples were collected; 10% were positive by matrix gene reverse transcription PCR. During this period, subtype H9N2 viruses emerged, cocirculated with subtype H5N1 viruses, and frequently co-infected the same avian host. Genetic and antigenic analyses of viruses revealed that influenza A(H5N1) clade 2.2.1 viruses are dominant and that all subtype H9N2 viruses are G1-like. Cocirculation of different subtypes poses concern for potential reassortment. Avian influenza continues to threaten public and animal health in Egypt, and continuous surveillance for avian influenza virus is needed.

  18. Lower Eocene carbonate facies of Egypt: paleogeographic and tectonic implications

    SciTech Connect

    Garrison, R.E.

    1983-03-01

    The northern Arabo-Nubian craton witnessed a major Late Cretaceous-early Tertiary marine transgression that culminated in the deposition of widespread shelf-sea carbonates during Early Eocene (Ypresian) time. Outer shelf facies characterize exposures in central Egypt (Assiut, Luxor, Kharga), and are composed primarily of rhythmically interbedded chalk and micritic limestone with minor intercalated marine hardgrounds. To the south (Kurkur-Dungul), these fine-grained lithologies give way to inner shelf foraminiferal wackestones and grainstones, typical Tethyan Nummulitic facies. Missing in southern Egypt is the restricted dolomitic evaporitic facies predicted by the Irwin model and observed in the lower Eocene of the Sirte basin to the west and the Arabian Platform to the east. Comparing the areal distribution of these lower Eocene carbonates to coeval facies developed across the remained of northern Africa and Arabia reveals the presence of a broad marine embayment which extended through central and eastern Egypt into northern Sudan during Ypresian time. The widespread subsidence that resulted in the development of this features may have been an effect of regional crustal attenuation preceding the rifting of the Red Sea. Concomitant with this regional subsidence were localized uplift and extensional block faulting in the vicinity of the incipient Red Sea rift (the Safaga-Quseir coastal plain). Here, lower Eocene carbonate facies are indicative of shallow water platforms developed on horst blocks, and deeper water, turbidite-fed basins in intervening grabens.

    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

    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.

    The site of investigation, 15th May city, is a new suburb of Helwan, at about 35 km south of Cairo, Egypt. The work is aimed to investigate the rock mass stability at 'Quarter 27' in 15th May City. A controlled source electromagnetic (CSEM) approach developed earlier by IGF UB RAS (Geophysical Federal Institute, Ural Branch of Russian Academy of Science) is applied to image the ranked deformation levels in the massive structure. The wide profile system of observation has been used to monitor the three components of the alternating magnetic field along predefined measuring lines in the study area. Four cycles of observation have been carried out in 2008, 2010, 2011, and 2012. The acquired data sets have been subjected to analytical processing procedure to estimate the changes in the geotechnical parameters during the time of these four cycles of observation. The analytical treatments provided good information about the structure of the rock massive and its rank of degradation, the lateral distribution of the geotechnical heterogeneity, and finally a conclusive outcome about foundation stability. We conclude that the general dynamic state close to the destruction level within the investigation area is getting worse over the time; this is reflected in the crack's densities and positions, also on the changes in the lateral distribution of geoelectric heterogeneity as an indicator of the saturation of the surface rock in the study area with water [1]. 1.

    One of the possible ways of overcoming the deficit of animal protein in human nutrition is that of increasing the livestock and increasing the performance of the animals. Egypt wants to follow this way, especially utilizing the possibilities offered by the newly reclaimed land. For this purpose efficient herds must be developed in the newly reclaimed areas in large-scale production units and under optimum farming conditions. This includes above all a continuous supply of feedstuff by means of intensive field forage cultivation. Starting in August 1973, the test station for agricultural machinery of the GDR VVB Land-und Nahrungsgütertechnik at El Ghasair has investigated the problems connected with a continuous daily supply of fresh feed-stuff to large livestock (cattle) and with preservation methods suited to this aim. First results are reported of applying an advanced technology - and partly GDR farm machinery - in cultivating and harvesting green fodder and hay, using Alexandrian clover and lucern.

    2011-01-01

    This article investigates change and continuity in anxieties about shopping during the first half of the twentieth century in Egypt to argue that department stores and their salesclerks became critical sites for enacting and challenging new notions of sexuality and citizenship. Retail innovations, such as commission pay, display, free entry, and large commercial staffs, became understood as sexual and moral problems because department stores blurred the boundaries between classes and were public spaces where unrelated men and women could mix. These concerns about sexuality in the 1920s were recycled and amplified in the late 1940s and early 1950s when salesclerks again came under scrutiny during debates over citizenship and ethnicity. I argue that the particular way this latter debate was barnacled by the concerns of the 1920s helped to delineate the broader society's reaction to the challenges of defining Egyptian nationality.

    The present study focused on the identification of emotions in cross-cultural conditions on different continents and among subjects with divergent language backgrounds. The aim was to investigate whether the perception of the basic emotions from nonsense vocal samples was universal, dependent on voice quality, musicality, and/or gender. Listening tests for 350 participants were conducted on location in a variety of cultures: China, Egypt, Estonia, Finland, Russia, Sweden, and the USA. The results suggested that the voice quality parameters played a role in the identification of emotions without the linguistic content. Cultural background may affect the interpretation of the emotions more than the presumed universality. Musical interest tended to facilitate emotion identification. No gender differences were found.

    We investigate the relationship between reproduction and functional health in later life among women and men in the resource-poor and gender-stratified setting of Ismailia governorate, Egypt. Analyses of survey data collected in 2003 show a statistically significant positive association between parity and difficulty with activities of daily living (ADLs), controlling for demographic and socio-economic factors and other co-morbid conditions. We also find that the number of daughters (but not sons) is associated with worse physical functioning, and this association is more pronounced for older fathers than for older mothers. Our results indicate that both biological and social pathways link fertility and later-life health in this context, and that prescribed familial roles may underlie the differential impact of sons and daughters on the health of mothers and fathers in later life.

    Hand hygiene of health-care staff is one of the most important interventions in reducing transmission of nosocomial infections. This qualitative study aimed to understand the behavioural determinants of hand hygiene in order to develop sustainable interventions to promote hand hygiene in hospitals. Fourteen focus group discussions were conducted with nurses in 2 university hospitals in Egypt. The interviews were tape recorded and transcribed. Thematic analysis was conducted by 2 independent investigators. The findings highlighted that nurses did not perceive the benefits of hand hygiene, and that they linked the need to wash hands to a sense of dirtiness. Knowledge of hand hygiene and related products was limited and preference for water and soap was obvious. Environmental constraints, lack of role models and social control were identified as barriers for compliance with hand hygiene. A multi-faceted hand hygiene strategy was developed based on existing cultural concepts valued by the hospital staff.

    The extensive use of insecticides in public health and agriculture sectors is the main reason for development of resistance in fleas associated in domestic rodents. The present work was planned to investigate the insecticidal efficacy of Lambda-cyhalothrin, Chlorpyrifos and Fenitrothion against rat flea (Xenopsylla cheopis) infesting rodent species in Giza Governorate, Egypt. The lethal concentration Lc₅₀ and Lc₉₀ of population percent were obtained from the established regression log concentrate-response lines. Data indicated that the values of lethal concentration (Lc₅₀) were 0.293, 1.725 & 2.328% for Lambda-cyhalothrin, chlorpyrifos and Fenitrothion, respectively. The values of lethal concentration (Lc₉₀) were 0.467, 2.839 & 5.197% for Lambda-cyhalothrin, chlorpyrifos and Fenitrothion, respectively.

    Researchers surveyed the psychological well-being of 795 women of reproductive age from Menoufiya, Egypt. Five years earlier, these women had provided data relevant to their family planning behavior. This analysis links these data sets to investigate the impact of family planning on women's sense of well-being, within the context of beliefs about appropriate gender-related behaviors. Well-being measures are derived for trait and state dimensions. Use of family planning and number of children born within the preceding 5 years predicted state ratings of happiness, and number of children predicted anxious pride. Neither are related to any of the trait ratings. Further, 3 different gender-role attitudes are vital to the explanation of how women define and feel good about themselves.

    The study of two Eocene sections exposed at Wadi Nukhul and Wadi Tayiba in west-central Sinai, Egypt for ostracods yielded diverse fauna. Investigation of the recorded taxa revealed findings of eight new marine ostracod species, one belonging to the family Krithidae, Parakrithe tayibaensis n. sp., three to the family Cytheruridae, Cytheropteron bicostsatum n. sp., Cytheropteron nukhulensis n. sp. and Cytheropteron speijeri n. sp., three to the family Trachyleberididae: Digmocythere centroreticulata n. sp. in subfamily Brachycytherinae and Buntonia bassiounii n. sp. and Buntonia posteroacuta n. sp. in subfamily Buntoniinae, and one, Xestoleberis posterotruncata n. sp., to the family Xestoleberididae. The newly erected species have been described and compared with nearest known and probably related taxa. Their records in the studied sections are stratigraphically confined to the Middle Eocene (Lutetian-Bartonian) interval.

    Field investigations in southern Egypt have yielded Acheulian artifacts in situ in authigenic carbonate deposits (CaCO3-cemented alluvium) along the edges of nowaggraded paleovalleys (Wadi Arid and Wadi Safsaf). Uranium-series dating of 25 carbonate samples from various localities as far apart as 70 kilometers indicates that widespread carbonate deposition occurred about 45, 141 and 212 ka (thousand years ago). Most of the carbonate appears to have been precipitated from groundwater, which suggests that these three episodes of deposition may be related to late Pleistocene humid climates that facilitated human settlement in this now hyperarid region. Carbonate cements from sediments containing Acheulian artifacts provide a minimum age of 212 ka for early occupation of the paleovalleys.

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

  11. Genetic Aspects of Gold Mineralization at Some Occurrences in the Eastern Desert of Egypt

    2012-04-01

    The Eastern Desert of Egypt is well known as a gold-mining area since ancient times, there're more than 95 gold deposits and occurrences spread the whole area covered by the basement rocks of Precambrian age. The basement rocks of the Eastern Desert of Egypt constitute the Nubian Shield that has formed a continuous part of the Arabian-Nubian Shield before the opening of Red Sea (Oligocene-Early Miocene). Commonly, the system of gold-bearing quartz veins in the Eastern Desert is clearly structural controlled related to brittle-ductile shear zones that mostly developed during late deformational stages of the evolution history for basement rocks in the Eastern Desert. This running study principally aims to contribute the mineral resource potential of the gold deposits in Egypt, so particularly Fatira, Gidami and Atalla occurrences have been involved into a comprehensive study based on field, structural, mineralogical, geochemical and genetic investigations. It is intended to better understanding for the characteristics, distribution controls, conditions and age of mineralization in relation to the age of the hosting rocks intrusion to find if there're genetic links between the gold mineralization and the evolution of the host intrusive complex. Several authors suggested that the gold mineralization was related to the intrusion of the (postorogenic) Younger granites. Other authors interpret these deposits as products of hydrothermal activity induced either by metamorphism or cooling effects of early Paleozoic magmatism or as combined metamorphic/magmatic episodes. The prime focus will be directed to the ore itself and the associated hydrothermal alteration zones based on detailed maps and well-distributed samples network and geochemical anomalies distribution. The laboratory studies included microscopic examination (reflecting and transmitting microscopy) to allow for determination of the hosting rocks types and mineralogical changes related to the gold mineralization

    Tick-borne diseases comprise a complex epidemiological and ecological network that connects the vectors, pathogens, and a group of host species. The aim of this study was to identify bacteria from the genus Rickettsia associated with ixodid ticks infesting camels and cows in Egypt. Ticks were collected from 6 different localities: Qina, Giza, Qalet El Nakhl, New Valley, El Arish, and Minufia, from July to October 2008. Species were identified using PCR, followed by sequencing. The gltA and rOmpA genes were used for the initial detection of Rickettsia spp. Further characterization of positive samples utilized primers targeting rOmpB, sca4, and intergenic spacers (mppA-purC, dksA-xerC, and rpmE-tRNA(fMet)). Cows were infested with Hyalomma anatolicum excavatum and Boophilus annulatus. Camels were infested with Hyalomma dromedarii, H. impeltatum, and H. marginatum marginatum. Approximately 57.1% of H. dromedarii ticks collected from Qalet El Nakhl were infected with Rickettsia africae, exhibiting 99.1-100% identity to reference strains. Within H. impeltatum, 26.7% and 73.3% of ticks from El Arish were infected with R. africae and R. aeschlimannii, with 98.3-100% and 97.9-100% identity, respectively. Furthermore, 33.3% of H. marginatum marginatum ticks in Qalet El Nakhl were infected with the same two species as H. impeltatum, demonstrating 99.1-100% and 99.3-100% identity, respectively. By comparing percent identities and phylogenetic relationships, R. africae is identified for the first time in Egypt, in addition to R. aeschlimannii, which exhibits 100% identity with the Stavropol strain in GenBank. In conclusion, the obtained data underscore the medical and veterinary importance of tick-borne rickettsioses, which necessitate further investigation by authorities in Egypt. Moreover, additional characterization of these rickettsial isolates should be performed to designate their strains, using a polyphasic strategy combining genotypic and phenotypic tests, to

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

    Background Tobacco use is a serious public health challenge in North Africa, and health professionals play a vital role in tobacco control. In Egypt, limited data are available on the knowledge and attitudes of health care providers regarding tobacco control policies. Such data are especially relevant due to Egypt’s tobacco control laws, adopted in 2007, prohibiting smoking in hospitals and other public places. This study surveyed 49 senior administrative staff, 267 physicians, 254 nurses, and 109 administrative employees working in El-Kasr El-Aini Hospital in Cairo, assessing their knowledge and attitudes regarding Egypt’s tobacco control laws and barriers to their effective implementation in health care facilities. We also investigated the hospital’s compliance with smoke-free policies. Results The majority (>90%) of the hospital workers knew that exposure to second-hand smoke is harmful to health. Physicians and nurses had a more favorable attitude towards the smoking ban when compared to administrative employees. Hospital staff identified the following barriers to successfully implementing the smoking ban: lax enforcement of tobacco control laws, the lack of penalties for violators, the lack of cessation programs, and the prevalence of smoking among physicians. Conclusions Overall, smoke-free policies were poorly enforced in this large teaching hospital in Cairo, Egypt. Interventions to address the identified barriers to their implementation could include the provision of cessation training and services as well as effective communication programs to educate health care workers at all levels regarding the dangers of second-hand smoke exposure and effective measures for protection.

    This socio-sexual review of Ancient Egyptian society aims to increase awareness that the prevalence of sexually transmitted diseases (STDs) is largely determined by the way a society is structured and how that structure functions. The prevalence of STDs in Ancient Egypt has been found to be low. This state of affairs was maintained for centuries. Although the structure of their society was rigidly hierarchical, Egyptian people made it function in an acceptable way. What might be learned is concerned more with prevention than cure. Whether this has any relevance today is discussed. Images PMID:7635496

    The River Nile is the main source of fresh water in Egypt. Most of Egypt's River Nile water (>85%) originates as precipitation over the Ethiopian highlands and is channeled by the Blue Nile. The construction (years: 2011 to 2017) of the Renaissance Dam (reservoir capacity: 70 x 109m3) on the Blue Nile poses an extreme threat to Egypt's population. If the reservoir was to be filled in 7 years, Egypt will lose (during each of 7 years following dam completion) a minimum of 15 x 109m3 of its annual allocation (55 x 109m3) to reservoir filling (10 x 109m3), evaporation (3.5 x 109m3), and infiltration (1.5 x 109m3). Three solutions are proposed: Solution I takes advantage of the cyclicity of Nile floods and is based on findings from a calibrated (against temporal head data) unconfined 2-dimensional transient groundwater flow model for Lake Nasser and surroundings and a calibrated (against lake levels) surface water model. Models show with time: (1) losses to infiltration will decrease (1975-193: 58.4 109m3; 1993-2001: 43.6 x 109m3) due to silting of Lake bottom and encroachment of excess Lake Nasser water will increase (e.g., 1975-1993: none; 1993-2001: 17 x 109m3). We propose to develop sustainable agricultural in the Western Desert: (1) In high flood years, excess Lake Nasser water (e.g., 1993-2001: 17 x 109m3) is channeled across the plateau bounding (from west) the River Nile valley to artificially recharge the Nubian Sandstone Aquifer System (NSAS) that crops out west of the plateau and, (2) in low flood years, we extract the recharged groundwater. Solution II calls on mining the NSAS at reasonable rates. Using temporal (January 2003 - September 2012) Gravity Recovery and Climate Experiment (GRACE) data we estimate the annual depletion rates at 2 x 109m3 due to artificial extraction (1.5 x 109m3) and natural discharge (0.5 x 109m3). Assuming current GRACE depletion rates, the recoverable groundwater (5,180 x 109m3) will last for 2500 years; if we were to quadruple

    DETECTION OF CRUSTAL STRAINS IN EGYPT USING GPS NETWORKS S.M. Mahmoud National Research Institute of Astronomy and Geophysics (NRIAG), Helwan, Cairo, Egypt. Fax: 202 554 80 20 Email: salahm55@yahoo.com Abstract. Studies of crustal deformation in Egypt started as early as 1983 following the occurrence of Aswan earthquake in 1981. Several publications were published and presented in local and international meetings. On November 14, 1981 an earthquake with magnitude 5.6 occurred at kalabsha fault, 70-Km southwest of Aswan City. This earthquake is considered as an important event as it is located not far from the Aswan High Dam. Therefore, the first program for monitoring crustal deformation has been started in Kalabsha area during the winter of 1983 with the cooperation between the National Research Institute of Astronomy and Geophysics (NRIAG) and the Aswan &High Dam Authority. A local network of 18 terrestrial geodetic points was established at kalabsha area in 1983 in order to monitor the horizontal and vertical crustal movements along Kalabsha fault. The initial measurements were carried out in December 1984. These measurements were repeated twice a year till December 1994.An other terrestrial network were established at seiyal fault, 15 km to the north of kalabsha fault. The initial measurements of seiyal network were carried out in March 1989 and repeated twice a year till August 1992. Analysis of the terrestrial horizontal measurements from both networks for the epoch from December 1984 till December 1994 indicated significant deformations varying from 3x10-6 to 7x10-6. Since the year of 1994 till now, the geodetic observations by means of Space Techniques which known as Global Positioning System (GPS) were applied instead of the Terrestrial ones to cover some other regions of the country. Data adjustment and analysis of the reapted GPS campaigns from the different networks prevailed significant movements which helps in more understanding the geodynamics of

    This paper is a product of the Massachusetts Institute of Technology-Cairo University Health Care Delivery Systems Project which has examined the delivery of health services in Egypt in relation to malnutrition, early childhood mortality, and fertility. Egypt's economic progress since the 1952 Revolution has had only limited effect on high mortality among preschool children, infants and a high rate of population growth. This paper uses governorate data and simple analytical methods. 10% of Egyptian children die in the 1st year of life; subsequent mortality is also extensive in the preschool age children. The crude birthrate remains in the high 30s and overall population growth continues unabated. Early childhood mortality reflects the interplay of malnutrition and infection and population growth is caused by the fact that children, especially males, are considered economic assets. High fertility is a reflection of high mortality to a significant degree. 4 dimensions of development in Egypt are: 1) an urban cluster, 2) poverty, 3) the incidence of women in the paid labor force, 4) development in the rural sector, and 5) population density. Agricultural income increases as women enter the paid labor force and agricultural productivity is weakly related to the practice of women working for pay. Infant mortality in Egypt varies with and is most influenced by population pressures on the land, including urban crowdedness and by the proportion of households living below the poverty line. Female employment adds to family income and affects infant mortality indirectly. Policy implications are: 1) the government must deal with the density factor, 2) it must pursue a development strategy that stimulates productivity and raises the resource base of society, and 3) the government must address infant mortality along with malnutrition and morbidity. The author concludes that: 1) variation in the birth rate is less than variation in the infant mortality rate, 2) mortality and

    It has been uncertain whether the glass produced during the Late Bronze Age (LBA) originated in Egypt or Mesopotamia. Here we present evidence for the production of glass from its raw materials in the eastern Nile Delta during the LBA. Glass was made in workshops that were separate from where the production of objects took place. The initial melting of the raw materials to semi-finished glass was done at temperatures of 900 degrees to 950 degrees C, followed by coloration and ingot production at 1000 degrees to 1100 degrees C.

    We evaluated the use of the renewable ground water resources of the Eastern Desert to develop sustainable agriculture in Upper Egypt, an alternative that could alleviate some of Egypt's dependence on water from the Nile River. Ground water from shallow aquifers in the Eastern Desert of Egypt, near the intersection of Wadi El-Tarfa and the Nile River, was analyzed for chemical compositions, stable isotope ratios, and tritium activities. The ground water has a range in total dissolved solids of 300 to 5000 mg/L. Values of {delta}D and {delta}{sup 18}O range from -10 to +34 %o and -2 to +5.2 %o, respectively, and defines a line having a slope of 5.7 that intersects the meteoric water line at about {delta}D = -15% on a plot of 8D versus {delta}{sup 18}O. These findings indicate that the water might have been derived by a combination of evaporation of and salt addition to regional precipitation. Only one sample could have been derived directly by evaporation and transpiration of modern Nile River water. Salinization of the ground water could have occurred through dissolution of marine aerosol dry fallout, carbonate minerals, gypsum, and other trace evaporitic minerals at and near the ground surface. Tritium activities ranged from 0.04 to 12.9 TU (tritium unite), indicating that all but one of the samples were derived at least partly from precipitation that occurred within the last 45 years. These data indicate that Nubian Aquifer paleowater is not a significant component of the shallow aquifers of this portion of the Eastern Desert. The most likely source of this ground water is sporadic flash flood events yielding locally voluminous recharge that accumulates in coarse sediments and fractured rock beneath alluvial channels. The magnitude of this renewable ground water resource and its potential for supporting sustainable agriculture require further investigation.

    In the current research we report data from two studies that examined rates and characteristics of sleep paralysis (SP) in the general population of Denmark and Egypt. In Study I, individuals from Denmark and Egypt did not differ in age whereas there were more males in the Egyptian sample (47 vs. 64 %); in Study II, individuals from Denmark and Egypt were comparable in terms of age and gender distribution. In Study I we found that significantly fewer individuals had experienced SP in Denmark [25 % (56/223)] than in Egypt [44 % (207/470)] p < .001. In Study II we found that individuals who had experienced at least one lifetime episode of SP from Denmark (n = 58) as compared to those from Egypt (n = 143) reported significantly fewer SP episodes in a lifetime relative to SP experiencers from Egypt (M = 6.0 vs. M = 19.4, p < .001). SP in the Egyptian sample was characterized by high rates of SP (as compared to in Denmark), frequent occurrences (three times that in the Denmark sample), prolonged immobility during SP, and great fear of dying from the experience. In addition, in Egypt, believing SP to be precipitated by the supernatural was associated with fear of the experience and longer SP immobility. Findings are discussed in the context of cultural elaboration and salience theories of SP.

    Optimization of solid waste management systems using operational research methodologies has not yet been applied in any Egyptian governorate. In this paper, a proposed model for a municipal solid waste management system in Port Said, Egypt is presented. It includes the use of the concept of collection stations, which have not yet been used in Egypt. Mixed integer programming is used to model the proposed system and its solution is performed using MPL software V4.2. The results show that the best model would include 27 collection stations of 15-ton daily capacity and 2 collection stations of 10 ton daily capacity. Any transfer of waste between the collection station and the landfill should not occur. Moreover, the flow of the district waste should not be confined to the district collection stations. The cost of the objective function for this solution is 10,122 LE/day (equivalent to 1716 US dollars). After further calculations, the profit generated by the proposed model is 49,655.8 LE/day (equivalent to 8418.23 US dollars). PMID:16055323

    Background Consanguinity has been suggested as a risk factor for psychsoses in some Middle Eastern countries, but adequate control data are unavailable. Our recent studies in Egypt have shown elevated parental consanguinity rates among patients with bipolar I disorder (BP1), compared with controls. We have now extended our analyses to Schizophrenia (SZ) in the same population. Methods A case-control study was conducted at Mansoura University Hospital, Mansoura, Egypt (SZ, n = 75; controls, n = 126, and their available parents). The prevalence of consanguinity was estimated from family history data (‘self report’), followed by DNA analysis using short tandem repeat polymorphisms (STRPs, n = 63) (‘DNA-based’ rates). Results Self reported consanguinity was significantly elevated among the patients (SZ: 46.6%, controls: 19.8%, OR 3.53, 95% CI 1.88, 6.64; p = 0.000058, 1 d.f.). These differences were confirmed using DNA based estimates for coefficients of inbreeding (inbreeding coefficients as means ± standard error, cases: 0.058 ± 0.007, controls: 0.022 ± 0.003). Conclusions Consanguinity rates are signifcantly elevated among Egyptian SZ patients in the Nile delta region. The associations are similar to those observed with BP1 in our earlier study. If replicated, the substantial risk associated with consanguinity raises public health concerns. They may also pave the way for gene mapping studies. PMID:20435442

    Portions of heart, liver, skeletal and diaphragmatic muscles obtained from 150 slaughtered horses at Giza-Zoo abattoir were used for bioassays in mice and cats. T. gondii tachyzoites were isolated successfully from the peritoneal exudates of the inoculated mice 6-8 days post inoculation with pooled horse tissues. Whereas, T. gondii tissue cysts containing bradyzoites were detected in the impression smears of mice brain on the 45th days or more post infection. The oocysts were detected in feces of cats 3-6 days post feeding on horse tissues containing tissue cysts. The oocysts became sporulated within 3-5 days in 2.5% Potassium dichromate. A total of 79 out of 150 horse meat samples were found to be infected with an incidence rate of 52.6 %. This is the first trial for isolation of T. gondii infective stages from horses in Egypt. Moreover, this study pointed out to the high infection rate of T. gondii in horse meat which may be considered as an important source of infection to wild zoo-animals in Egypt and humans in some countries if consumed raw or insufficiently cooked.

    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

    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. PMID:26798844

    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.

They were all observed at the Ain Shams University Specialized Hospital in Cairo, Egypt, during the year 2010. These cases were categorized as 50% proven and 50% probable, with none considered to be possible mucormycosis. The median age of the patients discussed in this report was 50 years (range 22-68 years), of which 80% were male and 20% were female. Uncontrolled diabetes with ketoacidosis was noted in 60% of cases, while 40% of the patients had undergone liver transplantations. Pulmonary mucormycosis was the predominant presentation as it was noted in 80% of cases, but there was only 20% sinus involvement. Members of the genus Lichtheimia were the most common etiologic agents (40% of all cases), whereas Rhizopus ssp. were recovered from 30% of cases, Syncephalastrum spp. in 20%, and 10% of patients were infected with Rhizomucor. Liposomal formulation of amphotericin B (LAMB) was successfully used to treat all the cases described in this report. We concluded that the incidence of mucormycosis was relatively high during the study period in this one-center study and that additional studies looking into the diagnosis and the control of mucormycosis in Egypt are required.

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

    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.

    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. PMID:26798844

    Infectious diseases are important causes of morbidity and mortality globally. Epidemiologically, differences in the patterns of infectious diseases and antimicrobial resistance exist across diverse geographical regions. In this review on infectious diseases in the Arabian Peninsula and Egypt, the epidemiology of tuberculosis, malaria and human immunodeficiency virus (HIV) infections will be addressed. The challenges of the hepatitis C epidemic in Egypt and the epidemiology of this infection across the region will be reviewed. In recent years, we have seen dengue endemicity become established, with major outbreaks in parts of the region. Emerging data also indicate that, across the region, there is an increasing burden of antibiotic resistance, with endemicity in healthcare settings and dissemination into the community. New challenges include the emergence of the Alkhurma haemorrhagic fever virus in Saudi Arabia. The annual Hajj pilgrimage in Saudi Arabia serves as a model for the control of infectious disease in mass gatherings. As most of these countries constantly experience a uniquely dynamic population influx in the form of expatriate workers, tourists, or pilgrims, concerted regional and international collaboration to address these public health concerns in a region that lies at the crossroads for the global spread of infectious pathogens is imperative.

    The Egyptian state was formed prior to the existence of verifiable historical records. Conventional dates for its formation are based on the relative ordering of artefacts. This approach is no longer considered sufficient for cogent historical analysis. Here, we produce an absolute chronology for Early Egypt by combining radiocarbon and archaeological evidence within a Bayesian paradigm. Our data cover the full trajectory of Egyptian state formation and indicate that the process occurred more rapidly than previously thought. We provide a timeline for the First Dynasty of Egypt of generational-scale resolution that concurs with prevailing archaeological analysis and produce a chronometric date for the foundation of Egypt that distinguishes between historical estimates.

    The treasured ancient papyri provide a glimpse into understanding of common concepts and practices in ancient Egypt. The Kahun gynecological papyrus and other texts unveil the traditions of reproduction, conception and delivery. This article addresses the rationale of beliefs and practices of that era. Frequently, the reason for common traditions exercised at the time is based on medical knowledge of female anatomy and physiology during pregnancy. Surprisingly some of the remedies commonly used in ancient Egypt were recently explored and found intriguing. This paper was aimed to look at the reflection of archaic practices and concepts of ancient Egypt by the modern mirror of evidence-based medicine.

    Epidemiological and molecular data on community acquired methicillin resistant Staphylococcus aureus (CA-MRSA) are still scarce in both Egypt and Saudi Arabia. There is almost no data regarding methicillin resistant Staphylococcus aureus (MRSA) prevalence in both countries. This study was conducted to investigate the prevalence and molecular epidemiology of S. aureus and MRSA nasal carriage among outpatients attending primary health care centers in two big cities in both countries. A total of 206 nasal swabs were obtained, 103 swabs from each country. S. aureus isolates were characterized by antibiotic susceptibility, presence of mecA and PVL genes, SCCmec-typing and spa typing, the corresponding Multi locus sequence typing clonal complex was assigned for each spa type based on Ridom StaphType database. MRSA was detected in 32% of the Egyptian outpatients while it was found in 25% of the Saudi Arabian outpatients. All MRSA isolates belonged to SCCmec type V and IVa, where some isolates in Saudi Arabia remained nontypeable. Surprisingly PVL(+) isolates were low in frequency: 15% of MRSA Egyptian isolates and 12% of MRSA isolates in Saudi Arabia. Two novel spa types were detected t11839 in Egypt, and t11841 in Saudi Arabia. We found 8 spa types among 20 isolates from Egypt, and 12 spa types out of 15 isolates from Saudi Arabia. Only two spa types t008 and t223 coexisted in both countries. Four clonal complexes (CC5, CC8, CC22, and CC80) were identified in both Egypt and Saudi Arabia. However, the data collected lacked a representation of isolates from different parts of each country as only one health center from each country was included, it still partially illustrates the CA-MRSA situation in both countries. In conclusion a set of control measures is required to prevent further increase in MRSA prevalence.

  4. All Eyes on Egypt: Islam and the Medical Use of Dead Bodies Amidst Cairo's Political Unrest.

    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.

    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.

    The mining work at El-Gedida iron mine, El-Bahariya Oasis, in the Western Desert of Egypt extracts commercial iron ore deposits without attention paid to the large glauconite deposits overlying these iron ore deposits. For this reason, the present paper aims at evaluating and attracting the attention to these glauconite deposits as alternative potassium fertilizers. The study was achieved by investigating mineralogical, physical and chemical properties of the green deposits. Mineralogical and physical properties involved the determination of glauconite pellets content in different grain size fractions relative to impurities and the analysis of the percentage of clay matrix and grain size distribution. Different pre-treatment strategies and methods including comminution, sieving, magnetic separation, and X-ray diffraction were used for investigating those mineralogical and physical properties. On the other hand, chemical analyses included potassium content, heavy metal concentrations, and pH and salinity measurements. The major elements and trace elements were measured using ICP-OES and the pH was measured using a pH conductometer. Moreover, this study investigated the nature of grain boundaries and the effect of sieving on glauconite beneficiation. Results of this study suggest that El-Gedida glauconite deposits are mineralogically, physically and chemically suitable for exploitation and can be beneficiated for use as an alternative potassium fertilizer.

While it is debatable whether the story of a king-physician is a fact or just a legend, it is clear that ancient Egyptian medicine developed around the time of his reign. The fortunate combination of earlier medical observations, the development of script, and favorable social conditions made the dawn of ancient Egypt also the dawn of medicine.

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.

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.

    Acrolein is a dual-purpose chemical effective against both submersed weeds and snails, and it may therefore be of significance in bilharziasis control. During trials in the Egypt-49-project area in 1962, it was effective in clearing heavy mats of the major submersed aquatic weed Potamogeton crispus from irrigation canals. The resurgence of snails to pretreatment levels was delayed by 8-12 months, and submersed weeds did not reappear until 8 months after treatment. In phytotoxicity tests on local crops, it was found that the concentration of acrolein required for destroying submersed weeds (20-25 ppm) had no adverse effect on the crops. The field tests showed that it is important to have complete control of the water during the period of application. PMID:14310913

    Sex is a basic human need, common to all people at all times. It is evident that the ancient Egyptians were real human beings, not only a people who built massive pyramids and made mummies of their dead. The ancient Egyptians had a rich and varied sexual life, which they found an opportunity to describe in words and pictures. As in the other early primitive civilizations, erotic matters were of prime importance and became an integral part of life. In Pharaonic times, the Egyptians described impotence and recorded several methods to increase the sexual power. In the present paper, we will shed light on some aspects of the sexual life in ancient Egypt that may be interesting to the urologists, including ancient Egyptian concepts of sex and erotic matters, their own way of treatment of impotence and Min, the Egyptian fertility God.

The population of six selected areas (St Catherines, Nuweiba, Abu Rudeis, Ras Sudr, El Tor and Abu Zenima) were subdivided into Bedouin, urban and mixed populations. A questionnaire-based interview was conducted showing that the consanguinity rate in this region is 37.5%, with the highest rate recorded in Abu Rudeis (52.3%) and lowest rate in Nuweiba (24.1%). Consanguinity was significantly higher among the Bedouin population compared with the urban population in Abu Rudeis, Ras Sudr, El Tor and Abu Zenima, while in St Catherines and Nuweiba there was no statistically significant difference. Among consanguineous couples, 5%, 60% and 35% were double first cousins, first cousins and second cousins respectively. The mean inbreeding coefficient α of the studied population was 0.01845.

    The Shuttle Multispectral Infrared Radiometer (SMIRR) is a spectroradiometer covering the region from 0.5 to 2.5 ??m in 10 channels that acquired data from spots 100 m in diameter along the subspacecraft ground track. It was flown aboard the second flight of the space shuttle Columbia, November 12-14, 1981. Data collected during orbit 16 over southern Egypt show that carbonate rocks, kaolinite, and possibly montmorillonite can be identified by their SMIRR spectral signatures and limited knowledge of the lithologic units present. Detailed analysis of SMIRR data for this area indicates that calcite, kaolinite, and montmorillonite rocks give rise to absorption features that result in characteristic 10 channel spectra. ?? 1983.

The paper provides an assessment of traffic safety conditions for rural roads in Egypt. This is done through a three-step procedure. First, deaths per million vehicle kilometers are obtained and compared for Egypt, three other Arab countries and six of the G-7 countries. Egypt stands as having a significantly high rate of deaths per 100 million vehicle kilometers. This is followed by compiling available traffic and accident data for five main rural roads in Egypt over a 10-year period (1990-1999). These are used to compute and compare 13 traffic safety indicators for these roads. The third step for assessing traffic safety for rural roads in Egypt is concerned with presenting a detailed analysis of accident causes. The paper moves on to develop a number of statistical models that can be used in the prediction of the expected number of accidents, injuries, fatalities and casualties on the rural roads in Egypt. Time series data of traffic and accidents, over a 10 years period for the considered roads, is utilized in the calibration of these predictive models. Several functional forms are explored and tested in the calibration process. Before proceeding to the development of these models three ANOVA statistical tests are conducted to establish whether there are any significant differences in the data used for models' calibration as a result of differences among the considered five roads.

    AIM To detect the incidence of retinopathy of prematurity (ROP) in a tertiary referral neonatal intensive care unit in upper Egypt and to describe the obstacles faced during implementing the screening protocol for the first time. METHODS Consecutive infants were enrolled at birth and screened for ROP. We used the UK ROP guideline (May 2008) for infant selection, follow up and treatment. Repeat examinations were performed until retinal vascularisation was complete. RESULTS Fifty-two infants were enrolled: 24 males and 28 females. Mean gestational age was 31.3wk (±2.8 SD) and mean birth weight was 1234.6 g (±221.1 SD). Incidence of ROP was 36.5% (stages 1, 2, 3 and 4a were 9.6%, 9.6%, 15.4% and 1.9% respectively), no stages 4b or 5 were found in this series. Six infants (11.5%) died during screening without ROP, 25 infants (48.1%) were discharged from screening with retinal vascularisation reaching zone III, 5 infants (9.6%) were treated with indirect diode with or without additional cryotherapy and 16 infants (30.8%) were lost to follow up. In this series gestational age rather than birth weight was found significantly correlated and predictive (P<0.05) with ROP stages. CONCLUSION ROP in a single site in Upper Egypt appears to have comparable incidence to other areas worldwide. The main screening obstacle was missing cases due to the absence of a national ROP screening protocol. PMID:26949647

    The present drinking water purification system in Egypt uses surface water as a raw water supply without a preliminary 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 filtering effectiveness and produce the trihalomethane (THM) species as a chlorination by-product. The Ismailia Canal represents the most distal downstream of the main Nile River. 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 industrial zone along the upstream course of the canal enriches the canal water with high concentrations of heavy metals. The obtained results indicate that the canal gains up to 24.06x10(6) m3 of water from the surrounding shallow aquifer during the closing period of the High Dam gates, while during the rest of the year, the canal acts as an influent stream losing about 99.6x10(6) m3 of its water budget. The reduction of total organic carbon (TOC) and suspended particulate matters (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.

    Although hemodialysis is the main modaility of treatment of end-stage renal disease, no practice guidelines are available in Egypt. Applying international guidelines for hemodialysis would not be suitable or feasible, because of different health system and lack of resources. The aim of this project was the development of evidence- and consensus-based clinical practice guidelines for hemodialysis in Egypt. The Egyptian guidelines were adopted from the standards developed by The College of Physicians and Surgeons of Alberta (Canada), The National Kidney Foundation (USA), The Clinical Standards Board for Scotland (Scotland), and The College of Physicians and Surgeons of Ontario (Canada). In addition, the guidelines published in Oxford Handbook of Dialysis were reviewed. Thereafter, a panel of Egyptian experts in the field of nephrology and hemodialysis was selected and invited to participate in this project. The Delphi technique was applied to build up the consensus among the experts on the formulated guidelines. The final version of the Egyptian Hemodialysis Practice Guidelines included five main sections; personnel, patient care practices, infection prevention and control, facility, and documentation/records. A consensus on practice guidelines for hemodialysis has been successfully produced and is supported by levels of evidence. The 12 Egyptian experts who participated in the Delphi technique and the reviewers assured the completeness and acceptability of the developed practice guidelines. Also, including experts from the university hospitals together with the Directorates of Cairo and Giza Health Affairs of the Egyptian Ministry of Health (MOH) avoided conflicts between clinical recommendations and feasible application in the MOH hemodialysis facilities.

    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

    This paper highlights the impacts of soil sealing on the agricultural soils in Nile Delta using remote sensing and GIS. The current work focuses on two aims. The first aim is to evaluate soil productivity lost to urban sprawl, which is a significant cause of soil sealing in Nile Delta. The second aim is to evaluate the Land Use and Land Cover Changes (LU LC) from 2001 to 2013 in El-Gharbia governorate as a case study. Three temporal data sets of images from two different sensors: Landsat 7 Enhanced Thematic Mapper (ETM+) with 30 m resolution acquired in 2001 and Landsat 8 acquired in 2013 with 30 m resolution, and Egypt sat acquired in 2010 with 7.8 m resolution, consequently were used. Four different supervised classification techniques (Maximum Likelihood (ML), Minimum Distance, Neural Networks (NN); and Support Vector Machine (SVM) were applied to monitor the changes of LULC in the investigated area. The results showed that the agricultural soils of the investigated area are characterized by high soil productivity depending on its chemical and physical properties. During 2010-2013, soil sealing took place on 1397 ha from the study area which characterized by soil productivity classes ranging between I and II. It is expected that the urban sprawl will be increased to 12.4% by 2020 from the study area, which means that additional 3400 ha of productive soils will be lost from agriculture. However, population growth is the most significant factor effecting urban sprawl in Nile Delta.

    The aim of this study was to provide the first detailed insight into the population structure of Staphylococcus aureus in one modern dairy farm (Gamasa) and several household cows and buffaloes in Dakahlia Governorate, Egypt. Eight hundred seventy-two quarter milk samples of 218 dairy cattle and buffaloes with clinical and subclinical mastitis were investigated. Bacteria were identified using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry, and staphylococci were further characterized by DNA sequencing of 16S rRNA genes and microarray analysis. Staphylococcus aureus was present in 5.6% of all collected samples, whereas methicillin-resistant S. aureus (MRSA) represented 24.5% of all identified S. aureus (12/49). Six clonal complexes (CC) of S. aureus were detected. Staphylococcus aureus CC398 (ST291/813)-MSSA (methicillin-susceptible S. aureus) was identified frequently in the Gamasa farm in addition to a few CC5-MRSA-V isolates. However, a small number of different isolates of S. aureus were found in household cattle and buffaloes harboring different CC. The presence of these genotypes of S. aureus in milk might indicate a public health hazard, because all of these CC have previously been isolated from human patients. Thus, a recommendation was given to the owner of the dairy farm to review the hygiene regimen on the farm. In perspective, further investigation regarding S. aureus screening of all lactating cows and personnel on the farm is warranted.

    The Egypt Exploration Society Theban Harbours and Waterscapes Survey (THaWS) works in the area around modern Luxor (Egypt), and investigates the extent to which the Egyptians manipulated the Nile and floodplain through canal and basin construction. A current focus of the project is to understand the relationship between the floodplain and a series of temples on the West Bank. A longstanding puzzle on the West Bank is why the temple of Amenhotep III (1390-1352 BCE) is not located in the same area as all the others. While 19 kings of the Egyptian New Kingdom (1550-1070 BCE) built their temples on the toe-slope of the limestone cliffs fronting onto the edge of the modern alluvium, Amenhotep's sits entirely on the modern floodplain. Egyptologists have suggested this was done to allow the inundation of the Nile to wash into the temple, symbolising and recreating the essential Egyptian cosmogony of the primeval mound. However, was it possible that a period of low Nile discharge enabled him to build on the alluvium whilst keeping the temple dry from the Nile floods? The project is testing this hypothesis through an interdisciplinary approach which provides focussed information on the development of the floodplain over historic time periods. It combines geophysical survey (Electrical Resistivity Tomography, Ground Penetrating Radar and magnetometry) with geoarchaeology using an Eijkelkamp hand auger and gouge auger with facies being dated using the stratigraphic sequence of ceramic fragments within them. Two fieldwork seasons have been carried out to date (Graham et al. 2012, 2013). Calcareous palaeosols c. 4m below the surface have been identified in three separate augers across a distance of 3 km on the West Bank floodplain, suggesting a period of low inundation levels / drought. At one of the locations an ancient surface appears to lie 0.3-0.4m above the calcisol. Ceramic fragments from this unit tentatively indicate a New Kingdom date. The strontium isotope record from

    The present study was planned to investigate the prevalence of Sarcocystis spp. among slaughtered water buffaloes (Bubalus bubalis) at Alexandria province, Egypt. Three hundred blood samples were collected from slaughtered buffaloes (5-7 years old). Two techniques were used to evaluate the seroprevalence of Sarcocystis spp., enzyme-linked immunosorbent assay (ELISA) and indirect haemagglutination assay (IHA). It was revealed that 203 (67.6 %) and 191 (63.6 %) of the tested serum samples were seropositive to Sarcocystis spp. by ELISA and IHA, respectively. The results of sensitivity and specificity of IHA relative to ELISA were 94 and 100 %, respectively. For molecular characterization of inter- and intra-species genetic polymorphism within Egyptian isolates of Sarcocystis spp. of water buffaloes, polymerase chain reaction (PCR) and polymerase chain reaction-restriction length polymorphisms (PCR-RFLPs) were performed on four macroscopic isolates. The isolates represented two different geographical regions of Egypt, Alexandria and Assuit provinces. Alexandria isolates (large and small-sized cyst of the same host) and Assuit isolates (large and small-sized cyst of the same host) were used. The 18S rDNA of the macroscopic cysts were characterized, in tandem, by four restriction endonucleases, RsaI, MboI, SspI and DraI. RsaI and MboI enzymes did not show any restriction sites for all isolates, leaving the amplified fragments without cutting. SspI showed two fragments in Alexandria and Assuit small-sized isolates cut by the enzyme at 600-700-bp fragments, while Alexandria and Assuit large-sized cysts amplicons were not digested by this enzyme. The fourth enzyme, DraI, cut the PCR product of Alexandria large-sized cysts into two fragments (420-780 bp), while Assuit large-sized amplicon was not cut. It could be concluded that there was a far distance between the two local isolates (small and large sized), but there were no differences between the large-sized isolates.

  13. Wintertime surface temperature in Egypt in relation to the associated atmospheric circulation

    Mean wintertime temperatures (December, January, February) recorded during the period 1905-2000 at 18 weather stations distributed across Egypt were analysed to reveal spatial and temporal patterns of long-term trends. The relationship between winter atmospheric circulation indices and winter temperature in Egypt is examined using correlation analysis. The atmospheric circulation is represented by four indices: the well-known El Niño-southern oscillation (ENSO), North Atlantic oscillation (NAO) index, East Atlantic-West Russia (EAWR) index, and East Atlantic (EA) index.Surface temperature is a stable climatic element whose coefficient of variation (COV) is lower during winter. A statistically significant relation between COV and latitude indicates that stations in the south, Upper Egypt, are more variable than stations in the north, Lower Egypt. Increasing and decreasing winter surface temperature trends were found. In general, wintertime temperature has increased (warming) at most stations. Decreasing trends (cooling) are observed mainly over Upper Egypt. The upward trends in mean winter temperature during the 1910s-30s, mid 1970s, and early 1980s-2000 and the downward trends during the 1940s and 1960s are prominent features of the temporal distributions. The warming period that occurred early in the century may be explained by changes in circulation. Striking upward trends are most remarkable during the last 20 years. This could be attributed not only to human activities, but also to atmospheric circulation changes. No detectable connection between Egypt temperature and either ENSO or EA index was found during winter. A statistically significant negative relationship between winter temperature and winter NAO index can be observed. The NAO index is more dominant in determining winter temperature than ENSO circulation. A significantly stronger negative relationship between temperature over Egypt and the winter EAWR index values is detected.

    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 long-term endemicity of H5N1 and the recent emergence of H9N2 in poultry call attention to the need for unravelling the epidemiology, ecology and highly diverse gene pool of influenza A virus (IAV) in Egypt which is the aim of this review. Isolation of a considerable number of IAV subtypes from several avian and mammalian hosts was described. Co-infections of poultry with H5N1 and H9N2 and subclinical infections of pigs and humans with H1N1 and H5N1 may raise the potential for the reassortment of these viruses. Moreover, the adjustment of IAV genomes, particularly H5N1, to optimize their evolution toward efficient transmission in human is progressing in Egypt. Understanding the present situation of influenza viruses in Egypt will help in the control of the disease and can potentially prevent a possible pandemic. PMID:25635701

    The quantitative measurement of radionuclides ((226)Ra, (232)Th and (40)K) in some roofing tile materials (granite, alabaster, marble, traditional and advanced ceramic) used in Upper Egypt is presented in this paper. Measurements were done by using gamma spectrometry (NaI (Tl) 3" × 3"). The values of concentration of natural radionuclides were in the following ranges: 12-78.9 Bq kg(-1) for (226)Ra, 8.4-113.1 Bq kg(-1) for (232)Th and 94.9-509 Bq kg(-1)for (40)K. The activity concentration index (I), the specific dose rates indoors ( ) and the annual effective dose (DE) due to gamma radiation were calculated for each investigated sample. The lowest value of I is 0.19 for alabaster, while the highest one is 0.88 for traditional and advanced ceramic. The ranges of DE are between 0.03 and 0.13 mSv, it is below the maximal permitted values, so that the examined materials could be used as roofing tiles in the construction of new buildings.

The results showed relatively moderate radionuclide concentrations for all samples except granite, which showed extremely high concentrations of 78.75 ± 2.36, 2.82 ± 0.11 and 2.37 ± 0.07 kBq kg⁻¹ for ²²⁶Ra, ²³²Th and ⁴⁰K, respectively. The radiological hazard indexes of radium equivalent activity (Raeq), external hazard index (Hex) and internal hazard index (Hin), due to the presence of those radionuclides in the investigated building materials, were calculated. The released radon from the selected samples was measured using the AlphaGUARD radon monitor in order to use its value to calculate the radon emanation coefficient and the radon exhalation rate. The alpha equivalent dose (dose from indoor radon generated from building materials) was calculated using the measured values of the radium concentration and the radon emanation coefficient.

    The shallow-water siliciclastics and carbonates of the Miocene sediments in the Cairo-Suez District, Egypt represent an epiric ramp. The facies are characterized by stacked high-frequency cycles with restricted ramp to shoal margin sequences. Based on an extensive micro- and biofacies documentation, six lithofacies associations were defined and their respective depositional environments were interpreted. A sequence-stratigraphic analysis was carried out by integrating lithostratigraphic marker beds, facies relationships, stratigraphic cycles, and biostratigraphy. The investigated sections were subdivided into three third-order sequences, named S1, S2 and S3. S1, is interpreted to correspond to the Late Burdigalian stage (18-16.38 My), S2 corresponds to the Late Burdigalian-Early Langhian stage (16.38-14.78 My), and S3 represents the Late Langhain-Early Serravallian stage (14.78-13.66 My). Each of the three sequences was further subdivided into fourth order cycle sets and fifth-order cycles.

    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.

    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 106 and 107 cultivable sulfate-reducing bacteria ml−1 and showed sulfate reduction rates between 1,000 and 2,200 nmol ml−1 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 in variable densities of 104 to 106 cells ml−1. A Desulfonema-related, diurnally migrating bacterium was detected with PCR and denaturing gradient gel electrophoresis within and below the oxic surface layer. Facultative aerobic respiration, filamentous morphology, motility, diurnal migration, 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 accounted for 7 to 8% of the total photosynthetic CO2 demand of the mat.

    An asymmetrical carbonate platform margin to basin transect has been investigated in the Upper Campanian-Maastrichtian succession of the Galala Mountains, northern Egypt. Identification of systems tracts and their lateral correlation was possible in slope sections only, whereas the monotonous chalk-marl alternations of the basinal sections could not be subdivided with respect to sequence stratigraphic terminology. The platform asymmetry is expressed by varying large-scale depositional architectures exhibiting a rimmed platform with a sigmoidal slope curvature in south-easterly dip-sections and a ramp with a linear slope curvature in south-westerly dip-sections. The rimmed platform is subdivided into a gentle upper slope and a steep lower slope. The platform formed as a result of the initial topography that was controlled by the tectonic uplift of the Northern Galala/Wadi Araba Syrian Arc structure. The calculated angles of the steep lower slope of the rimmed part range from 5 to 8°, whereas the ramp part has an angle of less than 0.1°.

    This study investigated the microbial causes of diarrheal disease among U.S. troops deployed near Alexandria, Egypt, during October 1995. Bacterial causes associated with 19 cases of diarrhea included: enterotoxigenic Escherichia coli (ETEC), 42% (21% heat-stable, 11% heat-labile, and 11% heat-stable/ heat-labile producers); enteropathogenic E. coli (5.3%); and enteroadherent E. coli (42%). Four cases of diarrhea were associated with enteroaggregative E. coli based on probe analysis for enteroaggregative heat-stable enterotoxin 1. Protozoan causes included; Entamoeba histolytica (11%), E. hartmanni (5%), E. nana (5%), Blastocystis hominis (5%), Chilomastix mesnili (11%), Dientamoeba fragilis (5%), Entamoeba coli (5%), and Cryptosporidium (5%). Shigella, Aeromonas, Plesiomonas, Vibrio, Campylobacter, and Salmonella were not detected. Of the eight ETEC cases, one was colonization factor antigen (CFA)/I only, one was both CFA/I and CFA/III, three were CFA/II, two were CFA/IV, and two were CFA-negative. Antibiograms of the ETEC and enteroadherent E. coli strains showed that all isolates were susceptible to norfloxacin, ciprofloxacin, and nalidixic acid but resistant to ampicillin, tetracycline, chloramphenicol, and sulfamethoxazole.

    The radioactivity levels are poorly studied in non-coastal arid regions. For this reason, 38 locations covering an area of about 350 km(2) in northeast Sinai, Egypt, were investigated by γ-ray spectroscopy. Moderately significant correlations among (238)U, (234)Th, and (226)Ra isotopes and low significant correlations between the concentrations of (238)U-series and (232)Th in sand were obtained. No evidence of correlation was found between the concentrations of radioisotopes and pH, grain size, total organic matter content, bicarbonate or calcium carbonate concentrations of the sand samples. The mean values of soil-to-plant transfer factor were 0.15, 0.18, 1.52 and 0.74 for (226)Ra, (232)Th, (40)K, and (137)Cs, respectively. The range of concentrations of (226)Ra,( 232)Th, and (40)K in water samples collected from five wells were<0.4-0.16,<0.4-0.13, and<0.15-1.62 Bq l(-1), respectively. The mean absorbed dose rate in outdoor air at a height of 1 m above the ground surface for the sand samples was 19.4 nGy h(-1). The Ra(eq) activities of the sands are lower than the recommended maximum value of 370 Bq kg(-1) criterion limit for building materials.

    Food-borne pathogens are of high concern for public health and food safety. Staphylococcus aureus food poisoning is one of the most economically devastating types of food poisoning globally. The purpose of this study was to detect staphylococcal classical enterotoxins (SEs) in processed beef from Kingdom of Saudi Arabia (KSA) and Egypt. In the present investigation a total of 250 random processed meat samples (50 each of minced meat, beef burger, beef sausage, beef kofta and beef luncheon) were collected from different super markets in the study area. Using conventional cultural methods, samples were cultured for isolation and identification of S. aureus. Multiplex PCR was used to detect SEs of the classical type SEA, SEB, SEC and SED from isolates. The percentage presence of S. aureus in minced meat, beef burger, beef sausage, beef kofta and beef luncheon was 38%, 22%, 30%, 32% and 12%, respectively. Multiplex PCR indicated that all examined samples contain different types of classical staphylococcal enterotoxins and only minced meat samples contained all four types of toxins. Multiplex PCR is efficient in detection of SEs from food and may be used in tracing of toxins to promote food hygiene. Implications of contamination of processed meat to food hygiene in the study area are highlighted. PMID:27088066

    Groundwater in Upper Egypt especially in Assiut Governorate is considered the second source of fresh water and used for drinking, agriculture, domestic and industrial purposes. Unfortunately, it is characterized by high concentrations of iron and manganese ions. The study aimed at synthesizing zeolite-4A from kaolinite for removing the excess iron and manganese ions from Assiut Governorate groundwater wells. Therefor, the kaolinite was hydrothermally treated through the metakaolinization and zeolitization processes to produce crystalline zeolite-4A. The chemical composition of crystalline zeolite-4A and its morphology were then characterized using X-ray diffraction (XRD) and scanning electron microscopy (SEM). Then the column experiments were conducted to study the performance of crystalline salt-4A as ion exchange and investigate their operating parameters and regeneration conditions. Thomas and Yoon-Nelson models were applied to predict adsorption capacity and the time required for 50 % breakthrough curves. The effects of initial concentrations of 600 and 1000 mg L-1 for Fe2+ and Mn2+, feed flow rate of 10-30 ml/min, and height range of 0.4-1.5 cm on the breakthrough behavior of the adsorption system were determined. The obtained results indicated that the synthesized zeolite-A4 can remove iron and manganese ions from groundwater to the permissible limit according to the standards drinking water law.

    This study aims to investigate groundwater geochemical characteristics, and to assess the effects of groundwater contamination in northwest Sinai, Egypt. A geographic information system, geochemical modeling, and statistical analyses tools were used. Twenty-five groundwater samples from a Quaternary aquifer were sampled. These water samples were analyzed for major, minor, and trace elements. The results of this study contribute to a better understanding of the hydrochemical characteristic as well as the anthropogenic processes of groundwater pollution. On the basis of these analyses, the geochemical parameters and the anomalous concentration of different elements enable the characterization of salinity sources of the brackish waters and the suspected sources of polluted water. Pollution sources are represented by waste disposal and agricultural activities as well as the probable upward leakage of highly saline water from the deeper aquifers and the saltwater intrusion. Pollution risk is high when the depth of the water table is shallow (0.3 to 15.0 m) and the aquifer has high hydraulic conductivity and poor matrix buffering capacity.

    Bladder cancer is the most common malignancy among Egyptian males and previously has been attributed to Schistosoma infection, a major risk factor for squamous cell carcinoma (SCC). Recently, transitional cell carcinoma (TCC) incidence has been increasing while SCC has declined. To investigate this shift, we analyzed the geographical patterns of all bladder cancers cases recorded in Egypt's Gharbiah Population-Based Cancer Registry from 1999 through 2002. Data on tumor grade, stage, and morphology, as well as smoking, community of residence, age and sex, were collected on 1209 bladder cancer cases. Age-adjusted incidence rates were calculated for males, females, and the total population for the eight administrative Districts and 316 communities in Gharbiah. Incidence Rate Ratios (IRR) and 95% confidence intervals (CI) were computed using Poisson Regression. The male age-adjusted incidence rate (IR) in Gharbiah Province was 13.65/100,000 person years (PY). The District of Kotour had the highest age-adjusted IR 28.96/100,000 among males. The District of Kotour also had the highest IRR among all Districts, IRR=2.15 95% CI (1.72, 2.70). Kotour's capital city had the highest bladder cancer incidence among the 316 communities (IR=73.11/100,000 PY). Future studies on sources and types of environmental pollution and exposures in relation to the spatial patterns of bladder cancer, particularly in Kotour District, may improve our understating of risk factors for bladder cancer in the region.

    In this study, we have investigated the indoor environmental corrosion of Ag-based alloys after long-term exposure in a showcase of an exhibition room and in the open atmosphere at the Egyptian Museum of Cairo (Egypt). In order to simulate the corrosion processes that occur at the surface of archaeological artefacts, Ag-based alloys with chemical composition, metallurgical features and micro-chemical structure similar to those of ancient alloys have been purposely produced as sacrificial reference samples. Our findings show that corrosion phenomena on alloy surface are mainly caused by environmental sulphur and chlorine containing species that react in different ways depending on the exhibition conditions and on the alloy composition. This approach allows to identify the degradation agents and mechanisms that really take place at the surface of objects similar to ancient artefacts without the necessity of sampling them. Moreover, it is possible to get useful indications for the safe storage or exhibition of silver archaeological artefacts, their cleaning and conservation.

    The quantitative measurement of radionuclides ((226)Ra, (232)Th and (40)K) in some roofing tile materials (granite, alabaster, marble, traditional and advanced ceramic) used in Upper Egypt is presented in this paper. Measurements were done by using gamma spectrometry (NaI (Tl) 3" × 3"). The values of concentration of natural radionuclides were in the following ranges: 12-78.9 Bq kg(-1) for (226)Ra, 8.4-113.1 Bq kg(-1) for (232)Th and 94.9-509 Bq kg(-1)for (40)K. The activity concentration index (I), the specific dose rates indoors ( ) and the annual effective dose (DE) due to gamma radiation were calculated for each investigated sample. The lowest value of I is 0.19 for alabaster, while the highest one is 0.88 for traditional and advanced ceramic. The ranges of DE are between 0.03 and 0.13 mSv, it is below the maximal permitted values, so that the examined materials could be used as roofing tiles in the construction of new buildings.

    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

    Studies of crustal deformation in Egypt started as early as 1983 following the occurrence of Aswan earthquake in 1981. Several publications were published and presented in local and international meetings. on November 14, 1981 an earthquake with magnitude 5.6 occurred at kalabsha fault, 70-Km southwest of Aswan City. This earthquake is considered as an important event as it is located not far from the Aswan High Dam. Therefore, the first program for monitoring crustal deformation has been started in Kalabsha area during the winter of 1983 with the cooperation between the National Research Institute of Astronomy and Geophysics (NRIAG) and the Aswan &High Dam Authority. A local network of 18 terrestrial geodetic points was established at kalabsha area in 1983 in order to monitor the horizontal and vertical crustal movements along Kalabsha fault. The initial measurements were carried out in December 1984. These measurements were repeated twice a year till December 1994.An other terrestrial network were established at seiyal fault, 15 km to the north of kalabsha fault. The initial measurements of seiyal network were carried out in March 1989 and repeated twice a year till August 1992. Analysis of the terrestrial horizontal measurements from both networks for the epoch from December 1984 till December 1994 indicated significant deformations varying from 3x10-6 to 7x10-6. Since the year of 1994 till now, the geodetic observations by means of Space Techniques which known as Global Positioning System (GPS) were applied instead of the Terrestrial ones to cover some other regions of the country. Data adjustment and analysis of the reapted GPS campaigns from the different networks prevailed significant movements which helps in more understanding the geodynamics of these regions and in creating seismic hazard assessments. In this paper, the main characteristics of the seismotectonics of Egypt, which are necessary to a reliable evaluation of the seismic risk, are discussed. The

  18. 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

    This radar image shows the area west of the Nile River near Cairo, Egypt. The Nile River is the dark band along the right side of the image and it flows approximately due North from the bottom to the right. The boundary between dense urbanization and the desert can be clearly seen between the bright and dark areas in the center of the image. This boundary represents the approximate extent of yearly Nile flooding which played an important part in determining where people lived in ancient Egypt. This land usage pattern persists to this day. The pyramids at Giza appear as three bright triangles aligned with the image top just at the boundary of the urbanized area. They are also shown enlarged in the inset box in the top left of the image. The Great Pyramid of Khufu (Cheops in Greek) is the northern most of the three Giza pyramids. The side-looking radar illuminates the scene from the top, the two sides of the pyramids facing the radar reflect most of the energy back to the antenna and appear radar bright; the two sides away from the radar reflect less energy back and appear dark Two additional pyramids can be seen left of center in the lower portion of the image. The modern development in the desert on the left side of the image is the Sixth of October City, an area of factories and residences started by Anwar Sadat to relieve urban crowding. The image was taken on April 19, 1994 by the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) aboard the shuttle Endeavour. SIR-C/X-SAR, a joint mission of the German, Italian and the United States space agencies, is part of NASA's Mission to Planet Earth. The image is centered on latitude 29.72 degrees North latitude and 30.83 degrees East longitude. The area shown is approximately 20 kilometers by 30 kilometers. The colors in the image are assigned to different frequencies and polarizations of the radar as follows: red is L-band horizontally transmitted, horizontally received; green is C

    Changes in the environment often cause changes in disease transmission. Land use change especially urbanization can have a huge impact on transmission of vector-borne diseases. This study investigated the effect of urban development on the abundance of sand flies, in an old endemic focus of infantile visceral leishmaniasis in the north coast of Egypt. Sand fly abundance obtained in this study was compared to those obtained in 1984. In context remote sensing techniques are used to identify landscape features that might have influenced the spatial distribution of the sand fly vector in the area. In 2005, sand flies were completely absent from El Agamy. Sand fly habitat in El Agamy entirely changed and was replaced by urban settlements. Through the analysis of satellite imagery taken before and after, land use/land cover modification together with entomological data, the factors underlying the bionomics of sand flies are discussed.

    The present work deals with the radioactivity of granites in Gable Gattar II, which is located in the north eastern desert of Egypt. Fifty samples from the area of Gable Gattar II were investigated. The radionuclides of the samples, in Bq/kg, have been measured using a hyper-pure germanium spectrometer. The dose obtained for 238U and 232Th ranged from 165 +/- 5 to 27,851 +/- 836 and 71 +/- 2 to 274 +/- 8 Bq/kg, respectively. The dose of 40K only changes slightly. To assess the radiological hazard of the natural radioactivity in the samples, the radium equivalent activity, the absorbed dose rate and the external hazard index were calculated. This study provides a baseline map of radioactivity background levels in the Egyptian environment and will be used as reference information to assess any changes in the radioactive background level due to geological processes. The Gable Gattar granite, from uranium mineralization, has high economic potential.

Methods: A case–control study, 87 workers as exposed and 45 as control subjects. Questionnaire, clinical examination, and laboratory investigations: liver functions, matrix metalloproteinase-9, immunoglobulins G and E, and anti-liver kidney microsomal antibody. Results: In the exposed workers, mean levels of liver functions, matrix metalloproteinase-9 (MMP-9), and IgG and IgE were significantly higher. In the silicotic subgroup the mean level of GGT was almost twice the level in the non-silicotic subjects. Logistic regression showed that abnormal GGT and ALT were associated with production workers. Conclusion: Workers in the clay brick industry showed evidence of liver disease that could be related to matrix remodeling. PMID:24999850

    Aerosols are indicators of air quality as they reduce visibility and adversely affect public health. Aerosol optical depth (AOD) is a measure of the radiation extinction due to interaction of radiation with aerosol particles in the atmosphere. Using this optical measure of atmospheric aerosols we explore the seasonal and annual patterns of aerosols from both anthropogenic and biogenic sources over Egypt. Here, we use an integrated environment-climate-aerosol model in conjunction with inversion technique to identify the aerosol particle size distribution over different locations in Egypt. The online-integrated Environment-Climate-Aerosol model (EnvClimA), which is based on the International Center for Theoretical Physics Regional Climate Model (ICTP-RegCM), is used to study the emission of different aerosols and their impact on climate parameters for a long-term base line simulation run over Egypt and North Africa. The global emission inventory is downscaled and remapping them over Egypt using local factors such as population, traffic and industrial activities to identify the sources of anthropogenic and biogenic emission from local emission over Egypt. The results indicated that the dominant natural aerosols over Egypt are dust emissions that frequently occur during the transitional seasons (Spring and Autumn). From the local observation we identify the number of dust and sand storm occurrences over Egypt. The Multiangle Imaging SpectroRadiometer (MISR) is used to identify the optical characterizations of different types of aerosols over Egypt. Modeled aerosol optical depth and MISR observed (at 555 nm) are compared from March 2000 through November 2013. The results identify that the MISR AOD captures the maximum peaks of AOD in March/April that coincide with the Khamasin dust storms. However, peaks in May are either due to photochemical reactions or anthropogenic activities. Note: This presentation is for a Partnerships for Enhanced Engagement in Research (PEER

    A two-dimensional groundwater flow model was constructed to investigate the long-term hydrologic impacts of Lake Nasser and the major land reclamation projects that use excess lake water in southwest Egypt. Egypt constructed (1964-1971) the Aswan High Dam, creating the Lake Nasser reservoir (length: 500 km; average width: 12 km) and is constructing the Tushka Canal to channel 5.0x10{sup 9} m{sup 3}/yr of Lake Nasser water to reclaim 0.5x10{sup 6} acres of desert lands. The model, constrained by regional-scale groundwater flow and near-lake head data, was successfully calibrated to temporal-observation heads from 1970 to 2000 that reflect variations in lake levels. Predictive analyses for the subsequent 50-yr period were conducted by employing the calibrated model. Simulations of long-term effects, beyond year 2000, of Lake Nasser on recharge and temporal groundwater head (base case scenario) show that recharge from the lake will continue at a much slower rate than during the 30-yr period of 1970-2000 (with approximately 86% reduction in 30-yr recharge). The modest projected pumping and injection activities in the study area are not expected to cause major deviation in the overall head distribution compared to the base case scenario. The investigation of effects of the new irrigation land development on the Nubian aquifer indicated that many of the proposed irrigation areas, especially those with small aquifer thickness, will become fully saturated with introduced water, resulting in potential flooding and salinization.

    This study was carried out to investigate the prevalence and monthly intensity of Rhinoestrus (R) spp. among donkeys slaughtered at Giza Zoo abattoir, Egypt. A total of 144 donkeys were examined at postmortem through two visits per month from January 2010 to December 2010. All donkeys were infested with one or more larval stages during all months of the examination period (100%). The 1st and 2nd stage larvae (L1 and L2) were mostly observed in the turbinate bones and seldom in the nasal passages, whereas the 3rd stage larvae (L3) were observed mostly in ethmoid and lamina cribrosa and rarely in nasal passages and pharynx. The highest monthly intensity of infestation with the total number of larval stages was recorded in January and August, while the lowest occurred in September. L1 was observed during all months with two peaks in January and June. L2 occurred from February to April, July, and August. L3 was present from March to May, August, and September. The ranked size of infestation with the total number of the 3 larval stages of Rhinoestrus spp. showed that a total of 107 donkeys had 1-10 larvae; 34 had 11-30 larvae; and 3 harbored 31-50 larvae. The morphology and molecular characterization of the third stage larvae of Rhinoestrus spp. were investigated. Morphologically, two morphotypes (1 and 2) of Rhinoestrus spp. (R. usbekistanicus like and the other R. purpureus like) were reported. Whereas molecular sequencing of mitochondrial cytochrome-oxidase subunit I showed 99% homology with those of R. usbekistanicus. In conclusion, Rhinoestrus spp. present in Egypt is mainly R. usbekistanicus, which includes two morphotypes, R. usbekistanicus like and R. purpureus like.

    method, 66 of the 118 isolates (55%) could be genotypically assigned to O-types. Conclusion: This study is considered to be a first report of the high prevalence of ESBL-producing E. coli in dairy farms in Egypt. ESBL-producing E. coli isolates with different underlying resistance mechanisms are common in investigated dairy cattle farms in Egypt. The global rise of ESBL- and carbapenemase-producing Gram-negative bacteria is a big concern, and demands intensified surveillance. PMID:27458435

  12. Important Results From Shallow Seismic Observations at the Ancient Hierakonpolis Temple-Town Site in Upper Egypt

    A number of shallow seismic profiles were run within the walled 200x300m perimeter of the ancient Hierakonpolis Temple-Town site in Upper Egypt as part of an interdisciplinary investigation of the progressive rise in the water table caused by nearby irrigation practices. Each of these lines provided a profile of water table depth that is accurate to within approximately 10-15 cm when compared to point measurements on a piezometer array. Water table depths currently range from approximately 0.6m to 1.5m mainly because of buried structures and there is a seasonal variation modulating a steady shallowing trend. Prominent continuous high-velocity, high-frequency (200-300Hz)signals from very shallow depths above the water table were observed along some of these profiles and additional crossing lines were run to map these anomalies; this high-velocity layer is imbedded in the upper layer of unconsolidated, air-filled sediments that have extremely low velocities and very low Q. Subsequent shallow excavations (2001, 2005-2010) at several locations on the site have revealed that the cause of this shallow high-velocity layer is the presence of a zone of closely spaced artifacts (dense in potsherds and stone fragments) above the water table that reveal new, previously-unknown evidence of occupation in the ancient town as early as Dynasty I, c. 3200 BCE. In the northwest excavation an 'in situ' deposit of special pottery lies next to a bench, a large block of dressed limestone. Further to the north, layered occupation suggests a secular context with pottery of Dynasty II, 2900 BCE and a new early date, terminus ante quem, for the accompanying figurines, thus far exclusive to two temple sites in southern Egypt. Of key significance is the discovery of the first reported ebony artifacts (leg of a statue and eyes) found in the region, and rare anywhere in Egypt. To date only a fraction of these anomalous areas have been excavated, so important additional new archaeological finds

    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.

    A number of recent studies have, by necessity, placed a great deal of emphasis on the dental evidence for Paleogene anthropoid interrelationships, but cladistic analyses of these data have led to the erection of phylogenetic hypotheses that appear to be at odds with biogeographic and stratigraphic considerations. Additional morphological data from the cranium and postcranium of certain poorly understood Paleogene primates are clearly needed to help test whether such hypotheses are tenable. Here we describe humeri attributable to Proteopithecus sylviae and Catopithecus browni, two anthropoids from late Eocene sediments of the Fayum Depression in Egypt. Qualitative and morphometric analyses of these elements indicate that humeri of the oligopithecine Catopithecus are more similar to early Oligocene propliopithecines than they are to any other Paleogene anthropoid taxon, and that Proteopithecus exhibits humeral similarities to parapithecids that may be symplesiomorphies of extant (or “crown”) Anthropoidea. The humeral morphology of Catopithecus is consistent with certain narrowly distributed dental apomorphies—such as the loss of the upper and lower second premolar and the development of a honing blade for the upper canine on the lower third premolar—which suggest that oligopithecines constitute the sister group of a clade containing propliopithecines and Miocene-Recent catarrhines and are not most closely related to Proteopithecus as has recently been proposed.

    The dynamics of ecosystem collapse are fundamental to determining how and why biological communities change through time, as well as the potential effects of extinctions on ecosystems. Here, we integrate depictions of mammals from Egyptian antiquity with direct lines of paleontological and archeological evidence to infer local extinctions and community dynamics over a 6,000-y span. The unprecedented temporal resolution of this dataset enables examination of how the tandem effects of human population growth and climate change can disrupt mammalian communities. We show that the extinctions of mammals in Egypt were nonrandom and that destabilizing changes in community composition coincided with abrupt aridification events and the attendant collapses of some complex societies. We also show that the roles of species in a community can change over time and that persistence is predicted by measures of species sensitivity, a function of local dynamic stability. To our knowledge, our study is the first high-resolution analysis of the ecological impacts of environmental change on predator–prey networks over millennial timescales and sheds light on the historical events that have shaped modern animal communities.

    In the Nile Valley and Delta the protection of groundwater resources is high priority environmental concern. Many groundwater quality problems are already dispersed and may be widespread and frequent in occurrence. Examples include problems associated with the extensive application of chemical fertilizers in agricultural specially in the new reclaimed areas, leaks in sewers, septic tanks, the aggregate effects of many different points source pollution in urban areas and natural, geologically related water quality problems. A national groundwater quality monitoring has been designed and implemented based on the stepwise procedure. The national groundwater quality monitoring network is used to quantify the quality changes in long run, either caused by pollution activities or by salt water intrusion and to describe the overall current groundwater quality status on a national scale of the main aquifers. The monitoring tools and methodologies developed in this research can be used to assure protection of public health and determine the sustainability of groundwater in various purposes. This national monitoring network plays important roles for decision makers in developing the groundwater resources management plans in different aquifers systems in Egypt.

    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.

    Depressions of the Western Desert of Egypt (specifically, Kharga, Farafra, and Kurkur regions) are mainly occupied by shales that are impermeable, but easily erodible by rainfall and runoff, whereas the surrounding plateaus are composed of limestones that are permeable and more resistant to fluvial erosion under semiarid to arid conditions. A computer simulation model was developed to quantify the ground-water sapping processes, using a cellular automata algorithm with coupled surface runoff and ground-water flow for a permeable, resistant layer over an impermeable, friable unit. Erosion, deposition, slumping, and generation of spring-derived tufas were parametrically modeled. Simulations using geologically reasonable parameters demonstrate that relatively rapid erosion of the shales by surface runoff, ground-water sapping, and slumping of the limestones, and detailed control by hydraulic conductivity inhomogeneities associated with structures explain the depressions, escarpments, and associated landforms and deposits. Using episodic wet pulses, keyed by {delta}{sup 18}O deep-sea core record, the model produced tufa ages that are statistically consistent with the observed U/Th tufa ages. This result supports the hypothesis that northeastern African wet periods occurred during interglacial maxima. This {delta}{sup 18}O-forced model also replicates the decrease in fluvial and sapping activity over the past million years. 65 refs., 21 figs., 2 tabs.

    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.

    The present tectonic features of the northeast African shelf margin between the Nile delta and the Gulf of Sirte are products of (1) precursory late Paleozoic basement arches, (2) early Mesozoic rifting and plate separation, and (3) Late Cretaceous structural inversion. The 250 km-wide and highly differentiated Mesozoic passive margin in the Western Desert region of Egypt is developed above a broad northwest-trending Late Carboniferous basement arch. In northeastern Libya, in contrast, the passive margin is restricted to just the northernmost Cyrenaica platform, where subsidence was extremely rapid in the Jurassic and Early Cretaceous. The boundary between the Western Desert basin and the Cyrenaica platform is controlled by the western flank of the basement arch. In the middle Cretaceous (100-90 Ma), subsidence accelerated over large areas of the Western desert, further enhancing a pattern of east-west-trending subbasins. This phase of rapid subsidence was abruptly ended about 80 Ma by the onset of structural inversion that uplifted the northern Cyrenaica shelf margin and further differentiated the Western Desert subbasin along a northeasterly trend.

    Parental expectations about the companionship and assistance they will receive in later life from their children are key considerations in family formation decisions. We explore patterns of parents' investment and the support and contact they receive from adult children in Egypt, where fertility is falling and sources of support at all life stages are in flux. Using data from a survey of older adults in Ismailia governorate, we consider parents' past investments in childbearing, child survival, and children's education and marriage, as well as recent assistance to adult children via housing, care for grandchildren, gifts, and money. The returns from children considered include economic assistance, instrumental support, and visits. Most parental investments are associated with frequent visits from children. The assistance children provide to parents is gendered: sons tend to provide economic transfers, whereas daughters tend to provide instrumental help. A greater number of surviving children is most strongly associated with parents' receipt of multiple types of later-life returns. Investments in children's education and marriage are not associated with assistance, but recent assistance to children-especially economic transfers and provision of housing-is associated with receiving instrumental assistance from adult children.

    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. PMID:24327928

    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.

    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

    The contents of natural radionuclides ((226)Ra, (232)Th and (40)K) were measured in sedimentary phosphate rock samples (Abu-Tartur phosphate, Western Desert Egypt) by using gamma spectrometry (NaI (Tl) 3"x 3"). Phosphate and environmental samples were collected from Abu-Tartur phosphate mine and the surrounding region. The results are discussed and compared with the levels in phosphate rocks from different countries. The activities of (226)Ra, (232)Th series and (40)K are between (14.9 +/- 0.8 and 302.4 +/- 15.2), (2.6 +/- 1.0 and 154.9 +/- 7.8) and (10.0 +/- 0.5 and 368.4 +/- 18.4) Bq kg(-1), respectively. The Abu-Tartur phosphate deposit was found to have lower activity than many others exploited phosphate sedimentary deposits, with its average total annual dose being only 114.6 microSv y(-1). This value is about 11.46% of the 1.0 mSv y(-1) recommended by the International Commission on Radiological Protection (ICRP-60, 1990) as the maximum annual dose to members of the public.

    Tsunami deposits and dragged large boulders are investigated along the Mediterranean coast of Egypt in the framework of the EC-Funded ASTARTE project (Assessment, Strategy And Risk Reduction for Tsunamis in Europe - FP7-ENV2013 6.4-3, Grant 603839) and the French-Egyptian IMHOTEP project. The targeted zones located west of Alexandria are selected according to historical earthquakes and related inundation events as recorded in archives. Field investigations include: 1) Coastal geomorphology along estuaries, wedge-protected and dune-protected lagunas, and terrace-platforms as potential sites for paleotsunami and boulder records and 2) Investigations of paleotsunamis deposits and their spatial distribution using trenching and coring. The two selected sites at Kefret Saber (immediately west of Marsah Matrouh town) and near El Alamein village are inner lagunas protected by 2 to 40-m-high dunes parallel to the shoreline. Five trenches and six cores dug in Kefret Saber and 1 trench in Alamein revealed an almost identical 5 to 10-cm-thick white sand unit with highly reworked fossil-rich and shells at about 20 to 40-cm-depth, intercalated in light brown laminated sandy and sandy-clay deposits. A total of 50 samples of organic deposits and charcoal fragments were collected from both sites, among which 20 samples have been dated. Dated charcoal in deposits above and below the white sand unit lead us to correlate with the 24 June 1870 major earthquake (M 7.5 - 8.0?) that generated a tsunami with the inundation of Alexandria harbor. Major seismic sources being along the Hellenic subduction zone and Cyprus arc, our progress study of paleotsunami deposits and their distribution along the Egyptian coast will help in a better constraint of the size and recurrence of tsunamis, and their propagation over the east Mediterranean regions.

    A dairy farm keeping Holstein cattle and buffaloes in the Menoufia Governorate was investigated during and after the last Foot and Mouth Disease (FMD) outbreak in Egypt (starting February 2012) to determine the impact of the outbreak on animals as well as to assess some factors that might have helped to spread the disease in the investigated farm. All animals were vaccinated against FMD with the locally produced bivalent vaccine containing O1 and A/Egy/2006 strains two months before the onset of the outbreak. Laboratory examination of the samples collected from diseased and dead animals' revealed detection of a newly emerged serotype of FMD (SAT2). Although, all buffaloes (8/8) in the herd were infected (100%), none of them died, while lactating Holstein cattle showed varying morbidity rates along the period of the outbreak with peak rates in March followed by April, May and June. Crud mortality and case fatality rates among cattle peaked during April 2012 to reach 9.3 and 21.7%, respectively. Calves were the most affected animals with the highest morbidities and mortalities. The high prevalence of the disease among all animal categories in the investigated farm is attributed to the lack of previous immunity through vaccination against the new serotype of the virus. In addition, the hygienic and biosecurity measures in the farm were unsatisfactory with respect to prevention of introduction and spread of the disease between the farm units. The prevalent weather conditions during the outbreak might have played a role in spread of the FMDv, especially ambient temperature, humidity and wind movement.

    This study is concerned with the efficiency of World Bank projects in Egypt. The study seeks improvements in the methods of evaluating public sector projects in Egypt. To approaches are employed: (1) project identification to optimally allocate Egypt's and World Bank's resources; (2) project appraisal to assess the economic viability and efficiency of investments. The electricity sector is compared with the agriculture sector as a means of employing project identification for priority ordering of investment for development in Egypt. The key criteria for evaluation are the impacts of developments of each sector upon Egypt's national objectives and needs. These include employment opportunities, growth, alleviation of poverty, cross comparison of per capita consumption in each sector, economic rate of return, national security, balance of payments and foreign debt. The allocation of scarce investments would have been more efficient in agriculture than in electricity in meeting Egypt's national objectives and needs. World Bank lending programs in Egypt reveal a priority ordering of electricity over agriculture and rural development. World Bank development projects in Egypt have not been optimally identified, and its programs have not followed an efficient allocation of World Bank's and Egypt's resources. The key parameters in evaluating economic viability and efficiency of development projects are: (1) the discount rate (the opportunity cost of public funds); (2) the exchange rate; and (3) the cost of major inputs, as approximated by shadow prices of labor, water, electricity, and transportation for development projects. Alternative approaches to estimating the opportunity cost of public funds are made. The parameters in evaluating the efficiency of projects have not been accurately estimated in the appraisal stage of the World Bank projects in Egypt, resulting in false or misleading information concerning the economic viability and efficiency of the projects.

    In order to understand better the polygenetic evolution of landforms on the martian surface, field studies were conducted in and around the Kharga Depression, Egypt. The Kharga region, on the eastern edge of Egypt's Western Desert, was subject to erosion under mostly hyperarid climatic conditions, punctuated by brief pluvial episodes of lesser aridity, since early Pleistocene time. The region contains numerous landforms analogous to features on the martian surface: yardangs carved in layered surficial deposits and in bedrock, invasive dune trains, wind-modified channels and interfluves, and depressions bounded by steep scarps. Like many of the topographic depresions on Mars, the Kharga Depression was invaded by crescentic dunes. In Egypt, stratigraphic relations between dunes, yardangs, mass-wasting debris, and wind-eroded flash-flood deposits record shifts in the relative effectiveness of wind, water, and mass-wasting processes as a function of climate change.

    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.

    Little is known about the genetic diversity of Sarcoptes scabiei mites in farm animals in Egypt. In this study, we characterized S. scabiei in 25 skin scrapes from water buffalo, cattle, sheep, and rabbits at the nuclear marker ITS2 and mitochondrial markers COX1 and 16S rRNA. Sequences of the ITS2 showed no host segregation or geographical isolation, whereas those of the mitochondrial COX1 and 16S rRNA genes indicated the presence of both host-adapted and geographically segregated populations of S. scabiei. Host adaptation may limit inter-species transmission of. S. scabiei, thus restrict gene flow among S. scabiei from different hosts. This is the first report on the molecular characterization of sarcoptic mites in Egypt. Further genetic studies involving larger numbers of specimens, especially those from humans and companion animals, are needed to understand the molecular epidemiology of sarcoptic mange in Egypt.

    The Egyptian state was formed prior to the existence of verifiable historical records. Conventional dates for its formation are based on the relative ordering of artefacts. This approach is no longer considered sufficient for cogent historical analysis. Here, we produce an absolute chronology for Early Egypt by combining radiocarbon and archaeological evidence within a Bayesian paradigm. Our data cover the full trajectory of Egyptian state formation and indicate that the process occurred more rapidly than previously thought. We provide a timeline for the First Dynasty of Egypt of generational-scale resolution that concurs with prevailing archaeological analysis and produce a chronometric date for the foundation of Egypt that distinguishes between historical estimates.

    This commentary describes a visit to the Female Genital Mutilation/Cutting project in Cairo. FGM/C is a very serious problem in Egypt and other countries in the North of Africa. Among girls between the age of 15-17, 77% have been cut, with very serious health consequences. In Egypt, there is a comprehensive strategy led by very enthusiastic employees of the National Council for Childhood and Motherhood with support of UNICEF. At a national level a broad coalition is being built that tries to mobilise the legal, medical and media communities to overcome the practice of FGM/C and realising adequate laws that criminalise FGM/C.At a local level two community projects were started in 160 villages in Upper and Lower Egypt for raising community awareness and dialogue on FGM/C. That is the only way to create a growing social movement that can collectively abandon the practice of FGM/C.

    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.

    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.

Five different louse-borne bacterial agents were detected in lice from rodents or cattle, including "Bartonella rattimassiliensis", "B. phoceensis", and Bartonella sp. near Bartonella tribocorum, Coxiella burnetii, and Rickettsia typhi. More lice from governorates bordering the Mediterranean and Red Seas contained pathogens. Our data indicate that lice of urban and domestic animals harbor pathogenic or potentially pathogenic bacterial agents throughout Egypt.

    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.

She and her co-authors state that those 5 phases include a prior training and demonstration phase that was completed in the Imaging Unit of Kasr El Aini Hospital in Cairo, as well as a one-year pilot phase completed between October 2007 and October 2008. Authors present us with results of screening of 20.098 women over the age of 45 years, between October 30, 2007 and February 9, 2009 in Cairo, Alexandria and Suez Governorates in Egypt. In addition to breast cancer, WHOP included screening for diabetes, hypertension and obesity. WHOP investigators are to be congratulated for this extraordinary ambitious project and all the efforts put into it. They were well prepared in regards to having a multi-disciplinary working team and they included in their project programs for training of clerks, data managers, radiographers, nurses, radiologists and other physicians who deal with diagnosis and management of breast cancer. They also included engineers and arranged for mobile units to reach women who could not otherwise reach them. WHOP investigators are to be commended also for performing a field plan demonstration project and testing it and for measuring citizens' response before finalizing their plans and starting the project1.

    Chlorine has been utilized in the early stages of water treatment processes as disinfectant. Disinfection for drinking water reduces the risk of pathogenic infection but may pose a chemical threat to human health due to disinfection residues and their by-products (DBP) when the organic and inorganic precursors are present in water. In the last two decades, many modeling attempts have been made to predict the occurrence of DBP in drinking water. Models have been developed based on data generated in laboratory-scale and field-scale investigations. The objective of this paper is to develop a predictive model for DBP formation in the Alexandria governorate located at the northern west of Egypt based on field-scale investigations as well as laboratory-controlled experimentations. The present study showed that the correlation coefficient between trihalomethanes (THM) predicted and THM measured was R (2)=0.88 and the minimum deviation percentage between THM predicted and THM measured was 0.8 %, the maximum deviation percentage was 89.3 %, and the average deviation was 17.8 %, while the correlation coefficient between dichloroacetic acid (DCAA) predicted and DCAA measured was R (2)=0.98 and the minimum deviation percentage between DCAA predicted and DCAA measured was 1.3 %, the maximum deviation percentage was 47.2 %, and the average deviation was 16.6 %. In addition, the correlation coefficient between trichloroacetic acid (TCAA) predicted and TCAA measured was R (2)=0.98 and the minimum deviation percentage between TCAA predicted and TCAA measured was 4.9 %, the maximum deviation percentage was 43.0 %, and the average deviation was 16.0 %.

    An analysis is presented of the discovered crude oil resources, reserves, and estimated annual production from known fields of the Republics of Libya, Algeria, and Egypt. Proved reserves are defined as the remaining producible oil as of a specified date under operating practice in effect at that time and include estimated recoverable oil in undrilled portions of a given structure or structures. Also included in the proved reserve category are the estimated indicated additional volumes of recoverable oil from the entire oil reservoir where fluid injection programs have been started in a portion, or portions, of the reservoir. The indicated additional reserves (probable reserves) reported herein are the volumes of crude oil that might be obtained with the installation of secondary recovery or pressure maintenance operations in reservoirs where none have been previously installed. The sum of cumulative production, proved reserves, and probable reserves is defined as the ultimate oil recovery from known deposits; and resources are defined as the original oil in place (OOIP). An assessment was made of the availability of crude oil under three assumed sustained production rates for each country; an assessment was also made of each country's capability of sustaining production at, or near, the 1980 rates assuming different limiting reserve to production ratios. Also included is an estimate of the potential maximum producing capability from known deposits that might be obtained from known accumulations under certain assumptions, using a simple time series approach. The theoretical maximum oil production capability from known fields at any time is the maximum deliverability rate assuming there are no equipment, investment, market, or political constraints.

    Population growth is an issue that policy makers have not been able to integrate into their policy planning even though it is often a primary force. National security is often planned without any consideration of population growth, immigration policy, food balance, environmental and resource issues, social issues, and foreign policy issues. The author constructs a scenario in which Suddam Hussein has been eliminated, but little progress has been made on the Israel-Palestine issue. The time is February 1995; Egypt's population has grown from 37 million to 63 million in only 20 years. Because of declining oil production and steady US foreign aid, it is unable to feed its people. There are food riots, the government is overthrown, and a Islamic fundamentalist leader comes to power who declares a holy war on Israel. Worldwide grain stocks continue their period of stagnation in growth while worldwide consumptions grows. The US grain stocks fall to record lows because of stagnant increases in crop yields, but a growing population from slightly higher fertility and increased immigration continues with a high level of consumption. Oil imports reached 50% of consumption in 1991 and this situation worsens the balance of trade, foreign capital begins to leave the US. While the scenario is unlikely to happen just this way, the facts as of 1990 are clear that many different trends are presently taking the US into danger. The short sighted policy decision of the Reagan/Bush administrations have attempted to maintain business as usual. An area in which they changed was their drastic cutting of funding for family planning. Population size is the single largest factor affection oil consumption, food consumption and environmental quality. Yet the policy makers are not making policies that take these issues into account.

    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.

    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.

Data on sociodemographic and environmental characteristics of the family, morbidity profiles, and breast-feeding patterns were collected from mothers of the children. Anthropometric measurements were performed, and the prevalence of malnutrition was assessed using three indicators, such as stunting, under-weight, and wasting, following the WHO guidelines and cut-off points. Simple and multiple regression analyses were done for examining the factors associated with the occurrence of malnutrition using principal component factor analysis with varimax rotation. Stunting, under-weight, and wasting were observed in 15%, 7.3%, and 3.6% of the children respectively. High-socioeconomic condition was associated with low prevalence of stunting and underweight (OR = 0.67, confidence interval (CI) = 0.55-0.8 and OR = 0.75, CI = 0.58-0.96 respectively). Good environmental condition was associated with a lower stunting rate (OR = 0.83, CI = 0.72-0.96). Increased age of child and living in a non-squatter area were associated with wasting (OR = 1.02, CI = 1.001-1.03 and OR = 0.38, CI = 0.15-0.97 respectively). Interventions to improve socioeconomic and environmental situations are recommended to reduce the already low level of protein-energy malnutrition further.

    Introduction As one of the leading causes of death and disability in the world, human trauma and injury disproportionately affects individuals in developing countries. To meet the need for improved trauma care in Egypt, the Sequential Trauma Emergency/Education ProgramS (STEPS) course was created through the collaborative effort of U.S. and Egyptian physicians. The objective of course development was to create a high quality, modular, adaptable and sustainable trauma care course that could be readily adopted by a lower- or middle- income country. Methods We describe the development, transition and host-nation sustainability of a trauma care training course between a high income Western nation and a lower-middle income Middle Eastern/Northern African country, including number of physicians trained and challenges to program development and sustainability. Results STEPS was developed at the University of Maryland, based in part on World Health Organization’s Emergency and Trauma Care materials, and introduced to the Egyptian Ministry of Health and Population (MOHP) and Ain Shams University in May 2006. To date, 639 physicians from multiple specialties have taken the 4-day course through the MOHP or public/governmental universities. In 2008, the course transitioned completely to the leadership of Egyptian academic physicians. Multiple Egyptian medical schools and the Egyptian Emergency Medicine Board now require STEPS or its equivalent for physicians in training. Conclusions Success of this collaborative educational program is demonstrated by the numbers of physicians trained, the adoption of STEPS by the Egyptian Emergency Medicine Board, and program continuance after transitioning to in-country leadership and trainers.

    Background: Solid waste management has emerged as an important human and environmental health issue. Municipal solid waste workers (MSWWs) are potentially exposed to a variety of occupational biohazards and safety risks. The aim of this study was to describe health practices and safety measures adopted by workers in the main municipal company in Alexandria (Egypt) as well as the pattern of the encountered work related ill health. Methods: A cross-sectional study was conducted between January and April 2013. We interviewed and evaluated 346 workers serving in about 15 different solid waste management activities regarding personal hygiene, the practice of security and health care measures and the impact of solid waste management. Results: Poor personal hygiene and self-care, inadequate protective and safety measures for potentially hazardous exposure were described. Impact of solid waste management on health of MSWWs entailed high prevalence of gastrointestinal, respiratory, skin and musculoskeletal morbidities. Occurrence of accidents and needle stick injuries amounted to 46.5% and 32.7% respectively. The risk of work related health disorders was notably higher among workers directly exposed to solid waste when compared by a group of low exposure potential particularly for diarrhea (odds ratio [OR] = 2.2, 95% confidence interval [CI] = 1.2-3.8), vomiting (OR = 2.7, 95% CI = 1.1-6.6), abdominal colic (OR = 1.9, 95% CI = 1.1-3.2), dysentery (OR = 3.6, 95% CI = 1.3-10), dyspepsia (OR = 1.8, 95% CI = 1.1-3), low back/sciatic pain (OR = 3.5, 95% CI = 1.8-7), tinnitus (OR = 6.2, 95% CI = 0.3-122) and needle stick injury (OR = 3.4, 95% CI = 2.1-5.5). Conclusions: Workers exposed to solid waste exhibit significant increase in risk of ill health. Physician role and health education could be the key to assure the MSWWs health safety. PMID:24932385

  5. Update of fasciolosis-transmitting snails in Egypt (review and comment).

    PubMed

    Dar, Y D; Rondelaud, D; Dreyfuss, G

    2005-08-01

    Several snail species may contribute in transmission of fasciolosis in Egypt. These molluscs show a variable sensibility to natural infections with Fasciola species. Radix natalensis is considered to be the essential intermediate host for F. gigantica based on field and experimental studies. Cercarial production from R. natalensis experimentally infected with F. gigantica is affected by the species of definitive host from which the eggs are obtained, as well as the different laboratory conditions. Another lymnaeid, Galba truncatula, may play a role in transmitting this parasite in Egypt, as it was found naturally infected with F. gigantica. Latter snail species, originated from France, was susceptible to experimental infections with Egyptian miracidia of F. gigantica and it had a cercarial production close to that of local R. natalensis. Two other snails, Pseudosuccinea columella and Biomphalaria alexandrina, were naturally found harboring larvae of Fasciola sp. At the level of intermediate hosts of F. gigantica, the conditions are thus favorable in Egypt to transmit fasciolosis which could also be caused by another fasciolid, F. hepatica, as the existance of this fluke was confirmed in Egypt.

    Background Influenza typically comprises a substantial portion of acute respiratory infections, a leading cause of mortality worldwide. However, influenza epidemiology data are lacking in Egypt. We describe seven years of Egypt’s influenza hospitalizations from a multi-site influenza surveillance system. Methods Syndromic case definitions identified individuals with severe acute respiratory infection (SARI) admitted to eight hospitals in Egypt. Standardized demographic and clinical data were collected. Nasopharyngeal and oropharyngeal swabs were tested for influenza using real-time reverse transcription polymerase chain reaction and typed as influenza A or B, and influenza A specimens subtyped. Results From November 2007–November 2014, 2,936/17,441 (17%) SARI cases were influenza-positive. Influenza-positive patients were more likely to be older, female, pregnant, and have chronic condition(s) (all p<0.05). Among them, 53 (2%) died, and death was associated with older age, five or more days from symptom onset to hospitalization, chronic condition(s), and influenza A (all p<0.05). An annual seasonal influenza pattern occurred from July–June. Each season, the proportion of the season’s influenza-positive cases peaked during November–May (19–41%). Conclusions In Egypt, influenza causes considerable morbidity and mortality and influenza SARI hospitalization patterns mirror those of the Northern Hemisphere. Additional assessment of influenza epidemiology in Egypt may better guide disease control activities and vaccine policy. PMID:27607330

    Mycobacterium avium subspecies paratuberculosis (M. paratuberculosis) is the causative agent of paratuberculosis, or Johne's disease, in cattle, with potential involvement in cases of Crohn's disease in humans. Johne's disease is found worldwide and is economically important for both beef and dairy industries. In an effort to characterize this important infection in Egypt, we analysed the ecological and genomic features of recent isolates of M. paratuberculosis. In this report, we examined 26 Holstein dairy herds distributed throughout Egypt, from 2010 to 2013. Using PCR analysis of faecal samples, we estimated a mean herd-level prevalence of 65.4 %, with animal-level infection that reached a mean of 13.6 % among animals suffering from diarrhoea. Whole genome sequencing of field isolates identified numerous single nucleotide polymorphisms among field isolates relative to the standard M. paratuberculosis K10 genome. Interestingly, the virulence of M. paratuberculosis isolates from Egypt revealed diverse virulence phenotypes in the murine model of paratuberculosis, with significant differences in tissue colonization, particularly during the chronic stage of infection. Overall, our analysis confirmed that Johne's disease is a newly identified problem in Egypt and indicated that M. paratuberculosis has potentially diverse genotypes that impact its virulence. Further ecological mapping and genomic analysis of M. paratuberculosis will enhance our understanding of the transmission and evolutionary dynamics of this pathogen under natural field conditions.

    2010-12-01

    Records of Egyptian fungi, including lichenized fungi, are scattered through a wide array of journals, books, and dissertations, but preliminary annotated checklists and compilations are not all readily available. This review documents the known available sources and compiles data for more than 197 years of Egyptian mycology. Species richness is analysed numerically with respect to the systematic position and ecology. Values of relative species richness of different systematic and ecological groups in Egypt compared to values of the same groups worldwide, show that our knowledge of Egyptian fungi is fragmentary, especially for certain systematic and ecological groups such as Agaricales, Glomeromycota, and lichenized, nematode-trapping, entomopathogenic, marine, aquatic and coprophilous fungi, and also yeasts. Certain groups have never been studied in Egypt, such as Trichomycetes and black yeasts. By screening available sources of information, it was possible to delineate 2281 taxa belonging to 755 genera of fungi, including 57 myxomycete species as known from Egypt. Only 105 taxa new to science have been described from Egypt, one belonging to Chytridiomycota, 47 to Ascomycota, 55 to anamorphic fungi and one to Basidiomycota.

    Gomaa, Nasr H.

    2012-01-01

    The floristic composition and species diversity of the germinable soil seed bank were studied in three different habitats (desert salinized land, desert wadi, and reclaimed land) in the Eastern Desert of Egypt. Moreover, the degree of similarity between the seed bank and the above-ground vegetation was determined. The seed bank was studied in 40 stands representing the three habitats. Ten soil samples (each 25 × 20 cm and 5 cm depth) were randomly taken per stand. The seed bank was investigated by the seedling emergence method. Some 61 species belonging to 21 families and 54 genera were identified in the germinable seed bank. The recorded species include 43 annuals and 18 perennials. Ordination of stands by Detrended Correspondence Analysis (DCA) indicates that the stands of the three habitats are markedly distinguishable and show a clear pattern of segregation on the ordination planes. This indicates variations in the species composition among habitats. The results also demonstrate significant associations between the floristic composition of the seed bank and edaphic factors such as CaCO3, electrical conductivity, organic carbon and soil texture. The reclaimed land has the highest values of species richness, Shannon-index of diversity and the density of the germinable seed bank followed by the habitats of desert wadi and desert salinized land. Motyka’s similarity index between the seed bank and the above-ground vegetation is significantly higher in reclaimed land (75.1%) compared to desert wadi (38.4%) and desert salinized land (36.5%).

    Integrons are genetic units characterized by the ability to capture and incorporate gene cassettes, thus can contribute to the emergence and transfer of antibiotic resistance. The objectives of this study were: (1) to investigate the presence and distribution of class I and class II integrons and the characteristics of the gene cassettes they carry in Enterobacteriaceae isolated from nosocomial infections at Zagzig University Hospital in Egypt, (2) to determine their impact on resistance, and (3) to identify risk factors for the existence of integrons. Relevant samples and full clinical history were collected from 118 inpatients. Samples were processed; isolated microbes were identified and tested for antibiotic susceptibilities. Integrons were detected by polymerase chain reaction (PCR) and were characterized into class I or II by restriction fragment length polymorphism (RFLP). Integron-positive isolates were subjected to another PCR to detect gene cassette, followed by gene cassette sequencing. Risk factors were analyzed by logistic regression analysis. Seventy-six Enterobacteriaceae isolates were recognized, 41 of them (53.9%) were integron-positive; 39 strains carried class I and 2 strains carried class II integrons. Integrons had gene cassettes encoding different combinations and types of resistance determinants. Interestingly, blaOXA129 gene was found and ereA gene was carried on class I integrons. The same determinants were carried within isolates of the same species as well as isolates of different species. The presence of integrons was significantly associated with multidrug resistance (MDR). No risk factors were associated for integron carriage. We conclude that integrons carrying gene cassettes encoding antibiotic resistance are significantly present among Enterobacteriaceae causing nosocomial infection in our hospital. Risk factors for acquisition remain to be identified. PMID:26157425

    The epidemiology and public health significance of Cryptosporidium species and genotypes were investigated in Beni-Suef Governorate, Egypt. A total of 610 animal fecal samples (480 from cattle and 130 from buffaloes) beside 290 stool samples from humans were collected in the period between January and December 2014. Based on the microscopic examination, the overall estimated prevalence of Cryptosporidium spp. in cattle, buffaloes, and humans was 10.2, 12.3, and 19 %, respectively. The highest detection rates were in calves less than 2 months of age (17.1 %) and diarrheic animals (13.0 %). Likewise in humans, the highest prevalence of Cryptosporidium was in infants (31.3 %) and diarrheic individuals (21.1 %). The gender distribution in humans denoted that Cryptosporidium was reported more frequently in males (21.7 %) than females (14.5 %). Based on the molecular characterization of Cryptosporidium, Cryptosporidium oocyst wall protein (COWP) and gp60 genes were successfully amplified in 36 out of 50 samples subjected to genotyping. Restriction fragment length polymorphism (RFLP) analysis of the COWP fragments revealed that Cryptosporidium parvum was the only species detected in cattle (12 isolates) and buffaloes (4 isolates), while in humans, the detected species were Cryptosporidium hominis (15 isolates) and C. parvum (5 isolates). Sequence analysis of the gp60 gene identified the subtype IIdA20G1 within C. parvum isolated from both animals and humans. The common occurrence of zoonotic subtypes of C. parvum in cattle and buffaloes highlights the potential role of these animals as significant reservoirs of infection to humans. Also, the presence of C. hominis and C. parvum in humans indicates that both anthroponotic and zoonotic pathways are expected.

    This study was performed for the purpose of investigating the prevalence of Sarcocystis spp. in buffaloes in Beni-Suef Governorate, Egypt. Both macroscopic (Sarcocystis fusiformis) and microscopic (Sarcocystis levinei) cysts were recognized, and were differentiated by their morphological features and location in the tissues. Of 379 buffaloes examined in abattoirs in Beni-Suef, 299 were found to be infected, with an overall prevalence of 78.9%. Depending on age, three categorized groups of naturally infected buffaloes were examined: male buffalo calves aged 1.5-2 years, adult females aged 2-5 years, and females older than 5 years. Among these groups, infection rates were 74.5%, 82.3%, and 81.2%, respectively. Organs examined included esophagus, tongue, and heart. Macroscopic cysts were examined by the naked eye through meat inspection in abattoirs, while the pepsin-digestion method and the histological technique were applied to detect microscopic cysts. It has been found that esophagus showed the highest rate of infection among the infected organs, with both macroscopic and microscopic cysts seen in the infected buffaloes. Moreover, results of the pepsin-digestion method proved more accurate than those produced by the histological technique in terms of infection rates for the microscopic cysts. Our findings indicated that infected buffaloes aged 2-5 years showed the highest mixed infection rate (82.3%) for both types of cysts. The high prevalence of microscopic Sarcocystis spp. in Beni-Suef Governorate reflects a significant role played by stray dogs, rather than cats, in the transmission of these parasites.

    This study investigated heavy metal pollution in sediments of the Rosetta branch of the River Nile of Egypt to quantify the toxic distribution potential of metals into the surrounding environment. Sediment samples were collected at 9 sites during in four seasons. Organic matter and total metal concentrations were determined using loss on ignition and inductively coupled plasma spectrometry, respectively. Principal component analysis has been applied to evaluate the metal sources and the relationships between metals in sediments. Metal concentrations showed the following order: winter > autumn > spring > summer. Mean concentrations of Cu, Zn, Cd, and Pb in sediments were above the average background value of metals in shale. Pb and Cd showed higher enrichment during all seasons at stations N3/N4, Zn at stations N1 to N4, and Cu at stations N6/N8. The variations in heavy metal total concentration and organic matter are due to different input sources, physico-chemical conditions, and adsorption/precipitation/redox conditions in sediments. Mean values of Geo-accumulation index (Igeo) for Fe, Mn, and Cu were below 0 which were classified as unpolluted during spring, summer, and autumn, except Cu increased from unpolluted to moderately polluted during winter. Igeo values for Cd, Pb, and Zn increased from unpolluted-moderately polluted to highly-very highly polluted during autumn and winter. Pollution Load Index was recorded in highest values during winter, especially at Fuwwah/Basioun and in lowest values during summer at after the Edfina Barrage/before Kafer El-Zayat due to industrial/human activities. Both natural and anthropogenic sources contributed to the metal accumulations in sediments, and industrial, agricultural, and municipal sewage effluents discharged from non-point sources may be the main anthropogenic sources for metals in the Rosetta branch.

    Agricultural reclamation activities during the last few decades in the Western Nile Delta have led to great changes in the groundwater levels and quality. In Egypt, changing the desert land into agricultural land has been done using transferred Nile water (through irrigation canal systems) or/and groundwater. This research investigates the hydrogeochemical changes accompanying the reclamation processes in the small basin of Abu Mina, which is part of the Western Nile Delta region. In summer 2008, 23 groundwater samples were collected and groundwater levels were measured in 40 observation wells. Comparing the groundwater data of the pre-reclamation (1974) and the post-reclamation (2008) periods, groundwater seems to have been subjected to many changes: rise in water level, modification of the flow system, improvement of water quality, and addition of new salts through dissolution processes. Generally, Abu Mina basin is subdivided into two areas, recharge and discharge. The dissolution and mixing were recognized in the recharge areas, while the groundwater of the discharge region carries the signature of the diluted pre-reclamation groundwater. The salts of soil and aquifer deposits play an important role in the salt content of the post and pre-reclamation groundwater. NaCl was the predominant water type in the pre-reclamation groundwater, while CaSO4, NaCl and MgSO4 are the common chemical facies in the post-reclamation groundwater. The post-reclamation groundwater mostly indicates mixing between the pre-reclamation groundwater and the infiltrated freshwater with addition of some ions due to interaction with soil and sediments.

    Backgrounds With 10% of the general population aged 15–59 years chronically infected with hepatitis C virus (HCV), Egypt is the country with the highest HCV prevalence worldwide. Healthcare workers (HCWs) are therefore at particularly high risk of HCV infection. Our aim was to study HCV infection risk after occupational blood exposure among HCWs in Cairo. Methodology/Principal Findings The study was conducted in 2008–2010 at Ain Shams University Hospital, Cairo. HCWs reporting an occupational blood exposure at screening, having neither anti-HCV antibodies (anti-HCV) nor HCV RNA, and exposed to a HCV RNA positive patient, were enrolled in a 6-month prospective cohort with follow-up visits at weeks 2, 4, 8, 12 and 24. During follow-up, anti-HCV, HCV RNA and ALT were tested. Among 597 HCWs who reported a blood exposure, anti-HCV prevalence at screening was 7.2%, not different from that of the general population of Cairo after age-standardization (11.6% and 10.4% respectively, p = 0.62). The proportion of HCV viremia among index patients was 37%. Of 73 HCWs exposed to HCV RNA from index patients, nine (12.3%; 95%CI, 5.8–22.1%) presented transient viremia, the majority of which occurred within the first two weeks after exposure. None of the workers presented seroconversion or elevation of ALT. Conclusions/Significance HCWs of a general University hospital in Cairo were exposed to a highly viremic patient population. They experienced frequent occupational blood exposures, particularly in early stages of training. These exposures resulted in transient viremic episodes without established infection. These findings call for further investigation of potential immune protection against HCV persistence in this high risk group. PMID:23469082

    Recent multidisciplinary investigations of sediment cores from the ancient marine bay of Alexandria (Egypt) have documented local human activities during the Iron Age (circa 900-1000 B.C.) prior to Alexander the Great's arrival in 331 B.C. (Goiran, 2001; Véron et al., 2006; Stanley et al., 2007, 2010), corroborating the existence of the so-called "Rakhotis" as evoked in previous archaeological literature (Jondet, 1916; Weill, 1919; Chauveau, 1999; Baines, 2003). Lead (Pb) Isotopic Analyses (LIA) from Alexandria Bay indicate a possible anthropogenic imprint as early as circa 2300-2650 (±200) B.C. and, to a lesser extent, 3500-3800 (±170) B.C. (Véron et al., 2006). Here we demonstrate that LIA in sediments from the nearby Maryut Lagoon display isotopic anomalies resulting from the release of contaminant Pb into the Lagoon during the Egyptian Early dynastic (at 2897 ± 187 B.C) and Predynastic (at 3520 ± 145 B.C.) periods that corroborate geochemical data from Alexandria Bay. Pb concentrations in Maryut sediments show enrichments that mirror isotopic findings. The absence of contaminant Pb imprints within the sediments from the nearby Nile Canopic branch confirms that isotopic anomalies found in Alexandria Bay and Maryut Lagoon sediments are local and do not originate from long-distance transport of contaminant Pb associated with Nile suspended material and/or wind-derived aerosols. LIA in Alexandria sediment cores correspond to commonly mined Pb and Cu (copper) ores from Turkey (Black Sea region), Cyprus, Crete and the Oman Gulf. LIA substantiate the use of copper-based relics in the Alexandria region during the Pre and Early dynastic periods, and provide insights into metal trading within the Eastern Mediterranean during the Chalcolithic-Early Bronze Age transition, 6000 years ago.

    The floristic composition and species diversity of the germinable soil seed bank were studied in three different habitats (desert salinized land, desert wadi, and reclaimed land) in the Eastern Desert of Egypt. Moreover, the degree of similarity between the seed bank and the above-ground vegetation was determined. The seed bank was studied in 40 stands representing the three habitats. Ten soil samples (each 25 × 20 cm and 5 cm depth) were randomly taken per stand. The seed bank was investigated by the seedling emergence method. Some 61 species belonging to 21 families and 54 genera were identified in the germinable seed bank. The recorded species include 43 annuals and 18 perennials. Ordination of stands by Detrended Correspondence Analysis (DCA) indicates that the stands of the three habitats are markedly distinguishable and show a clear pattern of segregation on the ordination planes. This indicates variations in the species composition among habitats. The results also demonstrate significant associations between the floristic composition of the seed bank and edaphic factors such as CaCO3, electrical conductivity, organic carbon and soil texture. The reclaimed land has the highest values of species richness, Shannon-index of diversity and the density of the germinable seed bank followed by the habitats of desert wadi and desert salinized land. Motyka's similarity index between the seed bank and the above-ground vegetation is significantly higher in reclaimed land (75.1%) compared to desert wadi (38.4%) and desert salinized land (36.5%).

    Background/Aim: Microscopic colitis (MC) is diagnosed when a patient with chronic watery non-bloody diarrhea (CWND) has an endoscopically normal colon, but colonic biopsies show unique inflammatory changes characteristic of lymphocytic or collagenous colitis. MC is a disorder of unknown etiology. Studies comparing the prevalence of the disease in developing countries as compared to developed countries may shed more light on the possibility of a post-infectious etiology. Most data on the incidence and prevalence of MC are from developed countries where it accounts for 4-13% of cases of CWND. There are only a few reports from developing countries. Two studies from Peru and Tunis, with high prevalence of infectious gastroenteritis, revealed MC in 40% and 29.3% of cases of CWND, respectively. The aim of this study was to investigate the prevalence of MC in patients presenting with CWND in Egypt. Materials and Methods: A total of 44 patients with CWND of unexplained etiology who had undergone full colonoscopy with no macroscopic abnormalities between January 2000 and January 2010 were assessed retrospectively. Results: The histological appearance of MC was identified in 22 (50%) patients. Twelve (55%) patients were male and 10 (45%) female. Mean age was 40 years (range: 20-65 years). Twenty (91%) of MC cases had lymphocytic colitis and 2 (9%) had collagenous colitis. Conclusions: The prevalence of MC in Egyptian patients with CWND is high when compared to that in developed countries. MC mainly affects young and middle-aged patients and it is more commonly of the lymphocytic type. PMID:22064335

    Antioxidant activity and mineral composition were evaluated seasonally from spring to autumn 2010 in the three common seaweeds Ulva lactuca Linnaeus (Chlorophyta), Jania rubens (Linnaeus) J.V. Lamouroux and Pterocladia capillacea (S.G. Gmelin) Bornet (Rhodophyta). The antioxidant activity was measured with β-carotene, total phenol content and DPPH (2,2-diphenyl-1-picrylhydrazyl). Seaweeds were collected from the rocky site near Boughaz El-Maadya Abu-Qir Bay of Alexandria, Egypt. The results showed maximum increase of β-carotene in P. capillacea during summer. A significant increase in total phenolic content at P ⩽ 0.05 was found in the red alga (J. rubens) during summer. Also, U. lactuca showed the maximum antioxidant scavenging activity especially during summer. Minerals in all investigated samples were higher than those in conventional edible vegetables. Na/K ratio ranged between 0.78 and 2.4 mg/100 g, which is a favorable value. All trace metals exceeded the recommended doses by Reference Nutrient Intake (RNI). During summer season, it was found that Cu = 2.02 ± 0.13 and Cr = 0.46 ± 0.14 mg/100 g in U. lactuca and Fe had a suitable concentration (18.37 ± 0.5 mg/100 g) in P. capillacea. The studied species were rich in carotenoids, phenolic compounds, DPPH free radicals and minerals, therefore, they can be used as potential source of health food in human diets and may be of use to food industry.

    The degree to which local climatic variations, eustatic sea level fluctuations, and tectonic uplift have influenced the development of Quaternary marine and fluvial landforms and deposits along the Red Sea coast, Eastern Desert, Egypt was investigated using a combination of remote sensing and field data, age determinations of corals, and numerical simulations. False color composites generated from Landsat Thematic Mapper and SPOT image data, digital elevation models derived from stereophotogrammetric analysis of SPOT data, and field observations document that a {approximately}10-km-wide swath inland from the coast is covered in many places with coalescing alluvial fans of Quaternary age. Wadis cutting through the fans exhibit several pairs of fluvial terraces, and wadi walls expose alluvium interbedded with coralline limestone deposits. Further, three distinct coral terraces are evident along the coastline. Climatic, eustatic, and tectonic uplift controls on the overall system were simulated using a cellular automata algorithm with the following characteristics: (1) uplift as a function of position and time, as defined by the elevations and ages of corals; (2) climatic variations driven by insolation changes associated with Milankovitch cycles; (3) sea level fluctuations based on U/Th ages of coral terraces and eustatic data; and (4) parameterized fluvial erosion and deposition. Results imply that the fans and coralline limestones were generated in a setting in which the tectonic uplift rate decreased over the Quaternary to negligible values at present. During lowstands, wadis cut into sedimentary deposits; coupled with continuing uplift, fans were dissected, leaving remnant surfaces, and wadi-related terraces were generated by down cutting. Only landforms from the past three to four eustatic sea level cycles (i.e., {approximately} 300 to 400 kyr) are likely to have survived erosion and deposition associated with fluvial processes. 33 refs., 18 figs., 2 tabs.

    It has been suggested that nitrate and nitrite may play a role in the etiology of human oral cancer. We investigated whether salivary nitrate and nitrite and the activity of nitrate reductase (NRase) may affect the risk of oral cancer in Egypt, an area with high levels of environmental nitrosating agents. Levels of salivary nitrite (8.3 +/- 1.0 micrograms/ml) and nitrate (44 +/- 3.7 micrograms/ml) and activity of NRase (74 +/- 10 nmol/ml/min) were significantly (P < 0.05) higher in oral cancer patients (n = 42) compared to control Egyptian healthy individuals (n = 40, nitrite = 5.3 +/- 0.3 micrograms/ml, nitrate = 27 +/- 1.2 micrograms/ml, and NRase activity = 46 +/- 4 nmol/ml/min). The adjusted odds ratio (OR) and the 95% confidence intervals (C.I.) for risk of oral cancer, categorized by the levels of salivary nitrate and nitrite and NRase activity, showed a higher cancer risk associated with nitrite > 7.5 micrograms/ml (OR: 3.0, C.I.: 1.0-9.3), nitrite > 40 micrograms/ml (OR: 4.3, C.I.: 1.4-13.3) and NRase activity > 50 nmol/ml/min (OR: 2.9, C.I.: 1.1-7.4). Our findings suggest that increased consumption of dietary nitrate and nitrite is associated with elevated levels of salivary nitrite. Together with the increased activity of salivary NRase, these observations may explain, at least in part, the role of nitrate and nitrite in the development of oral cancer in individuals from an area with a high burden of N-nitroso precursors.

    North Africa has undergone drastic climatic changes over the past several hundred thousand years. The timing of humid intervals called pluvials was investigated by uranium-series disequilibrium dating of travertines from the Kurkur Oasis, Western Desert, Egypt. The youngest and best dated travertines (70-160 ka) are found in Wadi Kurkur and include spring and lacustrine units exposed as 2 to 3 m high terraces. Travertines having an age of approximately 191-220 ka are exposed by differential erosion as linear mounds produced by spring systems over fracture zones in ancient wadis. The oldest travertines, having ages >260 ka, are extensive, cap limestone units above the oasis, and were deposited in paludal and lacustrine environments. Oxygen isotope ratios were measured for the wadi travertines ({delta}{sup 18}O values ranging from 16.7 to 19.1{per_thousand} SMOW) and for spring mound travertines (18.5-20.5{per_thousand}). Equilibrium oxygen isotope fractionation calculations indicate that the Kurkur travertines were deposited from waters having {delta}{sup 18}O values similar to ancient Western Desert groundwaters ({approx} -11{per_thousand}). The ages of the travertines correspond to times of monsoonal maxima, eustatic sea level high stands and interglacial maxima. Rainfall producing these groundwaters (and travertines) was significantly fractionated during atmospheric transport, in contrast to modern meteoric waters (-2.09{per_thousand}), implying a distant source for the pluvial waters. Increased precipitation, recharge of Western Desert groundwaters, and resultant travertine deposition are interpreted to be consequences of Milankovitch insolation cycle forcing, through enhanced Atlantic and Indian Ocean monsoons during interglacial time periods.

    Neuroblastoma, an embryonal malignancy of the sympathetic nervous system, is the most frequent extracranial solid tumor The clinico-epidemiological features of neuroblastoma in infants and children were investigated between January 2005 and January 2010 at the Pediatric Oncology units of Mansoura, Zagazig, and Tanta University Children's Hospitals (Egypt). Of 142 cases of neuroblastoma, 10 were omitted from the study due to defective data. The median age of the patients was 30 months, with 75.8% aged ≥1 year and 24.2% aged <1 year at time of diagnosis. The male-to-female ratio was 1.06. Suprarenal glands were the most common primary tumor site (72.7%). The majority of the patients (76.7%) had stage IV disease. Favorable pathology was observed in 43.8% of patients, while 56.2% exhibited unfavorable pathology. The estimated survival rate of patients was 30.7±10.0%, and mean survival time was 24.2±5.2 months. The rate of mortality was 28.6% for patients aged <1 year, and 81.8% for those aged ≥1 year (P=0.005). For patients with favorable pathology, the rate of mortality was significantly lower (28.6%) compared with that of patients with unfavorable pathology (77.8%; P=0.049). Although the association between outcome and each of the primary tumor sites, children's oncology group risk and gender was statistically insignificant, a large effect size was identified between outcome and primary tumor site, as well as children's oncology group risk and a medium effect size was identified between outcome and gender. Additionally, an age of ≥1 year was associated with unfavorable pathology (P=0.024), stage IV disease (P=0.026) and a suprarenal primary tumor site (P=0.001). PMID:26622625

    Until the end of the 19th Century Science was not classified into different disciplines. The first woman named in the history of science was Merit Ptah (2700 BC) in Egypt's Valley of the Kings. In the new Egypt the first girl's school started in Cairo in 1873 and the first University in 1908. Only a few girls attended the University at that time, mainly studying the humanities. The first Egyptian woman physicist graduated in 1940 and received her PhD in nuclear physics in the USA. Nowadays the number of women in physics is increasing in all branches of physics, some of them are senior managers and others have been decorated with various prizes. In this talk some statistics will be given to show the percentage of women in physics in relation to other fields of science in Egypt. In Saudi Arabia the first girls' school started in 1964 and the first college for women, which was a section of King Abdul-Aziz University (where education is not mixed), started in 1975. I was the founder of the Physics Department of this women's section. Egyptians have played significant roles in teaching schoolchildren and university students of both sexes in all the Arab countries: Saudi Arabia, Sudan, Kuwait, Yemen, the Gulf States, Libya, Lebanon, Syria, and Jordan. But with respect to Algeria, Tunisia and Morocco, our role was limited, since classes are taught in French. Arab women living in the countries located east of Egypt still have many difficulties facing them, needing to overcome many technical, academic, and social problems, while women in the countries located west of Egypt have fewer problems. There were many problems in the early days of education in Egypt but the women of Egypt worked hard to gain the same rights as men and were able to pave the way for all Arab women. I myself met many difficulties in my early days. This talk will also describe the impact of the regional conference on Women in Physics in Africa and Middle East, which was held in Cairo in 2007.

  8. Changes in the epidemiology of plague in Egypt, 1899-1951

    The author of this article discusses the epidemiology of plague in Egypt from its reintroduction in that country in 1899 until 1951. Dealing first with the period 1899-1945, before the introduction of DDT, he notes that plague was first reported in the ports and then spread rapidly inland; in contrast with previous epidemics, the prevalence was greater in Upper than in Lower Egypt. By 1937 the whole of Lower Egypt had become free of the disease, which, however, persisted in endemo-epidemic form in Upper Egypt until 1941. The reasons for the slighter severity of this third plague pandemic in Egypt compared with the previous history of the disease there are discussed, particularly in connexion with the role played by rodents. Details of the number of rats captured and of flea indices are given for the years from 1937 onwards. In 1941 a scheme was introduced for the control of rats in river and canal craft in order to prevent the spread of plague inland from the ports. The details of this scheme are given, and the significant fact is noted that no case of plague was reported inland from 1941 to 1945 despite an outbreak during that time in the Suez Canal Zone. Turning to the period 1946-51, after the introduction of DDT, the author discusses the Alexandria epidemic of 1946-47, giving rat and flea counts and describing the control methods adopted, which included the use of poison baits and DDT. Dusting both persons and rat burrows with DDT has clearly resulted in a sharp decrease in flea indices, and the periodical use of DDT and Gammexane in port areas since 1950 has been shown to yield good results.

    Cattle, buffaloes, and sheep are the main sources of meat and milk in Egypt, but their productivity is thought to be greatly reduced by hemoprotozoan parasitic diseases. In this study, we analyzed the infection rates of Babesia bovis, Babesia bigemina, Theileria annulata, and Theileria orientalis, using parasite-specific PCR assays in blood-DNA samples sourced from cattle (n=439), buffaloes (n=50), and sheep (n=105) reared in Menoufia, Behera, Giza, and Sohag provinces of Egypt. In cattle, the positive rates of B. bovis, B. bigemina, T. annulata, and T. orientalis were 3.18%, 7.97%, 9.56%, and 0.68%, respectively. On the other hand, B. bovis and T. orientalis were the only parasites detected in buffaloes and each of these parasites was only found in two individual DNA samples (both 2%), while one (0.95%) and two (1.90%) of the sheep samples were positive for B. bovis and B. bigemina, respectively. Sequence analysis showed that the B. bovis Rhoptry Associated Protein-1 and the B. bigemina Apical Membrane Antigen-1 genes were highly conserved among the samples, with 99.3-100% and 95.3-100% sequence identity values, respectively. In contrast, the Egyptian T. annulata merozoite surface antigen-1 gene sequences were relatively diverse (87.8-100% identity values), dispersing themselves across several clades in the phylogenetic tree containing sequences from other countries. Additionally, the T. orientalis Major Piroplasm Surface Protein (MPSP) gene sequences were classified as types 1 and 2. This is the first report of T. orientalis in Egypt, and of type 2 MPSP in buffaloes. Detection of MPSP type 2, which is considered a relatively virulent genotype, suggests that T. orientalis infection may have veterinary and economic significance in Egypt. In conclusion, the present study, which analyzed multiple species of Babesia and Theileria parasites in different livestock animals, may shed an additional light on the epidemiology of hemoprotozoan parasites in Egypt.

    The Mediterranean coast in Egypt extends almost 900 km, the major part of which is bordered by sand dunes of different natures and types. Along the coastline between Alexandria and El-Alamein, a distance of some 100 km, the sand dunes represent a particular landscape with special characteristics and features, and consequently plants with particular attributes. In this area, the belt of sand dunes has developed immediately south of the shore and these dunes may rise up to 10 m in height and extend about 0·5-1·5 km inland from the shore. These dunes are famous as a habitat for the fig (Ficus carica L.) cultivation depending on the irregular rainfall. They also represent a landing station and a cross-road for birds such as quail migrating from Europe in the north. In the past, summer resort areas were confined to limited areas with few people, these same areas support the growth of some important plant species, for example, sand binders, medicinal and range plants. For more than two decades, there has been considerable socio-economic change and an open-door policy in the economy of the country has been adopted. One of the consequences of this change is that a great part of the coastal dune belt west of Alexandria till El-Alamein, has been subjected to destruction, due to the continuous construction of summer resort villages. These were built at a distance of about 100 m of the shoreline, extending 400-600 m inland and a breadth of 400 m or more along the shoreline. The area already covered by the dunes is now almost occupied by new buildings, gardens and other infrastructure. The consequences of these human activities are numerous and include impacts on the soil, water resources, the flora and the fauna, migrating birds, trends of the indigenous people, and the cultural environment. The present paper gives a concise environmental setting of the dune belt before the advent of the new activities, and the socio-economic and political attitudes which threaten the dunes

    The present study described a new species of the genus Echinocephalus that was isolated from the intestine of the common carp Cyprinus carpio inhabiting Burullus Lake, Kafr el-Sheikh Governorate, Egypt. Thirty-two out of 70 examined specimens (45.71 %) were found to be naturally infected. The adult male worms were elongated and measured 0.79-0.85 mm (0.81 ± 0.02) in length and 0.21-0.32 mm (0.28 ± 0.002) in width, while females reached 0.89-0.98 mm (0.9 ± 0.02) long and 0.25-0.38 mm (0.28 ± 0.002) wide. The reported species are investigated microscopically, genetically, and compared with previous related ones. The present study recorded this new nematode parasite as Echinocephalus carpiae with accession no. KC493258, inhabiting new host and locality records in Egypt. It is especially characterized by short body length, cephalic bulb with few (six to eight) multiple rows of spines, clear annulated cuticle, and new genetic sequences, which identify the paraphyly of Gnathostomatinae.

    The objective of this paper is to provide a taxonomic appraisal of the melicharids from Egypt, based on specimens previously collected by different authors and on specimens newly collected by the first author of this paper, all belonging to the genus Proctolaelaps Berlese. A new species, Proctolaelaps gizaensis n. sp., is described, thus raising to six the number of Proctolaelaps species recorded from Egypt. Complementary descriptions of the following species are also provided: Proctolaelaps aegyptiacus Nasr, 1986; Proctolaelaps holoventris Moraes, Britto, Mineiro & Halliday, 2016; Proctolaelaps pygmaeus (Müller, 1859); Proctolaelaps drosophilae Karg, Baker & Jenkinson, 1995 and Proctolaelaps regalis De Leon, 1963. The latter two species were not found in Egypt, but they are related to the new species described here. They were re-described based on the type specimens from Europe and North America. A dichotomous key is given to help the separation of the Proctolaelaps species concluded to be found in Egypt. PMID:27615986

    The present paper refers to the identification of phytoseiid specimens newly collected by the first author of this paper and her collaborators, as well as to the examination of type specimens of species previously described from Egypt. The taxonomy of phytoseiid mites has been studied in Egypt since 1967. Until now, 78 nominal species have been recorded, of which 60 are valid. One of those species, Phytoseius plumifer (Canestrini & Fanzago), appears to be based on an incorrect record. An additional species (Typhlodromus hellei Hassan, Afifi & Nawar), described from Egypt, is not sufficiently characterised to allow its correct generic classification and the determination of its validity. Eight new records are reported in this paper, including two new species, Proprioseiopsis ismailiaensis n. sp. and Typhlodromus (Anthoseius) fayoumensis n. sp., which are described. Complementary descriptions of 11 known species are given. An updated survey of all species reported from Egypt and a taxonomic key to separate them are also presented. Six new synonymies are proposed.

    .62, p>0.05) did not seem to have a significant association among the examined dogs. Enteric parasitic infection was reported in 31/150 human stools (20.67%). Students were the most affected groups (37.14%), followed by nomadic people (24%), house wives (20%), house guarders and military workers (12%, each), and employees (10%). The identified parasites were Cryptosporidium spp. (9.33%), Ascaris lumbercoides (3.33%), Heterophyes spp. and Ancylostoma spp. (2.66%, each) and Paragonimus spp. and Hymenolepis nana (1.33%, each). Toxocara IgG antibodies were detected in 36/150 (24%) serum samples investigated. Toxocara IgG antibodies were more prevalent in males (26.66%) than females (20%). Seroprevalence was highest (17/35, 48.57%) in 7-15 years old (COR=6.93, 95% CI=1.75-27.43, p=0.006). Seroprevalence values for T. canis antibodies were higher in those; raising dogs (29.85%), eating raw vegetables (25.21%) and not washing hands before meals (25.45%). T. canis antibodies were detected in 25% of those contacted with soil compared to 30% of those did not. Students were mostly affected (34.29%), followed by nomadic people (32%), house guarders (28%), housewives (20%), military workers (13%), and employees (10%). Conclusion: Detection of enteric parasites in dogs and humans in Egypt substantiates the role posed by dogs in transmitting zoonotic parasites to humans and knock an alarm for common sources of infection for humans and dogs. Common sources may be infected fish or contaminated vegetables that are consumed by dogs or humans or even infected rodents that may contaminate their feed. This pilot study necessitate the need for similar studies and tracing such infection in fish, vegetables, rodent that may be responsible for infecting humans and dogs in order to understand the epidemiology of zoonotic parasitic infection transmitted from dogs to humans.

    Soil and groundwater contamination is one of the important environmental problems at petroleum-related sites, which causes critical environmental and health defects. Severe petroleum hydrocarbon contamination from coastal refinery plant was detected in a shallow Quaternary sandy aquifer is bordered by Gulf in the Northwestern Gulf of Suez, Egypt. The overall objective of this investigation is to estimate the organic hydrocarbons in shallow sandy aquifers, released from continuous major point-source of pollution over a long period of time (91 years ago). This oil refinery contamination resulted mainly in the improper disposal of hydrocarbons and produced water releases caused by equipment failures, vandalism, and accidents that caused direct groundwater pollution or discharge into the gulf. In order to determine the fate of hydrocarbons, detailed field investigations were made to provide intensive deep profile information. Eight composite randomly sediment samples from a test plot were selected for demonstration. The tested plot was 50 m long × 50 m wide × 70 cm deep. Sediment samples were collected using an American auger around the point 29° 57' 33″ N and 32° 30' 40″ E in 2012 and covered an area of 2,500 m(2) which represents nearly 1/15 of total plant area (the total area of the plant is approximately 3.250 km(2)). The detected total petroleum hydrocarbons (TPHs) were 2.44, 2.62, 4.54, 4.78, 2.83, 3.22, 2.56, and 3.13 wt%, respectively. TPH was calculated by differences in weight and subjected to gas chromatography (GC). Hydrocarbons were analyzed on Hewlett-Packard (HP-7890 plus) gas chromatograph equipped with a flame ionization detector (FID). The percentage of paraffine of the investigated TPH samples was 7.33, 7.24, 7.58, 8.25, 10.25, 9.89, 14.77, and 17.53 wt%, respectively.

    Migratory (particularly aquatic) birds are the major natural reservoirs for type A influenza viruses. However, their role in transmitting highly pathogenic avian influenza (HPAI) viruses is unclear. Egypt is a "funnel" zone of wild bird migration pathways from Central Asia and Europe to Eastern and Central Africa ending in South Africa. We sought to detect and isolate avian influenza viruses in migratory birds in Egypt. During September 2003-February 2009, the US Naval Medical Research Unit Number 3, Cairo, Egypt, in collaboration with the Egyptian Ministry of Environment, obtained cloacal swabs from 7,894 migratory birds captured or shot by hunters in different geographic areas in Egypt. Samples were processed by real-time reverse transcriptase PCR for detection of the influenza A matrix gene. Positive samples were processed for virus isolation in specific-pathogen-free embryonated eggs and isolates were subtyped by PCR and partial sequencing. Ninety-five species of birds were collected. Predominant species were Green-Winged Teal (Anas carolinensis; 32.0%, n=2,528), Northern Shoveler (Anas clypeata; 21.4%, n=1,686), and Northern Pintail (Anas acuta; 11.1%, n=877). Of the 7,894 samples, 745 (9.4%) were positive for the influenza A matrix gene (mainly from the above predominant species). Thirteen of the 745 (1.7%) were H5-positive by PCR (11 were low-pathogenic avian influenza and two were HPAI H5N1). The prevalences of influenza A was among regions were 10-15%, except in Middle Egypt (4%). Thirty-nine influenza isolates were obtained from PCR-positive samples. Seventeen subtypes of avian influenza viruses (including H5N1 and H7N7) were classified from 39 isolates using PCR and partial sequencing. Only one HPAI H5N1 was isolated in February 2006, from a wild resident Great Egret (Ardea alba). No major die-offs or sick migratory birds were detected during the study. We identified avian influenza virus subtypes not previously reported in Egypt. The HPAI H5N1 isolated

    Worldwide, the incidence and mortality rates of childhood cancers differ. The study of incidence patterns and survival rates in childhood malignancies is important in aiding in the planning of treatment centers and in obtaining further information with regard to the etiology. Few studies have investigated the survival in cases of childhood solid tumors in Egypt. The aim of the current study was to evaluate the patterns, frequency and outcome of solid tumors and lymphomas in children admitted to and followed up at the Pediatric Oncology Department of Zagazig University Hospital (Zagazig, Egypt) over a duration of 5 years (January 2004 to December 2008). A retrospective study was conducted, which included 155 children with solid tumors and lymphomas. The medical records were reviewed and the relevant data collected, in particular, those concerning demographic, clinical, histopathological, laboratory and imaging data as well as the treatment plans and outcomes. The mean age of patients was 5.6±3.04 years at diagnosis. The patients comprised 94 males and 61 females. Non-Hodgkin lymphoma (NHL) was the most common tumor type, followed by neuroblastoma (31.0 and 29.0%, respectively). When patients were stratified in terms of age (<5, ≥5 but <10, and ≥10 years), the <5-years-of-age group exhibited the greatest number of patients. Fever, pallor and pain were the most frequent initial clinical presentations among the patients and stage II was the most common stage (39.1%) followed by stage IV, III and I (35.0, 20.3 and 5.6% respectively). The overall 5-year survival rate in the study group was 66.7%. The survival rate was significantly higher in patients with Wilm’s tumor and Hodgkin lymphoma, followed by NHL (92.0, 88.0 and 72.0%, respectively; P<0.001), while the mortality rate was significantly higher in patients with neuroblastoma (P<0.001). In conclusion, NHL and neuroblastoma were the most common tumors; the survival rates were higher in patients with Wilm

    The present study evaluated the presence of specific antibodies against Besnoitia besnoiti in cattle and water buffalo (Bubalus bubalis) in Egypt. Sera from cattle (n = 216) and water buffaloes (n = 133) collected from five different provinces of Egypt (Behera, Alexandria, Assuit, Gharbia, and Matrouh) were analyzed. Testing for B. besnoiti antibodies by PrioCHECK® Besnoitia Ab 2.0 ELISA initially identified 13.75 % (48 out of 349) of individual sera as positive at the manufacturer's suggested cutoff threshold, 15 percent positivity (PP). Statistically significant associations between B. besnoiti prevalence, species, sex, age, and geographical distribution were observed. Seropositive animals were distributed in all of the provinces from which animals were sampled except Gharbia province. Assuit province showed the highest percentage of infection (30.76 %) followed by Matrouh, Alexandria, and Behera provinces (25, 16.29, and 9.6 %, respectively). The highest infection rate of B. besnoiti was significantly higher in cattle (17.13 %) than in water buffaloes (9.02 %). Positive cases were observed in all age categories. While the highest infection rate (17.13 %) was recorded in the age group 5-10 years followed by the age group 1-5 years (15.38 %), and only one positive case (1.58 %) was recorded in the age group less than 1 year. The highest infection rate of B. besnoiti infection was recorded in the female animals (14.95 %) followed by the male animals (8.33). This is the first report on the detection of B. besnoiti in cattle and water buffaloes in Egypt.

    Although high concentrations of trace organic pollutants were recorded along the Egyptian Mediterranean Coast and its corresponding coastal wetlands, no published data are available for the levels of phenolic compounds. Thus, this work aimed to investigate the levels of phenolic compounds in sediments of a heavily polluted coastal wetland (Lake Maryut, Egypt). For that purpose, a method was optimized for the extraction and detection of chlorophenols, methylphenols, and nitrophenols in sediments using GC-MS. Sediments were extracted with 0.1 M NaOH/methanol by sonication. Cleanup of sediment extracts using liquid-liquid extraction and SPE was found important to remove most of the interfering co-extracts. The proposed analytical methodology was validated by analysis of matrix spikes. Detection limits were 0.063-0.694 μg/kg dw for sediments. Good recoveries (70-110%) and precision values (RSD < 20%) were obtained from the fortification experiments at the parts per billion level in sediments. The method was applied to investigate the level of contamination with phenols in 19 sediment samples from Lake Maryut. Results revealed that higher concentrations were observed in the main basin (MB) of Lake Maryut affected by the discharge of effluents from a primary wastewater treatment plant, direct discharge of industrial effluents, domestic wastes, and agricultural effluents from Qalaa Drain (QD). Chlorophenols (CPs) were the major group detected in the lake sediments followed by methylphenols (MPs) and nitrophenols (NPs). CPs were dominated by 2-, 4-, and 3-chlorophenols. Concentrations of CPs were higher at the north and northwestern parts of the MB indicating the influence of industrial effluents discharged into the lake. On the other hand, higher concentrations of NPs were observed at the south and southwestern parts of the MB, which is subjected to the discharge of agricultural and domestic effluents via QD. Results of the risk assessment revealed that phenol, cresols

    Background There is a little or no data available on the natural Babesia bovis (B. bovis) infection in water buffaloes (Bubalus bubalis) comparing to the available one for cattle. This study was conducted to investigate the natural B. bovis infection in water buffaloes in comparison to crossbred cattle under field conditions in Egypt. Methods: A total of 35 buffaloes and cattle were clinically and laboratory investigated from March to June 2008. Twenty-nine buffaloes and cattle out of 35 were naturally infected with B. bovis and showed signs of bovine babesiosis. Three cows and three buffaloes showed no clinical signs and were free from external, internal, and blood parasites served as control group. Results: Babesia bovis-infected cattle showed typical signs of bovine babesiosis while B. bovis-infected buffaloes showed a milder form (less severe) of the clinical signs. Advanced cases of cattle showed dark brown to dark red (coffee-color) urine, hemoglobinuria and nervous manifestations while these manifestations were not detected in the infected buffaloes. Hematological changes in both species however, these changes were less significant in buffaloes than those reported in cattle. Conclusion: This paper documents the first description of natural B. bovis infection in water buffaloes which were found to be more likely to be tolerant than cattle to the natural clinical infection with B. bovis and its subsequent haematological changes. Our finding may lead to a better understanding of the disease pattern of B. bovis infection under field conditions in buffaloes. PMID:25629060

    This investigation covered a survey of scale insects and mealy bugs infesting ten growing species of deciduous fruit trees in three localities in Alexandria govemorate. These localities were Merghem, Burg El-Arab, and El-Nahda about 50 Km. West of Alexandria under both rain-fed and irrigation system conditions. The common inspected fruit trees were fig, white mulberry, pomegranate, apple, pear, apricot, European plum, peach, almond, and persimmon. It was shown that a group of twenty scale insects and meaty bug species pertaining to fifteen genera belonging to six families of the super family: Coccoidea were collected and identified during the elapsing period from January to December, 2004. Among these species, Diaspidiotus perniciosus (Comstock) was recorded for the first time in Egypt. In the present study, many insect and non-insect parasitoids and predators were also found associated with these scale insects and mealy bugs on deciduous fruit trees in the three concerned localities throughout this investigation. These natural enemies were identified and recorded.

    The effect of vegetation cover on climatic change has not yet observed in Egypt. In the current study, Ismailia Governorate was selected as a case study to assess the impact of the vegetation cover expansion on both land surface and air temperature during twenty-eight years from 1983 to 2010. This observation site was carefully selected as a clear example for the highly rate of reclamation and vegetation expansion process in Egypt. Land Surface Temperature (LST) that were extracted from NOAA/AVHRR satellite data and air temperature (Tair) data that were collected from ground stations, were correlated with the expansion of vegetation cover that was delineated using Landsat TM and Landsat ETM+ data. The result showed that (LST) decreased by about 2.3°C while (Tair) decreased by about 1.6°C with the expansion of the cultivated land during twenty-eight years.

    The level of natural radioactivity in soil of 30 mining samples collected from six locations in southern Egypt was measured. Concentrations of radionuclides in samples were determined by gamma-ray spectrometer using HPGe detector with a specially designed shield. The obtained results of uranium and thorium series as well as potassium (K-40) are discussed. The present data were compared with data obtained from different areas in Egypt. Also, a solid state nuclear track detector SSNTD (Cr-39) was used to measure the radon concentration as well as exhalation rate for these samples. The radon concentrations were found to vary from 1.54 to 5.37 Bq/kg. The exhalation rates were found to vary from 338.81 to 1426.47 Bq/m2d. The values of the radon exhalation rate are found to correspond with the uranium concentration values measured by the germanium detector in the corresponding soil samples.

  5. International financial institutions and health in Egypt and Tunisia: change or continuity?

    The revolutions in Egypt and Tunisia appeared to herald a re-casting of International Monetary Fund and World Bank policy across the region. Public pronouncements by the heads of both institutions in the months following February 2011 acknowledged flaws in their approach to macroeconomic advice, against a background of worsening socioeconomic indicators, widespread youth unemployment, and widening health inequalities. Evidence on the ground, however, suggests continuity rather than change in international financial institution policies in Egypt and Tunisia, notwithstanding the emergence of a powerful new player-the European Bank for Reconstruction and Development. In the long term, new electoral realities and hardening public opposition in both countries seem likely to force a fundamentally different relationship between regional governments and the major international financial institutions than existed before 2011.

    Stable isotope and tritium analyses of shallow ground waters in the Eastern Desert of Egypt showed that the waters were derived largely by evaporation of regional precipitation and at least partly from precipitation in the past 45 y. To estimate the ground water recharge rate, we developed an integrated hydrologic model based on satellite data, geologic maps, infiltration parameters, and spatial rainfall distribution. Modeling indicated that during a severe 1994 storm, recharge through transmission loss in Wadi El-Tarfa was 21% of the precipitation volume. From archival precipitation data, we estimate that the annual recharge rate for the El-Tarfa alluvial aquifer is 4.7 x 10{sup 6} m{sup 3}. Implications for the use of renewable ground waters in arid areas of Egypt and in neighboring countries are clear.

    In a previous analysis of the country of origin of papers published in Naunyn-Schmiedeberg's Archives of Pharmacology, a major shift toward contributions from emerging market countries, was noticed in comparison of 2010 to 2001 publications. Repeating such analysis for 2012 publications in the journal confirmed this trend. An interesting new trend was the emerging presence of papers from a variety of Islamic countries including Egypt. Based on this trend, we shortly review the history and current structure of pharmacology in Egypt. It appears that the presence of Egyptian pharmacology in international journals including pharmacology journals has sharply been increasing over the last two decades. Challenges for a continuation of this encouraging trend are being discussed.

    Raw buffalo milk samples from the agroindustrial zone in upper Egypt were analyzed for the presence of organochlorine and organophosphorus pesticides using gas chromatography-mass spectroscopy. Five organochlorine pesticides namely, alachlor, dieldrin, hexachlorobenzene, lindane and methoxychlor and three organophosphorus pesticides chlorpyrifos, malathion, and parathion-methyl were detected in the milk samples. In 44% of the samples, the concentrations of lindane and malathion residues exceeded tolerance levels set by the European Commission (EC) in 2008. In addition, the concentrations of chlorpyrifos, methoxychlor, and hexachlorobenzene residues exceeded the 2008 EC maximum residual limits (MRLs) by 33, 66, and 88% of the examined samples, respectively. However, the levels of alachlor, dieldrin, and parathion-methyl residues were below EC MRLs. The results of this study confirm the risks of pesticide residues exposure that threaten consumer health in Egypt. Thus, we recommend that pesticide residue monitoring programs be instituted in all the developing countries.

    Little is known on the diversity and public health significance of Echinococcus species in livestock in Egypt. In this study, 37 individual hydatid cysts were collected from dromedary camels (n=28), sheep (n=7) and buffalos (n=2). DNA was extracted from protoscoleces/germinal layer of individual cysts and amplified by PCR targeting nuclear (actin II) and mitochondrial (COX1 and NAD1) genes. Direct sequencing of amplicons indicated the presence of Echinococcus canadenesis (G6 genotype) in 26 of 28 camel cysts, 3 of 7 sheep cysts and the 2 buffalo derived cysts. In contrast, Echinococcus granulosus sensu stricto (G1 genotype) was detected in one cyst from a camel and 4 of 7 cysts from sheep, whereas Echinococcus ortleppi (G5 genotype) was detected in one cyst from a camel. This is the first identification of E. ortleppi in Egypt.

    Though rain storms are infrequent in Egypt, which is normally a rainless country, some Ancient Egyptian texts give accounts of violent storms and rains. Actually, even small amounts of rain in that area could cause huge impact, as none of the water was absorbed by soil, and, running off, it could create dangerous torrents. The Tempest stele, circa 1550 BC, recounts a highly destructive storm happened during the reign of Ahmose I, the king of Egypt's 18 dynasty. The catastrophy is described in details, including the specific noise, overall darkness, torrent so that no torch could be lit. Many houses were washed into the river, temples, tombs and pyramids damaged and collapsed. The stele commemorates the restoration works made by the king who was able to cope with this great disaster and "re-establish the Two Lands". Some egyptologists believe that this event is related to the Minoan eruption of Thera, but this is unlikely given the description in the stele.

    Dracaena sanderiana, of the family Liliaceae, is among the ornamental plants most frequently imported into Egypt. Typical anthracnose symptoms were observed on the stems of imported D. sanderiana samples. The pathogen was isolated, demonstrated to be pathogenic based on Koch’s rule and identified as Colletotrichum dracaenophilum. The optimum temperature for its growth ranges from 25 to 30 °C, maintained for 8 days. Kemazed 50% wettable powder (WP) was the most effective fungicide against the pathogen, as no fungal growth was observed over 100 ppm. The biocontrol agents Trichoderma harzianum and Trichoderma viride followed by Bacillus subtilis and Bacillus pumilus caused the highest reduction in fungal growth. To the best of our knowledge, this report describes the first time that this pathogen was observed on D. sanderiana in Egypt. PMID:27222738

    Climate change is an emerging global issue. It is expected to have significant impacts both in Egypt and around the world. Thus, the country is in need for taking action to prepare for the unavoidable effects of climate change, including the increase in water stress, the rise in sea level, and the rapidly increasing gap between the limited water availability and the escalating demand for water in the country. Also, weather and climate play a significant role in people's health. Direct impacts of climate change on the Egyptians public health may include also increased prevalence of human parasitic diseases. Climate could strongly influence parasitic diseases transmitted through intermediate hosts. The present work reviews the future of such parasitic diseases in the view of the current available evidence and scenarios for climate change in the Egypt.

    In Egypt, kin relations have been governed by a patriarchal contract, which defines expectations for intergenerational support along gendered lines. Social changes may be disrupting these customs and bringing attention to the ways gender may influence intergenerational support in rapidly changing contexts. Using data from 4,465 parent–child dyads in Ismailia, Egypt, we examined whether intergenerational material transfers favored women over men and whether gaps in needs and endowments accounted for gender differences in transfers. Fathers gave children money and goods more often than did mothers; mothers received material transfers from children more often than did fathers. Compared to sons, daughters made transfers to parents less often and received transfers from parents more often. We found residual advantages to mothers and daughters, even adjusting for differential needs and endowments. Findings corroborate persistent norms of gender complementarity, patrilocal endogamy, and reciprocation for women’s caregiving, despite changes that have threatened patriarchal rules of exchange.

  16. International financial institutions and health in Egypt and Tunisia: change or continuity?

    The revolutions in Egypt and Tunisia appeared to herald a re-casting of International Monetary Fund and World Bank policy across the region. Public pronouncements by the heads of both institutions in the months following February 2011 acknowledged flaws in their approach to macroeconomic advice, against a background of worsening socioeconomic indicators, widespread youth unemployment, and widening health inequalities. Evidence on the ground, however, suggests continuity rather than change in international financial institution policies in Egypt and Tunisia, notwithstanding the emergence of a powerful new player-the European Bank for Reconstruction and Development. In the long term, new electoral realities and hardening public opposition in both countries seem likely to force a fundamentally different relationship between regional governments and the major international financial institutions than existed before 2011.

    The dynamics of the spreading, and the identity of a virulent epidemic, similar to bubonic plague or typhus, which hit Ancient Egypt in the middle of the Bronze Age, are hereby presented. Documented in medical papyri as well as archaeological findings, and re-echoed in biblical texts, a plague entered Egypt's main harbor, Avaris, around 1715 BC. As a result, the country was severely weakened at a time when it was already facing serious sociopolitical issues: crumbling central government, immigration, foreign influence, and the rise in power of the army and of warlords. The Hebrews, one of the ethnic groups within the Avaris area, appeared immune amidst the devastation of the plague. This immunity was key to identify the etiological agent of the epidemic: Francisella tularensis, the Gram-negative bacterium passed by ticks, and that causes tularemia. The disease manifests itself as either an ulceroglandular or a typhoid syndrome, accounting for its similarity with bubonic plague and typhus. Cellular immunity provides the main defense against F. tularensis, and is achieved through continuous contact with avirulent strains of the bacterium. Urban dwellers of Avaris, who had a limited contact to animals, would have been defenseless against the virulent strains, unlike the Hebrews, who lived off sheep and other animals. Attempting to consolidate Egypt's central government in the aftermath of the tularemia epidemic, led among others to the internment of the Hebrews in labor camps. The repressive measures against the Hebrews left traces in the subsequent archaeological layer (stratum F) at Avaris. As a corollary, the enslavement would set the stage for the exodus of the Hebrew community from Egypt at a later time.

    Proteopithecus sylviae is an archaic anthropoid from the late Eocene quarry L-41, Fayum Province, Egypt. The dentition of Proteopithecus is very primitive and does not closely resemble that of other, better known, primates from the Fayum (e.g., parapithecids and propliopithecids). The dental morphology, much of which is described herein, shows a platyrrhine-like level of organization, suggesting that P. sylviae may occupy a position near the base of the modern anthropoid radiation.

    Background Injury is a growing public health problem worldwide. Deaths due to injuries account for 10% of the world’s mortality. More than 90% of the world’s injury deaths occur in low and middle income countries. In Egypt, injury is a hidden epidemic and its related deaths are misclassified due to lack of accurate national data. Furthermore, as a research problem it has also been largely ignored in developing countries. Objectives To determine the pattern and trend of injury from January 2002 to December 2009 among attendants at trauma unit in Assiut university hospital in Upper Egypt. Patients and Methods A descriptive retrospective study was conducted at the trauma unit in Assiut university hospital in Upper Egypt. All registered injuries during January 2002 to December 2009 were included in the study. Results During January 2002 to December 2009, 213835 injured cases were admitted to the trauma unit. The number of attendants increased every year from 9.3% from the total cases in all study period in 2002 up to 15.3% in 2009 with a statistically significant difference (P = 0.000). Young adults aged 20 - 29 years were the most common group affected by injuries (22.2%). Male to female ratio was 3:1. Falls represent one half of injuries (49.6%) from all attended cases, followed by exposure to inanimate mechanical forces (19.5%) and transport accidents (18.3%). Falls were ranked as the leading cause of injuries, while transport accidents were the second cause in 2007 - 2009. Conclusions Trauma in Upper Egypt is an under-recognized problem, which requires prioritized attention. Increasing the awareness of community, making policies and establishment of a trauma system are important to decrease the burden of injuries. PMID:27626001
