Le rapport au savoir scientifique d'enseignantes et d'enseignants du primaire  

NASA Astrophysics Data System (ADS)

Nous avons procede a l'examen de problemes relatifs a l'education aux sciences via une approche a caractere epistemologique, contrairement a l'approche plus usuelle qui aborde les difficultes des apprenants a composer avec les connaissances dites scientifiques seulement d'un point de vue cognitif. La question de recherche que nous nous sommes posee a ete la suivante: Quel est le rapport au savoir scientifique d'enseignantes et d'enseignants du primaire? Pour repondre a cette question sur le plan methodologique, nous avons envisage l'etude du rapport au savoir scientifique d'enseignantes et d'enseignants dans un contexte relie a leur savoir et a leur expertise de tous les jours. Nos modalites de cueillette de donnees ont ete le recit ecrit et l'entrevue individuelle semi-structuree. Notre recherche a pris la forme d'une etude de cas multiples conduisant a l'etude des rapports epistemique, pratique et identitaire au savoir scientifique de dix enseignantes et enseignants d'ecoles populaires de Caracas, au Venezuela. Nos analyses nous ont amenee a affirmer que les sujets ont manifeste un rapport au savoir scientifique domine par la dependance et la soumission a l'egard des sciences ainsi que d'autres caracteristiques propres a une approche empirico-realiste. Cependant, dans un contexte relie a leur savoir-faire et a leur expertise, nous avons repere des traces de l'emergence d'une vision des sciences qui tient compte, entre autres, du caractere social de la production de ces dernieres, ce qui pourrait se qualifier comme faisant partie d'une tendance epistemologique du type socioconstructiviste. En plus, nos analyses nous amenent a suggerer que dans ce contexte les sujets auraient egalement initie une articulation entre leur savoir-faire et le savoir scientifique, ce qui les aurait amenes a vehiculer un rapport plus emancipatoire vis-a-vis les sciences. Cette articulation des savoirs permet egalement d'envisager des experiences educatives plus creatives, plus emancipatoires et plus en lien avec les visions contemporaines emergentes de la science, de son enseignement et de son apprentissage. Bien que de nombreuses recherches dans le domaine de l'education soulignent l'importance d'articuler les savoirs disciplinaires avec les savoirs d'experience, peu illustrent de maniere approfondie l'exercice de cette articulation. Notre recherche permet de penser a l'idee d'un rapport au savoir qui donne une veritable place a l'expertise publique des individus et non seulement a l'explication scientifique jugee la seule valable. Ainsi, au-dela des hierarchisations, chaque savoir aurait sa valeur et sa place, l'articulation des savoirs favorisant chez les sujets apprenants un plus grand interet pour l'apprentissage des sciences.

ASTER Suez Canal  

NASA Technical Reports Server (NTRS)

One of the most important waterways in the world, the Suez Canal runs north to south across the Isthmus of Suez in northeastern Egypt. This image of the canal covers an area 36 kilometers (22 miles) wide and 60 kilometers (47 miles) long in three bands of the reflected visible and infrared wavelength region. It shows the northern part of the canal, with the Mediterranean Sea just visible in the upper right corner. The Suez Canal connects the Mediterranean Sea with the Gulf of Suez, an arm of the Red Sea. The artificial canal provides an important shortcut for ships operating between both European and American ports and ports located in southern Asia, eastern Africa, and Oceania. With a length of about 195 kilometers (121 miles) and a minimum channel width of 60 meters (197 feet), the Suez Canal is able to accommodate ships as large as 150,000 tons fully loaded. Because no locks interrupt traffic on this sea level waterway, the transit time only averages about 15 hours. ASTER acquired this scene on May 19, 2000.

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

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

Longitudinal evolution of Suez rift structure, Egypt  

SciTech Connect

A three-dimensional study of the structure of the Suez Rift has been carried out using field and subsurface data in an attempt to determine the role of transverse faults and the longitudinal evolution of the rift. As in most intracontinental rifts, the structure of the Gulf of Suez area is governed by normal faults and tilted blocks, whose crests constitute the main target of exploratory wells. The fault pattern consists of two major sets of trends: (1) longitudinal faults parallel with the rift axis and created in an extensional regime, trending east-northeast-west-southwest, and (2) transverse faults with north-south to north-northeast-south-southwest dominant trend. The transverse faults are inherited passive discontinuities, whereas most of the longitudinal faults were created during the Neogene in a purely extensional regime. Both sets were simultaneously active, producing a zigzag pattern and rhombic-shaped blocks. The transverse faults can show horizontal strike-slip components and act as relays between major normal faults.

org.au Abstract—Alcohol-related problems (assaults, accidents and/or crimes) and alcohol abuse are recurrent societal problems leading to high social costs. Finding adapted policies to tackle this issue isn’t a trivial task due to the highly complex nature of alcohol consumption as many interrelated risk factors interact in a hardly predictable way. This paper describes an agentbased simulation model, called SimARC (Simulation of Alcohol-Related Consequences), aiming at exploring the complex interplay of these factors following a generative process whereby theory and model co-evolve within iterative loops. To explore the complexity of alcohol use and abuse, we need not only to include the aforementioned risk factors but also their evolution and highly dynamical interactions across scales. Therefore, our agent-based model aims to encapsulate several levels of reality. Considering an ontology as catalog of elements and relation amongst those elements, our ontologydriven behavioral model includes: neuro-biological responses to alcohol use (individual level), peer influence channeled through various social networks (meso-level) and societal responses to alcohol-related problems (meta-level). This ontological framework aims to establish a robust test-bed to analyze – in silico – the plausible consequences of various public policies related to alcohol abuse in public venues. After a brief review of the literature, we present SimARC’s core structure and preliminary results. Keywords-agent-based model; ontology; alcohol; social simulation; public health.

Residual Circulation in the Gulf of Suez, Egypt  

NASA Astrophysics Data System (ADS)

A three-dimensional non-linear hydrodynamical numerical model has been used to study the water movement in the shallow Gulf of Suez at the northern end of the Red Sea. The computational grid used to schematize the Gulf has a horizontal resolution of 3×3 km and levels at 5, 15, 30 and 60 m in the vertical. The simulations were carried out separately for tidal forcing and wind forcing. Further, in each case, stratified conditions were considered to represent the state of the Gulf during late summer periods. In the case of wind-induced circulations, a uniform wind speed of 5 m s -1was applied over the Gulf, blowing from NW, N and NE directions. The results suggest that the dynamics of the Gulf of Suez are governed by the interaction of wind and density forcing. Only occasionally, for instance in the vicinity of headlands and islands, tidal residuals are of similar importance. For the overall residual currents, it was found that the typical (quasi) baroclinic two-layered inverse-estuarine circulation observed in the Gulf of Suez can be produced under the combined action of M 2-tide and winds blowing steadily from the north-eastern direction. North-western and northern winds produced the reverse pattern.

Potential vulnerabilities of the Suez Canal to possible tsunami impacts are reviewed by reference to geological, historical, archaeoseismological, and anecdotal data. Tsunami catalogues and databases compiled by earlier researchers are perused to estimate potential return periods for tsunami events that could affect directly the Suez Canal and its closely associated operational infrastructures. Analysis of these various records indicates a centurial return period, or multiples thereof, for long-wave repetition that could generally affect the Nile Delta. It is estimated that tsunami waves 2 m high would have a breaking length about 5 km down Canal whereas a 10 m wave break would occur about 1 km into the Canal. Should a tsunami strike the eastern flanks of the Nile Delta, it would damage Egypt's maritime infrastructure and multi-national commercial vessels and military ships then using the Canal.

Stratigraphy and correlation of Belayim Cenomanian, Gulf of Suez, Egypt  

NASA Astrophysics Data System (ADS)

The Cenomanian rocks in the land and marine Belayim wells (Nos. 113-32, 113-M5, M1) in the eastern part of the Gulf of Suez are mainly clastics with few nonclastics. They have been referred to the Raha Formation and correlated with the Cenomanian in north Egypt. About 46 foraminiferal species could be identified. Species of Hedbergella, Thomasinella and Cribrostomoides are the most conspicous and form three definite and traceable biozones. The zonal as well as the recorded index species are useful in local, regional and intra-continental correlation.

Sea-level Variation Along the Suez Canal  

NASA Astrophysics Data System (ADS)

The variation of sea level at 11 stations distributed along the Suez Canal was studied during the period from 1980 to 1986. The ranges of variation in daily mean sea level at Port Said and Port Tawfik are about 60 and 120 cm, respectively. The minimum range of daily variation is at Kantara (47 cm). The fluctuations of the monthly mean sea level between the two ends of the Suez Canal vary from one season to another. From July to December, the sea level at Port Said is higher than that at Port Tawfik, with the maximum difference (10·5 cm) in September. During the rest of the year, the mean sea level at Port Tawfik is higher than that at Port Said, with the maximum difference (31·5 cm) in March. The long-term variations of the annual mean sea level at both Port Said and Port Tawfik for the period from 1923 to 1986 showed a positive trend. The sea level at Port Said increased by about 27·8 cm century -1while it increased by only 9·1 cm century -1at Port Tawfik. This indicates that the difference between sea level at Port Said and Port Tawfik has decreased with time.

Dimensions of Quality of Antenatal Care Sservice at Suez, Egypt  

PubMed Central

Introduction: The 5th millennium development goal aims at reducing maternal mortality by 75% by the year 2015. According to the World Health Organization, there was an estimated 358,000 maternal deaths globally in 2008. Developing countries accounted for 99% of these deaths of which three-fifths occurred in Sub-Saharan Africa. In primary health care (PHC), quality of antenatal care is fundamental and critically affects service continuity. Nevertheless, medical research ignores the issue and it is lacking scientific inquiry, particularly in Egypt. Aim of the Study: The aim of the following study is to assess the quality of antenatal care in urban Suez Governorate, Egypt. Materials and Methods: A cross-sectional primary health care center (PHCC) based study conducted at five PHCC in urban Suez, Egypt. The total sample size collected from clients, physicians and medical records. Parameters assessed auditing of medical records, assessing provider and pregnant women satisfaction. Results: Nearly 97% of respondents were satisfied about the quality of antenatal care, while provider's satisfaction was 61% and for file, auditing was 76.5 ± 5.6. Conclusion: The present study shows that client satisfaction, physicians’ satisfaction and auditing of medical record represent an idea about opportunities for improvement. PMID:25374861

Graben infilling in Gulf of Suez and Red Sea  

SciTech Connect

During the last 4 years, the French research group Genegass has completed geological and geophysical studies in the Red Sea and the Gulf of Suez. Neogene infilling of the basin is related with basement quality and volume of clastic supply, and inherited structural features are important to the development of Miocene rifting. The Neogene series may be divided into four major groups (Listed A-D), each limited by unconformities that seem to reflect the major stages of rifting. (A) The lowermost formations begin with a conglomerate and are followed by a variegated unit of sand and clay. In the Gulf of Suez, especially on the eastern bank, these formations are marine. Along the Red Sea, tilted blocks may be capped by stromatolites, and the valleys between them are the site of shale and evaporite sedimentation (lower Miocene). (B) The main extension phase results in an invasion of marine shales. The lower zones contain coarse clastics, and the high zones contain reefs and bioclastic limestone (late Burdigalian to early Serravallian). (C) The middle to late Miocene corresponds to a regional basinward tilting. Stromatolites coat the slopes, and conglomerate fans are found in the lower zones. Evaporite sedimentation dominates; anhydrite is found on the borders, and in the basin, thick halite is overlain by a clastic series. Basement shoulders are uplifted. (D) During the Pliocene and Pleistocene, the central part of the graben showed an important subsidence, and salt tectonism was active with diapirs and collapses.

A preliminary regional geothermal assessment of the Gulf of Suez, Egypt  

NASA Astrophysics Data System (ADS)

The tectonic setting of Egypt, in the northeastern corner of the African continent, suggests that it may possess significant geothermal resources, especially along its eastern margin. The most promising areas for geothermal development in the NW Red Sea-Gulf of Suez rift system are locations along the eastern shore of the Gulf of Suez that are characterized by surface thermal manifestations, including a cluster of hot springs with varied temperatures. The Gulf of Suez region is one of the most interesting geothermal areas in Egypt because of the high temperatures of its springs. Geothermal studies were performed based on bottom-hole temperature logs of 103 offshore oil wells in the Gulf of Suez. The eastern margin of the Gulf of Suez, especially in the vicinity of hot springs, is characterized by high temperature gradients and heat flow values of more than 100 mW/m 2. Geophysical studies, which characterized the gravity and aeromagnetic signatures of the Gulf of Suez, were used to investigate the origin of the high heat flow and to constrain the depths of the heat sources in the hottest areas. Based on these data, conceptual and numerical models of hydrothermal systems were developed of the Hammam Faraun and Hammam Musa hot springs, which are the hottest springs in Egypt. The modeling results show that the origin of the high heat flow is the uplifted basement rocks.

Extension and rifting: the Zeit region, Gulf of Suez  

NASA Astrophysics Data System (ADS)

A field analysis of faults and fractures in the Ras Gharib-Ras Gemsa region of the Gulf of Suez shows that the main Late Cenozoic extension occurred perpendicular to the rift axis. Three main types of dip-slip normal faults successively developed as the tilt of blocks bounded by antithetic normal faults increased. Determinations of the amount of extension from structural data are compatible with estimates made using subsidence data through a simplified model of lithospheric stretching. The uplift of rift shoulders is related in chronology and volume to the subsidence of the rift. The geometry of fault patterns and directions of extension suggests that the Late Cenozoic total movement corresponds to a counterclockwise rotation of 4-5° of Sinai relative to Africa, with a pole close to Cairo.

Extensional hard linkages, eastern Gulf of Suez, Egypt  

NASA Astrophysics Data System (ADS)

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

Miocene platform-margin reefs, Gulf of Suez, Egypt  

SciTech Connect

Jebel Abu Shaar is a completely dolomitized carbonate platform atop a crystalline basement horst on the western side of the Gulf of Suez. Margins of the platform, where not removed by synsedimentary faulting, are formed by well-developed coral reefs. The massive reef carbonates consistently illustrate two stages of growth: a basal paucispecific unit of branching coral bafflestone, mostly Stylophora and a thicker upper unit of diverse coral framestone, dominated by faviids. A deep-water, slope-parallel biostrome of ahermatypic corals, dominated by Dendrophyllia and containing numerous Balanophyllia and Madracis, is present 10 km north of Abu Shaar. Corals are well cemented by numerous rinds of marine cement which is overlain by geopetal internal sediment containing planktonic foraminifers and pteropods.

Examining the positive effects of rapport building: when and why does rapport building benefit adult eyewitness memory?  

PubMed

Most investigative interviewing protocols recommend building rapport with cooperative adult witnesses to increase the accuracy of their reports. Although a few recent studies support the benefits of rapport building on adult witness recall, no study has examined whether the timing of rapport in relation to post-event misinformation affects recall accuracy, and whether these effects are related to witness anxiety levels throughout the interview. The present study provided two hundred and thirty-three undergraduates with a videotaped mock crime followed by building high or low rapport either before or after they received post-event misinformation. All witnesses were then interviewed about the mock crime. Results indicated that high rapport before misinformation increased the amount of accurate information reported in a subsequent witness interview compared to low rapport. However, these recall benefits were not due to a reduction in anxiety. Theoretical implications and practical recommendations for police interviewing practices are discussed. PMID:24304449

Subsidence in the gulf of suez: implications for rifting and plate kinematics  

NASA Astrophysics Data System (ADS)

The Gulf of Suez is a Neogene rift which has evolved as one arm of the Sinai triple junction together with the Gulf of Aqaba and the Red Sea. Backstripping of well data in the central and southern Gulf of Suez shows three distinct phases of tectonic subsidence. During the initial stage of opening of the rift, the rate of subsidence was very low. In the late Burdigalian (Rudeis fm.) there is a rapid increase in subsidence. By the Middle Miocene, the subsidence had slowed again. Extending the backstripping to a two-dimensional cross-section of the Gulf of Suez allows better quantitative estimates of extension. Correcting for the large regional uplift ( 1100 m on the Egyptian side) is critical for obtaining accurate values for the extension. Uplift of the rift decreases the net tectonic subsidence by over one fourth, relative to that predicted by uniform extension. The total extension at the latitude of Gebel Zeit (28° N) is 30 km, which corresponds to 32-36 km at the triple junction. Approximately {1}/{3} to {1}/{2} of the extension occurred during the rapid subsidence of the second opening phase. Slower extension continued for the rest of the Miocene and throughout the Plio-Pleistocene. Stress directions calculated from microstructures exhibit several directional phases to the opening of the Gulf of Suez. These data, together with constraints from the other arms of the Sinai triple junction, can be combined into a scenario for the kinematic evolution of the region. At first, the Gulf of Suez is the northward continuation of the Red Sea, and both open at ? N30°. The first subsidence phase in the Gulf of Suez represents an initial startup of the rifting with very low amounts of extension. This geometry continued through the main phase of Suez extension. Subsequently, the Gulf of Aqaba formed as a strike-slip boundary. As the Arabia-Africa motion transferred to the Gulf of Aqaba, the direction of extension in the Gulf of Suez rotated clockwise towards perpendicular extension and slowed. The post-Miocene shift to oblique opening in the Gulf of Aqaba and the Dead Sea transform is the result of a minor change in the pole of opening. This change is below the current resolution of the data for the Gulf of Suez, which is probably opening at < 1 mm/ yr.

Neogene tectonic and stratigraphic events in the Gulf of Suez rift area, Egypt  

NASA Astrophysics Data System (ADS)

The Gulf of Suez Neogene (syn-rift) section contains at least five datable intra-basinal unconformities or stratigraphie hiatuses. These events and associated changes in sedimentary sequences seen in the basin can be related to changes in Suez rift subsidence, Miocene eustasy, and the tectonic effects of adjacent Red Sea and Dead Sea rifting. The first hiatus spans Oligocène to earliest Miocene time and separates syn-rift from pre-rift strata throughout the region. This erosional event resulted from regional emergence during the Oligocene and the initiation of Suez rifting. A second hiatus, from ~ 21-19 Ma, separates the poorly dated, shallow-marine Nukhul Formation of Aquitanian to early Burdigalian age from the overlying upper bathyal shales of the middle Burdigalian to Langhian (NN3-5) Rudeis Formation. This hiatus resulted from both a brief lowstand in early Burdigalian sea level and increased Suez rift-related tectonism. This event climaxed with the rapid tectonic subsidence that established deep-marine conditions by 19 Ma. A third major event occurs within the Rudeis at ~ 17 Ma (NN4, N7) and marks the initiation of uplift of I he rift shoulders and margins, and decelerated subsidence, or even minor uplift, in the axial trough. Hiatuses are seen over paleohighs e.g. tilted fault blocks, whereas coarse elastics are deposited in more basinal areas in submarine fans and as turbidites. A fourth unconformity, at ~ 14 Ma, separates the Middle Miocene Kareem Formation from overlying anhydrites and open marine shales of the Belayim Formation. Minor tectonic uplift throughout the Suez region resulted from this event, and a sill was established between the Mediterranean and Suez basins, allowing cyclic anhydrite-marl deposition from ~ 14 to 11 Ma. This "post-Kareem event" may be the sedimentary response to initiation of movement along the Dead Sea-Aqaba transform. A sharp drop in sea level at ~ 11 Ma restricted the Suez basin even more, and marked the initiation of massive halite precipitation in the central and southern Suez, well south of the sill area. A final major Neogene event occurs at the Miocene-Pliocene boundary, and is marked by a major unconformity caused by tectonic uplift. This tectonic pulse is related to initiation of Red Sea sea-floor spreading, and acceleration of sinistral motion along the Dead Sea-Aqaba transform at ~ 5 Ma. This event establishes the marine connection with the Red Sea and the sedimentary environments seen in the Gulf of Suez today.

Study of recent crustal kinematics along the Gulf of Suez, Egypt  

NASA Astrophysics Data System (ADS)

The subject of the research work is dealing with the use of GPS and seismological data for the investigation of recent crustal kinematics for geodynamical studies along the Gulf of Suez. The collaborative effort is extended to use GPS observations to assert the present tectonic features in the study region. The earthquake activity is relatively higher in the southern part of the Gulf and gradually decreasing northward. The high seismicity is mainly attributed to the presence of Sinai triple junction. GPS observations along Gulf of Suez controlled by the IGS permanent stations around the study region. On average, the survey data indicated the motion varies between 1 to 5mm/yr. The detected motions reflect the general trend movement of the Sinai Peninsula. Moreover, the deformation analysis indicates that the entire Gulf of Suez is predominated by extensional deformation in southern part. The obtained extensional deformation style is obviously decreased from south to the north that is consistent with earthquake distribution and regional tectonics models. Earthquake focal mechanisms in the Gulf of Suez have been predominated by normal faulting with left-lateral strike slip components that is consistent with regional tectonics. The extension axes derived from fault plane solutions are oriented in NNE-SSW direction in a good agreement with current stress field from borehole breakouts along the Gulf of Suez. Moreover, the recent GPS results are highly consistence with the obtained extension direction.

Tectonic evolution of the Gulf of Suez and the Gulf of Aqaba  

NASA Astrophysics Data System (ADS)

The tectonic evolution of the Gulfs of Suez and Aqaba can be determined using fault slip data. Early opening of the Suez rift in the lower Miocene resulted from NNE-SSW extension, oblique to the rift trend. Subsequent tectonic events began in the Late Burdigalian and were associated with ENE-WSW extension which determined the shape of the Suez rift. In the Gulf of Aqaba the movements are younger. The Late Miocene motion is associated with a strike-slip stress pattern (040° direction of extension associated with a 130° compression) which produced the left lateral motion between the Arabian plate and the Sinai peninsula. Since the end of the Miocene the faulting is the result of an E-W extension, which indicates a rotation of the regional stress pattern in the vicinity of the transform fault.

Fractured but not fractal: Fragmentation of the gulf of suez basement  

NASA Astrophysics Data System (ADS)

Recent geophysical studies revealed that the Palaeozoic basement of the Gulf of Suez consists of an enormous number of fault blocks whose network qualitavely resembles the contraction-crack polygons which can be found in nature in a wide variety of materials and on all scales (mud cracks, hardening concrete, age cracking in paintings, etc.). The fault network of the Gulf of Suez basement forms a rather uniformly spaced polygonal pattern, most of the blocks are four-sided, the lengths of block sides parallel with the Gulf of Suez axis are exponentially distributed. The power-law size distribution associated with the fractal (scale-free) fragmentation can be possibly ruled out. The paper calls attention to the necessity of calssifying the physical processes leading to fragmentations with exponential-, lognormal-, and power-law size distributions, respectively.

Spatial and temporal evolution of the Suez rift subsidence  

NASA Astrophysics Data System (ADS)

In an attempt to characterize the longitudinal evolution of the Suez rift, subsidence curves have been computed for 75 wells and 10 cross-sections distributed all along the rift. Tectonic and overall subsidence have been distinguished by means of the backstripping method showing the role of sedimentary loading effects. Regional maps and profiles of the tectonic subsidence indicate that, because of block tilting, transversal discrepancies are much more important than longitudinal ones. Along the axial zone no p3opagating phenomenon could be demonstrated, and the whole rift length is attained during the first 2 or 3 My as evidenced by the ubiquitous deposition of the basal Nukhul Fm of Aquitanian to Lower Burdigalian age. The tectonic subsidence history appears identical all along the axial trough during the first stages of rifting. It is characterized by two major events: (1) a rapid and strong subsidence between 20 and 15 My (Rudeis Fm), and (2) a tectonic quiescence between 15 and 5 My. Main longitudinal variations occur after 5 My, and during this period 3 zones may be distinguished: (1) a northern area (Darag Basin) where uplift is dominant, (2) a central part (most of the Gulf) with very low tectonic subsidence or quiescence and (3) a southern part (close to the Red Sea) where tectonic subsidence has restarted.

Miocene platform-margin reefs, Gulf of Suez, Egypt  

SciTech Connect

Jebel Abu Shaar is a completely dolomitized carbonate platform atop a crystalline basement horst on the western side of the Gulf of Suez. Margins of the platform, where not removed by synsedimentary faulting, are formed by well-developed coral reefs. The massive reef carbonates consistently illustrate two stages of growth: a basal paucispecific unit of branching coral bafflestone, mostly Stylophora and a thicker upper unit of diverse coral framestone, dominated by faviids. In the upper unit, the reef crest is massive columnar Porites and less common Caulastrea framestone. The back-reef is a framestone of diverse faviids, mainly Montastrea Favites, and Tarbellastrea, and interbedded reef-flat rhodolite rudstones. The back-reef and reef-flat facies grade onshelf into Stylophora bafflestone biostromers and faviid bioherms. The reef front is a shallow to intermediate depth zone of numerous and diverse faviids, dominated by Montastrea and Acanthastrea framestones, bioclastic sands, and hardgrounds. Deeper zones are mostly small Acanthastrea mounds or rhodolite/bivalve rudstones with scattered faviids and Acanthastrea. Synsedimentary lithification, internal sedimentationm, and bioerosion prevail throughout. A deep-water, slope-parallel biostrome of ahermatypic corals, dominated by Dendrophyllia and containing numerous Balanophyllia and Madracis, is present 10 km north of Abu Shaar. Corals are well cemented by numerous rinds of marine cement which is overlain by geopetal internal sediment containing planktonic foraminifers and pteropods.

The Suez Canal supports a diversified benthic algal flora; 133 species of benthic algae are now known from the Canal, as compared with only 24 in 1924. The vertical and horizontal distribution of algae is considered in relation to hydrographic factors. The algae display zonation and 3-4 algal belts are distinguished on the Canal banks on buoys and pier supports. Associated fauna include Balanus amphitrite and Brachidontes variabilis, together with various hydroids, sponges, ascidians, asteroids, ophiuroids and crustaceans. Merceriella enigmatica thrives well in brackish water habitats. The algal flora in the Bitter Lakes resembles that in the Red Sea. The number of Red Sea species decreases from Suez to Port Said in the littoral zone. On the other hand, bottom algae predominantly belong to Red Sea flora. Thirty of the species of algae found belong to the Indo-Pacific flora; half of these are new records to the Canal. Several of these Indo-Pacific algae have recently become established in the Eastern Mediterranean, whereas only two of the Mediterranean macro-algal flora (viz. Caulerpa prolifera and Halopteris scoparia) have been found in the Gulf of Suez. Two seagrasses, Halopia ovalis and Thalassia hemprichii, are recorded for the first time in the Canal. Only Halophila stipulacea has found its way into the Mediterranean via the Suez Canal, but none of the Mediterranean seagrasses is found either in the Canal or in the Red Sea.

Risk assessment during transport of radioactive materials through the Suez Canal  

NASA Astrophysics Data System (ADS)

In this paper a study for risk assessment of the impact of transporting radioactive materials, during the period 1986-1992, through the Suez Canal of Egypt is given. The code RADTRAN-IV was used for this study. The results of the code, for a normal case, show that the transportation of low activity materials such as uranium (U 3O 8) represent the main items that contribute significantly to the collective dose within the Suez Canal area (Port-Said, Ismailia and Suez). The values of the annual collective dose due to transportation of all radionuclide materials was found to be at a maximum in Suez town and is equal to 5.04 × 10 -8 Man-Sv for the whole populations. If we only consider the workder at the harbour (estimated to be 50 persons), the value of the annual collective dose is about 3.33 × 10 -4 Man-Sv. These values are less than the exemption value of 1 Man-Sv recommended by the IAEA. For the accident case, the following pathways are considered by the code: ground-shine, direct inhalation, inhalation of resuspended material and cloud-shine. The total values of the estimated risks for each radionuclide material are presented in table form and, in addition, health effects (genetic effects, GE, and latent cancer fatality), LCF) are discussed. The calculated values of the radiological risks are very low for the three towns, showing that no radiation-induced early deaths are to be expected.

Thermochronological investigation of the timing of rifting and rift segmentation in the Gulf of Suez, Egypt  

NASA Astrophysics Data System (ADS)

The Tertiary Gulf of Suez rift system is one of the best-studied continental rift systems and has inspired many fundamental geodynamic models for continental rifting. However, our limited knowledge of how extensional strain is spatially and temporally distributed has made it difficult to adequately evaluate models for the dynamic evolution of this rift. A critical aspect of constraining the evolution of rifting and rift segmentation in the Gulf of Suez involves acquiring reliable geochronological constraints on extensional faulting. This study has commenced a systematic investigation of the timing and spatial distribution of rifting, lateral rift segmentation, and rift localization within the Gulf of Suez, Egypt, employing apatite and zircon (U-Th)/He thermochronometry. (U-Th)/He thermochronometric analysis of sample transects from exhumed fault blocks within the rift integrated with structural data will allow us to directly determine the timing, distribution, and magnitude of extension. The onset of major rifting (~24-19 Ma) in the Gulf of Suez was marked by the development of crustal domino-style tilt blocks and syn-rift deposition of the late Oligocene non-marine Abu Zenima Fm and non-marine to restricted marine Nukhul Fm. Development of the Gulf of Aqaba-Dead Sea transform cut off the rift from the Red Sea rift at an early extensional stage. Apatite (AHe) and zircon (ZHe) (U- Th)/He data were collected from basement and pre-rift sedimentary sample transects from the central and southern Sinai Peninsula portion and the Gebel El Zeit area in the southern Gulf of Suez as well as from basement samples from selected drill cores off Gebel El Zeit. Preliminary data exhibit partially reset ages trending as old as ~70 Ma (AHe) and ~450 Ma (ZHe) from shallower structural levels (Proterozoic basement and Phanerozoic cover sequence). Structurally deeper samples yield abundant AHe ages of ~22-24 Ma, indicative of rapid cooling and exhumation during the early Miocene. More basin-ward AHe samples are as young as ~17 Ma, recording continued early to middle Miocene extension in the Gulf of Suez. Detailed thermochronometric dating in progress should yield a more complete picture of the temporal and spatial distribution of extensional faulting in the Gulf of Suez.

Women in parole: respect and rapport.  

PubMed

Although the number of females in law enforcement has increased in recent years, research suggests that the uniquely gendered contributions of females are minimized in favor of traditional modes of law enforcement, emphasizing physical presence, authoritative commands, and demonstrative control. This research examines women in parole, using in-depth interviews with a small convenience sample of female parole agents in California. Participants discussed their experiences as parole agents from the perspective of women in a predominantly male occupation. Overwhelmingly, they emphasized traditionally associated female traits of intuition, verbal communication, and relationships, over physical tactics. Participants emphasized the importance of building respect and rapport with parolees in multiple contexts, including in the parolees' homes, with the families of parolees, and at parolees' places of employment. Participants suggested that this approach ensures their personal safety and enhances parolee compliance, especially when considering their subjective account of experiences by male parole agents.

Determination and partitioning of metals in sediments along the Suez Canal by sequential extraction  

NASA Astrophysics Data System (ADS)

The application of sequential extraction technique was used to determine the chemical association of heavy metals in five different chemical phases (exchangeable F1, bound to carbonate F2, bound to Fe-Mn oxides F3, bound to organic matter F4 and residual F5) for sediment samples collected from the Suez Canal. From the obtained data, it can be seen that the surplus of metal contaminants introduced into the sediment from sources usually exists in relatively unstable chemical forms. A high proportion of the studied metals remained in the residual fraction. Most of remaining portion of metals was bound to ferromanganese oxides fraction. The low concentrations of metals in the exchangeable fraction indicated that the sediments of Suez Canal were relatively unpolluted.

Ascidian introductions through the Suez Canal: The case study of an Indo-Pacific species.  

PubMed

Although marine biological invasions via the Suez Canal have been extensively documented, little is known about the introduction of non-indigenous ascidians (Chordata, Ascidiacea), a group containing particularly aggressive invasive species. Here, we used a multidisciplinary approach to study the introduction of the ascidian Herdmania momus into the Mediterranean Sea. We reviewed its taxonomy and global distribution, and analyzed how genetic variation is partitioned between sides of the Suez Canal. The taxonomic revision showed that H. momus currently has a wide Indo-Pacific distribution. Genetic data indicated two well-differentiated colonization histories across the eastern Mediterranean. Our findings suggest that the range expansion of H. momus has been greatly facilitated by the combined effect of human-mediated transport and the species' ability to adapt to different environments. The integrative approach presented here is critical to attain a holistic understanding of marine biological invasions, especially when studying groups with a poorly resolved taxonomy. PMID:22857711

Uplift and extension at the Gulf of Suez: indications of induced mantle convection  

NASA Astrophysics Data System (ADS)

Reconstruction of tectonic movements since the initiation of the Gulf of Suez rift indicates that there has been 25-27 km of extension. The uplift bordering rift indicates that lithosphere heating greatly exceeds that producible by uniform lithosphere extension. I propose that small-scale convection induced by the rifting augments the heating introduced by extensional rifting and produces the broad uplifts flanking the rift.

Early rift structures: a comparison between the Gulf of Suez and the Gulf of Corinth  

NASA Astrophysics Data System (ADS)

Extensional processes may start for various raisons: thinning of the lithosphere by mantellic convection, far field stress, back arc phenomena and affect various crusts. The initial crust is some time rather homogeneous, as in the Gulf of Suez or, at the opposite highly heterogeneous, as in the Gulf of Corinth were the extension affects a former mountain belt. In the Gulf of Corinth, thrusts may be reactivated as decollement level whereas in the Gulf of Suez, except some thin and rather superficial shally beds, the unique decollement level is the brittle/ductile transition in the crust. These characteristics influence the development of the normal fault pattern and therefore the structural feature of the rift. We will document the difference between the two cited examples in term of spacing of the faults, block sizes and tilts. The major causes of the extension in both cases are also different: the Gulf of Suez is clearly related to a deep thermal anomaly, which induce a lithospheric and crustal thinning during the early Miocene (23 to 15 Myr). From 15myr, the extension has been stopped, except in the central southern part, and the main tectonic activity is the uplift of the shoulders and Miocene Gulf borders. At the opposite, the data on the Gulf of Corinth does not evidence any abnormal temperature field below the structure, but the Gulf of Corinth is located in a back-arc position and affected by the Westward propagation of the north Anatolian fault. These regional features induce very different subsidence and uplift histories of both zones. Subsidence, tilting and uplift, when existing, have been recorded by the syn-rift sediments. After a review of the data, we will discuss if the Gulf of Corinth, which is in an early stage of extension may or not represent the evolution of a “classical” rift as the Gulf of Suez, where the main phase of extension has been active.

Subsidence and origin of the Northern Red Sea and Gulf of Suez  

NASA Astrophysics Data System (ADS)

Sedimentary accumulation and subsidence rates in the northern Red Sea and Gulf of Suez can be explained by extreme separation in central areas of rift basins and only minor thinning and tilting of fault blocks around the margins. During the Oligocene, local relief permitted red clastic sediments to be shed from the present area of the Red Sea. Very high rates of crustal thinning in Late Oligocene or earliest Miocene in the central part of the Gulf of Suez and part of the Red Sea trough permitted rapid subsidence of an early Miocene erosion surface. Miocene and younger sediments are thick only in these central areas. Movement on the Dead Sea shear zone began at the same time as subsidence, effectively isolating the Gulf of Suez from further tectonism and allowing thermal subsidence to occur to the present. Extension in the northern Red Sea, south of the shear zone, has either been so extreme as to leave a crust of less than 10 km thickness or has been accomplished by injections of large quantities of mafic magma, forming a crust intermediate between continental and oceanic. All observations are consistent with models of rifting by pure stretching or by detachment faulting.

Possible axial extension in the Gulf of Suez rift (work hypothesis)  

NASA Astrophysics Data System (ADS)

The cross structure (SW-NE) of the Gulf of Suez is well documented through several studies on the rifting in the area, whereas less emphasis has been placed on the structural interpretation along the axial direction of the rift itself. The aeromagnetic data show the presence of two main trends: "clysmic" (N320°) and "cross" trend (N50°). The reflection seismic profiles covering the Gulf of Suez offshore area indicate an alternance of ranges and asymmetrical basins in the axial direction as well as across the rift. Well data demonstrate the presence of structural dips either in NW or SE directions both in the pre-rifting and syn-rifting sedimentary sequences deposited in these asymmetrical basins. In an overall rifting tectonic framework, to explain the structural configuration resulting from the above data along the axial direction would imply a possible extension parallel to the axis of the rifting itself. This extension component occurs along the pre-existing cross trend oblique to the rifting, while the Aqaba trend does not seem to play any role. The axial extension has been active since the time of early rifting and it appears to have been reactivated in more recent times. In a plate tectonic framework, the axial extension of the Gulf of Suez area implies a movement of the Sinai microplate oblique to the axis of the rifting.

Evaluation of poly-aromatic hydrocarbons (PAHs) in the aquatic species of Suez Gulf water along El-Sokhna area to the Suez refineries.  

PubMed

The Egyptian Red Sea environment especially along El-Sokhna area to the Suez refineries (Suez) is severely contaminated with organic compounds, as well as overfishing. This may be well contributory to recent serious declines in fish stocks. Fish embryos are also particularly vulnerable to oil exposure, even at extremely low concentrations of less than one part per billion. Consequently, even traces of oil pollution at levels often considered safe for wildlife can cause severe damage to fish. Sixteen polycyclic aromatic hydrocarbons (PAHs) were investigated in ten fish species of aquatic species by high performance liquid chromatography (HPLC). The compositions of PAHs determined in all samples were measured in order to use them as chemical markers for identifying different sources of PAH pollutants in the studied region. The total content of these16 PAHs ranged from 399.616 up to 67,631.779 ng/g wet weight. The data show that these values are considered to be alarmingly high enough to cause lethal toxicity effect by accumulation. All studied aquatic species samples are characterized by relatively high concentrations of the six-membered ring PAHs. The origin of PAHs in the collected samples is either petrogenic, biogenic, or mixed petrogenic and biogenic. PMID:24092254

Uplift and subsidence of the Suez rift: Constraints from fission-track analysis and sediment backstripping  

SciTech Connect

The Gulf of Suez is a Neogene rift that has evolved as one arm of the Sinai triple junction. The basement uplifts flanking the rift are larger than can be explained by uniform lithospheric extension. The timing of the regional heating required by the uplift has important implications for hydrocarbon maturation for the Gulf of Suez and rifts in general. The local geology indicates that the uplift did not predate rifting. Therefore, a regional subsidence and two-dimensional backstripping of the rift sediments were undertaken in conjunction with fission track analyses of the basement uplift. The initial rift deposits (Nukhul Formation) indicate slow extension during the earliest Miocene. The extension rate increased at the beginning of the deposition of the Rudeis Formation at approximately 19 Ma as the Gulf of Suez entered its main phase of rifting. By the end of the deposition of the Kareem Formation (approximately 14-15 Ma), most of the Africa-Arabia separation had transferred to the Gulf of Aqaba-Dead Sea transform. In order to determine the onset of the rift flank uplift relative to the rift history, 55 apatite fission track analyses were performed on samples from the basement of the eastern desert, on the western side of the rift. Apatite fission tracks record the thermal history of the samples for temperatures up to 125{degree}c. Apparent ages range from 382 to 11 Ma representing samples that have undergone various degrees of track annealing. Track length distributions clearly show the fading of tracks acquired prior to uplift in more deeply buried samples and the accumulation of long unannealed tracks subsequent to unroofing. The pattern of the track length vs. age distribution indicates that major uplift began simultaneously with the main phase of rifting at 19-20 Ma.

Pattern of Blood Stream Infections within Neonatal Intensive Care Unit, Suez Canal University Hospital, Ismailia, Egypt  

PubMed Central

Introduction. Blood stream infection (BSI) is a common problem of newborn in neonatal intensive care units (NICUs). Monitoring neonatal infections is increasingly regarded as an important contributor to safe and high-quality healthcare. It results in high mortality rate and serious complications. So, our aim was to determine the incidence and the pattern of BSIs in the NICU of Suez Canal University Hospital, Egypt, and to determine its impact on hospitalization, mortality, and morbidity. Methods. This study was a prospective one in which all neonates admitted to the NICUs in Suez Canal University hospital between January, 2013 and June 2013 were enrolled. Blood stream infections were monitored prospectively. The health care associated infection rate, mortality rate, causative organism, and risk factors were studied. Results. A total of 317 neonates were admitted to the NICU with a mortality rate of 36.0%. During this study period, 115/317 (36.3%) developed clinical signs of sepsis and were confirmed as BSIs by blood culture in only 90 neonates with 97 isolates. The total mean length of stay was significantly longer among infected than noninfected neonates (34.5 ± 18.3 and 10.8 ± 9.9 days, resp., P value < 0.001). The overall mortality rates among infected and noninfected neonates were 38.9% and 34.8%, respectively, with a significant difference. Klebsiella spp. were the most common pathogen (27.8%) followed by Pseudomonas (21.6%) and Staphylococcus aureus (15.4%). Conclusion. The rate of BSIs in NICU at Suez Canal University Hospital was relatively high with high mortality rate (36.0%). PMID:25389439

North to south longshore transport of well-sorted ooids in the northern part of the Gulf of Suez and of well-sorted quartz-feldspar particles, peloids and ooids in the southern part, results in the build up of hook-shaped spits. These spits protect coastal lagoons which become a trap for terrigenous mud. At first seasonally flooded sabkhas are formed, and eventually true supratidal sabkhas develop. Contemporaneously, spits are further developed seaward at the rate of several tens of meters during an active season.

Maturation, fecundity and seasonality of reproduction of two commercially valuable cuttlefish, Sepia pharaonis and S. dollfusi, in the Suez Canal  

Microsoft Academic Search

The cuttlefish Sepia pharaonis (maximum 250mm mantle length, ML) and S. dollfusi (maximum 150mm ML) are widely distributed in the Indo-Pacific from the Red Sea to Japan and Australia. They are the primary fishery in the Suez Canal and the most valuable commercial cephalopods in the northern Indian Ocean. However, their reproductive biology, essential for fishery management, is poorly known.

Since the opening of the Suez Canal, more than 120 Red Sea species colonized the eastern Mediterranean, whereas less than 10 Mediterranean species colonized the Red Sea. For most of the species involved in this colonization, the mode of dispersal from the source to the colonized area is through free-drifting propagules. In order to examine whether the current regime of

Subsurface structural mapping of Gebel El-Zeit area, Gulf of Suez, Egypt using aeromagnetic data  

NASA Astrophysics Data System (ADS)

The Gebel El-Zeit area is located on the western coast of the Gulf of Suez, Egypt. The areas in/and around the Gulf of Suez are generally important due to their hydrocarbon resources. In this study, we have applied gradient interpretation techniques (Euler deconvolution and analytic signal) to the aeromagnetic data of the Gebel El-Zeit area. The main objective of this study is to identify and delineate the possible subsurface structure of the area that may assist in locating new hydrocarbon prospects. Results of Euler method suggested that, on the eastern and western parts of the area, the basement could be observed on the ground (~50 m over the ground) and became more deeper on the central part to reach depth of 5 km (from the ground level). Results from the analytic signal method indicated that, the depth to the basement has an average value of 156 m on the eastern side and 758 m on the western side. Generally, the area is characterized by a graben structure bounded by major faults striking in the NW-SE direction.

Surface expression of an accommodation zone within the Gulf of Suez rift, Egypt  

NASA Astrophysics Data System (ADS)

The Gebel Gharamul region in the western Gulf of Suez offers an excellent outcrop example of the structural geometries associated with an accommodation zone termination. The surface expression of the accommodation zone is dominated by a basement promontory, which protrudes from the rift shoulder and underlies the junction of oblique ramps from two adjacent half-grabens, both of which face the Gulf of Suez. The southern half-graben represents the breakaway fault of the southwest-dipping tilt-block domain, and the northern half-graben represents the collapse of the upper plate above the northeast-dipping tilt-block domain. Basement and Nubian rocks in the hanging walls above the opposing low-angle detachments on either side of the accommodation zone are broken by gulf-parallel synthetic normal faults and orthogonal transfer faults, which act as block terminations and incrementally accommodate the large-scale rotation and displacement between adjacent blocks. The prerift and synrift stratigraphic succession is draped over this fault template, resulting in a complex and variable distribution of structures, the product of an inhomogeneous stratigraphic succession within an accommodation zone.

Marine Radioactivity Studies in the Suez Canal, Part I: Hydrodynamics and Transit Times  

NASA Astrophysics Data System (ADS)

This paper describes work carried out under the IAEA Project EGY/07/002 to study the dispersion of radioactive material in the Suez Canal. This effort is linked with the increased public concern about radiation safety through this important trade route. To follow the fate of radioactive wastes along this waterway, we had to solve the hydrodynamics of the water, governed mainly by tides, atmospheric forcing and the drift currents produced by horizontal salinity gradients and by differences in mean sea level (MSL) at the two entrances of the Canal. The hydrodynamics has been studied using both 1-D and 2-D modelling approaches, and a reasonable calibration has been possible from the data set prepared with the collaboration of the Suez Canal Authority. Dispersion of conservative pollutants has been preliminarily studied by using a 1-D-Gaussian approach. Thus, we are computing the path of the plumes and the time evolution of concentrations for different scenarios of discharges and under different seasonal conditions. The transit times can vary enormously during the year, ranging from a few days to several months, depending on the differences in MSL at the two entrances of the Canal.

Scale deposition in surface and subsurface production equipment in the Gulf of Suez  

SciTech Connect

Some of the Gulf of Suez oil fields (El-Morgan, July, and Shoab Ali) have been waterflooded with gulf seawater. Compatibility tests have indicated probable deposition of scale in surface and subsurface production equipment. This paper outlines the physical and theoretical prediction for downhole scale deposition in Gulf of Suez oil wells. It also describes field experience with CaSO/sub 4/ scale removal from the wells and their formations in view of field results of the implemented programs. Scale inhibition programs carried out to control downhole scale deposition by using the formation squeeze technique, along with the field results obtained from the squeezetreated wells, are described. A new improvement in the squeeze treatment technique has been introduced as highmolecular-weight polyacrylamide polymer solutions were incorporated to stage the scale inhibitor squeeze batch to prolong the treatment lifetime. Field results are presented, along with conclusions and recommendations that can be applied to similar problems, especially when wells of highly productive sandstone formations are to be inhibited.

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

SciTech Connect

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

Thermal history of the eastern margin of the Gulf of Suez, I. reconstruction from borehole temperature and organic maturity measurements  

NASA Astrophysics Data System (ADS)

The Gulf of Suez is a Tertiary continental rift associated with prominent flank uplift. Despite numerous studies which focused mainly on the western and central parts of the graben, the thermo-mechanics controlling the tectonic evolution of the Gulf of Suez is still enigmatic. We have integrated borehole temperatures and organic maturity measurements in the eastern margin of the Gulf of Suez, in order to study rift-related paleothermometry and the present-day thermal regime. The data obtained suggest that the present thermal regime represents the maximum heat flow and temperatures for the sedimentary section in the basin. Furthermore, lateral distributions of geothermal gradient and heat flow in the Gulf of Suez do not correlate, mainly because of extensive variability in lithology and thermal conductivity. Rift-related heat flow increases systematically and subparallel to the rift axis, from about 60 mW/m 2 in the Darag subbasin in the north to about 80 mW/m 2 in the Ras Garra area in the south. Both values are higher than 45 mW/m 2, the average heat flow assumed for the pre-rift stage and the characteristic level for the present-day heat flow away from the rift. The north to south increase in heat flow probably reflects the southward increase of extension as well as lateral transfer of heat flow from the Red Sea. This latter conclusion is supported by the fact that heat flow in the southern Gulf of Suez recorded by the paleothermometric reconstructions and borehole temperature data is somewhat higher than that estimated by model calculations for the extension derived from structural and subsidence reconstruction.

Geodynamic of the Gulf of Suez-Red Sea rifting and origin of within plate magmatism  

NASA Astrophysics Data System (ADS)

This study is an attempt to follow up the overall picture of the geologic processes of the "Wilson Cycle" in the Gulf of Suez Red Sea region. A plate-tectonic model is suggested covering the Pan-African collisional tectonics, post-Pan-African magmatism in space and time, and rifting stages in the Red Sea region. Field relations, petrography, and petrochemistry of the Tertiary basalt sheets of Abu Zenima area, Sinai, have been studied and correlated with some petrochemical data of Phanerozoic magmatic activities in the Red Sea region. The sequence of events of the tectonics and magmatic activities in the Gulf of Suez-Red Sea rift system may belong to six stages post Pan-African orogeny: (1) Paleozoic-Cretaceous continental bimodal alkaline magmatism resulting from the sinking of detached subducted oceanic plates, in the late stages of the Pan-African collisional tectonics. Consequently causing convection currents around them and partial melting of a deep undepleted mantle source; (2) Paleogene crustal doming and stretching as a result of asthenosphere upwelling activated by a long period of (? 300 m.y.) within plate alkaline magmatism; (3) Late Oligocene fissure-eruption of transitional (T-type MORBs) plateau basalts, dykes and sills on a regional scale. The transitional character of this basaltic activity is attributed to the soaking of the asthenosphere, during its slow upwelling, in the rising alkaline magmatism; (4) Early Miocene narrow long continental rifting in the Gulf of Suez-Red Sea region, probably due to a thermal contraction process resulting from the eruption of the Tertiary transitional, fissure-eruption basalts in large volumes from the upwelled asthenosphere; (5) Initiation of crustal separation of the very early stage of seafloor spreading, which is most probably characterized by mafic igneous rocks underplating of the crustal faulted blocks by dyke injection and related plutonic rocks; (6) Pliocene oceanic rifting and seafloor spreading generating N-type MORBs in the central parts of the Red Sea axial trough. In this stage, subsidence of the Red Sea passive marging could be due to a second stage of thermal contraction resulting from the extrusion and crystallization of asthenosphere material to construct the new oceanic crust.

Oligocene lacustrine tuff facies, Abu Treifeya, Cairo-Suez Road, Egypt  

NASA Astrophysics Data System (ADS)

Field investigations in the Abu Treifeya area, Cairo-Suez District, revealed the presence of Oligocene lacustrine volcaniclastic deposits of lacustrine sequences associated with an Oligocene rift regime. The present study represents a new record of lacustrine zeolite deposits associated with saponite clay minerals contained within reworked clastic vitric tuffs. The different lithofacies associations of these clastic sequences are identified and described: volcaniclastic sedimentary facies represent episodic volcaniclastic reworking, redistribution and redeposition in a lacustrine environment and these deposits are subdivided into proximal and medial facies. Zeolite and smectite minerals are mainly found as authigenic crystals formed in vugs or crusts due to the reaction of volcanic glasses with saline-alkaline water or as alteration products of feldspars. The presence of abundant smectite (saponite) may be attributed to a warm climate, with alternating humid and dry conditions characterised by the existence of kaolinite. Reddish iron-rich paleosols record periods of non-deposition intercalated with the volcaniclastic tuff sequence.

Sedimentological evidence for early Miocene fault reactivation in the Gulf of Suez  

NASA Astrophysics Data System (ADS)

The sedimentary response to early Miocene fault reactivation and marginal uplift in the Gulf of Suez is strikingly evident within the Gemsa half-graben. This mid-Rudeis event occurred in the late Burdigalian (16.5 Ma) approximately 8 m.y. after the onset of rifting. In outcrop, complicated lateral facies transitions reflect the change from a ramped margin to a structurally controlled depositional environment. Angular unconformities and truncation mark this event atop marginal tilt-block crests. Distal downlapping sequences are present in adjacent topographic lows that acted as sand depocenters. Channels draining the rift margins acted as point sources for basinward alluvial-fan development. Sand-ratio isopach maps reveal the presence of four active upper Rudeis Formation fan systems within the Gemsa half-graben.

2001 August earthquake swarm at Shadwan Island, Gulf of Suez, Egypt  

NASA Astrophysics Data System (ADS)

The earthquake swarm that struck Shadwan Island at the entrance of the Gulf of Suez in 2001 August included 408 events. Almost all of these events (94 per cent) were microearthquakes and only 6 per cent had small measurable magnitudes (5.0 > ML >= 3.0). Most of the earthquakes were weak and followed each other so closely in time that they could not be identified at more distant stations. The fault plane solutions of the strongest events of the swarm show almost identical focal mechanisms, predominately normal faulting with a significant sinistral strike-slip component for nodal planes trending NW-SE. A comparison with the mechanisms of the 1969 and 1972 events which took place 20 km north of the swarm epicentral region shows similarities in faulting type and orientation of nodal planes. The azimuths of T-axes determined from focal mechanisms in this study are oriented in the NNE-SSW direction. This direction is consistent with the present-day stress field derived from borehole breakouts in the southern Gulf of Suez and the last phase of stress field changes in the Late Pleistocene, as well as with recent GPS results. The source parameters of the largest (ML >= 3.0) events of the 2001 August Shadwan swarm have been estimated from the P-wave spectra of the Egyptian National Seismograph Network (ENSN). Averaging of the values obtained at different stations shows relatively similar source parameters, including a fault length of 0.65 <= L <= 2 km, a seismic moment of 7.1 × 1012 <= Mo <= 3.0 × 1014 N m and a stress drop of 0.4 <= ?? <= 10 bar.

Risk factors of falls among elderly living in Urban Suez - Egypt  

PubMed Central

Introduction Falling is one of the most common geriatric syndromes threatening the independence of older persons. Falls result from a complex and interactive mix of biological or medical, behavioral and environmental factors, many of which are preventable. Studying these diverse risk factors would aid early detection and management of them at the primary care level. Methods This is a cross sectional study about risk factors of falls was conducted to 340 elders in Urban Suez. Those are all patients over 60 who attended two family practice centers in Urban Suez. Results When asked about falling during the past 12 months, 205 elders recalled at least one incident of falling. Of them, 36% had their falls outdoors and 24% mentioned that stairs was the most prevalent site for indoor falls. Falls were also reported more among dependant than independent elderly. Using univariate regression analysis, almost all tested risk factors were significantly associated with falls in the studied population. These risk factors include: living alone, having chronic diseases, using medications, having a physical deficit, being in active, and having a high nutritional risk. However, the multivariate regression analysis proved that the strongest risk factors are low level of physical activity with OR 0.6 and P value 0.03, using a cane or walker (OR 1.69 and P value 0.001) and Impairment of daily living activities (OR 1.7 and P value 0.001). Conclusion Although falls is a serious problem among elderly with many consequences, it has many preventable risk factors. Health care providers should advice people to remain active and more research is needed in such an important area of Family Practice. PMID:23504298

Sedimentology and significance of an early syn-rift paleovalley, Wadi Tayiba, Suez Rift, Egypt  

NASA Astrophysics Data System (ADS)

Wadi Tayiba is located along the western margin of the Hammam Faraun fault block, western Sinai, Egypt and is generally thought to contain exposures of the 'type-section' for late pre-rift to early syn-rift stratigraphy associated with the Oligo-Miocene Suez Rift. Previous studies have suggested a complex vertical succession of sedimentary facies characterise the late pre-rift to early syn-rift and imply major and abrupt variations in relative sea-level during this time. Detailed sedimentological and stratigraphic analysis of the Wadi Tayiba type-section presented in this study identifies not only a far simpler vertical facies succession than previously suggested but also the development of a major paleovalley system at the base of the early syn-rift succession. It is suggested that this subtle but significant feature is the cause of the complex vertical facies succession previously interpreted. It is concluded that continuous marine sedimentation and only moderate amplitude variations in relative sea-level occurred during the Eocene to Early Oligocene within at least this part of the Suez Rift. A major relative sea-level fall occurred during the middle Oligocene and a regionally developed erosional surface associated with this event marks the contact between late pre-rift and early syn-rift strata. The results of this study have major implications for sub-regional correlations of late pre-rift to early syn-rift stratigraphic units and resultant palaeogeographic reconstructions of the late pre-rift to early syn-rift period.

Tectonic Analysis of Esh El-Mallaha Area, Gulf of Suez Using Euler Deconvolution for Aeromagnetic Data  

NASA Astrophysics Data System (ADS)

Esh El-Mallaha area is located on the western coast of the Gulf of Suez which is considered the main source of hydrocarbon resources in Egypt. The main exploration problem of the Gulf of Suez (and areas around) is the existence of the Pre-Miocene salt that masks the seismic energy and as a result, seismic method is not usually able to provide information about the subsurface structure. A solution may be existed using potential field methods such as magnetic which is highly sensitive to basement and not affected by salt. Herein, aeromagnetic data over Esh El-Mallaha area have been interpreted to provide a new look on the subsurface structure and tectonics of the area. This interpretation includes the application of Euler method which has been considered as a sufficient tool in magnetic interpretation. Comparing the results of Euler method with the available geologic data (wells, geologic maps), Euler method facilitates in identification of new faults as well as mapping of known faults from geologic information. Generally, the area is characterized by two basins structure trending in the NW-SE (parallel to the Gulf of Suez) direction. These two basins are separated by a high topographic feature (Esh El-Mallaha range) and bounded by faults of most probably normal type.

Controls on erosional retreat of the uplifted rift flanks at the Gulf of Suez and northern Red Sea  

NASA Astrophysics Data System (ADS)

The Gulf of Suez and Red Sea rifts are currently bordered by large asymmetric uplifts that are undergoing erosion. We find that the amount and timing of erosion vary systematically along the strike of the margin and have been controlled by variations in the prerift stratigraphy. The prerift strata are composed of cliff-forming Eocene-Cretaceous carbonates overlying the easily eroded Cretacous-Cambrian "Nubian" sandstone. This lithologic succession promotes scarp retreat of the sedimentary section, followed by dissection of the underlying basement. The prerift section thins from over 2000 m at the northern end of the rift to less than 400 m at its junction with the Red Sea. Thus, at the northern part of the Gulf of Suez, the Nubian sandstone is minimally exposed, and the carbonates form a scarp at the rift border fault. Farther south, undercutting of the carbonates by erosion of the sandstone has resulted in scarp retreat. The escarpment cuts diagonally away from the border fault and is over 100 km inland from the border fault at the southernmost Gulf of Suez. The amount of retreat varies inversely with the sediment thickness. Exposure and erosion of basement are initiated by the retreat of the escarpment, and the depth of erosion, as indicated by fission track ages, increases with distance from the escarpment. These observations are explained by a model in which erosion along the Gulf of Suez is initiated as rift flank uplift becomes sufficiently large to expose the friable sandstones. Undercutting of the escarpment and exhumation of basement has been propagating northward and westward for at least 20 m.y. The average rate of scarp retreat has been 6 km/m.y. and the along-strike propagation of the erosion has been 12 km/m.y. The diachronous erosion of the the rift flanks at the Gulf of Suez highlights the importance of distinguishing between the timing of uplift and of erosion. Both thermochronometric and stratigraphic data primarily indicate the timing of erosion, which may differ significantly from the timing of the uplift that initiates it. They must be interpreted carefully to avoid erroneous conclusions about rift tectonics.

Oil-oil and oil-source rock correlations in Gulf of Suez, Egypt  

SciTech Connect

According to published geological studies, there are two theories regarding the origin of petroleum in the Gulf of Suez area. One theory advocates that the majority of the oil accumulations in this region originate from two different source rocks: Eocene limestones and Miocene marls. The other theory states that only Miocene marls and shales of the Gharandal and Ras Mallah groups are the source rocks. The present study is a geochemical evaluation of Eocene limstones as potential source rocks. Samples were analyzed for their petroporphyrin types and distributions using established analytical techniques that included uv/vis, mass spectrometry, and high pressure liquid chromatography (HPLC). These techniques permitted the determination of several petroporphyrin parameters such as yield, distribution, and the ratios of nickel to vanadyl complexes and of DPEP to etio types. These geochemical parameters were then employed for oil-oil and oil-source rock correlations of the samples analyzed. In general, the oils had higher porphyrin contents, higher vanadyl to nickel porphyrins ratios, and lower DPEP to etio ratios compared to the shales. Most importantly, however, the porphyrin distribution (HPLC fingerprints) for the oils were significantly different from those of the shales. The shale samples showed three different fingerprints, one of which is uncommon of petroporphyrins found in petroleum and related bitumens. Among the oils, two different fingerprints were observed, regardless of their geological age. Although these observations suggest more than one source for the oils, they could not corroborate the the assumption that the Eocene formation is a potential source rock.

Cataclastic slip band distribution in normal fault damage zones, Nubian sandstones, Suez rift  

NASA Astrophysics Data System (ADS)

In this paper, we characterize the geometry of damage zones that form around the main slip planes of normal faults. Specifically, we examine five faults of varying throws that affect the Nubian sandstones along the Suez rift. To quantify the density of cataclastic slip bands (CSBs) associated with the main slip plane, we recorded the position of all visible CSBs along a scan line perpendicular to the fault through to the damage zone. For each outcrop the scan line record is ~30 m long. Resulting density diagrams display concentrations of CSBs and clearly indicate a widening of the damage zone with increasing throw. A correlation integral was calculated for each CSB population in order to analyze both the scaling property of the density distribution and potential correlation lengths. From centimeter to meter scale, representing 2 orders of magnitude, the correlation integral appears adequately modeled by a power law, emphasizing the fractal property for the CSB distribution. For the five faults the calculated correlation dimension is constant within its error of determination, Dc = 0.87 +/- 0.05. The validity range of the fractal nature was derived from an adequate normalization of the correlation integral and from a comparison with synthetic fractal fracture networks. It appears that a finite correlation length corresponding to the damage zone width is detectable for meter-scale throws; for larger throws the correlation length is not detectable within the sampling domain.

Facies and sequence stratigraphy of some Miocene sediments in the Cairo-Suez District, Egypt  

NASA Astrophysics Data System (ADS)

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

Tectonic and sedimentary evolution of the Gulf of Suez and the northwestern Red Sea  

NASA Astrophysics Data System (ADS)

The structural pattern of the Gulf of Suez and Red Sea Rift is inherited from the basement tectonics. N140 faults (clysmic direction), parallel to the regional elongation of the rift, are associated with submeridian (Aqaba direction) and sub-E-W faults (Duwi direction) that also play an important role in the rifting processes. The pre-rift sedimentary cover includes Cretaceous and Eocene platform deposits. It was slightly deformed prior to rifting. The syn-rift sedimentary sequence comprises four major units (groups A to D) delimited by unconformities: Group A (Oligocene to Early Burdigalian), continental to restricted subaquatic deposits; Group B (Burdigalian to Middle Miocene), open marine sediments; Group C (Middle to Upper? Miocene), major evaporitic episode; and Group D (Plio-Pleistocene) which returns to an open marine environment. Four majors stages of structuration are recorded: an initial stage of compressive deformation (direction of shortening close to NW-SE) characterized by strike-slip movements and associated drag folds (early Group A); a tilted block stage (late Group A) corresponding to the period of highest extensional rate; a horst and graben stage (Group B) resulting in the cutting out of the tilted blocks by numerous synthetic faults; Group B corresponds to the period of highest subsidence rate when a flexuration stage of the margin, expressed by a centripetal evolution of the subsidence, is associated with major periferal uplift.

Listeria spp. in the coastal environment of the Aqaba Gulf, Suez Gulf and the Red Sea.  

PubMed

Listeria monocytogenes is an important pathogen which causes an infection called listeriosis. Because of the high mortality rate (~30%) associated with listeriosis, and the widespread nature of the organism, it is a major concern for food and water microbiologists since it has been isolated from various types of foods, including seafood, as well as from the aqueous environment. To investigate the prevalence of this pathogen in the Aqaba Gulf (12 sites), Suez Gulf (14 sites) and Red Sea (14 sites), 200 water samples (collected during five sampling cruises in 2004), 40 fresh fish samples and 15 shellfish samples were analysed using the enrichment procedure and selective agar medium. All water samples were also examined for the presence Listeria innocua which was the most common of the Listeria spp. isolated, followed by L. monocytogenes, with a low incidence of the other species. During the whole year, the percentage of Listeria spp. and L. monocytogenes in 200 water samples was 20.5% (41 samples) and 13% (26 samples) respectively. In fresh fish (40 samples) it was 37% (15 samples) and 17.3% (7 samples) and in shellfish (15 samples) 53% (8 samples) and 33% (5 samples) respectively. In water samples, there was an association between the faecal contamination parameters and the presence of the pathogen; however, water salinity, temperature, dissolved oxygen and pH did not influence the occurrence of this bacterium. These results may help in the water-quality evaluation of the coastal environments of these regions. PMID:16371177

Subsurface Structural Imaging Of Esh El Mallaha Area, Gulf Of Suez, Egypt Using Aeromagnetic Data  

NASA Astrophysics Data System (ADS)

This paper presents a case study on the subsurface structural imaging of Esh El Mallaha area. Esh EL Mallaha area is located on the western flank of the Gulf of Suez and it has a great importance due to its hydrocarbon resources. In 1994 the area was covered by aeromagnetic survey conducted by Aero Service Division, Western Geophysical Company of America. The main object of this work to delineate the subsurface structural framework of the area that may assist in hydrocarbon exploration. A 3D analytic signal technique was applied to the aeromagnetic data. One of the most advantages of the analytic signal is that it produces a maximum value over a 2D magnetic source and as a result it enables more accurate location of the magnetic sources. It is also straight forward to determine the depth to the magnetic contacts using a simple formula derived from the analytic signal. Generally, Esh EL Mallaha area is characterized by two basinal structures taking the direction of the NW-SE parallel to the Red Sea rift. Those two basins are separated by long dike igneous rocks bounded by two major faults and taking the direction of NW-SE.

Physico-chemical conditions for plankton in Lake Timsah, a saline lake on the Suez Canal  

NASA Astrophysics Data System (ADS)

Lake Timsah receives high salinity water from the Suez Canal, mainly from the south, and freshwater from a Nile canal and other sources, producing a salinity stratification with surface salinities of 20-40‰ and over 40‰ in deeper water. Water temperature at a depth of 50-70 cm fell to below 20 °C in winter and rose to above 30 °C in summer; oxygen concentration at the same depth ranged between 6-10 mg l -1 and the pH was 8·1-8·3, and at mid-day this water was supersaturated with oxygen through 6-8 months of the year. The main chemical nutrients reached their highest levels in winter (December-February) and their lowest levels in summer (May-August), silicate varying between 1-7 ? M, phosphate between 0·1 and 0·8 ? M and nitrate between 4-10 ? M; nitrite varied in a more complex manner, usually between 0·25 and 0·4 ? M. The atomic ratio of N/P was generally well above the Redfield ratio level, except for a few months in midwinter. These nutrient concentrations are high in comparison with those of unpolluted seas of the region, but are typical of the more eutrophic coastal waters in most parts of the world.

Timing of structural development of oil traps in Gulf of Suez, Egypt  

SciTech Connect

To date, more than 40 oil fields with an estimated 25billion bbl of oil in place have been discovered in the Gulf of Suez, Egypt. These oil accumulations are present both in the pre-graben and graben-fill cycles which are separated by Oligocene tectonic phase, hitherto considered to be responsible for differentiation and formation of oil traps. In the present study, the structural development of many oil traps is related to intra-Rudeis tectonic phase of late early Miocene age. Presence of an a

Dinoflagellates from the Miocene Rudeis and Kareem formations borehole GS-78-1, Gulf of Suez, Egypt  

NASA Astrophysics Data System (ADS)

The Miocene Rudeis and the Kareem formations encountered in the Neogene part of the GS-78-1 borehole, Gulf of Suez produced diverse assemblages of dinoflagellate cysts, spores and pollen. The Early Miocene (Burdigalian) age assigned to the Rudeis Formation and the Early-?Middle Miocene (Langhian-Serravallian) age postulated for the Kareem formation is based on the presence of dinoflagellate cysts. These offer a good basis for biostratigraphic correlation of the Miocene deposits in the Gulf of Suez with those in the Nile Delta and Sinai in Egypt, and also with those present in key sections from the Mediterranean, the Canadian offshore sequences, Northwest Europe and from the North Atlantic. The terrestrial palynoflora (spores and pollen) affords no really precise, independent testimony as to the age of the samples, apart from being generally indicative of a Neogene age, in accord with the established gross age of the sediments, derived mainly from planktonic forams, calcareous nannoplankton and dinoflagellate cysts. The Rudeis Formation was deposited in a relatively deep water environment, based on the abundance fluctuations in miospores and dinoflagellates. However, the miospores recovered from the Rudeis Formation give an equivocal signal with respect to depositional environment. Such observed incursions of terrestrial elements in the Rudeis Formation could indicate that they might have been carried about within the basin of deposition by the waters of the Mediterranean Sea, or that they were displaced into a deep water setting. The overlying Kareem Formation was identified as an outer continental shelf deposit to upper bathyal (distal) environment because it contains a higher percentage of marine dinoflagellate cysts in most investigated samples, except in its uppermost part which shows the lowest percentage of marine forms. These include Spiniferites ramosus, S. pseudofurcatus, Operculodinium centrocarpum, Polysphaeridium zoharyi, Systematophora placacantha and Lingulodinium machaerophorum. The consistent presence of P. zoharyi in the Kareem Formation indicates that the Gulf of Suez was at times in the tropical to subtropical belt during the Early-?Middle Miocene age.

Seismic study of the crust of the northern Red Sea and Gulf of Suez  

NASA Astrophysics Data System (ADS)

We report the results of fifteen Expanding Spread Profiles (ESP's), and a seismic wide angle reflection-refraction Une, performed during March-April 1986, in the Gulf of Suez and the Egyptian part of the northern Red Sea area (north of 25°N). Four 16.4 air guns were used as a sound source on board R.V. "Le Suroit" and a 96-channel 2.4-km long streamer was towed by a supply vessel, the "Whity Tide". Most of the profiles show good crustal reflection and refraction arrivals and often good Moho arrivals obtained for a distance of 80 to 100 km. We present the results of X- T and ?- p analysis, obtained by a velocity inversion performed in the ?- p plane and by ray-tracing modeling of both the ?- p and the X- T sections. The velocity models are computed for planar and linear gradient velocity layers. The northernmost part of the Red Sea appears to be characterized by a continental type crust, extremely thinned (? ? 4), lying at a mean depth of 7-8 km, whereas the Moho is at a mean 14-15 km depth. The southern part shows a seismic velocity structure of an oceanic type, except in the 40 km closest to the coastline. In both parts, seismic waves progressively get more attenuated with distance from the shore to the axial zone, which is presently tectonically active. The difference between the northern continental and southern oceanic zone is related to the termination of the Levant Fault. The northern continental area appears to represent the termination of the Levant Fault as a zone of distributed deformation.

Fault-block tilting: the Gebel Zeit example, Gulf of Suez  

NASA Astrophysics Data System (ADS)

The Gebel Zeit consists of the eroded crest of a tilted block in the southern part of the Suez rift. The Zeit block displays a typical asymmetrical geometry: it is bordered to the east by a 35-45° E-dipping normal fault with kilometric throw and has a 30° SW-dipping homoclinal flank. Part of the pre-rift sedimentary sequence has been preserved on this flank and is unconformably covered by Upper Burdigalian (NN4) Globigerina marls. In the southern part of the block crest, the complete pre-rift series has been eroded and evaporites of Langhian age (NN5) rest directly on the Precambrian basement. Field evidence indicates alternations from erosion to sedimentation at the crest of the Zeit block. In an attempt to characterize its tilting, subsidence curves were computed along a cross-section with the backstripping method. Results indicate three stages in the evolution of the block: (1) a rapid subsidence between 22 and 16 My; (2) a pause between 16 and 10 My; and (3) a slow subsidence until present time. During the tectonic quiescence, the sedimentary loading effect alone produced an increase of 8° in the tilt angle. A simple kinematic model of tilting along a circular fault is proposed to quantify the Zeit rotation. Depth of the brittle-ductile transition is estimated at 10 km to explain the tilting. Strong driving of the tilting by the listric fault induces conjugate movements between the crest and trough of the block and explains the discrepancy between the Zeit and regional tectonic subsidence.

Preliminary seismicity and focal mechanisms in the southern Gulf of Suez: August 1994 through December 1997  

NASA Astrophysics Data System (ADS)

This paper shows an evaluation of the seismic activity in the entrance of the Gulf of Suez using the data recorded by Hurghada Seismological Network (HSN), in the period between August 1994 and December 1997 and represents an extension for the work published by the previous investigators. Hypocentral locations were determined for 180 earthquakes (duration magnitude ranged between 1.6 and 4.3) selected from 300 recorded events. All these events are located with epicentral error and depth error of less than 2 km. The spatial distribution of these earthquakes indicates the presence of three active areas. These are Shadwan Island, Gubal Island and the area adjacent to the southern tip of Sinai Peninsula. Such pattern of activity implies a localization of stress below these areas. The concentration of the stress field in these areas may have been strongly controlled by ductile necking and or intrusion. Composite fault plane solutions were also constructed for each of the three active areas. The data for each area was divided into groups, according to geographical position and uniformity of polarity data. In Shadwan Island, the composite fault plane solution of 15 events shows almost pure dip-slip motion. The composite fault plane solutions in Gubal Island and the area adjacent to the southern tip of Sinai Peninsula indicate a mixed regime of both strike-slip and extensional faulting mechanisms. The stress regime obtained from the fault plane solutions in this study is predominantly NNE-SSW tensional stress field. This result is consistent with the present day stress field, which has a 010° ± 18° orientation. The overall results are correlated with the structural setting of the area known from other sources.

Vertical Distribution of Seismic Anisotropy Beneath the Western Flank of the Gulf of Suez.  

NASA Astrophysics Data System (ADS)

We investigate the vertical distribution of seismic anisotropy beneath the site on the western flank of the Gulf of Suez. The area was affected by rifting during early stages of the Arabian-Nubian Shield breakup, but became quiescent at ˜15 Ma when the locus of rifting shifted to the Gulf of Aqaba. We use two complimentary techniques sensitive to seismic anisotropy: birefringence in teleseismic SKS phases, and receiver function analysis focused on directional and epicentral systematics of SH-polarized converted waves. While the first method provides an integral measure of anisotropic properties, the second is sensitive to abrupt changes in them. Data used in the analysis were collected by the station KEG (Kottamya, Egypt) operated as a part of the MEDNET project from 1990 through 1999. Measurements of shear wave splitting yield fast directions in the range of 20° -40° NE for the majority of observed backazimuths. A significant minority of observations, clustered around backazimuths of 85° -90° and 260° -270° , displays more northerly fast directions. Such systematic variations in the value of fast direction are expected if the anisotropic fabric varies with depth. Indeed, numerous phases indicative of anisotropy are evident in the receiver functions. Most conspicuously, the crust-mantle transition displays characteristic traits of anisotropy, with transversely polarized pulses of opposite polarity observed from the northeast and from the west. The likely orientation of the symmetry axis for these phases is within 15° of south. Additionally, a shallow converted phase (2 s delay) exhibits polarity changes near backazimuths of 60° NE and 310° NW, while a deeper feature ( ˜12 s delay) seen from the west change polarity around backazimuth of 300° . We construct a vertical profile of seismic properties (velocity and anisotropy) beneath station KEG by jointly modeling the receiver functions and the pattern of fast shear wave directions. Inferred depths, types and orientations of anisotropy-inducing fabrics are interpreted in the context of the tectonic history of the region.

Tectonic control on carbonate platform facies distribution and sequence development: Miocene, Gulf of Suez  

NASA Astrophysics Data System (ADS)

Mid-Miocene deposition in the southwestern Gulf of Suez was governed by an extensional fault-block topography. Shallow marine carbonates and clastics were deposited around the exposed block crests and in marginal half-grabens of the rift, while central troughs were filled by slope aprons and turbiditic and pelagic mudstones. Fan deltas developed at points along the fault-block escarpments. Syn-rift platform carbonates from one block crest, Esh el Mellaha, are described here. The platform evolved in three stages, generating three sedimentary sequences. Sequences 1 and 2 were separated by boundary fault reactivation, sequences 2 and 3 by sea-level drawdown, exposure and karstification. The sediments comprise six lithofacies associations (LA 1- 6). Reef (LA 1), fore-reef (LA 2) and back-reef/embayment (LA 3) sediments form a small reef-rimmed platform in sequence 1 at the southern end of the block. Fringing reefs and reef-lagoon systems also developed along the footwall escarpment and on fan deltas which bridged the block-bounding fault. Fringing reefs in sequence 2 generated a carbonate talus veneer (LA 4) along the whole 80 km length of the Esh el Mellaha fault scarp. Carbonate slope and reefal sediments preserved on the footwall exhibit abundant evidence of syndepositional fault movements, with truncation of escarpment-fringing sequences and repeated generation of reefal wedges. Minor drowning at the sequence 1-2 boundary caused deepening of lagoons, progradation of leeward reefal margins (with lagoonal patch-reef development), and back-stepping and vertical accretion of the reefal rim. Platform development was followed by algal-laminated dolomitic sediments (LA 5) in the area of the old platform interior (sequence 3). Much of the Esh el Mellaha ridge remained exposed during platform growth and shed coarse alluvial clastic sediments (LA 6) into the peripheral marine environments. The relationships demonstrated between Miocene sedimentation and structural setting have parallels in the modern environments of the Zeit Bay area.

GC estimation of organic hydrocarbons that threaten shallow Quaternary sandy aquifer Northwestern Gulf of Suez, Egypt.  

PubMed

Soil and groundwater contamination is one of the important environmental problems at petroleum-related sites, which causes critical environmental and health defects. Severe petroleum hydrocarbon contamination from coastal refinery plant was detected in a shallow Quaternary sandy aquifer is bordered by Gulf in the Northwestern Gulf of Suez, Egypt. The overall objective of this investigation is to estimate the organic hydrocarbons in shallow sandy aquifers, released from continuous major point-source of pollution over a long period of time (91 years ago). This oil refinery contamination resulted mainly in the improper disposal of hydrocarbons and produced water releases caused by equipment failures, vandalism, and accidents that caused direct groundwater pollution or discharge into the gulf. In order to determine the fate of hydrocarbons, detailed field investigations were made to provide intensive deep profile information. Eight composite randomly sediment samples from a test plot were selected for demonstration. The tested plot was 50 m long?×?50 m wide?×?70 cm deep. Sediment samples were collected using an American auger around the point 29° 57' 33? N and 32° 30' 40? E in 2012 and covered an area of 2,500 m(2) which represents nearly 1/15 of total plant area (the total area of the plant is approximately 3.250 km(2)). The detected total petroleum hydrocarbons (TPHs) were 2.44, 2.62, 4.54, 4.78, 2.83, 3.22, 2.56, and 3.13 wt%, respectively. TPH was calculated by differences in weight and subjected to gas chromatography (GC). Hydrocarbons were analyzed on Hewlett-Packard (HP-7890 plus) gas chromatograph equipped with a flame ionization detector (FID). The percentage of paraffine of the investigated TPH samples was 7.33, 7.24, 7.58, 8.25, 10.25, 9.89, 14.77, and 17.53 wt%, respectively. PMID:25052330

Spatial distribution of radioisotopes in the coast of Suez Gulf, southwestern Sinai and the impact of hot springs.  

PubMed

This work describes the concentrations of radioisotopes in soil, sediment, wild plants and groundwater in southwestern Sinai. The study area extends from Suez to Abu Rudies along the eastern part of the Suez Gulf. It included two hot springs: Ayun Musa and Hammam Faraoun. No dependence of ¹³?Cs concentrations on any of the measured sand characteristics was found, including calcium carbonate. The enrichment of ²²?Ra in Hammam Faraoun hot spring was the most prominent feature. The ²²?Ra concentration in hot springs of Ayun Musa and Hammam Faraoun were 68 and 2377 Bq kg?¹ for sediments, 3.5 and 54.0 Bq kg?¹ for wild plants and 205 and 1945 mBq l?¹ for the groundwater, respectively. In addition, ²²?Ra activity concentration in local sand in the area of Hammam Faraoun was ?14 times that of Ayun Musa. On the other hand, the ²³²Th concentrations were comparable in the two hot springs, while ¹³?Cs concentrations were relatively higher in Ayun Musa. The characteristics and radioelements studies support possible suggestions that the waters in the two hot springs have different contributions of sea and groundwaters crossing different geological layers where the water-rock interaction takes place.

Stress field in the central and northern parts of the Gulf of Suez area, Egypt from earthquake fault plane solutions  

NASA Astrophysics Data System (ADS)

Earthquake focal mechanism solutions from 18 events in the central and northern parts of the Gulf of Suez with local magnitudes ranging from 2.8 to 5.2 and occurring between 1983 and 2004 are used to determine the type of motion and stress pattern of the region. Fault plane solutions show mostly normal component; pure normal faulting mechanisms and normal faulting with a strike-slip component. Only some mechanisms show pure strike-slip faulting. The fault planes strike in NW, WNW, NNE and ENE directions, in conformity with the geologically observed striking faults in the northern and central parts of the gulf. The principal stress orientation is also estimated by inverting the selected focal mechanism solutions. The results show that the northern part of the Gulf is subjected to NE-SW to NNE-SSW extension, with a horizontal ?3 (plunge 3°) and subvertical ?1 (plunge 80°). This means that the horizontal extensional stresses are still present in the central/northern Gulf of Suez.

Distribution and statistical analysis of leachable and total heavy metals in the sediments of the Suez Gulf.  

PubMed

The concentrations of nine heavy metals (Cd, Co, Cr, Cu, Fe, Mn, Ni, Pd and Zn) in the labile and total fractions of muddy and sandy sediment samples collected from twelve sites in Suez Gulf during April 1999 were studied to evaluate the pollution status of the Suez Gulf. The enrichment factors (EF) for each element were calculated. There are extremely high concentrations of Cd, Ni, Pb and slightly concentration of Cr and Cu in both muddy and sandy sediments. The concentration of Zn was moderately high and can be considered as seriously contaminate Metal pollution index (MPI) shows high values ranged between 46 to 156 and 40 to 232 for both sandy and muddy sediments, respectively. Concentrations of heavy metals were normalized against iron for total fraction in both of sandy and muddy sediments. Principal component analysis (PCA) was studied on the data matrix obtained and represented three-factor model explaining 92.22% for labile and 88.82% for total fractions of muddy sediment. The main source of contamination is the offshore oil fields and industrial wastes. This is largely a result of ineffective and inefficient operation equipment, illegal discharge of dirty ballast water from tankers and lack of supervision and prosecution of offenders. PMID:16897536

Ecological Study on Community of Exotic Invasive Seaweed Caulerpa prolifera in Suez Canal and its Associated Macro Invertebrates  

NASA Astrophysics Data System (ADS)

Caulerpa prolifera (Forsskal) Lamouroux, a green alga, widespread in tropical and subtropical seas is now invading species to the Suez Canal during last recent years after 2000; it is widely spread, colonizing its western sandy shore at shallow waters of 1-2 m depth. It has the potential to supplant native vegetation, thereby altering the structure and function of the subtidal marine landscape, supplant seagrass H. stipulacea. According to the present study, based on biometric parameters, the frequency of occurrence, abundance and density analyses, the seaweed C. prolifera is more frequent, abundant and dense in Suez Canal than the seagrass H. stipulacea, which is very rare. Instead C. prolifera forming extended dense meadows with percentage cover nearly 100% m-2 at many sites. This mainly happened; due to the competitive success of C. prolifera which seems to be related to its big size, high density, rapid growth, high efficiency in dim light conditions, high tolerance to severe nutrient limitation and salinity and temperature fluctuations and to the production of toxic secondary metabolites. The presence of these toxic secondary metabolites explains why C. prolifera is avoided by many of macro invertebrates as a habitat or feeding grounds.

Pattern of mantle thinning from subsidence and heat flow measurements in the Gulf of Suez: Evidence for the rotation of Sinai and along-strike flow from the Red Sea  

NASA Astrophysics Data System (ADS)

We have undertaken a combined analysis of tectonic subsidence, heat flow and uplift data for the Gulf of Suez. Results show significant differences along the length of the rift. The heat flow and subsidence in the northern Gulf of Suez can be fitted by close to uniform extension in the early Miocene with minimal extension since the middle Miocene. In contrast, the southern Gulf of Suez requires that the early Miocene extension is followed by both continuous slow (˜1 mm/yr) extension and mantle thinning greatly in excess of the crustal thinning. The continued extension of the southern Gulf of Suez is interpreted as indicating a counterclockwise rotation of the Sinai Peninsula that allows the southern Gulf of Suez to accommodate 10-15% of the motion of the Dead Sea transform. Our best estimate of the net crustal and mantle extension factors for southern Suez are ?=1.4-1.5 and ?=2.2-2.6, respectively. While these values are approximate, they indicate a significant input of heat into the southern Gulf of Suez rift that is in excess of that directly advected by extension. Modeling indicates that while ˜1/2 of the extension occurred in the early Miocene, most of the lithospheric thinning, and virtually all of the excess thinning of the mantle lithosphere, developed since then. In addition, the Gulf of Suez is bordered by large and growing rift flank uplifts, particularly on the Sinai Peninsula. The geometry of the motions at the Sinai triple junction region has created a large contrast in extension between the Red Sea and Gulf of Suez-Sinai since the middle Miocene. These lateral temperature gradients drove the flow of hot material that is responsible for the extra heating beneath southern Suez and Sinai. The rift flank uplift along most of the Gulf of Suez is interpreted as resulting from a combination of secondary convection and flexure. The much greater uplift in southern Sinai is produced by the additional convective flow from the Red Sea.

Eliciting maltreated and nonmaltreated children's transgression disclosures: narrative practice rapport building and a putative confession.  

PubMed

This study tested the effects of narrative practice rapport building (asking open-ended questions about a neutral event) and a putative confession (telling the child an adult "told me everything that happened and he wants you to tell the truth") on 4- to 9-year-old maltreated and nonmaltreated children's reports of an interaction with a stranger who asked them to keep toy breakage a secret (n = 264). Only one third of children who received no interview manipulations disclosed breakage; in response to a putative confession, one half disclosed. Narrative practice rapport building did not affect the likelihood of disclosure. Maltreated children and nonmaltreated children responded similarly to the manipulations. Neither narrative practice rapport building nor a putative confession increased false reports. PMID:24467688

Application of well log analysis for source rock evaluation in the Duwi Formation, Southern Gulf of Suez, Egypt  

NASA Astrophysics Data System (ADS)

Several models were developed to use the conventional wireline logs for evaluating the thermal maturity of the source rock and calculating the total organic carbon (TOC) content. Application of these models for the Duwi Formation, southern Gulf of Suez, Egypt, is the main purpose of this paper. Gamma ray, density, sonic, resistivity and neutron are the commonly used wireline logs to identify and quantify source rock. The results, which compared with the results obtained from the Rock-Eval pyrolysis show that cautions must be taken into consideration when applied these models because most of the models are empirical and their validation takes place under certain conditions. It can be concluded that the Duwi Formation represents very good source rock capable of generating a significant amount of hydrocarbon of oil-prone type II. The kerogen is waxy sapropel related to marine plankton deposited under reduced condition.

Low-angle normal faulting and isostatic response in the Gulf of Suez: Evidence from seismic interpretation and geometric reconstruction  

NASA Astrophysics Data System (ADS)

Tectonic extension within continental crust creates a variety of major features best classed as extensional orogens. These features have come under increasing attention in recent years, with the welding of field observation and theoretical concepts. Most recent advances have come from the Basin and Range Province of the southwestern United States and from the North Sea. Application of these geometric and isostatic concepts, in combination with seismic interpretation, to the southern Gulf of Suez, an active extensional orogen, allows generation of detailed structural maps and geometrically balanced sections which suggest a regional structural model. Geometric models which should prove to be a valuable adjunct to numerical and thermal models for the rifting process are discussed.

Engineering applications of seismic refraction method: A field example at Wadi Wardan, Northeast Gulf of Suez, Sinai, Egypt  

NASA Astrophysics Data System (ADS)

Fourteen shallow seismic refraction profiles were conducted in Wadi Wardan, northeast Gulf of Suez, Sinai to delineate some of the shallow soil engineering characteristics for construction purposes. Both compressional (P) and shear (S) waves were acquired and interpreted using Generalized Reciprocal Method (GRM) then the resulted velocity-depth model is verified using a Finite Difference (FD) method to improve the final velocity-depth model. A number of engineering parameters such as Concentration Index, Material Index, Density Gradient, and Stress Ratios are calculated. The seismic velocity values, engineering, consolidation, and strength parameters show that the bedrock at northern and southern parts of the study area is characterized by less competent rock quality, while the central part is characterized by more competent rock quality. Hence, the central part is suggested for construction activities.

Cretaceous petroleum-bearing rock types—their diagenesis and significance in the Gulf of Suez area, Egypt  

NASA Astrophysics Data System (ADS)

Detailed petrographic studies of cores of Cretaceous sediments from the Gulf of Suez area, from both productive and non-productive fault blocks, reveal the rock types, their petrophysics, the nature and distribution of their cements and the effect of diagenesis on hydrocarbon migration and accumulation. An understanding of the petrographic and sedimentologic characteristics of these clastic and non-clastic sediments helps in a valid interpretation of their depositional history and their significance in petroleum exploration. This study is important because of the observed complexity of the virtually unexplored areas and sections of buried Cretaceous rocks in the Gulf of Suez petroleum province, caused by the combined effects of sedimentation and tectonic movements that shaped the Gulf as an intercontinental juncture. There are four petrographic groups, arenite, micrite, wackestone, and claystone. Each group is subdivided into main types and subtypes that reflect the environmental changes within the shallow, fluctuating basin of deposition in the Gulf and related areas. In order to elucidate the porosity changes, the dolomitization process and the clay fractions were investigated. It appears that a post-compactional mechanism is responsible for providing the medium with the Fe 2+, Mg 2+ and K + needed for dolomite formation. Consequently, a porosity decrease may arise from the effect of argillaceous-rich carbonate portions. Also, the decrease of porosity of the Matulla Formation (Lower Senonian sandstone) as compared to the pre-Cenomanian sandstone is the result of increasing overgrowth of secondary silica. Significant dolomitization has increased the porosity of the Lower Seronian—Turonian sediments. This is due to the difference in ionic radii between calcite and dolomite crystal packing. Thus, the petrographic variability of the studied sediments and their diagenesis reflect the variability of their capacity as petroleum-bearing rocks, both laterally and vertically.

Interaction of counseling rapport and topics discussed in sessions with methadone treatment clients.  

PubMed

Therapeutic rapport between counselors and clients in drug user treatment has been shown to be an important predictor of follow-up outcomes. This naturalistic study investigated the relationship of counseling rapport to drug-related topics discussed in counseling sessions in a sample of 330 clients and nine counselors. These voluntary clients had been admitted to a private, for-profit outpatient methadone treatment in Texas between September 1995 and August 1997 and received no-fee services for a year for participation in this study. The data were gathered using forms in the TCU community treatment assessments (www.ibr.tcu.edu) that measured intake information, counseling session topics, and counselor evaluation of the client. A majority were males, Hispanic, had a pending legal status and the average age was 39. Co-occurring drug dependence for these heroin users included cocaine (38%) and alcohol (31%). The results supported the hypothesis that higher rapport would be associated with addressing clients in a more "supportive approach" that emphasized relapse prevention and strengths-building while lower rapport would be associated with a punitive counseling style that stressed program rules and compliance. The influences of client background, counselor differences, and during-treatment positive urines were also examined. Although counselors differed in their general manner of dealing with clients, each also showed flexibility determined in part by client behavior (such as continued cocaine use). The findings indicate that focusing on constructive solutions is the preferred counseling approach. PMID:19137479

Marine integrons containing novel integrase genes, attachment sites, attI, and associated gene cassettes in polluted sediments from Suez and Tokyo Bays  

PubMed Central

In order to understand the structure and biological significance of integrons and associated gene cassettes in marine polluted sediments, metagenomic DNAs were extracted from sites at Suez and Tokyo Bays. PCR amplicons containing new integrase genes, intI, linked with novel gene cassettes, were recovered and had sizes from 1.8 to 2.5?kb. This approach uncovered, for the first time, the structure and diversity of both marine integron attachment site, attI, and the first gene cassette, the most efficiently expressed integron-associated gene cassette. The recovered 13 and 20 intI phylotypes, from Suez and Tokyo Bay samples, respectively, showed a highly divergence, suggesting a difference in integron composition between the sampling sites. Some intI phylotypes showed similarity with that from Geobacter metallireducens, belonging to Deltaproteobacteria, the dominant class in both sampling sites, as determined by 16S rRNA gene analysis. Thirty distinct families of putative attI site, as determined by the presence of an attI-like simple site, were recovered. A total of 146 and 68 gene cassettes represented Suez and Tokyo Bay unsaturated cassette pools, respectively. Gene cassettes, including a first cassette, from both sampling sites encoded two novel families of glyoxalase/bleomycin antibiotic-resistance protein. Gene cassettes from Suez Bay encoded proteins similar to haloacid dehalogenases, protein disulfide isomerases and death-on-curing and plasmid maintenance system killer proteins. First gene cassettes from Tokyo Bay encoded a xenobiotic-degrading protein, cardiolipin synthetase, esterase and WD40-like ? propeller protein. Many of the first gene cassettes encoded proteins with no ascribable function but some of them were duplicated and possessed signal functional sites, suggesting efficient adaptive functions to their bacterial sources. Thus, each sampling site had a specific profile of integrons and cassette types consistent with the hypothesis that the environment shapes the genome. PMID:21248857

Modulation of stress related protein genes in the bass (Epinephelus guaza) caught from the Gulf of Suez, the Red Sea, Egypt.  

PubMed

Impact of chemical pollution on expression of stress protein genes in the bass Epinephelus guaga collected from several locations including Suez Oil Production Port (Floating port), Atakah Fishing Port, Adabiya Port and Tawfik Port in Suez Governorate, Egypt, was investigated. In the current study, levels of polycyclic aromatic hydrocarbons (PAHs) in water and fish samples collected from Suez Gulf were assessed. In addition, gills and liver tissues of caught bass fish were used to address the interaction between pollution status and the expression of stress-related genes (Hsp70a, Hsp70b, Hsp47, MT and CYP1A). Our analysis demonstrated that levels of PAHs in Floating and Tawfik ports were higher than those found in the Atakah Fishing Port and the Adabiya Port. In addition, MDA and PC contents were significantly higher in gills and liver tissues collected from Floating and Tawfik ports than those collected from Adabiya and Atakah ports. In correlation to the above results, all fish collected from the Floating and Tawfik ports presented a significant increase in Hsp-, MT- and CYP1A-mRNAs. On the other hand, fish samples collected from the Atakah Fishing and Adabiya ports showed no induction of the stress-related genes transcription in such tissues. In conclusion, the current research demonstrates that remarkable increase in PAH contaminants levels in Floating and Tawfik ports are correlated with the levels stress protein-related genes transcription in E. guaga gills and liver tissues.

Fission-track analysis of basement apatites at the western margin of the Gulf of Suez rift, Egypt: evidence for synchroneity of uplift and subsidence  

NASA Astrophysics Data System (ADS)

Fifty-six apatite fission-track ages and 52 horizontal confined track-length measurements are reported from Precambrian crystalline rocks along the western margin of the Gulf of Suez, Egypt. Ages fall in the range of ca. 11-385 m.y. and older ages often occur within very close geographic proximity to younger ones, indicating non-uniform uplift. The wide range in ages is accompanied by a systematic variation in the distribution of horizontal confined fission track lengths. On the basis of apatite fission track ages and their length distributions, data fall into three distinct groups. Group I: ages ranging from 43 to 385 m.y. Length distributions are all positively skewed and with decreasing age become progressively broader with shorter mean track length. Group II: ages ranging from 23 to 31 m.y. Length distributions are negatively skewed with either a distinct tail or a small peak of short tracks. Group III: ages ranging from 11 to 20.5 m.y. Length distributions are al unimodal, narrow, negatively skewed and have the longest mean lengths among samples studied. Apatite ages from groups I and II are interpreted as "mixed ages" as a result of cooling during uplift from different levels within the apatite partial track annealing zone. Ages from Group III are interpreted as "cooling ages" due to uplift from the apatite total track annealing zone with minor partial annealing. Correcting the ages of the two oldest samples in this group for track-length reduction yields ages of 21 ± 2.2and23 ± 1.5m.y. It is proposed that the onset of rift-flank uplift in the Gulf of Suez—northern Red Sea area occurred between 21 and 23 m.y. ago. Fission-track analysis in combination with subsidence data from the Gulf of Suez basin, indicate that commencement of basement uplift postdate the start of rifting and is interpreted as evidence for passive rifting at the Gulf of Suez. Furthermore, this uplift is contemporaneous with, and is directly related to, the process of extension and subsidence at the Gulf of Suez.

Mechanical response to stratigraphic inhomogeneity during extension, and surface expression of buried structures, Gulf of Suez, Egypt  

NASA Astrophysics Data System (ADS)

Mechanical response of the stratigraphic succession to rifting in the Gulf of Suez, Egypt, varies depending on the degree of competence of the rock units. This "mechanical stratigraphy" has been documented by observational evidence from field surveys in the northern Esh el Mallaha and in the Ras Issaran area, in conjunction with seismic reflection data. Complex response patterns to basement-rooted block faulting is seen on several scales in both the prerift and synrift rocks. The prerift section is divided into three major units based on mechanical response: Precambrian basement, pre-Cenomanian "Nubian sandstone," and Cenomanian-through-Eocene stable platform marine rocks. Brittle faulting in the basement propagates into the Nubian sandstone by densely fracturing the latter parallel to the fault planes. The overlying inhomogeneous Cenomanian-Eocene section drapes and folds over underlying structural elements. These rocks contain complicated structures due to the interlayering of thin brittle and ductile beds. The incompetent units allow bedding-parallel detachment and also flow into voids created during faulting or folding of the competent units. The synrift section comprises three major stratigraphic units, each of which reacts differently to block faulting. These are the early Miocene carbonate/clastic section, the middle-late Miocene evaporite section, and the onshore Pliocene-Recent clastic passive-cover sequence. In general, the lower synrift rocks respond to deformation much like the Cenomanian-Eocene units, draping and folding due to interlayered brittle and ductile beds. Seismic reflection data indicate that the evaporite section is a major detachment zone, with faults in underlying units dying out upwards, as the ductile salts or anhydrites drape and flow. Structural response in this section is varied and complex. The deformation of the evaporites breaks the overlying passive-cover rocks, with faults in the latter soling into the underlying ductile strate. On gravel plains flanking the Gulf of Suez, the neotectonic fault pattern and resulting topographic and drainage changes reflect underlying structures. The faults breaking the passive cover sequence at the surface initially form en echelon traces; with continued movement these coalesce into straight or curved, often splaying, fault traces. Where the evaporite section reaches a significant thickness, the structures seen at the surface may be entirely decoupled from those of the prerift and early synrift sequences.

Q-values for P and S waves in Southern Sinai and Southern Gulf of Suez Region, Egypt  

NASA Astrophysics Data System (ADS)

The quality factor Q has been estimated using spectral amplitudes of P and S waves from earthquakes recorded by the seismic network of the Egyptian National Seismological Network (ENSN) in southern Sinai and southern Gulf of Suez region. The earthquakes recorded at nine stations - DHA, NUB, TR1, TR2, KAT, SH2, GRB, HRG and SFG have been used in this study. The spectral amplitude ratios have been calculated between 2 - 20 Hz and single station spectral ratio method has been applied for this purpose. The results show that the quality factors for both P and S waves (Qp and Qs) increase as a function of frequency according to law the Q = Q0fn. By averaging the estimated Q- Value obtained at all stations we calculated the average attenuation laws: Qp = (13.15± 0.76) f0.95± 0.19 and Qs = (20.05± 0.79) f1.03±0.04 for P and S waves respectively. These relations are useful for the estimation of source parameters of earthquakes and simulation of earthquake strong ground motions. The QS /QP ratio for KAT station is less than 1 at lower frequencies, whereas at HRG and SH2 stations QS /QP ratio is are greater than 1.

Kinematics of the oblique faults in the east central Gulf of Suez Rift, Wadi Araba, Sinai Peninsula, Egypt  

NASA Astrophysics Data System (ADS)

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

Concentrations of Cd, Pb, Cu and Zn were determined in water, sediments, gastropod ( Bulla umpulla) and green algae ( Ulva lactuca) collected from five stations in the western side of the northern part of the Gulf of Suez during the period February 1993-January 1994. Sediments recorded the highest concentrations of Cd (2.26-4.40 ?g/g) and Pb (13.90-28.34 ?g/g), While the highest concentrations of the essential metals Cu and Zn were found in B. umpulla (28.19-72.04 and 60.24-108.74 ?g/g, respectively). Water and sediments showed similar spatial distribution patterns for the highest mean values of the different metals. Highest values of the studied metals were found at stations influenced by various pollution sources such as harbours, and sewage and industrial drains. In contrast, the lowest concentrations were observed faraway from any pollution source. Calculations of concentration factors (C.F.) for gastropod and algae showed highest C.F. of Cd (4312.5-8705.9) and Pb (2103.3-8317.9) in algae, and highest C.F. of Cu (5288.9-42376.5) and Zn (3686.7-9631.5) in gastropod.

Mineralogically, the sediments are enriched in both non-opaque and opaque heavy minerals. The heavy minerals are concentrated especially in the size fraction 63-125 ?m. Magnetite is the main opaque mineral, while titanite is the most abundant non-opaque mineral in the two size fractions; 63-125 ?m and 125-250 ?m. The studied sediments are derived from different sources. It seems that the H 2S-rich hydrothermal solutions emanated in Hamam Faraon area, and its surroundings, maintain adequate anoxic conditions for reduction of iron oxy-hydroxides to sulphides. Geochemically, the relative enrichment in the HFSE, Y, REE, Th and U, besides the depletion in some of the heavy metals may suggest that the beach sediments of the study area are strongly influenced by felsic sources such as granites and pegmatites. The signature of the mafic and ultramafic components is feeble. The study area contains significantly high concentrations of some potentially toxic metals such as Pb, Mo, Sn, Cd, Sb, As, Se, Th and U.

Definition of soil characteristics and ground response at the northwestern part of the Gulf of Suez, Egypt  

NASA Astrophysics Data System (ADS)

The area of interest represents the industrial part of Ain El-Sokhna new port, located in the northwestern part of the seismically active Gulf of Suez zone. The main objective of the current study is to estimate the site characteristics of the area of interest in terms of the fundamental frequency and the corresponding peak amplitude using noise measurements. The microtremor measurements were performed at 44 sites distributed over the study area in order to calculate the horizontal-to-vertical (H/V) spectral ratio. The standard spectral ratio (SSR) is used in addition to the numerical modelling of horizontal shear (SH) waves in soil at selected sites in order to have a comparison with the H/V spectral ratio. The required 1D soil models for the numerical modelling of SH-waves were derived from 220 P-wave shallow seismic refraction profiles in addition to 30 SH-wave profiles. Maps of the fundamental frequency (f0) and its corresponding H/V peak amplitude (A0) were provided, and a range of site conditions in the area were shown. The amplification factor results derived from the SSR technique are very similar to those derived from the H/V spectral ratio. In most cases, the H/V spectral ratio proved to be suitable for calculating the fundamental resonance. Results were found to be compatible with the surface geology of the area of interest.

Organic tracers in sediments from the coastal zone of Ras Abu el-Darag, Gulf of Suez  

NASA Astrophysics Data System (ADS)

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

Marine Radioactivity Studies in the Suez Canal, Part II: Field Experiments and a Modelling Study of Dispersion  

NASA Astrophysics Data System (ADS)

In this paper we take advantage of the two field tracing experiments carried out under the IAEA project EGY/07/002, to develop a modelling study on the dispersion of radioactive pollution in the Suez Canal. The experiments were accomplished by using rhodamine B as a tracer, and water samples were measured by luminescence spectrometry. The presence of natural luminescent particles in the canal waters limited the use of some field data. During experiments, water levels, velocities, wind and other physical parameters were recorded to supply appropriate information for the modelling work. From this data set, the hydrodynamics of the studied area has been reasonably described. We apply a 1-D-Gaussian and 2-D modelling approaches to predict the position and the spatial shape of the plume. The use of different formulations for dispersion coefficients is studied. These dispersion coefficients are then applied in a 2-D-hydrodynamic and dispersion model for the Bitter Lake to investigate different scenarios of accidental discharges.

Maastrichtian-Early Eocene litho-biostratigraphy and palægeography of the northern Gulf of Suez region, Egypt  

NASA Astrophysics Data System (ADS)

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

Normal fault growth, displacement localisation and the evolution of normal fault populations: the Hammam Faraun fault block, Suez rift, Egypt  

NASA Astrophysics Data System (ADS)

Fault segment linkage, migration of the locus of fault activity, and displacement localisation were important processes controlling the late Oligocene-Recent evolution of the normal fault population of the Hammam Faraun fault block, Suez rift. Initial fault activity was distributed across the fault block on fault segments that had attained their final length within 1-2 My of rifting. These initial segments then either grew by increasing displacement and linked to form longer segmented fault zones or died, during a rift initiation phase that lasted 6-8 My. Following this rift initiation phase, displacement became localised onto >25-km-long border fault zones bounding the fault block and many of the early high-displacement intra-block fault zones died. Following displacement localisation onto the major faults bounding the fault block, the locus of maximum displacement continued to migrate, with post-Middle Miocene displacement focused on the western margin of the fault block. This migration of fault activity between major crustal-scale normal faults can be viewed in terms of strain localisation at the rift scale. The results from this study question conventional fault growth models based on final displacement distributions, and highlight the sequential nature of faulting on major normal faults bounding domino-style tilted fault blocks.

Thermal history of the eastern Gulf of Suez, II. Reconstruction from apatite fission track and {40Ar }/{39Ar } K-feldspar measurements  

NASA Astrophysics Data System (ADS)

Apatite fission track (AFT) measurements from Miocene graben-fill sediments of the eastern Gulf of Suez in three deep boreholes (Belayim 113 M-2/6, Ras Garra M-1 and Alma-2) yield a wide range of ages (from 125 to 320 Ma) and mean track-lengths (˜10.1-12.7 ?m). This range is similar to that recorded from Precambrian crystalline basement flanking the graben which is the major source for the rift fill. Since the AFT ages exceed the age of the host strata, which are presently at their highest post-depositional temperatures, the rift-related thermal regime is one of only moderate heating. Downhole AFT data in the Belayim 113 M-2/6 borehole attest to a higher rift temperature than in the Ras Garra M-1 borehole, some 85 km to the south, where little or no thermal overprinting is evident. These findings are consistent with previously reported bottom hole temperatures and vitrinite reflectance data in the study area. Despite the higher syn-rift thermal regime indicated for Belayim 113 M-2/6, apatite provenance ages in Ras Garra M-1 are considerably younger. Thus, the AFT data in the Ras Garra M-1 area do not record significant rift-related thermal effects, but rather, they mainly retain a pre-rift provenance signature which reflects the order and depth of erosion at the uplifted flanks. The younger AFT ages in Ras Garra M-1, despite the weaker rift-related thermal effect, suggest a deeper level proportional to an additional ˜5-10°C of exhumation of the uplifted crystalline basement southwards along the eastern rift flank by Mid-Miocene time. This result is consistent with earlier findings which indicate both increased extension and heat flow southwards in the Gulf of Suez, and earlier exhumation of the rift flank. Immediately preceding extension and opening of the Gulf of Suez, the most deeply exhumed basement rocks presently exposed on the rift flanks were heated to temperatures ?110°C (total annealing of apatite), but <˜170°-200°C as constrained by {40Ar }/{39Ar } data and non-resetting of zircon FT clocks in sinai, {40Ar }/{39Ar } data from granite penetrated in graben drilling at ˜3.89 km further corroborates pre-rift palaeotemperatures <˜170°C for crystalline basement underlying the Gulf of Suez.

Oil pollution in the Red Sea — Environmental monitoring of an oilfield in a coral area, Gulf of Suez  

NASA Astrophysics Data System (ADS)

The Red Sea is rapidly developing as one of the world's largest offshore oil production areas. It also comprises a wide range of tropical marine habitats, many of which are internationally recognised for their conservation, scientific, economic or recreational value. Past oil production, refining and transport have resulted in chronic pollution of some areas, and environmental programmes to protect new areas of development from pollution damage are assuming increasing importance. At the initiative of an Egyptian oil company operating in the Gulf of Suez, an environmental protection and management scheme has been prepared for a new offshore oilfield and marine terminal at Ras Budran. This paper describes the form of the scheme and the results of its component environmental surveys. The development area comprises rich and diverse marine communities of fringing coral reefs, nearshore lagoons, seagrass beds, sandy beaches and fine sediments offshore. A baseline survey was designed following detailed discussion of the scope of the development with the company and a preliminary site visit, and the fieldwork was completed in October 1980. On the basis of the findings of the survey, a series of recommendations was made to the company, aimed at reducing environmental impacts during construction and operation to a minimum and acceptable level. These were subsequently implemented and the results of a post-construction survey in February 1983 are reported which show that environmental damage to the nearshore habitats during the construction phase had been relatively small and localised. Recently, the biological information obtained from the two surveys has also been incorporated into oil spill contingency plans.

Facies and depositional environment of the Holocene evaporites in the Ras Shukeir area, Gulf of Suez, Egypt  

NASA Astrophysics Data System (ADS)

The Holocene evaporite sequence in the Ras Shukeir area conformably overlies marine shell banks and cross-bedded to graded-bedded beach sands and gravels. The evaporite sequence is represented by gypsum-anhydrite layers that are interbedded with mudstone layers. Field and petrographic investigations of the evaporite deposits revealed two facies types, laminated evaporite facies (primary) and nodular to enterolithic anhydrite facies (diagenetic). The laminated evaporite facies is subdivided, from the bottom to top, into regular laminated evaporite, chevron gypsum-algal micrite laminations and wavy algal laminated evaporite. Based on their textures and fabrics, the regular and wavy laminated evaporite facies are interpreted as primary deposits in a coastal lagoon and salina environment. The chevron gypsum-algal micrite facies formed by the growth of chevron gypsum at the sediment-water interface within a shallow subtidal lagoonal environment that was characterized by extensive benthic algal mats. The nodular to enterolithic anhydrite facies is secondary and formed diagenetically within a siliciclastic supratidal sediment. Some of the laminated evaporite facies have been diagenetically altered in a supratidal sabkha environment as evidenced by the following: (1) the partial formation of nodular evaporite instead of laminated evaporite; (2) disruption of gypsum laminations by plant roots and rootlets as well as by precipitation of lenticular gypsum on the root wall; and (3) partial dissolution of halite laminae and the formation of wavy anhydrite laminae. Consequently, the Holocene evaporites in the Ras Shukeir area were deposited in a shallow semi-closed to closed basin that was separated from the Gulf of Suez trough. Changing sea level led to progradation of the evaporite facies from subtidal to intertidal lagoon and salina to a supratidal sabkha.

Provenance, diagenesis, tectonic setting and reservoir quality of the sandstones of the Kareem Formation, Gulf of Suez, Egypt  

NASA Astrophysics Data System (ADS)

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

Provenance, diagenesis, tectonic setting and geochemistry of Rudies sandstone (Lower Miocene), Warda Field, Gulf of Suez, Egypt  

NASA Astrophysics Data System (ADS)

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

"Straight up": enhancing rapport and therapeutic alliance with previously-detained youth in the delivery of mental health services.  

PubMed

A strong therapeutic alliance has been shown to improve mental health treatment outcomes in adults, but this topic has not been fully explored with youth. Adolescents, particularly justice-involved youth, stand to benefit greatly from an improved treatment experience. One quality which can improve treatment is mental health providers' interpersonal skills when attempting to build a therapeutic rapport with adolescent clients. Semi-structured interviews were conducted with 19 youth who screened positive for mental health concerns while in juvenile detention. Four themes were identified as important to improving the therapeutic alliance: Empathy, client-directed care, sequencing, and positive rapport. Suggestions for strengthening a therapeutic alliance are provided. PMID:23775240

Evaporitic and biosiliceous cyclic sedimentation in the Miocene of the Gulf of Suez—Depositional and diagenetic aspects  

NASA Astrophysics Data System (ADS)

The Middle to Late Miocene evaporite-bearing formations which outcrop along the Gebel Zeit and Gems highs in the southwestern Gulf of Suez (Egypt), consist of thick calcium sulphate beds rhythmically interbedded with marlstones, siltstones and claystones containing various amounts of biogenic silica, as well as pure diatomites. The calcium sulphate beds are composed mainly of gypsum and anhydrite. Subaqueous crustallisation in subpermanent brine ponds of marine origin predominated during deposition of the selenite and laminated gypsum. Early diagenetic interstitial growth of nodular anhydrite occurred episodically when the water level dropped, in response to increasing salinity associated with the precipitation of halite in the deeper troughs. Nevertheless, most of the nodular facies resulted from the burial conversion of gypsum to anhydrite which has been sometimes rehydrated into gypsum. A last phase of gypsum dehydration has occurred at the surface, related to the present hot and dry climatic conditions. The biosiliceous deposits contain either well preserved (opal-A) or diagenetically altered (opal-CT, clinoptilolite, quartz and even clays) diatom frustules. Such diagenetic changes are commonly described in the oceanic biosiliceous deposits. The fossil content of these diatomitic layers implies shallow-marine conditions on the shelves of highs induced by block faulting. The cyclic succession of evaporited and biosiliceous deposits recorded the alternation of high sea level stands associated with high organic productivity, probably enhanced by seasonal input of nutrients and low sea level stands associated with hypersaline conditions and evaporite deposition. Locally, the sharp contact between the diatomites and gypsum argues for a rapid evolution of salinity towards high concentration (up to gypsum saturation and more). The formation of finely laminated diatomitic sediments is known to require either high organic productivity or anoxic conditions in bottom/intermediate waters, and eventually both processes. In the Gebel Zeit and Gemsa areas, a local association of the biosiliceous sediments with diagenetic carbonates and native sulphur, resulting from processes of bacterial sulphate reduction, confirms that anoxic conditions occurred in the deep-water body or in the sediments. Large amounts of organic compounds were involved in these diagenetic processes. Immature organic matter was consumed during an early diagenetic stage of transformation. It is assumed that this organic matter was supplied either by the biosilica-rich interbeds or the organic-rich laminated carbonates. The initial organic content of the biogenic deposits was impoverished as early as the first stages of sedimentation and diagenesis. Although a large part of the organic matter could have been destroyed by these early diagenetic processes and further oxidation in outcrops, these sediments can be considered as potential source rocks in nearby less exposed sequences.

The multistage tectonic evolution of the Gulf of Suez and northern Red Sea continental rift from field observations  

NASA Astrophysics Data System (ADS)

Field surveys in the Gulf of Suez-Northern Red Sea area revealed the structural pattern and evolution of this tertiary continental rift and provided constraints on the continental rifting process. The structure has been controlled, at every scale, by four major trends of faults: N0°-20°E, N100°-120°E, N140°E-160°E and N40°-60°E. Observations of sealed faults and folds and superposed structures and the detailed analysis of the fault surfaces are coherent and indicate that as least two different stages of deformation characterize the evolution of the rift. The initiation of the rift (late Oligocene-Aquitanian) corresponds to the creation of large rhomboidal basins, weakly subsident and partly bounded by oblique strike-slip faults. This framework, which resulted from the reactivation of inherited weakness zone in the basement, controlled the subsequent creation of large tilted blocks (upper Aquitanian-lower Burdigalian). These structures were trangressed by the upper Burdigalian deposits. Then the blocks were sliced by a secondary horst and graben pattern, which was progressively sealed by middle Miocene units. Since the upper Miocene, the deformation has been focused along some major faults located in the central part of the rift. The determination of paleostresses from measurements of striae confirms that the initiation of the rift was controlled by a tectonic regime characterized by an horizontal compressive stress parallel to the rift, and its subsequent evolution was controlled by triaxial and radial extensional regimes with horizontal minimum stress (?3) predominantly trending N70°-80°E. The rifting process was not induced by regional doming but by a new distribution of intraplate stresses at approximately Oligocene-Miocene time (passive rift). Uplift of the rift shoulders began in the upper Burdigalian. Cross sections of the rift emphasize its asymmetry: large basement blocks are tilted toward the edge of the rift where a major, recently active fault and a distinct morphological unit, which we call a "banquette," are located. Several homogeneous tilt direction provinces can be defined. They are separated by transverse hinge zones that correspond to inherited basement trends. Rifting deformation is expressed in the basement by steep faults arranged in a zig-zag pattern and in Neogene-Quaternary sediments by steep faults and listric faults associated with decollements. Therefore the style of shallow deformation cannot be extrapolated to deeper levels. Structures formed during the beginning of the rift show different charateristics according to their orientation, but their initial shape was generally complicated by later deformation.

Sedimentology of rift climax deep water systems; Lower Rudeis Formation, Hammam Faraun Fault Block, Suez Rift, Egypt  

NASA Astrophysics Data System (ADS)

In most marine rift basins, subsidence outpaces sedimentation during rift climax times. Typically this results in sediment-starved hangingwall depocentres dominated by deep-marine mudstones, with subordinate local development of coarser clastics in the immediate hangingwall derived from restricted catchments on the immediate footwall scarp. To highlight the spatial variability of rift climax facies and the controls upon them, we have investigated the detailed three-dimensional geometry and facies relationships of the extremely well exposed Miocene, rift climax Lower Rudeis Formation in the immediate hangingwall to the Thal Fault Zone, Suez Rift, Egypt. Detailed sedimentological analyses allows the Lower Rudeis Formation to be divided into two contemporaneous depositional systems, (1) a laterally continuous slope system comprising, hangingwall restricted (< 250 m wide) slope apron, slope slumps, fault scarp degradation complex and laterally extensive lower slope-to-basinal siltstones, and (2) a localized submarine fan complex up to 1 km wide and extending at least 2 km basinward of the fault zone. Interpretation of individual facies, facies relationships and their spatial variability indicate that deposition in the immediate hangingwall to the Thal Fault occurred via a range of submarine concentrated density flows, surge-like turbidity flows, mass wasting and hemipelagic processes. Major controls on the spatial variability and stratigraphic architecture of the depositional systems identified reflect the influence of the steep footwall physiography, accommodation and drainage evolution associated with the growth of the Thal Fault. The under-filled nature of the hangingwall depocentre combined with the steep footwall gradient result in a steep fault-controlled basin margin characterised by either slope bypass or erosion, with limited coastal plain or shelf area. Sediment supply to the slope apron deposits is controlled in part by the evolution and size of small footwall drainage catchments. In contrast, the localized submarine fan is interpreted to have been fed by a larger, antecedent drainage network. The structural style of the immediate footwall is also believed to exert a control on facies development and stratigraphic evolution. In particular, fault scarp degradation is enhanced by fault propagation folding which creates basinward-dipping bedding planes in the pre-rift footwall strata that large pre-rift blocks slide on.

Résultats La prévalence du diabète en hémodialyse est 21,6%. L’âge moyen 59±13,2 ans (26-87). Le sex-ratio est de 1,9. L'IMC moyen est de 24,5 ± 4,4 kg/m2 (15-41). 42 patients sont porteurs d?une hépatite virale. La durée moyenne en HD est 39,3± 67 mois. 57% des patients gardent une diurèse résiduelle versus 43% chez les non diabétiques. Par rapport à ces derniers, nous avons noté plus d'HTA (64% versus 45%), plus de complications cardiovasculaires (23% versus 12%), un âge plus avancé à l'initiation de l'hémodialyse (55,5 versus 47 ans) et un taux de FAV proximales plus important. Conclusion La prévalence des diabétiques en hémodialyse est relativement élevée au Maroc sans tenir compte des patients qui ne bénéficient pas d’épuration extra-rénale pour des raisons socio-économiques. Le taux élevé de mortalité est imputable au retard et/ou à l'absence de la prise en charge néphrologique des diabétiques. Dans nos régions où le système sanitaire dispose de faible moyen, l'accent doit être mis sur le dépistage précoce de la néphropathie chez le diabétique. PMID:25374630

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

NASA Astrophysics Data System (ADS)

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

Late Quaternary reorientation of stress field and extension direction in the southern Gulf of Suez, Egypt: Evidence from uplifted coral terraces, mesoscopic fault arrays, and borehold breakouts  

NASA Astrophysics Data System (ADS)

Uplifted Pleistocene coral terraces and modern earthquakes show that several large normal faults are presently active in the southern Gulf of Suez rift basin. The footwall of one of these faults is exposed at Gebel el Zeit, where terraces at elevations of +10-18 and +42 m have been radiometrically dated as 125 ka and 426 ka, respectively. After correcting for eustatic sea-level changes, this results in net tectonic uplift rates of about 0.1 m/kyr. Published interpretations and our own observations indicate that the average extension direction during the Miocene to Pliocene synrift history was 055°. Analysis of borehole breakouts and published earthquake fault plane solutions, however, suggests that the present-day stress field in the southern Gulf has a 010°-020° Shmin orientation. Detailed structural observations show that a change in extension direction occurred in the late Pleistocene, with rotation of the stress field beginning prior to formation of the 125 ka terraces but after formation of older Pleistocene terraces whose ages are less tightly constrained. Using a horizontal slip direction of 015° and our observed net footwall uplift rate, we calculate a separation velocity between Sinai and Africa of 0.8-1.2 m/kyr. The proposed Pleistocene change in extension direction in the Gulf of Suez corresponds closely with the post-500 ka change in extension direction documented in the Kenyan rift system and a similar change in extension direction recorded in the central Red Sea. These regional similarities in tectonic history suggest that the underlying causes of these events may be a plate-scale phenomenon affecting the entire Afro-Arabian rift system, rather than local changes in the Quaternary stress field.

Biostratigraphy and paleoecology of the Burdigalian-Serravallian sediments in Wadi Sudr (Gulf of Suez, Egypt): comparison with the Central Paratethys evolution  

NASA Astrophysics Data System (ADS)

Two main Miocene facies were recorded in the Gulf of Suez area: a deep marine and a coastal facies. The analysed sections in the Wadi Sudr area belong to the marine facies. The Lower Miocene (Burdigalian) is represented by coastal, shallow marine sediments, rich in coral, algae, gastropods and large pectinids followed by Langhian open marine sediments and Serravallian lagoonal carbonates. The open marine sediments contain well preserved planktonic and benthic foraminifers and abundant ostracods. The parts of the sections containing foraminifers have been correlated with three planktonic foraminiferal zones (Praeorbulina glomerosa Zone, Orbulina Zone and Globorotalia praemenardii-Globorotalia peripheroronda Zone). Two benthic ecozones were defined (Heterolepa dutemplei-Laevidentalina elegans Zone and Bolivina compressa-Elphidium spp. Zone). Two cycles of sea-level changes can be distinguished and correlated with global sea-level cycles Bur5/Lan1 and Ser1. The first (Langhian) cycle culminated in open marine sublittoral to upper bathyal well aerated sediments. The second (Serravallian) cycle was shallower, littoral suboxic sediments were overlaid by euryhaline carbonates. The studied foraminifera-bearing sediments can be correlated with the lower and Middle Badenian of the Central Paratethys. Though the area of the Gulf of Suez and the Central Paratethys were situated in different climatic zones, and influenced by different tectonic events, the main paleoenvironmental events (sea-level changes, oxygen decrease, salinity changes) are comparable. This correspondence shows that the decisive factors triggering these events were global climatic events.

When students from different professions are co-located: the importance of interprofessional rapport for learning to work together.  

PubMed

With increasing interest and research into interprofessional learning, there is scope to more deeply understand what happens when students from different professions live and study in the same location. This study aimed to explore the issue of co-location and its effects on how students learn to work with other professions. The setting for this study was a rural health education facility in Australia with close links to local health care and community services. Philosophical hermeneutics informed the research method. Interviews were undertaken with 29 participants, including students, academic educators and clinical supervisors in diagnostic radiography, medicine, nursing, nutrition and dietetics, pharmacy, physiotherapy, occupational therapy, and speech pathology. Photo-elicitation was used to facilitate participant engagement with the topic. The findings foreground the value of interprofessional rapport building opportunities for students learning to work together. Enabled by the proximity of different professions in shared educational, clinical and social spaces, interprofessional rapport building was contingent on contextual conditions (balance of professions, shared spaces and adequate time) and individual's interpersonal capabilities (being interested, being inclusive, developing interpersonal bonds, giving and receiving respect, bringing a sense of own profession and being patient-centred). In the absence of these conditions and capabilities, negative professional stereotypes may be inadvertently re-enforced. From these findings suggestions are made for nurturing interprofessional rapport building opportunities to enable students of different professions to learn to work together. PMID:25010631

Collective flow in Au + Au collisions  

SciTech Connect

Based on a preliminary sample of Au + Au collisions in the EOS time projection chamber at the Bevalac, we study sideward flow as a function of bombarding energy between 0.25A GeV and 1.2A GeV. We focus on the increase in in-plane transverse momentum per nucleon with fragment mass. We also find event shapes to be close to spherical in the most central collisions, independent of bombarding energy and fragment mass up to {sup 4}He.

Fragment flow in Au+Au collisions  

SciTech Connect

Exclusive measurements have been made of Au+Au reactions with beam energies ranging from 0.25{ital A} to 1.15{ital A} GeV. We present measurements of directed collective flow averaged over all light fragments with masses up to alphas, as well as separate measurements for protons, deuterons, tritons, {sup 3}He, {sup 4}He, and Li. The results show a strong increase of the directed flow with fragment mass at all energies measured. Experimental results are compared with a quantum molecular dynamics model. We find that neither the ``soft`` nor the ``hard`` equation of state can describe the data over the entire range of beam energies.

Relations between normal-fault geometry, tilting and vertical motions in extensional terrains: an example from the southern Gulf of Suez  

NASA Astrophysics Data System (ADS)

Earthquakes and data from subsurface oil exploration suggest that large active normal faults in the southern Gulf of Suez are approximately planar, with dips of 30-40°, from the surface to around 10 km depth. These faults, and the blocks they bound, appear to rotate about a horizontal axis as they move, causing tilting. This tilting is seen both in young vertical movements of the coastline, such as raised beaches and marshlands, and in the distribution of Middle Miocene marine rocks, which are uplifted to elevations of 400-500 m in footwalls of faults and found at depths of around 3500 m in the adjacent grabens. The absolute amplitude of the observed vertical motions can be approximately modelled by planar rotating normal faults that impose a saw-tooth topography on a regional subsidence caused by crustal and lithospheric thinning. The observations required for this simple model are: the present day fault dip, the amount of tilting and the width of the rotating blocks. The virtues of the model are its simplicity and its compatibility with our knowledge of how large active normal faults move elsewhere on the continents.

Style and sequence of deformation during extensional fault-propagation folding: examples from the Hammam Faraun and El-Qaa fault blocks, Suez Rift, Egypt  

NASA Astrophysics Data System (ADS)

Kilometre-scale fault-parallel folds are identified adjacent to normal faults in the Oligo-Miocene Suez Rift, Egypt and are interpreted to have formed in response to fault-propagation folding above upward propagating blind faults. The geometry, scale and distribution of secondary structures within the folds and their cross-cutting relationships with the master faults allow the style and sequence of deformation during fault-propagation folding to be established and suggest that during the initial stages of folding, the proto-footwall underwent extension which was accommodated by layer-parallel slip in encasing mudstone horizons and linked normal faulting and block rotation in carbonate and sandstone units. The proto-hanging wall also contains dominantly extensional normal faults although locally, where the master fault had a convex-into-the-footwall map-view trace, reverse faulting and fracturing occurred. Secondary structures adjacent to the master fault were not all active simultaneously, but initiated and died at different stages during the evolution of the fault-propagation fold. The results of this study confirm many key predictions of numerical and physical analogue models but also highlight several important controls on the evolution of fault propagation folds in extensional settings which existing models cannot capture, such as the influence of the map-view trace of the propagating fault and lateral variations in cover stratigraphy lithology and strength on the style and magnitude of secondary deformation.

@AuAg nanostructures  

NASA Astrophysics Data System (ADS)

Bimetallic and trimetallic nanoparticles have attracted significant attention in recent times due to their enhanced electrochemical and catalytic properties compared to monometallic nanoparticles. The numerical calculations using Mie theory has been carried out for three-layered metal nanoshell dielectric-metal-metal (DMM) system consisting of a particle with a dielectric core (Al@Al2O3), a middle metal Ag (Au) layer and an outer metal Au (Ag) shell. The results have been interpreted using plasmon hybridization theory. We have also prepared Al@Al2O3@Ag@Au and Al@Al2O3@AgAu triple-layered core-shell or alloy nanostructure by two-step laser ablation method and compared with calculated results. The synthesis involves temporal separations of Al, Ag, and Au deposition for step-by-step formation of triple-layered core-shell structure. To form Al@Ag nanoparticles, we ablated silver for 40 min in aluminium nanoparticle colloidal solution. As aluminium oxidizes easily in water to form alumina, the resulting structure is core-shell Al@Al2O3. The Al@Al2O3 particle acts as a seed for the incoming energetic silver particles for multilayered Al@Al2O3@Ag nanoparticles is formed. The silver target was then replaced by gold target and ablation was carried out for different ablation time using different laser energy for generation of Al@Al2O3@Ag@Au core-shell or Al@Al2O3@AgAu alloy. The formation of core-shell and alloy nanostructure was confirmed by UV-visible spectroscopy. The absorption spectra show shift in plasmon resonance peak of silver to gold in the range 400-520 nm with increasing ablation time suggesting formation of Ag-Au alloy in the presence of alumina particles in the solution.

Geophysical Constraints on the Hydrogeologic and Structural Settings of the Gulf of Suez Rift-Related Basins: Case Study from the El Qaa Plain, Sinai, Egypt  

NASA Astrophysics Data System (ADS)

Groundwater has been identified as one of the major freshwater sources that can potentially meet the growing demands of Egypt's population. Gravity data (from 381 ground gravity stations) were collected, processed, and analyzed together with the available aeromagnetic (800 line-km) data to investigate the hydrogeologic and structural settings, areal distribution, geometry, and water storage of the aquifers in El Qaa coastal plain in the southwest Sinai Peninsula, and to assess their longevity given projected extraction rates. Findings include (1) complete Bouguer anomaly and total magnetic intensity maps show two connected sub-basins separated by a narrow saddle with an average basin length of 43 km and an average width of 12 km; (2) two-dimensional modeling of both gravity and magnetic data indicates basin fill with a maximum thickness of 3.5 km; (3) using anomalous residual gravity, the volume of water in storage was estimated at 40-56 km3; and (4) progressive increases in extraction rates over time will deplete up to 40 % of the aquifers' volume in 200-230 years and will cause the water quality to deteriorate due to seawater intrusion in 45 years. Similar geophysical exploration campaigns, if conducted over the entire coastal plains of the Red Sea and the Gulfs of Suez and Aqaba, could assist in the development of sound and sustainable management schemes for the freshwater resources in these areas. The adopted techniques could pave the way toward the establishment of sustainable utilization schemes for a much larger suite of similar aquifers worldwide.

Etude séro-épidémiologique de la leishmaniose canine au centre du Maroc  

PubMed Central

Dans le monde, la leishmaniose viscérale humaine est connue pour avoir comme principale source d'infection les Canidés domestiques et sauvages. Au centre du Maroc, les données épidémiologiques, cliniques et parasitologiques sur la leishmaniose canine, sont quasiment inexistantes. Ce travail traite une étude prospective au cours de laquelle 61 sérums canins ont été analysés par un test rapide et par l'immunofluorescence indirecte. La sensibilité du test rapide par rapport à celle de l'immunofluorescence indirecte (IFI) est de 33,33%. La fréquence de la maladie chez les chiens s’élève à 9,83% (Test Rapide) et 24,59% (IFI). 73,33% des cas canins positifs à la sérologie sont asymptomatiques. Ce sont les jeunes chiens de moins de 5 ans qui sont les plus fréquemment atteints avec une sensibilité de la race Berger Allmand à l'infection. Cette étude a permis de mettre en évidence la présence de chiens leishmaniens (15 chiens séropositifs parmi 61) et de prouver l'existence du réservoir canin. Une stratégie de prévention active doit être mise en place.

La localisation cutanée de la maladie tuberculeuse demeure une forme rare et représente seulement 2,1% des localisations. L'objet de cette étude est de rapporter le profil épidémiologique, anatomoclinique et évolutif des cas de tuberculose ganglio-cutanée diagnostiqués dans un CHU au Burkina Faso. La fréquence de la tuberculose cutanée est très faible au CHUSS. Six cas ont été diagnostiqués entre 2004 et 2010, soit une fréquence de un cas par an. La durée d’évolution des cas allait de deux jusqu’à dix ans avant leur diagnostic. Les lésions observées étaient: trois scrofulodermes, trois gommes, une tuberculose testiculaire associée à un mal de Pott, un cas de polyadénopathies et des cicatrices atropho-rétractiles dans la plupart des cas. Sur le plan anatomopathologique, des granulomes tuberculoïdes ont été mis en évidence dans tous les cas avec une forte réaction tuberculinique à l'IDR. Sous antituberculeux pendant six mois, l’évolution a été bonne dans tous les cas mais au prix de séquelles cutanées cicatricielles inesthétiques. Son ampleur reste peut-être encore méconnue. Le renforcement du plateau technique du CHU et une bonne collaboration interdisciplinaire contribuerait à un meilleur diagnostic et prise en charge de cette affection. PMID:24648863

We report on the fabrication and characterization of CdTe thin-film solar cells with Cu-free MoO3- x /Au back contacts. CdTe solar cells with sputtered CdTe absorbers of thicknesses from 0.5 to 1.75 ?m were fabricated on Pilkington SnO2:F/SnO2-coated soda-lime glasses coated with a 60- to 80-nm sputtered CdS layer. The MoO3- x /Au back contact layers were deposited by thermal evaporation. The incorporation of MoO3- x layer was found to improve the open circuit voltage ( V OC) but reduce the fill factor of the ultrathin CdTe cells. The V OC was found to increase as the CdTe thickness increased.

Heavy metals and hydrocarbon concentrations in water, sediments and tissue of Cyclope neritea from two sites in Suez Canal, Egypt and histopathological effects.  

PubMed

Heavy metals and hydrocarbons are of the most common marine pollutants around the world. The present study aimed to assess the concentration of petroleum hydrocarbons and heavy metals in tissues of the snail cyclope neritea, water and sediments from two sites of the study area (Temsah lake and Suez canal) represent polluted and unpolluted sites respectively. The results showed that, the levels of the heavy metals (Pb, Cd, Co, Mg and Zn) in the polluted area have reached harmful limits recorded globally. Lead in water, sediment and tissue of the snail reached to 0.95 ppm, 4.54 ppm and 7.93 ppm respectively. Cadmium reached 0.31 ppm, 1.15 ppm and 3.08 ppm in the corresponding samples. Cobalt was not detected in water, but it reached 1.42 ppm and 10.36 ppm in the sediment and snails tissue respectively. Magnesium in water, sediment and tissue of the snail reached 3.73 ppm, 9.44 ppm and12.6 ppm respectively. Zinc reached 0.11 ppm, 3.89 ppm and 12.60ppm in the corresponding samples. Meanwhile, hydrocarbons in the polluted area (site1) reached 110.10 ?g/L, 980.15 ?g/g and 228.00 ?g/g in water sediment and digestive gland tissues of the snails respectively. Whereas, hydrocarbons in the unpolluted area (site2) were estimated as 14.20 ?g/L, 55.60 ?g/g and 22.66 ?g/g in water, sediment and tissue of the snails respectively. The combination of histopathological image with monitoring of the metal level in the digestive gland of the present snail provides an important tool for early detection of impending environmental problems and potential public health issues. Petroleum hydrocarbons are toxic to the marine fauna when present above certain limit in the marine water. The major detoxification organ in molluscs is the digestive gland, which has been used as a bioindicator organ for toxicity assessment. The effect of high crude oil on the digestive gland tubules of exposed snails when examined microscopically reveals a series of histological changes which indicates that the cellular compensatory mechanism is activated by hydrocarbons. These changes include vacuolation and presence of pyknotic nuclei. PMID:25878794

Surface morphology and optical properties of porphyrin/Au and Au/porphyrin/Au systems  

NASA Astrophysics Data System (ADS)

Porphyrin/Au and Au/porphyrin/Au systems were prepared by vacuum evaporation and vacuum sputtering onto glass substrate. The surface morphology of as-prepared systems and those subjected to annealing at 160°C was studied by optical microscopy, atomic force microscopy, and scanning electron microscopy techniques.

Surface morphology and optical properties of porphyrin/Au and Au/porphyrin/Au systems  

PubMed Central

Porphyrin/Au and Au/porphyrin/Au systems were prepared by vacuum evaporation and vacuum sputtering onto glass substrate. The surface morphology of as-prepared systems and those subjected to annealing at 160°C was studied by optical microscopy, atomic force microscopy, and scanning electron microscopy techniques. Absorption and luminescence spectra of as-prepared and annealed samples were measured. Annealing leads to disintegration of the initially continuous gold layer and formation of gold nanoclusters. An amplification of Soret band magnitude was observed on the Au/meso-tetraphenyl porphyrin (TPP) system in comparison with mere TPP. Additional enhancement of luminescence was observed after the sample annealing. In the case of sandwich Au/porphyrin/Au structure, suppression of one of the two porphyrins’ luminescence maxima and sufficient enhancement of the second one were observed. PMID:24373347

Le don après un décès d'origine cardiocirculatoire au Canada  

PubMed Central

Résumé Ces recommandations sont le fruit d'un processus multidisciplinaire national ayant duré un an et visant à déterminer si et comment l'on pourrait procéder au don d'organes après un décès d'origine cardiocirculatoire («don après le décès cardiocirculatoire», ou DDC) au Canada. Le forum national organisé en février 2005 a permis aux participants de discuter et d'élaborer des recommandations sur les principes, interventions et pratiques se rapportant au DDC. Les aspects éthiques et juridiques ont été abordés dans les discussions. À la fin du Forum, la majorité des participants ont été favorables à l'implantation de programmes de DDC au Canada. Les participants du Forum ont également convenu qu'il fallait formuler et prôner des valeurs fondamentales pour orienter l'élaboration de programmes et de protocoles basés sur le cadre médical, éthique et juridique établi lors de cette réunion. Même si la possibilité d'un don d'organes et de tissus doit faire partie intégrante des soins de fin de vie, il faut insister sur le fait que le devoir de diligence envers les patients mourants et leurs familles doit demeurer la priorité des équipes soignantes. La complexité et les répercussions profondes du décès sont reconnues et doivent être respectées, de même que les différences personnelles, ethnoculturelles et religieuses face à la mort et au don d'organes. Les décisions d'arrêter le traitement de maintien des fonctions vitales, la prise en charge des derniers moments de la vie et le diagnostic de décès selon des critères cardiocirculatoires doivent être distincts et indépendants des processus de don et transplantation. Ce rapport contient des recommandations destinées aux gestionnaires de program, aux autorités sanitaires régionales et aux instances appelés à élaborer les protocoles de DDC. Les programmes doivent être conçus en fonction des éléments suivants : direction et planification locales, éducation et engagement des intervenants, mécanismes d'assurance de la sécurité et de la qualité et information du public. Il est recommandé de commencer par un program de DDC contrôlé à l'unité de soins intensifs où, après une décision par consentement mutuel de cesser le traitement de maintien des fonctions vitales, la mort est attendue, mais n'est pas survenue, ce qui rend possible des discussions non précipitées sur le consentement. Un don non contrôlé, en cas de décès après un arrêt cardiaque non prévu, doit être envisagé seulement une fois que le program de DDC contrôlé a été établi. Bien qu'il soit recommandé de restreindre le programme initial au don de reins, le don d'autres organes peut aussi être envisagé selon l'expertise régionale en matière de transplantation. Les répercussions d'un DDC, y compris les interventions pratiquées avant et après le décès, sur la famille du donneur, la disponibilité des organes, la fonction du greffon et la survie du receveur doivent être documentées de façon méthodique et examinées.

Universality in fragment inclusive yields for Au + Au collisions  

SciTech Connect

The inclusive light fragment (Z<=7) yield data in Au+Au reactions, measured by the EOS Collaboration at the LBNL Bevalac, are presented as a function of multiplicity. Moving from central to peripheral collisions the measured charge distributions develop progressively according to a power law which can be fitted, within errors, by a single tau exponent independently of the bombarding energy except for the data at 250A MeV. In addition, the location of the maximum in the individual yields of different charged fragments, for a given beam energy, shifts towards lower multiplicity as the fragment charge increases from Z = 3 to Z = 7. This trend is common to all six measured beam energies. Moments of charge distribution are also reported. The universal features observed in the present Au + Au data are consistent with previous experimental findings in the Au + C multifragmentation reaction at 1A GeV.

A least-squares approach to depth determination from second derivative gravity anomalies due to two-dimensional faulted and folded structures with application to the Gulf of Suez region, Egypt  

NASA Astrophysics Data System (ADS)

The present work confirms the basic ideas of Gupta [1983 Geophysics48, 357-360] and Abdelrahman et al. [1985 Geophysics50, 262-263] on the effectiveness of the least-squares method in determining depths to a vertical step (thin plate approximation) and a horizontal cylinder from the second vertical derivative maps by finding a solution of a non-linear equation in the form of f( z) = 0. Analysis of the second vertical derivative anomaly map in an area of the Gulf of Suez region of Egypt by this present approach revealed a depth to the center of a long NW-SE trending salt body approximated by a horizontal cylinder to be in a very good agreement with that obtained from seismic depth maps.

Fabrication and temperature-dependent magnetic properties of one-dimensional multilayer Au–Ni–Au–Ni–Au nanowires  

SciTech Connect

Multilayer Au–Ni–Au–Ni–Au nanowires with a controlled diameter of ?100 nm were synthesized by electrochemical deposition in porous alumina templates. The length of each Ni-segment was controlled up to ?230 nm, while the length of the Au segment sandwiched between two Ni segments was ?180 nm. X-ray diffraction patterns and energy-dispersive X-ray spectra confirmed the formation of purely crystalline nanowires. The magnetic properties of the multilayer Au–Ni–Au–Ni–Au nanowires were investigated in the temperature range 2–300 K. Room-temperature magnetic hysteresis confirmed the ferromagnetic nature of the nanowires. The plot of coercivity as a function of temperature (from 2 to 300 K) followed law applicable for ferromagnetic nanostructures. The magnetization tended to increase as the temperature decreased, following the modified Bloch's law similar to ferromagnetic nanoparticles. - Graphical abstract: (a) SEM image of Au–Ni–Au–Ni–Au nanowire with 230 nm Ni segment length and 180 nm Au sandwiched between Ni segments (b) Kneller's law (c) Bloch's law Display Omitted - Highlights: • Electrochemical fabrication of Au–Ni–Au–Ni–Au nanowires in alumina templates. • Formation of beadlike structure of Ni segments. • Coercivity versus T follows Kneller's law for ferromagnetic materials. • Magnetization as a function of temperature follows the modified Bloch's law.

Suppression of ? production in d +Au and Au+Au collisions at ?{sNN}=200 GeV  

NASA Astrophysics Data System (ADS)

We report measurements of ? meson production in p + p, d +Au, and Au +Au collisions using the STAR detector at RHIC. We compare the ? yield to the measured cross section in p + p collisions in order to quantify any modifications of the yield in cold nuclear matter using d +Au data and in hot nuclear matter using Au +Au data separated into three centrality classes. Our p + p measurement is based on three times the statistics of our previous result. We obtain a nuclear modification factor for ? (1 S + 2 S + 3 S) in the rapidity range | y | < 1 in d +Au collisions of RdAu = 0.79 ± 0.24 (stat.) ± 0.03 (syst.) ± 0.10 (p + p syst.). A comparison with models including shadowing and initial state parton energy loss indicates the presence of additional cold-nuclear matter suppression. Similarly, in the top 10% most-central Au +Au collisions, we measure a nuclear modification factor of RAA = 0.49 ± 0.1 (stat.) ± 0.02 (syst.) ± 0.06 (p + psyst.), which is a larger suppression factor than that seen in cold nuclear matter. Our results are consistent with complete suppression of excited-state ? mesons in Au +Au collisions. The additional suppression in Au +Au is consistent with the level expected in model calculations that include the presence of a hot, deconfined Quark-Gluon Plasma. However, understanding the suppression seen in d +Au is still needed before any definitive statements about the nature of the suppression in Au +Au can be made.

The Electromagnetic Cavity Resonant Absorption Properties of Au2S/Au Nanoshell  

NASA Astrophysics Data System (ADS)

: The Au2S/Au nanoshell consists of a nanometer-scale Au2S dielectric core surrounded by a thin Au metallic shell, and it is also called gold nanoshell. In this paper, the Au2S/Au nanoshell is regarded as a mini electromagnetic resonant cavity, the classical electrodynamics theory is used to treat with this Au2S/Au mini nanoshell cavity, and the cavity resonant wavelength is obtained. The cavity resonant absorption of Au2S/Au nanoshell shows a tunability controlled by the radii of the Au2S core. The radii of the Au2S core varies from 20 to 20 0nm, yielding a notable main mode (H101) cavity resonant absorption peak which is tunable from 100 to 1000nm. For the thickness of the gold shell is thin (about 2 nm), the coupling way of this Au2S/Au mini cavity is quite far from the conventional way. It is electromagnetic wave transmission coupling, and the thickness of the gold shell dominates the resonant energy and the linewidths of the absorption peak. In addition, the dielectric sphere resonance is discussed when the gold shell is thin and can be ignored. Key words: Au2S/Au nanoshell, cavity resonance, transmission coupling, resonant wavelength, absorption energy, gold film, skin effect, dielectric sphere resonance PACS No. [ 42.60.Da , 81.05.Ys , 84.40.Ba

A sensitive SERS substrate based on Au/TiO2/Au nanosheets.  

PubMed

Sensitive SERS substrates based on Au/TiO2/Au nanosheet have been prepared by physically sputtering Au nanoparticles onto fabricated TiO2 nanosheets. The Au/TiO2/Au nanosheets show much stronger SERS signal as compared to normal Au/Ti substrates by increasing surface area and effectively inducing plasmonic coupling between adjoining Au nanoparticles. In addition, influence factors such as concentration of probe solution and deposition time of gold nanoparticles were discussed. This study provides an easy-prepared and label-free substrate for the detection of biomolecule. PMID:25699693

Jet fragmentation in STAR going from p+p to Au+Au  

E-print Network

Jet fragmentation functions provide insight into jet structure and are expected to be modified by the nuclear medium in A+A collisions with respect to p+p reference measurements. If jet reconstruction is unbiased then a softening of the fragmentation functions is expected and should be observed in Au+Au collisions at RHIC. In these proceedings we present measurements of fragmentation functions in p+p for charged particles for different jet finding algorithms; these measurements are understood and therefore can be used as a reference for comparison with Au+Au results. We report the effect of background and its fluctuations on jet reconstruction in Au+Au collisions, estimated by using the jet algorithms on simulated Pythia jets embedded in real Au+Au events. Finally, measurements of fragmentation functions for jets reconstructed in Au+Au events and their comparison to the p+p baseline are presented and discussed.

Ferromagnetism of polythiophene-capped Au nanoparticles  

NASA Astrophysics Data System (ADS)

The magnetic and electrical transport properties of regioregular poly(3-hexylthiophene)-capped Au nanoparticles (NPs) doped with iodine have been investigated to clarify the effectiveness of conductive polymer capping on the induction of ferromagnetism in Au. The room-temperature magnetization curve of the undoped polythiophene-capped Au NPs exhibits a clear hysteresis behavior with a coercive force of 160 Oe. The spontaneous magnetization normalized by the mass of Au is 2.0 × 10-2 emu/g. The spontaneous magnetization was found virtually unaffected by iodine doping, whereas the electrical conductivity is enhanced dramatically to ˜10 S/cm. Our results show that polythiophene capping could lead to spontaneous magnetic polarization in Au NPs, and the conductivity of the polymer capping does not affect the ferromagnetism of the Au nanoparticles, opening a possibility for further investigation into the magnetotransport behavior of ferromagnetic Au NPs.

Systematics of Identified Particle Production in pp, dAu and Au-Au Collisions at RHIC Energies  

E-print Network

(Abstract is abridged for arXiv.) Identified mid-rapidity particle spectra and freeze-out properties are presented for 200 GeV pp, 200 GeV dAu and 62.4 GeV Au-Au collisions, measured in the STAR-TPC. Evolution of the identified particle spectra ($\\pi^{\\pm}$, $K^{\\pm}$, p and $\\overline{p}$) with charged particle multiplicity and event centrality is investigated in detail. Thermal model fits to the measured particle ratios yield a chemical freeze-out temperature $\\sim$ 155 MeV in 200 GeV pp, 200 GeV dAu and 62.4 GeV Au-Au collisions. The extracted chemical freeze-out temperature is close to the critical phase transition temperature predicted by lattice QCD calculations. The kinetic freeze-out temperature extracted from hydrodynamically motivated blast-wave models shows a continuous drop from pp, dAu and peripheral to central Au-Au collisions, while the transverse flow velocity increases from $\\sim$ 0.2 in pp to $\\sim$ 0.6 in central 200 GeV Au-Au collisions. The kinetic freeze-out parameters in 62.4 GeV and 200 GeV Au-Au collisions seem to be governed only by event multiplicity/centrality. In order to study the effect of resonance decays on the kinetic freeze-out parameters, the data are fitted with the blast-wave model including resonances. It is found that the thus extracted parameters are consistent with those obtained without including resonances, the resonance decays do not modify the spectral shapes significantly in the measured $p_{T}$ region in STAR.

Direct photons from Au+Au collisions at RHIC: QGP vs. hot hadronic gas  

E-print Network

We have analysed the preliminary PHENIX data on the transverse momentum distribution of direct photons in 0-20% centrality Au+Au collisions at $\\sqrt{s_{NN}}$=200 GeV. In ideal hydrodynamics, data are explained if Au+Au collision produces Quark-Gluon-Plasma at the temperature $T_i$=400 MeV, at an initial time $\\tau_i$=0.6 fm. PHENIX data are not explained in the alternate scenario when Au+Au collisions produces hot hadronic gas with initial temperature within physically acceptable limit.

Global polarization measurement in Au+Au collisions  

NASA Astrophysics Data System (ADS)

The system created in noncentral relativistic nucleus-nucleus collisions possesses large orbital angular momentum. Because of spin-orbit coupling, particles produced in such a system could become globally polarized along the direction of the system angular momentum. We present the results of ? and ?¯ hyperon global polarization measurements in Au+Au collisions at sNN=62.4 and 200 GeV performed with the STAR detector at the BNL Relativistic Heavy Ion Collider (RHIC). The observed global polarization of ? and ?¯ hyperons in the STAR acceptance is consistent with zero within the precision of the measurements. The obtained upper limit, |P?,?¯|?0.02, is compared with the theoretical values discussed recently in the literature.

Global polarization measurement in Au+Au collisions  

SciTech Connect

The system created in non-central relativisticnucleus-nucleus collisions possesses large orbital angular momentum. Dueto spin-orbit coupling, particles produced in such a system could becomeglobally polarized along the direction of the system angular momentum. Wepresent the results of Lambda and anti-Lambda hyperon global polarizationmeasurements in Au+Au collisions at sqrt sNN=62.4 GeV and 200 GeVperformed with the STAR detector at RHIC. The observed globalpolarization of Lambda and anti-Lambda hyperons in the STAR acceptance isconsistent with zero within the precision of the measurements. Theobtained upper limit, lbar P Lambda, anti-Lambda rbar<= 0.02, iscompared to the theoretical values discussed recently in theliterature.

Les sepsis intra-abdominaux diffus post-operatoires: aspects épidémiologiques, diagnostiques et thérapeutiques au Service de Chirurgie Générale du CHU Aristide Le Dantec de Dakar  

PubMed Central

Les sepsis intra-abdominaux diffus postopératoires (SIADPO) ont encore une fréquence alarmante. Ils mettent rapidement en cause l'intégrité des grandes fonctions. Le but de cette étude était d’évaluer leur prise en charge. Il s'agissait d'une étude rétrospective descriptive sur 10 ans (janvier 2000 à décembre 2009) portant sur 45 cas de SIADPO. Nous avons étudié les aspects épidémiologiques, diagnostiques, thérapeutiques et pronostiques. Il s'agissait de 45 cas dont 25 hommes et 20 femmes avec un sex-ratio de 1,25. L’âge moyen des patients était de 34 ans avec des extrêmes de 20 et 70 ans. Le SIADPO survenait au décours d'une intervention septique en urgence dans 68,8% des cas. Le délai moyen de diagnostic était de 10 jours. Les signes cliniques étaient dominés par les troubles du transit (80%), la douleur abdominale (77,7%), la fièvre (66,7%), le météorisme abdominal (33%). Une hyperleucocytose a été retrouvée dans 60% des cas. Le liquide intra-abdominal était polymicrobien. Tous les patients ont bénéficié d'une laparotomie xipho-pubienne dans les 72 heures. Nous avons noté 82,2% de péritonites secondaires notamment post-opératoires et 17,8% de péritonites persistantes. Les étiologies étaient dominées par le lâchage de suture digestive ou gynécologique (66,7% des cas). La stomie digestive a été le geste le plus fréquemment réalisé (41%). La guérison est survenue chez 75,5%. La morbidité opératoire était de 42% faite de suppuration pariétale (10 cas), de fistule entérocutanée (6 cas), d’éviscération (2 cas). La mortalité était de 24,5% en rapport avec le retard diagnostique et les défaillances multi-viscérales. Les interventions septiques en urgence sont les plus grandes pourvoyeuses de SIADPO. La mortalité reste encore élevée en rapport avec la défaillance viscérale. La précocité du diagnostic et de la réintervention conditionnent ainsi le pronostic. PMID:25161748

? production in p + p, Au + Au and U + U collisions at STAR  

NASA Astrophysics Data System (ADS)

We report STAR's high precision measurements on ? production at mid-rapidity from ?{ s} = 200 GeV p + p, central ?{sNN} = 200 GeV Au + Au , and central ?{sNN} = 193 GeV U + U collisions. With the significantly reduced uncertainty in p + p reference, we observe that the ? enhancement factors at RHIC are in between SPS and LHC, while enhancement factors are systematically larger in central U + U collisions than in central Au + Au collisions. The ?RAA is much larger than protons and pions for pT up to 4 GeV/c in central Au + Au collisions. The ratio of ?RAA in central U + U to that in central Au + Au collisions is above unity for pT up to 6 GeV/c, which indicates coalescence/recombination to be the dominant production mechanism for ? in these collisions for the measured pT range.

Nuclear modification and elliptic flow measurements for $?$ mesons at $\\sqrt{s_{NN}}$ = 200 GeV d+Au and Au+Au collisions by PHENIX  

E-print Network

We report the first results of the nuclear modification factors and elliptic flow of the phi mesons measured by the PHENIX experiment at RHIC in high luminosity Au+Au collisions at sqrt(sNN) = 200 GeV. The nuclear modification factors R_AA and R_CP of the phi follow the same trend of suppression as pi0's in Au+Au collisions. In d+Au collisions at sqrt(sNN) = 200 GeV, the phi mesons are not suppressed. The elliptic flow of the phi mesons, measured in the minimum bias Au+Au events, is statistically consistent with other identified particles.

Au microstructure and the functional properties of Ni/Au finishes on ceramic IC packages  

SciTech Connect

Ni/Au plated finishes used on thick-film metallized multilayer ceramic packages for integrated circuits must meet functional requirements such as bondability, sealability, and solderability. Their ability to do so is dependent, among other things, on the ability of the Au deposit to inhibit the grain boundary diffusion and subsequent surface oxidation of Ni. In this study, the relation between functional performance, Ni diffusionr ate, and Au microstructure was examined. Extent of Ni diffusion during heating was determined by Auger electron spectroscopy for several electrolytic and electroless Ni/Au finishing processes. Results were correlated with differences in Au microstructures determined by SEM, atomic force microscopy, and XRD.

Experimental evidence for electron localization on Au upon photo-activation of Au/anatase catalysts.  

PubMed

Time resolved microwave conductivity (TRMC) measurements show that the presence of Au on anatase Hombikat UV100 significantly reduces the lifetime of mobile electrons formed by photo-excitation of this photocatalyst at 300 nm, providing evidence for the widely acclaimed electron localization effect of Au in promoting TiO(2) photocatalysts. Electron localization efficiency of Au was even higher for Au-promoted Hombikat calcined at 400 degrees C, explained by enlargement of the anatase particle size and the associated, relatively larger fraction of anatase particles in direct contact with Au.

Synthesis and Optical Responses of Ag@Au/Ag@Au Double Shells  

NASA Astrophysics Data System (ADS)

We synthesize hollow-structured Ag@Au nanoparticles with single porous shell and Ag@Au/Ag@Au double shells by using the galvanic replacement reaction and investigate their linear and nonlinear optical properties. Our results show that the surface plasmon resonance wavelength of the hollow porous nanoparticles could be easily tuned in a wide range in the visible and near infrared region by controlling the volume of HAuCl4. The nonlinear optical refraction of the double-shelled Ag@Au/Ag@Au nanoparticles is prominently enhanced by the plasmon resonance. Our findings may find applications in biosensors and nonlinear optical nanodevices.

Systematic measurements of identified particle spectra in pp, d plus Au, and Au plus Au collisions at the STAR detector  

E-print Network

chamber are reported for pp and d + Au collisions at root s(NN) = 200 GeV and for Au + Au collisions at 62.4, 130, and 200 GeV. Average transverse momenta, total particle production, particle yield ratios, strangeness, and baryon production rates...the effect is more prominent for more central collisions. The extracted average transverse momentum of each particle species follows a trend determined by the total charged-particle multiplicity density. The Bjorken energy density estimate is at least several GeV/fm(3) for a formation time less than 1 fm/c. A significantly larger net-baryon density and a stronger increase of the net-baryon density with centrality are found in Au + Au collisions at 62.4 GeV than at the two higher energies. Antibaryon production relative to total particle multiplicity is found to be constant over centrality, but increases with the collision energy. Strangeness production relative to total particle multiplicity is similar at the three measured RHIC energies. Relative strangeness production increases quickly with centrality in peripheral Au + Au collisions, to a value about 50% above the pp value, and remains rather constant in more central collisions. Bulk freeze-out properties are extracted from thermal equilibrium model and hydrodynamics-motivated blast-wave model fits to the data. Resonance decays are found to have little effect on the extracted kinetic freeze-out parameters because of the transverse momentum range of our measurements. The extracted chemical freeze-out temperature is constant, independent of collision system or centrality...its value is close to the predicted phase-transition temperature, suggesting that chemical freeze-out happens in the vicinity of hadronization and the chemical freeze-out temperature is universal despite the vastly different initial conditions in the collision systems. The extracted kinetic freeze-out temperature, while similar to the chemical freeze-out temperature in pp, d + Au, and peripheral Au + Au collisions, drops significantly with centrality in Au + Au collisions, whereas the extracted transverse radial flow velocity increases rapidly with centrality. There appears to be a prolonged period of particle elastic scatterings from chemical to kinetic freeze-out in central Au + Au collisions. The bulk properties extracted at chemical and kinetic freeze-out are observed to evolve smoothly over the measured energy range, collision systems, and collision centralities....

Production of omega mesons in p + p, d + Au, Cu + Cu, and Au + Au collisions at sNN=200 GeV  

Microsoft Academic Search

The PHENIX experiment at the Relativistic Heavy Ion Collider has measured omega meson production via leptonic and hadronic decay channels in p+p, d+Au, Cu+Cu, and Au+Au collisions at sNN = 200 GeV. The invariant transverse momentum spectra measured in different decay modes give consistent results. Measurements in the hadronic decay channel in Cu+Cu and Au+Au collisions show that omega production

Heterostructured CIGS-Au nanoparticles: from Au-CIGS side-by-side structure to Au-core\\/CIGS-shell configuration  

Microsoft Academic Search

Heterostructured Au-Copper Indium Gallium Selenide (CIGS) nanoparticles (nps) with Au-CIGS side-by-side and Au-core\\/CIGS-shell configurations have been synthesized in a controllable manner using seed mediated growth. Detailed microstructure analysis reveals that (112) planes in the tetragonal chalcopyrite CIGS serve as the predominant termination surfaces during single phase CIGS nanoparticle growth. Preferential nucleation of Au on such planes determines the Au-CIGS side-by-side

Thermal and photoinduced reduction of ionic Au(III) to elemental Au nanoparticles by dissolved organic matter in water: possible source of naturally occurring Au nanoparticles.  

PubMed

Naturally occurring Au nanoparticles (AuNPs) have been widely observed in ore deposits, coal, soil, and environmental water. Identifying the source of these naturally occurring AuNPs could be helpful for not only the discovery of Au deposits through advanced exploration methods, but also the elucidation of the biogeochemical cycle and environmental toxicity of ionic Au and engineered AuNPs. Here, we investigated the effect of natural/simulated sunlight and heating on the reduction of ionic Au by ubiquitous dissolved organic matter (DOM) in river water. The reductive process probed by X-ray photoelectron spectroscopy revealed that phenolic, alcoholic, and aldehyde groups in DOM act as reductive sites. Long-time exposure with thermal and photoirradiation induced the further fusion and growth of AuNPs to branched Au nanostructure as precipitation. The formation processes and kinetics of AuNPs were further investigated using humic acid (HA) as the DOM model, with comprehensive characterizing methods. We have observed that HA can reduce ionic Au(III) complex (as chloride or hydroxyl complex) to elemental Au nanoparticles under sunlight or heating. In this process, nearly all of the Au(III) could be reduced to AuNPs, in which HA serves as not only the reductive agent, but also the coating agent to stabilize and disperse AuNPs. The size and stability of AuNPs were highly dependent on the concentration ratio of Au(III) to HA. These results imply that, besides biological processes, this thermal or photochemical reduction process is another possible source of naturally occurring AuNPs in natural environments, which possibly has critical impacts on the transport and transformation of Au and engineered AuNPs.

Suppression of Upsilon Production in d+Au and Au+Au Collisions at sqrt(s_NN) = 200 GeV  

E-print Network

We report measurements of Upsilon meson production in p+p, d+Au, and Au+Au collisions using the STAR detector at RHIC. We compare the Upsilon yield to the measured cross section in p+p collisions in order to quantify any modifications of the yield in cold nuclear matter using d+Au data and in hot nuclear matter using Au+Au data separated into three centrality classes. Our p+p measurement is based on three times the statistics of our previous result. We obtain a nuclear modification factor for Upsilon(1S+2S+3S) in the rapidity range |y|energy loss indicates the presence of additional cold-nuclear matter suppression. Similarly, in the top 10% most-central Au+Au collisions, we measure a nuclear modification factor of R_AA=0.49 +/- 0.1 (stat.) +/- 0.02 (sys.) +/- 0.06 (pp sys.), which is a larger suppression factor than that seen in cold nuclear matter. Our results are consistent with complete suppression of excited-state Upsilon mesons in Au+Au collisions. The additional suppression in Au+Au is consistent with the level expected in model calculations that include the presence of a hot, deconfined Quark-Gluon Plasma. However, understanding the suppression seen in d+Au is still needed before any definitive statements about the nature of the suppression in Au+Au can be made.

Synthesis of Au microwires by selective oxidation of Au-W thin-film composition spreads  

NASA Astrophysics Data System (ADS)

We report on the stress-induced growth of Au microwires out of a surrounding Au-W matrix by selective oxidation, in view of a possible application as ‘micro-Velcro’. The Au wires are extruded due to the high compressive stress in the tungsten oxide formed by oxidation of elemental W. The samples were fabricated as a thin-film materials library using combinatorial sputter deposition followed by thermal oxidation. Sizes and shapes of the Au microwires were investigated as a function of the W to Au ratio. The coherence length and stress state of the Au microwires were related to their shape and plastic deformation. Depending on the composition of the Au-W precursor, the oxidized samples showed regions with differently shaped Au microwires. The Au48W52 composition yielded wires with the maximum length to diameter ratio due to the high compressive stress in the tungsten oxide matrix. The values of wire length (35 ?m) and diameter (2 ?m) achieved at the Au48W52 composition are suitable for micro-Velcro applications.

Potential induced structural transformations of the Au(100) and Au(111) surfaces  

NASA Astrophysics Data System (ADS)

Work has concentrated on the use of emersed Au(111) films evaporated on cleaved mica, analogous to the Ag(111) films used in other GID studies. We have studied these Au(111) films using the dame LEEDUHV apparatus as in our previous studies of Au(111) crystals, and supplemented these with GID (grazing incidence X-ray diffraction) analysis of emersed Au(111) films with thru-air transfer to a two-circle diffractometer on beamline VI at SSRL. In-situ studies using GID with a new four-circle diffractometer on beamline VI at SSRL are scheduled for the spring running of SSRL. The ex-situ analyses by LEED and GID of the (1 x 1) yields (5 x 20) transformation were in reasonable agreement with one another, and the results qualitatively similar to the results for Au(100), i.e., the reconstructed (square root of 3 x 22) surface was observed only with emersion from K+ and Cs+ electrolytes, and not from pure acids, but the (square root of 3 x 22) was observed at much more anodic potentials of emersion than for the (100)-(5 x 20). Both of the reconstructions on Au(111) and (100) represent a contraction of the Au-Au bond length for the Au-Au bond length for the Au atoms in surface layer, 4 and 6.5 percent. Anions on the emersed surface stabilize the (1 x 1) structure and possibly cause an as yet unobserved expansion in the Au-Au surface atom bond length. Charge density waves (solitons) produced by ion (cation or anion) adsorption appear to be the driving force for the (111)-(1 x 1) reversible reaction beginning at the left (square root of 3 x 22) and (100)-(1 x 1) reversible reaction beginning at the left (5 x 20) surface phase transitions.

Comparative efficiencies of photothermal destruction of malignant cells using antibody-coated silica@Au nanoshells, hollow Au/Ag nanospheres and Au nanorods  

NASA Astrophysics Data System (ADS)

Three Au-based nanomaterials (silica@Au nanoshells, hollow Au/Ag nanospheres and Au nanorods) were evaluated for their comparative photothermal efficiencies at killing three types of malignant cells (A549 lung cancer cells, HeLa cervix cancer cells and TCC bladder cancer cells) using a CW NIR laser. Photodestructive efficiency was evaluated as a function of the number of nanoparticles required to destroy the cancer cells under 808 nm laser wavelength at fixed laser power. Of the three nanomaterials, silica@Au nanoshells needed the minimum number of particles to produce effective photodestruction, whereas Au nanorods needed the largest number of particles. Together with the calculated photothermal conversion efficiency, the photothermal efficiency rankings are silica@Au nanoshells > hollow Au/Ag nanospheres > Au nanorods. Additionally, we found that HeLa cells seem to present better heat tolerance than the other two cancer cell lines.

Anisotropic flow nu2 in Au + Au collisions at RHIC  

SciTech Connect

Using the RQMD model, transverse momentum dependence of the anisotropic flow v{sub 2} for {pi}, K, nucleon, {phi}, and {lambda}, are studied for Au + Au collisions at {radical}s{sub NN} = 200 GeV. Both hydrodynamic hadron-mass hiragracy (hhmh) at low p{sub T} region and particle type dependence (baryon versus meson) at the intermediate p{sub T} region are reproduced with the model calculations although the model underpredicted the overall values of v{sub 2} by a factor of 2-3. As expected, when the rescatterings are turned off, all v{sub 2} becomes zero. The failure of the hadronic model in predicting the absolute values of hadron v{sub 2} clearly demonstrate the need of early dense partonic interaction in heavy-ion collisions at RHIC. At the intermediate p{sub T}, the hadron type dependence cold also be explained by the vacume hadronic cross sections within the frame of the model. The measurements of collective motion of hadrons from high-energy nuclear collisions can provide information on the dynamical equation of state information of the system [1, 2, 3]. Specifically, the strange and multi-strange hadron flow results have demonstrated the partonic collectivity [5] and the heavy-flavor flow will test the hypothesis of early thermalization in such collisions [4]. At RHIC, the measurements [6, 7] of elliptic flow v{sub 2} and nuclear modification factor r{sub AA} has lead to the conclusion that hadrons were formed via the coalescence/recombination of massive quarks [8, 9, 10]. This finding is directly related to the key issue in high-energy nuclear collisions such as deconfinement and chiral symmetry restoration. In addition, it also touched the important problem of hadronization process in high-energy collisions. Therefore a systematic study with different approaches becomes necessary. In this report, using a hadronic transport model UrQMD(v2.2)/RQMD(v2.4) [11, 12], we study the v{sub 2} of {pi}, K, p, {phi}, and {Lambda} from Au + Au collisions at 200 GeV. Properties of centrality dependent and freeze-out time dependent will be discussed. We try to answer some specific questions like how much the observed features can be reproduced by the hadronic model and why. In this approach, the vacumme cross sections are used for strong interactions. Unlike the treatment in most hydrodynamic calculations, the transition from strong interaction and free-steaming is determined by the local density and gradual. As we will discuss in the paper, the shortcoming of this method is lack of the partonic interactions which is important for the early dynamics in ultra-relativistic heavy ion collisions [13]. In order to take care of both partonic and hadronic interactions in high-energy nuclear collisions, a combination of hydrodynamic model for early stage (the perfect fluid stage) and hadronic transport model for later stage and freeze-out has been tried [14, 15].

Relaxation equations for the shear stress tensor components, derived from the phenomenological Israel-Stewart's theory of dissipative relativistic fluid, are solved simultaneously with the energy-momentum conservation equations. Comparison of evolution of ideal and viscous fluid, both initialized under the similar conditions, e.g. same equilibration time, energy density and velocity profile, indicate that in viscous fluid, energy density or temperature of the fluid evolve slowly than in an ideal fluid. Transverse expansion is also more in viscous evolution. We have also studied particle production in viscous dynamics. Compared to ideal dynamics, in viscous dynamics, particle yield at high $p_T$ is increased. Elliptic flow on the other hand decreases. Minimally viscous QGP fluid, initialized at entropy density $s_{ini}$=110 $fm^{-3}$ at the initial time $\\tau_i$=0.6 fm, if freeze-out at temperature $T_F$=130 MeV, explains the centrality dependence of $p_T$ spectra of identified particles. Experimental $p_T$ spectra of $\\pi^-$, $K^+$ and protons in 0-5%, 5-10%, 10-20%, 20-30%, 30-40% and 40-50% Au+Au collisions are well reproduced through out the experimental $p_T$ range. This is in contrast to ideal dynamics, where, the spectra are reproduced only up to $p_T\\approx$1.5 GeV. Minimally viscous QGP fluid, also explain the elliptic flow in mid-central (10-20%, 16-23%, 20-30%) collisions. The minimum bias elliptic flow is also explained. However, the model under-predict/over-predict the elliptic flow in very central/peripheral collisions.

Au40: A Large Tetrahedral Magic Cluster  

SciTech Connect

40 is a magic number for tetrahedral symmetry predicted in both nuclear physics and the electronic jellium model. We show that Au{sub 40} could be such a magic cluster from density functional theory-based basin hopping for global minimization. The putative global minimum found for Au{sub 40} has a twisted pyramid structure, reminiscent of the famous tetrahedral Au{sub 20}, and a sizable HOMO-LUMO gap of 0.69 eV, indicating its molecular nature. Analysis of the electronic states reveals that the gap is related to shell closings of the metallic electrons in a tetrahedrally distorted effective potential.

A Study of Parton Energy Loss in Au+Au Collisions at RHIC using Transport Theory  

E-print Network

Parton energy loss in Au+Au collisions at RHIC energies is studied by numerically solving the relativistic Boltzmann equation for the partons including $2 \\leftrightarrow 2$ and $2 \\to 2 + final state radiation$ collision processes. Final particle spectra are obtained using two hadronization models; the Lund string fragmentation and independent fragmentation models. Recent, preliminary $\\pi^0$ transverse momentum distributions from central Au+Au collisions at RHIC are reproduced using gluon-gluon scattering cross sections of 5-12 mb, depending upon the hadronization model. Comparisons with the HIJING jet quenching algorithm are made.

Strangelet search in Au+Au collisions at sNN=200 GeV  

NASA Astrophysics Data System (ADS)

We have searched for strangelets in a triggered sample of 61 million central (top 4%) Au+Au collisions at sNN=200 GeV near beam rapidities at the STAR solenoidal tracker detector at the BNL Relativistic Heavy Ion Collider. We have sensitivity to metastable strangelets with lifetimes of order ?0.1 ns, in contrast to limits over ten times longer in BNL Alternating Gradient Synchrotron (AGS) studies and longer still at the CERN Super Proton Synchrotron (SPS). Upper limits of a few 10-6 to 10-7 per central Au+Au collision are set for strangelets with mass ?30 GeV/c2.

Radical-involved photosynthesis of AuCN oligomers from Au nanoparticles and acetonitrile.  

PubMed

We show here the first radical route for the direct photosynthesis of AuCN oligomers with different sizes and shapes, as evidenced by TEM observations, from an Au nanoparticle/benzaldehyde/CH(3)CN ternary system in air under UV-light irradiation. This photochemical route is green, mild, and universal, which makes itself distinguishable from the common cyanidation process. Several elementary reaction steps, including the strong C-C bond dissociation of CH(3)CN and subsequent •CN radical addition to Au, have been suggested to be critical in the formation of AuCN oligomers based on the identification of •CN radical by in situ EPR and the radical trapping technique, and other reaction products by GC-MS and (1)H NMR, and DFT calculations. The resulting solid-state AuCN oligomers exhibit unique spectroscopic characters that may be a result of the shorter Au-Au distances (namely, aurophilicity) and/or special polymer-like structures as compared with gold cyanide derivatives in the aqueous phase. The nanosized AuCN oligomers supported on mesoporous silica showed relatively good catalytic activity on the homogeneous annulation of salicylaldehyde with phenylacetylene to afford isoflavanones employing PBu(3) as the cocatalyst under moderate conditions, which also serves as evidence for the successful production of AuCN oligomers.

CO oxidation on Au/FePO(4) catalyst: Reaction pathways and nature of Au sites  

SciTech Connect

In situ FTIR spectroscopy coupled with downstream mass spectrometry has been used to clarify the pathways for room temperature (rt) CO oxidation over iron phosphate-supported Au catalyst. The charge state of Au on Au/FePO4 after calcination, reduction, or under reaction conditions was assessed by both FTIR spectroscopy (CO probing) and X-ray absorption near edge spectroscopy (XANES). Results from both approaches show that cationic gold species dominate the surface after pretreatment in O2 at 200 C. A portion of the cationic gold on Au/FePO4 can be reduced by the initial CO adsorption at rt, and subsequently repeated CO exposures do not reduce the remaining cationic Au. FTIR and Raman results from cycled CO reduction and O2 reoxidation of Au/FePO4 indicate that there are active structural oxygen species on the surface of Au/FePO4 that can be consumed by CO and then replenished by gaseous O2 at rt. Au activates both CO and O2 so that the FePO4 support can undergo reduction (by CO) and reoxidation (by O2) cycles. The results of COoxidation with labeled 18O2 suggest the operation of two parallel reactionpathways at rt: (1) a redox pathway in which FePO4 supplies active oxygen and (2) a direct pathway on metallic Au, via either Langmuir-Hinshelwood or Eley-Rideal mechanism, in which gas phase O2 provides the active oxygen.

Ab initio study of thiolate-protected Au102 nanocluster.  

PubMed

A total structural determination of the Au(102)(p-MBA)(44) nanocluster has been recently achieved via successful crystallization of the thiolated-protected gold nanocluster (Jadzinsky et al. Science 2007, 318, 430). The embedded Au(102) cluster may be viewed as a multilayered structure described as Au(54)(penta-star)@Au(38)(ten wings)@Au(10)(two pentagon caps), where the inner Au(54) "penta-star" consists of five twinned Au(20) tetrahedral subunits. To gain more insight into high stability of the Au(102)(p-MBA)(44) nanocluster, we have performed ab initio calculations to study electronic properties of a homologue Au(102)(SCH(3))(44) nanocluster, an Au(102)(SCH(3))(42) nanocluster (with two SCH(3) groups less), and an "effectively isoelectronic" Au(104)(SCH(3))(46) nanocluster with a more symmetric embedded Au(104) structure. Electronic structure calculations suggest that the Au(102)(SCH(3))(44) nanocluster possesses a reasonably large gap (approximately 0.54 eV) between the highest occupied molecular orbital and the lowest unoccupied molecular orbital (HOMO-LUMO gap), which is comparable to the measured HOMO-LUMO gap (approximately 0.65 eV) of the bare Au(58) cluster. Likewise, the Au(104)(SCH(3))(46) nanocluster has a HOMO-LUMO gap of approximately 0.51 eV, comparable to that of Au(102)(SCH(3))(44) nanocluster. In contrast, the Au(102)(SCH(3))(42) nanocluster has a zero HOMO-LUMO gap. These results confirm that high stability of the Au(102)(p-MBA)(44) nanocluster may be attributed in part to the electronic shell closing of effective 58 (= 102 - 44) valence electrons, as in the case of Au(25)(SCH(2)CH(2)Ph)(18)(-) cluster whose high stability may be attributed to the electronic shell closing of effective 8 (= 26 -18) valence electrons.

Comparison of the space-time extent of the emission source in d +Au and Au + Au collisions at ?{sNN} = 200 GeV  

NASA Astrophysics Data System (ADS)

Two-pion interferometry measurements in d +Au and Au +Au collisions at ?{sNN} = 200 GeV are used to extract and compare the Gaussian source radii Rout, Rside and Rlong, which characterize the space-time extent of the emission sources. The comparisons, which are performed as a function of collision centrality and the mean transverse momentum for pion pairs, indicate strikingly similar patterns for the d + Au and Au + Au systems. They also indicate a linear dependence of Rside on the initial transverse geometric size R bar , as well as a smaller freeze-out size for the d + Au system. These patterns point to the important role of final-state re-scattering effects in the reaction dynamics of d + Au collisions.

LaAu2 and CeAu2 surface intermetallic compounds grown by high-temperature deposition on Au(111)  

NASA Astrophysics Data System (ADS)

We report on the crystal structure and electronic bands of LaAu2 and CeAu2 surface intermetallic compounds grown by high-temperature deposition on Au(111). By scanning-tunneling microscopy we study the formation of different alloy phases as a function of growth temperature and lanthanide coverage. We determine the specific growth conditions to achieve monolayers and bilayers of LaAu2 and CeAu2 with high crystalline quality. Due to lattice mismatch with the underlying Au substrate, both LaAu2 and CeAu2 exhibit long-range moiré patterns, which can serve as templates for further nanostructure growth. By angle-resolved photoemission we map the two-dimensional band structure of these surface alloys, discussing the nature of the different spectral features in the light of first-principles calculations.

Rho Meson Diffraction off Au Nuclei  

E-print Network

The STAR Ultra Peripheral Collisions program has collected a substantial sample of $\\rho$ mesons and for the first time at RHIC energies it has been able to extract the distribution of momentum transfer t from diffractive elastic scattering off the Au ion. The resulting diffraction pattern is consistent with coherent scattering off a nuclear object the size of the Au nuclei. Measurements of this nature can offer insights and guidance to the ongoing preparations for the new electron ion programs.

The role of plasmons and interband transitions in the color of AuAl2, AuIn2, and AuGa2  

NASA Astrophysics Data System (ADS)

First principles calculations of the optical properties of the intermetallic compounds AuAl2, AuIn2, and AuGa2 have been performed. Analysis of the dielectric functions showed that AuAl2 is unique because a bulk plasmon is seen in the optical region and contributes to the purple color of this material. An experimental electron energy-loss spectrum showed excellent agreement with the theoretical prediction and confirmed the presence of the bulk plasmon.

Systematic Measurements of Identified Particle Spectra in pp, d+Au and Au+Au Collisions from STAR  

SciTech Connect

Identified charged particle spectra of {pi}{sup {+-}}, K{sup {+-}}, p and {bar p} at mid-rapidity (|y| < 0.1) measured by the dE/dx method in the STAR-TPC are reported for pp and d + Au collisions at {radical}s{sub NN} = 200 GeV and for Au + Au collisions at 62.4 GeV, 130 GeV, and 200 GeV. Average transverse momenta, total particle production, particle yield ratios, strangeness and baryon production rates are investigated as a function of the collision system and centrality. The transverse momentum spectra are found to be flatter for heavy particles than for light particles in all collision systems; the effect is more prominent for more central collisions. The extracted average transverse momentum of each particle species follows a trend determined by the total charged particle multiplicity density. The Bjorken energy density estimate is at least several GeV/fm{sub 3} for a formation time less than 1 fm/c. A significantly larger net-baryon density and a stronger increase of the net-baryon density with centrality are found in Au + Au collisions at 62.4 GeV than at the two higher energies. Antibaryon production relative to total particle multiplicity is found to be constant over centrality, but increases with the collision energy. Strangeness production relative to total particle multiplicity is similar at the three measured RHIC energies. Relative strangeness production increases quickly with centrality in peripheral Au + Au collisions, to a value about 50% above the pp value, and remains rather constant in more central collisions. Bulk freeze-out properties are extracted from thermal equilibrium model and hydrodynamics-motivated blast-wave model fits to the data. Resonance decays are found to have little effect on the extracted kinetic freeze-out parameters due to the transverse momentum range of our measurements. The extracted chemical freeze-out temperature is constant, independent of collision system or centrality; its value is close to the predicted phase-transition temperature, suggesting that chemical freeze-out happens in the vicinity of hadronization and the chemical freezeout temperature is universal despite the vastly different initial conditions in the collision systems. The extracted kinetic freeze-out temperature, while similar to the chemical freeze-out temperature in pp, d + Au, and peripheral Au + Au collisions, drops significantly with centrality in Au + Au collisions, whereas the extracted transverse radial flow velocity increases rapidly with centrality. There appears to be a prolonged period of particle elastic scatterings from chemical to kinetic freeze-out in central Au + Au collisions. The bulk properties extracted at chemical and kinetic freeze-out are observed to evolve smoothly over the measured energy range, collision systems, and collision centralities.

Identified charged-particle spectra of ?±, K±, p, and pmacr at midrapidity (|y|<0.1) measured by the dE/dx method in the STAR (solenoidal tracker at the BNL Relativistic Heavy Ion Collider) time projection chamber are reported for pp and d+Au collisions at sNN=200 GeV and for Au+Au collisions at 62.4, 130, and 200 GeV.

Spectra and ratios of identified particles in Au+Au and d+Au collisions at sNN=200 GeV  

NASA Astrophysics Data System (ADS)

The transverse momentum (pT) spectra and ratios of identified charged hadrons (?±, K±, p, p¯) produced in sNN=200 GeV Au+Au and d+Au collisions are reported in five different centrality classes for each collision species. The measurements of pions and protons are reported up to pT=6 GeV/c (5 GeV/c), and the measurements of kaons are reported up to pT=4 GeV/c (3.5 GeV/c) in Au+Au (d+Au) collisions. In the intermediate pT region, between 2 and 5 GeV/c, a significant enhancement of baryon-to-meson ratios compared to those measured in p+p collisions is observed. This enhancement is present in both Au+Au and d+Au collisions and increases as the collisions become more central. We compare a class of peripheral Au+Au collisions with a class of central d+Au collisions which have a comparable number of participating nucleons and binary nucleon-nucleon collisions. The pT-dependent particle ratios for these classes display a remarkable similarity, which is then discussed.

Spectra and ratios of identified particles in Au+Au and d+Au collisions at sqrt(s_NN)=200 GeV  

E-print Network

The transverse momentum (p_T) spectra and ratios of identified charged hadrons (\\pi^+/-, K^+/-, p, p^bar) produced in sqrt(s_NN)=200 GeV Au+Au and d+Au collisions are reported in five different centrality classes for each collision species. The measurements of pions and protons are reported up to p_T=6 GeV/c (5 GeV/c), and the measurements of kaons are reported up to p_T=4 GeV/c (3.5 GeV/c) in Au+Au (d+Au) collisions. In the intermediate p_T region, between 2--5 GeV/c, a significant enhancement of baryon to meson ratios compared to those measured in p+p collisions is observed. This enhancement is present in both Au+Au and d+Au collisions, and increases as the collisions become more central. We compare a class of peripheral Au+Au collisions with a class of central d+Au collisions which have a comparable number of participating nucleons and binary nucleon-nucleon collisions. The p_T dependent particle ratios for these classes display a remarkable similarity, which is then discussed.

Multifragment events resulting from peripheral Au + Au collisions at 35 MeV/nucleon are analysed in terms of critical behavior. The analysis of most of criticality signals proposed so far (conditional moments of charge distributions, Campi scatter plot, fluctuations of the size of the largest fragment, intermittency analysis) is consistent with the occurrence of a critical behavior of the system.

In these composites the atomic Au clusters with even number of atoms exhibit higher catalytic activity for electrochemical oxidation of n-propanol in 1 M NaOH than the odd-number atoms clusters. Also, infrared spectroscopy shows that even numbered PANI/AuN composites affect the N-H stretching vibration more strongly than the corresponding odd numbered ones. This behavior matches the theoretically predicted variations of HOMO-LUMO gap energy and the stability of the atomic Au clusters. It also agrees with the earlier experimental work in which the UPS spectra of isolated, mass-selected Au clusters have been reported.

Wafer-level Au-Au bonding in the 350-450 °C temperature range  

NASA Astrophysics Data System (ADS)

Metal thermocompression bonding is a hermetic wafer-level packaging technology that facilitates vertical integration and shrinks the area used for device sealing. In this paper, Au-Au bonding at 350, 400 and 450 °C has been investigated, bonding wafers with 1 µm Au on top of 200 nm TiW. Test Si laminates with device sealing frames of 100, 200, and 400 µm in width were realized. Bond strengths measured by pull tests ranged from 8 to 102 MPa and showed that the bond strength increased with higher bonding temperatures and decreased with increasing frame width. Effects of eutectic reactions, grain growth in the Au film and stress relaxation causing buckles in the TiW film were most pronounced at 450 °C and negligible at 350 °C. Bond temperature below the Au-Si eutectic temperature 363 °C is recommended.

Adsorbate-modified Electron Relaxation in Au-Au_2S Nanoshells  

NASA Astrophysics Data System (ADS)

Au-Au_2S nanoshells are 50 nm nanoparticles consisting of an Au_2S core encapsulated by a thin (<5 nm) Au shell. Their optical properties are determined by the metallic shell layer, whose inner and outer radii control plasmon frequency and whose thickness determines plasmon linewidth[1]. We studied the time-resolved relaxation of hot electrons in the Au shell, using degenerate pump-probe spectroscopy. The electron relaxation for nanoshells in solution was appreciably slower than relaxation for bulk gold, moreover, adsorbed molecules on the nanoshell surface strongly modify this relaxation. Density functional theory calculations indicate that the molecules providing the strongest modification of relaxation possess the largest induced dipole moments above a metal surface, indicating that the adsorbate-induced perturbation of the nanoshell electron dynamics appears to be primarily electronic in nature.

Recent work has shown that a Au-Ni-Sn ternary compound with a nominal composition of Au0.5Ni0.5Sn4 redeposits and grows at the interface between eutectic Pb-Sn solder and Ni\\/Au metallization during aging at 150°C. The present work verifies the existence of the Au0.5Ni0.5Sn4 phase by examining the Sn-rich corner of the Au-Ni-Sn ternary phase diagram. The reconfiguration mechanism of the AuSn4 from

Revisiting the S-Au(111) interaction: Static or Dynamic?  

SciTech Connect

The chemical inertness typically observed for Au does not imply a general inability to form stable bonds with non-metals but is rather a consequence of high reaction barriers. The Au-S interaction is probably the most intensively studied interaction of Au surfaces with non-metals as, for example, it plays an important role in Au ore formation, and controls the structure and dynamics of thiol-based self-assembled-monolayers (SAMs). In recent years a quite complex picture of the interaction of sulfur with Au(111) surfaces emerged, and a variety of S-induced surface structures was reported under different conditions. The majority of these structures were interpreted in terms of a static Au surface, where the positions of the Au atoms remain essentially unperturbed. Here we demonstrate that the Au(111) surface exhibits a very dynamic character upon interaction with adsorbed sulfur: low sulfur coverages modify the surface stress of the Au surface leading to lateral expansion of the surface layer; large-scale surface restructuring and incorporation of Au atoms into a growing two-dimensional AuS phase were observed with increasing sulfur coverage. These results provide new insight into the Au-S surface chemistry, and reveal the dynamic character of the Au(111) surface.

Production of ? mesons in p + p, d + Au, Cu + Cu, and Au + Au collisions at sNN=200 GeV  

NASA Astrophysics Data System (ADS)

The PHENIX experiment at the Relativistic Heavy Ion Collider has measured ? meson production via leptonic and hadronic decay channels in p+p, d+Au, Cu+Cu, and Au+Au collisions at sNN = 200 GeV. The invariant transverse momentum spectra measured in different decay modes give consistent results. Measurements in the hadronic decay channel in Cu+Cu and Au+Au collisions show that ? production has a suppression pattern at high transverse momentum, similar to that of ?0 and ? in central collisions, but no suppression is observed in peripheral collisions. The nuclear modification factors, RAA, are consistent in Cu+Cu and Au+Au collisions at similar numbers of participant nucleons.

Introduction Notre étude consistera à rapporter les indications et les lésions objectivées à la fibroscopie digestive haute et relever les particularités selon le sexe. Méthodes Étude rétrospective, descriptive sur des résultats de compte-rendu de la fibroscopie digestive haute menée en unité d'endoscopie digestive du service d'hépato-gastro-entérologie du CHU Campus de Lomé du 15 Mai 2009 au 31 Décembre 2013. Résultats La fibroscopie digestive haute a été réalisée chez 2795 patients dont 1188 hommes et 1607 femmes. L’âge moyen était de 40,65 ans (Extrêmes: 5 et 93 ans). La fibroscopie digestive haute était normale chez les femmes que chez les hommes avec une différence statistiquement significative (p = 0,000). Les principales indications étaient: les épigastralgies chez les femmes (p = 0,000); les hémorragies digestives hautes (p = 0,000) et l'hypertension portale (p = 0,000) chez les hommes; 3485 lésions pathologiques ont été observées. La pathologie inflammatoire prédominait (56,3%), la pathologie ulcéreuse (13,89%), la pathologie tumorale (2,01%). Les varices et la candidose œsophagiennes étaient significativement notées chez les hommes. Les ulcérations gastriques (p = 0,000), le reflux biliaire duodéno-gastrique (p = 0,017) étaient plus retrouvés chez les femmes et la gastropathie hypertensive beaucoup plus chez les hommes (p = 0,000). Que les lésions duodénales soient inflammatoires ou ulcéreuses associées ou non à une sténose bulbaire, elles étaient plus fréquentes chez les hommes. Conclusion De manière générale, il y avait une prédominance des lésions inflammatoires chez les femmes, les lésions tumorales et ulcéreuses chez les hommes

CO Oxidation on Au/FePO4 Catalyst: Reaction Pathways and Nature of Au Sites  

SciTech Connect

In situ FTIR spectroscopy coupled with downstream mass spectrometry has been used to clarify the pathways for room temperature (rt) CO oxidation over iron phosphate-supported Au catalyst. The charge state of Au on Au/FePO{sub 4} after calcination, reduction, or under reaction conditions was assessed by both FTIR spectroscopy (CO probing) and X-ray absorption near edge spectroscopy (XANES). Results from both approaches show that cationic gold species dominate the surface after pretreatment in O{sub 2} at 200 C. A portion of the cationic gold on Au/FePO{sub 4} can be reduced by the initial CO adsorption at rt, and subsequently repeated CO exposures do not reduce the remaining cationic Au. FTIR and Raman results from cycled CO reduction and O{sub 2} reoxidation of Au/FePO{sub 4} indicate that there are active structural oxygen species on the surface of Au/FePO4that can be consumed by CO and then replenished by gaseous O{sub 2} at rt. Au activates both CO and O{sub 2} so that the FePO{sub 4} support can undergo reduction (by CO) and reoxidation (by O{sub 2}) cycles. The results of CO oxidation with labeled {sup 18}O{sub 2} suggest the operation of two parallel reaction pathways at rt: (1) a redox pathway in which FePO{sub 4} supplies active oxygen and (2) a direct pathway on metallic Au, via either Langmuir-Hinshelwood or Eley-Rideal mechanism, in which gas phase O{sub 2} provides the active oxygen.

Au nanoparticles films used in biological sensing  

NASA Astrophysics Data System (ADS)

Lactobacillus para paracasei are used commonly as functional food and probiotic substances. In this work Au nanoparticles self-assembled films were used for Lactobacillus para paracasei determination at five different concentrations. Functionalized substrates were immersed in a colloidal solution for one and a half hour at room temperature and dried at room temperature during four hours. After that, drops of Lactobacillus para paracasei in aqueous solution were put into the Au nanoparticles film and let dry at room temperature for another two hours. Infrared spectroscopy in attenuated total reflectance sampling mode was used to observe generation peaks due to substrate silanization, enhancement of Si-O band intensity due to the Au colloids added to silanized substrate and also to observe the enhancement of Lactobacillus para paracasei infrared intensity of the characteristic frequencies at 1650, 1534 and 1450 cm-1 due to surface enhancement infrared absorption.

d+Au Collisions at STAR  

E-print Network

STAR has measured forward pi^0 production in p+p and d+Au collisions at sqrt{s_{NN}}=200 GeV. The p+p yield generally agrees with NLO pQCD calculations. The d+Au yield is strongly suppressed at =4.0, well below shadowing expectations. Exploratory measurements of azimuthal correlations between forward pi^0 and mid-rapidity charged hadrons show a recoil peak in p+p that is suppressed in d+Au at low pion energy. These observations are qualitatively consistent with a saturation picture of the low-x gluon structure of heavy nuclei. Future measurements to elucidate the dynamics underlying these observations are also described.

Structure Determination of [Au18 (SR)14 ].  

PubMed

Unravelling the atomic structures of small gold clusters is the key to understanding the origin of metallic bonds and the nucleation of clusters from organometallic precursors. Herein we report the X-ray crystal structure of a charge-neutral [Au18 (SC6 H11 )14 ] cluster. This structure exhibits an unprecedented bi-octahedral (or hexagonal close packing) Au9 kernel protected by staple-like motifs including one tetramer, one dimer, and three monomers. Until the present, the [Au18 (SC6 H11 )14 ] cluster is the smallest crystallographically characterized gold cluster protected by thiolates and provides important insight into the structural evolution with size. Theoretical calculations indicate charge transfer from surface to kernel for the HOMO-LUMO transition. PMID:25619892

Using molecular-dynamics simulation, we study the sputtering of a Au (1 1 1) surface by Au n clusters ( n = 1-201) with impact energies between 0.16 and 64 keV/atom. We vary systematically both the total energy E and the cluster size n, such that the dependence of the sputter yield on these quantities can be discussed. As our basic result, we find the sputter yield Y to scale with the total energy E of the projectile. The sputter yield exhibits a polynomial increase, ? E1.6, up to a critical energy Ec ? 40 keV, which coincides roughly with the threshold energy for subcascade formation. Above Ec, the yield increases approximately linearly with E. These findings are discussed in the light of the considerable data base of Au sputtering which has been built up in recent years due both to experimental and simulational work.

Jet-Hadron Correlations in ?sNN =200 GeV p +p and Central Au +Au Collisions  

NASA Astrophysics Data System (ADS)

Azimuthal angular correlations of charged hadrons with respect to the axis of a reconstructed (trigger) jet in Au +Au and p +p collisions at ?sNN =200 GeV in STAR are presented. The trigger jet population in Au +Au collisions is biased toward jets that have not interacted with the medium, allowing easier matching of jet energies between Au +Au and p +p collisions while enhancing medium effects on the recoil jet. The associated hadron yield of the recoil jet is significantly suppressed at high transverse momentum (pTassoc) and enhanced at low pTassoc in 0%-20% central Au +Au collisions compared to p +p collisions, which is indicative of medium-induced parton energy loss in ultrarelativistic heavy-ion collisions.

Influence of Au and TiO2 structures on hydrogen dissociation over TiO2/Au(100)  

NASA Astrophysics Data System (ADS)

We performed H2-D2 exchange reactions over TiOx/Au(100) and compared the observed reaction kinetics with those reported for TiOx/Au(111) in order to clarify the influence of the Au and TiO2 structures on dissociation of H2 molecules. Low energy electron diffraction observations showed that the TiO2 produced on Au(100) was disordered, in contrast to the comparatively ordered TiO2 structure formed on Au(111). The activation energies and the turnover frequencies for HD formation over TiO2/Au(100) agreed well with those for TiO2/Au(111), clearly indicating that the hydrogen dissociation sites created over TiO2/Au(100) were the perimeter interface between stoichiometric TiO2 and Au, as was previously concluded for TiO2/Au(111). We concluded that the creation of active sites for hydrogen dissociation was independent of the Au and TiO2 structures consisting perimeter interface, and that local bonds that formed between Au and O atoms of stoichiometric TiO2 were essential for the creation of active sites.

Fabrication of segmented Au/Co/Au nanowires: insights in the quality of Co/Au junctions.  

PubMed

Electrodeposition is a versatile method, which enables the fabrication of a variety of wire-like nanoarchitectures such as nanowires, nanorods, and nanotubes. By means of template-assisted electrodeposition, segmented Au/Co/Au nanowires are grown in anodic aluminum oxide templates from two different electrolytes. To tailor the properties of the cobalt segments, several electrochemical conditions are studied as a function of current density, pulse deposition, and pH. The morphology, crystal structure, and magnetic properties are accordingly investigated. Changes in the deposition conditions affect the cobalt electrocrystallization process directly. Cobalt tends to crystallize mainly in the hexagonal close-packed structure, which is the reason cobalt might not accommodate satisfactorily on the face-centered cubic Au surface or vice versa. We demonstrate that by modifying the electrolyte and the applied current densities, changes in the texture and the crystalline structure of cobalt lead to a good quality connection between dissimilar segments. In particular, lowering the bath pH, or using pulse plating at a high overpotential, produces polycrystalline fcc Co and thus well-connected Co/Au bimetallic junctions with smooth interface. These are crucial factors to be carefully considered taking into account that nanowires are potential building blocks in micro- and nanoelectromechanical systems. PMID:25025496

AU-FREDI - AUTONOMOUS FREQUENCY DOMAIN IDENTIFICATION  

NASA Technical Reports Server (NTRS)

The Autonomous Frequency Domain Identification program, AU-FREDI, is a system of methods, algorithms and software that was developed for the identification of structural dynamic parameters and system transfer function characterization for control of large space platforms and flexible spacecraft. It was validated in the CALTECH/Jet Propulsion Laboratory's Large Spacecraft Control Laboratory. Due to the unique characteristics of this laboratory environment, and the environment-specific nature of many of the software's routines, AU-FREDI should be considered to be a collection of routines which can be modified and reassembled to suit system identification and control experiments on large flexible structures. The AU-FREDI software was originally designed to command plant excitation and handle subsequent input/output data transfer, and to conduct system identification based on the I/O data. Key features of the AU-FREDI methodology are as follows: 1. AU-FREDI has on-line digital filter design to support on-orbit optimal input design and data composition. 2. Data composition of experimental data in overlapping frequency bands overcomes finite actuator power constraints. 3. Recursive least squares sine-dwell estimation accurately handles digitized sinusoids and low frequency modes. 4. The system also includes automated estimation of model order using a product moment matrix. 5. A sample-data transfer function parametrization supports digital control design. 6. Minimum variance estimation is assured with a curve fitting algorithm with iterative reweighting. 7. Robust root solvers accurately factorize high order polynomials to determine frequency and damping estimates. 8. Output error characterization of model additive uncertainty supports robustness analysis. The research objectives associated with AU-FREDI were particularly useful in focusing the identification methodology for realistic on-orbit testing conditions. Rather than estimating the entire structure, as is typically done in ground structural testing, AU-FREDI identifies only the key transfer function parameters and uncertainty bounds that are necessary for on-line design and tuning of robust controllers. AU-FREDI's system identification algorithms are independent of the JPL-LSCL environment, and can easily be extracted and modified for use with input/output data files. The basic approach of AU-FREDI's system identification algorithms is to non-parametrically identify the sampled data in the frequency domain using either stochastic or sine-dwell input, and then to obtain a parametric model of the transfer function by curve-fitting techniques. A cross-spectral analysis of the output error is used to determine the additive uncertainty in the estimated transfer function. The nominal transfer function estimate and the estimate of the associated additive uncertainty can be used for robust control analysis and design. AU-FREDI's I/O data transfer routines are tailored to the environment of the CALTECH/ JPL-LSCL which included a special operating system to interface with the testbed. Input commands for a particular experiment (wideband, narrowband, or sine-dwell) were computed on-line and then issued to respective actuators by the operating system. The operating system also took measurements through displacement sensors and passed them back to the software for storage and off-line processing. In order to make use of AU-FREDI's I/O data transfer routines, a user would need to provide an operating system capable of overseeing such functions between the software and the experimental setup at hand. The program documentation contains information designed to support users in either providing such an operating system or modifying the system identification algorithms for use with input/output data files. It provides a history of the theoretical, algorithmic and software development efforts including operating system requirements and listings of some of the various special purpose subroutines which were developed and optimized for Lahey FORTRAN compilers on IBM PC-AT computers before th

$J/?$ production in Au+Au collisions at RHIC and the nuclear absorption  

E-print Network

It is shown that a QCD based nuclear absorption model, with few parameters fixed to reproduce experimental $J/\\psi$ yield in 200 GeV pp/pA and 450 GeV pA collisions can explain the preliminary PHENIX data on the centrality dependence of $J/\\psi$ suppression in Cu+Cu collisions at RHIC energy, $\\sqrt{s_{NN}}$=200 GeV. However, the model does not give satisfactory description to the preliminary PHENIX data on the centrality dependence of $J/\\psi$ suppression in Au+Au collisions. The analysis suggest that in Au+Au collisions, $J/\\psi$ are suppressed in a medium unlike the medium produced in SPS energy nuclear collisions or in RHIC energy Cu+Cu collisions.

MeV ion beam mixing of Au/Si and Au/Ge systems  

NASA Astrophysics Data System (ADS)

An experimental apparatus for X- Y electrostatic scanning implantation of MeV ions and in situ Rutherford backscattering analysis has been set up on a 3 MV tandem accelerator at Fudan University. MeV ion beam mixing in Au/Si and Au/Ge systems has been studied. The uniformity of the scanning beam was checked by the implanted Au + ion distribution in a Si wafer. Au thin films with thickness of about 32 nm were evaporated on Si and Ge single-crystal substrates, and the samples were then bombarded by 1 MeV Ag + ions with various fluences at room temperature and analyzed in situ using the 2 MeV He + ion RBS technique.

Surface effects on the radiation response of nanoporous Au foams  

SciTech Connect

We report on an experimental and simulation campaign aimed at exploring the radiation response of nanoporous Au (np-Au) foams. We find different defect accumulation behavior by varying radiation dose-rate in ion-irradiated np-Au foams. Stacking fault tetrahedra are formed when np-Au foams are irradiated at high dose-rate, but they do not seem to be formed in np-Au at low dose-rate irradiation. A model is proposed to explain the dose-rate dependent defect accumulation based on these results.

Surface crystalline gold silicide formation on the Au(100) surface  

NASA Astrophysics Data System (ADS)

Crystalline gold silicide formation on the Au(100) surface was studied using a scanning tunneling microscope. By introducing low coverage of Si on the Au surface at room temperature, the Au (5 × 20) reconstruction was partially transformed to disordered structure with islands. Island formation was discussed as the result of Si diffusion on the Au surface. Upon annealing below the eutectic temperature, the Au surface generally transformed to a metastable gold silicide structure. Structure of the observed surface was compared to former experimental results, showing good agreement.

Enhanced spin pumping at yttrium iron garnet/Au interfaces  

SciTech Connect

Spin injection across the ferrimagnetic insulator yttrium iron garnet (YIG)/normal metal Au interface was studied using ferromagnetic resonance. The spin mixing conductance was determined by comparing the Gilbert damping parameter {alpha} in YIG/Au and YIG/Au/Fe heterostructures. The main purpose of this study was to correlate the spin pumping efficiency with chemical modifications of the YIG film surface using in situ etching and deposition techniques. By means of Ar{sup +} ion beam etching, one is able to increase the spin mixing conductance at the YIG/Au interface by a factor of 5 compared to the untreated YIG/Au interface.

Strangelet search in Au+Au collisions at sNN=200 GeV  

Microsoft Academic Search

We have searched for strangelets in a triggered sample of 61 million central (top 4%) Au+Au collisions at sNN=200 GeV near beam rapidities at the STAR solenoidal tracker detector at the BNL Relativistic Heavy Ion Collider. We have sensitivity to metastable strangelets with lifetimes of order =>0.1 ns, in contrast to limits over ten times longer in BNL Alternating Gradient

Baryon spectra in Au + Au collisions: Preliminary results from E-866  

SciTech Connect

Measurements are presented of single particle spectra from Au targets using the recently commissioned Au-beam at 11.6 GeV/c per nucleon from the BNL Tandem-Booster-AGS accelerator facilities. Protons and deuterons were detected with the measuring the 25msr E-802 spectrometer. Collision centrality was determined by measuring the forward energy in a calorimeter subtending a 1.2[degrees] cone about 0[degrees]. Some comparisons with the cascade code ARC have been made.

We present ?? correlation measurements in heavy-ion collisions for Au+Au collisions at sqrt[s_{NN}]=200??GeV using the STAR experiment at the Relativistic Heavy-Ion Collider. The Lednický-Lyuboshitz analytical model has been used to fit the data to obtain a source size, a scattering length and an effective range. Implications of the measurement of the ?? correlation function and interaction parameters for dihyperon searches are discussed. PMID:25635541

Critical Behavior in Peripheral Au + Au Collisions at 35 MeV/u  

E-print Network

The signals theoretically predicted for the occurrence of a critical behavior (conditional moments of charge distributions, Campi scatter plot, fluctuations of the size of the largest fragment, power law in the charge distribution, intermittency) have been found for peripheral events in the reaction Au+Au at 35 MeV/u. The same signals have been studied with a dynamical model which foresees phase transition, like the Classical Molecular Dynamics.

Di-Hadron Correlations with Identified Leading Hadrons in 200 GeV Au+Au and d+Au Collisions at STAR  

E-print Network

The STAR collaboration presents new two-dimensional di-hadron correlations with leading hadrons in 200 GeV central Au+Au and minimum bias d+Au collisions to explore hadronization mechanisms in the quark gluon plasma. The enhancement of the jet-like yield for leading pions in Au+Au data with respect to the d+Au reference and the absence of enhancement for leading non-pions (protons and kaons) are discussed within the context of quark recombination. The correlated yield at large angles, specifically in the \\emph{ridge region}, is significantly higher for leading non-pions than pions. The consistencies of the constituent quark scaling, azimuthal harmonic model and a mini-jet modification model description of the data are tested, providing further constraints on hadronization.

Bactericidal mechanisms of Au@TNBs under visible light irradiation.  

PubMed

Au@TNBs nanocomposites were synthesized by depositing Au nanoparticles onto the surfaces of TiO2 nanobelts (TNBs). The disinfection activities of Au@TNBs on model cell type, Gram-negative Escherichia coli (E. coli), were examined under visible light irradiation conditions. Au@TNBs exhibited stronger bactericidal properties toward E. coli than those of TNBs and Au NPs under visible light irradiation. The bactericidal mechanisms of Au@TNBs under light conditions were explored, specifically, the specific active species controlling the inactivation of bacteria were determined. Active species (H2O2, diffusing OH, O2(-), (1)O2, and e(-)) generated by Au@TNBs were found to play important roles on the inactivation of bacteria. Moreover, the concentrations of H2O2, OH, O2(-), and (1)O2 generated in the antimicrobial system were estimated. Without the presence of active species, the direct contact of Au@TNBs with bacterial cells was found to have no bactericidal effect. The reusability of Au@TNBs were also determined. Au@TNBs exhibited strong antibacterial activity toward E. coli even in five consecutively reused cycles. This study indicated that the fabricated Au@TNBs could be potentially utilized to inactivate bacteria in water. PMID:25656356

Surface-assisted cyclotrimerization of arylalkynes was studied on Au(111) by means of scanning tunneling microscopy (STM) under ultra-high vacuum (UHV) conditions. Upon thermal activation, cyclotrimerization of 1,3,5-tris-(4-ethynylphenyl)benzene proceeds readily and with high selectivity, and results in two-dimensional covalently bonded polyphenylene nanostructures exhibiting a honeycomb topology.

Ag-modified Au nanocavity SERS substrates.  

PubMed

The engineering of cavity void metallic arrays allows to vary the plasmon-polariton mode energies from the near infrared to the ultraviolet through the tuning of the void height and diameter, and the selection of the appropriate material. Typically Au nanocavity substrates can be grown with better reproducibility, homogeneity, and stability, while Ag structures display significantly larger SERS enhancements. To exploit these two apparently excluding aspects, quality and enhancement, we report a detailed study of 500 nm Au-nanocavity templates modified by the controlled electrochemical deposition of 100 Ag layers, a thickness similar to the visible light skin-depth of bulk Ag. The SERS amplification of the ordered cavity-arrays is determined using 4-mercaptopyridine as a non-electronic resonant molecular probe. The ultrathin Ag layer modification of the Au substrates results in a strong amplification of the SERS signal both in the red and the green part of the spectrum, and in a spectral shift of the Raman resonance scans. These observations are assigned to Ag-induced changes in the plasmon-polariton response of the nanostructure. The reported results provide a general platform for the preparation of renewable SERS-active substrates that combine the durability and higher quality of Au nanotemplates, with the enhanced SERS amplification factors of Ag.

Nano Au-decorated boron nitride nanotubes: Conductance modification and field-emission enhancement  

Microsoft Academic Search

This letter reports the electrical and field-emission properties of Au-decorated boron nitride nanotubes (Au-BNNTs). The insulating BNNTs become metallic after Au coating as the Au coverage exceeds a critical value. The Au decoration modifies the work function of the BNNTs and, as a consequence, the field-emission current densities of Au-BNNTs are significantly enhanced. Correspondingly, the turn-on field of the Au-BNNTs

Nuclear modification factors of ? mesons in d+Au, Cu+Cu, and Au+Au collisions at sNN=200GeV  

NASA Astrophysics Data System (ADS)

The PHENIX experiment at the Relativistic Heavy Ion Collider has performed systematic measurements of ? meson production in the K+K- decay channel at midrapidity in p+p, d+Au, Cu+Cu, and Au+Au collisions at sNN=200GeV. Results are presented on the ? invariant yield and the nuclear modification factor RAA for Au+Au and Cu+Cu, and RdA for d+Au collisions, studied as a function of transverse momentum (1Au+Au collisions, the RAA of ? exhibits a suppression relative to expectations from binary scaled p+p results. The amount of suppression is smaller than that of the ?0 and the ? in the intermediate pT range (2-5GeV/c), whereas, at higher pT, the ?, ?0, and ? show similar suppression. The baryon (proton and antiproton) excess observed in central Au+Au collisions at intermediate pT is not observed for the ? meson despite the similar masses of the proton and the ?. This suggests that the excess is linked to the number of valence quarks in the hadron rather than its mass. The difference gradually disappears with decreasing centrality, and, for peripheral collisions, the RAA values for both particle species are consistent with binary scaling. Cu+Cu collisions show the same yield and suppression as Au+Au collisions for the same number of Npart. The RdA of ? shows no evidence for cold nuclear effects within uncertainties.

Study of Cronin effect and nuclear modification of strange particles in d Au and Au Au collisions at 200 GeV in PHENIX  

NASA Astrophysics Data System (ADS)

Effects of strangeness on nuclear modification in d Au and Au Au collisions at 200 GeV are studied, in order to quantify the effects of quark content and mass. Measurements of ratios of the yields in central collisions to the yields in peripheral collisions are performed for Lgr baryon and phgr meson. Found results show little dependence of particle suppression or enhancement on mass and strange content, but rather prominent difference in nuclear modification between mesons and baryons.

Synthesis, structure, and bonding in K12Au21Sn4. A polar intermetallic compound with dense Au20 and open AuSn4 layers  

SciTech Connect

The new phase K{sub 12}Au{sub 21}Sn{sub 4} has been synthesized by direct reaction of the elements at elevated temperatures. Single crystal X-ray diffraction established its orthorhombic structure, space group Pmmn (No. 59), a = 12.162(2); b = 18.058(4); c = 8.657(2) {angstrom}, V = 1901.3(7) {angstrom}{sup 3}, and Z = 2. The structure consists of infinite puckered sheets of vertex-sharing gold tetrahedra (Au{sub 20}) that are tied together by thin layers of alternating four-bonded-Sn and -Au atoms (AuSn{sub 4}). Remarkably, the dense but electron-poorer blocks of Au tetrahedra coexist with more open and saturated Au-Sn layers, which are fragments of a zinc blende type structure that maximize tetrahedral heteroatomic bonding outside of the network of gold tetrahedra. LMTO band structure calculations reveal metallic properties and a pseudogap at 256 valence electrons per formula unit, only three electrons fewer than in the title compound and at a point at which strong Au-Sn bonding is optimized. Additionally, the tight coordination of the Au framework atoms by K plays an important bonding role: each Au tetrahedra has 10 K neighbors and each K atom has 8-12 Au contacts. The appreciably different role of the p element Sn in this structure from that in the triel members in K{sub 3}Au{sub 5}In and Rb{sub 2}Au{sub 3}Tl appears to arise from its higher electron count which leads to better p-bonding (valence electron concentrations = 1.32 versus 1.22).

Nuclear modification factors of phi mesons in d+Au, Cu+Cu and Au+Au collisions at sqrt(S_NN)=200 GeV  

E-print Network

The PHENIX experiment at the Relativistic Heavy Ion Collider (RHIC) has performed systematic measurements of phi meson production in the K+K- decay channel at midrapidity in p+p, d+Au, Cu+Cu and Au+Au collisions at sqrt(S_NN)=200 GeV. Results are presented on the phi invariant yield and the nuclear modification factor R_AA for Au+Au and Cu+Cu, and R_dA for d+Au collisions, studied as a function of transverse momentum (1Au+Au collisions, the R_AA of phi exhibits a suppression relative to expectations from binary scaled p+p results. The amount of suppression is smaller than that of the neutral pion and the eta meson in the intermediate p_T range (2--5 GeV/c); whereas at higher p_T the phi, pi^0, and eta show similar suppression. The baryon (protons and anti-protons) excess observed in central Au+Au collisions at intermediate p_T is not observed for the phi meson despite the similar mass of the proton and the phi. This suggests that the excess is linked to the number of constituent quarks rather than the hadron mass. The difference gradually disappears with decreasing centrality and for peripheral collisions the R_AA values for both particles are consistent with binary scaling. Cu+Cu collisions show the same yield and suppression as Au+Au collisions for the same number of N_part. The R_dA of phi shows no evidence for cold nuclear effects within uncertainties.

Structure-activity relationships in cytotoxic Au(I)/Au(III) complexes derived from 2-(2'-pyridyl)benzimidazole.  

PubMed

Gold(I) and gold(III) complexes derived from 2-(2'-pyridyl)benzimidazole (pbiH) were proven to be a promising class of in vitro antitumor agents against A2780 human ovarian cancer cells. In this paper, a comparative electrochemical, UV-vis absorption, and emission spectroscopic investigation is reported on pbiH, the two mononuclear Au(III) complexes [(pbi)AuX2] (X = Cl (1), AcO (2)), the four mononuclear Au(I) derivatives [(pbiH)AuCl] (3), [(pbiH)Au(PPh3)]PF6 ((4(+))(PF6(-))), [(pbi)Au(PPh3)] (5), and [(pbi)Au(TPA)] (6), the three mixed-valence Au(III)/Au(I) complexes [(?-pbi)Au2Cl3] (7), [(Ph3P)Au(?-pbi)AuX2]PF6 (X = Cl ((8(+))(PF6(-))), AcO ((9(+))(PF6(-)))), and the binuclear Au(I)-Au(I) compound [(?-pbi)Au2(PPh3)2]PF6 ((10(+))(PF6(-))). All complexes feature irreversible reduction processes related to the Au(III)/Au(I) or Au(I)/Au(0) processes and peculiar luminescent emission at about 360-370 nm in CH2Cl2, with quantum yields that are remarkably lower ((0.7-14.5) × 10(-2)) in comparison to that determined for the free pbiH ligand (31.5 × 10(-2)) in the same solvent. The spectroscopic and electrochemical properties of all complexes were interpreted on the grounds of time-dependent PBE0/DFT calculations carried out both in the gas phase and in CH2Cl2 implicitly considered within the IEF-PCM SCRF approach. The electronic structure of the complexes, and in particular the energy and composition of the Kohn-Sham LUMOs, can be related to the antiproliferative properties against the A2780 ovarian carcinoma cell line, providing sound quantitative structure-activity relationships and shedding a light on the role played by the global charge and nature of ancillary ligands in the effectiveness of Au-based antitumor drugs.

Observation of strongly deformed ground-state configurations in184Au and183Au by laser spectroscopy  

NASA Astrophysics Data System (ADS)

Resonance ionization mass spectroscopy (RIMS) and pulsed-laser induced desorption (PLID) have been combined in order to study the isotope shift (IS) and hyperfine structure (HFS) of184Au (T1/2=53 s) and183Au (T1/2=42 s) in the 6s2S1/2 ? 6p2P1/2 (?=267 nm) transition. The Au isotopes were obtained as daughters in the decay of184,183Hg produced and mass separated at the new ISOLDE-3 facility at CERN. It was found that the strong deformation ? 2}-0.25 setting in at186Au persists down to183Au.

Photosynthetic electron transport system promotes synthesis of Au-nanoparticles.  

PubMed

In this communication, a novel, green, efficient and economically viable light mediated protocol for generation of Au-nanoparticles using most vital organelle, chloroplasts, of the plant system is portrayed. Thylakoids/chloroplasts isolated from Potamogeton nodosus (an aquatic plant) and Spinacia oleracea (a terrestrial plant) turned Au³? solutions purple in presence of light of 600 µmol m?² s?¹ photon flux density (PFD) and the purple coloration intensified with time. UV-Vis spectra of these purple colored solutions showed absorption peak at ?545 nm which is known to arise due to surface plasmon oscillations specific to Au-nanoparticles. However, thylakoids/chloroplasts did not alter color of Au³? solutions in dark. These results clearly demonstrated that photosynthetic electron transport can reduce Au³? to Au? which nucleate to form Au-nanoparticles in presence of light. Transmission electron microscopic studies revealed that Au-nanoparticles generated by light driven photosynthetic electron transport system of thylakoids/chloroplasts were in range of 5-20 nm. Selected area electron diffraction and powder X-ray diffraction indicated crystalline nature of these nanoparticles. Energy dispersive X-ray confirmed that these nanoparticles were composed of Au. To confirm the potential of light driven photosynthetic electron transport in generation of Au-nanoparticles, thylakoids/chloroplasts were tested for their efficacy to generate Au-nanoparticles in presence of light of PFD ranging from 60 to 600 µmol m?² s?¹. The capacity of thylakoids/chloroplasts to generate Au-nanoparticles increased remarkably with increase in PFD, which further clearly demonstrated potential of light driven photosynthetic electron transport in reduction of Au³? to Au? to form nanoparticles. The light driven donation of electrons to metal ions by thylakoids/chloroplasts can be exploited for large scale production of nanoparticles. PMID:23976990

Fabrication of monometallic (Co, Pd, Pt, Au) and bimetallic (Pt/Au, Au/Pt) thin films with hierarchical architectures as electrocatalysts  

NASA Astrophysics Data System (ADS)

Co thin films with novel hierarchical structures were controllably fabricated by simple electrochemical deposition in the absence of hard and soft templates, which were used as sacrificial templates to further prepare noble metal (Pd, Pt, Au) hierarchical micro/nanostructures via metal exchange reactions. SEM characterization demonstrated that the resulting noble metal thin films displayed hierarchical architectures. The as-prepared noble metal thin films could be directly used as the anode catalysts for the electro-oxidation of formic acid. Moreover, bimetallic catalysts (Pt/Au, Au/Pt) fabricated based on the monometallic Au, Pt micro/nanostructures exhibited the higher catalytic activity compared to the previous monometallic catalysts.

Non-local first-principles calculations in Cu-Au, Ag-Au and Cu-Ag  

NASA Astrophysics Data System (ADS)

Cu-Au is the prototypical alloy system used to exemplify ordering and compound formation, and serves as a testbed for all new alloy theory methods. Yet, despite the importance of this system, conventional density functional theory (DFT) calculations with semi-local approximations (GGA) have two dramatic failures in describing the energies of this system: 1) DFT predicts incorrect ordered ground states for Au-rich compositions, and 2) DFT formation energies of the observed Cu3Au and CuAu compounds are nearly a factor of two smaller in magnitude than experimental values. Here, we show how modern extensions of DFT based on non-local interactions can rectify both of these failures. Using the self-consistent non-local HSE06 functional, the formation energies of Cu3Au and CuAu are -71 and -91 meV/atom, respectively, which are in excellent agreement with the experimental measurements. The semi-local GGA predicted CuAu2 is not a stable phase in the HSE06 calculations, and CuAu3 with the L12 structure is theoretically predicted as a stable phase. For Ag-Au, both semi-local GGA and non-local HSE06 functionals give similar formation energies. The electronic structures are used to explain these different phenomena in Cu-Au and Ag-Au.

Enhanced frequency upconversion of Sm 3+ ions by elliptical Au nanoparticles in dichroic Sm 3+: Au-antimony glass nanocomposites  

NASA Astrophysics Data System (ADS)

Dichroic Sm 3+: Au-antimony glass nanocomposites are synthesized in a new reducing glass (dielectric) matrix (mol%) K 2O-B 2O 3-Sb 2O 3 (KBS) by a single-step melt-quench technique involving selective thermochemical reduction. X-ray diffraction (XRD) and selected area electron diffraction (SAED) results indicate that Au 0 nanoparticles are grown along the (2 0 0) plane direction. The transmission electron microscopic (TEM) image reveals the elliptical Au 0 nanoparticles having major axis range 12-17 nm. Dichroic behavior is due to elliptical shape of Au 0 nanoparticles of aspect ratio ˜1.2. Au 0 NPs of concentration of 0.03 wt% (4.1 × 10 18 atoms/cm 3) drastically enhances the intensity (˜7-folds) of electric dipole 4G 5/2 ? 6H 9/2 red transition (636 nm) of Sm 3+ ions and then attenuates with further increase in Au 0 concentration. The magnetic dipole 4G 5/2 ? 6H 5/2 green (566 nm) and 4G 5/2 ? 6H 7/2 orange (602 nm) transitions remain almost unaffected by presence of nano Au 0. Local field enhancement (LFE) induced by Au 0 SPR and energy transfer (ET) from fluorescent Au 0 ? Sm 3+ ions are found to be responsible for the enhancement while reverse ET from Sm 3+ ? Au 0 and optical re-absorption due to Au 0 SPR for attenuation.

Facile oxidation of NHC-Au(I) to NHC-Au(III) complexes by CsBr3.  

PubMed

CsBr3 was investigated as a new and convenient oxidant for NHC-Au(I) complexes (NHC = imidazo[1,5-a]pyridin-3-ylidene) for the preparation of the respective Au(III) complexes. The Au(I) complexes were synthesized by the silver salt method using [(NHC)2Ag]PF6 and (tht)AuBr. Unexpectedly, the reactions yielded both neutral (NHC)AuBr and ionic [(NHC)2Au]PF6, depending on the N-substituent of the NHC ligand. Oxidation with CsBr3 gave the complexes (NHC)AuBr3 and [(NHC)2AuBr2]PF6 in high yields and purity, which proves the suitability of this reagent. The complexes were further characterised by X-ray diffraction and electronic absorption and emission spectroscopy. The Au(I) complexes exhibit a dual emission attributable to intraligand fluorescence and phosphorescence at both room temperature and 77 K. Upon irradiation with polychromatic light (? > 305 nm), the Au(III) complexes are cleanly photo-reduced to the Au(I) congener. PMID:24777298

Possible triplet superconductivity in Nb/Au/CoFe trilayers  

NASA Astrophysics Data System (ADS)

We have fabricated the Nb/Au and Nb/CoFe bilayer and Nb/Au/CoFe trilayer samples and investigated their T_c's by systematically varying d_Nb, d_CoFe, and d_Au. These samples were deposited on the oxidized Si substrates using DC magnetron sputtering system and the superconducting critical temperature Tc of the samples were measured electrically using standard DC and AC 4-point method. The SN bilayer system showed well-known exponential-like dependence of Tc on d_Au, while the SF bilayer system displayed oscillatory dependence of Tc on d_CoFe, as expected from the SF proximity effect theory. On the other hand, with fixed d_Nb and d_CoFe, the Tc of SNF trilayers as a function of d_Au increased rapidly for d_Au < 10 nm and then approached a saturated value near d_Au = 200 nm. The T_c's of these trilayer systems are higher than a theory based on conventional singlet superconductivity can predict. Moreover, we observed small oscillatory Tc behavior in the trilayer system when d_Au is varied in the range of 30 nm < d_Au < 90 nm. In order to explain our unexpected data, we propose the possibility of triplet superconductivity created inside Au layer.

Enrichment of the Superheavy Element Roentgenium (Rg) in Natural Au  

NASA Astrophysics Data System (ADS)

Based on the observation of the long-lived isotopes of roentgenium, 261Rg and 265Rg (Z = 111, t1/2?108 y) in natural Au, an experiment was performed to enrich Rg in 99.999% Au. 16 mg of Au were heated in vacuum for two weeks at a temperature of 1127°C (63°C above the melting point of Au). The content of 197Au and 261Rg in the residue was studied with high resolution inductively coupled plasma-sector field mass spectrometry (ICP-SFMS). The residue of Au was 3×10-6 of its original quantity. The recovery of Rg was a few percent. The abundance of Rg compared to Au in the enriched solution was about 2×10-6, which is a three to four orders of magnitude enrichment. It is concluded that the evaporation rate of Rg from an Au matrix in vacuum at 63°C above the Au melting point is lower than that of Au. This experiment reinforces our first observation of Rg in a terrestrial material. As before it is concluded that a long-lived isomeric state exists in 261Rg and that it probably belongs to a new class of isomeric states, namely high spin (K-type) super- or hyperdeformed isomeric states.

We report a high-resolution photoemission study of Au evaporated on rf-sputtered a-Si:H at room temperature. Three regions of coverage can be classified according to the behavior of the valence-band and core-level spectra: an unreacted region with an equivalent thickness of 2 Å, followed by an intermixed Au/a-Si overlayer (~9 Å), and a dual-phase region at higher coverage. Au adatoms are dispersed in the unreacted region. They subsequently cluster in the intermixed region, where they attach to Si atoms that are not hydrogen bonded, suggesting that the intermixed Si is mainly from those that have dangling bonds. In the dual-phase region, two sets of Au 4f core levels evolve with higher binding energy, one from Au intermixed with Si, and the lower one exhibiting pure gold character. The interface eventually ends up with the sequence: a-Si:H(sub.)+(pure Au mixed with intermixed Au/Si)+(vac). This is unlike the case of Au on c-Si, which has a pure gold layer sandwiched by intermixed Au/Si complexes along the surface normal. Traces of silicon atoms on top of composite surfaces appear even at the highest coverage, 205 Å, of the gold deposit. The applicability of the four models previously used for the Au/c-Si interface is also briefly discussed.

Probing the quenching of CdSe/ZnS qdots by Au, Au/Ag, and Au/Pd nanoparticles.  

PubMed

The resonance energy transfer between CdSe/ZnS quantum dots (qdots) and three metallic nanoparticles (NPs) with different surface plasmon resonance (SPR) characteristics were studied. Gold, gold/silver and gold/palladium NPs were used as energy acceptors for qdots with donor emission at 570 nm. Due to the different spectral overlaps between the SPR signatures and qdot emission, varied energy transfer characteristics were observed. The energy transfer was quantified via the Stern-Volmer relationship, since in this study the energy transfer was collision based. The Au/Ag and Au/Pd NPs in particular showed high K(SV) values, while the Au NPs showed much lower energy transfer efficiency. Since the NPs used in this study were relatively large (d ~ 15-20 nm), the experimental system was also influenced by the NP extinction coefficients of ?10(8) M(-1) cm(-1). To address this potential inner filter effect, the quenching profiles were normalized by SPR transmittance. The results are important to the field, as many of these classes of nanomaterials are being employed in energy transfer based studies, as well as in colorimetric sensing. PMID:23060607

Acid/Base-Controlled Au(I)/Au(0) Reductive Transformations of the Monogold [(?14-Au)Pd22(CO)20(PEt3)8](+) Monocation into Three Different Neutral Digold Nanoclusters: Au2Pd21(CO)20(PEt3)10, Au2Pd28(CO)26(PEt3)10, and New Five-Layer Hexagonal Close-Packed (?12-Au)2Pd42(CO)30(PEt3)12 with a Trigonal-Bipyramidal AuPd3Au Kernel.  

PubMed

The monogold [(?14-Au)Pd22(CO)20(PEt3)8](+) nanocation (2, with a [(CF3CO2)2H](-) counterion) is shown to be a versatile precursor for the generation of three different neutral Au-Pd nanoclusters with double gold content in their distinctly dissimilar bimetallic architectures. These carbon monoxide (CO)-induced conversions are based on the reduction of Au(I) to Au(0) that is controlled by the reaction medium. Under basic and acidic conditions, the known Au2Pd21(CO)20(PEt3)10 (3; >90% yield) and Au2Pd28(CO)26(PEt3)10 (4; ?40% yield), respectively, were obtained, whereas neutral conditions gave rise to the new (?12-Au)2Pd42(CO)30(PEt3)12 (1; ?10-20% yield; all yields based on gold). The molecular structure of 1, established from a 100 K CCD X-ray diffraction study, consists of a five-layer hexoganol close-packed (hcp) Au2Pd42 framework of pseudo-D3h symmetry (crystallographic D3 site symmetry) of the Pd6/AuPd9/Pd12/AuPd9/Pd6 layer sequence, with the Au atoms centering two identical hcp (?12-Au)Pd12 face-fused anti-cuboctahedral fragments. The 12 Et3-attached P atoms are coordinated to the triangular vertex Pd atoms in the four outer layers (except the middle Pd12); all five layers are stapled by interlayer bridging COs. The radial Aucent-Pd mean distance of 2.79 Å within the two symmetry-equivalent (?12-Au)Pd12 anti-cuboctahedral fragments of 1 is identical with the radial Pdcent-Pd mean distances within hcp (?12-Pd)Pd12 anti-cuboctahedral fragments of the two geometrically related nondistorted layered structures of Pd52(CO)36(PEt3)14 and [Ni9Pd33(CO)41(PPh3)6](4-) ([PPh4](+) counterion), indicating a strain-free structural effect upon the substitution of Au for Pd in their analogous hcp layer-stacked arrangements. It provides prime evidence for an extension to 1 of our previous self-consistent experimental/theoretical-based hypothesis for delocalization of the 6s valence Au electrons in Au2Pd21 (3) and Au2Pd28 (4) toward a formal closed-shell Au(+) configuration that is electronically equivalent to that of zerovalent Pd.

``Hot spots'' induced near-field enhancements in Au nanoshell and Au nanoshell dimer  

NASA Astrophysics Data System (ADS)

The influence of “hot spots” on the near-field properties of Au nanoshell and Au nanoshell dimers have been investigated by means of the finite element method. It is found with increasing the pinhole radius R that the maximal enhancement of near-field for Au nanoshell with pinhole parallel to the polarization increases from 17.906 at R=0 nm to 36.979 at R=0.8 nm, and then almost shows a negligible radius dependence. Large electric fields also can be observed inside the pinhole perpendicular to the polarization, which increases with increasing the pinhole radius. The near-field of Au nanoshell dimer depends strongly on the polarization and propagation directions of the incident light. Exponential decay behavior is found for the maximal enhancement of the electric field in the dimer junction as a function of the dimer separation. Furthermore, a very strong electric field is found in the junction between two Au nanoshells when the pinholes are located near the gap between the nanoshells.

Suppression of high transverse momentum ?0 spectra in Au + Au collisions at RHIC  

NASA Astrophysics Data System (ADS)

Au + Au, s1/2 = 200 GeV measurements at RHIC, obtained with the PHENIX, STAR, PHOBOS and BRAHMS detectors, have all indicated a suppression of high p? particle production, relative to an appropriately normalized NN level. For central collisions and vanishing pseudo-rapidity these experiments exhibit suppression in charged meson production, especially at medium-to-large transverse momenta. In the PHENIX experiment similar behaviour has been reported for ?0 spectra. In a recent work [1] on the simpler D + Au interaction, to be considered perhaps as a tune-up for Au + Au, we reported on a pre-hadronic cascade mechanism which can explain the mixed observation of moderately reduced p? suppression at higher pseudo-rapidity as well as the Cronin enhancement at mid-rapidity. Here, we present the extension of this work to the more massive ion-ion collisions. Our major thesis is that much of the suppression is generated in a late stage cascade of colourless pre-hadrons produced after an initial short-lived coloured phase. We present a pQCD argument to justify this approach and to estimate the time duration ?p of this initial phase. Of essential importance is the brevity in time of the coloured phase existence relative to that of the strongly interacting pre-hadron phase, the latter essentially an interactive cascade. These distinctions in phase are of course not strict, but adequate for treating the suppression of moderate and high p? mesons.

Facile preparation of SERS-active nanostructured Au spheres by simple reduction of AuCl4- ions with EDOT.  

PubMed

Uniform submicron-scale Au spheres with an average dimension of 574 nm were facilely prepared from the redox reaction between HAuCl4 and 3,4-ethylenedioxythiophene (EDOT) in aqueous solution under ambient conditions. HAuCl4 precursor readily polymerized to poly(3,4-ethylenedioxythiophene) (PEDOT) and metallic Au spheres simultaneously formed within a short period of time. The Au spheres are consisted of two slightly different types of spherical particles based on their surface textures. Major raspberry-like Au spheres are formed through the assembly of very tiny Au nanoparticles, while minor rosette-like Au spheres are formed through the dense packing of Au nanoplates. Both Au spheres are pure metallic face-centered cubic Au based on X-ray photoelectron spectroscopy and powder X-ray diffraction. The resultant Au spheres are adequate for application to surface-enhanced Raman scattering (SERS) due to their rough surfaces and nanogaps on the surfaces. Both methylene blue and crystal violet molecules were detectable at concentrations as low as 10(-7) M. PMID:24461856

Electrostatic assembles and optical properties of Au CdTe QDs and Ag/Au CdTe QDs  

NASA Astrophysics Data System (ADS)

Au-CdTe and Ag/Au-CdTe assembles were firstly investigated through the static interaction between positively charged cysteamine-stabilized CdTe quantum dots (QDs) and negatively charged Au or core/shell Ag/Au nano-particles (NCs). The CdTe QDs synthesized in aqueous solution were capped with cysteamine which endowed them positive charges on the surface. Both Au and Ag/Au NCs were prepared through reducing precursors with gallic acid obtained from the hydrolysis of natural plant poly-phenols and favored negative charges on the surface of NCs. The fluorescence spectra of CdTe QDs exhibited strong quenching with the increase of added Au or Ag/Au NCs. Railey resonance scattering spectra of Au or Ag/Au NCs increased firstly and decreased latter with the concentration of CdTe QDs, accompanied with the solution color changing from red to purple and colorless at last. Experimental results on the effects of gallic acid, chloroauric acid tetrahydrate and other reagents demonstrated the static interaction occurred between QDs and NCs. This finding reveals the possibilities to design and control optical process and electromagnetic coupling in hybrid structures.

Pulsation and orbit of AU Pegasi  

NASA Astrophysics Data System (ADS)

AU Pegasi is a pulsating star in a spectroscopic binary system with an orbital period of 53.26 days. Between 1960 and 1990 an extremely rapid period increase was observed in the value of the pulsation period, but in the last 15 years the observation show that the period set in 2.411 days. Fourier analysis of photometric data obtained during the ASAS project and those taken at the Piszkésteto Mountain Station of the Konkoly Observatory during 1994-2005 indicate that AU Pegasi is pulsating in two modes simultaneously, and the ratio of the frequencies of the two modes is 0.706, a value common for double-mode classical Cepheids. A careful analysis of other photometric observations obtained during the era of the strong period increase also revealed existence of a second mode. This may suggest that this star is not a Type II Cepheid, despite its galactic position.

-Au core-cap nanostructure arrays  

NASA Astrophysics Data System (ADS)

SiO2-Au core-cap nanostructure arrays were prepared by dip-coating technique combined with wet chemical reduction method. The surface morphologies, structures, and optical properties of the obtained samples were characterized by scanning electron microscopy, X-ray diffraction, and ultraviolet-visible spectrophotometer, respectively. The surface-enhanced Raman scattering (SERS) activity of SiO2-Au core-cap nanostructure arrays substrates was investigated using leucine as probe molecule. And the relationship between the SERS effect and the surface plasmon resonance (SPR) peaks was discussed. High-quality, stable, and reproducible SERS spectra of leucine were successfully obtained. When the maximum SPR peak matched with the excitation wavelength, the substrate gave rise to the highest SERS enhancement. Furthermore, six different fluorescent dyes were also chosen as probe molecules. It was found that the substrate showed good Raman enhancement and highly efficient fluorescence quenching characteristic on these fluorescent dyes.
