  1. Abu Dhabi: prudence in the future

    Energy Technology Data Exchange (ETDEWEB)

    Abu Dhabi is the largest oil producer of the 7 United Arab Emirates. The government is strictly controlling the production rate and has lowered it by 110,000 bpd to 740,000 bpd. Even further cuts have been ordered recently. Reserves are estimated at 50 times present production rate, but may be overestimated. Efforts are being made in the areas of offshore exploration and secondary recovery. There is only one refinery, and even domestic needs require refinery expansion. A new refinery of 120,000 bpd capacity is under construction at Ruweis. Most of the production is exported to Japan, followed by the US, France, the Netherlands and Dutch Indies. The most interesting field is Zakum, the full development of which may cost $4 billion.

    The ancient oasis-city of Al Ain in Abu Dhabi Emirate still retains the most important and outstanding cultural heritage of United Arab Emirates (UAE). The larger area of Abu Dhabi Emirate comprised of archaeological sites, cultural landscapes and historic buildings dating back to 3rd millennium to the recent pre-oil era. Traditional materials like stone, earth and palm wood were used in combination with local construction methods. For the last seven years the newly formed Abu Dhabi Tourism & Culture Authority (TCA Abu Dhabi)1 has been actively involved in conservation of built heritage in Abu Dhabi Emirate with the help of its Conservation Section. Documentation prior to any conservation and restoration works is considered as a basic pre-requisite for understanding an historic building or site. It is a process which continues during the conservation of any monument and is the only accurate tool for recording information in order to understand the structure, ultimately leading to the management of cultural heritage. Application and use of tools, ranging from basic manual techniques to 3D laser scanning, based on the best practices and international guidelines the exercise will help in establishing a documentation lab with standard procedures, specifications and tools for the documentation and monitoring the built heritage of Abu Dhabi Emirate. This paper will discuss a range of case studies and will demonstrate how documentation and monitoring of the built heritage has augmented the various conservation initiatives on a variety of building types.

  3. Middle East gas export projects: The case of Abu Dhabi

    International Nuclear Information System (INIS)

    Abu Dhabi is ranked in the industry journals in the top 5 in the world tables of both oil and gas reserves. Gas is produced both Onshore and Offshore from associated and non-associated fields. Production has tripped during the last ten years and will increase further in the next few years as a result of current and planned investment. Development of Abu Dhabi's gas resources is aimed at enhancing oil production and recovery, meeting local and export demand and eliminating waste. Companies in Abu Dhabi are involved in all the main sectors of gas industry including production, processing, transportation and sales. The first large LNG export project by sea in Arabian Gulf was established in 1977 from Abu to Japan. Development continues and the gas is exported as LNG and is also processed into LPG and Pentane Plus for export. Japan remains the main market. The volume of Condensate available for export and processing will increase significantly in the next few years. In order to ensure a continuing and increasing supply of gas to world markets, in future years, prices will need to provide an adequate return on investment and should also reflect the environmental advantages of gas. 9 tabs

    The vertical profiles of ozone are measured coincidently with non-methane volatile organic compounds (NMVOCs) at the meteorological site located at the Abu Dhabi international airport (latitude 24.45N; longitude 54.22E) during the years 2012 - 2014. Some of the profiles show elevated surface ozone >95 ppbv during the winter months (December, January and February). The ground-level NMVOCs obtained from the gas chromatography-flame ionization detection/mass spectrometry system also show elevated values of acetylene, ethane, propane, butane, pentane, benzene, and toluene. NMVOCs and ozone abundances in other seasons are much lower than the values in winter season. NMVOCs are emitted from an extensive number of sources in urban environments including fuel production, distribution, and consumption, and serve as precursor of ozone. Transport sources contribute a substantial portion of the NMVOC burden to the urban atmosphere in developed regions. Abu Dhabi is located at the edge of the Arabian Gulf and is highly affected by emissions from petrochemical industries in the neighboring Gulf region. The preliminary results indicate that wintertime enhancement in ozone is associated with large values of NMVOCs at Abu Dhabi. The domestic production of surface ozone is estimated from the combination of oxygen recombination and NMVOCs and compared with the data. It is estimated that about 40-50% of ozone in Abu Dhabi is transported from the neighbouring petrochemical industries. We will present ozone sounding and NMVOCs data and our model estimates of surface ozone, including a discussion on the high levels of the tropospheric ozone responsible for contaminating the air quality in the UAE.

  5. Geomorphological evolution of the dynamic Abu Dhabi coastline

    The Abu Dhabi coastline provides an ideal setting for studying sedimentation processes in an arid depositional environment directly analogous to that of many of the region's Mesozoic petroleum reservoirs. This coastline displays a low-angle ramp geometry with supratidal evaporite precipitation passing offshore, through a broad carbonate-evaporite intertidal setting with complex depositional facies geometries, into a subtidal carbonate depositional environment. The coast is locally protected from open marine conditions by a number of peninsulas and offshore shoals and islands associated with the east-west trending Great Pearl Bank. This offers an ideal setting for studying the effects of relative sea-level fluctuations on sedimentary systems and shoreline morphology. A late Holocene progradation rate of 0.75 m/yr has previously been established for the Abu Dhabi Sabkha system (Lokier and Steuber, 2008) however we conjecture that the system has now entered a broadly retrogradational phase. By applying current estimates of global sea level rise of 3.3 mm/yr derived from satellite altimetry and tide gauges (Cazenave and Nerem, 2004; Leuliette et al., 2004), we calculate present day marine transgression of the Abu Dhabi shoreline at a rate of 8.25 m/yr. This study utilised 7 years of fieldwork observations and satellite imagery to establish numerous lines of evidence for active retrogradation over an area of Abu Dhabi coastline lying between Al Dabb'iya in the east and Abu al Abyad in the west. The landward advance of spits and beach ridge systems was monitored at several locations with rates of retrogradation of up to 28 m per year being recorded in some instances. These are significantly greater than those predicted from sea-level rise and may indicate a local subsidence. The landward and seaward limits of microbial mat belts are strongly controlled by their location in the intertidal zone. The seaward side of the Recent microbial mat belt in the Abu Dhabi Sabkha is

    Full Text Available Las demandas presentadas por el Jeque Shakhbout en 1959 para obtener la plena soberanía jurídica sobre el emirato de Abu Dhabi generaron una crisis diplomática plasmada en la correspondencia interna del gobierno Británico. Con sus demandas, el Jeque Shakhbout forzaba a la burocracia a cargo de los Estados de la Tregua – La Oficina de Asuntos Extranjeros en Londres, el representante del gobierno Británico en Bahreín, y los agente administrativos y políticos en Dubai y Abu Dhabi a reexaminar las bases legales de la presencia Británica en la zona y los límites éticos del sistema judicial impuesto sobre sus habitantes. La crisis va mas allá de una discusión sobre los poderes jurisdiccionales. La crisis nos ofrece una ventana a las contradicciones inherentes a la  presencia Británica en la zona, en el marco del movimiento nacionalista árabe y del desarrollo de la industria petrolera y la futura redefinición de la relación entre Abu Dhabi  y la Gran Bretaña.Palabras clave: Abu Dhabi, Gran Bretaña, colonialismo___________________________Abstract:Demands to the British government for supreme jurisdiction over his territory presented by the ruler of Abu Dhabi in 1959 created a diplomatic crisis captured in the internal correspondence of the British government. Sheikh Shakhbout forced the entire bureaucracy that was dealing with the Trucial States – the Foreign Office in London, the British Resident in Bahrain, and the Political and Administrative Agents in Abu Dhabi and Dubai – to reexamine the legality of their presence in the region and the ethical limits of the judicial system imposed on this land.The crisis went beyond the mere discussion over jurisdictional powers. It is also a window into the contradictions linked to the British presence in the region, within the framework of the nascent Arab Nationalist movement and the development of the oil industry . All of which will soon change the nature of the relationship between

    2016-04-01

    Mobile LiDAR system provides a new technology which can be used to update geospatial information by direct and rapid data collection. This technology is faster than the traditional survey ways and has lower cost. Abu Dhabi Municipal System aims to update its geospatial system frequently as the government entities have invested heavily in GIS technology and geospatial data to meet the repaid growth in the infrastructure and construction projects in recent years. The Emirate of Abu Dhabi has witnessed a huge growth in infrastructure and construction projects in recent years. Therefore, it is necessary to develop and update its basemap system frequently to meet their own organizational needs. Currently, the traditional ways are used to update basemap system such as human surveyors, GPS receivers and controller (GPS assigned computer). Then the surveyed data are downloaded, edited and reviewed manually before it is merged to the basemap system. Traditional surveying ways may not be applicable in some conditions such as; bad weather, difficult topographic area and boundary area. This paper presents a proposed methodology which uses the Mobile LiDAR system to update basemap in Abu Dhabi by using daily transactions services. It aims to use and integrate the mobile LiDAR technology into the municipality's daily workflow such that it becomes the new standard cost efficiency operating procedure for updating the base-map in Abu Dhabi Municipal System. On another note, the paper will demonstrate the results of the innovated workflow for the base-map update using the mobile LiDAR point cloud and few processing algorithms.

    2014-07-01

    The subsurface geology of Abu Dhabi in the United Arab Emirates is primarily composed of carbonate rocks. Such media are known to be highly heterogeneous. Very few studies have attempted to estimate attenuation in carbonate rocks. In Abu Dhabi no attenuation profile has been published. This study provides the first seismic wave attenuation profiles in Abu Dhabi using dense array of VSP data. We estimated three attenuation profiles: the apparent, the scattering, and the intrinsic attenuations. The apparent attenuation profile was computed using amplitude decay and spectral-ratio methods. The scattering attenuation profile was estimated using a generalized reflection-transmission matrix forward model. It is usually estimated from the sonic log, but to be more consistent with the apparent attenuation, we succeeded in this paper to estimate it from the VSP data. We subtracted the scattering attenuation from the apparent attenuation to deduce the intrinsic attenuation. The results of the study indicate that the scattering attenuation is significant compared to the published studies that are mainly based on clastic rocks. The high scattering attenuation can reach up to 0.02. It can be explained by the strong heterogeneity of the carbonate rocks. This study demonstrates that the Simsima and Rus Formations have considerable scattering and intrinsic attenuations. These formations are considered aquifers in Abu Dhabi; we therefore interpreted this high intrinsic attenuation zones to be due to the heterogeneity and to the fluids contained in these formations. The Umm-Er-Radhuma Formation is a more homogenous formation with limited aquifer potential. Hence, scattering and intrinsic attenuations of the Umm-Er-Radhuma Formation are low.

    Seismic wave attenuation is a promising attribute for the petroleum exploration, thanks to its high sensitivity to physical properties of subsurface. It can be used to enhance the seismic imaging and improve the geophysical interpretation which is crucial for reservoir characterization. However getting an accurate attenuation profile is not an easy task, this is due to complex mechanism of this parameter, although that many studies were carried out to understand it. The degree of difficulty increases for the media composed of carbonate rocks, known to be highly heterogeneous and with complex lithology. That is why few attenuation studies were done successfully in carbonate rocks. The main objectives of this study are, Getting an accurate and high resolution attenuation profiles from several oil fields. The resolution is very important target for us, because many reservoirs in Abu Dhabi oil fields are tight.Separation between different modes of wave attenuation (scattering and intrinsic attenuations).Correlation between the attenuation profiles and other logs (Porosity, resistivity, oil saturation…), in order to establish a relationship which can be used to detect the reservoir properties from the attenuation profiles.Comparison of attenuation estimated from VSP and sonic waveforms. Provide spatial distribution of attenuation in Abu Dhabi oil fields.To reach these objectives we implemented a robust processing flow and new methodology to estimate the attenuation from the downgoing waves of the compressional VSP data and waveforms acquired from several wells drilled in Abu Dhabi. The subsurface geology of this area is primarily composed of carbonate rocks and it is known to be highly fractured which complicates more the situation, then we separated successfully the intrinsic attenuation from the scattering. The results show that the scattering is significant and cannot be ignored. We found also a very interesting correlation between the attenuation profiles and the

    The United Arab Emirates (UAE) government has declared the increased use of alternative energy a strategic goal and has invested in identifying and developing various sources of such energy. This study aimed at assessing the viability of establishing wind farms offshore the Emirate of Abu Dhabi, UAE and to identify favourable sites for such farms using Geographic Information Systems (GIS) procedures and algorithms. Based on previous studies and on local requirements, a set of suitability criteria was developed including ocean currents, reserved areas, seabed topography, and wind speed. GIS layers were created and a weighted overlay GIS model based on the above mentioned criteria was built to identify suitable sites for hosting a new offshore wind energy farm. Results showed that most of Abu Dhabi offshore areas were unsuitable, largely due to the presence of restricted zones (marine protected areas, oil extraction platforms and oil pipelines in particular). However, some suitable sites could be identified, especially around Delma Island and North of Jabal Barakah in the Western Region. The environmental impact of potential wind farm locations and associated cables on the marine ecology was examined to ensure minimal disturbance to marine life. Further research is needed to specify wind mills characteristics that suit the study area especially with the presence of heavy traffic due to many oil production and shipping activities in the Arabian Gulf most of the year.

    Abu Dhabi Government endorsed vision for its Maritime Strategy `A safe, secure and sustainable maritime domain for Abu Dhabi'. This research study share this vision using the concept of monitoring as tool for marine protection against any possible oil pollution. The best technology to detect and monitor oil pollution and in particularly oil spill is SAR imagery In this case study we chose KOMPSAT-5 SAR. KOMPSAT-5 carries X-band SAR for earth observation, and is capable of day-and-night imaging under all weather condition. It provides three operation modes: High Resolution Mode to provide 1 m resolution, Standard Mode to provide 3 m resolution and Wide Swath Mode to provide 20 m resolution with 100 km swath at 550 km altitude, with four modes of polarization. KOMPSAT-5 provides products for various applications; security and defense, mapping, and natural resource management, environmental monitoring, disaster monitoring and more. For our case study we chose to work with Wide Swath mode (WS) with Vertical polarization (VV) to cover a wide area of interest located to the north west of Abu Dhabi including some important islands like "Zirku Island", and areas with oil production activities. The results of data acquired on 4th May 2015 show some spot of oil spill with length estimated about 3 KM, and the daily satellite data acquisition over the period July 24 through July 31 shows serious and many oil spill events some are small, but many others are considered to be big with area size around 20 km2. In the context of oil spill pollution in the seas, we have to consider the development and increase of overseas transportation, which is an important factor for both social and economic sectors. The harmful effects of marine pollution are numerous, from the damage of marine life to the damage of the aquatic ecosystem as whole. As such, the need for oil slick detection is crucial, for the location of polluted areas and to evaluate slick drift to protect the coastline

Substantial landings of elasmobranchs, usually as gillnet by-catch, were recorded in Kuwait, Qatar and the Emirate of Abu Dhabi (part of the United Arab Emirates), although larger elasmobranchs from targeted line fisheries were landed in Abu Dhabi. The elasmobranch fauna recorded was distinctive and included species that are undescribed, rare and have a highly restricted known distribution. Numerical abundance was dominated by sharks (c. 80%), of which carcharhinids were by far the most important. The milk shark Rhizoprionodon acutus and whitecheek shark Carcharhinus dussumieri together comprised just under half of all recorded individuals. Around 90% of recorded sharks were small (50-90 cm total length, L(T) ) individuals, most of which were mature individuals of species with a small maximum size (Qatar currently report zero or no elasmobranch landings to the FAO.

    In January 2013, several months after Middle East respiratory syndrome coronavirus (MERS-CoV) was first identified in Saudi Arabia, Abu Dhabi, United Arab Emirates, began surveillance for MERS-CoV. We analyzed medical chart and laboratory data collected by the Health Authority–Abu Dhabi during January 2013–May 2014. Using real-time reverse transcription PCR, we tested respiratory tract samples for MERS-CoV and identified 65 case-patients. Of these patients, 23 (35%) were asymptomatic at the time of testing, and 4 (6%) showed positive test results for >3 weeks (1 had severe symptoms and 3 had mild symptoms). We also identified 6 clusters of MERS-CoV cases. This report highlights the potential for virus shedding by mildly ill and asymptomatic case-patients. These findings will be useful for MERS-CoV management and infection prevention strategies. PMID:27314227

    Rapid population increase coupled with urbanization and industrialization has resulted in shortages of water in the Middle East. This situation is further exacerbated by global climate change due to greenhouse gas emissions. Recent research advocates that solutions to the global water security and scarcity crisis must involve water–energy nexus approaches. This means adopting policies and strategies that harmonize these inter-related sectors to minimize environmental impact while maximizing human benefit. In the case of Abu Dhabi, when designing and locating oil/gas refineries and associated power generation facilities, previous relevant decisions were based on simple economic and geographical grounds, such as nearness to oil rigs, pipelines, existing industries and port facilities, etc. The subsequent design and location of water abstraction and treatment works operated by the waste heat from these refining and/or power generation processes was catered for as an afterthought, meaning that there is now a mismatch between the water and energy supplies and demands. This review study was carried out to show how Abu Dhabi is trying now to integrate its water–energy sectors using a nexus approach so that future water/power infrastructure is designed optimally and operated in harmony, especially in regard to future demand. Based upon this review work, some recommendations are made for designers and policy makers alike to bolster the nexus approach that Abu Dhabi is pursuing. PMID:27023583

    The distribution of benthic foraminifera and sedimentary facies from Recent coastline environments adjacent to the coastline of Abu Dhabi (UAE) was studied in detail with the aim to: 1) provide reliable analogs for understanding and interpreting the depositional environment of ancient shallow-marine sediments from the UAE; 2) assess any modifications in the distribution of benthic environments and sedimentary facies in an area affected by significant anthropogenic activities - particular construction and land reclamation. A total of 100 sea-floor sediment samples were collected in different shallow-marine sedimentary environments (nearshore shelf, beach-front, channels, ooid shoals, lagoon and mangals) close to the coastline of Abu Dhabi Island. Where possible, we revisited the sampling sites used in several studies conducted in the middle of last century (prior to any significant anthropogenic activities) to assess temporal changes in Recent benthic foraminifera and sedimentary facies distribution during the last 50 years. Five foraminiferal assemblages were recognized in the studied area. Species with a porcellaneous test mainly belonging to the genera Quinqueloculina, Triloculina, Spiroloculina, Sigmoilinita are common in all studied areas. Larger benthic foraminifera Peneroplis and Spirolina are particularly abundant in samples collected on seaweed. Hyaline foraminifera mostly belonging to the genera Elphidium, Ammonia, Bolivina and Rosalina are also common together with Miliolidae in the nearshore shelf and beach front. Agglutinated foraminifera (Clavulina, Textularia, Ammobaculites and Reophax) are present in low percentages. The species belonging to the genera Ammobaculites and Reophax are present only in the finest grain samples particularly in lagoons and mangal environments and have not been reported previously in the studied area. The majority of the ooid shoal sediments, the coarser sediments of the beach-front and samples collected in dredged channels

    Velocity data from uphole surveys were used to map the water table and the contact at the base dune sand/top alluvium as part of a joint National Drilling Company-United States Geological Survey Ground Water Research Project in the Emirate of Abu Dhabi. During 1981-1983, a reconnaissance seismic survey was conducted for petroleum exploration in the eastern region of Abu Dhabi. Approximately 2800 kilometers of seismic data, consisting of 92 lines, were acquired in the 2500 km2 concession area near Al Ain. Uphole surveys were conducted about 2 km apart along each seismic line, and were used to calculate weathering corrections required to further process in the seismic data. Approximately 1300 uphole surveys were completed in the concession area between March 1981 and June 1983. Reinterpretation of the velocity profiles derived from the uphole surveys provided data for determining the following subsurface layers, listed in descending order: (1) a surficial, unconsolidated weathering layer with a velocity from 300 to 450 m/s; (2) surficial dune sand, from 750 to 900 m/s; (3) unsaturated, unconsolidated alluvium, from 1000 to 1300 m/s; and (4) saturated, unconsolidated alluvium, from 1900 to 2200 m/s. Two interfaces-the water table and the base dune sand/top alluvium - were identified and mapped from boundaries between these velocity layers. Although the regional water table can fluctuate naturally as much as 3 m per year in this area and the water-table determinations from the uphole data span a 27-month period, an extremely consistent and interpretable water-table map was derived from the uphole data throughout the entire concession area. In the northern part of the area, unconfined groundwater moves northward and northwestward toward the Arabian Gulf; and in the central and southern parts of the area, groundwater moves westward away from the Oman Mountains. In the extreme southern area east of Jabal Hafit, groundwater moves southward into Oman. The map of the base

    Full Text Available The present study was designed to determine the prevalence of different types of mastitis in camels in U.A.E. and to identify the causative microorganisms and their sensitivity to different antimicrobial agents. From 162 lactating she-camels, 630 milk samples were collected from different cities in Abu Dhabi Emirate/UAE. The overall prevalence of mastitis was 18.52% (7.94% on quarter basis, the prevalence of clinical and sub clinical mastitis was found to be 24.70% and 11.67% on animal basis, respectively; it being 9.70% and 5.86% on quarter basis, respectively. The hind quarters were more frequently affected than the fore quarters. Bacteriological examination of milk samples revealed that Staphylococcus was the chief etiological agents both in clinical and sub clinical mastitis (41.67% in camels, followed by Streptococcus spp. (21.67%, Enterobacter spp. (15.00%, C. pyogenes (10.00%, Micrococcus spp. (5.00%, Pasteurells spp. (5.00% and Pseudomonas aeruginosa (1.66%. Most of the Staphylococcus spp., Streptococcus spp. and C. pyogenes strains were sensitive to carbenicillin, gentamycin, kanamycin, and erythromycin, but resistant to colistin and sulphamethoxazole. Other pathogens like Enterobacter, Micrococcus, Pasteurella spp. and Ps. aeuroginosa isolates showed variable sensitivities to the antimicrobials.

    The Abu Dhabi Authority for Culture and Heritage (ADACH) is responsible for the conservation and management of historic buildings and archaeological sites in the Emirate. Laboratory analysis has been critical for understanding the composition of historic materials and establishing appropriate conservation treatments across a wide variety of building types, ranging from Iron Age earthen archaeological sites to late-Islamic stone buildings. Analysis was carried out on historic sites in Al Ain, Delma Island and Liwa Oasis using techniques such as micro-x-ray fluorescence (MXRF), scanning electron microscopy/energy dispersive x-ray spectroscopy (SEM-EDX), polarized light microscopy (PLM), and x-ray diffraction (XRD). Testing was conducted through consultant laboratories and in collaboration with local universities. The initial aim of the analysis was to understand historic earthen materials and to confirm the suitability of locally sourced clays for the production of mud bricks and plasters. Another important goal was to characterize materials used in historic stone buildings in order to develop repair mortars, renders and grouts.

  16. Hydrology of the coastal sabkhas of Abu Dhabi, United Arab Emirates

    2001-05-01

    Water fluxes were estimated and a water budget developed for the land surface and a surficial 10-m-deep section of the coastal sabkhas that extend from the city of Abu Dhabi, United Arab Emirates, west to the border with Saudi Arabia. The fluxes were estimated on the basis of water levels and hydraulic conductivities measured in wells and evaporation rates measured with a humidity chamber. In contrast with conceptual models proposed in earlier studies, groundwater inflow is estimated to be small, whereas the largest components of the water budget are recharge from rainfall and evaporation from the water table. Estimates within a rectilinear volume of sabkha, defined as 1 m wide by 10 km long by 10 m deep, indicate that about 1 m3/year of water enters and exits by lateral groundwater flow; 40-50 m3/year enters by upward leakage; and 640 m3/year enters by recharge from rainfall. Based on the water and solute fluxes estimated for the upward leakage into the sabkha, 7-8 pore volumes of brine have entered the sabkha from below since the time the sabkha became saturated (7,000 years ago) as a result of the last global sea-level rise. Résumé. Les flux d'eau ont été estimés et le bilan hydrique a été réalisé pour la surface et les dix premiers mètres sous la surface de sebkhas littorales qui s'étendent à partir de la ville d'Abou Dhabi (Émirats Arabes Unis) à l'ouest de la frontière avec l'Arabie Saoudite. Les flux ont été estimés à partir des niveaux piézométriques et des conductivités hydrauliques mesurés dans les puits et à partir de mesures d'évaporation au moyen de capteurs d'humidité. En opposition avec les modèles conceptuels proposés dans les premières études, on estime que les apports par les eaux souterraines sont faibles, alors que les termes du bilan hydrique les plus importants sont la recharge par la pluie et l'évaporation à partir de la nappe.

    This paper describes how geochemical data (Rock Eval analysis, SARA composition) combined with wireline log interpretation allows for the recognition of the distribution and continuity of bitumens in a main reservoir of an offshore giant field in Abu Dhabi. The integration of new geochemical data with data and field information provided by the oil company ZADCO allows for the recognition of two types of bitumen rich levels in the main reservoir of the field: (a) one corresponding to bitumen rich main reservoir intervals associated with high resistivity and high oil saturation, these intervals can be called 'tar mats', (b) the other corresponding to low oil saturated intervals, and can be classified as 'heavy residual oil'. In terms of lateral and vertical distribution, the tar mats are found at the crestal area of the Present-day structure and are located at the base of the reservoir unit above a tight limestone which plays a role of being a vertical permeability barrier. The tar mats seem to be independent of the Present-day OWC and are not related to biodegradation processes. The heavy residual oil is mainly located in the Northeast and the Southeast parts of the field and close to the OWC but it is also present all around the field except (1) in the west, in the area of the spill point and (2) in the Northwest area where direct contact between mobile oil and water is detected. Study of the structural evolution demonstrates that a tilting of the field began at Dammam age time (Eocene). The tilting of the structure led to a reduction of the structural closure in the West followed by the leakage of part of the originally trapped oil. Numerical modeling of such a geological scenario leads to a distribution of fluids (water, movable oil and residual oil) very close to the one observed at Present-day time in the field. This modeling allows a prediction of the extension and distribution of the residual heavy oil within the studied reservoir and can

    More than half a century ago, the Abu Dhabi coastline was subject to intensive research efforts by institutions from all over the world. This activity was mostly related to the onset of oil exploration in the region and the hypothesis that the modern Abu Dhabi Sabkha provides a direct analogue to the ancient deposits of the hydrocarbon-bearing Arab Formation. While research initially concentrated on a characterisation of the bulk depositional system, focus has recently shifted to answer more specific questions such as the role of microbial mats in the formation of dolomite. Through this shift to a smaller scale, the remainder of the sabkha, including its microbial mats, was neglected and little further activity was undertaken to characterise the coastal sabkha using modern, state-of-the-art, research tools and methods. This paper will not attempt to reinvent the wheel with respect to the work of the early researchers; we will instead present an updated model of the sedimentary system of the coastal sabkha of Abu Dhabi. This model will focus on establishing the relationship and controlling factors between primary deposits of the carbonate ramp system and secondary early diagenetic precipitates. Initial results show that primary deposits of the UAE's carbonate ramp are equivalent to carbonate mudstones, packstones, grainstones, and occasional rudstones with a packstone matrix, that form above a Holocene to Recent hardground. These deposits occur mostly in a subtidal to lower intertidal setting, landward of which they are gradually being covered by a green cyanobacterial layer that binds the primarily unconsolidated sediment. Further landward, in the middle and upper intertidal zones, these cyanobacterial layers grade into more complex microbial mat layers of potentially highly diverse bacterial and algal faunal composition. Microbial mat layers in the upper intertidal and the lower supratidal zones are increasingly interspersed with gypsum crystals and white

    Zonation of Recent mangrove environments can be defined using benthic foraminifera, however, little is known about foraminifera from mangrove environments of the Arabian Gulf. The objective of this study is to produce a detailed micropaleontological and sedimentological analysis to identify foraminiferal associations in several coastline environments (mangrove swamps and channels) located on the eastern side of Abu Dhabi Island (UAE). Detailed sediment sampling collection in mangal environments of Eastern Abu Dhabi was carried out to assess the distribution of living and dead benthic foraminifera in different sedimentary facies in the mangal and in the surrounding area comprising natural environments of the upper and lower intertidal area (mud flats and channels) and areas modified by anthropogenic activities (dredged channels). The fine-grain sediments collected near mangrove (Avicenna marina) roots presented a high abundance of living and dead foraminifera tests. The assemblages in these samples show very low diversity and are almost entirely constituted of small-sized opportunistic species belonging to the genera Ammonia and Elphidium. In particular: • Samples collected on the mud flat and in ponds at the margin of the channel show a foraminiferal assemblage characterised by abundant foraminifera belonging to the genera Ammonia, Elphidium, Triloculina, Quinqueloculina, Peneroplis and Spirolina. • Samples collected in the lower (wet) intertidal area close to Avicenna marina roots, presented a low-diversity assemblage mostly comprising opportunistic foraminifera of the genera Ammonia and Elphidium along with rare miliolidae. • Samples from the upper intertidal area (dry) close to Avicenna marina roots, produced an assemblage exclusively composed of small-sized opportunistic Ammonia and Elphidium, together with abundant specimens belonging to the genera Trochammina. Throchammina specimens have not been previously recorded from Recent sedimentary samples of

    2007-01-01

    A solute mass-balance study of ground water of the 3000 km2 coastal sabkhat (salt flats) of the Emirate of Abu Dhabi, United Arab Emirates, documents an annual bromide loss of approximately 255 metric tons (0.0032 Gmoles), or 85 kg/km2. This value is an order of magnitude greater than previously published direct measurements from the atmosphere over an evaporative environment of a salar in Bolivia. Laboratory evidence, consistent with published reports, suggests that this loss is by vapor transport to the atmosphere. If this bromine flux to the atmosphere is representative of the total earth area of active salt flats then it is a significant, and generally under recognized, input to the global atmospheric bromide flux.

  1. Structure, Aboveground Biomass, and Soil Characterization of Avicennia marina in Eastern Mangrove Lagoon National Park, Abu Dhabi

    Alsumaiti, Tareefa Saad Sultan

    Mangrove forests are national treasures of the United Arab Emirates (UAE) and other arid countries with limited forested areas. Mangroves form a crucial part of the coastal ecosystem and provide numerous benefits to society, economy, and especially the environment. Mangrove trees, specifically Avicennia marina, are studied in their native habitat in order to characterize their population structure, aboveground biomass, and soil properties. This study focused on Eastern Mangrove Lagoon National Park in Abu Dhabi, which was the first mangrove protected area to be designated in UAE. In situ measurements were collected to estimate Avicennia marina status, mortality rate (%), height (m), crown spread (m), stem number, diameter at breast height (cm), basal area (m), and aboveground biomass (t ha-1 ). Small-footprint aerial light detection and ranging (LIDAR) data acquired by UAE were processed to characterize mangrove canopy height and aboveground biomass density. This included extraction of LIDAR-derived height percentile statistics, segmentation of the forest into structurally homogenous units, and development of regression relationships between in situ reference and remote sensing data using a machine learning approach. An in situ soil survey was conducted to examine the soils' physical and chemical properties, fertility status, and organic matter. The data of soil survey were used to create soil maps to evaluate key characteristics of soils, and their influence on Avicennia marina in Eastern Mangrove Lagoon National Park. The results of this study provide new insights into Avicennia marina canopy population, structure, aboveground biomass, and soil properties in Abu Dhabi, as data in such arid environments is lacking. This valuable information can help in managing and preserving this unique ecosystem.

    Neonatal diabetes mellitus (NDM) can be transient (TNDM) or permanent (PNDM). Data on NDM from the Gulf region are limited to few studies on PNDM.The objective of this study was to describe the genetic and clinical spectrum of NDM and estimate its incidence in AbuDhabi, capital of the United Arab Emirate (UAE). Patients were identified from the pediatric diabetes clinics and sequencing of known NDM genes was conducted in all families. Twenty-five patients were identified. Incidence during 1985-2013 was 1:29,241 Live births. Twenty-three out of twenty-five had PNDM (incidence 1:31,900) and 2/25 had TNDM (incidence 1:350,903). Eleven out of twenty-five had extra-pancreatic features and three had pancreatic aplasia. The genetic cause was detected in 21/25 (84%). Of the PNDM patients, nine had recessive EIF2AK3 mutations, six had homozygous INS mutations, two with deletion of the PTF1A enhancer, one was heterozygous for KCNJ11 mutation, one harboured a novel ABCC8 variant, and 4/21 without mutations in all known PNDM genes. One TNDM patient had a 6q24 methylation defect and another was homozygous for the INS c-331C>G mutation. This mutation also caused permanent diabetes with variable age of onset from birth to 18 years. The parents of a child with Wolcott-Rallison syndrome had a healthy girl following pre-implantation genetic diagnosis. The child with KCNJ11 mutation was successfully switched from insulin to oral sulphonylurea. The incidence of PNDM in Abu Dhabi is among the highest in the world and its spectrum is different from Europe and USA. In our cohort, genetic testing has significant implications for the clinical management. PMID:26463504

    Full Text Available Landfill sites receive 92% of total annual solid waste produced by municipalities in the emirate of Abu Dhabi. In this study, candidate sites for an appropriate landfill location for the Abu Dhabi municipal area are determined by integrating geographic information systems (GIS and multi-criteria evaluation (MCE analysis. To identify appropriate landfill sites, eight input map layers including proximity to urban areas, proximity to wells and water table depth, geology and topography, proximity to touristic and archeological sites, distance from roads network, distance from drainage networks, and land slope are used in constraint mapping. A final map was generated which identified potential areas showing suitability for the location of the landfill site. Results revealed that 30% of the study area was identified as highly suitable, 25% as suitable, and 45% as unsuitable. The selection of the final landfill site, however, requires further field research.

    Full Text Available This paper deals with how climate and local culture specifics contribute to urban diversity, and how they affect the way urban spaces are being conceived, planned and designed. The authors argue that regardless of the globally accepted principles of sustainability which emphasize smart responses, diversity and culture as the prime drives in urban development of, cities around the world are continually experiencing the all-alike solutions, which often compromise their identity and character. Having taken the genuine stands of the philosophy as a starting point for examining the subject, the authors explore and present how the climate specifics, along with the uniqueness of local culture, lead toward the solutions which make a difference to their cities. The discussion is illustrated by the case study the authors were engaged in, the Mussafah District project in Abu Dhabi, a redevelopment proposal recently initiated and developed by International Society of Urban and Regional Planners -ISOCARP and Urban Planning Council of Abu Dhabi.

    2016-01-01

    Background: Data on the use of emergency medical services (EMS) by patients with cardiac conditions in the Gulf region are scarce, and prior studies have suggested underutilization. Patient perception and knowledge of EMS care is critical to proper utilization of such services. Objectives: To estimate utilization, knowledge, and perceptions of EMS among patients with ST-elevation myocardial infarction (STEMI) in the Emirate of Abu Dhabi. Methods: We conducted a multicenter prospective study of consecutive patients admitted with STEMI in four government-operated hospitals in Abu Dhabi. Semi-structured interviews were conducted with patients to assess the rationale for choosing their prehospital mode of transport and their knowledge of EMS services. Results: Of 587 patients with STEMI (age 51 ± 11 years, male 95%), only 15% presented through EMS, and the remainder came via private transport. Over half of the participants (55%) stated that they did not know the telephone number for EMS. The most common reasons stated for not using EMS were that private transport was quicker (40%) or easier (11%). A small percentage of participants (7%) did not use EMS because they did not think their symptoms were cardiac-related or warranted an EMS call. Stated reasons for not using EMS did not significantly differ by age, gender, or primary language of the patients. Conclusions: EMS care for STEMI is grossly underutilized in Abu Dhabi. Patient knowledge and perceptions may contribute to underutilization, and public education efforts are needed to raise their perception and knowledge of EMS. PMID:27512532

    Bed-parallel stylolites are a widespread diagenetic feature in Lower Cretaceous limestone reservoirs, Abu Dhabi, United Arab Emirates (UAE). Diagenetic calcite, dolomite, kaolin and small amounts of pyrite, fluorite, anhydrite and sphalerite occur along and in the vicinity of the stylolites. Petrographic observations, negative δ18OVPDB, fluid inclusion microthermometry, and enrichment in 87Sr suggest that these cements have precipitated from hot basinal brines, which migrated along the stylolites and genetically related microfractures (tension gashes). Fluid migration was presumably related to lateral tectonic compression events related to the foreland basin formation. The low solubility of Al3 + in formation waters suggests that kaolin precipitation was linked to derivation of organic acids during organic matter maturation, probably in siliciclastic source rocks. The mass released from stylolitization was presumably re-precipitated as macro- and microcrystalline calcite cement in the host limestones. The flanks of the oilfield (water zone) display more frequent presence and higher amplitude of stylolites, lower porosity and permeability, higher homogenization temperatures and more radiogenic composition of carbonates compared to the crest (oil zone). This indicates that oil emplacement retards diagenesis. This study demonstrates that stylolitization plays a crucial role in fluid flow and diagenesis of carbonate reservoirs during basin evolution.

    Full Text Available Rapid economic and cultural transition in the United Arab Emirates (UAE has been accompanied by new challenges to public health; most notably a rapid rise in chronic disease. Breastfeeding is known to improve health outcomes in adulthood, is associated with reduced risk of developing chronic disease, and is therefore an important public health issue for this rapidly increasing population. Factors associated with infant feeding practices were examined in a cohort of 125 Emirati women and their infants, with data collected at birth and 3, 6 and 15 months postpartum by questionnaires and interviews. Participants were recruited in the Corniche Hospital, the main maternity hospital in the city of Abu Dhabi. Factors affecting the duration of breastfeeding and the introduction of complementary foods were investigated using univariate and multivariate statistics. Recommended infant feeding practices, such as exclusive breastfeeding for the first six months of life and timely introduction of appropriate complementary foods, were poorly adhered to. Factors implicated in early cessation of breastfeeding included: time to first breastfeed, mother’s education level, employment status and early introduction of complementary foods.

    In this study a relationship between the seismic wavelength and the scale of heterogeneity in the propagating medium has been examined. The relationship estimates the size of heterogeneity that significantly affects the wave propagation at a specific frequency, and enables a decrease in the calculation time of wave scattering estimation. The relationship was applied in analyzing synthetic and Vertical Seismic Profiling (VSP) data obtained from an onshore oilfield in the Emirate of Abu Dhabi, United Arab Emirates. Prior to estimation of the attenuation, a robust processing workflow was applied to both synthetic and recorded data to increase the Signal-to-Noise Ratio (SNR). Two conventional methods of spectral ratio and centroid frequency shift methods were applied to estimate the attenuation from the extracted seismic waveforms in addition to a new method based on seismic interferometry. The attenuation profiles derived from the three approaches demonstrated similar variation, however the interferometry method resulted in greater depth resolution, differences in attenuation magnitude. Furthermore, the attenuation profiles revealed significant contribution of scattering on seismic wave attenuation. The results obtained from the seismic interferometry method revealed estimated scattering attenuation ranges from 0 to 0.1 and estimated intrinsic attenuation can reach 0.2. The subsurface of the studied zones is known to be highly porous and permeable, which suggest that the mechanism of the intrinsic attenuation is probably the interactions between pore fluids and solids.

    The Gulf countries are largely dependent on exporting oil and natural gas for their national budgets. They mainly use domestic fossil fuels for their domestic energy supply. In spite of favorable geographic conditions, especially for solar energy, renewable energies are still a niche application. Abu Dhabi, besides Dubai, the most important emirate in the United Arab Emirates (UAE), has now started a process of 'transforming oil wealth into renewable energy leadership', and has set the long-term goal of a 'transition from a 20th Century, carbon-based economy into a 21st Century sustainable economy'. This article is a case study about 'Masdar City', a planned carbon-neutral town in Abu Dhabi. The article describes the key characteristics of Masdar City, analyses the drivers behind the project, identifies the main actors for its implementation, and seeks obstacles to creation and development as well as the policy behind Masdar City. Finally, a first judgment of possible diffusion effects of the project is done. (author)

    Landfilling the organic fraction of municipal solid waste (OFMSW) leads to greenhouse gas emissions and loss of valuable resources. Sustainable and cost efficient solutions need to be developed to solve this problem. This study evaluates the feasibility of using dark fermentation (DF) to convert the OFMSW to volatile fatty acids (VFAs), fertilizer and H2. The VFAs in the DF effluent can be used directly as substrate for subsequent bioprocesses or purified from the effluent for industrial use. DF of the OFMSW in Abu Dhabi will be economically sustainable once VFA purification can be accomplished on large scale for less than 15USD/m(3)(effluent). With a VFA minimum selling price of 330 USD/tCOD, DF provides a competitive carbon source to sugar. Furthermore, DF is likely to use less energy than conventional processes that produce VFAs, fertilizer and H2. This makes DF of OFMSW a promising waste treatment technology and biorefinery platform.

  19. Abrasive Blasting Unit (ABU) - 16270

    International Nuclear Information System (INIS)

    NUKEM Technologies was contracted to supply a dry, automated drum belt (tumbling) Abrasive Blasting Unit (ABU) to the Joint Research Centre of the European Commission in Ispra, Italy. The ABU was installed in the centralised radioactive waste management area of the JRC-Ispra site in Italy. The unit is to be employed for the decontamination to clearance levels of slightly contaminated metal components and, where practical, concrete or heavy concrete (density ∼3200 kg/m3) blocks arising from the dismantling of nuclear facilities. The presentation is based on the successful construction and installation of the ABU at the JRC Ispra site. Among the several possibilities of adapting conventional abrasive units to nuclear applications, an automatic tumbling machine was preferred, due to the larger output and (mainly) for the ease of operation, with minimum direct handling of contaminated material by operators, thus satisfying the ALARA principle. Consideration was also given to Belgoprocess' successful experience with a predecessor, similar unit. After adequate size reduction batches of up to about 800 kg of material to be decontaminated are automatically introduced into the blasting chamber. Pieces between 100 mm and 800 mm long, between 100 mm and 500 mm wide and between 5 mm and 300 mm high can be effectively treated in the unit, the maximum weight of a single piece being limited to 100 kg. Short lengths of pipe may be included; the final dimensions of pipe to be decontaminated will be established during the nuclear commissioning tests. Other components with hard-to-reach surfaces may also be included. The content of the chamber is tumbled by two bladed drums, while sharp steel grit is sprayed onto the contaminated components, thus removing the surface layer including any contamination. From experience, 30 minutes of treatment is sufficient to remove contamination to levels below expected clearance levels for most materials. The decontaminated components are removed

  2. Design multiperiod optimization model for the electricity sector under uncertainty – A case study of the Emirate of Abu Dhabi

    International Nuclear Information System (INIS)

    Highlights: • Generic and novel multiperiod stochastic model is developed for UAE power sector. • The presented model is formulated as a mixed-integer linear programing problem. • Power infrastructure over 25 years is outlined under natural gas price uncertainty. • Low electricity prices and better social and environmental benefits were obtained. - Abstract: In this study, a multiperiod model that considers uncertainty in the gas feedstock fuel price is developed for the optimal design of electric power systems. The optimization problem was formulated as a multiperiod stochastic programming model using the GAMS® modeling system. Previous studies have analyzed the United Arab Emirates’ (UAE) power infrastructure either using a deterministic point of view or simulation tools (e.g., MESSAGE and MARKAL). These previous research has demonstrated that natural gas will remain playing a significant role as key feedstock fuel in the UAE’s power sector. However, the present work is designed to be the first to consider different supply options for the natural gas feedstock (i.e., domestic, pipeline imports, and LNG imports) and electricity imports in the UAE power sector. Moreover, the natural gas supply and electricity import options are considered to be decision variables in the problem’s formulation. Additionally, the considered case studies assumed a realistically existing power infrastructure for the UAE, whereas previous works considered the planning of the UAE power infrastructure as a Greenfield project. Also, to the authors’ knowledge this is the first work to consider a robust optimization model for planning the UAE power infrastructure under uncertainty in the long term horizon. The model was used to study the planning of the power plant infrastructure in the UAE between 2015 and 2040 under uncertainty in the natural gas price. The optimization results show that the model is a valuable tool for planning the optimal power plant infrastructure of the country, reducing levelized electricity costs, and mitigating social and environmental damages

    Full Text Available AbstractA Western-style of theatre has developed in Bali since the turnof the twentieth century, but it has rarely attracted scholarly attention. Studies on the performing arts in Bali have mainly focused on Balinese (traditional dance and drama. This should come as no surprise given that Balinese dance and drama have developed as a broad and inseparable part of Balinese custom and religious practice. Against this phenomena, this article traces the development of Western-style theatre in Bali through the artistic activities of the prominent playwright, performer and director, Abu Bakar. From the 1960s until the present, Abu Bakar has been an active promoter of Westernsty letheatre in Bali as well as in the main cities of Java andeven in Singapore. He has also has helped students and theatre groups around Bali to study and perform theatre. Initially, Abu Bakar established his own theatre group, Poliklinik, which hascontinued to stage performances as well as collaborating with young people or student theatre study clubs. His extensiverecord of artistic activity has been recorded in newspaper reports and reviews and these form the main source of documentation in this article. By examining qualitative data collected from newspaper archives and interviews, including with Abu Bakar, this article proposes a contemporary historyof theatre or modern drama in Bali.

    Variations in morphology, fatty acids, pigments and cyanobacterial community composition were studied in microbial mats across intertidal flats of the arid Arabian Gulf coast. These mats experience combined extreme conditions of salinity, temperature, UV radiation and desiccation depending on their tidal position. Different mat forms were observed depending on the topology of the coast and location. The mats contained 63 fatty acids in different proportions. The increased amounts of unsaturated fatty acids (12-39%) and the trans/cis ratio (0.6-1.6%) of the cyanobacterial fatty acid n-18:1omega9 in the higher tidal mats suggested an adaptation of the mat microorganisms to environmental stress. Chlorophyll a concentrations suggested lower cyanobacterial abundance in the higher than in the lower intertidal mats. Scytonemin concentrations were dependent on the increase in solar irradiation, salinity and desiccation. The mats showed richness in cyanobacterial species, with Microcoleus chthonoplastes and Lyngbya aestuarii morphotypes as the dominant cyanobacteria. Denaturing gradient gel electrophoresis patterns suggested shifts in the cyanobacterial community dependent on drainage efficiency and salinity from lower to higher tidal zones. We conclude that the topology of the coast and the variable extreme environmental conditions across the tidal flat determine the distribution of microbial mats as well as the presence or absence of different microorganisms.

    As it can be seen on satellite images, geological, and geomorphological maps, the Jebel Hafit and its foothills are a rare example of landforms developed at the transition between a compressive area in the east, i.e. the Northern Oman Mountains, and a stable cratonic platform in the west, i.e. the Arabic Platform which, from a structural point of view, represents the foreland of the previous folded domain. The mountains of Jebel Hafit formed in response to two main orogenic events in Late Cretaceous (obduction of Semail Ophiolite and associated rocks) and in the Late Eocene to Miocene (formation of foreland folds). Concerning the environment, landforms of the Jebel Hafit appears today under extreme arid climatic conditions. But, as it is evidenced by the density and variety of archaeological remains that have led to the inscription of the sites on the World Heritage List, the situation was different yesterday. It is well known that desert have changed through time, so present conditions may not necessarily be those that have moulded desert surface. This is particularly clear when we travel back by the thought from present to a more or less distant period in the past. It is therefore legitimate to study the biophysical remnants of paleo-environments, which accompany the development of human settlements and the increasing impact of societies on the environment. A particular challenge will be to discriminate clearly the effect of the active present-day climatic-driven processes (such as thermal fatigue weathering, salt weathering, wind corrasion, sporadic flooding…) and those of prehistoric times, which requires a geoarchaeological and paleoenvironmental approach of the Holocene as a whole and also before (Late Pleistocene). An important point not to be forgotten is that severe rainstorms happen on the area only at a highly variable temporal scale, especially hurricanes coming from the Indian Ocean and that may travel west of the Oman Mountains. At the level of human settlements and occupation, it is possible to characterize a threefold transition: first, the former transition between the pre-Islamic prehistoric societies and the development of Muslim societies; second, the more recent transition between the traditional historical society (farmers) and the contemporary society, characterized by the growth of urbanization, the creation of modern transport infrastructure and the concomitant growth of tourist flows; third, the current transition between the yesterday and tomorrow Al Ain City, due to the transformation of a local town centred on national economics all along the second half of the twentieth century, into an international town more open to the wider world with the management of a possible increased 20 % of tourist flow because of the inscription of Cultural Sites of Al Ain on the UNESCO's World Heritage List. It is not possible to completely ignore the fact that the Jebel Hafit and its foothills are partly crossed by an international boundary. In case of political tensions, this may cause some difficulties for the management of this territory, with contradictory requirements between security, tourism, traditional land use, and scientific research.

  14. Opening Address [International Conference on Human Resource Development for Introducing and Expanding Nuclear Power Programmes, Abu Dhabi (United Arab Emirates), 14-18 March 2010

    International Nuclear Information System (INIS)

    Full text: It is a pleasure for me to open this IAEA conference on Human Resource Development for Introducing and Expanding Nuclear Power Programmes. I am very grateful to the Government of the United Arab Emirates for hosting this important event. As you know, the world is witnessing a resurgence of interest in nuclear power. The IAEA has projects on introducing nuclear power with no fewer than 58 of our Member States. We expect between 10 and 25 new countries to bring their first nuclear power plants on line by 2030. These are momentous changes. However, some countries are concerned about a possible shortage of skilled professionals in the nuclear field in the coming decades. The generation of professionals who built and led the nuclear power industry for much of the past 50 years is approaching retirement and in some countries not enough students are coming up through the educational system to take their place. Naturally, we, at the IAEA, want to do all we can to help Member States address this issue. That is why we have organized this conference. The situation is different in each country. For countries with expanding nuclear power programmes, the challenge is to scale up their existing education and training in order to have the required qualified workforce on time. Countries planning to supply nuclear technology to others must not only meet their national human resource needs, but also be able to transfer education and training capacity together with the technology they provide. Finally, countries embarking on nuclear power cannot become too dependent on their technology supplier and need to develop their own home grown expertise and skills base. The IAEA would be happy to help interested States to formulate country specific policies on human resource development, education, training and knowledge management in support of nuclear power programmes. We could also help countries make better use of training facilities, research reactors and other educational infrastructure. We could play a role in ensuring high standards for nuclear education and training and establish a framework for countries to recognize each other's educational qualifications. I look forward to hearing the ideas of this very knowledgeable and distinguished audience and wish you every success with the conference. (author)

    This work aimed for pyrite separation from Abu Tartur black shale as a source of sulfur to be an added economic value of Abu Tartur area. The considered samples in the present work were collected from a core drilled in Abu Tartur plateau representing the pyrite-rich black shale of the U. Cretaceous age. Sample characterization was carried out using petrographic microscope, XRD, DTA/DTG, C/S and XRF techniques. Clay minerals, silt-sized quartz, calcite, and hematite were the main minerals associating pyr-ite (5.34%). Liberation behavior of the sample was about 80%below 5 lm. Sample processing was achieved through one-day soaking followed by classification using 1 inch Mozley hydro-cyclone where about 35.5% by weight went to underflow and 64.5% went to overflow. The underflow product was subjected to an advanced gravity separation process using SB-40 Falcon Concentrator through a CCD statistical design prepared by Design-Expert 6.0 software proposed to opti-mize the separation process through a study for the effects of frequency (Hz) and water pressure (Psi) on both assay and recovery of the sulfur-rich heavy fraction. A heavy concentrate weighed 10.90%with inorganic sulfur content reached 11.37%(21.24%pyrite) with overall recovery (50.01%) was obtained after two cleaning at the optimum conditions.

    2002-08-01

    Structural and maturation studies in the northwest of the Muglad Basin, Sudan showed a thick sedimentary section up to 9000 m in the deep sub-basins and an average of about 6000 m in the Sharaf-Abu Gabra Ridge. The isopach map of the Lower Cretaceous Abu Gabra-Sharaf formations, which contain source rocks, showed a thickness of sedimentary section between 2000 and 5000 m. The burial history showed high subsidence rates during the first rifting phase with relatively low subsidence rates during the following two phases in this part of the basin. Significant erosion of the sedimentary section occurred in the ridge area during Miocene and Cenomanian-Albian times. The geothermal gradients in the modelled wells range between 18 and 27.5 °C/km corresponding to the relatively wide range of present day heat flow of between 37 and 63 mW/m 2, averaging 50 mW/m 2. Heat flow history curves consistent with vitrinite reflectance data were adopted with elevated high heat flow (75 mW/m 2) during the first rifting phase followed by minor peaks (average 60 mW/m 2) during the second and the third rifting phases. Application of a kinetic vitrinite maturation model resulted in a present day oil window between 2000 and 4500 m. The source rock of the Abu Gabra (AG) and Sharaf (SH) formations, which has an average total organic carbon of 1.0% and hydrogen index (HI) of 280, was modelled for hydrocarbon generation. The section was divided into four layers; AG-1 (Albian), AG-2 (Aptian), SH-1 (Barremian) and SH-2 (Neocomian). Conditions for hydrocarbon generation are present throughout the Sharaf formation and in AG-2. The generation model suggests an average generation amount of 4 mgHC/g rock in the lower three modelled layers with a timing range between 120 Ma and the present. Total calculated oil volume is about 370 US billion bbls and the expected volume expelled and migrated (40%) is 150 US billion bbls. The total gas expelled and migrated (90%) is 1600 US trillion cu ft. Retention of

    2015-12-01

    The occurrence of hydrocarbons is closely linked to the elements of petroleum system history of the BED 3 and Sitra 8 oilfields, which has created multiple reservoir and seal combinations. BED 3 Field and Sitra concessions occupy the northwestern part of the Abu Gharadig Basin and extends between latitudes 29°45‧ and 30°05‧N and longitudes 27°30‧ and 28°10‧E. The comprehensive integration of the geo-related data and the interpretation of the well logging, geochemical, seismic data in time domain and depth and sealing mechanisms explain the occurrence of hydrocarbons in some certain reservoirs during cretaceous age and other reservoirs in the same fields don't have any hydrocarbon accumulation. Detailed seismic data interpretation was performed for the target units of BED 3 and Sitra 8 oilfields in time domain and converted to depth domain. Sitra 8 Field is a three-way dip closure bounded by NW-SE faults while BED 3 field is represented by a WNW-ESE trending horst dipping to the east. The Albian-Cenomanian Kharita Formation has a high energy shallow marine shelf environment and considered as the main pay zone in the BED 3 oilfield. On the other hand, Kharita sands are dry in the Sitra 8 Field. Also, the shallow marine shale, sandstone, limestone and dolomite interbeds of the Abu Roash G Member are another hydrocarbon bearing reservoir in the Sitra 8 Field. Sealing mechanisms were applied to explain why certain reservoirs have hydrocarbon and others don't. Allan's juxtaposition diagram for the main faults in the study area shows that Kharita sands in BED 3 area have excellent juxtaposition as Kharita juxtapose to upper Bahariya and intra Bahariya, which consist of shale and limestone. Abu Roash G sands in BED 3 area have bad juxtaposition as the Abu Roash G juxtapose to Abu Roash C sand (sand juxtaposed sand). Allan's diagram shows that the Abu Roash G reservoir (main target) in Sitra 8 is juxtaposing Abu Roash D which is composed of limestone and shale

    2002-01-01

    The Campanian-Maastrichtian phosphatic deposits in Egypt, called the Duwi Formation, comprise a part of the extensive Middle East to North African phosphogenic province of Late Cretaceous to Paleogene age. The province holds the greatest accumulation of phosphorites in the geological history, possibly in excess of 70 billion metric tons. The phosphate resources in Egypt alone exceed 3 billion metric tons. Two-third of these three billions occur only in the Abu-Tartur area. Among the phosphorite deposits in Egypt, the phosphorites of the Abu-Tartur area are characterized by high contents of iron ranging from 3 % to 7% with an average of 5 %. The detailed mineralogical and geochemical studies on the Abu-Tartur phosphorites revealed that iron is found in the form of pyrite, ankerite, clay minerals, microinclusions, and iron oxide.Pyrite, which is the major fraction, occurs as filling cement and partial to complete replacement of phosphatic grains and confined to the fresh phosphorites while iron oxide occurs as cryptocrystalline aggregates of red to brown particles and is confined to the weathered outcrops. Exclusive relations between pyrite in the fresh phosphorite samples inside the Abu-Tartur mine and iron oxide in the equivalent horizon of the weathered exposure indicated that iron oxide was formed by the oxidation of pyrite as a result of weathering. All of these forms harm the quality of ore, manufacturing processes, and the produced phosphoric acid and fertilizers.

However, even from a more detailed Latin translation, the observations and logic behind Abu Mashar's conclusion were not understandable. We present here the original Arabic text (MS Ankara, Saib 199) together with our translation and interpretation: Abu Mashar reported that he had observed Venus in (or projected onto) the tail of a comet and concluded that the comet was behind Venus, because he had observed the extinction of Venus due to the cometary tail to be negligible (light of Venus was unimpaired). He then concluded that the comet would be located behind Venus. He also mentioned that others had observed Jupiter and Saturn in cometary...

  19. National Report: Slovakia [International Conference on the Safety and Security of Radioactive Sources: Maintaining Continuous Global Control of Sources throughout their Life Cycle, Abu Dhabi (United Arab Emirates), 27-31 October 2013

    International Nuclear Information System (INIS)

    Slovak Republic (The Public Health Authority of The Slovak Republic - PHA SR) has collaborated from the very beginning on a preparation of the important IAEA document - the Code of Conduct. Following its official approval, the Code of Conduct was implemented into the national legislature( Act,governmental orders, regulations, guidelines, pamphlets). The important task was to resolve an issue of captured orphan sources and other intercepted radiation sources, i.e. to craft a system structure for handling these orphan sources. Serving this purpose, in the 90-ties (yrs. 1995 - 1999), the Ministry of Health SR (PHA SR) had elaborated materials which were consequently adopted by the government as a basis for building the system of guidelines on handling the ionizing sources. There were several organizations selected and designated for this purpose of handling detained radioactive materials. E.g. ''Jadrová vyraďovacia spoločnosť'' (Nuclear Waste Council) and a private company ''HUMA-LAB APEKO'', to name a few. There were a couple requirements for these entities: - Possession of a permit to handle radioactive materials - Hot chamber to ensure safe disposition of retained radioactive materials - Proper storage conditions Furthermore, it was very important to allocate the finances to address these matters. The Slovak legislature had stated that the issue of handling the orphan sources would be financed by a governmental fund for Radiation Facility Liquidation. The whole process of tending the issue of capturing the radiation sources has been overseen by three cooperating institutions: PHA SR - monitoring entity, State Police, and Safety Unit ensuring the proper storage of radioactive materials. The specific purpose and particular duties of each institution are encompassed in a guideline manual. It is imperative to inform IAEA of all interceptions and detentions of radiation sources. Given that the most problems and radioactive materials have occurred in junk yards and facilities of metal waste storage, the PHA SR professionals continuously focus on providing the facility staff with informational brochures, leaflets and extensive training to learn and recognize common radiation sources, their usage, etc

    International Nuclear Information System (INIS)

    Safety and security in the nuclear domain have been developed and improved side by side with the continuous growth of the use of nuclear technologies in Brazil. The large range of radioactive source applications compose, together with the power plants and nuclear fuel cycle facilities, a diversified panorama in the field and have demanded a permanent regulatory action in order to ensure that these sources are safely manned and security protected during their life cycle. In this sense the Code of Conduct on the Safety and Security of Radioactive Sources (Code of Conduct) and its associated document, the Guidance on the Import and Export of Radioactive Sources (Guidance), have been considered a milestone for the improvement of the national regulatory system. Brazil has written to the International Atomic Energy Agency (IAEA) Director General, expressing their support for the Code of Conduct and the Guidance as well as nominated a point of contact for the purpose of facilitating the export and/or import of radioactive sources in accordance with the Code Conduct and the Guidance

    International Nuclear Information System (INIS)

    In this report it is intended to describe the status of Argentina in relation to the issues proposed. a) The infrastructure for regulatory control Argentina has a Regulatory Authority, the AUTORIDAD REGULATORIA NUCLEAR (ARN). It is an autonomous body reporting to the President of Argentina. It was created by the “NUCLEAR ACTIVITY NATIONAL ACT”, Nº 24804. This Law empowers ARN to regulate and control the nuclear activity with regard to radiological and nuclear safety, physical protection and nuclear non-proliferation issues. The objective of ARN is to establish, develop and enforce a regulatory system applicable to all nuclear activities carried out in Argentina. ARN is independent, nowadays, of any organization dedicated to the use or the promotion of nuclear energy in any of its forms and is provided with adequate financial resources for the fulfillment of its mission. ARN faculties are: • Issue of regulatory standards: In relation to this subject the most relevant issues to remark during this three years period is that some of the Standards have been updated, on Gammagraphy operation and personnel requirements (2010) AR 7.9.1 and AR 7.11.1 and their regulatory related guidance AR.5; on transport of radioactive material (2012) AR 10.16.1 and generic exemption levels (2010) AR.6. • Grant the corresponding licenses/authorizations to nuclear installations and personnel, including the import export ones. • Grant the corresponding approval Certificates in the case of transport of radioactive material. • Submit requirements to the Responsible Organizations. • Carry out inspections and audits to verify compliance with licenses and authorizations issued and the appropriate Standards. • Perform independent studies and evaluations. • Apply sanctions in the case of non-compliance with any obligation by the license holder. • Approve emergency plans and procedures. • Coordinate the actions in case of radiological/nuclear emergencies. The licensing system, in Argentina, is based, in general, in performance safety criteria that have been taken from the international recommendations. It places the prime responsibility for the safe management of, and the security of, radioactive sources on the persons being granted the licenses and permissions

    International Nuclear Information System (INIS)

    International cooperation among nuclear regulatory bodies is important for effective nuclear safety and security regulation at the national and international level. This is particularly important given the increased interest in nuclear power worldwide and in enhanced focus on climate change. In this context, mature regulatory bodies should consider support for new countries, better control of radioactive sources, and enhancement of international cooperation for the global nuclear safety and security regime, including application of international legal instruments, knowledge networks, safety standards and security guidance. Regulators should also focus on developing an open, transparent process with appropriate mechanisms for interaction with the public. While effective regulatory bodies have their roles at the national and international levels, the expectation of the society and the role of international organizations for assuring an effective global nuclear safety and security regime; governments are expected to undertake the roles and responsibilities for the global adherence to international instruments relevant to nuclear safety and security, in establishing and maintaining the legal and governmental infrastructure for safety and security. While it is acknowledged that safety performance indicators have shown marked improvement over the last two decades, it is necessary to avoid complacency and to continually improve and strengthen the existing global nuclear safety and security regime so that the use of nuclear technologies can be introduced or expanded in a safe and credible manner to meet the world’s needs for human well-being, environmental protection, growth and sustainable development

    International Nuclear Information System (INIS)

    Normally, all radioisotopes subject to regulation are prescribed by the Nuclear Safety Act to be controlled and handled in accordance with the law from production to disposal. In particular, sources classified as IAEA Category 1·2 are strictly managed for the purpose of security as death can result from just a few minutes to days of contact if they are stolen or lost or used intentionally for terrorism. At present, Korea Institute of Nuclear nonproliferation and Control (KINAC) is responsible for the physical protection of nuclear power plants and nuclear materials, while Korea Institute of Nuclear Safety (KINS) is in charge of security of radioactive materials. In order to strengthen the security of nuclear and other radioactive materials, various activities are conducted such as the application of detailed guidelines on the security in the safety assessment stage, the application of a real-time monitoring system for radioisotopes that could potentially be used for terrorist activities, and implementing the recommendations and guidelines of IAEA security. This report covers the current domestic implementation of the Code of Conduct on the Safety and Security of Radioactive Sources and the Guidance on the Import and Export of Radioactive Sources, and introduces the Radiation Source Location Tracking System, which is currently in operation to implement the Code of Conduct on the Safety and Security of Radioactive Sources

  7. National Report South Africa [International Conference on the Safety and Security of Radioactive Sources: Maintaining Continuous Global Control of Sources throughout their Life Cycle, Abu Dhabi (United Arab Emirates), 27-31 October 2013

    International Nuclear Information System (INIS)

    South Africa has two regulators: the National Nuclear Regulator (NNR) is mandated by the NNR Act to regulate nuclear facilities, while the Directorate: Radiation Control in the Department of Health regulates radioactive sources as mandated by the Hazardous Substances Act (15 of 1973) and the associated Regulations R246 & R247 of 1993. The Directorate: Radiation Control is responsible for the regulation of all medical and industrial applications of radioactive sources and generators of ionizing radiation. South Africa has two manufacturers of radioactive sources, which export radioactive sources to more than 50 countries internationally. The country plays a major role in Africa by exporting imported and locally manufactured radioactive sources to many other African countries. Many South African-based operators of equipment using radionuclides do contract work in the rest of Africa. South Africa has a large number of mines, industries and construction companies, which comprise about 90% of applications of radioactive sources. There are also several industrial, sample and blood irradiators. The remaining 10% of radioactive sources are applied in the medical industry. About 80% of generators of ionizing radiation are applied in the medical sector, the remainder in industry. The Directorate: Radiation Control faces several difficulties. The three most urgent difficulties to overcome are listed in par. 2.1.1. Shortcomings have been identified through self-assessment projects already conducted under the auspices of the IAEA and still to be conducted in other areas. The Directorate is currently in a process of strengthening its regulatory control infrastructure through technical cooperation projects and the development of strategies to address shortcomings.

    International Nuclear Information System (INIS)

    The IAEA has established a Working Group on Radioactive Sources Security, which held its first two meetings in November 2012 and May 2013. The next meeting is planned for 2014. This group explores the security concerns specific to high activity radioactive sources and seeks to improve the coordination of efforts to provide assistance related to those concerns. Nuclear safety has a long history, and there have been fewer drastic changes but the IAEA continues to publish and update its safety publications. We also develop and enhance our tools and services to improve support for our Member States. Together with the increased emphasis on security, there is also an ongoing debate on interfaces, integration, coordination or synergies between safety and security. While it may seem intuitive that safety and security should be compatible, there remains considerable room for further clarification

    Whenever the topic of safety and security of radioactive sources is discussed, the issue of the long term management of and funding for disused sources arises. The absence of clear routes for the safe and secure handling of disused sources, including legacy sources, is a vulnerability of the existing international system. The long title of this Conference — maintaining continuous global control of sources throughout their life cycle — reminds us that the life cycle of control needs to include the end-of-useful-life stage. Here in the United Arab Emirates, we believe that we have made progress in securing the radioactive sources used in our industries. You will hear about FANR’s (Federal Authority for Nuclear Regulation) regulations both for the safety and security of radioactive sources. More importantly, you will hear about the practical arrangements we are implementing, working with licensees, to see that effective security plans and arrangements are put in place: both for sources at company headquarters and in the field, and also in transport

  10. National report (Mauritania) for the International Conference on the Safety and Security of Radioactive Sources: Maintaining the Continuous Global Control of Sources throughout their Life Cycle in Abu Dhabi, 27-31 October 2013

    International Nuclear Information System (INIS)

    The Mauritania is a country located in the northwest of Africa. The country is very large in size (about one million square KM) with 3 million inhabitants. Services and population are concentrated in the capital Nouakchott. The use of ionizing radiation is fairly recent in Mauritania. It is divided into two main sectors: a. The medical sector: The medical use is quite broad and varies from diagnosis to treatment. Thus, there is tens of diagnostic centers with a simple means of conventional radiography, but also some medical scanners. There is also a National Oncology Center with a linear accelerator. This center has been operational since 2011. b. Industrial sector: The industrial radiography is used in companies and public works buildings in Mauritania. It is also used in some companies prospecting and mining. Recently, some uranium mines has just been discovered and treatment is expected soon. Including fuel and waste, we can also say that in Mauritania, there are NORM (NATURELLY Occupational Radioactive Materials). The problem of security of radioactive sources and disused sources is asked since the beginning of use of ionizing radiation. Indeed, we do not know the exact number of orphan radiological sources in Mauritania. The country is vast in area and the National Authority for Radiation Protection, Security and Nuclear Safety has identified at this time very few sources, some of which in northern Mauritania. Even, the National Center of Oncology has also soon open its nuclear medicine department and it will certainly reject a lot of radioactive waste. To prevent these sources fall into the wrong hands, the Mauritanian government, via the ARSN, decided to confine the found sources and continue the search for lost sources, despite the limited means at their disposal

  17. Radiological impacts of natural radioactivity in Abu-Tartor phosphate deposits, Egypt

    International Nuclear Information System (INIS)

    Phosphate and environmental samples were collected from Abu Tartor phosphate mine and the surrounding region. The activity concentration of 226Ra (238U) series, 232Th series and 40K were measured using a gamma-ray spectrometer. The activities of uranium isotopes (238U, 235U and 234U) and 210Pb were measured using an alpha spectrometer and a low-background proportional gas counting system, respectively, after radiochemical separation. The results are discussed and compared with the levels in phosphate rocks from different countries. It seems that the Abu Tartor phosphate deposit has the lowest radioactivity level of exploited phosphate of sedimentary origin. 226Ra/238U, 210Pb/226Ra, 234U/238U and 226Ra/228Ra activity ratios were calculated and are discussed. The radioactivity levels in the surrounding region and the calculated exposure dose (nGy/h) will be considered as a pre-operational baseline to estimate the possible radiological impacts due to mining, processing and future phosphate industrial activities. To minimize these impacts, the processing wastes should be recycled to the greatest possible extent

    2014-01-01

    Full Text Available Electrical Resistivity Tomography (ERT survey was carried out at Abu Baara earth dam in northwestern Syria, in order to delineate potential pathways of leakage occurring through the subsurface structure close to the dam body. The survey was performed along two straight measuring profiles of 715 and 430 m length in up- and downstream sides of the dam’s embankment. The analysis of the inverted ERT sections revealed the presence of fractured and karstified limestone rocks which constitute the shallow bedrock of the dam reservoir. Several subsurface structural anomalies were identified within the fractured bedrock, most of which are associated with probable karstic cavities, voids, and discontinuity features developed within the carbonates rocks. Moreover, results also showed the occurrence of a distinguished subsiding structure coinciding with main valley course. Accordingly, it is believed that the bedrock and the other detected features are the main potential causes of water leakage from the dam’s reservoir.

    Full Text Available After fifty years from the Salvage of the Abu Simbel Temples it has been possible to experiment the contemporary photo-modeling tools beginning from the original data of the photogrammetrical survey carried out in the 1950s. This produced a reflection on “Image Based” methods and modeling techniques, comparing strict 3d digital photogrammetry with the latest Structure From Motion (SFM systems. The topographic survey data, the original photogrammetric stereo couples, the points coordinates and their representation in contour lines, allowed to obtain a model of the monument in his configuration before the moving of the temples. The impossibility to carry out a direct survey led to touristic shots to create SFM models to use for geometric comparisons.

    Hydrogeochemical and geoelectrical resistivity investigations were carried out to assess the origin and characteristics of a brackish groundwater in Abu Madi coastal area. Twenty six surface water, shallow and deep groundwater samples were collected and analyzed for various ionic concentrations as well as oxygen and hydrogen stable isotopic contents. In addition, a total of 20 vertical electrical sounding sites were conducted to investigate layers' thicknesses, resistivities, and to detect the water-bearing layers. Then, 2-D Electrical Resistivity Tomography (ERT) along two profiles in the study area was conducted to get information about the surface water effect on recharge. The stable isotopic composition and the chloride concentrations strongly suggest that the deep groundwater in Abu Madi area is dominated by inland freshwater with a minor seawater component. This groundwater was recharged during the first and the third Holocene humid climatic cycles where the sea surface was about 125 and 25 m below the current sea level, respectively. The brackish nature and higher piezometric surface of the groundwater, as well as the occurrence of vertical low-salinity seawater zone in front of the study area, support the possibility of submarine groundwater discharge. The geoelectrical resistivity surveying, on the other hand, revealed a number of geoelectrical groundwater-bearing layers. The main water-bearing layer in the study area is represented by the sixth geoelectrical layer, which has relatively high resistivity and a considerable thickness being consistent with the hydrogeochemical observations. ERT results point to the presence of shallow water-bearing layers recharged from the surface water drains with low resistivity and surface rain water of moderate resistivity. Results from the hydrogeochemical analyses and the different hydrogeological data are consistent with the high resistivity values of this geoelectrical layer. However, the overall high specific

    Full Text Available The present work aimed to obtain precise data on the catch of the purse seine net operating at daytime from sunrise till noon in Abu Qir Bay during 1997 and 1998. Sardine, anchovy, mullet and rabbitfish were recorded as the main target fish groups. Twenty-seven species were recorded as by-catch species. Catch per unit effort was estimated to be 93 kg/day/boat. The percentage of each target species in the catch and its length frequency distribution were presented. The length range of by-catch species and the season of catch were recorded. Daytime purse seine in Abu Qir Bay is an effective method but should regulated by directing the fishing to deeper waters outside the bay rather than the inshore coastal area to conserve many economic species of this important fishery.

    Full Text Available The Abu Rushied area, situated in the South Eastern Desert of Egypt is a distinctive occurrence of economically important rare-metal mineralization where the host rocks are represented by granitic gneisses. Correspondingly, mineralogical and geochemical investigation of pegmatites pockets scattered within Abu Rusheid granitic gneisses revealed the presence of Hf-zircon, ferrocolumbite and uranyl silicate minerals (uranophane and kasolite. Electronmicroprobe analyses revealed the presence of Nb-Ta multioxide minerals (ishikawaite, uranopyrochlore, and fergusonite, uraninite, thorite and cassiterite as numerous inclusions in the recorded Hf-zircon and ferrocolumbite minerals.Abu Rusheid pegmatites are found as small and large bodies that occur as simple and complex (zoned pegmatites.Abu Rusheid rare-metal pegmatites occur as steeply dipping bodies of variable size, ranging from 1 to 5 m in width and 10 to 50 m in length. The zoned pegmatites are composed of wall zone of coarser granitic gneisses, intermediated zone of K-feldspar and pocket of mica (muscovite and biotite, and core of quartz and pocket ofmica with lenses of rare metals.The zircon is of bipyramidal to typical octahedral form and short prisms. Because the zircon of the investigated Abu Rushied pegmatite frequently contains hafnium in amounts ranging between 2.31 and 11.11%, the studied zircon was designated as Hf-rich zircon. This zircon commonly exhibits a normal zoning with rims consistentlyhigher in Hf than cores. The bright areas in the crystal either in core or rim showed a remarkable enrichment in hafnium content (8.83–11.11% with respect to the dark zones (3.19%. The investigated ferroclumbite commonly exhibits zoning; the dark zone is low in the Ta and U but the light zone is enriched in Ta (13% and U (1%. EMPAanalyses indicate the chemical composition of ishikawaite with U ranging from 0.68 to 0.79 per formula unit.Uranopyrochlore species has dominant uranium in the A

  11. Distribution of REE in shales overlying the Abu Tartur phosphorite deposit, Western Desert, Egypt

    International Nuclear Information System (INIS)

    The phosphorite deposit of Abu-Tartur plateau, Western Desert, Egypt is one of the largest phosphorite deposits of the world. Previous investigations had revealed that these deposits contain appreciable amounts of rare earth elements (REE) reaching up to 2000 ppm. The distribution pattern of REE indicate terrestrial origin, whereas the phosphorites are of marine origin. This situation suggests that the REE have been remobilized and incorporated into the phosphorites postdepositionally. For this reason it was found of interest to investigate the REE distribution within the overlying shales and their association with different minerals. Samples from the phosphorites and overlying shales have been provided by the Geological Survey and Mining Authority, Egypt. Both ICP-AES and ICP-MS techniques were used for the quantitative determination of the individual REE. Normalized distribution patterns prove that REE in both phosphorites and shales are of terrestrial origin. The vertical distribution of REE in m% within the overlying shales and the abnormally high concentrations of REE in this formation relative to their normal background values in addition to the association of REE with aluminum silicate minerals and not with apatite (which is found in very low concentrations) all suggest that the provenance of REE is the overlying shales. More detailed studies have to be carried out to verify this finding. (orig.)

    Full Text Available The serpulid polychaete Spirobranchus tetraceros of Red Sea / Indo-pacific origin, recently has succeeded to establish a foothold in Alexandria Mediterranean waters. Worms were monthly scraped from submerged iron substrates at Abu Kir Bay during the period December 2000 – November 2001. Both light and TEM were used to study gametogenesis and time of spawning of S. tetraceros.Gametogenesis was asynchronous and oogenesis could be divided into two previtellogenic, two vitellogenic and a spawning stage. Oocyte development took about 8 months, from October to June. Spawning occurred from late May - early June until October. Thus S. tetraceros is a long period spawner. The maximum diameter of ripe oocyte is 78 mm. The spermatogenic phase could be divided into three stages: spermatogonia, spermatocytes and spermatids (including spermatozoa. The duration of sperm development took about 8 months. Spermatocytes persist from October to March. By March the sperms grew rapidly until they became spermatozoa in May. The sperm could be considered ect-aquasperm with regard to its fertilization biology.

    Abu Hamed, Sudan, the northernmost location of onchocerciasis in the world, began community-directed treatment with ivermectin (CDTI) in 1998, with annual treatments enhanced to semiannual in 2007. We assessed the status of the parasite transmission in 2011 entomologically, parasitologically, and serologically. O-150 pool screening showed no parasite DNA in 17,537 black flies collected in 2011 (95% confidence interval upper limit [95% CI UL] = 0.023). Skin microfilariae, nodules, and signs of skin disease were absent in 536 individuals in seven local communities. Similarly, no evidence of Onchocerca volvulus Ov16 antibodies was found in 6,756 school children ≤ 10 years (95% CI UL = 0.03%). Because this assessment of the focus meets the 2001 World Health Organization (WHO) criteria for interrupted transmission, treatment was halted in 2012, and a post-treatment surveillance period was initiated in anticipation of declaration of disease elimination in this area. We provide the first evidence in East Africa that long-term CDTI alone can interrupt transmission of onchocerciasis. PMID:23690554

    Full Text Available In his discussion of Dante’s Inferno, Edward Said writes that “Maometto” or Mohammed occupies the eighth circle in the nine circles of Hell, belonging to “a rigid hierarchy of evils.”  According to Said, “Maometto” is “endlessly being cleft in two from his chin to his anus,” a punishment in Dante’s belief is well deserved because of Maometto’s sensuality and “pretensions to theological eminence.”  Such graphic description of torment evokes scenes of torture we have of late witnessed in Abu Ghreib and Guantanamo.  Prisoners, not only, were subjected to physical abuse but were also subjected to acts of sexual perversion as was revealed by the photos.  Furthermore, the latter showed those who partook in these actions seemed to be enjoying the power that the exercise of torture gave them.  Robert J.C. Young states that Colonialism “was not only a machine of war … but also a desiring machine.”  This poses the question as to whether torture does allow for the enactment of repressed desire by allowing it to surface by providing it with a venue in which it becomes acceptable.  Moreover, does Colonialism in its previous or in its current form, only sustain itself fundamentally through constant violence, of which perversion is a vital component as these practices are playing into the repertoire of the evil East, or is the perversion an extension of a suppressed Oedipus complex?

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

    A regional compilation of published and unpublished gravity data for Central Africa is presented and reveals the presence of a major rift system, called here, the Central African Rift System. It is proposed that the junction area between the Ngaoundere and Abu Gabra rift arms in Western Sudan forms an incipient intraplate, triple-junction with the as yet unfractured, but domally uplifted and volcanically active, Darfur swell. It is only the Darfur swell that shows any similarities to the uplift and rift history of East Africa. The other two rifts arms are considered to be structurally similar to the early stages of passive margin development and thus reflect more closely the initial processes of continental fragmentation than the structures associated with rifting in East Africa.

    Directory of Open Access Journals (Sweden)

    Henry A. Giroux

    2010-05-01

    Full Text Available How might education be used to question the common sense of the war on terrorism or to rouse citizens to challenge the social, political, and cultural conditions that led to the horrible events of Abu Ghraib? Just as crucially, we must ponder the limits of education. Is there a point where extreme conditions shortcircuit our moral instincts and ability to think and act rationally? If this is the case, what responsibility do we have to challenge the reckless violence-as-fi rst-resort ethos of the Bush administration? Such questions extend beyond the events of Abu Ghraib, but, at the same time, Abu Ghraib provides an opportunity to connect the sadistic treatment of Iraqi prisoners to the task of redefi ning pedagogy as an ethical practice, the sites in which pedagogy takes place, and the consequences of pedagogy to rethinking the meaning of politics in the twenty-fi rst century. In order to confront the pedagogical and political challenges arising from the reality of Abu Ghraib, I want to revisit a classic essay by Theodor Adorno in which he tries to grapple with the relationship between education and morality in light of the horrors of Auschwitz. Keywords: Education. Adorno. Auschwitz. Abu Ghraib. Como pode a educação ser usada para questionar o senso comum da guerra ao terrorismo ou para insuflar os cidadãos a desafi ar as condições sociais, políticas e culturais que conduziram aos eventos horríveis de abusos contra prisioneiros iraquianos na prisão americana de Abu Ghraib? Só assim, de modo crucial, podemos ponderar os limites da educação. Até que ponto as condições extremas causam curto-circuito em nossos instintos morais e em nossa capacidade de pensar e agir racionalmente? Se for esse o caso, qual nossa responsabilidade em desafi ar o etos imprudente da “violência como primeiro recurso” da administração de Bush? Tais questões estendem-se além dos eventos de Abu Ghraib, mas, ao mesmo tempo, Abu Ghraib fornece uma

    The Sufyan Sag is one of the low-exploration areas in the Muglad Basin (Sudan), and hydrocarbon potential evaluation of source rocks is the basis for its further exploration. The Abu Gabra Formation consisting of three members (AG3, AG2 and AG1 from bottom to top) was thought to be the main source rock formation, but detailed studies on its petroleum geology and geochemical characteristics are still insufficient. Through systematic analysis on distribution, organic matter abundance, organic matter type, organic matter maturity and characteristics of hydrocarbon generation and expulsion of the source rocks from the Abu Gabra Formation, the main source rock members were determined and the petroleum resource extent was estimated in the study area. The results show that dark mudstones are the thickest in the AG2 member while the thinnest in the AG1 member, and the thickness of the AG3 dark mudstone is not small either. The AG3 member have developed good-excellent source rock mainly with Type I kerogen. In the Southern Sub-sag, the AG3 source rock began to generate hydrocarbons in the middle period of Bentiu. In the early period of Darfur, it reached the hydrocarbon generation and expulsion peak. It is in late mature stage currently. The AG2 member developed good-excellent source rock mainly with Types II1 and I kerogen, and has lower organic matter abundance than the AG3 member. In the Southern Sub-sag, the AG2 source rock began to generate hydrocarbons in the late period of Bentiu. In the late period of Darfur, it reached the peak of hydrocarbon generation and its expulsion. It is in middle mature stage currently. The AG1 member developed fair-good source rock mainly with Types II and III kerogen. Throughout the geological evolution history, the AG1 source rock has no effective hydrocarbon generation or expulsion processes. Combined with basin modeling results, we have concluded that the AG3 and AG2 members are the main source rock layers and the Southern Sub-sag is

    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.

    Full Text Available Variations in protein, carbohydrate, lipid, ash, moisture, fatty acid and aminoacid contents of the seaweeds Ulva lactuca Linnaeus (Chlorophyta,Jania rubens (Linnaeus J.V. Lamouroux and Pterocladia capillacea (S.G. Gmelin Bornet(Rhodophyta were studied seasonally from spring to autumn 2010. The seaweeds were collected from a rocky site near Boughaz El-Maadya on the coast of Abu Qir Bay east of Alexandria, Egypt. Remarkable seasonal variations were recorded in the levels of the studied parameters in the three species. Pterocladia capillacea was characterized by the highest protein andcarbohydrate content throughout the different seasons, whereas Ulva lactuca contained more lipids (4.09 ± 0.2% than J. rubens and P. capillacea. The highest total fatty acids were recorded in J. rubens during the three seasons, while saturated fatty acids were predominant in P. capillacea during spring. This is due mainly to the presence of palmitic acid(C16:0, which made up 74.3% of the saturated fatty acids. The highest level of polyunsaturated fatty acids (PUFA in these algae was measured in J. rubens; DHA (22:6ω3 was the main acid, making up 26.4% of the total fatty acids especiallyduring summer. Proline was the major component of the amino acids in the three algal species, with maximum amounts in U. lactuca.

    Organic-rich sediments within the Abu Gabra Formation from three wells in the Great Moga oilfield were analyzed using organic geochemistry and organic petrology. The analyzed samples generally contain more than 2.0 wt.% TOC and have a very good to excellent hydrocarbon generative potential. This is supported by high bitumen extract and hydrocarbon (HCs) yields with values exceeding 4000 and 2000 ppm, respectively. The Abu Gabra also have moderate to high hydrogen index (HI) values of 287-865 mg HC/g TOC and large amounts of amorphous organic matter and alginite, consistent with oil-prone Types I and Type II kerogen. Vitrinite reflectance (0.59-0.72) %Ro and pyrolysis Tmax (430-438 °C) indicate an early oil window stage. This is supported by bitumen/TOC ratios (0.04-0.09) and biomarker thermal maturity parameters with equilibrium C32 homohopane 22S/(22S + 22R) ratios (0.50-58), moretane/hopane (0.11-018) and C29ββ/(ββ + αα) (0.53-0.73) and 20S/(20S + 20R) ratios (0.26-0.48). The biomarkers are characterized by a dominance of low to medium molecular weight n-alkane compounds with significant waxy alkanes (n-C25-n-C34), moderately high Pr/Ph ratios (1.17-2.51), high abundance of C27 regular steranes, high C27/C29 regular sterane ratios, the presence of tricyclic terpanes and relatively low sterane/hopane ratios. These data indicate that the organic-rich sediments of the Abu Gabra Formation contain a mixture of aquatic (algal and bacterial) and terrigenous organic matter, deposited in a lacustrine environment and preserved under suboxic conditions.

    We report the detection of high polarization in the first detailed optical linear polarization measurements on the BL Lac object CGRaBS J0211+1051, which flared in γ-rays on 2011 January 23 as reported by Fermi. The observations were made during 2011 January 30-February 3 using a photo-polarimeter mounted at the 1.2 m telescope of Mount Abu Infrared Observatory. CGRaBS J0211+1051 was detected to have a ~21.05% ± 0.41% degree of polarization (DP) with a steady position angle (P.A.) at 43° on 2011 January 30. During January 31 and February 1, while polarization shows some variation, the P.A. remained steady through the night. Several polarization flashes occurred during February 2 and 3 resulting in changes in the DP by more than 4% at short timescales (~17-45 minutes). The intra-night variability shown by the source appears to be related to the turbulence in the relativistic jet. A mild wavelength dependence of polarization is not ruled out during the nights of February 2 and 3. The source exhibited significant inter-night variations in the DP (changing by about 2%-9%) and P.A. (changing by 2°-22°) during the five nights of observations. A sudden change in the P.A. accompanied by a rise in the DP could be indicative of the fresh injection of plasma in the jet. The detection of a high and variable DP suggests that the source is a low-energy peaked blazar.

  11. Effect of cyclone Nilofar on mesospheric wave dynamics as inferred from optical nightglow observations from Mount Abu, India

    Singh, Ravindra P.; Pallamraju, Duggirala

    2016-06-01

    Mesospheric nightglow intensities at three emissions (O2(0-1), OH(6-2) bands, and Na(589.3 nm)) from a low-latitude location, Gurushikhar, Mount Abu (24.6°N, 72.8°E), in India, showed similar wave features on 26 October 2014 with a common periodicity of around 4 h. A convective activity due to the cyclone Nilofar, which had developed in the Arabian Sea during 25-31 October 2014, was found to be the source as this too showed a gravity wave period coherent with that of the mesospheric emissions on the 26th. The periodicities at the source region were obtained using outgoing longwave radiation fluxes (derived from Kalpana-1 satellite) which were used as a tracer of tropospheric activity. Cyclone Nilofar had two centers located at a distance of 1103 and 1665 km from the observational station. From the phase offset in time between residuals of O2 and OH emission intensities and the observed common periodicity the vertical phase speed and wavelength have been found to be 1.13 ms-1 and 16.47 km. From the wavelet analyses it is seen that the travel time of the wave from the convection region to O2 emission height was around 8.1 h. From these observations the horizontal phase speed and wavelength of the wave in the mesosphere were calculated to be 37.8 ms-1 and 553 km. These results thus provide not only unambiguous evidence on the vertical coupling of atmospheres engendered by the tropical cyclone Nilofar but also the characteristics of waves that exist during such cyclonic events.

  12. New ceramic data from East Kalimantan : the cord-marked and red-slipped sherds of Liang Abu's layer 2 and Kalimantan's potter chronology

    International Nuclear Information System (INIS)

    Archaeological research in the Liang Abu rock shelter (East Kalimantan) led to the discovery and analysis of a pottery assemblage including red-slipped, cord-marked and incised pottery sherds, radiocarbon dated to 1672 ± 21 BP and 1524 ± 22 BP. In order to discuss our findings we undertake a reappraisal of the pottery material and associated radiocarbon dates from archaeological sites on Borneo Island, which provide us with an appropriate framework for a comparative analysis. This allows us to to include the inland region of Kalimantan in the technological network of Neolithic Island South East Asia. (author)

  14. "Islam" as the national identity for the formation of Pakistan: the political thought of Muhammad Iqbal and Abu'l 'Ala Mawdudi

    2014-06-01

    Full Text Available In 1930, Muhammad Iqbal (1877-1938 devised for the first time the creation of a separate state for the Indian Muslims, for whom, according to him, the main formative force through History had been Islam. Although predicated upon secular ideologies, the Pakistan movement was able to mobilize the masses only by appealing to Islam. Nationalism became dependent on Islam and, as a result, politicized the faith. A number of Muslim religious and communal organizations pointed to the importance of promoting Muslim nationalism, political consciousness and communal interests. As the creation of Pakistan became more and more likely, Abu'l 'Ala Mawdudi (1903-1979 increased his attacks on the Muslim League, objecting to the idea of Muslim nationalism because it would exclude Islam from India. The increasingly communal character of the Indian politics of the time, and the appeal made to religious symbols in the formulation of new political alliances and programmes by various Muslim groups as well as Muslim League leaders, created a climate in which Mawdudi's theological discourse found understanding and relevance. This paper, using especially the political thought of Muhammad Iqbal and Abu'l 'Ala Mawdudi, analyses how Islam was used to justify a separate state for the Indian Muslims, and the impacts on and challengesto the political process and its evolution, at the same time that it concludes that "Islam", as a political symbol, can have many forms according to the ideas previously held by those who use it.

  15. 3D Geometric Modeling of the Abu Madi Reservoirs and Its Implication on the Gas Development in Baltim Area (Offshore Nile Delta, Egypt

    Directory of Open Access Journals (Sweden)

    Mohamed I. Abdel-Fattah

    2015-01-01

    Full Text Available 3D geometric modeling has received renewed attention recently, in the context of visual scene understanding. The reservoir geometry of the Baltim fields is described by significant elements, such as thickness, depth maps, and fault planes, resulting from an interpretation based on seismic and well data. Uncertainties affect these elements throughout the entire interpretation process. They have some bearing on the geometric shape and subsequently on the gross reservoir volume (GRV of the fields. This uncertainty on GRV also impacts volumes of hydrocarbons in place, reserves, and production profiles. Thus, the assessment of geometrical uncertainties is an essential first step in a field study for evaluation, development, and optimization purposes. Seismic data are best integrated with well and reservoir information. A 3D geometric model of the Late Messinian Abu Madi reservoirs in the time and depth domain is used to investigate the influence of the reservoir geometry on the gas entrapment. Important conceptual conclusions about the reservoir system behavior are obtained using this model. The results show that the reservoir shape influences the seismic response of the incised Abu Madi Paleovalley, making it necessary to account for 3D effects in order to obtain accurate results.

  17. Technical feasibility of a seabed gallery seawater intake at Ras Abu Ali Island, Arabian Gulf, Saudi Arabia

    KAUST Repository

    Rachman, Rinaldi

    2014-07-23

    Open-ocean intake systems require extensive and advanced pretreatment unit operation to produce feed water with low membrane fouling potential in seawater reverse osmosis (SWRO) facilities. Alternatively, subsurface intake systems tend to produce high quality raw seawater even before pretreatment. Subsurface intakes extract seawater indirectly through the geological structure of shoreline or nearshore sediments. Water percolation through geological units provides physical and biological treatment, so that the raw seawater is microbiologically stable with relatively low particulate and organics content. Overall, utilization of subsurface intakes will reduce the intensity of pretreatment, which reduces operating cost, lowers chemical and energy consumption, and reduces environmental impacts. An important aspect in the feasibility of a subsurface intake is the compatibility of the local geological environment. In this study, a field investigation was conducted at Ras Abu Ali Island in the Arabian Gulf. This location currently contains an of existing oil company facilities and a proposed governmental marine fish hatchery facility. Recreational, commercial, and domestic potable water uses require the need to use the SWRO process to meet demands. Characterization of the shoreline and marine offshore bottom were performed as well as observation of tidal fluctuations and wave heights. A specific grid area was chosen where 35 sediment samples were collected from the seabed floor for laboratory analysis of grain size distribution, sediment porosity, and hydraulic conductivity. Onsite observation showed that the marine bottom has a low slope creating a wide intertidal area. The lowest tidal zone is more than 150 m from the shoreline defining a far seaward boundary for the intake construction point. A relatively thin layer of mixed-type sediment (carbonate and siliciclastic) covers the marine hardground bottom. The unlithified bottom sediment contains a low mud percentage

  18. THE GENIUS LOCI AT THE GREAT TEMPLE OF ABU SIMBEL: HERMENEUTIC READING IN THE ARCHITECTURAL LANGUAGE OF ANCIENT EGYPTIAN TEMPLES OF RAMSES II IN NUBIA

    Directory of Open Access Journals (Sweden)

    Nelly Ramzy

    2015-06-01

    Full Text Available Archaeologists have long wondered about the Temple of Abu Simbel: its location within the Nubian territory far from major Egyptian cities, and its unique design. Utilizing the hermeneutic process of understanding the whole from the parts and then situating the whole within a bigger whole (context, this study is a trial to arrive at a better interpretation of this monument. Drawing on the characteristic analysis of the temple's Genius Loci as developed by Norberg-Schulz, as well as on Heidegger's anticipatory fore-structures, the study goes on to show that both of the location and the unique structure of the temple were the outcome of political and conceptual aspects of the period, more than being a religious tradition. Reaching this conclusion, another goal had been achieved, where the validity of hermeneutic analyses as a useful tool for discovering new dimensions about historical monuments and archaeological sites had been attested.

    2006-07-15

    Soil radon concentration levels in Deir Abu-Said District, Irbid-Jordan were measured using CR-39 track detectors in both summer and winter at several depths over six geological formations. Seasonal variations of soil radon were measured at five depths (10, 25, 50, 75 and 100cm). At a depth of 100cm; soil radon concentration levels, in summer, range from 6.85kBqm{sup -3} for Muwaqqar Chalky-Marl (MCM) to 35.5kBqm{sup -3} for Al-Hisa Phosphatic (AHP) Limestone, while in winter the range is between 4.01 and 24.6kBqm{sup -3}, respectively. The highest values of soil radon concentration obtained are found for AHP in both seasons at all depths. This is related to the high content of uranium of this geological formation. As expected, our data show an increase of soil radon concentration levels with depth.

    2015-12-01

    Full Text Available The objective of this study is to assess the organic material for petroleum potential and characterize the relationships between organic material, thermal maturity, and the depositional environments. This is done using “14” samples from the shales of the Dakhla and Duwi formations in Abu Tartur area. The samples have been analyzed using the geochemical method of Rock–Eval pyrolysis. The analysis shows that the total organic carbon content lies between 0.56 and 1.96 wt%. It also shows that kerogen is a mixture of type II and III that is dominant, and is deposited in the shallow and restricted marine environment under prevailing reducing conditions. This type of kerogen is prone to oil and oil/gas production. The geochemical diagrams show that all the studied samples have good thermal maturation. The Dakhla and Duwi formations which have been divided into all zones are mature (have Tmax over 435 °C, and have organic carbon content located at the oil window (Tmax between 435 and 443 °C.

  5. Magmatic and solid state structures of the Abu Ziran pluton: Deciphering transition from thrusting to extension in the Eastern Desert of Egypt

    Science.gov (United States)

    Fritz, Harald; Loizenbauer, Jürgen; Wallbrecher, Eckart

    2014-11-01

    The 606 Ma old Abu Ziran granite of the Eastern Desert of Egypt intruded the southern margin of the Meatiq dome in a sinistral shear extensional setting. Its emplacement was enabled by a system of NW-trending sinistral shears, related Riedel shears and N-S extensional shear zones and faults. Magmatic flow was east-directed and controlled by Riedel shears that progressively rotated to an orientation favourable for extension. Strain markers that document magmatic flow show eastward decreasing strain together with strain increase from pluton centre to margins. This is explained by Newtonian flow between non-parallel plates and differences in flow velocities across the pluton. Solid state fabrics including shear fabrics, orientation of late magmatic dykes and quartz tension gashes, together with quartz C-axes distributions, document southward extensional shear within the solidified pluton and adjacent host rocks. Extensional shear is correlated with exhumation of the Meatiq dome coeval and soon after pluton solidification (585 Ma). Pressure temperature evolutionary paths, derived from fluid inclusions, show a clockwise path with exhumation by isothermal decompression in the Meatiq dome. By contrast, the overlying volcanosedimentary nappes experienced an anti-clockwise path released by temperature rise due to pluton emplacement followed by isobaric cooling. Quartz fabrics indicate high-temperature coaxial N-S flow in the northern Meatiq dome and lower-temperature, non-coaxial southward flow within the overlaying superficial nappe. This is explained by the exhumation process itself that progressively localised into simple shear domains when rocks approached higher crustal levels. Late extension at ca. 580 Ma was pure shear dominated and resulted in reversal of shear, now dextral, in the western Meatiq shear zone.

    An atmospheric science laboratory was set up at Gurushikhar, in the campus of PRL's Infrared observatory, in 1994. A variety of scientific instruments were housed in the atmospheric science laboratory to explore the Earth's ionosphere and neutral atmosphere. A powerful Nd-YAG laser based Lidar, a multi-wavelength all sky imaging system, Day-night-airglow photometer/spectrometer and a proton precession magnetometer are in operation along with a surface ozone sampler, a carbon mono-oxide analyzer and a UV radiometer (measures solar ultraviolet irradiance between 280 and 320 nm). This article highlights the neutral density and temperature measurements by the lidar as well as Atmospheric/Ionospheric parameters derived by other instruments.

  18. Apuntes hagiográficos e iconográficos sobre un modelo de santidad militar: Mercurio-Abu Seifein, el mártir de las dos espadas

    Full Text Available In this paper we propose a short analysis of the iconographical canon related to Abu Seifein, best known as Saint Mercurius, a military martyr of the III rd. century, focusing specially on the saint’s weapons just as this appears in the Western and Eastern iconography. The epithet under with he is known in the Coptic sphere makes reference to the two swords, the human and the divine one, with which he is represented in the act of killing the emperor Julian the Apostate. There are, however, some other iconographical variants, very poor in details as far as the weapons and the stratiotike esthes are concerned, if we face them up to the contemporary military Byzantine treatises.

    En el presente artículo proponemos un breve análisis del canon figurativo relativo a Abu Seifein, más conocido como San Mercurio, un mártir militar del siglo III, haciendo especial hincapié en las armas del santo tal como aparecen en la iconografía oriental y occidental. El epíteto con el que se le conoce en ámbito copto hace referencia a las dos espadas, una humana, la otra divina, con las que es representado en el acto de acabar con la vida de Juliano, el emperador apóstata. Sin embargo, se evidencian otras variantes iconológicas, muy pobres en detalles en lo que se refiere a las armas y a la stratiotike esthes si las comparamos con los tratados militares bizantinos contemporáneos.

    Full Text Available Up until the Crusades, it was al-Rūm who were universally seen by Arab writers and Arab poets in particular as the Other par excellence. Nowhere is this more conspicuous than in the sub-genre of Al-Rūmiyyat (poems about the Byzantines, namely as found in the Rūmiyyat of Abu Firas al-Hamdani(d.968, and in the poetic responses of al-Qaffal(d. 946 and Ibn Hazm(d. 1064 to what was described by several medieval Muslim chronicles as Al-Qasida al-Arminiyya al-Malʿuna (The Armenian Cursed Ode. By exploring the forgotten views of the Byzantines in medieval Arabic poetry, this article purports to demonstrate that contrary to the impression left after reading Edward Said’s groundbreaking Orientalism: Western Conceptions of the Orient (1978 and other postcolonial studies, Orientals have not existed solely to be ‘orientalized’. Perhaps even before this came to be so, they too had ‘occidentalized’ their Euro-Christian Other(s in a way that mirrored in reverse the subject/object relationship described as Orientalism.

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

    Although competency-based medical education has become the standard for physician training in the West, many developing countries have not yet adopted competency-based training. In 2009 in the United Arab Emirates, the government regulatory and operational authorities for healthcare in Abu Dhabi mandated a wide-scale reform of the emirate's postgraduate residency programs to the competency-based framework of the newly formed Accreditation Council for Graduate Medical Education-International (ACGME-I). This article briefly describes the rationale for competency-based medical education and provides an overview of the transition from traditional, time-based residency training to competency-based postgraduate medical education for the Pediatrics residency programs in Abu Dhabi. We will provide data on the initial impact of this transition on resident performance and patient outcomes in a Pediatrics residency program in an academic medical center in the United Arab Emirates.

    Coral reefs of the United Arab Emirates were once extensive, but have declined dramatically in recent decades. Marine management and policy have been hampered by outdated and inaccurate habitat maps and habitat quality information. We combined existing recent datasets with our newly mapped coral habitats to provide a current assessment of nation-wide extent, and performed quantitative surveys of communities at 23 sites to assess coral cover and composition. Over 132 km(2) of coral habitat was mapped, averaging 28.6 ± 3.8% live coral cover at surveyed sites. In the Arabian Gulf low cover, low richness Porites dominated communities characterized western Abu Dhabi, while reefs northeast of Abu Dhabi city generally contained higher richness and cover, and were dominated by merulinids (formerly faviids). Distinct communities occur in the Sea of Oman, where cover and richness were low. We provide management recommendations to enhance conservation of vulnerable coral reefs in the UAE.

    Al-Ain is the second largest city in the Emirate of Abu Dhabi and the third in the UAE. Currently, desalination plants are the only source of drinking water in the city with an average daily supply of 170 MIG. Recently, Abu Dhabi Urban Planning Council (UPC) released Al-Ain 2030 Plan. Projects suggested in this plan, over and above the expected natural population growth, will certainly put additional stress on the water resources in the city. Therefore, Al-Ain city seems to be in urgent need for an integrated water resources management strategy towards achieving sustainable development. This strategy will contain three main components; namely, a Water Demand Forecasting Model (WDFM), a Water Budget Model (WBM), and a Water Resources Optimization Model (WROM). The main aim of this paper is to present the WBM that estimates all inflows and outflows to assess water resources sustainability in the city.

  3. Solar radiation for sea-water desalination and electric power generation via vacuum solar collectors

    International Nuclear Information System (INIS)

    The present report concerns the energetic potential of vacuum solar which are rather versatile and efficient devices for converting solar energy into thermal energy. Two main energetic applications have been analysed: the first one for a solar sea water desalination plant which has been operated in Abu Dhabi for the past ten years, the other for a conceptual solar thermoelectric-power plant having a fair thermodynamic efficiency (15-20%). A simple technology for the manufacture of vacuum solar collectors in a standard mechanical shop is being developed in collaboration between ENEL Sp A (DSR-CRIS, Milano) and WED (Abu Dhabi). Such technology should have an important economy-saving potential per se and would also make repair and substitution operations simple enough for the actual operators of the vacuum solar collector system without any need of external assistance. The technic-operative-economical features of the Abu Dhabi solar desalination plant suggest that the use novel simplified vacuum solar collectors could have a considerable technic economical potential. The analysis of the conceptual solar thermo-electric-power plant focuses on its general layout and singles out key technological issues which ought to be addressed in an overall feasibility study. 5 figs., 3 tabs

    Full Text Available Pernyataan bahwa alam ini muncul bersamaan dengan Zat Tuhan berimplikasi kepada adanya persaingan antara alam dengan Tuhan dalam eksistensinya. Benarkah Tuhan yang menciptakan alam? Jika benar, kapan Tuhan mulai menciptakannya? Dan mengapa Tuhan tidak menciptakannya pada waktu yang lain? Di antara para Filsuf Muslim pun terdapat ragam pendapat yang jika kita salah dalam memahaminya, akan menyebabkan seseorang mengingkari eksistensi Tuhan. Salah satu pendapat yang cukup menarik untuk dicermati adalah konsep alam menurut al-Ghazali. Ia merupakan salah satu filosof dan teolog Muslim yang terkenal yang dengan kedalaman ilmunya membuat ia digelar sebagai hujjah al-Islam. Makalah ini akan membahas konsepsi al-Ghazali tentang alam yang tersusun terutama dari kritik al-Ghazali terhadap argumentasi para filsuf berupa argumen Tarjih dan Murajjih, argumen Taqaddum Zamani, argumentasi al-Imkan, serta argumen materi. Melalui makalah sederhana ini akan dipaparkan pemikiran al-Ghazali mengenai alam, sekaligus membantah beberapa konsep para filosof barat dengan nas-nas yang otentik.

    The UAE Offsets Group Office (UOG), responsible for developing alliances between the private sector of the United Arab Emirates and international companies, announced on 1. March that a strategic partnership has been established with Enron and TotalFina Elf for implementation of the Dolphin Project, one of the largest world-wide integrated initiatives in the energy sector. The First objective of this partnership, the life of which has been fixed at 25 years, will be to develop the Dolphin infrastructure through a new gas pipeline with a capacity of 85 million cu.m of gas per day, linking Qatar to Abu Dhabi and the Sultanate of Oman. This initial phase will be based on the development of activities all along the gas line. The Project Development Agreement (PDA) concluded by the UOG, Enron and Elf also includes the exploitation of other opportunities in the Gulf countries and the region. The UOG will hold a majority share of 51% in this partnership, the remaining 49% being shared equally between Enron and Elf. Construction work on the gas pipeline and the various installations upstream of Qatar should be quickly put in hand. A series of preliminary agreements concluded with the government authorities of Qatar, Abu Dhabi, Dubai, Oman and Pakistan, relating to the procurement and sale of gas, has enabled the implementation of the geographical and political organisation necessary to realize the Dolphin Project.

    2013-06-01

    Many nations are struggling with the design, implementation, and ongoing improvement of health care systems to meet the needs of their citizens. In the United Arab Emirates, a small nation with vast wealth, the lives of average citizens have evolved from a harsh, nomadic existence to enjoyment of the comforts of modern life. Substantial progress has been made in the provision of education, housing, health, employment, and other forms of social advancement. Having covered these basic needs, the government of Abu Dhabi, United Arab Emirates, is responding to the challenge of developing a comprehensive health system to serve the needs of its citizens, including restructuring the nation's graduate medical education (GME) system. We describe how Abu Dhabi is establishing GME policies and infrastructure to develop and support a comprehensive health care system, while also being responsive to population health needs. We review recent progress in developing a systematic approach for developing GME infrastructure in this small emirate, and discuss how the process of designing a GME system to meet the needs of Emirati citizens has benefited from the experience of "Western" nations. We also examine the challenges we encountered in this process and the solutions adopted, adapted, or specifically developed to meet local needs. We conclude by highlighting how our experience "at the GME drawing board" reflects the challenges encountered by scholars, administrators, and policymakers in nations around the world as they seek to coordinate health care and GME resources to ensure care for populations.

  3. Life-Cycle Analysis of Building Retrofits at the Urban Scale—A Case Study in United Arab Emirates

    Directory of Open Access Journals (Sweden)

    Afshin Afshari

    2014-01-01

    Full Text Available A consensus is forming among experts that the best way to achieve emissions’ reduction in the near and mid-term is increasing the demand-side energy efficiency—this is especially true in developing countries where the potential for demand reduction is significant and achievable at relatively lower cost. Enhanced energy efficiency also reduces energy costs and can result in a financial benefit to end-users, if the life-cycle value of energy savings offsets the upfront cost of implementing the measure. At the same time, reducing energy demand translates into lower pull for fossil fuel import and supply/distribution capacity expansion. An ideal candidate for the implementation of demand-side energy efficiency measures is the building sector, since it contributes to a large extent to the total amount of greenhouse gases (GHGs emitted worldwide. In most developing countries, the contribution of the building sector to the total national GHG emissions is significantly higher than the worldwide average. This is in part due to the lower level of industrial activity. Other drivers of the high emissions of the building sector are the inefficiency of the envelope and technical systems of the existing buildings, as well as harsh climatic conditions requiring the use of energy intensive air-conditioning equipment. The United Arab Emirates (UAE currently have the highest ecological footprint per capita in the world. The Emirate of Abu Dhabi, the focus of this study, can be expected to have a footprint that is even higher, being the largest economy and the major oil producer among the seven Emirates. In addition to the environmental consequences of unrestrained energy consumption, the fact that energy prices are heavily subsidized in Abu Dhabi results in a significant financial burden for the government. In the UAE and the Emirate of Abu Dhabi, the air-conditioning load in buildings is the ideal target for demand-side management because it constitutes more

    This paper introduces afforestation examples for desert reforestation in the United Arab Emirates. The afforestation in this country was initiated for the erosion control of arterial road in Abu Dhabi. Up to 1992, total afforestation area was expanded to 29,200ha. In the initial stage, kinds of trees were mainly introduced species, such as Eucalyptus, Acasias, Casurinas, and Prosopis. Afterward, they were changed to the local variety with high drought resistance, high salt water resistance, and low water demand, such as Atriplex, Haloxylon, Zygophyllum, and Cyperus. While, in the region with a high salt concentration of irrigation water, Salvadora with a strong salt water resistance is afforested. Water used for afforestation projects is all supplied from wells. Irrigation water is supplied by the drip systems. Furthermore, are introduced the afforestation test using Prosopis without irrigation, irrigation system utilizing municipal wastewater, and reforestation of mangrove in Umm Al-Qaiwain. 9 refs., 1 fig., 3 tabs.

    2013-09-01

    Full Text Available Al-Mawardi is a medieval Islamic philosopher. He has expressed that the basic factor ensuring economic life to be held in a healthy environment is justice and the environment of safety occurring because of it. He added, the state must collect its taxes in accordance with the financial situations of the tax payers and in a manner that it would not negatively affect their life standards. He said, the state should spend its income on productive and employment generating fields and on social security services. He defended that, within the free market mechanism, economic life should be operated in accordance with the supply and demand principles and that the state should under no circumstances intervene to the prices. He stated that the state should overtake the role of a regulator and an inspector in issues such as employer-employee conflicts and protecting the rights of woman and child workers. On the basic level, there are some similarities between Al-Mawardi’s views on economy and the views put forward by Classical Liberal School, Keynesian Economics Thought and Monetarist School of Economics, which all emerged in the later years.

    Full Text Available In the wake of September 11, 2001, much has been written about religious groups commonly called ‘terrorist’, building on an older literature whose equally tendentious buzzwords were ‘cult’ and ‘fundamentalism’. In general, the conclusions advanced within such works tilt sometimes in the direction of alarm, and sometimes in that of reassurance. The amount of academic attention devoted to a given threat ought reflect its seriousness, based on calculations of the likelihood that threat will be realized and the destruction it can unleash. Among the most dangerous of situations is that in which an extremely powerful state bent on conquest finds and deploys religious arguments that encourage its aggressive tendencies and imperial ambitions. Believing that it may be useful to consider data sufficiently removed from the present to afford some critical distance, I have devoted much of my research in recent years to the role played by religion in Achaemenid Persia (550–330 bce, the largest, wealthiest, most powerful empire of antiquity before the emergence of Rome. As a convenient summary of that research, I propose to discuss two Achaemenian data, each of which can assume emblematic status. Only after that exercise will I return to contemporary materials and issues.

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

Feed consumption, body weight gain, feed conversion and carcass percentage were recorded to measure the performances. The results of Duncan’s revealed that feed consumption, feed conversion and carcass percentage were not significantly different with increasing level of SHW as substituted crude protein FM in broiler diets. However these parameters in bird fed 100 % SHW diets did not differ from those in birds fed 16 % FM (7.32% crude protein from FM. While body weight gain decreased with increasing levels of SHW in broiler diets (R4. The decrease body weight gain may be due to the decreased feed intake and amino acid in balance and the increased chitin content in the diet. The conclusion of this experiment that SHW can be used as a protein source in broiler diets up to 75% to replace FM.

These nanoparticles have potential applications in clinical medicine and bioimaging, and thus their possible adverse events require thorough investigation. The primary aim of this work was to explore whether the nanoparticles are biocompatible with pneumatocyte bioenergetics (cellular respiration and adenosine triphosphate content. Other objectives included assessments of caspase activity, lung structure, and cellular organelles. Pneumatocyte bioenergetics of murine lung remained preserved after treatment with C–SiO2-etched or C–SiO2 nanoparticles. C–SiO2-etched nanoparticles, however, increased caspase activity and altered lung structure more than C–SiO2 did. Consistent with the known mitochondrial toxicity of cobalt, both C–Co–SiO2 and C–Co3O4–SiO2 impaired lung tissue bioenergetics.

    Full Text Available Background: Cervical cancer is the fourth most common cancer amongst females in the United Arab Emirates (UAE with an estimated incidence of 7.4 per 100,000 persons per year. In March 2008, the Health Authority of Abu Dhabi launched a free school-based campaign to provide all female Emirati students aged 15-17 years in the emirate of Abu Dhabi with the Human Papillomavirus vaccine (HPVV. Despite the proven efficacy of the HPVV in clinical trials, there has been limited research exploring the acceptance of this vaccine within a conservative Islamic society. The media plays a key role in changing beliefs and attitudes towards specific public health initiatives, such as vaccination programmes. The primary aim of this study was to explore the content and communication style of the UAE newspapers (both Arabic and English before, during and after the HPV vaccination programme.Methods: A systematic literature search was conducted on six national newspapers with the highest circulation figures in the UAE (Arabic: Al Ittihad, Al Khaleej, Emarat El Youm; English: Khaleej Times, The National, Gulf News to retrieve articles related to cervical cancer prevention from January 2000 to May 2013.

    Digital soil maps are essential part of the soil assessment framework which supports soil-related decisions and policy-making and therefore it is of crucial importance that they are of known quality. Digital soil mapping is perhaps the next great advancement in soil survey information. Traditional soil survey has always struggled with the collection of data. The amount of soil data and information required to justify the mapping product, how to interpolate date to similar areas, and how to incorporate older data are all challenges that need further exploration. The present study used digital soil mapping to develop a generalized national soil map of the United Arab Emirates with available recent traditional soil survey of Abu Dhabi Emirate (2006-2009) and Northern Emirates (2010-2012), together with limited data from Dubai Emirate, an important part of the country. The map was developed by joining, generalizing, and correlating the information contained in the Soil Survey of Abu Dhabi Emirate, the Soil map of Dubai with limited data, and the Soil Survey of the Northern Emirates. Because the soil surveys were completed at different times and with different standards and procedures, the original map lines and soil classifications had to be modified in order to integrate the three original maps and legends into this single national level map. The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) Global Digital Elevation Model (GDEM) version 2 was used to guide line placement of the map units. It was especially helpful for the Torripsamments units which are separated based on local landscape relief characteristics. A generalized soil map of the United Arab Emirates is produced, which consists of fifteen map units, twelve are named for the soil great group that dominants each unit. Three are named "Rock outcrop", "Mountains", or "Miscellaneous units". Statistical details are also presented. Soil great groups are appropriate taxa to use for soil

    As part of a comprehensive environmental health strategic planning project initiated by the government of Abu Dhabi, we assessed potential dietary exposure in the United Arab Emirates (UAE) to methylmercury (in seafood) and pesticides (in fruits and vegetables) above international guideline levels. We present results for the UAE population by age, gender, and body mass index. Our results show very low daily risks of exposure to pesticides in fruits and vegetables at levels exceeding WHO guidelines even under the conservative assumption that no pesticides are removed during washing and food preparation. Thus, exposure to pesticides on fruits and vegetables does not appear to be a major public health concern in the UAE. The chances of exposure to methylmercury in seafood are much higher; our model estimates a mean 1 in 5 daily risk of exceeding the FAO/WHO provisional tolerable weekly intake. However, great caution should be used in interpreting these results, as we analyzed only the risks and not the substantial benefits of fish consumption. In fact, previous studies have demonstrated that exposure to the n-3 polyunsaturated fatty acids in fish can increase IQ in developing children, and it can substantially decrease the risk in adults of coronary heart disease and stroke. Further research is warranted to compare the risk of Me-Hg exposure from fish to the nutritional benefits of fish consumption in the UAE and to determine appropriate methods to communicate risk and benefit information to the UAE population.

    The MENA Renewables Status Report is an outcome of ADIREC, the Abu Dhabi International Renewable Energy Conference. The report provides a status overview of renewable energy markets, industry, policy and investment trends in the region, drawing on the most recent data available. It is produced in cooperation with over 50 contributors and researchers in the region and reveals massive growth in the renewable energy markets of the Middle East and North Africa (MENA). Regional investment topped US$2.9 billion in 2012, up 40% from 2011 and 650% from 2004. With over 100 projects under development, the region could see a 450% increase in non-hydro renewable energy generating capacity in the next few years. For the report, the 21 MENA countries were clustered into two sub-groups: Net Oil-Exporting Countries (NOEC) -- Algeria, Bahrain, Egypt, Iran, Iraq, Kuwait, Libya, Oman, Qatar, Saudi Arabia, Syria, United Arab Emirates, and Yemen; and Net Oil-Importing Countries (NOIC) -- Djibouti, Israel, Jordan, Lebanon, Malta, Morocco, Palestine, and Tunisia.

  15. Workforce Planning: Case Study of the United Arab Emirates - Human Resources Development

    International Nuclear Information System (INIS)

    Faced with tremendous increases in the long term projected demand for electricity in the United Arab Emirates (UAE), the Government of Abu Dhabi conducted a comprehensive evaluation of its energy needs and potential solutions beginning in 2006. The evaluation was wide-ranging and resulted in the following findings: - The volumes of natural gas that could be made available to the nation's electricity sector would be insufficient to meet future demand. - The burning of liquids (crude oil and/or diesel) would be logistically viable but both costly and environmentally harmful. - Coal fired power generation, while potentially cheaper, would be environmentally unacceptable, and potentially vulnerable from a security of supply standpoint. - The deployment of renewable and other alternative energy supplies, while desirable and an important part of the nation's future energy portfolio, would only be able to supply approximately 6-7% of the required electricity generation capacity by 2020. Peaceful civil nuclear energy emerged as the most effective solution to the demand needs. Four factors supported the decision to begin the UAE programme: - Economics: Well run nuclear energy plants are among the most efficient producers of electricity. - Security of fuel supply: NPPs have high availability factors (in excess of 90%) and can operate for 18-24 months on a single fuel load. - Environment: Nuclear plants emit no greenhouse gases and represent an important tool for combating climate change. - Industrial development: A sustainable nuclear energy programme will create new service industries and high value jobs, while enhancing economic development throughout the UAE

    The purpose of the Human Resources Development Strategy is to identify needed capabilities, assess the ability of the current market to provide those capabilities and then develop skills and abilities in the UAE so that they are available when needed and certainly for the start of operations in the spring of 2017. The goal of the strategy is to provide enough well-qualified people to meet the staffing needs of ENEC, the Prime Contractor, FANR, and UAE industry. These strategies require engaging with key players in Abu Dhabi early in the process so that they contribute to development and implementation of the strategies and become 'owners' who play a part to achieve the ENEC vision and the goal of building a talent pool to support the newborn nuclear industry. Educational programs are designed to support ENEC's long range staffing plan and support national capacity building goals. Strong partnerships are in place with UAE Education Institutions and future collaborations are underway. The potential risks to the success of this strategy include the ability to attract sufficient numbers of people to the program. We believe that these risks can be overcome by implementing intelligent initiatives and leveraging UAE resources

    At the second Clean Energy Ministerial in Abu Dhabi, April 2011 (CEM 2), the Carbon Capture, Use and Storage Action Group (CCUS AG) presented seven substantive recommendations to Energy Ministers on concrete, near-term actions to accelerate global carbon capture and storage (CCS) deployment. Twelve CCUS AG governments agreed to advance progress against the 2011 recommendations by the third Clean Energy Ministerial (London, 25-26 April 2012) (CEM 3). Following CEM 2, the CCUS AG requested the IEA and the Global CCS Institute to report on progress made against the 2011 recommendations at CEM 3. Tracking Progress in Carbon Capture and Storage: International Energy Agency/Global CCS Institute report to the third Clean Energy Ministerial responds to that request. The report considers a number of key questions. Taken as a whole, what advancements have committed CCUS AG governments made against the 2011 recommendations since CEM 2? How can Energy Ministers continue to drive progress to enable CCS to fully contribute to climate change mitigation? While urgent further action is required in all areas, are there particular areas that are currently receiving less policy attention than others, where efforts could be redoubled? The report concludes that, despite developments in some areas, significant further work is required. CCS financing and industrial applications continue to represent a particularly serious challenge.

    The movement and migration pattern of the 'Near Threatened' Sooty Falcon Falco concolor is poorly known. Sooty Falcons breed on the islands of the Arabian Gulf after arriving from their non-breeding areas that are mainly in Madagascar. In the first satellite tracking of the species we fitted a 9.5 g Argos solar powered transmitter on an adult breeding Sooty Falcon off the western coast of Abu Dhabi in the United Arab Emirates. The bird successfully undertook autumn migration to Madagascar, a known wintering area for the species. We document the Sooty Falcon's autumn migration route and stop-over sites. The adult Sooty Falcon initiated its migration at night and with tailwinds, and travelled mainly during daytime hours for 13 days over an inland route of more than 5,656 km. The three stop-over sites in East Africa were characterised by moderate to sparse shrub cover associated with potential sources of water. We discuss the migration pattern of the tracked bird in relation to importance of non-breeding areas for Sooty Falcons and recent declines in numbers in their breeding range.

    Coral reefs of the Arabian Gulf are subject to several pressures, thus requiring conservation actions. Well-designed conservation plans involve efficient mapping and monitoring systems. Satellite remote sensing is a cost-effective tool for seafloor mapping at large scales. Multispectral remote sensing of coastal habitats, like those of the Arabian Gulf, presents a special challenge due to their complexity and heterogeneity. The present study evaluates the potential of multispectral sensor DubaiSat-2 in mapping benthic communities of United Arab Emirates. We propose to use a spectral-spatial method that includes multilevel segmentation, nonlinear feature analysis and ensemble learning methods. Support Vector Machine (SVM) is used for comparison of classification performances. Comparative data were derived from the habitat maps published by the Environment Agency-Abu Dhabi. The spectral-spatial method produced 96.41% mapping accuracy. SVM classification is assessed to be 94.17% accurate. The adaptation of these methods can help achieving well-designed coastal management plans in the region.

    We report on the design of Jeopardy™-like computer game for enhancement of learning of general chemistry for engineering majors. While we examine several parameters of student achievement and attitude, our primary concern is addressing the motivation of students, which tends to be low in a traditionally run chemistry lectures. The effect of the game-playing is tested by comparing paper-based game quiz, which constitutes a control group, and computer-based game quiz, constituting a treatment group. Computer-based game quizzes are Java™-based applications that students run once a week in the second part of the last lecture of the week. Overall effectiveness of the semester-long program is measured through pretest-postest conceptual testing of general chemistry. The objective of this research is to determine to what extent this ``gamification'' of the course delivery and course evaluation processes may be beneficial to the undergraduates' learning of science in general, and chemistry in particular. We present data addressing gender-specific difference in performance, as well as background (pre-college) level of general science and chemistry preparation. We outline the plan how to extend such approach to general physics courses and to modern science driven electives, and we offer live, in-lectures examples of our computer gaming experience.

    Solar Salt (60 wt. % sodium nitrate, 40 wt. % potassium nitrate) is one candidate salt mixture for the CSPonD Demo project (Concentrated Solar Power On Demand Demonstration), ongoing collaboration between Masdar Institute and MIT. One prototype is under preparation at the Masdar Institute Solar Platform in Abu Dhabi. In this new concept, the salt will be used as an open direct absorption solar receiver integrated with a storage system so that the effects of dust/sand and moisture on the thermophysical properties have to be investigated. Thermal Gravimetric Analysis (TGA) was used to study the thermal stability and mass loss, while a Differential Scanning Calorimeter (DSC) was used to study the thermal properties and heat capacity of the salt mixture with and without sand. Considering the worst case scenario, the maximum mass loss rate at 550 °C, and in a fully open configuration, was measured to be 0.29 % per hour, around 2.34 per day of use (8 h of operation). The effect of sand was the same under nitrogen gas environment and air with moisture, which resulted in decreasing the melting temperature of the salts mixture and increasing its freezing temperature. The thermal properties remained stable even after 3 temperature cycles with impurities. Finally, the salt heat capacity increased due to the addition of 2 wt. % of sand.

Applying the theoretical frameworks of Knowledge City and Science Indicators research, we empirically and theoretically studied the emerging Gulf cities Kuwait City (Kuwait, Manama (Bahrain, Doha (Qatar, Abu Dhabi, Dubai, Sharjah (all UAE, and Muscat (Oman. Our methodological framework includes grounded theory, ethnographic field study, ServQual-like quantitative questionnaires and semi-standardized qualitative interviews conducted on-site with informed people, informetrics, and, finally, the use of official statistics. In particular, we describe and analyze the cities' knowledge infrastructures, their academics, and expenditure on R&D as input indicators; and publications as well as graduates as output indicators. A further crucial aspect of a knowledge society is the transition of graduates into knowledge-intensive public services and private companies.

  4. Gas projects surge in the Middle East as governments seek new revenue sources

    International Nuclear Information System (INIS)

    The rapid development of natural gas and condensate reserves in the Middle East results from a simple motivation: the desire of governments to earn revenues. For the past decade, Middle East governments have run budget deficits, which they funded by drawing down foreign assets and issuing debt. Now in the process of structural economic reform, they have begun to use an under-utilized resource--natural gas, of which Middle East governments own about one third of the world's reserves. Governments receive revenues from several sources in natural gas developments, which makes the projects very attractive. Revenue comes from the sale of the natural gas in the domestic market and, if exported, the international market; the sale of associated condensates; the additional exports of crude oil or refined products if natural gas is substituted for refined products in domestic markets; the increased sale of crude oil if natural gas is injected into reservoirs to maintain pressure; and the sale of petrochemicals where natural gas is used as feedstock. Large projects under way in the Middle East highlight the consequences of multiple revenue sources and interlinked costs of natural gas and condensate development. Other countries in the region are undertaking similar projects, so examples cited represent only a portion of what is occurring. The paper describes Abu Dhabi, Qatar, Saudi Arabia, and Iran

    Closing water balance is very crucial on laying effective Water Resources Management strategies. The goal of this study is to assess the potential of satellite imagery to close the water budget over the region of Al Ain city in the Emirate of Abu Dhabi, in the UAE. Water storage variation over the study area was determined from 2005 to 2014 by calculating the difference between inflows and outflows of the system. The outflow included evapotranspiration and discharged wastewater after treatment. The study area comprises Zakher Lake where the treated wastewater is discharged. A series of Landsat images were used to monitor the changes in the lake extent and infer total water volume using a high resolution (15m) digital elevation model. Evapotranspiration was estimated from NCEP reanalysis data over agriculture and green areas in the watershed delineated using Landsat images. The inflow included precipitation, desalinated water supply, and water reuse. Precipitation was obtained from Al Ain airport observations. Water supply from desalination plants and water reuse reported by local authorities were also used. Time series of GRACE observation over the study area were used to assess the inferred water storage variation. The inferred water storage and GRACE anomalies were in agreement as the obtained correlation coefficient was 0.53. Both time series showed a significant decreasing trend suggesting that water storage in the study area is being depleted.

Out of 18 falcons integrated in this study, 16 tested positive to Mycobacterium. avium complex. The 2 negative falcons tested positive in the Mycobacterium genus PCR. Moreover, 1 falcon tested positive to M. avium. paratuberculosis in tissue samples by PCR. In all cases, blood and fecal samples tested negative. In the acid-fast stain, all samples showed the for mycobacteriosis typical rods. Moreover, in 13 samples Acinetobacter baumannii was detected by PCR and proven by DNA sequencing. Clinical features included highly elevated WBCs, heterophilia, lymphocytopenia, monocytosis, severe anemia and weight loss. A. baumannii, a gram-negative bacillus with the ability to integrate foreign DNA, has emerged as one of the major multidrug resistant bacteria. In veterinary medicine, it has so far been detected in dogs, cats, horses and wild birds. To the authors' knowledge, this is the first report of an A. baumannii infection in falcons and of a veterinary Mycobacterium-Acinetobacter coinfection.

    We present a cosmic ray telescope based on the use of plastic scintillator bars coupled to ASD-RGB1S-M Advansid Silicon Photomultipliers (SiPM) through wavelength shifter fibers. The system is comprised of 200 electronic channels organized into 10 couples of orthogonal planes allowing the 3D reconstruction of crossing muons. Two monolithic PCB boards have been designed to bias, readout all the SiPMs enclosed in the system, to monitor the working parameters and to remotely connect the detector. To make easier the display of muon tracks to non-expert users, two LED matrices, triggered by particle interactions, have been implemented. To improve the usability of the muon telescope, a controller board unit permits to select different levels of trigger and allows data acquisition for refined analyses for the more proficient user. A first prototype, funded by INFN and deployed in collaboration with NYUAD, is operating at the Toledo Metro station of Naples, while two further detectors will be developed and installed in Abu Dhabi in the next few months.

    The urban growth of AL Ain city has been investigated using remote sensing data for three different dates, 1972, 1990 and 2000. We used three Landsat images together with socio-economic data in a post-classification analysis to map the spatial dynamics of land use/cover changes and identify the urbanization process in Al Ain resort city, United Arab Emirates. Land use/cover statistics, extracted from Landsat Multi-spectral Scanner (MSS). Thematic Mapper (TM) and Enhanced Thematic Mapper plus (ETM +) images for 1972. 1990 and 2000 respectively, revealed that the built-up area has expanded by about 170.53km2. The city was found to have a tendency for major expansion in four different directions: along the Abu Dhabi highway, along Dubai highway, Myziad direction and Hafeet recreational area. Expansion in any direction was found to be governed by the availability of road network, suitability for construction, utilities, economic activities, geographical constraints, and legal factors (boundary with Sultanate of Oman). The road network in particular has influenced the spatial patterns and structure of urban development, so that the expansion of the built-up areas has assumed an accretive as well as linear growth along the major roads. The research concludes that the development is based on conservation of agricultural areas (oases) and reclamation of the desert for farming and agricultural activities. The integration of remote sensing and GIS was found to be effective in monitoring LULC changes and providing valuable information necessary for planning and research.

  9. Eolian transport of geogenic hexavalent chromium to ground water

    Wood, W.W.; Clark, D.; Imes, J.L.; Councell, T.B.

    2010-01-01

    A conceptual model of eolian transport is proposed to address the widely distributed, high concentrations of hexavalent chromium (Cr+6) observed in ground water in the Emirate of Abu Dhabi, United Arab Emirates. Concentrations (30 to more than 1000 μg/L Cr+6) extend over thousands of square kilometers of ground water systems. It is hypothesized that the Cr is derived from weathering of chromium-rich pyroxenes and olivines present in ophiolite sequence of the adjacent Oman (Hajar) Mountains. Cr+3 in the minerals is oxidized to Cr+6 by reduction of manganese and is subsequently sorbed on iron and manganese oxide coatings of particles. When the surfaces of these particles are abraded in this arid environment, they release fine, micrometer-sized, coated particles that are easily transported over large distances by wind and subsequently deposited on the surface. During ground water recharge events, the readily soluble Cr+6 is mobilized by rain water and transported by advective flow into the underlying aquifer. Chromium analyses of ground water, rain, dust, and surface (soil) deposits are consistent with this model, as are electron probe analyses of clasts derived from the eroding Oman ophiolite sequence. Ground water recharge flux is proposed to exercise some control over Cr+6 concentration in the aquifer.

    In recent years, methicillin-resistant Staphylococcus aureus (MRSA) have become a truly global challenge. In addition to the long-known healthcare-associated clones, novel strains have also emerged outside of the hospital settings, in the community as well as in livestock. The emergence and spread of virulent clones expressing Panton-Valentine leukocidin (PVL) is an additional cause for concern. In order to provide an overview of pandemic, epidemic and sporadic strains, more than 3,000 clinical and veterinary isolates of MRSA mainly from Germany, the United Kingdom, Ireland, France, Malta, Abu Dhabi, Hong Kong, Australia, Trinidad & Tobago as well as some reference strains from the United States have been genotyped by DNA microarray analysis. This technique allowed the assignment of the MRSA isolates to 34 distinct lineages which can be clearly defined based on non-mobile genes. The results were in accordance with data from multilocus sequence typing. More than 100 different strains were distinguished based on affiliation to these lineages, SCCmec type and the presence or absence of PVL. These strains are described here mainly with regard to clinically relevant antimicrobial resistance- and virulence-associated markers, but also in relation to epidemiology and geographic distribution. The findings of the study show a high level of biodiversity among MRSA, especially among strains harbouring SCCmec IV and V elements. The data also indicate a high rate of genetic recombination in MRSA involving SCC elements, bacteriophages or other mobile genetic elements and large-scale chromosomal replacements.

  11. World crude output overcomes Persian Gulf disruption

    International Nuclear Information System (INIS)

    Several OPEC producers made good on their promises to replace 2.7 MMbpd of oil exports that vanished from the world market after Iraq took over Kuwait. Even more incredibly, they accomplished this while a breathtaking 1.2- MMbopd reduction in Soviet output took place during the course of 1991. After Abu Dhabi, Indonesia, Iran, Libya, Nigeria, Saudi Arabia and Venezuela turned the taps wide open, their combined output rose 2.95 MMbopd. Put together with a 282,000-bopd increase by Norway and contributions from smaller producers, this enabled world oil production to remain within 400,000 bopd of its 1990 level. The 60.5-MMbopd average was off by just 0.7%. This paper reports that improvement took place in five of eight regions. Largest increases were in Western Europe and Africa. Greatest reductions occurred in Eastern Europe and the Middle East. Fifteen nations produced 1 MMbopd or more last year, compared with 17 during 1990

    Surficial and buried sediment samples from a hypersaline lagoon-sabkha system (Abu Dhabi, United Arab Emirates) were analysed for carbohydrates (as neutral monosaccharides) to distinguish and characterise various types of recent and ancient tropical ecosystems on a molecular level. The samples consisted of surficial and buried microbial mats, lagoonal sediments containing seagrass ( Halodule uninervis), and mangrove ( Avicennia marina) paleosoils and handpicked mangrove leaves, ranging in age from contemporary to ca. 6000 yr Bp. Analysis of quantitative neutral monosaccharide data by multivariate techniques shows that various groups can be distinguished: intact vascular plant material (mangrove leaf) contains high amounts of arabinose and glucose and hardly any partially methylated monosaccharides, whereas microbial mats in general and lagoonal seagrass sediments show high contributions of fucose, ribose, mannose, galactose and partially methylated monosaccharides. Moreover, surficial microbial mats consisting of filamentous cyanobacteria ( Microcoleus chtonoplastes, Lyngbya aestuarii) can be distinguished from other mats and sediments containing coccoid cyanobacteria ( Entophysalis major) and/or fermenting, sulphate reducing, and methanogenic bacteria on the basis of high contributions of specific groups of partially methylated monosaccharides and other "minor" saccharides. The neutral monosaccharides present in mangrove paleosoils are for a substantial part derived from microorganisms.

    Full Text Available The cultural heritage has always been an important tool in the political and identity formation of the nation-states. In the Western countries the gradual overcoming of nineteenth-century nationalism has paved the way for a post-modern use of their heritage, where tourism, market, culture, leisure and entertainment appear to be deeply interwoven. Museums, monuments and archaeological sites are important elements in the cultural and historical theming of consumption and in the promotion of the areas and requalification of their image. In the last decade the richest states in the Middle East, starting from the United Arab Emirates, have adopted both of these Western uses of heritage: local culture and monuments are used both as means of building or reinventing identity in a religious and national key and as instruments to promote the areas in recreational and tourist function. Dubai and Abu Dhabi are two significant cases. Their intangible heritage, which is enhanced and crystallized in a tourist way, concurs to construct a local historical identity. On the other hand, the major Western national museums, which in Europe have almost exhausted their political and identity function, are called to open branches there to attract international tourism, according to its post-modern model, and to assert the new metropolitan and international identity of these capitals. In such a context of renewed interest in the cultural heritage, we can recall the significant decision of Bahrain of hosting a centre devoted to Arab heritage under the auspices of UNESCO.

    A severe bleaching event affected coral communities off the coast of Abu Dhabi, UAE in August/September, 2012. In Saadiyat and Ras Ghanada reefs ~40% of the corals showed signs of bleaching. In contrast, only 15% of the corals were affected on Delma reef. Bleaching threshold temperatures for these sites were established using remotely sensed sea surface temperature (SST) data recorded by MODIS-Aqua. The calculated threshold temperatures varied between locations (34.48 °C, 34.55 °C, 35.05 °C), resulting in site-specific deviations in the numbers of days during which these thresholds were exceeded. Hence, the less severe bleaching of Delma reef might be explained by the lower relative heat stress experienced by this coral community. However, the dominance of Porites spp. that is associated with the long-term exposure of Delma reef to elevated temperatures, as well as the more pristine setting may have additionally contributed to the higher coral bleaching threshold for this site.

    This research is aimed at exploring the influence of external dynamic louvers on the energy consumption of an office building located in Abu Dhabi-UAE. The IES-VR software was used to predict the energy consumption of a representative office module in order to evaluate the overall energy performance of employing external louvers on the south, east and west oriented facades. The use of dynamic facades was compared to another simpler method of using light-sensor controlled light dimmers. The results show that the potential energy savings using light dimming strategy only was 24.4%, 24.45% and 25.19% for the south, east and west oriented facades, respectively. The proposed dynamic louvers system with light dimming strategy achieved energy savings of 34.02%, 28.57% and 30.31% for the south, east and west orientations, respectively. Detailed analysis of the results showed that the facade's optimal static angle was -20 for the south oriented facade and 20 for the east and west oriented facades. Using these fixed optimal angles resulted in slightly lower energy savings than that of the dynamic facades. This would seem to be a good tradeoff between savings in energy running cost and the investment required to install, operate and maintain a dynamic facades system. (author)

    In April 2006, Dubai Municipality established a broadband seismological network in Dubai Emirate, United Arab Emirates (UAE). This network was the first seismic network in UAE and consists of four remote seismic stations to observe local and regional seismic activity that may have an effect on Dubai Emirate and the surrounding areas. The network exchanges real-time data with the National Center of Meteorology and Seismology in Abu Dhabi, the Earthquake Monitoring Center in Oman and imports in real-time data from few Global Seismic Network stations, which increases the aperture of the network. In April 2012, Dubai Municipality installed an additional five free-field strong motion stations inside the urban area to estimate and publish real-time ShakeMaps for public and decision makers. Although the local seismic activity from April 2006 to June 2013 reflects low seismic activity with the Emirate, it indicates active tectonics in the relatively aseismic northern Oman Mountains region. A few inland clusters of micro-to-small earthquakes have been identified with the new network. A clear cluster of small-to-moderate earthquakes took place in the eastern part of UAE to the east of Masafi, while two clusters of micro-to-small earthquakes took place at Wadi Nazwa and northern Huwaylat. Focal mechanisms of few well recorded earthquakes in this region indicate normal faulting, generally trending NE in parallel to the transition shear zone between the collision at Zagros and the subduction at the Makran zone.

    Digital Rock Physics (DRP) is a novel technology that could be used to generate accurate, fast and cost effective special core analysis (SCAL) properties to support reservoir characterization and simulation tools. For this work, Micro-CT images at different resolutions have been used to run simulations to determine elastic properties like bulk, shear, Young's Modulus and Poisson's ratio of a dry carbonate core plug from Abu Dhabi reservoirs. Pre processing and segmentation of raw images is performed in FEI 3D visualization and analysis tool Avizo. Carbonates are characterized by a very complex pore-space structure and so a high degree of heterogeneity. Abaqus that is based on Finite Element Method is used to run 2D and 3D elastic simulations. Results will be compared by simulating the same core-plug in an alternative segmentation and FEM modeling environment used previously by Jouini & Vega et al. 2012 [1]. Acoustic wave propagation experiments at different confining pressures are performed in the laboratory Triaxial machine to determine the dynamic Young's modulus and Poisson's ratio for the same core plug. Expeirmental results are compared with numerical results. [1] Jouini, M.S. and Vega, S. 2012.

    The present study was conducted to characterize the Technically Enhanced Naturally Occurring Radioactive Materials (TE-NORM) waste generated from oil and gas production. The waste was characterized by means of dry screening solid fractionation, X-ray analysis (XRF and XRD) and {gamma}-ray spectrometry. Sediment of the TE-NORM waste was fractionated into ten fractions with particle sizes varying from less than 100 {mu}m to more than 3 mm. The results showed that the TE-NORM waste contains mainly radionuclides of the {sup 238}U, {sup 235}U and {sup 232}Th series. The mean activity concentrations of {sup 226}Ra (of U-series), {sup 228}Ra (of Th-series) and {sup 40}K in the waste samples before fractionation (i.e. 3 mm) were found to amount to 68.9, 24 and 1.3 Bq/g (dry weight), respectively. After dry fractionation, the activity concentrations were widely distributed and enriched in certain fractions. This represented a 1.48 and 1.82-fold enrichment of {sup 226}Ra and {sup 228}Ra, respectively, in fraction F8 (2.0-2.5 mm) over those in bulk TE-NORM waste samples. The activity ratios of {sup 238}U/{sup 226}Ra, {sup 210}Pb/{sup 226}Ra, {sup 223}Ra/{sup 226}Ra and {sup 228}Ra/{sup 224}Ra were calculated and evaluated. Activity of the most hazardous radionuclide {sup 226}Ra was found to be higher than the exemption levels established by IAEA [International Atomic Energy Agency, 1994. International Basic Safety Standards for the Protection against Ionizing Radiation and for the Safety of Radiation Sources. GOV/2715/94, Vienna]. The radium equivalent activity (Ra-eq), radon ({sup 222}Rn) emanation coefficient (EC) and absorbed dose rate (D {sub {gamma}}{sub r}) were estimated and these are further discussed.

    Full Text Available This study investigates the means of deferring the breakthrough of injected N2 and alleviating the impact of such on production rates and specifications as well as minimizing the required changes to the gas processing facilities. This aimed at assisting the ongoing efforts to transfer the Cantarell experience to Abu Dhabi, where large amounts of N2 gas will be generated and injected into a large gas condensate reservoir to partially substitute the recycling of lean gas. This will bring forward the opportunity to exploit lean gas by securing base load supplies before the start of reservoir blowdown, compared to the peak shaving approach currently practiced. Managing N2 breakthrough starts by better understanding the pattern at which N2 injection spreads into the gas accumulation. Based on the findings of initial subsurface and plant simulations carried out in 2008, N2 breakthrough in Abu Dhabi might be possibly deferred by segmenting the reservoir into a rich N2 region and lean N2 region. The approach assumes no thief zones will be faced and no channeling of N2 injected between the two regions is taking place. N2 is injected in the north region of the reservoir. The production of that region will be segregated and fed to a gas processing plant of lower NGL (natural gas liquid recovery, which essentially takes longer time to start suffering the deterioration of residue gas (gas mixture resulted after separating NGL quality. The residue gas use can be limited to re-injection where the effect of below specification LHV (Low Heat Value would not be an issue. The rest of the reservoir feeds another gas processing plant of higher NGL recovery level from which an amount of residue gas equivalent to that of the injected N2 will be rerouted to the sales network. This scenario will significantly delay as well as downsize the requirement of a N2 rejection plant. There is technical and certainly economical advantage of deferring the

    Urban Sustainability expresses the level of conservation of a city while living a town or consuming its urban resources, but the measurement of urban sustainability depends on what are considered important indicators of conservation besides the permitted levels of consumption in accordance with adopted criteria. This criterion should have common factors that are shared for all the members tested or cities to be evaluated as in this particular case for Abu Dhabi, but also have specific factors that are related to the geographic place, community and culture, that is the measures of urban sustainability specific to a middle east climate, community and culture where GIS Vector and Raster analysis have a role or add a value in urban sustainability measurements or grading are considered herein. Scenarios were tested using various GIS data types to replicate urban history (ten years period), current status and expected future of Abu Dhabi City setting factors to climate, community needs and culture. The useful Vector or Raster GIS data sets that are related to every scenario where selected and analysed in the sense of how and how much it can benefit the urban sustainability ranking in quantity and quality tests, this besides assessing the suitable data nature, type and format, the important topology rules to be considered, the useful attributes to be added, the relationships which should be maintained between data types of a geo- database, and specify its usage in a specific scenario test, then setting weights to each and every data type representing some elements of a phenomenon related to urban suitability factor. The results of assessing the role of GIS analysis provided data collection specifications such as the measures of accuracy reliable to a certain type of GIS functional analysis used in an urban sustainability ranking scenario tests. This paper reflects the prior results of the research that is conducted to test the multidiscipline evaluation of urban

    Devkaran, Subashnie

    2009-01-01

    BACKGROUND: Emergency department (ED) overcrowding is a ubiquitous problem with serious public health implications. The fast track area is a novel method which aims to reduce waiting time, patient dissatisfaction and morbidity. |The study objective was to determine the impact of a fast track area (FTA) on both effectiveness measures (i.e. waiting times [WT] and length of stay [LOS]) and quality measures (i.e. LWBS rates and mortality rates) in non-urgent patients. The secondary objective was to assess if a FTA negatively impacted on urgent patients entering the ED. METHODS: The study took place in a 500 bed, urban, tertiary care hospital in Abu Dhabi, United Arab Emirates. This was a quasi-experimental, which examined the impact of a FTA on a pre-intervention control group (January 2005) (n = 4,779) versus a post-intervention study group (January 2006) (n = 5,706). RESULTS: Mean WTs of Canadian Triage Acuity Scale (CTAS) 4 patients decreased by 22 min (95% CI 21 min to 24 min, P < 0.001). Similarly, mean WTs of CTAS 5 patients decreased by 28 min (95% CI 19 min to 37 min, P < 0.001) post FTA. The mean WTs of urgent patients (CTAS 2\\/3) were also significantly reduced after the FTA was opened (P < 0.001). The LWBS rate was reduced from 4.7% to 0.7% (95% CI 3.37 to 4.64; P < 0.001). Opening a FTA had no significant impact on mortality rates (P = 0.88). CONCLUSION: The FTA improved ED effectiveness (WTs and LOS) and quality measures (LWBS rates) whereas mortality rate remained unchanged.

    Full Text Available Background: The rapid expansion of trials in emerging regions has raised valid concerns about research subject protection, particularly related to informed consent. The purpose of this study is to assess informed consent form (ICF compliance with Good Clinical Practice (GCP guidelines and the readability easeof the ICFs in Abu Dhabi, a potential destination for clinical trials in the UAE. Materials and Methods: A multicenter retrospective cross-sectional analysis of 140 ICFs from industry sponsored and non-sponsored studies was conducted by comparing against a local standard ICF. Flesch-Kincaid Reading Scale was used to assess the readability ease of the forms. Results: Non-sponsored studies had signifi cantly lower overall GCP compliance of 55.8% when compared to 79.5% for industry sponsored studies. Only 33% of sponsored and 16% of non-sponsored studies included basic information on the participants′ rights and responsibilities. Flesch-Kincaid Reading ease score for the informed consent forms from industry sponsored studies was signifi cantly higher 48.9 ± 4.8 as compared to 38.5 ± 8.0 for non-sponsored studies, though both were more complex than recommended. Reading Grade Level score was also higher than expected, but scores for the ICFs from the industry sponsored studies were 9.7 ± 0.7, signifi cantly lower as compared to 12.2 ± 1.3 for non-sponsored studies. Conclusion: In spite of the undisputed benefits of conducting research in emerging markets readability, comprehension issues and the lack of basic essential information call for improvements in the ICFs to protect the rights of future research subjects enrolled in clinical trials in the UAE.

  14. Middle East: the cartel is weakened, but prices are holding. [Extensive survey of all drilling activities in Middle East oil-producing countries

    Energy Technology Data Exchange (ETDEWEB)

    1975-08-15

    The combination of high oil prices and an almost world-wide stagflation resulted in a markedly reduced demand for crude--in the face of ballooning capacity in the Middle East and other OPEC member nations. Under normal economic laws, a surplus supply and declining demand would result in falling prices. But although there was some miniscule price cutting (in the form of longer credit terms, elimination of premiums for low sulfur content, etc.), the cartel maintained its precarious balance in these uncertain economic times. Production curtailments in Saudi Arabia, Kuwait, Iran, Nigeria, Venezuela, and other exporters attested to the decline in demand. However, some of these countries will be strained to produce at a significantly reduced rate for too long a period, with Iran a good case in point. As long as OPEC members can maintain lower production rates, they can efficiently continue to mandate the world price of oil. The one possibility for a reduction is for one or more major producers to unilaterally drop the price. This would, of course, shake OPEC badly. However, Saudi Arabia remains the key simply because of its immense producing capacity and the fact that it can cut its production drastically--to maintain prices--and still accrue sufficient income to support domestic financial needs. Highlights of recent developments in Middle East oil-producing countries are summarized for Saudi Arabia, Iran, Kuwait, Abu Dhabi, Dubai, Sharjar, Fujairah, Ajman, Umm Al Quawain, Ras Al Khaima, Iraq, Qatar, Oman, Syria, Bahrain, Israel, Turkey, Jordan, Lebanon, South Yemen, and Yemen.

    The new concepts of "urban ecology" engaged in searching for solutions involving a balance between energy saving and minimal spending are not new.
    One of their pioneers, the American sociologist Ernest Watson Burgess, established already in the 1930's a scheme of concentric zones as a development of cities based on the experience of Chicago, collected in the book "The City" by Robert E. Park (Chicago, 1935. In the sixties, Le Corbusier designed the master plan for Chandigarh, with the scheme of the city based on a layout of roads known as "The 7 Streets", which ended up being eight after adding the cycle pathways that were so essential to a country such as India. Today, architects such as Norman Foster speak of "Architecture and Sustainability" in their proposals for the new city of Masdar, situated in Abu Dhabi, energy appears as the determining element in the development of the project. Masdar will be the first sustainable city in the world, which will house 50,000 inhabitants and will not emit carbon dioxide into the atmosphere, nor will it generate urban waste.
    This article seeks to place the term eurythmiopolis for the city of the future put forth by Fisac on the current scene, against that of sustainable city proposed by Foster. In his proposal, Fisac includes an idea of ecological city planning where specific functions of the new socialized coexistence, are immersed in an agricultural or forest environment, and exploited using the most advanced scientific and economic techniques.

    Therefore, as Fisac said in his introduction to his book The Urban Molecule: Given the speed at which technology evolves, any urban proposal based on it would condemn the cities of the future not only to aging rapidly, but also to even be born already old : something which could already be occurring to the sustainable city of Masdar.

Davis-Jewish General Hospital, Montreal, QC, Canada Abstract: Carbon nanotubes (CNTs are considered one of the most interesting materials in the 21st century due to their unique physiochemical characteristics and applicability to various industrial products and medical applications. However, in the last few years, questions have been raised regarding the potential toxicity of CNTs to humans and the environment; it is believed that the physiochemical characteristics of these materials are key determinants of CNT interaction with living cells and hence determine their toxicity in humans and other organisms as well as their embryos. Thus, several recent studies, including ours, pointed out that CNTs have cytotoxic effects on human and animal cells, which occur via the alteration of key regulator genes of cell proliferation, apoptosis, survival, cell–cell adhesion, and angiogenesis. Meanwhile, few investigations revealed that CNTs could also be harmful to the normal development of the embryo. In this review, we will discuss the toxic role of single-walled CNTs in the embryo, which was recently explored by several groups including ours. Keywords: single-walled carbon nanotubes, embryo, toxicity

    BACKGROUND: Emergency department (ED) overcrowding is a ubiquitous problem with serious public health implications. The fast track area is a novel method which aims to reduce waiting time, patient dissatisfaction and morbidity. |The study objective was to determine the impact of a fast track area (FTA) on both effectiveness measures (i.e. waiting times [WT] and length of stay [LOS]) and quality measures (i.e. LWBS rates and mortality rates) in non-urgent patients. The secondary objective was to assess if a FTA negatively impacted on urgent patients entering the ED. METHODS: The study took place in a 500 bed, urban, tertiary care hospital in Abu Dhabi, United Arab Emirates. This was a quasi-experimental, which examined the impact of a FTA on a pre-intervention control group (January 2005) (n = 4,779) versus a post-intervention study group (January 2006) (n = 5,706). RESULTS: Mean WTs of Canadian Triage Acuity Scale (CTAS) 4 patients decreased by 22 min (95% CI 21 min to 24 min, P < 0.001). Similarly, mean WTs of CTAS 5 patients decreased by 28 min (95% CI 19 min to 37 min, P < 0.001) post FTA. The mean WTs of urgent patients (CTAS 2\\/3) were also significantly reduced after the FTA was opened (P < 0.001). The LWBS rate was reduced from 4.7% to 0.7% (95% CI 3.37 to 4.64; P < 0.001). Opening a FTA had no significant impact on mortality rates (P = 0.88). CONCLUSION: The FTA improved ED effectiveness (WTs and LOS) and quality measures (LWBS rates) whereas mortality rate remained unchanged.

    Over the past decades, a substantial amount of research has been conducted to model and forecast climatic variables. In this study, Nonparametric Functional Data Analysis (NPFDA) methods are applied to forecast air temperature and wind speed time series in Abu Dhabi, UAE. The dataset consists of hourly measurements recorded for a period of 29 years, 1982-2010. The novelty of the Functional Data Analysis approach is in expressing the data as curves. In the present work, the focus is on daily forecasting and the functional observations (curves) express the daily measurements of the above mentioned variables. We apply a non-linear regression model with a functional non-parametric kernel estimator. The computation of the estimator is performed using an asymmetrical quadratic kernel function for local weighting based on the bandwidth obtained by a cross validation procedure. The proximities between functional objects are calculated by families of semi-metrics based on derivatives and Functional Principal Component Analysis (FPCA). Additionally, functional conditional mode and functional conditional median estimators are applied and the advantages of combining their results are analysed. A different approach employs a SARIMA model selected according to the minimum Akaike (AIC) and Bayessian (BIC) Information Criteria and based on the residuals of the model. The performance of the models is assessed by calculating error indices such as the root mean square error (RMSE), relative RMSE, BIAS and relative BIAS. The results indicate that the NPFDA models provide more accurate forecasts than the SARIMA models. Key words: Nonparametric functional data analysis, SARIMA, time series forecast, air temperature, wind speed

  19. Implementation of the IAEA Code of Conduct on the Safety and Security of Radioactive Sources and its supplementary Import/Export Guidance. National Report from Norway

    International Nuclear Information System (INIS)

    This is the Norwegian Report to the IAEA International Conference on the Safety and Security of Radioactive Sources: Maintaining the Continuous Global Control of Sources throughout their Life Cycle, Abu Dhabi, United Arab Emirates, 27–31 October 2013. This report outlines the Norwegian legislative and regulatory systems of radiation protection. It describes functions and responsibilities of the national regulatory body, to show that the Norwegian radiation protection system is well developed and in accordance with the IAEA Code of Conduct on the Safety and Security of Radioactive Sources. However, the Norwegian authorities will aim to improve the radiation protection policy to further enhance safety and security of radioactive sources, in line with the Code and its supplementary Guidance on the Import and Export of Radioactive Sources. In Norway both services and facilities are available for persons authorized to manage radioactive sources. The national source register is a combined electronic register and notification system for users of radiation sources. Presently the system is being improved to be able to give geographical overviews, to make it possible to search for serial numbers of radiation sources and to make it easier to keep the information in the system updated at any time. These improvements will both contribute to prevent loss of control of radioactive sources and to help in situations with orphan sources. Norway has a well working radioactive waste management system. The general current status is emphasized in this report, but it also contains more specific examples and a short account for the new national administrative practice regarding outphasing of gamma blood irradiators.

  20. Land development assessment on the preserved Al Somalia Island/UAE using multi-temporal aerial photographs and GIS

    International Nuclear Information System (INIS)

    The main objective of this study is to apply the most appropriate change detection techniques to assess land development achievements on Al Sammalyah Island, off the coast of Abu Dhabi, United Arab Emirates capital city. This was accomplished by mapping trajectory of land cover change of the whole island between 1999 and 2005. Another objective was to assess the level of development that occurred on the island and the level of change in the local environment. Available historical large scale aerial photographs from the late nineties to the most recent 2005 were used for the multi temporal study. Geographic information systems (GIS) layers were created by on-screen digitizing of corrected and co-registered images. A GIS overlay analysis combined with post classification change detection method analysis schema was adopted. Results of the current study demonstrate intense land development occurring on the Al Sammalyah Island; vegetation cover extent has increased from 3.742 km/sup 2/ (1.44 miles/sup 2/) in 1999 to 5.101 km/sup 2/ (1.97 miles/sup 2/) in 2005 that corresponds to 36.3% increase over this period. The study also shows that this increase in vegetation extent is mostly attributed to the increase in mangrove planted areas alone with an aerial increase from 2.256 km/sup 2/ (0.87 miles/sup 2/) in 1999 to 3.568 km/sup 2/ (1.38 miles/sup 2/) in 2005, an increase of 58.2% in seven years.

Recently, dietary changes associated with drug therapy have garnered attention as novel drugs to mitigate or ameliorate hypercholesterolemia. The present study was undertaken to observe different dietary polyphenols that can bind to the active site of HMGR and inhibit it. Results from the 12 dietary polyphenols tested reveal that polyphenols can bind to HMGR and block the binding of nicotinamide adenine dinucleotide phosphate (NADP+. We observed that the rigidity of phenolic rings prevents the polyphenols from docking to the enzyme activity site. The presence of an ester linkage between the phenolic rings in (–-epigallocatechin-3-gallate (EGCG and the alkyl chain in curcumin allows them to orient in the active site of the HMGR and bind to the catalytic residues. EGCG and curcumin showed binding to the active site residues with a low GRID score, which may be a potential inhibitor of HMGR. Kaempferol showed binding to HMG-CoA, but with low binding affinity. These observations provide a rationale for the consistent hypolipidemic effect of EGCG and curcumin, which has been previously reported in several epidemiological and animal studies. Therefore, this study substantiates the mechanism of polyphenols on the activity of HMGR by molecular docking and provides the impetus for drug design involving further structure–function relationship studies.

  2. Physiological response of Avicennia marina seedlings to the phytotoxic effects of the water-soluble fraction of Light Arabian crude Oil

    International Nuclear Information System (INIS)

    Stomatal behavior, growth performance and accumulation of polynuclear aromatic hydrocarbons (PAHs) were evaluated in seedlings of the mangrove Avicennia marina (Forssk.) Vierh, treated with the water soluble fraction (WSF) of Abu-Dhabi light Arabian crude oil through foliar spraying or soil application. Irregular stomatal behavior and weak stomatal control over transpiration was observed during the first 24 hours, where stomatal resistance of plants sprayed 150 and 300 (gPAHs plant-1) was significantly lower than that of the control plants. After 6 weeks all treated plants showed no significant difference in their elative growth rate (RGR) or in the net assimilation rate (NAR) compared with the control plants. Tri-aromatic hydrocarbons were the most accumulated in tissues of the treated plants. Penta- and hexa-aromatics, on the other hand, were undetectable in the WSF and consequently in the treated plants. A linear relationship was observed between the dose applied to the plants and the amounts of tissue accumulated PAHs (r=0.515 for soil application and r=0.984 for foliar spray). In plants sprayed with 300 (gPAHs plant-1, the total PAHs accumulated were more than that accumulated in plants with treated through soil application. These findings suggest that :( 1) Aqueous extraction of crude oil tends to signify the percentage of the low molecular weight PAHs, e.g. naphthalene to the total PAHs. (2) Disturbed stomach behavior in the first day of the treatment may be due to the venting of the volatile low molecular weight aromatic hydrocarbons (e.g. benzene, toluene and xylenes) through the stomata. (3) Uptake of water-soluble hydrocarbons by plants is equally possible through both the root system and the foliage. The ecological implications of these findings are discussed in relation to oil pollution of mangrove stands under field conditions. (author)

  3. Distinguishing seawater from geologic brine in saline coastal groundwater using radium-226; an example from the Sabkha of the UAE

    Sabkhat (Salt flats) are common geographic features of low-lying marine coastal areas that develop under hyper-arid climatic conditions. They are characterized by the presence of highly concentrated saline solutions and evaporitic minerals, and have been cited in the geologic literature as present-day representations of hyper-arid regional paleohydrogeology, paleoclimatology, coastal processes, and sedimentation in the geologic record. It is therefore important that a correct understanding of the origin and development of these features be achieved. Knowledge of the source of solutes is an important first step in understanding these features. Historically, two theories have been advanced as to the main source of solutes in sabkha brines: an early concept entailing seawater as the obvious source, and a more recent and dynamic theory involving ascending geologic brine forced upward into the base of the sabkha by a regional hydraulic gradient in the underlying formations. Ra-226 could uniquely distinguish between these sources under certain circumstances, as it is typically present at elevated activity of hundreds to thousands of Bq/m3 (Becquerels per cubic meter) in subsurface formation brines; at exceedingly low activities in open ocean and coastal water; and not significantly supplied to water from recently formed marine sedimentary framework material. The coastal marine sabkha of the Emirate of Abu Dhabi was used to test this hypothesis. The distribution of Ra-226 in 70 samples of sabkha brine (mean: 700 Bq/m3), 7 samples of underlying deeper formation brine (mean: 3416 Bq/m3), the estimated value of seawater (< 16 Bq/m3) and an estimate of supply from sabkha sedimentary framework grains (<~6 Bq/m3) provide the first direct evidence that ascending geologic brine contributes significantly to the solutes of this sabkha system.

    Full Text Available Troposphere ozone layer acts as a shield against all ultraviolet radiation approaching the planet Earth through absorption. It was noticed in mid 80s that ozone layer has thinned on the poles of the planet due to release of man-made substances commonly known as Ozone Depleting Substances, (ODS into its atmosphere. The consequences of this change are adverse as the harmful radiations reach to the surface of the earth, strongly influencing the crops yield and vegetation. These radiations are major cause of skin cancer that has long exposure to Ultra Violet (UV radiation. United States environmental protection agency and European community have imposed strict regulations to curb the emission of ODS and phase out schedules for the manufacture and use of ODS that was specified by Montreal protocol in 1987. Problem statement: This research deled with data analysis of ozone layer thickness obtained from Abu-Dhabi station and detailed measurement of air pollution levels in Kuwait. Approach: The ozone layer thickness in stratosphere had been correlated with the measured pollution levels in the State of Kuwait. The influence of import of ozone depletion substances for the last decade had been evaluated. Other factor that strongly affects the ozone layer thickness in stratosphere is local pollution levels of primary pollutants such as total hydrocarbon compounds and nitrogen oxides. Results: The dependency of ozone layer thickness on ambient pollutant levels presented in detail reflecting negative relation of both non-methane hydrocarbon and nitrogen oxide concentrations in ambient air. Conclusion: Ozone layer thickness in stratosphere had been measured for five years (1999-2004 reflecting minimum thickness in the month of December and maximum in the month of June. The ozone thickness related to the ground level concentration of non-methane hydrocarbon and can be used as an indicator of the health of ozone layer thickness in the stratosphere.

    Full Text Available Routine measurements of the beam irradiance at normal incidence (DNI include the irradiance originating from within the extent of the solar disc only (DNIS whose angular extent is 0.266° ± 1.7 %, and that from a larger circumsolar region, called the circumsolar normal irradiance (CSNI. This study investigates if the spectral aerosol optical properties of the AERONET stations are sufficient for an accurate modelling of the monochromatic DNIS and CSNI under cloud-free conditions in a desert environment. The data from an AERONET station in Abu Dhabi, United Arab Emirates, and a collocated Sun and Aureole Measurement (SAM instrument which offers reference measurements of the monochromatic profile of solar radiance, were exploited. Using the AERONET data both the radiative transfer models libRadtran and SMARTS offer an accurate estimate of the monochromatic DNIS, with a relative root mean square error (RMSE of 5 %, a relative bias of +1 % and acoefficient of determination greater than 0.97. After testing two configurations in SMARTS and three in libRadtran for modelling the monochromatic CSNI, libRadtran exhibits the most accurate results when the AERONET aerosol phase function is presented as a Two Term Henyey–Greenstein phase function. In this case libRadtran exhibited a relative RMSE and a bias of respectively 22 and −19 % and a coefficient of determination of 0.89. The results are promising and pave the way towards reporting the contribution of the broadband circumsolar irradiance to standard DNI measurements.

    Full Text Available INTRODUCTION: Accurate information about the prevalence and types of tobacco use is essential to deliver effective public health policy. We aimed to study the prevalence and modes of tobacco consumption in the United Arab Emirates (UAE, particularly focusing on the use of Midwakh (Arabic traditional pipe. METHODS: We studied 170,430 UAE nationals aged ≥ 18 years (44% males and 56% females in the Weqaya population-based screening program in Abu Dhabi residents during the period April 2008-June 2010. Self-reported smoking status, type, quantity and duration of tobacco smoked were recorded. Descriptive statistics were used to describe the study findings; prevalence rates used the screened sample as the denominator. RESULT: The prevalence of smoking overall was 24.3% in males and 0.8% in females and highest in males aged 20-39. Mean age (SD of smokers was 32.8 (11.1 years, 32.7 (11.1 in males and 35.7 (12.1 in females. Cigarette smoking was the commonest form of tobacco use (77.4% of smokers, followed by Midwakh (15.0%, shisha (waterpipe (6.8%, and cigar (0.66%. The mean durations of smoking for cigarettes, Midwakh, shisha and cigars were 11.4, 9.3, 7.6 and 11.0 years, respectively. CONCLUSIONS: Smoking is most common among younger UAE national men. The use of Midwakh and the relatively young age of onset of Midwakh smokers is of particular concern as is the possibility of the habit spreading to other countries. Comprehensive tobacco control laws targeting the young and the use of Midwakh are needed.

  7. Human Resource Development for Introducing and Expanding Nuclear Power Programmes. Summary of an International Conference

    International Nuclear Information System (INIS)

    Currently, the world is witnessing a resurgence of interest in nuclear power. More than fifty Member States, with support from the IAEA, are considering the introduction of nuclear power, and human resource development is one of the crucial areas in terms of requests for support. The need for human resources in the nuclear sector is not only experienced by countries embarking on new nuclear power programmes, but also by countries with existing programmes that are considering expansion, as many current professionals are approaching retirement age and the number of newly trained staff is generally not sufficient to meet the potential demand. The IAEA conference on Human Resource Development for Introducing and Expanding Nuclear Power Programmes was held from 14 to 18 March 2010 in Abu Dhabi, hosted by the Government of the United Arab Emirates. This conference was organized to address work force issues faced by countries which are embarking on new nuclear power programmes, expanding current programmes or planning to supply nuclear technology to other countries. The situation is different for each country; some need to develop their own local expertise, while others need to scale up existing educational and training programmes to increase the number of professionals. The purpose of this conference was to bring together Member States to help formulate country specific policies on human resource development, education, training and knowledge management to help support each country's nuclear power programme. In addition, the IAEA can facilitate better use of other educational opportunities, including research reactors and development of training facilities. These proceedings highlight the key findings and recommendations of the meeting and the conclusions of the chairperson.

Using the AERONET data both the radiative transfer models libRadtran and SMARTS offer an accurate estimate of the monochromatic DNIS, with a relative root mean square error (RMSE) of 6 % and a coefficient of determination greater than 0.96. The observed relative bias obtained with libRadtran is +2 %, while that obtained with SMARTS is -1 %. After testing two configurations in SMARTS and three in libRadtran for modelling the monochromatic CSNI, libRadtran exhibits the most accurate results when the AERONET aerosol phase function is presented as a two-term Henyey-Greenstein phase function. In this case libRadtran exhibited a relative RMSE and a bias of respectively 27 and -24 % and a coefficient of determination of 0.882. Therefore, AERONET data may very well be used to model the monochromatic DNIS and the monochromatic CSNI. The results are promising and pave the way towards reporting the contribution of the broadband circumsolar irradiance to standard measurements of the beam irradiance.

    A new technique has been applied through Pickett’s plot, to develop some of reservoir petrophysical parameters. These parameters include capillary pressure, pore throat aperture radii, height above the free water table and bulk volume of water. This technique depends on the use of log–log plots of effective porosity versus resistivity combined with empirical relationships for calculating the capillary pressure expressed as a function of permeability, porosity and water saturation. Also, this technique gave the values of petrophysical exponents (m, n and a which were used to calculate the accurate value of water saturation in both clean and shaly rocks and then adjust estimation of hydrocarbon saturation. The integration of these petrophysical parameters on a log–log graph of porosity versus resistivity gives the importance for Pickett plot to be used in reservoir interpretation.

    Menaethiops abumusa n. sp. is closely similar to M. bicornis Alcock, 1985, and M. gadaniensis Kazmi & Tirmizi, 1999, regarding the relatively contiguous rostral spines. The new species is easily distinguishable from its two congeners by having distinctly round angles of orbital eaves and distally divergent rostral spines. Whereas in M. bicornis, and M. gadaniensis, the angles of orbital eaves are anteriorly produced and rostral spines are closely attached to each other along their entire length.  Other morphological differences include the carapace spination/granulation, basal antennal segments, and morphology of the male's first gonopod. Menaethiops gadaniensis was described from Gadani, Pakistan and was only known from the type locality, but is here recorded for the first time from the Gulf of Oman.

    Urinary tract infections (UTIs) are among the most common infectious diseases of humans, with Escherichia coli being responsible for >80% of all cases. Asymptomatic bacteriuria (ABU) occurs when bacteria colonize the urinary tract without causing clinical symptoms and can affect both catheterized...... patients (catheter-associated ABU [CA-ABU]) and noncatheterized patients. Here, we compared the virulence properties of a collection of ABU and CA-ABU nosocomial E. coli isolates in terms of antibiotic resistance, phylogenetic grouping, specific UTI-associated virulence genes, hemagglutination...... with that previously described for the prototype ABU E. coli strain, 83972. This is the first global gene expression analysis of E. coli CA-ABU strains. Overall, our data suggest that nosocomial ABU and CA-ABU E. coli isolates possess similar virulence profiles....

The prevalence of coronary heart disease is promoted in turn by a high prevalence of cardiovascular risk factors, particularly smoking, hypertension, dyslipidemia, diabetes, and sedentary lifestyles. Patients in Africa and the Middle East present with myocardial infarction at a younger age, on average, compared with patients elsewhere. The projected future burden of mortality from coronary heart disease in Africa and the Middle East is set to outstrip that observed in other geographical regions. Recent detailed nationally representative epidemiological data are lacking for many countries, and high proportions of transient expatriate workers in countries such as Saudi Arabia and the United Arab Emirates complicate the construction of such datasets. However, the development of national registries in some countries is beginning to reveal the nature of coronary heart disease. Improving lifestyles (reducing calorie intake and increasing physical activity in patients in the region will be essential, although cultural and environmental barriers will render this difficult. Appropriate prescribing of pharmacologic treatments is essential in the prevention and management of cardiovascular disease. In particular, recent controversies relating to the therapeutic profile of beta-blockers may have reduced their use. The

    In July 2009, Major Economies Forum leaders met to prepare for the COP 15 Copenhagen Conference that took place later that year. At this occasion the Major Economies Forum Global Partnership f or low carbon and climate-friendly technology was founded and Technology Action Plans (TAPs) for ten key low-carbon technologies were drafted. At that juncture Denmark, Germany and Spain took on the responsibility for drafting TAPs for Solar and Wind Energy Technologies. The TAPs were then consolidated and presented at COP 15 that would later take place in December in Copenhagen. Since then, countries that led the development of the Action Plans have started their implementation. During a first Clean Energy Ministerial (CEM) in July 2010 in Washington on the invitation of Steven Chu, US Secretary of Energy, several initiatives were launched. Denmark, Germany and Spain took the lead in the implementation of the TAPs for Solar and Wind Technologies and initiated the Multilateral Working Group on Solar and Wind Energy Technologies (MWGSW). Several countries joined the working group in Washington and afterwards. In two international workshops in Bonn (June 2010) and Madrid (November 2010) and in meetings during the first CEM in Washington (July 2010) and the second CEM in Abu Dhabi (April 2011) the Multilateral Working Group made substantial progress in the two initial fields of action: (1) the Development of a Global Solar and Wind Atlas; and (2) the Development of a Long-term Strategy on Joint Capacity Building. Discussion papers on the respective topics were elaborated involving the Working Group's member countries as well as various international institutions. This led to concrete proposals for several pilot activities in both fields of action. After further specifying key elements of the suggested projects in two expert workshops in spring 2011, the Multilateral Working Group convened for a third international workshop in Copenhagen, Denmark, to discuss the project

  4. Sustainable Electricity and Water for Europe, Middle East and North Africa

    Sufficient supply of energy and water are among the key requirements for a sustainable development of nations. Both depend strongly on energy carriers such as oil, gas, coal and uranium which have limited availability and a negative impact on the environment during their use. Within the framework of a series of detailed studies, conventional and renewable energy sources available for electricity production and desalination in Europe, North Africa and the Middle East (EU-MENA) have been analysed. Scenarios have been developed for a sustainable electricity supply based on increased plant and user efficiency, and an accelerated introduction of renewable energy sources. Even if all potential exclusion criteria are applied and only those technologies are considered which will become economically competitive within the next decades, a potential has been identified which exceeds the present electricity demand by orders of magnitude. Solar energy is, in this context, the by far largest resource which will most economically be exploited in centralised solar thermal power plants. In combination with heat storage, these power plants can provide bulk and peak electricity, and can be combined with thermal or reverse osmosis desalination plants. At present, solar thermal power plants with a total capacity exceeding 10 GW are in operation or under construction in Abu Dhabi, Algeria, Egypt, Iran, Israel, Italy, Morocco, Spain and the USA. Ultimately, the increasing electricity demand of EU-MENA can only be secured in conjunction with the required climate and resource protection targets, if all renewable energy sources are exploited where appropriate, and conversion and user efficiency are increased. To utilise the enormous energy resources of the Mediterranean countries, high voltage direct current power lines will have to be built, linking the most abundant and economic resources with the load centres in the North.

    Mangals occur both as natural mangals and as plantations along the Arabian Gulf coastline of the United Arab Emirates (UAE). Over recent years there has been a significant campaign to extend the area of the mangrove forests, a project that has resulted in significant dredging activity in tandem with the planting of mangrove samplings. The philosophy for this operation has been in order to increase coastal protection from erosion and as a bid to somewhat offset the UAE's carbon footprint. This project, along with significant coastal infrastructure development, has, regrettably, reduced the number of mangal settings that may be considered as pristine. With this in mind, we have undertaken an extensive sampling campaign in order to fully characterise the sediments associated within the depositional sub-environments of mangal systems. Satellite imagery and ground-based reconnaissance were employed to identify a natural mangal area to the East of Abu Dhabi Island. Within this area, a transect was established across a naturally-occurring mangal channel system. Along-transect sampling stations were selected in order to reflect the range of environmental conditions, both in terms of energy and in relation to the degree of tidal exposure. At each station an array of environmental parameters were monitored. These included, but were not limited to, temperature, salinity, current velocity and turbidity. The surface sediment at each sample station was regularly sampled and returned to the laboratory where it was subjected to a range of analysis including grain size and modal analysis, identification of biota and measurement of total organic content. The results of this study allow us to develop a mangal sediment facies map that accurately establishes the relationships between sediments, depositional setting and environmental parameters. These results can be employed to inform the interpretation of ancient successions deposited under similar conditions. Further, the findings of

    This manuscript reports three independent accidental cases of vitamin (Vit) B6 toxicosis in gyrfalcons (Falco rusticolus) and peregrine falcons (Falco peregrinus) and a toxicology study that was conducted to characterize the clinical responses of gyrfalcons and gyrfalcon × peregrine falcons to a range of single intramuscular (IM) and oral (PO) doses of Vit B6. Both lethal and nonlethal doses were determined. Twelve female gyrfalcons died following IM injection of 1 ml of a vitamin B preparation. Within 30 min of injection, the birds passed pistachio green-colored urates and progressed to vomiting, anorexia, cessation of normal activity, ptosis, collapse, and death, occurring 24-36 hr post injections. Three individuals vomited frothy, partially digested blood and had clonic spasms and convulsions. Postmortem and histopathology revealed multifocal severe hepatic necrosis, splenic lymphoid tissue depletion and hemorrhages with arterial necrosis, and acute renal tubular necrosis. Following administration of a different, oral, mineral-vitamin supplement, a total of 21 peregrine falcons in two separate European facilities died suddenly. Histology of the liver showed diffuse congestion and multifocal coagulative necrosis with mild infiltration of heterophils. The particular nutritional supplement, used by both breeders, was analyzed and found to contain 5-9.7% Vit B6. Other randomly selected lots of the product contained 0.007-0.27% Vit B6. According to the product label, Vit B6 should have been present at 0.004%. To confirm the hypothesis that Vit B6 was responsible for the deaths of the falcons in Abu Dhabi, Vit B6 (British Pharmacopoeia [BP] grade) in powder form was diluted in water for injection and administered IM to four groups of falcons. Groups of four gyrfalcon × peregrine hybrid falcons or gyrfalcons (or both) were given a single IM dose of 5, 10, 15, or 20 mg/kg of Vit B6 or received an oral dose of 25, 50, or 75 mg of Vit B6.

    businessman in Abu Dhabi since 1965, emigrants will invest in an industry only if they are convinced of the viability of the project, have a say in its management, and if there is reservation of jobs in the enterprise for their competent dependants. Thus far, the money mobilized into industry seems to be only a tiny proportion of the remittances. A major avenue of investment for the emigrants is real estate and, consequently, the prices of land have registered a marked increase. Even the service sector -- taxis and travel agencies -- have received a sizable boost because of the inflow of Gulf money into the state. According to G. Narayana Pillai, culturally and socially the new found wealth will not bring about any substantial social improvement. PMID:12265616

    A possible syngenetic relationship between carbonate and clay mineral precipitation has been reported for sedimentary rocks deposited in both lacustrine and marine sedimentary environments throughout the geological record. In particular, the mineral dolomite is often found associated with Mg-rich clays, such as stevensite. It is notable that this carbonate/clay association has been recorded in numerous samples taken from modern dolomite precipitating environments; for example, the Coorong lakes, South Australia, coastal sabkhas, Abu Dhabi, UAE and coastal hypersaline lagoons (Lagoa Vermelha and Brejo do Espinho) east of Rio de Janeiro, Brazil. An HRTEM study of samples from these three locations indicates a possible physical/chemical association between the Ca-dolomite and Mg-rich clays, demonstrating a probable co-precipitation. To test this hypothesis, we have conducted a series of biotic and abiotic laboratory experiments. If this syngenesis actually occurs in nature, what, if any, are the biogeochemical processes controlling these precipitation reactions? Our experiments were designed to determine the extent of the biotic versus abiotic component influencing the mineral precipitation and, in the case of a biotic influence, to understand the mechanism through which microorganisms might mediate the formation of clay minerals. The experiments were carried out in the Geomicrobiology Laboratory of ETH Zürich using cultures of living microbes and artificial organic compounds that simulate functional groups present in natural biofilms formed under both aerobic and anaerobic conditions. In addition, pure inorganic experiments were designed to understand possible physico-chemical conditions for diagenetic processes that could induce dissolution of Mg-carbonates and precipitation of Mg-rich clays. Our results show a remarkable biotic influence during the formation of clay minerals. Specifically, extracellular polymeric substances (EPS), released by microbes in their

    The work in this thesis demonstrates the assessment of the energy budget inside microbial mat ecosystems, and the factors affecting light utilization efficiency. It presents the first balanced light energy budget for benthic microbial mat ecosystems, and shows how the budget and the spatial distribution of the local photosynthetic efficiencies within the euphotic zone depend on the absorbed irradiance (Jabs). The energy budget was dominated by heat dissipation on the expense of photosynthesis. The maximum efficiency of photosynthesis was at light limiting conditions When comparing three different marine benthic photosynthetic ecosystems (originated from Abu-Dhabi, Arctic, and Exmouth Gulf in Western Australia), differences in the efficiencies were calculated. The results demonstrated that the maximum efficiency depended on mat characteristics affecting light absorption and scattering; such as, photopigments ratio and distribution, and the structural organization of the photosynthetic organisms relative to other absorbing components of the ecosystem (i.e., EPS, mineral particles, detritus, etc.). The maximum efficiency decreased with increasing light penetration depth, and increased with increasing the accessory pigments (phycocyanin and fucoxanthin)/chlorophyll ratio. Spatial heterogeneity in photosynthetic efficiency, pigment distribution, as well as light acclimation in microbial mats originating from different geographical locations was investigated. We used a combined pigment imaging approach (variable chlorophyll fluorescence and hyperspectral imaging), and fingerprinting approach. For each mat, the photosynthetic activity was proportional to the local pigment concentration in the photic zone, but not for the deeper layers and between different mats. In each mat, yield of PSII and E1/2 (light acclimation) generally decreased in parallel with depth, but the gradients in both parameters varied greatly between samples. This mismatch between pigments concentration

However, there are few trials that have determined the effect of antidiabetic treatment in an observational setting in these countries. Methods: This was a noninterventional study performed in Morocco in 2006–2007 and in the Middle East in 2005–2006 to observe the efficacy and safety of acarbose in patients with pretreated or untreated type 2 diabetes. Glycemic parameters (fasting blood glucose, one-hour postprandial blood glucose, and HbA1c were recorded within a 3-month period. The observation period included an initial visit at the start of acarbose therapy and up to three follow-ups. Results: Acarbose was effective in reducing glycemic parameters in patients from Morocco (n = 1082 and the Middle East (n = 1737. The mean one-hour postprandial blood glucose decreased by 35.5% to 165.4 ± 47.9 mg/dL in the Middle East and by 35.5% to 179.0 ± 49.9 mg/dL in Morocco. Mean fasting blood glucose decreased by 30.8% to 126.6 ± 34.2 mg/dL (Middle East and by 34.5% to 150.6 ± 47.1 mg/dL (Morocco. The absolute reduction in HbA1c was 1.3% in the Middle East (final value 7.4% and 1.0% in Morocco (final value 7.5%. Overall, 107 patients (Middle East and 26 patients (Morocco experienced minor drug-related adverse events, which were mainly gastrointestinal. The tolerability of acarbose was rated as very good/good by 80.8% in the Middle East and by 68.6% in Morocco.

    In some patients, Escherichia coli strains establish significant bacteriuria without causing symptoms of urinary tract infection (UTI). These asymptomatic-bacteriuria (ABU) strains have been shown to express fewer virulence factors than the uropathogenic E. coli (UPEC) strains that cause severe, symptomatic UTI. Paradoxically, ABU strains carry many typical UPEC virulence genes, and the molecular basis of their low virulence therefore remains unclear. This study examined whether ABU strains m...

Here the biofilm-forming capacity on abiotic surfaces of selected E coli ABU strains and UPEC strains in human urine...... was investigated. It was found that there is a strong bias for biofilm formation by the ABU strains. Not only were the ABU strains significantly better biofilm formers than UPEC strains, they were also able to out-compete UPEC strains as well as uropathogenic strains of Klebsiella spp. during biofilm formation.......

    Some 300 international experts, decision makers, government officials, regulators and industry representatives are expected for this event, which follows the first major con-ference on human resource development for introducing and expanding nuclear power programmes, held in Abu Dhabi, United Arab Emirates, in 2010. Capacity building is a major first step in the process of ensuring that a qualified work-force is available and ready to assume the responsibility for safe, responsible and sus-tainable use of nuclear technologies. Capacity building needs to be sustained throughout the life of a nuclear power programme. The IAEA Action Plan on Nuclear Safety (2011) underlined the importance of capacity building: one of the actions calls upon both oper-ating and 'newcomer' Member States to strengthen, develop, maintain and implement their capacity building programmes. Also, the critical role of human resources and ca-pacity building in developing and maintaining nuclear infrastructure was reiterated by subsequent international experts' meetings related to this topic. The IAEA is pleased to announce that Mr Pal Kovacs, Minister of State for Energy Affairs at the Ministry of National Development of Hungary has accepted the role of President of the 2014 Conference. Individual session chairs will represent newcomer and operating countries, heads of organizations leading nuclear power programmes, regulatory bodies, technical support organizations and nuclear power plants. Interest has been high in the international community, which is evident from the high number of expected participants as well as from the 137 papers submitted. The conference focuses on the global challenges of capacity building, human resource development, education and training, nuclear knowledge management and establishing and maintaining knowledge networks. In particular, the conference reviews developments in the global status of human resource development since the 2010 international conference

  10. Drilling the Mediterranean Messinian Evaporites to Answer Key Questions Related to Massive Microbial Dolomite Formation under Hypersaline Alkaline Conditions

    dolomite precipitation has been studied extensively in rare modern environments, such as the arid coastal sabkhas of Abu Dhabi, UAE and the hypersaline coastal lagoons in Brazil. However, extrapolation of these studies of relatively limited aerial extent to interpret larger-scale, ancient dolomite formation of putative evaporitic origin remains elusive. Such ancient micritic dolomite formations with associated micro-porosity represent extremely valuable hydrocarbon reservoirs. Therefore, a comprehensive investigation of a relatively recent micritic dolomite deposit that has not experienced extensive burial depths and diagenesis is essential to extend our understanding of these important reservoir systems. Based on the limited data obtained during drilling at DSDP Site 374: Messina Abyssal Plain, the dolomitic mudstones of the uppermost Messinian evaporite complex represent an ideal candidate for such an extensive study in a "natural laboratory". Thus, to increase our understanding of the biogeochemical processes associated with ancient massive dolomite formation, we propose to document the scientific objectives to support a major new drilling campaign to study the sub-seafloor Messinian evaporite complex in the deep Mediterranean basins, using greatly enhanced drilling technology that is currently available within the new International Ocean Discovery Program (IODP).

  11. Sources and potential application of waste heat utilization at a gas processing facility

    Science.gov (United States)

    Alshehhi, Alyas Ali

    Waste heat recovery (WHR) has the potential to significantly improve the efficiency of oil and gas plants, chemical and other processing facilities, and reduce their environmental impact. In this Thesis a comprehensive energy audit at Abu Dhabi Gas Industries Ltd. (GASCO) ASAB gas processing facilities is undertaken to identify sources of waste heat and evaluate their potential for on-site recovery. Two plants are considered, namely ASAB0 and ASAB1. Waste heat evaluation criteria include waste heat grade (i.e., temperature), rate, accessibility (i.e., proximity) to potential on-site waste heat recovery applications, and potential impact of recovery on installation performance and safety. The operating parameters of key waste heat source producing equipment are compiled, as well as characteristics of the waste heat streams. In addition, potential waste heat recovery applications and strategies are proposed, focusing on utilities, i.e., enhancement of process cooling/heating, electrical/mechanical power generation, and steam production. The sources of waste heat identified at ASAB facilities consist of gas turbine and gas generator exhaust gases, flared gases, excess propane cooling capacity, excess process steam, process gas air-cooler heat dissipation, furnace exhaust gases and steam turbine outlet steam. Of the above waste heat sources, exhaust gases from five gas turbines and one gas generator at ASAB0 plant, as well as from four gas turbines at ASAB1 plant, were found to meet the rate (i.e., > 1 MW), grade (i.e., > 180°C), accessibility (i.e., generated at ASAB1, approximately 173 MW are recovered by waste heat recovery steam generators (WHRSGs), leaving 116 MW unutilized. The following strategies were developed to recover the above waste heat. At ASAB0, it is proposed that exhaust gases from all five gas turbines be used to power a WHRSG. The steam generated by the WHRSG would both i) drive an absorption refrigeration unit for gas turbine inlet air cooling

    Seismic hazard assessment for Oman is conducted utilizing probabilistic approach. Probabilistic Seismic Hazard Assessment (PSHA) has been performed within a logic tree framework. An earthquake catalogue for Oman was compiled and declustered to include only independent earthquakes. The declustered catalogue was used to define seismotectonic source model with 26 source zones that characterize earthquakes in the tectonic environments in and around Oman. The recurrence parameters for all the seismogenic zones are determined using the doubly bounded exponential distribution except the seismogenic zones of Makran subduction zone which were modeled using the characteristic distribution. The maximum earthquakes on known faults were determined geologically and the remaining zones were determined statistically from the compiled catalogue. Horizontal ground accelerations in terms of geometric mean were calculated using ground-motion prediction relationships that were developed from seismic data obtained from the shallow active environment, stable craton environment, and from subduction earthquakes. In this analysis, we have used alternative seismotectonic source models, maximum magnitude, and attenuation models and weighted them to account for the epistemic uncertainty. The application of this methodology leads to the definition of 5% damped seismic hazard maps at rock sites for 72, 475, and 2475 year return periods for spectral accelerations at periods of 0.0 (corresponding to peak ground acceleration), 0.1, 0.2, 0.3, 1.0 and 2.0 sec. Mean and 84th percentile acceleration contour maps were represented. The results also were displayed as uniform hazard spectra for rock sites in the cities of Khasab, Diba, Sohar, Muscat, Nizwa, Sur, and Salalah in Oman and the cities of Abu Dhabi and Dubai in UAE. The PGA across Oman ranges from 20 cm/sec2 in the Mid-West and 115 cm/sec2 at the northern part for 475 years return period and between 40 cm/sec2 and 180 cm/sec2 for 2475 years

    The study of large amounts of dolomite that formed in the Triassic Tethyan realm is hampered by late diagenetic or hydrothermal overprint. These dolomites are difficult to link to past environmental and early diagenetic conditions, and their correlation to models for dolomite formation in modern environments is problematic. Preto et al. (2015) suggested, based on evidence from nano-scale structure analysis by transmission electron microscopy and petrographic observations, that dolomites in the Carnian Travenanzes Formation of the Southern Alps (Dolomites area) represent a preserved primary phase. The Travenanzes Formation was deposited in an extended alluvial plain or coastal sabkha environment subject to a semi-arid climate. Beds and nodules of nearly stoichiometric dolomite are embedded in large amounts of clay, which shielded early formed dolomite from diagenetic fluids. This finding of penecontemporaneous dolomite provides an ideal model case for reconstructing past environmental conditions at the time of dolomite precipitation. While Preto et al. (2015) argued that dolomite formation was mediated by extracellular polymeric substances produced by sulphate-reducing bacteria, it remains unclear whether precipitation occurred from evaporating seawater or mainly from brine derived from evaporating continental groundwater. Both cases exist in modern environments of dolomite formation. In the coastal sabkhas of Abu Dhabi and Qatar, dolomite precipitates from concentrated brine derived from seawater, either through seepage and reflux or through evaporative pumping (the sabkha model). In the coastal ephemeral lakes of the Coorong Lagoon system (South Australia) dolomite precipitation occurs from evaporating groundwater. The goal of this study is to distinguish marine from continental influence during formation of Carnian dolomite using 87Sr/86Sr isotope ratios. Sr isotopes could reveal different origins of ionic solutions for dolomite precipitation, which is not

    The Arabian Gulf region is moving towards a nuclear energy option with the first nuclear power plant now operational in Bushehr, Iran, and others soon to be constructed in Abu Dhabi and Saudi Arabia. Radiological safety is becoming a prime concern in the region. This study compiles available data and presents recent radionuclide data for the northern Gulf waters, considered as pre-nuclear which will be a valuable dataset for future monitoring work in this region. Radionuclide monitoring in the marine environment is a matter of prime concern for Kuwait, and an assessment of the potential impact of radionuclides requires the establishment and regular updating of baseline levels of artificial and natural radionuclides in various environmental compartments. Here we present baseline measurements for (210)Po, (210)Pb, (137)Cs, (90)Sr, and (3)H in Kuwait waters. The seawater concentration of (3)H, (210)Po, (210)Pb, (137)Cs, and (90)Sr vary between 130-146, 0.48-0.68, 0.75-0.89, 1.25-1.38 and 0.57-0.78 mBq L(-1), respectively. The (40)K concentration in seawater varies between 8.9-9.3 Bq L(-1). The concentration of (40)K, total (210)Pb, (137)Cs, (90)Sr, (226)Ra, (228)Ra, (238)U, (235)U, (234)U, (239+240)Pu and (238)Pu were determined in sediments and range, respectively, between 353-445, 23.6-44.3, 1.0-3.1, 4.8-5.29, 17.3-20.5, 15-16.4, 28.7-31.4, 1.26-1.30, 29.7-30.0, 0.045-0.21 and 0.028-0.03 Bq kg(-1) dry weight. Since, radionuclides are concentrated in marine biota, a large number of marine biota samples covering several trophic levels, from microalgae to sharks, were analyzed. The whole fish concentration of (40)K, (226)Ra, (224)Ra, (228)Ra, (137)Cs, (210)Po and (90)Sr range between 230-447, 0.7-7.3, <0.5-6.6, <0.5-15.80, <0.17, 0.88-4.26 and 1.86-5.34 Bq kg(-1) dry weight, respectively. (210)Po was found to be highly concentrated in several marine organisms with the highest (210)Po concentration found in Marica marmorata (193.5-215.6 Bq kg(-1) dry weight). (210)Po in

Moreover, Antelope, as typical middleware, allows the scientist and software developer to focus on the specific purpose of their application by providing well defined input/output interfaces. This will spur the development of original and inventive real-time processing schemes in the realm of volcano monitoring. Whatever the underlying data and information engine is, it is only as good as the frontend. Such a frontend has to accommodate the dual purpose of putting data and information in a form that is conducive for scientist and the emergency responder. Current projects in Italy and Abu Dhabi with multiple display centers gave us insights into how difficult it is to develop a multipurpose situation room. Currently, we are experimenting with sophisticated emergency management software that ties strong-motion measurement, structural behavior, and loss estimation to a situation-driven response plan. Although different in content and timeline, this can be adapted for developing volcano eruptions. A final word on remote sensing data, e.g. infrared imaging from an airplane: If the data can be streamed, there is a way to time tag them and include them in the broader real-time process. At least, batch processing should be considered in order to improve the overall information status pre- or post-event.

    major undertaking and I would be grateful for the active support of all Member States. The IAEA Action Plan on Nuclear Safety calls for Member States to make more use of IAEA peer reviews. Many have done so. However, not all Member States with nuclear power have requested operational safety review - OSART - missions in line with the Action Plan. I encourage all countries to do so. This would help to achieve a high level of safety nuclear power plants, including adequate preparedness to manage severe accidents. Of course, nuclear safety is not just about nuclear power plants and fuel cycle facilities. It is also important to protect the public and the environment from exposure to radioactive sources, and to protect medical staff and patients from unnecessary and unintended exposure to radiation. These are issues for all countries. In December, the Agency organized an international conference in Bonn, Germany on Radiation Protection in Medicine. The Conference agreed the Bonn Call for Action, which recommended practical measures to improve protection for patients and health workers against over-exposure to ionizing radiation. In October this year, an International Conference on the Safety and Security of Radioactive Sources will be held in Abu Dhabi, United Arab Emirates. I encourage all Member States to participate. Preparations for the IAEA International Conference on Nuclear Security in July are progressing. I am grateful to the Minister of Foreign Affairs of Hungary, His Excellency Mr. Janos Martonyi, for agreeing to serve as President of this Conference. I encourage all countries to participate at ministerial level. The Ambassador of Hungary will take the lead in coordinating open-ended consultations among Member States. The Ambassador of Brazil, who has been acting as Chairman of the Programme Committee for this Conference, will act as Co-Chair. I thank Ambassadors Csuday and Vinhas for their willingness to take on these important roles.

    draw upon advances in soil and weather sensor and controller technologies. Recent water budget analyses have sought to trace water flows at the global scale, as wel as the water footprints of industrial supply chains, and the water alocation and pricing institutions for urban and site scales. Adaptation of these ideas and methods across a range of scales -- from the human body to the building, site, city, region, and globe -- represents an exciting frontier for arid zone design, and a valuable contribution to the field of water-conserving design more broadly. These prospects are ilustratrated in a series of case studies from the garden complexes of Agra and Nagaur in India to a "new aflaj" system in Abu Dhabi.

  19. Bacterial Suppression of RNA Polymerase II-Dependent Host Gene Expression

    Ines Ambite

    2016-07-01

    Full Text Available Asymptomatic bacteriuria (ABU is a bacterial carrier state in the urinary tract that resembles commensalism at other mucosal sites. ABU strains often lack the virulence factors that characterize uropathogenic Escherichia coli (E. coli strains and therefore elicit weak innate immune responses in the urinary tract. In addition, ABU strains are active modifiers of the host environment, which they influence by suppressing RNA polymerase II (Pol II-dependent host gene expression. In patients inoculated with the ABU strain E. coli 83972, gene expression was markedly reduced after 24 h (>60% of all regulated genes. Specific repressors and activators of Pol II-dependent transcription were modified, and Pol II Serine 2 phosphorylation was significantly inhibited, indicating reduced activity of the polymerase. This active inhibition included disease–associated innate immune response pathways, defined by TLR4, IRF-3 and IRF-7, suggesting that ABU strains persist in human hosts by active suppression of the antibacterial defense. In a search for the mechanism of inhibition, we compared the whole genome sequences of E. coli 83972 and the uropathogenic strain E. coli CFT073. In addition to the known loss of virulence genes, we observed that the ABU strain has acquired several phages and identified the lytic Prophage 3 as a candidate Pol II inhibitor. Intact phage particles were released by ABU during in vitro growth in human urine. To address if Prophage 3 affects Pol II activity, we constructed a Prophage 3 negative deletion mutant in E. coli 83972 and compared the effect on Pol II phosphorylation between the mutant and the E. coli 83972 wild type (WT strains. No difference was detected, suggesting that the Pol II inhibitor is not encoded by the phage. The review summarizes the evidence that the ABU strain E. coli 83972 modifies host gene expression by inhibition of Pol II phosphorylation, and discusses the ability of ABU strains to actively create an

    Egyptian phosphorites from Abu Tartur (Western Desert), El Mahamide mine (Nile Valley) and Rabah mine (Eastern Desert) show variable degrees of relative REE enrichment.Black plateau phosphorites of Abu Tartur are substantially enriched in REE as compared to the Red Sea and Nile Valley phosphorites. P-rich organic matter from the Abu Tartur and Rabah mines recorded negative Ce and positive Eu anomalies. Positive Eu anomaly reveals an anoxic event prior to the phase of Late Cretaceous phosphate formation. Ce is a redox indicator. Mixing of sea water and upwelling during the Late Cretaceous was responsible for the recording of positive Eu and negative Ce anomalies in the Egyptian phosphorites.

    Streptococcus agalactiae can cause urinary tract infection (UTI) including cystitis and asymptomatic bacteriuria (ABU).

    Full Text Available Purpose: Escherichia coli isolated from asymptomatic bacteriuria (ABU correlated genotypically and phenotypically with cystitis isolates may help in distinguishing urovirulence determinants from 'fitness factors', latter necessary only for survival of E. coli in urinary tract; for gaining insight into the pathogenesis of urinary tract infection. Materials and Methods: In this cross-sectional study, we compared genotypic (phylogroups and 15 putative virulence genes, and phenotypic profiles of ABU E. coli strains with our previously genotyped collection of cystitis isolates. Virulence score was calculated for each isolate as a number of virulence genes detected. Results: Significant differences were observed in the proportion of four phylogenetic groups (P = 0.009 amongst cystitis and ABU isolates. Average virulence score was higher for ABU isolates (6.6 than cystitis strains (4.2; and hlyA (P = 0.001, cytotoxic necrotising factor 1 (P = 0.00, fyuA (P = 0.00, ibeA (P = 0.00, kpsMII (P = 0.01, and malX/pathogenicity-associated island (P = 0.01 were more frequently present in ABU strains. Conclusions: The expression of adhesins, haemolysin, aerobactin, and capsule synthesis gene were similar in two groups suggesting their role as fitness factors. ABU isolates were better biofilm producers, reflecting its importance in silent persistence. Serum resistance gene which was more expressed in cystitis isolates may represent virulence determinant. Genetic makeup of E. coli does not change much rather genes helping in survival and colonisation are expressed equally in ABU and cystitis isolates as opposed to phenotypic attenuation of those that helps in invasion or inflammation in ABU isolates.

  10. Flow field simulation and establishment for mathematical models of flow area of spool valve with sloping U-shape notch machined by different methods

    Institute of Scientific and Technical Information of China (English)

    王兆强; 顾临怡; 冀宏; 陈家旺; 李林

    2014-01-01

    Precise function expression of the flow area for the sloping U-shape notch orifice versus the spool stroke was derived. The computational fluid dynamics was used to analyze the flow features of the sloping U-shape notch on the spool, such as mass flow rates, flow coefficients, efflux angles and steady state flow forces under different operating conditions. At last, the reliability of the mathematical model of the flow area for the sloping U-shape notch orifice on the spool was demonstrated by the comparison between the orifice area curve derived and the corresponding experimental data provided by the test. It is presented that the bottom arc of sloping U-shape notch (ABU) should not be omitted when it is required to accurately calculate the orifice area of ABU. Although the theoretical flow area of plain bottom sloping U-shape notch (PBU) is larger than that of ABU at the same opening, the simulated mass flow and experimental flow area of ABU are both larger than these of PBU at the same opening, while the simulated flow force of PBU is larger than that of ABU at the same opening. Therefore, it should be prior to adapt the ABU when designing the spool with proportional character.

  11. Variation in endogenous oxidative stress in Escherichia coli natural isolates during growth in urine

    2012-06-01

    Full Text Available Abstract Background Uropathogenic strains of Escherichia coli cause symptomatic infections whereas asymptomatic bacteriuria (ABU strains are well adapted for growth in the human urinary tract, where they establish long-term bacteriuria. Human urine is a very complex growth medium that could be perceived by certain bacteria as a stressful environment. To investigate a possible imbalance between endogenous oxidative response and antioxidant mechanisms, lipid oxidative damage estimated as thiobarbituric acid reactive substances (TBARS content was evaluated in twenty-one E. coli belonging to various pathovars and phylogenetic groups. Antioxidant defense mechanisms were also analysed. Results During exponential growth in urine, TBARS level differs between strains, without correlation with the ability to grow in urine which was similarly limited for commensal, ABU and uropathogenic strains. In addition, no correlation between TBARS level and the phylogroup or pathogenic group is apparent. The growth of ABU strain 83972 was associated with a high level of TBARS and more active antioxidant defenses that reduce the imbalance. Conclusions Our results indicate that growth capacity in urine is not a property of ABU strains. However, E. coli isolates respond very differently to this stressful environment. In strain ABU 83972, on one hand, the increased level of endogenous reactive oxygen species may be responsible for adaptive mutations. On the other hand, a more active antioxidant defense system could increase the capacity to colonize the bladder.

  12. Remarks at the International Conference on Human Resource Development for Introducing and Expanding Nuclear Power Programs

    International Nuclear Information System (INIS)

    Thank you and good morning, everyone. I am pleased to be in Abu Dhabi, which I have heard so much about but have never visited before. During my tenure at the U.S. Nuclear Regulatory Commission as Chairman and now as a Commissioner, I have traveled extensively across the globe in support of international nuclear safety and security and visited a number of countries. So, I can say with some experience that this is one of the most impressive examples of modern development that I have encountered anywhere in my travels. I congratulate the UAE for its commitment to national development, to this location, and to the ideal of progress toward a bright future. The topic of this conference - human resources development and the expansion of nuclear power - is about the commitment and investment in people. The importance of this 'human side' of modern technology is sometimes forgotten or assumed to develop on its own once basic educational programs and institutions are put in place. In my view, the development and maintenance of a skilled national workforce is critical to the development of a stable, successful national nuclear power program. As many of you know, I am on leave from the University of Texas and will soon be returning there. And because of my academic background, I have made the need to expand scientific and engineering education and to promote technological development a recurring theme in my numerous presentations while serving at the U.S. NRC. So I am pleased to participate in this conference today and to share the podium for this keynote address session with my distinguished and honorable colleague from India, Mr. Rajagopala Chidambaram. I also want to commend the International Atomic Energy Agency for convening this special conference on this vital subject. The subject of highly qualified, nuclear trained people has been a significant theme in my speeches and private conversations. There is little doubt that ensuring there will be enough trained and

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

  6. Radioactivity and distribution of U and Th in some granitic masses, Wadi El-Saqia area, Central Eastern Desert, Egypt

    International Nuclear Information System (INIS)

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

    Full Text Available Abstract Background Lectins are mainly described as simple carbohydrate-binding proteins. Previous studies have tried to identify other binding sites, which possible recognize plant hormones, secondary metabolites, and isolated amino acid residues. We report the crystal structure of a lectin isolated from Canavalia gladiata seeds (CGL, describing a new binding pocket, which may be related to pathogen resistance activity in ConA-like lectins; a site where a non-protein amino-acid, α-aminobutyric acid (Abu, is bound. Results The overall structure of native CGL and complexed with α-methyl-mannoside and Abu have been refined at 2.3 Å and 2.31 Å resolution, respectively. Analysis of the electron density maps of the CGL structure shows clearly the presence of Abu, which was confirmed by mass spectrometry. Conclusion The presence of Abu in a plant lectin structure strongly indicates the ability of lectins on carrying secondary metabolites. Comparison of the amino acids composing the site with other legume lectins revealed that this site is conserved, providing an evidence of the biological relevance of this site. This new action of lectins strengthens their role in defense mechanisms in plants.

  1. Genetic control of the variable innate immune response to asymptomatic bacteriuria.

    Directory of Open Access Journals (Sweden)

    Jenny Grönberg-Hernández

    Full Text Available The severity of urinary tract infection (UTI reflects the quality and magnitude of the host response. While strong local and systemic innate immune activation occurs in patients with acute pyelonephritis, the response to asymptomatic bacteriuria (ABU is low. The immune response repertoire in ABU has not been characterized, due to the inherent problem to distinguish bacterial differences from host-determined variation. In this study, we investigated the host response to ABU and genetic variants affecting innate immune signaling and UTI susceptibility. Patients were subjected to therapeutic urinary tract inoculation with E. coli 83972 to ensure that they were exposed to the same E. coli strain. The innate immune response repertoire was characterized in urine samples, collected from each patient before and after inoculation with bacteria or PBS, if during the placebo arm of the study. Long-term E. coli 83972 ABU was established in 23 participants, who were followed for up to twelve months and the innate immune response was quantified in 233 urine samples. Neutrophil numbers increased in all but two patients and in an extended urine cytokine/chemokine analysis (31 proteins, the chemoattractants IL-8 and GRO-α, RANTES, Eotaxin-1 and MCP-1, the T cell chemoattractant and antibacterial peptide IP-10, inflammatory regulators IL-1-α and sIL-1RA and the T lymphocyte/dendritic cell product sIL-2Rα were detected and variably increased, compared to sterile samples. IL-6, which is associated with symptomatic UTI, remained low and numerous specific immune mediators were not detected. The patients were also genotyped for UTI-associated IRF3 and TLR4 promoter polymorphisms. Patients with ABU associated TLR4 polymorphisms had low neutrophil numbers, IL-6, IP-10, MCP-1 and sIL-2Rα concentrations. Patients with the ABU-associated IRF3 genotype had lower neutrophils, IL-6 and MCP-1 responses than the remaining group. The results suggest that the host

    Full Text Available Abstract Background Catheter-associated urinary tract infection (CAUTI is one of the most common hospital-acquired infections. However, many cases treated as hospital-acquired CAUTI are actually asymptomatic bacteriuria (ABU. Evidence-based guidelines recommend that providers neither screen for nor treat ABU in most catheterized patients, but there is a significant gap between these guidelines and clinical practice. Our objectives are (1 to evaluate the effectiveness of an audit and feedback intervention for increasing guideline-concordant care concerning catheter-associated ABU and (2 to measure improvements in healthcare providers' knowledge of and attitudes toward the practice guidelines associated with the intervention. Methods/Design The study uses a controlled pre/post design to test an intervention using audit and feedback of healthcare providers to improve their compliance with ABU guidelines. The intervention and the control sites are two VA hospitals. For objective 1 we will review medical records to measure the clinical outcomes of inappropriate screening for and treatment of catheter-associated ABU. For objective 2 we will survey providers' knowledge and attitudes. Three phases of our protocol are proposed: the first 12-month phase will involve observation of the baseline incidence of inappropriate screening for and treatment of ABU at both sites. This surveillance for clinical outcomes will continue at both sites throughout the study. Phase 2 consists of 12 months of individualized audit and feedback at the intervention site and guidelines distribution at both sites. The third phase, also over 12 months, will provide unit-level feedback at the intervention site to assess sustainability. Healthcare providers at the intervention site during phase 2 and at both sites during phase 3 will complete pre/post surveys of awareness and familiarity (knowledge, as well as of acceptance and outcome expectancy (attitudes regarding the relevant

    Full Text Available L’antropologia delle emozioni è legata in prevalenza a contesti etnografici descritti, direbbero Gupta e Ferguson (a cura, 1997, come “campi puri”. La maggior parte degli antropologi che lavora sulle emozioni, ha osservato William Reddy (1999, p. 256, utilizzano nelle loro etnografie il presente etnografico e si avvalgono di generalizzazioni che si fondano implicitamente su una concezione dei contesti culturali come ambiti di significati articolati logicamente in un sistema e segnati da confini precisi. Anche quando viene riconosciuta una molteplicità di discorsi contrastanti sulle emozioni, come nell’analisi di Lila Abu-Lughod (1986 delle performance emozionali tra i beduini awlad’ ali, l’ordine culturale all’interno del quale queste collisioni discorsive vengono comunque orchestrate getta un fondato sospetto sull’utilizzabilità degli strumenti di analisi proposti nel “manifesto” di Abu-Lughod e Lutz (a cura, 1990 in contesti meno puri o, forse, meno purificati.

    We present a measurement of the energy spectrum of ultra-high-energy cosmic rays performed by the Telescope Array experiment using monocular observations from its two new FADC-based fluorescence detectors. After a short description of the experiment, we describe the data analysis and event reconstruction procedures. Since the aperture of the experiment must be calculated by Monte Carlo simulation, we describe this calculation and the comparisons of simulated and real data used to verify the validity of the aperture calculation. Finally, we present the energy spectrum calculated from the merged monocular data sets of the two FADC-based detectors, and also the combination of this merged spectrum with an independent, previously published monocular spectrum measurement performed by Telescope Array's third fluorescence detector (Abu-Zayyad {\\it et al.}, {Astropart.

In contrast to uropathogenic E. coli (UPEC), which causes symptomatic urinary tract infections (UTI), very little is known about the mechanisms by which these strains colonize the human urinary tract...... to conventional therapy. Colonization with strain 83972 appears to prevent infection with UPEC strains in such patients despite the fact that this strain is unable to express the primary adhesins involved in UTI, viz.

    Chicken parvovirus (ChPV) is one of the causative agents of viral enteritis. Recently, the genome of the ABU-P1 strain of ChPV was fully sequenced and determined to have a distinct genomic composition compared with that of vertebrate parvoviruses. However, no comparative sequence analysis of coding regions of ChPVs was possible because of the lack of other sequence information. In this study, we obtained the nucleotide sequences of all genomic coding regions of three ChPVs by polymerase chain reaction using 13 primer sets, and deduced the amino acid sequences from the nucleotide sequences. The non-structural protein 1 (NS1) gene of the three ChPVs showed 95.0 to 95.5% nucleotide sequence identity and 96.5 to 98.1% amino acid sequence identity to those of NS1 from the ABU-P1 strain, respectively, and even higher nucleotide and amino acid similarities to one another. The viral proteins (VP) gene was more divergent between the three ChPV Korean strains and ABU-P1, with 88.1 to 88.3% nucleotide identity and 93.0% amino acid identity. Analysis of the putative tertiary structure of the ChPV VP2 protein showed that variable regions with less than 80% nucleotide similarity between the three Korean strains and ABU-P1 occurred in large loops of the VP2 protein believed to be involved in antigenicity, pathogenicity, and tissue tropism in other parvoviruses. Based on our analysis of full-length coding sequences, we discovered greater variation in ChPV strains than reported previously, especially in partial regions of the VP2 protein.

    Full Text Available Objective: To study Ulva linza (U. linza as macro-alga exposed to different levels of ionizing radiation from the natural background of radioactivity. Methods: Samples of U. linza were collected from two different habitats at the two terminals of the rocky shore of Abu Qir Bay, Alexandria, Egypt. The western terminal at Abu Qir represented an area of normal background radiation while the eastern terminal at Rosetta represented an area of relatively high background radiation. Distinguishing between the algae grown in areas of relatively high and normal background radiation was investigated by using different indicators. Moreover, the ambient water quality was measured and the concentrations of natural radionuclides (238U, 232Th and 40K bio-accumulated in the tested macro-alga were detected. Results: The algae naturally exposed to radionuclides (238U series, 232Th series and 40K were investigated. Radiation dose rates in U. linza inhabiting in Rosetta and Abu Qir were calculated as 70.12 and 42.67 nGy/h, respectively. Chemical analysis of algal samples demonstrated that total pigment contents were 2.21 and 2.19 mg/g on a fresh weight basis for U. linza inhabiting in Rosetta and Abu Qir, respectively. Fatty acid compositions showed comparable profiles for both algal samples with saturated fatty acids as major component. The results of protein profiles confirmed slight differential expression in protein bands. Sequence-related randomly amplified polymorphic DNA provided evidence that both samples were strongly similar. By using transmission electron microscopy, no obvious ultra structural changes in the examined cells were observed. Conclusions: These experimental results demonstrate that radiation doses are not high enough to cause damage or manifest any significant variation in Ulva tissues.

  11. Measurements of the Natural Radioactivity along Wadi Nugrus, Egypt

    International Nuclear Information System (INIS)

    Representative samples of the stream sediments from different locations at Wadi Nugrus area, SED, have been investigated radiometrically using gamma-ray spectrometer (NaI-detector). Their concentration of 238U, 232Th and 40K radionuclides and the related radiation hazard indices were estimated. The activity concentration of 238U ranges from 24.7 (Bq/kg) at the location interfacing Wadi El Nom and at Jazzerat Nugrus to 86.45 (Bq/kg) at the location interfacing Wadi Abu Rsheid with an average of 43.91 (Bq/kg). The activity concentration of 232Th ranges from 20.3 (Bq/kg) at Jazzerat Nugrus and at the location along Wadi El Gemal to 48.72 (Bq/kg) at the location interfacing Wadi Abu Rsheid with an average of 26.62 (Bq/kg). Finally, the activity concentration of 40K ranges from 306.7 (Bq/kg) at the location along Wadi El Gemal to 626 (Bq/kg) at the upstream of Wadi Nugrus, at the upstream of Jazzerat Nugrus and at the location interfacing Wadi Abu Rsheid with an average of 467.4 (Bq/kg). The γ-absorbed dose rates of the stream sediments range between 37.44 n Gy/h at jazeerat Nugrus which is located at the middle of the Wadi Nugrus and 96.08 n Gy/h in the Wadi at the location facing the opening of Wadi Abu Rusheid with an average of 56.47 n Gy/h. The γ-absorbed dose rate in the air at Madinat Nugrus is 59.96 n Gy/h. These dose rates are consistent with the accepted worldwide average of 59 n Gy/h for the public. This permits the use of these sediments as building materials in any probable development projects at this area

    This paper aims at claiming the ancestral wisdom of indigenous people in the health area. It analyzes how health has been commodified in the interest of large companies (particularly those related to the pharmaceutical industry) to the detriment of a holistic definition of wellness through education. Furthermore, the concept of health as a right disagrees with such commodification or sale to the highest bidder, which prompts dehumanization of health services and public misinformation. The abu...

  16. Dynamically-expressed prion-like proteins form a cuticle in the pharynx of Caenorhabditis elegans

    Full Text Available In molting animals, a cuticular extracellular matrix forms the first barrier to infection and other environmental insults. In the nematode Caenorhabditis elegans there are two types of cuticle: a well-studied collagenous cuticle lines the body, and a poorly-understood chitinous cuticle lines the pharynx. In the posterior end of the pharynx is the grinder, a tooth-like cuticular specialization that crushes food prior to transport to the intestine for digestion. We here show that the grinder increases in size only during the molt. To gain molecular insight into the structure of the grinder and pharyngeal cuticle, we performed a microarray analysis to identify mRNAs increased during the molt. We found strong transcriptional induction during the molt of 12 of 15 previously identified abu genes encoding Prion-like (P glutamine (Q and asparagine (N rich PQN proteins, as well as 15 additional genes encoding closely related PQN proteins. abu/pqn genes, which we name the abu/pqn paralog group (APPG genes, were expressed in pharyngeal cells and the proteins encoded by two APPG genes we tested localized to the pharyngeal cuticle. Deleting the APPG gene abu-14 caused abnormal pharyngeal cuticular structures and knocking down other APPG genes resulted in abnormal cuticular function. We propose that APPG proteins promote the assembly and function of a unique cuticular structure. The strong developmental regulation of the APPG genes raises the possibility that such genes would be identified in transcriptional profiling experiments in which the animals' developmental stage is not precisely staged.

    The Campanian-Maastrichtian phosphatic deposits in Egypt,called the Duwi Forma-tion,comprise a part of the extensive Middle East to North African phosphogenic province of Late Cretaceous to Paleogene age.The province holds the greatest accumulation of phosphorites in the geological history,possibly in excess of 70 billion metric tons.The phosphate resources in Egypt alone exceed 3 billion metric tons.Two-third of these three billions occur only in the Abu-Tartur area.Among the phosphorite deposits in Egypt,the phosphorites of the Abu-Tartur area are characterized by high contents of iron ranging from 3% to 7% with an average of 5%.The detailed mineralogical and geochemical studies on the Abu-Tartur phosphorites revealed that iron is found in the form of pyrite,ankerite,clay minerals,microinclusions,and iron oxide.Pyrite,which is the major fraction,occurs as filling cement and partial to complete teplacement of phosphatic grains and confined to the fresh phosphorites while iron oxide occurs as cryp-tocrystalline aggregates of red to brown particles and is confined to the weathered outcrops.Ex-clusive relations between pyrite in the fresh phosphorite samples inside the Abu-Tartur mine and iron oxide in the equivalent horizon of the weathered exposure indicated that iron oxide was formed by the oxidation of pyrite as a result of weathering.All of these forms harm the quality of ore,manufacturing processes,and the produced phosphoric acid and fertilizers.

  5. Tycho Brahe, Abū Macshar, and the comet beyond Venus (ninth century A.D.)

    From his observations of the A.D. 1572 super-nova and the A.D. 1577 comet, Tycho Brahe concluded that such transient celestial objects are outside the Earth's atmosphere, and he quoted the 9th century A.D. Persian astrologer and astronomer Abu Mashar: Dixit Albumasar, Cometa supra Venerem visus fuit, i.e. that he had reported much earlier that comets were seen beyond Venus. However, even from a more detailed Latin translation, the observations and logic behind Abu Mashar's conclusion were not understandable. We present here the original Arabic text (MS Ankara, Saib 199) together with our translation and interpretation: Abu Mashar reported that he had observed Venus in (or projected onto) the tail of a comet and concluded that the comet was behind Venus, because he had observed the extinction of Venus due to the cometary tail to be negligible (light of Venus was unimpaired). He then concluded that the comet would be located behind Venus. He also mentioned that others had observed Jupiter and Saturn in cometary tails, so that those comets would even be located beyond those two outer planets - in the sphere of the stars. The dates of the observed close conjunctions were not mentioned; using known orbital elements for a few comets, we found a few close conjunctions between comets and planets from A.D. 770 to 868, but we cannot be sure regarding which conjunctions were reported. While the argument of Abu Mashar is not correct (as cometary tails are optically thin), parts of the conclusion - namely that comets are outside the Earth atmosphere and beyond the moon - is correct. This may have helped Tycho Brahe to come to his revolutionary conclusion.

    Gyrodactylus aff. mugili Zhukov, 1970 (Monogenoidea: Gyrodactylidae) is recorded and described from the gill lamellae of 11 of 35 greenback mullet, Chelon subviridis (Valenciennes) (minimum prevalence 31%), from the brackish waters of the Shatt Al-Arab Estuary in southern Iraq. The gyrodactylid was also found on the gill lamellae of one of eight Speigler's mullet, Valamugil speigleri (Bleeker), from the brackish waters of the Shatt Al-Basrah Canal (minimum prevalence 13%). Fifteen Klunzinger's mullet, Liza klunzingeri (Day), and 13 keeled mullet, Liza carinata (Valenciennes), collected and examined from southern Iraqi waters, were apparently uninfected. The gyrodactylids from the greenback mullet and Speigler's mullet were considered to have affinity to G. mugili Zhukov, 1970, and along with G. mugili may represent members of a species complex occurring on mullets in the Indo-Pacific Region. A single damaged gyrodactylid from the external surfaces of the abu mullet, Liza abu (Heckel), was insufficient for species identification. Previously identified species of Gyrodactylus recorded on L. abu in Iraq by various authors were considered possible misidentifications or accidental infections. PMID:24471286

    Full Text Available Solid state nuclear track detectors are used in very broad fields of technical applications and successfully applied in different areas of environmental physics and geophysics. Radon concentration and surface exhalation rate for phosphate samples from El-Sebaeya and Abu-Tartur, Egypt, were measured using nuclear tracks detectors from types CR-39 and LR-115. The average values of radon concentration are 12711.03 and 10925.02 Bqm−3 in El-Sebaeya area using CR-39 and LR-115 detectors, respectively. Also the average values of radon concentration are 15824.16 and13601.48 Bqm−3 in Abu-Tartur area using CR-39 and LR-115 detectors, respectively. From the obtained results we can conclude that the average values of radon concentration in Abu-Tartur are higher than El-Sebaeya. The present study is important to detect any harmful radiation which, can be used as reference information to assess any changes in the radioactive background level in the surrounding environment.

  11. Network reconfiguration for loss reduction in electrical distribution system using genetic algorithm

    International Nuclear Information System (INIS)

    Distribution system is a critical links between the utility and the nuclear installation. During feeding electricity to that installation there are power losses. The quality of the network depends on the reduction of these losses. Distribution system which feeds the nuclear installation must have a higher quality power. For example, in Inshas site, electrical power is supplied to it from two incoming feeders (one from new abu-zabal substation and the other from old abu-zabal substation). Each feeder is designed to carry the full load, while the operator preferred to connect with a new abu-zabal substation, which has a good power quality. Bad power quality affects directly the nuclear reactor and has a negative impact on the installed sensitive equipment's of the operation. The thesis is Studying the electrical losses in a distribution system (causes and effected factors), feeder reconfiguration methods, and applying of genetic algorithm in an electric distribution power system. In the end, this study proposes an optimization technique based on genetic algorithms for distribution network reconfiguration to reduce the network losses to minimum. The proposed method is applied to IEEE test network; that contain 3 feeders and 16 nodes. The technique is applied through two groups, distribution have general loads, and nuclear loads. In the groups the technique applied to seven cases at normal operation state, system fault condition as well as different loads conditions. Simulated results are drawn to show the accuracy of the technique.

    Full Text Available Abstract Background Clinical dogma is that healthy urine is sterile and the presence of bacteria with an inflammatory response is indicative of urinary tract infection (UTI. Asymptomatic bacteriuria (ABU represents the state in which bacteria are present but the inflammatory response is negligible. Differentiating ABU from UTI is diagnostically challenging, but critical because overtreatment of ABU can perpetuate antimicrobial resistance while undertreatment of UTI can result in increased morbidity and mortality. In this study, we describe key characteristics of the healthy and ABU urine microbiomes utilizing 16S rRNA gene (16S rDNA sequencing and metaproteomics, with the future goal of utilizing this information to personalize the treatment of UTI based on key individual characteristics. Methods A cross-sectional study of 26 healthy controls and 27 healthy subjects at risk for ABU due to spinal cord injury-related neuropathic bladder (NB was conducted. Of the 27 subjects with NB, 8 voided normally, 8 utilized intermittent catheterization, and 11 utilized indwelling Foley urethral catheterization for bladder drainage. Urine was obtained by clean catch in voiders, or directly from the catheter in subjects utilizing catheters. Urinalysis, urine culture and 16S rDNA sequencing were performed on all samples, with metaproteomic analysis performed on a subsample. Results A total of 589454 quality-filtered 16S rDNA sequence reads were processed through a NextGen 16S rDNA analysis pipeline. Urine microbiomes differ by normal bladder function vs. NB, gender, type of bladder catheter utilized, and duration of NB. The top ten bacterial taxa showing the most relative abundance and change among samples were Lactobacillales, Enterobacteriales, Actinomycetales, Bacillales, Clostridiales, Bacteroidales, Burkholderiales, Pseudomonadales, Bifidobacteriales and Coriobacteriales. Metaproteomics confirmed the 16S rDNA results, and functional human protein

    Full Text Available The abundance of onchocerciasis vectors affects the epidemiology of disease in Sudan, therefore, studies of vector dynamics are crucial for onchocerciasis control/elimination programs. This study aims to compare the relative abundance, monthly biting-rates (MBR and hourly-based distribution of onchocerciasis vectors in Abu-Hamed and Galabat foci. These seasonally-based factors can be used to structure vector control efforts to reduce fly-biting rates as a component of onchocerciasis elimination programs.A cross-sectional study was conducted in four endemic villages in Abu-Hamed and Galabat foci during two non-consecutive years (2007-2008 and 2009-2010. Both adults and aquatic stages of the potential onchocerciasis vector Simulium damnosum sensu lato were collected following standard procedures during wet and dry seasons. Adult flies were collected using human landing capture for 5 days/month. The data was recorded on handheld data collection sheets to calculate the relative abundance, MBR, and hourly-based distribution associated with climatic factors. The data analysis was carried out using ANOVA and Spearman rank correlation tests.Data on vector surveillance revealed higher relative abundance of S. damnosum s.l. in Abu- Hamed (39,934 flies than Galabat (8,202 flies. In Abu-Hamed, vector populations increased in January-April then declined in June-July until they disappeared in August-October.

    International Nuclear Information System (INIS)

    Three Arab countries export natural gas up to day: Algeria, United Arab Emirates and Libya. Algerian exports will get 60 milliards cubic metres from now to the year 2000, in fact, around 1995-1996. According to the Organization of oil exporting arab countries, other arab countries exports would be multiplied by a factor eight between 1992 and 2000, going up from 4.7 milliards cubic metres to about 40 milliards cubic metres at the end of century, with Qatar and Oman coming on the worldwide market and sales increasing of Abou Dhabi. If these expectations came true, Arab natural gas exports would add up to 100 milliards cubic metres in the year 2000, against 40 milliards cubic metres last year (1992)

    2005-12-01

    Three geo-archaeological sites at the North Coast and Alexandria, namely, the Alexandria wall (El Shalalat Park site), Abu Soir temple, and Marina excavations, were investigated to determine the negative impact of a salty environmental condition. The monuments suffer from rock decay of different rates. The geo-archaeological sites were built mainly from oolitic limestone blocks (i.e., the Alexandria wall at the El Shalalat Park site and Abu Soir temple) or excavated on them (i.e., Marina excavations). Field inspection and a lab analysis were carried out to understand the weathering mechanism. Salt weathering criteria such as disintegration, pitting, scaling, exfoliation, and honeycomb are observed on the Alexandria wall and upper parts of the Abu Soir temple, while dangerous cracks are detected on the Marina excavation tombs. The petrographic study of the oolitic limestone samples shows that they consist mainly of oolities and drusy sparite as a cement (oolitic grainstone). Some oolities have quartz grains as nuclei. Hydrochemical analysis shows that the total dissolved salts of extracted solutions of the North Coast quarry samples range from 539 to 686 ppm and dramatically increase (i.e., ten times) for extracted solutions from monument samples, ranging from 5395 to 6880 ppm. The dominant cation is sodium while the dominant anion is chlorine. Acid insoluble residue analysis shows that the carbonate content ranges from 89.2% to 96.4% for fresh samples from quarries and from 9.2% to 94.8% for weathered monument samples. The weight loss of the quarry oolitic limestone samples range from 30.7% to 32.7% and its physical and mechanical properties become worse after being subjected to 15 cycles of a durability simulation soundness test (using a sodium sulphate solution). Our main recommendations are to use suitable grouting for binding the cracks, high durability reconstruction rocks, and suitable cleaning methods to remove salts from the monuments.

    Full Text Available Abstract Background Semi-quantitative bacteruria counts (s-QBC are important in the diagnosis of urinary tract infection (UTI due to most uropathogens. The prognostic value of s-QBC for diagnosis of UTI due to group B streptococcus (GBS is unknown. In this study, we assessed the value of s-QBC for differentiating acute GBS UTI from asymptomatic bacteruria (ABU, independent of other potential prognostic indicators. Methods Medical record review and urinalysis (UA values for 1593 patients who had urinary GBS isolated (103 to ≥105 CFU/ml during a four-year period were analyzed using binary logistic regression to determine the predictive values of s-QBC, age, and gender for infection category (acute UTI, ABU based on the clinical diagnosis. Results s-QBC alone had a strong predictive value for infection category but only for ABU. Multivariate logistic regression showed similar predictive power of s-QBC for infection category using age as a co-predictor, which was also independently associated with infection category. Typical s-QBC cut-off values that are commonly used in diagnostic settings had no significant power in predicting infection category. Among other UA measures, proteinuria and hematuria were significantly associated with acute infection. Conclusions Together, these data show that s-QBC is not useful in the differential diagnosis of GBS UTI. Among the patients in this study, age was an equally effective prognostic indicator compared to s-QBC for identifying high- and low-risk patients for acute GBS UTI. Collectively, these findings indicate that age-based associations may be equally as useful as s-QBC for predicting infection category in the setting of adult patients with GBS-positive urine cultures.

    In order to obtain a better dataset for tracking features in near infrared images of Venus, coordinated observations were made from two telescopes in India - the 1m Mt. Abu telescope at Gurushikhar (Location: 24o 39' 8.8" North Latitude, 72o 46' 47.47", 1680 m above MSL, NICMOS III camera, 0.5 arcsec/pixel) and the 2m Optical-Infrared Himalayan Chandra Telescope at Hanle, Ladakh (32o 35' 46" North Latitude and 78o 57' 51" East Longitude, 4500 m above MSL, NIR Camera, 0.21 arcsec/pixel) during 4-10 May 2004 and 6 -10 July 2004 when similar observations were also made from IRTF (Young et al., 2004) and Nordic Optical Telescope (Warell et al., 2004) as well as APO and AAT. Images were obtained at 2.29 micron wavelength using the filters available at the telescopes and show considerable variability from day to day in the atmospheric features. Yet there is enough retention of structural features that suggest a lifetime of 7 days indicating one complete rotation as observed from HCT data taken in May 2004. These features are believed to originate at 52 km level above the Venus surface and the motions are consistent with a rotation rate of 63 m/s at the equator. When combined with those from NOT, IRTF, APO and AAT these observations will yield better information about the circulation at 52 km altitude than has been possible from previous observations. We acknowledge the support and hospitality extended to us to obtain these observations by the staff of Mt. Abu and the Chandra telescopes, in particular Rajesh Shat and Jinesh Jain. Mt. Abu Telescope is operated by Physical Research Laboratory (Ahmedabad, India) and the Chandra Telescope is operated by Center for Research and Education in Science and Technology, Indian Institute of Astrophysics (Bangalore, India). Both are supported by the Indian Space Research Organization

    Full Text Available Penelitian bertujuan untuk mengevaluasi perubahan nilai nutrien hijauan sorgum (Sorghum bicolor (L.Moench varietas lokal Rote sebagai pakan ternak ruminansia pada umur panen dan dosis urea yang berbeda,telah dilaksanakan di rumah kaca Laboratorium Hijauan Makanan Ternak dan Pastura Fakultas PeternakanUniversitas Gadjah Mada selama 4 bulan dari tanggal 11 November 2011 hingga 27 Februari 2012. Penelitianini dirancang dengan rancangan acak lengkap pola faktorial dengan 2 faktor perlakuan yaitu umur panen (UPsebagai faktor pertama (UP1= 50 hari, UP2 = 70 hari, dan UP3 = 90 hari dan dosis pupuk urea (P0 = tanpaurea sebagai kontrol, P1 = 50 kg/ha, dan P2 = 100 kg/ha sebagai faktor kedua. Kombinasi perlakuan inidiulang 4 kali. Variabel yang diamati adalah kadar bahan organik (BO, protein kasar (PK, serat kasar (SK,ekstrak eter (EE, bahan ekstrak tanpa N, dan kadar abu (% hijauan sorgum. Hasil penelitian menunjukkan bahwa kadar BO pada UP3P2, UP3P1 dan UP3P0 lebih tinggi dari perlakuan lainnya. Kadar PK tertinggi terdapat pada UP1P2 dan kadar EE tertinggi pada UP3P2. Kadar SK pada UP3P2 dan UP3P0 lebih tinggidan kadar BETN pada UP2P0 dan UP1P1 lebih tinggi dari perlakuan lainnya. UP1P0, UP1P1, dan UP1P2menghasilkan kadar abu yang lebih tinggi dari perlakuan lainnya. Disimpulkan bahwa umur panen 90 hariyang dikombinasikan dengan dosis urea 100 kg/ha menghasilkan nilai nutrien hijauan sorgum terbaik sebagaipakan ruminansia dengan 93,69% kadar BO, 04,45% kadar PK, 08,41% EE, dan 33,14% SK, 47,21% kadarBETN, dan 06,79% kadar abu.
