    Full Text Available Background: Pigmentary demarcation lines (PDL are physiological abrupt transition lines between hyperpigmented skin and lighter areas. Recent evidence suggests that they involve the face. Aims: To survey facial PDL in Saudi females referred to general dermatology clinics for various complaints and determine any associated risks. Methods: Screening for facial lines was done in general dermatology clinics over a year. Whenever a patient was found to have facial PDL, a detailed questionnaire and examination were undertaken. Results: Out of 1033 patients screened, 144 patients (14% were found to have at least one of the facial PDLs. The median age of onset was 16 years. The most common line was F with 76 patients (53%. Family history was positive in 51 patients (35%. Conclusion: Facial PDL is a common and chronic pigmentary problem in Saudi women. It should be recognized and differentiated from other similar diseases like melasma. A significant proportion of patients have a milder presentation.

    Full Text Available Background: To date, periorbital melanosis is an ill-defined entity. The condition has been stated to be darkening of the skin around the eyes, dark circles, infraorbital darkening and so on. Aims: This study was aimed at exploring the nature of pigmentation in periorbital melanosis. Methods: One hundred consecutive patients of periorbital melanosis were examined and investigated to define periorbital melanosis. Extent of periorbital melanosis was determined by clinical examination. Wood′s lamp examination was performed in all the patients to determine the depth of pigmentation. A 2-mm punch biopsy was carried out in 17 of 100 patients. Results: In 92 (92% patients periorbital melanosis was an extension of pigmentary demarcation line over the face (PDL-F. Conclusion: Periorbital melanosis and pigmentary demarcation line of the face are not two different conditions; rather they are two different manifestations of the same disease.

    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.

  9. Remote sensing and GIS analysis for demarcation of coastal hazard line along the highly eroding Krishna-Godavari delta front

    2016-10-01

    Coastal regions, especially river deltas are highly resourceful and hence densely populated; but these extremely low-lying lands are vulnerable to rising sea levels due to global warming threatening the life and property in these regions. Recent IPCC (2013) predictions of 26-82cm global sea level rise are now considered conservative as subsequent investigations such as by Met Office, UK indicated a vertical rise of about 190cm, which would displace 10% of the world's population living within 10 meters above the sea level. Therefore, predictive models showing the hazard line are necessary for efficient coastal zone management. Remote sensing and GIS technologies form the mainstay of such predictive models on coastal retreat and inundation to future sea-level rise. This study is an attempt to estimate the varying trends along the Krishna-Godavari (K-G) delta region. Detailed maps showing various coastal landforms in the K-G delta region were prepared using the IRS-P6 LISS 3 images. The rate of shoreline shift during a 31-year period along different sectors of the 330km long K-G delta coast was estimated using Landsat-2 and IRS-P6 LISS 3 images between 1977 and 2008. With reference to a selected baseline from along an inland position, End Point Rate (EPR), Shoreline Change Envelope (SCE) and Net Shoreline Movement (NSM) were calculated, using a GIS-based Digital Shoreline Analysis System (DSAS). The results showed that the shoreline migrated landward up to a maximum distance of 3.13km resulting in a net loss of about 42.10km2 area during this 31-year period. Further, considering the nature of landforms and EPR, the future hazard line is predicted for the area, which also indicated a net erosion of about 57.68km2 along the K-G delta coast by 2050 AD.

    Identifying a precise demarcation line (DL) is indispensable for pathological complete en bloc endoscopic submucosal dissection (ESD) for early gastric cancer (EGC). We evaluated the useful condition of chromoendoscopy with indigo carmine and acetic acid for marking dots around lesions before ESD for EGC. We examined 98 consecutive patients with 109 intramucosal EGCs (mean diameter, 17.8 ± 12.4 mm; main histologic type, 96 intestinal and 13 diffuse) resected by en bloc ESD after chromoendoscopy with indigo carmine and acetic acid between December 2012 and February 2014. The DL was identified by this technique just before ESD (mean chromoendoscopy observation time, 71.6 s); subsequently, marking dots were placed around the EGC. EGCs were classified into two groups: useful for identifying the DL or useless. Clinicopathological characteristics and clinical outcomes were evaluated in each group. Forty-two of the 109 cases (38.5 %) were determined useful for chromoendoscopy with indigo carmine and acetic acid. Multivariate analysis with logistic regression showed that macroscopic type (protruded or flat elevated-type) and atrophic border (the oral side of tumor) were independently associated with the usefulness of chromoendoscopy using indigo carmine and acetic acid for identifying the DL of EGCs (P acetic acid can be used for creating precise markings in protruded or flat elevated-type EGC or at the atrophic border on the oral side of EGCs.

    Clupeiform fish species, including the Gulf menhaden (Brevoortia patronus) that belong to the subfamily Alosinae, can detect ultrasound. Clupeiform fishes are unique in that they have specialized gas-filled bullae in the head associated with the ear via the bulla membrane and with the lateral line...... via the lateral recess membrane. It has been hypothesized that the utricle of the inner ear is responsible for ultrasound detection through a specialized connection to the gas-filled bullae complex. Here, we show that the lateral line and its connection to the gas-filled bullae complex via the lateral...... recess are involved in ultrasound detection in Gulf menhaden. Removal of a small portion of the lateral line overlying the lateral recess membrane eliminates the ability of Gulf menhaden to detect ultrasound. We further show that the gas-filled bullae vibrates in response to ultrasound, that the gas...

    The present investigation concerns the application of the Article 8-2 of the Mediterranean ICZM protocol in the environmentally sensitive coastal dune field of the central part of the Kyparissiakos Gulf (Ionian Sea, Greece). The Kyparissiakos dune field, comprising a set of coastal ecosystems of exceptional value, needs effective ICZM and, amongst all, has to consider the issue of Sea-Level Rise (SLR). The dune field consists of "parabolic" type dunes that are stable and subjected locally to human interference. It consists of four shore-parallel dune lines: the outer (and most recently formed) 1st dune line has formed during the last 500 years, the 2nd during the last 1000 years, whilst the 3rd and 4th lines have formed not later than 1600 years BP (Poulos et al., 2012). Moreover, the four dune lines (from the youngest to the oldest) lie at distances of approximately 60 m, 100 m, 200 m and 600 m from the coastline, having maximum heights of 4 m, 6 m, 10 m, and 10-12 m, respectively. The dune field, in general, is in equilibrium with the current nearshore hydrodynamics as the width of the beach zone is greater than the maximum run-up length (not included storm surge). The maximum wave run-up height (R), relative to the mean sea level, has been calculated by applying Komar's (1998) equation: R = 0.36 ṡ g0.5 ṡ S ṡ Ho0.5 ṡ T (g: acceleration of gravity; Ho: maximum offshore wave height; T: corresponding maximum wave period; S: tangential beach slope). Thus, the wave run-up due to the highest incoming waves can reach elevations of the order of 1.6m in the case of the NW waves (Ho=6m, T=9 s) and 2m in the case of W and SW waves (Ho=6.4m, T=6.4s). These elevations correspond to 25m and 40 m of tangential distances on the beach surface, which are less than the current beach width (> 60 m). However, if the maximum wave heights coincide with the maximum storm surge (0.5 m) observed in the area, wave action can reach and erode the foot of the 1st dune line. Thus, for

    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.

    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

  3. Significance of density and demarcation of calcifications in calcifying tendinitis

    Energy Technology Data Exchange (ETDEWEB)

    Uhthoff, H.K.; Sarkar, K.; Hammond, I.

    1982-04-01

    Calcification of tendons can be either degenerative and progressive in nature or reactive and selfhealing. Radiologic examinations permit to distinguish between both kinds. The reactive calcification, known also as calcifying tendinitis, passes through two main phases, the formative and the resorptive phase. Since treatment is different for each phase, their roentgenologic distinction is important. Dense, well demarcated and homogenous calcifications indicate the presence of a formative phase whereas less dense, ill defined and fluffy deposits point toward an ongoing resorption.

    In 1962, anthropologist Carleton Coon argued in The Origin of Races that some human races had evolved further than others. Among his most vocal critics were geneticist Theodosius Dobzhansky and anthropologist Ashley Montagu, each of whom had known Coon for decades. I use this episode, and the long relationships between scientists that preceded it, to argue that scientific research on race was intertwined not only with political projects to conserve or reform race relations, but also with the relationships scientists shared as colleagues. Demarcation between science and pseudoscience, between legitimate research and scientific racism, involved emotional as well as intellectual labor.

    Full Text Available Through the analysis of the new Brazilian Forest Code (Law 4,771/65 legislative reform, this paper shows the evolution of legal protection to the riparian system (marginal strips, defined as vegetation strings along rivers and other water bodies, which vary according to the water body width. The demarcation of permanent preservation areas along rivers is a complex process which has led to doubts and conflicts. Riparian systems are spaces aimed at the agricultural expansion and, thus, they’re under pressure. The analysis showed that the limitation posed by the new rule agrees with the principle of reasonableness. The new Brazilian Forest Code review, which is currently included in the National Congress agenda, will be able to positively contribute to achieve the possible and desired balance between respect to the natural environment and expansion of land uses.

    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

  7. Demarcation of Seabuckthorn Plantations in Three Northern Areas of China

    Institute of Scientific and Technical Information of China (English)

    2005-01-01

    Seabuckthorn (Hippophae rhamnoides) planting areas in the three northern areas (north, northeast and northwest) of China are divided into five planting zones: the semi-humid forest prairie climate zone for ecological and economic types of seabuckthorn plantations in the southern part of the Loess Plateau; the semi-arid steppe climate zone for similar types of plantations in the central part of the Loess Plateau; the arid desert steppe climate zone for ecological type of seabuckthorn plantations in the northern part of the Loess Plateau; the semi-arid and semi-humid steppe climate zone again for ecological and economic types of plantations in northern Hebei and western Liaoning and the cold humid steppe climate zone for economic types of plantations in the northern part of northeast China. The aim of this demarcation is to avoid a random introduction of seabuckthorn. In each of the five zones,objectives should be set and suitable seabuckthorn species, subspecies and varieties should be planted according to site conditions,seed sources and methods of tree breeding. The cultivation centers, bases, stations, or units should be established and successful models of seedling and planting methods should be encouraged. The principle of matching trees with suitable site conditions and adjusting measures to local conditions should be practiced. From a strategic viewpoint of solving ecological and economic problems of seabuckthorn development in the three northern areas, every seabuckthorn center must have its own germplasm nursery, standard plantation for popularizing, excellent seed and seedling nurseries and sufficient afforestation areas for demonstration and propaganda purposes. These measures would improve the ecological environment and promote economic and social development in the three northern areas of China.

    Several satellite-based methods have been used to detect and trace Karenia brevis red tide blooms in the eastern Gulf of Mexico. Some require data statistics and multiple data products while others use a single data product. Of these, the MODIS normalized fluorescence line height (nFLH) has shown its advantage of detecting blooms in waters rich in colored dissolved organic matter, thus having been used routinely to assess bloom conditions by the Florida Fish and Wildlife Conservation Commission (FWC), the official state agency of Florida responsible for red tide monitoring and mitigation. However, elevated sediment concentrations in the water column due to wind storms can also result in high nFLH values, leading to false-positive bloom interpretation. Here, a modified nFLH data product is developed to minimize such impacts through empirical adjustments of the nFLH values using MODIS-derived remote sensing reflectance in the green band at 547 nm. The new product is termed as an algal bloom index (ABI), which has shown improved performance over the original nFLH in both retrospective evaluation statistics and near real-time applications. The ABI product has been made available in near real-time through a Web portal and has been used by the FWC on a routine basis to guide field sampling efforts and prepare for red tide bulletins distributed to many user groups.

    Full Text Available Background: Seaweeds have proven to be a promising natural source of bioactive metabolites for drug development. Objective: This study aimed to monitor the ethanol extract of ten algae from the Persian Gulf and Oman Sea, for their in vitro cytotoxic activity on three human breast cancer cell lines. Materials and Methods: Three human breast cancer cell lines including MDA-MB-231(ER− , MCF-7(ER + , and T-47D (ER + were treated by different concentrations of total ethanol (90% algae extracts and the cytotoxic effects were evaluated by 3-(4,5-dimethylthiazol-2-yl-2,5-diphenyltetrazolium bromide assay. Doxorubicin (Ebewe, Austria was used as a positive control. After 72 h of incubation, the cytotoxic effect of the algae was calculated and presented as 50%-inhibitory concentration (IC 50 . Results: The results indicated Gracilaria foliifera and Cladophoropsis sp. to be the most active algae in terms of cytotoxic effects on the investigated cancer cell lines. The IC 50 values against MDA-MB-231, MCF-7, and T-47D cells were, respectively, 74.89 ± 21.71, 207.81 ± 12.07, and 203.25 ± 30.98 mg/ml for G. foliifera and 66.48 ± 4.96, 150.86 ± 51.56 and >400 mg/ml for Cladophoropsis sp. The rest of the algal extracts were observed not to have significant cytotoxic effects in the concentration range from 6.25 mg/ml to 400 mg/ml. Conclusion: Our data conclusively suggest that G. foliifera and Cladophoropsis sp. may be good candidates for further fractionation to obtain novel anticancer substances. Moreover, stronger cytotoxic effects on estrogen negative breast cancer cell line (MDA-MB-231(ER− in comparison to estrogen positive cells (MCF-7 and T-47D suggest that the extract of G. foliifera and Cladophoropsis sp. may have an estrogen receptor/progesterone receptor-independent mechanism for their cellular growth inhibition.

    This study aimed to evaluate the utility of optical enhancement (OE) in early gastric cancer demarcation. Twenty lesions of early gastric cancer were examined by PENTAX endoscopy system with OE-1 and OE-2 functions. The areas of tumor demarcation identified by 12 evaluators (6 novice and 6 experienced) were compared to the corresponding correct areas determined by postoperative histopathology findings. The misdiagnosed scores that were the sums of false-positive and false-negative areas were compared. Color of one hundred pixels from the inside of the cancerous area and the outside of the cancerous area was expressed as three-dimensional RGB component vectors. The mean vectors and covariance matrixes were calculated and the Mahalanobis distance, indicative of color differences between two areas, was tested. Comparisons of the misdiagnosed score revealed that OE-1 was preferred over WL-1 for gastric cancer demarcation for all 12 evaluators (p = 0.008) and in novice evaluators (p = 0.026). OE-2 was not significantly different from WL-2 in all cases. OE-1 images gave significantly larger Mahalanobis distances, indicative of color differences, than WL-1 images (p = 0.002). It was demonstrated that the OE Mode 1 has a significant advantage over the white light mode in demarcation of early gastric cancer.

    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.

    Method for robust demarcation of the basal cell carcinoma (BCC) is presented employing novel dependent component analysis (DCA)-based approach to unsupervised segmentation of the red-green-blue (RGB) fluorescent image of the BCC. It exploits spectral diversity between the BCC and the surrounding tissue. DCA represents an extension of the independent component analysis (ICA) and is necessary to account for statistical dependence induced by spectral similarity between the BCC and surrounding tissue. Robustness to intensity fluctuation is due to the scale invariance property of DCA algorithms. By comparative performance analysis with state-of-the-art image segmentation methods such as active contours (level set), K-means clustering, non-negative matrix factorization and ICA we experimentally demonstrate good performance of DCA-based BCC demarcation in demanding scenario where intensity of the fluorescent image has been varied almost two-orders of magnitude.

    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...

    Prime farmland (PF) is defined as high-quality farmland and a prime farmland protection area (PFPA, including related roads, waters and facilities) is a region designated for the special protection of PF. However, rapid urbanization in China has led to a tremendous farmland loss and to the degradation of farmland quality. Based on remote sensing and geographic information system technology, this study developed a semiautomatic procedure for designating PFPAs using high-resolution satellite imagery (HRSI), which involved object-based image analysis, farmland composite evaluation, and spatial analysis. It was found that the HRSIs can provide elaborate land-use information, and the PFPA demarcation showed strong correlation with the farmland area and patch distance. For the benefit of spatial planning and management, different demarcation rules should be applied for suburban and exurban areas around a metropolis. Finally, the overall accuracy of HRSI classification was about 80% for the study area, and high-quality farmlands from evaluation results were selected as PFs. About 95% of the PFs were demarcated within the PFPAs. The results of this study will be useful for PFPA planning and the methods outlined could help in the automatic designation of PFPAs from the perspective of the spatial science.

    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.

    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

    In this paper potential seismic sources in coastal region of South China are identified by integration of genetic algorithm (GA) and back propagation (BP algorithm). GA is used for finding the best parameter combination rapidly in an infinite solution space for artificial neural networks (ANN). The results show that the distribution of potential seismic sources with different upper magnitude demarcated by this classifier is mostly satisfied the intrinsic relationship between seismic environment and earthquake occurrence, with less effect from subjective judgment of human being.

    BACKGROUND Skin cancer is the most common malignancy and can be treated in various ways. One treatment modality is Mohs micrographic surgery. Due to the increasing incidence of skin cancer in the last decades, there is a need for improvement of the Mohs technique to optimize its effectiveness. OBJECTIVE The aim of this study was to evaluate the use of dermoscopy to guide demarcation of Mohs micrographic surgery margins and ascertain whether this method can reduce operative time and, therefore, reduce surgical morbidity and cost. METHODS AND MATERIALS The sample comprised 44 patients who underwent Mohs micrographic surgery, allocated into two groups: the control group and the intervention group. In the latter, surgical margins were guided by dermoscopy. RESULTS There were no statistically significant differences between the two groups by chi-square analysis (p = 0.399). CONCLUSION Although outcomes were similar in the two groups, demonstrating that dermoscopy does not help in the demarcation of surgical margins for Mohs micrographic surgery, the study provides a practical proposal for improvement of the Mohs technique.

    Retinal tears after laser photocoagulation are a rare complication that occurs after intense laser. It is talked about among retina specialist occurring particularly at the end of a surgical case while applying endophotocoagulation; to the best our knowledge, there are no reports in the literature of a large retinal tear induced after attempted in-office demarcation laser photocoagulation (DLP) that simulated a giant retinal tear. DLP has been employed in the management of selected cases of macula sparring rhegmatogenous retinal detachment (RRD). Even though extension of the retinal detachment through the "laser barrier" is considered a failure of treatment, few complications have been described with the use of this less invasive retinal detachment repair technique. We describe a case of a high myopic woman who initially was treated with demarcation laser photocoagulation for an asymptomatic retinal detachment associated with a single horseshoe tear and a full thickness large retinal tear was created where the laser was placed. Intense laser photocoagulation resulted in abrupt laser induced retinal necrosis and rupture creating this large retinal break. Proper laser technique should reduce the risks associated with this procedure.

    Introduction Twelve sections of upper Paleozoic to early Tertiary rocks from the Demarcation Point quadrangle and the northern edge of the Table Mountain quadrangle are presented. These measured sections include the type sections for the Joe Creek Member of the Echooka Formation (Section 11), the Bathtub Graywacke and Kongakut Formation (Section 9), and the unnamed early Tertiary rocks (Section 1). The early Tertiary rocks correlate closely with the Moose Channel Formation in the MacKenzie Delta, Candada (Detterman and Spicer, 1981). The sections were measured with a Jacob's staff during the geologic investigations of the Demarcation Point quadrangle in 1969 to 1971. The geologic map is published in generalized form (Detterman, 1974, 1976; Detterman and others, 1975). The sections are at a scale of 1 in to 100 ft, except for section 1, which is at 1 in to 200 ft. The location map shows the year and station number for each station. Fossils collected from these rocks and marked by and asterisk (*) are included in Detterman and others, 1975 (p. 42-45). A double asterisk (**) indicates they are included in the list below. All other fossil indicators mean fossils are present, but not collected.

  7. Cosmology at the Crossroads of the Natural and Human Sciences: is demarcation possible?

    CERN Document Server

    Nesteruk, Alexei V

    2011-01-01

    The paper discusses the problem of demarcation between the dimensions of natural and the human sciences in contemporary cosmology. In spite of a common presumption that cosmology is a natural science, the specificity of its alleged subject matter, that is the universe as a whole, makes cosmology fundamentally different from other natural sciences. The reason is that in cosmology the subject of cosmological research and its "object" are in a certain sense inseparable. Any study of the universe involves two opposite perspectives which can be described as "a-cosmic" and "cosmic", egocentric and non-egocentric. Cosmology involves two languages, namely that of physical causality (pertaining to the natural sciences) and that of intentionality (pertaining to the human sciences). On the one hand the universe can be seen as a product of discursive reason, that is as an abstract "physical" entity unfolding in space and time. On the other hand the universe can be experienced through our participation in, or communion wi...

    Identification of closely related, ecologically distinct populations of bacteria would benefit microbiologists working in many fields including systematics, epidemiology and biotechnology. Several laboratories have recently developed algorithms aimed at demarcating such 'ecotypes'. We examine the ability of four of these algorithms to correctly identify ecotypes from sequence data. We tested the algorithms on synthetic sequences, with known history and habitat associations, generated under the stable ecotype model and on data from Bacillus strains isolated from Death Valley where previous work has confirmed the existence of multiple ecotypes. We found that one of the algorithms (ecotype simulation) performs significantly better than the others (AdaptML, GMYC, BAPS) in both instances. Unfortunately, it was also shown to be the least efficient of the four. While ecotype simulation is the most accurate, it is by a large margin the slowest of the algorithms tested. Attempts at improving its efficiency are underway.

    Donnelly, Lisa A.

    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

  14. Rings dominate western Gulf

    Vidal L., Francisco V.; Vidal L., Victor M. V.; Molero, José María Pérez

    Surface and deep circulation of the central and western Gulf of Mexico is controlled by interactions of rings of water pinched from the gulf's Loop Current. The discovery was made by Mexican oceanographers who are preparing a full-color, 8-volume oceanographic atlas of the gulf.Anticyclonic warm-core rings pinch off the Loop Current at a rate of about one to two per year, the scientists of the Grupo de Estudios Oceanográficos of the Instituto de Investigaciones Eléctricas (GEO-IIE) found. The rings migrate west until they collide with the continental shelf break of the western gulf, almost always between 22° and 23°N latitude. On their westward travel they transfer angular momentum and vorticity to the surrounding water, generating cyclonic circulations and vortex pairs that completely dominate the entire surface and deep circulation of the central and western gulf.

    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.

  16. 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.

    In this study the thermal degradation of gratings inscribed in three types of fiber namely, PS 1250/1500, SM 1500 and zero water peak single mode fiber is demonstrated. A comparative investigation is carried out on the aging characteristics of the gratings at three different temperature ramping rates of 3 °C/min, 6 °C/min and 9 °C/min. During the thermal annealing treatment, a significant enhancement in the grating reflectivity is observed for PS 1250/1500 fiber from ∼1.2 eV until 1.4 eV which indicates a thermal induced reversible effect. Higher temperature ramping rates lead to a higher regeneration temperature. In addition, the investigation also reflects that regardless of the temperature ramping rate the thermal decay behavior of a specific fiber can be successfully characterized when represented in a demarcation energy domain. Moreover, this technique can be accommodated when predicting the thermal decay characteristics of a specific fiber.

    Cardiac progenitor/stem cells in adult hearts represent an attractive therapeutic target for heart regeneration, though (inter)-relationships among reported cells remain obscure. Using single-cell qRT–PCR and clonal analyses, here we define four subpopulations of cardiac progenitor/stem cells in adult mouse myocardium all sharing stem cell antigen-1 (Sca1), based on side population (SP) phenotype, PECAM-1 (CD31) and platelet-derived growth factor receptor-α (PDGFRα) expression. SP status predicts clonogenicity and cardiogenic gene expression (Gata4/6, Hand2 and Tbx5/20), properties segregating more specifically to PDGFRα+ cells. Clonal progeny of single Sca1+ SP cells show cardiomyocyte, endothelial and smooth muscle lineage potential after cardiac grafting, augmenting cardiac function although durable engraftment is rare. PDGFRα− cells are characterized by Kdr/Flk1, Cdh5, CD31 and lack of clonogenicity. PDGFRα+/CD31− cells derive from cells formerly expressing Mesp1, Nkx2-5, Isl1, Gata5 and Wt1, distinct from PDGFRα−/CD31+ cells (Gata5 low; Flk1 and Tie2 high). Thus, PDGFRα demarcates the clonogenic cardiogenic Sca1+ stem/progenitor cell. PMID:25980517

  19. An analysis of the demarcation problem in science and its application to therapeutic touch theory.

    Newbold, David; Roberts, Julia

    2007-12-01

    This paper analyses the demarcation problem from the perspective of four philosophers: Popper, Kuhn, Lakatos and Feyerabend. To Popper, pseudoscience uses induction to generate theories, and only performs experiments to seek to verify them. To Popper, falsifiability is what determines the scientific status of a theory. Taking a historical approach, Kuhn observed that scientists did not follow Popper's rule, and might ignore falsifying data, unless overwhelming. To Kuhn, puzzle-solving within a paradigm is science. Lakatos attempted to resolve this debate, by suggesting history shows that science occurs in research programmes, competing according to how progressive they are. The leading idea of a programme could evolve, driven by its heuristic to make predictions that can be supported by evidence. Feyerabend claimed that Lakatos was selective in his examples, and the whole history of science shows there is no universal rule of scientific method, and imposing one on the scientific community impedes progress. These positions are used in turn, to examine the scientific status of therapeutic touch theory. The paper concludes that imposing a single rule of method can impede progress, in the face of multiple epistemologies, and the choice of scientific approach should be a pragmatic one based on the aims of the programme.

  20. [Physician assistance in dying or help to die--a line of legal demarcation (from the lawyer's perspective)].

    Ulsenheimer, Klaus

    2008-01-01

    The definition of the legal prerequisites for the permissible withholding/withdrawal of medical treatment, the limits to a physician's obligation to provide medical care as well as the differentiation between the aiding with suicide, which is exempt from punishment, and the punishable termination of life upon request or failure to render assistance is actually one of the most difficult medico-legal, professional-ethical, human, ideological and moral problems. The numerous views and opinions expressed are varying accordingly so that the call for legislative action comes as no surprise. Nonetheless, legal practice has provided clarity for a large number of aspects. The life of a human being scores the highest on the value scale of the Basic Law (GG) of the Federal Republic of Germany; the right to self-determination is of particular significance. It does not imply the "right to suicide", though, but suicide--and the participation in it--is not subject to punishment. But if the physician exercises control over the act ("Tatherrschaft") he is required to provide all necessary and reasonable life-saving assistance. There is general consent that assistance with dying by way of intentional killing (active direct euthanasia) is a crime whereas palliative treatment of the terminally ill while accepting the unintentional and inevitable side effect of hastening the patient's death is justified (so-called indirect euthanasia). The so-called passive euthanasia which is characterised by withholding/withdrawing treatment measures is associated with the most difficult problems. In this context the permissible ,,assistance in dying", i.e., the actual euthanasia, has to be distinguished from ,,help to die", that is, euthanasia in a broader sense, as the Federal Supreme Court (BGH) correctly pointed out in its leading decision (BGHSt 40, 257 et sqq.). Within this differentiation the advance directive is of particular importance since only subsidiary reference may be made to the ,,presumed will or consent" of the patient and, if this cannot be identified, to "general values" for the physician's decision-making. If the patient's will or the general values cannot be identified unambiguously, the protection of life must take priority with the patient's physician, his relatives or his guardian, unless there is no medical indication for the respective treatment procedure.

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

    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.

    Full Text Available BACKGROUND: Though the adult human magnocellular Red nucleus (mNr is essentially vestigial and its boundaries with neighbouring structures have never been well demarcated, human studies in utero have shown a well developed semilunar mNr wrapping around the caudal parvicellular Red nucleus (pNr, similar to what is seen in quadrupeds. In the present study, we have sought to better delineate the morphological determinants of the adult human Red nucleus (ahRn. METHODS AND FINDINGS: Serial sections of ahRn show fine myelinated fibers arising from pNr and turning toward the central tegmental tract. DiI was deposited within a well restricted region of ahRn at the fasciculus retroflexus level and the extent of label determined. Nissl-stained serial sections allowed production of a 3-D mNr model, showing rudimentary, vestigial morphology compared with its well developed infant homologue. DiI within this vestigial mNr region at the level of the oculomotor nerve showed labeled giant/large mNr neurons, coarse fiber bundles at the ventral tegmental decussation and lateral lemniscal label. CONCLUSIONS: Large amounts of DiI and a long incubation time have proven useful in aged human brain as a marker of long axons and large cell bodies of projecting neurons such as the rubrospinal projection and for clarifying nuclear boundaries of closed nuclei (e.g., the large human pNr. Our 3D model of adult human mNr appeared shrunken in shape and axially rotated compared with the infant mNr, the rotation being a common feature among mammalian mNr.

  5. Gulf stream separation dynamics

    Science.gov (United States)

    Schoonover, Joseph

    Climate models currently struggle with the more traditional, coarse ( O(100 km) ) representation of the ocean. In these coarse ocean simulations, western boundary currents are notoriously difficult to model accurately. The modeled Gulf Stream is typically seen exhibiting a mean pathway that is north of observations, and is linked to a warm sea-surface temperature bias in the Mid-Atlantic Bight. Although increased resolution ( O(10 km) ) improves the modeled Gulf Stream position, there is no clean recipe for obtaining the proper pathway. The 70 year history of literature on the Gulf Stream separation suggests that we have not reached a resolution on the dynamics that control the current's pathway just south of the Mid-Atlantic Bight. Without a concrete knowledge on the separation dynamics, we cannot provide a clean recipe for accurately modeling the Gulf Stream at increased resolutions. Further, any reliable parameterization that yields a realistic Gulf Stream path must express the proper physics of separation. The goal of this dissertation is to determine what controls the Gulf Stream separation. To do so, we examine the results of a model intercomparison study and a set of numerical regional terraforming experiments. It is argued that the separation is governed by local dynamics that are most sensitive to the steepening of the continental shelf, consistent with the topographic wave arrest hypothesis of Stern (1998). A linear extension of Stern's theory is provided, which illustrates that wave arrest is possible for a continuously stratified fluid.

    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

  9. The role of the Gulf Stream in European climate.

    2015-01-01

    The Gulf Stream carries the warm, poleward return flow of the wind-driven North Atlantic subtropical gyre and the Atlantic Meridional Overturning Circulation. This northward flow drives a significant meridional heat transport. Various lines of evidence suggest that Gulf Stream heat transport profoundly influences the climate of the entire Northern Hemisphere and, thus, Europe's climate on timescales of decades and longer. The Gulf Stream's influence is mediated through feedback processes between the ocean, atmosphere, and cryosphere. This review synthesizes paleoclimate archives, model simulations, and the instrumental record, which collectively suggest that decadal and longer-scale variability of the Gulf Stream's heat transport manifests in changes in European temperature, precipitation, and storminess. Given that anthropogenic climate change is projected to weaken the Atlantic Meridional Overturning Circulation, associated changes in European climate are expected. However, large uncertainty in the magnitude of the anticipated weakening undermines the predictability of the future climate in Europe.

  10. Gulf ring algae

    Although they rank among the tiniest of the microspcopic phytoplankton, coccolithophore algae aid oceanographers studying the Gulf Stream rings and the ring boundaries. The algal group could help to identify more precisely the boundary of the warm rings of water that spin off from the Gulf Stream and become independent pools of warm water in the colder waters along the northeastern U.S. coast.Coccolithophore populations in the Gulf Stream rings intrigue oceanographers for two reasons: The phytoplankton are subjected to an environment that changes every few days, and population explosions within one coccolithophore species seem to be associated with changes in the characteristics of ocean water, said Pat Blackwelder, an associate professor at the Nova Oceanographic Center in Dania, Fla. She is one of many studying the physics, chemistry, and biology of warm core rings. A special oceanography session on these rings was held at the recent AGU Fall Meeting/ASLO Winter Meeting.

  11. Between hope and evidence: how community advisors demarcate the boundary between legitimate and illegitimate stem cell treatments.

    Stem cell science provides an exemplary study of the 'management of hope'. On the one hand, raising 'hopes' and expectations is a seen as a necessary aspect of securing investment in promising innovative research. On the other, such hyperbole risks raising hopes to a level that may lead people to undertake undue risks, which may ultimately undermine confidence in medical research. In this context, the 'management of hope' thus involves the negotiation of competing claims of truth about the value and safety of particular treatments and about the trustworthiness of providers. Using Gieryn's concept of boundary-work, this article examines the means by which this work of 'managing hope' is undertaken. Drawing on data collected as part of our study that investigated the perspectives of those who are consulted by patients and their carers about stem cell treatments, we explore how these community advisors – both scientists and clinicians with a stake in stem cell research and representatives from patient advocacy groups – demarcate the boundary between legitimate and illegitimate treatments. In particular, we examine how these actors rhetorically use 'evidence' to achieve this demarcation. We argue that analysing accounts of how advisors respond to patient enquiries about stem cell treatments offers a window for examining the workings of the politics of hope within contemporary bioscience and biomedicine. In conclusion, we emphasize the need to re-conceptualize the boundary between science and non-science so as to allow a better appreciation of the realities of health care in the age of medical travel.

  12. Robust demarcation of basal cell carcinoma by dependent component analysis-based segmentation of multi-spectral fluorescence images.

    This study was designed to demonstrate robust performance of the novel dependent component analysis (DCA)-based approach to demarcation of the basal cell carcinoma (BCC) through unsupervised decomposition of the red-green-blue (RGB) fluorescent image of the BCC. Robustness to intensity fluctuation is due to the scale invariance property of DCA algorithms, which exploit spectral and spatial diversities between the BCC and the surrounding tissue. Used filtering-based DCA approach represents an extension of the independent component analysis (ICA) and is necessary in order to account for statistical dependence that is induced by spectral similarity between the BCC and surrounding tissue. This generates weak edges what represents a challenge for other segmentation methods as well. By comparative performance analysis with state-of-the-art image segmentation methods such as active contours (level set), K-means clustering, non-negative matrix factorization, ICA and ratio imaging we experimentally demonstrate good performance of DCA-based BCC demarcation in two demanding scenarios where intensity of the fluorescent image has been varied almost two orders of magnitude.

    2007-01-01

    Traditionally, the understanding of the demarcation between indemnity and compensation starts from Rechtswidrigkeit (illegality). However, with the rise of"Erfolgsunrecht theory" and the objective base of negligence, and with the convergence of the theoretic bases of compensation and indemnity, the demarcation between compensation and indemnity is vanishing. This phenomenon should have given rise to our retrospection on the traditional research on the methods of state indemnity, which, at the same time, would be of a big influence on the orientation of the amendments to our State Indemnity Law and how to adopt the legislation on administrative compensation. Hence, it is necessary to reconstruct the elements of state indemnity and administrative compensation.

    From hosting key shipping lines, drilling platforms, and commercial fisheries, to sustaining mangrove swamps that shelter the coastline from the hurricanes that churn its waters, the Gulf of Mexico is important to the nations surrounding it for socio-economic, ecological, military, political, and scientific reasons. Critical to all of these sectors is the Gulf's circulation—it controls hurricane tracks and intensity, biological productivity, and larvae dispersal. Since 1982, the Environmental Studies Program (ESP) of the U.S. Bureau of Ocean Energy Management, Regulation and Enforcement (BOEMRE) has invested more than $67 million in field and numerical modeling studies to improve our understanding of the Gulf's circulation (see Figure 1). ESP-funded research has covered a broad array of topics, some applied and some basic. Studies carried out on behalf of the bureau reflect the bureau's information needs, stakeholder input, and offshore energy exploration and development trends. All ESP studies culminate in a technical report—127 technical reports on physical oceanography are publicly available (see http://www.gomr.boemre.gov/homepg/regulate/environ/techsumm/rec_pubs.html). Additionally, more than 100 peer-reviewed publications have been issued on the Gulf's physical oceanography and circulation. The AGU Geophysical Monograph Circulation in the Gulf of Mexico: Observations and Models, the very first circulation overview since 1972, was funded by ESP. Additionally, data collected during fieldwork are deposited in national archives for public dissemination.

    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

  3. Punctuated distribution of recombination hotspots and demarcation of pericentromeric regions in Phaseolus vulgaris L.

    High density genetic maps are a reliable tool for genetic dissection of complex plant traits. Mapping resolution is often hampered by the variable crossover and non-crossover events occurring across the genome, with pericentromeric regions (pCENR) showing highly suppressed recombination rates. The efficiency of linkage mapping can further be improved by characterizing and understanding the distribution of recombinational activity along individual chromosomes. In order to evaluate the genome wide recombination rate in common beans (Phaseolus vulgaris L.) we developed a SNP-based linkage map using the genotype-by-sequencing approach with a 188 recombinant inbred line family generated from an inter gene pool cross (Andean x Mesoamerican). We identified 1,112 SNPs that were subsequently used to construct a robust linkage map with 11 groups, comprising 513 recombinationally unique marker loci spanning 943 cM (LOD 3.0). Comparative analysis showed that the linkage map spanned >95% of the physical map, indicating that the map is almost saturated. Evaluation of genome-wide recombination rate indicated that at least 45% of the genome is highly recombinationally suppressed, and allowed us to estimate locations of pCENRs. We observed an average recombination rate of 0.25 cM/Mb in pCENRs as compared to the rest of genome that showed 3.72 cM/Mb. However, several hot spots of recombination were also detected with recombination rates reaching as high as 34 cM/Mb. Hotspots were mostly found towards the end of chromosomes, which also happened to be gene-rich regions. Analyzing relationships between linkage and physical map indicated a punctuated distribution of recombinational hot spots across the genome.

    In order to achieve the overall progress of the country with active and effective participation of all sections of society, the 12th Five Year Plan (FYP) would bring Panchayats centre-stage and achieve the inclusive growth agenda through inclusive governance. The concept of 'democratic decentralization' in the form of a three-tier administration was introduced in the name of "Panchayat Raj". Horizontally, it is a network of village Panchayats. Vertically, it is an organic growth of Panchayats rising up to national level. The Ministry of Panchayati Raj has three broad agenda: Empowerment, Enablement and Accountability. Space based Information Support for Decentralized Planning (SIS-DP) is one of the initiatives taken by Govt. of India with ISRO/DOS for generation and dissemination of spatial information for planning at the grass root level. The boundary layer for villages across different states/district/block is available with line departments. Most of these data exist at a much generalized scale. These boundaries do not overlay exactly with that of ground realities and may not be suitable for accurate analysis in terms of area, shape, position, etc. To deal with this problem, a strategy is adopted, which makes use of High Resolution Satellite Imagery (HRSI) from Indian Remote sensing satellites and cadastral maps at 1:4000 scale integrated with GIS techniques to enhance the accuracy of geo-spatial depiction of Village/Panchayat boundaries. Cadastral maps are used to depict the boundaries of land parcels and other features at the village level. These maps are registered to ortho products of HRSI using Ground Control Points. The cadastral maps are precisely overlaid on ortho-rectified HRSI and each parcel vertex is tagged with the real-world geographical coordinates. Village boundaries are extracted from the geo-referenced village cadastral maps. These boundaries are fine-tuned by considering under lap and overlap of neighboring villages and a mosaic is generated at

  5. 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.

    The study of lexical meaning, an integral part of semantics, normally begins with demarcating lexical meaning, which is still a controversial and open issue today. Of the two widely accepted distinctive types of meaning, "sense" is the term which this paper attempts to elucidate. The paper also provides certain critical commentary on defining "sense" as "wholly internal to the language system" .%作为语义学的重要部分,对词义的研究通常以词义分类或区分开始。如何区分词义一直是一个有争论的、开放的议题。本文主要针对被普遍接受的sense与reference(或sense与denotation)的二项对立中的sense加以某些诠释并对sense“完全是语言内部的”这一界定进行了一定批评性思考。

  10. Deglacial climatic oscillations in the Gulf of California

    Science.gov (United States)

    Keigwin, L. D.; Jones, G. A.

    1990-12-01

    A high-resolution, accelerator radiocarbon dated climate record of the interval 8,000-18,000 years B.P. from Deep Sea Drilling Project site 480 (Guaymas Basin, Gulf of California) shows geochemical and lithological oscillations of oceanographic and climatic significance during deglaciation. Nonlaminated sediments are associated with cooler climatic conditions during the late glacial (up to 13,000 years B.P.), and from 10,300 to 10,800 years B.P., equivalent to the Younger Dryas event of the North Atlantic region. We propose that the changes from laminated (varved) to nonlaminated sediments resulted from increased oxygen content in Pacific intermediate waters during the glacial and the Younger Dryas episodes, and that the forcing for the latter event was global in scope. Prominent events of low δ18O are recorded in benthic foraminifera from 8,000 to 10,000 and at 12,000 years B.P.; evidence for an earlier event between 13,500 and 15,000 years B.P. is weaker. Maximum δ18O is found to have occurred 10,500, 13,500, and 15,000 years ago (and beyond). Oxygen isotopic variability most likely reflects changing temperature and salinity characteristics of Pacific waters of intermediate depth during deglaciation or environmental changes within the Gulf of California region. Several lines of evidence suggest that during deglaciation the climate of the American southwest was marked by increased precipitation that could have lowered salinity in the Gulf of California. Recent modelling studies show that cooling of the Gulf of Mexico due to glacial meltwater injection, which is believed to have occurred at least twice during deglaciation, would have resulted in increased precipitation with respect to evaporation in the American southwest during summertime. The timing of deglacial events in the Gulf of Mexico and the Gulf of California supports such an atmospheric teleconnection.

  15. 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.

    Whitney, Nina M.; Wanamaker, Alan D.; Kreutz, Karl J.; Introne, Douglas S.

    2017-04-01

    Hydrographic variability and dynamics in the Gulf of Maine are examined through the investigation of δ18Ow and salinity properties of coastal surface waters. Data from Gulf of Maine waters sampled over a decade, from 2003 to 2015, including a suite of samples that were collected monthly from April 2014 to March 2015, are presented. These water samples fall on a mixing line between Maine River Water (MRW) and Scotian Shelf Water (SSW). However, slope waters likely also contribute to these surface waters. The seasonal variability in water samples collected during 2014 and 2015 indicates the strong influence of river runoff on coastal Gulf of Maine surface water properties. The coastal Gulf of Maine mixing line presented in this paper is a needed baseline for reconstructing hydrographic variability in bicarbonates using oxygen isotopes.

    1977-01-01

    Experiment MA-060 was designed to establish the crystal growth and segregation characteristics of a melt in a directional solidification configuration under near zero-g conditions. The interface demarcation technique was incorporated into the experiment since it constitutes a unique tool for recording the morphology of the growth rate throughout solidification, and for establishing an absolute time reference framework for all stages of the solidification process. An extensive study was performed of the germanium crystals grown during the Apollo-Soyuz Test Project mission. It was found that single crystal growth was achieved and that the interface demarcation functioned successfully. There was no indication that convection driven by thermal or surface tension gradients was present in the melt. The gallium segregation, in the absence of gravity, was found to be fundamentally different in its initial and its subsequent stages from that of the ground-based tests. None of the existing theoretical models for growth and segregation can account for the observed segregation behavior in the absence of gravity.

    The crystal growth and segregation characteristics of a melt in a directional solidification configuration under near zero g conditions were investigated. The germanium (doped with gallium) system was selected because it was extensively studied on Earth and because it lends itself to a very detailed macroscopic and microscopic characterization. An extensive study was performed of the germanium crystals grown during the Apollo-Soyuz Test Project mission. It was found that single crystal growth was achieved and that the interface demarcation functioned successfully. On the basis of the results obtained to date, there is no indication that convection driven by thermal or surface tension gradients was present in the melt. The gallium segregation, in the absence of gravity, was found to be fundamentally different in its initial and its subsequent stages from that of the ground based tests. None of the existing theoretical models for growth and segregation can account for the observed segregation behavior in the absence of gravity.

    Science.gov (United States)

    2017-09-01

    On the 27 June 2015, at 15:34:03 UTC, a moderate-sized earthquake of M w 5.0 occurred in the Gulf of Aqaba. Using teleseismic P waves, the focal mechanism of the mainshock was investigated by two techniques. The first technique used the polarities of the first P wave onsets, and the second technique was based on the normalized waveform modeling technique. The results showed that the extension stress has a NE orientation with a shallow southward plunge while the compression stress has a NW trend with a nearly shallow westward plunge, obtaining a strike-slip mechanism. This result agrees well with the typical consequence of crustal deformation resulting from the ongoing extensional to shear stress regime in the Gulf of Aqaba (NE-SW extension and NW-SE compression). The grid search method over a range of focal depths indicates an optimum solution at 15 ± 1 km. To identify the causative fault plane, the aftershock hypocenters were relocated using the local waveform data and the double-difference technique. Considering the fault trends, the spatial distribution of relocated aftershocks demarcated a NS-oriented causative fault, in consistence with one of the nodal planes of the focal mechanism solution, emphasizing the dominant stress regime in the region. Following the Brune model, the estimates of source parameters exhibited fault lengths of 0.29 ≤ L ≤ 2.48 km, moment magnitudes of 3.0 ≤ M w ≤ 5.0, and stress drops of 0.14 ≤ Δ σ < 1.14 MPa, indicating a source scaling similar to the tectonic earthquakes related to plate boundaries.

    2012-01-01

    One of the largest oil spills in world history happened off the Alabama Gulf coast in April of 2010. One year later the Gulf Coast community was still trying to recover and reestablish itself as a major source for the shipping, tourism, fishing and energy industries. Although this disaster did not physically destroy communities and families, it did take an economic and psychological toll. Researchers conducted focus groups with mental health professionals employed by Project Rebound, a state sponsored response to disasters in Alabama to explore the mental health effects of the Gulf Oil Spill on two gulf coast communities one year after the spill. Project Rebound clinicians were the front line of the mental health response to the spill and collaborated with community service agencies to provide support to adults, children, and families in the Gulf Coast community. The semi-structured focus groups allowed staff to discuss the extent of mental health treatment utilization as well as provide valuable input as to what can be done to better prepare communities and agencies for future disasters.

    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).

    2015-02-01

    Supercritical fluids are widely used in a number of important technological applications, yet the theoretical progress in the field has been rather moderate. Fairly recently, a new understanding of the liquidlike and gaslike properties of supercritical fluids has come to the fore, particularly with the advent of the Widom and Frenkel lines that aim to demarcate different physical properties on the phase diagram. Here, we report the results of a computational study of supercritical carbon dioxide, one of the most important fluids in the chemical industry. We study the response functions of CO2 in the supercritical state and calculate the locations of their maxima (Widom lines). We also report the preliminary calculations of the Frenkel line, the line of crossover of microscopic dynamics of particles. Our insights are relevant to physical processes in the atmosphere of Venus and its evolution.

  20. Integrated approach for demarcating subsurface pollution and saline water intrusion zones in SIPCOT area: a case study from Cuddalore in Southern India.

    Sankaran, S; Sonkamble, S; Krishnakumar, K; Mondal, N C

    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.

  1. Lagrangian Coherent Structures in the Trieste Gulf

    Besio, G.; Enrile, F.; Magaldi, M. G.; Mantovani, C.; Cosoli, S.; Gerin, R.; Poulain, P. M.

    2013-12-01

    One serious issue in Environmental Science and Engineering concerns the prediction of the fate of contaminants released in a water body. A possible way to tackle this problem consists in forecasting pollutant trajectories from velocity-field data sets obtained by measurements or numerical simulations. A shortcoming of such a traditional approach is the high sensitivity to initial conditions. Another way to understand transport in complex fluid flows comes from a new mathematical tool: Lagrangian Coherent Structures (LCS). The idea of using Lagrangian Structures rose as a meeting point between non-linear dynamics and fluid mechanics. It provides the means to identify material lines that shape trajectory patterns, dividing the flow field into regions with different dynamical behaviours. The objective of this study is the detection of Lagrangian Coherent Structures in the Gulf of Trieste. LCS are calculated from the 2D surface velocity field measured by the coastal radars of the TOSCA (Tracking Oil Spills & Coastal Awareness network) project. Blobs of simulated particles are subjected to chaotic stirring (transport and stretching) that is in agreement with the detected LCS. In the TOSCA project drifters were deployed, too. Therefore, a simple simulation of some of these drifters was carried out. The trajectory of the simulated drifters diverge from the real one: this result is due to the chaotic transport of passive tracers. However, the separation becomes more evident when velocity fields are less accurate because of lack of measurements, previously filled with nearest neighbourhood interpolation. In the light of such results, the use of LCS could be helpful in understanding the trajectory followed by drifters and passive tracers in general, because they can point out the directions along which transport is likely to develop.

    The international law version of the doctrine of uti possidetis in Rome law originated in Latin America independence,and then was applied in the African decolonization and disintegrations of some Eastern European countries.The doctrine had been applied in several cases by ICJ.The main role of this doctrine in territorial demarcation is to freeze the current territory situation just like the camera to take photographs.The "photographs" shall play the function of evidence in the disputes.If there are no any clear administrative borders,the doctrine can't be applied easily.Sometimes,the application of uti possidetis leads to new disputes and conflicts with self-determination.Though its role is limited,the doctrine has potential applications in the coming frontiers disputes.%罗马法中保有合法占有物原则进入国际法领域发端于拉丁美洲,并在非洲独立运动和东欧部分国家解体过程中得到应用。国际法院也在多个判决中适用了该原则。这一原则在领土划界中的主要作用是冻结现有边界状态,即所谓的照相功能,并以此作为未来划界的依据。如果缺乏清晰的行政边界,该原则将无法发挥作用。同时,适用该原则有时会产生新的争端,并与民族自决权相冲突。尽管该原则的作用有限,但是在解决边界问题中仍有一定的现实需求。

    Objectives. We identify symptom patterns among veterans who believe they suffer from Gulf War–related illnesses and characterize groups of individuals with similar patterns. Methods. A mail survey was completed by 1161 veterans drawn from the Gulf War Health Registry. Results. An exploratory factor analysis revealed 4 symptom factors. A K-means cluster analysis revealed 2 groups: (1) veterans reporting good health and few moderate/severe symptoms, and (2) veterans reporting fair/poor health and endorsing an average of 37 symptoms, 75% as moderate/severe. Those in Cluster 2 were more likely to report having 1 or more of 24 medical conditions. Conclusions. These findings are consistent with previous investigations of symptom patterns in Gulf War veterans. This multisymptom illness may be more fully characterized by the extent, breadth, and severity of symptoms reported. PMID:12660208

    Hopkins, T.S. (Brookhaven National Lab., Upton, NY); Garfield, N. III

    1979-01-01

    The thermohaline dynamics of the Gulf of Maine are analyzed from the two year, eight cruise, data set of Colton, Marak, Nickerson, and Stoddard (1968). Six water masses are described: the Maine Surface Water, Maine Intermediate Water, and the Maine Bottom Water as interior water masses; and the Scotian Shelf Water, the Slope Water, and the Georges Bank Water as exterior water masses. Particular attention is given to the formation and disposition of the Maine Intermediate Water. Salt balance, T-S volume, and T-S drift analyses are used to provide transport and mixing estimates for the year 1966. The Slope Water entered at depth through the Northeast Channel at a rate of 2600 km/sup 3//yr; while the Scotian Shelf Water entered the surface and intermediate layers, mostly during winter intrusions, at a rate of 5200 km/sup 3//yr. The surface and intermediate layers exported a total of 7900 km/sup 3//yr in a 3:5 ratio, respectively. The Maine Intermediate Water tends to collect over the Wilkinson Basin during the stratified season, to exit via the Great South Channel during early spring, and to exit via the Northeast Channel during spring and summer. Comparisons are made between the estimated winter heat loss of 280 Ly/d and the observed heat losses of 230 Ly/d (surface layers) and 360 Ly/d (surface and intermediate layers). A limit for the Scotian Shelf Water contribution is about -70 Ly/d. It is concluded that the Maine Intermediate Water is produced locally and that it is exported in significant quantities.

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

    Energy Technology Data Exchange (ETDEWEB)

    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.

    Risk of major depression (depression) was elevated in Australia's Gulf War veterans in a 2000-2002 (baseline) study. A follow up study has measured the Gulf War-related risk factors for depression, also the current prevalence and severity of depression, use of anti-depressant medication, and persistence, remittance or incidence of depression since baseline in Gulf War veterans and a military comparison group. Participants completed the Composite International Diagnostic Interview v.2.1, the 9-item Patient Health Questionnaire and the Military Service Experience Questionnaire, and consented to Repatriation Pharmaceutical Benefits Scheme (RPBS) and PBS linkage. Prevalence of depression (9.7% Gulf War veterans and 7.7% comparison group; adj RR=1.2, 95% CI 0.8-1.7), and pattern of persistence, remittance and incidence of depression since baseline, were similar in the two groups, however veterans reported slightly more severe symptoms (adj median difference 1, 95% CI 0.26-1.74) and were more likely to have been dispensed anti-depressant medication (adj RR=1.56, 95% CI 1.05-2.32). Depression amongst veterans was associated with self-reported Gulf War-related stressors in a dose-response relationship (adj RR 1.06, 95% CI 1.02-1.09). Lower participation rates at follow up resulted in reduced statistical power compared with baseline, Gulf War related stressor data collected at baseline was at risk of recall bias, and RPBS and PBS databases do not capture all dispensed Nervous System medications. More than 20 years after the Gulf War, veterans are experiencing slightly more severe depressive symptoms than a military comparison group, and depression continues to be associated with Gulf War-related stressors.

    Full Text Available A female green turtle was sighted at Pamban along the Gulf of Mannar just after the nesting on the beach on 15th January 2011. Morphometric measurements of the turtle were taken and data suggests that this individual is adult. A total number of laid eggs were 109. The distance between the nesting site and the high tide line was found to be 7 m. The depth and diameter of the nesting pit was 52 and 16 cm, whereas the mean egg diameter and weight were found to be 44.3 mm and 40.5 g respectively. Pamban coast may also be considered an important place for nesting, because of the continuous mixing of waters of GOM and Palk Bay areas, which in turn create current patterns continuously throughout the year in addition to the monsoon season. Conservation of nesting habitat along Gulf of Mannar will be important to maintain the green turtle population.

  1. The Effect of Plate Structure on Intraplate Volcanism, Kodiak-Bowie Seamount Chain, Gulf of Alaska

    Newly acquired ocean bottom seismometer (OBS) and multi-channel seismic (MCS) data in the vicinity of the Kodiak-Bowie Seamount Chain and Aja Fracture Zone reveal the character and structure of the Pacific Plate, overlying sediment, and seamounts in the Gulf of Alaska. Our data include two marine wide-angle OBS profiles, two coincident MCS profiles, and several nearby MCS profiles, including lines parallel to and crossing the Seamount Chain and Fracture Zone. This new data may help to reveal the character of the Kodiak-Bowie Seamount Chain and associated intraplate volcanism, much of which is concealed by the Surveyor and Baranof sedimentary fan systems. The Kodiak-Bowie Seamount Chain stretches over 1000 km across the Gulf of Alaska, from the Aleutian Trench in the northwest to offshore Queen Charlotte Islands in the southeast. The ages of the seamounts range from 24 Ma at Kodiak Seamount in the northwest to ≥0.7 Ma at Bowie Seamount in the southeast. Although the seamounts are largely age-progressive, some members of the chain are dated significantly out of sequence. Previous studies suggest the possibility that the majority of seamounts in the chain could be products of the Bowie plume. The Gulf-wide Aja Fracture Zone intersects the Kodiak-Bowie Seamount Chain in the central Gulf at the location of the seismic lines. Preliminary tomographic inversions of the seismic data reveal significant changes in crustal thickness across the Aja Fracture Zone, including at least a 3 km step up in the moho from south to north. Additionally, the region north of the Fracture Zone exhibits a 3 km thick low velocity zone in the upper crust, which is double the thickness of the same feature south of the fracture zone. This low velocity zone in the upper crust may be representative of intraplate volcanism associated with the Kodiak-Bowie Chain; several higher velocity perturbations within this zone are coincident with the locations of major seamounts. We will further refine

    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.

    Full Text Available Background: There is paucity of data on heart failure (HF in the Gulf Middle East. The present paper describes the rationale, design, methodology and hospital characteristics of the first Gulf acute heart failure registry (Gulf CARE. Materials and Methods: Gulf CARE is a prospective, multicenter, multinational registry of patients >18 year of age admitted with diagnosis of acute HF (AHF. The data collected included demographics, clinical characteristics, etiology, precipitating factors, management and outcomes of patients admitted with AHF. In addition, data about hospital readmission rates, procedures and mortality at 3 months and 1-year follow-up were recorded. Hospital characteristics and care provider details were collected. Data were entered in a dedicated website using an electronic case record form. Results: A total of 5005 consecutive patients were enrolled from February 14, 2012 to November 13, 2012. Forty-seven hospitals in 7 Gulf States (Oman, Saudi Arabia, Yemen, Kuwait, United Gulf Emirates, Qatar and Bahrain participated in the project. The majority of hospitals were community hospitals (46%; 22/47 followed by non-University teaching (32%; 15/47 and University hospitals (17%. Most of the hospitals had intensive or coronary care unit facilities (93%; 44/47 with 59% (28/47 having catheterization laboratory facilities. However, only 29% (14/47 had a dedicated HF clinic facility. Most patients (71% were cared for by a cardiologist. Conclusions: Gulf CARE is the first prospective registry of AHF in the Middle East, intending to provide a unique insight into the demographics, etiology, management and outcomes of AHF in the Middle East. HF management in the Middle East is predominantly provided by cardiologists. The data obtained from this registry will help the local clinicians to identify the deficiencies in HF management as well as provide a platform to implement evidence based preventive and treatment strategies to reduce the burden

    1996-01-01

    Analyses of a primitive equation ocean model simulation of the Atlantic Ocean circulation at 1/6 deg horizontal resolution are presented with a focus on the Gulf Stream region. Among many successful features of this simulation, this letter describes the Gulf Stream separation from the coast of North America near Cape Hatteras, meandering of the Gulf Stream between Cape Hatteras and the Grand Banks, and the vertical structure of temperature and velocity associated with the Gulf Stream. These results demonstrate significant improvement in modeling the Gulf Stream system using basin- to global scale ocean general circulation models. Possible reasons responsible for the realistic Gulf Stream simulation are discussed, contrasting the major differences between the present model configuration and those of previous eddy resolving studies.

    We present new seismic data from the Gulf of Lion located east of the Pyrenees on the continental shelf of the Mediterranean Sea. The deep penetration LISA (Ligurian-Sardinia Sea) seismic lines, the shots of the LISA cruise recorded on land, and the high definition ELF seismic sections allow us to present a complete picture of the tectonics in this area from the surface to the Moho level, and also to document late Miocene-early Pliocene extensional tectonics in the area. Previous studies show a prominent thinning of the crust observed from the Pyrenees towards the Gulf of Lion. The Moho depth varies from 48 km beneath the Axial Range crust (thickened during the Pyrenean Eocene Orogeny) to 21 km below the Catalan Basin in the Gulf of Lion. This crustal thinning occurred mainly during the early Miocene extension of the Mediterranean Sea. Balanced reconstructed geological sections derived from reflection and refraction seismic data allow us to evaluate the stretching factors at the crustal level. A maximum extension of 25 km is computed for the Catalan Basin area. This extension is related to detachments that penetrate the crust as deep as 11 km to the base of the brittle crust. These intra basement detachments have been confused in the past with the Paleozoic acoustic basement. The detachments show a clear listric shape and the geometry of horst and grabens can be explained by a hanging wall and footwall configuration with isostatic rebound of the footwall. The uplift in the Eastern Pyrenees (Albères and Canigou Massifs), on the other hand, is related to the late Miocene-early Pliocene extension we mapped in the area. These elevated features, probably formed by isostatic rebound, are surrounded by deep basins such as the Roussillon and El Empordà depressions. A 1.7 km uplift during the late Miocene-early Pliocene is computed in the offshore part of the Albères Massif. The cause of this Late Miocene-early Pliocene extension is not well explained although an uplift

    Gulf of Mexico (Gulf) fisheries account for 41% of the U.S. marine recreational fish catch and 16% of the nation's marine commercial fish landings. Mercury (Hg) concentrations are elevated in some fish species in the Gulf, including king mackerel, sharks, and tilefish. All five Gulf states have fish consumption advisories based on Hg. Per-capita fish consumption in the Gulf region is elevated compared to the U.S. national average, and recreational fishers in the region have a potential for greater MeHg exposure due to higher levels of fish consumption. Atmospheric wet Hg deposition is estimated to be higher in the Gulf region compared to most other areas in the U.S., but the largest source of Hg to the Gulf as a whole is the Atlantic Ocean (>90%) via large flows associated with the Loop Current. Redistribution of atmospheric, Atlantic and terrestrial Hg inputs to the Gulf occurs via large scale water circulation patterns, and further work is needed to refine estimates of the relative importance of these Hg sources in terms of contributing to fish Hg levels in different regions of the Gulf. Measurements are needed to better quantify external loads, in-situ concentrations, and fluxes of total Hg and methylmercury in the water column, sediments, and food web.

  20. The influence of the Gulf Stream on wintertime European blocking

    2016-09-01

    Wintertime blocking is responsible for extended periods of anomalously cold and dry weather over Europe. In this study, the influence of the Gulf Stream sea surface temperature (SST) front on wintertime European blocking is investigated using a reanalysis dataset and a pair of atmospheric general circulation model (AGCM) simulations. The AGCM is forced with realistic and smoothed Gulf Stream SST, and blocking frequency over Europe is found to depend crucially on the Gulf Stream SST front. In the absence of the sharp SST gradient European blocking is significantly reduced and occurs further downstream. The Gulf Stream is found to significantly influence the surface temperature anomalies during blocking periods and the occurrence of associated cold spells. In particular the cold spell peak, located in central Europe, disappears in the absence of the Gulf Stream SST front. The nature of the Gulf Stream influence on European blocking development is then investigated using composite analysis. The presence of the Gulf Stream SST front is important in capturing the observed quasi-stationary development of European blocking. The development is characterised by increased lower-tropospheric meridional eddy heat transport in the Gulf Stream region and increased eddy kinetic energy at upper-levels, which acts to reinforce the quasi-stationary jet. When the Gulf Stream SST is smoothed the storm track activity is weaker, the development is less consistent and European blocking occurs less frequently.

    Full Text Available 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 (4X1,400 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.

  3. Benthic foraminiferal bathymetry and sea-bed biogeochemistry in the Gulf of Mexico

    Box cores were collected down the slope of the northwest Gulf of Mexico so that the sea-bed biogeochemistry could be compared to established benthic Foraminiferal bathymetric zonations. Pore water geochemistry along with water columns and sedimentologic analyses were used to quantify bottom water temperatures, organic carbon flux, bottom water oxygen content and sedimentary environment. The prominent Foraminiferal boundary between 170 and 200m water depth is associated with position of the mud-line in the northwestern Gulf. Deeper than this, assemblage changes are more gradational and, between 200 and 600m, appear related to gradients in temperature, oxygen supply and organic carbon flux. Between 600 and 2,000m bathymetric zonation correlates to the organic carbon flux profile. An analysis of sediment pore water geochemistry and sedimentary features in the box cores shows that there is a progressive change in the vertical distribution and character of potential microhabitats within the sediments down the slope of the northwest Gulf. This gradient in habitats must influence the generation of benthic Foraminiferal assemblages, and it is largely controlled by the organic carbon flux to the sea-bed.

  12. Sediment Sources in the Persian Gulf

    Sediment Constituent Analysis is an effective tool for identifying sediment sources. Based on several sediment samples taken from different sites all over the Iranian coastlines, we have been able to show that an important portion of sediment on the beaches in the Persian Gulf is bio-clastic; that is, biologically created from the coral environment as well as other marine habitats. Unlike mineral (clastic) sediments, carbonate sediments are born not made. Furthermore, carbonate sand constituents are generally less durable than their quartz and mineral counterparts, and break down relatively quickly. Therefore, destruction of reefs and degradation of marine habitat are certain to reduce the sand supply to the shoreline in the Persian Gulf that is necessary to maintain beaches. Carbonate sands are also found on the coastline of the Oman Sea. One of the striking things about the sediments along the coastline of Iran is the high percentage of carbonate material. Molluscan debris is common, even ubiquitous. This reflects the populations living in the offshore waters. Some molluscs thrive in high-energy sandy environments, others like finer sediments. Some live at the surface, while some burrow down as much as a half-metre. A great deal of information can be gained from the study of the species of mollusk and their distribution in the sediments. This paper introduces a few case studies done in different parts of the Persian Gulf by using this method as a general assessment toolbox.

    Hepatocellular carcinoma (HCC) has a unique geographic distribution that is likely to be determined by specific etiologic factors. There is a distinctive difference in sex and age related occurrence of disease. In the Gulf region, there are contradicting data on the prevalence and death rates due to HCC. In this review we highlight some aspects of HCC specific to the Gulf region. A retrospective analysis of 150 patient's data is presented, including demographic, epidemiological, aetiological disease status assessment with child Pugh criteria, modes of treatment and treatment related outcome. Hepatitis C virus (HCV) infection was the most common (45%) documented etiology, similar to Western European countries, followed by hepatitis B virus (HBV) infection in 27% of cases, alcoholic liver disease only in six patients (4%). Child-Pugh assessment was A in 33%, B in 37% and C in 30% of observed patients. Surgery (liver resection or transplantation) was performed in 12% and local ablation in 5% of cases. The others were treated by chemo-embolization in 17% and by systemic therapy with sorafenib in 13% of patients. Nearly half of the patients (53%) were in advanced stages and received palliative treatment. To improve the outcome of treatment in HCC patients in the Gulf region, an effective and strategic screening program must be implemented for early diagnosis and treatment to improve the outcome of this mostly fatal disease.

    These remotely sensed, geographically referenced elevation measurements of Lidar-derived coastal topography were produced as a collaborative effort between the U.S. Geological Survey (USGS), Florida Integrated Science Center (FISC), St. Petersburg, FL and the National Aeronautics and Space Administration (NASA), Wallops Flight Facility, VA. One objective of this research is to create techniques to survey areas for the purposes of geomorphic change studies following major storm events. The USGS Coastal and Marine Geology Program's National Assessment of Coastal Change Hazards project is a multi-year undertaking to identify and quantify the vulnerability of U.S. shorelines to coastal change hazards such as effects of severe storms, sea-level rise, and shoreline erosion and retreat. Airborne Lidar surveys conducted during periods of calm weather are compared to surveys collected following extreme storms in order to quantify the resulting coastal change. Other applications of high-resolution topography include habitat mapping, ecological monitoring, volumetric change detection, and event assessment. The purpose of this project is to provide highly detailed and accurate datasets of the northern Gulf of Mexico coastal areas, acquired on September 19, 2004, immediately following Hurricane Ivan. 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 Airborne Advanced 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 RGB (red-green-blue) digital camera, a high-resolution multi

  15. Gulf of Bothnia receives high concentrations of potentially toxic metals from acid sulphate soils

    2006-07-01

    An estimated 460000 ha of acid sulphate soil (AS soil) occur within the river catchments bordering the Gulf of Bothnia in Finland and Sweden. This soil type exists because extensive areas of sulphide-bearing Holocene sediments have been drained for agricultural purposes, resulting in oxidation of metal sulphides to sulphuric acid and the concomitant formation of these acidic, environmentally-unfriendly soils. The aim of this study was to compare median values of metal concentrations in rivers discharging into the Gulf of Bothnia and obtain a uniform picture of to what extent these rivers are affected by AS-soil leaching. Dissolved element concentrations for arsenic (As), cadmium (Cd), chromium (Cr), iron (Fe), nickel (Ni), lead (Pb), and zinc (Zn) were determined in 47 rivers (catchment size > 500 km2) discharging into Gulf of Bothnia (a few into Gulf of Finland) along the coastline of Finland and Sweden. Water chemistry data was obtained from the Environmental Information System (HERTTA) database at the Finnish Environment Institute, the publicly available online database at Swedish University of Agricultural Sciences, Department of Environmental Assessment, and from a previous study of the authors. One area in central-western Finland proved to have highly elevated concentrations of Cd, Ni and Zn, and they all occurred with a similar spatial pattern and had the highest concentrations in rivers Teuvanjoki and Maalahdenjoki. This is caused by AS-soil leaching. The metalloid As and the metals Cr, Fe, Pb did not display this pattern and are, therefore, in line with previous studies, not leached abundantly from the AS soils, although they overall occur at somewhat higher concentrations in the Finnish as compared with those in the Swedish rivers. Thorough planning of land-use operations (e.g. land reclamation through ditching, dredging of rivers and estuaries, etc.) in AS-soil landscapes should be necessary, which is currently not the case, to reduce the high

    A significant percentage of disaster survivors experience negative psychological, physical, and social outcomes after a disaster. The current study advances the literature concerning the Deepwater Horizon Oil Spill (the Gulf Oil Spill) while addressing weaknesses of previous research. The current study includes a clinical sample of 1,119 adults receiving mental health services in the coastal counties of Mississippi after the Gulf Oil Spill. The levels of clinical symptoms reported on the Depression Anxiety Stress Scales (DASS-21) and PTSD Checklist (PCL-S) were examined in relation to other domains of functioning potentially affected by the spill (finances, social relationships, and physical health). Participants reported substantial worsening of their functioning across each life domain. Furthermore, chronic problems in living related to the Gulf Oil Spill were significantly associated with higher levels of psychological distress, although the pattern differed somewhat for persons living above and below the poverty line, with lower income individuals reporting a higher level of overall distress. These data support the perspective that the experience of the Gulf Oil Spill is strongly associated with a deleterious effect on mental health symptoms.

  18. Hypoxia in the Northern Gulf of Mexico

    Energy Technology Data Exchange (ETDEWEB)

    Dale, Virginia H [ORNL

    2010-01-01

    Since 1985, scientists have been documenting a hypoxic zone in the Gulf of Mexico each year. The hypoxic zone, an area of low dissolved oxygen that cannot support marine life, generally manifests itself in the spring. Since marine species either die or flee the hypoxic zone, the spread of hypoxia reduces the available habitat for marine species, which are important for the ecosystem as well as commercial and recreational fishing in the Gulf. Since 2001, the hypoxic zone has averaged 16,500 km{sup 2} during its peak summer months, an area slightly larger than the state of Connecticut, and ranged from a low of 8,500 km{sup 2} to a high of 22,000 km{sup 2}. To address the hypoxia problem, the Mississippi River/Gulf of Mexico Watershed Nutrient Task Force (or Task Force) was formed to bring together representatives from federal agencies, states, and tribes to consider options for responding to hypoxia. The Task Force asked the White House Office of Science and Technology Policy to conduct a scientific assessment of the causes and consequences of Gulf hypoxia through its Committee on Environment and Natural Resources (CENR). In 2000 the CENR completed An Integrated Assessment: Hypoxia in the Northern Gulf of Mexico (or Integrated Assessment), which formed the scientific basis for the Task Force's Action Plan for Reducing, Mitigating, and Controlling Hypoxia in the Northern Gulf of Mexico (Action Plan, 2001). In its Action Plan, the Task Force pledged to implement ten management actions and to assess progress every 5 years. This reassessment would address the nutrient load reductions achieved, the responses of the hypoxic zone and associated water quality and habitat conditions, and economic and social effects. The Task Force began its reassessment in 2005. In 2006 as part of the reassessment, USEPA's Office of Water, on behalf of the Task Force, requested that the U.S. Environmental Protection Agency (USEPA) Science Advisory Board (SAB) convene an independent

    Evaluating the quality of cultivated land comprehensively and systematically is an important prerequisite in performing, demarcating, and conducting high standards of prime farmland scientifically. Taking Tunchang county, Hainan Province as an example, these indexes are chosen to evaluate the quality of cultivated land in the paper as following: topography, erosion condition of soil, ecological system service value, flood disaster, connection, etc, on the basis of comprehensive consideration of nature quality and location condition. It shows that the ecological quality is very important in prime farmland evaluation, and index system is improved. The result: 88.91% of cultivated land is demarcated into prime farmland, with comprehensive evaluating score equal or larger than 70, mainly in the central south and north of the platforms and plains regions of Tunchang country. Contrastive analysis was studied between the method of this paper (method 1) and natural quality of agricultural land (method 2) in demarcating prime farmland. Cultivated land of the study area is classified into four type regions, namely: Type region I, Type region II, Type region III, Type region IV. Among them, Type region I is described as the farmland area demarcated by the above two methods, which is the largest part (84.49%) and has some essential characteristics such as good nature quality, convenient location convenient, less natural disasters, and soil erosion, as well as fairly flat land. Except that, prime farmland is close to towns or rural settlements in spatial distribution, and their average patch area is large and is in the obviously centralized distribution, which is easy to agricultural scaled production and mechanization. Type region II is chosen through method 2, only occupies 4.42%of the area, but distributes in every town. This kind of cultivated land is mainly west and east of the mountainous and hilly regions. The patches are much smaller than Type region I or Type region

    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.

    In the present study, cadmium and lead concentrations were compared in barnacles, ghost shrimps, polychaetes, bivalves, and sediment from ten different locations along the intertidal zone of the Persian Gulf and the Gulf of Oman. The results revealed significant differences in the heavy metal concentrations between the organisms with barnacles showing, by far, the highest metal concentrations. The bioaccumulation factor of Cd in different animals follows this pattern with barnacles>bivalves>polychaetes>ghost shrimps, while the pattern for Pb was barnacles>polychaetes>bivalves>ghost shrimps. In most of the stations, sediments showed the lowest lead and cadmium concentrations. Therefore, it is concluded that barnacles with Pb concentrations between 0.17 and 2,016.1 μg/g and Cd concentrations ranging from 0.4 to 147.1 μg/g are the best organisms to be employed in monitoring programs designed to assess pollution with bioavailable metals in the Persian Gulf and the Gulf of Oman.

    A cyclonic ring, which had separated from the Gulf Stream 7 months earlier and traveled 500 kilometers westward, collided with the stream in September 1977. Within 3 days the ring and stream joined to form a sharp S-shaped meander. Shipboard expendable temperature probes and four bottom-moored inverted echo sounders were used to obtain synoptic descriptions of the rejoining process.

  14. [The Gulf War Syndrome twenty years on].

    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 NASA Applied Sciences Program created the Gulf of Mexico Initiative (GOMI) in 2007 "to enhance the region s ability to recover from the devastating hurricanes of 2005 and to address its coastal management issues going into the future." The GOMI utilizes NASA Earth science assets to address regional priorities defined by the Gulf of Mexico Alliance, a partnership formed by the states of Alabama, Florida, Louisiana, Mississippi, and Texas, along with 13 federal agencies and 4 regional organizations to promote regional collaboration and enhance the ecological and economic health of the Gulf of Mexico. NASA's GOMI is managed by the Applied Science and Technology Project Office at Stennis Space Center and has awarded over $18 million in Gulf of Mexico research since 2008. After the Deepwater Horizon oil spill, GOMI personnel assisted members of the Gulf of Mexico Alliance with obtaining NASA remote sensing data for use in their oil spill response efforts.

  2. Migrant workers: victims of war in Gulf.

    Science.gov (United States)

    1992-01-01

    The Persian Gulf War forced millions of migrant workers in the region to return home, causing hardship not only on the workers but also on their home countries. Prior to the war, the region's oil wealth had attracted migrants from around the world. By 1990, some 3 million resided in Iraq and Kuwait alone. Many more worked in other Gulf countries. But only 2 months after the Iraqi invasion of Kuwait, over 2 million workers had fled the region or had been returned home. Yemenis and Egyptians alone accounted for 750,000 and 1/2 million workers, respectively. There were also an estimated 600,000 Asians. Although many of the migrants were unskilled laborers, many also were skilled laborers and professionals. Jordanians and Palestinians made up much of the Kuwaiti civil service. As the war unfolded, it became clear that the migrant workers lacked any of the legal rights and protection granted to other citizens. Many workers were not allowed to return home because of their importance to the economy. Others, like some 35,000 Sri Lankan housemaids in Kuwait, were stranded in the war zone, lacking the money and means to return home. In most cases, the workers also suffered from frozen bank accounts, unpaid wages and benefits, and property loss. Their return home also created problems for their countries. Jordan's population increased by 10% in 1990 due to the returning population. Yemen's unemployment increased from 10% to 25%. As a result of the Gulf war experience, the UN General Assembly adopted the International Convention on the Rights of Migrant Workers and their Families, which must now be ratified by 20 nations before implementation begins.

    The Persian Gulf and the Gulf of Oman locate at the northwest of the Arabian Sea, with the total area more than 50,0000 km2. The Persian Gulf is a semi-enclosed subtropical sea with high water temperature, extremely high salinity, and an average depth of 50 meters. By the Strait of Hormuz, the Persian Gulf is connected to the Gulf of Oman which is significantly affected by the monsoonal winds and by water exchange between the Arabian Sea and the Persian Gulf. Algal blooms occurred frequently in the Persian Gulf and the Gulf of Oman, and some of them are harmful algal blooms which may lead to massive fish death and thereby serious economic loss. Due to the widely spatial coverage and temporal variation, it is difficult to monitoring the dynamic of the algal bloom based on in situ measurement. In this study, we used the remote sensing data from the Moderate Resolution Imaging Spectroradiometer (MODIS) onboard the Aqua satellite to investigate a massive algal bloom event in the Persian Gulf and the Gulf of Oman during 2008-2009. The time series of MODIS-derived chlorophyll concentration (Chl-a) indicated that the bloom event with high Chl-a concentration ( 60 percent higher than corresponding climatological data) appeared to lasting more than 8 months from autumn of 2008 to spring of 2009. In addition, the bloom was widespread from the Persian Gulf to the Gulf of Oman and neighboring open ocean. The MODIS-derived net primary production (NPP) collected from MODIS showed the same trend with Chl-a. Multiple forces including upwelling, dust deposition was taken into account to elucidate the mechanisms for the long-lasting algal bloom. The time series chlorophyll concentration of the Persian Gulf emerges a significant seasonal pattern with maximum concentrations seen during the winter time and lowest during the summer. It also indicated slight disturbances occurred in June (May/July) and December (November/ January) in some years. The sea surface temperature and water

    A well bore intersection was achieved ahead of schedule with a steerable drilling system in the Gulf of Mexico. A computer-generated proximity survey comparing the directional surveys of the initial and replacement wells, confirmed that the wells were within 1 ft. of each other near the planned intersection depth of 8,890 ft. All objectives for the 9,050-ft. replacement well were accomplished 4 days ahead of schedule. This operation illustrates the effectiveness of the steerable drilling system for obtaining better directional control, increased drilling efficiently, and reduced overall drilling time. This article explains how the project was completed.

    The specific scientific tasks addressed in the July 1990 Gulf Stream (GS) experiment were the following: (1) Kelvin wake behavior across fronts at various ship speeds, (2) the physics of temperature front/radar cross section (RCS) mismatch, (3) wave-current interactions in curvature fronts, and (4) the hydrodynamic structure and origin of synthetic-aperture-radar (SAR) slick-like features. Overall, the GS Experiment was most successful, and about 60 percent of the planned data was collected. On-going efforts concentrate on the analysis and interpretation of the data. An overview of the experiment and preliminary results of the data analysis are given.

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

    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.

  7. Gulf Stream marine hydrokinetic energy resource characterization off Cape Hatteras, North Carolina

    2015-12-01

    The Gulf Stream off North Carolina has current velocities that approach 3 m/s and an average volume transport of 90 Sv (1 Sv= 106 m3/s) off of Cape Hatteras, making it the most abundant MHK (Marine Hydrokinetic Energy) resource for the state. Resource availability at a specific location depends primarily on the variability in Gulf Stream position, which is least offshore of Cape Hatteras after the stream exits the Florida Straits. Proximity to land and high current velocities in relatively shallow waters on the shelf slope make this an optimal location to quantify the MHK energy resource for NC. 3.5 years of current measurements beginning in August of 2013 from a moored 150 kHz ADCP (Acoustic Doppler Current Profiler) at an optimal location for energy extraction quantify the available energy resource and its variability, and establish the skill of a Mid-Atlantic Bight and South Atlantic Bight Regional Ocean Model in predicting the MHK energy resource. The model agrees well with long-term observed current averages and with weekly to monthly fluctuations in the current speeds. Model and observations over the first 9 months of the ADCP deployment period both averaged 1.15 m/s thirty meters below the surface. The model under estimates observed current speeds for the higher frequency current fluctuations of days to weeks. Comparisons between the model and ADCP observed currents, and velocity derived power density over the entire 3.5 years of observations demonstrate the significant inter-annual variability in power density. Shipboard 300 kHz ADCP cross-stream transects and hourly surface currents measurements off Cape Hatteras from a network of land based HF (high frequency) radars further quantify available MHK energy and assess model skill. Cross-stream transects were made with a vessel-mounted 300 kHz ADCP on a line from the 100-1000m isobaths, and measured currents in the top 100m. These measurements demonstrate the variability in the resource with water depth, and

  8. Preliminary estimates of Gulf Stream characteristics from TOPEX data and a precise gravimetric geoid

    Science.gov (United States)

    Rapp, Richard H.; Smith, Dru A.

    1994-01-01

    TOPEX sea surface height data has been used, with a gravimetric geoid, to calculate sea surface topography across the Gulf Stream. This topography was initially computed for nine tracks on cycles 21 to 29. Due to inaccurate geoid undulations on one track, results for eight tracks are reported. The sea surface topography estimates were used to calculate parameters that describe Gulf Stream characteristics from two models of the Gulf Stream. One model was based on a Gaussian representation of the velocity while the other was a hyperbolic representation of velocity or the sea surface topography. The parameters of the Gaussian velocity model fit were a width parameter, a maximum velocity value, and the location of the maximum velocity. The parameters of the hyperbolic sea surface topography model were the width, the height jump, position, and sea surface topography at the center of the stream. Both models were used for the eight tracks and nine cycles studied. Comparisons were made between the width parameters, the maximum velocities, and the height jumps. Some of the parameter estimates were found to be highly (0.9) correlated when the hyperbolic sea surface topography fit was carried out, but such correlations were reduced for either the Gaussian velocity fits or the hyperbolic velocity model fit. A comparison of the parameters derived from 1-year TOPEX data showed good agreement with values derived by Kelly (1991) using 2.5 years of Geosat data near 38 deg N, 66 deg W longitude. Accuracy of the geoid undulations used in the calculations was of order of +/- 16 cm with the accuracy of a geoid undulation difference equal to +/- 15 cm over a 100-km line in areas with good terrestrial data coverage. This paper demonstrates that our knowledge or geoid undulations and undulation differences, in a portion of the Gulf Stream region, is sufficiently accurate to determine characteristics of the jet when used with TOPEX altimeter data. The method used here has not been shown to

A comparison of the parameters derived from 1-year TOPEX data showed good agreement with values derived by Kelly (1991) using 2.5 years of Geosat data near 38 deg N, 66 deg W longitude. Accuracy of the geoid undulations used in the calculations was of order of +/- 16 cm with the accuracy of a geoid undulation difference equal to +/- 15 cm over a 100-km line in areas with good terrestrial data coverage. This paper demonstrates that our knowledge or geoid undulations and undulation differences, in a portion of the Gulf Stream region, is sufficiently accurate to determine characteristics of the jet when used with TOPEX altimeter data. The method used here has not been shown to

  10. Gulf States and the Conflict between India and Pakistan

    2010-05-01

    Full Text Available Traditional cultural and economic ties between the Indian subcontinent and the Gulf region have existed for several centuries now. Strengthened further, both India and Pakistan continue to have important economic and strategic ties with the countries of the Gulf. While the Gulf region offers substantial economic advantages to both, they also have the potential to make positive interventions in the bilateral conflict between India and Pakistan. The following chapter analyses the role and position of the Gulf Arab States - in particular the member states of the Gulf Cooperation Council (GCC, and their potential in acting as a buffer for the Indo-Pak conflict. It will evaluate the official positions of the Gulf region towards various aspects of the Indo-Pak conflict. The Gulfcountries have often voiced their positions at regional and internationalforums. An additional aspect of this relationship is that the Gulf States are also members of the Organization of Islamic Conference (OIC, a pan- Islamic body which has often addressed issues of contention between India and Pakistan, particularly with respect to Kashmir. Through an academic understanding of the issues and incorporating viewpoints of experts in the area, the chapter seeks to provide fresh insights into an aspect which has the possibility of becoming a crucial incentive for peace between India and Pakistan.

  11. Phytoplankton and sediments in Gulf of Mexico

    Science.gov (United States)

    2002-01-01

    Affected both by terrestrial factors like agriculture, deforestation, and erosion, and by marine factors like salinity levels, ocean temperature and water pollution, coastal environments are the dynamic interface between land and sea. In this MODIS image from January 15, 2002, the Gulf of Mexico is awash in a mixture of phytoplankton and sediment. Tan-colored sediment is flowing out into the Gulf from the Mississippi River, whose floodplain cuts a pale, wide swath to the right of center in the image, and also from numerous smaller rivers along the Louisiana coast (center). Mixing with the sediment are the multi-colored blue and green swirls that reveal the presence of large populations of marine plants called phytoplankton. Phytoplankton populations bloom and then fade, and these cycles affect fish and mammals-including humans-higher up the food chain. Certain phytoplankton are toxic to both fish and humans, and coastal health departments must monitor ecosystems carefully, often restricting fishing or harvesting of shellfish until the blooms have subsided.

  15. Ecologic Atlas of Benthic Foraminifera of the Gulf of Mexico

    Science.gov (United States)

    Tietjen, John H.

    Because of their importance as indicators of petroleum deposits, the benthic foraminifera of the Gulf of Mexico are one of the most intensely studied groups of animals in the world. This is especially true of the foraminifera inhabiting the shallow shelf region of the northern and eastern Gulf; much less is known about the animals of the southern shelf, continental slope, and abyssal plains. The author spent 10 years examining collections from various not well-known areas of the Gulf; this atlas is a synthesis of distributional data from approximately 4500 previously known stations, plus new information from 400 additional stations.

  16. Evidence for atmospheric carbon dioxide variability over the Gulf Stream

    Bufton, J. L.

    1984-01-01

    Two airborne surveys of atmospheric carbon dioxide concentration have been conducted over the Gulf Stream off the east coast of Virginia and North Carolina on September 7-8, 1983. In situ CO2 data were acquired at an aircraft altitude of 300 m on trajectories that transcected the Gulf Stream near 36 deg N 73 deg W. Data show evidence of a CO2 concentration increase by 4 ppm to 15 ppm above the nominal atmospheric background value of 345 ppm. These enhanced values were associated with the physical location of the Gulf Stream prior to the passage of a weak cold front.

  17. SAR observations of the Gulf Stream during SWADE

    Science.gov (United States)

    Vachon, Paris W.; Liu, Antony K.; Mollo-Christensen, Erik

    1992-01-01

    The Surface Wave Dynamics Experiment (SWADE) has gathered SAR observations of the Gulf Stream that show a change in ocean surface brightness; this may be due to the effects of a change in air-sea temperature difference across the observed edge, where the boundary is defined by warm, quickly flowing Gulf Stream water and cooler, relatively stationary shelf water. The two images discussed indicate the possibility of deepening understanding of Gulf Stream front dynamics by using the abundant spatial data of SAR imagery, in conjunction with more conventional (point-like) data on hydrography and currents.

  18. Gulf Stream density structure and transport during the past millennium

    OpenAIRE

    Lund, David C.; Lynch-Stieglitz, Jean; Curry, William B.

    2006-01-01

    The Gulf Stream transports approximately 31 Sv (1 Sv = 10^6 m^3 s^(-1)) of water and 1.3 10^(15) W of heat into the North Atlantic ocean. The possibility of abrupt changes in Gulf Stream heat transport is one of the key uncertainties in predictions of climate change for the coming centuries. Given the limited length of the instrumental record, our knowledge of Gulf Stream behaviour on long timescales must rely heavily on information from geologic archives. Here we use foraminifera from a su...

    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. PMID:27362839

    Full Text Available In this work, serial production lines with finished goods buffers operating in the pull regime are considered. The machines are assumed to obey Bernoulli reliability model. The problem of satisfying customers demand is addressed. The level of demand satisfaction is quantified by the due-time performance (DTP, which is defined as the probability to ship to the customer a required number of parts during a fixed time interval. Within this scenario, the definitions of DTP bottlenecks are introduced and a method for their identification is developed.

    2001-12-01

    The time-space behavior of thermohaline properties of the water masses in the Gulf of Nicoya, a tropical estuary in the Costa Rican Pacific coast, was studied by sampling monthly from April 1992 to April 1993. The saline field has a seasonal maximum during April, a month before the maximum temperature is observed. Minimun values were observed during October and November, in the rainy season. A defined surface saline front is located towards the east of Negritos Islands; it is produced by the interaction of freshwater from the Tarcoles River and the oceanic waters that enter through the occidental coast of the gulf. The vertical distribution of temperature and salinity indicates a gulf whose internal area is highly stratified in the rainy season, and much less stratified, or even well mixed in the dry season. The outer area of the Gulf is stratified throughout the year.

    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...... to migrants, but also with regard to local populations. In addition to the contested nature of citizenship, migrants' lack of citizenship rights fulfils distinctive functions in what Saskia Sassen calls 'global cities'. This concept links the Arab world with a new phenomenon of globalized migration in which...... 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....

    Full Text Available The inhabitants of the Arabian Gulf were among the world’s earliest maritime traders. Their ships sailed regularly between the Bronze Age civilizations of Mesopotamia, Bahrain and the Indus Valley, and they reached China by sea in the eighth century AD, thus bypassing the long and perilous overland Silk Road route across Central Asia. Now excavations at a coastal site in Kuwait by a team from the Institute have revealed even earlier evidence of maritime activity in the Gulf.

    2010-01-01

    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.

  8. Polarization and wavelength diversities of Gulf Stream fronts imaged by AIRSAR

    Science.gov (United States)

    Lee, J. S.; Jansen, R. W.; Marmorino, G. O.; Chubb, S. R.

    1995-01-01

    During the 1990 Gulf Stream Experiment, NASA/JPL AIRSAR imaged the north edge of the Gulf Stream near the coast of Virginia. Simultaneous in-situ measurements of currents, temperatures, salinities, etc. were made for several crossings of the north edge by the R/V Cape Henlopen. Measurements identified two fronts with shearing and converging flows. The polarimetric SAR images from the fronts showed two bright linear features. One of them corresponds to the temperature front, which separated the warm Gulf Stream water to the south from a cool, freshwater filament to the north. The other line, located about 8 km north of the temperature front, is believed to correspond to the velocity front between the filament and the slope water. At these fronts, wave-current interactions produced narrow bands of steep and breaking waves manifesting higher radar returns in polarimetric SAR images. In general, our AIRSAR imagery shows that the signal-to-clutter ratio of radar cross sections for the temperature front is higher than that of the velocity front. In this paper, we study the polarization and wavelength diversities of radar response of these two fronts using the P-, L-, and C-Band Polarimetric SAR data. The north-south flight path of the AIRSAR crossed the temperature front several times and provided valuable data for analysis. Three individual passes are investigated. We found that for the temperature front, the cross-pol (HV) responses are much higher than co-pol responses (VV and HH), and that P-Band HV has the highest signal to clutter ratio. For the velocity front, the ratio is the strongest in P-Band VV, and it is indistinguishable for all polarizations in C-Band. The radar cross sections for all three polarization (HH, HV, and VV) and for all three bands are modelled using an ocean wave model and a composite Bragg scattering model. In our initial investigations, the theoretical model agrees qualitatively with the AIRSAR observations.

    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.

    The purpose of this paper is to propose the hypotheses of land use dynamic characteristics in urban-rural fringe and verified a new demarcation method based on dynamic indicator for urban-rural fringe supporting by the land use information from 1999 and 2010 TM images. Methods include theoretical deduction and empirical analysis. The results show 1 ) From urban core to rural area, the dynamic degree of land use increases slowly at first, then rapid rise with local shocks will occur from the inner edge to the outer edge of the urban-rural fringe, and subsequently with a sudden drop to a lower level. This validates the hypotheses of land use dynamic characteristics of urban-rural fringe. Therefore the definition of urban-rural fringe boundary by land use dynamic indicators is feasible; 2) the empirical analysis of demarcation method for Beijing urban-rural fringe based upon land use dynamic degree finds that inner edge of Beijing urban-rural fringe should be close the Third Circuit Road or Forth Circuit Road of Beijing. The western outer edge of it might be approached the inside Fifth Circuit Road and other direction of outer edges will be close to the Sixth Circuit Road of Beijing. The paper concludes that the feasibility of the proposed method and it will provide a new view of the demarcation on urban-rural fringe.%研究目的:在北京市1999年和2010年两期LandsatTM数据支持下,提出并验证城乡交错带土地利用动态变化特征假设和动态指标界定城乡交错带边界的新方法。研究方法:理论假设和实证分析相结合。研究结果:(1)由城市核心区到外围腹地,土地利用动态度具有先缓慢增加,至城乡交错带内缘时发生突变、急速升高、局部可能发生震荡,到城乡交错带的外缘发生突降至较低水平的特征;(2)采用土地利用动态度界定城乡交错带实证分析认为,北京市城乡交错带的内缘大部分在三、四环路之间,外缘西

    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.

    @@ Drilling rig Decpwater Horizon in the Gulf of Mexico, leased by BP PLC from Transocean Ltd., ex-ploded and caught on fire on April 20, 2010. The drilling location is at some 50 miles (80 kilometers) off the coast of Louisiana, USA. The rig sank on April 22. Since then, oil has been pouring into the Gulf from the blown-out undersea well. As reported by US Today and Calgary Herald on July 3, an estimated 35 000 to 60 000 barrels of oil per day has been gush-ing out of the ruptured well into the Gulf. That means amounts to a total of 1.9 to 3.6 million barrels of oil so far have gushed into the Gulf. Using the high end of that estimate, the spill has now surpassed the 1979 Ixtoc blowout, which took nine months to cap and dumped estimated 3.3 million barrels (140 000 million gallons) into the Gulf of Mexico. It is topped only by the deliberate release of six to eight million barrels of crude oil by Iraqi troops who destroyed tankers and oil terminals and set wells ablaze in Kuwait during the 1991 Gulf War.

    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. The absent of sign or trace ofthe TPF Path to the west suggested that there

    Full Text Available Geophysical, temperature, and discrete depth-stratified geochemical data illustrate differences between an actively venting mud volcano and a relatively quiescent brine pool in the Gulf of Mexico along the continental slope. Geophysical data, including laser-line scan mosaics and sub-bottom profiles, document the dynamic nature of both environments. Temperature profiles, obtained by lowering a CTD into the brine fluid, show that the venting brine was at least 10°C warmer than the bottom water. At the brine pool, two thermoclines were observed, one directly below the brine-seawater interface and a second about one meter below the first. At the mud volcano, substantial temperature variability was observed, with the core brine temperature being either slightly (~2°C in 1997 or substantially (19°C in 1998 elevated above bottom water temperature. Geochemical samples were obtained using a device called the "brine trapper" and concentrations of dissolved gases, major ions and nutrients were determined using standard techniques. Both brines contained about four times as much salt as seawater and steep concentration gradients of dissolved ions and nutrients versus brine depth were apparent. Differences in the concentrations of calcium, magnesium and potassium between the two brine fluids suggests that the fluids are derived from different sources or that brine-sediment reactions are more important at the mud volcano than the brine pool. Substantial concentrations of methane and ammonium were observed in both brines, suggesting that fluids expelled from deep ocean brines are important sources of methane and dissolved inorganic nitrogen to the surrounding environment.

    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.

    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.

    The Littoral Acoustic Demonstration Center (LADC) deployed three environmental and acoustic moorings in a downslope line just off the Mississippi River Delta in the northern Gulf of Mexico in an area of a large concentration of sperm whales in July 2001. The measurement of whale vocalizations and, more generally, ambient noise, were the objectives of the experiment. Each mooring had a single hydrophone autonomously recording Environmental Acoustic Recording System (EARS) obtained from the U.S. Naval Oceanographic Office and modified to recorded signals up to 5859 Hz continuously for 36 days. Also, self-recording, environmental sensors were attached to the moorings to obtain profiles of time series data of temperature and salinity. Satellite imagery and NOAA mooring data were gathered for an analysis of eddy formations and movement in the Gulf. This paper will discuss the possible environmental impact of two events that occurred during the experiment: the passage of Tropical Storm Barry and the movement of the remnants of an eddy in the area. Discussed also will be the expected effects of these events on acoustic propagation based on modeling, which are carried out for long range and low frequency (300 km and 500 Hz) using the normal-mode acoustic model SWAMP (Shallow Water Acoustic Modal Propagation by M. F. Werby and N. A. Sidorovskaia) and for short range and high frequency (10 km and 5000 Hz) using the parabolic-equation acoustic model RAM (Range-dependent Acoustic model by M. Collins).

    Full Text Available From five Gulf countries over the 2007-2012 period, this paper offers a comprehensive investigation for these managerial skills during and after the Financial Crisis (FC of 2007- 2008; it also inspects the relative differences in performance between equity conventional mutual funds (CMFS and Islamic ones. The results show no evidence of over-or-under performance for the fund managers due to these two skills, where there are no structuralchanges for the regression line across the two sub-periods, but it reveals the superiority of equity CMFS performance in Kuwait in particular along the overall period. Thus, it seemsthat if the investors cannot gain superior returns by investing in the Gulf mutual funds on general, they may attain a comparative advantage by investing in the conventional fundsagainst the Islamic ones especially in Kuwait. It also implies that the ethical screening, which is adopted by the Islamic funds of Kuwait, already limits their diversification  opportunities and then adversely affects their performance.JEL classification: G1; G2Keywords: Capital markets, Islamic mutual funds, performance evaluation, market timing ability, stock picking ability

  3. Foraminifera as indicators of slope environments in the northern Gulf of Mexico

    1991-03-01

    Paleobathymetric reconstructions of the northern Gulf of Mexico are based mainly on models derived from distribution patterns of modern benthic foraminiferal taxa. This method of paleoenvironmental analysis is commonly supplemented by information derived from species diversity patterns, planktonic/benthonic ratios, and shell-type ratios. Based on these lines of evidence, environment subdivision of the northern Gulf slope in the 1960s recognized two zones, upper bathyal (200 to 500 m) and lower bathyal (500 to 2,000 m). Later studies defined three bathyal depth zones; upper bathyal (200 to 500 m), middle bathyal (500 to 1,000 m), and lower bathyal (1,000 to 2,000 m). Both qualitative and quantitative analyses indicate that this tripartite pattern is the natural subdivision of the slope that can be recognized in foraminiferal assemblages at both the species and generic level. The movement of exploration onto the slope in the 1980s stimulated attempts to further subdivide the bathyal realm. For example, a recent study defined a model consisting of seven a priori bathyal depth zones and statistically investigated zone membership on the basis of generic assemblages. Another approach involved analysis of the depth distribution of assemblages defined by shape of test rather than taxonomic composition. All of these studies utilize modern models of depth relationships but such models become less precise in increasingly older strata. To address this problem, time-specific paleobathymetric models can be derived for fossil foraminiferal assemblages organized along datum planes.

    Loop Current, LC, path variability exhibits a continuum of spatial and temporal scales, all are called meanders in this work. They arise from a variety of processes, including short and long waves, frontal eddies with or without closed cores and developing baroclinic instability. They have been extensively studied with satellite sea surface temperature SST, and height, SSH. Yet, these systems provide an incomplete view into LC meandering: SST measurements are hampered by cloud coverage and low thermal contrast in summer months and SSH measurements by altimeter temporal and spatial resolution. In an effort to resolve LC meander temporal and spatial scales, they are investigated using a mesoscale resolving in situ array deployed in the Gulf of Mexico. The array, which consisted of twenty-five inverted echo sounders with pressure gauges, PIES, and current meter moorings, was deployed April 2009 and recovered in October-November 2011. The broad extent of the array, nominally 89° W to 85° W, 25° N to 27° N, enabled quantitative mapping of the regional circulation. LC meander properties are characterized as a function of spatial distribution of energy, frequency, wavenumber, and phase speed. Dispersion characteristics and meander scales are comparable to those found in the Gulf Stream. Phase speeds increase with frequency and range from 8 to 50 km d-1. Wavelengths associated with each band are as follows: 460 km for the 100 to 40 d band, 350 km for the 40 to 20 d band, 270 km for the 20 to 10 d band and 230 km for the 10 to 3 d band. The strongest variability is in the 100 to 40 d band. Spatially the 100 to 40 d variability is concentrated to east of the Mississippi Fan, growing and propagating downstream along the eastern portion of the LC. Meanders between 40 and 20 d propagate along the full encompassed length of the LC. Their temporal amplitudes peak at the time of LC eddy detachment and separation. Meanders with shorter periods than 20 d do not always propagate

    The salinity of the open ocean is important for understanding ocean circulation, for understanding energy exchange with the atmosphere and for improving models to predict weather and climate. Passive microwave sensors at L-band (1.4 GHz) operating from aircraft have demonstrated that salinity can be measured with sufficient accuracy (1 psu) to be scientifically meaningful in coastal waters. However, measuring salinity in the open ocean presents unresolved issues largely because of the much greater accuracy (approx. 0.1 psu) required to be scientifically viable. In the summer of 1999 a series of measurements called, The Gulf Stream Experiment, were conducted as part of research at the Goddard Space Flight Center to test the potential for passive microwave remote sensing of salinity in the open ocean. The measurements consisted of a compliment of airborne microwave instruments (radiometers and scatterometer) and ships and drifters for surface truth. The study area was a 200 km by 100 km rectangle about 250 km east of Delaware Bay between the continental shelf waters and north wall of the Gulf Stream. The primary passive instruments were the ESTAR radiometer (L-band, H-pol) and the SLFMR radiometer (L-band, V-pol). In addition, the compliment of instruments on the aircraft included a C-band radiometer (ACMR), an ocean wave scatterometer (ROWS) and an infrared radiometer. A GPS backscatter experiment was also part of the package. These instruments were mounted on the NASA P-3 Orion aircraft. Surface salinity measurements were provided by the RN Cape Henlopen and MN Oleander (thermosalinographs) plus salinity and temperature sensors on three surface drifters deployed from the RN Cape Henopen. The primary experiment period was August 26-September 2, 1999. During this period the salinity field within the study area consisted of a gradient on the order of 2-3 psu in the vicinity of the shelf break and a warm core ring with a gradient of 1-2 psu. Detailed maps were made

    The monitoring of hazardous natural processes In coastal and shelf zone of the gulf of Peter the Great (sea of Japan) in 2012-2013 was made by staff of the Gramberg Institute VNIIOKEANGEOLOGIA . The complex of field researches are: - laser scanning beaches (tachometer Leica HDS 3000); - echosounding underwater coastal slope (sounder-Navigator LCX-37C); - high-frequency acoustic profiling (GeoPulse Subbotom Profilier); - hydromagnetic shooting magnetometer SeaSPY Marine Magnetics; - sonar shooting (complex GEO-CM-MAX); - research of the water column (sounding and sampling); - bottom sampling, including gasgeochemical shooting. The result of this work is the following conclusions: 1.

  14. Is Gulf War Syndrome actually chronic Lyme disease?

    Science.gov (United States)

    Owen, David C

    2005-01-01

    Symptoms of Gulf War Syndrome and chronic Lyme disease are very similar. Lyme disease is a condition which can be difficult to diagnose since one of the main features of the condition, the erythema migrans rash, may be absent or overlooked and serological testing for Lyme disease may be falsely negative. Symptoms of Lyme disease may not became apparent until years after exposure to the causative organism. Military personnel during training in the field are at risk of tick bites and it may be that those who developed Gulf War Syndrome entered the conflict with latent Lyme disease. There has been no systematic examination of Gulf War Syndrome sufferers for chronic Lyme disease and it is hypothesized that chronic Lyme disease has been overlooked as a cause of Gulf War Syndrome. To address this it is suggested that sufferers of Gulf War Syndrome or similar illnesses should be examined by physicians who have experience diagnosing and treating large numbers of patients with Lyme disease.

  15. Gulf Stream density structure and transport during the past millennium.

    Science.gov (United States)

    Lund, David C; Lynch-Stieglitz, Jean; Curry, William B

    2006-11-30

    The Gulf Stream transports approximately 31 Sv (1 Sv = 10(6) m(3) s(-1)) of water and 1.3 x 10(15) W of heat into the North Atlantic ocean. The possibility of abrupt changes in Gulf Stream heat transport is one of the key uncertainties in predictions of climate change for the coming centuries. Given the limited length of the instrumental record, our knowledge of Gulf Stream behaviour on long timescales must rely heavily on information from geologic archives. Here we use foraminifera from a suite of high-resolution sediment cores in the Florida Straits to show that the cross-current density gradient and vertical current shear of the Gulf Stream were systematically lower during the Little Ice Age (ad approximately 1200 to 1850). We also estimate that Little Ice Age volume transport was ten per cent weaker than today's. The timing of reduced flow is consistent with temperature minima in several palaeoclimate records, implying that diminished oceanic heat transport may have contributed to Little Ice Age cooling in the North Atlantic. The interval of low flow also coincides with anomalously high Gulf Stream surface salinity, suggesting a tight linkage between the Atlantic Ocean circulation and hydrologic cycle during the past millennium.

  6. Gulf of Mexico Oceanography Atlas available

    Science.gov (United States)

    The second full-color volume of the Atlas Oceanogáfico del Golfo de México has recently been published by the Grupo de Estudios Oceanográficos of the Instituto de Investigaciones Eléctricas of México (GEO-IIE) (see Eos, Feb. 20, 1990, for announcement of volume 1). This second of an eight-volume series describes the hydrography, baroclinic flows and transports, water masses distributions, and the kinematic properties of anticyclonic-cyclonic ring pairs (modons) of the central and western Gulf of Mexico (26°-20°40‧N, 97°40‧-93°W). The data presented and analyzed in this volume were collected during the Argos 86-1 oceanographic cruise conducted by the GEO-IIE aboard the R/V Justo Sierra during October and November 1986. Authors of the volume are Víctor M. V. Vidal, Francisco V. Vidal, and Abel Hernández. It has 16 chapters in 715 pages, including 248 full-page color plates and 35 tables.

  7. 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.

    Beach ridge plains on four sides of the Gulf of Mexico produced a new, better sea level history for late Holocene time: St. Vincent Island, Florida panhandle; Sanibel Island, lower peninsula of Florida; Mesa del Gavilan, east of Brownsville, Texas; and Isla del Carmen, in the state of Campeche, Mexico. On St. Vincent Island there are more than 300 data points (elevation and relative age), each taken from a beach ridge or a swale. These ridges and swales can be grouped in sets; some sets stand high, and some are low. Their boundaries mark rises and drops of sea level. The St. Vincent Island data fall in a continuous time sequence. The types of data available on and adjacent to this island are topographic (plane-table work), sedimentological (high-precision grain size parameters), photographic (air photos), and pedologic. All of these data agree in meaning, as far as sea level history is concerned. They provide a record of changes, both up and down, in the range of about 1 m to perhaps as much as 3-4 m. Three rises and two drops in the last 6,000 years are obvious. Changes as small as 10-50 cm probably cannot be detected by the methods at hand, but it is highly unlikely, with hundreds of data points in one small study area, that major changes (1 m or more) have been overlooked. The latest change was a rise, about 800 years ago.

    Flatern, R. von

    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.

    1978-01-01

    Both quasi-stationary and dynamic departures from the marine geoid were successfully detected using altitude measurements from the GEOS-3 radar altimeter. The quasi-stationary departures are observed either as elevation changes in single pass profiles across the Gulf Stream or at the crowding of contour lines at the western and northern areas of topographic maps generated using altimeter data spanning one month or longer. Dynamic features such as current meandering and spawned eddies can be monitored by comparing monthly mean maps. Comparison of altimeter inferred eddies with IR detected thermal rings indicates agreement of the two techniques. Estimates of current velocity are made using derived slope estimates in conjunction with the geostrophic equation.

    Pharmaceutical industry now accept the worlds ocean which contains a vast array of organisms with unique biological properties, as a major frontier for medical investigation. Bioactive compounds with different modes of action, such as, antiproliferative, antioxidant, antimicrotubule, have been isolated from marine sources, specifically macro and micro algae, and cyanobacteria. The aim of this work was to investigate antimicrobial and cytotoxic activities of the extracts of marine macro algae Ulva flexuosa, Padina antillarum and Padina boergeseni from the northern coasts of the Persian Gulf, Qeshm Island, Iran, against three cell lines including MCF7, HeLa and Vero, as well as their inhibitory effects against a wide array (i.e. n = 11) of pathogenic bacteria and fungi. Antimicrobial activity of the marine macro algal extracts was assessed using a disc diffusion method; an MTT cytotoxicity assay was employed to test the effects of the extracts on each cancer cell line. The algal extracts showed considerable antimicrobial activity against the majority of the tested bacteria and fungi. Both ethyl acetate and methanol extracts at the highest concentration (100 µg/ml) caused cell death, with the IC50 values calculated for each cell type and each algal extracts. Results are exhibited a higher decrease in the viability of the cells treated at the highest concentration of marine macro algal ethyl acetate extracts compared to the methanol extracts (78.9 % death in Vero cells by ethyl acetate extracts from U. flexuosa). Despite, the ethyl acetate extracts with lower dose- response of cells, exhibited better cytotoxic activity than methanol extracts (IC50: 55.26 μg/ml in Vero cells by ethyl acetate extracts from U. flexuosa). Based on the findings, it is concluded that the marine macro algal extracts from the Persian Gulf possess antibacterial and cytotoxic potential, which could be considered for future applications in medicine and identifying novel drugs from the

    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.

    Full Text Available Abstract Background Since 1993, many studies on the health of Persian Gulf War veterans (PGWVs have been undertaken. Some authors have concluded that an association exists between Gulf War service and reported infertility or miscarriage, but that effects on PGWV's children were limited. The present study's objective was to describe the reproductive outcome and health of offspring of French Gulf War veterans. Methods The French Study on the Persian Gulf War (PGW and its Health Consequences is an exhaustive cross-sectional study on all French PGWVs conducted from 2002 to 2004. Data were collected by postal self-administered questionnaire. A case-control study nested in this cohort was conducted to evaluate the link between PGW-related exposures and fathering a child with a birth defect. Results In the present study, 9% of the 5,666 Gulf veterans who participated reported fertility disorders, and 12% of male veterans reported at least one miscarriage among their partners after the PGW. Overall, 4.2% of fathers reported at least one child with a birth defect conceived after the mission. No PGW-related exposure was associated with any birth defect in children fathered after the PGW mission. Concerning the reported health of children born after the PGW, 1.0% of children presented a pre-term delivery and 2.7% a birth defect. The main birth defects reported were musculoskeletal malformations (0.5% and urinary system malformations (0.3%. Birth defect incidence in PGWV children conceived after the mission was similar to birth defect incidence described by the Paris Registry of Congenital Malformations, except for Down syndrome (PGWV children incidence was lower than Registry incidence. Conclusion This study did not highlight a high frequency of fertility disorders or miscarriage among French PGW veterans. We found no evidence for a link between paternal exposure during the Gulf War and increased risk of birth defects among French PGWV children.

    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.

    The Persian Gulf is known as the westernmost distribution limit for sea snakes, except for Hydrophis platurus (Linnaeus, 1766) that reaches southeastern Africa. Previous identification guides for sea snakes of the Persian Gulf and its adjacent waters in the Gulf of Oman were based on old data and confined mostly to written descriptions. Therefore, a series of field surveys were carried out in 2013 and 2014 through Iranian coastal waters of both gulfs to provide a comprehensive sampling of sea snakes in the area. This paper presents an illustrated and updated checklist and identification tool for sea snakes in the Persian Gulf and Gulf of Oman, which are based on new material and a review of the literature. This checklist includes ten species of marine hydrophiines, of which one, Microcephalophis cantoris (Günther, 1864), is a new record for the area. All specimens examined herein are deposited and available at the Zoological Museum of Shahid Bahonar University of Kerman, Kerman province, Iran.

    The Gulf cooperation council (GCC) region is considered as "Emerging market" for pharmaceutical export and bilateral trade. The understanding of the regulatory requirements of this region can be beneficial for pharmaceutical export. Some incidents of the year 2008-09, like recession or economic slowdown in highly well-off and regulated market of the EU and US, raised the demand for alternate destinations for business. The regulations of Gulf countries are encouraging the import of quality generic products, which can be good news to the Indian drug manufacturers.

    The sea level differences between the Sargasso Sea and the slope waters across the Gulf Stream region, averaged between 73 and 61 deg W, and the comparable areas across the Kuroshio extension region, averaged between 143 and 156 deg E, were estimated using the Geosat altimeter data obtained between November 1986 and December 1988. The sea-level differences between the two regions showed a strong correlation between the northwest Atlantic and Pacific, dominated by annual cycles that peak in late-September to mid-October, with about 9 cm (the Gulf Stream region) and about 6.9 cm (Kuroshio region) amplitudes.

    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.

    Security analysis of communication protocols is a slippery business; many “secure” protocols later turn out to be insecure. Among many, two complains are more frequent: inadequate definition of security and unstated assumptions in the security model. In our experience, one principal cause...... 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. A binding sequence, roughly speaking, is the only required security property of an authentication protocol. All other...

    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.

  10. Demarcation of Security in Authentication Protocols

    DEFF Research Database (Denmark)

    Ahmed, Naveed; Jensen, Christian D.

    2011-01-01

    Security analysis of communication protocols is a slippery business; many “secure” protocols later turn out to be insecure. 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. A binding sequence, roughly speaking, is the only required security property of an authentication protocol. All other...

  11. Crustal Deformation in the Southwestern Gulf of Mexico: Underthrusting of the Gulf of Mexico beneath Tehuantepec

    An array of 45 broad band sensors were installed along the Isthmus of Tehuantepec in southeastern. This experiment, called VEOX, was implemented on August 2007 to March 2009. Data were registered continuously during the whole period. In order to search in the seismic records of the data obtained for crustal events in the Isthmus of Tehuantepec, To this purpose, an STA/LTA algorithm was designed to detect earthquakes with S-P times indicating they occurred close the seismic stations, at crustal or upper mantle depths. During the 18 months that the experiment lasted, about 40 crustal earthquakes were recorded in more than three stations, allowing us to determine a hypo central location. All earthquakes occurring at depths greater than 120 km, within the subjected slab, were discarded. The majority of this crustal or upper mantle activity occurred in the northern part of the Isthmus, along the coast of the Gulf of Mexico or just inland from it. No velocity model exists in the area. Therefore, we tested three different velocity models, including one obtained in an adjacent region and based on seismic refraction data. One of these three models rendered the more stable solutions and smaller errors in the hypocentral locations and was used as the local seismic velocity model. In order to improve the quality of the locations, we experimented using a double difference hypocentral algorithm (HYPODD). There was no noticeable improvement in the quality of the hypocenters using this technique. The best located events suggest a southwestern-dipping zone of seismic seismicity, deepening from the Gulf of Mexico towards the interior of the Isthmus of Tehuantepec. The focal mechanisms of the earthquakes indicate the maximum axis of compresion (P axis) is oriented nearly horizontally and in a southwest-northeast direction. These mechanisms are similar to those observed for earthquakes previously studied in the region on the basis of teleseismic data, such as the Mw 6.9, 29 August

  12. Characterization of Gulf sturgeon diel and seasonal activity in the Pensacola Bay system, Florida

    We assess temporal and spatial distribution and diel variability in activity of Gulf of Mexico sturgeon Acipenser oxyrinchus desotoi in the Pensacola Bay system, Florida, using stationary ultrasonic telemetry. Gulf of Mexico sturgeon (n = 54) migrated through the bay system in fall to wintering areas in the Gulf of Mexico and Santa Rosa Sound. In spring, sturgeon migrated back through the bay system to summering habitats in rivers. Gulf of Mexico sturgeon use East Bay and Escambia Bay primarily as migration routes between riverine areas used in spring and summer and the Gulf of Mexico used in winter. North Central Pensacola Bay was not routinely frequented. Gulf of Mexico sturgeon used specific areas within the Pensacola Bay system in summer and winter not previously documented as essential sturgeon habitat. Areas in southeastern Pensacola were used heavily during winter by a portion of the population. Gulf of Mexico sturgeon also exhibited long-term winter residency in Santa Rosa Sound. Interestingly, an area in northeastern Escambia Bay supported Gulf of Mexico sturgeon in summer. This observation was unexpected; however, the identification of Gulf of Mexico sturgeon in this area at this time has important ecological and management implications. Gulf of Mexico sturgeon exhibited a strong diel activity pattern. Gulf of Mexico sturgeon were more active at night than during day in all seasons but summer. The use of prepositioned arrays of acoustic receivers not only provides continuous data within a defined area, but provides insights into nocturnal behavior not previously examined.

    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. This sensor has the potential to make significant contributions in measuring sub-aerial and submarine coastal topography within cross-environmental surveys. Elevation measurements were collected over the survey area using

    The offshore pipeline network in the U.S. Gulf of Mexico is the largest and most transparent system in the world. A review of deepwater projects in the region provides insight into construction cost and installation methods and the evolution of contract strategies. Pipeline projects are identified as export systems, infield flowline systems, and combined export and infield systems, and three dozen deepwater pipeline installations from 1980-2014 are described based on OTC/SPE industry publications and press release data. Export lines and infield flowlines are equally represented and many projects used a combination of J-lay, S-lay and reel methods with rigid steel, flexible line, and pipe-in-pipe systems. The average 2014 inflation-adjusted cost for pipeline projects based on OTC/SPE publications was 2.76 million/mi and ranged from 520 000/mi to 12.94 million/mi. High cost pipelines tend to be short segments or specialized pipeline. Excluding the two cost endpoints, the majority of projects ranged from 1 to 6 million/mi. The average inflation-adjusted cost to install deepwater pipelines in the U.S. Gulf of Mexico based on available public data is estimated at 3.1 million/mi.

    Full Text Available A female green turtle was sighted at Pamban along the Gulf of Mannar just after the nesting on the beach on 15th January 2011. Morphometric measurements of the turtle were taken and data suggests that this individual is adult. A total number of laid eggs were 109. The distance between the nesting site and the high tide line was found to be 7 m. The depth and diameter of the nesting pit was 52 and 16 cm, whereas the mean egg diameter and weight were found to be 44.3 mm and 40.5 g respectively. Pamban coast may also be considered an important place for nesting, because of the continuous mixing of waters of GOM and Palk Bay areas, which in turn create current patterns continuously throughout the year in addition to the monsoon season. Conservation of nesting habitat along Gulf of Mannar will be important to maintain the green turtle population.

    2010-01-01

    After the April 20th explosion aboard the Deepwater Horizon drilling rig in the Gulf of Mexico, the world witnessed one of the worst oil spill catastrophes in global history. In an effort to mitigate the disaster, the U.S. government moved quickly to establish a unified command for responding to the spill. Some of the command's most immediate needs were to track the movement of the surface oil slick, establish a baseline measurement of pre-oil coastal ecosystem conditions, and assess potential air quality and water hazards related to the spill. To help address these needs and assist the Federal response to the disaster, NASA deployed several of its airborne and satellite research sensors to collect an unprecedented amount of remotely-sensed data over the Gulf of Mexico region. Although some of these data were shared with the public via the media, much of the NASA data on the disaster was not well known to the Gulf Coast community. The need existed to inform the general public about these datasets and help improve understanding about how NASA's science research was contributing to oil spill response and recovery. With its extensive experience conducting community-oriented remote sensing projects and close ties to organizations around Gulf of Mexico, the NASA DEVELOP National Program stood in a unique position to meet this need.

    The epidemiology of multiple sclerosis (MS) is rapidly changing in many parts of the world. Based on the Kurtzke classification, the Arabian Gulf Region is located in a low-risk zone for MS; however, recent studies suggest a moderate-to-high prevalence nearby (31-55 MS per 10,0000 individuals), with an increase in incidence in recent years. The relapsing-remitting disease course ratio is 2.5:1 versus the primary progressive type. In a geographic area that was previously associated with low prevalence; the recent high prevalence and fast rising incidence of MS in the gulf countries, encouraged the neurologists of this region to meet in a consensus panel, in order to share our latest findings in terms of MS epidemiology and consent on MS management in the Arabian Gulf. Therefore 20 key opinion leader neurologists and MS experts representing various countries of the Arabian Gulf have met in Dubai on the 2 and 3 February 2012, they shared their latest epidemiological findings, discussed recent MS aspects in the region, and consented on MS management relevantly to this geographic area.

    Gulf of Jakarta is an area of active sedimentation. There exist a wide sediment deposition area on the north coast of Jakarta. Generally, these sediments have not been consolidated, so that the conditions in these area is an important factor to determining liquefaction in these area. Liquefaction may occur because of earthquake that cause loss of strength and stiffness in soils. Analysis of liquefaction potential based from SPT data taken at gulf of Jakarta, include susceptibility rate and the factors that triggering. Liquefaction analysis methods compared with each other to get the factor of safety against liquefaction according to the characteristics of the soil. Liquefaction analysis at surface using susceptibility rating factor (SRF). SRF method controled by factors: history, geology, composition, and groundwater. Each factors have parameters that determine the value of SRF.From the analysis, Gulf of Jakarta has susceptibility rating from liquefaction with SRF value 12 - 35. The value shows that Gulf of Jakarta dominated by area that have susceptibility rating from medium to high. High susceptibility rating from liquefaction concentrated at coast area.

    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 Gulf of Thailand has been a major marine resource for Thai people for a long time. However, recent industrialization and community development have exerted considerable stress on the marine environments and provoked habitat degradation. The following pollution problems in the Gulf have been prioritized and are discussed in details: (1) Untreated municipal and industrial waste water are considered to be the most serious problems of the country due to limited waste water treatment facilities in the area. (2) Eutrophication is an emerging problem in the gulf of Thailand. Fortunately, the major species of phytoplankton that have been reported as the cause of red tide phenomena were non-toxic species such as Noctiluca sp. and Trichodesmium sp. (3) Few problems have been documented from trace metals contamination in the Gulf of Thailand and public health threat from seafood contamination does not appear to be significant yet. (4) Petroleum hydrocarbon residue contamination is not a problem, although a few spills from small oil tankers have been recorded. A rapid decrease in mangrove forest, coral reefs, and fisheries resources due to mismanagement is also discussed.

    Rose, K.

    2014-12-01

    The Gulf of Mexico Data Atlas is an online data discovery and access tool that allows users to browse a growing collection of ecosystem-related datasets visualized as map plates. Thematically, the Atlas includes updated long-term assessments of the physical, biological, environmental, economic and living marine resource characteristics that indicate baseline conditions of the Gulf of Mexico ecosystems. These data are crucial components of integrated ecosystem assessments and modeling and support restoration and monitoring efforts in the Gulf. A multi-agency executive steering committee including members from international, federal, state, and non-governmental organizations was established to guide Atlas development and to contribute data and expertise. The Atlas currently contains over 235 maps in 70 subject areas. Each map plate is accompanied by a descriptive summary authored by a subject matter expert and each data set is fully documented by metadata in Federal Geographic Data Committee (FGDC)-compliant standards. Source data are available in native formats and as web mapping services (WMS). Datasets are also searchable through an accompanying Map Catalog and RSS feed. The Gulf of Mexico Data Atlas is an operational example of the philosophy of leveraging resources among agencies and activities involved in geospatial data as outlined in the US Department of Interior and FGDC "Geospatial Platform Modernization Roadmap v4 - March 2011". We continue to update and add datasets through existing and new partnerships to ensure that the Atlas becomes a truly ecosystem-wide resource.

    Mexico is undergoing an intense process of economic and industrial development with emphasis on the modernization of its infrastructure. The Gulf of Mexico is a vast region displaying numerous elements of infrastructure: ports, airports, dams and hydroelectric plants, thermal and nuclear power plants, marine oil terminals, roads, railways, bridges, pipelines: oil, gas and water, sewage systems. The ``Corrosion Program of the Gulf of Mexico`` is devoted to the analysis, diagnosis and solution of corrosion and deterioration problems of the engineering materials and structures encountered in the Gulf. The results of a recent corrosion investigation of the longest reinforced concrete, seawater bridge assisted in the maintenance and implementation of a plan for the bridge`s rehabilitation. The ``Program`` is linked to a wide network of centers for cooperation in corrosion investigations related to the infrastructure and its protection in Mexico, the USA, Latin America, Europe and Israel. The knowledge and experience gathered will be useful for corrosion control of the infrastructure of the whole country. This paper presents the varied activities of the ``Program`` in research, development, teaching, training and divulgation, to preserve the infrastructure in the Gulf of Mexico.

    Two 12-mile long pipe-in-pipe (PIP) with HT/HP flow lines were recently designed for the Chinook offshore oil field in the Gulf of Mexico. The routes of the flow line of the Chinook crosses continuous mega-furrows at the water depth ranging from 8200 ft to 8800 ft. The design of the temperature and pressure of the flow lines were 250 deg F and 12,684 psi, respectively. The detailed finite element analysis was performed to predict flow line in-place behavior. The strain-based criterion of API RP 1111 was used where stresses were greater than allowable limits of the ASME B31.8 and found to be satisfactory. The fatigue analysis of the spans pipe subjected to Vortex Induced Vibration (VIV) showed the need for VIV mitigation measures. It was decided that the entire length of the flow lines crossing the mega-furrows should be stake. The analysis of the stake fatigue life of the flow lines resulted greater than the required 25 years service life. Further analysis was performed on the PIP system to optimize the centralizer spacing to sufficiently limit the buckling of inner pipe under operation conditions and prevent crushing of the insulation in the annulus. J-lay analysis of the installation determining the amount of the inner pipe pre-tensioning that was required to eliminate locked-in stresses in the inner and outer pipes. (author)

    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.

  2. Symmetric instability in the Gulf Stream

    2013-07-01

    Analyses of wintertime surveys of the Gulf Stream (GS) conducted as part of the CLIvar MOde water Dynamic Experiment (CLIMODE) reveal that water with negative potential vorticity (PV) is commonly found within the surface boundary layer (SBL) of the current. The lowest values of PV are found within the North Wall of the GS on the isopycnal layer occupied by Eighteen Degree Water, suggesting that processes within the GS may contribute to the formation of this low-PV water mass. In spite of large heat loss, the generation of negative PV was primarily attributable to cross-front advection of dense water over light by Ekman flow driven by winds with a down-front component. Beneath a critical depth, the SBL was stably stratified yet the PV remained negative due to the strong baroclinicity of the current, suggesting that the flow was symmetrically unstable. A large eddy simulation configured with forcing and flow parameters based on the observations confirms that the observed structure of the SBL is consistent with the dynamics of symmetric instability (SI) forced by wind and surface cooling. The simulation shows that both strong turbulence and vertical gradients in density, momentum, and tracers coexist in the SBL of symmetrically unstable fronts. SI is a shear instability that draws its energy from geostrophic flows. A parameterization for the rate of kinetic energy (KE) extraction by SI applied to the observations suggests that SI could result in a net dissipation of 33 mW m-2 and 1 mW m-2 for surveys with strong and weak fronts, respectively. The surveys also showed signs of baroclinic instability (BCI) in the SBL, namely thermally direct vertical circulations that advect biomass and PV. The vertical circulation was inferred using the omega equation and used to estimate the rate of release of available potential energy (APE) by BCI. The rate of APE release was found to be comparable in magnitude to the net dissipation associated with SI. This result points to an

  3. Dirac points and line degeneracies in two-dimensional nonsymmorphic photonic crystals

    2016-01-01

    Topological phase transitions, which have fascinated generations of physicists, are always demarcated by gap closures. In this work, we study the topological properties of gap closure points, i.e. band degeneracies, in photonic crystal lattices exhibiting nonsymmorphic group symmetries. Despite their relatively esoteric symmetries, such lattice structures are relatively easy to fabricate, and thus experimentally study, in photonic systems. We show that the combination of glide symmetry and time reversal symmetry can protect point degeneracies. Line degeneracies along two high symmetry momenta are, however, only protected by one glide symmetry. By defining a topological winding number for point degeneracies, Dirac points with windings of $\\pm 1,\\ -1,\\ -2$ are found in lattices with $pmg$, $pgg$ and $p4g$ nonsymmorphic group symmetries respectively. More interestingly, the breaking of time reversal symmetry in systems with symmetry groups $pgg$ and $p4g$ yield Chern insulators with nontrivial edge states as sol...

    Along with political, economic, ethical, rehabilitative and military dimensions, psychopathological sequelae of war and terrorism also deserve our attention. The terrorist attack on the World Trade Centre ( W.T.C.) in 2001 and the Gulf War of 1990-91 gave rise to a number of psychiatric disturbances in the population, both adult and children, mainly in the form of Post-traumatic Stress disorder (PTSD). Nearly 75,000 people suffered psychological problems in South Manhattan alone due to that one terrorist attack on the WTC in New York and the Pentagon in Washington. In Gulf War I, morethat 1,00,000 US veterans reported a number of health problems on returning from war, whose claims the concerned government has denied in more than 90% cases. Extensive and comprehensive neurological damage to the brain of Gulf War I veterans has been reported by one study, as has damage to the basal ganglia in another, and Amyotrophic Lateral Sclerosis (ALS) in a third,possibly due to genetic mutations induced by exposure to biological and chemical agents, fumes from burning oil wells, landfills,mustard or other nerve gases. The recent Gulf War will no doubt give rise its own crop of PTSD and related disorders. In a cost-benefitanalysis of the post Gulf War II scenario, the psychopathological effects of war and terrorism should become part of the social audit any civilized society engages in. Enlightened public opinion must become aware of the wider ramifications of war and terrorism so that appropriate action plans can be worked out.

  5. 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.

  18. Holocene coastal carbonates and evaporites of the southern Arabian Gulf and their ancient analogues

    Science.gov (United States)

    Alsharhan, A. S.; Kendall, C. G. St. C.

    2003-06-01

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

    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

    市场经济环境下,经济发展速度急速向前,环境污染事故频繁发生,究其原因,与片面追求经济发展、GDP增长而忽视环境保护有很大关系,同时也突显了环境保护司法手段滞后于经济发展的问题。在面对这些造成巨大经济和环境损失的污染事故时,如何正确使用司法手段进行惩罚与预防是本文试图解决的问题。文章从大连康菲石油污染事件为视角切入,分析其中存在的法律责任承担问题,进而通过对现有环境保护法律规定的梳理,析出环境污染案件涉及的刑民界限,为刑法与民法在市场经济条件下的环境污染案件中如何正确适用找到解决途径,同众学者商榷。%Under the market economy environment and along with the enormous rapidity of economic development , there has been an abrupt increase in environmental pollution accidents , whose frequent occurrence can be largely attributable to the one-sided mindset of pursuing economic development and GDP growth while ignoring environmen -tal protection .Meanwhile , the frequent occurrence of such accidents also highlight the fact that our legal means of environmental protection and environmental jurisprudence still lags behind fast economic development .In the face of these environmental pollution accidents causing huge economic losses , the crux of the matter is how to correctly use legal means to punish the perpetrators and prevent such accidents .Exemplified by a legal case involving marine oil pollution in Dalian , this paper aims to ascertain the legal liability in pollution cases and attempts a demarcation of criminal law invocation and that of civil law in dealing with such cases so as to come up with effective solutions to environmental pollution legally under the market-based economic conditions .

    “混杂性”是当今文化理论研究的热点,是后殖民主义理论的关键词。混杂性本为生物学术语,在十九世纪殖民种族主义话语中,沾染了负面的种族与文化内涵。法农等反殖民族知识分子批判了种族主义的混杂观。至二十世纪八、九十年代,混杂性的内涵得到了进一步的发展。萨义德强调了文化混杂性的普遍存在,驳斥了帝国主义与民族主义的文化本质主义与文化纯粹观。霍米•巴巴从语言与文化层面论述了混杂性的颠覆力与能动性,建构了混杂性理论体系。“混杂性”概念在后殖民文化语境中的植入与内涵衍变,反映出不同的意识形态理念。%Hybridity is a hotspot in current culture studies as well as a key term in postcolonialism. Hybridity is a biological term in origin. It is contaminated with negative racial and cultural connotation in the nineteenth century colonial racist discourse. Fanon and other anti-colonial intellectuals criticize the racial connotation of hybridity. In 1980s and 1990s, there is further connotative development of hybridity. Said emphasizes permeating existence of cultural hybridity to refute imperialist and nationalist concept of cultural purity and essentialism. Homi Bhabha explores the subversive and initiative nature of hybridity from language and cultural perspectives and constructs the theory of hybridity. Analyzes the development of demarcation and connotation of hybridity in postcolonial cultural context from historical dimension associating with different ideologies, which shows that hybridity should be studied dialectically and context-specifically.

    The Gulf of Bothnia has variably played host to the main ice divide of the Fennoscandian ice sheet, ice stream onset, trunk and retreat zones, marine ice sheet decay into the large proglacial Baltic Ice Lake, and the subsequent development of an 'inland' marine basin. It is likely to have acted as both source and depocentre for the delivery of ice, water and sediment in both subglacial and ice-marginal domains. These domains and dynamics have been largely inferred from terrestrial, peripheral evidence. The submerged terrain has been little investigated and its glacial geological archives are virtually unknown. In recent years large swathes of high resolution multibeam echo-sounding data (5-10 metre grid cells) from the Baltic Sea and Gulf of Bothnia have been collected for the Swedish Maritime Administration. These data reveal, with unprecedented clarity, glacial landforms associated with the flow and retreat of ice in these basins. Multiple generations of glacial lineations associated with Baltic and Finnish ice streams are resolved, and indicate their shifting geometry and evolving dynamics. Grounding line deposits at a variety of scales allow us to characterise the style and possible rates of retreat. Our data further offer a detailed view of a dynamic subglacial hydrological system on a sediment substrate: its locally varying patterns of incision and sediment deposition, the extent and connectivity of channelised networks, and the intimate relationship between meltwater landforms, ice-marginal deposits and subglacial bedforms. Here we present these data and explore some of their implications for processes of landform creation, large-scale sediment redistribution in the Bothnian and Baltic basins, the coupling between the glacial hydrological system and ice flow/retreat dynamics, and the regional palaeo-ice sheet history.

    Geometric shapes have been suggested to be found in malignant melanomas. We have observed a number of melanomas presenting with linear and incomplete angulated figures. To verify the assumption that geometric shapes, a linear border and/or incomplete angulated figures may indicate a potential melanoma. Patients with surgically removed melanocytic lesions were admitted to the study. We evaluated the presence of a sharp linear demarcation, the presence of contiguous lines resulting in the formation of angle/s and the presence of complete geometric figure. We distinguished the obtained results into melanoma and benign melanocytic naevi. A total of 471 melanomas and 1979 melanocytic naevi were collected. Linear borders, angles and geometric figures were observed in 42 melanomas and in 75 benign melanocytic naevi. Angles with incomplete geometric configuration were observed in 21 melanomas and in 37 benign naevi (21/471 vs. 37/1979, 4.24% vs. 1.87%; P geometrical figures in 12 melanomas and 17 naevi (12/471 vs. 17/1979, 2.54% vs. 0.85%; P geometrical configurations might indicate a suspect melanoma. Only sharp linear demarcation of the lesion do not seem to be significantly associated with melanoma suspicion. © 2014 European Academy of Dermatology and Venereology.

    Badan-Dangon, Antoine; Lavin, Miguel F.; Hendershott, Myrl C.

    The circulation of the Gulf of California has long been of scientific interest. The first hydrographic expedition there was in 1889 [Roden and Groves, 1959], followed half a century later by Sverdrup's cruise on the R/V E.W. Scripps [Suerdrup, 1941] in February and March of 1939. Since then, the Gulfs circulation has been the subject of active research [Alvarez-Boirego, 1983]. During the 1980s, scientists at CICESE and at the Scripps Institution of Oceanography designed a cooperative effort, the Pichicuco project, to investigate some of the notable physical oceanographic features of the Gulf.The Gulf of California is a marginal sea close to 1500 km long and about 200 km wide, oriented northwest to southeast, between the peninsula of Baja California and western continental Mexico. It consists of a succession of basins that shoal progressively from about 3500 m at the mouth, where the Gulf connects with the Pacific Ocean, to just over 2000 m in the central Guaymas Basin. In contrast, the far northern Gulf is a continental shelf sea whose depth exceeds 200 m only in a few small basins. The Gulf's circulation is profoundly influenced by processes taking place at the narrows that connect Guaymas Basin to the northern Gulf between 28°N and 29°N (see Figure 1). These are a sequence of channels, each about 15 km wide, between San Lorenzo, San Esteban, and Tiburón islands, which reduce the effective cross section of the Gulf to about 2.25×106m2. The westernmost connection, close to Baja California, is the Ballenas-Salsipuedes (hereafter Ballenas) channel, whose depth exceeds 1600 m in its central part. It is bounded partially to the north by a lateral constriction with a maximum depth of 600 m, near the northern extreme of Angel de la Guarda island, and to the east by a ridge from which rise Angel de la Guarda, San Lorenzo, and other smaller islands. This ridge extends underwater about 20 km to the southeast from San Lorenzo into Guaymas Basin, where it forms the

    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

    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.

    2013-07-30

    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.

    2006-09-01

    Full Text Available Abstract Background Veterans of the Persian Gulf War of 1991 have reported a range of adverse health symptoms. This systematic review aims to identify all studies that have compared the prevalence of symptoms of pain in veterans of the Gulf War to that in a non-Gulf military comparison group, and to determine whether Gulf War veterans are at increased risk of reporting pain. Methods Studies published between January 1990 and May 2004 were identified by searching a large number of electronic databases. Reference lists and websites were also searched and key researchers were contacted. Studies were included if they reported the prevalence of any symptom or condition that included the word "pain" in Gulf War veterans and in a comparison group of non-Gulf veterans. 2401 abstracts were independently reviewed by two authors. Results Twenty studies fulfilled the inclusion criteria. Five main sites of pain were identified (muscle, joint, chest/heart, back and abdominal pain and separate meta-analyses were performed to summarise the results related to each site. A greater proportion of Gulf veterans reported symptoms at each site of pain when compared to a non-Gulf military group. Gulf deployment was most strongly associated with abdominal pain, with Gulf veterans being more than three times more likely to report such pain than a comparison group (OR 3.23; 95%CI 2.31–4.51. Statistical heterogeneity between study estimates was significant, probably due to variation in measured periods of prevalence and symptom measurement methods. Conclusion A higher proportion of veterans of the Persian Gulf War of 1991 reported symptoms of pain than military comparison groups. This is consistent with previously demonstrated increased reporting of more general symptoms (fatigue, multiple chemical sensitivity, post traumatic stress disorder in these veterans compared with non-Gulf military groups. However, the primary studies were heterogeneous and varied greatly in

    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.

    Since their introduction to the Gulf of Mexico in September 1985, downhole steerable motor systems have been widely recognized for making major contributions to improved directional and horizontal drilling efficiency as well as the overall advancement of drilling technology. Some sources estimate this advanced technology can improve overall drilling productivity by 50 percent. Others foresee the day when future generations of the current systems will replace the rotary table as the primary drive mechanisms for the bit. While the technological issues are coming into better focus, less visible are the ripple effects of this innovation upon the market participants who supply traditional products and services complimentary to the drilling process. The purpose of this article is to provide an objective evaluation of the performance statistics of steerable motor systems to date in the Gulf of Mexico, thereby allowing for a greater understanding of the future market conditions that may develop with this emerging technology.

    Global warming due to the increasing concentration of greenhouse gases has become a great concern and has been linked to increased hurricane activity associated with higher sea surface temperatures with conflicting views. Our observational results based on long term trends of sea surface temperatures reveal that the anomaly reached a record 0.8 C in the Gulf of Mexico in August 2005 as compared to previous years and may have been responsible for the intensification of the devastating Hurricane Katrina into a category 5 hurricane that hit the Southern coast of United States severely impacting the low lying city of New Orleans and the surrounding areas. In most intensifying storms, air-sea interaction is the major contributing factor and here we show how air-sea interactions might have affected Katrinas rapid intensification in the Gulf.

    In the second part of this two-part article on marginal production in the Gulf of Mexico, we estimate the number of committed assets in water depth less than 1000 ft that are expected to be marginal over a 60-year time horizon. We compute the expected quantity and value of the production and gross revenue streams of the gulf's committed asset inventory circa. January 2007 using a probabilistic model framework. Cumulative hydrocarbon production from the producing inventory is estimated to be 1056 MMbbl oil and 13.3 Tcf gas. Marginal production from the committed asset inventory is expected to contribute 4.1% of total oil production and 5.4% of gas production. A meta-evaluation procedure is adapted to present the results of sensitivity analysis. Model results are discussed along with a description of the model framework and limitations of the analysis.

    Shortly after the discovery of chemosynthetic ecosystems at deep-sea hydrothermal vents, similar ecosystems were found at cold seeps in the Gulf of Mexico. Over the past two decades, these sites have become model systems for understanding the physiology of the symbiont-containing megafauna and the ecology of seep communities worldwide. Symbiont-containing bi-valves and siboglinid polychaetes dominate the communities, including five bathymodiolin mussel species and six vestimentiferan (siboglinid polychaete) species in the Gulf of Mexico. The mussels include the first described examples of methanotrophic symbiosis and dual methanotrophic/thiotrophic symbiosis. Studies with the vestimentiferans have demonstrated their potential for extreme longevity and their ability to use posterior structures for subsurface exchange of dissolved metabolites. Ecological investigations have demonstrated that the vestimentiferans function as ecosystem engineers and identified a community succession sequence from a specialized high-biomass endemic community to a low-biomass community of background fauna over the life of a hydrocarbon seep site.

    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

    We calculated input of organic carbon to the unproductive, brackish water basin of the Gulf of Bothnia from rivers, point sources and the atmosphere. We also calculated the net exchange of organic carbon between the Gulf of Bothnia and the adjacent marine system, the Baltic Proper. We compared the input with sinks for organic carbon; permanent incorporation in sediments and mineralization and subsequent evasion of CO 2 to the atmosphere. The major fluxes were riverine input (1500 Gg C year - 1 ), exchange with the Baltic Proper (depending on which of several possible DOC concentration differences between the basins that was used in the calculation, the flux varied between an outflow of 466 and an input of 950 Gg C year - 1), sediment burial (1100 Gg C year - 1 ) and evasion to the atmosphere (3610 Gg C year - 1 ). The largest single net flux was the emission of CO 2 to the atmosphere, mainly caused by bacterial mineralization of organic carbon. Input and output did not match in our budget which we ascribe uncertainties in the calculation of the exchange of organic carbon between the Gulf of Bothnia and the Baltic Proper, and the fact that CO 2 emission, which in our calculation represented 1 year (2002) may have been overestimated in comparison with long-term means. We conclude that net heterotrophy of the Gulf of Bothnia was due to input of organic carbon from both the catchment and from the Baltic Proper and that the future degree of net heterotrophy will be sensible to both catchment export of organic carbon and to the ongoing eutrophication of the Baltic Proper.

    2008-01-01

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

  15. Gulf stream: velocity fluctuations during the late cenozoic.

    Science.gov (United States)

    Kaneps, A G

    1979-04-20

    Biostratigraphic analysis of seven piston cores from the southeastern Blake Plateau suggests that the upper Miocene to Recent sedimentary section at this location represents a history of deposition of calcareous ooze alternating with current-induced nondeposition or erosion. This record is primarily a result of long-term fluctuations in the velocity of the western boundary current or Gulf Stream, which sweeps the plateau. High-velocity phases of this current system, as signaled by hiatuses in the section, lie within the time limits 4.8 to 6.1, 3.9 to 4.4, 2.3 to 2.9, and 0 to 1.5 million years before present (B.P.). These time intervals are coeval with dated episodes of climatic decline and glaciation. The most intense acceleration of the Gulf Stream, as indicated by deep erosion of the Blake Plateau, occurred in the latest Miocene to earliest Pliocene (4.8 to 6.1 million years B.P.) in conjunction with a major expansion of the Antarctic ice cap. Subsequent accelerations of the Gulf Stream coincide with early Pliocene cooling in the Southern Hemisphere, worldwide expansion of high-altitude-high-latitude glaciers in the late Pliocene, and the classical glaciations of the Pleistocene. An additional, protracted increase in the average velocity of the Gulf Stream, which began in the late Miocene and culminated in the mid-Pliocene (about 3.8 million years B.P.), can be attributed to the gradual emergence of the Central American isthmus.

    During 1975 several shipboard expendable bathythermograph surveys plus satellite infrared imagery provided a nearly synoptic view of the distribution and number of Gulf Stream rings in the western North Atlantic. Twelve rings were identified; nine were cyclonic (cold core) rings and three were anticyclonic (warm core) rings. This is the largest number of rings ever observed during a short period of time (4 months). Evidence suggests that the mean movement of these rings was southwestward.

    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.

  11. [A biogeochemical model for the Gulf of Nicoya, Costa Rica].

    2007-03-01

    In agreement with the Broecker and Penn two-boxes model, I generated a biogeochemical balance model for the Gulf of Nicoya (Guanacaste, Costa Rica) using two nutrient reservoirs: surface water and deep water. The mixing zone was located at a depth of 20 m. There is a balance between surface waters descending to the bottom and upwelling waters that carry nutrients and other chemical elements to the surface. The main source of nitrogen (nitrate), was the outlet of the Tempisque and Tárcoles rivers. The Gulf of Nicoya is a net source of Dissolved Inorganic Nitrogen (DIN) with an availability rate of 87 x 10(3) mol day(-1) in the dry season and 3044 x 10(3) mol day(-1)in the rainy season. Dissolved Inorganic Phosphate (DIP) was estimated in 27 mol day(-1) in the dry season and 207 mol day(-1) in the rainy season. The dynamics of these biolimited nutrients, in relation to runoff seasonal variations, fits the biological processes reported for the gulf, for example, for variations in primary productivity levels, and maturity and reproduction seasons for species with short and long life cycles.

  13. Effects of the Gulf Stream on ocean waves

    Science.gov (United States)

    Holthuijsen, L. H.; Tolman, H. L.

    1991-01-01

    In the present study a third-generation numerical wave model is used to study effects of a straight Gulf Stream ring on ocean waves in swell and storm conditions. The model accounts for all relevant processes of propagation, generation, and dissipation of the waves (including current effects) without imposing a priori restraints on the spectral development of the waves. The dominating mechanism affecting the waves appears to be current-induced refraction even though the short-crestedness of the incoming waves tends to mask its effects (also in swell conditions). Depending on wind and wave conditions, refraction may trap locally generated waves in the straight Gulf Stream or it may reflect wave energy back to the open ocean. In the Gulf Stream ring, refraction induces a considerable variation in significant wave height and short-crestedness, but it hardly affects the mean wave direction. In storm conditions the processes of generation and dissipation are considerably enhanced in countercurrent situations and reduced following-current situations.

    Full Text Available Gulf of Martaban is located at the north of Andaman, and is one of the world most turbid areas. The presence of suspended sediment concentration (SSC in the water body could reduce the underwater transmittance. This study has been conducted to investigate the variation of SSC over the Gulf of Martaban. Remote sensing reflectance (Rrs of 667 nm is used as a proxy to represent the sediment SSC variation over the study area. The data for the period of July 2002 to March 2014 acquired from MODIS Aqua 4 km resolution are used in this study. As a result, there is no obvious yearly variation in the SSC cover area. The SSC variation over this study area is found to be seasonal. High homogenous SSC covers area observably during the northeast (NE monsoon season that occurs from December to January. The sediment cover area could reach the latitude of 15°N that located at the south of the gulf. During southwest (SW monsoon season that occurs from May to September, low and sparse SSC cover area is observed. As a consequence, the area covered by the SSC is higher during the NE monsoon season as compared to the SW monsoon season. Hence, the SSC cover area during the NE monsoon season is greater than the yearly averaged SSC cover area. Meanwhile the SSC cover area during the rainy SW monsoon season is less than the yearly and NE monsoon season.

    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.

    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.

    Cancer is a major health problem in both high income and middle-to-low income countries, and is the second leading cause of death in the world. Although more than a third of cancer could be prevented and another third could be cured if diagnosed early, it remains a huge challenge to health-care systems worldwide. Despite substantial improvements in health services some of the countries in the Gulf region, the burden of non-communicable diseases is a major threat, primarily due to the rapid socioeconomic shifts that have led to unfavourable changes in lifestyle such as increased tobacco use, decreased physical activity, and consumption of unhealthy food. In the Gulf Cooperation Council states (United Arab Emirates, Bahrain, Saudi Arabia, Oman, Qatar, and Kuwait), advanced breast cancer, colorectal cancer, leukaemia, thyroid cancer, and non-Hodgkin lymphomas are the most common cancers affecting younger populations compared with other countries. By contrast with cancer prevalence in developed countries, prostate, lung, and cervical cancers are not among the most common cancers in the Gulf region. In view of the increased cost of cancer management worldwide, integrated approaches between primary, secondary, and tertiary health-care systems with special focus on prevention and early detection is an essential step in the countries' efforts in the fight against cancer.

    Full Text Available In Gulf areas, most of the population more than 50% comprises of people form the other nationalities and hence the doctors in gulf area also belong from the different nationalities. The patient and ndash;physician relationship is inherently unequal given the status differences between clinicians and help-seekers. The multiculturalism / or due to different nationalities raises a lot of problems for doctors as well as the patients and this affect the satisfaction level of the patients. The absence of physician trust on behalf of this issue is considered to be a key mechanism underlying health care disparities. This study have been conducted to Gulf area are from different countries and this may lead to different ways of results in dealing with the patients at the same hospital which affects the patients' satisfaction level. The study have found out that patients' satisfaction level is highly dependent upon the nationality of doctors and similarity of the nationality. This issue can be overcome by training the healthcare professionals in leadership, communication, emotional intelligence and other skills in the hospital to have a higher patient satisfaction and to overcome the barriers that are aroused due to the different nationalities of the doctors. Descriptive research design is selected for this study because of its significance to the studies that will be directed in future and it is utilized to depict the specifications of the population under study.

  19. Molecular signatures for Bacillus species: demarcation of the Bacillus subtilis and Bacillus cereus clades in molecular terms and proposal to limit the placement of new species into the genus Bacillus.

    The genus Bacillus is a phylogenetically incoherent taxon with members of the group lacking a common evolutionary history. Comprising aerobic and anaerobic spore-forming bacteria, no characteristics are known that can distinguish species of this genus from other similar endospore-forming genera. With the availability of complete genomic data from over 30 different species from this group, we have constructed detailed phylogenetic trees to determine the relationships among Bacillus and other closely related taxa. Additionally, we have performed comparative genomic analysis for the determination of molecular markers, in the form of conserved signature indels (CSIs), to assist in the understanding of relationships among species of the genus Bacillus in molecular terms. Based on the analysis, we report here the identification of 11 and 6 CSIs that clearly differentiate a 'Bacillus subtilis clade' and a 'Bacillus cereus clade', respectively, from all other species of the genus Bacillus. No molecular markers were identified that supported a larger clade within this genus. The subtilis and the cereus clades were also the largest observed monophyletic groupings among species from the genus Bacillus in the phylogenetic trees based on 16S rRNA gene sequences and those based upon concatenated sequences for 20 conserved proteins. Thus, the relationships observed among these groups of species through CSIs are independently well supported by phylogenetic analysis. The molecular markers identified in this study provide a reliable means for the reorganization of the currently polyphyletic genus Bacillus into a more evolutionarily consistent set of groups. It is recommended that the genus Bacillus sensu stricto should comprise only the monophyletic subtilis clade that is demarcated by the identified CSIs, with B. subtilis as its type species. Members of the adjoining cereus clade (referred to as the Cereus clade of bacilli), although they are distinct from the subtilis clade, will

    The Gulf of California Bibliography was developed for those interested in marine sciences, with references covering a geographic area from Cabo Corrientes to Cabo San Lucas, northward to the head of the Gulf, at the mouth of the Colorado River. The East Pacific Rise at 21 deg N has been included, since it is important to Gulf researchers. Most references to the terrestrial flora and fauna of the Gulf Islands have been excluded. References were obtained through June 1991 in compiling this B...

    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 Gulf of Cadiz lies offshore of Southwest Iberia and Northwest Morocco, bounded to the West by the Azores-Gibraltar transform and to the East by the Betic-Rif mountain belt. The region is famous for the great 1755 Lisbon earthquake and tsunami. Here the plate boundary between Africa and Eurasia is complex, marked by a broad region of deformation spanning about 200 km in a north-south direction. One of the most striking structures characterizing the Gulf of Cadiz is the presence of a thick tectonically deformed sedimentary wedge, which is interpreted as an accretionary wedge formed by the W to SW migration of the Rif-Betic block. Two types of geodynamic models have been proposed to explain the recent tectonics and formation of this region: those invoking delamination of continental lithosphere beneath the Betic-Rif Alboran Sea region, and those favouring subduction of oceanic lithosphere, with associated roll-back. Numerous marine geophysical surveys were performed in the Gulf of Cadiz area during the last years, many as part of the NEAREST European project. Multi-beam bathymetry and multi-channel seismic (MCS) data were acquired, which help constrain the upper crustal structures. Deep structural maps demonstrate that sediment thicknesses in the central Gulf of Cadiz (beneath the accretionary wedge) reach a maximum of 12-13 km. Additional wide-angle seismic records acquired during the SISMAR experiment (2001) testify to the difficulty of even low-frequency waves to penetrate below this thick sedimentary body. Nevertheless, from the resulting models a 7-to-10-km thick basement is inferred beneath the western and central Gulf, which forms a roughly E-W oriented trough between the thicker (20-30 km) continental crust of SW Iberia and NW Morocco. During the NEAREST-SEIS cruise on the B/O Hesperides (nov. 2008), two wide-angle seismic lines were acquired in the Gulf of Cadiz area using a seismic source composed of seven 1500LL Bolt airguns (4520 in3), shot at 90 s

    In the Gulf of Nicoya on the Pacific Coast of Costa Rica, nutrient rich equatorial subsurface water (ESW) is upwelled in much of the lower gulf. These offshore waters are often regarded as the major source of nutrients to the gulf. However, for most of the year, the ESW has little influence on the nutrient content of the upper gulf, which has a distinct character from the lower gulf. The upper gulf, extending 40 km north of the restriction between Puntarenas Peninsula and San Lucas Island, is bordered primarily by mangrove swamps, is less than 20 m deep, and is less saline than the lower gulf. We surveyed the upper gulf for dissolved inorganic nitrogen, phosphate, silicate, dissolved oxygen, and chlorophyll in November 2000, January and July 2001. All nutrients are more concentrated in the upper gulf during the rainy and transitional seasons than the dry season, significantly so for phosphate and silicate. Throughout the year, nutrients tend to be much more concentrated in the less saline water of the upper gulf. This trend indicates that discharge from the Tempisque River predominantly controls spatial and temporal nutrient variability in the upper gulf. However, nutrient rich ESW, upwelled offshore and mixed to form a mid-temperature intermediate water, may enter the inner gulf to provide an important secondary source of nutrients during the dry season.
