  2. Relationship between sediment morphology and oil pollution along the Suez Canal beaches, Egypt

    International Nuclear Information System (INIS)

    In this study, marine surface sediments are collected from nine locations along the Suez Canal in order to investigate the relationship between the morphology of sands in the studied beaches and pollution by oil. Basically, the studied samples were analyzed by three techniques: grains-size analysis, microscopic examination, and gas chromatographic (GC) analysis. This study concluded that medium sand is the major class represented in the studied marine sediments. Pollution in these sand grains increases in the irregular grains more so than in the more rounded grains. Also, deep surface points, pitting, and fissures are considered to be good sites to precipitate oil contamination. Also, the presence of iron oxides may be taken as evidence for tanker ballast washings. The heavy fraction (zircon) shows more contamination than the light fraction (quartz) in these samples. Finally, GC profiles have shown two types of samples: one typical of weathered or highly weathered crude oil patterns and the other for samples with very highly weathered profiles. The relationship obtained between morphology studies and both oil content and GC chromatogram profiles indicates that all of the studied locations are suffering from pollution of oil that is spilled while shipping petroleum through the Suez Canal

They were surveyed through a self-administered questionnaire based on items from the Dentist Satisfaction Survey (DSS questionnaire, which included 29 questions covering items related to the overall satisfaction level and work environment factors; answers were reported on 5 point Likert scale. Results: The mean score of overall job satisfaction among studied dentists was 3.24 out of 5. As regards work environment factors, the most satisfying aspect was patient relations (3.71 and the least was personal time (2.71. Multiple regression analysis model verifi ed that patient relations, value of income, personal time, staff, and training opportunities accounted for 36% of variation in overall job satisfaction score. The majority of the variance was explained by patient relations. Conclusions: This study suggests that patient relations, perception of income, personal time, staff, and specialty training are important work environment factors for job satisfaction among the dentists. These fi ndings might help policy makers to design plans to increase the level of job satisfaction among dentists at their workplaces.

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

    International Nuclear Information System (INIS)

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

El conflicto que opone a Egipto a una alianza formada por Gran Bretaña, Francia e Israel se produce a consecuencia de la nacionalización del Canal de Suez por el dirigente egipcio Gamal Abdel Nasser. Esta alianza entre dos estados europeos e Israel respondió a intereses comunes: económicos, comerciales y políticos. Durante el curso del mes que siguió a la nacionalización del Canal, un acuerdo secreto fue firmado en Sèvres, en las afueras de Paris, en el cual se selló la cooperación militar de Gran Bretaña, Francia e Israel contra Egipto.______________________ABSTRACT:The Suez Crisis (the Suez War, the Kadesh Operation, or the Suez Campaign is a war on Egyptian territory what started with a tripartite aggression by Great Britain, France and Israel against Egypt in 1956, after the nationalization of the Suez Canal by Egyptian leader Gamal Abdel Nasser. The war plot against Egypt was hatched towards the end of October 1956 in a secret meeting in Sèvres, near Paris. The discussions culminated in the signature of the Protocol of Sèvres.

  8. Emergency preparedness and response in case of a fire accident with UF6 packages traversing the Suez Canal

    International Nuclear Information System (INIS)

    Egypt has a unique problem, the Suez Canal. Radioactive cargo passes regularly through the canal carrying new and spent reactor fuel. There are also about 1000 metric tonnes of uranium hexafluoride (UF6) passing through the canal every year. In spite of all the precautions taken in the transport, accidents with packages containing UF6 shipped through the Suez Canal may arise, even though the probability is minimal. Such accidents may be accompanied by injuries to or death of persons and damage to property including radiation and criticality hazards and high chemical toxicity, particularly if the accident occurred close to one of the three densely populated cities (Port Said, Ismailia and Suez), which are located along the west bank of the Suez Canal. The government of Egypt has established a national radiological emergency plan in order to deal with any radiological accidents which may arise inside the country. This paper considers the effect of a fire accident to industrial packages containing UF6 on board a cargo ship passing along the Suez Canal near Port Said City. The accident scenario and emergency response actions taken during the different phases of the accident are presented and discussed. The paper highlights the importance of public awareness for populations located in densely populated areas along the bank of the Suez Canal, in order to react in a timely and effective way to avoid the toxic and radiological hazards resulting from such a type of accident. The possibility of upgrading the capabilities of civil defence and fire-fighting personnel is also discussed (author)

    <正>The Suez Canal,attached route alternatives with traffic flows and areas are described and theoretical break-even points derived. Logistically,route selection depends on relative distances,the level of spot rates and canal dues,the sensitivity to change growing with rising rate levels.The connection is diluted by the canal /pipeline owners’ price differentiation and the charterers’ capital costs;interest on cargo and change of its value during transit.Ship-owners are largely neutral to route choice as long as rates and main cost items are directly related to distance.

  10. Rift offsets, Gulf of Suez, Egypt

    1988-02-01

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

    British Gas, as operator for its partners, Yukong Ltd., and Union Pacific Petroleum Suez Ltd., recently discovered the Warda field in the Gulf of Suez in November 1990. Discovery well Hb78-2, located 4 km off the mouth of the Wadi Araba on the west side of the north-central Gulf of Suez, reached a total depth of 8,400 ft in Nubia clastics. Oil was tested in the Hb78-2 from five separate clastic intervals at a cumulative flow rate of approximately 7,000 BOPD of 20-24{degree} API with no water. Currently, an appraisal well program is underway to extend the limits of the field. This significant new-field discovery is located in a part of the Suez basin that previously considered to have limited oil potential. Geophysical assessment of the structure used exploration 3-D seismic coverage and concurrently acquired potential-fields datasets. The Warda structure at Kareen-Rudeis levels is a broad four-way closure, trending northwest-southeast, which drapes over older pre-Miocene tilted fault blocks. The Warda structure lies downthrown to a major Clysmic shoulder fault and is bounded on the northeast by another Clysmic down-to-the-basin normal fault. Cross faulting is noted at the deeper levels, and particularly influences the rift boundary faults. According to burial-history modeling, oil generation occurred within 4-5 million years after the Eocene-Senonian carbonate source rocks achieved onset of oil generation at a birthline of 10,000-11,000 ft subsea. The Cretaceous-Carboniferous Nubia sandstones apparently have acted as a conduit for oil migration from the adjacent Lagia hydrocarbon kitchen a few kilometers to the northeast.

    The biogeography of macrobenthic communities with large-scale differences in species distribution and abundance was studied along the eastern and western coastal regions of the Gulf of Suez to indicate biodiversity of benthos in relation to the prevailing en-virunmental conditions.In general,benthos have a wide variety of species of mainly polychaet worms,crustaceans,bivalves,and other bottom invertebrates hying in burrows in/or on the sediment surface.Coastal development clearly affects the ecosystem after the construction of coastal projects.The highest values of benthic diversity,evenness,richness and dominance are found at the Gulf of Suez (WG 1,WG 3),Ras Gharib ( WG 7,WG 8) and Ras Shukier (WG 9a) by contrast to others.The abundance of macrobenthic organsims along the coasts of Gulf of Suez can be arranged in the following sequence:other groups (34%) greater than crustaceans (25%) greater than polychaetes (22%) greater than molluscs (17%) greater than echinoderms (2%).The biomass of benthic assemblages at different sampling sites can also be ranked as follows:echinoderms (52%) greater than mol-luscs (27%) greater than crustaceans (16%) greater than polychaetes (2%) greater than other groups (3%).Some benthic groups or species indicated a distinctive correlation to pollution sources in the marine ecosystem which obviously increased in the coastal areas due to the extension of the coastal development.These activities needed regular information to establish database for the biology and distribution of marine benthic communities.The density and diversity of benthos are significantly affected by eu-trophication at Ain Sukhna,whereas the benthos in the open Gulf of Suez do not seem to be adversely affected by pollution.

    Detailed subsurface studies of the northern part of the Suez Rift and adjacent areas indicate the superposition of two different episodes of deformation. During the earlier (Late Cretaceous) phase of deformation, folds with NE-SW oriented axes were formed in northern Egypt as a result of convergence between Africa and Eurasia and the closure of the Neotethys. During the later (early Miocene) deformation, NW-oriented normal faults were formed as a result of the opening of the Suez Rift. Borehole data have shown that a belt of NE en echelon folds with NE-SW axes exists in the subsurface in the northernmost part of the rift, between Ayun Musa and the Sukhna-1 well, south of Gebel Ataqa. This fold belt represents the SW continuation of the en echelon folds exposed in the Mitla Pass, to the NE of the rift. Another pre-rift structure is the offshore extension of the Wadi Araba structure as a SE-facing monocline. This offshore structure also represents the continuation of the Gebel Somar structure, on the eastern shoulder of the Suez Rift. The Gebel Somar and Wadi Araba structures represent the southernmost pre-rift folds in northern Egypt. Pre-rift folds in the study area stood high above sea-level during the Palaeocene and early Eocene. Upper Cretaceous and/or older rocks in the cores of these folds were later uncomfortably covered by middle Eocene rocks. The presence of Late Cretaceous folds should be taken into consideration when exploring for hydrocarbons in this part of the Suez Rift. Borehole data in NE Egypt also indicate the presence of Late Cretaceous folds underneath the almost flat-lying Tertiary rocks in the northern part of the Eastern Desert. These folds are considered to be potential hydrocarbon traps in this relatively poorly-explored area. (Author)

  17. Extensional hard linkages, eastern Gulf of Suez, Egypt

    1998-06-01

    The Araba Abu Durba area on the eastern margin of the Gulf of Suez exhibits two superb outcrop examples of extensional hard linkages in a rift basin. Here, three large, domino-style, basement-cored, northeast-dipping fault blocks are formed by a series of major northwest-trending normal faults. These are offset by two north-northeast trending sinistral oblique-slip transfer faults that terminate in horsetail normal fault splays. The transfer faults do not extend across the entire rift basin. Detailed mapping and structural analysis show that they developed by breakage of initial low-strain relay ramps along reactivated north-northeast trending basement fabrics between overlapping northwest-trending normal fault segments. Paleostrain analysis of fault-slip indicators shows that both the normal and the sinistral oblique-slip transfer faults were formed synchronously in response to northeast-southwest extension, perpendicular to the main northwest rift trend.

    The Suez Rift is a 300 km long and 50 to 80 km wide basin which cuts a granitic and metamorphic shield of Precambrian age, covered by sediments of Paleozoic to Paleogene age. The rift structure is dominated by tilted blocks bounded by NW-SE normal faults. The reconstruction of the paleostresses indicates a N 050 extension during the whole stage of rifting. Rifting began 24 My ago with dikes intrusions; main faulting and subsidence occurred during Early Miocene producing a 80 km wide basin (Clysmic Gulf). During Pliocene and Quaternary times, faulting is still active but subsidence is restricted to a narrower area (Present Gulf). On the Eastern margin of the gulf, two sets of fault trends are predominant: (1) N 140 to 150 E faults parallel to the gulf trend with pure dip-slip displacement; and (2) cross faults, oriented NOO to N 30 E that have a strike-slip component consistent with the N 050 E distensive stress regime. The mean dip cross fault is steeper (70 to 80 deg) than the dip of the faults parallel to the Gulf (30 to 70 deg). These two sets of fault define diamond shaped tilted block. The difference of mechanical behavior between the basement rocks and the overlying sedimentary cover caused structural disharmony and distinct fault geometries.

    The subsurface structural evolution, facies changes and sequence stratigraphic interpretations of the Miocene successions of the southwestern part of the Gulf of Suez, Egypt, were studied by seismic reflection data of Twenty seven 3D seismic sections supported by the composite, velocity and vertical seismic profiles (VSP) logs of eight wells. Among them five sections and two geoseismic cross sections were selected to reveal the structural framework and depositional history of the study area. The analysis of depth-structure contour maps revealed that the Miocene strata are dissected by two major faults trends: The NW-SE trending faults (Clysmic trend) and the NE-SW trending cross faults running nearly perpendicular to the Clysmic faults. The facies changes of the syn-depositional Miocene units are controlled by the structural framework of the southern part of the Gulf of Suez being evolving diapiric structure of South Gharib Formation. The Miocene units are subdivided into two major 3rd order depositional sequences: S1 and S2.

    When the Norwegian corvette Nordstjernen was in the North Sea bound for Port Said to be present at the opening of the Suez Canal on 17 November 1869, an officer suffered a rupture of m. triceps brachii when he was drawn into the machinery during a storm. He was put ashore in Harwich; four days after the injury he was hospitalized in Colchester. The voyage was eventful in other ways too. Another officer died from typhoid fever in Ismailia. On the Swedish frigate Vanadis, also present at the opening of the Suez Canal, one of the doctors died from lung infection and was buried in Smyrna; a twelve-feet high column of white marble was taken from the ruins of Aesculap's temple and put on his grave. Denmark was represented by the frigate Sjaelland. During a storm in the North Sea, one seaman fell down on the deck from the foresail yard and suffered contusions and a fracture of the left clavicle. These cases illustrate challenges that faced our ancestors. The accident happened when the ship was in the Netherlands sector of the North Sea as we know it today. Today the Coast Guard could have arranged transport by helicopter and hospitalized the patient in about two hours. PMID:12555606

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

    Miocene sediments of the Gulf of Suez were deposited in a rapidly subsiding rift which became active during Late Oligocene and Early Pliocene tectonic episodes. Complex lithological variations associated with the variable submarine structure commonly preclude detailed correlation of drilled subsurface successions. Thick Middle to Late Miocene evaporites and their geometry obscure seismic interpretation of prospective sub-evaporitic Early and Middle Miocene sequences. The thick Miocene sediments are believed to have significantly furnished the source, as well as the reservoirs and seals for the oil discovered in the Gulf of Suez. Over four billion barrels of oil have been established as recoverable reserves in Miocene reservoirs. A new Gulf-wide detailed correlation scheme is established based upon a series of newly defined microfaunal assemblage zones. These zones are based on holistic analysis of microfauna utilizing planktonic and benthonic foraminifera, diatoms, otoliths and pteropods. Dating by planktonic foraminifera and calcareous nannofossils indicates the zones are isochronous. Vertical and lateral variations in assemblage characteristics have been identified, mapped and are concluded to be the results of vertical and lateral differences in salinity, water depth, water clarity, lithological variation and oxygen availability. The correlative applicability of this scheme within the Gulf of Suez provides potential for it to serve as a reference for drilled sequences in the Red Sea, where thicker evaporite sequences make sub-evaporitic stratigraphic correlation even more difficult owing to the greater seismic attenuation.

The study area harbored a diversified phytoplankton community (138 species), belonging to 67 genera. Four algal groups were represented and classified as Bacillariophyceae (90 species), Dinophyceae (28 species), Cyanophyceae (16 species), and Chlorophyceae (4 species). The results indicated a relative high occurrence of some species namely.; Pleurotaenium trabecula of green algae; Chaetoceros lorenzianus, Proboscia alata var. gracillima, Pseudosolenia calcar-avis, and Pseudo-nitzschia pungens of diatoms; Trichodesmium erythraeum and Pseudoanabaena limnetica of cyanophytes. Most of other algal species were fairly distributed at the selected stations of the study area. The total abundance of phytoplankton was relatively low (average of 2989 unit/L) in the eastern coast of Suez Gulf, as compared its western coast and the northern part of the Red Sea. The diversity of phytoplankton species was relatively high (2.35-3.82 nats) with an annual average of 3.22 nats in the present study. The results concluded that most of eastern coast of Suez Gulf is still healthy, relatively unpolluted, and oligotrophic area, which is clearly achieved by the low values of dissolved phosphate (0.025-0.3 μM), nitrate (0.18-1.26 μM), and dissolved ammonium (0.81-5.36 μM). Even if the occurrence of potentially harmful algae species was low, the study area should be monitored continuously. The dissolved oxygen ranged between 1.77 and 8.41 mg/L and pH values between 7.6 and 8.41. The multiple regression analysis showed that the dissolved nitrate and pH values were the most effective factors that controlled the seasonal fluctuations of phytoplankton along the eastern coast of Suez Gulf during 2012-2013.

    Detailed field mapping reveals that continental rifting is strongly deforming the Gebel Qattamiya-Gebel Um Reheiat area and the entire Cairo-Suez district, in north Eastern Desert of Egypt. Rift-related structures are predominantly represented by E to WNW, NNW and NW oriented faults. The E to WNW oriented faults are small and build up the Gebel Qattamiya en echelon fault belt, whereas the faults trending NNW and NW establish a pervasive horst and graben structural style involving some rhomb-shape horsts as Gebel Qattamiya (GQRH), Gebel Um Reheiat (GURRH) and south Gebel Um Reheiat (SGURRH). Rock units of the Eocene succession and Oligocene sediments are well exposed and highly controlled by rift-related structures. Rifting was developed through two rift-phases; initial and major ones. The initial phase (a newly recognized phase in this contribution) has been occurred in Late Eocene (Priabonian), while the main phase was prevailing during Late Oligocene-Early Miocene time and is characterized by hydrothermal veins and basaltic eruptions. Continental transtension in the Cairo-Suez district, including the study area, was probably synchronous with a major tectonic stage (Pyrenean-Atlasic movement) of continental collision between African-Arabian and Eurasian plates in Late Eocene-Oligocene time. Field investigation suggests that the transfer of displacement (slip) from the Gulf of Suez proto-rift into the E-W oriented faults ''relays'' is an important mechanism, which helps to explain the current structural framework and tectonic evolution of the Cairo-Suez district. Reactivation of such faults with right-lateral divergent wrenching with NE-SW oriented extension deformed the Cairo-Suez district with several E-W oriented en echelon fault belts (e.g. Gebel Qattamiya fault belt in the study area). Thus the Cairo-Suez district represents an accommodation or transfer zone in northeastern Egypt, intercepting the ''far-field stresses'' from the Arabian-Nubian Shield, the Red

    We present a detailed study about the initiation and reactivations of Zeit-El Tor transfer zone, south Gulf of Suez rift, and its structural setting and tectonic evolution with respect to the Cretaceous-Cenozoic tectonic movements in North Egyptian margin. NE trending zone of opposed-dipping faults (22 km wide) has transferred the NE and SW rotations of the sub-basins in central and south Gulf of Suez rift, respectively. The evolution of this zone started by reactivation of the NE oriented late Neoproterozoic fractures that controlled the occurrence of Dokhan Volcanics in the rift shoulders. Later, the Syrian Arc contraction reactivated these fractures by a sinistral transpression during the Late Cretaceous-Eocene time. N64°E extension of the Oligo-Miocene rift reactivated the NE fractures by a sinistral transtension. During this rifting, the NE trending faults forming the transfer zone were more active than the rift-bounding faults; the Upper Cretaceous reverse faults in the blocks lying between these NE trending faults were rotated; and drape-related reverse faults and the positive flower structures were formed. Tectonic inversion from contraction to extension controlled the distribution and thickness of the Upper Cretaceous-Miocene rocks.

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

    The Middle Miocene Kareem sandstones are important oil reservoirs in the southwestern part of the Gulf of Suez basin, Egypt. However, their diagenesis and provenance and their impact on reservoir quality, are virtually unknown. Samples from the Zeit Bay Oil Field, and the East Zeit Oil Field represent the Lower Kareem (Rahmi Member) and the Upper Kareem (Shagar Member), were studied using a combination of petrographic, mineralogical and geochemical techniques. The Lower Rahmi sandstones have an average framework composition of Q95F3.4R1.6, and 90% of the quartz grains are monocrystalline. By contrast, the Upper Shagar sandstones are only slightly less quartzose with an average framework composition of Q76F21R3 and 82% of the quartz grains are monocrystalline. The Kareem sandstones are mostly quartzarenite with subordinate subarkose and arkose. Petrographical and geochemical data of sandstones indicate that they were derived from granitic and metamorphic terrains as the main source rock with a subordinate quartzose recycled sedimentary rocks and deposited in a passive continental margin of a syn rift basin. The sandstones of the Kareem Formation show upward decrease in maturity. Petrographic study revealed that dolomite is the dominant cement and generally occurs as fine to medium rhombs pore occluding phase and locally as a grain replacive phase. Authigenic quartz occurs as small euhedral crystals, locally as large pyramidal crystals in the primary pores. Authigenic anhydrites typically occur as poikilotopic rhombs or elongate laths infilling pores but also as vein filling cement. The kaolinite is a by-product of feldspar leaching in the presence of acidic fluid produced during the maturation of organic matter in the adjacent Miocene rocks. Diagenetic features include compaction; dolomite, silica and anhydrite cementation with minor iron-oxide, illite, kaolinite and pyrite cements; dissolution of feldspars, rock fragments. Silica dissolution, grain replacement and

    The Lower Miocene Rudies sandstones are important oil reservoirs in the southeastern part, Gulf of Suez basin, Egypt. However, their provenance and diagenesis and their impact in reservoir quality, are virtually unknown. Samples from the Warda field, representing the Lower and Middle Rudies, were studied using a combination of petrographic, mineralogical and geochemical techniques. The Lower Rudies sandstones have an average framework composition of Q85F7.2R7.8, and 83% of the quartz grains are monocrystalline. By contrast, the Middle Rudies sandstones are only slightly more quartzose with an average framework composition of Q90F7R3 and 86% of the quartz grains are monocrystalline. Rudies sandstones are mostly quartz arenite with subordinate subarkose and sublithic arenites and their bulk-rock geochemistry support the petrographic results. The modal analysis data of studied samples suggest influence of granitic and metamorphic terrains as the main source rock with a subordinate quartzose recycled sedimentary rocks. The geochemical data interpretation on the basis of discriminate function diagrams reveal the source material was deposited on a passive margin. Textural attributes possibly suggest long-distance transport of grains from the source region and indicates a cratonic or a recycled source. Tectonic setting of Rudies Formation reveals that the lower Rudies sandstones are typically rift sandstone and their deposition constrained the beginning of the faulting, while the middle Rudies sandstones were transported from the far along the rift. Diagenetic features include compaction; dolomite, silica and anhydrite cementation with minor iron-oxide, illite, kaolinite and pyrite cements; dissolution of feldspars, rock fragments. Silica dissolution, grain replacement and carbonate dissolution greatly enhance the petrophysical properties of many sandstone samples.

    The Caprellidae from the Red Sea are reviewed based on the literature data and new collections from the Hurghada coasts. So far, only six valid species has been reported from the Red Sea and Suez Canal: Caprella equilibra Say, 1818, Hemiaegina minuta Mayer, 1890, Metaprotella africana Mayer, 1903, Paracaprella pusilla Mayer, 1890 and Paradeutella multispinosa Schellenberg, 1928 and Pseudocaprellina pambanensis Sundara Raj, 1927. The type material of M. africana (deposited in the Muséum nacional d'Histoire naturelle, Paris) and Paradeutella multispinosa (deposited in the Museum für Naturkunde, Berlin) are redescribed and illustrated in detail. P. pambanensis and H. minuta were the most abundant species in the collections along the northern coast. Most of the sampling effort has been focused on algae from shallow waters; additional substrates such as sediments, hydroids and coral rubble, especially from areas deeper than 15 meters should be explored. The number of caprellid species in the Red Sea is low compared to adjacent waters, as the Mediterranean Sea. However, further research and more extensive caprellid collections should be conducted along the coasts of Saudi Arabia, Yemen, Sudan and Eritrea, which are still unexplored. PMID:27394584

    Full Text Available Background: Diabetic neuropathy (DN can affect any part of the nervous system and should be suspected in all patients who have had diabetes for more than 5 years. Family physicians (FPs can play an important role with the care and education of people with diabetes. They can augment the knowledge and motivate the diabetics to acquire a healthy life style, which would further lead to a good glycemic control providing protection from the chronic complications. Lack of compliance with the guidelines on the part of the diabetic subjects, indicates deficiencies in the FPs' knowledge, implementation techniques, and attitude problems. Therefore, the present study was conducted to assess FPs' knowledge, attitude, and practice regarding DN for further educational interventions that will improve their quality of care for diabetic patients in family practice centers. Materials and Methods: The study population was 60 FPs working in family practice centers affiliated to Suez Canal University Hospitals. The questionnaire composed of three groups of questions to collect data for evaluation of knowledge, attitude, and practice; two written patient problems to assess their practice and two questions to assess barriers and recommendations of physicians. To pass the evaluation; 50, 80, and 60% were the cut off points to pass the evaluation for knowledge, attitude, and practice, respectively. Results: 48.3, 66.7, and 43.3% of the evaluated FPs passed the knowledge, attitude, and practice assessment, respectively. Eighty-five percent of physicians felt that they need more knowledge and training in DN management. Physicians' qualification (P = 0.037 was a significant variable in passing the knowledge test, but qualification and experience years (P = 0.007 and 0.035, respectively were significant variables in passing the practice test. There was a positive significant (P = 0.021 correlation between practice and knowledge score. Postgraduate knowledge accounts the

    The Maastrichtian-Lower Eocene sediments on both sides of the northern Gulf of Suez can be subdivided into eight formal formations (including one group) and one informal formation that are described in detail. These lithostratigraphic units reflect three different environmental regimes of deposition or non-deposition. The first regime is characterised by uplift and erosion or non-deposition resulting mostly from the uplift of the Northern Galala/Wadi Araba structure, a branch of the Syrian Arc Foldbelt. The shallow water carbonate platform and slope deposits of the Late Campanian-Maastrichtian St Anthony Formation and the Paleocene-Lower Eocene Southern Galala and Garra Formations represent the second regime and are found north and south of the Northern Galala/Wadi Araba High. The third regime is represented by basinal chalks, marls and shales of the Maastrichtian Sudr Formation and of the Paleocene-Eocene Dakhla, Tarawan and Esna Formations, the Dakhla/Tarawan/Esna informal formation and the Thebes Group. The distribution and lateral interfingering of the above mentioned environmental regimes reflect different vertical movements, changing basin morphology, sea level changes and progradation of shallow water sediments and is illustrated on 11 palæogeographic maps.

    2014-05-01

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

  17. Analysis of the similar epicenter earthquakes on 22 January 2013 and 01 June 2013, Central Gulf of Suez, Egypt

    2016-09-01

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

  18. Excavation of a Qattara Canal in Egypt: two-dimensional nuclear cratering calculations

    International Nuclear Information System (INIS)

    A series of single-charge nuclear cratering calculations were performed. Results from these calculations are being used in a study of the technical feasibility of the Qattara Project. The project would use nuclear explosives with yields ranging between about 200 and 1750 kilotons to excavate a canal about 73 km long connecting the Mediterranean Sea with the below sea-level Qattara Depression in northwestern Egypt. Computer simulations of explosive excavations were carried out at four locations near the proposed Qattara alignment. Holes were drilled in Egypt at these locations to depths of 372, 514, 632, and 701 m, respectively, to provide geophysical information needed to properly characterize each site for computer calculations. The calculated results for ground motion, particle velocity, and crater dimensions for these nuclear excavations are presented

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

    The inorganic chemical water quality of the Ismailia Canal / Egypt was studies in 2003 and 2004 at seventeen different sites from the main canal between Cairo and Ismailia. Additional samples were taken from selected discharges and groundwater sources. As the Ismailia Canal is fed by water from the Nile some samples were taken from the Nile near Aswan for comparative reasons too. Water samples were analysed for sum parameters, salts, heavy metals and natural radioactivity. Especially in the Greater Cairo Area due to different uncontrolled discharges pH and conductivity changed significantly when proceeding from up to downstream sites. The water temperature increased significantly during the first 20 km. The main reason was the discharge of warm water used to cool machinery in the industrial suburb of Cairo. Iron, Zinc and Manganese were found in low concentrations. Because of dilution effects the amounts of dissolved salts were still below the German ''Trinkwasserverordnung''. A higher total organic carbon level indicated the presence of organic contaminants however. The natural radioactivity level was in the normal range. (orig.)

    Full Text Available The Mahmoudia Canal is the main source of municipal and industrial water supply for Alexandria (the second largest city in Egypt and many other towns and villages. In recent years, considerable water quality degradation has been observed in the Mahmoudia Canal. This problem has attracted increasing attention from both the public and the Egyptian government. As a result, this study aims at assessing the current seasonal variations in water quality in the Mahmoudia Canal and simulating various water quality management scenarios for the canal. The present research involves the application of the water quality model, QUAL2K, to predict water quality along the Mahmoudia Canal on a seasonal basis for the considered scenarios. Based on the QUAL2K simulations, the River Pollution Index (RPI was used to appraise the conditions of water pollution at the intakes of the twelve water treatment plants (WTPs located along Mahmoudia Canal. The results showed that the QUAL2K model is successfully applied to simulate the water quantity and quality parameters of the Mahmoudia Canal in different seasons. For the current status of the canal, it was found that the highest pollution level occurred in autumn in which effluent water quality at all WTPs along the Mahmoudia Canal was classified as moderately polluted. In the other seasons, effluent water quality was categorized as moderately polluted at most WTPs in the Beheira governorate and negligibly polluted at all WTPs in the Alexandria governorate. Moreover, it was concluded that controlling the Rahawy drain discharge or treating its pollution loads before mixing with the Rosetta Branch may solve water quality problems of the Mahmoudia Canal and allow re-running of the Edko re-use pump station in summer, winter, and spring. However in autumn, additional measures will be required to mitigate pollution levels in the canal.

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

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

    Full Text Available Aluminum is released into Sabal drainage canal through the emissions of recycled aluminum industries, the discharge of stations of water purification that contain huge amount of aluminum sulfate (alum and the extensive use of clay in the industry of packed bricks. The aim of this study was to investigate the impact of human activities on Al accumulation on water and fish consumption. The field and laboratory studies of water samples and different fish tissues (muscles, liver and ovary revealed that water samples had higher levels of Aluminum if compared to those collected from other localities. Tissue samples of the fish, Tilapia zillii had higher levels of Al which exceeded the international permissible limits. From a public health standpoint, the increased concentrations of Al in water samples and the fish tissues in the are is a matter of concern. Therefore, the research suggests the elimination of illegal aluminum industries and replace the smaller and old stations of sewage treatment by another modern type capable of collecting and treating huge amount of sewage, with high efficiency of treatment and purification.

    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.

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

    Full Text Available INTRODUCTION: Occult hepatitis B infection (OBI is considered to be one of the major risks for patients suffering from end-stage renal disease (ESRD on regular hemodialysis (HD and patients with chronic hepatitis C virus (HCV infection. This study compared the prevalence of OBI among these two high-risk groups in the Suez Canal region, Northeastern Egypt, to obtain a better national overview of the magnitude of OBI in this region. METHODS: Serum samples were collected from 165 HD patients and 210 chronic HCV-infected patients. Anti-HCV antibody, hepatitis B surface antigen (HBsAg, total hepatitis B core (anti-HBc antibody, and hepatitis B surface antibody (anti-HBs were detected by enzyme-linked immunosorbent assay (ELISA. HCV RNA was detected using a quantitative real-time RT-PCR assay, and HBV was detected using a nested PCR. RESULTS: All patients were negative for HBsAg. A total of 49.1% and 25.2% of the patients in the HD and HCV groups, respectively, were anti-HBc-positive. In addition, more anti-HBs-positive patients were detected in the HD group compared to the HCV group (52.1% and 11.4%, respectively. Three cases were positive for HBV DNA in the HD group, while eighteen positive cases were detected in the HCV group. Both study groups showed significant differences in serum alanine aminotransferase (ALT and aspartate aminotransferase (AST level as well as anti-HBc, anti-HBs and HBV-DNA positivity. CONCLUSIONS: OBI was more prevalent among chronic HCV patients than HD patients in the Suez Canal region, Egypt, with rates of 8.5% and 1.8%, respectively. However, more precise assessment of this infection requires regular patient follow-up using HBV DNA detection methods.

    The reclamation policy to alleviate overpopulation problem of the Nile Delta, Egypt, has created both quality and quantity problems for the Quaternary aquifer beneath the reclaimed areas. It is partly because of the less well managed way for land use planning and lack of the environmental impact assessment at least at the early stage of the development. A stable isotopic ( δ 18O and δ 2H) and hydrochemical investigation was carried out in the reclaimed area at the south of the Ismailia Canal to identify recharge sources, and mixing and salinization processes of the Quaternary aquifer. On the basis of the isotopic data, four end-members, i.e., the Quaternary aquifer, the Miocene aquifer, surface freshwater and wastewater ponds were found to be mixed in different degree in the study area. As a consequence of mixing with groundwater in the Miocene aquifer which shows highly saline and depleted isotopic signature, groundwater in the Quaternary aquifer was found to have a depleted isotopic trend towards south, i.e., toward structural highs. On the contrary, northward trends of the enriched isotopic values and lower EC values in the Quaternary aquifer indicated the mixing with surface water. Local abnormal EC values at an agricultural area and the vicinity of well field were considered to be related to the excessive pumping for irrigation and reclamation activities which in turn resulted in upconing of deeper saline groundwater. Mixing pattern also suggested local contribution of the wastewater ponds to the recharge process, which is consistent with the previously reported heavy metal contamination in the vicinity of these ponds, indicating the necessity to protect and remediate the subsurface water resources in the area.

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

    Full Text Available The research was conducted at the Agriculture Research Farm, Faculty of Agriculture, University of Suez Canal during the sesame growing seasons of 2011 and 2012. For the purpose of studying the impact of insect pollination and nitrogen fertilization on sesame production, the experiment was divided into 13 treatments of open pollination and non open pollination with three different levels of ammonium nitrate (N and one level of seryalin as bio-fertilizer. Non open pollination treatments were covered before the start of flowering period with a perforated net bag to allow the air to pass through and to prevent insects from approaching the plants. Quantitative and qualitative parameters were measured as follows: number of capsules per plant, capsule weight, number of seeds per capsule, weight of 1000 seeds, germination rate, seedling vigour and oil content. Results clearly demonstrate that qualitative and quantitative parameters of sesame crop significantly increased with open pollination and with the increase of nitrogen fertilizer level up to 95 kg N/ha plus or minus seryalin in reclaimed sandy soils in Ismailia, Egypt.

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

  9. Provenance of Gebel El-Zeit sandstones, gulf of Suez, Egypt

    Abdel-Wahab, Antar A.

    1992-01-01

    The Paleozoic elastic succession at Gebel Zeit chiefly consists of fine- to medium-grained quartz arenite, locally containing well-rounded quartz pebbles. The marine Araba Formation (Early Cambrian) was deposited during transgression over a Precambrian granite. The overlying Naqus Formation (Late Cambrian) is fluvial, except for the uppermost few meters. Paleocurrent data for the Araba and Naqus formations indicate derivation from the north-northeast and south-southwest respectively. Quartz typology, other morphologic features of quartz, and mineral inclusions in quartz, as well as the study of heavy minerals were used to determine the provenance of the sandstones. Quartz typology successfully identified a granitic source for the Araba Formation. A combination of parameters indicates that the Naqus Formation was derived chiefly from a metamorphic terrain. Two ratios, polycrystalline/monocrystalline quartz and undulose/non-undulose quartz, successfully distinguish sandstones of the Araba Formation from those of the Naqus Formation. These values are 0.14 and 0.25 for Araba sandstones and 0.26 and 0.46 for Naqus sandstones, respectively. These differences either reflect different source rocks, or have resulted from selective abrasion loss of polycrystalline quartz in the rigorous surf zone during the marine transgression that deposited the Araba Formation.

    1990-05-01

    At the northern corner of El Zeit Range, 370 m of sandstone overlie Precambrian granite and underlie Cretaceous marine strata. The sandstones include the marine Lower Cambrian Araba Formation and the overlying dominantly fluvial Upper Cambrian( ) Naqus Formation The framework composition of both sandstones is almost entirely quartz with trace amounts of muscovite, K-feldspar, and heavy minerals. Up to 18% oversize pores, some filled with younger cements, attest to extensive dissolution loss of detrital grains. Because the final mineralogical maturation of these quartzarenites was through diagenesis, they are diagenetic quartzarenite. During burial diagenesis, the introduction of 5% quartz cement (unhomogeneously distributed) was followed by locally pore-occluding calcite cement. The sands were then compacted sufficiently to develop slightly sutured quartz grain contacts. These events were followed by extensive dissolution loss of carbonate cement, detrital feldspars, micas, and heavy minerals; by the formation of local patches of kaolinite (average = 6%); and by the formation of extensive iron-oxide cement, including specular hematite. These features suggest extensive invasion of meteoric water and exposure to oxidizing conditions. The time of this event can only be dated as post-Cambrian( ) and pre-Cenomanian. Some outcrop samples contain pore-occluding gypsum cement or mixtures of gypsum and halite cement. Sr{sup 87}/Sr{sup 86} ratios of four samples of gypsum cement have two modes equal to 0.7079 and 0.7085. These values are those of Miocene and slightly younger seawater. They suggest that evaporites were leached by modern meteoric water from nearby exposed Miocene and younger marine evaporite-bearing strata, transported in surface and groundwater to the topographically low terrain where the Cambrian sandstones crop out, and were precipitated by evaporation of surface water.

    In the northern corner of the El Zeit range, 370 m of sandstone overlie Precambrian granite and underlie Cretaceous marine strata. The sandstones include the marine Lower Cambrian(?) Araba Formation and the overlying, dominantly fluvial, Upper Cambrian(?) Naqus Formation. The framework compositions of both sandstones are almost entirely quartz, with trace amounts of muscovite, K-feldspar and heavy minerals. Up to 21% oversize pores, some filled with younger cements, attest to extensive dissolution loss of detrital grains. Because the final mineralogical maturation of these quartzarenites reflects diagenesis, they are diagenetic quartzarenites. During burial diagenesis, the introduction of up to 8% quartz cement (inhomogeneously distributed, mean = 3%) was followed by local, pore-occluding calcite cement, which halted compaction. Sandstones without calcite cement underwent additional mechanical and chemical compaction sufficient to develop sutured quartz grain contacts and reduce porosity (˜27%). These events were followed by: (1) extensive dissolution loss of carbonate cement, detrital feldspars, micas, and heavy minerals; (2) formation of local patches of kaolinite (mean = 3%); and (3) formation of extensive iron-oxide cements, including specular hematite. These features suggest extensive invasion by oxidizing meteoric water. The timing of this event can only be dated as post-Cambrian(?) and pre-Cenomanian. Some outcrop samples contain pore-occluding gypsum cement, or mixtures of gypsum and halite. Sr 87/Sr 86 ratios of four samples of gypsum cement have values (0.7079 and 0.7085) that indicate Miocene and slightly younger seawater. Evaporites were evidently leached by modern meteoric water from nearby outcrops of Miocene and younger marine evaporite-bearing strata, transported in surface and ground water to the topographically low terrain where the Cambrian sandstones crop out, and reprecipitated by evaporation. Initial primary porosity (45%) was reduced to ˜27% by compaction in sands with minor quartz cement; compaction ceased where calcite was precipitated. Subsequent dissolution of some calcite cement and unstable detrital grains generated considerable secondary porosity.

    Presence of sandstone streaks in Sidri Member within Belayim Formation that lies between two productive zones; Kareem Formation and Hammam Faraun Member, was the main reason to perform this study. It may represent a good hydrocarbon reservoir and will be added to the Egyptian oil production in some wells of Badri field. This Member has high resistivity signature on Electric-logs responses which attracted the attention to investigate its occurrence in the field, to delineate its distribution all-over the area, to evaluate the petrographic and petrophysical characteristics and to evaluate its productivity. Petrographic and petrophysical analyses of these sand zones were undertaken using thin section samples. The electric logs and subsurface geologic data was used to evaluate the main reservoir characteristics of the Sidri sandstone such as lithology, cementation, shale volume, porosity (Φ), effective porosity (Φ eff), estimated permeability (K), fluid saturation, fluid type and Net pay thickness. This study revealed that, Sidri sandstone facies was classified into two mainly sandy facies; blocky sandy facies which located at the northern part of the field and streaky sandy facies at the southern area of the field. These two facies are separated by shaley facies. Some wells were studied to represent the two sandy facies in Sidri Member and these sand intervals have not been tested yet. These sands consist of quartz grains with grey and pink feldspars as accessory minerals, with siliceous and calcareous cementation, with good porosity. Petrophysical evaluation of this sand unit indicated that it is hydrocarbon bearing formation in three wells and water bearing one in other wells. Electrical logs analysis (Resistivity, Density-Neutron, Sonic and Gamma-Ray) revealed that The volume of shale in this sandstone, the effective porosity, the water saturation, the estimated permeability, the hydrocarbon saturation, and the net-pay thickness are varying from 9 to 13%, 19%-22%, 26%-34%, 200 and 600 mD, 66 and 74%, 20-35 feet respectively. The fluid types are oil, gas and water.

    Swamy, Ashwin Balegar

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

    Full Text Available The Panama Canal, together with the Suez Canal, is an engineering accomplishment which is now regarded as a master work marking the initiation of modern civil engineering. Other projects, also of great magnitude, do not seem to maintain the reputation of the above two, because they cannot continue to serve their function with sustained usefulness in the new circumstances of today. The Panama Canal, with its limited dock capacity, and the narrow, so called Serpent, canal, has had to cope with a continuously increasing volume of shipping traffic; a natural consequence of commercial evolution. In order to keep up with these increasing demands, it has been necessary to carry out an almost uninterrupted series of modifications and improvements, affecting both the method of operation and organisation, and the actual nature of the canal. Thanks to these alterations the Panama Canal has continued to maintain, at least nominally, an adequate standard of functional efficiency. At present the canal is being widened over certain sections to enable the easy passage of ships of great displacement. The work is being done very rapidly, and in order to gain time, it has been distributed to various contractors simultaneously.El canal a través del ismo de Panamá es una obra de ingeniería civil que, junto con el de Suez, empiezan ya a clasificarse como obras maestras que señalan el primer jalón del desarrollo de la ingeniería moderna.

    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.

    At the request of GDF Suez, a Rough Order of Magnitude (ROM) cost estimate was prepared for the design, construction, testing, and data analysis for an experimental series of large-scale (Liquefied Natural Gas) LNG spills on land and water that would result in the largest pool fires and vapor dispersion events ever conducted. Due to the expected cost of this large, multi-year program, the authors utilized Sandia's structured cost estimating methodology. This methodology insures that the efforts identified can be performed for the cost proposed at a plus or minus 30 percent confidence. The scale of the LNG spill, fire, and vapor dispersion tests proposed by GDF could produce hazard distances and testing safety issues that need to be fully explored. Based on our evaluations, Sandia can utilize much of our existing fire testing infrastructure for the large fire tests and some small dispersion tests (with some modifications) in Albuquerque, but we propose to develop a new dispersion testing site at our remote test area in Nevada because of the large hazard distances. While this might impact some testing logistics, the safety aspects warrant this approach. In addition, we have included a proposal to study cryogenic liquid spills on water and subsequent vaporization in the presence of waves. Sandia is working with DOE on applications that provide infrastructure pertinent to wave production. We present an approach to conduct repeatable wave/spill interaction testing that could utilize such infrastructure.

  6. Radiological Review Studies On Ismailia Canal Ecology

    International Nuclear Information System (INIS)

    The present work is a brief review of pr-studies carried out on Ismailia Canal, Egypt, water ecosystem. Ismailia Canal water body is a bicarbonate stream with slight seasonal variations in its water chemical constituents. The canal water pH in all the stream locations are below 8.3 with low suspended matter(SM) content (22-33 mg.l-1). The mineralogical analysis of the canal bottom sediments consist mainly of quartz, smectite and kaolinite minerals. The γ- spectroscopic identification showed traces of naturally occurring radio nuclides (238U, 232Th and 40K). The average activity level of the dry samples ranged from 12 to 89 Bq.Kg-1 for the detected natural radio nuclides. Some parameters affected the sorption behaviour of radio nuclides on suspended matters and bottom sediments; such as solution pH, SM concentration, sediment grain size, carrier concentration and competing ions were studied. The reaction rates were investigated for each radionuclide studied. The distribution of the studied radio nuclides, between the liquid phase and the sediments phase was investigated, for both flowing and static systems. For both flowing and non-flowing (static), the depth penetration of the studied radio nuclides within the bottom sediment layers were found to vary from one radionuclide to the other. The total capacities of bottom sediments and the suspended matter were found to be low. As Ismailia Canal is an important source of water for public domestic uses, irrigation animals and the aquatic species; these situations have led to state that it is not recommended to release any liquid radioactive wastes to this canal. Furthermore, periodical radiometric analysis for the canal water and its components should be carried out.

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

    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.

    Science.gov (United States)

    Abdel-Wahab, Antar; Allam, A.; Kholief, M.; Salem, A.

    1992-01-01

    The present work deals with the sedimentological and palaeoenvironmental studies of the Palaeozoic clastic sequence (Cambrian?) of the Gebel El-Zeit area. The sandstones which build up the major part of this sequence are fine to coarse grained moderately to well sorted, mostly of unimodal patterns, strongly fine skewed to near symmetrical and vary from meso- to very lepto-kurtic. The grain-size parameters and their bivariate relations do not give an exact environment of deposition nevertheless, most of them have a fluviatile origin. So, the application of some of the bivariate relations to ancient sediments, which microscopically show mild or no cementation, is still valid if coupled with other parameters, such as sedimentary structures, palaeocurrent analysis and other confirmed data. The palaeocurrent analysis indicates that these sandstones came from two completely different sources. A marine transgression from the north northeast produced the Araba Formation, whereas the Naqus Formation has been interpreted as fluvial. The source is situated to the south southwest. The streams were probably very erratic and intermittent.

    The reservoir parameters (total gross thickness, shale volume, total porosity, effective porosity, water saturation, bulk pore volume, net pay thickness and oil in place indicator) of Kareem and Belayim formations are studied through nine wells and mapped to show the aerial distribution of these parameters. Interpretation of these maps showed that, the best locations of hydrocarbon accumulation in Belayim marine oil field are middle part, northeast and the south west directions for Kareem formation and southwest and northeast directions for Belayim formation. The petrophysical results of Belayim formation were presented in the form of 3D slicing models to exhibit the variation of these parameters in the different directions. Cross plots of Kareem formation were done using neutron, density and sonic logs which is directly influenced by the matrix composition. By using two or three porosity logs reading we determined the porosity and evaluated the matrix characteristics of Kareem formation as it is considered as a good reservoir for oil and gas and mainly composed of sand stone. Finally, facies maps for Kareem and Belayim formations which established using composite logs indicate that, the environment of deposition of Kareem formation was deep marine in the middle and northern parts and shallow in the southern parts of the study area, meanwhile in Belayim formation the environment of deposition was in lagoonal through the deposition of Baba and Feiran members and shallow to deep during the sedimentation of Sidri and Hammam Faraun members.

    2015-04-01

    Full Text Available Wheat (Triticum sativum L. is one of the most important cereal crops in Egypt. Insect pests, such as aphids, are major threats in terms of yield reduction. Induced resistance in wheat using salicylic acid as a foliar application was tested on the farm of the Faculty of Agriculture, Suez Canal University during 2012/2013 and 2013/2014 seasons. Three wheat cultivars, Gemeza 9, Sakha 93 and Giza 168, were sprayed three times with two concentrations of salicylic acid (SA, 200 mg/l and 100 mg/l, after early detection of aphid infestation by infrared thermal imaging. The infrared thermal imaging technique is based on significant differences in surface temperature between infested and healthy leaves. Imaging data are digital, and a computer program can be used to detect infestation rapidly. The results showed that aphid infestation raised the temperature of infested leaves, compared to healthy leaves. The range temperature difference between maximum and minimum temperatures (At was 1.1 ºC in healthy leaves and 3.9 ºC in infected leaves. The results of SA application showed significant differences in the mean number of aphids and in reduction of infestation among treatments and cultivars. The higher of the two SA rates (200 mg/l gave higher efficacy in the three cultivars than the lower rate (100 mg/l over the five weeks of trial. The highest efficacy against aphids was reached one week after application (86.28% for Giza, 85.89% for Gemesa and 70.54% for Sakha. Moreover, SA treatment enhanced the wheat yield of all three cultivars, compared with control plants. The three cultivars (Giza, Gemesa and Sakha produced higher yields than the control when sprayed with 200 mg/l SA. Their grain yield was 2,491.5, 2,455.0, and 2,327.25 kg/feddan (1 fed = 0.42 ha, respectively. In conclusion, infrared thermal imaging can be employed in identification of infected leaves. Also, the application of SA on wheat induced plant resistance to aphids.

    The authors first propose an analysis of European practices in terms of regulated tariffs. They outlines that these tariffs have disappeared in most of the historic member countries, but are still present in new coming countries but with different practices, and that tax-excluded prices for households in France are greater than the European average. They show that the tariff formula in the public service contract 2010-2013 between the State and GDF Suez does not take some supply cost optimization possibilities into account. They discuss the fact that the market context is still characterized by a separation between market prices on the one hand, and gas prices defined in long term contracts on the other hand. They show GDF Suez supply diversification allows a cost optimization

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

We are now starting to face the challenges of early detection of breast cancer as well as the implementation of proper modern management. Dorria S. Salem et al. publish in this issue of the Journal of Egyptian NCI an outline and initial results of a very ambitious Women Health Outreach Program (WHOP) designed to be completed in 5 phases 1. 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.

    1992-01-01

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

    This study was undertaken to analyze farmers' adaption to water scarcity in the command area of a secondary canal in the Nile Delta of Egypt. The results revealed that farmers' responses were driven by a multiplicity of factors, beyond water scarcity or profit maximization. These additional factors include food security of the family, risk management, social capital and history of farmers, and most unexpectedly the collective dimension of crop choice. The findings of this study expose the lim...

  9. Organ transplantation in Egypt.

    2010-09-01

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

  14. Cadmium status in Egypt

    Institute of Scientific and Technical Information of China (English)

    2001-01-01

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

  15. Egypt/FOF reorganize.

    Science.gov (United States)

    1984-01-01

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

    El Ayouti M. K.

    2006-10-01

    Full Text Available Accumulations of oil were first known in Egypt since 1968, some ten years after the famous Drake well in Pennsylvania in August 1859. These oil accumulation were found as seepages in tunnels dug for extracting sulphur in the area of Gemsa on the West coast of the Gulf of Suez. Since that time exploration activites were conducted on and off throughout a long history of operations which witnessed the use of the latest developments in exploration tools and techniques. So far, the main oil province in Egypt is the Gulf of Suez Basin, where the bulk of oil reserve have been found. Other hydrocarbon provinces are the Nile Delta Basin, the Abu Gharadig Basin and the Alamein ridge, both in the Western Desert. Three important gas discoveries were made in the Nile Delta Basin two of which are offshore, in addition to other so for non commercial gas finds. In addition to the known oil and gas discoveries the exploration activities throughout that long period contributed volumenous geological and geophysical material and data which added appreciably to the geology of Egypt at large, and in particular to the petroleum geology of the country. The Gulf of Suez oil province displayed very favourable conditions for the generation and trapping of hydrocarbons in Miocene and Pre-Miocene pools though at the same time it displayed very complicated geological setting which renders the exploration work a difficult task. The Nile Delta Basin, on the otherhand, is a relatively very recently explored area. Accordingly, extensive exploration work is still needed in order to evaluate the hydrocarbon possibilities of that basin. So for, gas has been discovered at a number of locations in lower Pliocene-Miocene pools. Whether future work would prove that oil generation took place remains to be seen. The Western Desert did not yet display the required response with regards to the exploration work conducted till now. To date, only few small discoveries have been made with oil

  3. Solar Energy for Rural Egypt

    Science.gov (United States)

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

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

  4. Ear canal cholesteatoma.

    Holt, J J

    1992-06-01

    Although cholesteatomas are more commonly found in the middle ear and the mastoid, the disease can occur in the external ear canal. All cases of ear canal cholesteatoma treated by the author were reviewed. There were nine ears in seven patients, who had an average age of 62 years. The lesions ranged in size from a few millimeters to extensive mastoid destruction. Smaller lesions can be managed by frequent cleaning as an office procedure. Larger lesions require surgery, either canaloplasty or mastoidectomy. The otolaryngologist should suspect this disease in the elderly. Microscopic examination of the ear with meticulous cleaning of all wax, especially in elderly patients, is most useful in detecting early disease. Frequent applications of mineral oil to the canal should be used in the management of the disease and to prevent recurrence. PMID:1376388

    Bell, Peter M.

    The Environmental Protection Agency (EPA) conducted a 3-month monitoring study of the Love Canal area near Niagara Falls, N.Y., after the federal government pronounced that a potential health risk existed due to chemical waste dumps. In 1982 the Department of Health and Human Services (HHS) decided that the area was habitable, subject to implementation of effective safeguards against leakage from the canal and to cleaning up of the contaminants. Now, the Congressional Office of Technology Assessment (OTA) has announced that, with the information available, it is not possible to demonstrate with certainty that unsafe levels do not exist within the so-called “emergency declaration area” (EDA).

  6. Present Situation of GPS Observations and Seismicity in and around Egypt

    2016-07-01

    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

    2015-01-01

    Bryozoan nodules, coralline algae, scleractinian corals and oysters form an important or-ganic buildup, 1.2–4.5 m thick in the Langhian-Serravaliann sediments of Egypt. Based on type, shape and size of the substrate, bryozoan nodules take tree-like and globular morphologies. Tree-like speci-mens reach 10 cm in maximum height and 3 cm in diameter, while Globular ones attain 9 cm in maxi-mum diameter. Most tree-like nodules are perforated with wide or narrow pores, few are non-perforated. Globulars and few tree-like forms are with mamelon-like structures. Perforations on the outer surfaces may indicate a symbiotic relationship between bryozoans and a live plant substrate. Nod-ules from Homiera and Gharra areas of the Cairo-Suez District with wider perforations may indicate growth in slightly lighter or turbid areas of the continental shelf than those of North Western Desert of narrower perforations. Non-perforated nodules may assume an incrustation on ephemeral substrate.

    Full Text Available The aim of this article is to provide an insight into different techniques of cleaning and shaping of curved root canals with hand instruments. Although a plethora of root canal instruments like ProFile, ProTaper, LightSpeed ® etc dominate the current scenario, the inexpensive conventional root canal hand files such as K-files and flexible files can be used to get optimum results when handled meticulously. Special emphasis has been put on the modifications in biomechanical canal preparation in a variety of curved canal cases. This article compiles a series of clinical cases of root canals with curvatures in the middle and apical third and with S-shaped curvatures that were successfully completed by employing only conventional root canal hand instruments.

  10. Remote sensing, planform, and facies analysis of the Plain of Tineh, Egypt for the remains of the defunct Pelusiac River

    2013-11-01

    The Pelusiac Branch was a distributary river in the Nile Delta that splits off from the main trunk of the Nile River as it flowed toward the Mediterranean. At approximately 25 A.D., it was chocked by sand and silt deposits from prograding beach accretion processes. The lower course of the river and its bifurcation point from the trunk of the Nile have been hypothesized based on ancient texts and maps, as well as previous research, but results have been inconsistent. Previous studies partly mapped the lower course of the Pelusiac River in the Plain of Tineh, east of the Suez Canal, but rapid urbanization related to the inauguration of the Peace Canal mega-irrigation project has covered any trace of the linear feature reported by these previous studies. The present study used multispectral remote sensing data of GeoEYE-1 and Landsat-TM to locate and accurately map the course of the defunct Pelusiac River within the Plain of Tineh. Remote sensing analysis identified a linear feature that is 135 m wide at its maximum and approximately 13 km long. It extends from the Pelusium ruins to the Suez Canal, just north of the Peace Canal. This remotely located linear feature corresponds to the path of the Pelusiac River during Roman times. Planform geomorphology was applied to determine the hydrological regime and paleodischarge of the river prior to becoming defunct. Planform analysis derived a bankfull paleodischarge value of ~ 5700 m3 s- 1 and an average discharge of 650 m3 s- 1, using the reach average for the interpreted Pelusiac River. The derived values show a river distributary similar in discharge to the modern dammed Damietta river. Field work completed in April of 2012 derived four sedimentary lithofacies of the upper formation on the plain that included pro-delta, delta-front and delta-plain depositional environments. Diatom and fossil mollusk samples were also identified that support coastal beach and lagoonal environments of deposition. Measured section columns

    2012-01-01

    Full Text Available Dilaceration is the result of a developmental anomaly in which there has been an abrupt change in the axial inclination between the crown and the root of a tooth. Dilaceration can be seen in both the permanent and deciduous dentitions, and is more commonly found in posterior teeth and in maxilla. Periapical radiographs are the most appropriate way to diagnose the presence of root dilacerations. The controlled regularly tapered preparation of the curved canals is the ultimate challenge in endodontics. Careful and meticulous technique will yield a safe and sufficient enlargement of the curved canals. This article gives a review of the literature and three interesting case reports of root dilacerations.

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    Objective To investigate the advantages of canal wall reconstruction (CWR) mastoidectomy, a single-stage technique for cholesteatoma removal and posterior external canal wall reconstruction, over the open and closed procedures in terms of cholesteatoma recurrence. Methods: Between June 2002 and December 2005, 38 patients (40 ears) with cholesteatoma were admited to Sun Yat-Sen Memorial Hospital and received surgical treatments. Of these patients, 25 were male with ages ranging between 11 and 60 years (mean = 31.6 years) and 13 were female with ages ranging between 20 and 65 years (mean = 38.8 years). Canal wall reconstruction (CWR)mastoidectomy was performed in 31 ears and canal wall down (CWD) mastoidectomy in 9 ears. Concha cartilage was used for ear canal wall reconstruction in 22 of the 31 CWR procedures and cortical mastoid bone was used in the remaining 9 cases. Results At 0.5 to 4 years follow up, all but one patients remained free of signs of cholesteatoma recurrence, i.e., no retraction pocket or cholesteatoma matrix. One patient, a smoker, needed revision surgery due to cholesteatoma recurrence 1.5 year after the initial operation. The recurrence rate was therefore 3.2% (1/31). Cholesteatoma recurrence was monitored using postoperative CT scans whenever possible. In the case that needed a revision procedure, a retraction pocket was identified by otoendoscopy in the pars flacida area that eventually evolved into a cholesteatoma. A pocket extending to the epitympanum filled with cholesteatoma matrix was confirmed during the revision operation, A decision to perform a modified mastoidectomy was made as the patient refused to quit smoking. The mean air-bone gap in pure tone threshold was 45 dB before surgery and 25 dB after (p < 0.05). There was no difference between using concha cartilage and cortical mastoid bone for the reconstruction regarding air-bone gap improvement, CT findings and otoendoscopic results. Conclusion CWR mastoidectomy can be used for

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

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

    A cancer researcher reviews the events surrounding the toxic waste contamination at Love Canal with emphasis on the political nature of the controversy about its health impact. Antagonism between the community and the New York State Department of Health was fueled by several factors: the state's awareness that it gained from delay in investigation, disagreement on health problems to be studied, control over the information gathering process, silencing of opposition opinion, and the violation of norms of scientific behavior. The author calls for the establishment of standards of ethical behavior for scientists in such situations, standards for conflict resolution, and means of appeal for those injured.

  1. Application of thorium-normalized airborne radio-spectrometric survey data of Wadi Araba area, North-eastern Desert, Egypt, as a guide to the recognition of probable subsurface petroleum accumulations

    A new exploration method has been developed by Saunders et al. (Geophysics 58(10) (1993) 1417) using surface and aerial gamma-ray spectral measurements in prospecting for petroleum in stratigraphic and structural traps. Wadi Araba area, North-eastern Desert, Egypt, was selected to apply this method on its recorded aerial gamma-ray spectrometric survey data, due to its distinct stratigraphic and structural setting as well as its situation in close connection with the Gulf of Suez, which represents one of the important sites of oil production in Egypt. The three variables (eU, eTh, and K) registered for the whole study area, in the form of three contour maps, were digitized along the flight paths every 1.0 km. The DRAD arithmetic means plus three standard deviations for the data set were computed. Any single profile value greater than this quantity should have a probability of 99.87% that it represents a valid anomaly and is not caused by random variations in the background values. The use of these criteria has identified one flight line which has a valid anomaly that is not caused by random variations in the background values. This might indicate a prospective possibility for petroleum accumulation in the Wadi Araba area, North-eastern Desert, Egypt.

    Spinal stenosis is a narrowing of the spinal canal by a combination of bone and soft tissues, which can lead to mechanical compression of spinal nerve roots or the dural sac. The lumbal spinal compression of these nerve roots can be symptomatic, resulting in weakness, reflex alterations, gait disturbances, bowel or bladder dysfunction, motor and sensory changes, radicular pain or atypical leg pain and neurogenic claudication. The anatomical presence of spinal canal stenosis is confirmed radiologically with computerized tomography, myelography or magnetic resonance imaging and play a decisive role in optimal patient-oriented therapy decision-making. (orig.) [German] Die Spinalkanalstenose ist eine umschriebene, knoechern-ligamentaer bedingte Einengung des Spinalkanals, die zur Kompression der Nervenwurzeln oder des Duralsacks fuehren kann. Die lumbale Spinalkanalstenose manifestiert sich klinisch als Komplex aus Rueckenschmerzen sowie sensiblen und motorischen neurologischen Ausfaellen, die in der Regel belastungsabhaengig sind (Claudicatio spinalis). Die bildgebende Diagnostik mittels Magnetresonanztomographie, Computertomographie und Myelographie spielt eine entscheidende Rolle bei der optimalen patientenbezogenen Therapieentscheidung. (orig.)

    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.

    Four successive oil discharges were observed during the last 2 years following the recording of the earthquake events. Oil slicks were clearly observed in the thermal band of the Enhanced Thematic Mapper images acquired during the discharge events. Lineaments were extracted from the ETM+ image data and SRTM (DEM). The seismic activity is conformable in time and spatially related to active major faults and structural lineaments. The concerned site was subjected to a numerous earthquakes with magnitudes ranging from 3 to 5.4 Mb. Aeromagnetic field data analyses indicated the existence of deep major faults crossing the Gebel El-Zeit and the Mellaha basins (oil reservoirs). The magnetic field survey showed major distinctive fault striking NE-SW at 7000 m depth. Occurrence of these faults at great depth enables the crude oil to migrate upward and appear at the surfaces as oil seeps onshore and as offshore slicks in the Gemsa-Hurghada coastal zone.

    Full Text Available El Ain El Sukhna area was selected in the last ten years to initiate many governmental and investmental programs. The different activities in that area depend mainly on the groundwater of the Quaternary aquifer, which forms the main water bearing strata. In the present work, twenty one geoelctrical soundings using the Schlumberger configuration are carried out at selected sites especially in missing parts from wells to delineate the groundwater setting in such sites. Eight of them are conducted in the close vicinity of water wells, where lithologs and pumping test data of these wells are available to relate hydrologic and geoelctric measurements. The pumping tests data are analyzed by using AQTESOLV program and the geolectrical sounding data were interpreted by partial curve matching technique to obtain the initial parameters. The results indicated that, the transmissivity is found to be closely related with transverse resistance and the hydraulic conductivity with average transverse resistivity, while the salinity is inversely related with resistivity. Finally, priority map for drilling water wells is constructed to make the results more illustrative and useful for decision maker. The promising area for drilling is located at the western portion of the study region.

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

    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.

    Bell, Peter M.

    When in 1978, the New York State Department of Health issued the report, ‘Love Canal—Public Health Time Bomb,’ the serious effects of chemical waste contamination in the Love Canal area became an issue of national concern. A few ‘studies’ since then have produced results in concert with those of initial reports that described ‘conditions of acute health effects’ as being linked to hazardous wastes incorporated in landfill in the Love Canal site near Niagara Falls, New York. Now that a ‘blue ribbon’ panel of experts from the medical sciences has reviewed the problems of Love Canal, however, a different view has emerged. The ‘Report of the Governors' Panel to Review Scientific Studies and the Development of Public Policy on Problems Resulting from Hazardous Wastes,’ transmitted in October of this year, identifies the following factors about the health effects at Love Canal:

    A crucial step during a dental root canal treatment is irrigation, where an antimicrobial fluid is injected into the root canal system to eradicate all bacteria. Agitation of the fluid using an ultrasonically vibrating miniature file has shown significant improvement in cleaning efficacy over conventional syringe irrigation. However, the physical mechanisms underlying the cleaning process, being acoustic streaming, cavitation or chemical activity, and combinations thereof, are not fully understood. High-speed imaging allows us to visualize the flow pattern and cavitation in a root canal model at microscopic scales, at timescales relevant to the cleaning processes (microseconds). MicroPIV measurements of the induced acoustic streaming are coupled to the oscillation characteristics of the file as simulated numerically and measured with a laser vibrometer. The results give new insight into the role of acoustic streaming and the importance of the confinement for the cleaning of root canals.

  15. Horizontal Canal Benign Positional Vertigo

    Directory of Open Access Journals (Sweden)

    Mohtaram Najafi

    1998-03-01

    Full Text Available Benign paroxysmal positional vertigo (BPPV is a syndrome characterized by transient episodes of vertigo in association with rapid changes in head position in Dix-Halpike Maneuver. This kind of vertigo is thought to be caused by migration of otoconial debris into canals other than the posterior canal, such as the anterior or lateral canals. It is also theoretically possible for many aberrant patterns of BPPV to occur from an interaction of debris in several canals, location of debris within the canal, and central adaptation patterns to lesions. The symptoms of BPPV are much more consistent with free-moving densities (canaliths in the posterior SCC rather than fixed densities attached to the cupula. While the head is upright, the particles sit in the PSC at the most gravity-dependent position. The best method to induce and see vertigo and nystagmus in BPPV of the lateral semicircular canal is to rotate head 90°while patient is in the supine position, nystagmus would appear in the unaffected side weaker but longer than the affected side. canal paresis has been described in one third of the patients with BPPV. Adaptation which is one of the remarkable features of BPPV in PSC is rarely seen in LSC. Rotations of 270° or 360° around the yaw axis (the so-called barbecue maneuver toward the unaffected ear are popular methods for the treatment of geotropic HC-BPPV. These maneuvers consist of sequential head turning of 90° toward the healthy side while supine. With these maneuvers, the free-floating otoconial debris migrates in the ampullofugal direction, finally entering the utricle through the nonampullated end of the horizontal canal. This kind of vertigo recovers spontaneously more rapidly and suddenly.

  17. Nuclear desalination in Egypt: activities and prospects

    International Nuclear Information System (INIS)

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

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

    Full Text Available The Atazar Canal helps to supply Madrid with water, from the rivers Lozoya, Jarama and Sorbe. The section which operates at present starts at the Torrelaguna dam and finishes at the El Goloso reservoir. Later a further section will be added, from the Atazar dam, on the Lozoya river, to link up with the control dam at Torrelaguna. The canal capacity is 16 m3/sec, and it is 43.47 km long. It has a slope of 4/10.000. The cross section is similar to that of the Jarama canal, already built. There are interconnections between this canal and the Canal Alto, which previously supplied the high and medium part of Madrid. To overcome the ground unevenness 5 syphons have been built, the most important of which is the Colmenar Goloso syphon, which is 10.88 km in length. Construction commenced on December 10, 1962, and water reached Madrid on June 15th, 1966. The initial budget for this project was 1,500 million pesetas.El canal del Atazar refuerza considerablemente el abastecimiento de aguas a Madrid, procedentes de los ríos Lozoya, Jarama y, en un próximo futuro, del Sorbe.

    2012-12-01

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

  4. Fluidmechanics of semicircular canals revisited

    Obrist, Dominik

    2008-05-01

    In this work we find the exact solution for the flow field in a semicircular canal which is the main sensor for angular motion in the human body. When the head is rotated the inertia of the fluid in the semicircular canal leads to a deflection of sensory hair cells which are part of a gelatinous structure called cupula. A modal expansion of the governing equation shows that the semicircular organ can be understood as a dynamic system governed by duct modes and a single cupular mode. We use this result to derive an explicit expression for the displacement of the cupula as a function of the angular motion of the head. This result shows in a mathematically and physically clean way that the semicircular canal is a transducer for angular velocity.

    Full Text Available INTRODUCTION: Nature seldom draws a straight line. Nowhere is thi s more apparent than in the anatomy of teeth roots and root canal systems o f human teeth. Even teeth with straight roots can harbor severely curved canals. Canal shapi ng is a critical aspect of endodontic treatment because it influences the outcome of the subsequent phases of canal irrigation and filling and the success of the treatment itself. In fact, curved canals are the most common endodontic complexity 1 . The need for some manner of root canal preparation pri or to root canal filling has long been recognized as an essential step in endodontic t reatment. Concepts concerning the role and purpose of this canal preparation, however, have differ ed remarkably at different times in the development of endodontics and in the hands of diffe rent practitioners 2

    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

  7. Computed tomography of the thoracic canal

    International Nuclear Information System (INIS)

    Under the adequate CT condition, thoracic canal was studied in twelve normal cases, nine cases of cervical myelopathy with developmental cervical canal stenosis and four cases of thoracic myelopathy with ossification of thoracic yellow ligament. The results were as follows. 1) The adequate condition for delineation of thoracic canal seemed to be nearly 400 EMI units in window width and 150 in level. Scanning angle was permitted within about 100. Bony thoracic canal was well scanned at the center of vertebral body. 2) The configulation of the normal thoracic canal was oval at Th1, Th2 levels and round at Th3-Th10 and large oval at Th11, Th12. The sagittal diameter was almost fixed at each level and the transverse diameter was large at upper and lower levels and small at middle levels. 3) Thoracic canal was narrowed in the cases of cervical myelopathy with developmental cervical canal stenosis especially in sagittal diameter, but not narrowed in transverse diameter. Three of four cases who had myelopathy with ossification of thoracic yellow ligament had narrow canals. 4) There was a good relation between sagittal diameter of cervical canal and thoracic canal. 5) There was a good relation between sagittal diameter of thoracic canal measured by conventional radiographs (Hattori's method) and CT scans. The author thinks that Hattori's method is useful to diagnose the thoracic canal stenosis. (author)

    Full Text Available Accidental injury to the facial nerve where the bony canal defects are present may result with facial nerve dysfunction during otological surgery. Therefore, it is critical to know the incidence and the type of facial nerve dehiscences in the presence of normal development of the facial canal. The aim of this study is to review the site and the type of such bony defects in 144 patients operated for facial paralysis, myringoplasty, stapedotomy, middle ear exploration for sudden hearing loss, and so forth, other than chronic suppurative otitis media with or without cholesteatoma, middle ear tumors, and anomaly. Correlation of intraoperative findings with preoperative computerized tomography was also analyzed in 35 patients. Conclusively, one out of every 10 surgical cases may have dehiscence of the facial canal which has to be always borne in mind during surgical manipulation of the middle ear. Computerized tomography has some limitations to evaluate the dehiscent facial canal due to high false negative and positive rates.

  6. Toward replacement fertility in Egypt and Tunisia.

    Eltigani, Eltigani E

    2009-09-01

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

    2009-10-01

    Sediment samples from the coastal zone of the Gulf of Suez contain a variety of organic compounds from anthropogenic and natural sources. A total of 12 surface samples of bottom sediments were collected with an Ekman grab sampler along an off-shore transect south of Ras Abu el-Darag. The samples were extracted with a mixture of dichloromethane and methanol (3:1 v/v) after drying and sieving through 250 μm mesh. The extracts were derivatized and analyzed by gas chromatography-mass spectrometry in order to characterize the chemical composition and sources of the organic components. Marine with minor terrestrial biota were the major natural sources of organic tracers and included n-alkanoic acids, sterols and saccharides (5.7-76.7%). Anthropogenic sources, from petroleum related activities, detergent usage for spill cleaning and littering, are indicated by the presence of n-alkanes with carbon preference index ≤1.0, hopanes, steranes, unresolved complex mixture of branched and cyclic hydrocarbons, alkyl nitriles, alkamides and plasticizers. Their total relative concentrations ranged from 23.3 to 97.3% of the total extracts. Petroleum residues from natural seepage may also be part of these hydrocarbons. The levels of anthropogenic inputs decrease from about 94% in coastal zone sediments to about 20% in sediments from the reef front.

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

    International Nuclear Information System (INIS)

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

    Kadelka, Claus; Adeyeye, John O; Laubenbacher, Reinhard

    2014-01-01

    The concept of a nested canalizing Boolean function has been studied over the last decade in the context of understanding the regulatory logic of molecular interaction networks, such as gene regulatory networks. Such networks are predominantly governed by nested canalizing functions. Derrida values are frequently used to analyze the robustness of a Boolean network to perturbations. This paper introduces closed formulas for the calculation of Derrida values of networks governed by Boolean nested canalizing functions, which previously required extensive simulations. Recently, the concept of nested canalizing functions has been generalized to include multistate functions, and a recursive formula has been derived for their number, as a function of the number of variables. This paper contains a detailed analysis of the class of nested canalizing functions over an arbitrary finite field. In addition, the concept of nested canalization is further generalized and closed formulas for the number of such generalized fun...

  15. Stability of guest molecules in urea canal complexes by canal polymerization

    International Nuclear Information System (INIS)

    It was found that various organic materials are attracted into urea canal by hexanediol diacrylate (HDDA) and long chain compounds. This means that materials which does not form complex by itself are induced in canal by HDDA and long chain compounds. To include with stability perfumes, insecticides, attractants and repellents in urea canal, leaf alcohol was used as a model compound for guest molecules in the canal. The leaf alcohol from the canal released gradually over many days and the release was inhibited for 15 days by long chain compounds and for 30 days by polymerized HDDA after irradiation. After releasing, the leaf alcohol in the canal remained 25 % stable for long chain compounds and 40 % for polymerized HDDA. The dose required for stabilization of leaf alcohol in the urea canal by canal polymerization of HDDA was 30 kGy. (author)

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

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

    Policy choices in the wake of recent mass protests in Egypt will determine the likelihood of civil war in the short run and the prospects for democracy in the long run. Economic conditions can be improved by international action to reduce grain-based biofuel production and finance employment generation. Creating the conditions for stable democracy requires accepting power-sharing mechanisms in which the military will have an important role.

    Egyptology has been dominated by the large quantity of written and pictorial material available. This amazing archaeology has opened up a wonderful view of the ancient Egyptian world. The importance of hieroglyphics and texts, and their interpretation, has led to other areas of archaeology playing much less prominence in the study of Egypt. Perhaps most notable in this is relative lack of the application of analytical science to answer Egyptian questions. This problem has been compounded by d...

    Cairo and northeastern Egypt experienced a rare, damaging earthquake on October 12, 1992. The earthquake, which measured 5.9 on the Richter magnitude scale, was centered near the village of Dahshur, about 18 km south of Cairo. The computed hypocentral depth of the earthquake, about 25 km, is consistent with the fact that fault rupture associated with the earthquake did not reach the surface.

    2016-04-01

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

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

    A narrow internal auditory canal (IAC) constitutes a relative contraindication to cochlear implantation because it is associated with aplasia or hypoplasia of the vestibulocochlear nerve or its cochlear branch. We report an unusual case of a narrow, duplicated IAC, divided by a bony septum into a superior relatively large portion and an inferior stenotic portion, in which we could identify only the facial nerve. This case adds support to the association between a narrow IAC and aplasia or hypoplasia of the vestibulocochlear nerve. The normal facial nerve argues against the hypothesis that the narrow IAC is the result of a primary bony defect which inhibits the growth of the vestibulocochlear nerve. (orig.)

    2012-01-01

    Full Text Available Procedural accidents leading to complications such as canal transportation have been ascribed to inapt cleaning and shaping concepts. Canal transportation is an undesirable deviation from the natural canal path. Herewith a case of apical transportation of root canal resulting in endodontic retreatment failure and its management is presented. A healthy 21-year-old young male presented discomfort and swelling associated with painful endodontically retreated maxillary incisor. Radiograph revealed periradicular radiolucency involving underfilled 11 and overfilled 12. Insufficiently obturated 11 exhibited apical transportation of canal. This type III transportation was treated by periradicular surgery and repair using white mineral trioxide aggregate (MTA. Comfortable asymptomatic patient presented uneventful healing at third and fourth month recall visits. A decrease in the size of radiolucency in radiograph supported the clinical finding. In the present case, MTA is useful in repairing the transportation defect. The result of these procedures is predictable and successful.

    Several hundred different species of bacteria are present in the human intraoral environment. Bacterial penetration of root canal dentin occurs when bacteria invade the root canal system. These bacteria may constitute a reservoir from which root canal reinfection may occur during or after endodontic treatment. The learning objective of this article is to review endodontic microbiology, update readers on the role of bacteria in pulp and periapical disease, and discuss the principles of management of infected root canal dentin. Complete debridement, removal of microorganisms and affected dentin, and chemomechanical cleansing of the root canal are suggested as being the cornerstones of successful endodontic therapy, followed by intracanal medication to remove residual bacteria, when required.

    Full Text Available Spinal canal stenosis results from progressive narrowing of the central spinal canal and the lateral recesses. Primary (congenital lumbar spinal stenosis is associated with achondroplastic dwarfism. The spinal canal may become narrowed by bulging or protrusion of the intervertebral disc annulus, herniation of the nucleus pulposus posteriorly, thickening of the posterior longitudinal ligament, hypertrophy of the facet joints, hypertrophy of the ligamentum flavum, epidural fat deposition, spondylosis of the intervertebral disc margins and uncovertebral joint hypertrophy in the neck. The central canal and the neurorecess may be compromised by tumor infiltration, such as metastatic disease, or by infectious spondylitis."nAP diameter of the normal adult cervical canal has a mean value of 17-18 mm at vertebral levels C3-5. The lower cervical canal measures 12-14 mm. Cervical stenosis is associated with an AP diameter of less than 10 mm. The thoracic spinal canal varies from 12 to 14 mm in diameter in the adult. The diameter of the normal lumbar spinal canal varies from 15 to 27 mm. Lumbar stenosis results from a spinal canal diameter of less than 12 mm in some patients; a diameter of 10 mm is definitely stenotic."nSpinal MRI is the most suitable technique for the diagnosis of spinal stenosis. The examination should be performed using thin sections (3 mm and high resolution, including the axial and sagittal planes using T1-weighted, proton-density, and T2-weighted techniques. The bony and osteophytic components are seen best using a T2-weighted gradient-echo technique."nOn MRI, findings of spinal stenosis have a variable presentation depending on the specific disease. The goal of spinal imaging is to localize the site and level of disease and to help differentiate between conditions in which patients require surgery or conservative treatment."nIn this presentation, different kinds of spinal canal stenosis and their MRI findings would be discussed.

    美国、俄罗斯以及东欧国家披露的一些档案及回忆录显示,1956年苏联第二次出兵匈牙利的原因是多方面的。匈牙利事件是对苏联在东欧控制权的严重挑战,苏共领导害怕匈牙利事件会波及整个东欧地区乃至于苏联,从而使整个苏东社会主义阵营毁于一旦。纳吉政府采取骑墙立场并越来越受反动力量的影响,特别是他已不能左右布达佩斯的局势以及美国政府所谓的"不干涉"政策等都是赫鲁晓夫再次出兵的重要原因。影响苏联决策改变的决定性促进因素是1956年10月31日苏伊士危机导致国际形势的突变,即英、法发动的侵埃战争并"频频得手",最终使苏联决心再次以武力解决匈牙利危机,因为苏联决不能让匈牙利投入北约的怀抱,或成为反苏的"桥头堡"。%According to some archives and memoirs publicly announced in America,Russia and East-European countries,there were varieties of reasons for Soviet Union's re-dispatching troops to Hungary in 1956.The Hungarian Incident was a grave challenge to Soviet control power on eastern Europe,so the current Soviet leadership feared that it might affect the whole of eastern Europe and even Soviet Union itself and break the Socialist Camp of Soviet Union and eastern Europe.Khrushchev had a series of important reasons for re-dispatching troops,including Nagi government's fence-sitting attitude and more and more exposure to reactionary effects,Nagy losing his control over the situation that was happening in Budapest and the U.S.Government's so-called non-intervention policy.But the actually decisive impelling element that caused Soviet to change its decision was the Suez Crisis,which led to a sudden change of the world order.Britain and France launched an aggressive war against Egypt and "made successive progressions",which froze Soviet Union's determination to cope with Hungarian Crisis again by force in case Hungary

    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

  20. Astronomy at Nabta Playa, Southern Egypt

    McKim Malville, J.

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

  1. Panama Canal Watershed Experiment- Agua Salud Project

    2010-01-01

    The Agua Salud Project utilizes the Panama Canal’s (Canal) central role in world commerce to focus global attention on the ecosystem services provided by tropical forests. The Canal was one of the great engineering projects in the world. Completed in 1914, after almost a decade of concerted effort, its 80 km length greatly shortened the voyage between the Atlantic and Pacific Oceans. An entire class of ships, the Panamax, has been constructed to maximize the amount of cargo that can be carried in a Canal passage. In today’s parlance, the Canal is a “green” operation, powered largely by water (Table 1). The locks, three pairs on each end with a net lift of 27 meters, are gravity fed. For each ton of cargo that is transferred from ocean to ocean, about 13 tons of water (m3) are used. Lake Gatún forms much of the waterway in the Canal transect. Hydroelectricity is generated at the Gatún dam, whenever there is surplus water, and at Madden Dam (completed in 1936) when water is transferred from Lake Alhajuela to Lake Gatún. The Canal watershed is the source of drinking water for Panama City and Colon City, at either end of the Canal, and numerous towns in between.

  2. How to bond to root canal dentin

    Nica, Luminita; Todea, Carmen; Furtos, Gabriel; Baldea, Bogdan

    2014-01-01

    Bonding to root canal dentin may be difficult due to various factors: the structural characteristic of the root canal dentin, which is different from that of the coronal dentin; the presence of the organic tissue of the dental pulp inside the root canal, which has to be removed during the cleaning-shaping of the root canal system; the smear-layer resulted after mechanical instrumentation, which may interfere with the adhesion of the filling materials; the type of the irrigants used in the cleaning protocol; the type of the sealer and core material used in the obturation of the endodontic space; the type of the materials used for the restoration of the endodontically treated teeth. The influence of the cleaning protocol, of the root canal filling material, of the type of the adhesive system used in the restoration of the treated teeth and of the region of the root canal, on the adhesion of several filling and restorative materials to root canal dentin was evaluated in the push-out bond strength test on 1-mm thick slices of endodontically treated human teeth. The results showed that all these factors have a statistically significant influence on the push-out bond strength. Formation of resin tags between radicular dentin and the investigated materials was observed in some of the samples at SEM analysis.

  3. Isotope techniques in the study of groundwater in the eastern Nile Delta and the transport of pollution from drainage water into Lake Manzala, Egypt

    International Nuclear Information System (INIS)

    Seventy-two water samples were collected from eastern Nile Delta groundwater, Lake Manzala, surface water and main drainage stations during 1993-1995. The water samples were analysed for major, minor and tracer elements and for oxygen-18 and deuterium. The hydrochemical studies indicate that the groundwater of the eastern Delta can be classified into three groups of low, medium and high salinity. The fresh water is mostly encountered near the Nile and near irrigation canals in the south. The brackish and saline water occurs near the Bitter Lakes, the Gulf of Suez and the Mediterranean Sea. The salinity is attributed to the leaching of terrestrial salts and to seawater intrusion. Nitrate concentration was found to be relatively high because of extensive fertilizer use. In general, the stable isotope contents of groundwater differ widely depending upon the contribution of each recharging source (present Nile, old Nile, precipitation, seawater intrusion and possibly palaeowater contribution in some localized areas). Investigation of Lake Manzala revealed that the water salinity is rather inhomogeneous, and high concentrations of trace elements were detected, which could be attributed to drainage water discharging into the lake. A stable isotope balance was developed to estimate seepage and evaporation from the lake. (author)

  6. Mercury Removal from Natural Gas in Egypt

    International Nuclear Information System (INIS)

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

    2016-01-01

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

    York, George K; Steinberg, David A

    2010-01-01

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

    2008-01-01

    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.

  16. Contribution of geophysical data in delineating the active subsurface structures along the southeastern Mediterranean and northern Egypt

    2016-04-01

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

    1996-12-31

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

  19. Policy aspects of electricity and the environment in Egypt

    International Nuclear Information System (INIS)

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

  20. The fluid mechanics of root canal irrigation.

    Science.gov (United States)

    Gulabivala, K; Ng, Y-L; Gilbertson, M; Eames, I

    2010-12-01

    Root canal treatment is a common dental operation aimed at removing the contents of the geometrically complex canal chambers within teeth; its purpose is to remove diseased or infected tissue. The complex chamber is first enlarged and shaped by instruments to a size sufficient to deliver antibacterial fluids. These irrigants help to dissolve dying tissue, disinfect the canal walls and space and flush out debris. The effectiveness of the procedure is limited by access to the canal terminus. Endodontic research is focused on finding the instruments and clinical procedures that might improve success rates by more effectively reaching the apical anatomy. The individual factors affecting treatment outcome have not been unequivocally deciphered, partly because of the difficulty in isolating them and in making the link between simplified, general experimental models and the complex biological objects that are teeth. Explicitly considering the physical processes within the root canal can contribute to the resolution of these problems. The central problem is one of fluid motion in a confined geometry, which makes the dispersion and mixing of irrigant more difficult because of the absence of turbulence over much of the canal volume. The effects of treatments can be understood through the use of scale models, mathematical modelling and numerical computations. A particular concern in treatment is that caustic irrigant may penetrate beyond the root canal, causing chemical damage to the jawbone. In fact, a stagnation plane exists beyond the needle tip, which the irrigant cannot penetrate. The goal is therefore to shift the stagnation plane apically to be coincident with the canal terminus without extending beyond it. Needle design may solve some of the problems but the best design for irrigant penetration conflicts with that for optimal removal of the bacterial biofilm from the canal wall. Both irrigant penetration and biofilm removal may be improved through canal fluid

    Heading Abstract.The aim of this study was to assess imaging findings of posterior semicircular dehiscence on computed tomography and to evaluate incidence of posterior and superior semicircular canal dehiscence in patients presenting with vertigo, sensorineuronal hearing loss or in a control group without symptoms related to the inner ear. Computed tomography was performed in 507 patients presenting either with vertigo (n=128; 23 of these patients suffered also from sensorineuronal hearing loss), other symptoms related to the inner ear, such as hearing loss or tinnitus (n=183) or symptoms unrelated to the labyrinth (n=196). All images were reviewed for presence of dehiscence of the bone, overlying the semicircular canals. Twenty-nine patients had superior semicircular canal dehiscence. Of these patients, 83% presented with vertigo, 10% with hearing loss or tinnitus and the remaining 7% with symptoms unrelated to the inner ear. In 23 patients dehiscence of the posterior semicircular canal was encountered. Of these patients, 86% presented with vertigo, 9% with hearing loss or tinnitus and 5% with symptoms unrelated to the inner ear. Defects of the bony overly are found at the posterior semicircular canal, in addition to the recently introduced superior canal dehiscence syndrome. Significant prevalence of vertigo in these patients suggests that posterior semicircular canal dehiscence can cause vertigo, similar to superior semicircular canal dehiscence. (orig.)

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

    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.

  11. Economic study of rice irradiation in egypt

    International Nuclear Information System (INIS)

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

    Aims of this work were to examine lateral canals in extracted teeth, to propose a new technique to produce artificial lateral canals, and to compare two obturation techniques. Cleared roots were examined to record measure and shape of lateral canals. Artificial lateral canals were prepared on human demineralized teeth before final clearing. Specimens were divided in two groups: canals of group 1 were filled with Schilder's technique, canals of group 2 were filled with vertical compaction with apical backfilling. Stereomicroscopic analysis of lateral canal filling revealed lower filling rates in apical canals compared to coronal ones and higher filling rates with "vertical compaction with apical backfilling" compared to Schilder's group. The tested procedure appears to be a reliable technique to obtain standardized lateral canals and to compare filling procedures.

    The author invested the gonial angle, the angle of mandibular and mental canal to the lower border of the mandible, and a relationship of the position of the mandibular canal to the root apex of the posterior teeth and the cortical plate of the lower of the mandible. The materials consisted of 458 pantomograms in male and female aged 11-40 and divided into 5 groups at year intervals and subdivided into 3 groups by gonial angle. The results were as follows: 1. The gonial angle decreased with age, but slight increase occurred over 26-30 years. 2. The average angle of the mandibular canal to the lower border of the mandible was 151.6 degree and did not correlate with age. 3. The average angle of the mental canal to the lower border of the mandible was 36.9 degree and didn't correlate with age. 4. The angles of mandibular and mental canal to the lower border of mandible correlated with gonial angle. 5. The distance from the root apex of the posterior teeth to the upper wall mandibular canal was most short at the region of the distal root of the mandibular second and increased with age at the region of the mandibular second molar. 6. The distance from the lower wall of the mandibular canal to the cortical plate of the lower border of the mandibule was most short at the region of the mesial root of the mandibular first molar and didn't correlate with age.

  14. Geotechniques of landfill design in Egypt

    International Nuclear Information System (INIS)

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

    Full Text Available This paper is a conceptual study that attempts to analyse the possible effects of the development of the Kra Isthmus Canal on ASEAN relations. The Kra Canal would constitute a mega-project, a passageway that would connect the Andaman Sea and the Gulf of Thailand at the Isthmus of Kra, Thailand. Although the proposed Kra Canal is projected to provide many economic and trade benefits to Thailand, and to the region as a whole, steps toward its development have yet to be taken. There has been much debate over the costs for trade, the costs for the environment, national and regional security concerns, as well as major concerns related to political and economic relations in the region. Therefore, one of the main purposes of this study is to contribute to the debate on the possible impact of the devel-opment of the Kra Canal on ASEAN’s regional relations. In particular, it proposes that the development of the Kra Canal could threaten regional solidarity as it would physically divide maritime Southeast Asia from main-land Southeast Asia, which would ultimately result in an economic, cultural and political divide of ASEAN itself.

    Seventy-three fungal species belonging to forty-three genera were isolated from 40 samples of Saccharrum officinarum (collected from Naage-Hamadi canal in Qena Governorate, Egypt). Aspergillus, Trichoderma, Mucor and Pythium were the most common genera on the two isolation media. The dominant species of Aspergillus were A. niger, A. flavus, A. ustus, A. terreus and A. wentii. Some species were dominant on 40 g/l sucrose such as Aspergillus niger, A. flavus, Emericella nidulans, Trichoderma viride, Torula herbarum and Mamaria echinoeotryoides, while the dominant species on 10 g/l glucose were Mucor circinelloides, Aspergillus niger, Torula herbarum and Trichoderma viride. Mycotoxins including aflatoxins B1, B2, G1 and G2, zearalenone and diacetoxyscirpenol were detected in the examined samples of Saccharrum officinarum. The mycelial growth of A. flavus, A. niger, Fusarium moniliforme and Torula herbarum decreased with the increase in Dimethoate concentrations, although 25 ppm was less effective than the higher levels of the insecticide (75~200 ppm). Dimethoate stimulated the activity of Go-T in A. niger, F. moniliforme and T. harbarum, while the Go-T activity was inhibited in A. flavus with the Dimethoate treatments. PMID:24049478

    It is difficult to distinguish a tectal carcinoma with anal metastases from coexistent synchronous anorectal carcinomas.The therapeutic strategy for rectal and anal carcinoma is so different that it should be clearly identified.Here,we report on the case of a 63-year-old man who presented with an upper-third rectal adenocarcinoma.Five months after resection,he developed an adenocarcinoma in the anal canal.The histological slides of both tumors were reviewed and immunohistochemical studies for cytokeratins(CKs)7 and 20 were performed.The index tumor demonstrated CK 7-/CK 20+and the second showed CK7+/CK20+.For this reason,we believe the present case had synchronous adenocarcinomas arising from anal canal and the rectum separately.It is very important to difierentiate the anorectal lesions pathologically because of the impact on the therapeutic options available,especially for the lesion arising in the anal canal.

    Boolean network models have gained popularity in computational systems biology over the last dozen years. Many of these networks use canalizing Boolean functions, which has led to increased interest in the study of these functions. The canalizing depth of a function describes how many canalizing variables can be recursively "picked off", until a non-canalizing function remains. In this paper, we show how every Boolean function has a unique algebraic form involving extended monomial layers and a well-defined core polynomial. This generalizes recent work on the algebraic structure of nested canalizing functions, and it yields a stratification of all Boolean functions by their canalizing depth. As a result, we obtain closed formulas for the number of n-variable Boolean functions with depth k, which simultaneously generalizes enumeration formulas for canalizing, and nested canalizing functions.

  10. Surgical endodontic management of infected lateral canals of maxillary incisors

    Science.gov (United States)

    2015-01-01

    This case report presents surgical endodontic management outcomes of maxillary incisors that were infected via the lateral canals. Two cases are presented in which endodontically-treated maxillary central incisors had sustained lateral canal infections. A surgical endodontic treatment was performed on both teeth. Flap elevation revealed vertical bone destruction along the root surface and infected lateral canals, and microscopy revealed that the lateral canals were the origin of the lesions. After the infected lateral canals were surgically managed, both teeth were asymptomatic and labial fistulas were resolved. There were no clinical or radiographic signs of surgical endodontic management failure at follow-up visits. This case report highlights the clinical significance and surgical endodontic management of infected lateral canal of maxillary incisor. It is important to be aware of root canal anatomy variability in maxillary incisors. Maxillary central incisors infected via the lateral canal can be successfully managed by surgical endodontic treatment. PMID:25671217

    1991-01-01

    The root canal therapy of the curved canals is a complex operative procedure. Therefore 260 root canals were analysed radiologically to determine the frequency and the most common localisation of the root canal curvature. The frequency of the curved canals averaged at 59%, being greater in the sample of posterior than in the anterior teeth (p less than 0.05). The root canal curvature was most frequently localised at the apical third part (53.9%), followed by the cervical (33.3%) and the middle (12.8%) third part. The apical curvature was predominant in the sample of the anterior, while the cervical predominant (45.2%) in the sample of the posterior teeth. This study pointed out that the frequency of the curved canals is rather high. Consequently, the necessity for practising the modern root canal preparation techniques, bearing in mind their potential danger, is emphasized. PMID:1819932

    On February 25, 2006, the French government took the decision of merging together Gaz de France and Suez energy companies as an answer to Enel's project of takeover bid on Suez. This document wonders about: the real motivations of Gaz de France (the French gas utility) privatization, the possible intervention of public authorities in Enel and Veolia companies project of controlling the Suez group, the governing way of the share-holding government and the preservation of its industrial interests, and the consequences for consumers. Therefore, the creation of a parliamentary inquiry commission is requested to shade light on these different points and to give notice of any bad practices in this affair. (J.S.)

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

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

    Mahmoud, Salah

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

  20. Who Benefits from Public Healthcare Subsidies in Egypt?

    Directory of Open Access Journals (Sweden)

    Ahmed Shoukry Rashad

    2015-11-01

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

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

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

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

    International Nuclear Information System (INIS)

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

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

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

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

  7. Computed tomography of the thoracic canal. Experimental and clinical studies

    Under the adequate CT condition, thoracic canal was studied in twelve normal cases, nine cases of cervical myelopathy with developmental cervical canal stenosis and four cases of thoracic myelopathy with ossification of thoracic yellow ligament. The results were as follows. 1) The adequate condition for delineation of thoracic canal seemed to be nearly 400 EMI units in window width and 150 in level. Scanning angle was permitted within about 10/sup 0/. Bony thoracic canal was well scanned at the center of vertebral body. 2) The configulation of the normal thoracic canal was oval at Th/sub 1/, Th/sub 2/ levels and round at Th/sub 3/-Th/sub 10/ and large oval at Th/sub 11/, Th/sub 12/. The sagittal diameter was almost fixed at each level and the transverse diameter was large at upper and lower levels and small at middle levels. 3) Thoracic canal was narrowed in the cases of cervical myelopathy with developmental cervical canal stenosis especially in sagittal diameter, but not narrowed in transverse diameter. Three of four cases who had myelopathy with ossification of thoracic yellow ligament had narrow canals. 4) There was a good relation between sagittal diameter of cervical canal and thoracic canal. 5) There was a good relation between sagittal diameter of thoracic canal measured by conventional radiographs (Hattori's method) and CT scans. The author thinks that Hattori's method is useful to diagnose the thoracic canal stenosis.

    To identify and evaluate the normal anatomy of nerve canals in the fundus of the internal auditory canal which can be visualized on high-resolution temporal bone CT. We retrospectively reviewed high-resolution (1 mm thickness and interval contiguous scan) temporal bone CT images of 253 ears in 150 patients who had not suffered trauma or undergone surgery. Those with a history of uncomplicated inflammatory disease were included, but those with symptoms of vertigo, sensorineural hearing loss, or facial nerve palsy were excluded. Three radiologists determined the detectability and location of canals for the labyrinthine segment of the facial, superior vestibular and cochlear nerve, and the saccular branch and posterior ampullary nerve of the inferior vestibular nerve. Five bony canals in the fundus of the internal auditory canal were identified as nerve canals. Four canals were identified on axial CT images in 100% of cases; the so-called singular canal was identified in only 68%. On coronal CT images, canals for the labyrinthine segment of the facial and superior vestibular nerve were seen in 100% of cases, but those for the cochlear nerve, the saccular branch of the inferior vestibular nerve, and the singular canal were seen in 90.1%, 87.4% and 78% of cases, respectiveIy. In all detectable cases, the canal for the labyrinthine segment of the facial nerve was revealed as one which traversed anterolateralIy, from the anterosuperior portion of the fundus of the internal auditory canal. The canal for the cochlear nerve was located just below that for the labyrinthine segment of the facial nerve, while that canal for the superior vestibular nerve was seen at the posterior aspect of these two canals. The canal for the saccular branch of the inferior vestibular nerve was located just below the canal for the superior vestibular nerve, and that for the posterior ampullary nerve, the so-called singular canal, ran laterally or posteolateralIy from the posteroinferior aspect of

  12. Seismic hazard assessments at Islamic Cairo, Egypt

    2015-12-01

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

    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).

  14. The prospective nuclear desalination market in Egypt

    International Nuclear Information System (INIS)

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

    2008-04-01

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

    Seda Kundak

    2011-10-01

    Full Text Available It was late April 2011 when “the Crazy Project - Canal Istanbul” was proposed by the Prime Minister of Turkey, during his election campaign.  Although the idea of an artificial canal is not new, since it is initiated without any consensus between the people and institutions in Istanbul, the project immediately set a large number of debates. These vary from the legitimacy of decentralization of governance, to potential impacts of the canal on international politics, economy, environment and urban life.  Regarding past infrastructure projects in Istanbul, such large scale investments have caused extensive acceleration in construction sector in one hand and social and economic shifts on the other.  In this paper, the Canal Istanbul Project is evaluated according to basic motivations and claims of the PM, multi-perspective view through challenges and limitation that the project is likely to face with and speculations on implementation approach. The final discussion on the project is based on benefits/losses of Istanbul once the project will be implemented.

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

    Science.gov (United States)

    Lane, S D

    1997-06-01

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

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

    2016-06-01

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

    Objectives: Lumbar punctures (LPs) are frequently performed in neonates and often result in traumatic haemorrhagic taps. Knowledge of the distance from the skin to the middle of the spinal canal (mid-spinal canal depth - MSCD) may reduce the incidence of traumatic taps, but there is little data in extremely premature or low birth weight neonates. Here, we determined the spinal canal depth at post-mortem in perinatal deaths using magnetic resonance imaging (MRI). Patients and methods: Spinal canal depth was measured in 78 post-mortem foetuses and perinatal cases (mean gestation 26 weeks; mean weight 1.04 kg) at the L3/L4 inter-vertebral space at post-mortem MRI. Both anterior (ASCD) and posterior (PSCD) spinal canal depth were measured; MSCD was calculated and modelled against weight and gestational age. Results: ASCD and PSCD (mm) correlated significantly with weight and gestational age (all r > 0.8). A simple linear model MSCD (mm) = 3 Multiplication-Sign Weight (kg) + 5 was the best fit, identifying an SCD value within the correct range for 87.2% (68/78) (95% CI (78.0, 92.9%)) cases. Gestational age did not add significantly to the predictive value of the model. Conclusion: There is a significant correlation between MSCD and body weight at post-mortem MRI in foetuses and perinatal deaths. If this association holds in preterm neonates, use of the formula MSCD (mm) = 3 Multiplication-Sign Weight (kg) + 5 could result in fewer traumatic LPs in this population.

    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

    Objective Dorello's canal was first described by Gruber in 1859, and later by Dorello. Vail also described the anatomy of Dorello's canal. In the preceding century, Dorello's canal was clinically important, in understanding sixth nerve palsy and nowadays it is mostly important for skull base surgery. The understanding of the three dimensional anatomy, of this canal is very difficult to understand, and there is no simple explanation for its anatomy and its relationship with adjacent structures. We present a simple, Lego-like, presentation of Dorello's canal, in a stepwise manner. Materials and Methods Dorello's canal was dissected in five formalin-fixed cadaver specimens (10 sides). The craniotomy was performed, while preserving the neural and vascular structures associated with the canal. A 3D model was created, to explain the canal's anatomy. Results Using the petrous pyramid, the sixth nerve, the cavernous sinus, the trigeminal ganglion, the petorclival ligament and the posterior clinoid, the three-dimensional structure of Dorello's canal was defined. This simple representation aids in understanding the three dimensional relationship of Dorello's canal to its neighboring structures. Conclusion Dorello's canal with its three dimensional structure and relationship to its neighboring anatomical structures could be reconstructed using a few anatomical building blocks. This method simplifies the understanding of this complex anatomical structure, and could be used for teaching purposes for aspiring neurosurgeons, and anatomy students. PMID:23730547

  8. Research on Canal System Operation Based on Controlled Volume Method

    2009-10-01

    Full Text Available An operating simulation mode based on storage volume control method for multireach canal system in series was established. In allusion to the deficiency of existing controlled volume algorithm, the improved algorithm was proposed, that is the controlled volume algorithm of whole canal pools, the simulation results indicate that the storage volume and water level of each canal pool can be accurately controlled after the improved algorithm was adopted. However, for some typical discharge demand change operating conditions of canal, if the controlled volume algorithm of whole canal pool is still adopted, then it certainly will cause some unnecessary regulation, and consequently increases the disturbed canal reaches. Therefor, the idea of controlled volume operation method of continuous canal pools was proposed, and its algorithm was designed. Through simulation to practical project, the results indicate that the new controlled volume algorithm proposed for typical operating condition can comparatively obviously reduce the number of regulated check gates and disturbed canal pools for some typical discharge demand change operating conditions of canal, thus the control efficiency of canal system was improved. The controlled volume method of operation is specially suitable for large-scale water delivery canal system which possesses complex operation requirements.

    The flowability of a root canal sealer is clinically important because it improves the penetration of the sealer into the complex root canal system. The purpose of this study was to compare the flowabilities of four root canal sealers, measured using the simple press method (ISO 6876), and their viscosities, measured using a strain-controlled rheometer. A newly developed, calcium phosphate-based root canal sealer (Capseal) and three commercial root canal sealers (AH Plus, Sealapex and Pulp Canal Sealer EWT) were used in this study. The flowabilities of the four root canal sealers were measured using the simple press method (n55) and their viscosities were measured using a strain-controlled rheometer (n55). The correlation between these two values was statistically analysed using Spearman’s correlation test. The flow diameters and the viscosities of the root canal sealers were strongly negatively correlated (r520.8618). The viscosity of Pulp Canal Sealer EWT was the lowest and increased in the following order:AH Plus,Sealapex,Capseal (P,0.05). All of the tested root canal sealers showed characteristic time-and temperature-dependent changes in their rheological properties. The viscosities measured using the strain-controlled rheometer were more precise than the flowabilities measured using the simple press method, suggesting that the rheometer can accurately measure the rheological properties of root canal sealers.

  11. Water quality of the Boca Raton canal system and effects of the Hillsboro Canal inflow, southeastern Florida, 1990-91

    Science.gov (United States)

    McKenzie, D.J.

    1995-01-01

    The City of Boca Raton in southeastern Palm Beach County, Florida, is an urban residential area that has sustained a constant population growth with subsequent increase in water use. The Boca Raton network of canals is controlled to provide for drainage of excess water, to maintain proper coastal ground-water levels to prevent saltwater intrusion, and to recharge the surficial aquifer system from which the city withdraws potable water. Most of the water supplied to the Boca Raton canal system and the surficial aquifer system, other than rainfall and runoff, is pumped from the Hillsboro Canal. The Biscayne aquifer, principal hydrogeologic unit of the surficial aquifer system, is highly permeable and there is a close relation between water levels in the canals and the aquifer. The amount of water supplied by seepage from the conservation areas is unknown. Because the Hillsboro Canal flows from Lake Okeechobee and Water Conservation Areas 1 and 2, which are places of more highly mineralized ground water and surface water, the canal is a possible source of contamination. Water samples were collected at 10 canal sites during wet and dry seasons and analyzed for major inorganic ions and related characteristics, nutrients, and trace elements. All concentrations were generally within or less than the drinking-water standards established by the Florida Department of Environmental Protection. The high concentrations of sodium and chloride that were detected in samples from the Boca Raton canal system are probably from the more mineralized water of the Hillsboro Canal. Other water-quality data, gathered from various sources from 1982 through 1991, did not indicate any significant changes nor trends. The effects of the Hillsboro Canal on the water quality of the Boca Raton canal system are indicated by increased concentrations of sodium, chloride, dissolved solids, and total organic carbon. Concentrations of the constituents in the canal water generally decrease with distance

For localized diseases, the treatment is based on radiotherapy with or without chemotherapy (5-FU and cisplatin or mitomycin), according to tumour and nodal extension. The recommended treatment dose is 45 Gy in the anal canal, the mesorectum, para-rectal lymph nodes, and inguinal lymph nodes. An additional dose of 15 to 20 Gy is delivered in the initial tumour for good responders. Salvage surgery is necessary in case of poor response. The organs at risk to be considered are bladder, femur heads, small intestine and vulva. The objective of this work is to summarize the epidemiological and radio-anatomic and prognostic characteristics of this tumour. The conformal radiotherapy technique is illustrated by a case report.

    Background. Ewing sarcoma (ES) is a high-grade malignant tumor that has skeletal and extraskeletal forms and consists of small round cells. In the head and neck region, reported localization of extraskeletal ES includes the larynx, thyroid gland, submandibular gland, nasal fossa, pharynx, skin, and parotid gland, but not the external ear canal. Methods. We present the unique case of a 2-year-old boy with extraskeletal ES arising from the external ear canal, mimicking auricular hematoma. Results. Surgery was performed and a VAC/IE (vincristine, adriamycin, cyclophosphamide alternating with ifosfamide, and etoposide) regimen was used for adjuvant chemotherapy for 12 months. Conclusion. The clinician should consider extraskeletal ES when diagnosing tumors localized in the head and neck region because it may be manifested by a nonspecific clinical picture mimicking common otorhinolaryngologic disorders.

    Squamous cell carcinoma ofthe anal canal represents 1.5% of all malignancies affectingthe gastrointestinal tract. Over the past 20 years dramatic changes have been seen in both the epidemiological distribution of the disease and in the therapeutic modalities utilised to manage it. CLINICAL MANAGEMENT: Historically abdominoperineal resection had been the treatment of choice with local resection reserved for early stage disease. Work by Nigro et al. has revolutionised how we currently manage carcinoma of the anal canal, demonstrating combined modality chemoradiotherapy as an appropriate alternative to surgical resection with the benefit of preserving sphincter function. Surgery is then reserved for recurrent disease with salvage abdominoperineal resection. This article reviews current literature and highlights the changing therapeutic modalities with selected clinical cases

    1996-09-01

    Full Text Available Literature on the anatomy of the human vertebral column characterizes the shape of the lumbar vertebral canal as triangular. The purpose of the present study was to determine the precise shape of the lumbar vertebral canal. Ten lumbar vertebral columns of adult male cadavers were dissected. Two transverse sections were performed in the third lumbar vertebra. One section was performed at the level of the lower border of the ligamenta flava, and the other section was performed at the level of the pedicles. The shape of the lumbar vertebral canal at the level of the pedicles tends to be oval or circular, whereas the shape of the lumbar vertebral canal at the level of the lower border of the ligamenta flava is triangular. Thus, the shape of the human lumbar vertebral canal is not exclusively triangular, as reported in the literature. It is related to the level of the transversal section performed on the lumbar vertebra. This finding should be taken into consideration among factors involved in the spread of solutions introduced into the epidural space.A literatura sobre a anatomia da coluna vertebral descreve como sendo triangular o formato do canal vertebral na região lombar. O objetivo deste estudo é determinar a real forma do canal da coluna vertebral lombar.Dez colunas vertebrais de cadáveres de homens adultos foram dissecadas. Dois cortes transversais foram executados na terceira vértebra lombar. Um corte foi feito no nível das bordas inferiores de dois ligamentos amarelos vizinhos e o outro corte foi transversal, no nível dos pedículos. A forma do canal vertebral variou: no nível dos pedículos ela tende a ser oval ou circular e junto às bordas inferiores dos ligamentos amarelos passa a ser triangular. Portanto, a forma do canal vertebral lombar não é somente triangular; ela depende do nível em que se faz o corte transversal da vértebra. Estes achados devem ser levados em consideração entre os fatores envolvidos na difusão das

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

    International Nuclear Information System (INIS)

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

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

    Science.gov (United States)

    1994-01-01

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

    2014-04-01

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

    The Koebner phenomenon originally described the appearance of psoriatic lesions in the uninvolved skin of patients with psoriasis as a consequence of trauma. We describe a case of concurrent lichen planus and sarcoidosis in the auditory canal, which represents an unusual manifestation of the Koebner phenomenon. This is the first case of concurrent lichen planus and sarcoidosis in the head and neck region and highlights the need for biopsy to allow accurate histopathological diagnosis and treatment.

  1. Root canal filling using Resilon: a review.

    LENUS (Irish Health Repository)

    Shanahan, D J

    2011-07-01

    Root canal treatment is achieved by chemo-mechanical debridement of the root canal system followed by filling. The filling material \\'entombs\\' residual bacteria and acts as a barrier which prevents the entrance of oral microorganisms and reinfection of the root canal system through microleakage. However, filling with contemporary root filling materials such as gutta-percha offers limited long-term resistance to microorganisms; as a result other materials such as Resilon have been investigated as alternatives. The aim of this review was to analyse the literature to consider whether Resilon is a suitable root canal filling material. A MEDLINE and Cochrane library search including various keyword searches identified several papers which investigated or discussed Resilon or RealSeal\\/Epiphany. Analysis of the literature demonstrated that the bulk of the literature is in vitro in nature, based largely on leakage-type studies, and demonstrates a wide variety of methodologies with conflicting findings; as a result meaningful conclusions are difficult. Within the limit of these in vitro studies Resilon appears to perform adequately in comparison to gutta-percha, however, as a result of the questionable merit of such studies, it cannot presently be considered an evidence-based alternative to the current gold standard gutta-percha. It is imperative that before Resilon is considered as a replacement material, a better understanding of the physical properties of the resin sealer and the reality of the adhesive \\'monoblock\\' are elucidated. The literature also demonstrates a paucity of quality long-term clinical outcome studies which will need to be addressed before firm conclusions can be reached.

    2014-06-01

    Full Text Available Introduction: The purpose of this study was to evaluate the sealing ability of 3 obturation techniques in oval-shaped canals by bacterial leakage assessment. Methods: Sixty mandibular incisors with oval canals were selected after providing buccolingual and mesiodistal radiographs. The teeth were sectioned at a 10 mm distance from the apex. After instrumentation, the teeth were divided into 3 groups and the canals in the three groups were obturated with lateral condensation (G1, warm vertical condensation (G2 and thermoplasticized injectable gutta percha (G3. The teeth were exposed to human saliva. Observing the turbidity of the BHI broth for a period of 63 days the number of days required for the complete contamination of root canals was recorded. The data were analyzed using descriptive statistical methods and Kruskal-Wallis test with SPSS statistical software. Results: Warm vertical condensation (G2 needed a significantly greater average time for leakage than the two other methods. No significant differences were found between lateral condensations and thermoplasticized injectable G.P techniques. Conclusion: warm vertical condensation provides a better seal against bacterial leakage than lateral condensation and obtura II method in obturating oval-canals.

  6. Endoscopic posterior decompression of lumbar canal stenosis

    2013-01-01

    Full Text Available Lumbar canal stenosis (LCS is quite common. Surgery is indicated when patient fails to improve after conservative treatment. Endoscopic technique can be used in LCS and lateral recess stenosis. It can be performed in degenerative canal stenosis or with disc bulges. Bilateral severe bony canal stenosis and unstable spine are the contraindications. This procedure should be avoided in patients with a history of trauma. Detailed history and thorough physical examination should be performed to find out exact level of pathology responsible for symptoms. Patient′s symptoms must correlate with radiological findings. Magnetic resonance imaging is the investigation of choice because of its superior visualization of soft-tissue. Computed tomography scan does give a more accurate and detailed picture of the bony anatomy. Although the operative time and the complication rate could be more in the initial learning curve, the results of endoscopic decompression are comparable with conventional open procedures with the additional benefit of decreased complications and lower morbidity, when sufficient experience is gained. Complications in endoscopic surgery for LCS could be dural tears, hematomas and root and facet injury. This procedure is also associated with limitations such as steep learning curve and the contra lateral decompression may not be as good as ipsilateral side. Some of the limitations of this technique can be overcome by attending live operative workshop, practice on models and hands on cadaveric dissection. Conversion to an open procedure may be required when there is disorientation, management of dural tear and for control of bleeding.

The IMPRSS Mission protects human health and the environment in Egypt from mismanaged sealed sources, is developed jointly with MOH and EAEA, provides capabilities for managing radioactive sealed sources in Egypt, increases public awareness, provides education and training, improves emergency response capabilities, develops a permanent disposal facility, ensures the program is self-sustaining and ensures close coordination with the IAEA. Infrastructure how to manage sealed sources is discussed. It includes awareness, tracking and inventory control, security, recovery, conditioning and storage, recycling and disposal. Emergency response, regulatory reform, education and training and its targets are provided. The government of Egypt can protect the people of Egypt and is ready for emergencies. Prevention is the first line of defence and detection is the second line of defence. Adequate Emergency Response saves lives and adequate control reduces risk of mismanaged uses or deliberate misuses of sources. A Cradle-to-Grave approach is built on existing capabilities at EAEA and MOH

  11. The radiological hazards of some radionuclides in Mariout and Brullus Lakes, Egypt

    International Nuclear Information System (INIS)

    Mariout and Brullus were considered two of the highly fish productive lakes in Egypt as well as they widely used to drain huge quantities of industrial wastewater, sewage and agriculture drainage. Thousands of peoples inhabited the areas around the lakes and depend on them completely in their lives. The activities of 238U, 232Th and 40K were measured in the upper most part of the surface sediments of the two lakes using gamma ray spectrophotometery. Brullus Lake recorded significantly higher 238U and 232Th and lower 40K (17.22±2.49 Bq/kg, 10.0 ±56 Bq/kg and 299.7±17.78 Bq/kg) than Mariout Lake (12.65±1.53 Bq/kg, 7.24±0.76 Bq/kg and 518.75±46.24 Bq/kg respectively). Inversely, the mean average of absorbed dose rate (D), annual effective dose rate (mSvy-1), radium equivalent (Raeq), external hazard index (Hex) and the representative level index (Iγr) were; 32.01 nGy/h, 0.04 mSv/y, 62.95 Bq/kg, 0.17 and 0.50 at Mariout Lake higher than those in Brullus lake (26.42 nGy/h, 0.03 mSv/y, 54.25 Bq/kg, 0.15 and 0.41) respectively. The recorded and calculated values were lower than the acceptable limits published in the different localities around the world. The activity distributions of the radiological hazards show the highest intensities in the western part of Mariout Lake and decreasing gradually eastward and north eastward affecting by the drainage agriculture water from Kabary Drain, Umum Drain, S.W. Basin and Nubaria Canal. At Brullus Lake, the radiological hazard intensities were concentrated in the west and southwest influenced by Zaglul Drain, Rosetta Drain, Brembal canal, Drain 11, Drain 9, Drain 8 and partially by Drain 1 while the lowest intensities were in the north and northeast affecting by the interaction with the Mediterranean Sea. K-40 recorded positive correlations and significant linear regression relationships with radiological hazard parameters at Mariout Like meaning that 40K is the main gamma emitter in the lake, while the different

  12. Abrasive supply for ancient Egypt revealed

    International Nuclear Information System (INIS)

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

  14. Calcareous palaeosols and temples in the floodplain of Thebes, Egypt: droughts and decisions

    2014-05-01

    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

    Full Text Available Root canal irrigation is not much emphasised in endodontic therapy. Most articles discussed are on root canal shaping and obturation not much emphasis is given for irrigation. There are many irrigation solutions which are introduced into market. The primary objective of root canal therapy is the ret ention of the pulpless or pulpally involved tooth with its associated periapical tissues in a healthy state. Achievement of this objective requires that the pulpal spaces and contents be eliminated as sources of infection. As the Enterococcus faecalis is a lso found to be the most important cause for endodontic failures, the action and efficacy of fewer irrigants against E. faecalis should also be given prime importance as of others. Therefore, the introduction of an antimicrobial endodontic irrigant during root canal therapy should be given priority in the hierarchy of root canal treatment. The purpose of this article is to analyse root canal irrigants, irrigation techniques and irrigation protocol.

    Full Text Available Forty soil samples of agriculture soil were collected from two different sites in Sohag province, Egypt, during hot and cold seasons. Twenty samples were from soil irrigated with canal water (site A and twenty samples were from soil irrigated with wastewater (site B. This study aimed to compare the incidence of plasmids in bacteria isolated from soil and to investigate the occurrence of metal and antibiotic resistance bacteria, and consequently to select the potential application of these bacteria in bioremediation. The total bacterial count (CFU/gm in site (B was higher than that in site (A. Moreover, the CFU values in summer were higher than those values in winter at both sites. A total of 771 bacterial isolates were characterized as Bacillus, Micrococcus, Staphylococcus, Pseudomonas, Eschershia, Shigella, Xanthomonas, Acetobacter, Citrobacter, Enterobacter, Moraxella and Methylococcus. Minimum inhibitory concentrations (MICs of Pb+2, Cu+2, Zn+2, Hg+2, Co+2, Cd+2, Cr+3, Te+2, As+2 and Ni+2 for plasmid-possessed bacteria were determined and the highest MICs were 1200 µg/mL for lead, 800 µg/mL for both Cobalt and Arsenate, 1200 µg/mL for Nickel, 1000 µg/ml for Copper and less than 600 µg/mL for other metals. Bacterial isolates from both sites A and B showed multiple heavy metal resistance. A total of 337 bacterial isolates contained plasmids and the incidence of plasmids was approximately 25-50% higher in bacteria isolated from site (B than that from site (A. These isolates were resistance to different antibiotics. Approximately, 61% of the bacterial isolates were able to assimilate insecticide, carbaryl, as a sole source of carbon and energy. However, the Citrobacter AA101 showed the best growth on carbaryl.

    Root canal treatment is aimed at the removal of inflamed and infected tissue present in the root canal system. It will prevent the entrance of new microorganisms or nutrients in order to maintain or create a healthy environment around the root. There is sufficient evidence that shows that traditional endodontic therapy cannot make the root canal system completely free of bacteria. Moreover, it may not always result in complete healing of apical periodontitis, highlighting the need of optimizi...

    Two useful numerical values, called the Torg ratio and the spinal canal diameter (SC diameter) are widely accepted as reliable morphometric determinants of spinal stenosis. The aims of the study were to examine morphometric determinants of the cervical spinal canal on MRI in both sexes and analyse them as reliable indicators of spinal stenosis. Measurements were made on 50 MR images (sagittal T2 weighted images from C3 to C7) of the cervical spine of patients from the Emergency Centre who had undertaken MRI of the cervical spine in addition to CT for various diagnostic indications. Torg ratio, used in evaluation of the spinal canal stenosis on plain x-ray radiographs, cannot be used as a spinal canal stenosis indicator due to the gender differences in the vertebral bodies' width. Sagittal canal diameters were more spread out in males than in females. MRI enables the value of the space available for the spinal cord, (SAC) to be determined, by subtracting the sagittal diameter of the spinal cord from the sagittal diameter of the spinal canal. Not gender, but individual and level differences in the SAC values were evident (cervical cord enlargement). SAC values relied more on the spinal canal than on the spinal cord, so that the differences in the dimensions of the spinal cord accounted for less variability in the SAC values. MR imaging of the cervical spine provides more accurate cervical canal and spinal cord measurements that could serve as morphometric determinants of the cervical canal stenosis. PMID:24280784

    Full Text Available This paper summarizes the possibilities and advantages of adopting special facings for dykes and canals, and generally for all large hydraulic works, where waterproofing is of paramount importance. Technical advances in recent years have made it possible to prefabricate many facing units used in these types of works; large slabs, made in reinforced and prestressed concrete, are flexible, and watertight. Although there are many possibilities and types of facing treatments, the one described here is outstanding. It consists of narrow slabs, highly flexible, placed transversally with respect to the canal axis. They are attached with cement mortar, and the joints are finally sealed with a special mortar, called «Emboco». In this article a description is also given of a series of projects, where facing treatments have been used, which are now successfully in service. Finally some general and simple advise is given on the best procedure to apply these facing treatments in the most effective and economic manner.En este trabajo se resumen las posibilidades y ventajas que ofrecen los revestimientos especiales de diques y taludes de canales y, en general, en todas las grandes obras hidráulicas, en que la impermeabilización es de mayor importancia al tratar de conservar los caudales iniciales o la retención de aguas embalsadas, según los casos. Los progresos de las técnicas modernas, en particular la prefabricación, han permitido este tipo de revestimientos con losas de gran longitud, extremadamente flexibles e impermeables, de hormigón armado y pretensado. Aunque son muchas las posibilidades y tipos de revestimiento, destaca el que a continuación se expone: consiste en placas o losas estrechas, de gran flexibilidad, colocadas transversalmente al eje del canal sobre tongadas de mortero de cemento, y cuyas juntas se sellan, finalmente, con un mortero especial llamado «Emboco».

    Data from the New York Cancer Registry show no evidence for higher cancer rates associated with residence near the Love Canal toxic waste burial site in comparison with the entire state outside of New York City. Rates of liver cancer, lymphoma, and leukemia, which were selected for special attention, were not consistently elevated. Among the other cancers studied, a higher rate was noted only for respiratory cancer, but it was not consistent across age groups and appeared to be related to a high rate for the entire city of Niagara Falls. There was no evidence that the lung cancer rate was associated with the toxic wastes buried at the dump site.

  16. Water Environment Evolution along the China Grand Canal

    International Nuclear Information System (INIS)

    The China Grand Canal is one of the earliest canals in the world, having lasted for nearly 3000 years. Even its section canals have a rich history, such as the North-South Grand Canal that was established during the Sui Dynasty, whereas the Beijing-Hangzhou Canal was excavated during the Yuan Dynasty and the east line of the South-to-North Water Diversion. As one of the longest in the world, the China Grand Canal's total length is over 3500 kilometers. This length includes the navigable, unnavigable, and underground sections. Making the best use of situations and according to local conditions, the Chinese people harmoniously constructed the Beijing-Hangzhou Canal with nature. Tens of millions of workers took nearly 3000 years to complete the great shipping system. Navigable sections still exist for up to 900 kilometers and the volume of freight traffic is approximately 300 million tons. The canal remains the main logistical channel of the North-to-South Coal Transportation, South-to-North Water Diversion, and resources circulation. To date, China is promoting the success of heritage application. Part of these efforts is the declaration of the China Grand Canal as a World Cultural Heritage by 2014. In addition, the east route of the South-to-North Water Transfer project is planned to be navigable by 2016.

    2008-01-01

    Full Text Available INTRODUCTION Taurodontism is a morphoanatomical change in the shape of a tooth. An enlarged body of a tooth with smaller than usual roots is a characteristic feature. Internal tooth anatomy correlates with this appearance, which means that a taurodontal tooth has a large pulp chamber and apically positioned furcations. This dental anomaly may be associated with different syndromes and congenital discoders. CASE OUTLINE The case report presents the patient of a rare case of taurodontism in the mandibular second premolar with chronic periodontitis. Endodontic treatment was performed after dental history and clinical examination. Special care is required in all segments of endodontic treatment of a taurodontal tooth from the identification orifice, canal exploration, determining working length, cleaning and shaping and obturation of the root canal. Precurved K-file was used for canal exploration and location of the furcation. One mesial and one distal canal with the buccal position were identified in the apical third of the root canal. The working lengths of two canals were determined by radiographic interpretation with two K-files in each canal and verified with the apex locator. During canal instrumentation, the third canal was located in the disto-lingual position. The working length of the third canal was established using the apex locator. CONCLUSION Thorough knowledge of tooth anatomy and its variations can lead to lower percentage of endodontic failure. Each clinical case involving these teeth should be investigated carefully, clinically and radiographically to detect additional root canals. High quality radiographs from different angles and proper instrumentarium improve the quality of endodontic procedure.

    Endodontic therapy consists in cleaning and shaping the root canal system, removing organic debris and sealing the intra-canal space with permanent filling materials. The purpose of this study was to evaluate various root canal fillings in order to detect material defects, the marginal adaptation at the root canal walls and to assess the quality of the apical sealing. 21 extracted single-root canal human teeth were selected for this study. We instrumented all roots using NiTi rotary instruments. All canals were enlarged with a 6% taper size 30 GT instrument, 0,5 mm from the anatomical apex. The root canals were irrigated with 5% sodium hypochlorite, followed by 17% ethylenediaminetetraacetic acid (EDTA). After the instrumentation was completed, the root canals were obturated using a thermoplasticizable polymer of polyesters. In order to assess the defects inside the filling material and the marginal fit to the root canal walls, the conebeam micro-computed tomography (CBμCT) was used first. After the CBμCT investigation, time domain optical coherence tomography working in en face mode (TDefOCT) was employed to evaluate the previous samples. The TDefOCT system was working at 1300 nm and was doubled by a confocal channel at 970 nm. The results obtained by CBμCT revealed no visible defects inside the root-canal fillings and at the interfaces with the root-canal walls. TDefOCT investigations permit to visualize a more complex stratificated structure at the interface filling material/dental hard tissue and in the apical region.

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

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

  2. Marketing and Economic Analysis of Garlic Irradiation in Egypt

    International Nuclear Information System (INIS)

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

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

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

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

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

  19. Inflation and Inflation Uncertainty Revisited: Evidence from Egypt

    Directory of Open Access Journals (Sweden)

    Mesbah Fathy Sharaf

    2015-07-01

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

    Effective irrigant delivery and agitation are prerequisites to promote root canal disinfection and debris removal and improve successful endodontic treatment. This paper presents an overview of the currently available technologies to improve the cleaning of the endodontic space and their debridement efficacy. A PubMed electronic search was conducted with appropriate key words to identify the relevant literature on this topic. After retrieving the full-text articles, all the articles were reviewed and the most appropriate were included in this review. Several different systems of mechanical activation of irrigants to improve endodontic disinfection were analysed: manual agitation with gutta-percha cones, endodontic instruments or special brushes, vibrating systems activated by low-speed hand-pieces or by sonic or subsonic energy, use of ultrasonic or laser energy to mechanically activate the irrigants and apical negative pressure irrigation systems. Furthermore, this review aims to describe systems designed to improve the intracanal bacterial decontamination by a specific chemical action, such as ozone, direct laser action or light-activated disinfection. The ultrasonic activation of root canal irrigants and of sodium hypochlorite in particular still remains the gold standard to which all other systems of mechanical agitation analyzed in this article were compared. From this overview, it is evident that the use of different irrigation systems can provide several advantages in the clinical endodontic outcome and that integration of new technologies, coupled with enhanced techniques and materials, may help everyday clinical practice.

    The central canal of the spinal cord is present at birth and becomes progressively obliterated. Cadaver studies have shown that it may persiste partially or completely. To our knowledge, this entity has not been described on MRI. We reviewed 794 MRI studies of the spinal cord, and found 12 patients (aged 14 to 65 years) who had an intramedullary cavity. The cavity was at the junction of the ventral {sup 1}/{sub 3} and dorsal {sup 2}/{sub 3} of the spinal cord, except at the level of the lumbar enlargement, where it was central. It was filiform in most cases, although sometimes fusiform (3 to 4 mm in diameter), and had regular contours. The cavity were thoracic in 69 % of cases. The clinical features were totally unrelated to the image, and there were no anatomical factors (Chiari malformation, dysraphism) predisposing to syringomyelia. The images were perfectly compatible with a persistent central canal, which we interpret as a variant of normal anatomy. Therefore it is important to regard these findings as normal, to avoid unnecessary treatment and follow-up. (orig.)

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

  11. A background to the feminist movement in Egypt.

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

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

    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.

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

  1. RCRA closure of the Building 3001 Storage Canal

    International Nuclear Information System (INIS)

    The 3001 Storage Canal is located under portions of Buildings 3001 and 3019 at Oak Ridge National Laboratory (ORNL) and has a capacity of approximately 62,000 gallons of water. The term canal has historically been used to identify this structure, however, the canal is an in-ground reinforced concrete structure satisfying the regulatory definition of a tank. From 1943 through 1963, the canal in Building 3001 was designed to be an integral part of the system for handling irradiated fuel from the Oak Ridge Graphite Reactor. Because one of the main initial purposes of the reactor was to produce plutonium for the chemical processing pilot plant in Building 3019, the canal was designed to be the connecting link between the reactor and the pilot plant. During the war years, natural uranium slugs were irradiated in the reactor and then pushed out of the graphite matrix into the system of diversion plates and chutes which directed the fuel into the deep pit of the canal. After shutdown of the reactor, the canal was no longer needed for its designed purpose. Since 1964, the canal has only been used to store radioisotopes and irradiated samples under a water pool for radiation protection. This report describes closure alternatives

  2. The Influence of Canalization on the Robustness of Boolean Networks

    Kadelka, Claus; Laubenbacher, Reinhard

    2016-01-01

    Time- and state-discrete dynamical systems are frequently used to model molecular networks. This paper provides a collection of mathematical and computational tools for the study of robustness in Boolean network models. The focus is on networks governed by $k$-canalizing functions, a recently introduced class of Boolean functions that contains the well-studied class of nested canalizing functions. The activities and sensitivity of a function quantify the impact of input changes on the function output. This paper generalizes the latter concept to $c$-sensitivity and provides formulas for the activities and $c$-sensitivity of general $k$-canalizing functions as well as canalizing functions with more precisely defined structure. A popular measure for the robustness of a network, the Derrida value, can be expressed as a weighted sum of the $c$-sensitivities of the governing canalizing functions, and can also be calculated for a stochastic extension of Boolean networks. These findings provide a computationally eff...

    Full Text Available The objective of the present study is to present a case report of endodontic treatment of a maxillary central incisor with 1 root and 4 root canals. The success of endodontic treatment requires knowledge of dental anatomy and its variations. This clinical article reports an unusual anatomy detected in a maxillary central incisor with 4 root canals with an associated periapical lesion. The incidence of 4 root canals in this tooth is rare. However, it must be taken into consideration, the clinical and radiographic evaluations during the endodontic treatment in order to enhance the diagnostic. Many times, the presence of a supernumerary canal is noticed only after canal treatment due to continuing post-operative discomfort or treatment failure.

    Drying instrumented canals with pressurized air may result in patient morbidity or even fatality. Low pressure and side vent needles have been suggested to lessen the danger. This study observed apical pressures from different needles inserted deeply into small round and ovoid canals as instrumentation progressed. Low-pressure (5 psi) air was injected through the needles, and apical pressures were recorded after each instrument. Pressures varied greatly within each test group. Generalities that can be drawn are that binding the needle within the canal gives higher pressures than with the needle slightly short of binding and that pressures were higher with apexes instrumented to size 30 and higher. With the needle tightly bound, neither needle size, needle design, nor canal shape resulted in statistically significant mean pressure differences. With the needle slightly withdrawn, larger bore needles gave higher pressures than small diameter needles. Caution is advised with the clinical use of pressurized air in the drying of root canals.

    1976-01-01

    As the first major water project in the United States, the old Erie Canal provides an example of the hydrological and environmental consequences of water development. The available record shows that the project aroused environmental fears that the canal might be impaired by the adverse hydrologic effects of land development induced by the canal. Water requirements proved greater than anticipated, and problems of floods and hydraulic inefficiencies beset navigation throughout its history. The Erie Canal proved the practicality of major hydraulic works to the extent that operations and maintenance could cope with the burdens of deficiencies in design. The weight of prior experience that upland streams, such as the Potomac and Mohawk Rivers, had proved unsatisfactory for dependable navigation, led to a decision to build an independent canal which freed the location from the constraints of river channels and made possible a cross-country water route directly to Lake Erie. The decision on dimensioning the canal prism--chiefly width and depth-involved balance between a fear of building too small and thus not achieving the economic potentials, and a fear of building too expensively. The constraints proved effective, and for the first part of its history the revenues collected were sufficient to repay all costs. So great was the economic advantage of the canal that the rising trend in traffic soon induced an enlargement of the canal cross section, based upon a new but riskier objective-build as large as the projected trend in toll revenues would finance. The increased revenues did not materialize. Water supplies were a primary concern for both the planners and the operators of the canal. Water required for lockage, although the most obvious to the planners, proved to be a relatively minor item compared with the amounts of water that were required to compensate for leakage through the bed and banks of the canal. Leakage amounted to about 8 inches of depth per day. The total

    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

    Full Text Available Aims: The aim of this study was to evaluate the reduction of Enterococcus faecalis in curved root canals after various sizes and tapers of the canal preparation. Materials and Methods: Mandibular first molars (n = 103 with curved mesiobuccal canals were divided into one control (n = 5 and 7 experimental (n = 14 groups, were inoculated with E. faecalis (ATTC 29212 and prepared with the following RaCe files (FKG Dentaire as master apical file: Groups: 25.04, 25.06, 30.04, 30.06, 35.04, 35.06 and 40.06. All the experimental groups were irrigated with 2 mL of 1% sodium hypochlorite during instrumentation and finally rinsed with 17% ethylenediaminetetraacetic acid (EDTA (2 mL followed by 5.25% NaOCl (2 mL and sterile distilled water. Colony counting was performed after incubation. Statistical Analysis Used: Resulting data were analyzed using one-way ANOVA and Tukey′s post-hoc test, (P < 0.05. Results and Conclusions: All the experimental groups showed significant bacterial reduction (P < 0.001. Although the greater the size/taper or both led to more decreased amount of bacteria, differences between the groups with the identical size and different tapers, and among the groups with the same taper and different sizes were not significant. Based on this study, 25.04 along with using 2 mL of 1% NaOCl during instrumentation, and using 17% EDTA and 5.25% NaOCl as final rinse successively after the termination of preparation, can effectively reduce intra-canal bacteria and preserve root structure.

    We have designed, built and tested an anthropomorphic-scale surrogate spinal canal, for use in preliminary evaluations of the performance characteristics of a novel intradural spinal cord stimulator. The surrogate employs a silicone mock spinal cord with semi-major and semi-minor diameters of 10 and 6 mm, respectively, commensurate with those of actual thoracic-level spinal cord. The axial restoring force provided by the 300 µm thick silicone denticulate ligament constructs on the mock cord is ~ 0.32 N mm(-1) over a 1.5 mm range of displacement, which is within a factor of 2 of that measured by others in human cadaver specimens. Examples of testing protocols of prototype intradural stimulators that employ this device are discussed. PMID:22953718

    Studies have demonstrated that conventional chemo-mechanical preparation is limited regarding the decontamination of the endodontic space, which is why alternative techniques such as laser radiation have their importance in the modern endodontic treatment. The present study aims to assess the possibility of improving the debridement of the root canals by removing smear layer using Er: YAG laser radiation. We used 18 extracted teeth, which were subjected to the same initial protocol and then divided into 5 study groups: the control group has not been treated with laser; the other 4 groups were exposed to laser radiation using two different geometries peaks of quartz and two energy levels. Scanning electronic microscopy revealed an increased efficiency in the debridement of all interested areas when using PIPS and XPulse tips at proper energy. In the two groups treated with inferior laser energy, the debridement didn't prove to be superior to the conventional treatment.

  20. MANAGEMENT OF LUMBAR SPINAL CANAL STENOSIS

    Directory of Open Access Journals (Sweden)

    Mukhergee G. S

    2016-06-01

    Full Text Available BACKGROUND Spinal stenosis is one of the most common conditions in the elderly. It is defined as a narrowing of the spinal canal. The term stenosis is derived from the Greek word for narrow, which is “Stenos”. The first description of this condition is attributed to Antoine portal in 1803. Verbiest is credited with coining the term spinal stenosis and the associated narrowing of the spinal canal as its potential cause. [1-10] Kirkaldy–Willis subsequently described the degenerative cascade in the lumbar spine as the cause for the altered anatomy and pathophysiology in spinal stenosis. [11-15] If compression does not occur, the canal should be described as narrow but not stenotic. Some studies defined lumbar spinal stenosis as a “narrowing of the osteoligamentous vertebral canal and/or the intervertebral foramina causing compression of the thecal sac and/or the caudal nerve roots; at a single vertebral level, narrowing may affect the whole canal or part of it” (Postacchini 1983. This definition distinguished between disc herniation and stenosis. [16] . The most common type of spinal stenosis is caused by degenerative arthritis of the spine. Hypertrophy and ossification of the posterior longitudinal ligament which usually are confined to the cervical spine, and diffuse idiopathic skeletal hyperostosis (DISH syndrome also may result in an acquired form of spinal stenosis. Congenital forms caused by disorders such as achondroplasia and dysplastic spondylolisthesis are much less common. Congenital spinal stenosis usually is central and is evident or imaging studies. Idiopathic congenital narrowing usually involves the anteroposterior dimension of the canal secondary to short pedicles; the patient otherwise is normal. In contrast, in achondroplasia, the canal is narrowed in the anteroposterior plane owing to shortened pedicles and in lateral dimension because of diminished interpedicular distance. Acquired forms of spinal stenosis usually are

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

    1979-04-01

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

    Complications that arise during endodontic procedures pose serious threats to the long-term integrity and health of the tooth. Potential complexities of root canals include residual pulpal tissue, cracks, mesial-buccal 2 and accessory canals. In the case of a failed root canal, a successful apicoectomy can be jeopardized by isthmuses, accessory canals, and root microfracture. Confirming diagnosis using a small imaging probe would allow proper treatment and prevent retreatment of endodontic procedures. An ultrathin and flexible laser scanning endoscope of 1.2 to 1.6mm outer diameter was used in vitro to image extracted teeth with varied root configurations. Teeth were opened using a conventional bur and high speed drill. Imaging within the opened access cavity clarified the location of the roots where canal filing would initiate. Although radiographs are commonly used to determine the root canal size, position, and shape, the limited 2D image perspective leaves ambiguity that could be clarified if used in conjunction with a direct visual imaging tool. Direct visualization may avoid difficulties in locating the root canal and reduce the number of radiographs needed. A transillumination imaging device with the separated illumination and light collection functions rendered cracks visible in the prepared teeth that were otherwise indiscernible using reflected visible light. Our work demonstrates that a small diameter endoscope with high spatial resolution may significantly increase the efficiency and success of endodontic procedures.

    Full Text Available Aim: To examine facial canal status in patients with chronic otitis media (COM surgery and to detect the relation between facial canals dehiscence (FCD with middle ear pathology in these patients. Material and Method: The surgery data of patients who were subjected to tympanoplasty with or without mastoidectomy and radical mastoidectomy due to COM were analyzed retrospectively from January 2006 to December 2012. In addition to demonstrative data of the patients, status of facial canal and preoperative diagnoses of patients, type of the operation performed, status of middle ear, number of surgeries, existence of cholesteatoma, existence of ossicular chain defect, lateral canal defect and dura defect were assessed and the relation thereof with facial canal dehiscence (FCD was analyzed statistically. Results: Seven hundred ninety six patients were included in the study. FCD was detected in 10.05% of the patients. FCD was most frequently observed in the tympanic segment. It was found out that there was a statistically significant relationship of middle ear pathology, cholesteatoma, revision surgery, lateral semicircular canal and ossicular chain defect with FCD. Discussion: COM diagnosed patients may have defect in facial canal according to their preoperative diagnoses, middle ear pathologies, number of operations and ossicular chain defects. These patients should be applied a more careful surgery and closely followed up in postoperative periods.

    Full Text Available This study applies a new method and technology to measure the discharge in a lined canal in Taiwan. An Acoustic Digital Current Meter mounted on a measurement platform is used to measure the velocities over the full cross-section for establishing the measurement method. The proposed method primarily employs Chiu’s Equation which is based on entropy to establish a constant ratio the relation between the maximum and mean velocities in an irrigation canal, and compute the maximum velocity by the observed velocity profile. In consequence, the mean velocity of the lined canal can be rapidly determined by the maximum velocity and the constant ratio. The cross-sectional area of the artificial irrigation canal can be calculated for the water stage. Finally, the discharge in the lined canal can be efficiently determined by the estimated mean velocity and the cross-sectional area. Using the data of discharges and stages collected in the Wan-Dan Canal, the correlation of stage and discharge is also developed for remote real-time monitoring and estimating discharge from the pumping station. Overall, Chiu’s Equation is demonstrated to reliably and accurately measure discharge in a lined canal, and can serve as reference for future calibration for a stage-discharge rating curve.

    The purpose of this study was to compare the bacterial leakage of root canals obturated with three root canal sealers, using Endodontalis faecalis as a microbial tracer to determine the length of time for bacteria to penetrate through the obturated root canal to the root apex. Seventy-five, single-rooted teeth with straight root canals had the crown cut off at the cementoenamel junction. Root canals were instrumented by a step-back technique. The prepared teeth were randomly divided into 3 groups of 19 teeth each and another 2 groups as positive and negative controls (9 teeth each). The experimental groups were dependent on the sealer used: AH-Plus, Apexit, and Ketac-Endo. The root canals were obturated using a lateral condensation technique. After 24 h the teeth were attached to microcentrifuge tubes with 2 mm of the root apex submerged in Brain Heart Infusion broth in glass test tubes. The coronal portions of the root canal filling materials were placed in contact with E. faecalis. The teeth were observed for bacterial leakage daily for 30 and 60 days. With the chi2 test for comparing pairs of groups at the 0.05 level (p 0.06), but Apexit had significantly higher leakage (p 0.05), but Apexit leaked more than AH-Plus. The conclusion drawn from this experiment was that epoxy resin root canal sealer was found to be more adaptable to the root canal wall and filling material than a calcium hydroxide sealer when bacterial coronal leakage was studied.

    Cytogenetic analyses were performed on peripheral blood from 46 present or past residents of the area surrounding Love Canal, a former dump site for chemical wastes in Niagara Falls, NY. Participants included 17 persons in whom cytogenetic analyses had been performed in 1980 and 29 persons who had been living in 1978 in seven homes that directly adjoined the canal and in which environmental tests showed elevated levels of chemicals spreading from the canal. Frequencies of chromosomal aberrations and of sister chromatid exchange (SCE) did not differ significantly from control levels. For all participants, cigarette smoking was associated with an increase in sister chromatid exchange frequency.

    The success rate of root canal therapy(RCT)have been improved continuously along with the advancement in RCT techniques in the past several decades. If standard procedures of modern RCT techniques are strictly followed, the success rate of RCT may exceed 90%. The success of RCT is mainly affected by such factors as clear concept of the anatomy of root canals, proper mechanical and chemical preparation and perfect filling of root canal system. If these factors are sufficiently noted, a success is easy to achieve. Even though the primary RCT fails, retreatment can further be conducted to save the diseased teeth. PMID:27511032
