  1. Insular Area energy vulnerability, Puerto Rico, US Virgin Islands. Technical Appendix 1

    Energy Technology Data Exchange (ETDEWEB)

    Stern, M.; Willard, E.E.; Efferding, S. [Ensys Energy & Systems, Inc., Flemington, NJ (United States)

    1994-05-01

    This report was prepared in response to Section 1406 of the Energy Policy Act of 1992 (P.L. 192-486). The Act directed the Department of Energy (DOE) to ``conduct a study of the implications of the unique vulnerabilities of the insular areas to an oil supply disruption,`` and to ``outline how the insular areas shall gain access to vital oil supplies during times of national emergency.`` The Act defines the insular areas to be the US Virgin Islands and Puerto Rico in the Caribbean, and Guam, American Samoa, the Commonwealth of the Northern Mariana Islands (CNMI), and Palau in the Pacific. This report is the analysis of Puerto Rico and the US Virgin Islands. In the study, ``unique vulnerabilities`` were defined as susceptibility to: (1) more frequent or more likely interruptions of oil supplies compared to the mainland, and/or (2) disproportionately larger or more likely economic losses in the event of an oil supply disruption. In order to asses unique vulnerabilities, the study examined in the insular areas` experience during past global disruptions of oil supplies and during local emergencies caused by natural disasters. The effects of several possible future global disruptions and local emergencies were also analyzed. Analyses were based on historical data, simulations using energy and economic models, and interviews with officials in the insular governments and the energy industry.

  19. SRTM Perspective with Landsat Virgin Islands, Carribean

    Science.gov (United States)

    2003-01-01

    St. Thomas, St. John, Tortola, and Virgin Gorda are the four main islands (front to back) of this east-looking view of the U.S. Virgin Islands and British Virgin Islands, along the northeast perimeter of the Caribbean Sea. For this view, a nearly cloud-free Landsat image was draped over elevation data from the Shuttle Radar Topography Mission (SRTM), and shading derived from the SRTM data was added to enhance the topographic expression. Elevation is shown with 1.5x scaled vertical exaggeration. Coral reefs fringe the islands in many locations and appear as very light shades of blue. Tropical vegetation appears green, and developed areas appear in shades of brown and white.As in much of the world, topography is the primary factor in the pattern of land use development in the Virgin Islands. Topography across most of the islands is quite rugged, and although the steep slopes create a scenic setting, they crowd most development into the small areas of low relief terrain, generally along the shoreline. The topographic pattern also affects water supply, wastewater disposal, landfill locations, road construction, and most other features of the development infrastructure. Topography also defines the natural drainage pattern, which is the major consideration in anticipating tropical storm water runoff dangers, as well as the dangers of heightened sediment impacts upon the adjacent coral reefs.Landsat has been providing visible and infrared views of the Earth since 1972. SRTM elevation data matches the 30-meter (98-foot) resolution of most Landsat images and substantially helps in analyzing the large and growing Landsat image archive.Elevation data used in this image were acquired by the Shuttle Radar Topography Mission aboard the Space Shuttle Endeavour, launched on February 11, 2000. The mission used the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar that flew twice on the Space Shuttle Endeavour in 1994. The Shuttle

  13. U.S. Virgin Islands Petroleum Price-Spike Preparation

    Energy Technology Data Exchange (ETDEWEB)

    Johnson, C.

    2012-06-01

    This NREL technical report details a plan for the U.S. Virgin Islands (USVI) to minimize the economic damage caused by major petroleum price increases. The assumptions for this plan are that the USVI will have very little time and money to implement it and that the population will be highly motivated to follow it because of high fuel prices. The plan's success, therefore, is highly dependent on behavior change. This plan was derived largely from a review of the actions taken and behavior changes made by companies and commuters throughout the United States in response to the oil price spike of 2008. Many of these solutions were coordinated by or reported through the 88 local representatives of the U.S. Department of Energy's Clean Cities program. The National Renewable Energy Laboratory provides technical and communications support for the Clean Cities program and therefore serves as a de facto repository of these solutions. This plan is the first publication that has tapped this repository.

  14. Contaminants assessment in the coral reefs of Virgin Islands National Park and Virgin Islands Coral Reef National Monument

    Science.gov (United States)

    Bargar, Timothy A.; Garrison, Virginia H.; Alvarez, David A.; Echols, Kathy

    2013-01-01

    Coral, fish, plankton, and detritus samples were collected from coral reefs in Virgin Islands National Park (VIIS) and Virgin Islands Coral Reef National Monument (VICR) to assess existing contamination levels. Passive water sampling using polar organic chemical integrative samplers (POCIS) and semi-permeable membrane devices found a few emerging pollutants of concern (DEET and galaxolide) and polynuclear aromatic hydrocarbons. Very little persistent organic chemical contamination was detected in the tissue or detritus samples. Detected contaminants were at concentrations below those reported to be harmful to aquatic organisms. Extracts from the POCIS were subjected to the yeast estrogen screen (YES) to assess potential estrogenicity of the contaminant mixture. Results of the YES (estrogen equivalency of 0.17–0.31 ng/L 17-β-estradiol) indicated a low estrogenicity likelihood for contaminants extracted from water. Findings point to low levels of polar and non-polar organic contaminants in the bays sampled within VICR and VIIS.

    2016-01-01

    Solanum conocarpum (Solanaceae) (Marron Bacora) is a rare, dry-forest shrub endemic to the island of St. John, US Virgin Islands, considered for listing under the Endangered Species Act. Given its status as a species of conservation concern, we incorporated environmental characteristics of 3 observed populations and 5 additional known locations into a geographic information system (GIS) analysis to create a habitat-suitability model for the species on the island of St. John. Our model identified 1929.87 ha of highly suitable and moderately suitable habitat. Of these, 1161.20 ha (60.2%) occurred within the boundaries of Virgin Islands National Park. Our model provides spatial information on potential locations for future surveys and restoration sites for this endemic species of the US Virgin Islands.

  17. The Globalization of Small Businesses: The Virgin Islands' Perspective

    Directory of Open Access Journals (Sweden)

    Dana Lewis-Ambrose

    2009-12-01

    Full Text Available The purpose of the study was to examine how globalization has affected the small business sector of the Virgin Islands (BVI. Globalization refers to the extension of production and distribution of goods and services on a vastly greater international scale [10] . Overall, the paper has determined that a legal definition of small businesses should be sought in the form of legislation to provide a legal framework to improve the direction of the sector. In the same vein, the eligibility and classification guidelines should be revisited in an effort to make them more practical in their application to small businesses in the territory. It was also found that the contribution of small businesses within the territory may be undervalued because of limitations to data collection in this sector; thus minimizing the decision making, information sharing and support for the sector. The research used interviews and questionnaires conducted among small business stakeholders within the BVI, to validate this claim. In addition, newspaper and other documentary sources were accessed. On ethical grounds, direct reference to a number of the persons interviewed or surveyed has been avoided.

  19. Autumn monitoring of resident avifauna on Guana Island, British Virgin Islands

    Science.gov (United States)

    Boal, Clint W.; Wunderle, Joseph M.; Arendt, Wayne J.

    2013-01-01

    Although the Caribbean region is considered a biodiversity hotspot and a priority for ecological conservation efforts, little information exists on population trends of West Indian landbirds. We combined avian survey data collected from three studies spanning a 16-year period on a small island with a minimal human presence in the British Virgin Islands. Although abundances varied among surveys, the same species were detected with rare exceptions. Despite stability in species composition, the resident landbirds were variable in their individual detectabilities. Survey detections relatively mirrored net captures for some species, but are quite different for others. We suspect that this is likely due to differences in detectability due to species-specific behaviors mediated by environmental conditions, such as rainfall, during the month or months prior to our surveys. It is difficult to assess the influence of timing or amount of precipitation on bird detections rates among our surveys due to a lack of consistent collection of location-specific weather data in the British Virgin Islands. Our study suggests monitoring efforts conducted in concert with collection of site-specific climate data would facilitate improved interpretation of survey data and a better understanding of avian species response to climate mediated changes.

    These remotely sensed, geographically referenced elevation measurements of Lidar-derived submerged 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), South Florida-Caribbean Network, Miami, FL; and the National Aeronautics and Space Administration (NASA), Wallops Flight Facility, VA. This project provides highly detailed and accurate bathymetric datasets of a portion of the U.S. Virgin Islands, acquired on April 21, 23, and 30, May 2, and June 14 and 17, 2003. 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 EAARL system, and

  7. Tsunami simulations of the 1867 Virgin Island earthquake: Constraints on epicenter location and fault parameters

    Science.gov (United States)

    Barkan, Roy; ten Brink, Uri S.

    2010-01-01

    The 18 November 1867 Virgin Island earthquake and the tsunami that closely followed caused considerable loss of life and damage in several places in the northeast Caribbean region. The earthquake was likely a manifestation of the complex tectonic deformation of the Anegada Passage, which cuts across the Antilles island arc between the Virgin Islands and the Lesser Antilles. In this article, we attempt to characterize the 1867 earthquake with respect to fault orientation, rake, dip, fault dimensions, and first tsunami wave propagating phase, using tsunami simulations that employ high-resolution multibeam bathymetry. In addition, we present new geophysical and geological observations from the region of the suggested earthquake source. Results of our tsunami simulations based on relative amplitude comparison limit the earthquake source to be along the northern wall of the Virgin Islands basin, as suggested by Reid and Taber (1920), or on the carbonate platform north of the basin, and not in the Virgin Islands basin, as commonly assumed. The numerical simulations suggest the 1867 fault was striking 120°–135° and had a mixed normal and left-lateral motion. First propagating wave phase analysis suggests a fault striking 300°–315° is also possible. The best-fitting rupture length was found to be relatively small (50 km), probably indicating the earthquake had a moment magnitude of ∼7.2. Detailed multibeam echo sounder surveys of the Anegada Passage bathymetry between St. Croix and St. Thomas reveal a scarp, which cuts the northern wall of the Virgin Islands basin. High-resolution seismic profiles further indicate it to be a reasonable fault candidate. However, the fault orientation and the orientation of other subparallel faults in the area are more compatible with right-lateral motion. For the other possible source region, no clear disruption in the bathymetry or seismic profiles was found on the carbonate platform north of the basin.

    2013-01-01

    Surveys of juvenile hawksbills around Buck Island Reef National Monument, US Virgin Islands from 1994 to 1999 revealed distributional patterns and resulted in a total of 75 individual hawksbill captures from all years; turtles ranged from 23.2 to 77.7 cm curved carapace length (CCL; mean 42.1 ± 12.3 cm SD). Juveniles concentrated where Zoanthid cover was highest. Length of time between recaptures, or presumed minimum site residency, ranged from 59 to 1,396 days (mean 620.8 ± 402.4 days SD). Growth rates for 23 juveniles ranged from 0.0 to 9.5 cm year−1 (mean 4.1 ± 2.4 cm year−1SD). Annual mean growth rates were non-monotonic, with the largest mean growth rate occurring in the 30–39 cm CCL size class. Gastric lavages indicated that Zoanthids were the primary food source for hawksbills. These results contribute to our understanding of juvenile hawksbill ecology and serve as a baseline for future studies or inventories of hawksbills in the Caribbean.

    St. John, and probably the Cinnamon Bay watershed, has a history of human use dating to 1700 B.C. The most notable impacts, however, occurred from 1730 to 1780 when sugar cane and cotton production peaked on the island. As agriculture was abandoned, the island regenerated in secondary forest, and in 1956, the Virgin Islands National Park was created. From 1983 to 2003...

    Many species of groupers form spawning aggregations, dramatic events where 100s to 1000s of individuals gather annually at specific locations for reproduction. Spawning aggregations are often targeted by local fishermen, making them extremely vulnerable to over fishing.

  3. Age-Ratios and Condition of En Route Migrant Blackpoll Warblers in the British Virgin Islands

    Science.gov (United States)

    Boal, Clint W.

    2014-01-01

    The en route migration ecology of Blackpoll Warblers (Setophaga striata) is poorly understood, yet intriguing. Blackpoll Warblers undertake the longest open water migration of any wood warbler species, traveling from northeastern North America to South America, with the first potential landfall being the West Indies. This migration requires substantial energy reserves and subjects Blackpoll Warblers to unpredictable weather events, which may influence survival. Few studies have examined age ratios or condition of Blackpoll Warblers while the warblers are en route through the Caribbean region. I captured and banded Blackpoll Warblers in the British Virgin Islands over 10 consecutive autumn migrations. Ratios of hatch-year to adult Blackpoll Warblers were variable but averaged lower than the ratios reported at continental departure locations. Average mass of Blackpoll Warblers was less than that reported at continental departure locations, with 26% of adults and 40% of hatch-year birds below the estimated fat free mass; hatch-year birds were consistently in poorer condition than adults. Blackpoll Warblers captured in the British Virgin Islands were also in poorer condition than those reported from the Dominican Republic and Barbados; this may be because of the British Virgin Islands being the first landfall after the transatlantic crossing, whereas Blackpoll Warblers arriving at the other Caribbean study locations may have had opportunities for stopover prior to arrival or have departed from farther south on the continent. However, this suggests that the British Virgin Islands likely provide important stopover habitat as a first landfall location for Blackpoll Warblers arriving from the transatlantic migration route.

  8. Synthetic ultraviolet light filtering chemical contamination of coastal waters of Virgin Islands National Park, St. John, U.S. Virgin Islands

    Science.gov (United States)

    Bargar, Timothy A.; Alvarez, David; Garrison, Virginia H.

    2015-01-01

    Contamination of surface waters by synthetic ultraviolet light (UV) filtering chemicals is a concern for the Virgin Islands National Park (VINP). Discrete water samples were collected from VINP bays to determine UV filter chemical presence in the coastal waters. Spatial distribution and the potential for partitioning between subsurface waters and the sea surface microlayer (SML) were also examined. The UV filter chemicals 4-methylbenzylidene camphor, benzophenone-3, octinoxate, homosalate, and octocrylene were detected at concentrations up to 6073 ng/L (benzophenone-3). Concentrations for benzophenone-3 and homosalate declined exponentially (r2 = 0.86 to 0.98) with distance from the beach. Limited data indicate that some UV filter chemicals may partition to the SML relative to the subsurface waters. Contamination of VINP coastal waters by UV filter chemicals may be a significant issue, but an improved understanding of the temporal and spatial variability of their concentrations would be necessary to better understand the risk they present.

  9. U.S. Virgin Islands Transportation Petroleum Reduction Plan

    Energy Technology Data Exchange (ETDEWEB)

    Johnson, C.

    2011-09-01

    This NREL technical report determines a way for USVI to meet its petroleum reduction goal in the transportation sector. It does so first by estimating current petroleum use and key statistics and characteristics of USVI transportation. It then breaks the goal down into subordinate goals and estimates the petroleum impacts of these goals with a wedge analysis. These goals focus on reducing vehicle miles, improving fuel economy, improving traffic flow, using electric vehicles, using biodiesel and renewable diesel, and using 10% ethanol in gasoline. The final section of the report suggests specific projects to achieve the goals, and ranks the projects according to cost, petroleum reduction, time frame, and popularity.

    2016-01-01

    The Virgin Islands Robotic Telescope is an 0.5m robotic telescope located at the easternmost and southernmost optical observatory in the United States at a latitude of 18.5N and longitude of 65W. The observatory is located on the island of St Thomas in the USVI. Astronomers from the College of Charleston, the US Air Force Academy, and the University of the Virgin Islands collaborate to maintain and operate the facility. The primary scientific focus of the facility is the optical follow-up of high-energy transients though a variety of other science interests are also being pursued including follow-up of candidate extra-solar planets, rotation studies of cool stars, and near-Earth asteroid and space situational awareness studies. The facility also supports a wide-reaching education and outreach program dedicated to raising the level of STEAM engagement and enrichment in the USVI. We detail the characteristics, capabilities, and early results from the observatory. The observatory is growing its staff and science activities and potential topics for collaboration will be discussed.

  11. Constraining Puerto Rico - Virgin Islands microplate internal deformation with two decades of GPS observations

    2011-12-01

    The Puerto Rico - Virgin Island microplate, a crustal block within the deformation region of the Northern Caribbean Plate Boundary Zone has been monitored with campaign and permanent Global Positioning System stations for almost 20 years. Within this time period a total of 37 sites have been used to describe and quantify internal deformation of the plate and estimate elastic strain accumulation along the key geological bounding features. In June 2011, 12 of the 20 sites that comprise the campaign GPS network in Puerto Rico were re-occupied and their results were merged with at least three years of continuous GPS data from the Puerto Rico - Virgin Islands cGPS network. The remaining 8 in PR sites will be reoccupied soon, while sites from the Virgin Islands were last reoccupied in 2007. All data were processed with v5 of GOAII using an APP strategy. Here we present the latest results of the newly computed velocity field of our mixed network in both North America and Caribbean fixed frames employing the latest IGS05 reference frame and updated satellite orbits, earth orientation, and xfiles from JPL. Of particular importance in this study are the results of a three station transect across the Lajas Valley, the most seismically active area on southwestern Puerto Rico. Relative to a fixed velocity for a campaign site on Isla Magueyes in La Parguera, the southernmost site in the Lajas Valley has a residual motion of -4.38±1.39 and 2.41±2.10 mm/yr in the north and east components, respectively. This suggests that there is SSE-directed shortening across a structure located between these two sites. In contrast, sites near Mayagüez are moving toward SW at ˜2 mm/yr relative to La Parguera. These results demonstrate the PRVI block shows small internal deformation in addition to its generally westward rigid block translation relative the stable interior of the Caribbean plate.

  13. Bryophyte colonization history of the virgin volcanic island Surtsey, Iceland

    Directory of Open Access Journals (Sweden)

    G. V. Ingimundardóttir

    2014-08-01

    Full Text Available The island Surtsey was formed in a volcanic eruption south of Iceland in 1963–1967 and has since then been protected and monitored by scientists. The first two moss species were found on Surtsey as early as 1967 and several new bryophyte species were discovered every year until 1973 when regular sampling ended. Systematic bryophyte inventories in a grid of 100 m × 100 m quadrats were made in 1971 and 1972: the number of observed species doubled, with 36 species found in 1971 and 72 species in 1972. Here we report results from an inventory in 2008, when every other of the grid's quadrats were searched for bryophytes. Despite lower sampling intensity than in 1972, distributional expansion and contraction of earlier colonists was revealed as well as the presence of new colonists. A total of 38 species were discovered, 15 of those were not encountered in 1972 and eight had never been reported from Surtsey before (Bryum elegans, Ceratodon heterophyllus, Didymodon rigidulus, Eurhynchium praelongum, Schistidium confertum, S. papillosum, Tortula hoppeana and T. muralis. Habitat loss due to erosion and reduced thermal activity in combination with successional vegetation changes are likely to have played a significant role in the decline of some bryophyte species which were abundant in 1972 (Leptobryum pyriforme, Schistidium apocarpum coll., Funaria hygrometrica, Philonotis spp., Pohlia spp, Schistidium strictum, Sanionia uncinata while others have continued to thrive and expand (e.g. Schistidium maritimum, Racomitrium lanuginosum, R. ericoides, R. fasciculare and Bryum argenteum. Some species (especially Bryum spp. benefit from the formation of new habitats, such as grassland within a gull colony, which was established in 1984. Several newcomers are rarely producing sporophytes on Iceland and are unlikely to have been dispersed by airborne spores. They are more likely to have been introduced to Surtsey by seagulls in the form of vegetative fragments

  14. Non-overlapping distributions of feral sheep (Ovis aries) and Stout Iguanas (Cyclura pinguis) on Guana Island, British Virgin Islands

    Stout Iguanas (Cyclura pinguis) remain one of the most critically endangered reptiles in the world. Factors contributing to that status include habitat loss, predation by introduced species, and competition with introduced herbivores. On Guana Island, British Virgin Islands, the presence of feral sheep (Ovis aries) has been a hypothesized detriment to iguanas. Using motion sensitive cameras, we documented the distribution of feral sheep on Guana Island in 2010. We also quantified the impact of feral sheep on ground vegetation by comparing plant abundance at longterm sheep exclosures and areas where sheep were absent to areas where sheep were present. Finally, we compared sheep distribution to iguana distribution on the island. The co-occurrence of sheep and Stout Iguanas was less than expected, indicating possible competition. Although we detected no difference in vegetative cover between areas where sheep were present and absent, the long-term exclosures showed that the exclusion of sheep allowed the abundance of many plant species to increase. Our data support the hypothesis that feral sheep are altering the abundance of ground-level vegetation and limiting iguana distribution on the island.

  15. A unique coral community in the mangroves of Hurricane Hole, St. John, US Virgin Islands

    Science.gov (United States)

    Rogers, Caroline S.

    2017-01-01

    Corals do not typically thrive in mangrove environments. However, corals are growing on and near the prop roots of red mangrove trees in Hurricane Hole, an area within the Virgin Islands Coral Reef National Monument under the protection of the US National Park Service in St. John, US Virgin Islands. This review summarizes current knowledge of the remarkable biodiversity of this area. Over 30 scleractinian coral species, about the same number as documented to date from nearby coral reefs, grow here. No other mangrove ecosystems in the Caribbean are known to have so many coral species. This area may be a refuge from changing climate, as these corals weathered the severe thermal stress and subsequent disease outbreak that caused major coral loss on the island’s coral reefs in 2005 and 2006. Shading by the red mangrove trees reduces the stress that leads to coral bleaching. Seawater temperatures in these mangroves are more variable than those on the reefs, and some studies have shown that this variability results in corals with a greater resistance to higher temperatures. The diversity of sponges and fish is also high, and a new genus of serpulid worm was recently described. Continuing research may lead to the discovery of more new species.

  16. The Sargassum Frogfish (Histrio histrio Linnaeus) observed in mangroves in St. John, US Virgin Islands

    2010-01-01

    The Sargassum Frogfish (Histrio histrio), the only pelagic member of the frogfish family Antennariidae, is considered an obligate associate of floating mats of the brown algae Sargassum natans and S. fluitans (Adams 1960; Dooley 1972; Pietsch and Grobecker 1987). Between February and April 2010, 20 of these fish were observed in three mangrove-fringed bays in Virgin Islands Coral Reef National Monument, St. John, US Virgin Islands. All of them were clinging to clumps of the red alga Acanthophora spicifera growing on the submerged prop roots of red mangrove trees (Rhizophora mangle) distributed along an estimated total of 2,160 mof shoreline (Fig. 1). All of the fish were at a depth of less than 0.5 meters. Two individuals were seen on one prop root, but the other 18 were solitary. Their estimated standard lengths ranged from about 20 to 100 mm. Littler and Littler (2000, p. 295) published a photograph of one individual in blades of the green alga Ulva lactuca growing on a prop root in Belize. This is the first report of the Sargassum Frogfish living in association with attached algae.

  17. Eastern Caribbean Circulation and Island Mass Effect on St. Croix, US Virgin Islands: A Mechanism for Relatively Consistent Recruitment Patterns.

    Directory of Open Access Journals (Sweden)

    Laurent Marcel Chérubin

    Full Text Available The northeastern Caribbean Sea is under the seasonal influence of the Trade Winds but also of the Orinoco/Amazon freshwater plume. The latter is responsible for intensification of the Caribbean Current in general and of its eddy activity in the northern part of the Caribbean Sea. More importantly, we show in this study that the front of the freshwater plume drives a northward flow that impinges directly on the island of St. Croix in the United States Virgin Islands. The angle of incidence of the incoming flow controls the nature of the wake on both sides and ends of the island, which changes from cyclonic to anticylonic wake flow, with either attached or shed eddies. Using an off-line bio-physical model, we simulated the dispersal and recruitment of an abundant Caribbean coral reef fish, the bluehead wrasse (Thalassoma bifasciatum in the context of the wake flow variability around St. Croix. Our results revealed the role played by the consistent seasonal forcing of the wake flow on the recruitment patterns around the island at the interannual scale. The interannual variability of the timing of arrival and northward penetration of the plume instead controls the nature of the wake, hence the regional spatial recruitment patterns.

    Managing the effects of anthropogenic disturbance on coral reefs is highly dependant on effective strategies to assess degradation and recovery. We used five years of field data in the US Virgin Islands to investigate coral reef response to a potential gradient of stress. We found that the prevalence of old partial mortality, bleaching, and all forms of coral health impairment (a novel category) increased with nearshore anthropogenic processes, such as a five-fold higher rate of clay and silt sedimentation. Other patterns of coral health, such as recent partial mortality, other diseases, and benthic cover, did not respond to this potential gradient of stress or their response could not be resolved at the frequency or scale of monitoring. We suggest that persistent signs of disturbance are more useful to short-term, non-intensive (annual) coral reef assessments, but more intensive (semi-annual) assessments are necessary to resolve patterns of transient signs of coral health impairment.

  9. Late Pleistocene-Holocene geology of the central Virgin Island Platform

    Science.gov (United States)

    Holmes, C.W.; Kindinger, J.L.

    1985-01-01

    Geophysical and sedimentological data collected on the central Virgin Islands insular shelf provide a unique opportunity to investigate carbonate shelf processes in an active tectonic environment. Although complicated by fluctuating sea level during the Quaternary, the sedimentological regimes have been controlled by the tectonic fragmentation of the region. South of St. John, a northeast-southwest intrusive ridge controlled the development of the shallow geology. Profiles across this region, seaward of the ridge, indicate the existence of a buried wave-cut platform. Resting on this eroded surface, at the shelf break, is a reef having a topographic relief of 55 m. This reef, which formed a protective barrier preserving a sequence of lagoonal deposits, has been radiometrically determined to have died ???7000 yrs B.P., coinciding with the death of similar reefs in Florida and on the Island of St. Croix. South of St. Thomas, the strata are horizontal and are bisected by east-west midshelf faults. Truncation of the shelf edge strata, northern drainage, and unconformities on the northern shelf indicate that this block was tilted to the north during the late Pleistocene. This limited reef development to a narrow zone on the southern shelf edge. Geochemical, biological and sedimentological data indicate that the early to mid-Holocene was a time of vigorous shelf sedimentation. This accumulation peaked and abruptly stopped ???1200 yrs B.P., due to continued subsidence. Since this time, most sediment accumulation has been limited to the immediate area around the islands. ?? 1985.

  10. Marine and inland fishes of St. Croix, U. S. Virgin Islands: an annotated checklist

    Science.gov (United States)

    Smith-Vaniz, William F.; Jelks, Howard L.

    2014-01-01

    An historical account is given for the ichthyological research at St. Croix, U. S. Virgin Islands, followed by an annotated list of 544 species of mostly marine shore fishes known or reported from the island to depths of 200 m. Color photographs are included for 103 of these species. Collections made at Buck Island Reef National Monument with the ichthyocide rotenone in 2001 and 2005 increased the known ichthyofauna by about 80 species. The rational for inclusion of each species in the checklist is given, with remarks for those species for which additional documentation or voucher specimens are needed. Reports of species known or presumed to have been based on misidentifications are discussed. Of the total marine fish fauna of the island, 404 species (75%) are restricted to the western Atlantic Ocean, (223 of these species are essentially Caribbean endemics that do not occur south of the Amazon River outflow), and no St. Croix endemic species are known. An additional 17 species (3.2%) also occur at mid-Atlantic islands, 57 species (10.6 %) are limited to both sides of the Atlantic Ocean, and 40 species (7.4%) have circumtropical distributions. The four most species-rich families are the Gobiidae (47 species), Serranidae (groupers and sea basses, 41), Labridae (wrasses and parrotfishes, 31), and Labrisomidae (scaly blennies, 27). Literature reports of Mosquitofish, Gambusia sp., from St. Croix apparently were based on misidentifications of a different introduced poeciliid genus. Four species of the amphidromus goby genus Sicydium occur in St. Croix inland waters, together with three established introduced species (one cichlid and two poeciliids). Also included are one catfish (Ictaluridae) and three sunfishes (Centrarchidae) known only from ponds. The Lionfish, Pterois volitans, the only introduced marine species, was first reported from St. Croix in 2008 and is now common despite control efforts.

    During October 2013, an ocean exploration project took place off the coast of Puerto Rico and the Virgin Islands. This project, a collaborative effort between the Ocean Exploration Trust, the US Geological Survey, the University of Puerto Rico at Mayaguez, the University of Rhode Island, and NOAA, was aimed at exploring regions of the US exclusive economic zone (EEZ) south of the Puerto Rico Trench axis, and north of Mona Island, Puerto Rico, and the US and British Virgin Islands, and portions of the Anegada Passage. The research vessel E/V Nautilus and the Hercules/Argus ROV system were used to expand the multibeam sonar bathymetric data coverage of the region, collect high definition video footage of seafloor features, and to collect biological and geological samples along selected transects. Particular areas of interest for targeted ROV dives included: the region where a large M7.2 1918 earthquake produced a tsunami that struck northwestern corner of Puerto Rico; a transect up the vertical wall of the Mona Rift (4000 to 1500 m depth); transects along the Septentrional fault system; dives in areas of suspected fluid flow through faults, fissures, and offshore Karst systems associated with the tilted carbonate platform north of Puerto Rico; dives in the Anegada Passage at the entry points for surface Atlantic waters that circulate into the Caribbean; and in regions to investigate and date sedimentary features offset by fault motion and potential tsunamigenic landslides. Biological sampling of many deep-sea benthic organisms (including deep water corals) have never been attempted before in this area. These samples are being used to understand more about the diversity, population dynamics, genetics, and habitat connectivity of these communities, and to provide an age constraint for disturbed sedimentary features. Until this cruise, the location and distribution of deep coral habitats in the US Caribbean was largely unknown. The available information on benthic

    The Virgin Islands Robotic Telescope (VIRT) is an 0.5m robotic telescope located at the easternmost and southernmost optical observatory in the United States at a latitude of 18.5N and longitude of 65W. The observatory is located on the island of St Thomas in the United States Virgin Islands (USVI). Astronomers from the College of Charleston, the US Air Force Academy and the University of the Virgin Islands (UVI) collaborate to maintain and operate the facility. Science goals of the facility include optical follow-up of high-energy transients, extra-solar planet observations, and near-Earth asteroid searches. The facility also supports a wide-reaching education and outreach program dedicated to raising the level of STEM engagement and enrichment in the USVI and is a primary research facility for students in UVI's new Physics Degree with a Concentration in Astronomy. The VIRT has begun reacting autonomously to the gamma-ray coordinates network (GCN) alerts in 2017 and, despite the challenges presented to the Caribbean region by hurricanes Irma and Maria, was a participant in the follow-up campaign of GW170817, the first source simultaneously detected in gravitational waves and electromagnetic waves. We detail the robotization and automation of the VIRT, provide an update on its characteristics and capabilities and discuss recent science results from the observatory as well as ongoing progress in the recovery from damage caused by hurricanes Irma and Maria.

    2007-12-01

    It is well established that elevated sea temperatures cause widespread coral bleaching, yet confusion lingers as to what facet of extreme temperatures is most important. Utilizing long-term in situ datasets, we calculated nine thermal stress indices and tested their effectiveness at segregating bleaching years a posteriori for multiple reefs on the Florida Reef Tract. The indices examined represent three aspects of thermal stress: (1) short-term, acute temperature stress; (2) cumulative temperature stress; and (3) temperature variability. Maximum monthly sea surface temperature (SST) and the number of days >30.5 degrees C were the most significant; indicating that cumulative exposure to temperature extremes characterized bleaching years. Bleaching thresholds were warmer for Florida than the Bahamas and St. Croix, US Virgin Islands reflecting differences in seasonal maximum SST. Hind-casts showed that monthly mean SST above a local threshold explained all bleaching years in Florida, the Bahamas, and US Virgin Islands.

    2015-12-01

    Land based sources of pollution have the potential to negatively impact coral reef ecosystems. Many coral systems, including environmentally sensitive marine protected areas, do not have assessments of their chemical contaminant status (magnitude and extent). Without a status assessment, it is impossible to measure change in a system. This study presents surficial sediment data from Coral and Fish Bays (St. John, US Virgin Islands (USVI)). Portions of these bays are included in Virgin Islands National Park, and Virgin Islands Coral Reef National Monument. A suite of analytes (PCBs, PAHs, pesticides, heavy metals, butyltins) was quantified and compared against other regional data and against previously published sediment quality guidelines (SQG). Contamination from toxic contaminants in the system was generally low when compared to other similar studies and potential toxicity thresholds (SQG). Exceptions to this were copper and total chlordane which exceeded the Effects Range Low (ERL) sediment quality guideline, indicating possible sediment toxicity.

    Human activity is contributing increasing noise to marine ecosystems. Recent studies have examined the effects of boat noise on marine fishes, but there is limited understanding of the prevalence of this type of sound source. This investigation tracks vessel noise on three reefs in the US Virgin Islands National Park over four months in 2013. Ambient noise levels ranged from 106 to 129dBrms re 1μPa (100Hz-20kHz). Boat noise occurred in 6-12% of samples. In the presence of boat noise, ambient noise in a low-frequency band (100-1000Hz) increased by >7dB above baseline levels and sound levels were significantly higher. The frequency with the most acoustic energy shifted to a significantly lower frequency when boat noise was present during the day. These results indicate the abundance of boat noise and its overlap with reef organism sound production, raising concern for the communication abilities of these animals.

    Many species of groupers form spawning aggregations, dramatic events where 100s to 1000s of individuals gather annually at specific locations for reproduction. Spawning aggregations are often targeted by local fishermen, making them extremely vulnerable to over fishing. The Red Hind Bank Marine Conservation District located in St. Thomas, United States Virgin Islands, was closed seasonally in 1990 and closed permanently in 1999 to protect an important red hind Epinephelus guttatus spawning site. This study provides some of the first information on the population response of a spawning aggregation located within a marine protected area. Tag-and-release fishing and fish transects were used to evaluate population characteristics and habitat utilization patterns of a red hind spawning aggregation between 1999 and 2004. Compared with studies conducted before the permanent closure, the average size of red hind increased mostly during the seasonal closure period (10 cm over 12 yr), but the maximum total length of male red hind increased by nearly 7 cm following permanent closure. Average density and biomass of spawning red hind increased by over 60% following permanent closure whereas maximum spawning density more than doubled. Information from tag returns indicated that red hind departed the protected area following spawning and migrated 6 to 33 km to a ca. 500 km(2) area. Protection of the spawning aggregation site may have also contributed to an overall increase in the size of red hind caught in the commercial fishery, thus increasing the value of the grouper fishery for local fishermen.

  8. An integrated assessment of electric power resource options in the US Virgin Islands

    As with other island-based, insular power systems, the avoided cost of power for the Water and Power Authority (WAPA) of the US Virgin Islands (USVI) is high relative to that of US mainland electric utilities. First, the need to produce potable water requires that WAPA`s electric generating system operate at efficiency levels lower than would result in the absence of the need to jointly produce water and power. Second, the inability to purchase power from neighboring utilities necessitates higher reserve margins. These two operating conditions suggest that integrated resource planning (IRP) should be especially attractive to WAPA. IRP is a planning paradigm that gives electric utilities more options to choose from when making resource selections and, therefore, generally results in lower costs. Utilities look to the demand side as a source of resources--i.e., demand side management (DSM)--in this planning process. They then select the least-cost mix of resource options. In this study, we take the first steps toward implementing an IRP process in the USVI. Using its existing resource base and the supply and DSM options that it has in the future, we simulated WAPA`s resource selection process over a 20-year planning horizon using SafePlan, an IRP planning model. The results suggest that WAPA can significantly reduce its cost of providing electricity by implementing DSM programs. The cost of generating electricity and the amount of kWh needed can be reduced nearly nine percent by implementing cost-effective DSM programs. Cost and kWh savings are greater under less favorable assumptions about (1) the input costs for generating electricity and (2) other conditions that WAPA will confront in the future. The results also indicate that DSM programs targeted at the residential sector can save, 500 gallons of water annually for participants in the program.

  9. Degradation of marine ecosystems and decline of fishery resources in marine protected areas in the US Virgin Islands

    The large number of marine protected areas (MPAs) in the Caribbean (over 100) gives a misleading impression of the amount of protection the reefs and other marine resources in this region are receiving. This review synthesizes information on marine resources in two of the first MPAs established in the USA, namely Virgin Islands National Park (1962) and Buck Island Reef National Monument (1961), and provides compelling evidence that greater protection is needed, based on data from some of the longest running research projects on coral reefs, reef fish assemblages, and seagrass beds for the Caribbean. Most of the stresses affecting marine resources throughout the Caribbean (e.g. damage from boats, hurricanes and coral diseases) are also causing deterioration in these MPAs. Living coral cover has decreased and macroalgal cover has increased. Seagrass densities have decreased because of storms and anchor damage. Intensive fishing in the US Virgin Islands has caused loss of spawning aggregations and decreases in mean fish size and abundance. Groupers and snappers are far less abundant and herbivorous fishes comprise a greater proportion of samples than in the 1960s. Effects of intensive fishing are evident even within MPA boundaries. Although only traditional fishing with traps of 'conventional design' is allowed, commercial trap fishing is occurring. Visual samples of fishes inside and outside Virgin Islands National 'Park showed no significant differences in number of species, biomass, or mean size of fishes. Similarly, the number of fishes per trap was statistically similar inside and outside park waters. These MPAs have not been effective because an unprecedented combination of natural and human factors is assaulting the resources, some of the greatest damage is from stresses outside the control of park managers (e.g. hurricanes), and enforcement of the few regulations has been limited. Fully functioning MPAs which prohibit fishing and other extractive uses (e.g. no

    NOAA's National Geodetic Survey began the Gravity for the Redefinition of the American Vertical Datum (GRAV-D) program in an effort to modernize and unify vertical datums in all states and territories. As a part of this program, NGS collected aerogravity profiles over the islands of Puerto Rico and the U.S. Virgin Islands in January 2009. A Citation II aircraft was equipped with an airborne gravimeter, GPS receiver, and a GPS/Inertial unit. Absolute gravity and GPS ties were made to multiple ground sites to ensure consistency in the results. The main survey covered a region of approximately 400 km by 500 km with flight altitudes of 10,668 m (35,000ft) and with 10 km track spacing. Cross-track profiles at 40 km spacing were also collected to establish an accuracy of 1.34 mGals RMSE. In addition to the high altitude flights, two more flights were made primarily over terrestrial areas at 1,524 m (5,000 ft) to obtain higher resolution information in these regions. There were no cross-ties established for these lower altitude flights. Additionally, terrestrial surveys were also conducted to better tie ground sites and to serve as control for later analysis for available but older terrestrial and marine gravity data in the region already held by NGS. The aerogravity data were analyzed and at least internally compared to obtain the optimal results before being published on the web. In this study, the aerogravity data were compared to available global gravity models derived from satellite missions (GRACE & GOCE) to evaluate their long wavelength character (e.g., potential biases and trends). The vetted satellite-aerogravity data were then combined and used to evaluate surface data (terrestrial and marine) in the region to remove any potential systematic effects. Finally, all these data were combined into a gravimetric geoid height model and evaluated with an eye to eventual use as a GNSS-accessed vertical datum.

    and large-scale agricultural operations are not feasible. The island of Hawaii is the largest island of the State (fig. 33) and has the highest altitude at 13,796 feet. Maui is about 10,000 feet above sea level in its eastern part and about 5,800 feet above sea level in its western part; a broad lowland area separates the two parts. Kahoolawe is the smallest of the eight major islands and is only about 1 ,500 feet above sea level in its eastern, highest part. Lanai is about 3,400 feet above sea level in its highest part, but much of the island is less than 1,000 feet above sea level. Molokai is mountainous in its eastern half, where it rises to about 5,000 feet above sea level, but most of the island is less than 1,000 feet above sea level. Oahu has a mountainous ridge along its eastern side and another mountainous area along the western side, where it rises to about 4,000 feet above sea level; however, most of Oahu is less than 1,000 feet above sea level. Kauai is about 5,200 feet above sea level in its central part, but from the base of the mountains shoreward, large areas of the island are less than 1,000 feet above sea level in the southern, eastern, and northern parts. Niihau is mostly less than 1 ,000 feet above sea level, except for a narrow ridge about 1 ,300 feet above sea level along its northeastern side. The topography of each island has a profound effect on development and climate.Puerto Rico and the Virgin Islands of the United States (fig. 66) are located about 1, 100 miles east-southeast of Miami, Fla.

  13. Mesophotic bioerosion: Variability and structural impact on U.S. Virgin Island deep reefs

    Mesophotic reef corals, found 30-150 m below sea level, build complex structures that provide habitats for diverse ecosystems. Whereas bioerosion is known to impact the development and persistence of shallow reef structures, little is known regarding the extent of mesophotic bioerosion or how it might affect deeper reef geomorphology and carbonate accretion. Originally pristine experimental coral substrates and collected coral rubble were both used to investigate the variation and significance of mesophotic coral reef bioerosion south of St. Thomas, U.S. Virgin Islands. Bioerosion rates were calculated from experimental coral substrates exposed as framework for 1 and 2 years at four structurally distinct mesophotic coral reef habitats (between 30 and 45 m) as well as at a mid-shelf patch reef (21 m) and a shallow fringing patch reef (9 m). The long-term effects of macroboring were assessed by examining coral rubble collected at all sites. Overall, differences in bioerosional processes were found between shallow and mesophotic reefs. Increases in bioerosion on experimental substrates (amount of weight lost) were related to both decreasing seawater depth and increasing biomass of bioeroding parrotfish. Significant differences in coral skeleton bioerosion rates were also found between the transitional mesophotic reef zone (30-35 m) and the upper mesophotic reef zone (35-50 m) after 2 years of exposure, ranging from - 19.6 to 3.7 g/year. Total coral rubble macroboring was greater at most deep sites compared to shallower sites. Bioerosional grazing was found to dominate initial substrate modification in reefs 30.7 m and shallower, but sponges are believed to act as the main time-averaged long-term substrate bioeroders in reefs between 35 and 50 m. Although initial substrate bioerosion rates of a uniform substrate were relatively homogeneous in the 35-50 m depth zone, comparison of site composition suggests that mesophotic bioerosion will vary depending on the amount

    The Puerto Rico Seismic Network at the University of Puerto Rico at Mayagüez is a regional earthquake and tsunami monitoring institute. One of its primary objective is to provide timely and reliable earthquake and tsunami information and warning to the state (Puerto Rico) and local governments, the US and British Virgin Islands, as well as to the general public. In the past five years, it has been expanding its operations for the establishment of a Caribbean Tsunami Warning Center. With funding of the Puerto Rico government and NOAA, it is operated 24 hours per day and 7 days per week. Broadband seismometers are generally unable to capture the full bandwidth of long period ground motions following very large earthquakes. As a result, it is difficult to rapidly estimate the true magnitudes of large earthquakes using only seismic data. High-rate GPS has been justified as a very useful tool in recording long-period and permanent earthquake ground motions. Estimation of the true magnitude (and therefore tsunami potential) of large earthquakes may be determined more accurately in a timely manner (minutes after the quake) using high rate GPS observations. With the major aim of improving the ability of the PRSN in rapidly and precisely monitoring large earthquakes, NSF funded a Major Research Instrumentation (MRI) project, Acquisition of 9 High-rate GPS Units for Developing a Broadband Earthquake Observation System in Puerto Rico and the U.S. Virgin Islands (EAR-0722540, August 1, 2007-July 31, 2009). The major purpose of this project is to build a high-rate GPS network in Puerto Rico and the U.S. Virgin Islands. The GPS network includes 3 campaign and 6 permanent GPS stations. These campaign stations were designed to use in emergency response after large earthquakes to get co-seismic and post-seismic displacement. These six permanent stations were designed to complement current seismic observation system of Puerto Rico and U.S. Virgin Islands. We have installed three

    Hidden in the documents of the dark past of the trans-Atlantic slavery are gems of ethnomedicinal observations, supported by herbarium specimens, which tell of the traditional medicine of a by-gone slave society in the Caribbean. In the context of the former Danish West Indies (now US Virgin Islands), we identify pre-1900 medicinal plants and their historical uses, and trace their status in the traditional medicine of St. Croix today (2014). By a combined historical and ethnobotanical approach we assess the scale of loss and preservation of traditional medicinal knowledge on St. Croix, and explore the drivers involved in the disappearance of knowledge in the oral tradition of medicine. Names, uses and identities of 18th and 19th century medicinal plant uses in the Danish West Indies were derived from manuscripts and publications of Von Rohr (1757/58), Oldendorp (1777), West (1793), Benzon (1822), Riise (1853), Eggers (1876;1879) and Berg and Eggers (1888). The presence of the plant species in the pre-1900 Danish West Indies was confirmed by review of herbarium specimens in the University of Copenhagen Herbarium (C). The same species were collected on St. Croix in 2014 or their ecological status discussed with local specialists. Semi-structured interviews supported by photographs and specimens were conducted with six medicinal plant specialist on St. Croix, to document and compare contemporary names and uses of the historically used medicinal plants. The historic ethnomedicinal sources revealed 102 medicinal uses of 64 plant species. Thirty-eight (37%) of the pre-1900 medicinal uses were traced in interviews, while sixty-four uses (63%) appear to be forgotten, discontinued or otherwise lost. Thirteen species appear to have entirely lost their status as medicinal plants on St. Croix, while 32 species (50%) have lost uses while retaining or gaining others. While 20% of the lost medicinal plant uses can be explained by biodiversity loss, and others likely have become

    Satellite tracking in marine turtle studies can reveal much about their spatial use of breeding areas, migration zones, and foraging sites. We assessed spatial habitat-use patterns of 10 adult female green turtles (Chelonia mydas) nesting at Buck Island Reef National Monument, U.S. Virgin Islands (BIRNM) from 2011 – 2014. Turtles ranged in size from 89.0 – 115.9 cm CCL (mean + SD = 106.8 + 7.7 cm). The inter-nesting period across all turtles ranged from 31 July to 4 November, and sizes of the 50% core-use areas during inter-nesting ranged from 4.2 – 19.0 km2. Inter-nesting core-use areas were located up to1.4 km from shore and had bathymetry values ranging from -17.0 to -13.0 m. Seven of the ten turtles remained locally resident after the nesting season. Five turtles (50%) foraged around Buck Island, two foraged around the island of St. Croix, and the other three (30%) made longer-distance migrations to Antigua, St. Kitts & Nevis, and Venezuela. Further, five turtles had foraging centroids within protected areas. Delineating spatial areas and identifying temporal periods of nearshore habitat-use can be useful for natural resource managers with responsibility for overseeing vulnerable habitats and protected marine turtle populations.

    2012-09-01

    A long-term study of the scleractinian coral Acropora palmata in the US Virgin Islands (USVI) showed that diseases, particularly white pox, are limiting the recovery of this threatened species. Colonies of A. palmata in Haulover Bay, within Virgin Islands National Park, St. John, were examined monthly in situ for signs of disease and other stressors from January 2003 through December 2009. During the study, 89.9 % of the colonies ( n = 69) exhibited disease, including white pox (87 %), white band (13 %), and unknown (9 %). Monthly disease prevalence ranged from 0 to 57 %, and disease was the most significant cause of complete colony mortality ( n = 17). A positive correlation was found between water temperature and disease prevalence, but not incidence. Annual average disease prevalence and incidence remained constant during the study. Colonies generally showed an increase in the estimated amount of total living tissue from growth, but 25 (36.2 %) of the colonies died. Acropora palmata bleached in the USVI for the first time during the 2005 Caribbean bleaching event. Only one of the 23 colonies that bleached appeared to die directly from bleaching. In 2005, corals that bleached had greater disease prevalence than those that did not bleach. Just over half (52 %) of the colonies incurred some physical damage. Monitoring of fragments (broken branches) that were generated by physical damage through June 2007 showed that 46.1 % died and 28.4 % remained alive; the fragments that attached to the substrate survived longer than those that did not. Recent surveys showed an increase in the total number of colonies within the reef area, formed from both asexual and sexual reproduction. Genotype analysis of 48 of the originally monitored corals indicated that 43 grew from sexual recruits supporting the conclusion that both asexual and sexual reproduction are contributing to an increase in colony density at this site.

    Marine geophysical cruises Antithesis (2013-2016) investigate the impact of the variations in interplate geometry onto margin tectonic deformation along the strongly oblique Lesser Antilles subduction zone. A striking features of this margin is the drastic increase in earthquake number from the quiet Barbuda-St Martin segment to the Virgin Islands platform. Wide-angle seismic data highlight a northward shallowing of the downgoing plate: in a 150 km distance from the deformation front, the slab dipping angle in the convergence direction decreases from 12° offshore of Antigua Island to 7° offshore of Virgin Islands. North-South wide-angle seismic line substantiates a drastic slab-dip change that likely causes this northward shallowing. This dip change is located beneath the southern tip of the Virgin Islands platform where the Anegada Passage entails the upper plate. Based on deep seismic lines and bathymetric data, the Anegada Passage is a 450 km long W-E trending set of pull-apart basins and strike-slip faults that extends from the Lesser Antilles accretionary prism to Puerto Rico. The newly observed sedimentary architecture within pull-apart Sombrero and Malliwana basins indicates a polyphased tectonic history. A past prominent NW-SE extensive to transtensive phase, possibly related to the Bahamas Bank collision, opened the Anegada Passage as previously published. Transpressive tectonic evidences indicate that these structures have been recently reactivated in an en-echelon sinistral strike-slip system. The interpreted strain ellipsoid is consistent with deformation partitioning. We propose that the slab northward shallowing increases the interplate coupling and the seismic activity beneath the Virgin Islands platform comparatively to the quiet Barbuda-St Martin segment. It is noteworthy that the major tectonic partitioning structure in the Lesser Antilles forearc is located above the slab dip change where the interplate seismic coupling increases.

    Full Text Available To test the hypotheses that U.S. Virgin Islanders’ knowledge about local coral reefs is correlated with behavior, and that different sociological groups of residents have different patterns of knowledge and behavior, a mixed approach to surveying residents was used: (1 personal interviews were held in public locations and (2 an online version of the survey was administered to residents of the U.S. Virgin Islands. From July-October 2008, 462 residents over 18 years old were surveyed. Results indicate that people who engaged in outdoor activities knew significantly more about coral reefs (Spearman p<0.01, r2=0.128. Those more knowledgeable about coral reefs engaged in more positive stewardship activities (e.g. beach clean-ups (Spearman p<0.01, r2=0.127.

    2012-01-01

    The Virgin Islands and Puerto Rico contain marine reserves and protected areas that encompass a variety of tropical ecosystems, including coral reefs, mangroves, and seagrass beds. Reserves and protected areas are established for a variety of reasons, such as preserving nursery habitats and biodiversity, or reducing anthropogenic effects associated with pollution and land use. Questions remain regarding the effectiveness of these designated areas in preserving and protecting spatially connected habitats and associated fishes and invertebrates. Scientists from the U.S. Geological Survey (USGS), University of Florida, and Arkansas State University are collaborating on interdisciplinary research in the Virgin Islands and Puerto Rico to examine the biodiversity and trophic dynamics of fishes and invertebrates residing in connected mangroves, seagrasses, and coral reefs to discern the effectiveness of current marine reserves and protected areas for conserving reef resources.

    In the northeast Caribbean, doldrum-like conditions combined with elevated water temperatures in the summer/fall 2005 created the most severe coral bleaching event ever documented within this region. Video monitoring of 100 randomly chosen, permanent transects at five study sites in the US Virgin Islands revealed over 90% of the scleractinian coral cover showed signs of thermal stress by paling or becoming completely white. Lower water temperatures in October allowed some re-coloring of corals; however, a subsequent unprecedented regional outbreak of coral disease affected all sites. Five known diseases or syndromes were recorded; however, most lesions showed signs similar to white plague. Nineteen scleractinian species were affected by disease, with >90% of the disease-induced lesions occurring on the genus Montastraea. The disease outbreak peaked several months after the onset of bleaching at all sites but did not occur at the same time. The mean number of disease-induced lesions increased 51-fold and the mean area of disease-associated mortality increased 13-fold when compared with pre-bleaching disease levels. In the 12 months following the onset of bleaching, coral cover declined at all sites (average loss: 51.5%, range: 42.4-61.8%) reducing the five-site average from 21.4% before bleaching to 10.3% with most mortality caused by white plague disease, not bleaching. Continued losses through October 2007 reduced the average coral cover of the five sites to 8.3% (average 2-year loss: 61.1%, range: 53.0-79.3%). Mean cover by M. annularis (complex) decreased 51%, Colpophyllia natans 78% and Agaricia agaricites 87%. Isolated disease outbreaks have been documented before in the Virgin Islands, but never as widespread or devastating as the one that occurred after the 2005 Caribbean coral-bleaching event. This study provides insight into the effects of continued seawater warming and subsequent coral bleaching events in the Caribbean and highlights the need to

  7. Abundance of commercially important reef fish indicates different levels of over-exploitation across shelves of the U.S. Virgin Islands

    Science.gov (United States)

    The United States Virgin Islands are comprised of two separate insular platforms separated by the deep water Anegada Passage. Although managed by the same regulations, as one fishery, several physical and spatial differences exist between the two northern shelf islands, St. Thomas and St. John, and isolated St. Croix. Based on two long-term fisheries independent datasets, collected by the U.S. Virgin Islands Territorial Coral Reef Monitoring Program and the National Oceanographic and Atmospheric Administration Center for Coastal Monitoring and Assessment, there were significant differences between the northern USVI and St. Croix in both the occurrence and size of several species of large and commercially important reef fishes. These fishes are primarily apex piscivores and generally the first species over-exploited in small-scale fisheries. The disparities between the fish communities on the two island shelves cannot be explained solely by differences in habitat (coral cover, rugosity) or fisheries management, such as relative amount of marine protected area in local waters. They are instead probably caused by a combination of several other interrelated factors including water depth, fishing methodology, fishable area, and the presence or absence of viable fish spawning areas. This study considers those aspects, and illustrates the need for management of island artisanal fisheries that is tailored to the physical and spatial constraints imposed by insular platforms.

  8. 7Be as an Indicator of Terrigenous Sediment Input to Coastal Environments: St. John, US Virgin Islands

    In high-relief, tropical island settings, sediment runoff is a threat to the health of down-slope coastal environments, including but not limited to coral reefs. A study on St. John, US Virgin Islands, utilizes 7Be radioisotope activities of sediments to provide insight into terrigenous sediment dynamics on monthly to seasonal time-scales. With a 53-day half-life, 7Be has an atmospheric source, therefore, 7Be can be used as an indicator for sediment input associated with rainfall/runoff. A combination of samples collected from watersheds, coastal sediment traps, and bottom sediments adjacent to traps, were analyzed for 7Be activity to determine variability in sediment input and accumulation. 7Be activities of sediments from watersheds are generally low or not detected, indicating that 7Be input associated with rainfall is not accumulating within the watershed, but is quickly transported to the coast. Exceptions include retention ponds and coastal salt ponds, which inherently trap sediments prior to input into coastal marine environments. Terrigenous sediment input to the coast is reflected by high 7Be activities measured in sediment trap samples. Bottom samples adjacent to traps often do not have detectable 7Be indicating that resuspension is not likely contributing to sediments accumulating in traps, and that terrigenous sediments are not accumulating in these settings. Where 7Be is detected in bottom sediments activities are lower than the adjacent trap and are located where sediment is more likely to accumulate including sheltered areas (e.g. Coral Harbor), deep water, and locations that indicate higher sediment input (i.e. higher trap 7Be activity). An increased understanding of terrigenous sediment dynamics in these coastal environments provides critical information about acute (terrigenous input with subsequent export offshore) vs chronic (terrigenous input with accumulation) influences on coastal ecosystems in both natural and anthropogenic settings.

  10. Monitoring the effect of watershed development and climate on coral reefs in the US Virgin Islands using satellite based sensors

    Science.gov (United States)

    Kerrigan, K.; Ali, K. A.

    2016-02-01

    Previous research in the US Virgin Islands (USVI) has demonstrated that land-based sources of pollution associated with watershed development are one of the primary causes of coral reef degradation. Combined with projections of increased storm frequency from climate change, coral reef communities are facing unprecedented pressures. Water quality is a key index that can be used to assess stress on these environments. Current assessment methods are based on in situ measurements, suggesting the need for more effective monitoring. Satellite remote sensing provides timely and spatially explicit information regarding changes in aquatic systems once the data is calibrated using in situ measurements. The challenges when utilizing high resolution satellite sensors to acquire data in USVI are accounting for atmospheric path radiance, absorption from optically complex particles in the water column (phytoplankton, suspended sediments, and colored dissolved organic matter), and bottom reflectance from various substrates. In this study, field and lab based data were collected from 18 sites within the Caribbean Sea across St. Thomas and St. John to characterize these optical water quality parameters (WQPs) and bottom reflectance of different substrates. Results show that the optical properties of these waters are a function of multiple WQPs with chlorophyll-a values ranging from 0.10 to 2.35 µg/l and total suspended matter (TSM) values between 8.97 and 15.70 mg/l. Currently, a regionally tiered bio-optical model is being developed to accurately quantify WQPs in St. Thomas and St. John using in situ hyperspectral and satellite datasets. Successful generation of this model would strongly advance tools for near-real-time and long-term monitoring at large spatial scales.

    Poorly lithified to unconsolidated carbonate and clastic sedimentary rocks of Tertiary (Oligocene to Pliocene) and Quaternary (Pleistocene to Holocene) age compose the South Coast aquifer and the North Coast limestone aquifer system of Puerto Rico; poorly lithified to unlithified carbonate rocks of late Tertiary (early Miocene to Pliocene) age make up the Kingshill aquifer of St. Croix, U.S. Virgin Islands. The South Coast aquifer, North Coast limestone aquifer system, and Kingshill aquifer are the most areally extensive and function as the major sources of ground water in the U.S. Caribbean Islands Regional Aquifer-System Analysis (CI-RASA) study area. In Puerto Rico's South Coast ground-water province, more than 1,000 meters of clastic and carbonate rocks of Oligocene to Pliocene age infill the South Coast Tertiary Basin. The pattern of lithofacies within this basin appears to have been controlled by changes in base level that were, at times, dominated by tectonic movement (uplift and subsidence), but were also influenced by eustasy. Deposition of the 70-kilometer long and 3- to 8-kilometer wide fan-delta plain that covers much of the South Coast ground-water province occurred largely in response to glacially-induced changes in sea level and climate during the Quaternary period. Tectonic movement played a much less important role during the Quaternary. The North Coast ground-water province of Puerto Rico is underlain by homoclinal coastal plain wedge of carbonate and siliciclastic rocks that infill the North Coast Tertiary Basin and thicken to more than 1,700 meters. A thin basal siliciclastic sequence of late Oligocene age is overlain by a thick section of mostly carbonate rocks of Oligocene to middle Miocene age. Globigerinid limestone of late Miocene to Pliocene age crops out and lies in the shallow subsurface areas of northwestern Puerto Rico. Oligocene to middle Miocene age rocks tentatively can be divided into five depositional sequences and associated

  12. Neotropical dry forests of the Caribbean: Secondary forest dynamics and restoration in St. Croix, US Virgin Islands

    Science.gov (United States)

    Daley, Brian F.

    Neotropical dry forests exist today mainly as secondary forests heavily influenced by exotic plants. This project analyzes land-cover change and secondary dry forest dynamics in three distinct phases (land cover change, secondary forest succession and forest rehabilitation), using St. Croix, US Virgin Islands as an example. Using Landsat satellite images and other data layers, I created classified land cover maps of St. Croix for 1992 and 2002. Forest was the dominant (56%) cover type on both dates, followed by development, grassland/pastures and water. A land cover change analysis comparing the two images revealed that 15% of the study area experienced a change either to (8%) or from (7%) forest. Grassland was the cover most likely to change and decreased from 16% to 11%, converted primarily to development. The overall result is a landscape trending toward younger forests, and increased forest fragmentation and development. In a second study, vegetation data from a chronosequence of secondary forests was analyzed for changes to forest structure, species composition and presence of exotic species. The leguminous exotic tree Leucaena leucocephala was by far the most frequently observed tree and dominated all stands, except those over 50 years old. Species diversity was significantly ( pforests in the two oldest age classes and there was a strong trend toward increasing canopy complexity with increased age. However, age class accounted for only a small portion of variability in species diversity, indicating other influencing factors. Slope, elevation, aspect and soil were not significant and sites with long histories of intensive agricultural land-use remained low in species diversity and dominated by exotics >50 years after abandonment. In a third experiment, a 'gap planting' method for establishing four rare native tree species was tested on a site experiencing arrested succession. All four species successfully established at >69% survival in 3m diameter gaps

  14. delta18O variations in the Halimeda of Virgin Islands sands: evidence of cool water in the northeast Carribean, late Holocene

    Science.gov (United States)

    Holmes, Charles W.

    1983-01-01

    Halimeda segments from carbonate sands on the Virgin Islands platform have delta 18 O versus PDB isotopic values ranging from -0.3% to -1.3% (x = -0.9%). Modern Halimeda segments from the same area have a measured delta18 O ranging from -2.0% to -2.5% PDB (x = -2.15%), and the carbonate skeleton appears to have formed in isotopic equilibrium with the oceanic waters on the platform. Biologic and geochemical data indicate that the sand deposits have accumulated under physical and chemical conditions similar to the modern shelf environment. 14 C data suggest that the sand was deposited over an approximate 5800-year span, centering about 4000 years B.P. The average isotopic difference of 1.25% between the Holocene and modern carbonate indicates that the late Holocene Halimeda lived in waters approximately 4 degrees cooler than the present.

    The study, Energy Vulnerability Assessment of the US Pacific Islands, was mandated by the Congress of the United States as stated in House Resolution 776-220 of 1992, Section 1406. The resolution states that the US Secretary of Energy shall conduct a study of the implications of the unique vulnerabilities of the insular areas to an oil supply disruption. Such study shall outline how the insular areas shall gain access to vital oil supplies during times of national emergency. The resolution defines insular areas as the US Virgin Islands, Puerto Rico, Guam, American Samoa, the Commonwealth of the Northern Mariana Islands, and Palau. The US Virgin Islands and Puerto Rico are not included in this report. The US Department of Energy (USDOE) has broadened the scope of the study contained in the House Resolution to include emergency preparedness and response strategies which would reduce vulnerability to an oil supply disruption as well as steps to ameliorate adverse economic consequences. This includes a review of alternative energy technologies with respect to their potential for reducing dependence on imported petroleum. USDOE has outlined the four tasks of the energy vulnerability assessment as the following: (1) for each island, determine crude oil and refined product demand/supply, and characterize energy and economic infrastructure; (2) forecast global and regional oil trade flow patterns, energy demand/supply, and economic activities; (3) formulate oil supply disruption scenarios and ascertain the general and unique vulnerabilities of these islands to oil supply disruptions; and (4) outline emergency preparedness and response options to secure oil supplies in the short run, and reduce dependence on imported oil in the longer term.

    Queen conch (Strombus gigas) are listed in CITES Appendix II. Populations may be declining due to anthropogenic inputs that include pollutants from boating activity. In the British Virgin Islands (BVI), some conch exhibit imposex, a condition in which male external genitalia are present in female conch. Previous studies suggest that tributyltin (TBT), an antifouling chemical used in boat paint, is correlated to increased incidence of imposex although the mechanisms leading to imposex are not known. The present study utilized a Queen conch microarray to measure the response of the ovarian transcriptome in conch inhabiting polluted environments with high TBT levels in the BVI. The polluted sites, Road Harbour (RH) and Trellis Bay (TB), are areas with high boating activity while the reference sites, Guana Island (GI) and Anegada (AN), are areas with low boating activity. There were 754 and 898 probes differentially expressed in the ovary of conch collected at RH and TB respectively compared to conch collected at GI. Of the genes that were differentially expressed at both sites, > 10% were shared suggesting that these sites have additional environmental factors influencing gene expression patterns. Functional enrichment analysis showed that the biological processes of cell proliferation, translation, and oxidative stress were over-represented in the polluted sites. Gene set enrichment analysis revealed that transcripts involved in the biological processes of general metabolism, immune, lipid metabolism, and stress were affected in conch from polluted environments. Interestingly, altered stress genes appeared to be more prevalent in conch collected from RH than TB, corresponding to the higher TBT load at RH compared to TB. Our study shows that stress pathways are affected in conch ovary in environments that experience heavy boating activity in the BVIs, although we are unable to directly link changes at the transcriptomics level to high TBT levels.

    Spirituality may contribute to the health advantage of foreign-born blacks compared to United States (US)-born blacks. The objective of this study was to test the hypothesis that spirituality attenuates the association of psychosocial stress to stress-associated metabolic risk factors among foreign-born Caribbean blacks living in a US jurisdiction. Data on demographic factors, anthropometric measurements (height, weight and waist), fasting glucose and insulin, lifestyle behaviors (smoking and alcohol use), psychosocial stress and spirituality were collected from a population-based sample of 319 Afro-Caribbean immigrants, ages 20 and older, who were recruited between 1995 and 2000 in the Virgin Islands of the United States (USVI). Glucose and insulin measurements were used to estimate insulin resistance by the homeostasis model assessment (HOMA-IR) method. Participants were classified into three levels of spirituality, "low", "medium" and "high" based on the distribution of spirituality scores. Stepwise regression analyses were used to identify the significant predictors of waist circumference and HOMA-IR within each level of spirituality. The predictors of waist circumference and HOMA-IR varied across the levels of spirituality. Psychosocial stress was an independent predictor of waist and HOMA-IR only among participants with a low level of spirituality. Spirituality appears to attenuate the association of psychosocial stress to waist circumference and insulin resistance among Afro-Caribbean immigrants in the USVI.

    As of May 2, 2017, the U.S. Virgin Islands (USVI), comprising St. Thomas, St. John, and St. Croix, had reported 1,021 probable or confirmed cases* of Zika virus disease in its population of approximately 100,000 (1); 222 symptomatic and asymptomatic pregnant women in the USVI had tested positive for Zika virus. In January 2016, USVI Department of Health (USVI DOH) initiated Zika response measures, including surveillance, vector control, and a communications program. Interventions included education and outreach, distribution of Zika prevention kits † to pregnant women in the USVI, and provision of free Zika virus laboratory testing and vector control services. In November 2016, USVI DOH staff members conducted interviews with convenience samples of community members and pregnant women to gather feedback about current and proposed interventions (2). Pregnant women reported taking a median of two actions to protect themselves from Zika, with repellent use being the most commonly reported action. Community members reported taking a median of one action and were supportive of several proposed vector control approaches. Whereas multiple pregnant women and community members reported hearing messages about the cause and consequences of Zika virus infections, few recalled messages about specific actions they could take to protect themselves. Integrating evaluation into response measures permits ongoing assessment of intervention effectiveness and supports improvement to serve the population's needs.

    Full Text Available The wooden carving of Our Lady of Candelaria, discovered in the municipality of the same name on the island of Tenerife (Canary Islands during the first half of the fifteenth century, had nearly two hundred letters of the Latin alphabet inscribed on her garments. Unfortunately the original carving disappeared after the storm that took place in 1826. Once the original letters on the first image were discovered by means of analysing both textual and artistic documentation and sources, we conclude that the text is archaic-Berber language used by the islanders, Insular-Amazigh, which no longer exists in the present day. Having discussed lexical, morphological, syntactic and phonetic aspects of this archaic language, as well as conducted a semantic analysis of the carving both from the native aboriginal perspective and the Christian one, we expound here our proposal of the meaning of the letters engraved on the Marian carving of Candelaria from its lexical voices and roots of their Berber and Insular-Amazigh languages, with the previous proposed solutions.

    Three kinds of extreme waves are evidenced geologically on Anegada, a low-lying island 120 km south of the Puerto Rico Trench: (1) Modern and historical storms: A coral-rubble ridge lining the island's north shore was refreshed by modern storms and was probably emplaced by historical hurricanes. A category 4 storm in 2010 aggraded sandy fans within 50 m of the south shore and stirred up microbial debris in interior salt ponds. (2) Unusual flooding between 1650 and 1800 CE which may resemble the 1755 Lisbon tsunami: A sand-and-shell sheet extends as much as 1.5 km inland. Its shells were derived from an interior marine pond, not from the reef flat. (3) Catastrophic overwash before 1500 CE: Coral clasts, limestone boulders, and carbonate sand were deposited hundreds of meters inland from the north shore. Many of the coral clasts are complete colonies of the brain coral Diploria strigosa on the order of at least 1 m in diameter. The limestone clasts were derived from cemented Pleistocene deposits. Some form elongate fields pendant to likely sources to their north, and others are imbricated slabs that dip to the north. The carbonate sand locally contains articulated valves of the lucine Codakia orbicularis and the conch Lobatus gigas, which today inhabit the sandy shallows between the island's north shore and the fringing reef. All the dated coral clasts, lucines, and conches are older than 1500 CE, and most are in the range 1200-1480 CE. The extreme waves of type (3) were previously ascribed to a tsunami from faulting along the Puerto Rico Trench. We are also evaluating an alternative explanation - a tsunami-like bore from infragravity waves similar to those produced in the Philippines by 2013 Typhoon Haiyan.

    Land development on the island of St. John, US Virgin Islands is increasing terrigenous sediment loads into coastal bays and this is adversely affecting its sensitive, near-shore coral reef systems. Accelerated erosion of by-products originating from igneous bedrock may contribute metal-rich sediment to ephemeral streams and bays around St. John. In order to determine how development is affecting the production and transportation of land-based metals from watersheds to reef environments, we compare the chemistry and mineralogy of bedrock and sediment of both an undeveloped and a developed watershed and their corresponding bays. Both watersheds are comprised of bedrock of similar lithology (Water Island Formation: plagiorhyolite and basalt). Our study objectives are to: 1) determine what metal elements could serve as reliable stable geochemical tracers to track the transport of land-derived sediments to reefs; 2) document the total change in metal concentrations from in-situ bedrock and sediment along travel paths as the sediment gets transported from the watersheds to the reefs; and 3) estimate erosion rates from active sediment sources and metal accumulation rates within the marine environment. Whole rock, soil, stream, shore and reef sediment samples were collected from both study areas to represent a ridge to reef progression of material as it is eroded from the bedrock and transported to the reefs. Samples of in-situ rock and sediments were collected by hand, while material representing sediment being eroded from the watersheds and settling in the ephemeral streams and bays was captured by terrestrial and marine sediment traps. Major and trace element concentrations and the mineralogy of rock and sediments were analyzed using X-ray fluorescence, petrography and X-ray diffraction. Analyses of bedrock samples reveal mineral and elemental compositions typical of basalt and plagiorhyolite. In hydrothermally altered bedrock Ba and K concentrations elevated above non

    Human activities such as deforestation, agriculture, and the building of dirt roads may increase soil erosion and the delivery of land-based sediment into coastal waters from steep sub-tropical islands. These changes may also affect water-rock interaction, which alters the geochemistry of storm waters and the clay mineralogy of eroded sediments. In the US Virgin Islands, land-based sedimentation is thought to be a major cause of the decline of near-shore coral reefs. The objective of this study was to 1) evaluate whether chemical erosion (water-rock interaction) during storms affected the major-element chemistry of storm-water and the clay mineralogy of eroded sediments; and 2) determine if enhanced erosion associated with human activities may impact these parameters. Our approach was to compare storm-water and sediment geochemistry and modeled erosion rates between developed (Coral Bay) and undeveloped (Lameshur) watersheds on St. John, USVI. Terrestrial and marine sediment samples and runoff samples from three storm events, including Hurricane Otto (Oct. 7-9th), were collected during the 2010 hurricane season in Coral Bay and Lameshur watersheds and bays. Major elements in storm waters were measured using ICP-AES. The mineral saturation index was calculated using "The Geochemist's Workbench" (GWB), supported by X-Ray Diffraction analysis on clay minerals. The Revised and Modified Universal Soil Loss Equations were used to estimate both annual mean (2010, RUSLE) and storm-event (Hurricane Otto, MUSLE) based erosion rates. In addition, rates of marine terrigenous sediment accumulation were estimated by Loss On Ignition (LOI) analysis of marine sediment collected using submarine sediment trap arrays. Spatial variations in calcium, magnesium, sodium and potassium concentrations in storm water samples were measured and only calcium was statistical different (p<0.05) between the developed and undeveloped study sites during Hurricane Otto.

    Electronic cigarettes (e-cigarettes) are the most frequently used tobacco product among U.S. youths, and past 30-day e-cigarette use is more prevalent among high school students than among adults (1,2). E-cigarettes typically deliver nicotine, and the U.S. Surgeon General has concluded that nicotine exposure during adolescence can cause addiction and can harm the developing adolescent brain (2). Through authority granted by the Family Smoking Prevention and Tobacco Control Act, the Food and Drug Administration (FDA) prohibits e-cigarette sales to minors, free samples, and vending machine sales, except in adult-only facilities (3). States, localities, territories, and tribes maintain broad authority to adopt additional or more stringent requirements regarding tobacco product use, sales, marketing, and other topics (2,4). To understand the current e-cigarette policy landscape in the United States, CDC assessed state and territorial laws that 1) prohibit e-cigarette use and conventional tobacco smoking indoors in restaurants, bars, and worksites; 2) require a retail license to sell e-cigarettes; 3) prohibit e-cigarette self-service displays (e.g., requirement that products be kept behind the counter or in a locked box); 4) establish 21 years as the minimum age of purchase for all tobacco products, including e-cigarettes (tobacco-21); and 5) apply an excise tax to e-cigarettes. As of September 30, 2017, eight states, the District of Columbia (DC), and Puerto Rico prohibited indoor e-cigarette use and smoking in indoor areas of restaurants, bars, and worksites; 16 states, DC, and the U.S. Virgin Islands required a retail license to sell e-cigarettes; 26 states prohibited e-cigarette self-service displays; five states, DC, and Guam had tobacco-21 laws; and eight states, DC, Puerto Rico, and the U.S. Virgin Islands taxed e-cigarettes. Sixteen states had none of the assessed laws. A comprehensive approach that combines state-level strategies to reduce youths' initiation of

    An integrated technical-economic model is used to address water management issues in the French island of Noirmoutier. The model simulates potable water production and supply, potable and non potable water demand and consumption, wastewater collection, treatment and disposal, water storage, transportation and reuse. A variety of water management scenarios is assessed through technical, economic and environmental evaluation. The scenarios include wastewater reclamation and reuse for agricultural and landscape irrigation as well as domestic non potable application, desalination of seawater and brackish groundwater for potable water supply. The study shows that, in Noirmoutier, wastewater reclamation and reuse for crop irrigation is the most cost-effective solution to the lack of water resources and the protection of sensitive environment. Some water management projects which are regarded as having less economic benefit in the short-term may become competitive in the future, as a result of tightened environmental policy, changed public attitudes and advanced water treatment technologies. The model provides an appropriate tool for water resources planning and management.

    Strontium-to-calcium ratios (Sr/Ca) were measured on the skeletal matrix of a core sample from a colony of the massive coral Siderastrea siderea collected in Coral Bay, St. John, U.S. Virgin Islands. Strontium and calcium are incorporated into the coral skeleton during the precipitation of aragonite by the coral polyps and their ratio is highly temperature dependent. The robustness of this temperature dependence makes Sr/Ca a reliable proxy for sea surface temperature (SST). Details presented from the St. John S. siderea core indicate that terrestrial inputs of sediment and freshwater can disrupt the chemical balance and subsequently complicate the utility of Sr/Ca in reconstructing historical SST. An approximately 44-year-long record of Sr/Ca shows that an annual SST signal is recorded but with an increasing Sr/Ca trend from 1980 to present, which is likely the result of runoff from the mountainous terrain of St. John. The overwhelming influence of the terrestrial fingerprint on local seawater chemistry makes utilizing Sr/Ca as a SST proxy in nearshore environments very difficult.

    This technical report presents the results of a study conducted at two alternative brine diffuser sites (A and B) proposed for the Weeks Island salt dome, together with an analysis of the potential physical, chemical, and biological effects of brine disposal for this area of the Gulf of Mexico. Brine would result from either the leaching of salt domes to form or enlarge oil storage caverns, or the subsequent use of these caverns for crude oil storage in the Strategic Petroleum Reserve (SPR) program. Brine leached from the Weeks Island salt dome would be transported through a pipeline which would extend from the salt dome either 27 nautical miles (32 statute miles) for Site A, or 41 nautical miles (47 statute miles) for Site B, into Gulf waters. The brine would be discharged at these sites through an offshore diffuser at a sustained peak rate of 39 ft/sup 3//sec. The disposal of large quantities of brine in the Gulf could have a significant impact on the biology and water quality of the area. Physical and chemical measurements of the marine environment at Sites A and B were taken between September 1977 and July 1978 to correlate the existing environmental conditions with the estimated physical extent of tthe brine discharge as predicted by the MIT model (US Dept. of Commerce, 1977a). Measurements of wind, tide, waves, currents, and stratification (water column structure) were also obtained since the diffusion and dispersion of the brine plume are a function of the local circulation regime. These data were used to calculate both near- and far-field concentrations of brine, and may also be used in the design criteria for diffuser port configuration and verification of the plume model. Biological samples were taken to characterize the sites and to predict potential areas of impact with regard to the discharge. This sampling focused on benthic organisms and demersal fish. (DMC)

In Denmark, extensive quality management initiatives have been implemented throughout hospitals, this was not the case in the Faroese Islands in 2013. The purpose of this study is to investigate the patient safety culture in the National Hospital of the Faroe Islands prior to implementation of quality management initiatives. Methods: The Danish version of the Safety Attitudes Questionnaire (SAQ-DK was distributed electronically to 557 staff members from five medical centers of the hospital, and one administrative unit. SAQ-DK has six cultural dimensions. The proportion of respondents with positive attitudes and mean scale scores were described, and comparison between medical specialties, and between clinical leaders and frontline staff was made using analysis of variance and chi-square test, respectively. Results: The response rate was 65.8% (N=367. Job satisfaction was rated most favorable, and the perceived culture of the top management least favorable. Safety climate was the dimension with the greatest variability across the 28 units. The diagnostic center had the most favorable culture of all centers. More leaders than frontline staff had positive attitudes toward teamwork and safety climate, and working conditions, respectively. Also, the leaders perceived these dimensions more positive than the frontline staff, P<0.05. Among three management levels

    Habitat fragmentation reduces the extent and connectivity of suitable habitats, and can lead to changes in population genetic structure. Limited gene flow among isolated demes can result in increased genetic divergence among populations, and decreased genetic diversity within demes. We assessed patterns of genetic variation in the Caribbean boa Chilabothrus monensis (Epicrates monensis) using two mitochondrial and seven nuclear markers, and relying on the largest number of specimens of these snakes examined to date. Two disjunct subspecies of C. monensis are recognized: the threatened C. m. monensis, endemic to Mona Island, and the rare and endangered C. m. granti, which occurs on various islands of the Puerto Rican Bank. Mitochondrial and nuclear markers revealed unambiguous genetic differences between the taxa, and coalescent species delimitation methods indicated that these snakes likely are different evolutionary lineages, which we recognize at the species level, C. monensis and C. granti. All examined loci in C. monensis (sensu stricto) are monomorphic, which may indicate a recent bottleneck event. Each population of C. granti exclusively contains private mtDNA haplotypes, but five of the seven nuclear genes assayed are monomorphic, and nucleotide diversity is low in the two remaining markers. The faster pace of evolution of mtDNA possibly reflects the present-day isolation of populations of C. granti, whereas the slower substitution rate of nuDNA may instead mirror the relatively recent episodes of connectivity among the populations facilitated by the lower sea level during the Pleistocene. The small degree of overall genetic variation in C. granti suggests that demes of this snake could be managed as a single unit, a practice that would significantly increase their effective population size.

C'est ainsi que la section-type de la formation Kingshill, qui avait été récemment attribuée au Miocène supérieur, est désormais datée du Miocène moyen d'après son riche contenu faunistique en foraminifères planctoniques et nannofossiles calcaires. Les diverses mesures pétrophysiques effectuées dans des niveaux d'environnement de dépôts différents (plate-forme, pente, bassin tendent à prouver que de bonnes porosités et perméabilités, donc de bons réservoirs, pourraient être trouvées dans des séries de pentes ou de fond de bassins associés à des plates-formes carbonatées. Systematic sampling of the main outcrops of Neogene carbonate series on Saint Croix, Virgin Islands, has enabled their stratigraphic extension to be determined. In this way, the Kingshill formation type section, which has recently been attributed to the late Miocene, is henceforth dated from the middle Miocene according to planktonic foraminifers and calcareous nannofossils. The different petrophysical measurements made in strata originated from different depositional environments (shelf, slope, basin tend to prove that good porosities and permeabilities, hence good reservoirs, might be found in slope or basin-bottom series associated with carbonate banks.

    Coral boulders deposited on Anegada, an island 120 km south of the Puerto Rico Trench, record overwash dated to AD 1200-1450 and relative sea-level changes that preceded it. Composed largely of Pleistocene limestone, Anegada is less than 8 m above sea level and is fringed on the north and east by a coral reef where Atlantic Ocean waves break. The lowest parts of the island were washed over from the north in AD 1650-1800, as judged from landforms and deposits reported previously (doi:10.1007/s11069-010-9622-6). The coral boulders indicate overwash of higher elevation and earlier age. The boulders were apparently torn from the adjacent reef by a tsunami of nearby origin, as inferred in companion abstracts on geology and modeling. We found the corals scattered in five areas inland from the north shore. Two of the areas show solitary coral heads 1500 m from the reef. The boulders are more numerous in the three other areas, where they are up to 500-700 m from the reef and up to 4 m above sea level. Some were transported over beach ridges or through breaches cut into them. Others are hundreds of meters inland from a modern storm berm. Most rest on the Pleistocene limestone. Many are overturned. Most are broken but few are whole. The largest measured diameter is 2 m and the greatest measured height is 1 m. Most of the boulders are of the brain coral Diploria strigosa, but smaller Porites asteroides and Montastrea annularis are also present. Some of the D. strigosa retain the rounded shape typical of living heads and are dimpled with holes perhaps left by feather-duster worms. The preservation of these features suggests that many of the boulders came ashore alive. We avoided dating a head that shows field evidence for death before transport; an erosional surface cuts across its youngest growth bands and is covered with the remains of encrusting marine organisms. Among the 18 coral boulders dated, 13 form a young group with ages in the range 890±25 to 1020±25 14C yr BP

  20. Composite Flood Risk for Virgin Island

    Science.gov (United States)

    The Composite Flood Risk layer combines flood hazard datasets from Federal Emergency Management Agency (FEMA) flood zones, NOAA's Shallow Coastal Flooding, and the National Hurricane Center SLOSH model for Storm Surge inundation for category 1, 2, and 3 hurricanes.Geographic areas are represented by a grid of 10 by 10 meter cells and each cell has a ranking based on variation in exposure to flooding hazards: Moderate, High and Extreme exposure. Geographic areas in each input layers are ranked based on their probability of flood risk exposure. The logic was such that areas exposed to flooding on a more frequent basis were given a higher ranking. Thus the ranking incorporates the probability of the area being flooded. For example, even though a Category 3 storm surge has higher flooding elevations, the likelihood of the occurrence is lower than a Category 1 storm surge and therefore the Category 3 flood area is given a lower exposure ranking. Extreme exposure areas are those areas that are exposed to relatively frequent flooding.The ranked input layers are then converted to a raster for the creation of the composite risk layer by using cell statistics in spatial analysis. The highest exposure ranking for a given cell in any of the three input layers is assigned to the corresponding cell in the composite layer.For example, if an area (a cell) is rank as medium in the FEMA layer, moderate in the SLOSH layer, but extreme in the SCF layer, the cell will be considere

  8. Virgin mother or bastard child?

    Directory of Open Access Journals (Sweden)

    John D. Crossan

    2003-11-01

    Full Text Available Virginal conception presumes divine intervention, but divine inter-vention does not necessarily presume virginal conception. In the case of Mary, two phenomena, both unusual in Jewish tradition, are found, namely divine and virginal conception. This article argues that the virginity claim by Christian Jews preceded and generated the adultery accusation by non-Christian Jews. It does so by stating three points. Firstly, that the earliest dated text containing the accusation of Jesus’ bastardy is dependent on the redactional text of Matthew. Secondly, that the general structure of Matthew 1-2 and especially its dyad of Divorce and Remarriage is dependent on the popular traditions about Moses’ conception and birth. Thirdly, that the pre-Matthean tradition of divine and virginal conception is rather a reaction against Roman tradition than coming from Jewish tradition. However, this argument does not take Jesus out of Jewish tradition but, places the Judaism of Jesus’ time firmly within the Roman Empire. It is a Judaism which opposed Rome’s ideological ascendancy and theological eschatology. This article will also be published in A Feminist Companion to (Mariology or (the Jesus Movement, edited by Amy-Jill Levine, Sheffield: Sheffield Academic Press.

    The study involves the terrestrial biological research on the volcanic island, Surtsey, off the coast of Iceland and the neighbouring islands and environs of the Westman Islands, which are situated on the Mid-Atlantic Ridge. An eruption of the volcano in 1973 is studied. The topographical changes on Surtsey were studied in August 1976. It is evident that the southwestern side is constantly being eroded and that the island decreases in area of some 7.5 hectares per year. Results are reported from studies of microorganisms, algae, lichens, moss, vascular plants, insects, birds, and soil, and the nitrogen cycle. Emphasis was placed on revegetation and recolonization of plants, insects, and sea birds.

    There has been increasing effort in recent years to incorporate user needs in technology design and re-design. This project employed a bottom-up approach that engaged end users from the outset. Bottom-up approaches have the potential to bolster novel interventions and move them towards adaptive and evidence-based strategies. The present study concerns an innovative use of solar-powered mosquito trapping systems (SMoTS) to control malaria in western Kenya. Our paper highlights the co-dependence of research associated with the development of the SMoTS technology on one hand and research for enhancing the sustainable uptake of that very same intervention within the community on the other. During the pre-intervention year, we examined the design, re-design and piloting of a novel technology to generate lessons for malaria elimination on Rusinga Island. Initial ideas about many technological necessities were evaluated and re-designed following feedback from various sources, including technical and social research as well as broader interactions with the social environment. We documented the interlocking of the multiple processes and activities that took place through process observation and document reviews. We analysed the data within the conceptual framework of system innovation by identifying mutual shaping between technical and social factors. Our findings illustrate how various project stakeholders including project staff, collaborators, donor, and community members simultaneously pursued interdependent technological transformations and social interests. In the ongoing process, we observed how partial outcomes in the technological domain influenced social events at a later phase and vice versa. Looking at malaria intervention projects employing novel technologies as niches that may evolve towards system innovation, helps to reveal interrelations between the various technical and social aspects. Revealing these interrelations requires a different role for research

    Apart from religious values, virginity is important in different communities because of its prominent role in reducing sexually transmitted diseases and teen pregnancies. Even though virginity testing has been proclaimed an example of violence against women by the World Health Organization, it is still conducted in many countries, including Iran. 16 in-depth, semi-structured interviews were conducted with participants aged 32 to 60 years to elucidate the perceptions and experiences of Iranian examiners of virginity testing. The perception and experience of examiners were reflected in five main themes. The result of this study indicated that virginity testing is more than a medical examination, considering the cultural factors involved and its overt and covert consequences. In Iran, testing is performed for both formal and informal reasons, and examiners view such testing with ambiguity about the accuracy and certainty of the diagnosis and uncertainty about ethics and reproductive rights. Examiners are affected by the overt and covert consequences of virginity testing, beliefs and cultural values underlying virginity testing, and informal and formal reasons for virginity testing.

    Full Text Available Energy is one of the most important factors in the socioeconomic development of a country. In a developing country like Malaysia, the development of islands is mostly related to the availability of electric power. Power generated by renewable energy sources has recently become one of the most promising solutions for the electrification of islands and remote rural areas. But high dependency on weather conditions and the unpredictable nature of these renewable energy sources are the main drawbacks. To overcome this weakness, different green energy sources and power electronic converters need to be integrated with each other. This study presents a battery storage hybrid standalone photovoltaic-wind energy power supply system. In the proposed standalone hybrid system, a DC-DC buck-boost bidirectional converter controller is used to accumulates the surplus hybrid power in the battery bank and supplies this power to the load during the hybrid power shortage by maintaining the constant dc-link voltage. A three-phase voltage source inverter complex vector control scheme is used to control the load side voltage in terms of the voltage amplitude and frequency. Based on the simulation results obtained from MATLAB/Simulink, it has been found that the overall hybrid framework is capable of working under variable weather and load conditions.

    The Big Island site is located in the McKenzie River flood plain, containing remnant habitats of what was once more common in this area. A diverse array of flora and fauna, representing significant wildlife habitats, is present on the site. Stands of undisturbed forested wetlands, along with riparian shrub habitats and numerous streams and ponds, support a diversity of wildlife species, including neotropical migratory songbirds, raptors, mammals, reptiles, and amphibians (including two State-listed Sensitive Critical species). The project is located in eastern Springfield, Oregon (Figure 1). The project area encompasses 187 acres under several ownerships in Section 27 of Township 17S, Range 2W. Despite some invasion of non-native species, the site contains large areas of relatively undisturbed wildlife habitat. Over several site visits, a variety of wildlife and signs of wildlife were observed, including an active great blue heron rookery, red-Legged frog egg masses, signs of beaver, and a bald eagle, Wildlife habitat values resulting from the purchase of this site will contribute toward the goal of mitigating for habitat lost as outlined in the Bonneville Power Administration's (BPA) Mitigation and Enhancement Plan for the Willamette River Basin. Under this Plan, mitigation goals and objectives were developed as a result of the loss of wildlife habitat due to the construction of Federal hydroelectric facilities in the Willamette River Basin. Results of the Habitat Evaluation Procedures (HEP) will be used to: (1) determine the current habitat status of the study area and habitat enhancement potential of the site consistent with wildlife mitigation goals and objectives; and (2) develop a management plan for the area.

  2. Geology of St. John, U.S. Virgin Islands

    Rankin, Douglas W.

    2002-01-01

    The rocks of St. John, which is located near the eastern end of the Greater Antilles and near the northeastern corner of the Caribbean plate, consist of Cretaceous basalt, andesite, keratophyre, their volcaniclastic and hypabyssal intrusive equivalents, and minor calcareous rocks and chert. These rocks were intruded by Tertiary mafic dikes and tonalitic plutons. The oldest rocks formed in an extensional oceanic environment characterized by abundant keratophyre and sheeted dikes. Subduction-related volcanism of the east-west-trending marine Greater Antilles volcanic arc began on St. John near the transition between the Early and Late Cretaceous. South-directed compression, probably caused by the initial collision between the Greater Antilles arc of the Caribbean plate and the Bahama platform of the North American plate, deformed the Cretaceous strata into east-west-trending folds with axial-plane cleavage. Late Eocene tonalitic intrusions, part of the Greater Antilles arc magmatism, produced a contact aureole that is as much as two kilometers wide and that partly annealed the axial-plane cleavage. East-west compression, possibly related to the relative eastward transport of the Caribbean plate in response to the beginning of spreading at the Cayman Trough, produced long-wavelength, low-amplitude folds whose axes plunge gently north and warp the earlier folds. A broad north-plunging syncline-anticline pair occupies most of St. John. The last tectonic event affecting St. John is recorded by a series of post-late Eocene sinistral strike-slip faults related to the early stages of spreading at the Cayman Trough spreading center and sinistral strike-slip accommodation near the northern border of the Caribbean plate. Central St. John is occupied by a rhomb horst bounded by two of these sinistral faults. Unlike other parts of the Greater Antilles, evidence for recent tectonic movement has not been observed on St. John.

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

    KAUST Repository

    Rachman, Rinaldi

    2014-07-23

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

    In this paper the extraction methods of virgin almond oil and its chemical composition are reviewed. The most common methods for obtaining oil are solvent extraction, extraction with supercritical fluids (CO2) and pressure systems (hydraulic and screw presses). The best industrial performance, but also the worst oil quality is achieved by using solvents. Oils obtained by this method cannot be considered virgin oils as they are obtained by chemical treatments. Supercritical fluid extraction results in higher quality oils but at a very high price. Extraction by pressing becomes the best option to achieve high quality oils at an affordable price. With regards chemical composition, almond oil is characterized by its low content in saturated fatty acids and the predominance of monounsaturated, especially oleic acid. Furthermore, almond oil contains antioxidants and fat-soluble bioactive compounds that make it an oil with interesting nutritional and cosmetic properties.

    Thirty years ago when Sir Richard Branson called up Boeing and asked if they had a spare 747, few would have predicted the brash entrepreneur would so radically transform the placid business of air travel. But today, Branson flies airlines on six continents, employs hundreds of jets and, in 2014, was predicting that his spaceship company – Virgin Galactic – would soon open the space frontier to commercial astronauts, payload specialists, scientists and space tourists. With more than 600 seats sold at $250,000 each, what started off as a dream to send people just for the excitement to look back and marvel at Earth, was on the cusp of finally being turned into a business. Then, on October 21, 2014, tragedy struck. SpaceShipTwo was on its most ambitious test flight to date. Seconds after firing its engine, Virgin Galactic’s spaceship was breaking through the sound barrier. In just the three seconds that it took for the vehicle to climb from Mach 0.94 to Mach 1.02, co-pilot Mike Alsbury made what many close...

  18. Virgin olive oil yeasts: A review.

    Science.gov (United States)

    Ciafardini, Gino; Zullo, Biagi Angelo

    2018-04-01

    This review summarizes current knowledge on virgin olive oil yeasts. Newly produced olive oil contains solid particles and micro drops of vegetation water in which yeasts reproduce to become the typical microbiota of olive oil. To date, about seventeen yeast species have been isolated from different types of olive oils and their by-products, of which six species have been identified as new species. Certain yeast species contribute greatly to improving the sensorial characteristics of the newly produced olive oil, whereas other species are considered harmful as they can damage the oil quality through the production of unpleasant flavors and triacylglycerol hydrolysis. Studies carried out in certain yeast strains have demonstrated the presence of defects in olive oil treated with Candida adriatica, Nakazawaea wickerhamii and Candida diddensiae specific strains, while other olive oil samples treated with other Candida diddensiae strains were defect-free after four months of storage and categorized as extra virgin. A new acetic acid producing yeast species, namely, Brettanomyces acidodurans sp. nov., which was recently isolated from olive oil, could be implicated in the wine-vinegary defect of the product. Other aspects related to the activity of the lipase-producing yeasts and the survival of the yeast species in the flavored olive oils are also discussed. Copyright © 2017 Elsevier Ltd.

    Sandro Donnini Mancini

    1999-01-01

    Full Text Available Bottle grade virgin PET (polyethylene terephthalate resin was investigated through five consecutive injection molding steps to simulate recycling cycles. Tests were carried out after each recycling to evaluate degradation, crystallinity (by density and Differential Scanning Calorimetry-DSC measurements, hardness, and tensile and flexural properties. Consecutive recycling resulted in cumulative chain breaks caused by the material's contact with degrading agents such as temperature, oxygen, mechanical stresses, light, and water. In the fifth recycling step, for example, the number of carboxylic end groups, an indicator of the extent of chain-break, tripled in comparison to the initial molecule. The smaller chains that were formed fit more easily among the larger ones, thus increasing the percentage of crystalline phase in the structure. These two changes in the polymer's structure explained the recycled products' final properties, i.e., the injected samples became progressively harder and more fragile in each recycling step.

    2013-01-01

    The influence of olive oil concentration and sensory profile on the odor of virgin olive oil-based cosmetic creams was studied. Four olive oils were selected on the basis of different intensities of positive and defective odor attributes: two extra virgin olive oils, one virgin olive oil, and one ordinary virgin olive oil. Thirty cosmetic creams were prepared, by both cold and hot processing methods, using each of the above oils at concentrations of 3%, 5%, and 10%, in addition to mineral oil controls. A trained sensory panel evaluated the fruitiness and defectiveness intensities in the odor of creams, using unstructured 10-cm scales ranging from "none at all" to "much." The fruity and defective attributes perceived in the odor of creams were significantly influenced by the sensory profile of the starting olive oil, oil concentration, and preparation method. Overall, these findings suggest that virgin olive oils of only slightly fruity odor may be conveniently used for the preparation of cold-processed cosmetic creams, whereas ordinary virgin olive oils appear to be suitable for the preparation of cosmetic creams only by hot processing of the emulsion at a low oil concentration.

    Abboud, Sarah; Jemmott, Loretta Sweet; Sommers, Marilyn S

    2015-12-01

    Virginity is part of our existence in the world as embodied sexual subjects. While many meanings are associated with virginity, in most of the Arab world virginity relates to the presence of a hymen and extends to encompass the honor of the Arab community, and virginity loss commonly relate to first vaginal intercourse. This study explored the meanings of virginity from the perspectives of Arab and Arab American women. A qualitative phenomenological approach, informed by the philosophy of Maurice Merleau-Ponty, was used to conduct in-depth interviews with ten women. We identified one over-arching theme Virginity as Identity , and two major themes Embodiment of Virginity and "We are Arabs." To reach an embodied virginity, participants went through a disembodied virginity process, reflecting society's perceptions and values of virginity related to anatomical presence of a hymen and society's honor. "We are Arabs" describes the ways women identified with the Arab ethnic identity as a shared overall identification, but differed from one lived experience to another, and influenced how participants embodied virginity. Our participants provided a better understanding of the diverse meanings of virginity that move beyond the binary of virginity and virginity loss, and into a spectrum of embodied meanings. Findings suggest the need for future research around sexuality in Arab Americans with attention to socio-political contexts in order to understand the nature and context of sexual initiation and its impact on sexual behaviors and well-being.

  4. Matter transfer during virgin olive oil elaboration

    Gómez Herrera, Carlos

    2007-06-01

    Full Text Available In the course of the process of elaboration of virgin olive oil (whose main stages are crushing, malaxation and centrifugation the transfer of several minor components to the triacylglycerol constituent of the oily globules originally present in the cells of the fruit mesocarp is produced. Such minor components are chemical species present in the olive fruits, as well as those resulting from chemical or enzymatic processes which take place in the olive paste upon crushing. In this paper several types of transferable minor components, as well as those parameters affecting the rates of transfer are studied.Geometric and physical variations of interfacial regions between the oil and other systems in contact with it are discussed. These systems are olive vegetation water, olive pulp components, and fragments of the woody endocarp, as well as the atmospheric air and the tools and equipment of the oil mill.This article concludes with some considerations about the improvements of virgin olive oils achieved by controlling the transfer of minor components.Durante la elaboración del aceite de oliva virgen (cuyas principales etapas son molturación, batido y centrifugación se producen transferencias de diversos componentes menores a los triacilgliceroles originalmente presentes en los glóbulos oleosos de las células del mesocarpio de los frutos.

    Full Text Available Istria and Island Krk are located in the Northern Adriatic region, Republic of Croatia. The majority of oils produced on the islands of this Region correspond to extra virgin classification as a consequence of olive cultivars (Debela, Naska, Rosulja, Slatka, Buza, Carbonera, Bianchera, Leccino. The characterisation of these oils is little known. The objective of this work was the characterisation of virgin olive oils during the 1997/98, 1998/99 and six months of 1999/2000 harvest. Acidity, peroxide value and UV absorption constants were determined for all samples. Fatty acid composition, sterol and aliphatic alcohol contents, saturated fatty acids in the 2-position of the triglyceride and trilinolein content were determined for the virgin olive oils during 1997/98 harvest. The chemical analyses were supported by the determination of polyphenol content expressed as caffeic acid, squalene and α-tocopherol content.Istria y la isla Krk están localizadas en el norte de la región Adriática, República de Croacia.

    The antioxidant properties of virgin coconut oil produced through chilling and fermentation were investigated and compared with refined, bleached and deodorized coconut oil. Virgin coconut oil showed better antioxidant capacity than refined, bleached and deodorized coconut oil. The virgin coconut oil produced through the fermentation method had the strongest scavenging effect on 1,1-diphenyl-2-picrylhydrazyl and the highest antioxidant activity based on the beta-carotene-linoleate bleaching method. However, virgin coconut oil obtained through the chilling method had the highest reducing power. The major phenolic acids detected were ferulic acid and p-coumaric acid. Very high correlations were found between the total phenolic content and scavenging activity (r=0.91), and between the total phenolic content and reducing power (r=0.96). There was also a high correlation between total phenolic acids and beta-carotene bleaching activity. The study indicated that the contribution of antioxidant capacity in virgin coconut oil could be due to phenolic compounds.

  11. Virgin queen attraction toward males in honey bees.

    Bastin, Florian; Cholé, Hanna; Lafon, Grégory; Sandoz, Jean-Christophe

    2017-07-24

    Although the honeybee is a crucial agricultural agent and a prominent scientific model organism, crucial aspects of its reproductive behaviour are still unknown. During the mating season, honeybee males, the drones, gather in congregations 10-40 m above ground. Converging evidence suggests that drones emit a pheromone that can attract other drones, thereby increasing the size of the congregation. Virgin queens join the vicinity of the congregation after it has formed, and mate with as many as 20 males in mid-air. It is still unclear which sensory cues help virgin queens find drone congregations in the first place. Beside visual cues for long-range orientation, queens may use olfactory cues. We thus tested virgin queens' olfactory orientation on a walking simulator in which they have full control over odour stimulation. We show that sexually-mature virgin queens are attracted to the odour bouquet from a group of living drones. They are not attracted to the bouquet from a group of workers. In addition, non-sexually receptive females (workers) of the same age are not attracted to the drone odour bouquet. Interpreted in the context of mating, these results may suggest that virgin queens use volatile olfactory cues from the drones to find the congregations.

    2017-08-01

    The aim of this study examined the characterization of extra virgin olive oil samples from the main cultivar Chemlali, grown in five olive orchards with different soil type (Sandy, Clay, Stony, Brown, Limestone and Gypsum). Volatile compounds were studied using headspace-solid phase micro-extraction (HS-SPME) and gas chromatography-mass spectrometry (GC-MS) technics. Moreover, the sterol profile was established using gas chromatography-mass spectrometry. 35 different volatile compounds were identified: alcohols, esters, aldehydes, ketones and hydrocarbons. The chemical composition of the volatile fraction was characterized by the preeminence of 2-hexenal (32.75%) and 1-hexanol (31.88%). Three sterols were identified and characterized. For all olive oil samples, ß-sitosterol (302.25 mg/kg) was the most abundant sterol. Interestingly, our results showed significant qualitative and quantitative differences in the levels of the volatile compounds and sterols from oils obtained from olive trees grown in different soil type.

  2. Transforming feminine categories: genealogies of virginity and sainthood.

    Science.gov (United States)

    Stiritz, Susan E; Schiller, Britt-Marie

    2005-01-01

    The categories of virginity and sainthood, often used as norms of femininity, are historically and contextually constructed. Genealogies of these categories reveal definitions of female subjectivity in accordance with male desires. Traditional conceptions of virginity have implications for theories of female development and sexuality, conceptions of the psychoanalytic process, and theories of social symbolism. Notions of virginity as an unblemished state, the first penetration by a penis as an irrevocable transformation to womanhood, and defloration as a developmental milestone in female sexuality derive from male fantasies of female purity that translate into justifications for social structures of control and ownership. While fantasies of sainthood played significant roles in the work of both Sigmund and Anna Freud, their images of saints, which they did not analyze, were unconsciously shaped by a Victorian sensibility. Because the psychoanalytic legacy is androcentrically informed, analysts may be hampered in their efforts to treat the pathologies of perfection that continue to plague women. Contesting and unsettling conventional epistemological assumptions open up the categories of virginity and sainthood to images and representations of female autonomy and integrity. The critical analyses offered here contribute to theories of the plasticity of gender and the social construction of femininity.

    2010-01-01

    The Mediterranean diet is associated with a lower incidence of atherosclerosis, cardiovascular disease, neurodegenerative diseases and certain types of cancer. The apparent health benefits have been partially ascribed to the dietary consumption of virgin olive oil by Mediterranean populations. Much research has focused on the biologically active phenolic compounds naturally present in virgin olive oils to aid in explaining reduced mortality and morbidity experienced by people consuming a traditional Mediterranean diet. Studies (human, animal, in vivo and in vitro) have demonstrated that olive oil phenolic compounds have positive effects on certain physiological parameters, such as plasma lipoproteins, oxidative damage, inflammatory markers, platelet and cellular function, antimicrobial activity and bone health. This paper summarizes current knowledge on the bioavailability and biological activities of olive oil phenolic compounds. PMID:20386648

    2009-01-01

    As a result of the changes that occur during their use, used engine oils tend to differ in chemical and physical composition from a virgin oil. In general recycled oils have: much higher water and sediment levels than virgin oil; relatively higher concentrations of organic compounds (oxidation products); and relatively higher levels of metals such as Fe, Cd, Cr, Pb, etc. Therefore, the aim of this work was to investigate, assess and to observe, by means of the physical and the chemical properties of the oils, atomic absorption (AA), inductive couple plasma (ICP) and Fourier transform infrared (FTIR) analyses the extent of the differences occurring between the virgin and recycled oil. In important part of this work was also the development of analytical techniques based on the use of FTIR spectroscopy; in relation to the rapid analysis of lubricants; in particular for the differentiation of virgin and recycled oil. The results obtained were expected to be useful for differentiation purposes, providing information on whether the metal concentrations and oxidation products could be an appropriate feature for differentiating a particular oil sample from the others. This work is categorized into a two-step procedure. Firstly, an evaluation of a typical FTIR spectrum of an engine oil sample (mono- and multigrade) is presented. The broad feature centered at 1716 cm(-1) is due to the presence of carbonyl containing degradation products of oil. A band observed at 1732, 1169, 1154 and 1270 cm(-1) assigned to the polymethacrylate stretching vibrations, allows the determination of viscosity modifier and pour point depressant additives. The observed differences in the specific spectral bands (1732, 1169, 1154 and 1270 and 1716 cm(-1)) are investigated and discussed. Secondly, an analytical technique for the measurement of the levels of the wear metals is also applied.

  11. LauncherOne: Virgin Orbit's Dedicated Launch Vehicle for Small Satellites & Impact to the Space Enterprise Vision

    Science.gov (United States)

    Vaughn, M.; Kwong, J.; Pomerantz, W.

    Virgin Orbit is developing a space transportation service to provide an affordable, reliable, and responsive dedicated ride to orbit for smaller payloads. No longer will small satellite users be forced to make a choice between accepting the limitations of flight as a secondary payload, paying dramatically more for a dedicated launch vehicle, or dealing with the added complexity associated with export control requirements and international travel to distant launch sites. Virgin Orbit has made significant progress towards first flight of a new vehicle that will give satellite developers and operators a better option for carrying their small satellites into orbit. This new service is called LauncherOne (See the figure below). LauncherOne is a two stage, air-launched liquid propulsion (LOX/RP) rocket. Air launched from a specially modified 747-400 carrier aircraft (named “Cosmic Girl”), this system is designed to conduct operations from a variety of locations, allowing customers to select various launch azimuths and increasing available orbital launch windows. This provides small satellite customers an affordable, flexible and dedicated option for access to space. In addition to developing the LauncherOne vehicle, Virgin Orbit has worked with US government customers and across the new, emerging commercial sector to refine concepts for resiliency, constellation replenishment and responsive launch elements that can be key enables for the Space Enterprise Vision (SEV). This element of customer interaction is being led by their new subsidiary company, VOX Space. This paper summarizes technical progress made on LauncherOne in the past year and extends the thinking of how commercial space, small satellites and this new emerging market can be brought to bear to enable true space system resiliency.

  12. The evolutionary dynamics of adaptive virginity, sex-allocation, and altruistic helping in haplodiploid animals.

    Science.gov (United States)

    Rautiala, Petri; Helanterä, Heikki; Puurtinen, Mikael

    2018-01-01

    In haplodiploids, females can produce sons from unfertilized eggs without mating. However, virgin reproduction is usually considered to be a result of a failure to mate, rather than an adaptation. Here, we build an analytical model for evolution of virgin reproduction, sex-allocation, and altruistic female helping in haplodiploid taxa. We show that when mating is costly (e.g., when mating increases predation risk), virginity can evolve as an adaptive female reproductive strategy. Furthermore, adaptive virginity results in strongly divergent sex-ratios in mated and virgin queen nests ("split sex ratios"), which promotes the evolution of altruistic helping by daughters in mated queen nests. However, when helpers evolve to be efficient and increase nest production significantly, virgin reproduction is selected against. Our results suggest that adaptive virginity could have been an important stepping stone on the pathway to eusociality in haplodiploids. We further show that virginity can be an adaptive reproductive strategy also in primitively social haplodiploids if workers bias the sex ratio toward females. By remaining virgin, queens are free to produce sons, the more valuable sex in a female-biased population. Our work brings a new dimension to the studies linking reproductive strategies with social evolution. © 2017 The Author(s). Evolution © 2017 The Society for the Study of Evolution.

    The breeding soundness evaluation (BSE) was used to evaluate Senepol (Bos taurus) bulls (n = 495) on St. Croix over a 7-year period. Young, unproven bulls (10-26 months of age) and breeding bulls (16 months to 8.5 years) were tested prior to sale or use in breeding. Inbreeding coefficients were determined for a subset of bulls (n = 290). The percentage of bulls passing the BSE increased (P 20 months. The proportion of all bulls that failed the BSE and received an Unsatisfactory rating for scrotal circumference or sperm motility decreased (P 90 to Senepol bulls raised under tropical conditions had a low probability of passing the BSE at young ages, but the passing rate increased with age. Older Senepol bulls were more likely to fail the BSE due to abnormal sperm morphology than due to inadequate testicular size or sperm motility. To prevent unnecessary culling, a BSE should not be performed on Senepol bulls <16 months old.

  20. Research Opportunities on board Virgin Galactic's SpaceShipTwo

    Science.gov (United States)

    Attenborough, S.; Pomerantz, W.; Stephens, K.

    2013-09-01

    Virgin Galactic is building the world's first commercial spaceline. Our suborbital spaceflight system, pictured in Figure 1, consists of two vehicles: WhiteKnightTwo (WK2) and SpaceShipTwo (SS2). WhiteKnightTwo is a four-engine, dual-fuselage jet aircraft capable of high-altitude heavy lift missions, including, but not limited to fulfilling its role as a mothership for SpaceShipTwo, an air-launched, suborbital spaceplane capable of routinely reaching an apogee up to 110 kilometers. In conjunction, these two vehicles allow access to space and to regions of the atmosphere ranging from the troposphere to the thermosphere; additionally, they provide extended periods of microgravity in a reliable and affordable way. SpaceShipTwo, with a payload capacity of up to 1,300 lbs. (~600 kg), features payload mounting interfaces that are compatible with standard architectures such as NASA Space Shuttle Middeck Lockers, Cargo Transfer Bags, and server racks, in addition to custom structures. With the standard interface, payloads are allowed access to the large 17 inch diameter cabin windows for external observations. Each dedicated research flight will be accompanied by a Virgin Galactic Flight Test Engineer, providing an opportunity for limited in-flight interaction. In addition, tended payloads - a flight that includes the researcher and his or her payload - are also an option. At a price point that is highly competitive with parabolic aircraft and sounding rockets and significantly cheaper than orbital flights, SpaceShipTwo is a unique platform that can provide frequent and repeatable research opportunities. Suborbital flights on SpaceShipTwo offer researchers several minutes of microgravity time and views of the external environment in the upper atmosphere and in outer space. In addition to serving as an important research platform in and of itself, SpaceShipTwo also offers researchers a means to test, iterate, and calibrate experiments designed for orbital platforms

    Virgin coconut oil, rich in antioxidants, was shown to attenuate hypertension. This study aimed to investigate the effects of virgin coconut oil on blood pressure and related parameters in kidneys in rats fed with 5-times-heated palm oil (5HPO). Thirty-two male Sprague-Dawley rats were divided into 4 groups. Two groups were fed 5HPO (15%) diet and the second group was also given virgin coconut oil (1.42 mL/kg, oral) daily for 16 weeks. The other 2 groups were given basal diet without (control) and with virgin coconut oil. Systolic blood pressure was measured pre- and post-treatment. After 16 weeks, the rats were sacrificed and kidneys were harvested. Dietary 5HPO increased blood pressure, renal thiobarbituric acid reactive substance (TBARS), and nitric oxide contents, but decreased heme oxygenase activity. Virgin coconut oil prevented increase in 5HPO-induced blood pressure and renal nitric oxide content as well as the decrease in renal heme oxygenase activity. The virgin coconut oil also reduced the elevation of renal TBARS induced by the heated oil. However, neither dietary 5HPO nor virgin coconut oil affected renal histomorphometry. In conclusion, virgin coconut oil has a potential to reduce the development of hypertension and renal injury induced by dietary heated oil, possibly via its antioxidant protective effects on the kidneys.

    To investigate the absorption of tyrosol and hydroxytyrosol from moderate and sustained doses of virgin olive oil consumption. The study also aimed to investigate whether these phenolic compounds could be used as biomarkers of virgin olive oil intake. Ingestion of a single dose of virgin olive oil (50 ml). Thereafter, for a week, participants followed their usual diet which included 25 ml/day of the same virgin olive oil as the source of raw fat. Unitat de Recerca en Farmacologia. Institut Municipal d'Investigació Mèdica (IMIM). Seven healthy volunteers. An increase in 24 h urine of tyrosol and hydroxytyrosol, after both a single-dose ingestion (50 ml) and short-term consumption (one week, 25 ml/day) of virgin olive oil (P<0.05) was observed. Urinary recoveries for tyrosol were similar after a single dose and after sustained doses of virgin olive oil. Mean recovery values for hydroxytyrosol after sustained doses were 1.5-fold those obtained after a single 50 ml dose. Tyrosol and hydroxytyrosol are absorbed from realistic doses of virgin olive oil. With regard to the dose-effect relationship, 24 h urinary tyrosol seems to be a better biomarker of sustained and moderate doses of virgin olive oil consumption than hydroxytyrosol.

    Full Text Available In 2010-2011, the Vancouver Island Transgender Needs Assessment, a community-based, applied research project, sought to identify the health and social needs of trans people on Vancouver Island, British Columbia, Canada. An advisory board consisting of trans-identified community members and trans-service providers guided this descriptive analysis. A total of 54 individuals identifying as transgender participated in a survey modeled after the TransPULSE Ontario instrument. Of the participants, 43% identified on the transmasculine spectrum, 39% on the transfeminine spectrum, and 18% as transgender/genderqueer only. Participants were surveyed in regard to education, employment, and income; housing; health care needs and services; suicidality; violence; life satisfaction and attitudes toward self; posttransition experiences; and community belonging. They reported health care, social support, and public education/acceptance as top needs. The article concludes with a specific needs profile and a community-generated set of recommendations stressing the need for an island-based information and resourcing center.

  8. Chemometric applications to assess quality and critical parameters of virgin and extra-virgin olive oil. A review.

    Science.gov (United States)

    Gómez-Caravaca, Ana M; Maggio, Rubén M; Cerretani, Lorenzo

    2016-03-24

    Today virgin and extra-virgin olive oil (VOO and EVOO) are food with a large number of analytical tests planned to ensure its quality and genuineness. Almost all official methods demand high use of reagents and manpower. Because of that, analytical development in this area is continuously evolving. Therefore, this review focuses on analytical methods for EVOO/VOO which use fast and smart approaches based on chemometric techniques in order to reduce time of analysis, reagent consumption, high cost equipment and manpower. Experimental approaches of chemometrics coupled with fast analytical techniques such as UV-Vis spectroscopy, fluorescence, vibrational spectroscopies (NIR, MIR and Raman fluorescence), NMR spectroscopy, and other more complex techniques like chromatography, calorimetry and electrochemical techniques applied to EVOO/VOO production and analysis have been discussed throughout this work. The advantages and drawbacks of this association have also been highlighted. Chemometrics has been evidenced as a powerful tool for the oil industry. In fact, it has been shown how chemometrics can be implemented all along the different steps of EVOO/VOO production: raw material input control, monitoring during process and quality control of final product.

    Full Text Available The aim of this work was to investigate the microencapsulation efficiency (MEE of different grades of broken rice (RB and breadfruit (BB-based maltodextrin as a coating material, using virgin coconut oil (VCO as a model system. The VCO was generally found to be well microencapsulated using BB, RB or commercial (COM maltodextrin at a core/wall material ratio of 1:3. In comparison to a different dextrose equivalent (DE group, both RB and BB maltodextrins with DE values of 10-14 showed higher MEE values (84.81-94.39% than maltodextrins with DE value of 15-19 (78.23-79.65%. Low DE value maltodextrins were shown higher glass transition temperatures than high DE value maltodextrins under the same moisture content. Both RB and BB maltodextrins were found to be compatible with COM maltodextrin as shown in the microstructure appearance when viewed with a scanning electron microscope (SEM.

  14. The Health Benefiting Mechanisms of Virgin Olive Oil Phenolic Compounds

    Directory of Open Access Journals (Sweden)

    Lisa Parkinson

    2016-12-01

    Full Text Available Virgin olive oil (VOO is credited as being one of the many healthful components associated with the Mediterranean diet. Mediterranean populations experience reduced incidence of chronic inflammatory disease states and VOO is readily consumed as part of an everyday Mediterranean dietary pattern. VOO is rich in phenolic compounds and the health promoting benefits of these phenolics are now established. Recent studies have highlighted the biological properties of VOO phenolic compounds elucidating their anti-inflammatory activities. This paper will review current knowledge on the anti-inflammatory and nutrigenomic, chemoprotective and anti-atherosclerotic activities of VOO phenolics. In addition the concentration, metabolism and bioavailability of specific phenolic compounds will be discussed. The evidence presented in the review concludes that oleurepein, hydroxytyrosol and oleocanthal have potent pharmacological activities in vitro and in vivo; however, intervention studies with biologically relevant concentrations of these phenolic compounds are required.

  15. Rapid NIR determination of alkyl esters in virgin olive oil

    2017-06-01

    Full Text Available The regulation of The European Union for olive oil and olive pomace established the limit of 35 mg·kg-1 for fatty acids ethyl ester contents in extra virgin olive oils, from grinding seasons after 2016. In this work, predictive models have been established for measuring fatty acid ethyl and methyl esters and to measure the total fatty acid alkyl esters based on near infrared spectroscopy (NIRS, and used successfully for this purpose. The correlation coefficients from the external validation exercises carried out with these predictive models ranged from 0.84 to 0.91. Different classification tests using the same models for the thresholds 35 mg·kg-1 for fatty acid ethyl esters and 75 mg·kg-1 for fatty acid alkyl esters provided success percentages from 75.0% to 95.2%.

  16. Island Demography: A Review of Selected Caribbean Contributions

    Directory of Open Access Journals (Sweden)

    McElroy, Jerome L.

    2011-11-01

    Full Text Available This article traces the demographic contributions of island studies scholarship in four sections. First, demographic transition theory is applied to the population history of the region. The second highlights the impact of this demographic scholarship on related social science fields in the Caribbean. The third and fourth contributions focus on the impact of migration on two related hypotheses: the demographic transition and the mobility transition. In the first case, migration patterns between St. Kitts-Nevis and the U.S. Virgin Islands in the 1960s suggest that the age-sex selectivity of migration tends to accelerate the transition in sending societies and retard its progress in receiving societies. In the second case, empirical support is provided for the so-called ‘migration transition’ whereby former chronic labour exporters become labour importers under sustained growth.

  17. Characterization of virgin olive oils produced with autochthonous Galician varieties.

    The interest of Galician oil producers (NW Spain) in recovering the ancient autochthonous olive varieties Brava and Mansa has increased substantially in recent years. Virgin olive oils produced by co-crushing both varieties in two different proportions, reflecting the usual and most common practice adopted in this region, have gradually emerged for the production of virgin olive oils. Herein, the sensory and chemical characteristics of such oils were characterized by quality and genuineness-related parameters. The results of chemical analysis are discussed in terms of their effective contribution to the sensory profile, which suggests useful recommendations for olive oil producers to improve the quality of oils. Antioxidant compounds, together with aromas and coloured pigments were determined, and their contribution in determining the functional value and the sensory properties of oils was investigated. In general, given the high levels of phenolic compounds (ranging between 254 and 375mg/kg oil), tocopherols (about 165mg/kg oil) and carotenoids (10-12mg/kg oil); these are oils with long stability, especially under dark storage conditions, because stability is reinforced with the contribution of chlorophylls (15-22mg/kg oil). A major content of phenolic compounds, as well as a predominance of trans-2-hexen-1-al within odor-active compounds (from 897 to 1645μg/kg oil), responsible for bitter sensory notes. This characterization allows to developing new antioxidant-rich and flavour-rich VOOs, when co-crushing with a higher proportion of Brava olives, satisfying the consumers' demand in having access to more healthy dishes and peculiar sensory attributes.

    In the fire ant Solenopsis invicta, sexually mature virgin females are prevented from shedding their wings and becoming functional egg layers by the presence of the mated queen. Experimental data suggest that this inhibitory effect results from the action of a relatively nonvolatile primer pheromone (or pheromones) produced by the mated queen and distributed by the workers. Target ants are both virgin queens and workers.

    Adulteration of extra virgin olive oil with sunflower oil is a major issue for the olive oil industry. In this paper, the potential of total synchronous fluorescence (TSyF) spectra to differentiate virgin olive oil from sunflower oil and synchronous fluorescence (SyF) spectra combined with multivariate analysis to assess the adulteration of virgin olive oil are demonstrated. TSyF spectra were acquired by varying the excitation wavelength in the region 270-720 nm and the wavelength interval (Deltalambda) in the region from 20 to 120 nm. TSyF contour plots for sunflower, in contrast to virgin olive oil, show a fluorescence region in the excitation wavelength range 325-385 nm. Fifteen different virgin olive oil samples were adulterated with sunflower oil at varying levels (0.5-95%) resulting in one hundred and thirty six mixtures. The partial least-squares regression model was used for quantification of the adulteration using wavelength intervals of 20 and 80 nm. This technique is useful for detection of sunflower oil in virgin olive oil at levels down to 3.4% (w/v) in just two and a half minutes using an 80-nm wavelength interval.

    Full Text Available Plastix A/S is a Danish cleantech company transforming discarded fishing trawls and nets into valuable green raw materials. Plastix– technology and processes solve a maritime waste problem and contribute to a more circular green economy and reduce landfilling, marine pollution, CO2 emissions and especially loss of valuable resources. Plastix– recycling technology enables recovery of discarded fishing trawls and nets via mechanical and thermal processes transforming the waste into valuable recycles which can be converted into plastic products replacing virgin raw materials. The performance has been proved through a Life Cycle Assessment (LCA study. The results from the LCA study are compared with the production of virgin materials. The results of the LCA show that especially the carbon footprint is remarkable better for Oceanix than for virgin plastics. Oceanix HDPE is 5 times better than virgin HDPE, when talking about the carbon foot print, and the results for Oceanix PP and Oceanix PA6 are 5 times and 20 times better compared with virgin PP and PA6. Also other environmental indicators are better for Oceanix compared with virgin plastics.

    It is well established that extra virgin olive oil (EVOO), applied to the skin, has healing and anti-inflammatory properties. To evaluate the effectiveness of EVOO in the prevention of nipple cracking in lactating women. Experimental, prospective, randomized study of 300 lactating women, admitted to the postpartum unit of the city's general hospital (Cienfuegos, Cuba). The study was carried out in 2012. Eligible patients were randomized into two groups of 150 women. In Group 1, EVOO was applied on the nipple after feeding, and in Group 2, drops of breast milk were applied to the nipple after feeding. Clinical evaluations were made during the first week of treatment and after the first month. All women who initiated breastfeeding were considered eligible to be included in this study; breastfeeding was characterized as the moment of mother-child interaction with suction on the nipple. Efficacy was evaluated quantitatively, as the absence of cracks in the nipple during the first 2 weeks of lactation using as the proportion of women with or without nipple cracks, and if present, whether they were moderate or slight. The quantitative efficacy was 97.3% and no adverse effects occurred in mothers and newborns during the administration of EVOO. EVOO helps prevent nipple cracking in lactating women. It has been shown to have protective effects when breastfeeding presents technical difficulties. This conclusion is borne out by the frequency distribution results obtained, which reflect a significantly higher proportion of nipple cracking in the population that was not treated with EVOO. Use EVOO to prevent nipple cracking during breastfeeding by administering 3 drops on each nipple after each feeding. Decreased nipple cracking will reduce pain and enhance breastfeedinging by administering 3 drops on each nipple after each feeding, improving the health of mothers and infants. © 2015 Sigma Theta Tau International.

    The importance of olive polyphenols as bioactive compounds has grown in recent years as a result of intensive research on their anticancer, antiatherosclerotic and antihypertensive activities. However, there is currently no official method for determining the content of polyphenols in olive oils because of the technical difficulties in their determination. Here a simple method for the analysis of extra virgin olive oil o-diphenols by visible spectrometry is proposed and compared with the traditional method of solid phase extraction followed by colorimetric determination using sodium molybdate or Folin-Ciocalteu reagent or by high-performance liquid chromatography (HPLC) analysis using UV detection. This new approach to determining total o-diphenolic compounds exploits the oxidation of o-diphenols to quinones in a basic medium. Preliminary results showed a better correlation between the total o-diphenol determination by HPLC and by the proposed method (R(2) = 0.9229) than between the total o-diphenol determination by HPLC and by the molybdate colorimetric method (R(2) = 0.8689). A good correlation was also observed between the total phenolic content determined by HPLC and by the proposed method (R(2) = 0.8196), but this correlation was a little lower than the one obtained between the HPLC method and the Folin-Ciocalteu method (R(2) = 0.8752). The proposed method involves very little sample manipulation, requires inexpensive reagents and can be performed in less than 40 min for several samples at the same time, using olive oil samples of only 1-2 g. © 2012 Society of Chemical Industry.

    Virginity is part of our existence in the world as embodied sexual subjects. While many meanings are associated with virginity, in most of the Arab world virginity relates to the presence of a hymen and extends to encompass the honor of the Arab community, and virginity loss commonly relate to first vaginal intercourse. This study explored the meanings of virginity from the perspectives of Arab and Arab American women. A qualitative phenomenological approach, informed by the philosophy of Maurice Merleau-Ponty, was used to conduct in-depth interviews with ten women. We identified one over-arching theme Virginity as Identity, and two major themes Embodiment of Virginity and “We are Arabs.” To reach an embodied virginity, participants went through a disembodied virginity process, reflecting society’s perceptions and values of virginity related to anatomical presence of a hymen and society’s honor. “We are Arabs” describes the ways women identified with the Arab ethnic identity as a shared overall identification, but differed from one lived experience to another, and influenced how participants embodied virginity. Our participants provided a better understanding of the diverse meanings of virginity that move beyond the binary of virginity and virginity loss, and into a spectrum of embodied meanings. Findings suggest the need for future research around sexuality in Arab Americans with attention to socio-political contexts in order to understand the nature and context of sexual initiation and its impact on sexual behaviors and well-being.

    Operational Experience At the end of the first full-year running period of LHC, CMS is established as a reliable, robust and mature experiment. In particular common systems and infrastructure faults accounted for <0.6 % CMS downtime during LHC pp physics. Technical operation throughout the entire year was rather smooth, the main faults requiring UXC access being sub-detector power systems and rack-cooling turbines. All such problems were corrected during scheduled technical stops, in the shadow of tunnel access needed by the LHC, or in negotiated accesses or access extensions. Nevertheless, the number of necessary accesses to the UXC averaged more than one per week and the technical stops were inevitably packed with work packages, typically 30 being executed within a few days, placing a high load on the coordination and area management teams. It is an appropriate moment for CMS Technical Coordination to thank all those in many CERN departments and in the Collaboration, who were involved in CMS techni...

    Operational Experience Since the closure of the detector in February, the technical operation of CMS has been quite smooth and reliable. Some minor interventions in UXC were required to cure failures of power supplies, fans, readout boards and rack cooling connections, but all these failures were repaired in scheduled technical stops or parasitically during access dedicated to fixing LHC technical problems. The only occasion when CMS had to request an access between fills was to search for the source of an alarm from the leak-detection cables mounted in the DT racks. After a few minutes of diagnostic search, a leaking air-purge was found. Replacement was complete within 2 hours. This incident demonstrated once more the value of these leak detection cables; the system will be further extended (during the end of year technical stop) to cover more racks in UXC and the floor beneath the detector. The magnet has also been operating reliably and reacted correctly to the 14s power cut on 29 May (see below). In or...

  14. Some nutritional benefits of extra virgin olive oil

    Directory of Open Access Journals (Sweden)

    Testolin, G.

    1994-04-01

    Full Text Available The benefits of olive oil could be related to its antioxidant potential. The aim of this study was to evaluate the "in vivo" antioxidant activity of different extra virgin olive oils (EVOO produced in the Mediterranean area. One hundred and twenty rats were fed diets containing oxidised and refined olive oil (400 mEq O2 kg for 11 weeks, a period of time sufficient to induce globular fragility and marginal plasma tocopherols deficiency.
    The animals were then fed 5 diets containing EVOO with content of tocopherols and phenols ranging from 165 to 335 and from 62 to 389 ppm respectively, in different tocopherols/phenols ratios, for 4 weeks. Results show that plasma tocopherols concentration after EVOO feeding was directly related to dietary intake.
    Moreover, globular resistance improved to a different extent with EVOO diets compared to the oxidised oil diet. The most favourable antioxidant response was obtained by feeding the oil high in both tocopherols and phenols; the action of phenols was considered synergetic to that of tocopherols in restoring normal conditions, impaired by the oxidised oil diet.

    The aim of this chapter is to provide a brief overview of the recent results of studies on extra virgin olive oil (EVOO) and its interactions with other food ingredients during cooking, to highlight basic molecular aspects of the "magic" of EVOO and its role in Mediterranean gastronomy. The use of raw EVOO added to foods after cooking (or as a salad oil) is the best way to express the original flavour and to maximize the intake of natural antioxidants and compounds related to positive effects on human health (hypotensive, anti-inflammatory, and anti-cancerogenic, among others). EVOO, however, also exhibits its protective properties during/after cooking. Different chemical interactions between biophenolic compounds and other food ingredients (water, milk proteins, carotenoids of tomato, omega-3 polyunsaturated fatty acids in canned-in-oil fish and meat or fish proteins) occur. Even during cooking, EVOO exhibits strong antioxidant properties and influences the overall flavour of cooked foods. The physical (partitioning, emulsion) and chemical (hydrolysis, covalent binding, antioxidant properties) phenomena occurring during cooking of EVOO are discussed with emphasis on the changes in the sensory (bitterness and fruity flavour) and nutritional qualities of some traditional Mediterranean foods. In particular, tomato-oil interactions during cooking, fish canning in EVOO, meat marinated in EVOO before cooking and roasting and frying in EVOO are examined. The interactions between EVOO antioxidants and flavours with milk proteins are also briefly discussed.

    Full Text Available Over the last few decades, multiple biological properties, providing antioxidant, anti-inflammatory, chemopreventive and anti-cancer benefits, as well as the characteristic pungent and bitter taste, have been attributed to Extra Virgin Olive Oil (EVOO phenols. In particular, growing efforts have been devoted to the study of the antioxidants of EVOO, due to their importance from health, biological and sensory points of view. Hydrophilic and lipophilic phenols represent the main antioxidants of EVOO, and they include a large variety of compounds. Among them, the most concentrated phenols are lignans and secoiridoids, with the latter found exclusively in the Oleaceae family, of which the drupe is the only edible fruit. In recent years, therefore, we have tackled the study of the main properties of phenols, including the relationships between their biological activity and the related chemical structure. This review, in fact, focuses on the phenolic compounds of EVOO, and, in particular, on their biological properties, sensory aspects and antioxidant capacity, with a particular emphasis on the extension of the product shelf-life.

    Virgin coconut oil (VCO) has been consumed worldwide for various health-related reasons and some of its benefits have been scientifically evaluated. Medium-chain fatty acids were found to be a potential antidepressant functional food; however, this effect had not been evaluated in VCO, which is rich in polyphenols and medium-chain fatty acids. The aim of this study was to evaluate the antistress and antioxidant effects of VCO in vivo , using mice with stress-induced injury. The antistress effect of VCO (administered per os , at a dose of 10 ml/kg body weight) was evaluated using the forced swim test and chronic cold restraint stress models. VCO was able to reduce immobility time and restore oxidative stress in mice post-swim test. Furthermore, mice treated with VCO were found to exhibit higher levels of brain antioxidants, lower levels of brain 5-hydroxytryptamine and reduced weight of the adrenal glands. Consequently, the serum cholesterol, triglyceride, glucose and corticosterone levels were also lower in VCO-treated mice. These results suggest the potential value of VCO as an antistress functional oil.

    The nutritional benefits generally recognized for the consumption of extra virgin olive oil (EVOO) are based on a large number of dietary trials of several international populations and intervention studies. Unfortunately, many authors in this field used questionable analytical methods and commercial kits that were not validated scientifically to evaluate the complex bioactive constituents of EVOO and lipid oxidation and decomposition products. Many questionable antiradical methods were commonly used to evaluate natural polyphenolic antioxidants, including an indirect method to determine low-density lipoprotein (LDL) cholesterol. Extensive differences were observed in experimental design, diet control, populations of different ages and problems of compliance intervention, and questionable biomarkers of oxidative stress. Analyses in many nutritional studies were limited by the use of one-dimensional methods to evaluate multifunctional complex bioactive compounds and plasma lipid profiles by the common applications of commercial kits. Although EVOO contains polyphenolic compounds that exhibit significant in vitro antioxidant activity, much more research is needed to understand the absorption and in vivo activity. Many claims of in vivo human beneficial effects by the consumption of EVOO may be overstated. No distinctions were apparently made between in vivo studies based on general health effects in large populations of human subjects and smaller scale well-controlled feeding trials using either pure or mixtures of known phenolic constituents of EVOO. More reliable protocols and testing methods are needed to better validate the complex nutritional properties of EVOO.

    Turkish extra virgin olive oils (EVOO) from different varieties/geographical origins and their phenolic compounds were investigated in terms of their antimicrobial and antioxidant properties in comparison to refined olive, hazelnut, and canola oils. Antimicrobial activity was tested against three foodborne pathogenic bacteria, Escherichia coli O157:H7, Listeria monocytogenes , and Salmonella Enteritidis. Although all EVOOs showed a bactericidal effect, the individual phenolic compounds demonstrated only slight antimicrobial activity. Moreover, refined oil samples did not show any antimicrobial activity. Among the phenolic compounds, cinnamic acid (2 mg/kg of oil) had the highest percent inhibition value with 0.25 log reduction against L. monocytogenes. The synergistic interactions of tyrosol, vanillin, vanillic, and cinnamic acids were also observed against Salmonella Enteritidis. The antioxidant activities of oils were tested by beta-carotene-linoleate model system and ABTS method. In both methods, EVOOs showed higher antioxidant activities, whereas refined oils had lower activity. The ABTS method provided a higher correlation (0.89) with total phenol content.

    Full Text Available The prevalence of striae gravidarum (SG in pregnant women ranges from 50% to 90%. Effects of SG include itchy and hot feeling as well as dry skin. This situation also causes emotional disturbances that poses a cosmetic problem for most pregnant women. Nowadays, many pregnant women use olive oil to prevent SG, but it is relatively difficult to find and costly. In Indonesia, a similar oil, virgin coconut oil (VCO, has been used by many pregnant women for the same reason. The aim of this study was to analyze the differences and correlation between effects of olive oil and VCO against SG. The study was conducted in March−July 2012. An experimental study was performed on 80 pregnant women in Surabaya Municipality and they were divided into 2 groups using random permuted blocks. The results of this study showed that there was no difference in SG appearance based on the number of lines and levels of erythema between groups (p=0.156 and 1.00. Furthermore, there was a strong negative correlation between the effect of olive oil or VCO on the number of lines (r=-0.576 and -0.560 and the level of erythema (r=-0.699 and -0.586. In conclusion, there is no difference in the effect of olive oil and VCO against SG.

    Full Text Available PURPOSE: To determine the measurement reliability of CorVis ST, a dynamic Scheimpflug analyser, in virgin and post-photorefractive keratectomy (PRK eyes and compare the results between these two groups. METHODS: Forty virgin eyes and 42 post-PRK eyes underwent CorVis ST measurements performed by two technicians. Repeatability was evaluated by comparing three consecutive measurements by technician A. Reproducibility was determined by comparing the first measurement by technician A with one performed by technician B. Intraobserver and interobserver intraclass correlation coefficients (ICCs were calculated. Univariate analysis of covariance (ANCOVA was used to compare measured parameters between virgin and post-PRK eyes. RESULTS: The intraocular pressure (IOP, central corneal thickness (CCT and 1st applanation time demonstrated good intraobserver repeatability and interobserver reproducibility (ICC ≧ 0.90 in virgin and post-PRK eyes. The deformation amplitude showed a good or close to good repeatability and reproducibility in both groups (ICC ≧ 0.88. The CCT correlated positively with 1st applanation time (r = 0.437 and 0.483, respectively, p<0.05 and negatively with deformation amplitude (r = -0.384 and -0.375, respectively, p<0.05 in both groups. Compared to post-PRK eyes, virgin eyes showed longer 1st applanation time (7.29 ± 0.21 vs. 6.96 ± 0.17 ms, p<0.05 and lower deformation amplitude (1.06 ± 0.07 vs. 1.17 ± 0.08 mm, p < 0.05. CONCLUSIONS: CorVis ST demonstrated reliable measurements for CCT, IOP, and 1st applanation time, as well as relatively reliable measurement for deformation amplitude in both virgin and post-PRK eyes. There were differences in 1st applanation time and deformation amplitude between virgin and post-PRK eyes, which may reflect corneal biomechanical changes occurring after the surgery in the latter.

The detector is fully closed with all components operational and the magnetic field is normally at the nominal 3.8T. The UXC cavern is normally closed with the radiation veto set. Access to UXC is now only possible during downtimes of LHC. Such accesses must be carefully planned, documented and carried out in agreement with CMS Technical Coordination, Experimental Area Management, LHC programme coordination and the CCC. Material flow in and out of UXC is now strictly controlled. Access to USC remains possible at any time, although, for safety reasons, it is necessary to register with the shift crew in the control room before going down.It is obligatory for all material leaving UXC to pass through the underground buffer zone for RP scanning, database entry and appropriate labeling for traceability.

    Full Text Available Virgin olive oil, the main fat of the Mediterranean diet, is per se considered as a functional food—as stated by the European Food Safety Authority (EFSA—due to its content in healthy compounds. The daily intake of endogenous bioactive phenolics from virgin olive oil is variable due to the influence of multiple agronomic and technological factors. Thus, a good strategy to ensure an optimal intake of polyphenols through habitual diet would be to produce enriched virgin olive oil with well-known bioactive polyphenols. Different sources of natural biological active substances can be potentially used to enrich virgin olive oil (e.g., raw materials derived from the same olive tree, mainly olive leaves and pomaces, and/or other compounds from plants and vegetables, mainly herbs and spices. The development of these functional olive oils may help in prevention of chronic diseases (such as cardiovascular diseases, immune frailty, ageing disorders and degenerative diseases and improving the quality of life for many consumers reducing health care costs. In the present review, the most relevant scientific information related to the development of enriched virgin olive oil and their positive human health effects has been collected and discussed.

    The Virgin River contributes a substantial amount of dissolved solids (salt) to the Colorado River at Lake Mead in the lower Colorado River Basin. Degradation of Colorado River water by the addition of dissolved solids from the Virgin River affects the suitability of the water for municipal, industrial, and agricultural use within the basin. Dixie Hot Springs in Utah are a major localized source of dissolved solids discharging to the Virgin River. The average measured discharge from Dixie Hot Springs during 2009–10 was 11.0 cubic feet per second (ft3/s), and the average dissolved-solids concentration was 9,220 milligrams per liter (mg/L). The average dissolved-solids load—a measurement that describes the mass of salt that is transported per unit of time—from Dixie Hot Springs during this period was 96,200 tons per year (ton/yr). Annual dissolved-solids loads were estimated at 13 monitoring sites in the Virgin River Basin from streamflow data and discrete measurements of dissolved-solids concentrations and (or) specific conductance. Eight of the sites had the data needed to estimate annual dissolved-solids loads for water years (WYs) 1999 through 2010. During 1999–2010, the smallest dissolved-solids loads in the Virgin River were upstream of Dixie Hot Springs (59,900 ton/yr, on average) and the largest loads were downstream of Littlefield Springs (298,200 ton/yr, on average). Annual dissolved-solids loads were smallest during 2002–03, which was a period of below normal precipitation. Annual dissolved-solids loads were largest during 2005—a year that included a winter rain storm that resulted in flooding throughout much of the Virgin River Basin. An average seepage loss of 26.7 ft3/s was calculated from analysis of monthly average streamflow from July 1998 to September 2010 in the Virgin River for the reach that extends from just upstream of the Utah/Arizona State line to just above the Virgin River Gorge Narrows. Seepage losses from three river reaches

    2014-01-01

    The detection of adulteration in edible oils is a concern in the food industry, especially for the higher priced virgin olive oils. This article presents a low field unilateral nuclear magnetic resonance (NMR) method for the detection of the adulteration of virgin olive oil that can be performed through sealed bottles providing a non-destructive screening technique. Adulterations of an extra virgin olive oil with different percentages of sunflower oil and red palm oil were measured with a commercial unilateral instrument, the profile NMR-Mouse. The NMR signal was processed using a 2-dimensional Inverse Laplace transformation to analyze the transverse relaxation and self-diffusion behaviors of different oils. The obtained results demonstrated the feasibility of detecting adulterations of olive oil with percentages of at least 10% of sunflower and red palm oils. PMID:24469355

    Full Text Available Monovarietal virgin olive oils (VOOs are very effective to study relationships among sensory attributes, the compounds responsible for flavour, and factors affecting them. The stimulation of the human sensory receptors by volatile and non-volatile compounds present in monovarietal virgin olive oils gives rise to the sensory attributes that describe their peculiar delicate and fragrant flavours. The formation of these compounds is briefly illustrated and the influence of the agronomic and technological factors that affect their concentrations in the oil is examined. The relationships between compounds responsible for the olive oil flavour and sensory attributes are discussed. Several approaches for the varietal differentiation of monovarietal virgin olive oils are also overviewed.

    2015-03-15

    The effect of modifying polyphenol oxidase (PPO) and peroxidase (POX) activity during the extraction of virgin olive oil has been assessed in terms of its influence on the phenolic profile of the oil produced. These enzymes were modified by adding exogenous enzyme or specific inhibitors during the milling and subsequent kneading step, studying the effect on specific phenolic compounds in the oils. PPO is the main enzyme involved in phenolic oxidation at the milling step whereas POX activity seems to be the main influence during the kneading step. The data obtained suggest it is possible to increase the nutritional and organoleptic quality of virgin olive oil by inhibiting these enzymes during olive fruit processing. Treatment with the PPO inhibitor tropolone produced a twofold increase in the phenolic fraction, which would therefore seem to be an interesting strategy to improve the nutritional and organoleptic properties of virgin olive oil.

    Oleocanthal is one of the phenolic compounds of extra virgin olive oil with important anti-inflammatory properties. Although its potential anticancer activity has been reported, only limited evidence has been provided in cutaneous malignant melanoma. The present study is aimed at investigating the selective in vitro antiproliferative activity of oleocanthal against human malignant melanoma cells. Since oleocanthal is not commercially available, it was obtained as a pure standard by direct extraction and purification from extra virgin olive oil. Cell viability experiments carried out by WST-1 assay demonstrated that oleocanthal had a remarkable and selective activity for human melanoma cells versus normal dermal fibroblasts with IC50s in the low micromolar range of concentrations. Such an effect was paralleled by a significant inhibition of ERK1/2 and AKT phosphorylation and downregulation of Bcl-2 expression. These findings may suggest that extra virgin olive oil phenolic extract enriched in oleocanthal deserves further investigation in skin cancer.

    2012-04-01

    Full Text Available Women and health are two very close issues as family health lies most often in the hands of women. Ironically, their awareness toward their own health is still low. Cultural constraints have made single, unmarried women or virgins feel reluctant to go to obgyn clinics, though there is an increasing prevalence of cervical cancer in Indonesia. Related to the role of the media to reduce the number of women with cervical cancer, a question rises. How do the media represent this conflict? The object of the study is a documentary film about several problems faced by women. The unit of analysis is the episode that contains issues related to the virtue of virginity, and data were collected through an analysis of the media text. The findings show that the media seem to have an awareness of the problems, but they have not fully adopted gender perspectives, and this leads to the strengthening of myths, taboos and traditional values surrounding virginity.

    This study determined the prevalence and risk factors for genital human papillomavirus (HPV) detection among men who deny ever engaging in penetrative sex. A questionnaire was administered to 4123 men from a cohort study of HPV natural history. Genital exfoliated cells were collected and genotyped for 36 HPV types. Eighty-eight men were classified as virgins. Log-binomial regression models identified factors associated with genital HPV detection. The prevalence of any and high-risk HPV types among 88 male virgins was 25.0% and 18.2%, respectively. Age and smoking status were associated with HPV detection. Further studies are needed to better understand the risk for HPV infection among male virgins. © The Author 2016. Published by Oxford University Press for the Infectious Diseases Society of America.

    For the reporting period, the CMS common systems and infrastructure worked well, without failures that caused significant data losses. One more disconnection of the magnet cold box occurred in the shadow of interruptions in data taking, caused by a series of technical faults. The recognition during 2012 that re-connection can only safely be done at around 2 T implies a minimum magnet recovery time of 12 hours and raises serious concerns about the number of ramping cycles of the magnet these incidents cause. This has triggered studies of how to make the cryo-system of the magnet more robust against failures. The proton-proton run ended just before the end-of-year CERN closure, during which CASTOR was installed on the negative end of CMS and both ZDC calorimeters were installed in TAN absorbers the LHC tunnel, in preparation for the heavy-ion run. The installation of CASTOR was an excellent “engineering test” of procedures for working in an activated environment. Despite some technical pr...

      Operational experience 2011 CMS is approaching the end of a very successful year of operation. Proton- proton running ended in the late afternoon of 30th October with a stunning 5.73 fb–1 delivered by LHC, of which CMS recorded 5.22 fb–1. During heavy-ion operation, which continues until 7th December, both the accelerator and the CMS detector have also performed very well. Despite the encouraging overall reliability of technical operation, several infrastructure failures which occurred since the last Bulletin are worthy of mention, with one leading for the first time to significant data-loss. On 10th July, a CERN-wide power failure brought down essentially all services including the magnet, due to an MCS setting being left in “manual” after the recent technical stop, but there was no significant damage and the detector was operational before the LHC, despite a slow and tortuous recovery (one of several indications this year that there is room for improve...

    Summary of progress since last CMS week. Ten years of construction work have been completed. CMS is closed, in very close to the ideal low luminosity configuration, and performed well in the first tests with LHC beam. Behind this encouraging news is the story of a summer of intense commitment by many teams (from the collaboration and 3 CERN departments) working together, against the clock and despite many minor setbacks, to ensure that the experiment was ready to play a leading role in the excitement of September 10. Following beampipe bakeout and refill with pure neon, a magnificent effort by the ECAL group and the pt 5 technical crew made it possible to install and commission all 4 ECAL endcap Dees before the end of August. In the shadow of this activity, the barrel and forward pixel trackers and part of the beam monitoring were installed within the vac tank. The pt 5 technical teams then succeeded in safely removing the 20t installation tables and their support blocks from beneath the already installed ...

Furthermore, antioxidant agents are present in extra virgin olive oil and not in olive oil. There is some evidence, based on studies using patients, to support such a supposition. In this paper, we present a case report on the possible health effects of changing from olive oil to extra virgin olive oil. The case report is intended to raise some relevant issues to stimulate a debate and more research in this area.

    Overview Once again, the bulk of this article reviews the intense activity of a recently completed shutdown, which, although quite unforeseeable until a few weeks before it started, proved by its success that our often advertised capability to conduct major maintenance within a two month period is real. Although safely completed, on-time to remarkable precision, the activity was not without incident, and highlighted our dependence on many experienced, specialist teams and their precise choreography. Even after the yoke was safely closed, magnet re-commissioning and beampipe pumpdown showed new and thought-provoking behaviour. The struggle to maintain adequate technical resources will be a pre-occupation over the coming months, in parallel with the start of truly sustained operation, for which various procedures are still being put in place. Planning for future shutdowns must now become a high priority, with many working groups and task forces already in existence to prepare infrastructure improvements and to...

    2016-03-01

    Full Text Available Island states have been shown to outperform continental states on a number of large-scale coordination-related outcomes, such as levels of democracy and institutional quality. The argument developed and tested in this article contends that the same kind of logic may apply to islands’ environmental performance, too. However, the empirical analysis shows mixed results. Among the 105 environmental outcomes that we analyzed, being an island only has a positive impact on 20 of them. For example, island states tend to outcompete continental states with respect to several indicators related to water quality but not in aspects related to biodiversity, protected areas, or environmental regulations. In addition, the causal factors previously suggested to make islands outperform continental states in terms of coordination have weak explanatory power in predicting islands’ environmental performance. We conclude the paper by discussing how these interesting findings can be further explored.

    To characterize potential air pollution issues related to recycling facilities of waste plastics, volatile organic compounds (VOCs) emitted from melted virgin and waste plastics pellets were analyzed. In this study, laboratory experiments were performed to melt virgin and waste plastic pellets under various temperatures (150, 200, and 250 degrees C) and atmospheres (air and nitrogen [N2]). In the study presented here, low-density polyethylene (LDPE), polypropylene (PP), polystyrene (PS) and the recycled waste plastic pellets were used. The VOCs generated from each plastic pellets were collected by Tenax/Carboxen adsorbent tubes and analyzed by thermal desorption-gas chromatography/mass spectrometry (TD-GC/MS). The result showed the higher temperatures generated larger amounts of total VOCs (TVOCs). The VOCs emitted from the virgin plastic pellets likely originated from polymer degradation. Smaller TVOC emissions were observed in N2 atmosphere than in air atmosphere. In particular, larger amounts of the oxygenated compounds, which are generally hazardous and malodorous, were detected in air than in N2. In addition to the compounds originating from polymer degradation, the compounds originating from the plastic additives were also detected from LDPE and PS. Furthermore, various species of VOCs likely originating from contaminant inseparate polyvinyl chloride (PVC), food residues, cleaning agents, degreasers, and so on were detected from the waste plastic. Thus, melting waste plastics, as is conducted in recycling facilities, might generate larger amounts of potentially toxic compounds than producing virgin plastics.
