Drilling the first horizontal well in the Gulf of Mexico; A case history of East Cameron Block 278 Well B-12

DOE Office of Scientific and Technical Information (OSTI.GOV)

Fisher, E.K.; French, M.R.

East Cameron Block 278 Well B-12 was the first horizontal well drilled in the Gulf of Mexico. This gas well, located in the Texaco Inc. operated Eat Cameron 265 field, was drilled and completed in May 1990. The objective formation was a high-permeability, shallow, unconsolidated gas sand located about 1,450 ft below the mudline (BML). The success of this well proved that horizontal wells are viable alternatives to extended-reach development wells from offshore platforms in the Gulf of Mexico. The cost to drill and complete this horizontal well was less than comparable extended-reach development wells drilled in the same field.more » A minimal increase in drilling costs accompanied by considerable savings in completion costs resulted in favorable economics for the project. Drilling a shallow horizontal well in the Gulf of Mexico presented several challenges. This paper discusses prewell planning, formulation of contingency plans, and implementation of a drilling/completion program designed to meet these challenges.« less

USGS Publications Warehouse

Daddow, P.B.

1986-01-01

Groundwater resources in the Hanna and Carbon Basins of Wyoming were assessed in a study from 1974 through 1980 because of the development of coal mining in the area. Data collected from 105 wells during that study, including well-completion records, lithologic logs, and water levels, are presented. The data are from stock wells, coal-test holes completed as observation wells by the U.S. Geological Survey. The data are mostly from mined coal-bearing formations: the Tertiary Hanna Formation and the Tertiary and Cretaceous Ferris Formation. Well-completion data and lithologic logs were collected on-site during drilling of the wells or from U.S. Geological Survey files, company records, Wyoming State Engineer well-permit files, and published reports.

Satellite tree subsea completions permit marginal reserves production offshore East Kalimantan, Indonesia

DOE Office of Scientific and Technical Information (OSTI.GOV)

Bunnell, R.L.; Hawkins, J.G.

1983-05-01

The hydrocarbon-bearing sands in the fields offshore East Kalimantan were deposited in a deltaic environment and are complicated by faulting. This faulting results in small accumulations which cannot be economically exploited by conventional means. Three of these accumulations had been discovered in the Attaka Field in water depths of 160-190 feet. Even though the weather conditions are mild, conventional platforms were ruled out on economic grounds. An alternate method employing subsea completions was found to be economically viable. This subsea system is characterized by its ''off-the-shelf'' configuration and simplicity. To reduce the possibility of required well workovers, the wells aremore » single string, gravel packed completions. This project, then, is an example of a subsea completion system being chosen for marginal reserve development based on economic grounds. Additionally, these are the first subsea completions in Indonesia and yielded much information for use in designing, scheduling, and costing similar installations. The wells were all previously drilled and suspended exploratory wells, and the completion operations were performed from a floating vessel.« less

Ground-water levels in Huron County, Michigan, 2002-03

USGS Publications Warehouse

Weaver, T.L.; Blumer, S.P.; Crowley, S.L.

2008-01-01

In 1990, the U.S. Geological Survey (USGS) completed a study of the hydrogeology of Huron County, Michigan (Sweat, 1991). In 1993, Huron County and the USGS entered into a continuing agreement to collect water-level altitudes (hereafter referred to as water levels) at selected wells throughout Huron County. As part of the agreement, USGS has operated four continuous water-level recorders, installed from 1988 to 1991 on wells in Bingham, Fairhaven, Grant, and Lake Townships (fig. 1) and summarized the data collected in an annual or bi-annual report. The agreement was altered in 2003, and beginning January 1, 2004, only the wells in Fairhaven and Lake Townships will have continuous water-level recorders, while the wells in Grant and Bingham Townships will revert to quarterly measurement status. USGS has also provided training for County or Huron Conservation District personnel to measure the water level, on a quarterly basis, in 23 wells. USGS personnel regularly accompany County or Huron Conservation District personnel to provide a quality assurance/quality control check of all measurements being made. Water-level data collected from the 23 quarterly-measured wells is also summarized in the annual or bi-annual report. In 1998, the USGS also completed a temporal and spatial analysis of the monitoring well network in Huron County (Holtschlag and Sweat, 1998).The altitude of Lake Huron and precipitation are good indicators of general climatic conditions and, therefore, provide an environmental context for groundwater levels in Huron County. Figure 2 shows the mean-monthly water-level altitude of Lake Huron, averaged from measurements made by the U.S. Army Corps of Engineers at sites near Essexville and Harbor Beach, and monthly precipitation measured in Bad Axe (National Oceanic and Atmospheric Administration [NOAA], 2002-04; Danny Costello, NOAA hydrologist, written commun., 2003-04). In March 2003, a new low-water level for the period of this study was measured in Lake Huron (National Oceanic and Atmospheric Administration, 2003; 2004). The net decline in the water level of Lake Huron from January 1, 2002 to December 31, 2003 was about 0.3 ft. Annual precipitation in 2002 was about 0.3 inches above normal, with much of it occurring during summer months. The provisional precipitation total for 2003 is about an inch below normal (NOAA, 2003, 2004; Danny Costello, NOAA hydrologist, written commun., 2003, 2004).Four wells equipped with continuous-data recorders are completed in the glacial, Saginaw, and Marshall aquifers. Water levels in three of the four wells equipped with continuous-data recorders experienced a net decline over the period from January 2002 to December 2003, while the level in well H9r, completed in the Saginaw aquifer in Fairhaven Township adjacent to Saginaw Bay (Lake Huron), rose about 1.3 ft over the same period. Interestingly, the water level in Saginaw Bay declined about 0.3 ft over the same period. A period-ofrecord maximum depth to water was recorded in September 2003 in well H25Ar, completed in the Marshall aquifer in Lake Township. Hydrographs showing altitude of the water surface are presented for each of four wells equipped with continuous-data recorders.Twenty three wells were measured on a quarterly basis in 2002-03. These wells are completed in the Saginaw and Marshall aquifers, and Coldwater confining unit. Although each quarterly measurement only provides a “snapshot” water level, the data adequately define the “generalized” water-level trend in the aquifer near the well. The water level in one quarterly-measured well completed in the Saginaw aquifer near Saginaw Bay, had a net rise for the period from January 2002 to December 2003, while levels in the other 22 quarterly-measured wells declined about 0.5 to 2.0 ft during the same period. A period-of-record minimum depth to water (high) was measured in 2002 in two quarterly-measured wells completed in the Saginaw aquifer, although the level in one of those wells had a net decline over the period from January 2002 through December 2003. Conversely, period-of-record maximum depths to water (low) were measured in 2002 in one well completed in the Saginaw aquifer and two wells completed in the Marshall aquifer; and in 2003, in 6 of 16 wells completed in the Marshall aquifer. Near period-ofrecord maximum depths to water were measured in 2003 in two additional wells completed in the Marshall aquifer. No period-of-record minimum or maximum depths to water were measured in 2002-03 in wells completed in the Coldwater confining unit. Hydrographs showing water levels measured in each well are presented for the 23 wells measured on a quarterly basis.Water-level trends measured in 2002-03 in other wells in Lower Michigan have similarities to those measured in Huron County wells. Several external factors appear to influence water-level trends including proximity to nearby production wells, amount and timing of precipitation events, evapotranspiration and type of prevalent ground cover, proximity of aquifer to the surface, and hydraulic characteristics of overlying geologic materials.

Interpretation of geologic and hydrologic data from the Ray-1 Well, City of Gallup, McKinley County, New Mexico

USGS Publications Warehouse

Hiss, William L.; Marshall, Jane G.

1975-01-01

The Ray-1 well was to be the third production well completed in the city of Gallup Yah-ta-hey well field located about 7 miles (11 km) north of the city. The first string of casing collapsed during completion, however, and the well was abandoned before it could be tested. The lithology of the Upper Cretaceous Dalton Sandstone and Dilco Coal Members of the Crevasse Canyon Formation and the Gallup Sandstone was interpreted from geophysical logs and examination of the drill cuttings. These units appear to be similar to correlative strata encountered in the first two wells. A yield of approximately 700 gallons per minute (44 l/s), similar to the other wells in the Yah-ta-hey well field, is anticipated from the same aquifers when the Ray-1 replacement well is completed.

How PEMEX engineered a deep well completion

DOE Office of Scientific and Technical Information (OSTI.GOV)

Antimo A., J.C.

1971-09-01

Completion and testing of Petroleos Mexicano's W. Reynosa Well No. 1 in the NE. Frontier District south of the Texas border required engineering innovation to combat the 375/sup 0/F temperatures and pressures near 18,000 psi. Drilled to nearly 18,000 ft, the well was completed and tested below 17,000 ft. Completion plans were designed to determine the economic importance of the reservoir and to provide information and experience in planning future completions to 20,000 ft and deeper. Interval selection was based in part on data acquired during drilling, including lithology, geologic age, rock characteristics, and sensitivity to damage caused by drillingmore » fluids. A set of logs was obtained and evaluated by computer in correlation with mud-log and pressure data. The logs also were correlated with logs from other wells in the area. Pressure gradients in the Reynosa field indicated the possibility of pressures on the order of 10,000 psi, and required the use of specially designed valves rated to 20,000 psi, in conjunction with a casinghead that would permit drilling to the projected depth. A choke manifold consisted of an interchangeable, manually operated positive choke and a set of automatic adjustable chokes. Well conditioning, including cementing, perforating, and well plugging are described.« less

Completion Design Considerations for a Horizontal Enhanced Geothermal System

DOE Office of Scientific and Technical Information (OSTI.GOV)

Olson, Jeffrey; Eustes, Alfred; Fleckenstein, William

2015-09-02

The petroleum industry has had considerable success in recent decades in developing unconventional shale plays using horizontal drilling and multi-zonal isolation and stimulation techniques to fracture tight formations to enable the commercial production of oil and gas. Similar well completions could be used in Enhanced Geothermal Systems (EGS) to create multiple fractures from horizontal wells. This study assesses whether well completion techniques used in the unconventional shale industry to create multi-stage fractures can be applied to an enhanced geothermal system, with a focus on the completion of the EGS injection well. This study assumes an Enhanced Geothermal System (EGS) consistingmore » of a central horizontal injection well flanked on each side by horizontal production wells, connected to the injection well by multiple fractures. The focus is on the design and completion of the horizontal well. For the purpose of developing design criteria, a reservoir temperature of 200 degrees C (392 degrees F) and an injection well flow rate of 87,000 barrels per day (160 kg/s), corresponding to production well flow rates of 43,500 barrels per day (80 kg/s) is assumed. The analysis found that 9-5/8 inches 53.5 pounds per foot (ppf) P110 casing string with premium connections meets all design criteria for the horizontal section of injection well. A P110 grade is fairly common and is often used in horizontal sections of shale development wells in petroleum operations. Next, several zonal isolation systems commonly used in the shale gas industry were evaluated. Three techniques were evaluated -- a 'plug and perf' design, a 'sand and perf' design, and a 'packer and port' design. A plug and perf system utilizes a cemented casing throughout the length of the injector wellbore. The sand and perf system is identical to the plug and perf system, but replaces packers with sand placed in the casing after stimulation to screen out the stimulated perforated zones and provide zonal isolation. The packer and port completion approach utilizes an open horizontal hole that zonally isolates areas through the use of external packers and a liner. A review of technologies used in these systems was performed to determine if commercially available equipment from the petroleum industry could be used at the temperatures, pressures, and sizes encountered in geothermal settings. The study found no major technical barriers to employing shale gas multi-zonal completion techniques in a horizontal well in a geothermal setting for EGS development. For all techniques considered, temperature limitations of equipment are a concern. Commercially available equipment designed to operate at the high temperatures encountered in geothermal systems are available, but is generally unproven for geothermal applications. Based on the study, further evaluation of adapting oil and gas completion techniques to EGS is warranted.« less

In 1988, the Geological Survey (USGS) began study to examine the hydrogeologic framework, ground-water-flow systems, water chemistry, and withdrawal response of aquifers in glacial deposits and carbonate rock in the Midwestern Basins and Arches Region in western Ohio and eastern Indiana. As part of this study, data from pumped-well tests and instantaneous-rechange tests (slug tests) of wells completed in the glacial-deposit and carbonate-rock aquifers were compiled from reports and information on file with State agencies, environmental consulting firms, drilling firms, municipalities, universities, and the USGS. The data, from 73 counties in Ohio and Indiana, were entered into a computerized data base in a spreadsheet format and subsequently into a geographic information system (GIS). Aquifer-characteristics data from this compilation include the results of 105 pumped-well tests and 39 slug tests in wells completed in glacial deposits, 174 pumped-well tests in wells completed in the carbonate-rock aquifer, and 4 slug tests in wells completed in limestones and shales of Ordovician age. Transmissivities from the pumped-well tests in wells completed in glacial till and glacial-deposit aquifers (sands and gravels) range from 1.54 to 69,700 feet squared per day. Storage coefficients or specific yields range from 0.00002 to 0.38 at these wells. Horizontal-hydraulic conductivities from the slug tests in wells completed in glacial-deposit aquifers range from 0.33 to 1,000 feet per day. Transmissivities from the pumped-well tests in wells completed in the carbonate-rock aquifer range from 70 to 52,000 feet squared per day. Storage coefficient or specific yields at these wells range from 0.00001 to 0.05. Horizontal hydraulic conductivities from the slug tests in wells completed in limestones and shales of Ordovician age range from 0.0016 to 12 feet per day. These data are summarized in tables and figures within this report. The collection and compilation of selected aquifer-characteristic data for the glacial-deposit and carbonate-rock aquifers within the Midwestern Basin and Arches Region of Shaver (1985) are an essential part of the Midwestern Basins and Arches Regional Aquifer-Systems Analysis (Midwestern Basins and Arches RASA) project of the U.S. Geological Survey (USGS). Specifically, the data are needed to help describe ground-water flow in the regional aquifer system, which isone of the objectives of the Midwestern Basins and Arches RASA project (Bugliosi, 1990). To meet this objective, the Midwestern Basins and Arches RASA began subprojects in the Ohio and Indiana offices of the USGS to collect and compile available aquifer-characteristics data from aquifer tests of the glacial-deposit and carbonate-rock aquifers. The data were not reanalyzed to verify accuracy because of time constraints and insufficient data in many cases.

Method for producing viscous hydrocarbons

DOEpatents

Poston, Robert S.

1982-01-01

A method for recovering viscous hydrocarbons and synthetic fuels from a subterranean formation by drilling a well bore through the formation and completing the well by cementing a casing means in the upper part of the pay zone. The well is completed as an open hole completion and a superheated thermal vapor stream comprised of steam and combustion gases is injected into the lower part of the pay zone. The combustion gases migrate to the top of the pay zone and form a gas cap which provides formation pressure to produce the viscous hydrocarbons and synthetic fuels.

Approximation methods for the stability analysis of complete synchronization on duplex networks

NASA Astrophysics Data System (ADS)

Han, Wenchen; Yang, Junzhong

2018-01-01

Recently, the synchronization on multi-layer networks has drawn a lot of attention. In this work, we study the stability of the complete synchronization on duplex networks. We investigate effects of coupling function on the complete synchronization on duplex networks. We propose two approximation methods to deal with the stability of the complete synchronization on duplex networks. In the first method, we introduce a modified master stability function and, in the second method, we only take into consideration the contributions of a few most unstable transverse modes to the stability of the complete synchronization. We find that both methods work well for predicting the stability of the complete synchronization for small networks. For large networks, the second method still works pretty well.

1989-09-01

Prior to the 1977 discovery of the Cedar Hill Basal Fruitland pool (the first officially designated coal-bed methane field in the western US) 28.5 bcf of gas had been produced from Fruitland Formation coal seams in the Ignacio Blanco Fruitland-Pictured Cliffs field, Northern San Juan basin, Colorado. The discovery well for the field, Southern Ute D-1, was drilled and completed in 1951 on the Ignacio anticline, La Plata County, Colorado. Initial completion was attempted in the Pictured Cliffs Sandstone. The well was plugged back after making water from the Pictured Cliffs and was completed in the lower coal-bearing section ofmore » the Fruitland Formation. The well produced 487,333 mcf of gas in nine years and was abandoned in 1959 due to water encroachment. Additionally, 52 similarly completed Ignacio anticline Fruitland wells were abandoned by the early 1970s due to the nemesis of If it's starting to kick water, you're through. Under today's coal-bed methane technology and economics, Amoco has twinned 12 of the abandoned wells, drilled five additional wells, and is successfully dewatering and producing adsorbed methane from previously depleted coal sections of the Ignacio structure. Field-wide drilling activity in 1988 exceeded all previous annual levels, with coal-seam degasification projects leading the resurgence. Drilling and completion forecasts for 1989 surpass 1988 levels by 50%.« less

Improved recovery demonstration for Williston Basin carbonates. Final report

DOE Office of Scientific and Technical Information (OSTI.GOV)

Sippel, M.A.

The purpose of this project was to demonstrate targeted infill and extension drilling opportunities, better determinations of oil-in-place, and methods for improved completion efficiency. The investigations and demonstrations were focussed on Red River and Ratcliffe reservoirs in the Williston Basin within portions of Montana, North Dakota and South Dakota. Both of these formations have been successfully explored with conventional 2-dimensional (2D) seismic. Improved reservoir characterization utilizing 3-dimensional (3D) seismic was investigated for identification of structural and stratigraphic reservoir compartments. These seismic characterizations were integrated with geological and engineering studies. The project tested lateral completion techniques, including high-pressure jetting lance technologymore » and short-radius lateral drilling to enhance completion efficiency. Lateral completions should improve economics for both primary and secondary oil where low permeability is a problem and higher-density drilling of vertical infill wells is limited by drilling cost. New vertical wells were drilled to test bypassed oil in ares that were identified by 3D seismic. These new wells are expected to recover as much or greater oil than was produced by nearby old wells. The project tested water injection through vertical and horizontal wells in reservoirs where application of waterflooding has been limited. A horizontal well was drilled for testing water injection. Injection rates were tested at three times that of a vertical well. This demonstration well shows that water injection with horizontal completions can improve injection rates for economic waterflooding. This report is divided into two sections, part 1 covers the Red River and part 2 covers the Ratcliffe. Each part summarizes integrated reservoir characterizations and outlines methods for targeting by-passed oil reserves in the respective formation and locality.« less

Hydrologic Tests at Characterization Wells R-9i, R-13, R-19, R-22, and R-31, Revision 1

DOE Office of Scientific and Technical Information (OSTI.GOV)

S.G.McLin; W.J. Stone

2004-06-01

Hydrologic information is essential for environmental efforts at Los Alamos National Laboratory. Testing at new characterization wells being drilled to the regional aquifer (''R wells'') to improve the conceptual hydrogeologic model of the Pajarito Plateau is providing such information. Field tests were conducted on various zones of saturation penetrated by the R wells to collect data needed for determining hydraulic properties. This document provides details of the design and execution of testing as well as an analysis of data for five new wells: R-9i, R-13, R-19, R-22, and R-31. One well (R-13) was evaluated by a pumping test and themore » rest (R-9i, R-19, R-22, and R-31) were evaluated by injection tests. Characterization well R-9i is located in Los Alamos Canyon approximately 0.3 mi west of the Route 4/Route 502 intersection. It was completed at a depth of 322 ft below ground surface (bgs) in March 2000. This well was constructed with two screens positioned below the regional water table. Both screens were tested. Screen 1 is completed at about 189-200 ft bgs in fractured basalt, and screen 2 is completed at about 270-280 ft bgs in massive basalt. Specific capacity analysis of the screen 1 data suggests that the fractured basalt has a transmissivity (T) of 589 ft{sup 2}/day and corresponds to a hydraulic conductivity (K) of 7.1 ft/day based on a saturated thickness of 83 ft. The injection test data from the massive basalt near screen 2 were analyzed by the Bouwer-Rice slug test methodology and suggest that K is 0.11 ft/day, corresponding to a T of about 2.8 ft{sup 2}/day based on a saturated thickness of 25 ft. Characterization well R-13 is located in Mortandad Canyon just west of the eastern Laboratory boundary. It was completed at a depth of 1029 ft bgs in February 2002. This well was constructed with one 60-ft long screen positioned about 125 ft below the regional water table. This screen is completed at about 958-1019 ft bgs and straddles the geologic contact between the Puye fanglomerate and unassigned pumiceous units. The specific capacity analysis of a 12 minute pumping test indicates that the Puye fanglomerates near the R-13 screen have a T of 5269 ft{sup 2}/day and correspond to a hydraulic conductivity (K) of 17.6 ft/day based on a saturated thickness of 300 ft. Characterization well R-19 is located east of firing site IJ in Technical Area (TA) 36 on the mesa between Three-mile and Potrillo Canyons. It was completed at a depth of 1885 ft bgs in April 2000. This well was constructed with two screens positioned above the regional water table and five screens positioned below the regional water table. Only the bottom two screens were tested. Screen 6 is completed at about 1727-1734 ft bgs in Puye fanglomerate, and screen 7 is completed at about 1832-1849 ft bgs in Puye fanglomerate. Specific capacity analysis of the screen 6 data suggests that T is about 6923 ft{sup 2}/day and corresponds to a K of 18.6 ft/day based on a saturated thickness of 373 ft. Specific capacity analysis of the screen 7 data suggests that T is about 8179 ft{sup 2}/day and corresponds to a K of 22.0 ft/day based on a saturated thickness of 373 ft. Characterization well R-22 is located on Mesita del Buey between Canada del Buey and Pajarito Canyons immediately east of Material Disposal Area (MDA) G in TA-54. It was completed at a depth of 1489 ft bgs in October 2000. This well was constructed with five screens positioned at or below the regional water table; however, only screens 2-5 were tested. Screen 1 is completed at the regional water table at about 872-914 ft bgs in Cerros del Rio basalt. Screen 2 is completed at about 947-989 ft bgs in Cerros del Rio basalt. Screen 3 is completed at about 1272-1279 ft bgs in Puye fanglomerate. Screen 4 is completed at about 1378-1452 ft bgs in older basalt. Screen 5 is completed at about 1447-1452 ft bgs in older fanglomerate. Bouwer-Rice analyses of the injection-test recovery data suggest K values of 0.04, 0.32, 0.54, and 0.27 ft/day for screens 2, 3, 4, and 5, respectively. These values correspond to T values of 2.8, 15.8, 26.5, and 11.6 ft{sup 2}/day, respectively, for screens 2, 3, 4, and 5. These analyses are based on saturated thicknesses of 69.5 ft, 49.4 ft, 49.0 ft, and 43.0 ft, respectively. Characterization well R-31 is located at TA-39 in the north fork of lower Ancho Canyon. It was completed at a depth of 1103 ft bgs in April 2000. This well was constructed with one screen positioned above the regional water table, and four screens position at or below the regional water table.« less

Simulation of ground-water flow in glaciofluvial aquifers in the Grand Rapids area, Minnesota

USGS Publications Warehouse

Jones, Perry M.

2004-01-01

A calibrated steady-state, finite-difference, ground-waterflow model was constructed to simulate ground-water flow in three glaciofluvial aquifers, defined in this report as the upper, middle, and lower aquifers, in an area of about 114 mi2 surrounding the city of Grand Rapids in north-central Minnesota. The calibrated model will be used by Minnesota Department of Health and communities in the Grand Rapids area in the development of wellhead protection plans for their water supplies. The model was calibrated through comparison of simulated ground-water levels to measured static water levels in 351 wells, and comparison of simulated base-flow rates to estimated base-flow rates for reaches of the Mississippi and Prairie Rivers. Model statistics indicate that the model tends to overestimate ground-water levels. The root mean square errors ranged from +12.83 ft in wells completed in the upper aquifer to +19.10 ft in wells completed in the middle aquifer. Mean absolute differences between simulated and measured water levels ranged from +4.43 ft for wells completed in the upper aquifer to +9.25 ft for wells completed in the middle aquifer. Mean algebraic differences ranged from +9.35 ft for wells completed in the upper aquifer to +14.44 ft for wells completed in the middle aquifer, with the positive differences indicating that the simulated water levels were higher than the measured water levels. Percentage errors between simulated and estimated base-flow rates for the three monitored reaches all were less than 10 percent, indicating good agreement. Simulated ground-water levels were most sensitive to changes in general-head boundary conductance, indicating that this characteristic is the predominant model input variable controlling steady-state water-level conditions. Simulated groundwater flow to stream reaches was most sensitive to changes in horizontal hydraulic conductivity, indicating that this characteristic is the predominant model input variable controlling steady-state flow conditions.

Case studies from Oman for coiled tubing deployed completion techniques

DOE Office of Scientific and Technical Information (OSTI.GOV)

Taylor, R.W.; Conrad, B.

1996-09-01

Although the use of ultra-large coiled tubing to complete wells is relatively new, it is gaining widespread industry application. This paper will detail the equipment necessary to perform an operation of this type and will present information from several case studies in Oman in which an operator has successfully deployed completion equipment on 3-1/2-inch-OD coiled tubing. In addition to a discussion of the equipment required to perform the necessary operations, the trial parameters that were established by this operator will be given. The information presented has been selected to allow an initial evaluation to be made of coiled tubing completionsmore » in general and will help to determine whether this method can prove to be less expensive than traditional rig-based completions. The topics presented have been chosen to provide the reader with a thorough understanding of the techniques and preparation needed to execute a coiled tubing completion. The summary of experiences will conclude that this innovative completion technique can be a viable method for completing wells. Although long-term advantages regarding production and well maintenance cannot yet be determined, the operator`s experiences to date have confirmed his initial belief that use of coiled tubing in ultra-large continuous-pipe applications can be cost effective.« less

Increased Oil Production and Reserves from Improved Completion Techniques in the Bluebell Field, Uinta Basin, Utah

DOE Office of Scientific and Technical Information (OSTI.GOV)

Deo, M.D.; Morgan, C.D.

1999-04-28

The objective of the project is to increase oil production and reserves by the use of improved reservoir characterization and completion techniques in the Uinta Basin, Utah. To accomplish this objective, a two-year geologic and engineering characterization of the Bluebell field was conducted. The study evaluated surface and subsurface data, currently used completion techniques, and common production problems. It was determined that advanced case- and open-hole logs could be effective in determining productive beds and that stage-interval (about 500 ft [150 m] per stage) and bed-scale isolation completion techniques could result in improved well performance. In the first demonstration wellmore » (Michelle Ute well discussed in the previous technical report), dipole shear anisotropy (anisotropy) and dual-burst thermal decay time (TDT) logs were run before and isotope tracer log was run after the treatment. The logs were very helpful in characterizing the remaining hydrocarbon potential in the well. But, mechanical failure resulted in a poor recompletion and did not result in a significant improvement in the oil production from the well.« less

Reservoir engineering applications for development and exploitation of geothermal fields in the Philippines

DOE Office of Scientific and Technical Information (OSTI.GOV)

Vasquez, N.C.; Sarmiento, Z.F.

1986-07-01

After a geothermal well is completed, several tests and downhole measurements are conducted to help evaluate the subsurface fluid and reservoir properties intersected. From these tests, a conceptual model of the well can be developed by integrating data from the various parts of the field. This paper presents the completion techniques applied in geothermal wells, as well as the role of reservoir engineering science in delineating a field for development. Monitoring techniques and other reservoir engineering aspects of a field under exploitation are also discussed, with examples from the Philippines.

Lithologic, natural-gamma, grain-size, and well-construction data for Wright-Patterson Air Force Base, Ohio

USGS Publications Warehouse

Dumouchelle, D.H.; De Roche, Jeffrey T.

1991-01-01

Wright-Patterson Air Force Base, in southwestern Ohio, overlies a buried-valley aquifer. The U.S. Geological Survey installed 35 observation wells at 13 sites on the base from fall 1988 through spring 1990. Fourteen of the wells were completed in bedrock; the remaining wells were completed in unconsolidated sediments. Split-spoon and bedrock cores were collected from all of the bedrock wells. Shelby-tube samples were collected from four wells. The wells were drilled by either the cable-tool or rotary method. Data presented in this report include lithologic and natural-gamma logs, and, for selected sediment samples, grain-size distributions of permeability. Final well-construction details, such as the total depth of well, screened interval, and grouting details, also are presented.

The chicken or the egg? Systematic investigation of the effect of order of administration of Memory Questionnaires and Well-being Scales.

PubMed

Philippe, Frederick L; Bouizegarene, Nabil; Guilbault, Valérie; Rajotte, Guillaume; Houle, Iliane

2015-01-01

Narrative research claims that episodic/autobiographical memory characteristics and themes represent stable individual differences that relate to well-being. However, the effects of the order of administration of memory descriptions and well-being scales have never been investigated. Of importance, social cognitive research has shown that trivial contextual factors, such as completing a self-report measure, can influence the type of memories recollected afterwards and that memory recollection can transiently affect subsequent self-report ratings--both of which underscore that transient contextual effects, rather than stable individual differences in memory could be responsible for the correlation between memory characteristics and well-being. The present study examined if the order in which (positive or negative) memory and well-being scales are completed affects the characteristics and themes of the memory described, the scores of well-being reported and the relationship between the two. The results revealed some effects of order of administration when memories were described before completing well-being scales, but only on a situational measure of well-being, not on a trait measure. In sum, we recommend assessing memory-related material at the end of questionnaires to avoid potential mood-priming effects.

There is a need to develop a tool that will measure data completeness of patient records using sophisticated statistical metrics. Patient data integrity is important in providing timely and appropriate care. Completeness is an important step, with an emphasis on understanding the complex relationships between data fields and their relative importance in delivering care. This tool will not only help understand where data problems are but also help uncover the underlying issues behind them. Develop a tool that can be used alongside a variety of health care database software packages to determine the completeness of individual patient records as well as aggregate patient records across health care centers and subpopulations. The methodology of this project is encapsulated within the Data Completeness Analysis Package (DCAP) tool, with the major components including concept mapping, CSV parsing, and statistical analysis. The results from testing DCAP with Healthcare Cost and Utilization Project (HCUP) State Inpatient Database (SID) data show that this tool is successful in identifying relative data completeness at the patient, subpopulation, and database levels. These results also solidify a need for further analysis and call for hypothesis driven research to find underlying causes for data incompleteness. DCAP examines patient records and generates statistics that can be used to determine the completeness of individual patient data as well as the general thoroughness of record keeping in a medical database. DCAP uses a component that is customized to the settings of the software package used for storing patient data as well as a Comma Separated Values (CSV) file parser to determine the appropriate measurements. DCAP itself is assessed through a proof of concept exercise using hypothetical data as well as available HCUP SID patient data.

Comments on some of the drilling and completion problems in Cerro Prieto geothermal wells

DOE Office of Scientific and Technical Information (OSTI.GOV)

Dominguez A, B.; Sanchez G, G.

From 1960 to the present, 85 wells with a total drilling length exceeding 160,000 m have been constructed at Cerro Prieto, a modest figure compared to an oil field. This activity took place in five stages, each characterized by changes and modifications required by various drilling and well-completion problems. Initially, the technical procedures followed were similar to those used in the oil industry. However, several problems emerged as a result of the relatively high temperatures found in the geothermal reservoir. The various problems that have been encountered can be considered to be related to drilling fluids, cements and cementing operations,more » lithology, geothermal fluid characteristics, and casings and their accessories. As the importance of high temperatures and the characteristics of the geothermal reservoir fluids were better understood, the criteria were modified to optimize well-completion operations, and satisfactory results have been achieved to date.« less

Benzene contamination at a metal plating facility

NASA Astrophysics Data System (ADS)

Memon, B. A.; Burston, M. R.

2005-08-01

A metal plating facility in central Kentucky was required to complete a RCRA Facility Investigation to address a number of Solid Waste Management Units at the site. Twenty monitoring wells were installed at the facility. Ground water from the wells was sampled for total and dissolved metals, polychlorinated biphenyls, acid extractable compounds, base neutral compounds, and volatile organic compounds. Unexpectedly, relatively large concentrations of benzene, up to 120 μg/l, were detected in samples from some of the wells, including wells that should have been hydraulically upgradient from the facility. As a result of the detection of benzene, the facility completed an investigation to identify the source. A nearby facility had completed a gasoline underground storage tank (UST) closure at about the time of the installation of the 20 wells. Reportedly the UST had small holes when removed. Three potential pathways of migration (a ditch, sanitary sewer, and a sink hole) from the nearby facility to the metal-plating facility and residual soils with very large concentrations of benzene, toluene, ethylbenzene, and xylenes have been identified.

In February and March 2000, the U.S. Geological Survey Western Regional Research Drilling Operation constructed replacement monitoring wells MW 3–2, MW 6–2, MW 7–2, and MW 11–2 as part of a regional ground-water monitor- ing network for the Mountain Home Air Force Base, Elmore County, Idaho. Total well depths ranged from 435.5 to 456.5 feet, and initial depth-to-water measurements ranged from about 350 to 375 feet below land surface. After completion, wells were pumped and onsite measurements were made of water temperature, specific conductance, pH, and dissolved oxygen. At each well, natural gamma, spontaneous potential, resistivity, caliper, and temperature logs were obtained from instruments placed in open boreholes. A three- dimensional borehole flow analysis was completed for MW 3–2 and MW 11–2, and a video log was obtained for MW 11–2 to annotate lithology and note wet zones in the borehole above saturated rock.

The Bluebell field is productive from the Tertiary lower Green River and Wasatch Formations of the Uinta Basin, Utah. The productive interval consists of thousands of feet of interbedded fractured clastic and carbonate beds deposited in a fluvial-dominated lacustrine environment. Wells in the Bluebell field are typically completed by perforating 40 or more beds over 1,000 to 3,000 vertical feet (300-900 m), then stimulating the entire interval. This completion technique is believed to leave many potentially productive beds damaged and/or untreated, while allowing water-bearing and low-pressure (thief) zones to communicate with the wellbore. Geologic and engineering characterization has been usedmore » to define improved completion techniques. A two-year characterization study involved detailed examination of outcrop, core, well logs, surface and subsurface fractures, produced oil-field waters, engineering parameters of the two demonstration wells, and analysis of past completion techniques and effectiveness. The characterization study resulted in recommendations for improved completion techniques and a field-demonstration program to test those techniques. The results of the characterization study and the proposed demonstration program are discussed in the second annual technical progress report. The operator of the wells was unable to begin the field demonstration this project year (October 1, 1995 to September 20, 1996). Correlation and thickness mapping of individual beds in the Wasatch Formation was completed and resulted in a. series of maps of each of the individual beds. These data were used in constructing the reservoir models. Non-fractured and fractured geostatistical models and reservoir simulations were generated for a 20-square-mile (51.8-km{sup 2}) portion of the Bluebell field. The modeling provides insights into the effects of fracture porosity and permeability in the Green River and Wasatch reservoirs.« less

Analysis of water levels in the Frenchman Flat area, Nevada Test Site

USGS Publications Warehouse

Bright, D.J.; Watkins, S.A.; Lisle, B.A.

2001-01-01

Analysis of water levels in 21 wells in the Frenchman Flat area, Nevada Test Site, provides information on the accuracy of hydraulic-head calculations, temporal water-level trends, and potential causes of water-level fluctuations. Accurate hydraulic heads are particularly important in Frenchman Flat where the hydraulic gradients are relatively flat (less than 1 foot per mile) in the alluvial aquifer. Temporal water-level trends with magnitudes near or exceeding the regional hydraulic gradient may have a substantial effect on ground-water flow directions. Water-level measurements can be adjusted for the effects of barometric pressure, formation water density (from water-temperature measurements), borehole deviation, and land-surface altitude in selected wells in the Frenchman Flat area. Water levels in one well were adjusted for the effect of density; this adjustment was significantly greater (about 17 feet) than the adjustment of water levels for barometric pressure, borehole deviation, or land-surface altitude (less than about 4 feet). Water-level measurements from five wells exhibited trends that were statistically and hydrologically significant. Statistically significant water-level trends were observed for three wells completed in the alluvial aquifer (WW-5a, UE-5n, and PW-3), for one well completed in the carbonate aquifer (SM-23), and for one well completed in the quartzite confining unit (Army-6a). Potential causes of water-level fluctuations in wells in the Frenchman Flat area include changes in atmospheric conditions (precipitation and barometric pressure), Earth tides, seismic activity, past underground nuclear testing, and nearby pumping. Periodic water-level measurements in some wells completed in the carbonate aquifer indicate cyclic-type water-level fluctuations that generally correlate with longer term changes (more than 5 years) in precipitation. Ground-water pumping fromthe alluvial aquifer at well WW-5c and pumping and discharge from well RNM-2s appear to cause water-level fluctuations in nearby observation wells. The remaining known sources of water-level fluctuations do not appear to substantially affect water-level changes (seismic activity and underground nuclear testing) or do not affect changes over a period of more than 1 year (barometric pressure and Earth tides) in wells in the Frenchman Flat area.

Wellbore Completion Systems Containment Breach Solution Experiments at a Large Scale Underground Research Laboratory : Sealant placement & scale-up from Lab to Field

NASA Astrophysics Data System (ADS)

Goodman, H.

2017-12-01

This investigation seeks to develop sealant technology that can restore containment to completed wells that suffer CO2 gas leakages currently untreatable using conventional technologies. Experimentation is performed at the Mont Terri Underground Research Laboratory (MT-URL) located in NW Switzerland. The laboratory affords investigators an intermediate-scale test site that bridges the gap between the laboratory bench and full field-scale conditions. Project focus is the development of CO2 leakage remediation capability using sealant technology. The experimental concept includes design and installation of a field scale completion package designed to mimic well systems heating-cooling conditions that may result in the development of micro-annuli detachments between the casing-cement-formation boundaries (Figure 1). Of particular interest is to test novel sealants that can be injected in to relatively narrow micro-annuli flow-paths of less than 120 microns aperture. Per a special report on CO2 storage submitted to the IPCC[1], active injection wells, along with inactive wells that have been abandoned, are identified as one of the most probable sources of leakage pathways for CO2 escape to the surface. Origins of pressure leakage common to injection well and completions architecture often occur due to tensile cracking from temperature cycles, micro-annulus by casing contraction (differential casing to cement sheath movement) and cement sheath channel development. This discussion summarizes the experiment capability and sealant testing results. The experiment concludes with overcoring of the entire mock-completion test site to assess sealant performance in 2018.

2016-01-01

Objective A randomized control trial with 722 eligible clients from a health department in the State of Florida was conducted to identify a simple, effective meta-intervention to increase completion of an HIV-prevention counseling program. Method The overall design involved two factors representing an empowering and instrumental message, as well as an additional factor indicating presence or absence of expectations about the counseling. Completion of the three-session counseling was determined by recording attendance. Results A logistic regression analysis with the three factors of empowering message, instrumental message, and presence of mediator measures, as well as all interactions, revealed significant interactions between instrumental and empowering messages and between instrumental messages and presence of mediator measures. Results indicated that (a) the instrumental message alone produced most completion than any other message, and (b) when mediators were not measured, including the instrumental message led to greater completion. Conclusions The overall gains in completion as a result of the instrumental message were 16%, implying success in the intended facilitation of counseling completion. The measures of mediators did not detect any experimental effects, probably because the effects were happening without much conscious awareness. PMID:27786499

1987-11-01

This report documents the progress of four Hanford Site ground-water monitoring projects for the period from July 1 to September 310, 1987. The four disposal facilities are the 300 Area Process Trenches, 183-H Solar Evaporation Basins, 200 Area Low-Level Burial Grounds, and Nonradioactive Dangerous Waste (NRDW) Landfill. This report is the fifth in a series of periodic status reports. During this reporting period, field activities consisted of completing repairs on five monitoring wells originally present around the 183-H Basins and completing construction of 25 monitoring wells around the 200 Area Burial Grounds. The 14 wells in the 200 East Areamore » were completed by Kaiser Engineers Hanford (KEH) and the 11 wells in the 200 West Area were compelted by ONWEGO Well Drilling. The NRDW Landfill interim characterization report was submitted to the WDOE and the USEPA in August 1987. Analytical results for the 300 Area, 183-H, and the NRDW Landfill indicate no deviations from previously established trends. Results from the NRDW Land-fill indiate that the facility has no effect on the ground-water quality beneath the facility, except for the detection of coliform bacteria. A possible source of this contamination is the solid-waste lanfill (SWL) adjacent to the NRDW Landfill. Ground-water monitoring data for the NRDW and SWL will be evaluated together in the future. Aquifer testing was completed in the 25 new wells surrounding the 200 Area buiral grounds. 13 refs., 19 refs., 13 tabs.« less

Delineation of water sources for public-supply wells in three fractured-bedrock aquifer systems in Massachusetts

USGS Publications Warehouse

Lyford, Forest P.; Carlson, Carl S.; Hansen, Bruce P.

2003-01-01

Fractured-bedrock aquifer systems in West Newbury, Maynard, and Paxton, Massachusetts, were studied to advance methods of data collection and analysis for delineating contributing areas to public-supply wells completed in fractured rock and for determining the effects of pumping on streams and wetlands. Contributing areas, as defined for this study, include all areas through which ground water flows from recharge areas to wells. In West Newbury, exploratory public-supply wells at two locations were completed in phyllite of the Eliot Formation. Aquifer testing indicated that subhorizontal and steeply dipping fractures that parallel two sets of foliation form elongated transmissive zones in the bedrock aquifer near the two well locations and also form a vertical hydraulic connection to surficial materials consisting of till at one location and marine clay at the other location. Recharge to bedrock is largely through a thin veneer of till over bedrock, but leakage through thick drumlin tills also recharges bedrock. Simulated contributing areas for the three supply wells pumped at a combined rate of 251 gallons per minute encompass about 1.3 square miles and extend to ground-water divides within most of a subbasin of the Artichoke River. Pumping likely would reduce streamflow in the Artichoke River subbasin by approximately the pumping rate. Pumping is likely to affect wetland areas underlain by till near the wells because of the vertical hydraulic connection to surficial materials. In Maynard, three exploratory public-supply wells were completed in coarse-grained schist of the Nashoba Formation. Aquifer testing indicated that a dense network of fractures in bedrock forms a laterally extensive transmissive zone in bedrock that is well connected vertically to surficial materials consisting of sandy till, lacustrine silts, sand and gravel, and wetland deposits. The simulated contributing area for the three supply wells pumped at a combined rate of 780 gallons per minute encompasses about 1.8 square miles of the Fort Pond Brook drainage area. Pumping likely would reduce streamflow in Fort Pond Brook by about the same amount as the pumping rate, and wetland-water levels within a 2,000-foot radius from the wells are likely to be lowered below the land surface by pumping. In Paxton, three existing supply wells are completed in granofels and schist of the Paxton and Littleton Formations. Aquifer testing demonstrated that a shallow bedrock well completed to a depth of 150 feet is closely connected hydraulically to overlying till. Two deep wells, however, receive much of their water from fractures at depths below 500 feet. Ground-water flow in bedrock appears to be mostly through parting fractures along a foliation set that dips gently (10 degrees) eastward. These parting fractures at depth are poorly connected vertically to shallow bedrock

Efficient Tensor Completion for Color Image and Video Recovery: Low-Rank Tensor Train.

PubMed

Bengua, Johann A; Phien, Ho N; Tuan, Hoang Duong; Do, Minh N

2017-05-01

This paper proposes a novel approach to tensor completion, which recovers missing entries of data represented by tensors. The approach is based on the tensor train (TT) rank, which is able to capture hidden information from tensors thanks to its definition from a well-balanced matricization scheme. Accordingly, new optimization formulations for tensor completion are proposed as well as two new algorithms for their solution. The first one called simple low-rank tensor completion via TT (SiLRTC-TT) is intimately related to minimizing a nuclear norm based on TT rank. The second one is from a multilinear matrix factorization model to approximate the TT rank of a tensor, and is called tensor completion by parallel matrix factorization via TT (TMac-TT). A tensor augmentation scheme of transforming a low-order tensor to higher orders is also proposed to enhance the effectiveness of SiLRTC-TT and TMac-TT. Simulation results for color image and video recovery show the clear advantage of our method over all other methods.

The development of an engineering tool (in the form of a computer model) for solving design and analysis problems related with oil and gas well production operations is discussed. The development of the method is based on integrating the concepts of ''Systems Analysis'' with the techniques of ''Computer Graphics''. The concepts behind the method are very general in nature. This paper, however, illustrates the application of the method in solving gas well completion design problems. The use of the method will save time and improve the efficiency of such design and analysis problems.

Hart, D.L.

1989-01-01

Two well nests, SF-1 and SF-2, were drilled in Santa Fe County, New Mexico, to monitor the hydraulic head within selected zones of the aquifer. Each well nest consists of three piezometers of shallow, middle, and deep completion within the aquifer. Each set of wells was drilled to a depth of about 2,000 ft before actual construction of the piezometers. Each piezometer was completed using either 5 or 10 ft of wire-wrapped screen. These piezometers were constructed as part of a larger ongoing program with the Santa Fe Metropolitan Water Board and New Mexico State Engineer Office to establish a regional observation-well network and to define better the groundwater flow system in the vicinity of Santa Fe and Santa Fe well fields.

Complete active space configuration interaction from state-averaged configuration interaction singles natural orbitals: Analytic first derivatives and derivative coupling vectors

NASA Astrophysics Data System (ADS)

Fales, B. Scott; Shu, Yinan; Levine, Benjamin G.; Hohenstein, Edward G.

2017-09-01

A new complete active space configuration interaction (CASCI) method was recently introduced that uses state-averaged natural orbitals from the configuration interaction singles method (configuration interaction singles natural orbital CASCI, CISNO-CASCI). This method has been shown to perform as well or better than state-averaged complete active space self-consistent field for a variety of systems. However, further development and testing of this method have been limited by the lack of available analytic first derivatives of the CISNO-CASCI energy as well as the derivative coupling between electronic states. In the present work, we present a Lagrangian-based formulation of these derivatives as well as a highly efficient implementation of the resulting equations accelerated with graphical processing units. We demonstrate that the CISNO-CASCI method is practical for dynamical simulations of photochemical processes in molecular systems containing hundreds of atoms.

Brief: Multizone subsea completions in the Dai Hung field, Vietnam

DOE Office of Scientific and Technical Information (OSTI.GOV)

Lay, K.R.

1996-04-01

The early production phase of the Dai Hung field development involved drilling and completion of five subsea wells. Owing to the complex nature of the reservoirs, selective multizone completions were installed for effective reservoir data acquisition and reservoir management. Downhole completion designs used equipment that was primarily of existing proven design, and downhole equipment was installed in a single trip. Ongoing reservoir management will be aided by use of a subsea wireline system to facilitate data acquisition.

The antibiotic sulfamethoxazole was the most frequently detected CEC, detected in a total of 14 of 123 samples (11.4 percent) by one or both analytical methods that include sulfamethoxazole as an analyte. Most (11 of 14, or 79 percent) of the detections of sulfamethoxazole were in samples from domestic wells or monitoring wells located in areas where septic systems or potentially leaking centralized sewers are prevalent. The chemical N,N-Diethyl-meta-toluamide (DEET) was detected at the highest concentration of any CEC, at 7.9 micrograms per liter. Bisphenol A was detected second most frequently of all chemicals. DEET and Bisphenol A were detected most frequently in wells in proximity to closed landfills. Samples from bedrock wells, most of which are drinking water wells that are deeper than glacial wells, had a higher percentage of wells with CEC detections compared to samples from wells completed in glacial aquifers. The higher dissolved oxygen concentrations and lower specific conductance for the bedrock wells sampled indicate shorter duration flow paths from the land surface to these wells than for wells completed in glacial aquifers.

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

Miskimins, J.L.

2009-05-15

This paper provides an overview of design and life-cycle considerations for certain unconventional-reservoir wells. An overview of unconventional-reservoir definitions is provided. Well design and life-cycle considerations are addressed from three aspects: upfront reservoir development, initial well completion, and well-life and long-term considerations. Upfront-reservoir-development issues discussed include well spacing, well orientation, reservoir stress orientations, and tubular metallurgy. Initial-well-completion issues include maximum treatment pressures and rates, treatment diversion, treatment staging, flowback and cleanup, and dewatering needs. Well-life and long-term discussions include liquid loading, corrosion, refracturing and associated fracture reorientation, and the cost of abandonment. These design considerations are evaluated with case studiesmore » for five unconventional-reservoir types: shale gas (Barnett shale), tight gas (Jonah feld), tight oil (Bakken play), coalbed methane (CBM) (San Juan basin), and tight heavy oil (Lost Hills field). In evaluating the life cycle and design of unconventional-reservoir wells, 'one size' does not fit all and valuable knowledge and a shortening of the learning curve can be achieved for new developments by studying similar, more-mature fields.« less

Ground-water levels in Huron County, Michigan, 2006-07

USGS Publications Warehouse

Weaver, T.L.; Blumer, S.P.; Fuller, L.M.

2008-01-01

In 1990, the U.S. Geological Survey (USGS) completed a study of the hydrogeology of Huron County, Michigan (Sweat, 1991). In 1993, Huron County and the USGS entered into a continuing agreement to measure water levels at selected wells throughout Huron County. As part of the agreement, USGS initially operated four continuous water-level recorders, installed from 1988 to 1991 on wells in Bingham (H5r), Fairhaven (H9r), Grant (H2r), and Lake Townships (H25Ar) and summarized the data collected in an annual or bi-annual report (fig. 1). The agreement was altered in 2003, and beginning January 1, 2004, only wells H9r and H25Ar retained continuous water-level recorders, while wells H2r and H5r reverted to quarterly or periodic measurement status due to budget constraints. The decision of which two wells to discontinue was based on an analysis of the intrinsic value to Huron County of data from each well. Well H2r was selected for periodic measurement at that time because it is completed in the glacial aquifer, which is absent in much of Huron County and well H5r, which is completed in the Marshall aquifer, was selected because the water level in the well is often perturbed as a result of pumpage from nearby production wells and does not always reflect baseline conditions within the aquifer. USGS also has provided training for County or Huron Conservation District personnel to measure the water level in 24 of the wells on a quarterly basis. USGS personnel accompany County or Huron Conservation District personnel on a semi-annual basis to provide a quality assurance/quality control check of all measurements being made. Water-level data collected from the wells is summarized in an annual or bi-annual report. The altitude of Lake Huron and precipitation are good indicators of general climatic conditions and, therefore, provide an environmental context for groundwater levels in Huron County. Figure 2 shows the meanmonthly water-level altitude of Lake Huron, averaged from measurements made at Essexville and Harbor Beach (National Oceanic and Atmospheric Administration, 2008), and monthly precipitation measured in Harbor Beach, Sebewaing, and Bad Axe (National Oceanic and Atmospheric Administration, Danny Costello, written commun., 2007-08). In December 2007, the water level in Lake Huron dropped to a new monthly mean low of 576.38 ft for the period from 1988 through 2007 (the previous lowwater level of 576.57 ft was measured in March 2003). The net decline in the water level of Lake Huron from January 2006 through December 2007 was 0.68 ft. In 2006, annual precipitation measured at Harbor Beach was 3.2 in. above the long-term average of 31.1 in., with 10.6 in. measured during the 2006 growing season (May through August). In 2007, annual precipitation measured at Harbor Beach was 1.4 in. below normal, with 9.7 in. measured during the growing season. In the two wells equipped with continuous waterlevel recorders, the water level rose 0.32 ft from January 1, 2006 to December 31, 2007 in well H9r, but declined 1.11 ft in well H25Ar. Curiously, well H9r is drilled adjacent to Saginaw Bay (Lake Huron), and, as previously noted, there was a 0.68 ft decline in the water level in Saginaw Bay during that period. Twenty four wells were measured on a quarterly or periodic basis from December 2005 through December 2007 (well H26 was destroyed during summer 2007 reducing the total number of wells from 25). These wells are completed in the glacial, Saginaw and Marshall aquifers, and the Coldwater confining unit. Although each quarterly or periodic measurement only provides a “snapshot” water level (measured in ft below land surface, and altitude, in ft above sea level), the data adequately define the generalized water-level trend in the aquifer near the well. Water levels in 6 quarterly-measured wells had net rises ranging from 0.09 to 1.45 ft for the period, while water levels in 18 of the wells had net declines ranging from 0.26 to 2.19 ft (tables 1 and 2; fig. 3). Period-of-record (the time period during which water levels have been measured by U.S. Geological Survey or their cooperators) minimum depths to water (high-water levels) were measured in March and December 2006 in two quarterly-measured wells completed in the Saginaw aquifer in Oliver and Sebewaing Townships, respectively. A period-of-record minimum depth to water was also recorded June 5, 2007 in well H9r, completed in the Michigan Formation/Marshall aquifer in Fairhaven Township. Period-of-record maximum depths to water were measured in September 2007 in two wells completed in the Marshall aquifer in Oliver and Dwight Townships. Notably, water levels in those two wells recovered about 1 to 3 ft between September and December 2007. No period-of-record minimum or maximum depths to water were measured in wells completed in either the glacial aquifer or the Coldwater confining unit from December 2005 through December 2007. Several external factors influence water-level trends including proximity to nearby production wells, amount and timing of precipitation events, evapotranspiration and type of prevalent ground cover, proximity of aquifer to the surface, and hydraulic characteristics of overlying geologic materials.

Engineering estimates of methane emissions from natural gas production have led to varied projections of national emissions. This work reports direct measurements of methane emissions at 190 onshore natural gas sites in the United States (150 production sites, 27 well completion flowbacks, 9 well unloadings, and 4 workovers). For well completion flowbacks, which clear fractured wells of liquid to allow gas production, methane emissions ranged from 0.01 Mg to 17 Mg (mean = 1.7 Mg; 95% confidence bounds of 0.67-3.3 Mg), compared with an average of 81 Mg per event in the 2011 EPA national emission inventory from April 2013. Emission factors for pneumatic pumps and controllers as well as equipment leaks were both comparable to and higher than estimates in the national inventory. Overall, if emission factors from this work for completion flowbacks, equipment leaks, and pneumatic pumps and controllers are assumed to be representative of national populations and are used to estimate national emissions, total annual emissions from these source categories are calculated to be 957 Gg of methane (with sampling and measurement uncertainties estimated at ± 200 Gg). The estimate for comparable source categories in the EPA national inventory is ~1,200 Gg. Additional measurements of unloadings and workovers are needed to produce national emission estimates for these source categories. The 957 Gg in emissions for completion flowbacks, pneumatics, and equipment leaks, coupled with EPA national inventory estimates for other categories, leads to an estimated 2,300 Gg of methane emissions from natural gas production (0.42% of gross gas production).

Weaver, T.L.; Crowley, S.L.; Blumer, S.P.

2006-01-01

In 1990, the U.S. Geological Survey (USGS) completed a study of the hydrogeology of Huron County, Michigan (Sweat, 1991). In 1993, Huron County and the USGS entered into a continuing agreement to measure water levels at selected wells throughout Huron County. As part of the agreement, USGS has operated four continuous water-level recorders, installed from 1988 to 1991 on wells in Bingham, Fairhaven, Grant, and Lake Townships (fig. 1) and summarized the data collected in an annual or bi-annual report. The agreement was altered in 2003, and beginning January 1, 2004, only the wells in Fairhaven and Lake Townships retained continuous waterlevel recorders, while the wells in Grant and Bingham Townships reverted primarily to periodic or quarterly measurement status. USGS also has provided training for County or Huron Conservation District personnel to measure the water level, on a quarterly basis, in 25 wells. USGS personnel regularly accompany County or Huron Conservation District personnel to provide a quality assurance/quality control check of all measurements being made. Water-level data collected from the 25 periodically or quarterly-measured wells is summarized in an annual or bi-annual report. In 1998, the USGS also completed a temporal and spatial analysis of the monitoring well network in Huron County (Holtschlag and Sweat, 1998).The altitude of Lake Huron and precipitation are good indicators of general climatic conditions and, therefore, provide an environmental context for ground-water levels in Huron County. Figure 2 shows the mean-monthly water-level altitude of Lake Huron, averaged from measurements made by the U.S. Army Corps of Engineers at sites near Essexville or Harbor Beach, or both (National Oceanic and Atmospheric Administration, 2003-05), and monthly precipitation measured in Bad Axe (National Oceanic and Atmospheric Administration, 2003-05). In March 2003, a new low-water level for the period from 1991 through 2005 was measured in Lake Huron. There was almost no net change in the water level of Lake Huron from January 2004 through December 2005. In 2004, annual precipitation measured in Port Hope was about 3.7 inches above normal, but precipitation measured in Bad Axe was about 1.4 inches below normal. About 14.5 inches of precipitation was measured in Bad Axe during the 2004 summer growing season (May through August), which is about the same as was measured in Port Hope during the same period. Provisional precipitation totals for 2005 were 30.7 inches for January through November in Port Hope, and about 31.7 inches for the year in Bad Axe. About 10.6 inches of precipitation was measured in Bad Axe during the 2005 summer growing season, which is about 0.2 inches more than was recorded at Port Hope during the same period.Two wells equipped with continuous-data recorders are completed in the Saginaw and Marshall aquifers in Fairhaven and Lake Townships, respectively. From January 2004 through December 2005, the net rise in the water level in the Fairhaven Township well was 0.71 ft, and the net rise in the Lake Township well was 0.98 ft. The Fairhaven Township well is drilled adjacent to Saginaw Bay (Lake Huron), and, as previously noted, there was almost no net change in the water level in Saginaw Bay over the same period. Hydrographs showing water levels are presented for the two wells equipped with continuous-data recorders. Continuous-data recorders were discontinued in the Grant and Bingham Township wells at the end of 2003 due to budget constraints. The decision of which two wells to discontinue was based on an analysis of the intrinsic value to Huron County of data from each well. The Grant Township well was selected for periodic or quarterly measurement at that time because it is completed in the glacial aquifer, which is little used for drinking water purposes or absent in much of Huron County. The Bingham Township well, which is completed in the Marshall aquifer, was selected for periodic or quarterly measurement because water levels in the well are often perturbed as a result of pumpage from nearby production wells and do not reflect baseline conditions within the aquifer.Twenty five wells were measured on a periodic or quarterly basis in 2004-05. These wells are completed in the glacial, Saginaw, and Marshall aquifers, and the Coldwater confining unit. Although each quarterly measurement only provides a “snapshot” water level (measured in feet below land surface), the data adequately define the generalized water-level trend in the aquifer near the well. Water levels in 15 quarterlymeasured wells had a net rise ranging from 0.20 to 1.31 ft for the period from January 2004 to December 2005, while water levels in 10 of the wells had a net decline ranging from 0.07 to 0.99 ft over the same period (fig. 3; table 1). Period-of-record (the time period when water levels have been measured by U.S. Geological Survey or their cooperators) minimum depths to water (high-water levels) were measured in March 2004 in two quarterly-measured wells completed in the Marshall aquifer in Lake and Hume Townships. Period-of-record maximum depths to water were measured in September 2005 in three wells completed in the Marshall aquifer near Bad Axe. Water levels in those three wells recovered about 3 to 5 ft between September and December 2005. No period-of-record minimum or maximum depths to water were measured for the period from January 2004 through December 2005 in wells completed in either the glacial and Saginaw aquifers, or the Coldwater confining unit. Hydrographs showing water levels measured in each well are presented for the 25 wells measured on a quarterly basis.Water-level trends measured for the period from January 2004 through December 2005 in other wells in Lower Michigan have similarities to those measured in Huron County wells. Several external factors influence water-level trends including proximity to nearby production wells, amount and timing of precipitation events, evapotranspiration and type of prevalent ground cover, proximity of aquifer to the surface, and hydraulic characteristics of overlying geologic materials.

van Langenberg, Tanja; Sawyer, Susan M; Le Grange, Daniel; Hughes, Elizabeth K

2016-11-01

Anorexia nervosa (AN) is often first diagnosed in the adolescent years. The treatment with the greatest evidence during this time is family-based treatment (FBT). In FBT, siblings are expected to attend treatment sessions; however, sibling well-being during this time has not been well researched. This study aimed to explore sibling well-being when the ill child was initially diagnosed with AN and after FBT had been completed. Eighty-five parents and 55 siblings of adolescents with AN completed the Strengths and Difficulties Questionnaire at diagnosis. In addition, 88 parents and 46 siblings completed the Strengths and Difficulties Questionnaire after finishing treatment. Mothers and fathers reported siblings to have lower levels of conduct problems in comparison with population norms. Mothers also reported lower levels of prosocial behaviours. Siblings reported higher levels of emotional difficulties and hyperactivity in comparison with their peers. There were no differences in reported psychosocial well-being of siblings between diagnosis and following FBT. Siblings of adolescents with AN have poorer psychosocial adjustment than their peers, both before and after FBT. Clinicians and parents are encouraged to be aware of sibling difficulties and seek additional support if required. Copyright © 2016 John Wiley & Sons, Ltd and Eating Disorders Association.

1979-03-01

In 1973, Northern Natural Gas (NNG) Co.'s Midland exploration and production district acquired a 7-section lease block on a Devonian-Montoya prospect suggested by trend geology and limited seismic data. This acreage block was 2 miles west of the abandoned Hershey field, and included acreage on which the Devonian was tested at noncommercial rates in 1962. Additional seismic data confirmed the presence of a drillable prospect on NNG's acreage block. Engineering analyses of the reservoir characteristics suggested that modern completion and treatment techniques would result in a commercial producer. NNG's management approved the expenditure and the first well was spudded inmore » April, 1977. This well, the No. 1 Hershenson, was completed in Sept., 1977 as the discovery well in the Hershey West (Devonian-Montoya) field for a calculated open flow potential (CAOFP) of 20.5 mmcfd dry gas from perforations at 15,445 to 16,017 ft. The confirmation well, No. 1 Hershenson 6, was spudded in May, 1978, and completed in Oct., 1978, for a CAOFP of 86.3 mmcfd from perforations at 16,000 to 16,624 ft. A third well, No. 1 Maddox-Willbanks 15, was spudded in Nov., 1978. Rediscovered field potential justified construction of a gas processing plant and a 16-mile pipeline.« less

Artesian pressures and water quality in Paleozoic aquifers in the Ten Sleep area of the Bighorn Basin, north-central Wyoming

USGS Publications Warehouse

Cooley, Maurice E.

1986-01-01

The major Paleozoic artesian aquifers, the aquifers most favorable for continued development, in the Ten Sleep area of the Bighorn Basin of Wyoming are the Tensleep Sandstone, the Madison Limestone and Bighorn Dolomite (Madison-Bighorn aquifer), and the Flathead Sandstone. The minor aquifers include the Goose Egg and Park City Formations (considered in the Ten Sleep area to be the lateral equivalent of the Phosphoria Formation) and the Amsden Formation. Most wells completed in the major and minor aquifers flow at the land surface. Wellhead pressures generally are less than 50 pounds per square inch for the Tensleep Sandstone, 150-250 pounds per square inch for the Madison-Bighorn aquifer, and more than 400 pounds per square inch for the Flathead Sandstone. Flowing wells completed in the Madison-Bighorn aquifer and the Flathead Sandstone yield more than 1,000 gallons per minute. The initial test of one well completed in the Madison-Bighorn aquifer indicated a flow rate of 14,000 gallons per minute. Transmissivities range from 500 to 1,900 feet squared per day for the Madison-Bighorn aquifer and from about 90 to 325 feet squared per day for the Tensleep and Flathead Sandstones. Significant secondary permeability from fracturing in the Paleozoic aquifers allows local upward interformational movement of water, and this affects the altitude of the potentiometric surfaces of the Tensleep Sandstone and the Madison-Bighorn aquifer. Water moves upward from the Tensleep and other formations, through the Goose Egg Formation, to discharge at the land surface as springs. Much of the spring flow is diverted for irrigation or is used for rearing fish. Decreases from original well pressures were not apparent in wells completed in the Tensleep Sandstone or in the Madison-Bighorn aquifer in the study area except for a few wells in or near the town of Ten Sleep. Most wells completed in the Flathead Sandstone, which also are open to the Madison-Bighorn aquifer, show a decrease of pressure from the time of completion to 1978. The decrease of pressure is partly the result of water moving from the Flathead Sandstone into the Madison-Bighorn aquifer, which has a lower potentiometric surface than does the Flathead Sandstone, even during the time the wells are not in operation. Pressure in some small-capacity wells completed in the Goose Egg Formation also has decreased near Ten Sleep. Most of the wells, particularly the irrigation wells, show a progressive decrease in pressure during the irrigation season but recover during periods of nonuse. Measurements of the pressure were made principally in 1953, 1962, 1970, and 1975-78. Well water from the Paleozoic aquifers generally contains minimal concentrations of dissolved solids and individual constituents but excessive hardness. Dissolved-solids concentrations of water are less than 300 milligrams per liter in the Tensleep Sandstone and the Madison-Bighorn aquifer, less than 200 milligrams per liter in the Flathead Sandstone, and as much as 450 milligrams per liter in the Goose Egg Formation. Bicarbonate is the major constituent, followed by calcium and magnesium. Relatively large concentrations of sulfate, as much as 490 milligrams per liter, were found, mainly in water from the Goose Egg Formation. The water has low sodium (alkali) and medium salinity; therefore, the water is satisfactory for irrigation and most other uses, if excessive hardness is not a detrimental factor. Wellhead temperatures range from 11 ? to 27.5 ? Celsius (51 ? to 81.5 ? Fahrenheit) within a range in depth of approximately 250 to 4,000 feet. This gives a geothermal gradient of about 0.44 ? Celsius per 100 feet (0.79 ? Fahrenheit per 100 feet).

Assessment of continuous oil resources in the Wolfcamp shale of the Midland Basin, Permian Basin Province, Texas, 2016

Gaswirth, Stephanie B.

2017-03-06

The U.S. Geological Survey completed a geology-based assessment of undiscovered, technically recoverable continuous petroleum resources in the Wolfcamp shale in the Midland Basin part of the Permian Basin Province of west Texas. This is the first U.S. Geological Survey evaluation of continuous resources in the Wolfcamp shale in the Midland Basin. Since the 1980s, the Wolfcamp shale in the Midland Basin has been part of the “Wolfberry” play. This play has traditionally been developed using vertical wells that are completed and stimulated in multiple productive stratigraphic intervals that include the Wolfcamp shale and overlying Spraberry Formation. Since the shift to horizontal wells targeting the organic-rich shale of the Wolfcamp, more than 3,000 horizontal wells have been drilled and completed in the Midland Basin Wolfcamp section. The U.S. Geological Survey assessed technically recoverable mean resources of 20 billion barrels of oil and 16 trillion cubic feet of associated gas in the Wolfcamp shale in the Midland Basin.

Jacobs Engineering Group Inc. (JEG) has been contracted by Environmental Management Operations (EMO) to develop and implement a Groundwater Monitoring Well Assessment Plan for Canal Creek in the Edgewood Area of Aberdeen Proving Ground (APG-EA). The task will be performed under the provisions of Master Agreement 071914-A-D7, Task Order 142133. The project consists of assessing the condition of existing groundwater monitoring wells in the Canal Creek Area prior to a groundwater sampling program. The following Work Plan describes the technical approach that will be used to conduct field work for the project. Integrity of some monitoring wells installed at APG-EAmore » has come into question because of problems with well completions that were detected in wells at the O-field Study Area during a recent sampling event. Because of this, EPA and APG-DSHE officials have requested a well integrity assessment for a percentage of 168 monitoring wells installed at the Canal Creek Study Area(14 by USATHAMA, 152 by USGS). Results of the well assessment will be used to determine if these wells were completed in a fashion that minimizes the potential for either cross-contamination of aquifers or leakage of water from the surface into the well.« less

Effects of a Savoring Intervention on Resilience and Well-Being of Older Adults.

Savoring is the ability to be mindful of positive experiences and to be aware of and regulate positive feelings about these experiences. Previous research has found that savoring interventions can be effective at improving well-being of younger adults, but findings have not been extended to older populations. This pilot study examined the effects of a 1-week savoring intervention on older adults' psychological resilience and well-being (i.e., depressive symptoms and happiness). Participants, 111 adults ages 60 or over, completed measures of resilience, depressive symptoms, and happiness pre- and postintervention as well as 1 month and 3 months after the intervention. Analyses revealed that participants who completed the savoring intervention with high fidelity also reported improvements in resilience, depressive symptoms, and happiness over time. These findings suggest that the savoring intervention has the potential to enhance older adults' resilience and psychological well-being.

Well ER-EC-5 was drilled for the U.S. Department of Energy, National Nuclear Security Administration Nevada Site Office in support of the Nevada Environmental Restoration Project at the Nevada Test Site, Nye County, Nevada. This well was drilled in the summer of 1999 as part of the U.S. Department of Energy's hydrogeologic investigation program in the Western Pahute Mesa - Oasis Valley region just west of the Nevada Test Site. A 44.5-centimeter surface hole was drilled and cased off to a depth of 342.6 meters below ground surface. The borehole diameter was then decreased to 31.1 centimeters for drilling to amore » total depth of 762.0 meters. One completion string with three isolated slotted intervals was installed in the well. A preliminary composite, static water level was measured at the depth of 309.9 meters, 40 days after installation of the completion string. Detailed lithologic descriptions with stratigraphic assignments are included in the report. These are based on composite drill cuttings collected every 3 meters, and 18 sidewall samples taken at various depths below 349.6 meters, supplemented by geophysical log data and results from detailed chemical and mineralogical analyses of rock samples. The well penetrated Tertiary-age tuffs of the Thirsty Canyon Group, caldera moat-filling sedimentary deposits, lava of the Beatty Wash Formation, and landslide breccia and tuffs of the Timber Mountain Group. The well reached total depth in welded ashflow tuff of the Ammonia Tanks Tuff after penetrating 440.1 meters of this unit, which is also the main water-producing unit in the well. The geologic interpretation of data from this well constrains the western margin of the Ammonia Tanks caldera to the west of the well location.« less

Characterizing contaminant concentrations with depth by using the USGS well profiler in Oklahoma, 2003-9

USGS Publications Warehouse

Smith, S. Jerrod; Becker, Carol J.

2011-01-01

In 2007, the USGS well profiler was used to investigate saline water intrusion in a deep public-supply well completed in the Ozark (Roubidoux) aquifer. In northeast Oklahoma, where the Ozark aquifer is known to be susceptible to contamination from mining activities, the well profiler also could be used to investigate sources (depths) of metals contamination and to identify routes of entry of metals to production wells.Water suppliers can consider well rehabilitation as a potential remediation strategy because of the ability to identify changes in contaminant concentrations with depth in individual wells with the USGS well profiler. Well rehabilitation methods, which are relatively inexpensive compared to drilling and completing new wells, involve modifying the construction or operation of a well to enhance the production of water from zones with lesser concentrations of a contaminant or to limit the production of water from zones with greater concentrations of a contaminant. One of the most effective well rehabilitation methods is zonal isolation, in which water from contaminated zones is excluded from production through installation of cement plugs or packers. By using relatively simple and inexpensive well rehabilitation methods, water suppliers may be able to decrease exposure of customers to contaminants and avoid costly installation of additional wells, conveyance infrastructure, and treatment technologies.

Implementation of improved underbalanced drilling in AbuDhabi onshore field

NASA Astrophysics Data System (ADS)

Alhammadi, Adel Mohammed

Abu Dhabi Company for Onshore Oil Operations (ADCO) is considering Underbalanced Drilling (UBD) as a means to develop lower permeability units in its fields. In addition to productivity and recovery gains, ADCO also expects reservoir characterization benefits from UBD. Reservoir screening studies were carried out on all of ADCO's reservoirs to determine their applicability for UBD. The primary business benefits of UBD were determined to be reservoir characterization, damage Mitigation, and rate of Penetration "ROP" Improvement. Apart from the primary benefits, some of the secondary benefits of UBD that were identified beforehand included rig performance. Since it's a trial wells, the challenge was to drill these wells safely, efficiently and of course meeting well objectives. Many operators worldwide drill these well in underbalanced mode but complete it overbalanced. In our case the plan was to drill and complete these wells in underbalanced condition. But we had to challenge most operators and come up with special and unique casing hanger design to ensure well control barriers exists while fishing the control line of the Downhole Deployment Valve "DDV". After intensive studies and planning, the hanger was designed as per our recommendations and found to be effective equipment that optimized the operational time and the cost as well. This report will provide better understanding of UBD technique in general and shade on the special designed casing hanger compared to conventional or what's most used worldwide. Even thought there were some issues while running the casing hanger prior drilling but managed to capture the learning's from each well and re-modified the hanger and come up with better deign for the future wells. Finally, the new design perform a good performance of saving the operation time and assisting the project to be done in a safe and an easy way without a major impact on the well cost. This design helped to drill and complete these wells safely with requirement to kill the wells and this ensured least reservoir damage.

Diagnosis and treatment of orofacial pain in a patient with unserviceable complete dentures: A clinical report.

PubMed

Selecman, Audrey M; Ahuja, Swati A

2018-02-08

An ill-fitting complete denture has the potential to create pain and discomfort as well as conceal or confound the diagnosis of other primary sources of orofacial pain such as trigeminal neuralgia. Guidelines of the American Academy of Orofacial Pain offer an evidence-based approach for the assessment, diagnosis, and management of orofacial pain. A complete and accurate differential diagnosis is paramount to the success of treatment as well as to the circumvention of unnecessary therapy. The purpose of this clinical report was to emphasize an evidence-based approach to the diagnosis and treatment of orofacial pain in a patient with edentulism and a history of prolonged denture wear.

Completed Beltrami-Michell Formulation in Polar Coordinates

NASA Technical Reports Server (NTRS)

Patnaik, Surya N.; Hopkins, Dale A.

2005-01-01

A set of conditions had not been formulated on the boundary of an elastic continuum since the time of Saint-Venant. This limitation prevented the formulation of a direct stress calculation method in elasticity for a continuum with a displacement boundary condition. The missed condition, referred to as the boundary compatibility condition, is now formulated in polar coordinates. The augmentation of the new condition completes the Beltrami-Michell formulation in polar coordinates. The completed formulation that includes equilibrium equations and a compatibility condition in the field as well as the traction and boundary compatibility condition is derived from the stationary condition of the variational functional of the integrated force method. The new method is illustrated by solving an example of a mixed boundary value problem for mechanical as well as thermal loads.

Ground-water levels in Huron County, Michigan, January 1996 through December 1996

USGS Publications Warehouse

Sweat, M.J.

1997-01-01

In 1990, the U.S. Geological Survey (USGS) completed a study of the hydrogeology of Huron County, Michigan (Sweat, 1991). In 1993, Huron County and the USGS entered into an agreement to continue collecting water levels at selected wells throughout Huron County. As part of the agreement, the USGS has provided training and instrumentation for County personnel to measure, on a quarterly basis, the depth to water below the land surface in selected wells. The agreement includes the operation of continuous water-level recorders installed on four wells in Bingham, Fairhaven, Grant and Lake Townships (fig. 1). County personnel make quarterly water-level measurements of 22 other wells. Once each year, County personnel are accompanied by USGS personnel who provide a quality assurance/quality control check of all measurements being made.Precipitation and the altitude of Lake Huron are good indicators of general climatic conditions and, therefore, provide an environmental context for ground-water levels in Huron County. Figure 2 shows the mean monthly water-level altitude of Lake Huron, averaged from measurements made by U.S. Army Corps of Engineers at two sites, and mean monthly precipitation as recorded in Huron County, for the period October 1988 through December 1996. In general, Lake Huron water levels in 1996 were about the same as they were from 1992-94 (NOAA, 1988-96). Precipitation was generally within the normal range, but was lower than 1993 or 1994. Rainfall during May, June, and July was, cumulatively, about 8.5 inches less in 1995 than in 1994.Hydrographs are presented for each of four wells with water-level recorders. Quarterly water-level measurements and range of water levels during 1996 for the other 22 wells are shown graphically and tabulated.In general, water levels in the glaciofluvial aquifer reflect seasonal variations, with maximum depths to water occurring in late summer and early fall and minimum depths to water occurring in late winter and early spring. In general, wells completed in the lower part of the Marshall aquifer continue to show an increase in water-level altitude from the original project period (1988-90); wells completed in the upper part of the Marshall aquifer showed little variation in water-level altitudes compared to previous years. Wells completed in the Saginaw aquifer continued to show higher water level altitudes in 1995, not only near the lake but also farther inland, while water-level altitudes in wells completed in the Coldwater confining unit showed a small increase from the original project period. Water-level altitudes were higher in the southwest and central parts of the County during 1995 than in the previous year, and water-level altitudes were for the most-part unchanged in the northwest, northeast, and southeast parts of the county during 1995. All wells with recorders had lower water levels in September 1995 than in 1993-94. Lower than average precipitation during May-August is the primary reason for lower levels.

In 1990, the U.S. Geological Survey completed a study of the hydrogeology of Huron County, Michigan. In 1993, Huron County and the USGS entered into an agreement to continue collecting water levels at selected wells throughout Huron County. As part of the agreement, the USGS provided training and instrumentation for County personnel to measure, on a quarterly basis, the depth to water below the land surface in selected wells. The program included the operation of continuous water-level recorders installed on four wells, in Bingham, Fairhaven, Grant and Lake townships (figure 1). County personnel make quarterly water-level measurements on 22 other wells (figure 1). Once each year, County personnel are accompanied by USGS personnel who provide a quality assurance/quality control check of all measurements being made.Two of the wells with recorders are completed in the Marshall aquifer (H5r and H25Ar), one is completed in the glacio-fluvial aquifer (H2r), and one is completed in the Saginaw aquifer (H9r). Hydrographs are presented for each of the four wells with water level recorders (figures 3, 4, 6, and 8). Hydrographs of quarterly water-level measurements and range of water levels during the period October, 1988 to January, 1990 (the original project period) are shown in figures 5, 7, 9, and 10 and quarterly water levels are presented in tables 1 through 4.Figure 2 shows the monthly-mean water-level elevation of Lake Huron, as measured at Harbor Beach and Essexville, and monthly-mean precipitation as recorded at Bad Axe, for the period October, 1988 through December, 1994. In general, Lake Huron water-level elevation were at or near record lows in late 1989, and near record highs in late 1993. Precipitation throughout the period was generally within the normal range.

Well-Child Care Redesign: A Mixed Methods Analysis of Parent Experiences in the PARENT Trial.

Parent-focused Redesign for Encounters, Newborns to Toddlers (PARENT), is a well-child care (WCC) model that has demonstrated effectiveness in improving the receipt of comprehensive WCC services and reducing emergency department utilization for children aged 0 to 3 in low-income communities. PARENT relies on a health educator ("parent coach") to provide WCC services; it utilizes a Web-based previsit prioritization/screening tool (Well-Visit Planner) and an automated text message reminder/education service. We sought to assess intervention feasibility and acceptability among PARENT trial intervention participants. Intervention parents completed a survey after a 12-month study period; a 26% random sample of them were invited to participate in a qualitative interview. Interviews were recorded, transcribed, and analyzed using the constant comparative method of qualitative analysis; survey responses were analyzed using bivariate methods. A total of 115 intervention participants completed the 12-month survey; 30 completed a qualitative interview. Nearly all intervention participants reported meeting with the coach, found her helpful, and would recommend continuing coach-led well visits (97-99%). Parents built trusting relationships with the coach and viewed her as a distinct and important part of their WCC team. They reported that PARENT well visits more efficiently used in-clinic time and were comprehensive and family centered. Most used the Well-Visit Planner (87%), and found it easy to use (94%); a minority completed it at home before the visit (18%). Sixty-two percent reported using the text message service; most reported it as a helpful source of new information and a reinforcement of information discussed during visits. A parent coach-led intervention for WCC for young children is a model of WCC delivery that is both acceptable and feasible to parents in a low-income urban population.

Twining, Brian V.; Fisher, Jason C.; Bartholomay, Roy C.

2010-01-01

In 2009, the U.S. Geological Survey in cooperation with the U.S. Department of Energy's Naval Reactors Laboratory Field Office, Idaho Branch Office cored and completed well NRF-16 for monitoring the eastern Snake River Plain (SRP) aquifer. The borehole was initially cored to a depth of 425 feet below land surface and water samples and geophysical data were collected and analyzed to determine if well NRF-16 would meet criteria requested by Naval Reactors Facility (NRF) for a new upgradient well. Final construction continued after initial water samples and geophysical data indicated that NRF-16 would produce chemical concentrations representative of upgradient aquifer water not influenced by NRF facility disposal, and that the well was capable of producing sustainable discharge for ongoing monitoring. The borehole was reamed and constructed as a Comprehensive Environmental Response Compensation and Liability Act monitoring well complete with screen and dedicated pump. Geophysical and borehole video logs were collected after coring and final completion of the monitoring well. Geophysical logs were examined in conjunction with the borehole core to identify primary flow paths for groundwater, which are believed to occur in the intervals of fractured and vesicular basalt and to describe borehole lithology in detail. Geophysical data also were examined to look for evidence of perched water and the extent of the annular seal after cement grouting the casing in place. Borehole videos were collected to confirm that no perched water was present and to examine the borehole before and after setting the screen in well NRF-16. Two consecutive single-well aquifer tests to define hydraulic characteristics for well NRF-16 were conducted in the eastern SRP aquifer. Transmissivity and hydraulic conductivity averaged from the aquifer tests were 4.8 x 103 ft2/d and 9.9 ft/d, respectively. The transmissivity for well NRF-16 was within the range of values determined from past aquifer tests in other wells near NRF of 4.4 x 102 to 5.1 x 105 ft2/d. Water samples were analyzed for metals, nutrients, total organic carbon, volatile organic compounds, semi-volatile organic compounds, herbicides, pesticides, polychlorinated biphenols, and radionuclides. All chloride, nitrate, and sulfate concentrations were less than background concentrations for the eastern SRP aquifer north of the NRF. Concentrations in water samples for most of the organic compounds and radionuclides were less than the reporting limits and reporting levels.

Nondestructive Complete Mechanical Characterization of Zinc Blende and Wurtzite GaAs Nanowires Using Time-Resolved Pump-Probe Spectroscopy.

PubMed

Mante, Pierre-Adrien; Lehmann, Sebastian; Anttu, Nicklas; Dick, Kimberly A; Yartsev, Arkady

2016-08-10

We have developed and demonstrated an experimental method, based on the picosecond acoustics technique, to perform nondestructive complete mechanical characterization of nanowires, that is, the determination of the complete elasticity tensor. By means of femtosecond pump-probe spectroscopy, coherent acoustic phonons were generated in an ensemble of nanowires and their dynamics was resolved. Specific phonon modes were identified and the detection mechanism was addressed via wavelength dependent experiments. We calculated the exact phonon dispersion relation of the nanowires by fitting the experimentally observed frequencies, thus allowing the extraction of the complete elasticity tensor. The elasticity tensor and the nanowire diameter were determined for zinc blende GaAs nanowires and were found to be in a good agreement with literature data and independent measurements. Finally, we have applied this technique to characterize wurtzite GaAs nanowires, a metastable phase in bulk, for which no experimental values of elastic constants are currently available. Our results agree well with previous first principle calculations. The proposed approach to the complete and nondestructive mechanical characterization of nanowires will allow the efficient mechanical study of new crystal phases emerging in nanostructures, as well as size-dependent properties of nanostructured materials.

Prevedel, P.,; Wohlgemuth, L.; Legarth, B.; Henninges, J.; Schütt, H.; Schmidt-Hattenberger, C.; Norden, B.; Förster, A.; Hurter, S.

2009-04-01

This paper reports the CO2SINK drilling and permanent monitoring completions, as well as the well testing techniques applied in Europe's first scientific carbon dioxide onshore storage test in a saline aquifer near the town of Ketzin, 40 km east of Berlin/Germany. Three boreholes, one injection and two observation wells have been drilled in 2007 to a total depth of about 800 m. The wells were completed as "smart" wells containing a variety of permanently installed down-hole sensors, which have successfully proven their functionality during over their first injection year and are the key instruments for the continuous monitoring of the CO2 inside the reservoir during the storage phase. Constructing three wells in close proximity of 50 to 100m distance to each other with a dense sensor and monitoring cable population requires detailed planning and employment of high-end project management tools. All wells were cased with stainless final casings equipped with pre-perforated sand filters in the pay-zone and wired on the outside with two fibre-optical, one multi-conductor copper, and a PU-heating cable to the surface. The reservoir casing section is externally coated with a fibre-glass-resin wrap for electrical insulation of the 15 geo-electrical toroid antennas in the open hole section. A staged cementation program was selected in combination with the application of a newly developed swellable rubber packer technology and specialized cementation down-hole tools. This technology was given preference over perforation work inside the final casing at the reservoir face, which would have created unmanageable risks of potential damage of the outside casing cables. Prior to the start of the injection phase, an extensive production and injection well test program as well as well-to-well interference tests were performed in order to determine the optimum CO2 injection regime.

2013-12-01

After treatment, patients with active cancer face a considerable burden from the effects of both the disease and its treatment. The Palliative Rehabilitation Program (prp) is designed to ameliorate disease effects and to improve the patient's functioning. The present study evaluated predictors of program completion and changes in functioning, symptoms, and well-being after the program. The program received referrals for 173 patients who had finished anticancer therapy. Of those 173 patients, 116 with advanced cancer were eligible and enrolled in the 8-week interprofessional prp; 67 completed it. Measures of physical, nutritional, social, and psychological functioning were evaluated at entry to the program and at completion. Participants experienced significant improvements in physical performance (p < 0.000), nutrition (p = 0.001), symptom severity (p = 0.005 to 0.001), symptom interference with functioning (p = 0.003 to 0.001), fatigue (p = 0.001), and physical endurance, mobility, and balance or function (p = 0.001 to 0.001). Reasons that participants did not complete the prp were disease progression, geographic inaccessibility, being too well (program not challenging enough), death, and personal or unknown reasons. A normal level of C-reactive protein (<10 mg/L, p = 0.029) was a predictor of program completion. Patients living with advanced cancers who underwent the interprofessional prp experienced significant improvement in functioning across several domains. Program completion can be predicted by a normal level of C-reactive protein.

Evaluating Checklist Use in Companion Animal Wellness Visits in a Veterinary Teaching Hospital: A Preliminary Study.

PubMed

Nappier, Michael T; Corrigan, Virginia K; Bartl-Wilson, Lara E; Freeman, Mark; Werre, Stephen; Tempel, Eric

2017-01-01

The number of companion animal wellness visits in private practice has been decreasing, and one important factor cited is the lack of effective communication between veterinarians and pet owners regarding the importance of preventive care. Checklists have been widely used in many fields and are especially useful in areas where a complex task must be completed with multiple small steps, or when cognitive fatigue is evident. The use of checklists in veterinary medical education has not yet been thoroughly evaluated as a potential strategy to improve communication with pet owners regarding preventive care. The authors explored whether the use of a checklist based on the American Animal Hospital Association/American Veterinary Medical Association canine and feline preventive care guidelines would benefit senior veterinary students in accomplishing more complete canine and feline wellness visits. A group of students using provided checklists was compared to a control group of students who did not use checklists on the basis of their medical record notes from the visits. The students using the checklists were routinely more complete in several areas of a wellness visit vs. those who did not use the checklists. However, neither group of students routinely discussed follow-up care recommendations such as frequency or timing of follow-up visits. The study authors recommend considering checklist use for teaching and implementing wellness in companion animal primary care veterinary clinical teaching settings.

Life cycle water consumption and wastewater generation impacts of a Marcellus shale gas well.

PubMed

Jiang, Mohan; Hendrickson, Chris T; VanBriesen, Jeanne M

2014-01-01

This study estimates the life cycle water consumption and wastewater generation impacts of a Marcellus shale gas well from its construction to end of life. Direct water consumption at the well site was assessed by analysis of data from approximately 500 individual well completion reports collected in 2010 by the Pennsylvania Department of Conservation and Natural Resources. Indirect water consumption for supply chain production at each life cycle stage of the well was estimated using the economic input-output life cycle assessment (EIO-LCA) method. Life cycle direct and indirect water quality pollution impacts were assessed and compared using the tool for the reduction and assessment of chemical and other environmental impacts (TRACI). Wastewater treatment cost was proposed as an additional indicator for water quality pollution impacts from shale gas well wastewater. Four water management scenarios for Marcellus shale well wastewater were assessed: current conditions in Pennsylvania; complete discharge; direct reuse and desalination; and complete desalination. The results show that under the current conditions, an average Marcellus shale gas well consumes 20,000 m(3) (with a range from 6700 to 33,000 m(3)) of freshwater per well over its life cycle excluding final gas utilization, with 65% direct water consumption at the well site and 35% indirect water consumption across the supply chain production. If all flowback and produced water is released into the environment without treatment, direct wastewater from a Marcellus shale gas well is estimated to have 300-3000 kg N-eq eutrophication potential, 900-23,000 kg 2,4D-eq freshwater ecotoxicity potential, 0-370 kg benzene-eq carcinogenic potential, and 2800-71,000 MT toluene-eq noncarcinogenic potential. The potential toxicity of the chemicals in the wastewater from the well site exceeds those associated with supply chain production, except for carcinogenic effects. If all the Marcellus shale well wastewater is treated to surface discharge standards by desalination, $59,000-270,000 per well would be required. The life cycle study results indicate that when gas end use is not considered hydraulic fracturing is the largest contributor to the life cycle water impacts of a Marcellus shale gas well.

Chemical changes in an industrial waste liquid during post-injection movement in a limestone aquifer, Pensacola, Florida

USGS Publications Warehouse

Ehrlich, G.G.; Godsy, E.M.; Pascale, C.A.; Vecchioli, John

1979-01-01

An industrial waste liquid containing organonitrile compounds and nitrate ion has been injected into the lower limestone of the Floridan aquifer near Pensacola, Florida since June 1975. Chemical analyses of water from monitor wells and backflow from the injection well indicate that organic carbon compounds are converted to CO2 and nitrate is converted to N2. These transformations are caused by bacteria immediately after injection, and are virtually completed within 100 m of the injection well. The zone near the injection well behaves like an anaerobic filter with nitrate respiring bacteria dominating the microbial flora in this zone.Sodium thiocyanate contained in the waste is unaltered during passage through the injection zone and is used to detect the degree of mixing of injected waste liquid with native water at a monitor well 312 m (712 ft) from the injection well. The dispersivity of the injection zone was calculated to be 10 m (33 ft). Analyses of samples from the monitor well indicate 80 percent reduction in chemical oxygen demand and virtually complete loss of organonitriles and nitrate from the waste liquid during passage from the injection well to the monitor well. Bacterial densities were much lower at the monitor well than in backflow from the injection well.

Egypt`s first remotely controlled subsea completion -- A Gulf of Suez case history

DOE Office of Scientific and Technical Information (OSTI.GOV)

El Hawary, A.; Hoffman, J.G.

1995-11-01

A case history of the Gulf of Suez Petroleum Company`s (GUPCO) first remotely controlled subsea completion is provided. The first completion was for well GS 373-2, a previously drilled and tested exploration well located in the south portion of the Gulf of Suez. Subsea technology was utilized to economically justify development of this one well marginal field which was discovered in 1978. Traditional methods proved to be too costly for development, therefore application of a low cost subsea tree was utilized to capture the resources. In the Gulf of Suez many fields have been discovered by have not been developedmore » due to low reserves. These marginal projects can have a profound impact on the revenue and shareholder value if any economic method is used to exploit these opportunities. Platform installation was not feasible due to reserve size, hence the well has remained abandoned until recently. Capturing the experience of Amoco in the Gulf of Mexico and in the Dutch North Sea, GUPCO was able to build a low cost subsea system which would allow for the economic development of the marginal fields discovered in the past. This paper presents a summarized look at subsea completion technology. The cost comparison of traditional development methods will be made, given the local cost structure in Egypt. The application of this technology has some limitations and constraints which will be discussed in the paper. Furthermore the actual field installation of Egypt`s first remotely controlled subsea tree will be summarized. Also included is a discussion on simple remote controls,and offshore installation operations.« less

Participatory workplace wellness programs: reward, penalty, and regulatory conflict.

PubMed

Pomeranz, Jennifer L

2015-06-01

POLICY POINTS: Workplace wellness programs that provide incentives for completing a health risk assessment are a form of participatory programs. There are legal and ethical concerns when employers assess penalties for not completing a health risk assessment, raising questions about the voluntariness of such a program. The Departments of Treasury, Labor, and Health and Human Services' 2013 regulations for participatory programs and employers' current practices conflict with the Equal Employment Opportunity Commission's prevailing interpretation of the Americans with Disabilities Act of 1990. In keeping with the Patient Protection and Affordable Care Act, Congress revised the law related to workplace wellness programs. In June 2013, the Departments of Treasury, Labor, and Health and Human Services passed the final regulations, updating their 2006 regulatory framework. Participatory programs that reward the completion of a health risk assessment are now the most common type of wellness program in the United States. However, legal and ethical concerns emerge when employers utilize incentives that raise questions about the voluntariness of such programs. At issue is that under the Americans with Disabilities Act (ADA) of 1990, employers cannot require health-related inquiries and exams. To analyze the current interpretation of the ADA, I conducted research on both LexisNexis and federal agency websites. The resulting article evaluates the differences in the language of Congress's enabling legislation and the federal departments' regulations and how they may conflict with the ADA. It also reviews the federal government's authority to address both the legal conflict and ethical concerns related to nonvoluntary participatory programs. Employers' practices and the federal departments' regulations conflict with the current interpretation of the ADA by permitting employers to penalize employees who do not complete a health risk assessment. The departments' regulations may be interpreted as conflicting with Congress's legislation, which mentions penalties only for health-contingent wellness programs. Furthermore, the regulatory protections for employees applicable to health-contingent wellness programs do not apply to participatory programs. Either Congress or the federal agencies should address the conflict among employers' practices, the wellness regulations, and the ADA and also consider additional protections for employees. Employers can avoid ethical and legal complications by offering voluntary programs with positive incentives. © 2015 Milbank Memorial Fund.

Appreciation and implementation of the Krachtvoer healthy diet promotion programme for 12- to 14- year-old students of prevocational schools

PubMed Central

2011-01-01

Background Krachtvoer is a school-based healthy diet programme, developed in 2001 and revised in 2007 to meet the needs of particular segments of the target population as well as a wider target group. The main aims of the present process evaluation of the revised programme were to examine student and teacher appreciation of the programme, completeness of and adherence to its implementation, and relations between appreciation and completeness of implementation. Methods Data were collected among 22 teachers and 1117 students of 13 schools, using student evaluation forms, teacher logbooks, telephone interviews, and classroom observations. Results Results indicate favourable levels of teacher and student appreciation for the programme in general and the revised elements. Girls, first-year students and students with more favourable dietary intakes particularly appreciated individual programme elements. Levels of completeness of implementation were high, but several teachers did not adhere to the intended implementation period. Some moderately strong relations were found between teacher appreciation and completeness of implementation scores. Conclusion We conclude that the revisions have resulted in a programme that was appreciated well, also by the extended target group, and was implemented with a high degree of completeness. Teacher appreciation proved potentially important for completeness of implementation. We identified several aspects requiring improvement, indicating the importance of continued programme updates and repeated evaluation. PMID:22151954

Self-directed learning in gross human anatomy: assessment outcomes and student perceptions.

Smythe, Gayle; Hughes, Diane

2008-01-01

Speech pathology students enrolled in a lecture-based gross human anatomy program completed two out of nine topics in self-directed mode. Student performance in quizzes was compared for the two modes, and the students completed questionnaires on their perceptions of the self-directed mode of delivery. Students performed as well in the first self-directed topic as they did in lecture-based material, but performance declined significantly on the second self-directed topic. Correlations showed that students who performed well in lecture-based topics also performed well on self-directed topics. The major issues that arose in the student questionnaires were primarily related to the amount of content in the topics and the length of time required for completion. We conclude that there is a strong need for appropriate design of distance education materials to reflect student perceptions of length, content, and time investment, and more importantly that there is a need to ensure extensive communication and support of students studying in distance education/self-directed modes for the first time.

Lake Billy Shaw Operations and Maintenance, Final Annual Report 2000.

DOE Office of Scientific and Technical Information (OSTI.GOV)

Dodson, Guy; Pero, Vincent

Lake Billy Shaw is a newly constructed earthen dam reservoir with a surface area of 430 acres. Construction on the dam and structures was complete in November of 1998. The fish screen structures were complete in December of 1998, with initial filling in May 1999. Upon initial filling, dam structures, monitoring wells, fish screen structures, and lake level were monitored daily, with recordings being taken three times/week. During June 1999 the water to the lake was turned off in order to complete additional construction work on the lake. This work included installation of culverts around the perimeter road, installation ofmore » boat launches, finish work on the spillway structure, pumphouse and well protection and planting 4 trees along the entrance to the boat launch area. The water was turned on again in late September 1999 with all structures having been checked, fish screens greased and maintained and well levels being monitored. In 2000 the Operations and Maintenance portion of the project began with monitoring of piezometers, water levels, biological monitoring, riparian plantings, protection of shorelines, and maintenance of structures and appurtances.« less

Rourke, Kevin; Wilson, Coralie J

2017-10-01

To determine if adolescents perceive community-based exercise as beneficial to their well-being and in what ways. A New South Wales Police Citizens Youth Club ran a four-week fitness course. The classes involved: 1) sports including basketball and soccer, 2) non-contact boxing drills, and 3) games, both team games such as dodgeball and non-team games such as line tag. Parental consent to offer a survey at the completion of the course was requested during registration. The survey was the Warwick Edinburgh Mental Well-being Scale; it was minimally modified to measure perceived benefit to mental well-being instead of actual benefit. Thirty-one high school adolescents, ages 13-18, completed the survey. As a group, participants reported that they believed their well-being had improved after the course. The mean score for each survey item showed an improvement in every area of mental well-being for this sample of adolescents. Thirty-two per cent of adolescents reported having less energy. Survey scores indicated a statistically significant improvement in perceived well-being ( p<0.0001). The results of this study suggest that four weeks of community-based exercise improves perceived mental well-being in adolescent participants.

Activity-based identity experiences and their relations to problem behavior and psychological well-being in adolescence.

2007-10-01

The current study explored the associations between activity-based identity experiences and youth outcomes. Participants were 107 high school students and one parent or guardian of each from three communities in a Northeastern state. Youth completed a measure of activity-based identity experiences (Personally Expressive Activities Questionnaire (PEAQ) [Waterman, A. S. (1990). Personal expressiveness: Philosophical and psychological foundations. Journal of Mind and Behavior, 11, 47-74]), as well as measures of psychological well-being, substance use, and delinquency. Parents completed the Child Behavior Checklist [Achenbach, T. M. (1991). Manual for the Child Behavior Checklist/4-18 and 1991 profile. Burlington, VT: University of Vermont Department of Psychiatry]. Together, three identity experiences derived from the PEAQ, personal expressiveness, goal-directed behavior, and flow, were significant predictors of adolescent-reported delinquency and well-being. Goal-directed behavior also uniquely predicted adolescent-reported delinquency and well-being. Suggestions for future research and potential implications for intervention are discussed.

A feasibility study to estimate minimum surface-casing depths of oil and gas wells to prevent ground-water contamination in four areas of western Pennsylvania

USGS Publications Warehouse

Buckwalter, T.F.; Squillace, P.J.

1995-01-01

Hydrologic data were evaluated from four areas of western Pennsylvania to estimate the minimum depth of well surface casing needed to prevent contamination of most of the fresh ground-water resources by oil and gas wells. The areas are representative of the different types of oil and gas activities and of the ground-water hydrology of most sections of the Appalachian Plateaus Physiographic Province in western Pennsylvania. Approximate delineation of the base of the fresh ground-water system was attempted by interpreting the following hydrologic data: (1) reports of freshwater and saltwater in oil and gas well-completion reports, (2) water well-completion reports, (3) geophysical logs, and (4) chemical analyses of well water. Because of the poor quality and scarcity of ground-water data, the altitude of the base of the fresh ground-water system in the four study areas cannot be accurately delineated. Consequently, minimum surface-casing depths for oil and gas wells cannot be estimated with confidence. Conscientious and reliable reporting of freshwater and saltwater during drilling of oil and gas wells would expand the existing data base. Reporting of field specific conductance of ground water would greatly enhance the value of the reports of ground water in oil and gas well-completion records. Water-bearing zones in bedrock are controlled mostly by the presence of secondary openings. The vertical and horizontal discontinuity of secondary openings may be responsible, in part, for large differences in altitudes of freshwater zones noted on completion records of adjacent oil and gas wells. In upland and hilltop topographies, maximum depths of fresh ground water are reported from several hundred feet below land surface to slightly more than 1,000 feet, but the few deep reports are not substantiated by results of laboratory analyses of dissolved-solids concentrations. Past and present drillers for shallow oil and gas wells commonly install surface casing to below the base of readily observed fresh ground water. Casing depths are selected generally to maximize drilling efficiency and to stop freshwater from entering the well and subsequently interfering with hydrocarbon recovery. The depths of surface casing generally are not selected with ground-water protection in mind. However, on the basis of existing hydrologic data, most freshwater aquifers generally are protected with current casing depths. Minimum surface-casing depths for deep gas wells are prescribed by Pennsylvania Department of Environmental Resources regulations and appear to be adequate to prevent ground-water contamination, in most respects, for the only study area with deep gas fields examined in Crawford County.

The Impact of an Incentive on the Use of an Online Self-Directed Wellness and Self-Management Program

Greene, Jessica

2014-01-01

Background Those who pay for health care are increasingly looking for strategies to influence individuals to take a more active role in managing their health. Incenting health plan members and/or employees to participate in wellness programs is a widely used approach. Objective In this study, we examine financial incentives to health plan members to participate in an online self-management/wellness program—US $20 for completing the patient activation measure (PAM) and an additional US $40 for completing 8 learning modules. We examined whether the characteristics of plan members differed by the degree to which they responded to the incentives. Further, we examined whether participation in the wellness program was associated with improvements in PAM scores and changes in health care utilization. Methods This retrospective study compared demographic characteristics and change in PAM scores and health utilization for 144,625 health plan members in 2011. Four groups were compared: (1) those who were offered the incentives but chose not to participate (n=128,634), (2) those who received the initial incentive (PAM only) but did not complete 8 topics (n=7099), (3) those who received both incentives (completing 8 topics but no more) (n=2693), and (4) those who received both incentives and continued using the online program beyond what was required by the incentives (n=6249). Results The vast majority of health plan members did not participate in the program (88.91%, 128,634/144,675). Of those who participated, only 7099 of 16,041 (44.25%) completed the PAM for the first incentive, 2693 (16.79%) completed 8 topics for the second incentive, and 6249 (38.96%) received both incentives and continued using the program beyond the incentive requirements. Nonparticipants were more likely to be men and to have lower health risk scores on average than the other three groups of participants (P<.001). In multivariate regression models, those who used the online program (8 topics or beyond) increased their PAM score by approximately 1 point more than those who only took the PAM and did not use the wellness program (P<.03). In addition, emergency department visits were lower for all groups who responded to any level of the incentive as compared to those who did not (P<.01). No differences were found in other types of utilization. Conclusions The incentive was not sufficient to spark most health plan members to use the wellness program. However, the fact that many program participants went beyond the incentive in their use of the online wellness program suggests that the users of the online program found value in using it, and it was their own internal motivation that stimulated this additional use. Providing an incentive for program participation may be an effective pathway for working with less activated patients, particularly if the program is tailored to the needs of the less activated.

2014-03-01

Patients with human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) frequently experience psychosocial complications in addition to physical illness. Conflicting data on the value of companion dog ownership in minimizing psychosocial distress suggest the need for more research in this field. This study helps to clarify and expand upon previous research on perceived well-being among patients with HIV/AIDS, specifically as it relates to how owning dogs influences the well-being of US military veterans living with HIV/AIDS. Twenty-nine male veterans with a mean age of 52 years who reported having owned a dog since being diagnosed as having HIV/AIDS completed semistructured interviews regarding pet ownership and perceived well-being. Participants also completed a brief survey describing their pets and rating scales that assessed symptoms of depression (nine-question Patient Health Questionnaire-9) and the extent of attachment to their pets (Lexington Attachment to Pets Scale). Descriptive statistics were completed and interview responses were transcribed and examined qualitatively for key themes. The mean Patient Health Questionnaire-9 score of 8.9 (median score of 6) was consistent with mild depressive symptoms, and the mean Lexington Attachment to Pets Scale score was 83.2, indicative of high attachment to one's dog. Veterans reported walking their dogs a mean of 49 minutes/day. Qualitative analysis of the interviews showed that having HIV/AIDS interfered with well-being in three main ways (emotional burden, physical condition, and social isolation). Owning dogs enhanced perceived well-being in four ways (physical activity, companionship, responsibility, and stress reduction). Twenty-eight of the 29 participants (97%) reported that owning dogs was a positive experience. Overall, this study suggests that veterans with HIV/AIDS who own companion dogs believe that it improves their well-being.

The proposed action will consist of drilling one geothermal fluid well for intermittent production testing of 284 days over a three year period. Two disposal wells will initially be drilled to provide disposal of lower volume fluids produced during initial testing. Two additional disposal wells will be drilled, logged, completed, tested, and operated prior to commencement of high volume fluid production. Construction of the proposed action will change the land-use of 2 ha (5 ac) for the test well and each of the injection wells from agriculture or wetlands to resource exploration. Lands will be cleared and erosion and runoffmore » will result. During operation of the well test, the only expected impacts are from venting of gases or flaring of gases and noise. After the tests are completed, the area will be restored as much as possible to its natural condition by revegetation programs using nature species.

Increased oil production and reserves from improved completion techniques in the Bluebell field, Uinta Basin. Quarterly technical report, October 1, 1996--December 31, 1996

DOE Office of Scientific and Technical Information (OSTI.GOV)

Morgan, C.D.

1997-02-01

The objective of this project is to increase oil production and reserves in the Uinta Basin by demonstrating improved completion techniques. Low productivity of Uinta Basin wells is caused by gross production intervals of several thousand feet that contain perforated thief zones, water-bearing zones, and unperforated oil-bearing intervals. Geologic and engineering characterization and computer simulation of the Green River and Wasatch formations in the Bluebell field will determine reservoir heterogeneities related to fractures and depositional trends. This will be followed by drilling and recompletion of several wells to demonstrate improved completion techniques based on the reservoir characterization. Transfer of themore » project results will be an ongoing component of the project. The recompletion of the Michelle Ute 7-1 well commenced and is the first step in the three-well demonstration. As part of the recompletion, the gross productive interval was logged, additional beds were perforated, and the entire interval was stimulated with a three-stage acid treatment. The operator attempted to stimulate the well at high pressure (about 10,000 pounds per square inch (psi) [68,950 kPa]) at three separate packer locations. But at each location the pressure would not hold. As a result, all three stages were pumped at a lower pressure (6500 psi maximum [44,820 kPa]) from one packer location. As of December 31, 1996, the operator was tripping in the hole with the production packer and tubing to begin swab testing the well.« less

When is one layer complete? Using simultaneous in-situ RHEED and x-ray reflectivity to map layer-by-layer thin-film oxide growth

NASA Astrophysics Data System (ADS)

Sullivan, M. C.; Ward, M. J.; Joress, H.; Gutierrez-Llorente, A.; White, A. E.; Woll, A.; Brock, J. D.

2014-03-01

The most popular tool for characterizing in situ layer-by-layer growth is Reflection High-Energy Electron Diffraction (RHEED). X-ray reflectivity can also be used to study layer-by-layer growth, as long as the incident angle of the x-rays is far from a Bragg peak. During layer-by-layer homoepitaxial growth, both the RHEED intensity and the reflected x-ray intensity will oscillate, and each complete oscillation indicates the addition of one layer of material. However, it is well documented, but not well understood, that the maxima in the RHEED intensity oscillations do not necessarily occur at the completion of a layer. In contrast, the maxima in the x-ray intensity oscillations do occur at the completion of a layer, thus the RHEED and x-ray oscillations are rarely in phase. We present our results on simultaneous in situ x-ray reflectivity and RHEED during layer-by-layer growth of SrTiO3 and discuss how to determine the completion of a layer for RHEED oscillations independent of the phase of the RHEED oscillation.

Lack of coordination between health policy and medical education: a contributing factor to the resignation of specialist trainees in Fiji?

PubMed

Oman, Kimberly M; Usher, Kim; Moulds, Rob

2009-03-13

Specialist training was established in Fiji in 1998. This study explored whether health policy, and in particular mismatches between existing policy and the new realities of local specialist training, contributed to decisions by many trainees to ultimately leave the public sectors, often to migrate. Data was collected on the whereabouts of all specialist trainees. Semi-structured interviews were carried out with 36 of 66 Fiji trainees in order to explore reasons for continuing or not completing training, as well as the reasons behind subsequent career choices. Overall, 54.5% of doctors remained in the public sectors or were temporarily overseas. Completion of specialist training was particularly associated with improved retention. Policies that contributed to frustration and sometimes resignations included a lack of transparency in the selection of doctors to enter training pathways, and unreliable career progression following completion of training. Doctors who left training before completion mentioned family stresses, which were exacerbated by delayed age at entry into training and a lack of certainty in regards to the timing of improved working conditions through career advancement. Policy adjustments to expedite entry into training, as well as to establish predictable career progression as a reward for training may increase training completions and overall retention.

Factors Affecting Specific-Capacity Tests and their Application--A Study of Six Low-Yielding Wells in Fractured-Bedrock Aquifers in Pennsylvania

USGS Publications Warehouse

Risser, Dennis W.

2010-01-01

This report by the U.S. Geological Survey, prepared in cooperation with the Pennsylvania Department of Environmental Protection, Bureau of Mining and Reclamation, evaluates factors affecting the application of specific-capacity tests in six low-yielding water wells in areas of coal mining or quarrying in Pennsylvania. Factors such as pumping rate, duration of pumping, aquifer properties, wellbore storage, and turbulent flow were assessed by theoretical analysis and by completing multiple well tests, selected to be representative of low-yielding household-supply wells in areas of active coal mining or quarrying. All six wells were completed in fractured-bedrock aquifers--five in coal-bearing shale, siltstone, sandstone, limestone, and coal of Pennsylvanian and Permian age and one in limestone of Cambrian age. The wells were pumped 24 times during 2007-09 at rates from 0.57 to 14 gallons per minute during tests lasting from 22 to 240 minutes. Geophysical logging and video surveys also were completed to determine the depth, casing length, and location of water-yielding zones in each of the test wells, and seasonal water-level changes were measured during 2007-09 by continuous monitoring at each well. The tests indicated that specific-capacity values were reproducible within about ? 20 percent if the tests were completed at the same pumping rate and duration. A change in pumping duration, pumping rate, or saturated aquifer thickness can have a substantial effect on the comparability of repeated tests. The largest effect was caused by a change in aquifer thickness in well YO 1222 causing specific capacity from repeated tests to vary by a factor of about 50. An increase in the duration of pumping from 60 to 180 minutes caused as much as a 62 percent decrease in specific capacity. The effect of differing pumping rates on specific capacity depends on whether or not the larger rate causes the water level in the well to fall below a major water-yielding zone; when this decline happened at well CA 462, specific capacity was reduced by about 63 percent. Estimates of the maximum yield for low-yielding wells that are computed by multiplying the available drawdown by the specific-capacity value may contain large errors if the wells were pumped at low rates that do not cause much water-level drawdown. The estimates of yield are likely to be too large because the effects of lowering the water level in the well below water-yielding zones have not been incorporated. Better yield estimates can be made by the use of step-drawdown tests or by over-pumping at a rate large enough to dewater most of the wellbore. The maximum well yield, after overpumping, can be estimated from the rate of water-level recovery or by subtracting the incremental rate of change of borehole storage at the end of the test from the pumping rate.

To evaluate the process of survivorship care plan (SCP) completion and to survey oncology staff and primary care physicians (PCPs) regarding challenges of implementing SCPs. Descriptive pilot study. Two facilities in Vermont, an urban academic medical center and a rural community academic cancer center. 17 oncology clinical staff created SCPs, 39 PCPs completed surveys, and 58 patients (breast or colorectal cancer) participated in a telephone survey. Using Journey Forward tools, SCPs were created and presented to patients. PCPs received the SCP with a survey assessing its usefulness and barriers to delivery. Oncology staff were interviewed to assess perceived challenges and benefits of SCPs. Qualitative and quantitative data were used to identify challenges to the development and implementation process as well as patient perceptions of the SCP visit. SCP, healthcare provider perception of barriers to completion and implementation, and patient perception of SCP visit. Oncology staff cited the time required to obtain information for SCPs as a challenge. Completing SCPs 3-6 months after treatment ended was optimal. All participants felt advanced practice professionals should complete and review SCPs with patients. The most common challenge for PCPs to implement SCP recommendations was insufficient knowledge of cancer survivor issues. Most patients found the care plan visit very useful, particularly within six months of diagnosis. Creation time may be a barrier to widespread SCP implementation. Cancer survivors find SCPs useful, but PCPs feel insufficient knowledge of cancer survivor issues is a barrier to providing best follow-up care. Incorporating SCPs in electronic medical records may facilitate patient identification, appropriate staff scheduling, and timely SCP creation. Oncology nurse practitioners are well positioned to create and deliver SCPs, transitioning patients from oncology care to a PCP in a shared-care model of optimal wellness. Institution support for the time needed for SCP creation and review is imperative for sustaining this initiative. Accessing complete medical records is an obstacle for completing SCPs. A 3-6 month window to develop and deliver SCPs may be ideal. PCPs perceive insufficient knowledge of cancer survivor issues as a barrier to providing appropriate follow-up care.

The ability to perform a complete eye examination in the cat is critically important for patients with an ocular disorder or a systemic disease, as well as for the geriatric cat. Cats may need short breaks between portions of the eye exam in order to minimize stress. For the clinician, use of ophthalmic equipment and interpretation of normal vs abnormal findings may take some practice in order to develop proficiency. This review is aimed at veterinary practitioners and outlines all the steps and equipment necessary to perform a complete ophthalmic examination in the cat. Although some specialized equipment is required, a complete eye exam can be performed with a modest investment in equipment and supplies. This article draws on published references for normal parameters measured in the feline eye exam, as well as the experience of the authors. © The Author(s) 2016.

2018-06-04

This study investigated the effects of adolescents' attachment security and reflective functioning (RF) (assessed by the adult attachment interview [AAI]) in the prediction of well-being in adulthood. Adolescents (N = 79; M = 14.6 years old; SD = 3.5 years) completed the AAI at Time 1 (T1), which was subsequently coded for inferred attachment experiences, narrative coherence, and RF by three nonoverlapping teams of raters. Participants completed the Psychological General Well-being Index at T1 and 8 years later (Time 2, T2). Analyses showed that (a) both adolescent narrative coherence and RF were significant predictors of almost all indices of well-being at T2 in adulthood; (b) both narrative coherence and RF indirectly linked inferred loving parental care and T2 well-being; (c) when included in the same model, RF was a significant indirect effect linking inferred loving parental care and T2 well-being. These findings contribute to theory in suggesting that both RF and narrative coherence are predictive of subsequent psychological well-being and operate as links between inferred parental care and subsequent adjustment. Possible mechanisms underlying these findings are discussed.

This study aimed to test the reliability, psychometric, and clinical validity of the use of the Functional Assessment of Cancer Therapy--Brain (FACT-Br) in patients with brain metastases. Patients with brain metastases were interviewed using the FACT-Br (including the FACT-general) 1 week prior to treatment. All patients completed a follow-up assessment 1 month post-treatment. Patients with a good performance status and receiving stereotactic radiosurgery completed an additional 1 week follow-up assessment after the initial baseline interview to assess test-retest reliability. Forty patients had complete 1 month follow-up data. Ten of these patients also completed the 1 week follow-up assessment from baseline. The median Karnofsky performance status of patients was 80 and the median age was 64 years. All subscales of the FACT-Br were found to be conceptually related (except for two correlations) using the following subscales: physical well-being (PWB), social/family well-being (SWB), emotional well-being (EWB), functional well-being (FWB), FACT-G total score, brain cancer subscale (BrC), and the FACT-Br total score. All FACT-Br scores demonstrated excellent reliability, except for the SWB scale which revealed good reliability. The FACT-Br scores showed no significant change in the quality of life (QoL) of patients from baseline to 1 month follow-up. The use of the combined FACT-G and FACT-Br Subscale to assess QoL specifically in patients with brain metastases has successfully undergone psychometric validation. Future clinical trials should use the FACT-G and FACT-Br Subscale to assess QoL in this patient population.

A general framework for complete positivity

NASA Astrophysics Data System (ADS)

Dominy, Jason M.; Shabani, Alireza; Lidar, Daniel A.

2016-01-01

Complete positivity of quantum dynamics is often viewed as a litmus test for physicality; yet, it is well known that correlated initial states need not give rise to completely positive evolutions. This observation spurred numerous investigations over the past two decades attempting to identify necessary and sufficient conditions for complete positivity. Here, we describe a complete and consistent mathematical framework for the discussion and analysis of complete positivity for correlated initial states of open quantum systems. This formalism is built upon a few simple axioms and is sufficiently general to contain all prior methodologies going back to Pechakas (Phys Rev Lett 73:1060-1062, 1994). The key observation is that initial system-bath states with the same reduced state on the system must evolve under all admissible unitary operators to system-bath states with the same reduced state on the system, in order to ensure that the induced dynamical maps on the system are well defined. Once this consistency condition is imposed, related concepts such as the assignment map and the dynamical maps are uniquely defined. In general, the dynamical maps may not be applied to arbitrary system states, but only to those in an appropriately defined physical domain. We show that the constrained nature of the problem gives rise to not one but three inequivalent types of complete positivity. Using this framework, we elucidate the limitations of recent attempts to provide conditions for complete positivity using quantum discord and the quantum data processing inequality. In particular, we correct the claim made by two of us (Shabani and Lidar in Phys Rev Lett 102:100402-100404, 2009) that vanishing discord is necessary for complete positivity, and explain that it is valid only for a particular class of initial states. The problem remains open, and may require fresh perspectives and new mathematical tools. The formalism presented herein may be one step in that direction.

Life Cycle Water Consumption and Wastewater Generation Impacts of a Marcellus Shale Gas Well

PubMed Central

2013-01-01

This study estimates the life cycle water consumption and wastewater generation impacts of a Marcellus shale gas well from its construction to end of life. Direct water consumption at the well site was assessed by analysis of data from approximately 500 individual well completion reports collected in 2010 by the Pennsylvania Department of Conservation and Natural Resources. Indirect water consumption for supply chain production at each life cycle stage of the well was estimated using the economic input–output life cycle assessment (EIO-LCA) method. Life cycle direct and indirect water quality pollution impacts were assessed and compared using the tool for the reduction and assessment of chemical and other environmental impacts (TRACI). Wastewater treatment cost was proposed as an additional indicator for water quality pollution impacts from shale gas well wastewater. Four water management scenarios for Marcellus shale well wastewater were assessed: current conditions in Pennsylvania; complete discharge; direct reuse and desalination; and complete desalination. The results show that under the current conditions, an average Marcellus shale gas well consumes 20 000 m3 (with a range from 6700 to 33 000 m3) of freshwater per well over its life cycle excluding final gas utilization, with 65% direct water consumption at the well site and 35% indirect water consumption across the supply chain production. If all flowback and produced water is released into the environment without treatment, direct wastewater from a Marcellus shale gas well is estimated to have 300–3000 kg N-eq eutrophication potential, 900–23 000 kg 2,4D-eq freshwater ecotoxicity potential, 0–370 kg benzene-eq carcinogenic potential, and 2800–71 000 MT toluene-eq noncarcinogenic potential. The potential toxicity of the chemicals in the wastewater from the well site exceeds those associated with supply chain production, except for carcinogenic effects. If all the Marcellus shale well wastewater is treated to surface discharge standards by desalination, $59 000–270 000 per well would be required. The life cycle study results indicate that when gas end use is not considered hydraulic fracturing is the largest contributor to the life cycle water impacts of a Marcellus shale gas well.

Scott, Tia-Marie; Nystrom, Elizabeth A.; Reddy, James E.

2016-11-04

In a study conducted by the U.S. Geological Survey in cooperation with the New York State Department of Environmental Conservation, groundwater samples were collected from 6 production wells and 7 domestic wells in the Lake Champlain Basin and from 11 production wells and 9 domestic wells in the Susquehanna River Basin in New York. All samples were collected from June through December 2014 to characterize groundwater quality in these basins. The samples were collected and processed using standard procedures of the U.S. Geological Survey and were analyzed for 148 physiochemical properties and constituents, including dissolved gases, major ions, nutrients, trace elements, pesticides, volatile organic compounds, radionuclides, and indicator bacteria.The Lake Champlain Basin study area covers the 3,050 square miles of the basin in northeastern New York; the remaining part of the basin is in Vermont and Canada. Of the 13 wells sampled in the Lake Champlain Basin, 6 are completed in sand and gravel, and 7 are completed in bedrock. Groundwater in the Lake Champlain Basin was generally of good quality, although properties and concentrations of some constituents— fluoride, iron, manganese, dissolved solids, sodium, radon-222, total coliform bacteria, fecal coliform bacteria, and Escherichia coli bacteria—sometimes equaled or exceeded primary, secondary, or proposed drinking-water standards. The constituent most frequently detected in concentrations exceeding drinking-water standards (5 of 13 samples) was radon-222.The Susquehanna River Basin study area covers the entire 4,522 square miles of the basin in south-central New York; the remaining part of the basin is in Pennsylvania. Of the 20 wells sampled in the Susquehanna River Basin, 11 are completed in sand and gravel, and 9 are completed in bedrock. Groundwater in the Susquehanna River Basin was generally of good quality, although properties and concentrations of some constituents—pH, chloride, sodium, dissolved solids, iron, manganese, aluminum, arsenic, barium, gross-alpha radioactivity, radon-222, methane, total coliform bacteria, and fecal coliform bacteria—sometimes equaled or exceeded primary, secondary, or proposed drinking-water standards. As in the Lake Champlain Basin, the constituent most frequently detected in concentrations exceeding drinking-water standards (13 of 20 samples) was radon-222.

Evaluation of Vipassana Meditation Course Effects on Subjective Stress, Well-being, Self-kindness and Mindfulness in a Community Sample: Post-course and 6-month Outcomes.

PubMed

Szekeres, Roberta A; Wertheim, Eleanor H

2015-12-01

Residential Vipassana meditation courses, which teach mindfulness skills, are widely available globally but under-evaluated. This study examined effects of a standardized, community-based Vipassana course, on subjective stress, well-being, self-kindness and trait mindfulness in a community sample. Participants completed self-report measures of these variables at pre-course and post-course (n = 122), and outcomes were compared to a control group of early enrollers (EEs) (n = 50) who completed measures at parallel time points before course commencement. Six-month follow-up was undertaken in the intervention group (n = 90). Findings, including intention-to-complete analyses, suggested positive effects of the Vipassana course in reducing subjective stress and increasing well-being, self-kindness and overall mindfulness (present-moment awareness and non-reaction). Although some reductions in post-course gains were found at follow-up, particularly in stress, follow-up scores still showed improvements compared to pre-course scores. Mindfulness change scores between pre-course and 6-month follow-up were moderately to highly correlated with outcome variable change scores, consistent with the idea that effects of the Vipassana course on stress and well-being operate, at least partially, through increasing mindfulness. The present research underscores the importance of undertaking further investigations into Vipassana courses' effects and applications. Copyright © 2014 John Wiley & Sons, Ltd.

Digital Accessible Knowledge and well-inventoried sites for birds in Mexico: baseline sites for measuring faunistic change.

Peterson, A Townsend; Navarro-Sigüenza, Adolfo G; Martínez-Meyer, Enrique

2016-01-01

Faunal change is a basic and fundamental element in ecology, biogeography, and conservation biology, yet vanishingly few detailed studies have documented such changes rigorously over decadal time scales. This study responds to that gap in knowledge, providing a detailed analysis of Digital Accessible Knowledge of the birds of Mexico, designed to marshal DAK to identify sites that were sampled and inventoried rigorously prior to the beginning of major global climate change (1980). We accumulated DAK records for Mexican birds from all relevant online biodiversity data portals. After extensive cleaning steps, we calculated completeness indices for each 0.05° pixel across the country; we also detected 'hotspots' of sampling, and calculated completeness indices for these broader areas as well. Sites were designated as well-sampled if they had completeness indices above 80% and >200 associated DAK records. We identified 100 individual pixels and 20 broader 'hotspots' of sampling that were demonstrably well-inventoried prior to 1980. These sites are catalogued and documented to promote and enable resurvey efforts that can document events of avifaunal change (and non-change) across the country on decadal time scales. Development of repeated surveys for many sites across Mexico, and particularly for sites for which historical surveys document their avifaunas prior to major climate change processes, would pay rich rewards in information about distributional dynamics of Mexican birds.

To examine the association between attending a well-woman clinic in the prior 2 years and obtaining the human papillomavirus (HPV) vaccine for their 9-17-year-old child. Women (n=1256) who attended reproductive health clinics during September 2011 to February 2013 and had ≥1 children 9-17 years of age were asked to complete a self-administered questionnaire containing questions on demographic characteristics, prior well-woman visits, HPV awareness, and HPV vaccine intent and uptake among their adolescent children. Nearly 78% of women reported having undergone a well-woman visit during the past 2 years. Bivariate analysis showed that the HPV vaccine initiation (23.9% vs. 14.0%, P=.004) and completion (13.6% vs. 6.7%, P=.011) among 9-17 daughters differed between mothers who did or did not have a well-woman visit during the past 2 years. However, intent to vaccinate them (47.2% vs. 53.3%, P=.173) did not differ between these two groups. With regard to 9-17 year old sons, vaccine initiation (10.1% vs. 9.6%, P=.871), completion (4.6% vs. 2.4%, P=.273) and intent to vaccinate (47.3% vs. 52.1%, P=.311) did not differ between these two groups. Multivariable logistic regression analyses confirmed the findings of these bivariate analyses after adjusting for confounder variables. The well-woman visit may be a missed opportunity for physicians to educate their patients about the benefits of HPV vaccination for their adolescent children in general and sons in particular. Intervention studies are warranted to assess the benefits of using this setting to improve HPV vaccine uptake in the US. Copyright © 2013 Elsevier Ltd. All rights reserved.

Successfully completed in 1982, the Tuna field in Australia's Gippsland basin was the most complex of the fields developed by Esso in that area. The commercial oil and gas reserves are contained in four sets of reservoirs in the Upper Cretaceous to Eocene Latrobe group sediments in a faulted and partly eroded anticlinal closure. Some of these reservoirs were not discovered until the development phase of drilling, causing significant changes to the initial development plan, notably the installation of multiple completions in 13 wells. The types of completions used were single, tandem, dual, and dual/tandem.

Petroleum Brasileiro SA has extended several water depth records for subsea technology during a pilot project in giant Marlim oil field in the Campos basin off Brazil. Petrobras finished the 10 well Marlim pilot last December. The field's pilot phase was intended to begin early production and enable Petrobras to gather more reservoir data. Ten satellite wells, including two prepilot wells, were completed during the Marlim pilot phase with guidelineless (GLL) wet christmas trees designed and fabricated by FMC Corp., Houston, and CBV Industrial Mechanic SA, Rio de Janeiro. The subsea wells are producing 52,000 b/d of oil and 21.19more » MMCfd of gas in water depths of 1,847-2,562 ft. Marlim pilot well flow is routed to a permanent semisubmersible floating production system (FPS). Oil moves from the FPS to a monobuoy that offloads to a shuttle tanker. In addition to marking the first successful uses of purpose-built GLL wet trees, FMC said the Marlim pilot project allowed GLL subsea technology to evolve from conceptual status into a proven deepwater completion method.

2014-05-01

The injection of CO2 at the Ketzin pilot site in Germany ended after five years in August 2013. We present the key results from site operation and outline future activities within the post-closure phase. From June 2008 onwards, a total amount of 67 kt of CO2 was safely injected into a saline aquifer (Upper Triassic sandstone) at a depth of 630 m - 650 m. The CO2 used was mainly of food grade quality (purity > 99.9%). In addition, 1.5 kt of CO2 from the pilot capture facility "Schwarze Pumpe" (power plant CO2 with purity > 99.7%) was injected in 2011. During regular operation, the CO2 was pre-heated on-site to 45°C before injection in order to avoid pressure build-up within the reservoir. During the final months of injection a "cold-injection" experiment with a stepwise decrease of the injection temperature down to 10°C was conducted between March and July 2013. In summer 2013, the injection of a mixture of 95% CO2 and 5% N2 was also tested. After ceasing the injection in August the injection facility and pipeline were removed in December 2013. Geological storage of CO2 at the Ketzin pilot site has so far proceeded in a safe and reliable manner. As a result of one of the most comprehensive R&D programs worldwide, a combination of different geochemical and geophysical monitoring methods is able to detect even small quantities of CO2 and map their spatial extent. After the cessation of CO2 injection a series of activities and further investigations are involved in the post-closure phase. The aim is that Ketzin will for the first time ever close the complete life-time cycle of a CO2 storage site at pilot scale. The five wells (1 injection/observation well, 4 pure observation wells) will be successively abandoned within the next few years while monitoring is continuing. The partial plugging of one observation well in the reservoir section was already completed in fall 2013. The new four-years project COMPLETE (CO2 post-injection monitoring and post-closure phase at the Ketzin pilot site) started in January 2014. Activities within COMPLETE include R&D work on well integrity, post-closure monitoring as well as two field experiments. One is a back-production test of the CO2 aiming at information on the physicochemical properties of the back-produced CO2 as well as the pressure response of the reservoir. The other experiment will focus on brine injection into the CO2 storage reservoir in order to study e.g. the residual gas saturation. Public outreach has been a key element for the project from the very beginning and accompanies the research on CO2 storage at Ketzin since 2004. Thus dissemination (e.g. www.co2ketzin.de) and activities at the visitor centre at the pilot site will continue within COMPLETE and along the entire life cycle of the Ketzin project.

Malinowksi, Richard

2007-01-01

The Entiat 4-mile Wells (Entiat 4-mile) project is located in the Entiat subbasin and will benefit Upper Columbia steelhead, spring Chinook and bull trout. The goal of this project is to prevent juvenile fish from being diverted into an out-of-stream irrigation system and to eliminate impacts due to the annual maintenance of an instream pushup dam. The objectives include eliminating a surface irrigation diversion and replacing it with two wells, which will provide Bonneville Power Administration (BPA) and the Bureau of Reclamation (Reclamation) with a Federal Columbia River Power System (FCRPS) BiOp metric credit of one. Wells were chosen overmore » a new fish screen based on biological benefits and costs. Long-term biological benefits are provided by completely eliminating the surface diversion and the potential for fish entrainment in a fish screen. Construction costs for a new fish screen were estimated at $150,000, which does not include other costs associated with implementing and maintaining a fish screening project. Construction costs for a well were estimated at $20,000 each. The diversion consisted of a pushup dam that diverted water into an off-channel pond. Water was then pumped into a pressurized system for irrigation. There are 3 different irrigators who used water from this surface diversion, and each has multiple water right claims totaling approximately 5 cfs. Current use was estimated at 300 gallons per minute (approximately 0.641 cfs). Some irrigated acreage was taken out of orchard production less than 5 years ago. Therefore, approximately 6.8 acre-feet will be put into the State of Washington Trust Water Right program. No water will be set aside for conservation savings. The construction of the two irrigation wells for three landowners was completed in September 2006. The Lower Well (Tippen/Wick) will produce up to 175 gpm while the Upper Well (Griffith) will produce up to 275 gpm during the irrigation season. The eight inch diameter wells were developed to a depth of 75 feet and 85 feet, respectively, and will be pumped with Submersible Turbine pumps. The irrigation wells have been fitted with new electric boxes and Siemens flowmeters (MAG8000).« less

Analysis of the capability to effectively design complementary metal oxide semiconductor integrated circuits

NASA Astrophysics Data System (ADS)

McConkey, M. L.

1984-12-01

A complete CMOS/BULK design cycle has been implemented and fully tested to evaluate its effectiveness and a viable set of computer-aided design tools for the layout, verification, and simulation of CMOS/BULK integrated circuits. This design cycle is good for p-well, n-well, or twin-well structures, although current fabrication technique available limit this to p-well only. BANE, an integrated layout program from Stanford, is at the center of this design cycle and was shown to be simple to use in the layout of CMOS integrated circuits (it can be also used to layout NMOS integrated circuits). A flowchart was developed showing the design cycle from initial layout, through design verification, and to circuit simulation using NETLIST, PRESIM, and RNL from the University of Washington. A CMOS/BULK library was designed and includes logic gates that were designed and completely tested by following this flowchart. Also designed was an arithmetic logic unit as a more complex test of the CMOS/BULK design cycle.

The recommended extent of surgery for well-differentiated thyroid carcinoma has been modified considerably in the updated 2015 American Thyroid Association guidelines published in January 2016. To date, the changes in clinical practice after publication of these new guidelines have not been demonstrated. The aim of this study was to evaluate clinical practice changes associated with implementation of the updated guidelines on the surgical procedure rates of total thyroidectomy, thyroid lobectomy, and completion thyroidectomy at a single tertiary medical center. This is a retrospective cohort study of 169 patients at the Hadassah-Hebrew University Medical Center, Jerusalem, Israel. Patients with pathologically proved, well-differentiated thyroid carcinoma who underwent surgery between January 1, 2013, and December 31, 2014, were compared with patients who underwent surgery from January 1 to December 31, 2016. A total of 434 thyroidectomy procedures were performed during the study period, and 251 had pathologically proved, well-differentiated thyroid carcinoma. Patients with tumors larger than 4 cm, involved lymph nodes, or bilateral nodules were excluded. Primary outcomes were the rate of up-front total thyroidectomy vs lobectomy and the rates of completion thyroidectomy before and after the implementation of the new guidelines. Of the 169 patients in the final analysis, 118 (69.8%) were included from 2013 to 2014 and 51 (30.2%) in 2016. The mean (SD) age for the entire cohort was 44 (13.8) years, and 129 (76.3%) were women. Up-front total thyroidectomy was performed in 72 of 118 patients (61.0%) prior to the 2015 American Thyroid Association guidelines and 16 of 51 (31.4%) following their implementation (odds ratio, 0.29; 95% CI, 0.14-0.59). The rate of completion thyroidectomy also significantly decreased between these periods (73.9% vs 20.0%; odds ratio, 0.09; 95% CI, 0.04-0.19). The updated 2015 American Thyroid Association guidelines implementation was associated with a significant decrease in the rates of both up-front total thyroidectomy and completion thyroidectomy. According to these findings, only 1 of 5 patients who undergoes thyroid lobectomy will require a completion procedure.

Anxiety disorders are the most commonly reported form of mental health problem among youth, but they often go undiagnosed and untreated. This study examined the relationship between burn-injured youths' self-reported anxiety levels, as compared with their parent's perceptions of their child's emotional well-being. Burn-injured children were invited to voluntarily complete the Child Version of the 41-item survey, Screen for Child Anxiety Related Disorders, which consists of five anxiety subscales as well as a Total Anxiety Score. Parents were invited to complete the Parent Version. Sixty-three parent-child dyads, with girls (57%) and boys (43%), completed surveys. Mothers (73%) fathers (16%), and other caregivers (11%) participated. Youth mean age was 12.63 years and 60% reported visible burn scars. Matched-pairs t-tests were used to compare parent and child reports. Significantly lower mean scores were found between Screen for Child Anxiety Related Disorders Total Anxiety Score--Parent mean score of 10.52 vs the Youth mean score 21.06 (P<.001), as well as on all subscales including; panic disorder/somatic symptoms (P<.001), generalized anxiety disorder (P=.004), social anxiety disorder (separation anxiety (P<.001), and school avoidance (P<0.001). Results indicate that parents may be severely underestimating the psychological well-being of burn-injured youth. Findings emphasize the importance of a comprehensive approach in assessment for anxiety, involving the collection of feedback from both child and parent. Asking children for input into their psychological well-being is important. This study reinforces the need for a course of ongoing patient and parent education.

The aims of this study is to carry out a long-term follow-up evaluation of a well-established therapeutic community treatment for addictions in Navarre (Spain) and to make a comparison between the program completers and the dropouts, as well as between relapsing and nonrelapsing patients, on a broad set of variables. A long-term follow-up design (mean of 6 years after leaving treatment) was used to analyze the outcomes of the therapeutic program. The sample consisted of 155 subjects (113 completers and 42 dropouts). A personal interview was carried out with each one of the located subjects. The interviews took place between September 2000 and September 2004. Treatment "dropouts" manifested a higher and earlier rate both of relapses, and of new treatments for their drug addiction than the completion group. The program was also effective in reducing criminal behavior and improving the state of health. Significant differences were found across outcome variables when comparison was made between treatment completers and "dropouts." All subjects improved on outcome variables after receiving the treatment. When relapsing and nonrelapsing patients were compared, significant outcome differences were also found between groups. The study's limitations are noted and future needed research is suggested.

Adult age differences in perceptually based, but not conceptually based implicit tests of memory.

Small, B J; Hultsch, D F; Masson, M E

1995-05-01

Implicit tests of memory assess the influence of recent experience without requiring awareness of remembering. Evidence concerning age differences on implicit tests of memory suggests small age differences in favor of younger adults. However, the majority of research examining this issue has relied upon perceptually based implicit tests. Recently, a second type of implicit test, one that relies upon conceptually based processes, has been identified. The pattern of age differences on this second type of implicit test is less clear. In the present study, we examined the pattern of age differences on one conceptually based (fact completion) and one perceptually based (stem completion) implicit test of memory, as well as two explicit tests of memory (fact and word recall). Tasks were administered to 403 adults from three age groups (19-34 years, 58-73 years, 74-89 years). Significant age differences in favor of the young were found on stem completion but not fact completion. Age differences were present for both word and fast recall. Correlational analyses examining the relationship of memory performance to other cognitive variables indicated that the implicit tests were supported by different components than the explicit tests, as well as being different from each other.

Gaines, Sidney (Walter Reed Army Institute of Research, Washington, D.C.), Julius A. Currie, and Joseph G. Tully. Factors affecting formation of incomplete Vi antibody in mice. J. Bacteriol. 90:635–642. 1965.—Single immunizing doses of purified Vi antigen elicited complete and incomplete Vi antibodies in BALB/c mice, but only incomplete antibody in Cinnamon mice. Three of six other mouse strains tested responded like BALB/c mice; the remaining three, like Cinnamon mice. Varying the quantity of antigen injected or the route of administration failed to stimulate the production of detectable complete Vi antibody in Cinnamon mice. Such antibody was evoked in these animals by multiple injections of Vi antigen or by inoculating them with Vi-containing bacilli or Vi-coated erythrocytes. The early protection afforded by serum from Vi-immunized BALB/c mice coincided with the appearance of incomplete Vi antibody, 1 day prior to the advent of complete antibody. Persistence of incomplete as well as complete antibody in the serum of immunized mice was demonstrated for at least 56 days after injection of 10 μg of Vi antigen. Incomplete Vi antibody was shown to have blocking ability, in vitro bactericidal activity, and the capability of protecting mice against intracerebral as well as intraperitoneal challenge with virulent typhoid bacilli. Production of incomplete and complete Vi antibodies was adversely affected by immunization with partially depolymerized Vi antigens. PMID:16562060

Geochemistry, Comparative Analysis, and Physical and Chemical Characteristics of the Thermal Waters East of Hot Springs National Park, Arkansas, 2006-09

Kresse, Timothy M.; Hays, Phillip D.

2009-01-01

A study was conducted by the U.S Geological Survey in cooperation with the Arkansas State Highway and Transportation Department to characterize the source and hydrogeologic conditions responsible for thermal water in a domestic well 5.5 miles east of Hot Springs National Park, Hot Springs, Arkansas, and to determine the degree of hydraulic connectivity between the thermal water in the well and the hot springs in Hot Springs National Park. The water temperature in the well, which was completed in the Stanley Shale, measured 33.9 degrees Celsius, March 1, 2006, and dropped to 21.7 degrees Celsius after 2 hours of pumping - still more than 4 degrees above typical local groundwater temperature. A second domestic well located 3 miles from the hot springs in Hot Springs National Park was discovered to have a thermal water component during a reconnaissance of the area. This second well was completed in the Bigfork Chert and field measurement of well water revealed a maximum temperature of 26.6 degrees Celsius. Mean temperature for shallow groundwater in the area is approximately 17 degrees Celsius. The occurrence of thermal water in these wells raised questions and concerns with regard to the timing for the appearance of the thermal water, which appeared to coincide with construction (including blasting activities) of the Highway 270 bypass-Highway 70 interchange. These concerns were heightened by the planned extension of the Highway 270 bypass to the north - a corridor that takes the highway across a section of the eroded anticlinal complex responsible for recharge to the hot springs of Hot Springs National Park. Concerns regarding the possible effects of blasting associated with highway construction near the first thermal well necessitated a technical review on the effects of blasting on shallow groundwater systems. Results from available studies suggested that propagation of new fractures near blasting sites is of limited extent. Vibrations from blasting can result in rock collapse for uncased wells completed in highly fractured rock. However, the propagation of newly formed large fractures that potentially could damage well structures or result in pirating of water from production wells appears to be of limited possibility based on review of relevant studies. Characteristics of hydraulic conductivity, storage, and fracture porosity were interpreted from flow rates observed in individual wells completed in the Bigfork Chert and Stanley Shale; from hydrographs produced from continuous measurements of water levels in wells completed in the Arkansas Novaculite, the Bigfork Chert, and Stanley Shale; and from a potentiometric-surface map constructed using water levels in wells throughout the study area. Data gathered from these three separate exercises showed that fracture porosity is much greater in the Bigfork Chert relative to that in the Stanley Shale, shallow groundwater flows from elevated recharge areas with exposures of Bigfork Chert along and into streams within the valleys formed on exposures of the Stanley Shale, and there was no evidence of interbasin transfer of groundwater within the shallow flow system. Fifteen shallow wells and two cold-water springs were sampled from the various exposed formations in the study area to characterize the water quality and geochemistry for the shallow groundwater system and for comparison to the geochemistry of the hot springs in Hot Springs National Park. For the quartz formations (novaculite, chert, and sandstone formations), total dissolved solids concentrations were very low with a median concentration of 23 milligrams per liter, whereas the median concentration for groundwater from the shale formations was 184 milligrams per liter. Ten hot springs in Hot Springs National Park were sampled for the study. Several chemical constituents for the hot springs, including pH, total dissolved solids, major cations and anions, and trace metals, show similarity with the shale formations

To evaluate the effectiveness of in-person versus online Girl Scout leader wellness training for implementation of wellness-promoting practices during troop meetings (phase I) and to assess training adoption and current practices across the council (phase II). Pragmatic superiority trial (phase 1) followed by serial cross-sectional study (phase II). Girl Scout troop meetings in Northeast Kansas. Eighteen troop leaders from 3 counties (phase 1); 113 troop leaders from 7 counties (phase II). Phase I: Troop leaders attended 2 wellness training sessions (first in groups, second individually), wherein leaders set wellness-promoting practice implementation goals, self-monitored progress, and received guidance and resources for implementation. Leaders received the intervention in person or online. Phase I: At baseline and postintervention, leaders completed a wellness-promoting practice implementation questionnaire assessing practices during troop meetings (max score = 11). Phase II: Leaders completed a survey about typical troop practices and interest in further training. Phase I: Generalized linear mixed modeling. Phase I: In-person training increased wellness-promoting practice implementation more than online training (in person = 2.1 ± 1.8; online = 0.2 ± 1.2; P = .022). Phase II: Fifty-six percent of leaders adopted the training. For 8 of 11 wellness categories, greater than 50% of leaders employed wellness-promoting practices. In-person training was superior to online training for improvements in wellness-promoting practices. Wellness training was adopted by the majority of leaders across the council.

Centeredness Theory: Understanding and Measuring Well-Being Across Core Life Domains

Bloch-Jorgensen, Zephyr T.; Cilione, Patrick J.; Yeung, William W. H.; Gatt, Justine M.

2018-01-01

Background: Centeredness Theory (CT) is proposed as a new mental health paradigm that focuses on well-being at a systems-level, across the core life domains of the self, the family unit, relationships, community, and work. The current studies aimed to validate the psychometric properties of a new scale that measures CT against existing well-being and mental health measures. Methods: Study 1 included 488 anonymous online respondents (46% females, 28% males, 25% unknown with median age between 31 and 35 years) across 38 countries who completed the CT scale. Study 2 included 49 first-year psychology students (90% females, mean age of 19 years) from Sydney Australia that completed the CT scale and other well-being and mental health questionnaires at baseline and 2-weeks follow-up. Results: Exploratory and confirmatory factor analyses resulted in a refined 60-item CT scale with five domains, each with four sub-domains. The CT scale demonstrated good internal consistency reliability and test-retest reliability, and showed evidence of convergent validity against other well-being measures (e.g., COMPAS-W Wellbeing Scale, SWLS scale, and Ryff's Psychological Well-being scale). Conclusions: The CT scale appears to be a reliable measure of well-being at a systems-level. Future studies need to confirm these findings in larger heterogeneous samples. PMID:29765344

Family education programmes aim to improve the well-being of carers of people with a mental illness. We evaluated the effectiveness of one such programme, Well Ways, in reducing negative care-giving consequences. We employed a pre-post design to evaluate the effectiveness of Well Ways in a naturalistic setting using a sample of carers of people with a mental illness. The Involvement Evaluation Questionnaire, a measure of care-giving consequences including worrying, tension, urging and supervision, and incorporating the General Health Questionnaire-12 (GHQ-12), was completed by 459 carers before and after participation in Well Ways. Participants' worrying, tension, urging and distress (GHQ-12) were significantly lower following completion of the programme. These improvements were maintained at 3 and 6 month follow up. Carers of people with a psychotic disorder experienced significantly greater reductions in worrying than did other carers. Females reported significantly greater reductions in tension than did males. Findings indicated support for the effectiveness of the Well Ways programme in reducing negative care-giving consequences for families of people with a mental illness. Given the evidence of poor psychological health and negatively appraised family relationships observed at baseline, these findings highlight the need for programmes such as Well Ways.

Hydrogeology and water quality of the Floridan aquifer system and effect of Lower Floridan aquifer withdrawals on the Upper Floridan aquifer at Barbour Pointe Community, Chatham County, Georgia, 2013

USGS Publications Warehouse

Gonthier, Gerard; Clarke, John S.

2016-06-02

Two test wells were completed at the Barbour Pointe community in western Chatham County, near Savannah, Georgia, in 2013 to investigate the potential of using the Lower Floridan aquifer as a source of municipal water supply. One well was completed in the Lower Floridan aquifer at a depth of 1,080 feet (ft) below land surface; the other well was completed in the Upper Floridan aquifer at a depth of 440 ft below land surface. At the Barbour Pointe test site, the U.S. Geological Survey completed electromagnetic (EM) flowmeter surveys, collected and analyzed water samples from discrete depths, and completed a 72-hour aquifer test of the Floridan aquifer system withdrawing from the Lower Floridan aquifer.Based on drill cuttings, geophysical logs, and borehole EM flowmeter surveys collected at the Barbour Pointe test site, the Upper Floridan aquifer extends 369 to 567 ft below land surface, the middle semiconfining unit, separating the two aquifers, extends 567 to 714 ft below land surface, and the Lower Floridan aquifer extends 714 to 1,056 ft below land surface.A borehole EM flowmeter survey indicates that the Upper Floridan and Lower Floridan aquifers each contain four water-bearing zones. The EM flowmeter logs of the test hole open to the entire Floridan aquifer system indicated that the Upper Floridan aquifer contributed 91 percent of the total flow rate of 1,000 gallons per minute; the Lower Floridan aquifer contributed about 8 percent. Based on the transmissivity of the middle semiconfining unit and the Floridan aquifer system, the middle semiconfining unit probably contributed on the order of 1 percent of the total flow.Hydraulic properties of the Upper Floridan and Lower Floridan aquifers were estimated based on results of the EM flowmeter survey and a 72-hour aquifer test completed in Lower Floridan aquifer well 36Q398. The EM flowmeter data were analyzed using an AnalyzeHOLE-generated model to simulate upward borehole flow and determine the transmissivity of water-bearing zones. Aquifer-test data were analyzed with a two-dimensional, axisymmetric, radial, transient, groundwater-flow model using MODFLOW–2005. The flowmeter-survey and aquifer-test simulations provided an estimated transmissivity of about 60,000 square feet per day for the Upper Floridan aquifer and about 5,000 square feet per day for the Lower Floridan aquifer.Water in discrete-depth samples collected from the Upper Floridan aquifer, middle semiconfining unit, and Lower Floridan aquifer during the EM flowmeter survey in August 2013 was low in dissolved solids. Tested constituents were in concentrations within established U.S. Environmental Protection Agency drinking water-quality criteria. Concentrations of measured constituents in water samples from Lower Floridan aquifer well 36Q398 collected at the end of the 72-hour aquifer test in November 2013 were generally higher than in the discrete-depth samples collected during EM flowmeter testing in August 2013 but remained within established drinking water-quality criteria.Water-level data for the aquifer test were filtered for external influences such as barometric pressure, earth-tide effects, and long-term trends to enable detection of small (less than 1 ft) water-level responses to aquifer-test withdrawal. During the 72-hour aquifer test, the Lower Floridan aquifer was pumped at a rate of 750 gallons per minute resulting in a drawdown response of 35.5 ft in the pumped well; 1.6 ft in the Lower Floridan aquifer observation well located about 6,000 ft west of the pumped well; and responses of 0.7, 0.6, and 0.4 ft in the Upper Floridan aquifer observation wells located about 36 ft, 6,000 ft, and 6,800 ft from the pumped well, respectively

Inactivation and removal of influenza A virus H1N1 during the manufacture of plasma derivatives.

2010-11-01

Although transmission of pandemic influenza A virus H1N1 2009 is still occurring globally, little has been reported about how this outbreak has affected the safety of plasma derivatives. To evaluate the safety of plasma derivatives, dedicated virus clearance processes used during their production were investigated for their effectiveness in eliminating this virus of recent concern. In this study, influenza A virus H1N1 strain A/NWS/33 (H1N1) was chosen as a surrogate. H1N1 was completely inactivated by fraction IV fractionation as well as pasteurization during the manufacture of albumin. H1N1 was also effectively removed into the precipitate by fraction III fractionation and completely inactivated by low pH incubation as well as pasteurization during the manufacture of intravenous immunoglobulin. H1N1 was completely inactivated within 1 min of solvent/detergent treatment using 0.3% tri (n-butyl) phosphate and 1.0% Triton X-100 and also completely inactivated within 10 min of dry-heat treatment at 98 °C during the manufacture of factor VIII. H1N1 was completely removed by virus filtration process using Viresolve NFP filter and also completely inactivated by pasteurization during the manufacture of anti-thrombin III. These results indicate that all the virus clearance processes commonly used have sufficient H1N1 reducing capacity to achieve a high margin of safety.

Potentiometric surfaces of aquifers in the Cockfield Formation in southeastern Arkansas and the Wilcox Group in southern and northeastern Arkansas, 2000

USGS Publications Warehouse

Schrader, Tony P.; Joseph, Robert L.

2000-01-01

The Cockfield and lower Wilcox aquifers are sources of water for local use in southern and northeastern Arkansas, where in 1995 more than 51 million gallons per day of water was withdrawn. During January through April 2000, 54 water-level measurements were made in wells completed in the Cockfield aquifer, 13 water-level measurements were made in wells completed in the lower Wilcox aquifer in southern Arkansas, and 43 water-level measurements were made in wells completed in the lower Wilcox aquifer in northeastern Arkansas. The potentiometric surface data reveal spatial trends in both aquifers across the study areas. The regional direction of ground-water flow of the Cockfield aquifer is generally toward the east and south, away from the outcrop area, except in areas of intense ground-water withdrawals. The configuration of the potentiometric surface indicates that heavy pumpage has probably altered or reversed the natural direction of flow in these areas. A potentiometric low caused by the pumpage near Greenville, Mississippi, extends into Chicot, Desha, and Drew Counties. Water levels in five wells showed average declines between 0.5 and 0.8 foot per year. The regional direction of ground-water flow in the lower Wilcox aquifers is generally east and south, away from the outcrop, except in areas of intense ground-water withdrawals. Potentiometric depressions, where flow is toward centers of pumping, indicate that heavy pumpage has probably altered or reversed the natural direction of flow. Two potentiometric depressions are centered in the vicinity of Paragould and West Memphis, Arkansas, where ground-water withdrawals probably have altered the natural direction of flow. Long-term hydrographs of seven wells show water-level declines in the lower Wilcox aquifer in northeastern Arkansas. The average water-level decline in two wells was between 0.8 and 1.0 foot per year and in five wells was between 1.2 and 1.8 foot per year.

Completion Report for Model Evaluation Well ER-5-5: Corrective Action Unit 98: Frenchman Flat

2013-01-18

Model Evaluation Well ER-5-5 was drilled for the U.S. Department of Energy, National Nuclear Security Administration Nevada Site Office in support of Nevada Environmental Management Operations at the Nevada National Security Site (formerly known as the Nevada Test Site). The well was drilled in July and August 2012 as part of a model evaluation well program in the Frenchman Flat area of Nye County, Nevada. The primary purpose of the well was to provide detailed geologic, hydrogeologic, chemical, and radiological data that can be used to test and build confidence in the applicability of the Frenchman Flat Corrective Action Unitmore » flow and transport models for their intended purpose. In particular, this well was designed to obtain data to evaluate the uncertainty in model forecasts of contaminant migration from the upgradient underground nuclear test MILK SHAKE, conducted in Emplacement Hole U-5k in 1968, which were considered to be uncertain due to the unknown extent of a basalt lava-flow aquifer present in this area. Well ER-5-5 is expected to provide information to refine the Phase II Frenchman Flat hydrostratigraphic framework model, if necessary, as well as to support future groundwater flow and transport modeling. The 31.1-centimeter (cm) diameter hole was drilled to a total depth of 331.3 meters (m). The completion string, set at the depth of 317.2 m, consists of 16.8-cm stainless-steel casing hanging from 19.4-cm carbon-steel casing. The 16.8-cm stainless-steel casing has one slotted interval open to the basalt lava-flow aquifer and limited intervals of the overlying and underlying alluvial aquifer. A piezometer string was also installed in the annulus between the completion string and the borehole wall. The piezometer is composed of 7.3-cm stainless-steel tubing suspended from 6.0-cm carbon-steel tubing. The piezometer string was landed at 319.2 m, to monitor the basalt lava-flow aquifer. Data collected during and shortly after hole construction include composite drill cuttings samples collected every 3.0 m, various geophysical logs, preliminary water quality measurements, and water-level measurements. The well penetrated 331.3 m of Quaternary–Tertiary alluvium, including an intercalated layer of saturated basalt lava rubble. No well development or hydrologic testing was conducted in this well immediately after completion; however, a preliminary water level was measured in the piezometer string at the depth of 283.4 m on September 25, 2012. No tritium above the minimum detection limit of the field instruments was detected in this hole. Future well development, sampling, and hydrologic testing planned for this well will provide more accurate hydrologic information for this site. The stratigraphy, general lithology, and water level were as expected, though the expected basalt lava-flow aquifer is basalt rubble and not the dense, fractured lava as modeled. The lack of tritium transport is likely due to the difference in hydraulic properties of the basalt lava-flow rubble encountered in the well, compared to those of the fractured aquifer used in the flow and transport models.« less

Construction and validation of a measure of integrative well-being in seven languages: the Pemberton Happiness Index.

PubMed

Hervás, Gonzalo; Vázquez, Carmelo

2013-04-22

We introduce the Pemberton Happiness Index (PHI), a new integrative measure of well-being in seven languages, detailing the validation process and presenting psychometric data. The scale includes eleven items related to different domains of remembered well-being (general, hedonic, eudaimonic, and social well-being) and ten items related to experienced well-being (i.e., positive and negative emotional events that possibly happened the day before); the sum of these items produces a combined well-being index. A distinctive characteristic of this study is that to construct the scale, an initial pool of items, covering the remembered and experienced well-being domains, were subjected to a complete selection and validation process. These items were based on widely used scales (e.g., PANAS, Satisfaction With Life Scale, Subjective Happiness Scale, and Psychological Well-Being Scales). Both the initial items and reference scales were translated into seven languages and completed via Internet by participants (N = 4,052) aged 16 to 60 years from nine countries (Germany, India, Japan, Mexico, Russia, Spain, Sweden, Turkey, and USA). Results from this initial validation study provided very good support for the psychometric properties of the PHI (i.e., internal consistency, a single-factor structure, and convergent and incremental validity). Given the PHI's good psychometric properties, this simple and integrative index could be used as an instrument to monitor changes in well-being. We discuss the utility of this integrative index to explore well-being in individuals and communities.

Gary, Anthony T; Kerl, Marie E; Wiedmeyer, Charles E; Turnquist, Susan E; Cohn, Leah A

2004-01-01

A 1.5-year-old Doberman pinscher was presented with sudden-onset of fever and malaise. Twelve days prior to presentation, fenbendazole therapy was initiated for a suspected lungworm infection. Results of a complete blood count on presentation showed pancytopenia, while histopathological evaluation of a bone marrow core sample revealed bone marrow hypoplasia of undetermined etiology. Bactericidal antibiotics and fluid therapy, as well as discontinuation of fenbendazole administration, led to a complete resolution of clinical and hematological abnormalities within 15 days. An idiosyncratic reaction to fenbendazole was suspected based on the absence of infectious, neoplastic, autoimmune, and toxic etiologies, as well as resolution of clinical signs and pancytopenia upon drug withdrawal.

Oil and Gas Data Infrastructure Project: Project Accomplishments Summary CRADA No. TO-1111-95

Wagoner, Jeff; Paul, Robert; Chesser, Joe

2000-11-14

Obtaining a substantially complete set of the relevant data for an oil or gas producing property is a very time-consuming and nearly impossible task which limits the producer's effectiveness in making sound business and engineering decisions. The data are located in a variety of places, some of which are completely inaccessible to the average user. Access to information on existing wells is a crucial component of a producer's ability to assess the feasibility of purchasing and operating a well. The more effective the access the producer has to the information, the greater the likelihood that a wider suite of choicesmore » can be considered and a profitable business decision reached. California, like a number of other states, provides public access to oil and gas production data, and other types of supplemental well information. However, access mechanisms are often ineffective, tedious, and expensive to maintain as much of the data is centrally located and in a format that is difficult to search, retrieve, and refile. The California Division of Oil and Gas and Geothermal Resources (CADOGGR) regulates California's oil and gas drilling and production operations. The CADOGGR administers the state laws for the conservation of oil and gas resources to prevent damage to life, health, property, and natural resources. The principal mandated objectives in regulating oil and gas exploratory, development, and production operations are to prevent conditions that may be hazardous to health or damaging to the environment. As part of the regulatory program, well records are maintained on each well. There is information for each well consisting of applications to do work, permits issued, drilling and exploration histories, geophysical logs, production data, maps, reports, test results, well logs, abandonment and other types of information which the producers are required to provide to the states on an on-going basis. These well records are also considered vital to the industry because they are the only complete source of public information needed for continued exploration and development work. Making copies of the well records available to the industry and the public is an important function.« less

Contamination of wells completed in the Roubidoux aquifer by abandoned zinc and lead mines, Ottawa County, Oklahoma

USGS Publications Warehouse

Christenson, Scott C.

1995-01-01

The Roubidoux aquifer in Ottawa County Oklahoma is used extensively as a source of water for public supplies, commerce, industry, and rural water districts. Water in the Roubidoux aquifer in eastern Ottawa County has relatively low dissolved-solids concentrations (less than 200 mg/L) with calcium, magnesium, and bicarbonate as the major ions. The Boone Formation is stratigraphically above the Roubidoux aquifer and is the host rock for zinc and lead sulfide ores, with the richest deposits located in the vicinity of the City of Picher. Mining in what became known as the Picher mining district began in the early 1900's and continued until about 1970. The water in the abandoned zinc and lead mines contains high concentrations of calcium, magnesium, bicarbonate, sulfate, fluoride, cadmium, copper, iron, lead, manganese, nickel, and zinc. Water from the abandoned mines is a potential source of contamination to the Roubidoux aquifer and to wells completed in the Roubidoux aquifer. Water samples were collected from wells completed in the Roubidoux aquifer in the Picher mining district and from wells outside the mining district to determine if 10 public supply wells in the mining district are contaminated. The chemical analyses indicate that at least 7 of the 10 public supply wells in the Picher mining district are contaminated by mine water. Application of the Mann-Whitney test indicated that the concentrations of some chemical constituents that are indicators of mine-water contamination are different in water samples from wells in the mining area as compared to wells outside the mining area. Application of the Wilcoxon signed-rank test showed that the concentrations of some chemical constituents that are indicators of mine-water contamination were higher in current (1992-93) data than in historic (1981-83) data, except for pH, which was lower in current than in historic data. pH and sulfate, alkalinity, bicarbonate, magnesium, iron, and tritium concentrations consistently indicate that the Cardin, Commerce 1, Commerce 3, Picher 2, Picher 3, Picher 4, and Quapaw 2 wells are contaminated.

This study assessed the antecedents of continued use of an education program to prevent passive smoking in infants. It consists of a booklet for parents and a manual for health professionals describing a five-step procedure for discussing passive smoking. A questionnaire was sent to 67 managers, 670 nurses, and 335 physicians working in well-baby clinics (response rate: 70%, 53%, 47% respectively). Questions concerned the completeness of use, level of institutionalization, and characteristics of the organization, the user, and the dissemination strategy. Seventy-one percent of nurses and 42% of physicians worked with the program. They foremost provided the first three steps of the five-step procedure. Physicians' completeness of use was related to their perceived responsibility in providing this education, and nurses' use was related to their perceived self-efficacy, responsibility, training attendance, participation in the adoption decision, and level of institutionalization. Diffusion efforts should focus on improving the completeness of use and level of institutionalization.

Well construction, lithology, and geophysical logs for boreholes in Bear Creek Valley near Oak Ridge, Tennessee

USGS Publications Warehouse

Bailey, Z.C.; Hanchar, D.W.

1988-01-01

Twenty-four wells were constructed at nine sites at Bear Creek Valley to provide geologic and hydrologic information. Lithologic samples and suits of geophysical logs were obtained from the deepest boreholes at six of the sites. Two of these boreholes at the base of Chestnut Ridge were completed in the Maynardville Limestone and two were completed in the Nolichucky Shale. Two boreholes along Pine Ridge were completed in the Rome Formation. Zones of similar lithology within a borehole were delineated from rock cutting refined by examination of geophysical logs. The contact between the Maynardville Limestone and Nolichucky Shale was identified in two of the boreholes. Fractures and cavities were readily identifiable on the acoustic-televiewer and caliper logs. Distinct water-bearing intervals were also identified from the temperature, fluid resistance, and resistivity logs. Depths at which the drilling encounterd a thrust were identified in two boreholes in the Rome Formation from both rock cutting and geophysical logs. (USGS)

2015-10-01

Exercise-induced bronchoconstriction (EIB) has not been well studied in cystic fibrosis (CF), and eucapnic voluntary hyperventilation (EVH) testing has not been used as an objective assessment of EIB in CF to date. A prospective cohort pilot study was completed where standard EVH testing was completed by 10 CF patients with forced expiratory volume in 1 s (FEV1) ≥70% of predicted. All patients also completed a cardiopulmonary exercise test (CPET) with pre- and post-CPET spirometry as a comparative method of detecting EIB. No adverse events occurred with EVH testing. A total of 20% (2/10) patients were diagnosed with EIB by means of EVH. Both patients had clinical symptoms consistent with EIB. No patient had a CPET-based exercise challenge consistent with EIB. EVH testing was safe and effective in the objective assessment for EIB in patients with CF who had well-preserved lung function. It may be a more sensitive method of detecting EIB then exercise challenge.

Pedernales oilfield, eastern Venezuela: The first 100 years

DOE Office of Scientific and Technical Information (OSTI.GOV)

Gluyas, J.; Oliver, J.; Wilson, W.

1996-08-01

Petroleum seeps and surface tar mats attracted oil explorers to Pedernales in eastern Venezuela 100 years ago. Commercial production from the Pedernales Field was established by Creole in 1933. In three production periods, broken by WWII and the end of the Creole-Texaco refining contract, Creole and Lagoven produced about 60 MMSTB from about 60 wells in about 60 years. Peak production was in the late 1950s, when the field delivered 12,000 BOPD. Production was stopped in 1986. In March 1993, BP Venezuela acquired the license to reactivate Pedernales on behalf of Lagoven, and BP`s first well in the field wasmore » drilled in August 1994. A second was completed in early 1995. The production from each well was sufficiently encouraging for commerciality to be declared in March 1995. Phase 1 of the field reactivation demanded a production rate of 11,500 BOPD. As of now (September, 1995) six wells, including one gas disposal well, have been completed. Wells have been placed using a combination of old well data and mapping based on a close spaced 2D seismic survey shot in early 1994. Results from these first few wells indicate that the required production rate will be achieved despite severely depleted reservoir pressures. This paper tells the story of reactivation and re-evaluation of one of eastern Venezuela`s oldest oilfields.« less

Steam flooding from mine workings, a viable alternative

DOE Office of Scientific and Technical Information (OSTI.GOV)

Ayler, M.F.; Brechtel, C.

1987-05-01

The advent of steam flooding has given new life to several fields in California, substantially increasing the recoverable reserve. This process can be combined with a newly developed concept combining petroleum and mining technology. By placing mine workings 100 ft, more or less, below the bottom of the reservoir, it is possible to safely drill wells upward through the reservoir and complete them in such a way that all produced cuttings and fluids are contained within closed pipelines. Each completed well could serve as a steam injection well with continuous gravity-produced oil from the same well. As all fluids wouldmore » flow by gravity to a collection pipeline, the only needed pumps would be at the discharge within the mine shaft. Mine shafts serving the oil field could be placed in environmentally optimum sites roughly one mile apart, eliminating many of the visually objectionable disturbances. Production wells could be placed on one acre or even closer spacing, whatever good engineering dictates. Automatic controls can continuously monitor and control production from each well. Assuming one-acre well spacing, continuous steam flooding, and production from each well, a detailed analysis of anticipated mining costs indicate oil production costs under $5/bbl are possible. Even at $10/BO, a positive cash flow within two years after the start of shaft sinking is expected.« less

Trends in Methyl tert-Butyl Ether Concentrations in Private Wells in Southeast New Hampshire: 2005 to 2015.

Flanagan, Sarah M; Levitt, Joseph P; Ayotte, Joseph D

2017-02-07

In southeast New Hampshire, where reformulated gasoline was used from the 1990s to 2007, methyl tert-butyl ether (MtBE) concentrations ≥0.2 μg/L were found in water from 26.7% of 195 domestic wells sampled in 2005. Ten years later in 2015, and eight years after MtBE was banned, 10.3% continue to have MtBE. Most wells (140 of 195) had no MtBE detections (concentrations <0.2 μg/L) in 2005 and 2015. Of the remaining wells, MtBE concentrations increased in 4 wells, decreased in 47 wells, and did not change in 4 wells. On average, MtBE concentrations decreased 65% among 47 wells whereas MtBE concentrations increased 17% among 4 wells between 2005 and 2015. The percent change in detection frequency from 2005 to 2015 (the decontamination rate) was lowest (45.5%) in high-population-density areas and in wells completed in the Berwick Formation geologic units. The decontamination rate was the highest (78.6%) where population densities were low and wells were completed in bedrock composed of granite, metamorphic, and mafic rocks. Wells in the Berwick Formation are characteristically deeper and have lower yields than wells in other rock types and have shallower overburden cover, which may allow for more rapid transport of MtBE from land-surface releases. Low-yielding, deep bedrock wells may require large contributing areas to achieve adequate well yield, and thus have a greater chance of intercepting MtBE, in addition to diluting contaminants at a slower rate and thus requiring more time to decontaminate.

It is well-known that parental stress and coping impacts the well-being of children with serious illness. The current study aimed to evaluate the feasibility and satisfaction of a novel resilience promoting intervention, the Promoting Resilience in Stress Management Intervention for Parents (PRISM-P) among parents of adolescents and young adults with Type 1 diabetes or cancer. Secondary analyses explored the effect of the PRISM-P on parent-reported resilience and distress. The PRISM-P includes 4 short skills-based modules, delivered in either 2 or 4 separate, individual sessions. English-speaking parents of adolescents with cancer or Type 1 diabetes were eligible. Feasibility was conservatively defined as a completion rate of 80%; satisfaction was qualitatively evaluated based upon parent feedback regarding intervention content, timing, and format. Resilience and distress were assessed pre- and postintervention with the Connor Davidson Resilience Scale and the Kessler-6 Psychological Distress Scale. Twelve of 24 caregivers of youth with diabetes (50%) and 13 of 15 caregivers of youth with cancer (87%) agreed to participate. Nine of 12 (75%) and 9 of 13 (64%) completed all PRISM-P modules, respectively. Among those who completed the intervention, qualitative satisfaction was high. Parent-reported resilience and distress scores improved after the intervention. Effect sizes for both groups indicated a moderate intervention effect. Ultimately, the PRISM-P intervention was well accepted and impactful among parents who completed it. However, attrition rates were higher than anticipated, suggesting alternative or less time-intensive formats may be more feasible. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

2018-03-01

Patient adherence has been identified as an important barrier to the implementation of evidence-based psychological treatments. In cognitive behavioral treatments (CBT) for insomnia, the current study examined (a) the validity of therapist ratings of patient agreement and adherence against an established behavioral measure of adherence, and (b) the relationship between treatment agreement, adherence, and outcome. Participants were 188 adults meeting DSM-IV-TR criteria for chronic insomnia who were randomized to receive behavior therapy, cognitive therapy, or CBT for insomnia. Treatment agreement/adherence was measured by (a) weekly therapist ratings of patient agreement and homework completion, and (b) adherence to behavioral strategies (ABS) derived from patient-reported sleep diary. Outcome measures were Insomnia Severity Index and insomnia remission (Insomnia Severity Index <8). Therapist ratings of patient agreement as well as homework completion were significantly associated with sleep diary-derived global ABS. Therapist-rated patient agreement and homework completion as well as global ABS predicted greater insomnia symptoms reduction from pretreatment to posttreatment. Patient agreement also predicted insomnia symptoms reduction from pretreatment to 6-month follow-up. Patient agreement, adherence, and ABS measures during treatment significantly predicted insomnia remission at posttreatment, and all but therapist rating of homework completion predicted remission at 6-month follow-up. Greater patient agreement and adherence (therapist ratings and ABS) during treatment predicted better treatment outcome. Therapist-rated treatment agreement and adherence correspond well with patient-reported sleep diary-derived adherence measure. These simple, deployable therapist-rated patient agreement and adherence can potentially be useful for treatments for other disorders. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

The aim of the paper is to describe the formative evaluation of the feedback component of an online nutrition tailoring instrument, the Children's and Adolescents' Nutrition Assessment and Advice on the Web (CANAA-W), among parents of schoolchildren. Parents of pre-primary and primary-school children recorded their child's food intake over 3 d with CANAA-W and completed the evaluation questionnaire online. A subsample participated in focus group discussions. Parents completed CANAA-W at home. Forty-six parents completed the evaluation questionnaire. Seventeen parents participated in three focus group discussions. Parents were enthusiastic: the majority (81 % or more) found the advice comprehensible, interesting, logical, useful, believable, well formulated, correct, personal, relevant, complete, attractive, containing enough and not too much information; they indicated that it is helpful to improve their children's eating habits and that they intend to use it. The qualitative analyses revealed that the respondents appreciated the confrontation with their child's diet and the visualization (i.e. traffic light colours, pictograms, food models, diagrams). The length of the feedback was rather a drawback, but it was useful nevertheless. CANAA-W was well received by the parents; the scores on the feasibility questionnaire were high and the qualitative analyses showed that the confrontation with their child's diet, and attractive visualization of the most relevant feedback linked to more elaborated optional feedback, were well appreciated. The major challenge will be to convince parents who are less interested in food habits and less computer-literate to participate in this type of study.

Application of the Extended Completeness Relation to the Absorbing Boundary Condition

Iwasaki, Masataka; Otani, Reiji; Ito, Makoto

The strength function of the linear response by the external field is calculated in the formalism of the absorbing boundary condition (ABC). The dipole excitation of a schematic two-body system is treated in the present study. The extended completeness relation, which is assumed on the analogy of the formulation in the complex scaling method (CSM), is applied to the calculation of the strength function. The calculation of the strength function is successful in the present formalism and hence, the extended completeness relation seems to work well in the ABC formalism. The contributions from the resonance and the non-resonant continuum are also analyzed according to the decomposition of the energy levels in the extended completeness relation.

2016-01-01

Background Faunal change is a basic and fundamental element in ecology, biogeography, and conservation biology, yet vanishingly few detailed studies have documented such changes rigorously over decadal time scales. This study responds to that gap in knowledge, providing a detailed analysis of Digital Accessible Knowledge of the birds of Mexico, designed to marshal DAK to identify sites that were sampled and inventoried rigorously prior to the beginning of major global climate change (1980). Methods We accumulated DAK records for Mexican birds from all relevant online biodiversity data portals. After extensive cleaning steps, we calculated completeness indices for each 0.05° pixel across the country; we also detected ‘hotspots’ of sampling, and calculated completeness indices for these broader areas as well. Sites were designated as well-sampled if they had completeness indices above 80% and >200 associated DAK records. Results We identified 100 individual pixels and 20 broader ‘hotspots’ of sampling that were demonstrably well-inventoried prior to 1980. These sites are catalogued and documented to promote and enable resurvey efforts that can document events of avifaunal change (and non-change) across the country on decadal time scales. Conclusions Development of repeated surveys for many sites across Mexico, and particularly for sites for which historical surveys document their avifaunas prior to major climate change processes, would pay rich rewards in information about distributional dynamics of Mexican birds.

Since 1987, usage of measurement while drilling (MWD) technology within Esso Production Malaysia Inc. (EPMI) has evolved from an auxiliary directional drilling service to providing a reliable alternative to wireline logs for formation evaluation and well-completion purposes. The shift in EPMI's attitude toward the use of MWD in formation evaluation is attributed to the availability of a complete suite of logging services for the log analysis procedure, accuracy of the data, sufficient control in reservoir quality, and continuity in fields where there are already a high density of wireline-logged wells, increasing number of high angle and horizontal wells being drilled,more » a favorable track record, and realized economic benefits. The in-house analysis procedure, (EPMILOG[sup 6]), requires the availability of a deep and/or shallow investigating resistivity, formation density, neutron porosity, and gamma ray tools for a complete analysis. The availability of these services in MWD and also comparative evaluations of MWD responses with their correlative wireline counterparts show that MWD technology can be used, to a large extent, to complement or replace routine wireline logging services. MWD resistivity measurements are frequently observed to be less effected by mud filtrate invasion than the correlative wireline measurements and are, therefore, closer to the true resistivity of the formation. MWD formation evaluation services are most widely used in fields where there are already a high density of wells that were logged using wireline. The MWD data is used to decide perforation depths and intervals.« less

Sexual and reproductive health conditions (eg, infections, cancers) represent public health concerns for American women. The present study examined how knowledge of the Patient Protection and Affordable Care Act (PPACA) relates to receipt of preventive reproductive health services among women. Cross-sectional online survey. Online questionnaires were completed via Amazon Mechanical Turk, a crowdsourcing website where individuals complete web-based tasks for compensation. Cisgendered women aged 18 to 44 years (N = 1083) from across the United States. Participants completed online questionnaires assessing demographics, insurance status, preventive service use, and knowledge of PPACA provisions. Chi-squares showed that receipt of well-woman, pelvic, and breast examinations, as well as pap smears, was related to insurance coverage, with those not having coverage at all during the previous year having significantly lower rates of use. Hierarchical logistic regressions determined the independent relationship between PPACA knowledge and use of health services after controlling for demographic factors and insurance status. Knowledge of PPACA provisions was associated with receiving well-woman, pelvic, and breast examinations, human papillomavirus vaccination, and sexually transmitted infections testing, after controlling for these factors. Results indicate that expanding knowledge about health-care legislation may be beneficial in increasing preventive reproductive health service use among women. Current findings provide support for increasing resources for outreach and education of the general population about the provisions and benefits of health-care legislation, as well as personal health coverage plans.

The U.S. Geological Survey (USGS) collects ground-water data and conducts studies to monitor hydrologic conditions, to better define ground-water resources, and address problems related to water supply and water quality. Data collected as part of ground-water studies include geologic, geophysical, hydraulic property, water level, and water quality. A ground-water-level network has been established throughout most of the State of Georgia, and ground-water-quality networks have been established in the cities of Albany, Savannah, and Brunswick and in Camden County, Georgia. Ground-water levels are monitored continuously in a network of wells completed in major aquifers of the State. This network includes 17 wells in the surficial aquifer, 12 wells in the upper and lower Brunswick aquifers, 73 wells in the Upper Floridan aquifer, 10 wells in the Lower Floridan aquifer and underlying units, 12 wells in the Claiborne aquifer, 1 well in the Gordon aquifer, 11 wells in the Clayton aquifer, 11 wells in the Cretaceous aquifer system, 2 wells in Paleozoic-rock aquifers, and 7 wells in crystalline-rock aquifers. In this report, data from these 156 wells were evaluated to determine whether mean-annual ground-water levels were within, below, or above the normal range during 2001, based on summary statistics for the period of record. Information from these summaries indicates that water levels during 2001 were below normal in almost all aquifers monitored, largely reflecting climatic effects from drought and pumping. In addition, water-level hydrographs for selected wells indicate that water levels have declined during the past 5 years (since 1997) in almost all aquifers monitored, with water levels in some wells falling below historical lows. In addition to continuous water-level data, periodic measurements taken in 52 wells in the Camden County-Charlton County area, and 65 wells in the city of Albany-Dougherty County area were used to construct potentiometric-surface maps for the Upper Floridan aquifer. Ground-water quality in the Upper Floridan aquifer is monitored in the cities of Albany, Savannah, and Brunswick and in Camden County; and monitored in the Lower Floridan aquifer in the Savannah and Brunswick areas. In the Albany area since 1998, nitrate concentrations in the Upper Floridan aquifer have increased in 4 of the 11 wells monitored, and in 1 well, concentrations were above the U.S. Environmental Protection Agency's (USEPA) 10 milligrams per liter (mg/L) drinking-water standard. In the Savannah area, chloride concentration in water from four wells in the Upper Floridan aquifer showed no appreciable change during 2001, remaining within the USEPA 250 mg/L drinking-water standard; in seven wells completed in the Lower Floridan aquifer and in underlying zones, the chloride concentration remained above the drinking-water standard, with one well showing an increase over previous years. In the Brunswick area, water samples from 66 wells completed in the Upper or Lower Floridan aquifers were collected during June 2001 and analyzed for chloride. A map showing chloride concentrations in the Upper Floridan aquifer during June 2001 indicates that concentrations remained above USEPA drinking-water standards across a 2-square-mile area. In the north Brunswick area, chloride concentrations in the Upper Floridan aquifer continued to increase, whereas in the south Brunswick area, concentrations continued to decrease. In the Camden County area, chloride concentrations in six wells completed in the Upper Floridan aquifer remained within drinking-water standards. With the exception of one well, concentrations remained the same and were below 40 mg/L. In one well, concentrations showed a sharp decline during 2001, but remained above 130 mg/L. Ongoing studies during 2001 include evaluation of agricultural chemicals in shallow ground water in southwestern Georgia; evaluation of saltwater intrusion and water-level and water-quality m

Reference or standard atmospheric models have long been used for design and mission planning of various aerospace systems. The NASA Marshall Space Flight Center Global Reference Atmospheric Model was developed in response to the need for a design reference atmosphere that provides complete global geographical variability and complete altitude coverage (surface to orbital altitudes), as well as complete seasonal and monthly variability of the thermodynamic variables and wind components. In addition to providing the geographical, height, and monthly variation of the mean atmospheric state, it includes the ability to simulate spatial and temporal perturbations.

The Gnome-Coach, New Mexico, Site was the location of a 3-kiloton-yield underground nuclear test in 1961 and a groundwater tracer test in 1963. The U.S. Geological Survey conducted the groundwater tracer test using four dissolved radionuclides--tritium, iodine-131, strontium-90, and cesium-137--as tracers. Site reclamation and remediation began after the underground testing, and was conducted in several phases at the site. The New Mexico Environment Department (NMED) issued a Conditional Certificate of Completion in September 2014, which documents that surface remediation activities have been successfully completed in accordance with the Voluntary Remediation Program. Subsurface activities have included annual sampling and monitoring ofmore » wells at and near the site since 1972. These annual monitoring activities were enhanced in 2008 to include monitoring hydraulic head and collecting samples from the onsite wells USGS-4, USGS-8, and LRL-7 using the low-flow sampling method. In 2010, the annual monitoring was focused to the monitoring wells within the site boundary. A site inspection and annual sampling were conducted on January 27-28, 2015. A second site visit was conducted on April 21, 2015, to install warning/notification signs to fulfill a requirement of the Conditional Certificate of Completion that was issued by the NMED for the surface.« less

Spatial perception changes associated with space flight: implications for adaptation to altered inertial environments.

PubMed

Parker, Donald E

2003-01-01

Preparation for extended travel by astronauts within the Solar System, including a possible manned mission to Mars, requires more complete understanding of adaptation to altered inertial environments. Improved understanding is needed to support development and evaluation of interventions to facilitate adaptations during transitions between those environments. Travel to another planet escalates the adaptive challenge because astronauts will experience prolonged exposure to microgravity before encountering a novel gravitational environment. This challenge would have to be met without ground support at the landing site. Evaluation of current adaptive status as well as intervention efficacy can be performed using perceptual, eye movement and postural measures. Due to discrepancies of adaptation magnitude and time-course among these measures, complete understanding of adaptation processes, as well as intervention evaluation, requires examination of all three. Previous research and theory that provide models for comprehending adaptation to altered inertial environments are briefly examined. Reports from astronauts of selected pre- in- and postflight self-motion illusions are described. The currently controversial tilt-translation reinterpretation hypothesis is reviewed and possible resolutions to the controversy are proposed. Finally, based on apparent gaps in our current knowledge, further research is proposed to achieve a more complete understanding of adaptation as well as to develop effective counter-measures.

While the link between educational attainment and future health and wellness is well understood, little investigation has considered the potential impacts of distinct forms of childhood maltreatment on high school completion. In the present study, the relationship between five categories of childhood maltreatment (physical, emotional, and sexual abuse, and physical and emotional neglect) and completion of high school education were examined using the Childhood Trauma Questionnaire (CTQ). From September 2005 to May 2013, data were collected for the At-Risk Youth Study (ARYS), a cohort of street-involved young people who use illicit drugs in Vancouver, Canada. We used logistic regression to examine the relationship between childhood maltreatment and high school completion, while controlling for a range of potential confounding variables. Specifically, five separate models for each category of maltreatment and two combined models were employed to examine the relative associations between, and cumulative impact of, different forms of childhood maltreatment and educational attainment. Among 974 young people, 737 (76%) reported not completing high school. In separate multivariable analyses physical abuse, emotional abuse, physical neglect, and emotional neglect remained positively and independently associated with an incomplete high school education. In a combined multivariable model with all forms of childhood maltreatment considered together, emotional abuse (adjusted odds ratio = 2.08; 95% confidence interval: 1.51-2.86) was the only form of maltreatment that remained significantly associated with an incomplete high school education. The cumulative impact assessment indicated a moderate dose-dependent trend where the greater the number of different forms of childhood maltreatment the greater the risk of not completing a high school education. These findings point to the need for trauma-informed interventions to improve educational attainment among vulnerable young people, as well as evidence-based prevention programmes, such as the Nurse-Family Partnership, aimed at supporting at-risk families before maltreatment occurs. © 2015 John Wiley & Sons Ltd.

Background: The Breast Implant Follow-up Study is a large, ongoing observational study of women who received Natrelle round silicone-filled or saline-filled breast implants. This analysis describes patient-reported outcomes in the cohort who underwent breast augmentation. Methods: Subjects prospectively completed two validated scales of the BREAST-Q (satisfaction with breasts and psychosocial well-being) preoperatively and at 1 and 4 years postoperatively. Effect size and z tests were used to compare differences between preoperative versus postoperative scores; multivariate mixed models were used to compare differences in scores between silicone-filled and saline-filled implants. Results: Of 17,899 subjects completing the BREAST-Q preoperatively, 14,514 (81.1 percent) completed the postoperative questionnaire (12,726 received silicone-filled implants and 1788 received saline-filled implants). Overall, satisfaction with breasts and psychosocial well-being increased significantly at postoperative year 1 (p < 0.0001 for both), and the improvement was sustained at year 4 (p < 0.0001 for both). Large effect sizes were observed for satisfaction with breasts (2.0 at year 1; 1.8 at year 4) and psychosocial well-being (1.2 at year 1; 1.0 at year 4). In the multivariate model, silicone-filled implants were associated with significantly greater improvement compared with saline-filled implants for satisfaction with breasts and psychosocial well-being at year 1 (p < 0.0001 for both) and year 4 (p < 0.0001 and p < 0.0019, respectively). Conclusions: Breast implants are effective in improving women’s quality of life. The authors found significant and sustained improvements in satisfaction and psychosocial well-being in women undergoing breast augmentation with Natrelle silicone-filled or saline-filled implants.

Development of geothermal resources in southwest Utah's Sevier thermal area continued in the early 1990s with expansion of existing power-generation facilities. Completion of the Bud L. Bonnett geothermal power plant at the Cove Fort-Sulphurdale geothermal area brought total power generation capacity of the facility to 13.5 MWe (gross). At Cove Fort-Sulphurdate, recent declines in steam pressures within the shallow, vapor-dominated part of the resource prompted field developers to complete additional geothermal supply wells into the deeper, liquid-dominated portion of the resource. At Roosevelt Hot Springs near Milford, Intermountain Geothermal Company completed an additional supply well for Utah Power and Light Company's single-flash, Blundell plant. with the increased geothermal fluid supply from the new well, the Blundell plant now produces about 26 MWe (gross). The authors conducted several geothermal resource studies in undeveloped thermal areas in southwest Utah. Previous studies at Newcastle revealed a well-defined, self-potential minimum coincident with the intersection of major faults and the center of the heatflow anomaly. A detailed self-potential survey at Wood's Ranch, an area in northwest Iron County where thermal water was encountered in shallow wells, revealed a large (5,900 ?? 2,950 feet [1,800 ?? 900 m]) northeast-oriented self-potential anomaly which possibly results from the flow of shallow thermal fluid. Chemical geothermometry applied to Wood's Ranch water samples suggest reservoir temperatures between 230 and 248??F (110 and 120??C). At the Thermo Hot Springs geothermal area near Minersville, detailed self-potential surveys have also revealed an interesting 100 mV negative anomaly possibly related to the upward flow of hydrothermal fluid.

BACKGROUND North Carolina has the third largest community college system in the nation and reaches residents in all 100 counties. Few studies have focused on the health of employees who work at these institutions. We assessed the current status of and interest in supporting health promotion efforts among North Carolina Community College System members. METHODS North Carolina Community College System presidents completed a brief 15-item survey assessing support for and interest in offering health promotion programs. Wellness coordinators completed a 60-item questionnaire assessing current health promotion programming and organizational, environmental, and policy supports for health promotion efforts. Onsite interviews with a sub-sample of Wellness coordinators offered insights into important implementation considerations. We examined differences by campus size with Fisher's exact test. RESULTS All 58 presidents (100%) and 51 wellness coordinators (88%) completed surveys. Ten percent of colleges offered comprehensive employee health promotion programming. Most offered physical activity (70.6%), tobacco cessation (51.0%), weight loss/management (49.0%), and/or nutrition counseling (47.1%). Larger colleges were more likely to offer programming and environmental support. Nearly all presidents (89.7%) believed it is "very" or "extremely" important to offer health promotion programs to employees, and most (84%) were interested in promoting health through a university partnership. LIMITATIONS Despite very high survey response rates from presidents and wellness coordinators at each community college, onsite interviews were only done at select campuses, limiting the generalizability and scope of conclusions derived from interview data. CONCLUSION Community colleges in North Carolina are promising settings for promoting employee health. Findings identify resources, barriers, and technical assistance that could facilitate greater adoption and implementation of programs. ©2017 by the North Carolina Institute of Medicine and The Duke Endowment.

Monitoring for the migration of contaminants in groundwater or for the proper design of nuclear test emplacement holes at the Nevada Test Site (NTS) requires proper placement and completion of monitoring wells. This is only possible if the hydrogeologic system is understood in a regional and local context, necessitating data from existing wells and boreholes. Though the NTS Groundwater Characterization Project will be drilling wells, their great expense limits the number of new wells. However, there are many existing boreholes and wells on the NTS which have not been completely evaluated hydrologically. Some of these are incorporated in the Longmore » Term Hydrologic Monitoring Program (LTHMP) of the US Environmental Protection Agency (EPA), others are related to the testing programs. In all cases, additional site investigation in necessary to properly interpret the hydrogeologic data from these wells. Monitoring wells on the NTS are poorly characterized with regard to aquifers penetrated, vertical hydraulic gradients, and vertical variations in water quality. One of the goals of the well validation program was to gain a thorough understanding of the parameters needed to interpret the source and fate potential hazardous and radioactive substances that may be detected in these wells in the future. One of the most critical parameters for monitoring is the knowledge of what aquifer or geologic unit is being sampled when a water sample is collected. Pumped water samples are weighted most heavily to the water quality of the most productive (highest transmissivity) aquifer penetrated by the well.« less

Effects of seasonal operation on the quality of water produced by public-supply wells

Bexfield, Laura M.; Jurgens, Bryant C.

2014-01-01

Seasonal variability in groundwater pumping is common in many places, but resulting effects of seasonal pumping stress on the quality of water produced by public-supply wells are not thoroughly understood. Analysis of historical water-quality samples from public-supply wells completed in deep basin-fill aquifers in Modesto, California (134 wells) and Albuquerque, New Mexico (95 wells) indicates that several wells have seasonal variability in concentrations of contaminants of concern. In Modesto, supply wells are more likely to produce younger groundwater with higher nitrate and uranium concentrations during the summer (high) pumping season than during the winter (low) pumping season. In Albuquerque, supply wells are more likely to produce older groundwater with higher arsenic concentrations during the winter pumping season than during the summer pumping season. Seasonal variability in contaminant concentrations in Modesto is influenced primarily by effects of summer pumping on vertical hydraulic gradients that drive migration of shallow groundwater through the aquifer to supply wells. Variability in Albuquerque is influenced primarily by the period of time that a supply well is idle, allowing its wellbore to act as a conduit for vertical groundwater flow and contaminant migration. However, both processes are observed in each study area. Similar findings would appear to be likely in other alluvial basins with stratified water quality and substantial vertical head gradients. Results suggest that even in aquifers dominated by old groundwater, changes to seasonal pumping patterns and/or to depth of well completion can help reduce vulnerability to selected contaminants of either natural or anthropogenic origin.

Engagement in casual sex (or hooking up) is generally feared to have negative well-being consequences; however, empirical evidence is inconclusive, pointing toward potential moderators. Using self-determination theory (SDT), we hypothesized that well-being following hookups would depend on the type and level of motivation for hooking up. A university-wide sample of 528 undergraduates completed online surveys at the beginning (T1) and end (T3) of one academic year. After controlling for demographics, personality traits (i.e., neuroticism and extraversion), prior casual and romantic sex, and T1 well-being, having genital hookups between T1 and T3 for non-autonomous reasons (i.e., due to self-imposed pressures, external contingencies and controls, or complete lack of intentionality) was linked to lower self-esteem, higher depression and anxiety, and more physical symptoms. Autonomous hookup motivation (i.e., emanating from one's self) was not linked to any outcomes. Compared to peers without hookups, those with high non-autonomy in their hookups typically had inferior well-being; this was not true of those with low non-autonomy hookups. Gender differences, implications for SDT and casual sex research, and implications for educational programs and clinical work are discussed.

Boscan field is located in the western coast of Maracaibo lake and is operated by Maraven S.A., affiliate of Petroleos de Venezuela S.A. It has 315 active wells, 252 of which are produced with sucker rod pumping. Other artificial lift methods currently applied in this field are hydraulic (piston) pumping (39 wells) and ESP (24 wells). This paper presents the results of the production optimization of two sucker rod pumping wells of Boscan field producing viscous oil. This optimization has been possible due to the development of a new production scheme and the application of system analysis in completion design.more » The new production scheme involves the utilization of a subsurface stuffing box assembly and a slotted housing, both designed and patented by Intevep S.A., affiliate of Petroleos de Venezuela S.A. The completion design method and software used in the optimization study were also developed by Intevep S.A. The new production scheme and design method proved to be effective in preventing the causes of the above mentioned problems, allowing the increase of oil production under better operating conditions.« less

Total petroleum system assessment of undiscovered resources in the giant Barnett Shale continuous (unconventional) gas accumulation, Fort Worth Basin, Texas

Pollastro, R.M.

2007-01-01

Undiscovered natural gas having potential for additions to reserves in the Mississippian Barnett Shale of the Fort Worth Basin, north-central Texas, was assessed using the total petroleum system assessment unit concept and a cell-based methodology for continuous-type (Unconventional) resources. The Barnett-Paleozoic total petroleum system is defined in the Bend arch-Fort Worth Basin as encompassing the area in which the organic-rich Barnett is the primary source rock for oil and gas produced from Paleozoic carbonate and clastic reservoirs. Exploration, technology, and drilling in the Barnett Shale play have rapidly evolved in recent years, with about 3500 vertical and 1000 horizontal wells completed in the Barnett through 2005 and more than 85% of the them completed since 1999. Using framework geology and historical production data, assessment of the Barnett Shale was performed by the U.S. Geological Survey using vertical wells at the peak of vertical well completions and before a transition to completions with horizontal wells. The assessment was performed after (1) mapping critical geological and geochemical parameters to define assessment unit areas with future potential, (2) defining distributions of drainage area (cell size) and estimating ultimate recovery per cell, and (3) estimating future success rates. Two assessment units are defined and assessed for the Barnett Shale continuous gas accumulation, resulting in a total mean undiscovered volume having potential for additions to reserves of 26.2 TCFG. The greater Newark East fracture-barrier continuous Barnett Shale gas assessment unit represents a core-producing area where thick, organic-rich, siliceous Barnett Shale is within the thermal window for gas generation (Ro ??? 1.1%) and is overlain and underlain by impermeable limestone barriers (Pennsylvanian Marble Falls Limestone and Ordovician Viola Limestone, respectively) that serve to confine induced fractures during well completion to maximize gas recovery. The extended continuous Barnett Shale gas assessment unit, which had been less explored, defines a geographic area where Barnett Shale is (1) within the thermal window for gas generation, (2) greater than 100 ft (30 m) thick, and (3) where at least one impermeable limestone barrier is absent. Mean undiscovered gas having potential for additions to reserves in the greater Newark East assessment unit is estimated at 14.6 tcf, and in the less tested extended assessment unit, a mean resource is estimated at 11.6 TCFG. A third hypothetical basin-arch Barnett Shale oil assessment unit was defined but not assessed because of a lack of production data. Copyright ?? 2007.

This research examines whether parental educational attainment and subjective childhood socioeconomic status (SES) is associated with adult offspring well-being and self-beliefs (broadly defined). Participants from the Health and Retirement Study were included if they completed the leave-behind questionnaire in 2006 or 2008 ( N =10,827; M age =68.38; SD =9.81; range=50-101). Participants reported on their own and both parents educational attainment, subjective childhood financial situation, and financial difficulties in childhood at study entry and on well-being in 2006/2008. Linear regression was used to examine the association between offspring education, parental education, childhood SES and three aspects of well-being and self-beliefs: positive affect (e.g., positive emotions, optimism), negative affect (e.g., loneliness, hostility), and cognitive evaluation (e.g., life satisfaction). Participants with more education reported higher well-being (median β=.12). Parental educational attainment, subjective childhood SES, and a significant financial event during childhood were associated with more positive affect, less negative affect, and higher life satisfaction (median β=.05); these associations held controlling for offspring education. The educational and financial environment of childhood may hamper well-being into older adulthood; the offspring's own experiences and achievements do not completely attenuate the association with these aspects of the childhood environment.

Water sources and disposal related to hydraulic fracturing in the Barnett Shale: a historical perspective

NASA Astrophysics Data System (ADS)

Nicot, J.; Scanlon, B. R.

2013-12-01

During the past few years, hydraulic fracturing (HF) has become a hotly debated topic particularly related to volume of water used and potential for contamination of shallow aquifers. In this communication, we focused on water use in the oldest shale play in the world as an example for an analysis of historical patterns of water use, consumption, and disposal. The Barnett Shale play in Texas provides an ideal case to assess some of the issues related to shale gas production. It was the first shale play to submit to intense slick-water HF (first horizontal wells in 2003, ~15,000 horizontal wells completed to date). An estimated 200, 000 acre-feet (247 million m3) of water has been used so far in the play (included for vertical wells), mostly in the 4-5 counties making up the core area. More than 90% of the water used is consumed and relatively little recycling occurs in the play. Most of the flowback / produced water is disposed of through injection wells. The median Barnett horizontal well produces back ~100% of the amount of water injected for fracturing in the course of the few years following completion, an amount larger than other well-known shale gas plays. The communication will provide detailed material documenting these findings.

Ground-water levels in Huron County, Michigan, 2004-05

2006-01-01

In 1990, the U.S. Geological Survey (USGS) completed a study of the hydrogeology of Huron County, Michigan (Sweat, 1991). In 1993, Huron County and the USGS entered into a continuing agreement to measure water levels at selected wells throughout Huron County. As part of the agreement, USGS has operated four continuous water-level recorders, installed from 1988 to 1991 on wells in Bingham, Fairhaven, Grant, and Lake Townships (fig. 1) and summarized the data collected in an annual or bi-annual report. The agreement was altered in 2003, and beginning January 1, 2004, only the wells in Fairhaven and Lake Townships retained continuous waterlevel recorders, while the wells in Grant and Bingham Townships reverted primarily to periodic or quarterly measurement status. USGS also has provided training for County or Huron Conservation District personnel to measure the water level, on a quarterly basis, in 25 wells. USGS personnel regularly accompany County or Huron Conservation District personnel to provide a quality assurance/quality control check of all measurements being made. Water-level data collected from the 25 periodically or quarterly-measured wells is summarized in an annual or bi-annual report. In 1998, the USGS also completed a temporal and spatial analysis of the monitoring well network in Huron County (Holtschlag and Sweat, 1998). The altitude of Lake Huron and precipitation are good indicators of general climatic conditions and, therefore, provide an environmental context for ground-water levels in Huron County. Figure 2 shows the mean-monthly water-level altitude of Lake Huron, averaged from measurements made by the U.S. Army Corps of Engineers at sites near Essexville or Harbor Beach, or both (National Oceanic and Atmospheric Administration, 2003-05), and monthly precipitation measured in Bad Axe (National Oceanic and Atmospheric Administration, 2003-05). In March 2003, a new low-water level for the period from 1991 through 2005 was measured in Lake Huron. There was almost no net change in the water level of Lake Huron from January 2004 through December 2005. In 2004, annual precipitation measured in Port Hope was about 3.7 inches above normal, but precipitation measured in Bad Axe was about 1.4 inches below normal. About 14.5 inches of precipitation was measured in Bad Axe during the 2004 summer growing season (May through August), which is about the same as was measured in Port Hope during the same period. Provisional precipitation totals for 2005 were 30.7 inches for January through November in Port Hope, and about 31.7 inches for the year in Bad Axe. About 10.6 inches of precipitation was measured in Bad Axe during the 2005 summer growing season, which is about 0.2 inches more than was recorded at Port Hope during the same period. Two wells equipped with continuous-data recorders are completed in the Saginaw and Marshall aquifers in Fairhaven and Lake Townships, respectively. From January 2004 through December 2005, the net rise in the water level in the Fairhaven Township well was 0.71 ft, and the net rise in the Lake Township well was 0.98 ft. The Fairhaven Township well is drilled adjacent to Saginaw Bay (Lake Huron), and, as previously noted, there was almost no net change in the water level in Saginaw Bay over the same period. Hydrographs showing water levels are presented for the two wells equipped with continuous-data recorders. Continuous-data recorders were discontinued in the Grant and Bingham Township wells at the end of 2003 due to budget constraints. The decision of which two wells to discontinue was based on an analysis of the intrinsic value to Huron County of data from each well. The Grant Township well was selected for periodic or quarterly measurement at that time because it is completed in the glacial aquifer, which is little used for drinking water purposes or absent in much of Huron County. The Bingham Township well, which is completed in the Marshall aquifer, was selected for

Drilling, Completion, and Data Collection Plans An Assessment of Geological Carbon Sequestration Options in the Illinois Basin: Phase III

2015-05-01

Executive Summary The Illinois Basin – Decatur Project (IBDP) is managed by the Midwest Geological Sequestration Consortium (MGSC) and is led by the Illinois State Geological Survey (ISGS) at the University of Illinois. The project site is located on the Archer Daniels Midland Company (ADM) property in Decatur, Illinois, and is a fully integrated carbon capture and storage (CCS) project that uses CO₂ captured from the ethanol-producing fermentation process at the ADM corn-processing plant (Finley et. al., 2013). IBDP has a goal of injecting one million tonnes of CO₂ into the basal sands of the Mt. Simon Sandstone over amore » three-year period. This is a multifaceted project, and this report details the planning and results of the drilling, completions, well testing, log data acquisition, and the Health, Safety, and Environment (HSE) aspects of the project. Three deep wells were planned for the IBDP: • The injection well: Injection Well #1 (CCS1); • The monitoring well (both in-zone and above seal): Verification Well #1 (VW1); and • The geophone monitoring well: Geophysical Monitoring Well #1 (GM1). The detailed plans for these wells are attached to the appendices of this document. The wells were drilled successfully with little deviation from the original plans. The biggest change from the plan to execution was the need to adjust for larger-than-expected loss of circulation in the Potosi section of the Knox Formation. The completions reports also attached to this document detail the well constructions as they were actually built. Injectivity testing was carried out, and the perforating plans were adjusted based on the results. Additional perforations and acidizing were performed as a result of the injectivity testing. The testing plans are detailed in this report along with the actual testing results. The injectivity testing results were used in the modeling and simulation efforts. Detailed HSE plans were developed and implemented during the planning and execution phases of the project. The implementation included an HSE Bridging Document, which served to unify the HSE policies of the project partners and key subcontractors. The HSE plan and actual HSE results are presented in this document. There were no recordable HSE incidents during the project. A detailed logging program was developed based on project needs. The log data were acquired in accordance with the plan, and both the plan and log results are presented in this report. Log data were heavily utilized by the research staff, modelers, reservoir engineers, and for technical and permitting efforts. 5 Several key lessons were learned during the project: • Safety in operations and execution is paramount and is only achieved through proper planning and behavior control. The certainty of this was reinforced through implementation of this lesson and the resultant flawless HSE performance during the project. • Losses of drilling fluid circulation were larger than anticipated within the Potosi Formation. Circulation was only recovered through cementing the loss zones. • When possible, minimizing complexity in permit requirements and well designs is preferable. • The size of the wells were outside of the standard experience and expertise typical within the basin, and therefore required substantial planning and ramp-up of contractors and partners to meet project objectives. • With multiple stakeholders and research partners, establishing objectives and requirements early and adhering to change request procedures throughout the project are critical to manage competing data and sampling objectives that may be detrimental to overall progress. The well construction and completion operations were successfully executed, with all wells built in a manner that achieved excellent wellbore integrity. Log planning involved a number of stakeholders and technical specialists. Data collection from logging, coring, and testing was excellent. Time and effort spent with the associated contractors and suppliers to develop a well plan beyond normal scope proved highly successful, resulting in a well-construction and completion project that surpassed expectations. The world-class HSE results also demonstrate the commitment of all stakeholders in the project. The details follow in the body of this document« less

OBJECTIVES. Dissatisfaction with services has been associated with poorer child mental health outcomes, early treatment termination as well as disagreements over the nature of mental health difficulties, reasons for referral and therapy goals. The development of straightforward, reliable, and accurate methods of eliciting service users' views is essential within child and adolescent mental health care. This paper describes the development of the child and adolescent service experience (ChASE), a tool to measure children and young people's service experience DESIGN. The study comprises a non-experimental, cross-sectional design. METHODS. Participants were 132 mental health service users aged 8-18 years. Participants and their main carer completed the ChASE, Parent Satisfaction Questionnaire (PSQ) (Stallard, 1996) and Strengths and Difficulties (SDQ) Impact Supplement. Clinicians completed the SDQ Impact Supplement and provided clinical activity data. A sub-sample of participants completed the ChASE on a second occasion, 6 weeks after the completion of the first questionnaire. RESULTS. Scrutiny of ChASE data indicated high levels of completion. Principal axis factoring identified three factors within the ChASE: Relationship, Privacy, and Session Activity. The ChASE has good internal consistency and test-retest reliability. Significant correlations were found between the ChASE and carer satisfaction, service use, and youth clinical outcomes. CONCLUSIONS. The ChASE is a short, psychometrically robust tool for routine measurement of children, and young people's experience of mental health services, which users can complete easily. The results underline the importance of alliance factors to children and young people and their association with clinical improvement as well as the potential for the ChASE to be used a measure of children's therapeutic progress and alliance. ©2011 The British Psychological Society.

The clinical and financial outcomes of annual wellness visits (AWVs) conducted by clinical pharmacists working as part of an accountable care organization (ACO) in a federally qualified health center were evaluated. In this retrospective, single-center, chart review study, patients seen for AWVs at El Rio Health Center between October and December 2013 were eligible for study inclusion. Data collected from patient charts included patient demographics, preventive screenings ordered by clinical pharmacists during the AWV and completed within one month after the visit, other screenings completed by clinical pharmacists during the visit, medication changes by clinical pharmacists, and revenues collected from the AWV and preventive screenings. Descriptive statistics were calculated and variables compared; p values were calculated using single-sample Student's t tests. Three hundred patient records were reviewed. Clinical pharmacists completed 1608 interventions, with a mean of 5.4 interventions per patient. A total of 272 referrals were made, 120 (45%) of which were completed within one month of the visit. Of the 183 laboratory tests ordered for diabetes and lipid screening, 152 (83%) were completed within one month of the AWV (p < 0.001). Of the 370 vaccinations offered during the visits, 182 (49%) were administered (p < 0.001). Twenty-four medication and dosage changes were made by clinical pharmacists during AWVs, and the total revenue for the AWVs conducted by pharmacists and services completed during the visits exceeded $22,000. Recommendations made by pharmacists during AWVs in an ACO associated with a federally qualified health center had a high acceptance rate and generated substantial revenue.

Acute necrotizing pancreatitis (ANP) can affect main pancreatic duct (MPD) as well as parenchyma. However, the incidence and outcomes of MPD disruption has not been well studied in the setting of ANP. This retrospective study investigated 84 of 465 patients with ANP who underwent magnetic resonance cholangiopancreatography and/or endoscopic retrograde cholangiopancreatography. The MPD disruption group was subclassified into complete and partial disruption. MPD disruption was documented in 38% (32/84) of the ANP patients. Extensive necrosis, enlarging/refractory pancreatic fluid collections (PFCs), persistence of amylase-rich output from percutaneous drainage, and amylase-rich ascites/pleural effusion were more frequently associated with MPD disruption. Hospital stay was prolonged (mean 55 vs. 29 days) and recurrence of PFCs (41% vs. 14%) was more frequent in the MPD disruption group, although mortality did not differ between ANP patients with and without MPD disruption. Subgroup analysis between complete disruption (n = 14) and partial disruption (n = 18) revealed a more frequent association of extensive necrosis and full-thickness glandular necrosis with complete disruption. The success rate of endoscopic transpapillary pancreatic stenting across the stricture site was lower in complete disruption (20% vs. 92%). Patients with complete MPD disruption also showed a high rate of PFC recurrence (71% vs. 17%) and required surgery more often (43% vs. 6%). MPD disruption is not uncommon in patients with ANP with clinical suspicion on ductal disruption. Associated MPD disruption may influence morbidity, but not mortality of patients with ANP. Complete MPD disruption is often treated by surgery, whereas partial MPD disruption can be managed successfully with endoscopic transpapillary stenting and/or transmural drainage. Further prospective studies are needed to study these items. Copyright © 2016 IAP and EPC. Published by Elsevier B.V. All rights reserved.

An Advanced Cardiovascular Pharmacotherapy Course Blending Online and Face-to-Face Instruction

PubMed Central

2009-01-01

Objective To assess the effectiveness of online instruction in a cardiology pharmacotherapy elective. Design Eight drug-focused lectures and 6 introductory presentations were added to a cardiology pharmacotherapy course. Students completed an online quiz after each online drug-focused lecture and scores were compared to quizzes taken at the beginning and end of the course, as well as on a cardiology advanced pharmacy practice experience (APPE). For online introductory presentations, students completed a quiz at the beginning of the next face-to-face session. A survey was conducted at the end of the course to obtain student feedback. Assessment Compared to baseline scores, student learning was demonstrated after online drug-focused lectures by higher quiz scores attained immediately after completing the lecture, at the end of the course, and at the beginning of the APPE. Furthermore, students performed better on quizzes at the beginning of face-to-face sessions if they first completed an online introductory presentation. Students expressed strong support for the online components of the course. Conclusions A blended learning environment with online and face-to-face instruction is an effective way to teach a cardiology pharmacotherapy elective. The online component of this course was well received by students, improved student preparation before attending class, and appeared to enhance long-term cardiovascular drug knowledge. PMID:19564994

Cervical spinal motion during intubation: efficacy of stabilization maneuvers in the setting of complete segmental instability.

2001-04-01

The purpose of this study was to characterize and compare segmental cervical motion during orotracheal intubation in cadavers with and without a complete subaxial injury, as well as to examine the efficacy of commonly used stabilization techniques in limiting that motion. Intubation procedures were performed in 10 fresh human cadavers in which cervical spines were intact and following the creation of a complete C4-5 ligamentous injury. Movement of the cervical spine during direct laryngoscopy and intubation was recorded using video fluoroscopy and examined under the following conditions: 1) without stabilization; 2) with manual in-line cervical immobilization; and 3) with Gardner-Wells traction. Subsequently, segmental angular rotation, subluxation, and distraction at the injured C4-5 level were measured from digitized frames of the recorded video fluoroscopy. After complete C4-5 destabilization, the effects of attempted stabilization on distraction, angulation, and subluxation were analyzed. Immobilization effectively eliminated distraction, and diminished angulation, but increased subluxation. Traction significantly increased distraction, but decreased angular rotation and effectively eliminated subluxation. Orotracheal intubation without stabilization had intermediate results, causing less distraction than traction, less subluxation than immobilization, but increased angulation compared with either intervention. These results are discussed in terms of both statistical and clinical significance and recommendations are made.

Private Domestic-Well Characteristics and the Distribution of Domestic Withdrawals among Aquifers in the Virginia Coastal Plain

USGS Publications Warehouse

Pope, Jason P.; McFarland, Randolph E.; Banks, R. Brent

2008-01-01

A comprehensive analysis of private domestic wells and self-supplied domestic ground-water withdrawals in the Coastal Plain Physiographic Province of Virginia indicates that the magnitudes of these withdrawals and their effects on local and regional ground-water flow are larger and more important than previous reports have stated. Self-supplied ground-water withdrawals for domestic use in the Virginia Coastal Plain are estimated to be approximately 40 million gallons per day, or about 28 percent of all ground-water withdrawals in the area. Contrary to widely held assumptions, only 22 percent of domestic wells in the Virginia Coastal Plain are completed in the shallow, unconfined surficial aquifer to which the water is returned directly by home septic systems. Fifty-three percent of the wells are completed in six deeper confined aquifers, and the remaining 25 percent are completed in the Potomac aquifer and confining zone, the deepest units in the confined system. Assuming an equal rate of withdrawal per well, 78 percent of domestic ground-water withdrawal, or about 30 million gallons per day, is removed from the regional confined ground-water system. Domestic ground-water withdrawal from an estimated 200,000 private wells supplies more than 15 percent of the population of the area and provides almost the entire source of water in some rural counties. The geographic distribution of these withdrawals is dependent on the self-supplied population and is highly variable. Domestic-well characteristics vary spatially as well, primarily because of geographic differences in depths to particular aquifers, but also because of well-drilling practices that are influenced by geographic, regulatory, and socioeconomic factors. Domestic ground-water withdrawals in the Virginia Coastal Plain were characterized as part of a larger study to analyze the regional ground-water flow system. Characterizing the withdrawals required differentiation of the withdrawals among the aquifers in the area in addition to determination of the geographic distribution of the withdrawals. Because of a lack of comprehensive data on private-well construction and distribution, a sample of private domestic-well records was used to estimate well characteristics and approximate the proportion of wells and withdrawals associated with each aquifer. Construction data on 2,846 private domestic wells were collected from 29 counties and independent cities (localities) having appreciable self-supplied populations and representing private domestic withdrawals of about 31 million gallons per day. Within each locality, geographically stratified random sampling of well records by tax plat characterized details of well construction for the population of domestic wells. Because neither specific location data nor aquifer elevations were available for individual wells, the primary aquifer in which each well is completed was estimated by cross-referencing the screen elevation estimated from the well record with a generalized configuration of hydrogeologic units underlying the locality in which the well is located. For each locality, summarizing the results of this process allowed the determination of the proportion of wells and withdrawals associated with each aquifer. Additional evaluation of spatial data was used to apply the domestic withdrawal rates developed for each aquifer in each locality to a detailed ground-water study of the portion of the Virginia Coastal Plain east of the Chesapeake Bay, which is known as the Eastern Shore Peninsula. Because domestic withdrawal estimates are based on the self-supplied population, the geographic distribution of withdrawals within each of the Eastern Shore counties was estimated by using population data from the 2000 U.S. Census at the resolution of census block groups and further refining the distribution based on road density. The allocation of withdrawals among aquifers was then determined by cross-referencing the spatial distribut

Design, performance, and analysis of an aquifer thermal-energy-storage experiment using the doublet-well configuration

NASA Astrophysics Data System (ADS)

Molz, F. J.; Melville, J. G.; Gueven, O.; Parr, A. D.

1983-09-01

In March 1980 Auburn University began a series of aquifer thermal energy storage (ATES) experiments using the doublet well configuration. The test site was in Mobile, Alabama. The objectives of the three experimental cycles were to demonstrate the technical feasibility of the ATES concept, to identify and resolve operational problems, and to acquire a data base for developing and testing mathematical models. Pre-injection tests were performed and analyses of hydraulic, geochemical, and thermodynamic data were completed. Three injection-storage-recovery cycles had injection volumes of 25,402 m(3), 58,010 m(3), and 58,680 m(3) and average injection temperatures of 58.50C, 81.00C. and 79.00C, respectively. The first cycle injection began in February 1981 and the third cycle recovery was completed in November 1982. Attributable to the doublet well configuration no clogging of injection wells occurred. Energy recovery percentages based on recovery volumes equal to the injection volumes were 56, 45, and 42%. Thermal convection effects were observed. Aquifer nonhomogeneity, not detectable using standard aquifer testing procedures, was shown to reduce recovery efficiency.

In 1948, the World Health Organization defined health as 'a state of complete physical, mental, and social well-being, and not merely the absence of disease or infirmity'. Detractors claim that this definition of health is utopian and unrealistic. However, accumulating evidence from experimental studies suggests that aging is not inevitably linked with the development of chronic diseases, and the age-associated accumulation of molecular damage can be prevented or greatly delayed by dietary and genetic manipulations that downregulate key cellular nutrient-sensing pathways. Nonetheless, to obtain a state of complete physical, mental, and social well-being, we as human beings need to go beyond nutrition or pharmacological treatments and implement a combination of interventions that enhance not only our metabolic health but also our psychological, emotional, intellectual and spiritual development, our social relationships and cultural well-being. This perspective highlights a range of scientific research-based interventions that can potentially be used to promote human health and longevity. We will also briefly address the importance of environmental health in achieving this goal. © 2016 S. Karger AG, Basel.

Vetter, O.J.; Campbell, D.A.

Two calcium carbonate (CaCO/sub 3/) scale inhibition tests have been performed at East Mesa wells number 16-29 and number 56-30. The first test at well number 16-29 could not be finished due to downhole pump problems. However, two inhibitor concentration runs were completed and a third run started before the pump failed. A follow-up test at well number 56-30 was completed according to the original plan. Typical power plant conditions (i.e., pressure and temperature drops, flow conditions) were simulated by using test loops (pipe diameters of eight inches at well number 16-29 and twelve inches at well number 56-30) andmore » field separators. Untreated East Mesa brine exhibits a calcium carbonate scale tendency as soon as the pressure is dropped below 75 psig. The uninhibited brine from well number 16-29 formed a maximum scale thickness of 0.5 inch in an eight inch ID pipe after a 92.75 hour test run at an average production rate of 375,000 lb/hr. The brine from well number 56-30 formed a maximum scale thickness of 1.25 inches in a twelve inch ID pipe after a 104 hour test run at an average production rate of 722,000 lb/hr.

The Qatar Petroleum Producing Authority is presently operating three offshore fields - Idd al-Shargi, Maydan Mahzam and Bul Hanine. The Idd al-Shargi field consists of 14 naturally flowing wells and three suspended wells. Individual flow rates of the producing wells range from 250 to 3000 barrels per day (b/d). The Maydan Mahzam field produces from 11 naturally flowing wells. Reservoir energy in the field is maintained by water injection. Each of the wells produce oil at rates ranging from 2500 to 20,000 b/d. The Bul Hanine field comprises 10 producing wells supported by 9 dumpflooders. Production rates of the individualmore » wells reach 29,000 b/d, making them among the world's highest. In 1978 the completion of a major acceleration project for the Bul Hanine Arab IV reservoir added more than 40,000 b/d to the production potential of the field. Total Qatari oil exports in 1978 were 91,708,000 barrels, equivalent to an average export rate of 25,000 b/d. Total production in Qatar in 1979 was 100,641,394 barrels (offshore) and 84,130,917 (onshore), an increase of 11% and a decrease of 3%, respectively, over 1978. Halal Island provides offshore storage for oil and gas berthing and loading operations. A natural gas liquids offshore complex, including a fractionation plant, is nearing completion at Umm Said.

This paper describes the implementation of comprehensive well testing programs during the 2014-2015 exploration drilling in Rantau Dedap Geothermal Field. The well testing programs were designed to provide reliable data as foundation for resource assessment as well as useful information for decision making during drilling. A series of well testing survey consisting of SFTT, completion test, heating-up downhole logging, discharge test, chemistry sampling was conducted to understand individual wells characteristics such as thermodynamic state of the reservoir fluid, permeability distribution, well output and fluid chemistry. Furthermore, interference test was carried out to investigate the response of reservoir to exploitation.

Hydrogeology and groundwater quality of the glaciated valleys of Bradford, Tioga, and Potter Counties, Pennsylvania

USGS Publications Warehouse

Williams, John H.; Taylor, Larry E.; Low, Dennis J.

1998-01-01

The most important sources of groundwater in Bradford, Tioga, and Potter Counties are the stratified-drift aquifers. Saturated sand and gravel primarily of outwash origin forms extensive unconfined aquifers in the valleys. Outwash is underlain in most major valleys by silt, clay, and very fine sand of lacustrine origin that comprise extensive confining units. The lacustrine confining units locally exceed 100 feet in thickness. Confined aquifers of ice-contact sand and gravel are buried locally beneath the lacustrine deposits. Bedrock and till are the basal confining units of the stratifies-drift aquifer systems. Recharge to the stratified-drift aquifers if by direct infiltration of precipitation, tributary-stream infiltration, infiltration of unchanneled runoff at the valley walls, and groundwater inflow from the bedrock and till uplands. Valley areas underlain by superficial sand and gravel contribute about 1 million gallons per day per square mile of water from precipitation to the aquifers. Tributary streams provide recharge of nearly 590 gallons per day per foot of stream reach. Water is added at the rate of 1 million gallons per day per square mile of bordering uplands not drained by tributary streams to the stratified-drift aquifers from unchanneled runoff and groundwater inflow. Induced infiltration can be a major source of recharge to well fields completed in unconfined stratified-drift aquifers that are in good hydraulic connection with surface water. The well fields of an industrial site in North Towanda, a public-water supplier at Tioga Point, and the U.S. Fish and Wildlife Service at Asaph accounted for 75 percent of the 10.8 million gallons per day pf groundwater withdrawn by public suppliers and other selected users in 1985. The well fields tap stratified-drift aquifers that are substantially recharged by induced infiltration or tributary-stream infiltration. Specific-capacity data from 95 wells indicate that most wells completed in stratified-drift aquifers have specific capacities an order of magnitude greater than those completed in till and bedrock, Wells completed in unconfined stratified-drift aquifers and in bedrock aquifers have the highest and lowest median specific capacities -- 24 and 0.80 gallons per minute per foot of drawdown, respectively. Wells completed in confined stratified-drift aquifers and in till have median specific capacties of 11 and 0.87 gallons per minute per foot of drawdown, respectively. The results of 223 groundwater-quality analyses indicate two major hydrogeochemical zones: (1) a zone of unrestricted groundwater flow that contains water of the calcium bicarbonate type (this zone is found in almost all of the stratified-drift aquifers, till, and shallow bedrock systems); and (2) a zone of restricted groundwater slow that contains water of the sodium chloride type (this zone is found in the bedrock, and, in some areas, in till and confined stratified-drift aquifers). Samples pumped from wells that penetrate restricted-flow zones have median concentrations of total dissolved solids, dissolved chloride, and dissolved barium of 840 and 350 milligrams per liter, and 2,100 micrograms per liter, respectively. Excessive concentrations of iron and manganese are common in the groundwater of the study area; about 50 percent of the wells sampled contain water that has iron and manganese concentrations that exceed the U.S. Environmental Protection Agency secondary maximum contaminant levels of 300 and 50 micrograms per liter, respectively. Only water in the unconfined stratified-drift aquifers and the Catskill Formation has median concentrations lower than these limits.

Logging while fishing technique results in substantial savings

Tollefsen, E.; Everett, M.

1996-12-01

During wireline logging operations, tools occasionally become stuck in the borehole and require fishing. A typical fishing job can take anywhere from 1{1/2}--4 days. In the Gulf of Mexico, a fishing job can easily cost between $100,000 and $500,000. These costs result from nonproductive time during the fishing trip, associated wiper trip and relogging the well. Logging while fishing (LWF) technology is a patented system capable of retrieving a stuck fish and completing the logging run during the same pipe descent. Completing logging operations using LWF method saves time and money. The technique also provides well information where data maymore » not otherwise have been obtained. Other benefits include reduced fishing time and an increased level of safety.« less

The aim of this study was to measure income-related inequality in completed suicide across the provinces of Iran. This ecological study was performed using data from the Urban and Rural Household Income and Expenditure Survey-2010 conducted by the Iranian Center of Statistics, along with data on completed suicide from the Iranian Legal Medicine Organization in 2012. We calculated the Gini coefficient of per capita income and the completed suicide rate, as well as the concentration index for per capita income inequality in completed suicide, across the provinces of Iran. The Gini coefficients of per capita income and the completed suicide rate in the provinces of Iran were 0.10 (95% confidence interval [CI], 0.06 to 0.13) and 0.34 (95% CI, 0.21 to 0.46), respectively. We found a trivial decreasing trend in the completed suicide incidence rate according to income quintile. The poorest-to-richest ratio in the completed suicide rate was 2.01 (95% CI, 1.26 to 3.22). The concentration index of completed suicide in the provinces of Iran was -0.12 (95% CI, -0.30 to 0.06). This study found that lower income might be considered as a risk factor for completed suicide. Nonetheless, further individual studies incorporating multivariable analysis and repeated cross-sectional data would allow a more fine-grained analysis of this phenomenon.

Construction and validation of a measure of integrative well-being in seven languages: The Pemberton Happiness Index

PubMed Central

2013-01-01

Purpose We introduce the Pemberton Happiness Index (PHI), a new integrative measure of well-being in seven languages, detailing the validation process and presenting psychometric data. The scale includes eleven items related to different domains of remembered well-being (general, hedonic, eudaimonic, and social well-being) and ten items related to experienced well-being (i.e., positive and negative emotional events that possibly happened the day before); the sum of these items produces a combined well-being index. Methods A distinctive characteristic of this study is that to construct the scale, an initial pool of items, covering the remembered and experienced well-being domains, were subjected to a complete selection and validation process. These items were based on widely used scales (e.g., PANAS, Satisfaction With Life Scale, Subjective Happiness Scale, and Psychological Well-Being Scales). Both the initial items and reference scales were translated into seven languages and completed via Internet by participants (N = 4,052) aged 16 to 60 years from nine countries (Germany, India, Japan, Mexico, Russia, Spain, Sweden, Turkey, and USA). Results Results from this initial validation study provided very good support for the psychometric properties of the PHI (i.e., internal consistency, a single-factor structure, and convergent and incremental validity). Conclusions Given the PHI’s good psychometric properties, this simple and integrative index could be used as an instrument to monitor changes in well-being. We discuss the utility of this integrative index to explore well-being in individuals and communities. PMID:23607679

Acetylcholine, nicotine, a selective agonist of N-cholinoreceptors suberildicholine dibromide, as well as a selective agonist of M-cholinoreceptors 5-methylfurmethide inhibited spike discharges in a dose-dependent manner up to a complete ceasing of the firing in cholinoreceptors situated on the identified neurone TAN of African giant snail Achatina fulica. M-cholinoblocker metamizylum completely prevented the inhibitory effect of methylfurmethide. Central cholinoblocker aetherophen completely prevented the inhibitory effect of suberildicholine dibromide. Metamizylum or aetherophen used alone were only able to decrease the inhibitory effect of acetylcholine, whereas a mixture of these agents suppressed completely the acetylcholine-induced inhibition. The findings suggest that, on the TAN membrane, nicotinic and muscarinic cholinoreceptors co-exist and function in one and the same direction.

To examine factors that enhance under-screened and never-screened women's completion of the self-collection alternative pathway of the Renewed National Cervical Screening Program (ncsp) in Victoria, Australia. With the Australian ncsp changing, starting on 1 December 2017, the Medical Services Advisory Committee (msac) recommended implementing human papillomavirus (hpv) testing using a self-collected sample for under-screened and never-screened populations. In response, a multi-agency group implemented an hpv self-collection pilot project to trial self-collection screening pathways for eligible women. Quantitative data were collected on participation rates and compliance rates with follow-up procedures across three primary health care settings. Forty women who self-collected were interviewed in a semi-structured format, and seven agency staff completed in-depth interviews. Qualitative data were used to identify and understand clinical and personal enablers that assisted women to complete self-collection cervical screening pathways successfully. Eighty-five per cent (10 women) of participants who tested positive for hpv successfully received their results and completed follow-up procedures as required. Two remaining participants also received hpv-positive results. However, agencies were unable to engage them in follow-up services and procedures. The overall participation rate in screening (self-collection or Pap test) was 85.7% (84 women), with 79 women self-collecting. Qualitative data indicated that clear explanations on self-collection, development of trusting, empathetic relationships with health professionals, and recognition of participants' past experiences were critical to the successful completion of the self-collection pathway. When asked about possible inhibitors to screening and to following up on results and appointments, women cited poor physical and mental health, as well as financial and other structural barriers. A well-implemented process, led by trusted, knowledgeable, and engaged health care professionals who can provide appropriate support and information, can assist under-screened and never-screened women to complete the hpv self-collection pathway successfully.

Review of Vedder pool development, Kern River field, Kern County, California

DOE Office of Scientific and Technical Information (OSTI.GOV)

Condon, M.W.

1986-07-01

The Kern River field is located on the east side of the San Joaquin Valley, just north of Bakersfield, California. Since its discovery in 1899, the field has produced over 1 billion bbl of heavy oil from the Kern River Formation. It was not until 1981 that light oil was discovered from a deeper zone, the Vedder formation. The discovery well, Getty Oil Company WD-1 Apollo, encountered 40 ft of net oil sand within the third Vedder sand and was completed on pump for an initial production of 100 bbl of 40.5/sup 0/ API oil and 200 MCDGD. As suggestedmore » by its name, WD-1 Apollo was drilled as a water-water injection wells. However, a detailed subsurface study of the field suggested the possibility of a trap within the Vedder formation. The originally proposed location of WD-1 Apollo was then moved to test the proposal. The trap is a series of intersecting, up-to-the-basin normal faults trending west and northwest. These faults have dropped impermeable silty zones within the Vedder formation against the productive Vedder sands. Since the completion of WD-1 Apollo, nine other wells have been drilled within this pool, extending production over 1 mi to the southeast. One of the first of the extension wells, Getty Oil Company 73X Central Point, located approximately 600 ft southeast of WD-1 Apollo, established production from the second Vedder sand. This well was completed flowing 300 b/d of 32/sup 0/ API oil and 1000 MCFGD through a 16/64-in. choke. Through December 1985, Texaco (Getty Oil) produced more than 250,000 bbl of oil and 350,000 mcf of gas combined from the second and third Vedder sands from 2.5 net wells. Although attempts to find other such Vedder pools have met with limited success, there is still the potential for many to exist, given proper structural closure, as seen in the Apollo pool.« less

Evaluating the Relationship Between Seismicity and Subsurface Well Activity in Utah

Lajoie, L. J.; Bennett, S. E. K.

2014-12-01

Understanding the relationship between seismicity and subsurface well activity is crucial to evaluating the seismic hazard of transient, non-tectonic seismicity. Several studies have demonstrated correlations between increased frequency of earthquake occurrence and the injection/production of fluids (e.g. oil, water) in nearby subsurface wells in intracontinental settings (e.g. Arkansas, Colorado, Ohio, Oklahoma, Texas). Here, we evaluate all earthquake magnitudes for the past 20-30 years across the diverse seismotectonic settings of Utah. We explore earthquakes within 5 km and subsequent to completion dates of oil and gas wells. We compare seismicity rates prior to well establishment with rates after well establishment in an attempt to discriminate between natural and anthropogenic earthquakes in areas of naturally high background seismicity. In a few central Utah locations, we find that the frequency of shallow (0-10 km) earthquakes increased subsequent to completion of gas wells within 5 km, and at depths broadly similar to bottom hole depths. However, these regions typically correspond to mining regions of the Wasatch Plateau, complicating our ability to distinguish between earthquakes related to either well activity or mining. We calculate earthquake density and well density and compare their ratio (earthquakes per area/wells per area) with several published metrics of seismotectonic setting. Areas with a higher earthquake-well ratio are located in relatively high strain regions (determined from GPS) associated with the Intermountain Seismic Belt, but cannot be attributed to any specific Quaternary-active fault. Additionally, higher ratio areas do not appear to coincide with anomalously high heat flow values, where rocks are typically thermally weakened. Incorporation of timing and volume data for well injection/production would allow for more robust temporal statistical analysis and hazard analysis.

Compassion, Mindfulness, and the Happiness of Healthcare Workers.

Benzo, Roberto P; Kirsch, Janae L; Nelson, Carlie

Decreased well-being of healthcare workers expressed as stress and decreased job satisfaction influences patient safety, patient satisfaction, and cost containment. Self-compassion has garnered recent attention due to its positive association with well-being and happiness. Discovering novel pathways to increase the well-being of healthcare workers is essential. This study sought to explore the influence of self-compassion on employee happiness in healthcare professionals. A total of 400 participants (mean age = 45 ± 14, 65% female) healthcare workers at a large teaching hospital were randomly asked to complete questionnaires assessing their levels of happiness and self-compassion, life conditions, and habits. Participants completed the Happiness Scale and Self-Compassion Scales, the Five Facet Mindfulness Questionnaire as well as variables associated with well-being: relationship status, the number of hours spent exercising a week, attendance at a wellness facility, and engagement in a regular spiritual practice. Self-compassion was significantly and independently associated with perceived happiness explaining 39% of its variance after adjusting for age, marital status, gender, time spent exercising, and attendance to an exercise facility. Two specific subdomains of self-compassion from the instrument used, coping with isolation and mindfulness, accounted for 95% of the self-compassion effect on happiness. Self-compassion is meaningfully and independently associated with happiness and well-being in healthcare professionals. Our results may have practical implications by providing specific self-compassion components to be targeted in future programs aimed at enhancing well-being in healthcare professionals.

A description is given of the equations and the computer program being developed to model the complete Otto cycle. The program incorporates such important features as: (1) heat transfer, (2) finite combustion rates, (3) complete chemical kinetics in the burned gas, (4) exhaust gas recirculation, and (5) manifold vacuum or supercharging. Changes in thermodynamic, kinetic and transport data as well as model parameters can be made without reprogramming. Preliminary calculations indicate that: (1) chemistry and heat transfer significantly affect composition and performance, (2) there seems to be a strong interaction among model parameters, and (3) a number of cycles must be calculated in order to obtain steady-state conditions.

1995-01-01

Experimental evidence was obtained to complete the verification of the parameters needed for input to a three-dimensional finite element model simulating the resin flow and cure through an orthotropic fabric preform. The material characterizations completed include resin kinetics and viscosity models, as well as preform permeability and compaction models. The steady-state and advancing front permeability measurement methods are compared. The results indicate that both methods yield similar permeabilities for a plain weave, bi-axial fiberglass fabric. Also, a method to determine principal directions and permeabilities is discussed and results are shown for a multi-axial warp knit preform. The flow of resin through a blade-stiffened preform was modeled and experiments were completed to verify the results. The predicted inlet pressure was approximately 65% of the measured value. A parametric study was performed to explain differences in measured and predicted flow front advancement and inlet pressures. Furthermore, PR-500 epoxy resin/IM7 8HS carbon fabric flat panels were fabricated by the Resin Transfer Molding process. Tests were completed utilizing both perimeter injection and center-port injection as resin inlet boundary conditions. The mold was instrumented with FDEMS sensors, pressure transducers, and thermocouples to monitor the process conditions. Results include a comparison of predicted and measured inlet pressures and flow front position. For the perimeter injection case, the measured inlet pressure and flow front results compared well to the predicted results. The results of the center-port injection case showed that the predicted inlet pressure was approximately 50% of the measured inlet pressure. Also, measured flow front position data did not agree well with the predicted results. Possible reasons for error include fiber deformation at the resin inlet and a lag in FDEMS sensor wet-out due to low mold pressures.

2017-01-01

Flexible working time arrangements are becoming increasingly popular around the globe, but do they actually benefit employees? To address this question, we take a differentiated look at employees' day-specific use of flextime and its effect on the intersection of work and nonwork life. Specifically, we examined whether links between day-specific flextime use and affective well-being at work and at home can be explained by level of goal completion and the subjective boundaries around one's work and private life domains (i.e., the strength of work-nonwork boundaries ). During 2 consecutive workweeks, 150 bank employees from various functions (Study 1) and a heterogeneous sample of 608 employees (Study 2) reported their day-specific use of flextime, boundary strength at work and home, and affective well-being in the evening and the next day. Multilevel structural equation modeling of 2,223 (Study 1) and 3,164 (Study 2) observations revealed that flextime use was associated with stronger boundaries at home in both studies and stronger boundaries at work in Study 2. Stronger boundaries were, in turn, positively associated with affective well-being, both in the same evening and the next day. Study 2 further revealed that day-specific nonwork goal completion mediated the positive association between daily flextime use and boundary strength at work. However, whereas occasional flextime use had unequivocal positive consequences, chronic flextime use undermined the completion of work goals. Overall, findings suggest that flextime use benefits employees when used in moderation. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

The complete plastome sequencing is an efficient option for increasing phylogenetic resolution and evolutionary studies, as well as may greatly facilitate the use of plastid DNA markers in plant population genetic studies. Merostachys and Guadua stand out as the most common and the highest potential utilization bamboos indigenous of Brazil. Here, we sequenced the complete plastome sequences of the Brazilian Guadua chacoensis and Merostachys sp. to perform full plastome phylogeny and characterize the occurrence, type, and distribution of SRRs using 20 Bambuseae species. The determined plastome sequence of Merostachys sp. and G. chacoensis is 136,334 and 135,403 bp in size, respectively, with an identical gene content and typical quadripartite structure consisting of a pair of IRs separated by the LSC and SSC regions. The Maximum Likelihood and Bayesian Inference analyses produced phylogenomic trees identical in topology. These trees supported monophyly of Paleotropical and Neotropical Bamboos clades. The Neotropical bamboos segregated into three well-supported lineages, Chusqueinae, Guaduinae, and Arthrostylidiinae, with the last two forming a well-supported sister relationship. Paleotropical bamboos segregated into two well-supported lineages, Hickeliinae and Bambusinae + Melocanninae. We identified 141.8 cpSSR in Bambuseae plastomes and an inferior value (38.15) for plastome coding sequences. Among them, we identified 16 polymorphic SSR loci, with number of alleles varying from 3 to 10. These 16 polymorphic cpSSR loci in Bambuseae plastome can be assessed for the intraspecific level of polymorphism, leading to innovative highly sensitive phylogeographic and population genetics studies for this tribe.

Education is closely associated with health. Non-completion of upper secondary school influences academic achievement, employment, income and personal well-being. The purpose of the study is to explore predictors of non-completion of upper secondary school among female and male young adults in relation to mental health and educational factors in a socio-cultural, Arctic context. The Norwegian Arctic Adolescent Health Study (NAAHS) is a cross-sectional, school-based survey that was conducted in 2003-2005. Eighty-three percent of the population of 5,877 10th graders participated; 49.1%females, 450 reported indigenous Sami ethnicity, and 304 reported Laestadian affiliation. Data from NAAHS were merged with registry data from the National Education Database (NUDB) Norway for 3,987 adolescents who gave their consent for follow-up studies. Non-completion of upper secondary school was 36.9 % among females and 36.6 % among males. Among females, predictors for non-completion were related to mental health symptoms, and among males, to residency in the northernmost and remote areas and self-reported functional difficulties at school, home and in leisure activities due to mental health problems. There was marginal significance between ethnicity and non-completion of upper secondary school, measured at 41.3 % for Sami and 36.8 % for non-Sami, respectively. The gender differences found in this study emphasize the need for gender-specific interventions in preventing non-completion of upper secondary school. There is a need to recognize and treat extensive pro-social behaviour and social problems in young females. Young males from remote areas and those who in early adolescence struggle with functional impairment due to mental health problems need early interventions in lower secondary school. Enhancing parents' and teachers' ability to detect symptoms and problems as well as low-threshold health services starting in primary school can be effective means. Education, mental health and social inclusion are prominent factors for future employment, income and independent living for young people. Future research should focus more on gender-specific patterns of risk and protective factors for completion of upper secondary school.

Ormat sited 2 full-size exploration wells based on 3D seismic interpretation of fractures, prior drilling results, and temperature anomaly. The wells indicated commercial temperatures (>300 F), but almost no permeability, despite one of the wells being drilled within 820 ft of an older exploration well with reported indications of permeability. Following completion of the second well in 2012, Ormat undertook a lengthy program to 1) evaluate the lack of observed permeability, 2) estimate the likelihood of finding permeability with additional drilling, and 3) estimate resource size based on an anticipated extent of permeability.

The goal of this study was to determine the relationship between individual well-being and risk of a hospital event in the subsequent year. The authors hypothesized an inverse relationship in which low well-being predicts higher likelihood of hospital use. The study specifically sought to understand how well-being segments and demographic variables interact in defining risk of a hospital event (inpatient admission or emergency room visit) in an employed population. A retrospective study design was conducted with data from 8835 employees who completed a Well-Being Assessment questionnaire based on the Gallup-Healthways Well-Being Index. Cox proportional hazards models were used to examine the impact of Individual Well-Being Score (IWBS) segments and member demographics on hazard ratios (HRs) for a hospital event during the 12 months following assessment completion. Significant main effects were found for the influence of IWBS segments, sex, education, and relationship status on HRs of a hospital event, but not for age. However, further analysis revealed significant interactions between age and IWBS segments (P=0.005) and between age and sex (P<0.0001), indicating that the effects for IWBS segments and sex on HRs of a hospital event are mediated through their relationship with age. Overall, the strong relationship between low well-being and higher risk of an event in employees ages 44 years and older is mitigated in younger age groups. These results suggest that youth attenuates the risk engendered in poor well-being; therefore, methods to maintain or improve well-being as individuals age presents a strong opportunity for reducing hospital events.

Samples were collected from 59 noncommunity water supplies in the Commonwealth of Pennsylvania from September 2000 to January 2001 and analyzed for pathogens and microbiological indicator organisms. The pathogens sampled were culturable viruses and Helicobacter pylori (H. pylori). The indicator organisms sampled were total coliform, Escherichia coli (E. coli), Clostridium perfringens (C. perfringens), somatic coliphage, male- specific coliphage, and enterococcus. The two primary areas sampled for the project completed by the U.S. Geological Survey, in cooperation with the Pennsylvania Department of Environmental Protection (PaDEP), were carbonate aquifers and crystalline aquifers. The results of all sampling showed culturable viruses were detected in 8 percent of the wells, H. pyloriin 7 percent of the wells, E. coli in 12 percent of the wells, total coliform in 46 percent of the wells, C. perfringens in 15 percent of the wells, somatic coliphage in 8 percent of the wells, male-specific coliphage in 5 percent of the wells, and enterococcus in 14 percent of the wells. Carbonate aquifers tended to have higher detection rates for the pathogens and indicators sampled than the crystalline aquifers. Detections of the pathogens and indicator organisms were not related statistically to the amounts of urban, agricultural, or forested area in a 1,500-foot radius around the sampled well. Somatic and male-specific coliphage showed the best relation to occurrence of culturable viruses. Culturable viruses and H. pylori were detected in wells in which no indicator organisms were present; therefore, none of the indicator organisms sampled provide complete assurance of pathogenfree water. The best predictive tool for virus screening was a combination of indicator organisms.

Effects of seasonal operation on the quality of water produced by public-supply wells.

PubMed

Bexfield, Laura M; Jurgens, Bryant C

2014-09-01

Seasonal variability in groundwater pumping is common in many places, but resulting effects of seasonal pumping stress on the quality of water produced by public-supply wells are not thoroughly understood. Analysis of historical water-quality samples from public-supply wells completed in deep basin-fill aquifers in Modesto, California (134 wells) and Albuquerque, New Mexico (95 wells) indicates that several wells have seasonal variability in concentrations of contaminants of concern. In Modesto, supply wells are more likely to produce younger groundwater with higher nitrate and uranium concentrations during the summer (high) pumping season than during the winter (low) pumping season. In Albuquerque, supply wells are more likely to produce older groundwater with higher arsenic concentrations during the winter pumping season than during the summer pumping season. Seasonal variability in contaminant concentrations in Modesto is influenced primarily by effects of summer pumping on vertical hydraulic gradients that drive migration of shallow groundwater through the aquifer to supply wells. Variability in Albuquerque is influenced primarily by the period of time that a supply well is idle, allowing its wellbore to act as a conduit for vertical groundwater flow and contaminant migration. However, both processes are observed in each study area. Similar findings would appear to be likely in other alluvial basins with stratified water quality and substantial vertical head gradients. Results suggest that even in aquifers dominated by old groundwater, changes to seasonal pumping patterns and/or to depth of well completion can help reduce vulnerability to selected contaminants of either natural or anthropogenic origin.

Purpose. To evaluate the feasibility of using contrast-enhanced ultrasound (CEUS) during uterine artery embolization (UAE) in order to define the correct end-point of embolization with complete devascularization of all fibroids. Methods. In this prospective study of 10 consecutive women undergoing UAE, CEUS was performed in the angiographic suite during embolization. When the angiographic end-point, defined as the 'pruned-tree' appearance of the uterine arteries was reached, CEUS was performed while the angiographic catheters to both uterine arteries were kept in place. The decision whether or not to continue the embolization was based on the findings at CEUS. The results of CEUSmore » were compared with those of contrast-enhanced magnetic resonance imaging (MRI) 1 day as well as 3 months following UAE. Results. CEUS was successfully performed in all women. In 4 cases injection of particles was continued based on the findings at CEUS despite angiographically complete embolization. CEUS imaging at completion of UAE correlated well with the findings at MRI. Conclusion. The use of CEUS during UAE is feasible and may increase the quality of UAE.« less

Schmidt, Cecilia A.; Drost, Charles A.; Halvorson, William Lee

2006-01-01

Executive Summary We summarize past inventory efforts for vascular plants and vertebrates at Montezuma Castle National Monument (NM) in Arizona. We used data from previous research to compile complete species lists for the monument and to assess inventory completeness. There have been 784 species recorded at Montezuma Castle NM, of which 85 (11%) are non-native. In each taxon-specific chapter we highlight areas of resources that contributed to species richness or unique species for the monument. Of particular importance are Montezuma Well and Beaver and Wet Beaver creeks and the surrounding riparian vegetation, which are responsible for the monument having one of the highest numbers of bird species in the Sonoran Desert Network of park units. Beaver Creek is also home to populations of federally-listed fish species of concern. Other important resources include the cliffs along the creeks and around Montezuma Well (for cliff and cave roosting bats). Based on the review of past studies, we believe the inventory for most taxa is nearly complete, though some rare or elusive species will be added with additional survey effort. We recommend additional inventory, monitoring and research studies.

2003-08-01

The goal of the project has been to develop new types of drill-in fluids (DIFs) and completion fluids (CFs) for use in natural gas reservoirs. Phase 1 of the project was a 24-month study to develop the concept of advanced type of fluids usable in well completions. Phase 1 tested this concept and created a kinetic mathematical model to accurately track the fluid's behavior under downhole conditions. Phase 2 includes tests of the new materials and practices. Work includes the preparation of new materials and the deployment of the new fluids and new practices to the field. The project addressesmore » the special problem of formation damage issues related to the use of CFs and DIFs in open hole horizontal well completions. The concept of a ''removable filtercake'' has, as its basis, a mechanism to initiate or trigger the removal process. Our approach to developing such a mechanism is to identify the components of the filtercake and measure the change in the characteristics of these components when certain cleanup (filtercake removal) techniques are employed.« less

2012-07-01

In the General Electric's Economic simplified boiling water reactor (GE-ESBWR) the passive containment cooling system (PCCS) plays a major role in containment pressure control in case of an loss of coolant accident. The PCCS condenser must be able to remove sufficient energy from the reactor containment to prevent containment from exceeding its design pressure following a design basis accident. There are three PCCS condensation modes depending on the containment pressurization due to coolant discharge; complete condensation, cyclic venting and flow through mode. The present work reviews the models and presents model predictive capability along with comparison with existing data frommore » separate effects test. The condensation models in thermal hydraulics code RELAP5 are also assessed to examine its application to various flow modes of condensation. The default model in the code predicts complete condensation well, and basically is Nusselt solution. The UCB model predicts through flow well. None of condensation model in RELAP5 predict complete condensation, cyclic venting, and through flow condensation consistently. New condensation correlations are given that accurately predict all three modes of PCCS condensation. (authors)« less

2015-10-25

Objective. To evaluate how effectively pharmacy students and practicing pharmacists communicate and apply knowledge to simulations of commonly encountered patient scenarios using an objective structured clinical examination (OSCE). Design. Second-, third-, and fourth-year pharmacy students completed an OSCE as part of their required courses in 2012 and 2013. All students in both years completed identical OSCE cases. Licensed pharmacists were recruited to complete the OSCE and serve as controls in 2012. A survey assessed student perception and acceptance of the OSCE as well as student confidence in performance. Assessment. Licensed pharmacists had significantly higher clinical and communication skills scores than did pharmacy students. Student progression in communication and clinical skills improved significantly over time. Survey results indicated that students felt the OSCE was well-structured and assessed clinical skills taught in pharmacy school; 86% of students felt confident they could provide these skills. Conclusion. Objective structured clinical examinations can evaluate clinical competence and communication skills among professional students. Implementation of OSCEs may be an effective tool for assessment of the Center for the Advancement of Pharmacy Education domains.

Extramammary Paget's disease (EMPD) is a rare cancer. Although EMPD is usually noninvasive and treated with local therapy, once metastatic the prognosis of EMPD is poor and treatment options are limited. We report a case of a complete response to single agent trastuzumab in a hemodialysis patient with metastatic Her2/neu overexpressed EMPD of the scrotum. Molecular profiling of his case as well as 12 other EMPD and 8 mammary Paget disease (MPD) cases was completed and revealed multiple biomarker aberrations. Overexpression of Her2 was frequently noted (30%–40%) in both EMPD and MPD patients and when present can be effectively treated with Her2 targeted agents. Trastuzumab therapy can be safely utilized in a hemodialysis patient. In addition, multiple protein overexpression and loss were seen in EMPD including PD-1, PD-L1, PTEN, and AR as well as PIK3CA mutation. These findings may lead to possible therapeutic interventions targeting these pathways in a disease with few effective treatment options. PMID:25692060

Cancer-Related Worry and Physical Well-Being in the Context of Perceived Stress in Young Adults with Testicular Cancer.

PubMed

Darabos, Katie; Hoyt, Michael A

2017-06-01

Uncertainty associated with cancer can foster future-focused worry and ultimately diminish physical well-being, especially among young adult survivors. Stress perceptions might exacerbate the association of worry and physical well-being. Young adults with testicular cancer (N = 171) completed measures of physical well-being, perceived stress, and future cancer-related worry. Perceived stress and future worry were both negatively associated with physical well-being. Perceived stress moderated the relationship; more perceived stress was related to lower physical well-being in those with high worry. Interventions aimed at worry reduction might benefit from reducing global stress perceptions.

This study compares rates of completion of client intake forms (CIFs) collected via three interview modes: audio computer-assisted self-interview (ACASI), face-to-face interview (FFI), and self-administered paper-based interview (SAPI). A total of 303 clients served through the Avon Breast Health Outreach Program (BHOP) were sampled from three U.S. sites. Clients were randomly assigned to complete a standard CIF via one of the three interview modes. Logistic regression analyses demonstrated that clients were significantly more likely to complete the entire CIF via ACASI than either FFI or SAPI. The greatest observed differences were between ACASI and SAPI; clients were almost six times more likely to complete the CIF via ACASI as opposed to SAPI (AOR = 5.8, p < .001). We recommend that where feasible, ACASI be utilized as an effective means of collecting client-level data in healthcare settings. Adoption of ACASI in health centers may translate into higher completion rates of intake forms by clients, as well as reduced burden on clinic staff to enter data and review intake forms for completion. © 2013 National Association for Healthcare Quality.

To learn more about the potential psychosocial benefits of wellness coaching. Although wellness coaching is increasing in popularity, there are few published outcome studies. In a single-cohort study design, 100 employees who completed the 12-week wellness coaching program were of a mean age of 42 years, 90% were women, and most were overweight or obese. Three areas of psychosocial functioning were assessed: quality of life (QOL; 5 domains and overall), depressive symptoms (Patient Health Questionnaire-9), and perceived stress level (Perceived Stress Scale-10). Participants were recruited from January 1, 2011, through December 31, 2011; data were collected up to July 31, 2012, and were analyzed from August 1, 2012, through October 31, 2013. These 100 wellness coaching completers exhibited significant improvements in all 5 domains of QOL and overall QOL (P<.0001), reduced their level of depressive symptoms (P<.0001), and reduced their perceived stress level (P<.001) after 12 weeks of in-person wellness coaching, and they maintained these improvements at the 24-week follow-up. In this single-arm cohort study (level 2b evidence), participating in wellness coaching was associated with improvement in 3 key areas of psychosocial functioning: QOL, mood, and perceived stress level. The results from this single prospective cohort study suggest that these areas of functioning improve after participating in wellness coaching; however, randomized clinical trials involving large samples of diverse individuals are needed to establish level 1 evidence for wellness coaching.

1994-01-01

Safety reporting from individual ongoing and completed clinical studies has demonstrated that famciclovir, the well-absorbed oral form of the antiherpesvirus agent penciclovir, has been well tolerated by more than 3,000 individuals worldwide. An integrated safety evaluation has been performed and includes over 1,600 patients from 11 completed, randomized, double-blind clinical trials and 2 open trials. The famciclovir population consisted of 816 herpes zoster patients (four trials), 409 patients with acute genital herpesvirus infections (seven trials), and 382 patients from two genital herpes suppression studies. Overall, the famciclovir-treated patient population was 57.7% female and ranged in age from 15 to 102 years (mean, 42.6 years), with 31.2% aged 50 years or more and 15.7% aged 65 years or more. The mean duration of exposure to famciclovir was 28.8 days (5.8 days excluding suppression studies). The total daily doses ranged from 125 mg to 2.25 g. The most common adverse experiences reported as related to study medication (famciclovir and placebo) were headache, nausea, and diarrhea. The frequencies of adverse experiences and laboratory abnormalities (hematology, clinical chemistry, and urinalysis parameters) were similar in both famciclovir and placebo recipients. Thus, safety data from the analysis of 13 completed clinical studies demonstrate that famciclovir is tolerated well by patients with either herpes zoster or genital and has a safety profile comparable to that of placebo.

This study uses data from a 2003-4 cross sectional supplemental survey of respondents to the longitudinal Health and Retirement Study (HRS) who had been diagnosed with diabetes mellitus to assess effects of education on health and mechanisms underlying the relationship. The supplemental survey provides rich detail on use of personal health care services (e.g., adherence to guidelines for diabetes care) and personal attributes which are plausibly largely time invariant and systematically related to years of schooling completed, including time preference, self-control, and self-confidence. Educational attainment, as measured by years of schooling completed, is systematically and positively related to time to onset of diabetes, and conditional on having been diagnosed with this disease on health outcomes, variables related to efficiency in health production, as well as use of diabetes specialists. However, the marginal effects of increasing educational attainment by a year are uniformly small. Accounting for other factors, including child health and child socioeconomic status which could affect years of schooling completed and adult health, adult cognition, income, and health insurance, and personal attributes from the supplemental survey, marginal effects of educational attainment tend to be lower than when these other factors are not included in the analysis, but they tend to remain statistically significant at conventional levels.

Clinical and molecular approaches to well differentiated and dedifferentiated liposarcoma.

Crago, Aimee M; Singer, Samuel

Liposarcoma, a rare disease, is classified into five histologic subtypes. These include well differentiated liposarcoma (WDLS) and dedifferentiated liposarcoma (DDLS), both characterized by chromosome 12q13-15 amplification. This review will focus on the clinical management of WDLS and DDLS and examine recent molecular studies that have the potential to affect clinical management. Outcome of patients with WDLS and DDLS depends on completeness of surgical resection as well as tumor location and histologic subtype. Risk of recurrence is high for patients with dedifferentiated histology or retroperitoneal location. We now understand that surgical outcomes are poor for patients with rapidly growing or incompletely resectable tumors, so these patients should be managed nonoperatively. Radiation and chemotherapy have low response rates in WDLS and DDLS, but novel agents targeted at chromosome 12 gene products MDM2 and CDK4 have shown promise in preclinical studies and are being tested in clinical trials. Cell line, tissue microarray, and genomic analyses have identified additional targets including ZIC1, TOP2A, AURKA, and IGF-1R, which could form the basis of future therapies. Although complete surgical resection is currently the most effective treatment for WDLS and DDLS, the majority of patients with retroperitoneal liposarcoma will eventually have recurrence and die of disease. It is hoped that a multimodality approach, which incorporates targeted therapies and complete surgical resection, will significantly improve patient outcomes.

Completable scheduling: An integrated approach to planning and scheduling

The planning problem has traditionally been treated separately from the scheduling problem. However, as more realistic domains are tackled, it becomes evident that the problem of deciding on an ordered set of tasks to achieve a set of goals cannot be treated independently of the problem of actually allocating resources to the tasks. Doing so would result in losing the robustness and flexibility needed to deal with imperfectly modeled domains. Completable scheduling is an approach which integrates the two problems by allowing an a priori planning module to defer particular planning decisions, and consequently the associated scheduling decisions, until execution time. This allows a completable scheduling system to maximize plan flexibility by allowing runtime information to be taken into consideration when making planning and scheduling decision. Furthermore, through the criteria of achievability placed on deferred decision, a completable scheduling system is able to retain much of the goal-directedness and guarantees of achievement afforded by a priori planning. The completable scheduling approach is further enhanced by the use of contingent explanation-based learning, which enables a completable scheduling system to learn general completable plans from example and improve its performance through experience. Initial experimental results show that completable scheduling outperforms classical scheduling as well as pure reactive scheduling in a simple scheduling domain.

The overhead of interprocessor communication is a major factor in limiting the performance of parallel computer systems. The complete exchange is the severest communication pattern in that it requires each processor to send a distinct message to every other processor. This pattern is at the heart of many important parallel applications. On hypercubes, multiphase complete exchange has been developed and shown to provide optimal performance over varying message sizes. Most commercial multicomputer systems do not have a hypercube interconnect. However, they use special purpose hardware and dedicated communication processors to achieve very high performance communication and can be made to emulate the hypercube quite well. Multiphase complete exchange has been implemented on three contemporary parallel architectures: the Intel Paragon, IBM SP2 and Meiko CS-2. The essential features of these machines are described and their basic interprocessor communication overheads are discussed. The performance of multiphase complete exchange is evaluated on each machine. It is shown that the theoretical ideas developed for hypercubes are also applicable in practice to these machines and that multiphase complete exchange can lead to major savings in execution time over traditional solutions.

On the optimization of Gaussian basis sets

A new procedure for the optimization of the exponents, αj, of Gaussian basis functions, Ylm(ϑ,φ)rle-αjr2, is proposed and evaluated. The direct optimization of the exponents is hindered by the very strong coupling between these nonlinear variational parameters. However, expansion of the logarithms of the exponents in the orthonormal Legendre polynomials, Pk, of the index, j: ln αj=∑k=0kmaxAkPk((2j-2)/(Nprim-1)-1), yields a new set of well-conditioned parameters, Ak, and a complete sequence of well-conditioned exponent optimizations proceeding from the even-tempered basis set (kmax=1) to a fully optimized basis set (kmax=Nprim-1). The error relative to the exact numerical self-consistent field limit for a six-term expansion is consistently no more than 25% larger than the error for the completely optimized basis set. Thus, there is no need to optimize more than six well-conditioned variational parameters, even for the largest sets of Gaussian primitives.

Herein, a micro-structured electrode design has been developed via a modified phase-inversion method. A thin electrolyte integrated with a highly porous anode scaffold has been fabricated in a single-step process and developed into a complete fuel cell for direct methane (CH4) utilisation. A continuous and well-dispersed layer of copper-ceria (Cu-CeO2) was incorporated inside the micro-channels of the anode scaffold. A complete cell was investigated for direct CH4 utilisation. The well-organised micro-channels and nano-structured Cu-CeO2 anode contributed to an increase in electrochemical reaction sites that promoted charge-transfer as well as facilitating gaseous fuel distribution, resulting in outstanding performances. Excellent electrochemical performances have been achieved in both hydrogen (H2) and CH4 operation. The power density of 0.16 Wcm-2 at 750 °C with dry CH4 as fuel is one of the highest ever reported values for similar anode materials.

Objectives: To assess the level and accuracy of public understanding of human papillomavirus (HPV) in the United Kingdom. Methods: Women attending a well woman clinic were asked to complete a questionnaire assessing HPV awareness and specific knowledge about the virus. Results: Questionnaires were completed by 1032 women, of whom 30% had heard of HPV. Older women, non-smokers, and those with a history of candida, genital warts, or an abnormal smear result were more likely to have heard of HPV. Even among those who had heard of HPV, knowledge was generally poor, and fewer than half were aware of the link with cervical cancer. There was also confusion about whether condoms or oral contraceptives could protect against HPV infection. Conclusions: In this relatively well educated sample, awareness and knowledge of HPV were poor. Public education is urgently needed so that women participating in cervical cancer screening are fully informed about the meaning of their results, especially if HPV testing is soon to be introduced.

Transformations on quantum states form a basic building block of every quantum information system. From photonic polarization to two-level atoms, complete sets of quantum gates for a variety of qubit systems are well known. For multilevel quantum systems beyond qubits, the situation is more challenging. The orbital angular momentum modes of photons comprise one such high-dimensional system for which generation and measurement techniques are well studied. However, arbitrary transformations for such quantum states are not known. Here we experimentally demonstrate a four-dimensional generalization of the Pauli X gate and all of its integer powers on single photons carrying orbital angular momentum. Together with the well-known Z gate, this forms the first complete set of high-dimensional quantum gates implemented experimentally. The concept of the X gate is based on independent access to quantum states with different parities and can thus be generalized to other photonic degrees of freedom and potentially also to other quantum systems.

The Jupiter fields consist of a number of separate Rotliegendes gas reservoirs located approximately 90 miles off the Lincolnshire coast of the UK. The fields that make up Jupiter are Ganymede, Calisto, Europa, Sinope, and Thebe. Originally discovered in 1970, initial appraisal wells indicated poor reservoir properties and low deliverabilities. Development was postponed until a reappraisal of the area in the 1990`s indicated significant upside potential. The initial phase of the Jupiter development plan called for development of Ganymede and Calisto fields, with subsequent phases tying in Europa and Thebe. Initial development planning indicated a need for high field deliverabilitymore » at low capital cost to meet economic targets. A small number of high-rate-potential wells were to be used to deplete the reservoir. Ganymede would be developed by use of a 10-slot platform and Calisto would be developed subsea and tied back to the Ganymede platform. The paper discusses the reservoir, formation assessment, productivity design, drilling design, screen installation, and completion performance.« less

The current project examined the impact of caregiving and caregiving-work conflict on employees' well-being. A sequential explanatory mixed-methods design (QUAN→qual) was utilized, and a total of 880 employees from a large health-care plan employer completed an online survey. Forty-five caregivers who completed the survey also participated in one of the five focus groups held 1 to 2 months later. Employed caregivers were significantly ( p < .05) more likely to indicate poorer physical and mental health than noncaregivers; among caregivers ( n = 370), caregiving-work conflict emerged as the most significant predictor of well-being and fully mediated the empirical relationship between burden and well-being. The focus group findings complemented the quantitative results; many of the challenges employed caregivers experience stem from their ability or inability to effectively balance their employment and caregiving roles. The results suggest the need to focus on caregiving-work conflict when constructing new or translating existing evidence-based caregiver interventions.

Management of tracheal chondrosarcoma almost completely obstructing the airway: a case report.

Primary malignant tracheal tumors account for only 0.2 % of all malignancies of the respiratory tract. Tracheal chondrosarcoma is a rare condition and only 17 cases have been described in the literature from 1965 to date. Herein we report the very unusual case of a patient with a tracheal chondrosarcoma, electively treated by curative surgery despite the virtually complete obstruction of the airway. We present the case of a 79-year old Caucasian man with long-lasting wheezing misdiagnosed as asthma and affected by a tracheal chondrosarcoma almost completely obstructing the airway. Videobronchoscopy and imaging investigations revealed a well-circumscribed mass arising from the cartilaginous rings of the cervical trachea with a posterior residual respiratory space of about 1 mm. Because of the mobility and flaccidity of the uninvolved pars membranacea, the tiny respiratory space slightly expanded during inspiration and expiration allowing the patient to be treated without an essential emergency procedure. Standard tracheal intubation was impossible. Rigid bronchoscopy enabled placement of a small tracheal tube distally to the tumor. Successful cervical tracheal resection and reconstruction was then performed, achieving complete tumor excision. Histologically, the mass was characterized as a low-grade tracheal chondrosarcoma. Videobronchoscopy performed 9 months after surgery showed a wide, well healed tracheal anastomosis. Ten months after surgery, the patient is alive and disease free. Complete surgical resection is the treatment of choice for tracheal chondrosarcoma. Rigid bronchoscopy is an essential tool for diagnostic and therapeutic purposes. It allows the palliative maneuvers for obstruction relief but also, in resectable patients, the intraoperative safe and straightforward management of the obstructed airway.

Based on a review of 20 well-documented cases reported in the English literature between 1968 and 2008, herpes zoster ophthalmicus (HZO) may rarely be associated with complete unilateral ophthalmoplegia, defined here as impaired ocular ductions in all 4 directions within 3 months of onset of manifestations of HZO. Ophthalmoplegia occurred equally in immune-competent and immune-incompetent individuals. HZO preceded ophthalmoplegia in 75% by a mean interval of 9.5 days and a range of 2 to 60 days, occurred simultaneously with ophthalmoplegia in 20%, and followed by 2 days the onset of ophthalmoplegia in only 5%. Concurrent conjunctival inflammation, keratitis, or anterior uveitis was present in 90%. Lumbar puncture showed features of aseptic meningitis in 88%, slightly more than the 40%-50% found in patients with HZO without ophthalmoplegia. On orbit/brain imaging, abnormal enlargement of the extraocular muscles was present in 33%, and orbital soft tissue swelling was present in 17%. Enhancement of ocular motor cranial nerves was not reported. Complete or near-complete resolution of ophthalmoplegia occurred in 65% within a range of 2 weeks to 1.5 years (mean 4.4 months). A single autopsy report described granulomatous angiitis of the meninges and large vessels in the anterior cerebral circulation, as well as periaxial infarction in the optic nerve, pons, and medulla but without viral inclusion bodies or antigen. Unsettled issues are whether the pathogenesis is direct viral invasion or an immune reaction to the virus, whether the impaired ocular ductions are based on myopathic or neuropathic injury, whether there are predisposing factors to the combination of HZO and complete ophthalmoplegia, and whether treatment is effective.

Frequent homozygosity in both mature and immature ovarian teratomas: a shared genetic basis of tumorigenesis.

2017-10-01

Although homozygosity is well documented in mature teratomas, the genetic zygosity of ovarian immature teratomas and mixed germ cell tumors is less well studied. Ten cases of mature cystic teratomas, eleven cases of grade 2 or 3 immature teratomas, and seven cases of mixed germ cell tumors with an immature teratoma component were investigated by short tandem repeat genotyping to interrogate their genetic zygosity. DNA genotyping was informative in eight mature teratomas, seven immature teratomas and six cases of mixed germ cell tumors. Out of the eight mature teratomas, five cases showed partial or complete homozygosity (63%) with two cases demonstrating complete homozygosity (25%). Of the immature teratomas, six cases showed partial or complete homozygosity (86%) with two cases demonstrating complete homozygosity (29%). For the mixed germ cell tumors, two cases showed partial homozygosity (33%) and none displayed complete homozygosity. Long-term clinical follow-up was available for five immature teratomas (mean follow-up 110 months) and five mixed germ cell tumors (mean follow-up 66 months). None of the five patients with pure immature teratoma had a recurrence; in contrast, four out of five mixed ovarian germ cell tumors recurred between 4 months to 8 years (P=0.048). In conclusion, both immature and mature teratomas harbor frequent genetic homozygosity suggesting a common cellular origin involving germ cells at the same developmental stage. The difference in the rate of homozygosity and tumor recurrence between pure immature teratomas and mixed germ cell tumors suggests that the two entities may involve different pathogenetic pathways and likely pursue different biological behaviors.

Water-quality assessment of part of the upper Mississippi River basin, Minnesota and Wisconsin - Volatile organic compounds in surface and ground water, 1978-94

Examination of water-quality data from widely distributed sampling networks of river sites and wells in the study area led to the following conclusions: 1) trace amounts of chlorinated VOC's were detected sporadically in waters of the Mississippi, Minnesota, St. Croix, and Vermillion Rivers; 2) benzene, ethylbenzene, toluene, and meta+paraxylene were detected sporadically in waters sampled from the chain of lakes used as the municipal supply for St. Paul, Minnesota; 3) the target VOC's were detected in less than five percent of ground-water samples at relatively low concentrations, generally near detection limits which ranged from 1 to 5 micrograms per liter; 4) VOC's were generally detected at similar frequencies, but at higher concentrations, in water samples from wells completed in sand and gravel aquifers than in water samples from wells completed in bedrock aquifers; 5) VOC's were most commonly detected in ground water in the vicinity of identifiable emission sites of VOC's, such as landfills, dumps, or major industries; 6) trichloroethene, a commonly used degreasing agent in dry cleaning, metal cleaning and cleaning septic lines, was the most frequently detected target VOC in ground water sampled from wells completed in both sand and gravel and bedrock aquifers; 7) wells producing water with detectable concentrations of the target VOC's tended to be shallower than wells producing water with no detectable concentrations of those compounds, but the differences in well depths were not statistically significant at a 95 percent confidence level; and 8) chlorination of water substantially increased the frequency of detection of trihalomethane compounds. The low frequencies of detection of the target VOC's and THM's in surface and ground water sampled from widely distributed sampling networks in the study area indicate that, although there are thousands of sites which can potentially emit these compounds to water, soil, and the atmosphere, these compounds have not had a widespread measurable effect on the quality of surface and ground water in the study area.

Water resources in the Wardensville Area, Hardy County, West Virginia, October 2003-May 2004

Communities within the Valley and Ridge Physiographic Province of West Virginia are concerned about the availability and sustainability of their water supplies. The water resources of the Wardensville area of West Virginia were investigated and data sources were reviewed that will be useful in similar resource assessments elsewhere in the region. Estimates of long-term average discharge of the Cacapon River, Waites Run, and Trout Run are 170, 21, and 78 cubic feet per second, respectively. Average flow from Wardensville Spring during the study was determined to be 0.265 cubic feet per second, and the apparent age of this water was about 20 years. Increases in springflow and drops in temperature of the water during significant winter runoff events suggest that Wardensville Spring may be under the influence of surface runoff at such times. About 80 total coliform colonies per 100 milliliters (mL) of water were found in the spring, but less than 1 colony per 100 mL of water was fecal coliform, and their source is unknown. A well completed during the study in the Marcellus Shale near the contact with the Oriskany Sandstone is capable of yielding 60 gallons per minute, and water produced from the well has an apparent age of 50 years. Iron and manganese concentrations in the well (1,680 and 114 micrograms per liter, respectively) exceeded the U.S. Environmental Protection Agency secondary maximum contaminant levels. It is likely that a well drilled about 130 feet from Wardensville Spring is hydraulically connected to the spring because pumping at the time of well completion induced drawdown at the spring. About 20 total coliform colonies per 100 mL of water were found in that well, but fecal coliform counts were less than 1 colony per 100 mL of water. Transmissivity values of the aquifer as determined at two wells completed in the Marcellus Shale near the contact with the Oriskany Sandstone on opposite sides of Anderson Ridge are 200 and 400 feet squared per day.

There are no previous studies about the association of childhood bullying behavior with later suicide attempts and completed suicides among both sexes. The aim was to study associations between childhood bullying behaviors at age 8 years and suicide attempts and completed suicides up to age 25 years in a large representative population-based birth cohort. The sample includes 5,302 Finnish children born in 1981. Information about bullying was gathered at age 8 years from self-report, as well as parent and teacher reports. Information about suicide attempts requiring hospital admission and completed suicides was gathered from three different Finnish registries until the study participants were 25 years old. Regression analyses were conducted to determine whether children who experience childhood bullying behaviors are at risk for later suicide attempts and completed suicides after controlling for baseline conduct and depression symptoms. The association between bullying behavior at age 8 years and later suicide attempts and completed suicides varies by sex. Among boys, frequent bullying and victimization are associated with later suicide attempts and completed suicides but not after controlling for conduct and depression symptoms; frequent victimization among girls is associated with later suicide attempts and completed suicides, even after controlling for conduct and depression symptoms. When examining childhood bullying behavior as a risk factor for later suicide attempts and completed suicides, each sex has a different risk profile.

We investigate the dynamics of the eigenstate of an infinite well under an abrupt shift of the well’s wall. It is shown that when the shift is small compared to the initial well’s dimensions, the short-time behavior changes from the well-known t3/2 behavior to t1/2. It is also shown that the complete dynamical picture converges to a universal function, which has fractal structure with dimensionality D=1.25.

Groundwater quality and water-well characteristics in the Kickapoo Tribe of Oklahoma Jurisdictional Area, central Oklahoma, 1948--2011

In 2012, the U.S. Geological Survey, in cooperation with the Kickapoo Tribe of Oklahoma, compiled historical groundwater-quality data collected from 1948 to 2011 and water-well completion information in parts of Lincoln, Oklahoma, and Pottawatomie Counties in central Oklahoma to support the development of a comprehensive water-management plan for the Tribe’s jurisdictional area. In this study, water-quality data from 155 water wells, collected from 1948 to 2011, were retrieved from the U.S. Geological Survey National Water Information System database; these data include measurements of pH, specific conductance, and hardness and concentrations of the major ions, trace elements, and radionuclides that have Maximum Contaminant Levels or Secondary Maximum Contaminant Levels in public drinking-water supplies. Information about well characteristics includes ranges of well yield and well depth of private water wells in the study area and was compiled from the Oklahoma Water Resources Board Multi-Purpose Well Completion Report database. This report also shows depth to water from land surface by using shaded 30-foot contours that were created by using a geographic information system and spatial layers of a 2009 potentiometric surface (groundwater elevation) and land-surface elevation. Wells in the study area produce water from the North Canadian River alluvial and terrace aquifers, the underlying Garber Sandstone and Wellington Formation that compose the Garber–Wellington aquifer, and the Chase, Council Grove, and Admire Groups. Water quality varies substantially between the alluvial and terrace aquifers and bedrock aquifers in the study area. Water from the alluvial aquifer has relatively high concentrations of dissolved solids and generally is used for livestock only, whereas water from the terrace aquifer has low concentrations of dissolved solids and is used extensively by households in the study area. Water from the bedrock aquifer also is used extensively by households but may have high concentrations of trace elements, including uranium, in some areas where groundwater pH is above 8.0. Well yields vary and are dependent on aquifer characteristics and well-completion practices. Well yields in the unconsolidated alluvial and terrace aquifers generally are higher than yields from bedrock aquifers but are limited by the thickness and extent of these river deposits. Well yields in the alluvium and terrace aquifers commonly range from 50 to 150 gallons per minute and may exceed 300 gallons per minute, whereas well yields in the bedrock aquifers commonly range from 25 to 50 gallons per minute in the western one-third of study area (Oklahoma County) and generally less than 25 gallons per minute in the eastern two-thirds of the study area (Lincoln and Pottawatomie Counties).

We examined whether intra-family discrepancies in perceptions of the adolescent’s competence and independence were associated with autonomy and also well-being for adolescents and parents. The latent discrepancy model was used to examine the ways that mothers and fathers consistently differed from their adolescent across measures of independence and competence regarding type 1 diabetes, a stressful context for families. One-hundred and eighty-five mothers, fathers, and adolescents (M age= 12.5 SD= 1.3) completed measures of the adolescent’s independence in completing diabetes tasks, problems with diabetes management, adherence to the medical regimen, measures of well-being, and metabolic control. The latent discrepancy model was conducted via structural equation modeling that generated latent discrepancies from the adolescent for mothers and fathers. Both mothers and fathers viewed the adolescent’s competence more negatively than did the adolescent. These discrepancies related to more parental encouragement of independence and adolescent autonomy, but also poorer metabolic control, and poorer parental psychosocial well-being. The results are interpreted within a developmental perspective that views discrepancies as reflecting normative developmental processes of autonomy, but associated with disruptions in well-being in the short term.

Limited research has been conducted concerning nurses' work stress in developing countries, such as Nigeria. Accordingly, it is not clear whether work interventions for improving nurses' well-being in these countries can be based on work stress models that are developed in Western countries, such as the job demand control support model, as well as on empirical findings of job demand control support research. Nurses from Nurses Across the Borders Nigeria were invited to complete an online questionnaire containing validated scales; 210 questionnaires were fully completed and analysed. Multiple regression analysis was used to test the hypotheses. Emotional exhaustion was higher for nurses who experienced high demands and low supervisor support. Active learning occurred when nurses worked under conditions of high control and high supervisor support. The findings suggest that the job demand control support model is applicable in a Nigerian nursing situation; the model indicates which occupational stressors contribute to poor well-being in Nigerian nurses and which work characteristics may boost nurses' active learning. Job (re)design interventions can enhance nurses' well-being and learning by guarding nurses' job demands, and stimulating job control and supervisor support. © 2016 John Wiley & Sons Ltd.

Quantum dynamics of a two-state system induced by a chirped zero-area pulse

It is well known that area pulses make Rabi oscillation and chirped pulses in the adiabatic interaction regime induce complete population inversion of a two-state system. Here we show that chirped zero-area pulses could engineer an interplay between the adiabatic evolution and Rabi-like rotations. In a proof-of-principle experiment utilizing spectral chirping of femtosecond laser pulses with a resonant spectral hole, we demonstrate that the chirped zero-area pulses could induce, for example, complete population inversion and return of the cold rubidium atom two-state system. Experimental result agrees well with the theoretically considered overall dynamics, which could be approximately modeled to a Ramsey-like three-pulse interaction, where the x and z rotations are driven by the hole and the main pulse, respectively.

Single mothers are at increased risk of psychosocial disadvantage, social isolation and physical and mental health difficulties. The authors present (1) the results of group cohesion assessments completed by mothers participating in a trial of community-based support/education groups, and (2) assessments of the association between group cohesion ratings and intervention outcomes of maternal self-evaluations of well-being (mood, self-esteem, and social support) and parenting. Mothers participating in groups completed the Group Atmosphere Scale, a measure of group cohesion, post-group. Overall, most participants provided strong ratings of group cohesion. Significant associations were found between group cohesion and specific positive outcomes. This suggests a positive association between group cohesion and mood, self-esteem, social support, and parenting, in this trial.

2017-11-01

On a daily basis, healthcare providers, especially those dealing with terminally ill patients, such as hospice workers, witness how advance directives help ensure the wishes of patients. They also witness the deleterious consequences when patients fail to document the care they desire at their end of life. To the best of our knowledge there are no data concerning the prevalence of advance directives among hospice healthcare providers. We therefore explored the prevalence and factors influencing completion rates in a survey of hospice healthcare providers. Surveys that included 32 items to explore completion rates, as well as barriers, knowledge, and demographics, were e-mailed to 2097 healthcare providers, including employees and volunteers, at a nonprofit hospice. Of 890 respondents, 44% reported having completed an advance directive. Ethnicity, age, relationship status, and perceived knowledge were all significant factors influencing the completion rates, whereas years of experience or working directly with patients had no effect. Procrastination, fear of the subject, and costs were common reasons reported as barriers. Upon completion of the survey, 43% said they will now complete an advance directive, and 45% will talk to patients and families about their wishes. The majority of hospice healthcare providers have not completed an advance directive. These results are very similar to those for other healthcare providers treating patients with terminal diseases, specifically oncologists. Because, at completion, 43% said that they would now complete an advance directive, such a survey of healthcare providers may help increase completion rates. Copyright © 2017 Elsevier Inc.

Investigation of complete and incomplete fusion in the 7Li+124Sn reaction near Coulomb barrier energies

NASA Astrophysics Data System (ADS)

Parkar, V. V.; Sharma, Sushil K.; Palit, R.; Upadhyaya, S.; Shrivastava, A.; Pandit, S. K.; Mahata, K.; Jha, V.; Santra, S.; Ramachandran, K.; Nag, T. N.; Rath, P. K.; Kanagalekar, Bhushan; Trivedi, T.

2018-01-01

The complete and incomplete fusion cross sections for the 7Li+124Sn reaction were measured using online and offline characteristic γ -ray detection techniques. The complete fusion (CF) cross sections at energies above the Coulomb barrier were found to be suppressed by ˜26 % compared to the coupled channel calculations. This suppression observed in complete fusion cross sections is found to be commensurate with the measured total incomplete fusion (ICF) cross sections. There is a distinct feature observed in the ICF cross sections, i.e., t capture is found to be dominant compared to α capture at all the measured energies. A simultaneous explanation of complete, incomplete, and total fusion (TF) data was also obtained from the calculations based on the continuum discretized coupled channel method with short range imaginary potentials. The cross section ratios of CF/TF and ICF/TF obtained from the data as well as the calculations showed the dominance of ICF at below-barrier energies and CF at above-barrier energies.

The Complete Sequence of a Human Parainfluenzavirus 4 Genome

Yea, Carmen; Cheung, Rose; Collins, Carol; Adachi, Dena; Nishikawa, John; Tellier, Raymond

2009-01-01

Although the human parainfluenza virus 4 (HPIV4) has been known for a long time, its genome, alone among the human paramyxoviruses, has not been completely sequenced to date. In this study we obtained the first complete genomic sequence of HPIV4 from a clinical isolate named SKPIV4 obtained at the Hospital for Sick Children in Toronto (Ontario, Canada). The coding regions for the N, P/V, M, F and HN proteins show very high identities (95% to 97%) with previously available partial sequences for HPIV4B. The sequence for the L protein and the non-coding regions represent new information. A surprising feature of the genome is its length, more than 17 kb, making it the longest genome within the genus Rubulavirus, although the length is well within the known range of 15 kb to 19 kb for the subfamily Paramyxovirinae. The availability of a complete genomic sequence will facilitate investigations on a respiratory virus that is still not completely characterized. PMID:21994536

Lean Six Sigma (LSS) process analysis can be used to increase completeness of discharge summary reports used as a critical communication tool when a patient transitions between levels of care. The authors used the LSS methodology as an intervention to improve systems process. Over the course of the project, 8 required elements were analyzed in the discharge paperwork. The authors analyzed the discharge paperwork of patients (42 patients preintervention and 143 patients postintervention) of a comprehensive integrated inpatient rehabilitation program (CIIRP). Prior to this LSS project, 61.8% of required discharge elements were present. The intervention improved the completeness to 94.2% of the required elements. The percentage of charts that were 100% complete increased from 11.9% to 67.8%. LSS is a well-established process improvement methodology that can be used to make significant improvements in complex health care workflow issues. Specifically, the completeness of discharge documentation required for transition of care to CIIRP can be improved.

Human health risk assessment of air emissions from development of unconventional natural gas resources.

McKenzie, Lisa M; Witter, Roxana Z; Newman, Lee S; Adgate, John L

2012-05-01

Technological advances (e.g. directional drilling, hydraulic fracturing), have led to increases in unconventional natural gas development (NGD), raising questions about health impacts. We estimated health risks for exposures to air emissions from a NGD project in Garfield County, Colorado with the objective of supporting risk prevention recommendations in a health impact assessment (HIA). We used EPA guidance to estimate chronic and subchronic non-cancer hazard indices and cancer risks from exposure to hydrocarbons for two populations: (1) residents living >½ mile from wells and (2) residents living ≤ ½ mile from wells. Residents living ≤ ½ mile from wells are at greater risk for health effects from NGD than are residents living >½ mile from wells. Subchronic exposures to air pollutants during well completion activities present the greatest potential for health effects. The subchronic non-cancer hazard index (HI) of 5 for residents ≤ ½ mile from wells was driven primarily by exposure to trimethylbenzenes, xylenes, and aliphatic hydrocarbons. Chronic HIs were 1 and 0.4. for residents ≤ ½ mile from wells and >½ mile from wells, respectively. Cumulative cancer risks were 10 in a million and 6 in a million for residents living ≤ ½ mile and >½ mile from wells, respectively, with benzene as the major contributor to the risk. Risk assessment can be used in HIAs to direct health risk prevention strategies. Risk management approaches should focus on reducing exposures to emissions during well completions. These preliminary results indicate that health effects resulting from air emissions during unconventional NGD warrant further study. Prospective studies should focus on health effects associated with air pollution. Copyright © 2012 Elsevier B.V. All rights reserved.

We investigated the extent to which cognitive and noncognitive skills accounted for the measured links between participation in preschool intervention and high school completion, highest grade completed, and incarceration history in early adulthood. Using data from the Chicago Longitudinal Study, an on-going 20-year investigation of the effects of the school-based Child-Parent Center early intervention program for over 1,500 children, we assessed the contribution of school readiness and achievement test scores up to age 14 and remedial education as well as measures of social adjustment, motivation, educational expectations, problem behavior, and juvenile arrest to the estimated direct effect of preschool. Hierarchical regression analysis indicated that when assessed separately, cognitive factors accounted for 42% of the preschool effect on high school completion, 37% on highest grade completed, and 23% on incarceration history by age 24 while noncognitive factors accounted for, respectively, 36%, 45%, and 59%. Together, cognitive and noncognitive factors explained 46%, 51%, and 59% of the main effect of preschool participation. The set of cognitive skills made greater value-added contributions to educational attainment while noncognitive skills made greater value-added contributions to incarceration history. Our findings support the important role of test scores, school performance, and social and motivational factors in explaining the effect of preschool participation on economically important indicators of well-being.

Successful Multi-Leg Completion of KS-13 ML-1 & Increased Power Generation of Puna Geothermal Venture (PGV), Hawai'i

NASA Astrophysics Data System (ADS)

Drakos, P. S.; Spielman, P.; Peters, B.

2017-12-01

Located in the Puna district on the Big Island in Hawaii, Puna Geothermal Venture (PGV) is the only geothermal power plant in the state. PGV is comprised of two air-cooled power plants with a total generating capacity of 38 MW. Commercial operation commenced in 1993 and the project was acquired by Ormat in June 2004. Over the years, generation has increased by upgrading the plant through resource development and with the addition of a bottoming OEC (Ormat Energy Converter) in 2011. The geothermal reservoir at PGV is hosted within a step-over along the axis of the Kilauea Lower East Rift Zone (LERZ). Subsurface permeability at PGV is controlled by sub-vertical and rift-parallel fractures/faults and dike swarms which are the result of active tectonic dilation across the rift and shallow volcanic activity related to Kilauea. At PGV, the location and attitude of these fractures are well constrained at depth by drilling to be orientated at N63°E and dipping at 5° NW. These fractures are aligned en-echelon and form a major left-step along the rift axis which results in a localized zone of enhanced dilation. In 2016, a program was initiated to increase injection capacity and enthalpy in the PGV wellfield. Existing injection well KS-13 was selected as a candidate for re-drill based on a comprehensive resource model and reservoir modeling predictions. KS-13 ML1 was designed as a multi-leg completion from the existing KS-13 well, whereby the final completion is a forked well composed of the original wellbore and the newly completed second wellbore. The target area for the new multi-leg (ML) were large aperture, steeply dipping fractures associated with the 1955 eruptive fissure. Well KS-13 ML1 was drilled using PGV's Rig and a retrievable whipstock to mill a casing exit window. With the original wellbore temporarily plugged, a multi-rate water loss test was performed and an injectivity of 6 gpm/psi was measured. Following the removal of the whipstock ramp and packer from the original hole a 2nd test was performed on both KS-13+KS-13ML1. An injectivity of 7.2 gpm/psi was measured. KS-13 injection tripled from 600 kph prior to the redrill to 1800 kph afterward, and allowed an injection well that was cooling production to be shut in. This increased production enthalpy from 500 Btu/lbm to 580 Btu/lbm and available plant output increased 41% from 27 to 38 MW.

Ground-water level data for North Carolina, 1988-90

USGS Publications Warehouse

Strickland, A.G.; Coble, R.W.; Edwards, L.A.; Pope, B.F.

1992-01-01

Continuous and periodic water-level measurements were made in 59 key wells throughout North Carolina. Additional measurements were made in 112 supplementary wells completed in Coastal Plain aquifers of the State. Changes in groundwater storage are shown in 3-year and 10-year hydrographs of selected wells in the State. The water table in the shallow aquifers was higher throughout most of 1989 and early 1990 than in 1988, indicating that these aquifers were sufficiently recharged by precipitation to replenish the late 1987-88 deficit in groundwater storage. Water levels in the heavily pumped Coastal Plain aquifers declined as a result of water being withdrawn from aquifer storage. Record low water levels were measured in 8 to 13 wells completed in the Castle Hayne aquifer and in 6 of 8 wells in the Peedee aquifer; the maximum annual declines during 1988-90 averaged 3.3 and 1.6 ft/yr, respectively, for these two aquifers. All wells in the Black Creek, upper Cape Fear, and lower Cape Fear aquifers had record low water levels during 1988-90, with maximum annual declines averaging 9.0, 2.2, and 2.6 ft/yr, respectively. Water levels in two of three wells in the Yorktown aquifer did not show a general downward trend during 1988-90, although water levels declined in the third well, reaching a record low in 1990. The effects of water withdrawals from major pumping centers in the North Carolina Coastal Plain are shown in potentiometric-surface maps of the Black Creek and lower Cape Fear aquifers.

A clinical study to evaluate denture adhesive use in well-fitting dentures.

2012-02-01

The objective of this study was the assessment of retention and stability and functional benefits of denture adhesive applied to well-fitting and well-made dentures. This was a randomized, crossover study to compare two marketed denture adhesives (test cream, Super Poligrip® Free, and test strip, Super Poligrip® Comfort Seal Strips) and an unmarketed cream adhesive (GlaxoSmith Kline Consumer Healthcare) with no adhesive as the negative control. Thirty-six subjects completed the study. One hour after the application of denture adhesive, retention and stability were measured using the Kapur Index and maxillary incisal bite force. Two hours after application, functional tests were used to assess denture movement and peanut particle migration under the denture. Subjects also rated confidence, comfort, satisfaction with dentures, and denture wobble in conjunction with the functional tests. Denture adhesives significantly (p < 0.05) improved retention and stability of well-fitting dentures. Subjects experienced significantly (p < 0.05) fewer dislodgements while eating an apple after adhesive was applied to dentures. Significant (p < 0.05) increases in subjective ratings of confidence and comfort as well as decreases in denture wobble were associated with the use of adhesive. There was significant (p < 0.05) improvement in satisfaction ratings for cream adhesives. A single application of each denture adhesive was well tolerated. The results of this study provide evidence that use of Super Poligrip® denture adhesives can enhance aspects of performance of complete well-fitting dentures as well as provide increased comfort, confidence, and satisfaction with dentures. © 2011 by the American College of Prosthodontists.

Bacterial communities associated with hydraulic fracturing fluids in thermogenic natural gas wells in North Central Texas, USA.

PubMed

Struchtemeyer, Christopher G; Elshahed, Mostafa S

2012-07-01

Hydraulic fracturing is used to increase the permeability of shale gas formations and involves pumping large volumes of fluids into these formations. A portion of the frac fluid remains in the formation after the fracturing process is complete, which could potentially contribute to deleterious microbially induced processes in natural gas wells. Here, we report on the geochemical and microbiological properties of frac and flowback waters from two newly drilled natural gas wells in the Barnett Shale in North Central Texas. Most probable number studies showed that biocide treatments did not kill all the bacteria in the fracturing fluids. Pyrosequencing-based 16S rRNA diversity analyses indicated that the microbial communities in the flowback waters were less diverse and completely distinct from the communities in frac waters. These differences in frac and flowback water communities appeared to reflect changes in the geochemistry of fracturing fluids that occurred during the frac process. The flowback communities also appeared well adapted to survive biocide treatments and the anoxic conditions and high temperatures encountered in the Barnett Shale. © 2011 Federation of European Microbiological Societies.

Objective Depression has been found to impede several health outcomes among people living with HIV, but little research has examined whether depression treatment mitigates this influence. We assessed the impact of antidepressant therapy on measures of work, condom use, and psychosocial well-being among depressed HIV clients in Uganda. Methods Paired t-tests and McNemar tests were used to assess change in survey data collected from participants at initiation of antidepressant therapy (baseline) and 6 months later. Result Ninety-five participants completed the 6 month assessment, of whom 82 (86%) responded to treatment (defined as Patient Health Questionnaire-9 score < 5). Among study completers, work functioning improved significantly, as did measures of self-efficacy related to condom use and work (as well as general self efficacy) and internalized HIV stigma declined; however, actual engagement in work activity and consistent condom use did not show significant change. Similar findings were observed among treatment responders.

Depression has been found to impede several health outcomes among people living with HIV, but little research has examined whether depression treatment mitigates this influence. We assessed the impact of antidepressant therapy on measures of work, condom use, and psychosocial well-being among depressed HIV clients in Uganda. Paired t-tests and McNemar tests were used to assess change in survey data collected from participants at initiation of antidepressant therapy (baseline) and 6 months later. Ninety-five participants completed the 6-month assessment, of whom 82 (86%) responded to treatment (defined as Patient Health Questionnaire-9 score < 5). Among study completers, work functioning improved significantly, as did measures of self-efficacy related to condom use and work (as well as general self-efficacy), and internalized HIV stigma declined; however, actual engagement in work activity and consistent condom use did not show significant change. Similar findings were observed among treatment responders. Antidepressant treatment benefits functional capacity, psychological well-being, and cognitive intermediary factors that may be essential for behavioral change related to work and condom use, but supplementary therapeutic strategies may be needed to impact more direct behavioral change.

Parents and teachers of children with special needs face unique social-emotional challenges in carrying out their caregiving roles. Stress associated with these roles impacts parents' and special educators' health and well-being, as well as the quality of their parenting and teaching. No rigorous studies have assessed whether mindfulness training (MT) might be an effective strategy to reduce stress and cultivate well-being and positive caregiving in these adults. This randomized controlled study assessed the efficacy of a 5-week MT program for parents and educators of children with special needs. Participants receiving MT showed significant reductions in stress and anxiety and increased mindfulness, self-compassion, and personal growth at program completion and at 2 months follow-up in contrast to waiting-list controls. Relational competence also showed significant positive changes, with medium-to-large effect sizes noted on measures of empathic concern and forgiveness. MT significantly influenced caregiving competence specific to teaching. Mindfulness changes at program completion mediated outcomes at follow-up, suggesting its importance in maintaining emotional balance and facilitating well-being in parents and teachers of children with developmental challenges.

The Hubble Space Telescope Frontier Fields program (PI: J. Lotz) is a large Director's Discretionary program of 840 orbits, to obtain ultra-deep observations of six strong lensing clusters of galaxies, together with parallel deep blank fields, making use of the strong lensing amplification by these clusters of distant background galaxies to detect the faintest galaxies currently observable in the high-redshift universe. The first four of these clusters are now complete, namely Abell 2744, MACS J0416.1-2403, MACS J0717.5+3745 and MACS J1149.5+2223, with each of these having been observed over two epochs, to a total depth of 140 orbits on the main cluster and an associated parallel field, using ACS (F435W, F606W, F814W) and WFC3/IR (F105W, F125W, F140W, F160W). The remaining two clusters, Abell 370 and Abell S1063, are currently in progress, with the first epoch for each having been completed. Full sets of high-level science products have been generated for all these clusters by the team at STScI, including cumulative-depth v0.5 data releases during each epoch, as well as full-depth version 1.0 releases after the completion of each epoch. These products include all the full-depth distortion-corrected mosaics and associated products for each cluster, which are science-ready to facilitate the construction of lensing models as well as enabling a wide range of other science projects. Many improvements beyond default calibration for ACS and WFC3/IR are implemented in these data products, including corrections for persistence, time-variable sky, and low-level dark current residuals, as well as improvements in astrometric alignment to achieve milliarcsecond-level accuracy. The full set of resulting high-level science products are publicly delivered to the community via the Mikulski Archive for Space Telescopes (MAST) to enable the widest scientific use of these data, as well as ensuring a public legacy dataset of the highest possible quality that is of lasting value to the entire community.

A comparison of microseismicity induced by gel-proppant-and water-injected hydraulic fractures, Carthage Cotton Valley gas field, East Texas

DOE Office of Scientific and Technical Information (OSTI.GOV)

Rutledge, J. T.; Phillips, W. S.

In May and July, 1997, a consortia of operators and service companies conducted a series of hydraulic fracture imaging tests in the Carthage Cotton Valley gas field of East Texas (Walker, 1997). Microseismic data were collected and processed for six hydraulic fracture treatments in two wells (3 completion intervals per well) (Mayerhofer et al., 2000). One well was completed with gel-proppant treatments in which a viscous crosslink gel was injected to entrain high concentrations of sand proppant into formation. The second well was completed using treated water and very low proppant concentrations (waterfracs). Waterfracs have been shown to be justmore » as effective as the conventional gel-proppant treatments in Cotton Valley reservoirs, but at greatly reduced cost. Mayerhofer and Meehan (1998) suggest two possible reasons why waterfracs are successful: (1) Induced shear displacement along natural and hydraulic fractures results in self-propping (shear dilation enhanced by fracture branching, proppant and spalled rock fragments), and (2) Fracture extension and cleanup is easier to achieve with low-viscosity fluids. With improved source location precision and focal mechanism determination (fracture plane orientation and sense of slip), we have reexamined the Cotton Valley data, comparing the seismicity induced by water and gel-proppant treatments at common depth intervals. We have improved the location precision and computed focal mechanism of microearthquakes induced during a series of hydraulic fracture completions within the Cotton Valley formation of East Texas. Conventional gel-proppant treatments and treatments using treated water and very low proppant concentrations (waterfracs) were monitored. Waterfracs have been shown to be just as effective as the conventional gel-proppant treatments in Cotton Valley reservoirs, but at greatly reduced cost (Mayerhofer and Meehan, 1998). Comparison of the seismicity induced by the two treatment types show similar distributions of event locations and focal mechanisms for common depth intervals. We interpret the induced seismicity to be primarily controlled by the natural fracture geometry and independent of treatment design. By implication, we expect the effectiveness of shear-induced fracture propping to be independent of the treatment fluid in Cotton Valley reservoirs.« less

A Theoretical Investigation of Radial Lateral Wells with Shockwave Completion in Shale Gas Reservoirs

NASA Astrophysics Data System (ADS)

Shan, Jia

As its role in satisfying the energy demand of the U.S. and as a clean fuel has become more significant than ever, the shale gas production in the U.S. has gained increasing momentum over recent years. Thus, effective and environmentally friendly methods to extract shale gas are critical. Hydraulic fracturing has been proven to be efficient in the production of shale gas. However, environmental issues such as underground water contamination and high usage of water make this technology controversial. A potential technology to eliminate the environmental issues concerning water usage and contamination is to use blast fracturing, which uses explosives to create fractures. It can be further aided by HEGF and multi-pulse pressure loading technology, which causes less crushing effect near the wellbore and induces longer fractures. Radial drilling is another relatively new technology that can bypass damage zones due to drilling and create a larger drainage area through drilling horizontal wellbores. Blast fracturing and radial drilling both have the advantage of cost saving. The successful combination of blast fracturing and radial drilling has a great potential for improving U.S. shale gas production. An analytical productivity model was built in this study, considering linear flow from the reservoir rock to the fracture face, to analyze factors affecting shale gas production from radial lateral wells with shockwave completion. Based on the model analyses, the number of fractures per lateral is concluded to be the most effective factor controlling the productivity index of blast-fractured radial lateral wells. This model can be used for feasibility studies of replacing hydraulic fracturing by blast fracturing in shale gas well completions. Prediction of fracture geometry is recommended for future studies.

To determine the best method for decellularisation of aortic valve conduits (AVCs) that efficiently removes the cells while preserving the extracellular matrix (ECM) by examining the valvular and conduit sections separately. Sheep AVCs were decellularised by using three different protocols: detergent-based (1% SDS+1% SDC), detergent and enzyme-based (Triton+EDTA+RNase and DNase), and enzyme-based (Trypsin+RNase and DNase) methods. The efficacy of the decellularisation methods to completely remove the cells while preserving the ECM was evaluated by histological evaluation, scanning electron microscopy (SEM), hydroxyproline analysis, tensile test, and DAPI staining. The detergent-based method completely removed the cells and left the ECM and collagen content in the valve and conduit sections relatively well preserved. The detergent and enzyme-based protocol did not completely remove the cells, but left the collagen content in both sections well preserved. ECM deterioration was observed in the aortic valves (AVs), but the ultrastructure of the conduits was well preserved, with no media distortion. The enzyme-based protocol removed the cells relatively well; however, mild structural distortion and poor collagen content was observed in the AVs. Incomplete cell removal (better than that observed with the detergent and enzyme-based protocol), poor collagen preservation, and mild structural distortion were observed in conduits treated with the enzyme-based method. The results suggested that the detergent-based methods are the most effective protocols for cell removal and ECM preservation of AVCs. The AVCs treated with this detergent-based method may be excellent scaffolds for recellularisation. Copyright © 2014 Medical University of Bialystok. Published by Elsevier Urban & Partner Sp. z o.o.

Little is known about the quality of life (QOL) of young adults with cerebral palsy. This cross-sectional analysis compares the QOL of a cohort of young Australian adults with CP with a cohort of able-bodied peers to explore the relationship between QOL and impairments, functioning, and social participation. Young adults identified from the Victorian Cerebral Palsy Register were invited to complete a survey about QOL, gross motor function, independence in self-care, and social participation. QOL was assessed with the Quality of Life Instrument for Young Adults (YAQOL). A general population sample of young North American adults, who had completed the YAQOL was selected for comparison. Surveys and consent forms were completed by 335 young adults or their proxies, an overall participation rate of 63% of those located. The mean age of the study participants was 24.7 [s.d = 2.8] years; 51% were male and 49% female. Two hundred and seven (62%) of the 335 participants self-reported their QOL. When compared with the general population sample, self-reporting participants had similar QOL scores for the social relationship and environmental context domains (p > 0.05), while QOL scores were lower for the physical health, psychological well-being, and role function domains (p < 0.001). There was no association between psychological well-being and variables related to body structure and gross motor function in young adults with CP. Contrary to the assumption that young adults with severe CP have low psychosocial well-being, it is apparent that these individuals can have good psychosocial well-being regardless of their disability.

The Well London program - a cluster randomized trial of community engagement for improving health behaviors and mental wellbeing: baseline survey results

PubMed Central

2012-01-01

Background The Well London program used community engagement, complemented by changes to the physical and social neighborhood environment, to improve physical activity levels, healthy eating, and mental wellbeing in the most deprived communities in London. The effectiveness of Well London is being evaluated in a pair-matched cluster randomized trial (CRT). The baseline survey data are reported here. Methods The CRT involved 20 matched pairs of intervention and control communities (defined as UK census lower super output areas (LSOAs); ranked in the 11% most deprived LSOAs in London by the English Indices of Multiple Deprivation) across 20 London boroughs. The primary trial outcomes, sociodemographic information, and environmental neighbourhood characteristics were assessed in three quantitative components within the Well London CRT at baseline: a cross-sectional, interviewer-administered adult household survey; a self-completed, school-based adolescent questionnaire; a fieldworker completed neighborhood environmental audit. Baseline data collection occurred in 2008. Physical activity, healthy eating, and mental wellbeing were assessed using standardized, validated questionnaire tools. Multiple imputation was used to account for missing data in the outcomes and other variables in the adult and adolescent surveys. Results There were 4,107 adults and 1,214 adolescent respondents in the baseline surveys. The intervention and control areas were broadly comparable with respect to the primary outcomes and key sociodemographic characteristics. The environmental characteristics of the intervention and control neighborhoods were broadly similar. There was greater between-cluster variation in the primary outcomes in the adult population compared to the adolescent population. Levels of healthy eating, smoking, and self-reported anxiety/depression were similar in the Well London adult population and the national Health Survey for England. Levels of physical activity were higher in the Well London adult population but this is likely to be due to the different measurement tools used in the two surveys. Conclusions Randomization of social interventions such as Well London is acceptable and feasible and in this study the intervention and control arms are well-balanced with respect to the primary outcomes and key sociodemographic characteristics. The matched design has improved the statistical efficiency of the study amongst adults but less so amongst adolescents. Follow-up data collection will be completed 2012.

Damphousse, Sarah Joan

2016-01-01

Between January 29 and March 9, 2016, a total of 23 monitoring wells were properly abandoned-in-place at five KSC sites (OPF-1&2, OPF-3, RDG, SRB, and HSB). The total abandonment encompassed 489.06 linear feet. The wells abandoned were constructed of PVC with diameters ranging from 1-inch to 2-inches. The shallowest well abandoned was measured to be 11.6 ft bls (OPF) and the deepest well abandoned was documented to be 51.45 feet bls (HSB). All aboveground completions were removed and each area was re-graded and/or grouted to surface to match existing surroundings. All materials (concrete pads, well casings, etc.) were disposed of accordingly.

2011-01-01

The U.S. Geological Survey, in cooperation with the South Carolina Department of Health and Environmental Control (SCDHEC), is drilling a deep geologic test well at Hilton Head Island, S.C. The test well is scheduled to run between mid-March and early May 2011. When completed, the well will be about 1,000 feet deep. The purpose of this test well is to gain knowledge about the regional-scale Floridan aquifer, an important source of groundwater in the Hilton Head area. Also, cores obtained during drilling will enable geologists to study the last 60 million years of Earth history in this area.

Potentiometric Surfaces and Water-Level Trends in the Cockfield (Upper Claiborne) and Wilcox (Lower Wilcox) Aquifers of Southern and Northeastern Arkansas, 2009

USGS Publications Warehouse

Pugh, Aaron L.

2010-01-01

Eocene-age sand beds near the base of the Cockfield Formation of Claiborne Group constitute the aquifer known locally as the Cockfield aquifer. Upper-Paleocene age sand beds within the lower parts of the Wilcox Group constitute the aquifer known locally as the Wilcox aquifer. In 2005, reported water withdrawals from the Cockfield aquifer in Arkansas totaled 16.1 million gallons per day, while reported water withdrawals from the Wilcox aquifer in Arkansas totaled 27.0 million gallons per day. Major withdrawals from these units were for industrial and public water supplies with lesser but locally important withdrawals for commercial, domestic, and agricultural uses. During February 2009, 56 water-level measurements were made in wells completed in the Cockfield aquifer and 57 water-level measurements were made in wells completed in the Wilcox aquifer. The results from the 2009 water-level measurements are presented in potentiometric-surface maps and in combination with previous water-level measurements. Trends in water-level change over time within the two aquifers are investigated using water-level difference maps and well hydrographs. Water-level difference maps were constructed for each aquifer using the difference between depth to water measurements made in 2003 to 2009. Well hydrographs for each aquifer were constructed for wells with 20 or more years of historical water-level data. The hydrographs were evaluated individually using linear regression to calculate the annual rise or decline in water levels, and by aggregating the regression results by county and statistically summarizing for the range, mean, and median water-level change in each county. The 2009 potentiometric surface of the Cockfield aquifer map indicates the regional direction of groundwater flow generally towards the east and southeast, except in two areas of intense groundwater withdrawals that have developed into cones of depression. The lowest water-level altitude measured was 43 feet and the highest water-level altitude measured was 351 feet. A water-level difference map was constructed from 54 wells completed in the Cockfield aquifer within Arkansas. The largest rise in water level was 14.9 feet and the largest decline was 27.4 feet. Seven wells had a rise in water level, and the remaining 47 wells had a decline in water level. Hydrographs for 33 wells completed in the Cockfield aquifer were developed. Hydrographs indicate water-level changes in individual wells ranged from rises of 0.33 feet per year to declines of 1.21 feet per year over the 20-year period (1990-2009). County summaries of the linear regression analysis indicate Cleveland and Columbia Counties have mean annual rises. Arkansas, Ashley, Bradley, Calhoun, Chicot, Desha, Drew, Lincoln, and Union Counties have mean annual declines. The potentiometric surface for the Wilcox aquifer is presented using two maps, one for a southern area and another for a northeastern area, because of the absence of water-level data in the central part of the State. The direction of groundwater flow in the southern area is generally the east, except around two cones of depression and around two mounds of elevated water levels. Water-level altitudes in the southern area range from 147 feet to 400 feet. The direction of groundwater flow in the northeastern area is generally to the south and southeast except in an area of intense groundwater withdrawals that has altered the flow to a westerly direction. Two water-level difference maps were constructed using water-level altitudes measured in 2003 to 2009 from 53 wells completed in the Wilcox aquifer within southern and northeastern Arkansas. In the southern area the largest rise in water level was 16.0 feet and the largest decline was 17.7 feet. Eight wells in the southern area had rising water levels and the remaining five wells had declining water levels. In the northeastern area, the largest rise in water level was 1.3 feet and the larg

An update of hydrologic conditions and distribution of selected constituents in water, Snake River Plain aquifer and perched groundwater zones, Idaho National Laboratory, Idaho, emphasis 2006-08

USGS Publications Warehouse

Davis, Linda C.

2010-01-01

Since 1952, radiochemical and chemical wastewater discharged to infiltration ponds (also called percolation ponds), evaporation ponds, and disposal wells at the Idaho National Laboratory (INL) has affected water quality in the eastern Snake River Plain aquifer and perched groundwater zones underlying the INL. The U.S. Geological Survey, in cooperation with the U.S. Department of Energy, maintains groundwater monitoring networks at the INL to determine hydrologic trends, and to delineate the movement of radiochemical and chemical wastes in the aquifer and in perched groundwater zones. This report presents an analysis of water-level and water-quality data collected from aquifer and perched groundwater wells in the USGS groundwater monitoring networks during 2006-08. Water in the Snake River Plain aquifer primarily moves through fractures and interflow zones in basalt, generally flows southwestward, and eventually discharges at springs along the Snake River. The aquifer primarily is recharged from infiltration of irrigation water, infiltration of streamflow, groundwater inflow from adjoining mountain drainage basins, and infiltration of precipitation. From March-May 2005 to March-May 2008, water levels in wells generally remained constant or rose slightly in the southwestern corner of the INL. Water levels declined in the central and northern parts of the INL. The declines ranged from about 1 to 3 feet in the central part of the INL, to as much as 9 feet in the northern part of the INL. Water levels in perched groundwater wells around the Advanced Test Reactor Complex (ATRC) also declined. Detectable concentrations of radiochemical constituents in water samples from wells in the Snake River Plain aquifer at the INL generally decreased or remained constant during 2006-08. Decreases in concentrations were attributed to decreased rates of radioactive-waste disposal, radioactive decay, changes in waste-disposal methods, and dilution from recharge and underflow. In April or October 2008, reportable concentrations of tritium in groundwater ranged from 810 ? 70 to 8,570 ? 190 picocuries per liter (pCi/L), and the tritium plume extended south-southwestward in the general direction of groundwater flow. Tritium concentrations in water from wells completed in shallow perched groundwater at the ATRC were less than the reporting levels. Tritium concentrations in deep perched groundwater exceeded the reporting level in 11 wells during at least one sampling event during 2006-08 at the ATRC. Tritium concentrations from one or more zones in each well were reportable in water samples collected at various depths in six wells equipped with multi-level WestbayTM packer sampling systems. Concentrations of strontium-90 in water from 24 of 52 aquifer wells sampled during April or October 2008 exceeded the reporting level. Concentrations ranged from 2.2 ? 0.7 to 32.7 ? 1.2 pCi/L. Strontium-90 has not been detected within the eastern Snake River Plain aquifer beneath the ATRC partly because of the exclusive use of waste-disposal ponds and lined evaporation ponds rather than using the disposal well for radioactive-wastewater disposal at ATRC. At the ATRC, the strontium-90 concentration in water from one well completed in shallow perched groundwater was less than the reporting level. During at least one sampling event during 2006-08, concentrations of strontium-90 in water from nine wells completed in deep perched groundwater at the ATRC were greater than reporting levels. Concentrations ranged from 2.1?0.7 to 70.5?1.8 pCi/L. At the Idaho Nuclear Technology and Engineering Center (INTEC), the reporting level was exceeded in water from two wells completed in deep perched groundwater. During 2006-08, concentrations of cesium-137, plutonium-238, and plutonium-239, -240 (undivided), and americium-241 were less than the reporting level in water samples from all wells and all zones in wells equipped with multi-level WestbayTM packer sampling systems

Exercise and physical activity provide a wide range of health benefits for postmenopausal women, although the impact of maintained exercise participation on psychological well-being is unclear. An exploration of continued exercise participation in psychological well-being after a moderate-intensity exercise program in previously inactive postmenopausal women was therefore undertaken. : Twenty-three healthy sedentary postmenopausal women (age 56 +/- 4 years) were randomly assigned to two groups. All participants completed the Short Form-36, Hospital Anxiety and Depression Scale (HADS), and Health Anxiety Questionnaire (HAQ) and then began a 6-week walking program at 50% heart rate reserve defined by (.-)V(O(2)) treadmill testing. Post-intervention, all participants underwent (.-)V(O(2)) treadmill testing and questionnaires. Group 1 was then instructed to continue exercising, whereas group 2 was instructed to desist for an additional 6-week period. On completion of the 6-week follow-up, participants completed a final set of questionnaires. Participants performed 97% of the prescribed 15-hour (900 minute) exercise program (875.1 +/- 177.4 minutes) in an average of 26 +/- 5 sessions. Total HAQ (P = 0.001), health worry (P = 0.001), fear of illness (P = 0.037), reassurance seeking behavior (P = 0.037), SF-36 well-being (P = 0.037), total HADS (P = 0.019), and HADS depression (P = 0.015) improved significantly following the exercise program. At follow-up, group 1 had lower HADS anxiety (P = 0.013), total HADS (P = 0.02), total HAQ (P = 0.03), and HAQ interference with life (P = 0.03) and significantly higher SF-36 energy (P = 0.01) than group 2. Healthy postmenopausal women gain significant psychological benefit from moderate-intensity exercise. However, exercise participation must continue to maintain improvements in psychological well-being and quality of life.

El Paso County Geothermal Project at Fort Bliss. Final Project Report

DOE Office of Scientific and Technical Information (OSTI.GOV)

Lear, Jon; Bennett, Carlon; Lear, Dan

The El Paso County Geothermal Project at Fort Bliss was an effort to determine the scale and scope of geothermal resources previously identified on Fort Bliss’ McGregor Range in southern Otero County, New Mexico. The project was funded with a $5,000,000 grant to El Paso County from the U.S. Department of Energy (DOE) as part of the American Recovery and Reinvestment Act of 2009 and a $4,812,500 match provided by private sector partners. The project was administered through the DOE Golden Field Office to awardee El Paso County. The primary subcontractor to El Paso County and project Principal Investigator -more » Ruby Mountain Inc. (RMI) of Salt Lake City, Utah - assembled the project team consisting of Evergreen Clean Energy Management (ECEM) of Provo, Utah, and the Energy & Geoscience Institute at the University of Utah (EGI) in Salt Lake City, UT to complete the final phases of the project. The project formally began in May of 2010 and consisted of two preliminary phases of data collection and evaluation which culminated in the identification of a drilling site for a Resource Confirmation Well on McGregor Range. Well RMI 56-5 was drilled May and June 2013 to a depth of 3,030 ft. below ground level. A string of slotted 7 inch casing was set in 8.75 inch hole on bottom fill at 3,017 ft. to complete the well. The well was drilled using a technique called flooded reverse circulation, which is most common in mineral exploration. This technique produced an exceptionally large and complete cuttings record. An exciting development at the conclusion of drilling was the suspected discovery of a formation that has proven to be of exceptionally high permeability in three desalinization wells six miles to the south. Following drilling and preliminary testing and analysis, the project team has determined that the McGregor Range thermal anomaly is large and can probably support development in the tens of megawatts.« less

Meitner, Peter L.; Boruta, Mike

2006-01-01

A prototype of a new, internal combustion (IC) engine concept has been completed. The Nutating Engine features an internal disk nutating (wobbling) on a Z-shaped power shaft. The engine is exceedingly compact, and several times more power dense than any conventional (reciprocating or rotary) IC engine. This paper discusses lessons learned during the prototype engine's development and provides details of its construction. In addition, results of the initial performance tests of the various components, as well as the complete engine, are summarized.

This report documents the well-construction activities at the Y-12 Plant in Oak Ridge, Tennessee during 1989 and 1990. The well- construction program consisted of installing seventy-five monitoring wells. Geologists from ERCE (formally the Engineering, Design and Geosciences Group) and Martin Marietta Energy Systems (Energy Systems), supervised and documented well-construction activities and monitored for health and safety concerns. Sixty-seven monitoring wells were installed under the supervision of an ERCE geologist from March 1989 to September 1990. Beginning in September 1990, Energy Systems supervised drilling activities for eight monitoring wells, the last of which was completed in December 1990. 9 refs., 3more » figs., 2 tabs.« less

This paper is a case history comparing and evaluating the effects of fracturing the Reef Ridge Diatomite formation in the Midway-Sunset Field, Kern County, California, using {open_quotes}select-fire{close_quotes} and {open_quotes}point-source{close_quotes} perforating completions. A description of the reservoir, production history, and fracturing techniques used leading up to this study is presented. Fracturing treatment analysis and production history matching were used to evaluate the reservoir and fracturing parameters for both completion types. The work showed that single fractures were created with the point-source (PS) completions, and multiple fractures resulted from many of the select-fire (SF) completions. A good correlation was developed between productivitymore » and the product of formation permeability, net fracture height, bottomhole pressure, and propped fracture length. Results supported the continued development of 10 wells using the PS concept with a more efficient treatment design, resulting in substantial cost savings.« less

To estimate hepatitis A vaccine series initiation and completion rates, assess time to vaccination, identify missed opportunities for the hepatitis A vaccine series, and examine factors associated with hepatitis A vaccine series initiation and completion. We conducted a retrospective, observational study using three healthcare claims databases separately. The study population was comprised of children born between years 2005 and 2009 that were continuously enrolled for at least three and a half years from the date of birth. Every child was followed from date of birth for three and a half years for hepatitis A vaccination. There were 93,735 eligible children from Clinformatics Data Mart, 202,513 from MarketScan Commercial, and 207,545 from MarketScan Medicaid. The overall hepatitis A vaccine series initiation rate was 63.8-79.4% and completion rate was 45.1-66.8% across the three databases. About 62.8-90.1% of the children who never initiated hepatitis A vaccine had at least one well visit from 1 year to three and a half years old. Children were more likely to initiate and complete the hepatitis A vaccine series if they were from more recent birth cohorts, from states with a hepatitis A vaccination recommendation prior to the ACIP universal recommendation, from states with daycare/school entry requirements, were enrolled in an HMO health plan, had pediatricians as primary providers, had more doctor's office/well visits and received MMR/Varicella vaccines. In this study, approximately one in every three to five children remained unvaccinated against hepatitis A. Although the hepatitis A vaccine series initiation and completion improved from 2005 to 2009, vaccine coverage has stabilized in recent years. It is important for providers to identify every opportunity for hepatitis A vaccination and to assure that children get protection from this vaccine-preventable disease. Copyright © 2015 The Authors.

Factors that affect latent tuberculosis infection (LTBI) treatment completion in the US have not been well studied beyond public health settings. This gap was highlighted by recent health insurance-related regulatory changes that are likely to increase LTBI treatment by private sector healthcare providers. We analyzed LTBI treatment completion in the private healthcare setting to facilitate planning around this important opportunity for tuberculosis (TB) control in the US. We analyzed a national sample of commercial insurance medical and pharmacy claims data for people ages 0 to 64 years who initiated daily dose isoniazid treatment between July 2011 and March 2014 and who had complete data. All individuals resided in the US. Factors associated with treatment completion were examined using multivariable generalized ordered logit models and bivariate Kruskal-Wallis tests or Spearman correlations. We identified 1072 individuals with complete data who initiated isoniazid LTBI treatment. Treatment completion was significantly associated with less restrictive health insurance, age < 15 years, patient location, use of interferon-gamma release assays, non-poverty, HIV diagnosis, immunosuppressive drug therapy, and higher cumulative counts of clinical risk factors. Private sector healthcare claims data provide insights into LTBI treatment completion patterns and patient/provider behaviors. Such information is critical to understanding the opportunities and limitations of private healthcare in the US to support treatment completion as this sector's role in protecting against and eliminating TB grows.

Water-Quality Constituents, Dissolved-Organic-Carbon Fractions, and Disinfection By-Product Formation in Water from Community Water-Supply Wells in New Jersey, 1998-99

Hopple, Jessica A.; Barringer, Julia L.; Koleis, Janece

Water samples were collected from 20 community water-supply wells in New Jersey to assess the chemical quality of the water before and after chlorination, to characterize the types of organic carbon present, and to determine the disinfection by-product formation potential. Water from the selected wells previously had been shown to contain concentrations of dissolved organic carbon (DOC) that were greater than 0.2 mg/L. Of the selected wells, five are completed in unconfined (or semi-confined) glacial-sediment aquifers of the Piedmont and Highlands (New England) Physiographic Provinces, five are completed in unconfined bedrock aquifers of the Piedmont Physiographic Province, and ten are completed in unconsolidated sediments of the Coastal Plain Physiographic Province. Four of the ten wells in the Coastal Plain are completed in confined parts of the aquifers; the other six are in unconfined aquifers. One or more volatile organic compounds (VOCs) were detected in untreated water from all of the 16 wells in unconfined aquifers, some at concentrations greater than maximum contaminant levels. Those compounds detected included aliphatic compounds such as trichloroethylene and 1,1,1-trichloroethane, aromatic compounds such as benzene, the trihalomethane compound, chloroform, and the gasoline additive methyl tert-butyl ether (MTBE). Concentrations of sodium and chloride in water from one well in a bedrock aquifer and sulfate in water from another exceeded New Jersey secondary standards for drinking water. The source of the sulfate was geologic materials, but the sodium and chloride probably were derived from human inputs. DOC fractions were separated by passing water samples through XAD resin columns to determine hydrophobic fractions from hydrophilic fractions. Concentrations of hydrophobic acids were slightly lower than those of combined hydrophilic acids, neutral compounds, and low molecular weight compounds in most samples. Water samples from the 20 wells were adjusted to a pH of 7, dosed with sodium hypochlorite, and incubated for 168 hours (seven days) at 25 ?C to form disinfection by-products (DBPs). Concentrations of the DBPs-trihalomethanes, haloacetic acids, haloacetonitriles, and chlorate-were measured. Concentrations of these compounds, with few exceptions, were higher in water from Coastal Plain wells than from wells in glacial and bedrock aquifers. The organic-carbon fractions were dosed with sodium hypochlorite, incubated for 168 hours at 25 ?C, and analyzed for trihalomethanes, haloacetic acids, haloacetonitriles, and chlorate. Concentrations of trihalomethanes and haloacetic acids were higher in most of the hydrophobic organic-acid fractions than in the hydrophilic fractions, with the highest concentrations in samples from Coastal Plain aquifers. Traces of haloacetonitriles were measured, mostly in the hydrophilic fraction. The aromaticity of the precursor DOC, as estimated by measurements of the absorbance of ultraviolet light at 254 nanometers, apparently is a factor in the DBP formation potentials determined, as aromaticity was greater in the samples that developed high concentrations of DBPs. VOCs may have contributed to the organic carbon present in some of the samples, but much of the DOC present in water from the 20 wells appeared to be natural in origin. The sediments of the Coastal Plain aquifers, in particular, contain substantial amounts of organic matter, which contribute ammonia, organic nitrogen, and aromatic DOC compounds to the ground water. Thus, the geologic characteristics of the aquifers appear to be a major factor in the potential for ground water to form DBPs when chlorinated.

This study explored the moderating and mediating influences of self-acceptance and tolerance to others in the relationship between mindfulness and subjective well-being. In total, 301 (130 males) university students completed the Five-Facet Mindfulness Questionnaire, Index of Well-being, Self-acceptance Questionnaire, and Tolerance Scale. The results showed that the positive link between mindfulness and subjective well-being was significantly mediated by self-acceptance only. Tolerance played a moderating role. The implications of the results for relevant research and mindfulness training were discussed. © The Author(s) 2014.

The role of convexity in perceptual completion: beyond good continuation.

Liu, Z; Jacobs, D W; Basri, R

1999-01-01

Since the seminal work of the Gestalt psychologists, there has been great interest in understanding what factors determine the perceptual organization of images. While the Gestaltists demonstrated the significance of grouping cues such as similarity, proximity and good continuation, it has not been well understood whether their catalog of grouping cues is complete--in part due to the paucity of effective methodologies for examining the significance of various grouping cues. We describe a novel, objective method to study perceptual grouping of planar regions separated by an occluder. We demonstrate that the stronger the grouping between two such regions, the harder it will be to resolve their relative stereoscopic depth. We use this new method to call into question many existing theories of perceptual completion (Ullman, S. (1976). Biological Cybernetics, 25, 1-6; Shashua, A., & Ullman, S. (1988). 2nd International Conference on Computer Vision (pp. 321-327); Parent, P., & Zucker, S. (1989). IEEE Transactions on Pattern Analysis and Machine Intelligence, 11, 823-839; Kellman, P.

Neural Computation, 9, 837-858) that are based on Gestalt grouping cues by demonstrating that convexity plays a strong role in perceptual completion. In some cases convexity dominates the effects of the well known Gestalt cue of good continuation. While convexity has been known to play a role in figure/ground segmentation (Rubin, 1927; Kanizsa & Gerbino, 1976), this is the first demonstration of its importance in perceptual completion.

The RAPPER II study investigates the feasibility, safety and acceptability of using the REX self-stabilising robotic exoskeleton in people with spinal cord injury (SCI) who are obligatory wheelchair users. Feasibility is assessed by the completion of transfer into the REX device, competency in achieving autonomous control and completion of upper body exercise in an upright position in the REX device. Safety is measured by the occurrence of serious adverse events. Device acceptability is assessed with a user questionnaire. RAPPER II is a prospective, multi-centre, open label, non-randomised, non-comparative cohort study in people with SCI recruited from neurological rehabilitation centres in the United Kingdom, Australia and New Zealand. This is the planned interim report of the first 20 participants. Each completed a transfer into the REX, were trained to achieve machine control and completed Timed Up and Go (TUG) tests as well as upper body exercises in standing in a single first time session. The time to achieve each task as well as the amount of assistance required was recorded. After finishing the trial tasks a User Experience questionnaire, exploring device acceptability, was completed. All participants could transfer into the REX. The mean transfer time was 439 s. Nineteen completed the exercise regime. Eighteen could achieve autonomous control of the REX, 17 of whom needed either no assistance or the help of just one therapist. Eighteen participants completed at least one TUG test in a mean time of 313 s, 15 with the assistance of just one therapist. The questionnaire demonstrated high levels of acceptability amongst users. There were no Serious Adverse Events. This first interim analysis of RAPPER II shows that it is feasible and safe for people with SCI to use the REX powered assisted walking device to ambulate and exercise in. Participants with tetraplegia and paraplegia could walk and perform a functional exercise program when standing needing only modest levels of assistance in most cases. User acceptability was high.

Objectives To examine factors that enhance under-screened and never-screened women’s completion of the self-collection alternative pathway of the Renewed National Cervical Screening Program (ncsp) in Victoria, Australia. Background With the Australian ncsp changing, starting on 1 December 2017, the Medical Services Advisory Committee (msac) recommended implementing human papillomavirus (hpv) testing using a self-collected sample for under-screened and never-screened populations. In response, a multi-agency group implemented an hpv self-collection pilot project to trial self-collection screening pathways for eligible women. Methods Quantitative data were collected on participation rates and compliance rates with follow-up procedures across three primary health care settings. Forty women who self-collected were interviewed in a semi-structured format, and seven agency staff completed in-depth interviews. Qualitative data were used to identify and understand clinical and personal enablers that assisted women to complete self-collection cervical screening pathways successfully. Results Eighty-five per cent (10 women) of participants who tested positive for hpv successfully received their results and completed follow-up procedures as required. Two remaining participants also received hpv-positive results. However, agencies were unable to engage them in follow-up services and procedures. The overall participation rate in screening (self-collection or Pap test) was 85.7% (84 women), with 79 women self-collecting. Qualitative data indicated that clear explanations on self-collection, development of trusting, empathetic relationships with health professionals, and recognition of participants’ past experiences were critical to the successful completion of the self-collection pathway. When asked about possible inhibitors to screening and to following up on results and appointments, women cited poor physical and mental health, as well as financial and other structural barriers. Conclusion A well-implemented process, led by trusted, knowledgeable, and engaged health care professionals who can provide appropriate support and information, can assist under-screened and never-screened women to complete the hpv self-collection pathway successfully.
