    To evaluate stromal demarcation lines following corneal cross-linking (CXL) using anterior segment optical coherence tomography in patients with keratoconus and nonkeratoconic asymmetric topography. Fifth-nine eyes of 59 patients were enrolled in a retrospective comparative case series, of which 19 eyes had keratoconus and 40 eyes had asymmetric topography. Eyes with asymmetric topography were treated in preparation for photorefractive keratectomy. One month after CXL, a stromal demarcation line was evaluated at 5 standardized corneal points using anterior segment optical coherence tomography. Mean stromal demarcation line depths were measured at 5 points on the cornea, namely, centrally, 3.0 mm temporally, 1.5 mm temporally, 3.0 mm nasally, and 1.5 mm nasally. For the keratoconus group, the values were 178 ± 47, 123 ± 15, 152 ± 47, 125 ± 23, and 160 ± 43 μm, respectively. For the asymmetric corneal topography group (without keratoconus), they were 305 ± 64, 235 ± 57, 294 ± 50, 214 ± 54, and 285 ± 58 μm, respectively. There was no correlation between central corneal pachymetry and stromal demarcation line depth in all 5 measured corneal points in both groups. CXL treatment profiles are similar in keratoconic and nonkeratoconic eyes with asymmetric topography.

    Full Text Available A study of genetic variation among 10 pairs of chromosomes extracted from 13 tropical sweet corn inbred lines, using 99 microsatellite markers, revealed a wide range of genetic diversity. Allelic richness and the number of effective alleles per chromosome ranged from 2.78 to 4.33 and 1.96 to 3.47, respectively, with respective mean values of 3.62 and 2.73. According to the Shannon's information index (I and Nei's gene diversity coefficient (Nei, Chromosome 10 was the most informative chromosome (I = 1.311 and Nei = 0.703, while Chromosome 2 possessed the least (I = 0.762 and Nei = 0.456. Based on linkage disequilibrium (LD measurements for loci less than 50 cM apart on the same chromosome, all loci on Chromosomes 1, 6 and 7 were in equilibrium. Even so, there was a high proportion of genetic variation in Chromosomes 4, 5, 8, 9 and 10, thereby revealing their appropriateness for use in the genetic diversity investigations among tropical sweet corn lines. Chromosome 4, with the highest number of loci in linkage disequilibrium, was considered the best for marker-phenotype association and QTL mapping, followed by Chromosomes 5, 8, 9 and 10.

    Full Text Available Effective conservation of coastal marine mammals is largely dependent on reliable knowledge of their abundance, as well as the ecological and human factors driving their distribution. In developing countries, lack of resources and capacity frequently impedes research needed to estimate abundance and to determine the ecological requirements of coastal marine mammals and the impact of threats related to coastal development and fisheries. Over the course of five years, we developed practical research methods and trained local scientists in Thailand to use accepted line transect distance sampling methods for abundance assessment. The study focused on a little-known coastal and freshwater species found throughout Southeast Asia, namely the Irrawaddy dolphin, which has been sighted regularly along the coast of the eastern Gulf of Thailand. During five years of line transect boat surveys in Trat Province, the eastern-most province in Thailand, we found an average of 423 dolphins distributed within 12km of the coast. Compared to other abundance estimates of coastal Irrawaddy dolphins in Southeast Asia, this is a relatively large number. This population could extend into the northern coast of Cambodia, where surveys are currently being planned. The Thai government has begun talks with Cambodia about a transboundary marine protected area that would include areas in both countries where coastal Irrawaddy dolphins are found. Other analyses include photo-identification, modeling environmental factors that determine presence, determination of fresh vs. salt water foraging using stable isotopes, and an assessment of threats. Collaboration between scientists in Thailand, Cambodia and Vietnam is further needed to determine dolphin movement and habitat use across borders.

    Transition metal-pnictide compounds have received attention for their tendency to combine magnetism and unconventional superconductivity. Binary CoAs lies on the border of paramagnetism and the more complex behavior seen in isostructural CrAs, MnP, FeAs, and FeP. Here we report the properties of CoAs single crystals grown with two distinct techniques along with density functional theory calculations of its electronic structure and magnetic ground state. While all indications are that CoAs is paramagnetic, both experiment and theory suggest proximity to a ferromagnetic instability. Quantum oscillations are seen in torque measurements up to 31.5 T and support the calculated paramagnetic Fermiology.

    To report a series of macula-sparing rhegmatogenous retinal detachments (MSRRDs) treated with demarcation laser photocoagulation (DLP). Retrospective, noncomparative case series. Thirty-one patients (34 eyes) with primary or recurrent MSRRDs without associated visual field loss, necrotizing retinitis, or proliferative vitreoretinopathy (PVR), managed with DLP from November 1992 through May 1999. Demarcation laser photocoagulation consisting of a triple row of confluent laser burns. Best corrected postoperative visual acuity and MSRRD progression or recurrence. Thirty-four primary and recurrent MSRRDs were treated by DLP, which consisted of a triple row of confluent laser burns. Macula-sparing rhegmatogenous retinal detachments were located in all quadrants and affected 10% to 45% of the retina. Findings associated with MSRRDs included lattice degeneration (12 eyes), vitreous hemorrhage (4 eyes), and demarcation line (9 eyes). Symptoms (photopsias or floaters) were associated with 14 MSRRDs. Eight eyes were myopic and 11 were pseudophakic. Thirty-two MSRRDs were shallow, two were dome shaped, and all were smooth without corrugations. Follow-up ranged from 1.5 to 80 months (mean, 15.8 months; median, 17 months). Thirty-three of 34 detachments remained stable after DLP. Three flattened spontaneously. One eye was managed with scleral buckle 6 weeks after DLP. Progression was attributed to incomplete laser treatment. Best corrected postoperative visual acuity was the same or improved in all but one eye, in which a cataract developed. Demarcation laser photocoagulation is an effective method to manage acute or chronic, primary or recurrent MSRRDs without associated PVR that are shallow and smooth without corrugations. Demarcation laser photocoagulation is an alternative to both observation and surgical repair for these select MSRRDs.

    This paper discusses a paraffin dispersant (in seawater) application to clean paraffin deposition from a severely restricted 17.4-mile dual subsea flow line system in the Gulf of Mexico Cottonwood development. In principle, dispersant treatments are simple processes requiring effective dispersant packages and agitation to break-up and disperse deposition. Dispersants have been used onshore for treating wax deposition for decades. Implementation of a treatment in a long deep water production system, however, poses numerous challenges. The Cottonwood application was one of the first ever deep water dispersant applications. The application was designed in four separate phases: pre-treatment displacement for hydrate protection, dispersant treatment for paraffin deposition removal, pigging sequence for final flow line cleaning, and post-treatment displacement for hydrate protection. In addition, considerable job planning was performed to ensure the application was executed in a safe and environmentally responsible manner. Two dynamically positioned marine vessels were used for pumping fluids and capturing returns. The application was extremely successful in restoring the deep water flow lines back to near pre-production state. Final pigging operations confirmed the flow lines were cleaned of all restrictions. Significant paraffin deposition was removed in the application. Approximately 900 bbls of paraffin sludge was recovered from the 4000 bbl internal volume flow line loop. Furthermore, the application was completed with zero discharge of fluids. The application provided significant value for the Cottonwood development. It allowed production from wells to be brought on-line at a higher capacity, thereby generating increased revenue. It also allowed resumption of routine pigging operations. As such, the Cottonwood dispersant application illustrates that with proper planning and execution, paraffin dispersant treatments can be highly effective solutions for cleaning

  11. Fast semi-automated lesion demarcation in stroke

    Full Text Available Lesion–behaviour mapping analyses require the demarcation of the brain lesion on each (usually transverse slice of the individual stroke patient's brain image. To date, this is generally thought to be most precise when done manually, which is, however, both time-consuming and potentially observer-dependent. Fully automated lesion demarcation methods have been developed to address these issues, but these are often not practicable in acute stroke research where for each patient only a single image modality is available and the available image modality differs over patients. In the current study, we evaluated a semi-automated lesion demarcation approach, the so-called Clusterize algorithm, in acute stroke patients scanned in a range of common image modalities. Our results suggest that, compared to the standard of manual lesion demarcation, the semi-automated Clusterize algorithm is capable of significantly speeding up lesion demarcation in the most commonly used image modalities, without loss of either lesion demarcation precision or lesion demarcation reproducibility. For the three investigated acute datasets (CT, DWI, T2FLAIR, containing a total of 44 patient images obtained in a regular clinical setting at patient admission, the reduction in processing time was on average 17.8 min per patient and this advantage increased with increasing lesion volume (up to 60 min per patient for the largest lesion volumes in our datasets. Additionally, our results suggest that performance of the Clusterize algorithm in a chronic dataset with 11 T1 images was comparable to its performance in the acute datasets. We thus advocate the use of the Clusterize algorithm, integrated into a simple, freely available SPM toolbox, for the precise, reliable and fast preparation of imaging data for lesion–behaviour mapping analyses.

  15. Physical macroeconomics: a demarcation of accounting and analysis

    Energy Technology Data Exchange (ETDEWEB)

    Hahn, M. de [Statistics Netherlands, Voorburg (Netherlands)

    2001-07-01

    This paper provides a general discussion on physical flow accounting methodology. The discussion is limited to those methods primarily applied to the national economy level. Specific attention is given to the demarcation of accounting versus analysis. The primary goal of statistics and accounting is to provide an acceptable level of 'descriptiveness' and 'neutrality' in its representation of facts. On the other hand, modelling or analysis usually relies on assumptions of a much wider scale, for example in relation to human behaviour, or by the necessity of ceteris paribus clauses in partial analysis. While accounting usually provides answers on past events, analysis is often ex-ante oriented. A number of accounting methods are reviewed on the basis of their accounting scopes and indicator proposals. In general the accounting frameworks are rather complementary or at least not contradictory but inconsistencies emerge in some of the indicators that are derived from the accounts. The paper further elaborates on the significance of the national accounts in this field of research. National accounting concepts and definitions contributes to a sound demarcation of the (national) economy, which appears equally valid for physical representations of a national economy. This demarcation also supports the sound allocation of environmental burdens to specific national or regional economies. At the same time, the economic relevance of physical flows is to a large extent exposed by their connection to specific economic (production and consumption) processes and concomitant transactions. This linkage, as for example accommodated in a National Accounting Matrix including Environmental Accounts (NAMEA) provides in this respect a useful statistical framework that provides a consistent comparison of environmental burdens to economic benefits (or environmental benefits to economic costs)

    The demarcation membrane system (DMS) in megakaryocytes forms the plasma membrane (PM) of future platelets. Using confocal microscopy, electron tomography, and large volume focused ion beam/scanning electron microscopy (FIB/SEM), we determined the sequential steps of DMS formation. We identified a pre-DMS that initiated at the cell periphery and was precisely located between the nuclear lobes. At all developmental stages, the DMS remained continuous with the cell surface. The number of these connections correlated well with the nuclear lobulation, suggesting a relationship with cleavage furrow formation and abortive cytokinesis. On DMS expansion, Golgi complexes assembled around the pre-DMS, and fusion profiles between trans-golgi network-derived vesicles and the DMS were observed. Brefeldin-A reduced DMS expansion, indicating that the exocytic pathway is essential for DMS biogenesis. Close contacts between the endoplasmic reticulum (ER) and the DMS were detected, suggesting physical interaction between the 2 membrane systems. FIB/SEM revealed that the DMS forms an intertwined tubular membrane network resembling the platelet open canalicular system. We thus propose the following steps in DMS biogenesis: (1) focal membrane assembly at the cell periphery; (2) PM invagination and formation of a perinuclear pre-DMS; (3) expansion through membrane delivery from Golgi complexes; and (4) ER-mediated lipid transfer.

  17. Distribution of natural radionuclides and uranium activity ratio in Gulf of Thailand sediments as base line data

    This paper reports distribution of naturally occurring radionuclides and uranium activity ratio in marine sediments from selected coast, along the Gulf of Thailand to establish baseline data. Thailand has a plan to construct nuclear power plants (NPPs) as well as coal-fired thermal power plants to generate adequate and reliable electricity supply for rapid growth of industrialization. Therefore, it is important to focus not only on security and adequacy of power system but also on environmental protection and monitoring and risk assessment. To carry out environmental monitoring, baseline data plays a significant role. These data should be established and available before set up of mega projects that could impact the environment and health. Therefore, we have collected samples from five areas in the Gulf of Thailand, which are proposed as potential sites, to set up power plants by Thailand government. A total number of fifty-four marine sediment samples were collected. Gamma spectroscopy was used to determine the concentration of natural radionuclides e.g. {sup 226}Ra, {sup 228}Ac and {sup 40}K. Activity concentrations of {sup 226}Ra, {sup 228}Ac and {sup 40}K vary from 2.91-67.17 Bq/kg with an average of 26.64±14.57 Bq/kg, 4.42-109.17 Bq/kg with an average of 43.79±23.92 Bq/kg and 3.36-1004.56 Bq/kg with an average of 393.56±208.04 Bq/kg, respectively. The radiation hazard parameters including absorbed dose rate (D), annual effective dose equivalent (AEDE), radium equivalent activity (AGDE) and external hazard index (Hex) were calculated and compared with the international recommended values. We have noticed that sediments from two sites characterized by similar geological nature of landforms with a rocky coast have higher concentration of natural radionuclides. Concentration of uranium was determined using the inductively coupled plasma mass spectrometry (ICP-MS) and isotopic composition of {sup 234}U/{sup 238}U and {sup 235}U/{sup 238}U were determined using

    Full Text Available RESUMEN La pertenencia al lugar, la necesidad de significarse como colectividad, han sido una constante de la arquitectura a lo largo de la historia. La demarcación de un recinto, la definición de un interior en contraposición a un exterior, ha seguido estrategias diversas. De las necesidades defensivas se derivan empalizadas, vallados y murallas. Del anhelo simbólico y conmemorativo, los elementos verticales, menhires, obeliscos y torres. Estas metodologías han evolucionado para adaptarse a la escala de la metrópolis contemporánea. La nueva dimensión urbana impide la construcción de un objeto material continuo, que pasa a ser evocado por una sucesión de fragmentos referenciales. Por otra parte, la explosión de la movilidad conlleva el difuminado de los límites del área urbana, encontrando en sus redes de transporte el nuevo aglutinante del colectivo. SUMMARY The relevance to the place, the need to signify itself as a whole, has been anarchitectural constant throughout history. The demarcation of an enclosure, the definition of an interior in contrast to an exterior, has followed diverse strategies. Palisades, stockades and walls were derived from defensive needs; the vertical elements, menhirs, obelisks and towers, from the desire for symbolism and commemoration. These methodologies have evolved to adapt to the scale of the contemporary metropolis. The new urban dimension impedes the construction of a continuous material object, which happens to be evoked by a succession of referential fragments. On the other hand, the explosion of urban mobility entails the blurring of the limits of the urban area, with the new cohesiveness of the group being provided by its transport networks.

    This paper problematizes the assumption that the essence of ‘game’ and ‘play’ can somehow be distilled into a set of necessary and sufficient conditions for a phenomenon to be demarcated as ‘game’ and ‘play’. This is the notion that it is possible to come up with a definition of the necessary...... necessarily excludes games and types of play that fall outside of the proposed demarcation in question. There is no one essential common feature to all demarcated phenomena, but they are defined by overlapping similarities, or what Wittgenstein termed ‘family resemblances’.

    In a scale-free network, only a minority of nodes are connected very often, while the majority of nodes are connected rarely. However, what is the ratio of minority nodes to majority nodes resulting from the Matthew effect? In this paper, based on a simple preferential random model, the poor-rich demarcation points are found to vary in a limited range, and form a poor-rich demarcation interval that approximates to k/m in [3,4]. As a result, the (cumulative) degree distribution of a scale-free network can be divided into three intervals: the poor interval, the demarcation interval and the rich interval. The inequality of the degree distribution in each interval is measured. Finally, the Matthew effect is applied to the ABC analysis of project management. (general)

    Full Text Available The perception of elements in a system often creates their interdependence, interconditionality, and suppression. The lines from a basic geometrical element have become the model of a reductive world based on isolation according to certain criteria such as function, structure, and social organization. Their traces are experienced in the contemporary world as fragments or ruins of a system of domination of an assumed hierarchical unity. How can one release oneself from such dependence or determinism? How can the lines become less “systematic” and forms more autonomous, and less reductive? How is a form released from modernistic determinism on the new controversial ground? How can these elements or forms of representation become forms of action in the present complex world? In this paper, the meaning of lines through the ideas of Le Corbusier, Leonidov, Picasso, and Hitchcock is presented. Spatial research was made through a series of examples arising from the projects of the architectural studio “Residential Transformations”, which was a backbone for mapping the possibilities ranging from playfulness to exactness, as tactics of transformation in the different contexts of the contemporary world.

  4. Delineation of frost characteristics on cold walls by using a new formula for psychrometrics demarcation boundary

    2009-01-01

    In this study, a direct formula that predicts either the frost formation on cold walls is correspondence to psychrometric-subsaturated or supersaturated regions is presented. The developed formula uses the data of the entering air dry-bulb temperature and absolute humidity, and the absolute humidity of the air at saturation corresponding to the coil surface temperature. Cases studies of demarcation criteria for frost formation on evaporator coil using experimental measured data, and on walls of cold storage freezer using measured data from literature are used to validate the formula and it is found that results are completely matches to the graphic plot of the data on the psychrometric chart. In case of cold storage freezers, the result clearly shows that a greater demarcation criteria value indicates frost formation under sever condition that is characterized as snow-like with low density and thermal conductivity.

  5. "Bewitching" or confusing methaphysics? The demarcation between science and metaphysics according to Karl Popper

    Directory of Open Access Journals (Sweden)

    M. Elaine Botha

    1986-03-01

    Full Text Available The problems of both classical and modern theory of knowledge, according to Popper, reside in the problem of demarcation: a problem closely re­ lated to the problem of induction. The paper argues the view that Popper's view of metaphysics is ambiguous, requiring another criterion to distinguish between "good " and "bad " metaphysics. The sources of the problem are pinpointed, and Popper's distinction between three types of theory outlined. The article then explores the distinction between types of theories and the issues of falsification, testability and refutation, before going on to a consideration of the relationship between science and metaphysics, and w eighing up the issue of good ancid metaphysics. From this emerges clearly that the second "criterionot demarcation" is needed to make precisely this distinction; also in view of Popper's u n ­ clear, even ambiguous, view of metaphysics.

    The nucleolus, the ribosomal factory of the cell, has emerged as a key player that regulates many aspects of cell biology. Several thousand proteins associate at least transiently with nucleoli, thereby generating a highly dynamic compartment with a protein profile which is sensitive to changes in cell physiology and pharmacological agents. Powerful tools that reliably demarcate the nucleoli are a prerequisite to measure their composition and activities. Previously, we developed quantitative methods to measure fluorescently labeled molecules in nucleoli. While these tools identify nucleoli under control and mild stress conditions, the accurate detection of nucleolar boundaries under harsh experimental conditions is complicated by the lack of appropriate markers for the nucleolar compartment. Using fluorescence microscopy we have now identified new marker proteins to detect nucleoli upon (a) severe stress and (b) drug treatments that trigger a pronounced reorganization of nucleoli. Our results demonstrate that nucleolin is an ideal marker to delimit nucleoli when cells are exposed to heat or oxidative stress. Furthermore, we show for the first time that cellular apoptosis susceptibility protein (CAS) and human antigen R protein (HuR) are excluded from nucleoli and can be employed to delimit these compartments under severe conditions that redistribute major nucleolar proteins. As proof-of-principle, we used these markers to demarcate nucleoli in cells treated with pharmacological compounds that disrupt the nucleolar organization. Furthermore, to gain new insights into the biology of the nucleolus, we applied our protocols and quantified stress- and drug-induced changes in nucleolar organization and function. Finally, we show that CAS, HuR and nucleolin not only identify nucleoli in optical sections, but are also suitable to demarcate the nucleolar border following 3D reconstruction. Taken together, our studies present novel marker proteins that delimit nucleoli with

Our results demonstrate that nucleolin is an ideal marker to delimit nucleoli when cells are exposed to heat or oxidative stress. Furthermore, we show for the first time that cellular apoptosis susceptibility protein (CAS and human antigen R protein (HuR are excluded from nucleoli and can be employed to delimit these compartments under severe conditions that redistribute major nucleolar proteins. As proof-of-principle, we used these markers to demarcate nucleoli in cells treated with pharmacological compounds that disrupt the nucleolar organization. Furthermore, to gain new insights into the biology of the nucleolus, we applied our protocols and quantified stress- and drug-induced changes in nucleolar organization and function. Finally, we show that CAS, HuR and nucleolin not only identify nucleoli in optical sections, but are also suitable to demarcate the nucleolar border following 3D reconstruction. Taken together, our studies present novel marker proteins that

    In engineering applications, components often experience cyclic loading and therefore, have crack initiation propagation phase. In this research work experimental demarcation of fatigue crack initiation has been investigated. Initiation phase of fatigue life of Aluminium was determined by using single and two step fatigue loading test on four point rotating bending fatigue testing machine. Experimental data is used to determine the distinction between the initiation and propagation phase. Initiation phase is determined at different stress levels. The obtained results demonstrate the effect of stress level on initiation phase and propagation phase. (author)

    As it became a non‐permanent member of the UN Security Council in January 2003, Germany stepped up its opposition to war with Iraq. The stage was set for a repeat of Germany's uncomfortable position during the 1991 Gulf War. At that time, as most of Germany's allies rallied behind Washington......, Germany made only financial contributions, and hundreds of thousands of Germans took to the streets to protest against the war. Yet, since 1991, Germany had come a long way in its attitudes towards military force. From a policy of complete abstention from military deployments beyond NATO's area (so...

  11. The ends of medical intervention and the demarcation of the normal from the pathological.

    2000-10-01

    This study examines the ends of medical intervention and argues that mainstream contemporary medicine assumes that appropriate ends may be discovered (i.e., naturalism), rather than created or decided upon (i.e., conventionalism). The essay then applies these considerations to the problem of the demarcation of the normal from the pathological. I argue that the common formulations of this dispute commit a fallacy, as they characterize the "normal" as a state of the organism and not as an ongoing process within it. Such a process may be characterized as self-creation and self-repair. Such considerations support the conclusion that normality may be regarded as a regulative idea, rather than as an end-state, and as part of the ends of medical intervention, depending upon choice and context.

    2007-12-01

    Previous research has documented students' conceptual difficulties learning evolution and how student learning may be related to students' views of evolution and science. This mixed methods study addressed how 74 high school biology students from six Indiana high schools viewed their evolution learning experiences, the demarcations of science from non-science, and evolution understanding and acceptance. Data collection entailed qualitative and quantitative methods including interviews, classroom observations, surveys, and assessments to address students' views of science and non-science, evolution learning experiences, and understanding and acceptance of evolution. Qualitative coding generated several demarcation and evolution learning experience codes that were subsequently used in quantitative comparisons of evolution understanding and acceptance. The majority of students viewed science as empirical, tentative but ultimately leading to certain truth, compatible with religion, the product of experimental work, and the product of human creativity. None of the students offered the consensus NOS view that scientific theories are substantiated explanations of phenomena while scientific laws state relationships or patterns between phenomena. About half the students indicated that scientific knowledge was subjectively and socio-culturally influenced. The majority of students also indicated that they had positive evolution learning experiences and thought evolution should be taught in secondary school. The quantitative comparisons revealed how students who viewed scientific knowledge as subjectively and socio-culturally influenced had higher understanding than their peers. Furthermore, students who maintained that science and religion were compatible did not differ with respect to understanding but had higher acceptance than their peers who viewed science and religion as conflicting. Furthermore, students who maintained that science must be consistent with their

    Full Text Available Abstract Background Several studies have highlighted the importance of collective social factors for population health. One of the major challenges is an adequate definition of the spatial units of analysis which present properties potentially related to the target outcomes. Political and administrative divisions of urban areas are the most commonly used definition, although they suffer limitations in their ability to fully express the neighborhoods as social and spatial units. Objective This study presents a proposal for defining the boundaries of local neighborhoods in Rio de Janeiro city. Local neighborhoods are constructed by means of aggregation of contiguous census tracts which are homogeneous regarding socioeconomic indicators. Methodology Local neighborhoods were created using the SKATER method (TerraView software. Criteria used for socioeconomic homogeneity were based on four census tract indicators (income, education, persons per household, and percentage of population in the 0-4-year age bracket considering a minimum population of 5,000 people living in each local neighborhood. The process took into account the geographic boundaries between administrative neighborhoods (a political-administrative division larger than a local neighborhood, but smaller than a borough and natural geographic barriers. Results The original 8,145 census tracts were collapsed into 794 local neighborhoods, distributed along 158 administrative neighborhoods. Local neighborhoods contained a mean of 10 census tracts, and there were an average of five local neighborhoods per administrative neighborhood. The local neighborhood units demarcated in this study are less socioeconomically heterogeneous than the administrative neighborhoods and provide a means for decreasing the well-known statistical variability of indicators based on census tracts. The local neighborhoods were able to distinguish between different areas within administrative neighborhoods

    2018-04-01

    Full Text Available Current morphometric methods that comprehensively measure shape cannot compare the disparate leaf shapes found in seed plants and are sensitive to processing artifacts. We explore the use of persistent homology, a topological method applied as a filtration across simplicial complexes (or more simply, a method to measure topological features of spaces across different spatial resolutions, to overcome these limitations. The described method isolates subsets of shape features and measures the spatial relationship of neighboring pixel densities in a shape. We apply the method to the analysis of 182,707 leaves, both published and unpublished, representing 141 plant families collected from 75 sites throughout the world. By measuring leaves from throughout the seed plants using persistent homology, a defined morphospace comparing all leaves is demarcated. Clear differences in shape between major phylogenetic groups are detected and estimates of leaf shape diversity within plant families are made. The approach predicts plant family above chance. The application of a persistent homology method, using topological features, to measure leaf shape allows for a unified morphometric framework to measure plant form, including shapes, textures, patterns, and branching architectures.

  19. Demarcation of the ethics of care as a discipline: discussion article.

    2014-11-01

    This article aims to initiate a discussion on the demarcation of the ethics of care. This discussion is necessary because the ethics of care evolves by making use of insights from varying disciplines. As this involves the risk of contamination of the care ethical discipline, the challenge for care ethical scholars is to ensure to retain a distinct care ethical perspective. This may be supported by an open and critical debate on the criteria and boundaries of the ethics of care. As a contribution, this article proposes a tentative outline of the care ethical discipline. What is characteristic of this outline is the emphasis on relational programming, situation-specific and context-bound judgments, a political-ethical perspective, and empirical groundedness. It is argued that the ethics of care is best developed further by means of an intradisciplinary approach. Two intradisciplinary examples show how within the frame of one discipline, other disciplines are absorbed, both with their body of knowledge and their research methodology. © The Author(s) 2013.

  20. The demarcation of arbitrary boundaries for coastal zone management: the Israeli case.

    Sas, Eliraz; Fischhendler, Itay; Portman, Michelle E

    2010-11-01

    Integrated coastal zone management (ICZM) addresses the interconnections, complexities, and conflicts between many users of the coastal area with different goals. It requires setting managerial boundaries that capture many elements of human and natural systems. Experience teaches us that without a directed effort managerial rules and laws are not likely to coincide with the physical sensitivity of units that reflect different environmental characteristics of the coastal zone. Hence the aim of this study is to explore why coastal managerial boundaries are set arbitrarily and whether and how it is possible to address the problems this poses. We examine what influences the decisions of a new coastal management authority in Israel to determine how this body overcomes the limits of arbitrary boundary demarcation. The study found that real life management succeeded to both address areas outside the arbitrary boundaries and also to respect some of the different socio-economic needs and physical constraints of the coastal sub-units. Israel's Coastal Environment Protection Law allows and, in fact, encourages the regulator to use discretion and to employ various criteria to balance development and conservation. This implies that policy makers are cognizant of a need to balance ecologically-sensitive boundaries that consider the homogeneity of the coast with politically feasible boundaries that are set arbitrarily.

    Tumor heterogeneity is a crucial area of cancer research wherein inter- and intra-tumor differences are investigated to assess and monitor disease development and progression, especially in cancer. The proliferation of imaging and linked genomic data has enabled us to evaluate tumor heterogeneity on multiple levels. In this work, we examine magnetic resonance imaging (MRI) in patients with brain cancer to assess image-based tumor heterogeneity. Standard approaches to this problem use scalar summary measures (e.g., intensity-based histogram statistics) that do not adequately capture the complete and finer scale information in the voxel-level data. In this paper, we introduce a novel technique, DEMARCATE (DEnsity-based MAgnetic Resonance image Clustering for Assessing Tumor hEterogeneity) to explore the entire tumor heterogeneity density profiles (THDPs) obtained from the full tumor voxel space. THDPs are smoothed representations of the probability density function of the tumor images. We develop tools for analyzing such objects under the Fisher-Rao Riemannian framework that allows us to construct metrics for THDP comparisons across patients, which can be used in conjunction with standard clustering approaches. Our analyses of The Cancer Genome Atlas (TCGA) based Glioblastoma dataset reveal two significant clusters of patients with marked differences in tumor morphology, genomic characteristics and prognostic clinical outcomes. In addition, we see enrichment of image-based clusters with known molecular subtypes of glioblastoma multiforme, which further validates our representation of tumor heterogeneity and subsequent clustering techniques.

    2014-01-01

    Full Text Available The article focuses on the problem of determination of public and private in the post­soviet area. Formation of these spheres should be a logical conclusion of successful transformation and modernization process in ex­soviet republics and getting all spheres of civil life out of the state control. Historical specific is underlined; it is given the determination and main characteristics of public and private. It is given two main approaches’ ways of interpretation the phenomena and formation of public sphere according to H. Arendt and Ju. Hubermas. The specific of formation and demarcation of public and private spheres in the post­soviet area is analyzed. The boundaries between public and private spheres were deformed by the soviet state and communist society. As a result it was built hierarchical relations among the state, society and ruler; it is typical for power centralized societies. The determining factor of institutional heritage in the processes of state­making is underlined. The deformation of division of state, public and private spheres is caused by combining of traditional and modern institutes and practices; as a result social practices that are against of logic of modern society slow down the development of market­oriented economy and modernization of institutions.

  5. First application of liquid-metal-jet sources for small-animal imaging: High-resolution CT and phase-contrast tumor demarcation

    Larsson, Daniel H.; Lundstroem, Ulf; Burvall, Anna; Hertz, Hans M. [Department of Applied Physics, KTH Royal Institute of Technology/Albanova, 10691 Stockholm (Sweden); Westermark, Ulrica K.; Arsenian Henriksson, Marie [Department of Microbiology, Tumor and Cell Biology (MTC), Karolinska Institutet, 17177 Stockholm (Sweden)

    2013-02-15

    Purpose: Small-animal studies require images with high spatial resolution and high contrast due to the small scale of the structures. X-ray imaging systems for small animals are often limited by the microfocus source. Here, the authors investigate the applicability of liquid-metal-jet x-ray sources for such high-resolution small-animal imaging, both in tomography based on absorption and in soft-tissue tumor imaging based on in-line phase contrast. Methods: The experimental arrangement consists of a liquid-metal-jet x-ray source, the small-animal object on a rotating stage, and an imaging detector. The source-to-object and object-to-detector distances are adjusted for the preferred contrast mechanism. Two different liquid-metal-jet sources are used, one circulating a Ga/In/Sn alloy and the other an In/Ga alloy for higher penetration through thick tissue. Both sources are operated at 40-50 W electron-beam power with {approx}7 {mu}m x-ray spots, providing high spatial resolution in absorption imaging and high spatial coherence for the phase-contrast imaging. Results: High-resolution absorption imaging is demonstrated on mice with CT, showing 50 {mu}m bone details in the reconstructed slices. High-resolution phase-contrast soft-tissue imaging shows clear demarcation of mm-sized tumors at much lower dose than is required in absorption. Conclusions: This is the first application of liquid-metal-jet x-ray sources for whole-body small-animal x-ray imaging. In absorption, the method allows high-resolution tomographic skeletal imaging with potential for significantly shorter exposure times due to the power scalability of liquid-metal-jet sources. In phase contrast, the authors use a simple in-line arrangement to show distinct tumor demarcation of few-mm-sized tumors. This is, to their knowledge, the first small-animal tumor visualization with a laboratory phase-contrast system.

    The main proposal to set up an articulated mode of operation of health services has been the concept of network, which has been appropriated in different ways in the field of public health, as it is used in other disciplinary fields or even taking it from common sense. Amid the diversity of uses and concepts, we recognize the need for rigorous conceptual demarcation about networks in the field of health. Such concern aims to preserve the strategic potential of this concept in the research and planning in the field, overcoming uncertainties and distortions still observed in its discourse-analytic circulation in public health. To this end, we will introduce the current uses of network in different disciplinary fields, emphasizing dialogues with the field of public health. With this, we intend to stimulate discussions about the development of empirical dimensions and analytical models that may allow us to understand the processes produced within and around health networks. RESUMO A principal proposta para configurar um modo articulado de funcionamento dos serviços de saúde tem sido o conceito de rede, que vem sendo apropriado de diferentes formas no campo da saúde coletiva, conforme seu emprego em outros campos disciplinares ou mesmo tomando-o do senso comum. Em meio à pluralidade de usos e concepções, reconhecemos a necessidade de rigorosa demarcação conceitual acerca de redes no campo da saúde. Tal preocupação visa a preservar o potencial estratégico desse conceito na investigação e planificação no campo, superando precariedades e distorções ainda observadas em sua circulação discursivo-analítica na saúde coletiva. Para tanto, apresentaremos os usos correntes de rede em diferentes campos disciplinares, destacando interlocuções com o campo da saúde coletiva. Com isso, pretendemos estimular o debate acerca do desenvolvimento de dimensões empíricas e modelos de análise que permitam compreender os processos produzidos no interior e ao redor

The hurricane struck South Florida Aug. 4, churned west into the gulf, then swung north and hit the South Louisiana coast Aug. 5. By the close of business Sept. 8 MMS had received damage reports covering 83 pipeline segments and 193 platforms and satellite installations. MMS last week estimated about 500 MMcfd of gas production had been restored in the gulf and 100,000-150,000 b/d of oil. Production still lost as a result of Andrew was estimated at 2-2.5 bcfd of gas and 90,000-120 b/d of oil.

    Ahlqvist, J.B.; Isberg, A.M.

    1998-01-01

    Purpose: To study the CT depiction of bone demarcations in the temporomandibular joint, using conventional window level and window width; and to evaluate observer performance in estimating bone thickness in these images. Material and Methods: Seven joint specimens were imaged by CT and then cryosectioned. The measurements of bone wall thickness in the images were compared to the true bone thickness at each cutting level. In addition, 4 experienced radiologists estimated the thickness of the bone walls in the images. Results: The relative difference between the CT reproduction and the true bone thickness was small for bone walls thicker than 2 mm. This difference increased with the decrease in bone thickness and the increase in the inclination of the bone wall from the perpendicular to the image plane. Bone walls thinner than 1 mm were reproduced as considerably thicker than their true thickness. This resulted in a clinical overestimation of bone thickness. Conclusion: Both the CT representation and the interpretation of bone demarcation in the temporomandibular joint may constitute a problem. Partial volume averaging effects can result in an overestimation of bone dimensions amounting to 200% for thin bones. The central white zone in images of thin bone walls obtained with the parameters described here could serve as an indicator that could help to reduce the risk of overestimating bone thickness.

    This paper gives an environmental damage report for the Kuwait-Persian Gulf area that has been affected by the Gulf War oil well fires and the release of oil into the sea. The report was prepared by members of an ENEA (Italian Commission for New Technologies, Energy and the Environment)/Friends of the Earth scientific mission whose aim was to assess the damage to terrestrial and aquatic ecosystems and to develop short and long terms programs of damage containment and environmental restoration. With regard to shore-line clean-up operations, the mission noted the scarce use of manpower, 500 versus 11,000 for the Exxon Valdez spill. Seventy-five per cent of the surface of Kuwait has been covered with a fine spray of petroleum and ashes borne by turbulent winds.

    Background Large-scale genome rearrangements brought about by chromosome breaks underlie numerous inherited diseases, initiate or promote many cancers and are also associated with karyotype diversification during species evolution. Recent research has shown that these breakpoints are nonrandomly distributed throughout the mammalian genome and many, termed "evolutionary breakpoints" (EB), are specific genomic locations that are "reused" during karyotypic evolution. When the phylogenetic trajectory of orthologous chromosome segments is considered, many of these EB are coincident with ancient centromere activity as well as new centromere formation. While EB have been characterized as repeat-rich regions, it has not been determined whether specific sequences have been retained during evolution that would indicate previous centromere activity or a propensity for new centromere formation. Likewise, the conservation of specific sequence motifs or classes at EBs among divergent mammalian taxa has not been determined. Results To define conserved sequence features of EBs associated with centromere evolution, we performed comparative sequence analysis of more than 4.8 Mb within the tammar wallaby, Macropus eugenii, derived from centromeric regions (CEN), euchromatic regions (EU), and an evolutionary breakpoint (EB) that has undergone convergent breakpoint reuse and past centromere activity in marsupials. We found a dramatic enrichment for long interspersed nucleotide elements (LINE1s) and endogenous retroviruses (ERVs) and a depletion of short interspersed nucleotide elements (SINEs) shared between CEN and EBs. We analyzed the orthologous human EB (14q32.33), known to be associated with translocations in many cancers including multiple myelomas and plasma cell leukemias, and found a conserved distribution of similar repetitive elements. Conclusion Our data indicate that EBs tracked within the class Mammalia harbor sequence features retained since the divergence of marsupials

Fifteen years after the Constitution was approved, this process of delineation has been slow and misleading. This delay has caused that in the present, these human beings groups are being stalked by outside interests (illegal mining, development projects, irregular forces, among others who threaten their existence as distinct cultures; since the right to territory is a fundamental human right for their survival. This article is the result of a field research. In the first part, the study analyzes the Organic Law of Indigenous Peoples and Communities (LOPCI (2005 in Venezuela, with the purpose of clarifying at what stage the territorial demarcation process is paralyzed; and as a result, it describes how many communities and indigenous peoples have been demarcated and entitled from 2005 to 2014.

  20. Tides and seiches in gulfs

    International Nuclear Information System (INIS)

    Pierini, S.

    1981-01-01

    In this paper Garrett's theory of tides in gulfs is extended so that its formalism includes the free oscillations (seiches) of the gulf. The elevation of the free surface zeta and the velocity field u are obtained in a rectangular, one-dimensional gulf opening into an infinite ocean. An application of the results to the Adriatic sea can explain qualitatively the long life of the uninodal seiche of that basin. (author)

  1. What are genres good for? Divisions, demarcations and classifications in structural and cognitive anthropology, on the example of music culture

    Directory of Open Access Journals (Sweden)

    Bojan Žikić

    2016-02-01

    Full Text Available Levi-Strauss’s theoretical-methodological "legatee" – anthropological structuralism was one of the most important theoretical frameworks used in cognitive anthropology. Since it was sometimes too abstract for ‘practical’ minds, trained in British-American empirical traditions, Levi-Strauss thought was mediated through the works of British structural-functionalist, particularly those of Mary Douglas and Edmund Leach, who established its premises as a kind of contextualised particularism of the unquestioned universalism. Ideas about the way in which human cultural mind functions, is one of the corner stones of cognitive anthropology, which cognitive anthropology shares with structural anthropology, and from which cognitive anthropology actually inherits what it shares with structural anthropology – this sounds properly structural – that is: an interest in the processes of division, demarcation and classification in a sense of cultural management of a perceived surrounding reality. An example for such analysis, that I use in this paper, is music, or more precisely music culture, an expression that I use in order to imply that the affinity to a type of music, or musical genre should be understood in a sense of a particular cultural way of thinking and acting.

  2. Gulf operators resuming production

    International Nuclear Information System (INIS)

    Koen, A.D.

    1992-01-01

    This paper reports that Gulf of Mexico operators last week were gradually restoring production at installations struck by Hurricane Andrew. The Minerals Management Service continued receiving reports of more damage. By the end of the day Sept. 8, MMS had received reports of damage to 83 pipeline segments and 193 platforms and satellite installations. Damage reports listed 112 installations with structural damage, 13 platforms toppled and five leaning, and 30 satellite platforms toppled and 33 leaning. But despite the extent of damage the storm inflicted on oil and gas installations in the gulf, it pales in comparison to the misery and suffering the storm caused in Florida and Louisiana, an oil company official said

    1992-01-01

    This paper reports that reports of damage by Hurricane Andrew escalated last week as operators stepped up inspections of oil and gas installations in the Gulf of Mexico. By midweek, companies operating in the gulf and South Louisiana were beginning to agree that earlier assessments of damage only scratched the surface. Damage reports included scores of lost, toppled, or crippled platforms, pipeline ruptures, and oil slicks. By midweek the U.S. coast Guard had received reports of 79 oil spills. Even platforms capable of resuming production in some instances were begin curtailed because of damaged pipelines. Offshore service companies the another 2-4 weeks could be needed to fully assess Andrew's wrath. Lack of personnel and equipment was slowing damage assessment and repair

  4. Hurricane shuts down gulf activity

    Koen, A.D.

    1992-01-01

    This paper reports that producers in the Gulf of Mexico and plant operators in South Louisiana last week were checking for damage wrought by Hurricane Andrew. In its wake Andrew left evacuated rigs and platforms in the gulf and shuttered plants across a wide swath of the Gulf Coast. Operations were beginning to return to normal late last week. Not all gulf operators, especially in the central gulf, expected to return to offshore facilities. And even producers able to book helicopters did not expect to be able to fully assess damage to all offshore installations before the weekend. MMS officials in Washington estimated that 37,500 offshore workers were evacuated from 700 oil and gas installations on the gulf's Outer Continental Shelf. Gulf oil and gas wells account for about 800,000 b/d of oil and one fourth of total U.S. gas production. MMS was awaiting an assessment of hurricane damage before estimating how soon and how much gulf oil and gas production would be restored

  5. Relationship between caries experience and demarcated hypomineralised lesions (including MIH) in the permanent dentition of 15-year-olds.

    This cross-sectional study compared the caries experience in 15-year-olds with and without demarcated hypomineralised lesions (DHL) in permanent teeth. One thousand three hundred and two 15-year-old adolescents from two ongoing birth cohorts (GINIplus15 and LISAplus15) were examined to determine non-cavitated carious lesions (NCCL) and the DMF index. Furthermore, DHL was scored on all permanent teeth/surfaces according to the molar-incisor hypomineralisation criteria of the European Academy of Paediatric Dentistry (MIH/EAPD). Adolescents with DHL were categorised into those with a minimum of one DHL in the permanent dentition (DHL ≥ 1), with DHL on at least one first permanent molar (MIH/EAPD) and with DHL on at least one first permanent molar and permanent incisor (MIH/Severe). The study was conducted in the metropolitan area of Munich. The proportion of children without caries amounted to 63.7% (DMF > 0) and 26.0% (D 1-4 MF > 0); the caries experience was mean = 4.0(SD = 5.2) NCCL/T and 0.9(1.7) DMF/T. Existence of DHL ≥ 1, MIH/EAPD and MIH/Severe was detected in 40.2, 17.2 and 9.8% of all adolescents, respectively. The corresponding DMF/T values were: no DHL 0.9(1.7); DHL ≥ 1 1.0(1.7); MIH/EAPD 1.1(1.6); MIH/Severe 1.1(1.7). The group of adolescents with MIH/EAPD and MIH/Severe were found to have statistically higher caries rates in comparison to those with no DHL. Caries and DHL are prevalent and influenced the dental health of 15-year-old adolescents. A significant positive association existed between the presence of caries and DHL. Children with MIH/EAPD or MIH/Severe had a higher probability to develop carious lesions in the permanent dentition.

  6. Between demarcation and discretion: The medical-administrative boundary as a locus of safety in high-volume organisational routines.

    Science.gov (United States)

    Grant, Suzanne; Guthrie, Bruce

    2018-04-01

    Patient safety is an increasing concern for health systems internationally. The majority of administrative work in UK general practice takes place in the context of organisational routines such as repeat prescribing and test results handling, where high workloads and increased clinician dependency on administrative staff have been identified as an emerging safety issue. Despite this trend, most research to date has focused on the redistribution of the clinical workload between doctors, nurses and allied health professionals within individual care settings. Drawing on Strauss's negotiated order perspective, we examine ethnographically the achievement of safety across the medical-administrative boundary in key high-volume routines in UK general practice. We focus on two main issues. First, GPs engaged in strategies of demarcation by defining receptionist work as routine, unspecialised and dependent upon GP clinical knowledge and oversight as the safety net to deal with complexity and risk. Receptionists consented to this 'social closure' when describing their role, thus reinforcing the underlying inter-occupational relationship of medical domination. Second, in everyday practice, GPs and receptionists engaged in informal boundary-blurring to safely accommodate the complexity of everyday high-volume routine work. This comprised additional informal discretionary spaces for receptionist decision-making and action that went beyond the routine safety work formally assigned to them. New restratified intra-occupational hierarchies were also being created between receptionists based on the complexity of the safety work that they were authorised to do at practice level, with specialised roles constituting a new form of administrative 'professional project'. The article advances negotiated order theory by providing an in-depth examination of the ways in which medical-administrative boundary-making and boundary-blurring constitute distinct modes of safety in high

    1986-01-01

    Early diagnosis of the extent of bone and soft tissue damage is a very important step in treating a frostbite victim. The diagnostic use of Tc-99m-phosphates in assessing the viability of soft tissue and bone in frostbite was evaluated in the early post-thaw period. Four patients were treated with a combination of warm baths, rehydration, vasodilators, epidural block, fasciotomy, and debridement. Six scans were done to stage involvement. In three of the four cases, final involvement could be determined as early as the third day. When a specific level of soft tissue or bone uptake was determined, future scanning showed either improvement, or no change in three of the four patients. In our experience, Tc-99m-phosphate scans represent an improvement over other diagnostic tests for viability of tissues

  12. Temperature of the Gulf Stream

    Science.gov (United States)

    2002-01-01

    The Gulf Stream is one of the strong ocean currents that carries warm water from the sunny tropics to higher latitudes. The current stretches from the Gulf of Mexico up the East Coast of the United States, departs from North America south of the Chesapeake Bay, and heads across the Atlantic to the British Isles. The water within the Gulf Stream moves at the stately pace of 4 miles per hour. Even though the current cools as the water travels thousands of miles, it remains strong enough to moderate the Northern European climate. The image above was derived from the infrared measurements of the Moderate-resolution Imaging Spectroradiometer (MODIS) on a nearly cloud-free day over the east coast of the United States. The coldest waters are shown as purple, with blue, green, yellow, and red representing progressively warmer water. Temperatures range from about 7 to 22 degrees Celsius. The core of the Gulf Stream is very apparent as the warmest water, dark red. It departs from the coast at Cape Hatteras, North Carolina. The cool, shelf water from the north entrains the warmer outflows from the Chesapeake and Delaware Bays. The north wall of the Gulf Stream reveals very complex structure associated with frontal instabilities that lead to exchanges between the Gulf Stream and inshore waters. Several clockwise-rotating warm core eddies are evident north of the core of the Gulf Stream, which enhance the exchange of heat and water between the coastal and deep ocean. Cold core eddies, which rotate counter clockwise, are seen south of the Gulf Stream. The one closest to Cape Hatteras is entraining very warm Gulf Stream waters on its northwest circumference. Near the coast, shallower waters have warmed due to solar heating, while the deeper waters offshore are markedly cooler (dark blue). MODIS made this observation on May 8, 2000, at 11:45 a.m. EDT. For more information, see the MODIS-Ocean web page. The sea surface temperature image was created at the University of Miami using

    In this report, technologies for petroleum production and exploration enhancement in deepwater and mature fields are developed through basic and applied research by: (1) Designing new fluids to efficiently drill deepwater wells that can not be cost-effectively drilled with current technologies. The new fluids will be heavy liquid foams that have low-density at shallow dept to avoid formation breakdown and high density at drilling depth to control formation pressure. The goal of this project is to provide industry with formulations of new fluids for reducing casing programs and thus well construction cost in deepwater development. (2) Studying the effects of flue gas/CO{sub 2} huff n puff on incremental oil recovery in Louisiana oilfields bearing light oil. An artificial neural network (ANN) model will be developed and used to map recovery efficiencies for candidate reservoirs in Louisiana. (3) Arriving at a quantitative understanding for the three-dimensional controlled-source electromagnetic (CSEM) geophysical response of typical Gulf of Mexico hydrocarbon reservoirs. We will seek to make available tools for the qualitative, rapid interpretation of marine CSEM signatures, and tools for efficient, three-dimensional subsurface conductivity modeling.

  15. Fundamental challenges for autism research: the science-practice gap, demarcating autism and the unsuccessful search for the neurobiological basis of autism.

    Science.gov (United States)

    Verhoeff, Berend

    2015-08-01

    One of the central aims of autism research is to identify specific neurodevelopmental mechanisms that cause and explain the visible autistic signs and symptoms. In this short paper, I argue that the persistent search for autism-specific pathophysiologies has two fundamental difficulties. The first regards the growing gap between basic autism science and clinical practice. The second regards the difficulties with demarcating autism as a psychiatric condition. Instead of the unremitting search for the neurobiological basis of autism, I suggest that basic autism research should focus on experiences of impairment and distress, and on how these experiences relate to particular (autistic) behaviors in particular circumstances, regardless of whether we are dealing with an autism diagnosis or not.

    2009-04-01

    Full Text Available In the Limbe Subdivision of Cameroon, landslides and flooding are frequent threats. The worst recorded event occurred in June 2001, when floods and landslides took the lives of some 30 persons, left over 2000 people homeless, and destroyed property and social amenities including roads and telephone lines worth hundred of thousands of US Dollars. The objective of this project was to assist local administrative officers, other decision makers and planners to understand which areas to concentrate their efforts on in order to develop mitigation actions to protect the lives of the population in these zones that are affected by flooding and associated landslides. To meet this objective the project made extensive use of geospatial tools and existing digital spatial datasets. Series of field data collection exercises constituted an integral part of the project. The project focused on the Limbe subdivision in the south-western part of Cameroon. Areas with high (greater than 60% probability of sliding to occur, occupy 23% while areas with medium (greater than 40% and less than 60% probability of sliding to occur occupy 44% and areas with low (less than 40% probability of sliding occupy 33%. Settlements along the Atlantic coast all lie less than ~50m above sea level. These settlements (villages are susceptible to flooding. Again settlements in the town of Llimbe along the Djenguele river, i.e., Animal Farms, Cassava Farms, Lumpsum areas, Church Street, New Town and Down Beach, are more susceptible to inundation during raining periods and therefore have experienced persistent flooding over the years.

  6. Snow bands over the Gulf of Finland in wintertime

    Directory of Open Access Journals (Sweden)

    Jordi Mazon

    2015-01-01

    Full Text Available Large shore-parallel, quasi-stationary snow bands are occasionally observed over the Gulf of Finland during wintertime when the sea is not frozen. On the basis of Weather Research and Forecasting mesoscale model experiments and radar observations of snow bands formed in January 2006 and February 2012, we show that their dynamics share common characteristics: (1 the sea gulf that produces the known lake effect, (2 cold easterly large-scale flow along the gulf and (3 a cold local flow from the two near and opposite coastlines of Estonia and Finland in the form of two land-breeze cells which collide offshore. The associated fronts, which have strong rising motions, are maintained by the convergence of the land-breeze cells. In addition to these factors, the concave shape of the coast in the eastern part of the Gulf of Finland promotes offshore convergence and the formation of several secondary bands of precipitation that are adjacent to the eastern part of the main band. When the easterlies turn to southerlies, horizontal convective rolls appear over the sea. The Estonian land breeze is enhanced while the cold air remains stagnant inland over the Finnish coast, acting as an orographic barrier lifting the marine air mass upwards. Consequently, a line of convective precipitation composed of several cells is formed along the Finnish coast. In both events, the simulations also show two low-level jets generated by the combined effects of the land-breeze cells and baroclinicity over the coast of Finland and Estonia.

  7. Coral reefs in Saudi Arabia: 3.5 years after the Gulf War oil spill

    Science.gov (United States)

    Vogt, I. P.

    1995-11-01

    As a consequence of the 1991 Gulf War, 6-8 million barrels of oil were released into the marine environment and a total of 1.12 billion barrels were burned in the Kuwaiti oil fields. In order to detect delayed effects of the Gulf War pollution, six permanent transect lines were placed on Saudi Arabian offshore and inshore reefs. A comparison of three sets of video recordings taken between 1992 and 1994 indicated a significant increase in live coral cover. Therefore, it has been concluded that corals in Saudi Arabia survived the largest oil spill on record remarkably unscathed, with no visible signs of immediate or late effects up to 3.5 years after the Gulf War.

    2012-08-01

    This paper deals with a systematic hydrogeological, geophysical, and hydrochemical investigations carried out in SIPCOT area in Southern India to demarcate groundwater pollution and saline intrusion through Uppanar River, which flows parallel to sea coast with high salinity (average TDS 28, 870 mg/l) due to back waters as well as discharge of industrial and domestic effluents. Hydrogeological and geophysical investigations comprising topographic survey, self-potential, multi-electrode resistivity imaging, and water quality monitoring were found the extent of saline water intrusion in the south and pockets of subsurface pollution in the north of the study area. Since the area is beset with highly permeable unconfined quaternary alluvium forming potential aquifer at shallow depth, long-term excessive pumping and influence of the River have led to lowering of the water table and degradation of water quality through increased salinity there by generating reversal of hydraulic gradient in the south. The improper management of industrial wastes and left over chemicals by closed industries has led surface and subsurface pollution in the north of the study area.

    This document describes the contents of a digital data base that may be used to identify coastlines along the US Gulf Coast at risk to sea-level rise. The data base integrates point, line, and polygon data for the US Gulf Coast into 0.25{degree} latitude by 0.25{degree} longitude grid cells and into 1:2,000,000 digitized line segments that can be used by raster or vector geographic information systems (GIS) as well as by non-GIS data base systems. Each coastal grid cell and line segment contains data on elevation, geology, geomorphology, sea-level trends, shoreline displacement (erosion/accretion), tidal ranges, and wave heights. To allow for the identification of coastlines at risk from sea-level rise, 7 of the 22 original data variables in this data base were classified by vulnerability and used to create 7 relative risk variables. These relative risk variables range in value from 1 to 5 and may be used to calculate a coastal vulnerability index for each grid cell and/or line segment. The data for these 29 variables (i.e., the 22 original variables and 7 risk variables) have been placed into the following data formats: (1) Gridded polygon data for the 22 original data variables. Data include elevation, geology, geomorphology, sea-level trends, shoreline displacement (erosion/accretion), tidal ranges, and wave heights. (2) Gridded polygon data for the seven classified risk variables. The risk variables are classified versions of: mean coastal elevation, geology, geomorphology, local subsidence trend, mean shoreline displacement, maximum tidal range, and maximum significant wave height. (3) 1:2,000,000 line segment data containing the 29 data variables (the 22 original data variables and the seven classified risk variables). (4) Supplemental point data for the stations used in calculating the sea-level trend and tidal range data sets. (5) Supplemental line segment data containing a 1:2,000,000 digitized coastline of the US Gulf Coast as defined by this document.

    Objectives To determine how many veterans in a random sample of British veterans who served in the Gulf war believe they have “Gulf war syndrome,” to examine factors associated with the presence of this belief, and to compare the health status of those who believe they have Gulf war syndrome with those who do not. Design Questionnaire study asking British Gulf war veterans whether they believe they have Gulf war syndrome and about symptoms, fatigue, psychological distress, post-traumatic stress, physical functioning, and their perception of health. Participants 2961 respondents to questionnaires sent out to a random sample of 4250 Gulf war veterans (69.7%). Main outcome measure The proportion of veterans who believe they have Gulf war syndrome. Results Overall, 17.3% (95% confidence interval 15.9 to 18.7) of the respondents believed they had Gulf war syndrome. The belief was associated with the veteran having poor health, not serving in the army when responding to the questionnaire, and having received a high number of vaccinations before deployment to the Gulf. The strongest association was knowing another person who also thought they had Gulf war syndrome. Conclusions Substantial numbers of British Gulf war veterans believe they have Gulf war syndrome, which is associated with psychological distress, a high number of symptoms, and some reduction in activity levels. A combination of biological, psychological, and sociological factors are associated with the belief, and these factors should be addressed in clinical practice. What is already known on this topicThe term Gulf war syndrome has been used to describe illnesses and symptoms experienced by veterans of the 1991 Gulf warConcerns exist over the validity of Gulf war syndrome as a unique entityWhat this study adds17% of Gulf war veterans believe they have Gulf war syndromeHolding the belief is associated with worse health outcomesKnowing someone else who believes they have Gulf war syndrome and receiving

  17. Gulf war depleted uranium risks.

    Science.gov (United States)

    Marshall, Albert C

    2008-01-01

    US and British forces used depleted uranium (DU) in armor-piercing rounds to disable enemy tanks during the Gulf and Balkan Wars. Uranium particulate is generated by DU shell impact and particulate entrained in air may be inhaled or ingested by troops and nearby civilian populations. As uranium is slightly radioactive and chemically toxic, a number of critics have asserted that DU exposure has resulted in a variety of adverse health effects for exposed veterans and nearby civilian populations. The study described in this paper used mathematical modeling to estimate health risks from exposure to DU during the 1991 Gulf War for both US troops and nearby Iraqi civilians. The analysis found that the risks of DU-induced leukemia or birth defects are far too small to result in an observable increase in these health effects among exposed veterans or Iraqi civilians. The analysis indicated that only a few ( approximately 5) US veterans in vehicles accidentally targeted by US tanks received significant exposure levels, resulting in about a 1.4% lifetime risk of DU radiation-induced fatal cancer (compared with about a 24% risk of a fatal cancer from all other causes). These veterans may have also experienced temporary kidney damage. Iraqi children playing for 500 h in DU-destroyed vehicles are predicted to incur a cancer risk of about 0.4%. In vitro and animal tests suggest the possibility of chemically induced health effects from DU internalization, such as immune system impairment. Further study is needed to determine the applicability of these findings for Gulf War exposure to DU. Veterans and civilians who did not occupy DU-contaminated vehicles are unlikely to have internalized quantities of DU significantly in excess of normal internalization of natural uranium from the environment.

  3. Alaska, Gulf spills share similarities

    International Nuclear Information System (INIS)

    Usher, D.

    1991-01-01

    The accidental Exxon Valdez oil spill in Alaska and the deliberate dumping of crude oil into the Persian Gulf as a tactic of war contain both glaring differences and surprising similarities. Public reaction and public response was much greater to the Exxon Valdez spill in pristine Prince William Sound than to the war-related tragedy in the Persian Gulf. More than 12,000 workers helped in the Alaskan cleanup; only 350 have been involved in Kuwait. But in both instances, environmental damages appear to be less than anticipated. Natures highly effective self-cleansing action is primarily responsible for minimizing the damages. One positive action growing out of the two incidents is increased international cooperation and participation in oil-spill clean-up efforts. In 1990, in the aftermath of the Exxon Valdez spill, 94 nations signed an international accord on cooperation in future spills. The spills can be historic environmental landmarks leading to creation of more sophisticated response systems worldwide

    After three years of evaluating prospects and negotiating with government and industry representatives, Gulf Canada established its first joint venture in the Russian Federation with Komineft, a production association from the Komi autonomous republic. Komineft has a 50% share of the venture, and the rest is shared equally between Gulf and British Gas. The operating area is at the Vozey and Upper Vozey fields in the Timan-Pechora Basin, some 1,500 km northeast of Moscow just inside the Arctic Circle. An attractive feature of the Upper Vozey project is low development costs of ca $2/bbl. In the Vozey field, the venture will set up an enhanced oil recovery demonstration project to test techniques perfected in Alberta. About 60 Canadians are involved on the project, and headquarters are in Usinsk, ca 100 km south of the oil fields. In the first half of 1992, oil production in the first phase of the venture averaged around 10,000 bbl/d and continues to increase

  6. Thermohaline circulation in the Gulf of California

    Science.gov (United States)

    Bray, N. A.

    1988-05-01

    The Gulf of California, a narrow, semienclosed sea, is the only evaporative basin of the Pacific Ocean. As a result of evaporative forcing, salinities in the gulf are 1 to 2 ‰ higher than in the adjacent Pacific at the same latitude. This paper examines the thermohaline structure of the gulf and the means by which thermohaline exchange between the Pacific and the gulf occurs, over time scales of months to years. In addition to evaporative forcing, air-sea heat fluxes and momentum fluxes are important to thermohaline circulation in the gulf. From observations presented here, it appears that the gulf gains heat from the atmosphere on an annual average, unlike the Mediterranean and Red seas, which have comparable evaporative forcing. As a result, outflow from the gulf tends to be less dense than inflow from the Pacific. Winds over the gulf change direction with season, blowing northward in summer and southward in winter. This same seasonal pattern appears in near-surface transports averaged across the gulf. The thermohaline circulation, then, consists of outflow mostly between about 50 m and 250 m, inflow mostly between 250 m and 500 m, and a surface layer in which the direction of transport changes with seasonal changes in the large-scale winds. Using hydrographic observations from a section across the central gulf, total transport in or out of the northern gulf is estimated to be 0.9 Sv, heat gain from the atmosphere is estimated to be 20 to 50 W m-2, and evaporation is estimated to be 0.95 m yr-1. These estimates are annual averages, based on cruises from several years. Seasonal variations in thermohaline structure in the gulf are also examined and found to dominate the variance in temperature and density in the top 500 m of the water column. Salinity has little seasonal variability but does exhibit more horizontal variablility than temperature or density. Major year-to-year variations in thermohaline structure may be attributable to El Niño-Southern Oscillation

    1999-01-01

    Oil projects in the Gulf of Mexico have suffered from the crash in oil prices in the mid-1980s, however as these projects tend to be long-term and therefore less sensitive to current oil prices, many are continuing to be funded. It is now believed by deepwater exploration operators that the Gulf of Mexico may be one of the world's most promising sources of new reserves. This article analyses the likely future exploration of deepwater reserves by major companies such as Shell, noted for its capital intensive and technologically innovative activity in the Gulf, as well as the newer, smaller independent operators.

  1. Optical band gap demarcation around 2.15 eV depending on preferred orientation growth in red HgI{sub 2} films

    Energy Technology Data Exchange (ETDEWEB)

    2017-04-01

    Thermally evaporated stoichiometric films of red HgI{sub 2} show preferred orientation growth with either (102) or (002) orientation. The as grown films shows a change from one preferred orientation to another depending on their thickness, open-air heat-treatment and in-situ heat treatment of films. The in-situ heat-treatment of thermally evaporated stoichiometric films of red HgI{sub 2} with preferred growth of (102) orientation shows a gradual linear decrease in film thickness with in-situ heat-treatment temperature. On in-situ heat-treatment above 80 °C, it is found that HgI{sub 2} films become thinner than 900 nm, which are otherwise difficult to grow due to high vapor pressure of HgI{sub 2}. For these films the preferred orientation also changed from (102) to (002). The optical band gap (E{sub g}) also found to increase linearly with in-situ heat-treatment temperature. It is interesting to note that in-situ heat-treated films having (002) orientation had higher values of optical band gap than (102) orientation films. On combining these results with those of as grown and open-air heat-treated red HgI{sub 2} films reported in the literature, it is evident that there exists an optical band gap demarcation around 2.15 eV for red HgI{sub 2} thin films depending on their preferred orientation growth. Films with (102) orientation are found to have optical band gap less than 2.15 eV and those with (002) orientation are found to have optical band gap more than 2.15 eV. This is irrespective of the physical mean of obtaining the preferred orientation. The preferred orientation can be achieved by either physical means such as growing films with higher thickness, heat-treating them for short duration in open air or heat-treating them in-situ.

    Craig, M.J.K.; Hyde, S.T.

    1997-01-01

    Economic evaluations and recent experience show that the deepwater Gulf of Mexico (GOM) is much more profitable than previously thought. Four factors contributing to the changed viewpoint are: First, deepwater reservoirs have proved to have excellent productive capacity, distribution, and continuity when compared to correlative-age shelf deltaic sands. Second, improved technologies and lower perceived risks have lowered the cost of floating production systems (FPSs). Third, projects now get on-line quicker. Fourth, a collection of other important factors are: Reduced geologic risk and associated high success rates for deepwater GOM wells due primarily to improved seismic imaging and processing tools (3D, AVO, etc.); absence of any political risk in the deepwater GOM (common overseas, and very significant in some international areas); and positive impact of deepwater federal royalty relief. This article uses hypothetical reserve distributions and price forecasts to illustrate indicative economics of deepwater prospects. Economics of Shell Oil Co.'s three deepwater projects are also discussed

    One of the spin-offs from the Gulf War will be a change in the old order within OPEC. With Iraq and Kuwait production stopped because of the war, output from OPEC countries is around 23.5 million barrels per day compared with about 20 million last August before the Iraqi invasion of Kuwait. It is reported that there are some 225 to 235 million barrels of oil in inventory, worldwide, above normal levels. As seen in the accompanying graph, oil prices have drifted back to about the same level as in March 1990 from the wartime high of nearly $40/bbl. Before the invasion, Saudi Arabia's quota was 5.4 million bbls per day. Since then, Saudi has pumped at 7.7 to 7.9 bbls per day with plans to reactivate shut-in wells which will bring production capability to 10 million bbls per day. Other OPEC countries are at maximum capacity and some, Venezuela, for example, are also in the process of expanding production. This article discusses the effect of the war on the future oil supply, other countries' response to Iraq oil production, and prediction of possible oil price response

    1991-01-01

    The wealth of indigenous oil resources has largely determined the economic and energy use patterns in the member countries of the Gulf Cooperation Council (GCC). Sizable profits accrued from the inflation of world oil prices spurred tremendous economic growth across the Gulf during the 1970s. The GCC nations channeled this oil wealth into the rapid development of infrastructure and the creation of super-welfare states. Today, these highly affluent societies enjoy benefits ranging from free medical care, schooling and housing to subsidized electricity and gasoline supplies. The combination of great personal prosperity, abundant petroleum resources and highly subsidized energy prices has led to excessive energy use in the Gulf nations. These countries consume among the highest amounts of energy per capita in the world. Correspondingly, these nations generate among the highest levels of energy-related carbon per capita

  19. Gulf of Mexico deep-water

    Ott, G.L.

    1998-01-01

    The deepwater Gulf of Mexico, an emerging basin with 20 BBOE resource potential, was discussed. Technologies are advancing and development options are increasing within the Gulf of Mexico deepwater environment. Deepwater offers significant rate potentials leading to strong cash flows. The projected steep rate of resources captured in the next five years show that there is a short window of opportunity to establish a business position. The major production variables are development costs and cycle time. There is a definite market for Gulf of Mexico products because U.S. energy demand is expected to outstrip U.S. supply. Present infrastructure is capable of moving large volumes of gas into major U.S. markets, but with the large number of projects currently underway, especially in the United States, supply could exceed capacity. 1 tab., 16 figs

  20. The deepwater Gulf of Mexico : promises delivered?

    1999-01-01

    A summary review of deepwater Gulf of Mexico (GOM) oil production was presented for the years 1989 to 1998. Trends and prospects in deepwater GOM production and leasing were assessed. Promises and forecasts made in the early 1990s were compared with what actually happened since then. Forecasts in the early 1990s promised deeper, faster and cheaper developments in the deepwater Gulf. Results of the comparison showed that the prognosticators were correct on all three counts. Regarding the future of the Gulf, one can be justified in being optimistic in so far as more experience, robust economics, more and cheaper rigs can be taken as reliable indicators of optimism. In contrast, there are certain negatives to consider, such as low commodity prices, budget constraints, lease expirations, technical challenges and increased competition. . 12 figs

    A review of operations in 1998 and financial information from Gulf Canada Resources Limited is provided to keep shareholders abreast of company performance. Gulf Canada Resources Limited explores for, develops, produces and markets conventional and synthetic crude oil, natural gas and natural gas liquids. In 1998, the company's main operating centres were in western Canada (where it owns a nine per cent interest in the Syncrude Joint Venture), Indonesia, the North Sea and Australia. The report summarizes the company's energy resource activities, presents a detailed review of operations, and provides consolidated financial statements, and common share information. Although Gulf Canada Resources sold $ 1.2 billion worth of non-producing assets during the year, year end proved reserves of 838 million barrels of oil equivalent were less than ten per cent lower than a year earlier, reflecting reserve additions of 100 million barrels of oil equivalent. tabs., figs

    The Gulf Coast Clean Energy Application Center was initiated to significantly improve market and regulatory conditions for the implementation of combined heat and power technologies. The GC CEAC was responsible for the development of CHP in Texas, Louisiana and Oklahoma. Through this program we employed a variety of outreach and education techniques, developed and deployed assessment tools and conducted market assessments. These efforts resulted in the growth of the combined heat and power market in the Gulf Coast region with a realization of more efficient energy generation, reduced emissions and a more resilient infrastructure. Specific t research, we did not formally investigate any techniques with any formal research design or methodology.

    This set of images from the Multi-angle Imaging SpectroRadiometer highlights coastal areas of four states along the Gulf of Mexico: Louisiana, Mississippi, Alabama and part of the Florida panhandle. The images were acquired on October 15, 2001 (Terra orbit 9718)and represent an area of 345 kilometers x 315 kilometers.The two smaller images on the right are (top) a natural color view comprised of red, green, and blue band data from MISR's nadir(vertical-viewing) camera, and (bottom) a false-color view comprised of near-infrared, red, and blue band data from the same camera. The predominantly red color of the false-color image is due to the presence of vegetation, which is bright at near-infrared wavelengths. Cities appear as grey patches, with New Orleans visible at the southern edge of Lake Pontchartrain, along the left-hand side of the images. The Lake Pontchartrain Bridge runs approximately north-south across the middle of the lake. The distinctive shape of the Mississippi River Delta can be seen to the southeast of New Orleans. Other coastal cities are visible east of the Mississippi, including Biloxi, Mobile and Pensacola.The large image is similar to the true-color nadir view, except that red band data from the 60-degree backward-looking camera has been substituted into the red channel; the blue and green data from the nadir camera have been preserved. In this visualization, green hues appear somewhat subdued, and a number of areas with a reddish color are present, particularly near the mouths of the Mississippi, Pascagoula, Mobile-Tensaw, and Escambia Rivers. Here, the red color is highlighting differences in surface texture. This combination of angular and spectral information differentiates areas with aquatic vegetation associated with poorly drained bottom lands, marshes, and/or estuaries from the surrounding surface vegetation. These wetland regions are not as well differentiated in the conventional nadir views.Variations in ocean color are apparent in

  9. Mercury biogeochemistry in the Idrija River, Slovenia, from above the mine into the Gulf of Trieste

    The Idrija Mine is the second largest Hg mine in the world which operated for 500 years. Mercury (Hg)-laden tailings still line the banks, and the system is a threat to the Idrija River and water bodies downstream including the Soca/Isonzo River and the Gulf of Trieste in the northern Adriatic Sea. A multidisciplinary study was conducted in June 1998 on water samples collected throughout the Idrija and Soca River systems and waters and sediments in the Gulf. Total Hg in the Idrija River increased >20-fold downstream of the mine from 60 ng liter-1 with methyl mercury (MeHg) accounting for ~0.5%. Concentrations increased again downstream and into the estuary with MeHg accounting for nearly 1.5% of the total. While bacteria upstream of the mine did not contain mercury detoxification genes (mer), such genes were detected in bacteria collected downstream. Benthic macroinvertebrate diversity decreased downstream of the mine. Gulf waters near the river mouth contained up to 65 ng liter-1 total Hg with ~0.05 ng liter-1 MeHg. Gulf sediments near the river mouth contained 40 ??g g-1 total Hg with MeHg concentrations of about 3 ng g-1. Hg in sediment pore waters varied between 1 and 8 ng liter-1, with MeHg accounting for up to 85%. Hg methylation and MeHg demethylation were active in Gulf sediments with highest activities near the surface. MeHg was degraded by an oxidative pathway with >97% C released from MeHg as CO2. Hg methylation depth profiles resembled profiles of dissolved MeHg. Hg-laden waters still strongly impact the riverine, estuarine, and marine systems. Macroinvertebrates and bacteria in the Idrija River responded to Hg stress, and high Hg levels persist into the Gulf. Increases in total Hg and MeHg in the estuary demonstrate the remobilization of Hg, presumably as HgS dissolution and recycling. Gulf sediments actively produce MeHg, which enters bottom waters and presumably the marine food chain. (C) 2000 Academic Press.

  10. Influence of Subtropical Jetstream on Arabian Gulf Precipitation

    The Arabian Gulf and surrounding regions are predominantly arid. However, this region hosts a large population due to the intense economic activity that is centered on the exploration of natural resources in and around the Arabian Gulf. Thus, few precipitation events that occur during boreal winter are important for society and ecology of this region. The mechanisms of winter precipitation over the Gulf are not well understood, partly due to a lack of long term meteorological observation. Here we explore the dynamics of Arabian Gulf winter precipitation events using available observations and a high resolution atmospheric model simulation. Our analyses show that the northern Gulf receives about six times more precipitation than the southern Gulf. Often, the southern Gulf precipitation forms as a result of downstream development of northern Gulf disturbance. The southward movement of northern Gulf disturbances is influenced by the location of subtropical jet. The probability of a northern Gulf precipitating weather system to move south is higher when the subtropical jet is located equatorward of 30°N. The equatorward position of jet favors the penetration of mid-latitude weather systems over the Arabian Peninsula, which in turn pushes the Arabian anticyclone eastward and triggers moisture transport from the Arabian Sea that is essential for southern Gulf precipitation events.

    Full Text Available Taxonomic composition of fish larvae was analysed from 464 plankton samples obtained during 10 oceanographic surveys in the Gulf of California between 1984 and 1988. We identified 283 taxa: 173 species, 57 genera, and 53 families. Tropical and subtropical species predominated except during the winter, when temperate-subarctic species were dominant. The most abundant species were the mesopelagic Benthosema panamense, Triphoturus mexicanus and Vinciguerria lucetia, but the coastal pelagic species Engraulis mordax, Opisthonema spp., Sardinops caeruleus and Scomber japonicus were also prominent. The taxonomic composition of the ichthyoplankton shows the seasonality of the Gulf as well as environmental changes that occurred between the 1984-1987 warm period and the 1956-1957 cool period previously reported. The presence of E. mordax larvae as one of the most abundant species in the Gulf provides evidence of the reproduction of this species two years before the development of the northern anchovy fishery and the decline of the sardine fishery in the Gulf of California.

  3. Energy partnership: China and the Gulf states

    2005-01-01

    One of the most significant developments in the global energy market in the last several years has been China's skyrocketing demand for energy. In 1993, China became a net oil importer for the first time in its history and in 2003 replaced Japan as the world's second-largest oil importer (after the United States). The country needs more energy to maintain its spectacular economic performance. This study examines China's attempts to satisfy its growing needs for oil and natural gas by increasing imports from Russia and Central Asia/Caspian Sea region. The analysis suggests that despite growing cooperation between the two sides, the Gulf region is likely to satisfy most of China's hydrocarbons needs. Energy partnership between China and the Gulf has already started and is likely to be consolidated over the next few decades. The study also argues that this growing partnership between China and the Gulf should not be seen as a threat to any third party. The global energy market is well-integrated. Energy policy should not be seen in zero-sum terms. A China-Gulf partnership will benefit both sides and contribute to the stability of global energy markets. (author)

Mothers were interviewed three times over a 6 week period. Interviews were analyzed using interpretive methods. This manuscript highlights one particular theme-a positive perspective mothers described as the "silver lining." This "silver lining" represents optimism despite the adversities associated with parenting a child with ASD. A deeper understanding of this side of mothering children with ASD may help health care providers improve rapport, communication, and result in more authentic family centered care.

    The Gulf Coast Ecosystem Restoration Task Force (GCERTF) was established by Executive Order 13554 as a result of recommendations from “America’s Gulf Coast: A Long-term Recovery Plan after the Deepwater Horizon Oil Spill” by Secretary of the Navy Ray Mabus (Mabus Report). The GCERTF consists of members from 11 Federal agencies and representatives from each State bordering the Gulf of Mexico. The GCERTF was charged to develop a holistic, long-term, science-based Regional Ecosystem Restoration Strategy for the Gulf of Mexico. Federal and State agencies staffed the GCERTF with experts in fields such as policy, budgeting, and science to help develop the Strategy. The Strategy was built on existing authorities and resources and represents enhanced collaboration and a recognition of the shared responsibility among Federal and State governments to restore the Gulf Coast ecosystem. In this time of severe fiscal constraints, Task Force member agencies and States are committed to establishing shared priorities and working together to achieve them.As part of this effort, three staffers, one National Oceanic and Atmospheric Administration (NOAA) scientist and two U.S. Geological Survey (USGS) scientists, created and led a Science Coordination Team (SCT) to guide scientific input into the development of the Gulf of Mexico Regional Ecosystem Restoration Strategy. The SCT leads from the GCERTF coordinated more than 70 scientists from the Federal and State Task Force member agencies to participate in development of a restoration-oriented science document focused on the entire Gulf of Mexico, from inland watersheds to the deep blue waters. The SCT leads and scientists were organized into six different working groups based on expanded goals from the Mabus Report: Coastal habitats are healthy and resilient.Living coastal and marine resources are healthy, diverse, and sustainable.Coastal communities are adaptive and resilient.Storm buffers are sustainable.Inland habitats and

  7. Patterns of Hits to the Nearshore from a Major Fairway in the Gulf of Finland

    2012-04-01

    The Baltic Sea hosts one of the heaviest ship traffic in the world. Although relatively small in size, still up to 15% of the world's cargo is transported along its numerous fairways. The largest threat to the environment is oil transportation that has increased more than by a factor of two in 2000-2008 and a 40% increase is expected by the year 2015. One of the major marine highways in the European waters enters the Baltic Sea through the Danish Straits, crosses the Baltic Proper and stretches through the Gulf of Finland to Saint Petersburg. An area that is highly vulnerable to ship pollution is the nearshore that usually has the largest ecological value. While the probability of coastal pollution for open ocean coasts can be reduced by shifting ship routes farther offshore, the problem for narrow bays, like the Gulf of Finland, is how to minimize the probability of hitting any of the coasts. To a certain extent, light can be shed to this problem by means of quantification of the offshore areas in terms of their ability to serve a danger to coastal environment if pollution would happen in these areas. A convenient way to address this problem is to use statistical analysis of a large number of Lagrangian trajectories of test particles representing the potential pollution and passively carried by surface currents. In this paper, we make and attempt to quantify the link between potential sources of pollution along an existing fairway and the sections of the coast reached by current-driven pollution. The problem is analysed by means of considering hits to the nearshore from a major fairway in the Gulf of Finland and by making sure whether certain parts of the coast are hit by pollution particles most frequently and whether or not these pollution particles stem from certain specific parts of the fairway. Trajectories are simulated in the Gulf of Finland by placing tracers among a line that follows one of the major fairways from the Baltic Proper to Saint Petersburg

    The Arabian Gulf region has one of the highest ocean temperatures, reaching above 35 degrees and ambient temperatures over 50 degrees in the summer. Two nuclear power plants (NPP) are being introduced in the region for the first time, one at Bushehr (1,000 MWe PWR plant from Russia), and a much larger one at Barakah (4Χ1,400 MWe PWR from Korea). Both plants take seawater from the Gulf for condenser cooling, having to modify the secondary/tertiary side cooling systems design by increasing the heat transfer surface area from the country of origin. This paper analyses the secondary side of a typical PWR plant operating under the Rankine cycle with a simplified thermal-hydraulic model. Parametric study of ocean cooling temperatures is conducted to estimate thermal efficiency variations and its associated design changes for the secondary side. Operational safety is reviewed to deliver rated power output with acceptable safety margins in line with technical specifications, mainly in the auxiliary systems together with the cooling water temperature. Impact on the Gulf seawater as the ultimate heat sink is considered negligible, affecting only the adjacent water near the NPP site, when compared to the solar radiation on the sea surface.

    As part of the National Uranium Resource Evaluation program Geodata International, Inc. of Dallas, Texas, conducted an airborne gamma ray and total magnetic field survey of Beeville/Bay City Quadrangle of the Texas Gulf Coast area. Volume 1 gives the description of the program and results, and volume 2 gives the flight line profile data and statistical analysis results. The Beeville/Bay City Map Sheet shows Tertiary and Quaternary-aged strata which are part of the coastal plain of the Gulf Coast Geosyncline. The Cenozoic sediments overlie Mesozoic, Paleozoic, and Precambrian rocks, and have a relatively gentle homoclinal dip toward the gulf. The Quaternary and Tertiary sediments of the map sheet overlie the western flank of the Houston-East Texas Embayment, the northeastern side of the Rio Grande Embayment, and the San Marcos Arch. Recent and Pleistocene sediments crop-out in the south and east, and are more extensive in the vicinity of the structural embayments. The Pliocene-aged Goliad Formation crops-out extensively to the northwest. Miocene and Eocene strata occur in the northwestern corner of the map sheet. The uranium deposits occur in the Tertiary strata, but are most intensely mined in the Eocene strata immediately to the west of the map sheet area

    The author reports on discussions with two US companies about plans for using shuttle tankers to transport oil from platforms in the Gulf of Mexico to US ports as an alternative to pipeline networks. This follows approval by the US Minerals Management Service for FPSOs in the Gulf. The companies are American Shuttle Tankers and Conoco-owned Seahorse Shuttling and Technology. Because the vessels will enter US ports and operate in US waters, they must conform with the US Jones Act: they must be US-built, US-flagged and manned by US crews. They must also be double-hulled. This increases cost and reduces market opportunities for the vessels outside the US. The article also considers the use of articulated tug barges as another option. (UK)

    The future gas supply potential from the offshore Gulf of Mexico region was discussed with particular emphasis on the issue of whether there is enough growth potential to satisfy the anticipated growth in power generation markets. In 1980, a forecasted decrease in gas supply proved to be wrong. In fact, supply actually increased and productivity in the Gulf of Mexico has been relatively stable since 1982. A significant growth has been forecasted for 1997 to 2010. This growth will coincide with a large growth in gas demand in the northeastern U.S. The fact that electric power generation is changing hands adds to the opportunities in the northeast. It was emphasized that Canadian supply must be present to compete. 1 tab., 16 figs

    Hurricane Andrew's long term effect on Gulf of Mexico oil and gas operations likely won't be known until next year. This paper reports that while damage assessments have moved beyond the emergency stage, many offshore service companies say reliable estimates of the extent of damage or cost of repairs still are unavailable. The time needed to complete restorations won't be known conclusively until more organized surveys are complete. Even then, many contractors say, gulf operators must decide how to handle damage at each location-whether to repair damaged structures or replace them by applying technology not available when many of the fields were developed.

    2018-03-01

    The Gulf region is one of the most water-stressed parts in the world. Water in the region is very scarce, shortage of supply and lacking of renewable water resources, while the demand for water is growing day by day. It is thus essential to implement modern approaches and technologies in addressing water-related issues. In this context, isotope hydrology will provide invaluable aid. Some of the most important areas of futuristic applications of isotope hydrology include evaluation of aquifer recharge, storage and their recovery system, understanding of dynamic changes due to long-term exploitation of the groundwater, development and management of shared groundwater aquifers, fresh groundwater discharge along the Arabian Gulf, identification and quantification of hydrocarbon contamination in groundwater; soil moisture and solute movement in unsaturated zone, paleoclimate reconstruction, etc. Literature survey suggests, in general, not many isotope studies on the above have been reported.

    As cost pressures mount, Grand Gulf nuclear station (GGNS) is relying increasingly on various prioritization approaches to implement, modify, eliminate, or defer regulatory requirements. Regulatory requirements can be prioritized through the use of three measures: (1) safety (or risk) significance; (2) cost; and (3) public policy (or political) significance. This paper summarizes GGNS' efforts to implement solutions to regulatory issues using these three prioritization schemes to preserve a balance between cost and safety benefit

  20. Gulf Arab women's transition to motherhood.

    2013-01-01

    This paper is a report of the findings of a study of Gulf Arab women's perspectives of the transition to motherhood. Transition to motherhood is a universal phenomenon in which every culture has its own expectations and varying supports for women moving through this transition. International studies have provided models or categories of maternal responses related to cultural aspects of transition to motherhood. However, no known research has focused on transition to motherhood among Gulf Arab women. In the initial cohort seventeen first time Gulf Arab mothers in the United Arab Emirates were interviewed during the following three times: before childbirth, two-four weeks after childbirth, and forty-days after childbirth. A second cohort of seventeen first time new mothers was interviewed after childbirth in Sultanate of Oman. Four patterns were identified as indicators of change as women transitioned into motherhood: 1) Women's personal transition: women changed from feeling of freedom to feeling of dependency to self-confidence. 2) Mother/baby relationships: women changed from fear, anxiety, and uncertainty to feelings of care and confidence. 3) Family influences: women experienced family support to being integrated and feeling respected by family. 4) Cultural/religious beliefs and practices: women felt they were initially observers of culture, to experiencing cultural/religious beliefs and practices. This was followed by accomplishment in childbearing and childrearing practices. As Gulf Arab new mothers made the transition to motherhood, four implications for international nursing practice emerged: 1) patient teaching to help relieve anxiety, fears, and uncertainty, 2) facilitation of mother/baby relationships, 3) family-centered care, and 4) the importance of cultural/religious beliefs and practices to new mothers.

  11. A gateway to the Gulf

    Crawford, A.P.

    1992-01-01

    One day in February 1991, a man strolling along a bucolic stretch of rural real estate in Alabama heard the call of what he later discovered to be a red-cockaded woodpecker. A rare event, this would ordinarily have been a pleasant surprise. When officials at the Federal Energy Regulatory Commission (FERC) in Washington, D.C., got word of the red's siting, they took notice. And when Dan Mitchell and Jamie Craddock at United Gas Pipe Line Co. in Houston found out, they just shook their heads --- again. The red-cockaded woodpecker is but one of the uniquely named, federally protected species native to South Alabama that Mitchell and Craddock had to constantly concern themselves with as they attempted to ensure the environmental and regulatory compliance of United's recently completed 28-mile Gateway gas pipeline near gas-rich Mobile Bay. Until May 1, when United put Gateway into service, it had taken more than six years to plan and construct the most environmentally correct route for the pipeline. This paper discusses the largest portion of Gateway's route which is piney forest or agricultural land with the wetlands area prevalent in the southern end of the route

    Full Text Available The study of Zn in the water column of Saronikos Gulf in Greece during a two year period between 2008 and 2010 added data to the available time series of metal data for this marine area since 1985. The Saronikos Gulf, is directly influenced by the Athens metropolitan area. The operation of the Wastewater Treatment Plant of Athens situated on the small island of Psitalia, in 1995, was considered to be the turning point in the efforts of de-pollution of the gulf. Major sources of pollution for the gulf include also the port of Piraeus, with intensive navigation and shipping activities and the significant industrial activity occurring along the coast of Attica. This study of dissolved and particulate Zn gave results consistent with previous studies of the area such as the prevalence of the dissolved form of Zn and the most affected areas being the smaller most enclosed Gulf of Elefsina and Psitalia Island near the wastewater outfall. However, the concentrations of Zn were below toxic levels for marine aquatic organisms. Furthermore, a clear decrease in the Eastern part of the gulf was exhibited as well as a more subtle decrease in the gulf of Elefsina. The levels of Zn in Saronikos Gulf were found comparable to those of other Greek coastal areas.

    After Operation Desert Storm which took place in Iraq from August 1990 to July 1991 involving a coalition of 35 countries and a 700,000 strong contingent of mainly American men, some associations of war veterans, the media and researchers described a new diagnostic entity: the Gulf War Syndrome (GWS). GWS seems to be a new disorder which associates a litany of functional symptoms integrating the musculoskeletal, digestive, tegumentary and neurosensory systems. The symptoms presented do not allow a syndrome already known to be considered and the aetiology of the clinical picture remains unexplained, an increasing cause for concern resulting from the extent of the phenomenon and its media coverage. It quickly appears that there is no consensus amongst the scientific community concerning a nosographic description of GWS: where can all these functional complaints arise from? Different aetiopathogenic hypotheses have been studied by the American administration who is attempting to incriminate exposure to multiple risks such as vaccines and their adjuvants, organophosphorous compounds, pyridostigmine (given to the troops for the preventive treatment of the former), impoverished uranium, and the toxic emanations from oil well fires. But despite extremely in-depth scientific investigations, 10 years after the end of the war, no objective marker of physical suffering has been retained to account for the disorders presented. It would appear that the former soldiers are in even better objective health than the civil population whereas their subjective level of health remains low. Within this symptomatic population, some authors have begun to notice that the psychological disorders appear and persist associating: asthenia, fatigability, mood decline, sleep disorders, cognitive disorders and post-traumatic stress disorder (PTSD). Within the nosological framework, does GWS cause functional disorders or somatisation? Finally, 20 years after the end of the fighting, only PTSD has

    The Gulf of Mexico Research Initiative (GoMRI) was established at the time of one of the most significant ecological events in recent memory, the Deepwater Horizon oil spill. Defined by the discharge of over 150 million gallons of crude oil and the introduction of over 1.8 million gallons of chemical dispersants into the Gulf system, the impacts of the Deepwater Horizon disaster reached the Gulf Coast's wetlands and beaches and impacted the surface and deep ocean. The ecological story of the event reveals a strong linkage between the deep sea research community and research priorities in the Gulf of Mexico (coastal processes, human health, etc.). Deep Sea research efforts have revealed critical parts of the story, providing information on transport, fate, and effects of the Deepwater Horizon oil release and subsequent recovery of the Gulf of Mexico ecosystems.

    1992-01-01

    This paper reports that puny participation in the federal lease sale for the western Gulf of Mexico reflected a lack of open acreage on attractive prospects and the crisis sweeping the U.S. offshore oil and gas industry. Thirty-eight companies participating in the Minerals Management Service's Outer Continental Shelf Sale 141 offered 81 bids for 61 tracts in the western gulf planning area. That was the fewest bids offered in a western gulf sale since operators offered 52 bids for 41 tracts at Sale 105 in August 1986. The only Gulf of Mexico minerals sale to attract less bonus money was the MMS sulfur and salt sale in the central gulf in February 1988 in which $20.8 million was exposed

  12. Tectonoestratigraphic and Thermal Models of the Tiburon and Wagner Basins, northern Gulf of California Rift System

    2014-12-01

    The northern Gulf of California Rift System consist sofa series faults that accommodate both normal and strike-slip motion. The faults formed a series of half-greens filled with more than 7 km of siliciclastic suc­cessions. Here, we present tectonostratigraphic and heat flow models for the Tiburón basin, in the southern part of the system, and the Wag­ner basin in the north. The models are constrained by two-dimensional seis­mic lines and by two deep boreholes drilled by PEMEX­-PEP. Analysis of the seismic lines and models' results show that: (i) subsidence of the basins is controlled by high-angle normal faults and by flow of the lower crust, (ii) basins share a common history, and (iii) there are significant differences in the way brittle strain was partitioned in the basins, a feature frequently observed in rift basins. On one hand, the bounding faults of the Tiburón basin have a nested geometry and became active following a west-to-east sequence of activation. The Tiburon half-graben was formed by two pulses of fault activity. One took place during the protogulf extensional phase in the Miocene and the other during the opening of Gulf of California in the Pleistocene. On the other hand, the Wagner basin is the result of two fault generations. During the late-to middle Miocene, the west-dipping Cerro Prieto and San Felipe faults formed a domino array. Then, during the Pleistocene the Consag and Wagner faults dissected the hanging-wall of the Cerro Prieto fault forming the modern Wagner basin. Thermal modeling of the deep borehole temperatures suggests that the heat flow in these basins in the order of 110 mW/m2 which is in agreement with superficial heat flow measurements in the northern Gulf of California Rift System.

  13. Deepwater Gulf of Mexico: high prospects

    International Nuclear Information System (INIS)

    Kirkland, G.

    2000-01-01

    The present and future role of the deepwater Gulf of Mexico to meeting natural gas requirements of the United States are reviewed.The steady increase in U.S. demand, outpacing U.S.supply for over 10 years and the increasing reliance by the USA on Canadian exports is demonstrated in conjunction with the '30 Tcf Challenge'. Regarding the Gulf of Mexico specifically, it is estimated that to meet expectations, production there needs to grow to 22 Bcfpd by 2020, especially the deepwater pools which have a potential of 80 to 140 Tcf over the next 50 years. These pools already produce as much oil as the shelf region, but only 25 per cent as much gas. To produce the expected 7 to 12 Bcfpd oil production must reach 4 million barrel of oil per day, which involves cycle time, new technologies and cost challenges. Much of the new technology needed is related to cutting costs and while good progress is being made, it is argued that further gains could occur if international technology were applied in the Gulf. The rate of success in exploration has also improved, with over one billion barrels of deepwater discoveries per year over the last four years. Cycle times have also improved, although the impact of cycle time in the deeper water regions is cause for some concern. The overall assessment is that to get the gas, one has to get the oil first, meaning that deepwater success is more dependent on oil prices than on gas prices. Nevertheless, the need for developing and applying new technologies remains paramount, including the application of existing foreign technologies that have proven successful elsewhere. It is equally important to demonstrate a high level of environmental stewardship, and to continue focusing on cycle time, including access to prospective acreage, a well-trained workforce, and reasonable regulatory and permitting requirements

    The Gulf of Mexico annual summer hypoxia forecasts are based on average May total nitrogen loads from the Mississippi River basin for that year. The load estimate, recently released by USGS, is 7,316 metric tons per day. Based on that estimate, we predict the area of this summer’s hypoxic zone to be 18,900 square kilometers (95% credible interval, 13,400 to 24,200), the 7th largest reported and about the size of New Jersey. Our forecast hypoxic volume is 74.5 km3 (95% credible interval, 51.5 to 97.0), also the 7th largest on record.

    Sater, J.

    2014-01-01

    In many industrialized countries, the issue of migration has traditionally raised the question of whether migrant groups fully enjoy citizenship rights. Political debates about models of migration emphasize either the values of cultural diversity or the value of integration into 'host' societies,...... the lack of both integration and citizenship is a defining principle. Using these two perspectives, this article examines the relationship between citizenship rights and migration in the Gulf region, drawing on data from the UAE along with Bahrain, Kuwait, and Qatar.......In many industrialized countries, the issue of migration has traditionally raised the question of whether migrant groups fully enjoy citizenship rights. Political debates about models of migration emphasize either the values of cultural diversity or the value of integration into 'host' societies......, whereas fear and security concerns are often embedded in more populist debates.

  20. Site characterization plan: Gulf Coast salt domes

    International Nuclear Information System (INIS)

    1983-12-01

    The National Waste Terminal Storage (NWTS) program of the US Department of Energy (DOE) is responsible for developing technology and providing facilities for safe, environmentally acceptable, permanent disposal of high-level nuclear waste. The Office of Nuclear Waste Isolation has been intensively investigating Gulf Coast Salt Dome Basin salt domes and bedded salt in Texas and Utah since 1978. In the Gulf Coast, the application of screening criteria in the region phase led to selection of eight domes for further study in the location phase. Further screening in the area phase identified four domes for more intensive study in the location phase: Oakwood Dome, Texas; Vacherie Dome, Louisiana; and Richton Dome and Cypress Creek Dome, Mississippi. For each dome, this Site Characterization Plan identifies specific hydrologic, geologic, tectonic, geochemical, and environmental key issues that are related to the DOE/NWTS screening criteria or affect the feasibility of constructing an exploratory shaft. The Site Characterization Plan outlines studies need to: (1) resolve issues sufficiently to allow one or more salt domes to be selected and compared to bedded salt sites in order to determine a prime salt site for an exploratory shaft; (2) conduct issue-related studies to provide a higher level of confidence that the preferred salt dome site is viable for construction of an exploratory shaft; and (3) provide a vehicle for state input to issues.

  1. Gulf War Syndrome: a review of current knowledge and understanding.

    Science.gov (United States)

    Minshall, D

    2014-01-01

    The 1991 Persian Gulf War was a resounding military success for coalition forces, who liberated Kuwait following the Iraqi invasion. The medical legacy we have from the conflict is the poorly understood, yet remarkable, phenomenon of Gulf War Syndrome, which surfaced soon after. Epidemiological research has proven beyond doubt that Gulf War veterans report a wide variety of symptoms, in excess of appropriately matched control subjects, and experience worse general health. Numerous toxic environmental hazards have been suggested as causes of Gulf War Syndrome, yet exhaustive scientific study has failed to provide conclusive proof of any link. No novel or recognised disease has been found to account for the symptomatic burden of veterans, and the optimal treatment remains uncertain. This understanding can be added to from an anthropological perspective, where the narratives of those afflicted provide further insight. The nature of military life was changing at the time of the Gulf War, challenging the identity and beliefs of some veterans and causing socio-cultural distress. The symptomatic presentation of Gulf War Syndrome can be considered an articulation of this disharmony. Gulf War Syndrome can also be considered within the group of post-combat disorders such as shellshock, the like of which have occurred after major wars in the last century. With the current withdrawal from Afghanistan, the Defence Medical Services (DMS) should heed the lessons of history.

  2. Astronaut observations of the Persian (Arabian) Gulf during STS-45

    1992-01-01

    As a result of the 1991 Persian Gulf war, between mid-January and June 1991, the Persian Gulf was contaminated with an estimated 4 to 6 million barrels of crude oil, released directly into the Gulf from refinement facilities, transhipment terminals, and moored tankers along the coast of Kuwait, and precipitated from oil fire smoke plumes. To assess the environmental impact of the oil, an international team of marine scientists representing 14 nations was assembled under the auspices of the United Nations International Oceanic Commission and the Regional Organization for Protection of the Marine Environment to conduct detailed surveys of the Persian Gulf, the Strait of Hormuz, and the Gulf of Oman, including hydrographic, chemical, and biological measurements. To supplement the field surveys and to serve as an aid in data interpretation, astronauts aboard the Space Shuttle Atlantis photographed water features and coastal habitats in the Persian Gulf during mission STS-45 (24 March to 02 April 1992). The astronauts collected 111 hand-held, color photographs of the Gulf (72 70-mm photographs and 39 5-inch photographs) from an altitude of 296 km (160 n.mi.). The photographs reveal distributions in water turbidity associated with outflow from the Shatt-al-Arab and water circulation along the entire coast of Iran and the Strait of Hormuz, coastal wetlands and shallow-water habitats, and sticks appearing in the sunglint pattern, which appear to be oil.

  4. Long-pulse applications of pulse-forming lines for high-power linac application

    International Nuclear Information System (INIS)

    Hoeberling, R.F.; Tallerico, P.J.

    1981-01-01

    The ever present demands for high efficiency in the RF power stations for particle accelerators have caused increased interest in longer RF pulses (ten's of microseconds) for linacs such as the Pion Generator for Medical Irradiation (PIGMI) and Free Electron Laser (FEL). For either RF power station, a fundamental decision is whether to use a modulating anode/hard-tube driver or pulsed cathode/line-type pulser configuration. The choices in the extremes of low power for very long pulses or for very-high-power, short pulses are, respectively, a modulated anode/hard tube modulator and pulsed cathode/pulse forming line. However, the demarcation between these two extremes is not clearcut. The criteria (cost, flexibility performance, reliability, efficiency) that resulted in the RF station definition of these two specific systems will be described

    1972-01-01

    A SEEMING paradox has puzzled investigators of the crustal structure of the Gulf of Mexico since Ewing et al.1 calculated that a unit area of the rather thick crust in the gulf contains less mass than does a combination of the crust and enough of the upper mantle to make a comparable thickness in the Atlantic Ocean. They also noted that the free-air gravity of the gulf is essentially normal and fails by a large factor to be low enough to reflect the mass difference that they calculated. We propose a solution to this problem. ?? 1972 Nature Publishing Group.

    2016-01-01

    Data on the occurrence of whale sharks, Rhincodon typus, in the Arabian Gulf and Gulf of Oman were collected by dedicated boat surveys and via a public-sightings scheme during the period from 2011 to 2014. A total of 422 individual whale sharks were photo-identified from the Arabian Gulf and the northern Gulf of Oman during that period. The majority of sharks (81%, n = 341) were encountered at the Al Shaheen area of Qatar, 90 km off the coast, with the Musandam region of Oman a secondary area of interest. At Al Shaheen, there were significantly more male sharks (n = 171) than females (n = 78; X2 = 17.52, P 9 m individuals were visually assessed as pregnant. Connectivity among sharks sighted in Qatari, Omani and UAE waters was confirmed by individual spot pattern matches. A total of 13 identified sharks were re-sighted at locations other than that at which they were first sighted, including movements into and out of the Arabian Gulf through the Strait of Hormuz. Maximum likelihood techniques were used to model an estimated combined population for the Arabian Gulf and Gulf of Oman of 2837 sharks ± 1243.91 S.E. (95% C.I. 1720-6295). The Al Shaheen aggregation is thus the first site described as being dominated by mature males while the free-swimming pregnant females are the first reported from the Indian Ocean.

    Gulf Area Oil Companies Mutual Aid Organisation (GAOCMAO), has taken active steps in cooperation with its member companies, national and regional environmental organisation (ROPME) in an attempt to protect the Gulf from various sources of pollution. Specific attention was given to oil pollution response in terms of stockpiling of adequate equipment, training of personal and coordination through the application of pre-prepared contingency plans. All these activities tell us that a lot has been done to protect the Gulf environment from pollution. GAOCMAO, after many years of successful development looks to the future with confidence and renewed vigor. It is the intention of this organisation to enhance its member companies capabilities to respond to major incidents and to work closely with the national governmental, regional and international environmental organisations throughout the world, in fields appropriate to the Gulf oil industry.

  14. Future role of Gulf oil in world energy demand

    International Nuclear Information System (INIS)

    Eltony, M.N.

    1998-01-01

    The view that there will be a growing dependence on oil from the Gulf countries is shared by a great number of oil market analysts. This view is based on the fact that Gulf countries dominate the global oil reserves. Energy analyst argue that as the world demand for oil continues to grow driven largely by the growth in developing countries' consumption coupled with constrained non-OPEC supply, the end result will be that the call on Gulf oil will grow substantially. In summary, this paper has challenged the view of growing dependence on oil from the Gulf using available information in conjunction with reasonable and fairly plausible arguments. The aim was to point out to the GCC member counties the danger of relying on these views in shaping their economic policies and in setting their oil market strategies. They may run the ultimate risk of being left with huge oil reserves that no one wants. (orig.)

    A reconnaissance survey of the salt domes of Mississippi, Louisiana, and east Texas is being planned to identify study areas for potential sites for radioactive waste disposal. Preliminary screening specifications were derived for each of the geological evaluation criteria by application of the significant factors that will have an impact on the reconnaissance survey. The procedure for the derivation of each screening specification is discussed. The screening specifications are the official OWI values to be used for the first-cut acceptance for salt dome study areas along the Gulf Coast. The derivation of the screening specifications is illustrated by (1) a statement of the geological evaluation criterion, (2) a discussion of the pertinent factors affecting the criterion, and (3) the evaluation of the value of the specification

  17. Depleted uranium and the Gulf War syndrome

    International Nuclear Information System (INIS)

    1999-01-01

    Some military personnel involved in the 1991Gulf War have complained of continuing stress-like symptoms for which no obvious cause has been found. These symptoms have at times been attributed to the use of depleted uranium (DU) in shell casings which are believed to have caused toxic effects. Depleted uranium is natural uranium which is depleted in the rarer U-235 isotope. It is a heavy metal and in common with other heavy metals is chemically toxic. It is also slightly radioactive and could give rise to a radiological hazard if dispersed in finely divided form so that it was inhaled. In response to concerns, the possible effects of DU have been extensively studied along with other possible contributors to G ulf War sickness . This article looks at the results of some of the research that has been done on DU. (author)

    The Gulf War inflicted dramatic environmental damage upon the fragile desert and shore environments of Kuwait and northeastern Saudi Arabia. Coastal and marine environments experienced oil spills of more than 8 million barrels, which killed wildlife and damaged the fishing industry. In inland Kuwait, hundreds of oil lakes are scattered across the desert surface: these lakes emit noxious gases, drown insects and birds, and may seep to pollute groundwater. Exploding and burning oil wells released soot particles, oil droplets, and noxious chemicals into the atmosphere, spreading air pollution, acid rain, and respiratory problems. Military diggings, constructions, and vehicles have destroyed much of the desert pavement, resulting in increased dust storms and large, moving dunes

    The intentional and unintentional movement of plants and animals by humans has transformed ecosystems and landscapes globally. Assessing when and how a species was introduced are central to managing these transformed landscapes, particularly in island environments. In the Gulf of Alaska, there is considerable interest in the history of mammal introductions and rehabilitating Gulf of Alaska island environments by eradicating mammals classified as invasive species. The Arctic ground squirrel (Urocitellus parryii) is of concern because it affects vegetation and seabirds on Gulf of Alaska islands. This animal is assumed to have been introduced by historic settlers; however, ground squirrel remains in the prehistoric archaeological record of Chirikof Island, Alaska, challenge this timeline and suggest they colonized the islands long ago. We used 3 lines of evidence to address this problem: direct radiocarbon dating of archaeological squirrel remains; evidence of prehistoric human use of squirrels; and ancient DNA analysis of dated squirrel remains. Chirikof squirrels dated to at least 2000 years ago, and cut marks on squirrel bones suggested prehistoric use by people. Ancient squirrels also shared a mitochondrial haplotype with modern Chirikof squirrels. These results suggest that squirrels have been on Chirikof longer than previously assumed and that the current population of squirrels is closely related to the ancient population. Thus, it appears ground squirrels are not a recent, human-mediated introduction and may have colonized the island via a natural dispersal event or an ancient human translocation. © 2016 The Authors.

  2. Variations of Oceanic Crust in the Northeastern Gulf of Mexico From Integrated Geophysical Analysis

    Science.gov (United States)

    Liu, M.; Filina, I.

    2017-12-01

    Tectonic history of the Gulf of Mexico remains a subject of debate due to structural complexity of the area and lack of geological constraints. In this study, we focus our investigation on oceanic domain of the northeastern Gulf of Mexico to characterize the crustal distribution and structures. We use published satellite derived potential fields (gravity and magnetics), seismic refraction data (GUMBO3 and GUMBO4) and well logs to build the subsurface models that honor all available datasets. In the previous study, we have applied filters to potential fields grids and mapped the segments of an extinct mid-ocean ridge, ocean-continent boundary (OCB) and several transform faults in our study area. We also developed the 2D potential fields model for seismic profile GUMBO3 (Eddy et al., 2014). The objectives of this study are: 1) to develop a similar model for another seismic profile GUMBO 4 (Christeson, 2014) and derive subsurface properties (densities and magnetic susceptibilities), 2) to compare and contrast the two models, 3) to establish spatial relationship between the two crustal domains. Interpreted seismic velocities for the profiles GUMBO 3 and GUMBO 4 show significant differences, suggesting that these two profiles cross different segments of oceanic crust. The total crustal thickness along GUMBO 3 is much thicker (up to 10 km) than the one for GUMBO 4 (5.7 km). The upper crustal velocity along GUMBO 4 (6.0-6.7 km/s) is significantly higher than the one for GUMBO 3 ( 5.8 km/s). Based our 2D potential fields models along both of the GUMBO lines, we summarize physical properties (seismic velocities, densities and magnetic susceptibilities) for different crustal segments, which are proxies for lithologies. We use our filtered potential fields grids to establish the spatial relationship between these two segments of oceanic crust. The results of our integrated geophysical analysis will be used as additional constraints for the future tectonic reconstruction of

    Eighteen measurements in and near the gulfs of California and Aden indicate the geothermal flux is several times the world-wide mean of 1.2 x 10(-6) cal/cm(2) sec in both regions. Both gulfs closely coincide with the intersection of oceanic rises with continents and have likely been formed under tensional forces, which suggests an association with mantle convection currents.

    1995-01-01

    The rapid economic change experienced in the Arab Gulf countries in the past two decades has resulted in a dramatic decline in the number of infants breast fed and the duration of breast feeding. This survey describes the current status of breast feeding in the Arabian Gulf countries in terms of the duration of exclusive breast feeding; initiation, frequency, and duration of breast feeding; bottle feeding practices; breast feeding and fertility; reasons for cessation of breast feeding; and the relationship between breast feeding and gastroenteritis. After a brief discussion of weaning practices, the paper considers factors influencing the decision to breast feed, including mothers age, education, urban-rural residence, and employment status; the influence of house maids and health workers; and the sex of the child. The marketing of baby foods in the area is described, as are various programs to support breast feeding, such as maternity protection, educational activities, marketing activities, support of appropriate weaning practices, workshops and seminars, and research activities. It is concluded that these programs have had very little effect on the promotion of breast feeding in the region for the following reasons: 1) lack of coordination; 2) lack of health regulations covering formulas and baby foods; 3) the encouragement of bottle feeding in private hospitals; 4) insufficient knowledge of managing breast feeding among health personnel; 5) a shortage of studies relating to breast feeding; and 6) insufficient training of health personnel. The institution of a global promotional policy is recommended. Such a policy would include the development of strict regulations covering marketing of substitutes, training of health workers, mass media campaigns, school and university curricula changes, and convincing policy-makers that breast feeding is beneficial.

    This review examines the substantial changes that have taken place in marine habitats and resources of the Gulf over the past decade. The habitats are especially interesting because of the naturally high levels of temperature and salinity stress they experience, which is important in a changing world climate. However, the extent of all natural habitats is changing and their condition deteriorating because of the rapid development of the region and, in some cases from severe, episodic warming episodes. Major impacts come from numerous industrial, infrastructure-based, and residential and tourism development activities, which together combine, synergistically in some cases, to cause the observed deterioration in most benthic habitats. Substantial sea bottom dredging for material and its deposition in shallow water to extend land or to form a basis for huge developments, directly removes large areas of shallow, productive habitat, though in some cases the most important effect is the accompanying sedimentation or changes to water flows and conditions. The large scale of the activities compared to the relatively shallow and small size of the water body is a particularly important issue. Important from the perspective of controlling damaging effects is the limited cross-border collaboration and even intra-country collaboration among government agencies and large projects. Along with the accumulative nature of impacts that occur, even where each project receives environmental assessment or attention, each is treated more or less alone, rarely in combination. However, their combination in such a small, biologically interacting sea exacerbates the overall deterioration. Very few similar areas exist which face such a high concentration of disturbance, and the prognosis for the Gulf continuing to provide abundant natural resources is poor. Copyright 2009.

Among many, two complains are more frequent: inadequate definition of security and unstated assumptions in the security model. In our experience, one principal cause...... for such state of affairs is an apparent overlap of security and correctness, which may lead to many sloppy security definitions and security models. Although there is no inherent need to separate security and correctness requirements, practically, such separation is significant. It makes security analysis...... easier, and enables us to define security goals with a fine granularity. We present one such separation, by introducing the notion of binding sequence as a security primitive.

    2009-06-01

    As there seems to be a recurrent feeling of crisis in psychology, its present state is analyzed in this article. The author believes that in addition to the traditional manifestations that have dogged psychology since it emerged as an independent science some new features of the crisis have emerged. Three fundamental "ruptures" are identified: the "horizontal" rupture between various schools and trends, the "vertical" rupture between natural science and humanitarian psychology, and the "diagonal" rupture between academic research and applied practice of psychology. These manifestations of the crisis of psychology have recently been compounded by the crisis of its rationalistic foundations. This situation is described in terms of the cognitive systems in psychology which include meta-theories, paradigms, sociodigms and metadigms.

    Full Text Available Aerial photographic maps and landsat image interpretations suggest the major fault segments of the Three PagodaFault (TPF Zone and Sri Swat Fault (SSF Zone are oriented parallel or sub-parallel in the same NW-SE directions. The KwaeNoi River is running along the TPF in the south whereas the Kwae Yai River is running along the SSF in the north. Thesoutheastern continuation of both faults is obscured by thick Cenozoic sediments. Hence, surface lineaments cannot betraced with confidence. However, based on some interpretations of the airborne magnetic survey data, the trace of such faultsare designated to run through the western part of Bangkok and the northern end of the Gulf of Thailand. Paleo-earthquakesand the presence of hot springs along the fault zones indicate that they are tectonically active. The changes of both physicaland chemical properties of the water from Hin Dart Hot Spring and those of the surface water from a shallow well at Ban KhaoLao during the Great Sumatra–Andaman Earthquake on 26th of December 2004 clearly indicated that the southeastern continuation of the TPF is at least as far south as Pak Tho District, Ratburi. Our new evidence of the alignment of the high heatflow in the upper part of the Gulf of Thailand verified that the TPF also extend into the Gulf via Samut Songkhram Province.Studies of the seismic data from two survey lines along the Western part of the upper Gulf of Thailand acquired by BritoilPlc. in 1986, namely Line A which is approximately 60 km long, starting from Bang Khen passing through Bang Khae andending in Samut Songkhram and Line B is approximately 30 km long starting from Samut Sakon ending in Samut Song Khramsuggest that all the faults or fractures along these seismic profiles are covered by sediments of approximately 230 m thickwhich explain that the fault underneath these seismic lines is quite old and may not be active.

  15. Marine modification of terrestrial influences on Gulf hypoxia: Part II

    Directory of Open Access Journals (Sweden)

    2007-01-01

    Full Text Available This study examines potential marine modification of two classes of terrestrial influence on Gulf hypoxia: (1 the flow of nutrient-rich water from the Mississippi/Atchafalaya River Basin and (2 the massive physical, hydrological, chemical and biological change associated with the Atchafalaya’s partial capture of the Mississippi River. The latter involves repartitioning of a total flow of about 20 000 m3 sec−1, equal to that of 13 Nile Rivers, and a sediment load of 210 million metric tonnes yr−1,nearly 20 times that delivered by all of the rivers of the East Coast of the USA. Also involved is the loss of hundreds-to-thousands of years of stored nutrients and organic matter to the Gulf from enormous coastal wetland loss. This study found that the oceanography of the Gulf minimises the impact of both classes of terrestrial influence from the Mississippi River and its nearby estuaries on Gulf hypoxia. Oceanographic conditions give events associated with the Atchafalaya River a disproportionately large influence on Gulf hypoxia. A truly holistic environmental approach which includes the full effects of this highly dynamic coastal area is recommended to better understand and control Gulf hypoxia.

  16. Influence of the Gulf Stream on the troposphere.

    The Gulf Stream transports large amounts of heat from the tropics to middle and high latitudes, and thereby affects weather phenomena such as cyclogenesis and low cloud formation. But its climatic influence, on monthly and longer timescales, remains poorly understood. In particular, it is unclear how the warm current affects the free atmosphere above the marine atmospheric boundary layer. Here we consider the Gulf Stream's influence on the troposphere, using a combination of operational weather analyses, satellite observations and an atmospheric general circulation model. Our results reveal that the Gulf Stream affects the entire troposphere. In the marine boundary layer, atmospheric pressure adjustments to sharp sea surface temperature gradients lead to surface wind convergence, which anchors a narrow band of precipitation along the Gulf Stream. In this rain band, upward motion and cloud formation extend into the upper troposphere, as corroborated by the frequent occurrence of very low cloud-top temperatures. These mechanisms provide a pathway by which the Gulf Stream can affect the atmosphere locally, and possibly also in remote regions by forcing planetary waves. The identification of this pathway may have implications for our understanding of the processes involved in climate change, because the Gulf Stream is the upper limb of the Atlantic meridional overturning circulation, which has varied in strength in the past and is predicted to weaken in response to human-induced global warming in the future.

    The general characteristics of a planning model for the electrical generation system expansion with risk demarcation criteria, as well as the main results of a representative study case of the Mexican Electrical System is presented. The model is based on a methodology of multiannual optimization for the generation expansion plans determination. In this context, every expansion plan defines the technology type to be installed, as well as the installation year, unit size and its location within a regional electric network. For this purpose, the model considers an interregional representation of the system identifying the necessary reinforcements to the capacity of the interregional connections. It also incorporates a Demarcation of Risk module that considers the uncertainty of the future scenarios of fuels prices to generate a set of expansion plans, among which includes the following: a) For every future of the fuel prices: the plan that diminishes the present value of the total cost (investment plus production). b) The plan that diminishes the economic risk derived from the uncertainty in the future of the fuel prices. c) A subgroup of expansion plans that are located in the efficient borders of decision, under the context of three criteria of interest: the economic risk, the investment cost of and the total cost in the future considered of greater relevance.

    Marghany, Maged

    2016-10-01

    In this work, a genetic algorithm is exploited for automatic detection of oil spills of small and large size. The route is achieved using arrays of RADARSAT-2 SAR ScanSAR Narrow single beam data obtained in the Gulf of Mexico. The study shows that genetic algorithm has automatically segmented the dark spot patches related to small and large oil spill pixels. This conclusion is confirmed by the receiveroperating characteristic (ROC) curve and ground data which have been documented. The ROC curve indicates that the existence of oil slick footprints can be identified with the area under the curve between the ROC curve and the no-discrimination line of 90%, which is greater than that of other surrounding environmental features. The small oil spill sizes represented 30% of the discriminated oil spill pixels in ROC curve. In conclusion, the genetic algorithm can be used as a tool for the automatic detection of oil spills of either small or large size and the ScanSAR Narrow single beam mode serves as an excellent sensor for oil spill patterns detection and surveying in the Gulf of Mexico.

    This study describes catches of Anguilla rostrata glass eels and associated oceanographic conditions in the St Lawrence Estuary and Gulf. Ichthyoplankton survey data suggest that they enter the Gulf primarily in May, migrate at the surface at night, and disperse broadly once they have passed Cabot Strait. They arrive in estuaries beginning at about mid-June and through the month of July. Migration extends west up to Québec City, in the freshwater zone of the St Lawrence Estuary, 1000 km west of Cabot Strait. Anguilla rostrata glass eels travel between Cabot Strait and receiving estuaries at a straight-line ground speed of c. 10-15 km day(-1). Catches of fish per unit effort in estuaries in the St Lawrence system are much lower than those reported for the Atlantic coast of Canada. Low abundance of A. rostrata glass eels in the St Lawrence system may be due to cold surface temperatures during the migration period which decrease swimming capacity, long distances from the spawning ground to Cabot Strait and from Cabot Strait to the destination waters (especially the St Lawrence River), complex circulation patterns, and hypoxic conditions in bottom waters of the Laurentian Channel and the St Lawrence Estuary.

    2007-05-01

    Data from a number of high resolution 2D multichannel seismic (MCS) lines were used to investigate the structure and stratigraphy of the western Farallon basin in the southern Gulf of California. A Generator-Injector air gun provided a clean seismic source shooting each 12 s at a velocity of 6 kts. Each signal was recorded during 6- 8 s, at a sampling interval of 1 ms, by a 600 m long digital streamer with 48 channels and a spacing of 12.5 m. The MCS system was installed aboard CICESE's (Centro de Investigacion Cientifica y de Educacion Superior de Ensenada) 28 m research vessel Francisco de Ulloa. MCS data were conventionally processed, to obtain post- stack time-migrated seismic sections. The MCS seismic sections show a very detailed image of the sub-bottom structure up to 2-3 s two-way travel time (aprox. 2 km). We present detailed images of faulting based on the high resolution and quality of these data. Our results show distributed faulting with many active and inactive faults. Our study also constrains the depth to basement near the southern Baja California eastern coast. The acoustic basement appears as a continuous feature in the western part of the study area and can be correlated with some granite outcrops located in the southern Gulf of California islands. To the East, near the center of the Farallon basin, the acoustic basement changes, it is more discontinuous, and the seismic sections show a number of diffracted waves.

    Sediments collected from the North Coast of the Gulf of Mexico got carefully mixed, dried, and finally subjected to physical and chemical analysis. Metal concentration was determined by energy dispersive X-ray fluorescence (EDXRF). Sequential chemical analysis was performed by modified TESSIER technique. Results and statistical analysis (α = 0.05) show concentrations of most elements (excepting Mn, Ca, Ga, As and Pb) in the range of those of the earth crust's values, which set a sampling zone base line. Sequential extraction shows the potential risk of mobilization of metals sequestered in particulate phases by oxidation of anoxic sediments or intense organic matter degradation. (author)

  3. Continental breakup by oblique extension: the Gulf of California

    Science.gov (United States)

    van Wijk, J.; Axen, G. J.

    2017-12-01

    We address two aspects of oblique extension: 1) the evolution of pull-apart basins, and how/when they may evolve into seafloor spreading segments; and 2) the formation of microcontinents. The Gulf of California formed by oblique extension. Breakup resulted in oceanic crust generation in the southern and central parts, while in the northern Gulf/Salton Trough a thick layer of (meta-)sediments overlies thinned continental crust. We propose a simple mechanism to explain this N-S variation. We assume that oblique rifting of the proto-Gulf province resulted in pull-apart basins, and use numerical models to show that such pull-apart basins do not develop into seafloor spreading segments when their length-to-width ratios are small, as is the case in the northern Gulf. In the central and southern Gulf the length-to-width ratios were larger, promoting continent rupture. The mechanisms behind this fate of pull-apart basins will be discussed in the presentation. In the southern Gulf, potential field models show that the Tamayo Bank in the southern Gulf is likely a microcontinent, separated from the main continent by the Tamayo trough. The thickness of the ocean crust in the Tamayo trough is anomalously small, suggesting that initial seafloor spreading was magma-starved and unsuccessful, causing the location of rifting and seafloor spreading to jump. As a consequence a sliver of continent broke off, forming the microcontinent. We suggest that worldwide this may be a common process for microcontinent formation.

    1992-01-01

    This paper reports that interest in oil and gas leases in the Gulf of Mexico continued spiraling downward at the latest Minerals Management Service offshore sale. Companies participating in Outer Continental Shelf Sale 139 last week in New Orleans offered 196 bids for 151 blocks in the central Gulf of Mexico. MMS offered 5,213 blocks for lease. The number of tracts receiving bids was the fewest at a central gulf lease sale since 114 tracts garnered high bids totaling $146.4 million at Sale 104 in April 1986. Apparent high bids in Sale 139 totaled $56,195,552, and all bids offered totaled just $65,300,864. Both bidding totals were the lowest in a Gulf of Mexico lease sale since MMS began area-wide gulf leasing at Sale 72 in May 1983. Only 64 of 93 qualified companies participated in Sale 139. Fifty-five companies offered apparent winning bids. By comparison, 123 companies at central gulf lease Sale 131 in March 1991 offered 637 bids totaling $320.5 million for 464 tracts. Apparent high bids last spring totaled $259.9 million. At central gulf lease Sale 123 in March 1990, high bids totaled $427.4 million for 538 tracts. In that sale, BP Exploration Inc. led all bidders, exposing $78 million in 79 high bids, including 60 for deepwater tracts. Since then, interest in deepwater tracts has waned in part because of sagging oil and gas prices as U.S. operators sought bigger prospects outside the U.S. Ironically, Sale 139 was dominated by the U.S. subsidiary of an Italian holding company

    Building sector consumes a significant amount of energy worldwide (up to 40% of the total global energy); moreover, by the year 2030 the consumption is expected to increase by 50%. One of the reasons is that the performance of buildings and its components degrade over the years. In recent years, energy benchmarking for government office buildings, large scale public buildings and large commercial buildings is one of the key energy saving projects for promoting the development of building energy efficiency and sustainable energy savings in Gulf Cooperation Council (GCC) countries. Benchmarking would increase the purchase of energy efficient equipment, reducing energy bills, CO_2 emissions and conventional air pollution. This paper focuses on energy benchmarking for shopping centers in Gulf Coast Region. In addition, this paper will analyze a sample of shopping centers data in Gulf Coast Region (Dubai, Ajman, Sharjah, Oman and Bahrain). It aims to develop a benchmark for these shopping centers by highlighting the status of energy consumption performance. This research will support the sustainability movement in Gulf area through classifying the shopping centers into: Poor, Usual and Best Practices in terms of energy efficiency. According to the benchmarking analysis in this paper, the shopping centers best energy management practices in the Gulf Coast Region are the buildings that consume less than 810 kW h/m"2/yr, whereas the poor building practices are the centers that consume greater than 1439 kW h/m"2/yr. The conclusions of this work can be used as a reference for shopping centres benchmarking with similar climate. - Highlights: •The energy consumption data of shopping centers in Gulf Coast Region were gathered. •A benchmarking of energy consumption for the public areas for the shopping centers in the Gulf Coast Region was developed. •The shopping centers have the usual practice in the region between 810 kW h/m"2/yr and 1439 kW h/m"2/yr.

    Switching fuels from high-sulfur heavy fuel oils (HFO) to lower sulfur marine gas oils (MGO) on an oceangoing vessel (OGV) can substantially reduce both PM and SO(x) ship stack emissions, potentially resulting in significant human health and environmental benefits in Gulf of Mexico port communities. The International Maritime Organization (IMO) established an emission control area (ECA) within 200 nautical miles of the US. and Canadian coastlines and French territories off the coast of Canada with lower fuel sulfur standards effective beginning August 2012, where OGVs will need to switch from HFO to MGO. However some operators and other stakeholders, particularly in the Gulf of Mexico, may be unfamiliar with the benefits and requirements and ship operators may be concerned over potential implications for cost and operations. This first-ever US. Environmental Protection Agency (EPA)-sponsored fuel switching demonstration in the Gulf of Mexico was initiated to showcase the environmental and health benefits of as well as operational issues associated with, fuel switching through the following activities: (1) Fuel switching was conducted on typical container ships operating the Gulf of Mexico, as routine fuel switching has been demonstrated in California in recent years. Two vessels were employed in the demonstration: the Maersk Roubaix, which switched fuels entering Port of Houston, TX, and the Port of Progreso, Mexico, and the Hamburg Süd vessel Cap San Lorenzo, which switched fuels entering the Port of Houston and the Mexican Ports of Veracruz and Altamira. Operational and cost aspects were also noted. (2) Emissions reductions were quantified through both a calculation approach based on fuel use of the Maersk Line vessel Roubaix and in-stack monitoring of emissions from the Hamburg Süd Cap San Lorenzo. Pollutant emissions including PM, SO(x), NO(x), and PM component speciation were sampled during use of both fuels. These observations showed reductions (1-6%) in NO

    Maximizing profits is the ultimate business objective in all drilling and completion operations. By far and away the biggest contributor to profits is the productivity of the well. Reliability and costs certainly impact profits; however, they pale in comparison to productivity when a rigorous calculation of net present value is performed. The simplest and most effective way to improve productivity is to increase the quantity of net reservoir exposed to the wellbore. A horizontal trajectory is the ultimate way to maximize the length of formation exposed to the wellbore. Drilling completion technology development over the last several years has made the use of horizontal wellbores in unconsolidated formations practical. Utilizing a unique mixture of new and existing technology, BP recently brought their first horizontal well in the Gulf of Mexico on line in record setting fashion. The planning, installation and results of this team effort are detailed in this operations oriented paper

  2. Preliminary observations of environmental damage due to the Gulf War

    International Nuclear Information System (INIS)

    El-Baz, F.

    1992-01-01

    Preparing for and conducting the Gulf War resulted in much damage to the environment of the region. The first and most visible effect is related to the damage caused by oil well fires in terms of air pollution as well as the potential damage to the petroleum reservoirs. The second detrimental effect has been caused by the oil spill in the Gulf water. Hundreds of miles of the western coastline of the Gulf are already covered with oil. Petroleum 'mats' have settled on coral reefs and have reduced Gulf water productivity. Foremost among the irreparable damages are changes to the terrain due to the digging of trenches, building walls of soil and otherwise disturbing the desert pavement in and around Kuwait. Disruption of the, usually, one-grain thick layer of pebbles on the desert floor exposes soil to wind action. Changing the contours of the normally flat land increases resistance to the wind and increases the potential of particle transport until the land is peneplained. This condition will increase the frequency and the ferocity of dust storms in the region. It will also result in the formation of new sand dunes; sand drifts already exist along roads in northern Kuwait. It is believed that the detrimental effects on the atmosphere will last for years, on the Gulf water for decades, and on the desert surface for centuries. (author). 12 refs, 1 fig

  3. Pollution in the Gulf: Monitoring the marine environment

    International Nuclear Information System (INIS)

    Fowler, S.W.

    1993-01-01

    More than 2 years after the Gulf conflict, scientists are continuing to keep a close watch on marine pollution stemming from the war. Following the conflict in early 1991, major concern was raised worldwide when an estimated four to eight million barrels of crude oil were directly released into the Persian Gulf from the Sea Island terminal in Kuwait. Such amounts clearly made it the largest oil spill in history. The catastrophe was exacerbated when Kuwaiti oil fields were ignited. The magnitude of the pollution, and the types of toxic contaminants involved, led to a worldwide response through the United Nations system. An inter-agency plan of action was developed quickly. As one of its steps, the co-ordinating agency - the United Nations Environment Programme (UNEP) - asked the IAEA's Marine Environment Laboratory (MEL) in Monaco to help make a preliminary assessment of the situation. The Laboratory's main goal in initial surveys was to map the extent and general degree of the war-related pollution throughout the Gulf. Since the initial surveys were done, IAEA-MEL scientists have been engaged in regional follow-up activities in ongoing attempts to obtain a clearer picture of the oil pollution's effects on the Gulf's marine environment. This article highlights the laboratory's work in the Gulf following the 1991 conflict, within the context of co-operative programmes and projects. 1 fig

  5. Gulf team delivers on DP drillship promise

    2001-06-01

    The technological achievements of the project by Amoco and BP to complete a deepwater subsea well in the Gulf of Mexico from a dynamically positioned (DP) vessel are described. In 2000, the dual activity drillship, Discoverer Enterprise (owned by Transocean Sedco Forex), completed the Nile well in the Viosca Knoll area and then the King Well in Mississippi Canyon Block 85. Stringent safety and environmental protection criteria imposed by Amoco and BP drove the design of the Dril-Quip subsea wellhead to ensure that the wellhead profile and connector coped with the worst case scenario. BP also specified a disconnect system that would secure the well in less than a minute. The SenTREE 7 and Commander telemetry systems developed by Schlumberger, the components of the work string and test work with the Nile well to ensure BP conditions were met and that the perforation and surge procedure proceeded successfully are explained. The time reduction achieved by using large DP drillships and future BP plans are outlined.

  6. Manatees in the Gulf of Mexico

    Bonde, Robert K.; Lefebvre, Lynn W.

    2001-01-01

    The endangered Florida manatee (Trichechus manatus latirostris) inhabits rivers and estuaries along both coasts of Florida and, to a lesser extent, adjacent states (Figure 1). Since 1990, documented sightings of manatees outside of Florida have been increasing. This increase in sightings probably represents northward shifts in manatee distribution made possible by man-made sources of warm water (i.e., industrial effluents), as well as a decade of relatively warm winters. The most likely source of emigrants on the Gulf coast is the population of manatees that overwinter in the headwaters of the Crystal and Homosassa Rivers, Citrus County, FL. This group of manatees has undergone a steady increase in numbers, (approximately 7% per year from 1977-1991; Eberhardt and O’Shea 1995). Some emigrants may also come from the Tampa-Ft. Myers region, where human impacts on habitat are greater. Manatees are intelligent, long-lived mammals that appear to adapt readily to new environments and situations. However, manatees have relatively low metabolic rates, and cold winter temperatures restrict their northern distribution.

    Stevens, P.

    1992-01-01

    This report considers the path of international crude oil prices for the remainder of the decade. The report intends to concentrate on the role of the main Gulf oil producing states. Specifically, it seeks to consider the impact of the Iraqi invasion of Kuwait and its aftermath on the Gulf's role in the oil price equation. The report begins by developing an analytical framework which allows the relevant driving forces to be placed in context. From this framework, three issues will emerge central to the Gulf's role in the determination of oil prices: the size and distribution of any excess capacity to produce crude oil; the pricing objectives of those who control that excess capacity; and finally the cohesion of those who control the excess capacity.

  3. Sea surface temperature and Ekman transport in the Persian Gulf

    Directory of Open Access Journals (Sweden)

    E. H.

    2002-12-01

    Full Text Available   The wind drift motion of the water which is produced by the stress of the wind exerted upon the surface of the ocean is described by Ekmans theory (1905. Using the mean monthly values for the wind stress and SST, seasonal Ekman transport for the Persian Gulf was computed and contoured. The geostrophic winds have combined with the SST to estimate the effect of cooling due to Ekman transport of colder northern waters and inflow from the Oman Sea. The monthly SST mainly obtained from the 10 10 grided data of Levitus atlas and Hormuz Cruis Experiment for 1997.   Analyses show a NW to SE Ekman transport due to wind stress and significant interannual variability of SST on sea surface in the Persian Gulf. The seasonal variation of SST shows a continental pattern due to severe interaction between the land and sea. But these variations somehow moderates because of Ekman transport in Persian Gulf.

    "This essay analyses some aspects of the in-migration flows to the Gulf countries, coming from other Arab countries as well as developing nations. Since the 80's, the Gulf countries have endorsed a restrictive policy concerning manpower import, even though they still need foreign workers. The Gulf countries pursue this policy as they fear that the presence of millions of foreign labourers will create social tension. The situation of the foreign labour force is uncertain and is bound to the role of the middleman, the local kafil, and that of the recruiting agencies. Rotation of foreign workers is very high. It has reached the 10 million mark in ten years." (SUMMARY IN ENG) excerpt

    The geologic setting in the deep-water (depths greater than 1,500 feet) Gulf of Mexico is very favorable for the existence of large, commercial hydrocarbon accumulations. These areas have active salt tectonics that create abundant traps, underlying mature Mesozoic source rocks that can be observed expelling oil and gas to the ocean surface, and good quality reservoirs provided by turbidite sand deposits. Despite the limited amount of drilling in the deep-water Gulf of Mexico, 11 deep-water accumulations have been discovered which, when developed, will rank in the top 100 largest fields in the Gulf of Mexico. Proved field discoveries (those with announced development plans) have added over 1 billion barrels of oil equivalent to Gulf of Mexico reserves, and unproved field discoveries may add to additional billion barrels of oil equivalent. The Minerals Management Service, United States Department of the Interior, has completed a gulf-wide review of over 1,086 oil and gas fields and placed every pay sand in each field into a hydrocarbon play (plays are defined by chronostratigraphy, lithostratigraph, structure, and production). Seven productive hydrocarbon plays were identified in the deep-water northern Gulf of Mexico. Regional maps illustrate the productive limits of each play. In addition, field data, dry holes, and wells with sub-economic pay were added to define the facies and structural limits for each play. Areas for exploration potential are identified for each hydrocarbon play. A type field for each play is chosen to demonstrate the play's characteristics

    Different severe accident sequences employing the MELCOR code, version 1.8.4 QK, have been simulated at the Grand Gulf Nuclear Station (Grand Gulf). The postulated severe accidents simulated are two low-pressure, short-term, station blackouts; two unmitigated small-break (SB) loss-of-coolant accidents (LOCAs) (SBLOCAs); and one unmitigated large LOCA (LLOCA). The purpose of this study was to calculate best-estimate timings of events and source terms for a wide range of severe accidents and to compare the plant response to these accidents

    Abstract: Conservation of sea snakes is virtually nonexistent in Asia, and its role in human–snake interactions in terms of catch, trade, and snakebites as an occupational hazard is mostly unexplored. We collected data on sea snake landings from the Gulf of Thailand, a hotspot for sea snake harvest...... years), and the treatment of sea snake bites with rhinoceros horn. Emerging markets in Southeast Asia drive the harvest of venomous sea snakes in the Gulf of Thailand and sea snake bites present a potentially lethal occupational hazard.

    The results of measurements of 90 Sr in water, coral, hermit crabs and molluscs from the western Gulf of Mexico and in fresh water molluscs from Canyon Lake, Texas are reported. Preparation of samples for measurement in the anticoincidence mode in a lead shielded flow proportional counter is described. The measured value of 0.095 +- 0.003 pCi/litre for Gulf water is in accord with literature values. Concentration factors for 90 Sr are apparently 1 for coral. The activity incorporated into shells normalized to calcium content, decreases from Galveston to Campeche Bay. (U.K.)

  9. On the Loop Current Penetration into the Gulf of Mexico

    The Gulf of Mexico Loop Current generally intrudes some distance into the Gulf of Mexico before shedding an anticyclonic eddy and retreating back to its more direct entry to exit pathway. The control of this aperiodic process remains only partially known. Here we describe the evolution of the Loop Current throughout the era of satellite altimetry, and offer a mechanistic hypothesis on Loop Current intrusion. As a complement to the known effects of Loop Current forcing on the west Florida shelf circulation, we argue that the west Florida shelf, in turn, impacts the Loop Current evolution. A Self-Organizing Map analysis shows that anomalous northward penetrations of the Loop Current into the Gulf of Mexico occur when the eastern side of Loop Current is positioned west from the southwest corner of the west Florida shelf, whereas the more direct inflow to outflow route occurs when the eastern side of the Loop Current comes in contact with the southwest corner of the west Florida shelf. In essence, we argue that the west Florida shelf anchors the Loop Current in its direct path configuration and that farther northward penetration into the Gulf of Mexico occurs when such anchoring is released. To test of this hypothesis heuristically, we estimate that the dissipation and buoyancy work due to known Loop Current forcing of the west Florida shelf circulation (when in contact with the southwest corner) may exceed the pressure work required for the Loop Current to advance against the ambient Gulf of Mexico fluid.Plain Language SummaryThe Gulf of Mexico Loop Current may intrude far into the Gulf of Mexico or take a more direct entry to exit pathway. Such Loop Current behaviors are described using remote observations by satellites, and a heuristic hypothesis on the control of Loop Current intrusion is presented. We argue that energy dissipation and buoyancy work by the west Florida shelf circulation, when the Loop Current contacts the southwest corner of the west Florida shelf

    2004-01-01

    The origin of the problems of the Arabian-Persian gulf is the delimitation of the maritime borders between the different bordering states and the exploitation rights of the offshore fields. Despite some bilateral agreements, the non-ratification by two bordering states of the United Nations convention on sea rights, deprives some negotiations of any legal framework. The Hormuz strait, the only opening of the gulf towards the Indian ocean, is tightly controlled by maritime powers which will never accept any interference with the maritime circulation in this pathway of considerable importance for petroleum transportation and for the world economy.

    Almost two-thirds of proven oil and a third of world natural gas resources are in the Persian Gulf countries. Unfortunately strategic region of Persian Gulf in the past three decades faced with many security challenges due to wars and political conflicts. For security in this region, there are several methods such as military treaties between regional countries or Military presence of foreign countries, but historical evidence has shown, none of them could not guarantee the stable security in this region. The regional cooperation between countries can be replaced to mentioned methods. IPI Gas pipeline is an objective sample for this regional cooperation.

    Surface sediment samples from Strymonikos and Ierissos Gulfs were analyzed for Cu, Pb, Zn, Cr and Ni. The results showed that the sediment of Ierissos Gulf is more polluted with Cu, Pb, and Zn as compared to that of Strymonikos Gulf. The benthal area located off the load-out facility of the mining operations in the town of Stratoni, in Ierissos Gulf is established as the most polluted region. The distribution of Cr and Ni in both gulfs indicates the natural origin of these metals with the weathering of Strymon River and of other smaller rivers rocks being responsible for their enrichment.

    In recent years, significant progress has been made in the development of high-resolution ocean reanalysis products. This paper compares aspects of the Gulf Stream (GS) from the Florida Straits to south of the Grand Banks-particularly Florida Strait transport, separation of the GS near Cape Hatteras, GS properties along the Oleander Line (from New Jersey to Bermuda), GS path, and the GS north wall positions-in 13 widely used global reanalysis products of various resolutions, including two unconstrained products. A large spread across reanalysis products is found. HYCOM and GLORYS2v4 stand out for their superior performance by most metrics. Some common biases are found in all discussed models; for example, the velocity structure of the GS near the Oleander Line is too symmetrical and the maximum velocity is too weak compared with observations. Less than half of the reanalysis products show significant correlations (at the 95% confidence level) with observations for the GS separation latitude at Cape Hatteras, the GS transport, and net transport across Oleander Line. The cross-stream velocity structure is further discussed by a theoretical model idealizing GS as a smoothed PV front.

    Full Text Available The settlement of P.T.E., the Multifunctional Centre to serve the Nautical and Technological District of North-East Sardinia, situated on a stretch of coastline north of the Gulf of Olbia, forces us to think about what kind of relationship could be established between the architecture and surrounding environment, strongly characterized on an urbanistic and landscape level. The extension of the productive area denotes the hard strokes of the intensive anthropization of the land, in one of the most beautiful and evocative places in the Gulf. This undefined stretch of coast is the only one to be left undeveloped in the area and it still evokes the original natural landscape. The rigorous and elementary geometry of the industrial area defines the rules of the various buildings as an inevitable emanation. The buildings are designed with the same logic “box” of the urbanity production, made up of many hangers. The disposition of the buildings is also influenced by the irregular and indented coastline and by the will to define a visual screen against industrial settlements and buildings. A distinguishing characteristic marks the uniqueness and rarity of this project: a large blue canopy, suspended in the sky, hovering and resting on buildings, setting the whole complex in a unitary gesture, otherwise fragmented. It is simultaneously a dividing line and threshold, giving evidence to the area of transition between the city and the industrial-technological trade fair grounds, between the city’s architecture and the nature of the sea, between the shadows and the light. It’s an introductory episode, as the doorway and threshold, emphasizing the “brackets”, the exceptional nature of this settlement, the “window”, from which we can look into and see out of it, depending on ones point of view.

  16. Gulf of Aqaba Field Trip - Datasets

    2013-11-01

    OBJECTIVE: In this work we use geophysical methods to locate and characterize active faults in alluvial sediments. INTRODUCTION: Since only subtle material and velocity contrasts are expected across the faults, we used seismic refraction tomography and 2D resistivity imaging to locate the fault. One seismic profile and one 2D resistivity profile are collected at an alluvial fan on the Gulf of Aqaba coast in Saudi Arabia. The collected data are inverted to generate the traveltime tomogram and the electric resistivity tomogram (ERT). A low velocity anomaly is shown on the traveltime tomogram indicates the colluvial wedge associated with the fault. The location of the fault is shown on the ERT as a vertical high resistivity anomaly. Two data sets were collected at the study site to map the subsurface structure along a profile across the known normal fault described above. The first data set is a seismic refraction data set and the second is a 2D resistivity imaging data set. A total of 120 common shot gathers were collected (MatLab and DPik format). Each shot gather has 120 traces at equal shot and receiver intervals of 2.5 m. The total length of the profile is 297.5 m . Data were recorded using a 1 ms sampling interval for a total recording time of 0.3 s. A 200 lb weight drop was used as the seismic source, with 10 to 15 stacks at each shot location. One 2D resistivity profile is acquired at the same location and parallel to the seismic profile. The acquisition parameters of the resistivity profile are: No. of nodes: 64, Node interval: 5 m, Configuration Array: Schlumberger-Wenner, Total profile length: 315 m, Both seismic and resistivity profiles share the same starting point at the western end of the profile.

    INTRODUCTION: Compared with controls, up to six years after their return, Danish Gulf War veterans have a significantly higher prevalence of self-reported neuropsychological symptoms, potentially as a result of neurotoxic exposure during deployment. We tested the hypotheses that: 1) GW veterans...... of neuropsychological symptoms, and stratified according to SCL-90-R score, no trends were found suggesting reduced motor function with increasing symptoms. Of nine dimensions constructed on the basis of the SCL-90-R items, six were significantly associated with being a Gulf War veteran. Statistically, the strongest...... would perform less well than controls using a computerized neuromotor test battery; and that 2) GW veterans have a psychological profile different from that of controls.

    These remotely sensed, geographically referenced elevation measurements of Lidar-derived bare earth (BE) topography were produced as a collaborative effort between the U.S. Geological Survey (USGS), Florida Integrated Science Center (FISC), St. Petersburg, FL; the National Park Service (NPS), Gulf Coast Network, Lafayette, LA; and the National Aeronautics and Space Administration (NASA), Wallops Flight Facility, VA. The purpose of this project is to provide highly detailed and accurate datasets of select barrier islands and peninsular regions of Louisiana, Mississippi, Alabama, and Florida, acquired on June 27-30, 2007. The datasets are made available for use as a management tool to research scientists and natural resource managers. An innovative airborne Lidar instrument originally developed at the NASA Wallops Flight Facility, and known as the Experimental Advanced Airborne Research Lidar (EAARL), was used during data acquisition. The EAARL system is a raster-scanning, waveform-resolving, green-wavelength (532-nanometer) Lidar designed to map near-shore bathymetry, topography, and vegetation structure simultaneously. The EAARL sensor suite includes the raster-scanning, water-penetrating full-waveform adaptive Lidar, a down-looking red-green-blue (RGB) digital camera, a high-resolution multi-spectral color infrared (CIR) camera, two precision dual-frequency kinematic carrier-phase GPS receivers, and an integrated miniature digital inertial measurement unit which provide for submeter georeferencing of each laser sample. The nominal EAARL platform is a twin-engine Cessna 310 aircraft, but the instrument may be deployed on a range of light aircraft. A single pilot, a Lidar operator, and a data analyst constitute the crew for most survey operations.

  20. Lagrangian motion, coherent structures, and lines of persistent material strain.

    2013-01-01

    Lagrangian motion in geophysical fluids may be strongly influenced by coherent structures that support distinct regimes in a given flow. The problems of identifying and demarcating Lagrangian regime boundaries associated with dynamical coherent structures in a given velocity field can be studied using approaches originally developed in the context of the abstract geometric theory of ordinary differential equations. An essential insight is that when coherent structures exist in a flow, Lagrangian regime boundaries may often be indicated as material curves on which the Lagrangian-mean principal-axis strain is large. This insight is the foundation of many numerical techniques for identifying such features in complex observed or numerically simulated ocean flows. The basic theoretical ideas are illustrated with a simple, kinematic traveling-wave model. The corresponding numerical algorithms for identifying candidate Lagrangian regime boundaries and lines of principal Lagrangian strain (also called Lagrangian coherent structures) are divided into parcel and bundle schemes; the latter include the finite-time and finite-size Lyapunov exponent/Lagrangian strain (FTLE/FTLS and FSLE/FSLS) metrics. Some aspects and results of oceanographic studies based on these approaches are reviewed, and the results are discussed in the context of oceanographic observations of dynamical coherent structures.

    Two species of Atarbolana (Cirolanidae: Isopoda) from the intertidal zone of the Gulf of Oman and the Persian Gulf were studied and redescribed. The known distribution of this small genus is limited to the northern areas of the Indian Ocean, from the Pakistan coasts to the Persian Gulf. The analyses of DNA barcodes as well as detailed morphological studies clearly support the existence of three distinct Atarbolana species along the coastal zone of the Persian Gulf and northern Arabian Sea. Furthermore, A. dasycolus Yasmeen, 2004 is synonymized with A. setosa Javed and Yasmeen, 1989.

    The oil and gas exploration and production business environment has presented many challenges over the last decade, notably price volatility and rising costs. Managing the margin and changing a company's cost structure to improve the bottom line is a major issue with company executives. The experiences of Oryx Energy Company since its spinoff from Sun Company in 1988 are used as an example of a company makeover. A generalized exploration and production income statement is employed to present industry cost/portfolio relationships and strategies for improving the bottom line. At Oryx, three major strategies were set in place to enhance shareholder value: an increased emphasis on applied technology, including horizontal drilling, advanced 3-dimensional seismic prospecting, and intensive use of interactive computer workstations; international expansion; and an emphasis on the U.S. Gulf of Mexico, deemphasizing the onshore U.S. and the gas processing business. Specific strategies are outlined in the areas of increasing revenues, reducing production cost and exploration expense, and controlling general and administrative expenses. 8 refs., 18 figs., 2 tabs

    Full Text Available Background: Pre-clinical studies for isolation and purification of marine compounds continued at an active pace since the last decade. Today, more than 60% of the anticancer drugs commercially available are of naturally origin thus the sea is a very favorable bed for the discovery of novel anticancer agents. Methods: A total of known 611 seashells species in the Persian Gulf were investigated for synonymy in OBIS database. Then, all the species, including their synonymy were searched in PubMed databse to find their isolated bioactive agents. Results: From 611 known seashells in the Persian Gulf, 172 genera/species had bioactive compounds. Anticancer agents were isolated and purified for 8 genera. These compounds had various structures they were polypeptide, polysaccharide, glycoprotein, alkaloid, cerebroside, and cembranoid which had different mechanism of actions including induction of apoptosis, destroying the skeletal structures of the cells, immune bioactivity and inhibition of topoisomerase I. Spisulosine is the only anticancer agent which is currently under clinical trial. Conclusions: Although, the known seashells from the Persian Gulf have potential anticancer and cytotoxic compounds but a very few investigations had been reported. Further investigations for isolation and purification on bioactive compounds from seashells of the Persian Gulf is recommended.

    Blooms of the toxic marine dinoflagellate Karenia brevis cause massive fish kills and other public health and economic problems in coastal waters throughout the Gulf of Mexico [Steidinger, 2009]. These harmful algal blooms (HABs) are a gulf-wide problem that require a synoptic observing system for better serving decision-making needs. The major nutrient sources that initiate and maintain these HABs and the possible connectivity of blooms in different locations are important questions being addressed through new collaborations between Mexican and U.S. researchers and government institutions. These efforts were originally organized under the U.S./Mexico binational partnership for the HABs Observing System (HABSOS), led by the U.S. Environmental Protection Agency's Gulf of Mexico Program (EPAGMP) and several agencies in Veracruz, Mexico, since 2006. In 2010 these efforts were expanded to include other Mexican states and institutions with the integrated assessment and management of the Gulf of Mexico Large Marine Ecosystem (GoMLME) program sponsored by the Global Environment Facility (GEF), the United Nations Industrial Development Organization (UNIDO), the Secretaría de Medio Ambiente y Recursos Naturales (SEMARNAT), and the National Oceanic and Atmospheric Administration (NOAA).

    The yearlong monthly mean satellite data of the geostrophic velocities, the sea surface temperature and the chlorophyll-a values were used to elucidate any possible pathway among the different coral reef systems of the Western Gulf of Mexico (WGM). The geostrophic current velocities suggested different pathways connecting the coral reef areas. The typical coastal alongshore pathway constricted to the continental shelf, and two open ocean pathway, the first connecting the Campeche Reef System (CRS) with the Veracruz (VRS) and Tuxpan-Lobos Reef Systems (TLRS), and the second pathway connecting the Tuxpan-Lobos Reef System with the Flower Garden Reef System (FGRS). According to the pathways there should be more larvae transport from the southern Gulf of Mexico reef systems toward the FGRS than the other way. The connection from the southern Gulf of Mexico toward the FGRS took place during January, May, July, August and September (2015), while the connection from the FGRS toward the southern Gulf of Mexico reef system took place during January and February (2015), this was also suggested via model outputs. The density radio (R) was used as a first approximation to elucidate the influence of the freshwater continental discharges within the continental shelf. All coral reef areas were located where the Chlorophyll-a monthly mean values had values bellow 1 mg m- 2 with a density radio between 0 and 1, i.e. under the influence of continental discharges.

  11. On depleted uranium: gulf war and Balkan syndrome.

    Science.gov (United States)

    Duraković, A

    2001-04-01

    The complex clinical symptomatology of chronic illnesses, commonly described as Gulf War Syndrome, remains a poorly understood disease entity with diversified theories of its etiology and pathogenesis. Several causative factors have been postulated, with a particular emphasis on low level chemical warfare agents, oil fires, multiple vaccines, desert sand (Al-Eskan disease), botulism, Aspergillus flavus, Mycoplasma, aflatoxins, and others, contributing to the broad scope of clinical manifestations. Among several hundred thousand veterans deployed in the Operation Desert Storm, 15-20% have reported sick and about 25,000 died. Depleted uranium (DU), a low-level radioactive waste product of the enrichment of natural uranium with U-235 for the reactor fuel or nuclear weapons, has been considered a possible causative agent in the genesis of Gulf War Syndrome. It was used in the Gulf and Balkan wars as an armor-penetrating ammunition. In the operation Desert Storm, over 350 metric tons of DU was used, with an estimate of 3-6 million grams released in the atmosphere. Internal contamination with inhaled DU has been demonstrated by the elevated excretion of uranium isotopes in the urine of the exposed veterans 10 years after the Gulf war and causes concern because of its chemical and radiological toxicity and mutagenic and carcinogenic properties. Polarized views of different interest groups maintain an area of sustained controversy more in the environment of the public media than in the scientific community, partly for the reason of being less than sufficiently addressed by a meaningful objective interdisciplinary research.

  12. Petroleum service projects in the Gulf of Guinea

    Ken-Worgu, Kenneth Chukwumeka

    2011-07-01

    The goal of this record of study is to examine the major facets involved in managing several petroleum service projects located in three different countries in the Gulf of Guinea simultaneously, while effectively engaging in business development activities for the Oil and Industrial Services Group (OIS). This work also furnishes adequate background on related subject matters to enable understanding of the projects presented. The petroleum services sector is the back bone of the oil and gas industry. Services companies are vital to the success of all petroleum and energy producers in the USA, the Gulf of Guinea and the world. There is a need and demand for these service companies because they play various roles such as logistics, drilling, construction, dredging, pipe laying, procurement, food supply, human resource supply, etc. The Gulf of Guinea comprises of countries from west and central Africa. This project was limited to Nigeria, Equatorial Guinea and Cameroon. This area holds the largest petroleum reserves in Africa and plays a vital role in the global supply of petroleum. The Oil and Industrial Services Group (OIS), plans to establish herself as one of the leading petroleum service companies in this gulf. To manage this expansion, I have taken the role of Gulf of Guinea manager to apply my background as a petroleum engineer as well as my business skills to build a successful division of the company. This work provides a record of study of the management of services, projects and contracts carried out by the OIS group in the gulf of Guinea. The following are the specific projects in the Gulf of Guinea that I participated in: Managing delivering, maintenance and marketing of offshore vessels, Offshore pipe laying project, Integrated pipeline maintenance project, Development a petroleum technical training facilities, Agbami pipe insulation project, Engineering lift project and Capital budgeting analysis for potential investments.

  13. Blood Biomarkers of Chronic Inflammation in Gulf War Illness.

    Directory of Open Access Journals (Sweden)

    Gerhard J Johnson

    Full Text Available More than twenty years following the end of the 1990-1991 Gulf War it is estimated that approximately 300,000 veterans of this conflict suffer from an unexplained chronic, multi-system disorder known as Gulf War Illness (GWI. The etiology of GWI may be exposure to chemical toxins, but it remains only partially defined, and its case definition is based only on symptoms. Objective criteria for the diagnosis of GWI are urgently needed for diagnosis and therapeutic research.This study was designed to determine if blood biomarkers could provide objective criteria to assist diagnosis of GWI.A surveillance study of 85 Gulf War Veteran volunteers identified from the Department of Veterans Affairs Minnesota Gulf War registry was performed. All subjects were deployed to the Gulf War. Fifty seven subjects had GWI defined by CDC criteria, and 28 did not have symptomatic criteria for a diagnosis of GWI. Statistical analyses were performed on peripheral blood counts and assays of 61 plasma proteins using the Mann-Whitney rank sum test to compare biomarker distributions and stepwise logistic regression to formulate a diagnostic model.Lymphocyte, monocyte, neutrophil, and platelet counts were higher in GWI subjects. Six serum proteins associated with inflammation were significantly different in GWI subjects. A diagnostic model of three biomarkers-lymphocytes, monocytes, and C reactive protein-had a predicted probability of 90% (CI 76-90% for diagnosing GWI when the probability of having GWI was above 70%.The results of the current study indicate that inflammation is a component of the pathobiology of GWI. Analysis of the data resulted in a model utilizing three readily measurable biomarkers that appears to significantly augment the symptom-based case definition of GWI. These new observations are highly relevant to the diagnosis of GWI, and to therapeutic trials.

  14. Characterization of sea floor in Gulf of Mexico

    1986-05-01

    In 1985, the US Geological Survey (USGS) conducted a mapping program in the Gulf of Mexico. Using the GLORIA (Geologic Long-Range Inclined Asdic) side-scan sonar system of the Institute of Oceanographic Sciences, USGS mapped approximately 90,000 nmi/sup 2/ of sea floor in the central and western Gulf of Mexico, seaward of the shelf edge. The Sigsbee Escarpment, the seaward edge of a salt front that extends from the western gulf to just west of the Mississippi Canyon, is marked by piles of debris along its base, and is breached by several submarine channels. One such meandering channel can be traced from the shelf edge, through the maze of diapirs on the slope, and out across the Sigsbee Abyssal Plain. This continuous transport pathway indicates the interaction of salt tectonics on sediment pathways and distribution. Numerous bed forms seaward of the Sigsbee Escarpment suggest that strong bottom currents are present. The northern gulf has three major submarine fans, each with different surface morphologies. The Rio Grande Fan has a braided channel system. The Mississippi Fan has a main channel that can be traced for approximately 100 km across the midfan, but most of the surface of the upper and midfan as well as the channel are buried by submarine slides or debris flows. Desoto Canyon Fan also has a continuous channel that has been filled or overrun in places by massive debris flows. Based on the sonographs, mass wasting appears to be an important process in distributing sediments in the deep water of the central gulf.

    2004-11-01

    The gas hydrates research Consortium (HRC), established and administered at the University if Mississippi's Center for Marine Research and Environmental Technology (CMRET) has been active on many fronts in FY 03. Extension of the original contract through March 2004, has allowed completion of many projects that were incomplete at the end of the original project period due, primarily, to severe weather and difficulties in rescheduling test cruises. The primary objective of the Consortium, to design and emplace a remote sea floor station for the monitoring of gas hydrates in the Gulf of Mexico by the year 2005 remains intact. However, the possibility of levering HRC research off of the Joint Industries Program (JIP) became a possibility that has demanded reevaluation of some of the fundamental assumptions of the station format. These provisions are discussed in Appendix A. Landmark achievements of FY03 include: (1) Continuation of Consortium development with new researchers and additional areas of research contribution being incorporated into the project. During this period, NOAA's National Undersea Research Program's (NURP) National Institute for Undersea Science and Technology (NIUST) became a Consortium funding partner, joining DOE and Minerals Management Service (MMS); (2) Very successful annual and semiannual meetings in Oxford Mississippi in February and September, 2003; (3) Collection of piston cores from MC798 in support of the effort to evaluate the site for possible monitoring station installation; (4) Completion of the site evaluation effort including reports of all localities in the northern Gulf of Mexico where hydrates have been documented or are strongly suspected to exist on the sea floor or in the shallow subsurface; (5) Collection and preliminary evaluation of vent gases and core samples of hydrate from sites in Green Canyon and Mississippi Canyon, northern Gulf of Mexico; (6) Monitoring of gas activity on the sea floor, acoustically

  16. All-Cause Mortality Among US Veterans of the Persian Gulf War

    Science.gov (United States)

    Kang, Han K.; Bullman, Tim

    2016-01-01

    Objective: We determined cause-specific mortality prevalence and risks of Gulf War deployed and nondeployed veterans to determine if deployed veterans were at greater risk than nondeployed veterans for death overall or because of certain diseases or conditions up to 13 years after conflict subsided. Methods: Follow-up began when the veteran left the Gulf War theater or May 1, 1991, and ended on the date of death or December 31, 2004. We studied 621   901 veterans who served in the 1990-1991 Persian Gulf War and 746   247 veterans who served but were not deployed during the Gulf War. We used Cox proportional hazard models to calculate rate ratios adjusted for age at entry to follow-up, length of follow-up, race, sex, branch of service, and military unit. We compared the mortality of (1) Gulf War veterans with non–Gulf War veterans and (2) Gulf War army veterans potentially exposed to nerve agents at Khamisiyah in March 1991 with those not exposed. We compared standardized mortality ratios of deployed and nondeployed Gulf War veterans with the US population. Results: Male Gulf War veterans had a lower risk of mortality than male non–Gulf War veterans (adjusted rate ratio [aRR] = 0.97; 95% confidence interval [CI], 0.95-0.99), and female Gulf War veterans had a higher risk of mortality than female non–Gulf War veterans (aRR = 1.15; 95% CI, 1.03-1.28). Khamisiyah-exposed Gulf War army veterans had >3 times the risk of mortality from cirrhosis of the liver than nonexposed army Gulf War veterans (aRR = 3.73; 95% CI, 1.64-8.48). Compared with the US population, female Gulf War veterans had a 60% higher risk of suicide and male Gulf War veterans had a lower risk of suicide (standardized mortality ratio = 0.84; 95% CI, 0.80-0.88). Conclusion: The vital status and mortality risk of Gulf War and non–Gulf War veterans should continue to be investigated. PMID:28123229

    2017-06-01

    A new record ponyfish, Deveximentum megalolepis Mochizuki and Hayashi, 1989, was documented based on its morphological characteristics and DNA barcode. Fifty specimens were collected from Beibu Gulf of China and identified as D. megalolepis by morphological characterization. The coloration, meristic traits, and morphometric measurements were consistent with previously published records. In general, it is a silver-white, laterally compressed and deep bodied ponyfish with 6-9 rows of scales on cheek; scale rows above lateral line 6-8; scale rows below lateral line 14-17. Mitochondrial cytochrome oxidase I subunit (COI) gene fragment was sequenced for phylogenetic analysis. There is no sequence variation of COI gene between the specimens collected in this study. The genetic distances between D. megalolepis and other congeneric species range from 3.6% to 14.0%, which were greater than the threshold for fish species delimitation. The COI sequence analysis also supported the validity of D. megalolepis at genetic level. However, the genetic distance between Chinese and Philippine individuals was about 1.2% and they formed two lineages in gene tree, which may be caused by the geographical distance.

    An assessment unit (AU) for undiscovered continuous “shale” gas in Lower Cretaceous (Aptian and Albian) and basal Upper Cretaceous (lower Cenomanian) rocks in the USA onshore Gulf of Mexico coastal plain recently was defined by the U.S. Geological Survey (USGS). The AU is part of the Upper Jurassic-Cretaceous-Tertiary Composite Total Petroleum System (TPS) of the Gulf of Mexico Basin. Definition of the AU was conducted as part of the 2010 USGS assessment of undiscovered hydrocarbon resources in Gulf Coast Mesozoic stratigraphic intervals. The purpose of defining the Greater Gulf Basin Lower Cretaceous Shale Gas AU was to propose a hypothetical AU in the Cretaceous part of the Gulf Coast TPS in which there might be continuous “shale” gas, but the AU was not quantitatively assessed by the USGS in 2010.

  6. Directed line liquids

    International Nuclear Information System (INIS)

    Kamien, R.D.

    1992-01-01

    This thesis is devoted to the study of ensembles of dense directed lines. These lines are principally to be thought of as polymers, though they also have the morphology of flux lines in high temperature superconductors, strings of colloidal spheres in electrorheological fluids and the world lines of quantum mechanical bosons. The authors discuss how directed polymer melts, string-like formations in electrorheological and ferro-fluids, flux lines in high temperature superconductors and the world lines of quantum mechanical bosons all share similar descriptions. They study a continuous transition in all of these systems, and then study the critical mixing properties of binary mixtures of directed polymers through the renormalization group. They predict the exponents for a directed polymer blend consolute point and a novel two-phase superfluid liquid-gas critical point

  8. Tropical cyclone disasters in the Gulf of Thailand

    Directory of Open Access Journals (Sweden)

    Suphat Vongvisessomjai

    2009-07-01

    Full Text Available The origin of tropical cyclones in the South China Sea is over a vast deep sea, southeast of the Philippines. The severetropical cyclones in summer with northerly tracks attack the Philippines, China, Korea and Japan, while the moderate ones inthe rainy season with northwesterly tracks pass Vietnam, Laos and northern Thailand. In October, November and December, the tropical cyclones are weakened and tracks shift to a lower latitude passing the Gulf of Thailand. Tropical cyclone disasters in the Gulf of Thailand due to strong winds causing storm surges and big waves or heavy rainfall over high mountains in causing floods and land slides result in moderate damages and casualties. Analyses are made of six decades of data of tropical cyclones from 1951-2006 having averaged numbers of 3 and 13 in Thailand and the South China Sea respectively. Detailed calculation of surges and wave heights of the 5 disastrous tropical cyclones in the Gulf of Thailand reveal that the Upper Gulf of Thailand with a limited fetch length of about 100 km in north/south direction and about 100 km width in the east/west direction, resulted in a limited maximum wave height of 2.3-2.5 m and maximum storm surge height of 1.2 m generated by Typhoon Vae (1952, while the east coast, with longer fetch lengthbut still limited by the existence of its shoreline, resulted in an increased maximum wave height of 4 m and maximum storm surge height of 0.6 m in the Upper Gulf of Thailand generated by Typhoon Linda (1997. These are the Probable Maximum Cyclones here.The southern shoreline, with unlimited fetch length on the east by tropical cyclones approaching from the South China Sea, generated maximum wave height of 6-11 m by Typhoon Gay (1989, resulting in more casualties and damages. Note that storm surges on the southern shorelines with steep slopes are small due to the short distance of shallow shorelines in receiving wind stresses for piling up sea levels. These disasters can be

    2017-08-01

    Obesity has become an epidemic in the Arabian Gulf, with the prevalence of obesity according to the latest report from the World Health Organization (WHO) showing the gulf region to be countries with the highest incidence of obesity in the 30% plus group. This study aims to examine publications on bariatric surgery and compare them with the other countries with a high incidence of obesity in the world. A literature review on bariatric surgery published from the earliest detected year of publication up until March 2016 using SCOPUS, PubMed, Ovid, and Google Scholar was conducted. Individual papers were assessed for types of surgery, preoperative measures, names of journals, authors, and outcomes. The data was analyzed using Endnote library and SPSS. Key words used in the search included "Bariatric Surgery," "Arabian Gulf," "Kuwait," "Qatar," "Saudi Arabia," "United Arab Emirates," "Oman," "USA," "Australia," "weight loss surgery," "sleeve gastrectomy," "gastric bypass," "gastric band," "mini-gastric bypass," "biliropancreatic diversion," "duodenal switch," and "intragastric balloon." Original papers, systematic reviews and case reports were included. From our review, the gastric sleeve proved to be the most popular published on procedure in the Arabian Gulf, whereas the USA had the highest percentage of gastric bypass surgeries and Australia had equivalent numbers when it came to gastric bypass and band. The numbers of studies from Saudi Arabia, Kuwait, UAE, Bahrain, Qatar, and Oman were 70, 44, 20, 7, 6, and 0, respectively. The mean impact factor of the published articles was 2.53 +/- 1.76 SD. Most of the publications were published in Obesity Surgery (29%), Surgery for Obesity and Related Diseases (5%), and Surgical Endoscopy (5%). The Arabian Gulf has both the highest percentage of bariatric procedures performed as well as the highest prevalence of obesity. However, they have the lowest number of publications and research when compared to their western

  10. Covariant electromagnetic field lines

    Hadad, Y.; Cohen, E.; Kaminer, I.; Elitzur, A. C.

    2017-08-01

    Faraday introduced electric field lines as a powerful tool for understanding the electric force, and these field lines are still used today in classrooms and textbooks teaching the basics of electromagnetism within the electrostatic limit. However, despite attempts at generalizing this concept beyond the electrostatic limit, such a fully relativistic field line theory still appears to be missing. In this work, we propose such a theory and define covariant electromagnetic field lines that naturally extend electric field lines to relativistic systems and general electromagnetic fields. We derive a closed-form formula for the field lines curvature in the vicinity of a charge, and show that it is related to the world line of the charge. This demonstrates how the kinematics of a charge can be derived from the geometry of the electromagnetic field lines. Such a theory may also provide new tools in modeling and analyzing electromagnetic phenomena, and may entail new insights regarding long-standing problems such as radiation-reaction and self-force. In particular, the electromagnetic field lines curvature has the attractive property of being non-singular everywhere, thus eliminating all self-field singularities without using renormalization techniques.

    Coral reef science has grown exponentially in recent decades in the Gulf. Analysis of literature from 1950 to 2012 identified 270 publications on coral reefs in the Gulf, half of which were published in just the past decade. This paper summarizes the growth and evolution of coral reef science in the Gulf by examining when, where and how research has been conducted on Gulf reefs, who conducted that research, and what themes and taxa have dominated scientific interest. The results demonstrate that there has been significant growth in our understanding of the valuable coral reefs of the Gulf, but also highlight the fact that we are documenting an increasingly degraded ecosystem. Reef scientists must make a concerted effort to improve dialogue with regional reef management and decision-makers if we are to stem the tide of decline in coral reefs in the Gulf.

    continuous map of gravity anomalies and a continuous map of gravity by using spatial interpolation methods and to evaluate errors; 2) to solve the Laplace boundary value problem and evaluate errors; 3) to evaluate precision of the local geoid by using geospatial statistical tools and numerical techniques. This dissertation investigates modeling of the geoid, especially the gravimetric equipotential surface that approximates mean sea level, in the coastal areas of the Gulf of Mexico as well as errors in the geoid determination. The document begins with Chapter 1 which introduces the study of this dissertation. Different models of kriging are used to determine the precision of the geoid based on the free-air gravity anomalies data supplied by United States Naval Research Laboratory and the airborne gravity data provided by the U.S. National Geodetic Survey, which can be found in Chapters 2 and 3. Research in Chapters 2 shows that more precise evaluation of errors in gravity anomalies can be achieved by using different models of kriging. Results from Chapters 2 and 3 show that ordinary kriging with the stable semivariogram model provide better predictions. Research results from Chapter 3 provide estimation of maximum possible errors in the calculation of the geoid undulation. The dissertation also investigates behavior of gravity equipotential surfaces around coastal lines and its impact on the geoid evaluation. Chapters 4 and 5 are about evaluation of errors in the Dirichlet problem for calculation of gravity potential with uncertain boundary and boundary values has been achieved by solving the Laplace equation by means of separation of variables. Research has provided a theoretical model in Chapter 4 to estimate very small changes in gravimetric potential relative to the coast. Maximum possible error in the solution of Direchlet problem is determined in Chapter 5. Maximum possible error depends on the errors of boundary values and the precision of the boundary itself.

  14. Surface faults in the gulf coastal plain between Victoria and Beaumont, Texas

    faults identified in subsurface Tertiary sediments. (4) Evidence to support the thesis that surface scarps are the shallow expression of faults extending downward into the Tertiary section is mostly indirect, but nonetheless reasonably convincing. Certainly the patterns of crestal grabens and radiating faults mapped on the surface above salt domes are more than happenstance; analogous fault patterns have been documented around these structures at depth. Similarly, some of the long surface faults not associated with salt domes seem to have subsurface counterparts among known regional growth faults documented through well logs and seismic data. Correlations between surface scarps and faults offsetting subsurface data are not conclusive because of the large vertical distances (1900- 3800 m) involved in making the most of the inferred connections. Nevertheless, the large number of successful correlations - in trend, movement sense, and position - suggests that many surface scarps represent merely the most recent displacements on faults formed during the Tertiary. (5) Upstream-facing fault scarps in this region of low relief can be significant impediments to streams. Locally, both abandoned, mud-filled Pleistocene distributary channels and, more commonly, Holocene drainage lines still occupied by perennial streams reflect the influence of faulting on their development. Some bend sharply near faults and have tended to flow along or pond against the base of scarps; others meander within topographically expressed grabens. Such evidence for Quaternary displacement of the ground surface is widespread in the Texas Gulf coast. In the general, however, streams in areas now offset by faulting show no disruption of their courses where they cross fault scarps. Such scarps are probably very young, and where they can be demonstrated to partly or wholly predate fluid withdrawal, very recent natural fault activity is indicated. (6) Early aerial photographs (1930) of the entire region and

    1988-01-01

    Neutron activation analysis (NAA) with its great sensitivity for a large number of elements has been widely used for marine environmental studies Saronikos Gulf receives combined domestic and industrial effluents of the grater Athens area through the Athens sewage outfall (ASO) at Keratsini Bay, which also receives wastes from discrete industrial sources including a fertilizer plant. Such discharges usually contain high concentrations of heavy metals, which can be dangerous to marine ecosystems and humans. This paper is a review of research and monitoring studies of toxic and other trace elements in marine organisms, seawater, and sediments of Saronikos Gulf by NAA performed over the last 15 yr. The objectives of these studies were (a) to find the fates and pathways of toxic and other trace elements, (b) to estimate the extent of pollution, and (c) to pinpoint and distinguish pollution sources

    Migratory waterfowl may play a role in the ecology and transmission of zoonotic pathogens, given their ability to travel long distances and their use of varied habitats. Our objectives were to estimate the prevalence of Salmonella among waterfowl along the Texas Gulf coast and to characterize the isolates. Faecal samples were collected from hunter-harvested waterfowl at four wildlife management areas from September through November, 2016. Standard bacteriologic culture methods were used to isolate Salmonella from samples, and isolates were characterized by serotyping and anti-microbial susceptibility testing. The apparent prevalence of faecal Salmonella shedding was 0.5% (2/375). Serotypes identified were Thompson and Braenderup, and both isolates were susceptible to all anti-microbial agents tested. Although faecal contamination of agricultural fields or surface waters could serve as a potential source of zoonotic Salmonella transmission, waterfowl along the Gulf coast during the fall hunting season appear to pose minimal risk. © 2017 Blackwell Verlag GmbH.

    The geologic exploration program in the Gulf Coast Salt Dome Region is based on a screening process that includes a series of increasingly detailed studies. The screening procedure takes the following steps: (1) determination of regions for further study (in this case, the salt domes of the interior Gulf Coast); (2) regional surveys and the determination of areas within those regions which are thought to be most suitable and which are recommended for further evaluation (in this case, eight specific salt domes); (3) area characterizations and the determination of locations within the areas which are thought to have a high probability of suitability (in this case, two or three of the eight salt domes); (4) location studies and the determination of a potential repository site, which is thought to be suitable and licensable and which is recommended for completion of site characterization studies

  2. Petroleum hydrocarbons in offshore sediments from the Gulf

    Al-Lihaibi, S.S.; Al-Omran, Laila

    1996-01-01

    Petroleum hydrocarbons in offshore sediments from the central part of the Gulf were measured using fluorescence spectrophotometry. Concentrations varied between 4.0 and 56.2 μg/g wet sediment (expressed as Kuwait Crude Oil equivalents), with an average of 12.3 μ/g. Highest concentrations were recorded in the north-west sector, with concentrations decreasing in a south-westerly direction. No significant correlations were observed between petroleum hydrocarbons and sedimentary organic carbon (r-0.07), 'mud' content (r=0.09), 'sand' content (r= -0.08) or 'gravel' content (r= -0.12). Distributions of oil are considered to relate more closely to prevailing current and localized pollutant sources in the region. Despite the substantial inputs of oil to the Gulf, contamination can be considered comparatively low, possibly reflecting physical processes and biological degradation which accelerate removal of petroleum from this marine environment.

  3. Gulf of Mexico rig activity up, international lags

    1994-01-01

    Demand for jack up and semisubmersible rigs has improved in the Gulf of Mexico following a decline in activity earlier this year. International drilling activity, however, has shown slight declines in several regions. Relatively firm natural gas prices have helped buoy rig activity in North America. Rig day rates have not followed suit, mainly because of the influx of rigs from weaker international markets. Day rates in the US may not increase until international activity picks up and the world-wide drilling market tightens. Oil prices have hit almost $20/bbl, mainly because of the recent oil worker' strike in Nigeria and good demand. Natural gas prices in the US have hovered around $2.00/MMBTU, and many industry analysts expect gas prices to remain strong over the next few years. This paper gives data on drilling rig counts and crude oil and gas prices in the Gulf of Mexico and onshore

    1991-01-01

    Decades of offshore and inland petroleum drilling and production in the Gulf of Mexico and on the Gulf Coast have provided the much needed energy and chemical feedstocks to the nation, and also have made an impact on the environment in the area. Our study showed deposits of contaminated sediment on the ocean floor around offshore platforms, old reserve pits, and dump sites next to many surface facilities and compressor stations. The substances found on the ocean floor and in dump sites are simple or emulsified mixtures of silt, hydrocarbons, and water. The cleaning of the ocean floor and pits is an economic and technical challenge. Hydrocarbons are from crude oil and chemical additions fro various operational necessities, including additions of biocides, corrosion inhibitors, antifreezes, and coagulants. When the new government regulations lower the allowable maximum total organic carbon level to the 50 ppm range, these hydrocarbons can no longer be ignored by drilling and production operators

  7. Free and forced Rossby normal modes in a rectangular gulf of arbitrary orientation

    Science.gov (United States)

    Graef, Federico

    2016-09-01

    A free Rossby normal mode in a rectangular gulf of arbitrary orientation is constructed by considering the reflection of a Rossby mode in a channel at the head of the gulf. Therefore, it is the superposition of four Rossby waves in an otherwise unbounded ocean with the same frequency and wavenumbers perpendicular to the gulf axis whose difference is equal to 2mπ/W, where m is a positive integer and W the gulf's width. The lower (or higher) modes with small m (or large m) are oscillatory (evanescent) in the coordinate along the gulf; these are elucidated geometrically. However for oceanographically realistic parameter values, most of the modes are evanescent. When the gulf is forced at the mouth with a single Fourier component, the response is in general an infinite sum of modes that are needed to match the value of the streamfunction at the gulf's entrance. The dominant mode of the response is the resonant one, which corresponds to forcing with a frequency ω and wavenumber normal to the gulf axis η appropriate to a gulf mode: η =- β sin α/(2ω) ± Mπ/W, where α is the angle between the gulf's axis and the eastern direction (+ve clockwise) and M the resonant's mode number. For zonal gulfs ω drops out of the resonance condition. For the special cases η = 0 in which the free surface goes up and down at the mouth with no flow through it, or a flow with a sinusoidal profile, resonant modes can get excited for very specific frequencies (only for non-zonal gulfs in the η = 0 case). The resonant mode is around the annual frequency for a wide range of gulf orientations α ∈ [40°, 130°] or α ∈ [220°, 310°] and gulf widths between 150 and 200 km; these include the Gulf of California and the Adriatic Sea. If η is imaginary, i.e. a flow with an exponential profile, there is no resonance. In general less modes get excited if the gulf is zonally oriented.

  9. Mercury in contaminated coastal environments; a case study: the Gulf of Trieste.

    Some general facts, uncertainties and gaps in current knowledge of Hg cycling in coastal and oceanic environments are given. As a case study the Gulf of Trieste is chosen. The Gulf is subject to substantial Hg pollution, originating from the Soca river, that drains the cinnabar deposits of the world's second largest Hg mining area, Idrija, Slovenia. The Gulf belongs to one of the most polluted areas in the Mediterranean. Apart from Hg problems, the Gulf is also a subject to industrial and sewage pollution. Due to deteriorating water quality in the Gulf there is a great concern that Hg can be remobilized from sediments to the water column as well as enhance methylation rates which may consequently increase already elevated Hg levels in aquatic organisms. The paper presents data from a recent study which aims to assess the extent of contamination of the Gulf of Trieste after the closure of the Hg mine. Mercury and methylmercury were measured in various environmental compartments (estuarine and marine waters, sediments, and organisms) during the period 1995-1997. Data obtained show that even 10 years after closure of the Hg mine, Hg concentrations in river sediments and water are still very high and did not show the expected decrease of Hg in the Gulf of Trieste. A provisional annual mercury mass balance was established for the Gulf of Trieste showing that the major source of inorganic mercury is still the River Soca (Isonzo) while the major source of methylmercury is the bottom sediment of the Gulf.

    The Gulf of Mexico Research Initiative Information & Data Cooperative (GRIIDC) system is a data management solution appropriate for any researcher sharing Gulf of Mexico and oil spill science data. Our mission is to ensure a data and information legacy that promotes continual scientific discovery and public awareness of the Gulf of Mexico ecosystem. GRIIDC developed an open-source software solution to manage data from the Gulf of Mexico Research Initiative (GoMRI). The GoMRI program has over 2500 researchers from diverse fields of study with a variety of attitudes, experiences, and capacities for data sharing. The success of this solution is apparent through new partnerships to share data generated by RESTORE Act Centers of Excellence Programs, the National Academies of Science, and others. The GRIIDC data management system integrates dataset management planning, metadata creation, persistent identification, and data discoverability into an easy-to-use web application. No specialized software or program installations are required to support dataset submission or discovery. Furthermore, no data transformations are needed to submit data to GRIIDC; common file formats such as Excel, csv, and text are all acceptable for submissions. To ensure data are properly documented using the GRIIDC implementation of the ISO 19115-2 metadata standard, researchers submit detailed descriptive information through a series of interactive forms and no knowledge of metadata or xml formats are required. Once a dataset is documented and submitted the GRIIDC team performs a review of the dataset package. This review ensures that files can be opened and contain data, and that data are completely and accurately described. This review does not include performing quality assurance or control of data points, as GRIIDC expects scientists to perform these steps during the course of their work. Once approved, data are made public and searchable through the GRIIDC data discovery portal and the Data

    2011-03-01

    Full Text Available Abstract Background Nepal is one of the largest suppliers of labour to countries where there is a demand for cheap and low skilled workers. In the recent years the Gulf countries have collectively become the main destinations for international migration. This paper aims to explore the health problems and accidents experienced by a sample of Nepalese migrant in three Gulf countries. Methods A cross-sectional survey was conducted among 408 Nepalese migrants who had at least one period of work experience of at least six months in any of three Gulf countries: Qatar, Saudi Arabia and United Arab Emirates (UAE. Face to face questionnaire interviews were conducted applying a convenience technique to select the study participants. Results Nepalese migrants in these Gulf countries were generally young men between 26-35 years of age. Unskilled construction jobs including labourer, scaffolder, plumber and carpenter were the most common jobs. Health problems were widespread and one quarter of study participants reported experiencing injuries or accidents at work within the last 12 months. The rates of health problems and accidents reported were very similar in the three countries. Only one third of the respondents were provided with insurance for health services by their employer. Lack of leave for illness, cost and fear of losing their job were the barriers to accessing health care services. The study found that construction and agricultural workers were more likely to experience accidents at their workplace and health problems than other workers. Conclusion The findings suggest important messages for the migration policy makers in Nepal. There is a lack of adequate information for the migrants making them aware of their health risks and rights in relation to health services in the destination countries and we suggest that the government of Nepal should be responsible for providing this information. Employers should provide orientation on possible health

  6. Mass coral bleaching in the northern Persian Gulf, 2012

    Directory of Open Access Journals (Sweden)

    Javid Kavousi

    2014-09-01

    Full Text Available Coral bleaching events due to elevated temperatures are increasing in both frequency and magnitude worldwide. Mass bleaching was recorded at five sites in the northern Persian Gulf during August and September 2012. Based on available seawater temperature data from field, satellite and previous studies, we suggest that the coral bleaching threshold temperature in the northern Persian Gulf is between 33.5 and 34°C, which is about 1.5 to 2.5°C lower than that in the southern part. To assess the bleaching effects, coral genera counted during 60-minute dives were categorized into four groups including healthy, slightly bleached ( 50% bleached tissue and fully bleached colonies. The anomalously high sea surface temperature resulted in massive coral bleaching (~84% coral colonies affected. Acropora spp. colonies, which are known as the most vulnerable corals to thermal stress, were less affected by the bleaching than massive corals, such as Porites, which are among the most thermo-tolerant corals. Turbid waters, suggested as coral refugia against global warming, did not protect corals in this study since most affected corals were found in the most turbid waters. The 2012 bleaching in the northern Persian Gulf was relatively strong from the viewpoint of coral bleaching severity. Long-term monitoring is needed to understand the actual consequences of the bleaching event on the coral reefs and communities.

    A Spring 2004 multibeam sonar survey defined the seafloor geomorphology of the southern part of Gulf of California and the intersection of the East Pacific Rise with the North American continent. Survey goals included mapping structural patterns formed during the rifting that opened the Gulf and identifying the spatial transition from continental rifting to seafloor spreading. Multibeam sonar imagery, augmented with archival data and a subaerial DEM of Mexico, illuminates the principal features of this boundary zone between obliquely diverging plates: (i) active and inactive oceanic risecrests within young oceanic basins that are rich in evidence for off-axis magmatic eruption and intrusion; (ii) transforms with pull-apart basins and transpressive ridges along shearing continental margins and within oceanic crust; (iii) orphaned blocks of continental crust detached from sheared and rifted continental margins; and (iv) young, still-extending continental margins dissected by submarine canyons that in many cases are deeply drowned river valleys. Many of the canyons are conduits for turbidity currents that feed deep-sea fans on oceanic and subsided continental crust, and channel sediment to spreading axes, thereby modifying the crustal accretion process. We present a series of detailed bathymetric and seafloor reflectivity maps of this MARGINS Rupturing Continental Lithosphere focus site illustrating geomorphologic features of the southern part of the Gulf, from Guaymas Basin to the Maria Magdalena Rise.

    During the 1991 Persian Gulf War, over 700 oil wells in Kuwait were set ablaze by the withdrawing Iraqi army with the apparent intent of hindering satellite reconnaissance and intelligence gathering activities by the coalition of forces repelling Iraq from occupied Kuwait. The oil fires that burned for an estimated 10 months, created a huge smoke plume whose spatial extent went at times beyond the Persian Gulf region, mobilized across the Saharan Desert reaching as far west as the North Atlantic Ocean. The Nimbus-7 TOMS Total Ozone Mapping Spectrometer, in operation from October 1978 to May 1993, measured the near UV radiances that in the mid-1990's became the input in the calculation of the well know Absorbing Aerosol Index that represented a major breakthrough in satellite-based aerosol remote sensing. Thus, unknowingly to the world, the N7-TOMS sensor was collecting in 1991 an unprecedented daily record of what can be considered the worst environmental catastrophe affecting the atmosphere since the beginning of the era of space-based remote sensing in the 1970's. An overview of the temporal and spatial extent of the synoptic scale 1991 Gulf War smoke plume as seen by the Nimbus-7 TOMS Absorbing Aerosol Index will be presented.

    Soundscapes in the Northern Gulf of Mexico are complex and represent a combination of anthropogenic noise (oil exploration and production, shipping, rig construction, etc.), bio-soundscapes (sound of marine mammals and fish), and geo-soundscapes (weather events, submarine landslides, distant earthquakes, natural gas seeps). We will discuss how Passive Acoustic Monitoring in the deep Gulf has been utilized during the past decade to study the soundscape variability on daily, monthly, and yearly timescales and what environmental information can be extracted from this variability. Isolation of bio-soundscapes, identification of their sources, and abundance estimates based on acoustic cues are used to track the recovery of marine mammal species after major ecological disasters, such as the recent 2010 oil spill. Association of acoustic activity of marine species with anthropogenic noise levels and other environmental variables can provide base data that can be used to build ecological models of habitat preferences for different marine species. Understanding how the variability of anthropogenic soundscapes correlates with marine species distributions is critically important for regional conservation and mitigation strategies. Such studies can also assist in forecasting the long-term ecosystem health status and ecosystem response to disturbances of different spatial and temporal extent, including slow variations associated with climate change. [This research was made possible in part by a grant from The Gulf of Mexico Research Initiative, and in part by funding provided by ONR and The Joint Industry Programme.

    Two-hundred and twenty seven satellite-tracked drifters were deployed in the Gulf of Maine (GoM) from 1988 to 2007, primarily during spring and summer. The archive of tracks includes over 100,000 kilometers logged thus far. Statistics such as transit times, mean velocities, response to wind events, and preferred pathways are compiled for various areas of the coastal GoM. We compare Lagrangian flow with Eulerian estimates from near-by moorings and evaluate drifter trajectories using Ekman theory and 3-D ocean circulation models. Results indicate that the Gulf of Maine Coastal Current is a strong and persistent feature centered on the 94 ± 23 meter isobath, but that particles: a) deviate from the seasonal-mean core fairly regularly, and are often re-entrained; b) follow a slower (9 cm/s), less-constrained path in the western portion off the coast of Maine relative to the eastern (16 cm/s) section; and c) can be affected by wind events and small scale baroclinic structures. Residence times calculated for each ½ degree grid cell throughout the GoM depict some regions (Eastern Maine and Western Nova Scotia) as being relatively steady, flow-through systems, while others (Penobscot, Great South Channel) have more variable, branching pathways. Travel times for drifters that are retained within the coastal current along the entire western side of the Gulf of Maine are typically less than two months (55 days).

  11. Egypt's first subsea completion: A Gulf of Suez case history

    1996-01-01

    A case history of the Gulf of Suez Petroleum Co.'s (Gupco) first subsea completion is provided. The first completion was for Well GS 373-2, a previously drilled and tested exploration well located in the south portion of the gulf of Suez. Subsea technology was used to economically justify development of this one-well marginal field, which was discovered in 1978. Traditional methods proved to be too costly for development, therefore application of a low-cost subsea tree was used to capture the resources. In the Gulf of Suez, many fields have been discovered but have not been developed because of low reserves. These marginal projects can have a profound impact on the revenue and shareholder value if an economic method is used to exploit these opportunities. Platform installation was not feasible because of reserve size, hence the well has remained abandoned until recently. This paper presents a summarized look at subsea completion technology. The cost comparison of traditional development methods will be made, given the local cost structure in Egypt. The application of this technology has some limitations and constraints that will be discussed in the paper. Furthermore, the actual field installation of Egypt's first subsea tree will be summarized. Also included is a discussion on simple remote controls and offshore installation operations

  12. Environmental permits in Arab Gulf countries - local government perspective

    2002-01-01

    The legacy of past environmentally careless oil and gas exploration practices is becoming more apparent as time goes by and our understanding of causes and results increase. In many petroleum producing countries and in Arab Gulf countries in particular, this understanding has resulted in greater social demand for environmental protection and responsible exploitation of limited resources. In response to this demand, governments of the Gulf Region are paying increasingly more attention to the responsible management of environmental impacts of new developments. As a result, most of them require developers to obtain environmental permits supported by a variety of environmental baseline studies, Environmental Impact Assessments and comprehensive Environmental Management Plans. These local environmental requirements are similar to those in North America and Europe, although there are some important differences on account of local environmental, historical and socioeconomic conditions. Developers, who choose to ignore them, often find their projects caught in a web of unfamiliar environmental regulations or administrative procedures that may cause costly and unnecessary delays. Based on the author's Canadian and Arab Gulf regulatory experience, this paper describes some common causes that may delay obtaining environmental permits or cause cancellation of a project, and provides ideas to assist companies in securing necessary permits and licenses.

    The dynamics of hydrogen peroxide (H(2)O(2)) was investigated from December 2007 to October 2008 in the Gulf of Aqaba, which in the absence of H(2)O(2) contribution from biological production, rain and runoff, turned out to be a unique natural photochemical laboratory. A distinct seasonal pattern emerged, with highest midday surface H(2)O(2) concentrations in spring-summer (30-90 nM) as compared to winter (10-30 nM). Similarly, irradiation normalized net H(2)O(2) formation rates obtained in concurrent ship-board experiments were faster in spring-summer than in winter. These seasonal patterns were attributed to changes in water characteristics, namely elevated spring-summer chromophoric dissolved organic matter (CDOM). The role of trace elements in H(2)O(2) photoformation was studied by simultaneously measuring superoxide (O(2)(-)), Fe(II), and H(2)O(2) formation and loss in ambient seawater and in the presence of superoxide dismutase, iron and copper. O(2)(-) was found to decay fast in the Gulf water, with a half-life of 15-28 s, primarily due to catalytic reactions with trace metals (predominantly copper). Hence, H(2)O(2) formation in the Gulf involves metal-catalyzed O(2)(-) disproptionation. Added iron moderately lowered net H(2)O(2) photoformation, probably due to its participation in Fe(II) oxidation, a process that may also modify H(2)O(2) formation in situ.

  14. Risk and the social construction of 'Gulf War Syndrome'.

    2006-04-29

    Fifteen years since the events that are held by some to have caused it, Gulf War Syndrome continues to exercise the mind and energies of numerous researchers across the world, as well as those who purport to be its victims and their advocates in the media, law and politics. But it may be that the search for a scientific or medical solution to this issue was misguided in the first place, for Gulf War Syndrome, if there is such an entity, appears to have much in common with other 'illnesses of modernity', whose roots are more socially and culturally driven than what doctors would conventionally consider to be diseases. The reasons for this are complex, but derive from our contemporary proclivity to understand humanity as being frail and vulnerable in an age marked by an exaggerated perception of risk and a growing use of the 'politics of fear'. It is the breakdown of social solidarities across the twentieth century that has facilitated this process.Unfortunately, as this paper explores, our inability to understand the social origins of self-hood and illness, combined with a growing cynicism towards all sources of authority, whether political, scientific, medical or corporate, has produced a powerful demand for blame and retribution deriving from a resolute few who continue to oppose all of the evidence raised against them.Sadly, this analysis suggests that Gulf War Syndrome is likely to prove only one of numerous such instances that are likely to emerge over the coming years.

  18. A New Diagnostic Diagram of Ionization Sources for High-redshift Emission Line Galaxies

    Science.gov (United States)

    Zhang, Kai; Hao, Lei

    2018-04-01

    We propose a new diagram, the kinematics–excitation (KEx) diagram, which uses the [O III] λ5007/Hβ line ratio and the [O III] λ5007 emission line width (σ [O III]) to diagnose the ionization source and physical properties of active galactic nuclei (AGNs) and star-forming galaxies (SFGs). The KEx diagram is a suitable tool to classify emission line galaxies at intermediate redshift because it uses only the [O III] λ5007 and Hβ emission lines. We use the main galaxy sample of SDSS DR7 and the Baldwin‑Phillips‑Terlevich (BPT) diagnostic to calibrate the diagram at low redshift. The diagram can be divided into three regions: the KEx-AGN region, which consists mainly of pure AGNs, the KEx-composite region, which is dominated by composite galaxies, and the KEx-SFG region, which contains mostly SFGs. LINERs strongly overlap with the composite and AGN regions. AGNs are separated from SFGs in this diagram mainly because they preferentially reside in luminous and massive galaxies and have higher [O III]/Hβ than SFGs. The separation between AGNs and SFGs is even cleaner thanks to the additional 0.15/0.12 dex offset in σ [O III] at fixed luminosity/stellar mass. We apply the KEx diagram to 7866 galaxies at 0.3 Survey, and compare it to an independent X-ray classification scheme using Chandra observations. X-ray AGNs are mostly located in the KEx-AGN region, while X-ray SFGs are mostly located in the KEx-SFG region. Almost all Type 1 AGNs lie in the KEx-AGN region. These tests support the reliability of this classification diagram for emission line galaxies at intermediate redshift. At z ∼ 2, the demarcation line between SFGs and AGNs is shifted by ∼0.3 dex toward higher values of σ [O III] due to evolution effects.

  19. Hydrocarbon distributions in sediments of the open area of the Arabian Gulf following the 1991 Gulf War oil spill

    Surface sediments collected from the open area of the Arabian Gulf were analysed for total petroleum hydrocarbons and specific aliphatic hydrocarbon components in order to provide information on the extent of oil contamination and the degree of weathering of the spilled oil following the Gulf War. The surface distribution of the petroleum hydrocarbons showed an increasing trend towards the north-east, and among the individual transects there was a pronounced increasing trend towards the north-west direction. Despite off-shore oil-related activities as well as a potential impact from the 1991 oil spill, the concentrations of petroleum hydrocarbons in the study area were relatively low. This finding may be attributed to the effectiveness of weathering processes. (author)

  2. From continental to oceanic rifting in the Gulf of California

    Science.gov (United States)

    Ferrari, Luca; Bonini, Marco; Martín, Arturo

    2017-11-01

    The continental margin of northwestern Mexico is the youngest example of the transition from a convergent plate boundary to an oblique divergent margin that formed the Gulf of California rift. Subduction of the Farallon oceanic plate during the Cenozoic progressively brought the East Pacific Rise (EPR) toward the North America trench. In this process increasingly younger and buoyant oceanic lithosphere entered the subduction zone until subduction ended just before most of the EPR could collide with the North America continental lithosphere. The EPR segments bounding the unsubducted parts of the Farallón plate remnants (Guadalupe and Magdalena microplates) also ceased spreading (Lonsdale, 1991) and a belt of the North American plate (California and Baja California Peninsula) became coupled with the Pacific Plate and started moving northwestward forming the modern Gulf of California oblique rift (Nicholson et al., 1994; Bohannon and Parsons, 1995). The timing of the change from plate convergence to oblique divergence off western Mexico has been constrained at the middle Miocene (15-12.5 Ma) by ocean floor morphology and magnetic anomalies as well as plate tectonic reconstructions (Atwater and Severinghaus, 1989; Stock and Hodges, 1989; Lonsdale, 1991), although the onset of transtensional deformation and the amount of right lateral displacement within the Gulf region are still being studied (Oskin et al., 2001; Fletcher et al., 2007; Bennett and Oskin, 2014). Other aspects of the formation of the Gulf of California remain not well understood. At present the Gulf of California straddles the transition from continental transtension in the north to oceanic spreading in the south. Seismic reflection-refraction data indicate asymmetric continent-ocean transition across conjugate margins of rift segments (González-Fernández et al., 2005; Lizarralde et al., 2007; Miller and Lizarralde, 2013; Martín-Barajas et al., 2013). The asymmetry may be related to crustal

    2017-12-01

    The Gulf of Mexico is shared by the United States, Mexico and Cuba and requires collaborative work for integrated management to conserve its natural assets and derived benefits, as well as to foster the overall regional economic wealth. Many rivers drain into the Gulf, most notably the Mississippi, which ranks among global rivers 4th in discharge, 7th in sediment load and 3rd in drainage area, and accounts for about 90 percent of the freshwater inflow to the Gulf. The Mississippi River proper empties onto a narrow ( 20 km wide) continental shelf, and its tributary, the Atchafalaya River, that carries about one third of the total flow discharges onto the broad ( 200 km) and shallow part of the shelf. The entrainment of the Mississippi River discharge into the Louisiana Coastal Current results in the semblance of an extended estuary across much of the inner to mid continental shelf for much of the year. The nitrogen load from the Mississippi River to the adjacent continental shelf over the last half century has increased by 300 per cent. As a result, eutrophication and hypoxia have developed in this stratified coastal system with implications for biogeochemical cycles and valued resources. While there is recognition that over half of the nitrogen sources come from agricultural practices widespread across the watershed, the environmental goal of bringing a 32-year average 13,800 square kilometers of bottom-water hypoxia to less than 5,000 square kilometers is being realized through voluntary and incentive-based activities, designed within a series of subbasin and state strategies. Some activities funded by the US Department of Agriculture for directed nutrient reduction projects and several small-scale voluntary actions towards sustainable and ecologically sound agriculture show promise, but large-scale social-political solutions do not exist now nor will they for the forseeable future. The coastal waters adjacent to the Mississippi River are just one of many such

    2005-10-01

    We here summarize the evolution of the greater Red Sea-Gulf of Aden rift system, which includes the Gulfs of Suez and Aqaba, the Red Sea and Gulf of Aden marine basins and their continental margins, and the Afar region. Plume related basaltic trap volcanism began in Ethiopia, NE Sudan (Derudeb), and SW Yemen at ˜31 Ma, followed by rhyolitic volcanism at ˜30 Ma. Volcanism thereafter spread northward to Harrats Sirat, Hadan, Ishara-Khirsat, and Ar Rahat in western Saudi Arabia. This early magmatism occurred without significant extension, and continued to ˜25 Ma. Much of the Red Sea and Gulf of Aden region was at or near sea level at this time. Starting between ˜29.9 and 28.7 Ma, marine syn-tectonic sediments were deposited on continental crust in the central Gulf of Aden. At the same time the Horn of Africa became emergent. By ˜27.5-23.8 Ma a small rift basin was forming in the Eritrean Red Sea. At approximately the same time (˜25 Ma), extension and rifting commenced within Afar itself. At ˜24 Ma, a new phase of volcanism, principally basaltic dikes but also layered gabbro and granophyre bodies, appeared nearly synchronously throughout the entire Red Sea, from Afar and Yemen to northern Egypt. This second phase of magmatism was accompanied in the Red Sea by strong rift-normal extension and deposition of syn-tectonic sediments, mostly of marine and marginal marine affinity. Sedimentary facies were laterally heterogeneous, being comprised of inter-fingering siliciclastics, evaporite, and carbonate. Throughout the Red Sea, the principal phase of rift shoulder uplift and rapid syn-rift subsidence followed shortly thereafter at ˜20 Ma. Water depths increased dramatically and sedimentation changed to predominantly Globigerina-rich marl and deepwater limestone. Within a few million years of its initiation in the mid-Oligocene the Gulf of Aden continental rift linked the Owen fracture zone (oceanic crust) with the Afar plume. The principal driving force for extension

    The Nasca Lines are located in the Pampa region of Peru, the desolate plain of the Peruvian coast 400 km south of Lima. The Lines were first spotted when commercial airlines began flying across the Peruvian desert in the 1920's. Passengers reported seeing 'primitive landing strips' on the ground below. The Lines were made by removing the iron-oxide coated pebbles which cover the surface of the desert. When the gravel is removed, they contrast with the light color underneath. In this way the lines were drawn as furrows of a lighter color. On the pampa, south of the Nasca Lines, archaeologists have now uncovered the lost city of the line-builders, Cahuachi. It was built nearly two thousand years ago and was mysteriously abandoned 500 years later. This ASTER sub-image covers an area of 14 x 18 km, was acquired on December 22, 2000, and is located at 14.7 degrees south latitude and 75.1 degrees west longitude. The U.S. science team is located at NASA's Jet Propulsion Laboratory, Pasadena, Calif. The Terra mission is part of NASA's Science Mission Directorate.
