    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.

    2012-01-01

    Water resources components in Abu Dhabi encompass the conventional sources (rain, springs, ponds and groundwater), and unconventional sources (desalinated water and reclaimed wastewater). The latter represent the most important resources for the time being, since ground water is brackish or salty and the annual rainfall is very low in Abu Dhabi Emirate. Thus conventional water resources are considered under sever depletion and exceeded their natural recharging capacity by 24 times. Per capita...

    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 .

    For more than half a century, the coastal sabkhas of Abu Dhabi have been the focus of intensive research focusing on deposition, early diagenesis and the role of microbial communities. Given all of this activity, it is somewhat surprising that their continental counterparts have been largely neglected with only a brief mention in larger-scale regional studies. This study redresses this imbalance by documenting the sedimentological, mineralogical and early diagenetic characteristics of continental sabkhas that are hosted in the Rub al Khali desert of the United Arab Emirates. During reconnaissance surveys it has been established that organic-rich microbial mats and evaporite minerals, both similar to those observed in the coastal sabkha, also occur in these continental sabkha settings. Satellite imagery was utilised to identify potential field locations for surface and shallow sub surface investigation; subsequent field reconnaissance established the validity of sites in terms of anthropogenic disruption and accessibility. At each site, surface features were described in detail, particularly with reference to any microbial communities or evaporite crusts; sample pits were dug in order to document sub-surface facies geometries and to recover both sediment and pore water samples for subsequent analysis. In each pit, a range of environmental parameters was measured over a prolonged period, including surface and sub-surface temperatures, ground water salinity and dissolved oxygen. Sediment samples were subjected to a range of analyses in order to establish and quantify primary sediment composition and any early diagenetic mineral phases. The results of this study are used to build an atlas of sedimentary structures and textures that are associated with continental sabkha settings. These observations allow us to establish the defining sedimentological and early diagenetic characteristics that can be employed to identify similar depositional environments in ancient

    Abu Dhabi high school students' interest in physics in different contexts was investigated with a survey conducted in connection with the international project, The Relevance of Science Education (ROSE). The sample consisted of 2248 students in public and private schools. Means of most items that belong to the school physics context for both girls and boys were below the score of (3.0). The most interesting topics for both genders were connected with fantasy items. The least interesting items (particularly for girls) were connected with artifacts and technological processes. Girls assigned the highest scores for "why we dream" and "life and death." Boys assigned the highest scores for "inventions and discoveries" and "life outside of earth." The main message of the study is that new curricular approaches and textbooks can be developed through combining technological and human contexts. The implications for curriculum development, teacher professional development programs, and other education strategies in Abu Dhabi are discussed in light of the ROSE survey.

    Middle East respiratory syndrome coronavirus (MERS-CoV) infections sharply increased in the Arabian Peninsula during spring 2014. In Abu Dhabi, United Arab Emirates, these infections occurred primarily among healthcare workers and patients. To identify and describe epidemiologic and clinical characteristics of persons with healthcare-associated infection, we reviewed laboratory-confirmed MERS-CoV cases reported to the Health Authority of Abu Dhabi during January 1, 2013–May 9, 2014. Of 65 case-patients identified with MERS-CoV infection, 27 (42%) had healthcare-associated cases. Epidemiologic and genetic sequencing findings suggest that 3 healthcare clusters of MERS-CoV infection occurred, including 1 that resulted in 20 infected persons in 1 hospital. MERS-CoV in healthcare settings spread predominantly before MERS-CoV infection was diagnosed, underscoring the importance of increasing awareness and infection control measures at first points of entry to healthcare facilities.

    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.

  14. Estimation of compressional seismic wave attenuation of carbonate rocks in Abu Dhabi, United Arab Emirates

    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.

    Full Text Available The purpose of this article is to provide a practical overview of the recently initiated modernization of Abu Dhabi’s judicial system. Beginning in 2007, Abu Dhabi’s Government launched a comprehensive effort to transform the Emirate’s judicial system. While the implementation of these reforms is ongoing, with the adoption of the law in May 2007 establishing the new judicial architecture the initial phase of the modernization program is already complete. The restructuring process encompasses court management and administration reform, a new judicial training regime, a redesigned organizational structure for the Emirate’s Judicial Department and courts, and the establishment of a system-wide strategic planning and budgeting process. Many of these initiatives are supported by applying advanced IT-based applications. Given the early achievements and ambitious broader aims of the restructuring process, Abu Dhabi’s example is relevant not only to the other Emirates within the Federal UAE system, but also within the context of the wider Middle East region.

    Zonation of Recent mangrove environments can be defined using benthic foraminifera, however, little is known about foraminifera from mangrove environments of the Persian/Arabian Gulf. The objective of this study is to produce a detailed micropaleontological and sedimentological analysis to identify foraminiferal associations from 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 benthic foraminifera in different sedimentary facies in the mangal and in the surrounding natural environments of the upper and lower intertidal area (mud flats and channels). A 100 m transect across a natural channel in a mangal on the eastern side of Abu Dhabi Island was sampled in detail for sedimentological and foraminiferal analysis. Forty-seven samples were collected at 2 meter intervals along the transect in a number of different sedimentary facies including; fine sediment in areas exposed during low tide and close to mangrove trees (Avicennia marina), fine sediment rich in leaf material, coarse sediment in channels, and coarse sediments with a shell lag. At each sampling location environmental parameters were recorded, including water depth, salinity, temperature and pH. Samples collected for foraminiferal analysis were stained in rose Bengal in order to identify living specimens. Samples collected on the mud flat at the margin of the channel show a living foraminiferal assemblage characterised by abundant foraminifera belonging to the genera Ammonia, Elphidium, Cribroelphidium, Triloculina, Quinqueloculina, Sigmoilinita, Spiroloculina, Peneroplis and Spirolina. Samples collected in the lower (wet) intertidal area close to Avicennia marina roots, presented a low-diversity assemblage mostly comprising small-sized opportunistic foraminifera of the genera Ammonia and Cribroelphidium along with rare Triloculina and

    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

    Hazard vulnerability analysis (HVA) is used to risk-stratify potential threats, measure the probability of those threats, and guide disaster preparedness. The primary objective of this project was to analyse the level of disaster preparedness in public hospitals in the Emirate of Abu Dhabi, utilising the HVA tool in collaboration with the Disaster Medicine Section at Harvard Medical School. The secondary objective was to review each facility's disaster plan and make recommendations based on the HVA findings. Based on the review, this article makes eight observations, including on the need for more accurate data; better hazard assessment capabilities; enhanced decontamination capacities; and the development of hospital-specific emergency management programmes, a hospital incident command system, and a centralised, dedicated regional disaster coordination centre. With this project, HVAs were conducted successfully for the first time in health care facilities in Abu Dhabi. This study thus serves as another successful example of multidisciplinary emergency preparedness processes. © 2014 The Author(s). Disasters © Overseas Development Institute, 2014.

We completed a cross-sectional survey consisting of structured site observations and in-person interviews of businesses in New York City, Abu Dhabi and Dubai identified using Google, Yelp, Timeout Dubai and Timeout Abu Dhabi and neighbourhood visits in 2014. Regular customers made up 59% of customers. Franchises or chains were 28% of businesses. Waterpipes made up 39% of sales with 87% of businesses offering food within their menu. Flavoured tobacco made up 94% of sales. Discounts were offered by 47% of businesses and 94% of businesses used advertising, often through social media. The market consists of largely independent businesses, with a large regular customer base, frequently offering diversified services beyond waterpipes. These businesses advertise using both traditional and social media. The economics of waterpipe businesses is very different from the economics of cigarettes, and unique regulatory strategies are needed to control this epidemic.

    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.

    Marine carbonate firm- and hardgrounds have been described from the Precambrian to the recent sedimentary archive. In comparison to the numerous publications dealing with fossil case examples, well-constrained studies of shoalwater hardground formation from modern (sub)tropical seas are comparably scarce. This comes as a surprise as only modern depositional environments offer direct insight into the plethora of environmental, geochemical, kinetic, and biological parameters that affect these features at formation and during diagenetic pathways. Here, we present the first results of a combined field and laboratory study with focus on firm- to hardgrounds (also termed "discontinuity" in the sense of a catch-it-all term) forming both in the shallow inner lagoon and the outer lagoon ooid shoals of the Abu Dhabi barrier-island complex. Essentially, the discontinuities found represent sub-grounds in the sense that they form a few centimetres beneath the sediment surface. Sub-grounds in the outer lagoon ooid shoals are cemented by characteristic needle-shaped aragonite crystals and essentially represent lithified crab burrows. In contrast, sub-grounds in the inner lagoon of Abu Dhabi form brittle intervals, perhaps 5 cm in thickness, that are cemented by platy aragonitic crystals that show uncommon morphologies. Botryoids are abundant and generally seem to affect crystal morphologies. First evidence suggests that these features form below the uppermost oxic layer of pore fluids in the shallow sedimentary column. These findings are placed in context with temporally-resolved data on sea and porewater chemistry.

    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

    There is a close link between fractures network and fluids circulation so information about nature and geometry of fractures in the reservoir zone is benificial for the petroleum industry. However the immaturity of the methodology and the complication of fractures network in some reservoirs like those of Abu Dhabi oil fields, make getting such information challenging. Since several studies showed the close link between physical properties of the subsurface and seismic wave attenuation (eg. Müller et al. 2010), we use this parameter in this study to assess its potentiality on fractures detection and characterization, even though its use is not common for reservoir characterization and even less for fractures characterization. To get an accurate attenuation profiles, we use a robust methods recently developed to estimate accurately attenuation from Vertical Seismic Profiling (VSP) (Matsushima et al. 2016) and sonic waveforms (Suziki and Matsushima 2013) in the reservoir zones. The data were acquired from many wells located in offshore and onshore oil fields of Abu Dhabi region. The subsurface of this region is mainly composed of carbonate rocks, such media are known to be highly heterogeneous. Scattering and intrinsic attenuation profiles were compared to interpreted fractures by using Formation Micro-imager (FMI). The comparison shows a correlation between these two parameters and fractures characteristic, such as their density and dipping. We also performed Alford rotation on dipole data to estimate the attenuation from fast and slow shear waveforms. The anisotropy is proportional to the dispersion of the points plotted from the ratio between the intrinsic attenuation of fast and slow shear over the depth, from the line (Qslow /Qfast=1), which corresponds to the isotropic case. We noticed that the zones with low fractures density display less dispersion than those of high density. Even though our results show potentiality of the attenuation for fractured

    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

    Full Text Available The fishing industry in Abu-Dhabi, United Arab Emirates (UAE, plays an important role in diversifying food sources in order to enhance national food security. The fishing industry is facing an increasing risk that may impact the sustainability (i.e., quantity and quality of the fish caught and consumed in the UAE. Therefore, the main objective of this study is to analyze common Abu-Dhabi fishing management alternatives using various stochastic dominance techniques (i.e., first/second degree stochastic dominance, stochastic dominance with respect to a function and stochastic efficiency with respect to a function to assess the risk facing UAE fishermen. The techniques represent a risk assessment continuum, which can provide a ranking of management alternatives to improve decision making outcomes and help maintain long-term UAE fishing sustainability. Data for the stochastic dominance analyses were obtained from a cross-sectional survey conducted through face-to-face interviews of Abu Dhabi, UAE, fishermen. Analysis of fishing methods, trap sizes and trap numbers using stochastic efficiency with respect to a function (SERF showed that fishermen efficient practices were not the same for risk-neutral fishermen compared to risk averse fishermen. Overall, the stochastic dominance results illustrated the importance of considering both attitude towards risk and economic inefficiencies in managing UAE fishery practices and designing successful fishery policies, as well as improving decision-making at the fishermen level.

    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 present study is on the aerosol optical and radiative properties in the short-wave radiation and its climate implications at the arid city of Abu Dhabi (24.42 ∘N, 54.61 ∘E, 4.5 m MSL), in the United Arab Emirates. The direct aerosol radiative forcings (ARF) in the short-wave region at the top (TOA) and bottom of the atmosphere (BOA) are estimated using a hybrid approach, making use of discrete ordinate radiative transfer method in conjunction with the short-wave flux and spectral aerosol optical depth (AOD) measurements, over a period of 3 years (June 2012-July 2015), at Abu Dhabi located at the south-west coast of the Arabian Gulf. The inferred microphysical properties of aerosols at the measurement site indicate strong seasonal variations from the dominance of coarse mode mineral dust aerosols during spring (March-May) and summer (June-September), to the abundance of fine/accumulation mode aerosols mainly from combustion of fossil-fuel and bio-fuel during autumn (October-November) and winter (December-February) seasons. The monthly mean diurnally averaged ARF at the BOA (TOA) varies from -13.2 Wm-2 (˜-0.96 Wm-2) in November to -39.4 Wm-2 (-11.4 Wm-2) in August with higher magnitudes of the forcing values during spring/summer seasons and lower values during autumn/winter seasons. The atmospheric aerosol forcing varies from + 12.2 Wm-2 (November) to 28.2 Wm-2 (June) with higher values throughout the spring and summer seasons, suggesting the importance of mineral dust aerosols towards the solar dimming. Seasonally, highest values of the forcing efficiency at the surface are observed in spring (-85.0 ± 4.1 W m-2 τ -1) followed closely by winter (-79.2 ± 7.1 W m-2 τ -1) and the lowest values during autumn season (-54 ± 4.3 W m-2 τ -1). The study concludes with the variations of the atmospheric heating rates induced by the forcing. Highest heating rate is observed in June (0.39 K day -1) and the lowest in November (0.17 K day -1) and the temporal

    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.

    A decision support system (DSS) was used at the Abu Dhabi distribution company (ADDC) in the United Arab Emirates to help planners and managers choose and implement the most reliable and economic network configuration. The impact of using a Geographical Information System (GIS) and Distribution Management System (DMS) on the reliability and cost of alternative network-distribution systems was also examined. The study took into account reliability costs as well as maintenance and investment costs to achieve the optimal feeder automation plan for the best transmission-system reliability. The planning of a distribution system involves two aspects, notably reliability and capacity of the system to meet load growth. Examples of improving distribution network performance after implementing GIS and DMS technologies were presented. The system reliabilities were measured by the System Average Interruption Duration Index (SAIDI), System Average Interruption Frequency Index (SAIFI), and the Un-served KWh per Customer. The results showed that GIS and DMS technologies can improve system reliability indices by up to 45 per cent depending on the network architecture, with less than 10 per cent increase in related investment costs. 26 refs., 1 tab., 5 figs.

    This study assessed the knowledge and practices about folic acid in pregnancy among pregnant women attending 2 main maternal and child health centres in Abu Dhabi. The majority of the 277 interviewed mothers (79.1%) had heard of folic acid and 46.6% had accurate knowledge about the role of folate in preventing neural tube defects. There were good practices regarding folate supplementation in the current pregnancy; most of the interviewed mothers took it daily and in the recommended dose. However, only a minority took it prior to pregnancy. Education, irrespective of age or parity, was the major factor determining better knowledge of folic acid in pregnancy.

    Microbial mats are organo-sedimentary structures that are typically found in areas with extreme environmental conditions. Since these ecosystems are considered to be representative of the oldest forms of life on Earth, the study of microbial mats can inform our understanding of the development of life early in the history of our planet. In this study, we used hypersaline microbial mats from the Abu Dhabi sabkha (coastal salt flats). Cores of microbial mats (ca. 90 mm depth) were collected within an intertidal region. The cores were sliced into layers 2-3 mm thick and genomic DNA was extracted from each layer. A fragment of the 16S rRNA encoding gene was amplified in all DNA extracts, using barcoded primers, and the amplicons sequenced with the Ion Torrent platform to investigate the composition of the microbial communities down the depth of the cores. Preliminary results revealed a high proportion of Archaea (15.5-40.8% abundance) in all layers, with Halobacteria appearing to be more significant in the first 40 mm (0.4-10.3% of the total microbial community). Members of the Deltaproteobacteria were dominant in almost all layers of the microbial mat (≤ 48.6% relative abundance); however this dominance was not reflected in the first 8 mm, where the abundance was less than 2%. Chloroflexi and Anaerolinea, representing 93% of bacterial abundance, dominated the first 8 mm depth and decreased at greater depth (≤ 3% relative abundance). Cyanobacteria were found only in the top 10 mm, with unexpected low abundance (≤ 3% of the total number of reads). These results show a vertical zonation of microbial communities and processes in the microbial mats. Further analyses are underway to investigate if these patterns are repeated at other sites along a transect of the sabkha, and to relate the microbial composition to the physical-chemical conditions of the sites.

The present study, being a component of this programme, intends to understand the influence of chemical parameters such as dissolved oxygen, nitrate, nitrite, phosphate, ammonia and total organic carbon on Artemia biomass and cyst production at different sites of the Al Wathba Lake. The study was carried out by sampling lake water quarterly for a period of 5 years from 2010 to 2014. The Artemia population was found to have direct impact of the above mentioned parameters on its abundance. The abundance was highest during the year 2010. Further, temperature, dissolved oxygen, nitrate and cadmium were found to be the most crucial parameters for production of Artemia. The study further aimed to determine the significant relationship between physico-chemical parameters and Artemia sp. population dynamics and cyst production.

    This paper presents data from the first major survey of the diversity, biology and fisheries of elasmobranchs in the Persian (Arabian) Gulf. 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 (shark species) and include some notable differences from other locations in the Indo-West Pacific Ocean. A number of concerns regarding the sustainability of the fishery were highlighted by this study, notably that most of the batoid species recorded are classed by the IUCN Red List as vulnerable, endangered, data deficient or not evaluated. Despite their considerable elasmobranch landings, none of the three countries sampled have developed a 'Shark Plan' as encouraged to do so under the FAO International Plan of Action: Sharks. Furthermore, Kuwait and Qatar currently report zero or no elasmobranch landings to the FAO.

    This study assesses self-reported tobacco use prevalence (cigarette, water-pipe, and medwakh) among applicants to Abu Dhabi's Premarital Screening program during 2011. Premarital Screening data reported to the Health Authority - Abu Dhabi from April to December 2011 were utilized to estimate tobacco use prevalence among applicants. Smoking prevalence was examined by nationality, age group and gender. Overall, 24.7% of Premarital Screening Program applicants were current smokers; 11.5% smoked cigarettes, 5.9% smoked medwakh (hand-held pipe), 4.8% smoked water-pipe and 2.5% smoked a combination (more than one type). Men (19.2%) were more likely than women (3.5%) to be current cigarette smokers. Women were much less likely to smoke medwakh (0.1%) than men (11.5%), with male UAE Nationals having the highest medwakh smoking prevalence (16.1%). The overall prevalence of water-pipe smoking was 6.8% among men and 2.8% for women with the highest water-pipe smoking prevalence (10.2%) among Arab expatriate men. Variations in tobacco use prevalence among Premarital Screening Program applicants reflect preferences for different modes of tobacco consumption by nationality, age group and gender. Enforcement of tobacco control laws, including implementation of clean indoor air laws and tobacco tax increases, and targeted health education programs are required to reduce tobacco consumption and concomitant tobacco-related morbidity and mortality.

    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

    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

    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

    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.

    In the modern hypersaline carbonate lagoon and sabkha sedimentary environments of Abu Dhabi (United Arab Emirates), three types of organic matter originate respectively from microbial mat, Avicennia mangrove, and Halodule lagoonal seagrass. The study of recent sedimentary processes and cross sections through the sabkha sediments leads to the definition of organo-sedimentary facies based on geochemical and sedimentological criteria. This permits the construction of an organo-sedimentary sequence which expresses the Holocene sedimentary record involving a transgressive and a regressive sequence. The various organic facies occur in both sequences. Heterogeneity within the individual organic facies reflects several factors, including sedimentation dynamics, mineral matrix, oxidation and reduction, and selective organic and mineral diagenesis. These parameters are discussed in terms of depositional environment and location within the organo-sedimentary sequence. Changes in distribution, quantity, and preservation potential of the buried organic matter are discussed in terms of sea level changes and sedimentary accretion rates.

    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.

    Strong sensible heat fluxes and deep turbulent mixing - together with marked dustiness and a low substrate water content - represent a characteristic signature in the boundary layer over hot deserts, resulting in "thicker" mixing layers and peculiar optical properties. Beside these main features however, desert ABLs present extremely complex local structures that have been scarcely addressed in the literature, and whose understanding is essential in modeling processes such as the transport of dust and pollutants, and turbulent fluxes of momentum, heat and water vapor in hyper-arid regions. In this study, we analyze a continuous record of observations of the atmospheric boundary layer (ABL) height from a single lens LiDAR ceilometer operated at Masdar Institute Field Station (24.4oN, 54.6o E, Abu Dhabi, United Arab Emirates), starting March 2013. We compare different methods for the estimation of the ABL height from Ceilometer data such as, classic variance-, gradient-, log gradient- and second derivation-methods as well as recently developed techniques such as the Bayesian Method and Wavelet covariance transform. Our goal is to select the most suited technique for describing the climatology of the ABL in desert environments. Comparison of our results with radiosonde observations collected at the nearby airport of Abu Dhabi indicate that the WCT and the Bayesian method are the most suitable tools to accurately identify the ABL height in all weather conditions. These two methods are used for the definition of diurnal and seasonal climatologies of the boundary layer conditional to different atmospheric stability classes.

    Growing halophytes using Integrated Seawater Agriculture Systems (ISAS) offers a sustainable solution for the generation of biomass feedstock for carbon neutral biofuels - halophytes do not enter the foodchain and they do not compete with food-crops for natural resources. A field demonstration of ISAS in the coastal regions of Abu Dhabi, UAE, scheduled to start in 2013, will likely face a number of region-specific challenges not encountered in past demonstrations of ISAS at coastal locations in Mexico and Eritrea. The arid climate, unique soil chemistry (evaporite deposits, especially gypsum), and hypersaline coastal hydrogeology of Abu Dhabi will affect long-term halophyte agricultural productivity when Arabian Gulf seawater is applied to coastal soils as part of ISAS. Therefore, the changes in irrigation return flow quality and soil chemistry must be monitored closely over time to establish transient salt and water balances in order to assess the sustainability of ISAS in the region. As an initial phase of the ISAS demonstration project, numerical modeling of different seawater loadings onto coastal soils was conducted to estimate the chemical characteristics of soil and the irrigation return flow over time. These modeling results will be validated with field monitoring data upon completion of one year of ISAS operation. The results from this study could be used to (i) determine the optimal saline water loading that the soils at the ISAS site can tolerate, (ii) potential for sodicity of the soil with saline water application, (iii) impacts of land application of saline water on underlying coastal groundwater, and (iv) develop strategies to control soil water activities in favor of halophyte agricultural productivity.

    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.

    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

    Full Text Available To be able to overcome water shortages, Abu Dhabi Emirate started an Aquifer Storage and Recovery (ASR project with desalinated seawater (DSW as source water near Liwa. It is the largest DSW-ASR project in the world (stored volume ~10 Mm3/year, and should recover potable water for direct use. DSW is infiltrated into a desert dune sand aquifer using “sand-covered gravel-bed” recharge basins. In this study, we evaluate the hydrogeological and hydrogeochemical stratification of the (suboxic target aquifer, and water quality changes of DSW during trial infiltration runs. We predict water quality changes of DSW after 824 d of infiltration, during 90 d of intensive recovery (67% recovered without storage (scenario A, as well as after 10 years of storage (scenario B, with significant bubble drift. Monitoring of preceding trials revealed a lack of redox reactions; little carbonate dissolution and Ca/Na exchange; much SiO2 dissolution; a strong mobilization of natural AsO43−, B, Ba, F, CrO42−, Mo, Sr and V from the (suboxic aquifer; and immobilization of PO4, Al, Cu, Fe and Ni from DSW. The Easy-Leacher model was applied in forward and reverse mode including lateral bubble drift, to predict water quality of the recovered water. We show that hydrogeochemical modeling of a complex ASR-system can be relatively easy and straightforward, if aquifer reactivity is low and redox reactions can be ignored. The pilot observations and modeling results demonstrate that in scenario A recovered water quality still complies with Abu Dhabi’s drinking water standards (even up to 85% recovery. For scenario B, however, the recovery efficiency declines to 60% after which various drinking water standards are exceeded, especially the one for chromium.

    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.

    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.

    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 stratigraphic record of a carbonate system is the result of the interplay of several local and global factors that control the physical and the biological responses within a basin. Conceptual models cannot be detailed enough to take into account all the processes that control the deposition of sediments. The evaluation of the key controlling parameters on the sedimentation can be investigated with the use of stratigraphic forward models, that permit dynamic and quantitative simulations of the sedimentary basin infill. This work focuses on an onshore Abu Dhabi field (UAE) and it aims to provide a complete picture of the stratigraphic evolution of Upper Jurassic Arab Formation (Fm.). In this study, we started with the definition of the field-scale conceptual depositional model of the Formation, resulting from facies and well log analysis based on five wells. The Arab Fm. could be defined as a shallow marine carbonate ramp, that ranges from outer ramp deposits to supratidal/evaporitic facies association (from bottom to top). With the reconstruction of the sequence stratigraphic pattern and several paleofacies maps, it was possible to suggest multiple directions of progradations at local scale. Then, a 3D forward modelling tool has been used to i) identify and quantify the controlling parameters on geometries and facies distribution of the Arab Fm.; ii) predict the stratigraphic architecture of the Arab Fm.; and iii) integrate and validate the conceptual model. Numerous constraints were set during the different simulations and sensitivity analyses were performed testing the carbonate production, eustatic oscillations and transport parameters. To verify the geological consistency the 3D forward modelling has been calibrated with the available control points (five wells) in terms of thickness and facies distribution.

    Atmospheric aerosols are known to affect the radiation balance of the Earth-Atmospheric system directly by scattering and absorbing the solar and terrestrial radiation, and indirectly by affecting the lifetime and albedo of the clouds. Continuous and simultaneous measurements of short wave global irradiance in combination with synchronous spectral aerosol optical depth (AOD) measurements (from 340 nm to 1640 nm in 8 channels), for a period of 1 year from June 2012 to May 2013, were used for the determination of the surface direct aerosol radiative forcing and forcing efficiencies under cloud free conditions in Abu Dhabi (24.42°N, 54.61o E, 7m MSL), a coastal location in United Arab Emirates (UAE) in the Arabian Peninsula. The Rotating Shadow band Pyranometer (RSP, LI-COR) was used for the irradiance measurements (in the spectral region 400-1100 nm), whereas the AOD measurements were carried out using CIMEL Sunphotometer (CE 318-2, under AERONET program). The differential method, which is neither sensitive to calibration uncertainties nor model assumptions, has been employed for estimating forcing efficiencies from the changes in the measured fluxes. The forcing efficiency, which quantifies the net change in irradiance per unit change in AOD, is an appropriate parameter for the characterization of the aerosol radiative effects even if the microphysical and optical properties of the aerosols are not completely understood. The corresponding forcing values were estimated from the forcing efficiencies. The estimated radiative forcing and forcing efficiencies exhibited strong monthly variations. The forcing efficiencies (absolute magnitudes) were highest during March, and showed continuous decrease thereafter to reach the lowest value during September. In contrast, the forcing followed a slightly different pattern of variability, with the highest solar dimming during April ( -60 W m-2) and the minimum during February ( -20 W m-2). The results indicate that the aerosol

    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)

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 H{sub 2}. 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 15 USD/m{sup 3}{sub effluent}. With a VFA minimum selling price of 330 USD/t{sub COD}, DF provides a competitive carbon source to sugar. Furthermore, DF is likely to use less energy than conventional processes that produce VFAs, fertilizer and H{sub 2}. This makes DF of OFMSW a promising waste treatment technology and biorefinery platform.

    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.

    AIMS: To investigate the prevalence of undiagnosed type 2 diabetes (T2D) at primary health care (PHC) clinics, and to assess the quality of care of diabetic patients followed at a tertiary hospital diabetes center in Abu Dhabi, United Arab Emirates (UAE). METHODS: Between May 2009 and October 2010, adult patients attending two PHC clinics, and adult diabetic patients attending the diabetes center, were invited to participate in the study. After overnight fast, participants returned for interview and laboratory tests. Undiagnosed T2D was defined by FPG ≥ 7.0 mmol/l or HbA1c ≥ 6.5%. Quality of care was assessed by reported care practices and achievement of internationally recognized targets. RESULTS: Out of 239 patients at PHC clinics without history of T2D, 14.6% had undiagnosed T2D, and 31% had increased risk of diabetes (FPG 5.6-7.0 mmol/l or HbA1c 5.7-6.5%). The independent predictors of undiagnosed T2D were age (adjusted OR per year 1.07, 95% CI 1.04-1.11, p < 0.001) and BMI ≥ 25 (adjusted OR 4.2, 95% CI 0.91-19.7, p = 0.033). Amongst all 275 diagnosed T2D patients, including those attending PHC clinics and those followed at the diabetes center, it was found that 40.1% followed dietary recommendations, 12% reported visiting a diabetes educator, 28.2% walked for exercise, and 13.5% attained recognized targets of HbA1c < 7%, blood pressure < 130/80 mmHg, and LDL cholesterol < 2.6 mmol/l. CONCLUSIONS: Almost half of the adult patients attending PHC clinics had undiagnosed T2D, or increased diabetes risk. Care practices, and achievement of treatment targets, were suboptimal.

    Full Text Available Abu Dhabi is in the process of urbanizing a group of Islands that surround its northern and eastern coastlines. Al-Lulu, Al-Saadiyat, Al- Maryah, Al-Reem and Yas Islands are all new urban enclaves that were desert islands and marshlands yet, have been developed over the past decade to urban islands that include epic and entertainment centres such as the Abu Dhabi Louvre, Guggenheim Museum, Ferrari World, NYU Abu Dhabi, the Paris Sorbonne Abu Dhabi in addition to iconic and exclusive waterfront residential units. These new islands re-brand the image of the main archipelago of Abu Dhabi that for decades retained a grid street pattern and pragmatic concrete blocks created in the late 1970s. The new urban islands transform Abu Dhabi’s image into a multinational modern Arab city seeking to become part of the global city network. Abu Dhabi’s new urban islands also act as breakwaters that protect the main archipelago’s coastline from erosion resulting from tidal change, because they are designed to include concrete and stone breakwater barriers. This paper represents a cross-disciplinary research between Civil Engineering and Architecture Departments in an attempt to explore the emerging infrastructure and urban expansion of Abu Dhabi from a multi-disciplinary perspective. We also highlight through simulating the effect of breakwaters on wave heights two scenarios for Al-Lulu Island the importance of these new barrier Islands on the urban expansion of Abu Dhabi.

  17. Crimes of obedience: "groupthink" at abu ghraib.

    Post, Jerrold M; Panis, Lara K

    2011-01-01

    Clear evidence of authorization at the highest levels belies administration statements to the effect that the torture at Abu Ghraib was an aberration and simply unauthorized actions by rogue soldiers. The administration reflected a "group mind," demonstrating many qualities of "groupthink." Whatever was necessary, including torture and violation of the Geneva accords, the system in effect authorized, because of the perceived danger to the system and the desperate requirement to get the information out of "them" by whatever means necessary, information that could save lives. The sanctioned violence demonstrated the qualities identified by Kelman and Hamilton (1989) in their study of the Mylai massacre as characteristic of sanctioned massacres: authorization, routinization, and dehumanization. It would seem that officials and participants exhibited all of these characteristics in the decision to conduct extreme interrogation on the "unlawful combatants" imprisoned at Abu Ghraib.

    2015-10-01

    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.

  3. Jebel Hafit and the Al Ain oases (Eastern Abu Dhabi, United Arab Emirates): an integrative approach of a cultural landscape through the scope of geodiversity

    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.

    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.

    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.

    Full Text Available Abstract: This study analyses the prisoner abuse at Abu Ghraib in the light of Islamic and International laws. Using documentary sources, the paper argues that Islamic law is far superior than the International law as enshrined in the Geneva Conventions and the United Nations Charter on the treatment of prisoners of war. It found the abuse of the prisoners at Abu Ghraib a routine operation carried out in obedience to orders issued by the higher authorities. The photographs portraying images of dehumanization in Abu Ghraib is unacceptable either in Islamic or international law.

    In the last few years Abu Simbel area received a special attention from the Egyptian government from the tourism point of view as well as the construction of new projects, cities and cultivation of more new areas. As this area is seismically active we decided to carry out studies on attenuation of high-frequency seismic waves at this area. The quality factor (Q) of P-wave was calculated using the Spectral ratio known as the Single-Station method. A selected data set of 14 shallow seismic events recorded by a local network operated around the area was used to calculate QP for four stations. Magnitude of these earthquakes varied between 1.7 and 3.6. The results show variations in QP as a function of frequency according to the power law Q = Q0fn, with frequency dependence coefficient n ranging between 0.4 and 1.2. Strong azimuthal variations of QP were found. It is proposed that this variation indicates presence of local strong lateral heterogeneities and/or fluid filled cracks.

    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

    The present investigation aimed to assess the possibility of using plasma levels of erythropoietin (EPO) hormone and tissue changes of hematopoietic organs as biomarkers of environmental pollution in abu mullet (Liza abu) and tiger tooth croaker (Otolithes ruber) collected from Musa Creek (northwest of the Persian Gulf). 120 L. abu and O. ruber were collected from five stations at the Musa Creek: Petrochemical, Ghanam, Doragh, Zangi and Patil stations. Blood samples were obtained from the caudal vein. Tissue samples were also taken from the spleen and head kidney, and tissue sections were prepared according to routine histological methods. The concentrations of Hg, Pb, Zn, Cu, and Cd were also measured in the sediment samples. The minimum level of EPO and the most severe tissue changes were determined in fish collected near a Petrochemical station. This station is adjacent to the Imam Khomeini Petrochemical Complex and receives highly contaminated effluents from this complex. The highest degree of contamination (Cd) also belonged to this station. The fish collected from the Patil station represented the highest EPO level and the least tissue changes. This station exhibited a lesser degree of contamination. Based on the results, there was a significant correlation between the plasma level of EPO hormone and the degree of environmental contamination.

    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.

    Two profiles have been sampled from the Nubia Sandstone at Aswan, south Western Desert: The 1st profile has been taken from Abu Aggag Formation and the 2nd one was from Sabaya Formation (23.25 oN, 32.75 oE). 136 oriented cores (from 9 sites) have been sampled. Abu Aggag Formation is of Late Cretaceous (Turonian) and Sabaya Formation is of Early Cretaceous (Albian-Cenomanian). The studied rocks are subjected to rock magnetic measurements as well as demagnetization treatment. It has been found that hematite is the main magnetic mineral in both formations. Four profile sections (normal polarity) from Abu Aggag Formation, yielded a magnetic component with D = 352.7°, I = 36.6° with 95 = 5.2° and the corresponding pole lies at lat. = 82.8 °N and long. = 283.1 °E. Five profile sections (normal polarity) from Sabaya Formation, yielded a magnetic component with D = 348.6°, I = 33.3° with 95 = 5.8° and the corresponding pole lies at lat. = 78.3 °N and long. = 280.4 °E. The obtained paleopole for the two formations lies at lat. = 80.5 °N and long. = 281.7 °E. The obtaind components are considered primary and the corresponding paleopole reflects the age of Nubia Sandstone when compared with the previously obtained Cretaceous poles for Egypt.

    Full Text Available ON THE GRAMMATICAL STATUS OF LITH. abu, LATV. abi, OPR. abbaiSummaryThe article deals with the grammatical status of Lith. abu ‘both’, Latv. abi and OPr. abbai. In the Baltic literature, these words are traditionally referred to as numerals. However, the said words and the numerals – Lith. du ‘two’, Latv. divi, OPr. dwai – have different lexical meanings. The presupposition of the utterances with Lith. du, Latv. divi, OPr. dwai and Lith. abu, Latv. abi, OPr. abbai does not lead to the assumption that Lith. abu, Latv. abi and OPr. abbai are numerals. Cf. Jonas atsivežė du sūnus (‘John has brought two sons’ and Jonas atsivežė abu sūnus (‘John has brought both sons’. The first utterance implies that John may have even more sons (but he has brought only two, whereas the second utterance indicates that John does not have more sons (and he has brought all of them. The meaning of Lith. abu, Latv. abi, OPr. abbai suggests that the latter words should be considered pronouns. Moreover, these words function as pronouns in the structure of the text, too; the Lith. numeral du, Latv. divi, OPr. dwai usually occur in the focus, whereas the Lith. pronoun abu, Latv. abi, OPr. abbai occur in anaphoric structures. The contextual partners of the Lith. pronoun abu and the Latv. pronoun abi are always nouns which mean ‘forming a pair’ or ‘having two sides’: ãkys (‘eyes’, rañkos (‘hands’, aũsys (‘ears’, etc., (Latv. acis, rokas, ausis; kẽlias (‘road’, gãtvė (‘street’, tãkas (‘path’, geležìnkelis (‘railway’, ežià (‘boundary’, ùpė (‘river’, griovỹs (‘ditch’, kanãlas (‘canal’, pýlimas (‘dyke’, síena (‘wallֹ’, etc., (Latv. ceļš, iela, taka, dzelzceļš, eža, upe, grāvis, kanāls, dambis, valnis, robeža, siena. Lith. abu, abi and the Latv. dialect forms obu, obi are reflections of the pronominal dual inherited from Proto-Indo-European.

    Abu Dabbab area is considered as one of the most active earthquake sources in Egypt. It is defined by its swarm type activity, and complicated stress pattern. This study was conducted to evaluate the two and three dimensional spatial distribution of b-value at Abu Dabbab area (Margin of the northern Red Sea Rift, Egypt). The gridding technique of Wiemer and Wyss (1997) was used to compute b-value using ZMAP software. The b-value is calculated from a catalog consisting of 850 well-located earthquakes, which were recorded from 1st June to August 2004, using the maximum likelihood method. These earthquakes were recorded by temporary digital seismic network, with magnitudes ranging from -1 to 3.4 ML. It is important to mention that the variations of b-value with time cannot be easily detected for a short period. Hence, this study has been carried out to examine the variations of b-value in space. The computed b-value in the Abu Dabbab area does not follow a uniform distribution. A small volume of anomalously high b-value (b > 1.8) exists in the central part of the area at a depth between 6 and 9 km. This seems to agree with the reported low velocity value derived from previous P-wave travel time tomography studies (Hosny et al., 2009) and the low Q value (Abdel-Fattah et al., 2008). The existence of an anomalously high b-value region may be attributed to the presence of a magma reservoir or dyke zone beneath the northern Red Sea Rift that causes an intensively heterogeneous fractured crust or unusually high pore pressure.

    Discovered in 1969, the Abu Gharadig (AG) Field was the first large hydrocarbon discovery in the Abu Gharadig Basin of the Western Desert of Egypt. Oil production began in 1973, with gas brought into production in 1975. The field produces mainly from upper Cretaceous clastic reservoirs. The AG Basin is an E-W trending intracratonic rift basin, about 330 km long and 50-75 km wide. It was initially formed as a large half graben basin during the Jurassic time in response to Tethyan rifting and continued to subside throughout the Cretaceous time. The half graben was subsequently inverted during the Late Cretaceous as part of the Syrian Arc deformation which affected northern Egypt. The Mid-Basin Arch, the AG Anticline, and the Mubarak High are three NE-SW oriented main inversion anticlines located within the AG Basin and are controlled by inversion of pre-existing Jurassic rift faults. The AG Anticline has an overall NE-SW orientation with a gentle plunge towards the NE and SW. It is locally bounded by two NE-SW-trending inverted faults on the southwest and northeast, accounting for the asymmetry of the anticline. Reverse offset of Cretaceous horizons is obvious at these inverted faults. Fault propagation folding is developed above the tips of the inverted faults at the Late Cretaceous Abu Roash and Khoman Formations. Based on thickness changes and stratigraphic relationships, inversion started during the Santonian time and continued into the Campanian-Maastrichtian. Inversion continued during deposition of the Paleocene-Middle Eocene Apollonia Formation and the Late Eocene-Oligocene Dabaa Formation.

    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.

    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 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

    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.

    From the seismic tomography study, the 3D Vp and Vp/Vs crustal models indicate high Vp/Vs values forms an elongated anomaly, in the central part of the study area, that extends from a depth of 12 km to about 1–2 km of depth is obtained. By using this crustal model in relocations all seismicity informed that most of the seismicity strongly tend to occur in a cluster manner exactly above the southern part of the study area. Based on the conducted source mechanism study, it is noticed that shallow earthquakes are associated by a high CLVD ratio (up to 40%. Furthermore, initiation of a high level seismic activity, without a large seismic main shock is observed in the Abu-Dabbab area. The distribution of micro-earthquakes tends to align in an ENE–WSW direction marking a zone of activity verse the Red Sea. The nucleation of the seismic activity beneath the southern part of the Abu-Dabbab crust is more consistent with the obtained crustal deformation result by increasing the crustal movement in the south part than the northern part. Then, based on the obtained results of the above mentioned studies; seismic tomography; source mechanisms, and crustal deformation we conclude that these seismic activities that are associated by crustal deformation are owing to some magma activity beneath the crust of the Abu-Dabbab area.

    Populations of Holothuria scabra at Abu Rhamada Island were investigated during 52 months, from July 1999 to October 2003. During the first 23 months (July, 1999-May, 2001) the Island had a robust population with a tri-modal size frequency distribution curve, very high densities (85.7-95.1 ind./100 m2 at the sandy habitat), high abundance (3362-3110 individuals) and biomass (46.7-34.3 kg/100 m2). Also, during this period most individuals were at depths between 4 and 6m and no individuals were recorded deeper than 15m. The population declined after harvesting began (June, 2001) and by March, 2002 the size frequency distribution showed a bimodal pattern with an obvious decrease in abundance of large individuals. There was also a slight reduction in densities (73.2-60.1 ind./100 m2 at the sandy habitat), abundance (2292-1682 individuals) and biomass (21.6-11.3 kg/100 m2), and a marked shift towards deeper waters. Overfishing reached its maximum during the final 19 months of the study, and by October, 2003, density (30.7-0.4 ind./100 m2 at the sandy habitat), abundance (802-10 individuals) and biomass (6.9-0.1 kg/100 m2) were all greatly reduced. The size frequency distribution of the population became unimodal, large animals disappeared and no recruits were seen. During this period, individuals were found at very deep depths (30 to >40 m). The study also showed that sandy substrate was the preferred habitat for H. scabra, accommodating the largest number of individuals. The population of H. scabra at Abu Rhamada Island was found to spawn biannually from 1999 to 2001, then only once during 2002 when high fishing pressure occurred, and ceased completely in 2003. The sex ratio was not significantly different from 1:1 before fishing begun, but shifted to an increasing male bias reaching 93% males by January 2003. None of the small animals remaining after January, 2003 could be sexed. Size at sexual maturity decreased from prefishing (185 mm for females and 160 mm for

    Full Text Available Proses produksi biodiesel secara konvensional menggunakan bahan baku yang terbatas jumlahnya, proses yang rumit, dan banyaknya limbah yang dihasilkan menyebabkan produksi biodiesel dalam skala besar tidak dapat direalisasikan dengan mudah. Mikroalga merupakan sumber bahan alam terbarukan yang sangat potensial untuk produksi biodiesel karena kandungan minyaknya yang tinggi, kecepatannya tumbuh pada lahan yang terbatas, serta merupakan produk non-pangan. Salah satu jenis mikroalga dengan kandungan minyak yang relatif besar (28-32% berat kering adalah mikroalga Chlorella sp. Selain bahan baku, pemilihan proses yang lebih sederhana dan ekonomis perlu dikembangkan. Selama ini, proses produksi biodiesel konvensioanal banyak menghasilkan air limbah pada tahap pemisahan produk dari katalis yang larut dan produk samping yang dihasilkan. Oleh karena itu, untuk mengurangi limbah yang dihasilkan selama proses pemisahan tersebut, jenis katalis heterogen dapat digunakan untuk menggantikan katalis homogen alkali yang biasa digunakan. Katalis padat tersebut dapat disintesis dari abu vulkanik yang mengandung unsur-unsur seperti SiO2, Al2O3, Fe2O3, TiO2, MnO, CaO, MgO, Na2O, K2O, P2O5, serta beberapa elemen minor seperti Zr, Sr, dan V. Penelitian ini bertujuan untuk mengkaji jenis katalis dan aktivitasnya dalam reaksi transesterifikasi minyak mikroalga Chlorella sp menjadi biodiesel. Tahap awal penelitian yang dilakukan adalah preparasi minyak mikroalga yang akan digunakan untuk uji aktivitas katalis. Minyak mikroalga diperoleh dengan ekstraksi menggunakan metode maserasi menggunakan pelarut n-heksana. Rendemen minyak yang diperoleh sebesar 12,26%. Dari hasil uji GC-MS diketahui dua kandungan asam lemak terbesar dalam minyak mikroalga, yaitu Dodecanoic acid sebesar 59.52% dan n-Decanoic acid sebesar 12.64%. Selanjutnya minyak mikroalga direaksikan dengan metanol dengan rasio molar 1:6 menggunakan jenis katalis yang disintesis dari abu vulkanik. Preparasi katalis

    Earthquake hazard assessments are an important task for the design of earthquake resistant structures and insurance industry. Such assessments get more importance when the site of interest is located near an active earthquake zone. Such situation is present for the location of Abu Zenima city. The city is characterized by the presence of industrial and Maritime platform in addition to other Oil production facilities. These industrial facilities motivated the present work. The simulated earthquake ground motion time histories are conducted using stochastic technique. The magnitude used for simulation is obtained using both probabilistic and deterministic approaches. An analysis using both approaches shows that moderate earthquakes in the vicinity of the site could have the largest effects on the area. Thus an earthquake of magnitude 4.5 at a distance of 21 km is chosen as design earthquake. The simulated ground motions are presented in terms of acceleration, velocity, and displacement time histories. In addition the response spectra are also presented that may be used for engineering purposes.

    A direct current (dc) resistivity geoelectric technique is applied in the Abu Zenima area, West Sinai, Egypt to delineate salt water intrusion from the Gulf of Suez and evaluate the quality and some of the petrophysical parameters of the aquifer. Sixteen Schlumberger vertical electrical soundings (VES) with maximum AB/2 = 3000 m are conducted. The interpretation of the one-dimensional (1D) inversion of the acquired resistivity data could map the fresh to slightly brackish aquifer (true resistivity = 52-71 Ω m, thickness = 17-66 m), which floats on denser, more saline, deeper water (<5 Ω m). A number of water samples of the fresh aquifer are analysed to determine the total dissolved solids (TDS) concentrations (ppm). A good agreement is observed between the resistivity boundaries and the borehole data. The mutual relations between the aquifer layering, the direction of the groundwater flow and the hydrogeophysical conditions of the aquifer are investigated. The geoelectric (Dar-Zarrouk) parameters are determined and interpreted in terms of the hydraulic conductivity, transimissivity, clay content, grain size distribution and potentiality of the aquifer. The integration of the results indicates a high potentiality and a relatively good quality of the fresh to slightly brackish aquifer in the north-eastern part of the study area.

    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.

    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?

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

    Full Text Available The hydrography, nutrient levels and plankton abundance were investigated monthly for a complete annual cycle in the southwestern part of Abu Qir Bay, the most polluted and biologically productive area on the Egyptian Mediterranean coast. Intense temporal and spatial variability was observed in all measured parameters characteristic of the effects of several effluents discharged into the bay. Based on the present investigation, the southwestern Bay can be divided ecologically and biologically into two parts: one including the near shore strip, which is directly affected by the waste waters, and a second comprising the southwestern part of the coastal strip and the offshore stations, both of which are relatively far away from the land-based effluents. The Bay water was characterized by low transparency (monthly average: 64-280 cm, dissolved oxygen (monthly average 2.0-6.8 mg/l and surface salinity (monthly average: 24.8-37.9 ppt, the highest limits usually being in the offshore section. Water fertility and plankton production were high in the Bay indicating an occasionally acute degree of eutrophication, particularly nearshore. Great variations occurred in the concentrations of nutrients throughout the year, with monthly averages of 0.8-50.88 mM for ammonia, 0.42-3.28 mM for nitrite, 1.29-17.36 mM for nitrate, 0.32-3.61 mM for reactive phosphate and 1.09-33.34 mM for reactive silicate. Similarly, the abundance of both phytoplankton and zooplankton showed pronounced temporal and spatial variability, whereas the monthly average chlorophyll-a fluctuated between 2.06 and 52.64 mg/l and zooplankton between 31x103 and 248.6x103 ind./m3. However, the absolute values of all parameters indicated remarkably wider ranges of variations. Significant correlation was found between chlorophyll-a and some ecological parameters like temperature, salinity, transparency, dissolved oxygen, nitrite and between zooplankton and temperature, while there was a significant

    Full Text Available Introduction: The area around Wadi Abu Zawal is occupied by gneisses-migmatites, island arcs metavolcanics, Dokhan volcanics, Hammamat sediments, intrusive rocks of granitic and gabbroic composition and dyke swarms.Materials and Methods: The present work concerning on the geology, geochemistry and petrogenesis of the MME and the host granitoid rocks of that area. The analytical methods for major and trace elements of some representative samples were carried out by XRF technique at the Institute of BGR in Hannover, Germany.Results: Mineralogically, MME are composed mainly of plagioclase, hornblende, biotite and quartz with accessory of sphene, acicular apatite and opaque oxides, while chlorite and epidote are secondary ones. Whereas Abu Zawal granitoid rocks are subsolvus and consist of variable contents of plagioclase, K-feldspar, quartz, and biotite, with accessory sphene, zircon and opaque oxides, typical of I-type granites. The studied Abu Zawal area represents part of the northeastern Egypt which formed by regional crustal extension and magmatic-arc regimes during Pan-African orogenic event.The MME display major, trace element contents and tectonic setting comparable with the end members of (GDT and (IAG of the Eastern Desert which produced (by fractionation from a mantle-derived tholeiitic magma in an island-arc tectonic environment. Abu Zawal granitoid rocks exhibit trace element characteristics of volcanic-arc granites, and formed in an Andean-type setting.Conclusions: On the variation diagrams, major and trace element contents of the MME and granitoid rocks display conspicuous gap and two distinct trends one for the MME, (IAG and the other for the Abu Zawal granitoid rocks, which indicates that they are not genetically related and suggest the crustal source for the host granitoid rock.

    Abu Dabbab seismogenic source region is of unique seismic activity located on the Egyptian Red Sea coast. It's known as earthquake Cannons where the earthquakes are accompanied by a sound of distinct rumbling similar to the sound of a distant quarry blast which is heard by humans for several generations. Seismic activity of Abu Dabbab becomes very well determined after establishing of the Egyptian National Seismic Network 1997. Joint earthquake tomography inversion of local and regional data has been performed in order to image the crustal heterogeneity and the origin of the cannons earthquakes. Most previous studies suggested that this activity is of magmatic origin. We found the seismicity forms an arc shaped cluster that surrounds an aseismic block. This aseismic block has high velocities and a low Vp/Vs ratio. The origin of this seismic activity is probably due an active fault below the non-deformed block of Precambrian Igneous rock reaching a depth of ~10 km. Spatial mapping of the frequency magnitude distribution of the earthquakes and 3D-b-value indicate a strong variation moreover high b-value (1.4) at depth downward the rigid block. The Combined interpretation of the seismic imaging and 3D b-value in addition to the seismological and the geophysical observations revealed the tectonic origin of the earthquake activity in this area which is related strongly to the evolution of the crust in the Red Sea and its tectonic activity.

  12. The meaning of education after Abu Ghraib: revisiting Adorno’s politics of education O que pode significar a educação após Abu Ghraib: revisitando a política de educação de Adorno

    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

    Full Text Available The studied mineralized lamprophyre dyke in Abu Rusheid area is trending NNW-SSE, and occurs withinAbu Rusheid mineralized shear zone, measuring 0.2 - 1.0 m in width and 0.5 - 1.0 km in length. It was emplacedparallel with the Abu Rusheid shear zone. The dyke is mainly composed of plagioclases, amphiboles, mica (musco-vite and biotite, relics of pyroxenes with K-feldspars and quartz derived from surrounding country rocks asphenocrysts embedded in fine-grained groundmass. The lamprophyre dyke hosts REE-minerals monazite-(Nd,xenotime-(Y, and REE-bearing minerals apatite, fluorite, zircon-(Hf, rutile with inclusions of xenotime and ironoxides. The emplacement of lamprophyre dyke caused heating in the mineralized shear zone of Abu Rusheid area.The lamprophyre dyke was subsequently affected by hydrothermal alterations (e.g. chlorite-carbonate, muscovitization,fluoritization.The REE were remobilized from the mineralized shear zones by hydrothermal solutionsand re-precipitatedas REE-minerals xenotime-(Y and monazite-(Nd around flourapatite, fluorite, zircon andrutile. The solid solutions between monazite-(Nd and xenotime-(Y were formed as a product precipitation fromhydrothermal solutions. Also, the apatite mineral in the lamprophyre dyke was subjected to the heating duringthe emplacement, which lead to its alteration and breakdown with concominant precipitation of xenotime-(Yand monazite-(Nd. The chemistry of monazite-(Nd and xenotime-(Y obtained by scanning electron microscopy(SEM, and electron probe microanalysis (EPMA, showed that these minerals are enriched in U and Th. Themonazite-(Nd associated with fluorapatite in the studied dyke is poor in Th (0.02 ≤ Th ≤ 0.81 wt%, but usuallyrich in U (0.92 ≤ U ≤ 2.91 wt%, which indicates that monazite formed as a result of flourapatite metasomatism.

    The authors draw upon the experiences of one of the co-authors as an expert witness in sociology for mitigation at three of the courts-martial pertaining to the abuse at Abu Ghraib that were held at Ft. Hood, Texas in the year 2005 (for Javal Davis, Sabrina Harman, and Lynndie England). In addition, this paper is based upon the thousands of pages of affidavits, testimony, and U.S. Government reports concerning Abu Ghraib. These internal government reports, as well as the Levin-McCain report, point to collective responsibility and the responsibility of individuals high in the chain of command for establishing unlawful techniques. We review the shortcomings of a purely psychological approach for understanding the abuse, and turn to Durkheim's original understanding of anomie as a state of social derangement or rule by lack of rule to introduce the ideas of the social origins of and social responsibility for the abuse. We conclude with sociological suggestions for reforming some of the legal, medical, psychiatric, and other professional complicity in the abuse at Abu Ghraib.

    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

    Sufyan Sub-basin is an East-West trending Sub-basin located in the northwestern part of the Muglad Basin (Sudan), in the eastern extension of the West and Central Africa Rift System (WCARS). The Early Cretaceous Abu Gabra Formation considered as the main source rock in the Muglad Basin. In Sufyan Sub-basin the Early Cretaceous Upper Abu Gabra Formation is the main oil-producing reservoir. It is dominated by sandstone and shales deposited in fluvio-deltaic and lacustrine environment during the first rift cycle in the basin. Depositional and post-depositional processes highly influenced the reservoir quality and architecture. This study investigates different scales of reservoir heterogeneities from macro to micro scale. Subsurface facies analysis was analyzed based on the description of six conventional cores from two wells. Approaches include well log analysis, thin sections and scanning electron microscope (SEM) investigations, grain-size, and X-ray diffraction (XRD) analysis of the Abu Gabra sandstone. The cores and well logs analyses revealed six lithofacies representing fluvio-deltaic and lacustrine depositional environment. The sandstone is medium to coarse-grained, poorly to moderately sorted and sub-angular to subrounded, Sub-feldspathic arenite to quartz arenite. On macro-scale, reservoir quality varies within Abu Gabra reservoir where it shows progressive coarsening upward tendencies with different degrees of connectivity. The upper part of the reservoir showed well connected and amalgamated sandstone bodies, the middle to lower parts, however, have moderate to low sandstone bodies' connectivity and amalgamation. On micro-scale, sandstone reservoir quality is directly affected by textures and diagenesis.The XRD and SEM analyses show that kaolinite and chlorite clay are the common clay minerals in the studied samples. Clay matrix and quartz overgrowth have significantly reduced the reservoir porosity and permeability, while the dissolution of feldspars

    Full Text Available The era of the early ‘Abbasid caliphate made an important mark on the history of the world by the event of the Greek translation movement, i.e. the translation of Greek thoughts into the Arabic language. In addition to this development, the era also saw the flourishing of interreligious discourse, in both polemical literatures and religious debates, especially between Christians and Muslims. This article tries to describe how those two historical remarks are correlated under the light of other factors such as politics and religious identity. The earliest debate was happened between caliph al-Mahdi (r. 755-785 CE and a Nestorian Catholicos, Timothy I (728- 823 CE, as the first sample of religious discourses. The second one is the debate between the caliph al-Ma’mun (r. 813-833CE, who arranged many religious debates in his court, with Theodore Abu Qurra (755 – 830 CE, Bishop of Harran. By knowing the motives of the two caliphs who sponsored those events, readers would catch a better picture of the historical contexts of that time.

    Hierakonpolis, Greek for City of the Hawk, nearly 25 km NW of Idfu (Egypt), is an important and extensive archaeological discovery covering a large area. Its richness in archaeological artifacts makes it a valuable site. It has a valid claim to be the first nation state, as indicated by the Palette of Narmer discovered in its main mound. Geological and hydrogeological investigations at the Hierakonpolis Temple Town site documented nearly a 4.0-m water table rise from as early as 1892 to the present. In addition to the rising water levels, the increase of both subsoil water salinity and humidity threatens and damages fragile carvings and paintings within tombs in Kingdom Hill, the foundation stability of the site, and the known and still to be discovered artifact that recent pottery finds dates at least 4,000 BCE. Representative rock and soil samples obtained from drilled cores in the study area were chosen for conducting detailed grain size and X-ray analysis, light and heavy mineral occurrences, distribution of moisture and total organic matter, and scanning electron microscopy investigations. Mineralogical analysis of clays indicated that the soil samples are composed of smectite/illite mixed layers with varying proportions of smectite to illite. Kaolinite is the second dominant clay constituent, besides occasional chlorite. Swelling of the clay portion of the soil, due to the presence of capillary groundwater, in contact with buried mudbrick walls expands and causes severe damage to important exposed and buried mudbrick structures, including the massive ancient "fort" believed to date from the Second Dynasty (from 2,890 to 2,686 BC). The "fort" is 1.0 km south of the Temple Town mounds near to confluence of Wadi Abu Sufian. Groundwater samples from the shallow aquifer close by the intersection of Wadi Abu Sufian and the Nile flood plain were analyzed for chemical composition and stable isotope ratios. The groundwater in the upper zone (subsoil water) within fine

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

    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.

    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.

    This survey reviews similar contents of the two Divan using comparative aspect in Abu al-Tayyib and Masu’d Sa’d-i Salman’s poems. Several exemplifications show that Masu’d Sa’d-i Salman sometimes translated al-mutanbbi’s poets and used them artily. Sometimes however, we can find identical contents originating from connotation between the two poets, so they should not be considered as adoption or translation.

    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.

    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.

  10. Petrogenesis of cogenetic silica-oversaturated and -undersaturated syenites of Abu Khruq ring complex, South Eastern Desert, Egypt

    The upper Cretaceous Abu Khruq ring complex (ARC) is located in the South Eastern Desert of Egypt displays concentric zonation of syenitic rocks from quartz-rich syenite at the margin, through alkali feldspar syenite to nepheline syenite in the centre. The syenitic rocks occur with nepheline monzogabbro, volcanic rocks (phonolite and trachyte) and the quartz- and nepheline-bearing pegmatites. Rocks of contrasting composition (mafic and salic) exhibit sophisticate geometric relationships. The nepheline monzogabbroic rocks have pillowy xenoliths forms within the salic (nepheline syenite and quartz alkali feldspar syenite) rocks, suggesting synchronous emplacement of the mafic and salic magmas. Clinopyroxene analysis of mafic and salic plutonic rocks of the ARC revealed that the overall pyroxene trend suggesting that fractionation involved a late, progressive increase in Na, in a reaction of the type Ca Mg Fe2+↔Na Fe3+. The chemistry of the analysed amphiboles are compositionally similar to those from typical differentiated peralkaline suites. Geochemically, the complex is enriched in the LILE, HFSE and REE. The concentrations of the compatible elements (V, Sr and Ba) generally decrease with increasing silica, consistent with fractional crystallization. A generalised increase in the Nb/Ta from the nepheline monzogabbro to nepheline syenite compositions is attributed to titanite fractionation. All the rock samples show relative increment of the LREE content than the HREE indicating weak to steep fractionated REE patterns (La/Yb) from 9.43 to 10.86, and thus retaining the geochemical characteristics of anorogenic suites. The magma sources of ARC are not derived from normal primitive mantle. The early stages of differentiation involved extensive olivine and pyroxene fractionation, the fractionation of amphibole, titanite, magnetite, apatite and feldspar may have been involved in the genesis of the salic differentiated compositions. The deviation towards silica

    Potential field data of the area east of Abu Gharadig basin were used to delineate the tectonic framework of probable economic interest and for future development plans for the area. To achieve this goal, the RTP and Bouguer gravity maps of the study area were subjected to several filtering and processing techniques. The regional magnetic map shows NE-SW high regional magnetic trends at the northwestern and southeastern parts as well as low magnetic trends at the central part reflecting thick non-magnetized sediments and/or deep highly magnetized basement rocks. Similarly, the regional gravity map shows NE-SW diagonal high and low gravity trends across the entire area of study as well as a distinct increase of gravity values toward the northwest corner reflecting thickening of sedimentary cover and/or deepening of denser basement rock at the central part. The residual maps reveal many anomalies of shallow sources with different polarities, amplitudes and extensions in the form of alternating high and low gravity and magnetic indicating that the basement rocks are dissected by faults forming uplifted and downthrown blocks. Edge detection techniques outlined effectively the boarders and extensions of the structural highs and lows through showing gravity and magnetic maxima over the edges of these tectonic features. Moreover, the River Nile course is controlled by shallow normal faults affecting the recent Nile sediments and is clearly shown by edge detection maps of gravity data. Euler deconvolution of magnetic and gravity data reveals clustering of solution along fault trends or causative bodies centers. The Euler depth estimate to the basement surface shows a good correlation with the depth determined by the power spectrum method where its value ranges around 4 km. The interpreted basement tectonic map of the study area is dominated by ENE-WSW Syrian Arc, NW-SE Gulf of Suez and Red Sea, NE-SW Aqaba, E-W Mediterranean and N-S East Africa tectonic trends.

  13. 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

    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.

    2015-06-01

    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.

    Full Text Available Using solid state nuclear track detectors and employing CR-39 cylindrical technique, the depth of the subsurface uranium deposits were determined. This techniques depends mainly on the nuclear track detector situated in zigzag form inside a polyethylene cylinder of 65 cm length and 7 cm diameter. This technique was applied on a borehole in a granite mass Abu Rushied area, southeast area desert. The obtained results revealed that, the depth of U -ore deposited reached about 89 m with thickness nearly 24 m. The obtained data for radon concentrations were also used for the determination of the exhalation rates, the measured values for exhalation rate (mBqm−2h−1 varies between 6.14E-03 at h = 50 cm and 4.53E-02 at h = 10 cm, The obtained values are comparable with that recorded for the granite type of rock.

    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.

  20. 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.

    This paper describes the Neogene lava-sediment mingling from the Abu Treifiya Basin, Cairo-Suez district, Egypt. The lava-sediment interactions as peperites have been identified for the first time at the study area and can be used as paleoenvironmental indicators. The identification of peperite reflects contemporaneous time relationship between volcanism and sedimentation and this finding is of primary importance to address the evolutional reconstruction of the Abu Treifiya Basin. Characterization of the facies architecture and textural framework of peperites was carried out through detailed description and interpretation of their outcrops. The peperites and sedimentary rocks are up to 350 m thick and form a distinct stratigraphic framework of diverse lithology that is widespread over several kilometers at the study area. Lateral and vertical facies of the peperites vary from sediment intercalated with the extrusive/intrusive basaltic rocks forming peperitic breccias to lava-sediment contacts at a large to small scales, respectively. Peperites encompass five main facies types ascribed to: (i) carbonate sediments-hosted fluidal and blocky peperites, (ii) lava flow-hosted blocky peperites, (iii) volcaniclastics-hosted fluidal and blocky peperites, (iv) sandstone/siltstone rocks-hosted blocky peperites, and (iv) debris-flows-hosted blocky peperites. Soft sediment deformation structures, vesiculated sediments, sediments filled-vesicles, and fractures in lava flows indicate that lava flows mingled with unconsolidated wet sediments. All the peperites in this study could be described as blocky or fluidal, but mixtures of different clast shapes occur regardless of the host sediment. The presence of fluidal and blocky juvenile clasts elucidates different eruptive styles, reflecting a ductile and brittle fragmentation. The gradual variation from fluidal to blocky peperite texture, producing the vertical grading is affected by influencing factors, e.g., the viscosity, magma

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

    Directory of Open Access Journals (Sweden)

    Teja, Ramón

    2011-12-01

    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.

    Sharp, I.R.; Gawthorpe, R.L.; Corfield, S.; Carr, I.

    1999-07-01

    This presentation describes facies and stratal stacking patterns that developed within the ''rift-initiation'' Oligo-Miocene Abu Zenima and Nukhul Formations of the Suez Rift during normal fault propagation and linkage. This formation comprises fluvial red bed conglomerates, sandstones, and lacustrine marls deposited in early-formed structural depressions. Initial comparisons with the Tilje, Ror, Tofte and Ile Formations of the Halten Terrace of Mid Norway reveal some marked similarities. Deposition is concentrated in elongate marine embayments parallel to the main structural elements resulting in axial palaeocurrents with a dominant tidal signature. Point-sourced fan deltas are also evident, sediment dispersal being strongly influenced by fault-controlled basin physiography. Marked strike variation in the age of syn-rift wedges adjacent to block bounding faults are also evident, a pattern consistent with lateral fault growth. These data indicate that to produce accurate reconstructions of synrift phases of basin development one must address the dynamics of structural-stratigraphic interactions, in particular recognition of the nature of propagation and linkage of originally isolated normal faults. Furthermore, a pragmatic approach to applying sequence stratigraphic methodology during active phases of basin growth is crucial to successful correlation.

    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.

    Mohamed, M. M.

    2014-09-01

    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.

    2015-04-01

    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.

    2003-06-01

    The Holocene sediments of the coast of the United Arab Emirates in the southeastern Arabian Gulf are frequently cited in the literature as type examples for analogous assemblages of carbonates, evaporites and siliciclastics throughout the geologic record. This paper is intended as a convenient single source for the description of sediments of this region, providing information on how to reach the classic localities and some of the analogs. The Holocene sediments of the region accumulate over an area that is 500 km long and up to 60 km wide. The sediments collecting offshore are predominantly pelecypod sands mixed with lime and argillaceous mud, with these latter fine sediments increasing as the water deepens. The pelecypod-rich sediments also collect east of Abu Dhabi Island both in the deeper tidal channels between the barrier island lagoons and in deeper portions of the protected lagoons. West of Abu Dhabi Island the shallow water margin is the site of coral reefs and coralgal sands, whereas to the east oolites accumulate on the tidal deltas of channels located between barrier islands. Grapestones accumulate to the lee of the reefs and the oolite shoals where cementation becomes more common. They are particularly common on the less protected shallow water margins of the lagoons west of Abu Dhabi Island. Pelleted lime muds accumulate in the lagoons in the lee of the barrier islands of the eastern Abu Dhabi. Lining the inner shores of the protected lagoons of Abu Dhabi and on other islands to the west are cyano-bacterial mats and mangrove swamps. Landward of these, a prograding north facing shoreline is formed by supratidal salt flats (sabkhas), in which evaporite minerals are accumulating. This paper describes the localities associated with (1) the mangrove swamps of the west side of the Al Dhabaiya peninsula; (2) the indurated cemented carbonate crusts, cyanobacterial flats and sabkha evaporites on the shore of the Khor al Bazam south of Qanatir Island; (3) the

    Bariatric surgery patients are at high risk for venous thromboembolism (VTE), and chemoprophylaxis is recommended. Sheikh Khalifa Medical City (SKMC) is an American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) member since 2009. We report the rates of VTE in bariatric surgery patients from 2010 to 2016 compared to ACS NSQIP bariatric surgery programs before and after switching from heparin to low molecular weight heparin (LMWH), initiating mandatory risk assessment using Caprini scoring for VTE and adopting an aggressive strategy for high-risk patients regarding dosage of LMWH and chemoprophylaxis after discharge. During the study period, there were 1152 cases (laparoscopic Roux-en-Y gastric bypass (LRYGB) 625 and laparoscopic sleeve gastrectomy (LSG) 527) at Bariatric & Metabolic Institute (BMI) Abu Dhabi compared to 65,693 cases (LRYGB 32,130 and LSG 33,563) at ACS NSQIP bariatric surgery programs. VTE rates remained stable at ACS NSQIP bariatric surgery programs from 2010 to 2016 (0.45, 0.45, 0.45, 0.25, 0.35, 0.3, and 0.3%). In contrast, VTE rates at BMI Abu Dhabi decreased from 2.2% in 2011 to 0.35% after we adopted an aggressive strategy to VTE without an increase in bleeding complications. LRYGB patients with VTE had higher OR time, leak, collection, and mortality at ACS NSQIP hospitals compared to those at BMI Abu Dhabi. In contrast, rates were similar in LSG patients with VTE. Changing our approach to VTE management led our VTE rates to decrease and become like those of ACS NSQIP bariatric surgery patients in LSG and LRYGB.

    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.

    A molten salt direct absorption receiver, CSPonD, used to simultaneously collect and store thermal energy is being tested by Masdar Institute and MIT in Abu Dhabi, UAE. Whilst a research-scale prototype has been combined with a beam-down tower in Abu Dhabi, the original design coupled the receiver with a hillside heliostat field. With respect to a conventional power-tower setup, a hillside solar field presents the advantages of eliminating tower costs, heat tracing equipment, and high-pressure pumps. This analysis considers the industrial viability of the CSPonD concept by modeling a 10 MWe up-scaled version of a molten salt direct absorption receiver combined with a hillside heliostat field. Five different slope angles are initially simulated to determine the optimum choice using a combination of lowest LCOE and highest IRR, and sensitivity analyses are carried out based on thermal energy storage duration, power output, and feed-in tariff price. Finally, multi-objective optimization is undertaken to determine a Pareto front representing optimum cases. The study indicates that a 40° slope and a combination of 14 h thermal energy storage with a 40-50 MWe power output provide the best techno-economic results. By selecting one simulated result and using a feed-in tariff of 0.25 /kWh, a competitive IRR of 15.01 % can be achieved.

    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

    The OPEC countries being arranged in business participation status in the infrastructure, particularly its recent trend, the main countries among them were analyzed in oil policy. As the oil price depends considerably upon the oil situation, the oil producing countries can secure a stabilized income by amplifying the exportation of oil products, small in price change and high in additional value. Having early started an uninterrupted direct participation in the infrastructure of oil consuming countries, Kuwait was securing a comparatively stabilized income therefrom. Among the OPEC countries participating in the infrastructure, Venezuela is at the head in number and refining capacity of refineries owned overseas. Later than Kuwait and Venezuela, Saudi Arabia started a participation in the infrastructure with a venturing foundation jointly with Texaco in 1988. Though proceeding with a participation in the infrastructure almost concurrently with Saudi Arabia, Abu Dhabi was almost limited to capital investments in the worldwide major oil companies. 6 refs., 22 tabs.

    There is growing awareness of the importance of mental health issues in the perinatal period in Western societies, but very little information is available from Muslim and Arab countries. Qualitative information gathered using focus group discussions of women of childbearing age is presented along with additional information obtained from key informant interviews with grandmothers, husbands, and health care professionals in the United Arab Emirates. The participants were women attending a public sector clinic in Al Ain, Abu Dhabi, and a private clinic in Dubai on a particular day. There were 19 women in the age range 17 to 46 years (M age = 29 yr.). The majority of the women who took part in the study did not recognize postnatal depression as a psychological issue but considered the problems a result of "evil eye" or "Jinn." The present findings suggest the need for initiating awareness programs among women and training of health professionals on the detection and management of postnatal depression.

    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.

    This study covers five fog events reported in 2014 at Abu Dhabi International Airport in the United Arab Emirates (UAE). We assess the performance of WRF-ARW model during fog conditions and we intercompare seven different PBL schemes and assess their impact on the performance of the simulations. Seven PBL schemes, namely, Yonsei University (YSU), Mellor-Yamada-Janjic (MYJ), Moller-Yamada Nakanishi and Niino (MYNN) level 2.5, Quasi-Normal Scale Elimination (QNSE-EDMF), Asymmetric Convective Model (ACM2), Grenier-Bretherton-McCaa (GBM) and MYNN level 3 were tested. Radiosonde data from the Abu Dhabi International Airport and surface measurements of relative humidity (RH), dew point temperature, wind speed, and temperature profiles were used to assess the performance of the model. All PBL schemes showed comparable skills with relatively higher performance with the QNSE scheme. The average RH Root Mean Square Error (RMSE) and BIAS for all PBLs were 15.75 % and -9.07 %, respectively, whereas the obtained RMSE and BIAS when QNSE was used were 14.65 % and -6.3 % respectively. Comparable skills were obtained for the rest of the variables. Local PBL schemes showed better performance than non-local schemes. Discrepancies between simulated and observed values were higher at the surface level compared to high altitude values. The sensitivity to lead time showed that best simulation performances were obtained when the lead time varies between 12 and 18 hours. In addition, the results of the simulations show that better performance is obtained when the starting condition is dry.

    In this study, we intercompare seven different PBL schemes in WRF in the United Arab Emirates (UAE) and we assess their impact on the performance of the simulations. The study covered five fog events reported in 2014 at Abu Dhabi International Airport. The analysis of Synoptic conditions indicated that during all examined events, the UAE was under a high geopotential pressure and light wind that does not exceed 7 m/s at 850 hPa ( 1.5 km). Seven PBL schemes, namely, Yonsei University (YSU), Mellor-Yamada-Janjic (MYJ), Moller-Yamada Nakanishi and Niino (MYNN) level 2.5, Quasi-Normal Scale Elimination (QNSE-EDMF), Asymmetric Convective Model (ACM2), Grenier-Bretherton-McCaa (GBM) and MYNN level 3 were tested. In situ observations used in the model's assessment included radiosonde data from the Abu Dhabi International Airport and surface measurements of relative humidity (RH), dew point temperature, wind speed, and temperature profiles. Overall, all the tested PBL schemes showed comparable skills with relatively higher performance with the QNSE scheme. The average RH Root Mean Square Error (RMSE) and BIAS for all PBLs were 15.75% and - 9.07%, respectively, whereas the obtained RMSE and BIAS when QNSE was used were 14.65% and - 6.3% respectively. Comparable skills were obtained for the rest of the variables. Local PBL schemes showed better performance than non-local schemes. Discrepancies between simulated and observed values were higher at the surface level compared to high altitude values. The sensitivity to lead time showed that best simulation performances were obtained when the lead time varies between 12 and 18 h. In addition, the results of the simulations show that better performance is obtained when the starting condition is dry.

    Full Text Available The objective of this study was to measure the effect of different levels of shrimp head waste (SHW substituting fish meal (FM in broiler diets. FM is the sole crude protein from animal sources. A control fish meal broiler diet and four different levels of SHW substituted for crude protein FM were fed to CP 707 Arbor Acres broiler strains from day old chick to four weeks of age. The crude proteins FM were replaced with 0 (R0; 25 (R1; 50 (R2; 75 (R3; and 100 (R4 percent of crude protein SHW. The five treatments were assigned to completely randomized design. 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.

    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.

    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.

    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.

    Al-Samaliah Island is one of the inshore islands of U.A.E. located at about 12 km north-east of Abu Dhabi in the Arabian Gulf. It has a flat undulating surface with neither sand dunes nor rocky hills. Its sandy soil is generally salt-affected with variable percentages of salts. The vegetation of Al-Samaliah Island is essentially halophytic and may be categorized as: seagrasses, mangal and littoral saltmarsh types. The main species include: Cymodocea ciliata, Halophila spp. and Halodula univervis (seagrasses), some algae, Avicennia marina (mangrove), Arthrocnemum macrostachyum, Seidlitzia rosmarinus, and Suaeda vermiculata (salt marsh). Other halophytes commonly present are: Anabasis setifera, Halocnemum strobilaeum, Halopeplis perfoliata, Salsola imbricata and Zygophyllum gatarense in addition to two annuals: Schangenia aegyptiaca and Zygophyllum simplex. Phoenix dactylifera is cultivated in local areas covered with sandy sheets. Between the date palm trees there is a thin growth of Cyperus conglomeratus. Some plant species have been analysed chemically to determine their main constituents. The relationships between the environmental factors and the plant life of the islands are discussed.

    To evaluate hypersensitivity to Dermatophagoides pteronyssinus (D. pteronyssinus) and Dermatophagoides farinae (D. farinae) in pediatric patients with asthma, and the use of acaricides. This is a randomized controlled trial in 82 asthmatic children. They were recruited and evaluated for severity and chronicity according to the Global Initiative for Asthma Guidelines. The study was carried out in the Pediatric Allergy Clinic, Al Noor Hospital, Khalifa Branch, Abu Dhabi, United Arab Emirates between September 2008 and June 2010. Skin prick test (SPT) was performed including D. pteronyssinus and D. farinae, and for those who were sensitive to one, or the other. The therapeutic value of acaricides was evaluated by assessing the severity of asthma before and after their use. Approximately 81.7% of asthmatics were sensitive to house dust mites (HDM). Hypersensitivity was associated with the more severe and persistent asthma (p=0.029). The manifested severity of asthma was not HDM species-specific. There was a linear association between response of children to acaricides and increasing severity of asthma. Hypersensitivity to HDM is an important factor for persistent and severe forms of asthma. Acaricides can help control childhood asthma, and we recommend SPT as part of the routine work-up of patients with asthma to determine HDM sensitive patients that can benefit from acaricides use.

    This paper does not necessarily reflect the views of the International Commission on Radiological Protection. Naturally occurring radioactive material (NORM) is produced during exploration and production operations of subsidiaries of the Abu Dhabi National Oil Company (ADNOC) in the United Arab Emirates, and accumulates in drilling tubulars, plant equipment, and components. These NORM hazardous wastes need to be managed in such a way that they do not damage human health and the environment. The primary radionuclides of concern in the oil and gas industries are radium-226 and radium-228. These radioisotopes are the decay products of uranium and thorium isotopes that are present in subsurface formations from which hydrocarbons are produced. While uranium and thorium are largely immobile, radium is slightly more soluble and may become mobilised in the fluid phases of the formation (International Association of Oil & Gas Producers, 2008). In order to treat and dispose of NORM waste products safely, ADNOC's subsidiary 'TAKREER' is developing a new facility, on behalf of all ADNOC subsidiaries, within the existing Central Environmental Protection Facilities (BeAAT) in Ruwais city. The NORM plant is envisaged to treat, handle, and dispose of NORM waste in the forms of scale, sludge, and contaminated equipment. The NORM treatment facility will cover activities such as decontamination, volume reduction, NORM handling, and concrete immobilisation of NORM waste into packages for designated landfilling. © The International Society for Prosthetics and Orthotics Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    Effective and efficient medication reporting processes are essential in promoting patient safety. Few qualitative studies have explored reporting of medication errors by health professionals, and none have made reference to behavioural theories. The objective was to describe and understand the behavioural determinants of health professional reporting of medication errors in the United Arab Emirates (UAE). This was a qualitative study comprising face-to-face, semi-structured interviews within three major medical/surgical hospitals of Abu Dhabi, the UAE. Health professionals were sampled purposively in strata of profession and years of experience. The semi-structured interview schedule focused on behavioural determinants around medication error reporting, facilitators, barriers and experiences. The Theoretical Domains Framework (TDF; a framework of theories of behaviour change) was used as a coding framework. Ethical approval was obtained from a UK university and all participating hospital ethics committees. Data saturation was achieved after interviewing ten nurses, ten pharmacists and nine physicians. Whilst it appeared that patient safety and organisational improvement goals and intentions were behavioural determinants which facilitated reporting, there were key determinants which deterred reporting. These included the beliefs of the consequences of reporting (lack of any feedback following reporting and impacting professional reputation, relationships and career progression), emotions (fear and worry) and issues related to the environmental context (time taken to report). These key behavioural determinants which negatively impact error reporting can facilitate the development of an intervention, centring on organisational safety and reporting culture, to enhance reporting effectiveness and efficiency.

    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. - Highlights: • A compact system for real time displaying of muon tracks is presented. • The system is based on scintillating plates composed of doped polystyrene bars. • By using SiPMs and corresponding LEDs the muon paths can be visualized. • The purpose of this system is to introduce the public to sub-nuclear particles.

    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.

    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.

    Development of Zakum Development Co.'s Upper Zakum oil reservoir off Abu Dhabi over the next few years will involve an over-all investment of more than $2 billion, about 25% of which will be for installing a 900 km pipeline system to gather the oil and transmit it to Zirku Island for offshore loading into tankers. A new pipeline network (called Z-3) will be built on top of and around two existing pipeline systems serving the Lower Zakum reservoir. The Upper Zakum Z-3 system will gather crude oil from more than 70 well head structures to three satellite platforms where gas separation is performed. The oil and associated gas will be transmitted to a central production complex via 24 in. dia trunklines (total about 97 km). The 4-12 in. dia flowlines will total around 595 km. A 60 km, 42 in. dia main oil line will link the central complex to Zirku Island, where two 17 km, 48 in. dia offshore loading lines, connected to two large single point moorings, will load 350,000 dwt tankers at 100,000 bbl/hr. The construction of the pipeline is described and the contractors for the project and their responsibilities are given.

    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.

    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.

    Full Text Available Rev.esc.adm.neg All disasters are said to follow a cyclical pattern referred to as the disaster cycle. The cycle is an overall view of stages within a continual loop of prevention, mitigation, preparedness, response and recovery. Disaster preparedness is one of the stages of the disaster management cycle guided in a manner that adequately protects communities. It involves the identification of potential hazards and vulnerabilities through risk assessments, forecast development and warning systems, modelling and training for a number of disaster scenarios of different hazards and at different magnitudes, development of insurance infrastructure and the growth of an intelligent community. The energy sector dominates in the UAE and consists of various assets - electricity, oil and natural gas that are geographically dispersed and connected by systems and networks. The protection of these systems and assets and within the energy sector especially, the safeguarding of oil and gas infrastructure from any and all internal and external threats should become top priority in the UAE. Threats to geopolitical and economic stability that need to be considered and prepared to include tectonic activity, climate change, nuclear energy, terrorism and war. This paper discusses the current level of resilience in the Emirati energy sector and what can be done to improve it. The secondary data was taken from various academic and professional sources whilst the primary data, which constitutes 35 questionnaires with both qualitative and quantitative data, were collected on site at two electricity generating plants, one in Abu Dhabi and one in Dubai.

    A population-based survey of 742 United Arab Emirates women aged 40 years and over who had attained natural menopause (amenorrhea of at least 6 months' duration) investigated age at onset and the prevalence of climacteric symptoms. Women from both urban and rural areas of Al-Ain City and Abu Dhabi, Dubai, and Sharjah Emirates were recruited through use of the multi-stage stratified cluster sampling technique. The median age at menopause in this sample was 48 years (mean, 47.3 +or- 3.29 years; range, 40-59 years)--significantly lower than the 50.3 year mean recorded among Western women. Median age at menopause was significantly associated with that of the mother (p 0.001) and older sister (p 0.001), parity (p 0.0001), and a history of use of oral contraceptives for more than 1 year (p 0.001). 394 women (53%) reported at least one climacteric symptom. Most common were hot flushes, reported by 47% of women. 145 women (19.5%) were currently taking hormone replacement therapy. The relatively low age at menopause in this population could reflect additional social, economic, environmental, or genetic factors that were not explored in this study.

  12. Tales of two cities: political capitals and economic centres in the world city network.

    Full Text Available The majority of major cities in the world city network are capital cities. Between primacy and political specialization there are examples of countries where the capital city and a second city remain as major rival cities in contemporary globalization. In this paper we focus upon situations where the capital city is less important in global economic capacity: Rome and Milan, Berlin and Frankfurt, Abu Dhabi and Dubai, Delhi and Mumbai, Islamabad and Karachi. This is an exercise in double comparisons: between cities in each pairing and between the pairings. Despite the massive differences – economic, cultural and political – amongst our chosen pairs of cities we have found communalities relating to the specific circumstance we are investigating. First, there is some evidence that economic centres are more global and less local than their capital cities. Second, more particularly, we have shown that in terms of global economic connections there is a very consistent pattern: economic centres have a much more coherent and telling integration into the world city network.

    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.

  14. Dealing with the Problem of Cybercrime

    Alkaabi, Ali; Mohay, George; McCullagh, Adrian; Chantler, Nicholas

    Lack of a universally accepted and comprehensive taxonomy of cybercrime seriously impedes international efforts to accurately identify, report and monitor cybercrime trends. There is, not surprisingly, a corresponding disconnect internationally on the cybercrime legislation front, a much more serious problem and one which the International Telecommunication Union (ITU) says requires 'the urgent attention of all nations'. Yet, and despite the existence of the Council of Europe Convention on Cybercrime, a proposal for a global cybercrime treaty was rejected by the United Nations (UN) as recently as April 2010. This paper presents a refined and comprehensive taxonomy of cybercrime and demonstrates its utility for widespread use. It analyses how the USA, the UK, Australia and the UAE align with the CoE Convention and finds that more needs to be done to achieve conformance. We conclude with an analysis of the approaches used in Australia, in Queensland, and in the UAE, in Abu Dhabi, to fight cybercrime and identify a number of shared problems.

    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.

    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)

    This study was undertaken in order to determine the availability and chemical composition of potentially lead-toxic traditional eye cosmetics ("kohls") in six of the seven emirates of the United Arab Emirates (UAE). Thus of especial interest was the percentage of the purchased samples that contained the toxic element lead. A total of 53 observably different kohl samples were found to be available overall in the six emirates: Dubai, Sharjah, Ajman, Umm Al-Quwain, Ras Al-Khaimah, and Fujairah. It was found that 19 of these samples had been previously analyzed by us in studies covering Oman, Abu Dhabi (city), and Egypt (Cairo). The techniques of X-ray powder diffraction (XRPD) and scanning electron microscopy (SEM) were used to analyze the remaining 34 samples. Overall, for the 53 kohl samples, it was found that 20 (38%) contained a lead compound (galena, PbS) as the main component. The other main components were found to be one of the following: amorphous carbon, calcite/aragonite (CaCO3), goethite (FeO(OH)), hematite (Fe2O3), sassolite (H3BO3), talc (Mg3Si4O10(OH)2), or zincite (ZnO).

    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.

    Full Text Available The United Arab Emirates is experiencing a challenging turn towards sustainable social housing. Conventional neighborhood planning and design principles are being replaced by those leading to more sustainable urban forms. To trace this challenging move, the research has investigated the degree of consideration of sustainable urban design principles in two social housing neighborhoods in Al Ain City in Abu Dhabi Emirate, UAE. The first represents a conventional urban form based on the neighborhood theory; the other represents the new sustainable design. The ultimate aim is to define the obstacles hindering the full achievement of a sustainable urban form in this housing type. To undertake research investigations, a matrix of the design principles of sustainable urban forms has been initiated in order to facilitate the assessment of the urban forms of the two selected urban communities. Some qualitatively measurable design elements have been defined for each of these principles. The results of the analysis of the shift from ‘conventional’ to ‘sustainable’ case studies have revealed some aspects that would prevent the attainment of fully sustainable urban forms in newly designed social housing neighborhoods. Finally, the research concludes by recommending some fundamental actions to help meet these challenges in future design.

    The solar hourly global irradiation received at ground level estimated by the databases HelioClim-3v4, HelioClim-3v5 and CAMS Radiation Service are compared to coincident measurements made in five stations in Oman and Abu Dhabi. CAMS is an abbreviation of Copernicus Atmosphere Monitoring Service. Each database describes the hour-to-hour changes in irradiation very well with correlation coefficients greater than 0.97 for all stations. Each database exhibits a tendency to underestimate the irradiation in this area; the bias is small and less than 5 % of the average of the measurements in absolute value. The RMSE ranges between 70 and 90 Wh m-2 (11 to 16 %). This validation of the three databases for this arid region on the edge of the Meteosat coverage reveals satisfactory results. Each database captures accurately the temporal and spatial variability of the irradiance field. It is found that the three databases do not exhibit noticeable geographical changes in performances and are reliable sources to assess the SSI in this region.

    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.

    Estimates of daily electrical cooling load for a city of 800,000 are developed based on the relationship between weather variables and daily-average electricity consumption over 1 year. The relationship is found to be nearly linear above a threshold temperature. Temperature and humidity were found to be the largest, at 59%, and second largest, at 21%, contributors to electrical cooling load. Direct normal irradiation intercepted by a vertical cylinder, DNI sin {theta}, was found to be a useful explanatory variable when modeling aggregates of buildings without a known or dominant orientation. The best study case model used DNI sin {theta} and diffuse horizontal irradiation (DHI) as distinct explanatory variables with annual electrical cooling load contributions of 9% and 11% respectively. Although the seasonal variation in electrical cooling load is large - on peak summer days more than 1.5 times the winter base load - the combined direct and diffuse solar contribution is essentially flat through the year, a condition at odds with the common assumption that solar cooling always provides a good match between supply and demand. The final model gives an electrical cooling load estimate for Abu Dhabi Island that corresponds to 40% of the total annual electrical load and 61% on the peak day. (author)

    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.

    2016-03-09

    In 2013, the livestock population in the UAE exceeded 4.3 million heads with sheep and goats accounting for 90% of this. The overall number of captive wild ungulates (gazelle types) is difficult to assess as there is no registration system in place or enforced in the UAE with regard to the possession of wildlife. Those animal collections, mainly owned by high-ranking families, are therefore not registered and kept far from public viewing. Nonetheless, some collections are housing more than 30 000 ungulates in one location. The primary objective of this study was to describe the biosecurity measures currently applied in UAE ungulate facilities for different wildlife and livestock sectors. A secondary objective was to use the output from this biosecurity survey to investigate which sector could be categorized into risk groups for disease introduction and spread. Between October 2014 and May 2015, biosecurity questionnaire data were collected in the Emirates of Abu Dhabi, Dubai, Ras Al Khaimah, Fujeirah, Ajman, Umm al Quwain and Sharjah from 14 wildlife collections, 30 livestock farms and 15 mixed (wildlife and livestock farms). These investigations through questionnaires allowed us to quantify and assess statistically biosecurity practices and levels for both livestock and wildlife sectors. In both sectors, biosecurity measures could be improved and only a few facilities had high biosecurity scores. The group of small unregistered farms (Ezba) represented the highest risk of disease transmission to other animals due to their lack of biosecurity awareness.

    Full Text Available The fresh quality of a concrete mixture subjected to high temperature and prolonged mixing is adversely affected. These harsh conditions would result in a stiff concrete that is hard to handle and place. This paper investigates the coupled effects of temperature and prolonged mixing on green self-consolidating concrete (GSCC incorporating a ternary blend of fly ash and silica fume. This study was carried out in the construction material laboratory of Abu Dhabi University under an outdoor environment during the summer of 2014. The SCC mixtures were continuously mixed for 110 minutes at a temperature ranging from 25 to 40 °C to simulate the actual conditions of concrete during transporting to a construction site. The fresh properties were tested using BT2 portable rheometer, slump flow, T50 and visual stability index (VSI. The results showed that the ternary blend of silica fume and fly ash enhanced the rheological properties of SCC mixtures under high temperature and prolonged mixing time.

    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.

    Full Text Available Tra pochi giorni sarà trascorso un anno da quel 27 gennaio 2016 in cui 250 eminenti studiosi islamici, riuniti a Marrakech e provenienti da oltre 120 nazioni, hanno sottoscritto una “Dichiarazione sui diritti delle minoranze religiose nei Paesi a maggioranza musulmana” rivolgendo l’appello a sviluppare una giurisprudenza islamica sul concetto di cittadinanza inclusiva di tutti i gruppi religiosi. L’incontro si era tenuto su invito del Ministero della Promozione e degli Affari Islamici del Regno del Marocco e del Forum per la Promozione della Pace nelle società islamiche, con sede negli Emirati Arabi Uniti. All’evento avevano partecipato cinquanta leader di altre religioni e rappresentanti delle organizzazioni islamiche e internazionali. L’incontro proseguiva lungo il cammino tracciato ad Abu Dhabi nel 2014 con la nascita del Forum for peace, inteso a mostrare al mondo che l’Islam “is a religion of peace and justice”, cui aveva fatto seguito nel 2015 un secondo Forum inteso a ristabilire “the priorities of Muslim societies by rehabilitating hearts and intellects to a more thorough understanding of the salience of peace in Islam, the shariah, and our tradition”.

    - This review examines challenges and opportunities in preparing laboratories in a startup phase for accreditation by both College of American Pathologists (CAP) and International Organization for Standardization (ISO) 15189 in an international setting as it relates to our experience at Cleveland Clinic Abu Dhabi Laboratory. It also discusses some of the strategies used in executing those projects and the added advantages in perusing both types of accreditations. - To share our experience with CAP and ISO 15189 accreditations in a startup international operation in relation to the challenges encountered and implementation strategy success factors. - MEDLINE (PubMed) database was used to review this topic as well as peer-reviewed articles and World Health Organization publications on the topic. - Accreditation is a perfect means toward building quality medical laboratories in a diverse workforce environment and improving patient safety. Further, it establishes a strong foundation on which any new operation can build a sustainable quality improvement culture. Accreditations by CAP and/or ISO are among the most reputable and well-established accreditation systems that clinical laboratories could aim for. As a result of both accreditations offering synergistic and complementing features, we recommend that any laboratory seeking excellence in quality and performance should consider exploring both. Key elements to success include having dedicated project management and change management support while preparing for accreditation. Laboratories seeking accreditation in early operational stages may face a number of challenges; however, significant opportunities will also be present to optimize various operational components from the beginning.

    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.

    Full Text Available This paper presents data obtained from focus groups conducted to investigate male students’ experiences in higher education in the United Arab Emirates. Among the issues discussed by students was the impact of social networks addiction on student motivation and this paper focuses on that issue. Thirteen focus groups were conducted with 83 English as a Foreign Language male students at four government campuses including United Arab Emirates University at Al Ain Campus, Higher College of Technology at Ras Al-Khaima Campus, and two campuses (Abu Dhabi and Dubai of Zayed University. Students access social network sites for both educational and non-educational aspects. Students spoke about their experiences and how social network addiction influenced their academic motivation to study. The resulting themes from the focus groups show that social network addiction has had an impact on student class performance and in some cases led to class failure. Recommendation for better class management and intervention programs are suggested to policy makers and instructors to foster a better student learning experience.

    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.

    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.

    Full Text Available Between May 2007 and April 2009, 29 falcons with identically localized, yellowish discolored cutaneous lesions in the thigh and lateral body wall region were presented at Abu Dhabi Falcon Hospital. 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.

    In one of the gas processing facilities in Abu Dhabi, UAE; a case of 316L stainless steel material failure occurred in the fractionating column due to stress cracking corrosion twice in a cycle of less than 2 years. This paper studies the stress corrosion cracking behavior of the 316L stainless steel in an accelerated corrosion environment and compares it with a higher corrosion resistant nickel alloy (Inconel 625). The experimental work was designed according to ASTM G36 standard, the samples were immersed in a boiling magnesium chloride medium which provided the accelerated corrosion environment and the tested samples were shaped into U-bend specimens as they underwent both plastic and elastic stresses. The specimens were then tested to determine the time required for cracks to initiate. The results of the experimental work showed that the main mode of failure was stress corrosion cracking initiated by the proven presence of chlorides, hydrogen sulfide, and water at elevated temperatures. Inconel 625 samples placed in the controlled environment showed better corrosion resistance as it took them an average of 56 days to initiate cracks, whereas it took an average of 24 days to initiate cracks in the stainless steel 316L samples. The scanning electron microscopy (SEM) micrographs showed that the cracks in the stainless steel 316L samples were longer, wider, and deeper compared to the cracks of Inconel 625.

    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.

    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.

     In order to identify the utilizing potential and the environmental effect of ash from Merapi Mount eruption in 2010, determination of its chemical composition has been performed, including major, minor and trace elements. In addition,  pH of the ash, and iron concentration in rivers, wells, and  tower for water collection were also determined. The ash samples was taken in December 2010- January 2011, after the eruption stopped, located in Magelang, Sleman, and Klaten regions, in various distances from the summit.The results of the determination show that the Merapi Mt. ash contains major (Al, Si, Ca, and  Fe, minor (K, Mg, Mn, Na, P, S, and Ti, and  trace elements (Au ,As, Ba, Co, Cr, Cu, Mo, Ni, Pb, S, Sb, Sn, Sr, V, Zn, dan Zr.   The elements can be categorized into  widely used elements, i.e.   Al, Si, Ca, Fe, Ti, V, and  Zn, and economic high value element,  i.e.  Au, as well as  the environment and health negative affect elements  such as As, Cr, Cr, Cu, Pb, Ni, and S. It is also found that the  ash taken from different locations with farther distances from the mountain, has similar chemical composition.  Moreover, based on the large content of Al, Ca, and  Si  (around 56%, 4%, and  18 %respectively,  enabling the ash to be used as raw material for  cement or other cement based materials production. In addition, since Ti and Fe is also found in adequate level in the ash, it is also possible to extract the metals to get the pure one having wide and valuable functions. The presence of K and P, as fertilizer components, in the ash with significant amount, it is also interesting to evaluate the effect of the ash covering the soil on its fertile. However, the low pH of the ash is also observed that is due  to the presence of S in considerable amount, leading to the soil becomes unfertile. Although the hazard heavy (Pb, Cd, Cr, Cu, and Ni are found in the ash, the contamination of the metals in the rivers and wells are not detected.  Dispersion of the ash is also indicated to increase Fe content in the rivers and wells, but no effect in the water collected in the covered tower, enabling it to be used as drinking water. It is hoped that the detail chemical composition reported in this paper, is useful for further research and development in geological, civil and mineral engineering, agriculture, fishery, and environmental fields.

    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.

    Artificial neural networks (ANNs) have been widely used in predicting the severity of road traffic crashes. All available information about previously occurred accidents is typically used for building a single prediction model (i.e., classifier). Too little attention has been paid to the differences between these accidents, leading, in most cases, to build less accurate predictors. Hierarchical clustering is a well-known clustering method that seeks to group data by creating a hierarchy of clusters. Using hierarchical clustering and ANNs, a clustering-based classification approach for predicting the injury severity of road traffic accidents was proposed. About 6000 road accidents occurred over a six-year period from 2008 to 2013 in Abu Dhabi were used throughout this study. In order to reduce the amount of variation in data, hierarchical clustering was applied on the data set to organize it into six different forms, each with different number of clusters (i.e., clusters from 1 to 6). Two ANN models were subsequently built for each cluster of accidents in each generated form. The first model was built and validated using all accidents (training set), whereas only 66% of the accidents were used to build the second model, and the remaining 34% were used to test it (percentage split). Finally, the weighted average accuracy was computed for each type of models in each from of data. The results show that when testing the models using the training set, clustering prior to classification achieves (11%-16%) more accuracy than without using clustering, while the percentage split achieves (2%-5%) more accuracy. The results also suggest that partitioning the accidents into six clusters achieves the best accuracy if both types of models are taken into account.

    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

    Full Text Available Abstract Background Parental care often increases offspring survival, but is costly to the parents. A trade-off between the cost and benefit of care is expected, so that when care provisioning by both parents is essential for the success of young, for instance in extremely cold or hot environments, the parents should rear their young together. We investigated the latter hypothesis in a ground nesting shorebird, the Kentish plover Charadrius alexandrinus in an extremely hot environment, the Arabian Desert. Midday ground temperature was often above 50°C in our study site in Abu Dhabi (United Arab Emirates, thus leaving the eggs unattended even for a few minute risks overheating and death of embryos. Results Through the use of video surveillance systems we recorded incubation routines of male and female Kentish plovers at 28 nests over a full day (24 h. We show that ambient temperature had a significant influence on incubation behaviour of both sexes, and the relationships are often non-linear. Coordinated incubation between parents was particularly strong in midday with incubation shared approximately equally between the male and the female. The enhanced biparental incubation was due to males increasing their nest attendance with ambient temperature. Conclusions Our results suggest biparental care is essential during incubation in the Kentish plover in extremely hot environments. Shared incubation may also help the parents to cope with heat stress themselves: they can relieve each other frequently from incubation duties. We suggest that once the eggs have hatched the risks associated with hot temperature are reduced: the chicks become mobile, and they gradually develop thermoregulation. When biparental care of young is no longer essential one parent may desert the family. The relaxed demand of the offspring may contribute to the diverse breeding systems exhibited by many shorebirds.

    The aims of this study were to quantify the behavioural determinants of health professional reporting of medication errors in the United Arab Emirates (UAE) and to explore any differences between respondents. A cross-sectional survey of patient-facing doctors, nurses and pharmacists within three major hospitals of Abu Dhabi, the UAE. An online questionnaire was developed based on the Theoretical Domains Framework (TDF, a framework of behaviour change theories). Principal component analysis (PCA) was used to identify components and internal reliability determined. Ethical approval was obtained from a UK university and all hospital ethics committees. Two hundred and ninety-four responses were received. Questionnaire items clustered into six components of knowledge and skills, feedback and support, action and impact, motivation, effort and emotions. Respondents generally gave positive responses for knowledge and skills, feedback and support and action and impact components. Responses were more neutral for the motivation and effort components.

    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 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.

    A highly sensitive method for simultaneous determinations of eleven β-blockers and β-agonists in distilled and waste-waters using liquid chromatography-electrospray ionization-tandem mass spectrometry (LC-ESI-MS-MS) was developed, optimized and validated. The method was used for trace determinations of acebutolol, atenolol, metoprolol, propranolol, timolol, nadolol, labetalol, oxprenolol, pindolol, alprenolol and terbutaline. Oasis MCX and Clean Screen cartridges were used for solid phase extractions and an alkaline mixture of dichloromethane-propanol was used as mobile phase. Matrix effect was reduced by using methanol as a pre-eluant for removing co-extractives on the SPE cartridges and by applying the internal standard method for quantification. Using Oasis MCX-SPE cartridges, developed method gave average recoveries of 77.20-97.30% for drugs spiked at 150.00-500.00pg/ml. Intra-day precisions gave RSD of 3.367-12.489% while as inter-day precisions gave RSD of 6.425-19.768%. Detection limits of 0.11-6.74pg/ml and quantification limits of 0.14-22.88pg/ml were obtained. Signal's suppression in the range of 4.50-24.50% was recorded due to the matrix effect. Drugs spiked in wastewater at 500.00pg/ml concentrations level and stored at 4°C for 6 days, showed insignificant degradation. Developed method was successfully applied to the analysis of pharmaceutical residues in effluents wastewaters. Five β-blockers and one β-agonists were detected in Al-Ain and Abu Dhabi wastewaters at average concentrations of 3.44-19.05pg/ml. Atenolol was detected at higher average concentration ranged in 125.60-234.28pg/ml. Results obtained suggest that adopted wastewater treatment processes are not enough to degrade these compounds.

    2016-11-01

    We conducted four core-flood experiments on samples of a micritic, reef limestone from Abu Dhabi under conditions of constant flow rate. The pore fluid was water in equilibrium with CO2, which, because of its lowered pH, is chemically reactive with the limestone. Flow rates were between 0.03 and 0.1 mL/min. The difference between up and downstream pore pressures dropped to final values ≪1 MPa over periods of 3-18 h. Scanning electron microscope and microtomography imaging of the starting material showed that the limestone is mostly calcite and lacks connected macroporosity and that the prevailing pores are few microns large. During each experiment, a wormhole formed by localized dissolution, an observation consistent with the decreases in pressure head between the up and downstream reservoirs. Moreover, we numerically modeled the changes in permeability during the experiments. We devised a network approach that separated the pore space into competing subnetworks of pipes. Thus, the problem was framed as a competition of flow of the reactive fluid among the adversary subnetworks. The precondition for localization within certain time is that the leading subnetwork rapidly becomes more transmissible than its competitors. This novel model successfully simulated features of the shape of the wormhole as it grew from few to about 100 µm, matched the pressure history patterns, and yielded the correct order of magnitude of the breakthrough time. Finally, we systematically studied the impact of changing the statistical parameters of the subnetworks. Larger mean radius and spatial correlation of the leading subnetwork led to faster localization.

    2012-01-01

    Background: Environmental risks to health in the United Arab Emirates (UAE) have shifted rapidly from infectious to noninfectious diseases as the nation has developed at an unprecedented rate. In response to public concerns over newly emerging environmental risks, the Environment Agency–Abu Dhabi commissioned a multidisciplinary environmental health strategic planning project. Objectives: In order to develop the environmental health strategic plan, we sought to quantify the illnesses and premature deaths in the UAE attributable to 14 environmental pollutant categories, prioritize these 14 risk factors, and identify interventions. Methods: We estimated the disease burden imposed by each risk factor using an attributable fraction approach, and we prioritized the risks using an empirically tested stakeholder engagement process. We then engaged government personnel, scientists, and other stakeholders to identify interventions. Results: The UAE’s environmental disease burden is low by global standards. Ambient air pollution is the leading contributor to premature mortality [~ 650 annual deaths; 95% confidence interval (CI): 140, 1,400]. Risk factors leading to > 10,000 annual health care facility visits included occupational exposures, indoor air pollution, drinking water contamination, seafood contamination, and ambient air pollution. Among the 14 risks considered, on average, outdoor air pollution was ranked by the stakeholders as the highest priority (mean rank, 1.4; interquartile range, 1–2) and indoor air pollution as the second-highest priority (mean rank 3.3; interquartile range, 2–4). The resulting strategic plan identified 216 potential interventions for reducing environmental risks to health. Conclusions: The strategic planning exercise described here provides a framework for systematically deciding how to invest public funds to maximize expected returns in environmental health, where returns are measured in terms of reductions in a population

  11. Density-driven free-convection model for isotopically fractionated geogenic nitrate in sabkha brine

    Wood, Warren W.; Böhlke, John Karl

    2017-01-01

    Subsurface brines with high nitrate (NO3−) concentration are common in desert environments as atmospheric nitrogen is concentrated by the evaporation of precipitation and little nitrogen uptake. However, in addition to having an elevated mean concentration of ∼525 mg/L (as N), NO3− in the coastal sabkhas of Abu Dhabi is enriched in 15N (mean δ15N ∼17‰), which is an enigma. A NO3− solute mass balance analysis of the sabkha aquifer system suggests that more than 90% of the nitrogen is from local atmospheric deposition and the remainder from ascending brine. In contrast, isotopic mass balances based on Δ17O, δ15N, and δ18O data suggest approximately 80 to 90% of the NO3− could be from ascending brine. As the sabkha has essentially no soil, no vegetation, and no anthropogenic land or water use, we propose to resolve this apparent contradiction with a density-driven free-convection transport model. In this conceptual model, the density of rain is increased by solution of surface salts, transporting near-surface oxygenated NO3− bearing water downward where it encounters reducing conditions and mixes with oxygen-free ascending geologic brines. In this environment, NO3− is partially reduced to nitrogen gas (N2), thus enriching the remaining NO3− in heavy isotopes. The isotopically fractionated NO3− and nitrogen gas return to the near-surface oxidizing environment on the upward displacement leg of the free-convection cycle, where the nitrogen gas is released to the atmosphere and new NO3− is added to the system from atmospheric deposition. This recharge/recycling process has operated over many cycles in the 8000-year history of the shallow aquifer, progressively concentrating and isotopically fractionating the NO3−.

    Strong sensible heat fluxes and deep turbulent mixing - together with marked dustiness and a low substrate water content - represent a characteristic signature of the atmospheric boundary layer (ABL) over hot deserts, resulting in "thicker" mixing layers and peculiar optical properties. Beside these main common features however, desert boundary layers present extremely complex local structures that have been scarcely addressed in the literature, and whose understanding is essential in modeling processes such as transport and deposition of dust and pollutants, local wind fields, turbulent fluxes and their impacts on the sustainable development, human health and solar energy harvesting in these regions. In this study, we explore the potential of the joint usage of Lidar Ceilometer backscattering profiles and sun-photometer optical depth retrievals to quantitatively determine the vertical aerosol profile over dusty hot desert regions. Toward this goal, we analyze a continuous record of observations of the atmospheric boundary layer height from a single lens LiDAR ceilometer operated at Masdar Institute Field Station (24.4425N 54.6163E, Abu Dhabi, United Arab Emirates), starting March 2013, and the concurrent measurements of aerosol optical depth derived independently from the Masdar Institute AERONET sun-photometer. The main features of the desert ABL are obtained from the ceilometer range corrected backscattering profiles through bi-dimensional clustering technique we developed as a modification of the recently proposed single-profile clustering method, and therefore "directly" and "indirectly" calibrated to obtain a full diurnal cycle climatology of the aerosol optical depth and aerosol profiles. The challenges and the advantages of applying a similar methodology to the monitoring of aerosols and dust over hyper-arid regions are also discussed, together with the issues related to the sensitivity of commercial ceilometers to changes in the solar background.

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.

    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 Abstract Background Despite its high incidence among children under the age of five, little is known about the burden of pediatric gastroenteritis outside the medical setting. The objective of this study was to describe the burden of acute gastroenteritis among children residing in the United Arab Emirates, including those not receiving medical care. Methods A quantitative cross-sectional survey of 500 parents of children under 5 years of age who had suffered from acute gastroenteritis the preceding three months was conducted in the cities of Abu Dhabi and Al Ain. Data collected included respondent characteristics, disease symptoms, medical care sought, and parental expenditures and work loss. Data were analyzed using parametric and non-parametric statistical methods. Results Vomiting and diarrhea episodes lasted on average between 3 and 4 days. Overall, 87% of parents sought medical care for their children; 10% of these cases required hospitalization with an average length of stay of 2.6 days. When medical care was sought, the average parental cost per gastroenteritis episode was US$64, 4.5 times higher than with home care only (US$14. Nearly 60% of this difference was attributable to co-payments and medication use: 69% of children used oral rehydration solution, 68% antiemetics, 65% antibiotics and 64% antidiarrheals. Overall, 38 parents missed work per 100 gastroenteritis episodes for an average of 1.4 days. Conclusions Given its high incidence, pediatric gastroenteritis has an important financial and productivity impact on parents in the United Arab Emirates. To reduce this impact, efforts should be made both to prevent acute gastroenteritis and to optimize its treatment.

  18. Assessing the benefits of the integration of location information in e-Government

    Over the past years more and more geospatial data have been made readily accessible for different user communities as part of government efforts to set-up Spatial Data Infrastructures. As a result users from different sectors can search, find and bind spatial information and combine it with their own data resources and applications. However, too often, spatial data applications and services remain organised as separate silos, not well integrated in the business processes they are supposed to support. The European Union Location Framework (EULF), as part of the Interoperability Solutions for European Public Administrations (ISA) Programme of the EU (EC-DG DIGIT), aims to improve the integration of location information in e-Government processes through a better policy and strategy alignment, and through the improved legal, organisational, semantic and technical interoperability of data and systems. The EULF seeks to enhance interactions between Governments, Businesses and Citizens with location information and location enabled services and to make them part of the more generic ICT infrastructures of public administrations. One of the challenges that arise in this context is to describe, estimate or measure the benefits and added value of this integration of location information in e-Government. In the context of the EULF several existing approaches to assess the benefits of spatially enabled services and applications in e-Government have been studied. Two examples will be presented, one from Denmark, the other from Abu Dhabi. Both served as input to the approach developed for the EULF. A concrete case to estimate benefits at service and process level will be given with the aim to respond questions such as "which indicators can be used and how to measure them", "how can process owners collect the necessary information", "how to solve the benefits attribute question" and "how to extrapolate findings from one level of analysis to another"?

    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.

    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.

    A critical incident stress debriefing (CISD) was conducted with two U.S. Army military police officers (MPs) and 11 Iraqi detainees who experienced the untimely death of a detainee. The CISD was conducted by a psychiatrist and a psychologist, who used the seven-step debriefing model created by Jeffrey Mitchell in 1983. A primary goal of CISD is to diminish the impact of a traumatic event and ultimately to prevent the onset of post-traumatic stress disorder. An unexpected finding was that the debriefing provided an opportunity for the MPs and detainees to clear preconceived notions about each other, enhancing mutual collaboration. The purpose of this article is to describe how a mental health team used a CISD as an intervention in treating MPs and detainees who experienced a common tragic event.

    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.

    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.

    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.

    2010-12-15

    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

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.

    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

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

This report represents the consensus of 22 relevant medical specialists from Africa and the Middle East region engaged in the management of RCC. Partial or radical nephrectomy is the standard of care for most patients with localized RCC. It is essential that patients are followed up appropriately after surgery to enable local and distant relapses to be identified and treated promptly. The treatment of advanced/metastatic disease has changed dramatically with the introduction of targeted therapies. Follow-up of these patients enables therapy optimization and assessment of response to treatment. There was universal agreement on the importance of management of RCC by a multidisciplinary team supported by a multidisciplinary tumor board. Barriers hindering this approach were identified. These included lack of awareness of the benefits of multidisciplinary team role, poor communication among relevant disciplines, time constraints, and specifics of private practice. Other challenges include shortage of expert specialists as urologists and oncologists and lack of local management guidelines in some countries. Solutions were proposed and discussed. Medical

Substantial clinical and experimental evidence suggest that both diabetes and insulin resistance cause a combination of endothelial dysfunctions, which may diminish the anti-atherogenic role of the vascular endothelium. Both insulin resistance and endothelial dysfunction appear to precede the development of overt hyperglycemia in patients with type 2 diabetes. Therefore, in patients with diabetes or insulin resistance, endothelial dysfunction may be a critical early target for preventing atherosclerosis and cardiovascular disease. Microalbuminuria is now considered to be an atherosclerotic risk factor and predicts future cardiovascular disease risk in diabetic patients, in elderly patients, as well as in the general population. It has been implicated as an independent risk factor for cardiovascular disease and premature cardiovascular mortality for patients with type 1 and type 2 diabetes mellitus, as well as for patients with essential hypertension. A complete biochemical understanding of the mechanisms by which hyperglycemia causes vascular functional and structural changes associated with the diabetic milieu still eludes us. In recent years, the numerous biochemical and metabolic pathways postulated to have a causal role in the pathogenesis of diabetic vascular disease have been distilled into several unifying hypotheses. The role of chronic hyperglycemia in the development of diabetic microvascular complications and in neuropathy has been clearly established. However, the biochemical or cellular links between elevated blood glucose levels, and the vascular lesions remain

    Many areas in the world experience periodic water shortages due to meteorological drought, salt water intrusion or over-exploitation of the water resources. Recently, it was established that the depletion of aquifers in many areas of the world is in an advanced state (Gleeson et al, 2012). This poses enormous challenges as 2.5 billion people and many companies depend on groundwater now and in the future (UN, 2015; ESG, 2016). A solution to increase robustness of water systems and prevent water shortage is subsurface storage of water during wet periods using Managed Aquifer Research (MAR). In addition to mitigation of water shortage, MAR can also reduce the occurrence and degree of flooding. Here, we present an overview of Deltares MAR expertise and available tools for up-scaling MAR. Deltares has experience with both research and implementation of MAR in different parts of the world under various hydro(geo)logical, climatic and socio-economic conditions. Various MAR techniques were assessed/tested in coastal areas of the Netherlands, Spain, New York, New Orleans and in Bangladesh. In some of these areas specific groundwater shortage related issues occur, such as salt water intrusion or subsidence. In Singapore, monitoring campaigns and modeling were done to design MAR by infiltration of water in over-exploited aquifers. In Abu Dhabi, geophysical methods were used to detect the optimal conditions for MAR systems. To effectively increase the robustness of groundwater systems up-scaling of MAR is required. For this purpose, Deltares developed tools that provide insight in the potential demand, possibilities and effectiveness of MAR at larger scales. The Quick scan tool for Fresh Groundwater Buffering provides insight on regional to national scale and is based on GIS-information of water demand, water resources, and subsurface properties. This quick scan tool has been applied for Mozambique, Kenya, India and Bangladesh. The Fresh Water Optimizer assesses the

    Full Text Available Branding represents the instrument through which an entity communicates and identifies itself in the consumer’s perception. National branding is a similar mean employed at country level. Nation branding is crucial in order to attract investment, boost exports and attract tourists and talented workforce. Nation branding stands between public diplomacy and economic benefits. An adequate policy of Nation Branding-based on a positive, credible and economically reliable image- can be able to extend the range of potential customers and of potential investors. With the aim of better understanding the new challenges, opportunities and threats existent in a globalized economy, the paper evaluates nation branding in the context of UAE and Qatar. The paper examines nation-branding as a driver for boosting the economy, taking into account that clichés and stereotypes (especially in the context of the Middle East can influence our perception towards one country or another. The analysis explores the strategy adopted in order that Dubai becomes the flagship-brand of the UAE. Abu Dhabi complements this strategy, driving UAE to the position of the most valuable brand in the Middle East. The paper further enquires the case of Qatar and compares it with the branding process of the UAE. Qatar has established various branding resources such as the Al Jazeera news network, international sport events and several cultural and educational exchange programs with international profile. The UAE strives to become an influencer in the global economy, overriding its dependence on hydrocarbon reserves. Qatar is richer in hydrocarbon reserves than the UAE; nevertheless, it shares the interest of detaching itself from the rentier economy. The study explores the fact that from 2014-onwards the global oil economy was hit hard, as the price of the oil barrel is at an historic low, thus it has become stringent for the Persian Gulf countries to diversify the revenue sources.

    The distribution of larger benthic foraminifera in Recent littoral environment of the United Arab Emirates (Abu Dhabi and Western regions) was investigated with the aim of understanding the response of those foraminifera to an increase in water salinity. For this purpose, 100 sediment samples from nearshore shelf, beach-front, channel, lagoon, and intertidal environment were collected. Sampling was undertaken at a water depth shallower than 15 m in water with a temperature of 22 to 35˚C, a salinity ranging from 40 to 60‰ and a pH of 8. Samples were stained with rose Bengal at the moment of sample collection in order to identify living specimens. The most abundant epiphytic larger benthic foraminifera in the studied area were Peneroplis pertusus and P. planatus with less common Spirolina areatina, S. aciculate and Sorites marginalis. The living specimens of the above mentioned species with normal test growing were particularly abundant in the nearshore shelf and lagoonal samples collected on seaweed. Dead specimens were concentrated in the coarser sediments of the beach-front, probably transported from nearby environments. Shallow coastal ponds are located in the upper intertidal zone and have a maximum salinity of 60‰ and contain abundant detached seagrass. Samples collected from these ponds possess a living foraminifera assemblage dominated by Peneroplis pertusus and P. planatus. High percentages (up to 50% of the stained assemblage) of Peneroplis presented abnormality in test growth, such as the presence of multiple apertures with reduced size, deformation in the general shape of the test, irregular suture lines and abnormal coiling. The high percentage of abnormal tests reflects natural environmental stress mainly caused by high and variable salinity. The unique presence of living epiphytic species, suggests that epiphytic foraminifera may be transported into the pond together with seagrass and continued to live in the pond. This hypothesis is supported by

    Microbial mat ecosystems have been operating at the sediment-fluid interface for over 3400 million years, influencing the flux, transformation and preservation of carbon from the biosphere to the physical environment. These ecosystems are excellent recorders of rapid and profound changes in earth surface environments and biota as they often survive crisis-induced extreme paleoenvironmental conditions. Their biosignatures, captured in the preserved organic matter and the biominerals that form the microbialite rock, constitute a significant tool in understanding geobiological processes and the interactions of the microbial communities with sediments and with the prevailing physical chemical parameters, as well as the environmental conditions at a local and global scale. Nevertheless, the exact pathways of diagenetic organic matter transformation and early-lithification, essential for the accretion and preservation in the geological record as microbialites, are not well understood. The Abu Dhabi coastal sabkha system contains a vast microbial mat belt that is dominated by continuous polygonal and internally-laminated microbial mats across the upper and middle intertidal zones. This modern system is believed to be the best analogue for the Upper Jurassic Arab Formation, which is both a prolific hydrocarbon reservoir and source rock facies in the United Arab Emirates and in neighbouring countries. In order to characterise the processes that lead to the formation of microbialites we investigated the modern and Jurassic system using a multidisciplinary approach, including growth of field-sampled microbial mats under controlled conditions in the laboratory and field-based analysis of microbial communities, mat mineralogy and organic biomarker analysis. In this study, we focus on hydrocarbon biomarker data obtained from the surface of microbial mats actively growing in the intertidal zone of the modern system. By comparing these findings to data obtained from recently

    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

    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

    The epidemiological, clinical, and biochemical profile of non-cerebral coenurosis in goats and the morphological characteristics of the responsible metacestodes (cysts) were examined in a cross-sectional survey of slaughtered goats in abattoirs of the United Arab Emirates (U.A.E.) originating from Abu Dhabi and various tropical countries. The age, country of origin, and location of each cyst in the body of goats were recorded. Blood samples collected from infected and matching healthy goats were subjected to biochemical analysis. Data on the morphological characteristics of the cysts as well as the clusters, scoleces, and rostellar hooks in one cyst from each affected carcass were collected. The data collected were subjected to statistical analysis. A total of 2,284 slaughtered goats were examined and 40 goats were diagnosed as infected with non-cerebral coenurus cysts. The prevalence of non-cerebral coenurosis was 1.75% and the degree of parasite aggregation (k) was 0.003, which is indicative of overdispersion (kgoats were palpation of large single cysts in thigh muscles and higher serum aspartate aminotransferase (AST) value.

    Asymptomatic bacteriuria (ABU) is common and often leads to unnecessary antimicrobial use. Reducing antibiotic overuse for ABU is therefore an important issue for antimicrobial stewardship. We performed this study to investigate the appropriateness of ABU management and to evaluate physicians' knowledge and practice regarding ABU. We reviewed all urine cultures of ≥10(5) cfu/mL of bacteria among inpatients in a 900-bed hospital in 2011. Each episode of bacteriuria was classified into ABU or urinary tract infection (UTI). ABU was defined as a positive urine culture (≥10(5) cfu/mL) without symptoms or signs suggesting UTI. In October 2012 a cross-sectional survey of resident physicians was undertaken using an anonymous, self-administered questionnaire. We identified 219 ABU cases among 1167 positive urine cultures, of which 70 (32.0 %) were inappropriately treated. Female gender, old age, pyuria, hematuria, and positive nitrite on urinalysis were associated with inappropriate ABU treatment in a multivariate analysis (P < 0.05). The response rate to the survey was 74.2 % (95/128). The mean knowledge score was 37.3 %, and 33.7 % of respondents were able to distinguish ABU from UTI, but less than half knew the indications for treating ABU. Even after ABU was correctly diagnosed, concerns about postoperative infections (38.6 %), UTI (9.1 %), and abnormal urinalysis (29.5 %) prevented proper management. About half of the respondents reported to prescribing antibiotics for ABU despite knowing they were not indicated. About one third of ABUs were inappropriately managed. Lack of knowledge and discrepancies between knowledge and practice, contributed to antimicrobial overuse for ABU. Our findings highlight the importance of developing interventions, including education, audit and feedback, to tackle the problem of inappropriate treatment of ABU.

    Full Text Available Rice husk ash as desiccation material can be used to maintain seed viability in storage through its ability to absorb humidity during its storage. High relative humidity caused seed moisture content to increase so the respiration rate of seed increases and uses faster food stock. Finally the viability of seed is lost. A research on use of rice husk ash as desiccation material of cocoa seed storage was conducted in Agronomy Laboratory and Kaliwining Experimental Station, Indonesian Coffee and Cocoa Research Institute. Completely Randomized Design was used in this research with treatment of rice husk ash application on cocoa seed as follows: 0 g/100 seeds (A, 5 g/100 seeds (B, 10 g/100 seeds (C, 15 g/100 seeds (D, and 20 g/100 seeds (E. This experiment used four replications. Cocoa seeds were stored in plastic bag within carton box in ambient temperature. The storage periods were 1, 2, and 3 weeks, and parameters of observation consisted of electrical conductivity of dipped water of cocoa seeds, percentage of seed germination, percentage of seed emergence, early growth parameters at one month old including seedlings height of seedling, diameter, leaf number, root length, and dry weight. The result of the experiment showed that the use of rice husk ash at 5-10 g/100 seeds could maintain electrical conductivity of dipped water at low level, percentage of seed germination at 99-100 % and percentage of seed emergence at 79-91% after two weeks storage. The use of rice husk ash at 5-10 g/100 seeds after two weeks storage affected height of cacao seedling, but did not affected stem diameters, leaf numbers, root lengths, and dry weights

    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.

    Asymptomatic bacteriuria (ABU) is a common clinical condition that often leads to unnecessary antimicrobial use. The reduction of antibiotic overuse for ABU is consequently an important issue for antimicrobial stewardship and to reduce the emergence of multidrug resistant strains. There are two issues in everyday urological practice that require special attention: the role of ABU in pre-operative prophylaxis and in women affected by recurrent urinary tract infections (rUTIs). Nowadays, this is the time to think over our practice and change our way of thinking. Here, we aimed to summarize the current literature knowledge in terms of ABU management in patients undergoing urological surgery and in patients with rUTIs. In the last years, the approach to patient with ABU has changed totally. Prior to all surgical procedures that do not enter the urinary tract, ABU is generally not considered as a risk factor, and screening and treatment are not considered necessary. On the other hand, in the case of all procedures entering the urinary tract, ABU should be treated in line with the results of a urine culture obtained before the procedure. In patients affected by rUTIs, ABU can even have a protective role in preventing symptomatic recurrence, particularly when Enterococcus faecalis (E. faecalis) has been isolated.

    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, marine organisms with the highest (210)Po concentration found in Marica marmorata (193.5-215.6 Bq kg(-1) dry weight).

    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

  2. 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., absorption refrigeration unit for gas turbine inlet air cooling, which would result in additional electric or mechanical power generation, and pre-cooling of process gas, which could reduce the need for or eliminate air coolers, as well as reduce propane chiller load, and ii) serve for heating of lean gas, which would reduce furnace load. At ASAB1, it is proposed that exhaust gases from all four gas turbines be used to

Outstanding geothermal research programs of German universities and state aided organizations (BGR, LBEG, GGA) are pointed out. Actual geothermal modeling programs based on the Finite-Element-Method or the Finite-Differences-Method as well as analytical programs are introduced. National and international geothermal projects supported by German universities and state aided organizations are described. Examples of supervised shallow and deep geothermal systems are given. Actually the Technical University Darmstadt is performing a research program supported by a national organization, the Ministry of Economics and Technology (BMWi). Main aim of this research program titled experimental investigation for the verification of a Finite-Element-Multiphase-Model is to analyze the subsoil as a three-phases-model with separated consideration of conduction, convection and advection and their subsequent interaction. The latest developments of numerical projects as well as the actual state of the before mentioned research program are pointed out in the paper.

    well as, system hardening backup centers. 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.

    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.

    A total of 3961 married couples from six major geographical areas representing the South Sinai governorates in Egypt were studied to assess the rate of consanguineous marriage. The population of six selected areas (St Catherines, Nuweiba, Abu Rudeis, Ras Sudr, El Tor and Abu Zenima) were subdivided into Bedouin, urban and mixed populations. A questionnaire-based interview was conducted showing that the consanguinity rate in this region is 37.5%, with the highest rate recorded in Abu Rudeis (52.3%) and lowest rate in Nuweiba (24.1%). Consanguinity was significantly higher among the Bedouin population compared with the urban population in Abu Rudeis, Ras Sudr, El Tor and Abu Zenima, while in St Catherines and Nuweiba there was no statistically significant difference. Among consanguineous couples, 5%, 60% and 35% were double first cousins, first cousins and second cousins respectively. The mean inbreeding coefficient α of the studied population was 0.01845.

    2007-01-01

    . In contrast to uropathogenic E coli (UPEC), which cause symptomatic urinary tract infection, asymptomatic bacteriuria (ABU) strains are associated with essentially symptom-free infections. 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....... The results support the notion of bacterial prophylaxis employing selected ABU strains to eliminate UPEC strains and other pathogens in patients prone to recalcitrant infections....

    Mosquitoes were surveyed over one year period in two localities in Cairo representing different levels of urban planning: El-Muqattam (planned) and Abu-Seir (unplanned). Culex pipiens, Cx. perexiguus, Cx. pusillus, Ochlerotatus caspius, Culiseta longiareolata and Anopheles multicolor were the collected species at both sites. Mosquitoes were more common in Abu-Seir than in El-Muqattam, with larvae of the filaria vector Cx. pipiens accounting for 81% and 52% of recorded individuals at these sites, respectively. Five types of the potential breeding habitats were detected of which, the cesspits (El-Muqattam) and drainage canals (Abu-Seir) were the most common while springs in El-Muqattam and drainage canals in Abu-Seir were the most productive types. Both Cx. pipiens and Cx. perexiguus bred year round with peaks of abundance coinciding with higher temperatures.

    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.

    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.

    Asymptomatic bacteriuria (ABU) is highly prevalent among elderly patients. It can be difficult to distinguish ABU from symptomatic urinary tract infection (UTI) in this population, which leads to unnecessary antibiotic treatment. Urinary heparin-binding protein (U-HBP) and urinary interleukin-6 (U-IL-6) have previously been studied as diagnostic markers for UTI. In this study, biomarkers were measured in the urine of 134 nursing home residents. The prevalence of ABU in this population, excluding patients with urinary catheter, was 32.8%. Levels of U-HBP and IL-6 were significantly lower among residents with ABU when compared to 49 patients with verified UTI. When previously defined cut-off limits were used, U-HBP had a high negative predictive value for UTI (93%), however, the specificity for differentiating patients with UTI and ABU was low. Discriminatory values were better for U-IL-6 with a sensitivity of 80% and specificity of 82% for the differentiation between the subgroup of pyelonephritis and ABU. Copyright © 2016 Elsevier Inc.

    the transport of heat across the planet) with a planetary orbit that evolves over time.The surface air temperature variation of a planet with orbital eccentricity of 0.283. The top panel shows the surface temperature when the planet is closest to the star in its orbit (periastron); the bottom when the planet is furthest from the star in its orbit (apoastron). [Way Georgakarakos 2017]The scientists, Michael Way (NASA Goddard and Uppsala University, Sweden) and Nikolaos Georgakarakos (New York University Abu Dhabi), focus in this study on the specific effects of a varying orbital eccentricity on an Earth-like planets climate, holding the planets axial tilt steady at Earths 23.5. They explore two scenarios: one in which the planets eccentricity evolves from 0 to 0.283 over 6500 years, and the other in which it evolves from 0 to 0.066 over 4500 years.Temperate OutcomesWay and Georgakarakos find that the planet with the more widely varying eccentricity has a greater increase rainfall and humidity as the planet approaches its host star in its orbit. Nonetheless, this effect is not enough to cause a runaway greenhouse scenario in which the planet becomes too warm for habitability. Similarly, the ocean ice fraction remains low enough even at apoastron in high-eccentricity scenarios for the planet to remain temperate.What does these results imply? Having a changing eccentricity caused by the gravitational pull of a nearby Jupiter-like neighbor may make a planets climate more variable, but not to the extent where the planet is no longer able to support life. Therefore, as we discover more such planets with current and upcoming exoplanet missions, we know that we neednt necessarily assume that they arent interest for habitability.CitationM. J.

    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.

    Full Text Available The proposed excerpt of theological work is the translation of the first chapter of «Qalandar-name», supplemented by comments. This is the first edition of chapter from the medieval theological work written in the Golden Horde during the active Islamization of its population, during the times of great Khans – Muhammad Uzbek and Janibek. Its author, Abu Bakr Qalandar, was a native of the city of Aksaray (in modern Turkey, Sufi, great scholar, imam of a mosque in the city of Stary Krym. «Qalandar-name» is an encyclopedic work on Islamic matters and Sufism that begins with a traditional intonation typical for the works of Muslim authors, especially for compilers of theological writings. In this chapter entitled «Tawhid» (monotheism, Abu Bakr Qalandar speaks about beautiful names of the Almighty, about his creative work (comparing it with the jewelry craftsmanship, about heaven and hell, a small (world of sagri and the highest (world of kibriya worlds. D. Shagivaleev who wrote commentaries on the first chapter, supplied the text with verses, to which, according to him, Abu Bakr made allusions. Analysis of the work of Abu Bakr Qalandar reveals that the author of this source was an educated man of his time. In this chapter, Abu Bakr reports about the basic concepts of Islam. The authors plan to publish subsequent chapters of this work in the next issues.

    Full Text Available Presented fragment is the next part of the translation of the medieval poetic text “Qalandar-name” written by Abu Bakr Qalandar, the Sufi scholar from Crimea. This Chapter is devoted to praises to four founders of schools of islamic law (madhhab: an-Numan Abu Hanifa, Mukhammad ash-Shafii, Ahmad ibn Hanbal and Malik ibn Anas. Incorrect order of praises of Imams (Ibn Malik is mentioned after other three imams shows that author of source belongs to Shafii madhhab. The author mentions the virtues of these imams, making the main emphasis on their knowledge. Reviewing their accomplishments author mentions “hundred usul”, “Mystery of Mohammads soul”, relating to Abu Hanifa. Imam Ibn Hanbal was notable for metapharistic translation of Quran and was called “Imam of faithfuls”(although he was a subject of inquisition by mutazilits for his views on creation of Quran. Malik Ibn Anas “cleaned the house from war and demons”, he was “mujtaheed”; here we give our own rendering of Abu Bakr Qalandar’s assumptions. In this chapter Abu Hanifa is resembled to “mind”, ash-Shafi to “soul”, Ibn Hanbal to “key to perception”, and imam Malik to “revelation” and transition from worldly to spiritual – paring the skin, that was written by many other sufi theorists. Also Abu Bakr acknowledges the legitimacy of this four ‘mazhabs’, writing that ‘all of us should follow this four imams and their students’, meaning branches (furu’, legal thesis of madhhabs, that were introduced later by their students.

    The clinical aspects of virulence genes of uropathogenic Escherichia coli (UPEC) are not fully understood. This study compared the presence of virulence genes in UPEC isolated from urinary tract infections (UTIs) and asymptomatic bacteriuria (ABU) in children. The study included children with UTI (n = 15) or ABU (n = 49) treated at Chung-Ang University Yongsan Hospital between 2010 and 2011. The strains were acquired from each urine sample collected, and 18 major virulence genes were detected by polymerase chain reaction. Antimicrobial susceptibility of all UPEC isolates was determined. Sixty-four E. coli strains were isolated from the urine samples. The most commonly identified virulence gene in both groups was fimH (100.0% in the UTI group and 95.9% in the ABU group). The UTI isolates showed a higher prevalence of papEF and fyuA, and a lower prevalence of feoB than ABU isolates (p < 0.01 for all). The profile of virulence gene, fimH(+)kpsMTII(+)feoB(+) also showed a significant difference between the two groups (p < 0.01). Isolates from ABU were more resistant to most antimicrobials tested. The presence of papEF, feoB, and fyuA also correlated with the antimicrobial susceptibility of UPEC. The virulence gene repertoire was different in the UPEC of UTI and ABU. The papEF, feoB, and fyuA genes showed meaningful differences between the two groups and may have an important role in the pathogenesis of overt UTI. Copyright © 2013. Published by Elsevier B.V.

    People with asymptomatic bacteriuria (ABU) are often unnecessarily treated with antibiotics risking adverse effects and antimicrobial resistance. We performed a systematic review to determine any benefits and harms of treating ABU in particular patient groups. Relevant databases were searched and eligible trials were assessed for risk-of-bias and Grading of Recommendations, Assessment, Development and Education quality. Where possible, a meta-analysis of extracted data was performed or a narrative synthesis of the evidence was presented. After screening 3626 articles, 50 studies involving 7088 patients were included. Overall, quality of evidence ranged from very low to low. There was no evidence of benefit for patients with no risk factors, patients with diabetes mellitus, postmenopausal women, elderly institutionalised patients, patients with renal transplants, or patients prior to joint replacement, and treatment was harmful for patients with recurrent urinary tract infection (UTI). Treatment of ABU resulted in a lower risk of postoperative UTI after transurethral resection surgery. In pregnant women, we found evidence that treatment of ABU decreased risk of symptomatic UTI, low birthweight, and preterm delivery. ABU should be treated prior to transurethral resection surgery. In addition, current evidence also suggests that ABU treatment is required in pregnant women, although the results of a recent trial have challenged this view. We reviewed available scientific studies to see if people with bacteria in their urine but without symptoms of urinary tract infection should be treated with antibiotics to eliminate bacteria. For most people, treatment was not beneficial and may be harmful. Antibiotic treatment did appear to benefit women in pregnancy and those about to undergo urological surgery.

    Before Charles Bell's eponymous account of facial palsy, physicians of the Graeco-Roman era had chronicled the condition. The later neglected accounts of the Persian physicians Abu al-Hasan Ali ibn Sahl Rabban al-Tabari and Abu Bakr Muhammad ibn Zakarīya Rāzi ("Rhazes") and Avicenna in the first millennium are presented here as major descriptive works preceding the later description by Stalpart van der Wiel in the seventeenth century and those of Friedreich and Bell at the end of the eighteenth and the beginning of the nineteenth centuries.

    The molecular mechanisms that define asymptomatic bacteriuria (ABU) Escherichia coli colonization of the human urinary tract remain to be properly elucidated. Here, we utilize ABU E. coli strain 83972 as a model to dissect the contribution of siderophores to iron acquisition, growth, fitness......, and colonization of the urinary tract. We show that E. coli 83972 produces enterobactin, salmochelin, aerobactin, and yersiniabactin and examine the role of these systems using mutants defective in siderophore biosynthesis and uptake. Enterobactin and aerobactin contributed most to total siderophore activity...
