    Our objective in the characterization of sediments from Seaplane Lagoon at the Alameda Naval Air Station (NAS) was to determine the geochemical interactions that control the partitioning of cadmium, chromium, cobalt, copper, lead, mercury, nickel, and zinc between the sediments and the porewaters. Our approach was to collect several cores at the east outfall location of the Seaplane Lagoon. We determined the porewater chemistry by (1) making in situ micro-electrode measurements, (2) extracting porewaters, and (3) modeling geochemical reactions. We determined the sediment chemistry by measuring (1) elemental abundance, (2) mineralogy, and (3) trace-element speciation. This information should help the US Navy determine the long-term hazard of the sediments if they are left in place and the short-term hazard if they are dredged. We did not fully examine the geochemistry of sediments from the West Beach Landfill Wetlands site, because these sediments were distinct from the Seaplane Lagoon sediments. Our initial motivation for studying the Landfill Wetlands site was to determine the trace-element geochemistry in Seaplane Lagoon sediments that had been dredged and then disposed in the Landfill Wetlands. Unfortunately, the location of these dredged sediments is unknown. The cores we sampled were not from the Seaplane Lagoon.

  3. Speciation and Fate of Trace Metals in Estuarine Sediments Under Reduced and Oxidized Conditions, Seaplane Lagoon, Alameda Naval Air Station

    We have identified important chemical reactions that control the fate of metal-contaminated estuarine sediments if they are left undisturbed (in situ) or if they are dredged. We combined information on the molecular bonding of metals in solids from X-ray absorption spectroscopy (XAS) with thermodynamic and kinetic driving forces obtained from dissolved metal concentrations to deduce the dominant reactions under reduced and oxidized conditions. We evaluated the in situ geochemistry of metals (cadmium, chromium, iron, lead, manganese and zinc) as a function of sediment depth (to 100 cm) from a 60-year record of contamination at the Alameda Naval Air Station, California. Results from XAS and thermodynamic modeling of porewaters show that cadmium and most of the zinc form stable sulfide phases, and that lead and chromium are associated with stable carbonate, phosphate, phyllosilicate, or oxide minerals. Therefore, there is minimal risk associated with the release of these trace metals from the deeper sediments contaminated prior to the Clean Water Act (1975) as long as reducing conditions are maintained. Increased concentrations of dissolved metals with depth were indicative of the formation of metal HS- complexes. The sediments also contain zinc, chromium, and manganese associated with detrital iron-rich phyllosilicates and/or oxides. These phases are recalcitrant at near-neutral pH and do not undergo reductive dissolution within the 60-year depositional history of sediments at this site. The fate of these metals during dredging was evaluated by comparing in situ geochemistry with that of sediments oxidized by seawater in laboratory experiments. Cadmium and zinc pose the greatest hazard from dredging because their sulfides were highly reactive in seawater. However, their dissolved concentrations under oxic conditions were limited eventually by sorption to or co-precipitation with an iron (oxy)hydroxide. About 50% of the reacted CdS and 80% of the reacted ZnS were

  8. Indoor air quality and infiltration in multifamily naval housing

    International Nuclear Information System (INIS)

    Measurements of indoor air quality and air infiltration were taken in three units of a multifamily housing complex at the Naval Submarine base in Bangor, Washington, over 5 consecutive days during the heating season of 1983. Three dwelling units of identical size constructed in 1978 were monitored, each in a separate two-story four-unit complex. One unit was a downstairs unit and the other two units were upstairs units. Two of the units were occupied by smokers (one downstairs and one upstairs). None of the units had combustion appliances. Pollutants monitored indoors included radon, formaldehyde, carbon monoxide, particulate matter, and nitrogen dioxide. Indoor and outdoor temperature and windspeed were also recorded. Outdoor formaldehyde and nitrogen dioxide were also measured. Air exchange was measured about three times during each 24-h period, using a perfluorocarbon tracer with automatic tracer sampling. The daily average air exchange rate ranged from 0.22 to 0.91 air changes per hour (ACH). Pollutant concentrations were generally low except for particulate matter in the units with smokers, which were two to four times higher than in the unit with nonsmokers. Levels of carbon monoxide were also slightly elevated in one of the units with a smoker compared to the unit with nonsmokers. 5 references, 4 figures, 4 tables

    1995-01-01

    The geologic formations that crop out near Naval Air Station Chase Field and Naval Auxiliary Landing Field Goliad military bases consist of fluvial to fluvial-deltaic sediments of Tertiary and Quaternary age. These formations include the Fleming and Goliad Formations of Miocene age, Lissie Formation of Pleistocene age, fluvial terrace deposits of Pleistocene to Holocene age, and alluvium of Holocene age. The lithology of these formations consists of sand, sandstone, silt, and clay, with lesser amounts of gravel and caliche in the outcrops. The freshwater aquifers underlying the study area are the unconfined Evangeline (watertable) aquifer, comprising the upper sandy parts of the Fleming Formation and Goliad Formation, and confined Fleming aquifers, comprising the thick sandstone beds of the Fleming Formation. Both military bases withdraw potable water from one of the confined aquifers. At Naval Air Station Chase Field, the transmissivity and storativity of the confined aquifer where the base withdraws its public water supply are 1,060 feet squared per day and 1.2xlO4, respectively, as computed from the results of a 74-hour constant-discharge aquifer test. Selected water-quality field measurements of specific conductance, pH, and temperature indicate that each of the three aquifers at Naval Air Station Chase Field are somewhat insulated from one another by the intervening confining units. Large vertical hydraulic-head gradients are present between the unconfined Evangeline aquifer and confined Fleming aquifers at Naval Air Station Chase Field and Naval Auxiliary Landing Field Goliad. These gradients, together with the results of the aquifer test at Naval Air Station Chase Field and assumed characteristics of the confining units, indicate that downward flow of ground water probably occurs from the water-table aquifer to the underlying aquifers. The rate of downward flow between the two confined Fleming aquifers (from A-sand to B-sand) can be approximated using an

    1993-05-01

    In a field evaluation conducted for the US Department of Energy (DOE) Office of Federal Energy Management Program (FEMP), the Pacific Northwest Laboratory (PNL) examined the performance of a new US energy-related technology under the FEMP Test Bed Demonstration Program. The technology was a 15-ton natural gas engine driven roof top air conditioning unit. Two such units were installed on a naval retail building to provide space conditioning to the building. Under the Test Bed Demonstration Program, private and public sector interests are focused to support the installation and evaluation of new US technologies in the federal sector. Participating in this effort under a Cooperative Research and Development Agreement (CRADA) with DOE were the American Gas Cooling Center, Philadelphia Electric Company, Thermo King Corporation, and the US Naval Air Station at Willow Grove, Pennsylvania. Equipment operating and service data as well as building interior and exterior conditions were secured for the 1992 cooling season. Based on a computer assessment of the building using standard weather data, a comparison was made with the energy and operating costs associated with the previous space conditioning system. Based on performance during the 1992 cooling season and adjusted to a normal weather year, the technology will save the site $6,000/yr in purchased energy costs. An additional $9,000 in savings due to electricity demand ratchet charge reductions will also be realized. Detailed information on the technology, the installation, and the results of the technology test are provided to illustrate the advantages to the federal sector of using this technology. A history of the CRADA development process is also reported.

    2010-12-01

    The number of bird strikes on aircraft has increased sharply over recent years and airport bird hazard management has gained increasing attention in wildlife management and control. Evaluation of bird activity near airport is very critical to analyze the hazard of bird strikes. Traditional methods for bird activity analysis using visual counting provide a direct approach to bird hazard assessment. However this approach is limited to daylight and good visual conditions. Radar has been proven to be a useful and effective tool for bird detection and movement analysis. Radar eliminates observation bias and supports consistent data collection for bird activity analysis and hazard management. In this study bird activity data from the Naval Air Station Whidbey Island was collected by Accipiter Avian Radar System. Radar data was pre-processed by filtering out non-bird noises, including traffic vehicle, aircraft, insects, wind, rainfall, ocean waves and so on. Filtered data is then statistically analyzed using MATLAB programs. The results indicated bird movement dynamics in target areas near the airport, which includes (1) the daily activity varied at dawn and dusk; (2) bird activity varied by target area due to the habitat difference; and (3) both temporal and spatial movement patterns varied by bird species. This bird activity analysis supports bird hazard evaluation and related analysis and modeling to provide very useful information in airport bird hazard management planning.

    Several U.S. Department of Defense base studies have been conducted to identify potential U.S. Department of Defense transportation systems that are strong candidates for introduction or expansion of plug-in electric vehicles (PEVs). This study is focused on the Naval Air Station Whidbey Island (NASWI) located in Washington State. Task 1 consisted of a survey of the non-tactical fleet of vehicles at NASWI to begin the review of vehicle mission assignments and types of vehicles in service. In Task 2, daily operational characteristics of vehicles were identified to select vehicles for further monitoring and attachment of data loggers. Task 3 recorded vehicle movements in order to characterize the vehicles’ missions. The results of the data analysis and observations were provided. Individual observations of the selected vehicles provided the basis for recommendations related to PEV adoption, i.e., whether a battery electric vehicle (BEV) or plug-in hybrid electric vehicle (PHEV) (collectively PEVs) can fulfill the mission requirements. It also provided the basis for recommendations related to placement of PEV charging infrastructure. This report focuses on an implementation plan for the near-term adoption of PEVs into the NASWI fleet.

  5. Soils washing for removal of heavy oil: Naval Air Engineering Center, Lakehurst, NJ

    International Nuclear Information System (INIS)

    With the recognition that large tracts of land are currently unusable as a result of either accidental spills or past industrial practices (such as oil field development), the USEPA Office of Research and Development evaluated soil washing as an alternative remedial technology for heavy oil contaminated soil at a site located on the Naval Air Engineering Center (NAEC), Lakehurst, New Jersey. The researchers used a self-contained, 100-pound-per-hour soil washer. Electrical, pneumatic, and fluid-pumping capabilities were provided by the trailer-mounted system at a remote No. 6 type oil spill site at the Navy base. Chloroform extracts of the contaminated sandy soil recovered a 0.91 gram/milliliter, 950 centistoke viscosity, dark brown, non-PCB oil. By using a surfactant/solvent solution at ambient temperatures, contaminant levels on the soil were reduced from 3.8% (38,000 milligram/kilogram-RCRA hazardous waste designation) to as low as 0.035% (350 milligram/kilogram) oil concentration. Supplemental laboratory evaluations extending the pilot field evaluations showed at elevated temperatures (120F) that residual oil contamination was less than 0.01% (100 milligram/kilogram). This final oil concentration in the treated soil would be defined as clean under the New Jersey Environmental Cleanup and Responsibilities Act (ECRA). A continuous belt press filter was used to recover the oil in a 47% solids cake that could be used as a secondary fuel feed to a waste boiler. The wash water solution was treated and recycled permitting economical operations

    Full Text Available At the end of the XVIII century, in Caracas, a promenade related to Paseo del Prado, Madrid, was projected by the Governor Manuel González y Torres de Navarra. Small evidence of its construction has led some historians to assert that la alameda was never built. However, after examining historic documents, old maps and planes or the city, this article advances the alameda was indeed built to survive the 1812's earthquake, and the Independence war. In 1858, another promenade, el paseo de Caracas was projected on the same site were la alameda was once located.

    A finales del siglo XVIII, y promovida por el gobernador Manuel González y Torres de Navarra, se proyectó en la provincia de Caracas una alameda que estaría emparentada con el Paseo del Prado de Madrid. La escasa información sobre este proyecto ha contribuido a que muchos historiadores duden de su existencia. Sin embargo, la revisión de fuentes documentales y antiguos planos de la ciudad permiten deducir que la alameda no sólo se construyó, sino que sobrevivió a los embates del terremoto de 1812 y la Guerra de Independencia, sirviendo de base para la propuesta del Paseo de Caracas que, en 1858, se propuso en ese mismo lugar.

    1995-01-01

    Chorio-allantoic membranes (CAMs) were collected and analyzed for chlorinated hydrocarbons as part of a wildlife toxicology demonstration project at Naval Air Station (NAS) Whidbey Island, Washington, USA. Concentrations of DDT, DDE, DDD, Aroclor 1254, and Aroclor 1260 were found at concentrations below 0.4 ppm for 13 of 14 samples. The low correlations among DDT and its metabolites in CAMs suggest herons are not being exposed to a consistent source of these compounds. Comparison of chlorinated hydrocarbon data for CAMs from three Puget Sound heron colonies, NAS Whidbey, Samish Island and Dumas Bay, indicates contaminant burdens in herons from NAS Whidbey and Samish Island are significantly lower than burdens in herons from Dumas Bay.

    This technical memorandum develops process options which are appropriate for environmental restoration activities at Naval Air Station Fallon (NAS Fallon), Nevada. Introduction of contaminants to the environment has resulted from deliberate disposal activities (both through dumping and landfilling) and accidental spills and leaks associated with normal activities at NAS Fallon over its lifetime of operation. Environmental sampling results indicate that the vast majority of contaminants of concern are petroleum hydrocarbon related. These contaminants include JP-4, JP-5, leaded and unleaded gasoline, waste oils and lubricants, hydraulic fluids, and numerous solvents and cleaners. The principal exposure pathways of concern associated with NAS Fallon contaminants appear to be the surface flows and shallow drainage systems to which the base contributes. Available data indicate NAS Fallon IR Program sites are not contributing excessive contamination to surface flows emanating from the base. Contaminants appear to be contained in a relatively immobile state in the shallow subsurface with little or no contaminant migration off site.

    Archival material has revealed milestones and new details in the history of the Norwegian Naval Observatories. We have identified several of the instrument types used at different epochs. Observational results have been extracted from handwritten sources and an extensive literature search. These allow determination of an approximate location of the first naval observatory building (1842) at Fredriksvern. No physical remains exist today. A second observatory was established in 1854 at the new main naval base at Horten. Its location is evident on military maps and photographs. We describe its development until the Naval Observatory buildings, including archives and instruments, were completely demolished during an allied air bomb raid on 23 February 1945. The first director, C.T.H. Geelmuyden, maintained scientific standards at the the Observatory between 1842 and 1870, and collaborated with university astronomers to investigate, develop, and employ time-transfer by telegraphy. Their purpose was accurate longitude determination between observatories in Norway and abroad. The Naval Observatory issued telegraphic time signals twice weekly to a national network of sites, and as such served as the first national time-service in Norway. Later the Naval Observatory focused on the particular needs of the Navy and developed into an internal navigational service.

  14. Performance and Economics of a Wind-Diesel Hybrid Energy System: Naval Air Landing Field, San Clemente Island, California; TOPICAL

    International Nuclear Information System (INIS)

    This report provides an overview of the wind resource, economics and operation of the recently installed wind turbines in conjunction with diesel power for the Naval Air Landing Field (NALF), San Clemente Island (SCI), California Project. The primary goal of the SCI wind power system is to operate with the existing diesel power plant and provide equivalent or better power quality and system reliability than the existing diesel system. The wind system is also intended to reduce, as far as possible, the use of diesel fuel and the inherent generation of nitrogen-oxide emissions and other pollutants. The first two NM 225/30 225kW wind turbines were installed and started shake-down operations on February 5, 1998. This report describes the initial operational data gathered from February 1998 through January 1999, as well as the SCI wind resource and initial cost of energy provided by the wind turbines on SCI. In support of this objective, several years of data on the wind resources of San Clemente Island were collected and compared to historical data. The wind resource data were used as input to economic and feasibility studies for a wind-diesel hybrid installation for SCI

    2006-12-01

    A long-term monitoring program was initiated in 1995 at 6 sites at NAS Brunswick, including 3 National Priorities List (Superfund) sites. Primary contaminants of concern include chlorinated volatile organic compounds, including tetrachloroethane, trichloroethene, and vinyl chloride, in addition to metals. More than 80 submersible pumping systems were installed to facilitate sample collection utilizing the low-flow sampling technique. Long-term monitoring of the groundwater is conducted to assess the effectiveness of remedial measures, and monitor changes in contaminant concentrations in the Eastern Plume Operable Unit. Long-term monitoring program activities include quarterly groundwater sampling and analysis at more than 90 wells across 6 sites; surface water, sediment, seep, and leachate sampling and analysis at 3 sites; landfill gas monitoring; well maintenance; engineering inspections of landfill covers and other sites or evidence of stressed vegetation; water level gauging; and treatment plant sampling and analysis. Significant cost savings were achieved by optimizing the sampling network and reducing sampling frequency from quarterly to semi- annual or annual sampling. As part of an ongoing optimization effort, a geostatistical assessment of the Eastern Plume was conducted at the Naval Air Station, Brunswick, Maine. The geostatistical assessment used 40 monitoring points and analytical data collected over 3 years. For this geostatistical assessment, EA developed and utilized a database of analytical results generated during 3 years of long-term monitoring which was linked to a Geographic Information System to enhance data visualization capacity. The Geographic Information System included themes for groundwater volatile organic compound concentration, groundwater flow directions, shallow and deep wells, and immediate access to point-specific analytical results. This statistical analysis has been used by the site decision-maker and its conclusions supported a

    2002-01-01

    Ground-water samples were collected in April 1999 at Naval Air Station Whidbey Island, Washington, with passive diffusion samplers and a submersible pump to compare concentrations of volatile organic compounds (VOCs) in water samples collected using the two sampling methods. Single diffusion samplers were installed in wells with 10-foot screened intervals, and multiple diffusion samplers were installed in wells with 20- to 40-foot screened intervals. The diffusion samplers were recovered after 20 days and the wells were then sampled using a submersible pump. VOC concentrations in the 10-foot screened wells in water samples collected with diffusion samplers closely matched concentrations in samples collected with the submersible pump. Analysis of VOC concentrations in samples collected from the 20- to 40-foot screened wells with multiple diffusion samplers indicated vertical concentration variation within the screened interval, whereas the analysis of VOC concentrations in samples collected with the submersible pump indicated mixing during pumping. The results obtained using the two sampling methods indicate that the samples collected with the diffusion samplers were comparable with and can be considerably less expensive than samples collected using a submersible pump.

    Lacombe, Pierre J.

    2011-01-01

    Pump and Treat (P&T) remediation is the primary technique used to contain and remove trichloroethylene (TCE) and its degradation products cis 1-2,dichloroethylene (cDCE) and vinyl chloride (VC) from groundwater at the Naval Air Warfare Center (NAWC), West Trenton, NJ. Three methods were used to determine the masses of TCE, cDCE, and VC removed from groundwater by the P&T system since it became fully operational in 1996. Method 1, is based on the flow volume and concentrations of TCE, cDCE, and VC in groundwater that entered the P&T building as influent. Method 2 is based on withdrawal volume from each active recovery well and the concentrations of TCE, cDCE, and VC in the water samples from each well. Method 3 compares the maximum monthly amount of TCE, cDCE, and VC from Method 1 and Method 2. The greater of the two values is selected to represent the masses of TCE, cDCE and VC removed from groundwater each month. Previously published P&T monthly reports used Method 1 to determine the mass of TCE, cDCE, and VC removed. The reports state that 8,666 pounds (lbs) of TCE, 13,689 lbs of cDCE, and 2,455 lbs of VC were removed by the P&T system during 1996-2010. By using Method 2, the mass removed was determined to be 8,985 lbs of TCE, 17,801 lbs of cDCE, and 3,056 lbs of VC removed, and Method 3, resulted in 10,602 lbs of TCE, 21,029 lbs of cDCE, and 3,496 lbs of VC removed. To determine the mass of original TCE removed from groundwater, the individual masses of TCE, cDCE, and VC (determined using Methods 1, 2, and 3) were converted to numbers of moles, summed, and converted to pounds of original TCE. By using the molar conversion the mass of original TCE removed from groundwater by Methods 1, 2, and 3 was 32,381 lbs, 39,535 lbs, and 46,452 lbs, respectively, during 1996-2010. P&T monthly reports state that 24,805 lbs of summed TCE, cDCE, and VC were removed from groundwater. The simple summing method underestimates the mass of original TCE removed by the P&T system.

    1996-10-01

    The performance was evaluated of a new US cooling technology that has been installed for the first time at a federal facility. The technology is a 15-ton natural gas-engine-driven rooftop air conditioning unit made by Thermo King. Two units were installed to serve the Navy Exchange at Willow Grove. The savings potential at Willow Grove is described and that in the federal sector estimated. Conditions for implementation are discussed. In summary, the new technology is generally cost-effective at sites where marginal electricity cost (per MBtu at the meter) is more than 4 times the marginal gas cost (per MBtu at the meter) and annual full-load-equivalent cooling hours exceed 2,000.

  5. Alameda Dam, Saskatchewan: Viability of a halt in construction

    International Nuclear Information System (INIS)

    A report is presented on the safety of halting construction of the 40 m high Alameda Dam in Saskatchewan. Pursuant to a series of legal and administrative proceedings, Environment Canada has been authorized to order a halt in construction of the dam. The safety implications of such an action are reviewed, particularly to determine the embankment crest elevation at which construction could safely be halted for a period of up to three months. A description is presented of principal features of the dam, site condition as of July 1991, flood hydrology and routing through the project, considerations for determining the safe height of the dam, downstream effects, and desirable conditions for the 1992 flood season. It is concluded that any halt in construction of the dam would have serious implications with respect to downstream impacts as well as integrity of the dam during the 1992 flood season. Risk of overtopping the embankment, halted at elevation 545 m, during a spring flood would be of the order of 1:4, with economic consequences amounting to millions of dollars. At a level of 557 m, risk of overtopping is reduced to the order of 1:50 to 1:100, however downstream consequences of a breach increase substantially. 6 refs

    At the former Naval Air Warfare Center (NAWC) in West Trenton NJ, the U.S. Geological Survey, in cooperation with the U.S. Navy and under support from the Strategic Environmental Research and Development Program (SERDP), is investigating the fate, transport, and remediation of trichloroethylene (TCE) and its daughter products in dipping, fractured mudstones underlying the site. TCE concentrations in ground water are as high as ~100 mg/L. Objectives of multidisciplinary research at the NAWC include (1) understanding the physical, chemical, and microbiological processes and properties affecting the fate, transport, and removal of chlorinated solvents in fractured rocks, (2) assessing the efficiency of different remediation methods (pump and treat, natural and enhanced biodegradation), and (3) transferring the results to help remediate other contaminated fractured rock aquifers. There are numerous scientific and technical challenges to meeting these goals, including the extreme spatial variability of flow and transport properties at the NAWC and the complex distribution of contaminants, geochemical constituents, and microorganisms in fractures and the rock matrix. In addition, there are management challenges that are equally important to address in order to achieve a successful research program. These include balancing the requirements of the many parties involved at the site, including researchers, the site owner, and regulatory agencies; and ensuring that limited research funds are directed towards work that addresses the most important scientific questions as well as stakeholder concerns. Strategies for the scientific challenges at NAWC include developing a carefully planned program to characterize spatial variability in rock properties and groundwater constituents so that the data obtained are applicable to solving research questions focused on remediation. Strategies for the management challenges include fostering open lines of communication among all parties and

    2007-01-01

    Borehole geophysical logging, heatpulse-flowmeter measurements, borehole television surveys, and aquifer-isolation tests were conducted in 2005 at the Willow Grove Naval Air Station/Joint Reserve Base (NAS/JRB) in Horsham Township, Montgomery County, Pa. This study was done by the U.S. Geological Survey (USGS) in cooperation with the U.S. Navy in support of hydrogeological investigations to address ground-water contamination. Data collected for this study are valuable for understanding ground-water flow in the Stockton Formation at the local and regional scale. The Willow Grove NAS/JRB is underlain by the Stockton Formation, which consists of sedimentary rocks of Triassic age. The rocks of the Stockton Formation form a complex, heterogeneous aquifer with partially connected zones of high permeability. Borehole geophysical logs, heatpulse-flowmeter measurements, and borehole television surveys made in seven boreholes ranging from 70 to 350 ft deep were used to identify potential water-producing fractures and fracture zones and to select intervals for aquifer-isolation tests. An upward vertical hydraulic gradient was measured in one borehole, a downward vertical hydraulic gradient was measured in four boreholes, both an upward and a downward vertical hydraulic gradient were measured in one borehole, and no flow was measurable in one borehole. The aquifer-isolation tests isolated 30 discrete fractures in the seven boreholes for collection of depth-discrete hydraulic and water-quality data. Of the 30 fractures identified as potentially water producing, 26 fractures (87 percent) produced more than 1 gallon per minute of water. The specific capacity of the isolated intervals producing more than 1 gallon per minute ranged from 0.02 to 5.2 gallons per minute per foot. There was no relation between specific capacity and depth of the fracture. Samples for analysis for volatile organic compounds were collected from each isolated zone. Tetrachloroethylene (PCE) was the most

    Dealing with military and asymmetric threats represents a key issue for any military vessel in various environment. In order to support ship's self protection, Thales has designed a new generation of naval InfraRed Search and Track (IRST) called ARTEMIS. It has been selected to equip Future European Multi Roles Frigates (FREMM). ARTEMIS is a fully new passive staring IRST system capable of automatically detecting and tracking both air and surface targets simultaneously. It is able to detect and track maneuvering and stealthy new threats as well as surface asymmetric threats. The paper describes the novelties of the ARTEMIS staring architecture and some of its technologies. It describes also the advantages offered by this new concept of electro-optical surveillance with full static sensor heads compared to existing and future solutions, and its capabilities to comply with future integrated masts standards. The paper concludes by a presentation of the product for the French Navy.

    Ground water pumped from supply wells 1 and 2 on the Willow Grove Naval Air Station/Joint Reserve Base (NAS/JRB) provides water for use at the base, including potable water for drinking. The supply wells have been contaminated by volatile organic compounds (VOC?s), particularly trichloroethylene (TCE) and tetrachloroethylene (PCE), and the water is treated to remove the VOC?s. The Willow Grove NAS/JRB and surrounding area are underlain by sedimentary rocks of the Triassic-age Stockton Formation, which form a complex, heterogeneous aquifer. The ground-water-flow system for the supply wells was characterized by use of borehole geophysical logs and heatpulse-flowmeter measurements. The heatpulse-flowmeter measurements showed upward and downward borehole flow under nonpumping conditions in both wells. The hydraulic and chemical properties of discrete water-bearing fractures in the supply wells were characterized by isolating each water-bearing fracture with straddle packers. Eight fractures in supply well 1 and five fractures in supply well 2 were selected for testing on the basis of the borehole geophysical logs and borehole television surveys. Water samples were collected from each isolated fracture and analyzed for VOC?s and inorganic constituents. Fractures at 50?59, 79?80, 196, 124?152, 182, 241, 256, and 350?354 ft btoc (feet below top of casing) were isolated in supply well 1. Specific capacities ranged from 0.26 to 5.7 (gal/min)/ft (gallons per minute per foot) of drawdown. The highest specific capacity was for the fracture isolated at 179.8?188 ft btoc. Specific capacity and depth of fracture were not related in either supply well. The highest concentrations of PCE were in water samples collected from fractures isolated at 236.8?245 and 249.8?258 ft btoc, which are hydraulically connected. The concentration of PCE generally increased with depth to a maximum of 39 mg/L (micrograms per liter) at a depth of 249.8? 258 ft btoc and then decreased to 21 mg/L at a

    On June 12,2003, the Alameda County Public Health Department and Sandia National Laboratories/CA jointly conducted an exercise that used a Weapons of Mass Destruction-Decision Analysis Center (WMD-DAC) bioterrorism attack simulation to test the effectiveness of the county's emergency response plan. The exercise was driven by an assumed release (in the vicinity of the Berkeley Marina), and subsequent spread, of a small quantity of aerosolized, weapons-grade anthrax spores. The simulation used several key WMD-DAC capabilities, namely: (1) integration with an atmospheric dispersion model to calculate expected dose levels in the affected areas, (2) a individual-tracking capability for both infected and non-infected persons as they made decisions, sought treatment, and received prophylaxis drugs, and (3) a user interface that allows exercise participants to affect the scenario evolution and outcome. The analysis of the county's response plan included documenting and reviewing the decisions made by participants during the exercise. Twenty-six local and regional officials representing the health care system, emergency medical services and law enforcement were involved in responding to the simulated attack. The results of this joint effort include lessons learned both by the Alameda County officials regarding implementation of their bioterrorism response plan and by the Sandia representatives about conducting exercises of this type. These observations are reviewed in this report, and they form a basis for providing a better understanding of group/individual decision processes and for identifying effective communication options among decision makers.

    As soon as 1942 the application of nuclear energy to the propulsion of submarines was yet quoted as very promising. For 40 years this type of propulsion has been applied to submarines, aircraft carriers and ice-breakers. A review of the different kinds of ships is made and a perspective for a near future is drawn. The historical aspect of the successive French programs is presented and the development of the concept due to the progress of technology and experience is highlighted. The Charles de Gaulle aircraft carrier will benefit fully from its nuclear propulsion system. This system allows: -autonomy with the supplying of almost no limited amount of electricity, -compactness, the absence of chimneys facilitates the use of the flight-deck, -a reduction of the mass, a classical propulsion system requires 8000 tons of fuel, -a great maneuverability and a high level of reliability. Naval propulsion presents the engineers with specific problems. The exiguity of ships implies the entanglement of different systems, for instance, the water reserve is used as a radiation shielding. The ship maneuverability requires a high flexibility of the power supply: from 10% to 100% of the nominal power delivered in less than one minute. The particular auto-stability of the pressurized water reactor type which can sustain sharp power transients by a rise of only 10 degrees of the moderator temperature has been one of the main assets of this type of reactor to the naval propulsion.

    Steinberg, Marc

    2006-05-01

    This paper provides an overview of the development and demonstration of intelligent autonomy technologies for control of heterogeneous unmanned naval air and sea vehicles and describes some of the current limitations of such technologies. The focus is on modular technologies that support highly automated retasking and fully autonomous dynamic replanning for up to ten heterogeneous unmanned systems based on high-level mission objectives, priorities, constraints, and Rules-of-Engagement. A key aspect of the demonstrations is incorporating frequent naval operator evaluations in order to gain better understanding of the integrated man/machine system and its tactical utility. These evaluations help ensure that the automation can provide information to the user in a meaningful way and that the user has a sufficient level of control and situation awareness to task the system as needed to complete complex mission tasks. Another important aspect of the program is examination of the interactions of higher-level autonomy algorithms with other relevant components that would be needed within the decision-making and control loops. Examples of these are vision and other sensor processing algorithms, sensor fusion, obstacle avoidance, and other lower level vehicle autonomous navigation, guidance, and control functions. Initial experiments have been completed using medium and high-fidelity vehicle simulations in a virtual warfare environment and inexpensive surrogate vehicles in flight and in-water demonstrations. Simulation experiments included integration of multi-vehicle task allocation, dynamic replanning under constraints, lower level autonomous vehicle control, automatic assessment of the impact of contingencies on plans, management of situation awareness data, operator alert management, and a mixed-initiative operator interface. In-water demonstrations of a maritime situation awareness capability were completed in both a river and a harbor environment using unmanned surface

  3. Naval Petroleum and Oil Shale Reserves

    International Nuclear Information System (INIS)

    During fiscal year 1992, the reserves generated $473 million in revenues, a $181 million decrease from the fiscal year 1991 revenues, primarily due to significant decreases in oil and natural gas prices. Total costs were $200 million, resulting in net cash flow of $273 million, compared with $454 million in fiscal year 1991. From 1976 through fiscal year 1992, the Naval Petroleum and Oil Shale Reserves generated more than $15 billion in revenues and a net operating income after costs of $12.5 billion. In fiscal year 1992, production at the Naval Petroleum Reserves at maximum efficient rates yielded 26 million barrels of crude oil, 119 billion cubic feet of natural gas, and 164 million gallons of natural gas liquids. From April to November 1992, senior managers from the Naval Petroleum and Oil Shale Reserves held a series of three workshops in Boulder, Colorado, in order to build a comprehensive Strategic Plan as required by Secretary of Energy Notice 25A-91. Other highlights are presented for the following: Naval Petroleum Reserve No. 1--production achievements, crude oil shipments to the strategic petroleum reserve, horizontal drilling, shallow oil zone gas injection project, environment and safety, and vanpool program; Naval Petroleum Reserve No. 2--new management and operating contractor and exploration drilling; Naval Petroleum Reserve No. 3--steamflood; Naval Oil Shale Reserves--protection program; and Tiger Team environmental assessment of the Naval Petroleum and Oil Shale Reserves in Colorado, Utah, and Wyoming

  4. Naval Firepower and its Role in Land Battles

    Full Text Available Inside the crowded geo-strategic box that is Israel’s domain, the western sector is the only open border and is thus both the Achilles’ heel of Israel enemies and a great opportunity for the IDF. At the same time, technological improvements on the enemy’s side and its growing arsenal of a wide range of rockets and missiles are a severe threat to Israel in every land battle. In the sea domain the navy enjoys many advantages: it is a constant presence in the arena, it is difficult to track, its activity is possible in almost every weather condition, the sea medium affords ways to avoid detection, it operates beyond range of enemy’s weapons (which is not the case for most air force and ground troops bases, and it allows a large scope of armaments on a single naval platform. The IDF must build its naval force to take advantage of this situation. The IDF has yet to realize the full potential of incorporating naval force as an integral part of land battles using accurate long range missiles fired in salvoes from the sea.Over the last decade, several dramatic changes in the nature of war have taken place in the Middle East, requiring thought, analysis, and lesson-learning – i.e., a different implementation of operational action.

  5. Variations in population exposure and evacuation potential to multiple tsunami evacuation phases on Alameda and Bay Farm Islands, California

    Science.gov (United States)

    Peters, J.

    2015-12-01

    Planning for a tsunami evacuation is challenging for California communities due to the variety of earthquake sources that could generate a tsunami. A maximum tsunami inundation zone is currently the basis for all tsunami evacuations in California, although an Evacuation Playbook consisting of specific event-based evacuation phases relating to flooding severity is in development. We chose to investigate the Evacuation Playbook approach for the island community of Alameda, CA since past reports estimated a significant difference in numbers of residents in the maximum inundation zone when compared to an event-based inundation zone. In order to recognize variations in the types of residents and businesses within each phase, a population exposure analysis was conducted for each of the four Alameda evacuation phases. A pedestrian evacuation analysis using an anisotropic, path distance model was also conducted to understand the time it would take for populations to reach high ground by foot. Initial results suggest that the two islands of the City of Alameda have different situations when it comes to the four tsunami evacuation phases. Pedestrian evacuation results suggest that Bay Farm Island would have more success evacuating by vehicle due to limited nearby high ground for pedestrians to reach safety. Therefore, agent-based traffic simulation software was used to model vehicle evacuation off Bay Farm Island. Initial results show that Alameda Island could face challenges evacuating numerous boat docks and a large beach for phases 1 and 2, whereas Bay Farm Island is unaffected at these phases but might be challenged with evacuating by vehicle for phases 3 and maximum due to congestion on limited egress routes. A better understanding of the population exposure within each tsunami Evacuation Playbook phase and the time it would take to evacuate out of each phase by foot or vehicle will help emergency managers implement the evacuation phases during an actual tsunami event.

  6. Naval arms control: Tons of options?

    International Nuclear Information System (INIS)

    Arms reductions have reached the US Navy, the most arms control averse of the US services, with budget-driven cuts in numbers of ships and personnel, and President Bush's unilateral withdrawal of tactical nuclear weapons. Soviet President Mikhail Gorbachev's rejoinder not only replicated the Bush initiative for naval weapons, but also called for the destruction of all those weapons, many of which would simply be placed in secure storage ashore under Bush's approach. Can formal, negotiated naval arms control agreements be far behind? Post-war history suggests that such naval arms agreements will remain out of reach. But post-war history has been confounded repeatedly by the events of the past three years. There are, in fact, negotiated naval limits that would enhance the predictability of US-Soviet military relations, and smooth the path of the naval retrenchment already underway on both sides. The Bush-Gorbachev reciprocal withdrawals of naval tactical nuclear arms deal with the most urgent and dangerous issue for naval arms control, improve the US Navy's survivability by drastically reducing the nuclear threat, and improve its flexibility by eliminating the security and political issues associated with carrying nuclear arms. It would be highly desirable, however, to formalize and verify these withdrawals, placing withdrawn weapons under jointly monitored, secure control, to preserve options for further cuts in the future

    Although the State of Israel has always been threatened from the sea, preparing for the threat was not an important priority for the state’s leaders, as reflected by the resources that were allocated to the navy. However, once long range missiles appeared in the naval arena (in the 1960s), it became clear that the navy’s vessels and the air force’s planes were not capable of coping with this challenge. In light of the current upheaval in the Arab world, these fears are far from illusory. Even ...

  9. Intersections of family homelessness, CPS involvement, and race in Alameda County, California.

    Science.gov (United States)

    Rodriguez, Jason M; Shinn, Marybeth

    2016-07-01

    The homelessness and child protective services (CPS) systems are closely linked. This study examines the patterns and sequence of families' involvement with homeless shelters and CPS, as well as whether involvement in each system predicts involvement in the other using linked administrative records for 258 families recruited in emergency shelters in Alameda County, California. More than half of families were reported to CPS at some point, but less than one-fifth ever had a report substantiated. Reports that were uninvestigated or unfounded increased in the months leading up to shelter entry and spiked immediately afterward, but substantiations and child removals increased only later. Shelter use before study entry was associated with CPS referrals and investigations after study entry, although not with substantiated cases or child removals. However, CPS involvement before study entry was not associated with returns to shelter after study entry. These results imply that an unsubstantiated report of neglect or abuse may serve as an early warning signal for homelessness and that preventive strategies aiming to affect both homeless and child protective systems should focus on reducing homelessness. CPS workers should evaluate families' housing needs and attempt to link families to appropriate resources. Black families were disproportionately referred to CPS after shelter entry after controlling for other family characteristics, but race was not associated with substantiations of neglect or abuse or with child removals. Findings lend modest support to human decision-making and institutional explanations of racial disproportionalities in CPS involvement, especially for reporters outside of the CPS system.

  14. Nuclear Naval Propulsion: A Feasible Proliferation Pathway?

    Energy Technology Data Exchange (ETDEWEB)

    Swift, Alicia L.

    2014-01-31

    There is no better time than now to close the loophole in Article IV of the Nuclear Non-proliferation Treaty (NPT) that excludes military uses of fissile material from nuclear safeguards. Several countries have declared their intention to pursue and develop naval reactor technology, including Argentina, Brazil, Iran, and Pakistan, while other countries such as China, India, Russia, and the United States are expanding their capabilities. With only a minority of countries using low enriched uranium (LEU) fuel in their naval reactors, it is possible that a state could produce highly enriched uranium (HEU) under the guise of a nuclear navy while actually stockpiling the material for a nuclear weapon program. This paper examines the likelihood that non-nuclear weapon states exploit the loophole to break out from the NPT and also the regional ramifications of deterrence and regional stability of expanding naval forces. Possible solutions to close the loophole are discussed, including expanding the scope of the Fissile Material Cut-off Treaty, employing LEU fuel instead of HEU fuel in naval reactors, amending the NPT, creating an export control regime for naval nuclear reactors, and forming individual naval reactor safeguards agreements.

  16. Decommissioning of naval nuclear ships

    International Nuclear Information System (INIS)

    During the next decade the two major nuclear powers will each have to decommission more than 100 naval nuclear vessels, in particular submarines. The problems connected with this task is considered in this report. Firstly the size of the task is considered, i.e. the number of nuclear vessels that has to be decommissioned. Secondly the reactors of these vessels, their fuel elements, their power level, the number of reactors per vessel and the amount of radioactivity to be handled are discussed. Thirdly the decommissioning procedures, i.e. The removal of fuel from the vessels, the temporary storage of the reactor fuel near the base, and the cleaning and disposal of the reactor and the primary circuit components are reviewed. Finally alternative uses of the newer submarines are briefly considered. It should be emphasizes that much of the detailed information on which this report is based, may be of dubious nature, and that may to some extent affect the validity of the conclusions of the report.

  17. Radioactivity around naval nuclear bases

    International Nuclear Information System (INIS)

    Between 12th July and 2nd August 1988, Greenpeace took sediment samples from around four Royal Navy bases in the United Kingdom. Faslane, where nuclear powered submarines are berthed; Devonport and Rosyth where refit work is carried out and Portsmouth where US and UK nuclear submarines often visit. Samples were also taken from the US Navy base at Holy Loch, Scotland, where nuclear powered ballistic missile submarines are based. The samples were analysed at St Bartholomew Hospital Medical School, London. Identical samples were provided to the MoD personnel at Faslane and Devonport on the date taken. The purpose of carrying out the sampling programme was to highlight the fact that publicly available statistics from Ministry of Agriculture Fisheries and Food (MAFF) are too limited in range, concentrating as they do merely on radioactive levels found between tides. The findings point to the necessity of monitoring subtidal as well as intertidal areas since levels of radioactivity found in the samples at Faslane and Holy Loch were four to nine times the figures published by MAFF. Until such time as nuclear power is no longer used at sea, it is the contention of Greenpeace that a more independent and comprehensive picture of the nature of radioactive contamination from around UK naval establishments must be obtained, than that presently available from MAFF.

    The Naval Research Laboratory (NRL) is involved in an active program of CSI flight experiments. The first CSI flight experiment of the Naval Research Laboratory, the Low Power Atmospheric Compensation Experiment (LACE) dynamics experiment, has successfully measured vibrations of an orbiting satellite with a ground-based laser radar. The observations, made on January 7, 8 and 10, 1991, represent the first ever measurements of this type. In the tests, a narrowband heterodyne CO2 laser radar, operating at a wavelength of 10.6 microns, detected vibration induced differential-Doppler signatures of the LACE satellite. Power spectral densities of forced oscillations and modal frequencies and damping rates of free-damped vibrations were obtained and compared with finite element structural models of the LACE system. Another manifested flight experiment is the Advanced Controls Technology Experiment (ACTEX) designed to demonstrate active and passive damping with piezo-electric (PZT) sensors and actuators. This experiment was developed under the management of the Air Force Phillips Laboratory with integration of the experiment at NRL. It is to ride as a secondary, or 'piggyback,' experiment on a future Navy satellite.

  3. Angular glint effects generation for false naval target verisimility requirements

    International Nuclear Information System (INIS)

    A stimulating problem in the generation of coherent countermeasures for high range resolution radar systems is the inclusion of angular glint effects in the preparation of the false target mask. Since angular glint is representative of extended naval targets, this inclusion increases the credibility factor of the decoy playback signal at the adversary radar-operator station. In this paper, the ability of an interferometric inverse synthetic aperture radar (InISAR) simulator to provide a proof of concept towards the clarification of this challenging task is ascertained. The solution consists of three novel vector representations of the generated data, which are proven to behave according to the laws of physics governing the glint phenomenon. The first depiction is the angular glint injection at the target which is followed by the representation of the wavefront distortion at the radar. A value-added time procession integration of the target in pure roll motion provides an expected by ISAR theory side-view image of the naval extended false target. The effectiveness of the proposed approach through verification and validation of the results by using the method of pictorial evidence is established. A final argument is raised on the usage of this software tool for actual obfuscation and deception actions for air defence at sea applications

    Buchanan, Emmakate MacQueen

    2005-01-01

    Summerson writes that, in the spirit of the Enlightenment, the notion of 'bienfaisance', literally meaning the desire to render society more reasonable and more humane, liberated the scope of both hospital and prison planning. Both types of institution housed people who were deprived of their freedom either by disability or by force of law; therefore, we find similarities in the disposition of space and in the degree of humanitarianism expressed in their outward appearance. This observation can be transferred to naval hospital design, where architecture was combined to fulfil a twofold purpose. The high walls, sturdy massing and pared-down details intimated a strict economy of means, but also a strong sense of gravitas and authority. This visual authoritarian character was fundamental to the identity of a naval hospital, for whilst the prime intention was to provide efficient medical care, an equally important consideration was to maintain discipline and prevent sailors from escaping.

    Modern warships ranging from Air Warfare Destroyers to Offshore Patrol Vessels (OPV) and Fast Patrol Boats have to deal with an ever increasing variety of threats, both symmetric and asymmetric, for self-protection. This last category has introduced new requirements for combat systems sensors and effectors: situation awareness in proximity of the own ship has become a priority, as well as the need for new, lethal or non-lethal effectors for timely and proportional response. Naval Combat Systems (CS) architects are then faced with an alternative: they can either use existing CS sensors, C2 and weapons, or else rely on new, specialized equipments. Both approaches have their pros and cons, with the cost issue not necessarily trivial to assess. In this paper, we present a multifunction system that is both a passive IRST (InfraRed Search and Track) sensor, designed to automatically detect and track air and surface threats, and an Electro Optical Director (EOD), capable of providing identification of objects as well as accurate 3D tracks. Following an introduction reviewing the design goals for the equipment, the EOMS NG processing architecture is described (Image & Tracking Processes). Then, system performances are presented for different scenarios provided from Field Tests.

    The clash between the United States and Japan in the Pacific from December 1942 to August 1945 presumably caused marine geohazards exceeding significantly many submarine earthquakes, explosive volcanic eruptions and tsunamis. Most significantly the most pronounced shift in Pacific Decadal Oscillation (PDO) took place within the shortest period of time ever observed, and when the Allies navies approached Japan's coast line two years later, winter air temperatures (December to February 1944/45) fell to the lowest level ever observed. The Naval War in the Pacific from 1943 - 1945 was not only devastating to man and material, but also substantially altered the structure of the sea surface layer down to 100 meter and more, with a subsequent impact on air temperatures, and PDO balance across the Northern Pacific. Until now the question has received little attention although it is obvious that a global rising temperature trend prior the early 1940s turned into a decreasing mode during the time when huge naval war activities took place across the oceans in the Northern Hemisphere that eventually lasted for three decades until the mid-1970s While the impact of screw driven vessels since their invention in the 19th Century on the sea surface structure is difficult to assess, and no investigations have been made yet . The naval war in the Pacific from 1943 - 1945 could be regarded as a huge scale 'field experiment' on manmade marine geohazards due to the suddenness, the magnitude and the intensity, penetrating the ocean to considerable depths. Naval operations and available sea and climate data need to be identified, linked, evaluated and discussed. What kind of impact did the Pacific War have on climate? It seems due time to pay attention to this issue.

  3. Risk Assessment for Tuzla Naval Base Breakwater

    In the applications of reliability-based risk assessment methodology in Turkey, only wave characteristics, tidal range, storm surge, wave set-up, and structural system parameters were included in the past. Tsunami risk was not considered as a major design parameter and thus, was not included in the computation. After a strong earthquake (Mw=7.4) occurred near the town of Golcuk, Izmit Bay, Western Turkey at 00:01 GMT on August 17, 1999, chaotic water movements were observed on the coast of the Marmara Sea. Rubble mound breakwaters demonstrated very little damage, as predicted by the reliability-based risk assessment model developed in this study for the Tuzla Naval Base. For determination of the probability of occurrence under design conditions, which is a function of storm waves, tidal range, storm surge, and tsunami height, the Monte Carlo simulation was interrelated with the βⅡ method. For the Tuzla Naval Base main breakwater, tsunami was not the key design parameter when compared to storm waves, however, in places with great seismic activity, tsunami risk can be significant depending on the probability of occurrence and the magnitude of the tsunami.

  4. Research at the Royal Naval College

    International Nuclear Information System (INIS)

    The Department of Nuclear Science and Technology at the Royal Naval College, Greenwich has the primary responsibility for the post-graduate training of the future operators of the Navy's pressurised water reactors. In addition, the Department offers a wide range of other nuclear oriented courses, ranging from an MSc in Reactor Technology, through courses in Health and Safety, Dockyard Engineering and Radiochemistry, and introductory courses in Nuclear Power and Submarine Propulsion. Although the Department's primary role is its training commitment, the need to conduct an ongoing program of research has become obvious. This paper is intended to present a brief review of the development of the research program, from the installation of the Jason Reactor in 1962. The early work was the result of specific development problems in the areas of reactor dynamics shielding and dosimetry. More recently, the Department has established, with internal and external funding, a Unit dedicated to research in Naval Nuclear Propulsion and its associated environmental problems. This is the Nuclear Marine Technology Unit and brings together the various programs under one body and provides a basis for several new sponsored research programs. (author)

  7. Sediment accumulation in San Leandro Bay, Alameda County, California, during the 20th century - A preliminary report

    International Nuclear Information System (INIS)

    Major changes made in the configuration of San Leandro Bay, Alameda County, California, during the 20th century have caused rapid sedimentation within parts of the Bay. Comparison of bathymetric surveys indicates that sedimentation in the vicinity of the San Leandro Bay channel averaged 0.7 cm/annum between 1856 and 1984. Lead-210 data collected at four shallow water sites east of the San Leandro Bay channel indicated that sedimentation rates have averaged between 0.06 and 0.28 cm/annum. Because bioturbation of bottom sediments cannot be discounted, better definition of this range in sedimentation rates would require measuring the activity of lead-210 on incoming sediments. In addition to sediment deposited in the vicinity of the San Leandro Bay channel and open, shallow areas to the east, 850,740 cu m of sediment was deposited between 1948 and 1983 in an area dredged at the mouth of San Leandro Creek. All available data indicate that between 1,213,000 and 1,364,000 cu m of sediment was deposited in San Leandro Bay between 1948 and 1983. Sediment yield data from an adjacent drainage basin, when combined with inventories of lead-210 and cesium-137, indicate that most of the sediment deposited in San Leandro Bay is coming from resuspension of bottom sediments or from erosion of marshes or shorelines of San Leandro or San Francisco Bay. 31 refs., 7 figs., 4 tabs

    Weber, W; Woollett, J

    2004-11-16

    Condor County Consulting on behalf of Lawrence Livermore National Laboratory (LLNL) has performed wet season surveys for listed branchiopods at Site 300, located in eastern Alameda County and western San Joaquin County. LLNL is collecting information for the preparation of an EIS covering ongoing explosives testing and related activities on Site 300. Related activities include maintenance of fire roads and annual control burns of approximately 607 hectares (1500 acres). Control burns typically take place on the northern portion of the site. Because natural branchiopod habitat is sparse on Site 300, it is not surprising that listed branchiopods were not observed during this 2001-2002 wet season survey. Although the site is large, a majority of it has topography and geology that precludes the formation of static seasonal pools. Even the relatively gentle topography of the northern half of the site contains few areas where water pools for more than two weeks. The rock outcrops found on the site did not provide suitable habitat for listed branchiopods. Most of the habitat available to branchiopods on the site is puddles that form in roadbeds and dry quickly. The one persistent pool on the site, the larger of the two modified vernal pools and the only one to fill this season, is occupied by two branchiopod species that require long-lived pools to reach maturity. In short, there is little habitat available on the site for branchiopods and most of the habitat present is generally too short-lived to support the branchiopod species that do occur at Site 300.

    2001-07-13

    The Naval Spent Nuclear Fuel Disposal Container System supports the confinement and isolation of waste within the Engineered Barrier System of the Monitored Geologic Repository (MGR). Disposal containers/waste packages are loaded and sealed in the surface waste handling facilities, transferred underground through the access drifts using a rail mounted transporter, and emplaced in emplacement drifts. The Naval Spent Nuclear Fuel Disposal Container System provides long term confinement of the naval spent nuclear fuel (SNF) placed within the disposal containers, and withstands the loading, transfer, emplacement, and retrieval operations. The Naval Spent Nuclear Fuel Disposal Container System provides containment of waste for a designated period of time and limits radionuclide release thereafter. The waste package maintains the waste in a designated configuration, withstands maximum credible handling and rockfall loads, limits the waste form temperature after emplacement, resists corrosion in the expected handling and repository environments, and provides containment of waste in the event of an accident. Each naval SNF disposal container will hold a single naval SNF canister. There will be approximately 300 naval SNF canisters, composed of long and short canisters. The disposal container will include outer and inner cylinder walls and lids. An exterior label will provide a means by which to identify a disposal container and its contents. Different materials will be selected for the waste package inner and outer cylinders. The two metal cylinders, in combination with the Emplacement Drift System, drip shield, and the natural barrier will support the design philosophy of defense-in-depth. The use of materials with different properties prevents a single mode failure from breaching the waste package. The inner cylinder and inner cylinder lids will be constructed of stainless steel while the outer cylinder and outer cylinder lids will be made of high-nickel alloy.

    Full Text Available In 1859 France completed the first ocean-going ironclad warship, «La Gloire», and changed the definition of naval power completely. Russia, as all the other Powers, found that her most powerful naval gun, the 60-pdr, was insufficient for modern warfare, and realized the future naval armament relied on heavy rifled artillery. Both the Army and Navy began purchasing such cannon from foreign providers until a suitable domestic weapon could be produced. The relationship between the Russian military and Krupp is well known. But there was another provided, the Blakely Ordnance Company in England sold many guns to the Army and Navy, beginning with 8-inch MLR in early 1863 to a large number of 9- and 11-inch guns. Deliveries began in November 1863 and continued until mid-1866. But no sources on the armament of Russian ships and fortresses mentions these guns. What happened to them is a mystery.

  1. Implementation Of Fiber Optics In U. S. Naval Combatants

    Science.gov (United States)

    Johnston, R. A.; Stewart, R. C.

    1987-12-01

    This paper describes a program wherein fiber optic technology was introduced into the U. S. Navy's AEGIS Cruisers. This program was sponsored and funded for the most part by Naval Sea Systems Command and represents the first significant effort involving naval vessels. Although specific to one ship class, the program achievements are applicable to most naval as well as commercial ships. The process of transitioning fiber optic technology from the laboratory or commercial sector to a military ship is described. The issues addressed and problems resolved during this transition are discussed. Some of the primary issues include transmission data rates, ship producibility and environmental concerns such as temperature extremes, shock, vibration, ionizing radiation, toxic materials, etc. Additionally, the advantages of fiber optic technology specific to U. S. Naval ships are explained. Of particular importance are the developments that evolved from the AEGIS Cruiser program. Developments include a unique cable design, junction boxes, connectors, a splice, emergency repair procedures, a remote motor control system, a torsionmeter system, and a family of sensors and switches. The overall program resulted in the installation of fiber optic systems on three U. S. Navy ships. These installation projects are described along with some of the lessons learned. The paper concludes that the past issues that prevented the use of fiber optic technology in naval ships have been addressed and resolved. Fiber optics has successfully been introduced into naval combatants in data transmission, control, and sensing applications. Normal producibility has been considered such that fiber optic systems have been installed in almost routine fashion by a commercial shipyard. Additionally, human factor considerations have resulted in little or no additional training being required for operational and maintenance personnel.

  11. Modeling the geomorphological impact on Alameda Creek, CA, and associated change in flood risk, due to the removal of Sunol and Niles Dams

    2008-12-01

    The Sunol and Niles Dams on Alameda Creek, CA, were removed in 2006 to improve fish passage. Though the total sediment storage in the reservoirs was estimated to be at no more than one-quarter of the mean annual sediment load of Alameda Creek, there was concern that a downstream sediment pulse resulting from dam removal would induce a transient water level increase in the flood control channel (FCC) requiring that costly channel dredging (done as a flood control measure) be carried out earlier than originally anticipated. To assess the impact of the dams" removal, the morphological evolution of the FCC over an 11-year period (Oct. 2003 to Oct. 2014) was simulated with MIKE 21C, a curvilinear 2-dimensional (2D) morphological model. Simulations of over a decade at very fine time steps were feasible due to recent parallelization of the model code. Nine scenarios were simulated covering three different reservoir scouring potentials (high, low, and none - the 'baseline' case) and three different future stream discharge patterns (wet, dry, historic). The channel bed evolution from these nine scenarios was examined to determine four points in time at which the impact of the additional reservoir sediments might pose the greatest increase in flood risk compared to the dams remaining in place (i.e. the no-scouring baseline cases). The channel bathymetries for these four cases plus the baselines were carried over to a 1D+2D hydrodynamic model (MIKE FLOOD) of the channel (1D) and floodplain (2D). The hydrodynamic flood model was run using the 100-yr, 500-yr, and FCC standard design hydrographs as input to determine if the additional sedimentation resulted in increased, or any, overtopping of the channel levees and consequent flooding. The study therefore provided quantification of the temporary impact on flooding induced by the dam removal.

  6. Challenges of Forward Naval Surgical Support for Maritime Forces.

    Science.gov (United States)

    Chong, Si Jack; Jiang, Lei; Chow, Wei-En

    2015-08-01

    The emphasis of naval operations has shifted from conventional naval warfare since World War II to Operations Other than War such as Peace Support Operations and Humanitarian Aid and Disaster Relief. Maritime forces are increasingly deployed in distant areas of operations such as the Somali Basin and Gulf of Aden for longer durations, in a possibly higher threat environment against nonconventional threats such as in counter piracy operations. There is therefore a need to balance the challenges of providing adequate forward naval surgical support with limitations in medical manpower, logistics as well as the need for a suitable surgical platform for these deployments. This article aims to share the Republic of Singapore Navy's experience in overcoming some of these challenges. This includes the ability to deploy surgical containers onboard the Landing Ship Tank and Civil Resource vessels, and the ability to convert existing spaces onboard the endurance class Landing Ship Tank and other platforms such as the formidable class Frigate into surgical facilities. The key success factors such as the development of deep expertise in naval operational medicine, operationalization of third generation surgical stores, and enhanced interoperability among maritime forces will also be highlighted.

    2015-11-01

    Full Text Available Background The health of military families including factors affecting the productivity and satisfaction of employees and armed forces are of great importance. Objectives This study aimed to compare the public health and scale corresponding to the four groups of military families (surface, subsurface, marines, and pilots. Patients and Methods The sample in this study included 200 families of naval officers who were selected through stratified sampling method Results The results showed that the officers’ families of shallow subsurface, marines and pilots differed in terms of public health. The findings also showed that in families of small-scale pilot officers, subscales physical symptoms, sleep disturbances, symptoms of anxiety, and depression symptoms subscale scores were higher. There was a difference in the marital satisfaction and its components among different families of the naval officers. To explain the findings, we had to note that the mean of marital satisfaction and its subscales in the three groups of naval families (i.e. surface forces, submarine forces and marine forces was different from the families of the naval pilot officers. Consequently, since the group of naval pilot families had the highest level of difference both in the general variable of marital satisfaction and its subscales, it is necessary to study this subject further in future researches. Conclusions Given the importance of the military in safeguarding our borders, the study found that public health is relatively good in the four studied forces, but the pilot families should pay some more attention to their health to achieve improved public health.

  17. Structural response of reduced scale naval structures under impact tests

    Directory of Open Access Journals (Sweden)

    Calle M.A.G.

    2014-01-01

    Full Text Available Scaled models are important in naval engineering since actual ship size makes too expensive to test prototypes. However, the analysis of ship collision events employing naval structures in reduced scale is not an ordinary ship research area. The aim of this work is to create the basis for a posterior similarity study by analysing reduced scale ship structures submitted to impact loads. Two basic naval structures, commonly found in the construction of large ships, were considered for this study: a T cross-section beam submitted to a mid-span impact test and a double plate panel with inner cross reinforcement also submitted to a central impact load. These models were made in a reduced scale of 1:100. The experimental material characterization was also carried out in this work, including the evaluation of the stress strain curve under quasi static conditions, the strain rate sensitivity and the structural failure using three criteria developed particularly for numerical modelling of ship collision by other authors.

  18. Forty years on: the UK Naval nuclear propulsion programme

    Energy Technology Data Exchange (ETDEWEB)

    Hill, R.

    1997-03-01

    The naval nuclear power propulsion programme in the United Kingdom had its origins in the appointment of navy personnel to the Atomic Energy Research Establishment at Harwell in 1946. Atomic power was seen from the outset to be particularly applicable to submarines. It was not till 1955 that work started in earnest, however, and a naval section was established at Harwell. A land-based prototype was seen to be essential and Dounreay was selected as the site for its development. A PWR reactor system was chosen and submarine plant initial criticality by mid-1962 was the objective. However, an agreement with the USA in 1958 to use an American propulsion plant meant that it was possible to build and launch HMS Dreadnought by October 1960. Subsequent submarines were built to all-British designs and the Dounreay prototype contributed for over 35 years to their successful evolution. These submarines, which culminated in the Trafalgar class, are briefly described. In the early 1980s the decision was taken to replace the Polaris strategic weapon system by the Trident system which required a larger and more powerful submarine. The original Dounreay prototype was too small to be useful for the development of the Trident submarine and a new prototype was installed at Dounreay at the Naval Nuclear Reactor Test Establishment.

  19. 1996 environmental monitoring report for the Naval Reactors Facility

    International Nuclear Information System (INIS)

    The results of the radiological and nonradiological environmental monitoring programs for 1996 at the Naval Reactors Facility (NRF) are presented in this report. The NRF is located on the Idaho National Engineering and Environmental Laboratory and contains three naval reactor prototypes and the Expended Core Facility, which examines developmental nuclear fuel material samples, spent naval fuel, and irradiated reactor plant components/materials. The results obtained from the environmental monitoring programs verify that releases to the environment from operations at NRF were in accordance with state and federal regulations. Evaluation of the environmental data confirms that the operation of NRF continues to have no adverse effect on the quality of the environment or the health and safety of the general public. Furthermore, a conservative assessment of radiation exposure to the general public as a result of NRF operations demonstrated that the dose received by any member of the public was well below the most restrictive dose limits prescribed by the Environmental Protection Agency (EPA) and the Department of Energy (DOE)

  4. Undergraduate courses for enhancing design ability in naval architecture

    Science.gov (United States)

    Lee, Kyu-Yeul; Ku, Namkug; Cha, Ju-Hwan

    2013-09-01

    Contemporary lectures in undergraduate engineering courses typically focus on teaching major technical knowledge-based theories in a limited time. Therefore, most lectures do not allow the students to gain understanding of how the theories are applied, especially in Naval Architecture and Ocean Engineering departments. Shipyards require students to acquire practical ship design skills in undergraduate courses. To meet this requirement, two lectures are organized by the authors; namely, "Planning Procedure of Naval Architecture & Ocean Engineering" (PNAOE) and "Innovative Ship Design" (ISD). The concept of project-based and collaborative learning is applied in these two lectures. In the PNAOE lecture, sophomores receive instruction in the designing and building of model ships, and the students' work is evaluated in a model ship contest. This curriculum enables students to understand the concepts of ship design and production. In the ISD lecture, seniors learn how to develop their creative ideas about ship design and communicate with members of group. They are encouraged to cooperate with others and understand the ship design process. In the capstone design course, students receive guidance to facilitate understanding of how the knowledge from their sophomore or junior classes, such as fluid mechanics, statics, and dynamics, can be applied to practical ship design. Students are also encouraged to compete in the ship design contest organized by the Society of Naval Architects of Korea. Moreover, the effectiveness of project-based and collaborative learning for enhancing interest in the shipbuilding Industry and understanding the ship design process is demonstrated by citing the PNAOE and ISD lectures as examples.

  6. Remote sensing of evaporation ducts for Naval warfare

    Science.gov (United States)

    Geernaert, G. L.

    1989-11-01

    Areas critical to naval operations are the prediction and application of atmospheric refractivity gradients. This report describes the use of the evaporation duct over the ocean and a plan for obtaining information about the evaporation duct by space-borne sensors. There has been little research on the theory and modeling of lower atmospheric refractivity, particularly evaporation ducts over a nonhomogeneous ocean over the past five decades. Much is known about surface layer similarity theory and propagation model techniques, but little attention has been placed on the spatial variabilities in the turbulent propagation medium (such as the atmospheric surface layer) in regions of strategic Navy interest. These regions include the coastal shelf, Gulf Stream, marginal ice zone, and those places where sharp sea surface temperature fronts exist. For tomorrow's Navy, using remote sensing techniques to infer evaporative and tropospheric ducts are a requirement. Although research efforts on ducts must couple the tropospheric and surface layer components, this report summarizes the state of the art for the evaporative duct and assess the potential of new and future results on improving next generation naval warfare capabilities.

    Research work in smart, unmanned limbed vehicles for naval warfare applications performed during the latter part of FY76 and FY76T by the Special Studies Group of the LLL Physics Department for the Office of Naval Research is reported. Smart water-traversing limbed remotely navigated vehicles are interesting because: they are the only viable small vehicle usable in high sea states; they are small and work on the ocean surface, they are much harder to detect than any other conventional craft; they have no human pilot, are capable of high-g evasion, and will continue to operate after direct hits that would have crippled a human crew; they have the prospect of providing surface platforms possessing unprecedented speed and maneuverability; unlike manned information-gathering craft, they impose almost no penalty for missions in excess of 10 hours (no need to rotate shifts of crewmen, no food/lavatory requirements, etc.) and, in their ''loitering mode'', waterbugs could perhaps perform their missions for days to weeks; they are cheap enough to use for one-way missions; they are mass-producible; they are inherently reliable--almost impossible to sink and, in the event of in-use failure, the vehicle will not be destroyed; they maximally exploit continuing technological asymmetries between the U.S. and its potential opponents; and they are economically highly cost-effective for a wide spectrum of Navy missions.

  8. A naval nuclear port: the costs to Rosyth

    International Nuclear Information System (INIS)

    This report is part of Greenpeace's Nuclear Free Seas Campaign. Previous publications have detailed the global inventory of the growing naval nuclear arsenals, the increasingly dangerous maritime strategies, and the UK's role in the naval nuclear arms race. The purpose of this research is to bring to the public's attention the environmental dangers that threaten Rosyth as a result of its role in the infrastructure that supports the UK's nuclear navy. The dockyard is used for replacing the fuel (refuelling) and maintenance (refitting) of nuclear powered submarines. It is also home port to four Type 42 Destroyers which are capable of carrying nuclear depth bombs for their helicopters. The presence in Rosyth of HMS Dreadnought, the first of Britain's nuclear powered submarines to be decommissioned, raises the additional question of the final destination of this and the nine other nuclear submarines scheduled to have their nuclear fuel removed in the next 12 years. The report considers the likelihood of a serious accident involving a nuclear reactor or nuclear weapon in Rosyth 'Public Safety Scheme' which is supposedly designed to cope with a nuclear reactor accident. The study looks at the dangers inherent in the 'normal' activities of nuclear powered submarines in Rosyth. It considers the adequacy of the present monitoring of the radiation that comes with their presence, looks at the health implications for workers and examines the high level of leukaemia in the under 25 age group that have been recorded in the area.

  9. Vitrification of contaminated soils from the Charleston Naval Complex

    International Nuclear Information System (INIS)

    Demonstration melting tests for vitrifying chrome- and lead-bearing wastes from the Charleston Naval Complex, and organic-contaminated dredging spoils from the Ashley River (part of the greater Charleston Harbor), were conducted in a 3-phase AC, graphite electrode arc furnace located at the Albany Research Center (ALRC) of the U.S. Department of Energy (DOE). These tests were conducted in cooperation with the Center for Engineering Ceramic Manufacturing (CECM) of Clemson University, and AJT Enterprises, Inc., of Charleston, South Carolina, and were funded by the DOE Office of Environmental Restoration. The two waste streams were composited into separate furnace feed mixtures by blending and agglomeration with readily available industrial minerals. Over 11,340 kg (25,000 lb) of feed was processed during the demonstration melting test, at feed rates up to 523 kg/h (1,150 lb/h). Continuous feeding and glass tapping was achieved for both the dredging spoils feed mixture and the naval complex mixture. Roughly 85% of all feed reported to the glass products, which readily passed the Environmental Protection Agency (EPA) Toxicity Characteristic Leaching Procedure (TCLP). ASTM aggregate tests using the vitrified aggregate in concrete and asphaltic cements indicated a potential for utilization of these materials in concentrations from 5-15% of the total aggregate, without negative impact on the mix. Toxicological tests performed on the glass products found that this material appears to be nonhazardous and its use is not likely to result in a public health risk

  2. Naval application of battery optimized reactor integral system

    International Nuclear Information System (INIS)

    Past civilian N.S. Savanna (80 MWth), Otto-Hahn (38 MWth) and Mutsu (36 MWth) experienced stable operations under various sea conditions to prove that the reactors were stable and suitable for ship power source. Russian nuclear icebreakers such as Lenin (90 MWth x2), Arukuchika (150 MWth x2) showed stable operations under severe conditions during navigation on the Arctic Sea. These reactor systems, however, should be made even more efficient, compact, safe and long life, because adding support from the land may not be available on the sea. In order to meet these requirements, a compact, simple, safe and innovative integral system named Naval Application Vessel Integral System (NAVIS) is being designed with such novel concepts as a primary liquid metal coolant, a secondary supercritical carbon dioxide (SCO2) coolant, emergency reactor cooling system, safety containment and so on. NAVIS is powered by Battery Optimized Reactor Integral System (BORIS). An ultra-small, ultra-long-life, versatile-purpose, fast-spectrum reactor named BORIS is being developed for a multi-purpose application such as naval power source, electric power generation in remote areas, seawater desalination, and district heating. NAVIS aims to satisfy special environment on the sea with BORIS using the lead (Pb) coolant in the primary system. NAVIS improves the economical efficiency resorting to the SCO2 Brayton cycle for the secondary system. BORIS is operated by natural circulation of Pb without needing pumps. The reactor power is autonomously controlled by load-following operation without an active reactivity control system, whereas B4C based shutdown control rod is equipped for an emergency condition. SCO2 promises a high power conversion efficiency of the recompression Brayton cycle due to its excellent compressibility reducing the compression work at the bottom of the cycle and to a higher density than helium or steam decreasing the component size. Therefore, the SCO2 Brayton cycle efficiency

  3. An IKBS approach to surveillance for naval nuclear submarine propulsion

    International Nuclear Information System (INIS)

    This Paper describes work being carried out to develop an intelligent knowledge-based system (IKBS) for use in the surveillance of naval nuclear submarine propulsion plant. In recent years, modern process plants have increased automation and installed surveillance equipment while reducing the level of manpower operating and monitoring the plant. As a result, some of the local watchkeeping tasks have been transferred to control room operators, and the data reduction and warning filtering expertise inherent in local plant operators has been lost, while an additional workload has been placed upon operators. The surveillance systems installed to date have therefore been less usable than anticipated. The solution being achieved for submarine power plant is to introduce IKBS into surveillance to replace lost expertise and return to a situation in which operators receive small amounts of high quality information rather than large amounts of low quality information.

    This paper describes the classification function of naval targets performed by an infrared camera (IR) and an electro-optical camera (EO) that operate in a more complex multisensor system for the surveillance of a coastal region. The following naval targets are considered: high speed dinghy, motor boat, fishing boat, oil tanker. Target classification is automatically performed by exploiting the knowledge of the sensor confusion matrix (CM). The CM is analytically computed as a function of the sensor noise features, the sensor resolution, and the dimension of the involved image database. For both the sensors, a database of images is generated exploiting a three-dimensional (3D) Computer Aided Design (CAD) of the target, for the four types of ship mentioned above. For the EO camera, the image generation is simply obtained by the projection of the 3D CAD on the camera focal plane. For the IR images simulation, firstly the surface temperatures are computed using an Open-source Software for Modelling and Simulation of Infrared Signatures (OSMOSIS) that efficiently integrates the dependence of the emissivity upon the surface temperature, the wavelength, and the elevation angle. The software is applicable to realistic ship geometries. Secondly, these temperatures and the environment features are used to predict realistic IR images. The local decisions on the class are made using the elements of the confusion matrix of each sensor and they are fused according to a maximum likelihood (ML) rule. The global performance of the classification process is measured in terms of the global confusion matrix of the integrated system. This analytical approach can effectively reduce the computational load of a Monte Carlo simulation, when the sensors described here are introduced in a more complex multisensor system for the maritime surveillance.

  14. Improvement of operational safety of dual-purpose transport packaging set for naval SNF in storage

    International Nuclear Information System (INIS)

    Available in abstract form only. Full text of publication follows: In recent ten years a new technology of management of irradiated nuclear fuel (SNF) at the final stage of fuel cycle has been intensely developing on a basis of a new type of casks used for interim storage of SNF and subsequent transportation therein to the place of processing, further storage or final disposal. This technology stems from the concept of a protective cask which provides preservation of its content (SNF) and fulfillment of all other safety requirements for storage and transportation of SNF. Radiation protection against emissions and non-distribution of activity outside the cask is ensured by physical barriers, i.e. all-metal or composite body, shells, inner cavities for irradiated fuel assemblies (SFA), lids with sealing systems. Residual heat release of SFA is discharged to the environment by natural way: through emission and convection of surrounding air. By now more than 100 dual purpose packaging sets TUK-108/1 are in operation in the mode of interim storage and transportation of SNF from decommissioned nuclear powered submarines (NPS). In accordance with certificate, spent fuel is stored in TUK-108/1 on the premises of plants involved in NPS dismantlement for 2 years, whereupon it is transported for processing to PO Mayak. At one Far Eastern plant Zvezda involved in NPS dismantlement there arose a complicated situation due to necessity to extend period of storage of SNF in TUK- 108/1. To ensure safety over a longer period of storage of SNF in TUK-108/1 it is essential to modify conditions of storage by removing of residual water and filling the inner cavity of the cask with an inert gas. Within implementation of the international 1.1- 2 project Development of drying technology for the cask TUK-108/1 intended for naval SNF under the Program, there has been developed the technology of preparation of the cask for long-term storage of SNF in TUK-108/1, the design of a mobile TUK-108

    The Naval Petroleum and Oil Shale Reserves (NPOSR) produces crude oil and associated hydrocarbons from the Naval Petroleum Reserves (NPR) numbered 1, 2, and 3, and the Naval Oil Shale Reserves numbered 1, 2, and 3 in a manner to achieve the greatest value and benefits to the United States taxpayer. NPOSR was established by a series of Executive Orders in the early 1900s as a future source of liquid fuels for the military. NPOSR remained largely inactive until Congress, responding to the Arab oil embargo of 1973-74, passed the Naval Petroleum Reserves Production Act of 1976. The law authorized production for six years. Thereafter, NPOSR production could be reauthorized by the President in three-year increments. Since enactment of the law, every President has determined that continuing NPOSR production is in the nation`s best interest. NPOSR currently is authorized to continue production through April 5, 2000.

  2. Weldability and Strength Recovery of NUCu-140 Advanced Naval Steel

    Science.gov (United States)

    Bono, Jason T.

    NUCu-140 is a ferritic copper-precipitation strengthened steel that is a candidate material for use in many naval and structural applications. Previous work has shown that the heat-affected zone (HAZ) and fusion zone (FZ) of NUCu-140 exhibit softening that is due to dissolution of the copper-rich precipitates. This study aims to recover the FZ and HAZ strength by re-precipitation of the copper-rich precipitates through either multiple weld passes or an isothermal post-weld heat treatment (PWHT). The potential use of multiple thermal cycles was investigated with HAZ simulations using a Gleeble thermomechanical simulator. The HAZ simulations represented two weld thermal cycles with different combinations of peak temperatures during the initial and secondary weld passes. To investigate the potential for a PWHT for strength recovery, gas tungsten arc weld (GTAW) samples were isothermally heated for various times and temperatures. Microhardness measurements revealed no strength recovery in the multipass HAZ samples. The time dependent precipitate characteristics were modeled under the HAZ thermal cycle conditions, and the results showed that the lack of strength recovery could be attributed to insufficient time for re-precipitation during the secondary weld pass. Conversely, full strength recovery in the HAZ was observed in the isothermally heat treated samples. Atom-probe tomography (APT) analysis correlated this strength recovery to re-precipitation of the copper-rich precipitates during the isothermal PWHT. The experimental naval steel known as NUCu-140 and an established naval steel HSLA-100 were subjected to stress-relief cracking (SRC) and hot-ductility testing to assess their relative cracking susceptibilities during the welding process and post weld heat treatment. NUCu-140 exhibited a longer time-to-failure (TTF) and a lower temperature of minimum TTF during SRC testing when compared to HSLA-100, indicating better resistance to SRC for the NUCu-140 steel. The

  9. Renewable Energy Optimization Report for Naval Station Newport

    Energy Technology Data Exchange (ETDEWEB)

    Robichaud, R.; Mosey, G.; Olis, D.

    2012-02-01

    In 2008, the U.S. Environmental Protection Agency (EPA) launched the RE-Powering America's Land initiative to encourage the development of renewable energy (RE) on potentially contaminated land and mine sites. As part of this effort, EPA is collaborating with the U.S. Department of Energy's (DOE's) National Renewable Energy Laboratory (NREL) to evaluate RE options at Naval Station (NAVSTA) Newport in Newport, Rhode Island. NREL's Renewable Energy Optimization (REO) tool was utilized to identify RE technologies that present the best opportunity for life-cycle cost-effective implementation while also serving to reduce energy-related carbon dioxide emissions and increase the percentage of RE used at NAVSTA Newport. The technologies included in REO are daylighting, wind, solar ventilation preheating (SVP), solar water heating, photovoltaics (PV), solar thermal (heating and electric), and biomass (gasification and cogeneration). The optimal mix of RE technologies depends on several factors including RE resources; technology cost and performance; state, utility, and federal incentives; and economic parameters (discount and inflation rates). Each of these factors was considered in this analysis. Technologies not included in REO that were investigated separately per NAVSTA Newport request include biofuels from algae, tidal power, and ground source heat pumps (GSHP).

    Murray, K M; Johnson, W B

    2001-10-01

    There are relatively few studies regarding factors that predict success among female midshipmen at the U.S. Naval Academy (USNA). This study examined the personality characteristics of 1,568 women admitted to USNA between 1988 and 1996 to evaluate whether personality type was predictive of success vs. attrition. Participants completed the Myers-Briggs Type Indicator as well as a demographic questionnaire upon admission. Indicators of performance were gathered at graduation. Results indicated that most women at USNA are extroverts. Extroverted-Sensing-Thinking-Judging types were more likely to graduate, whereas Feeling and Perceiving themes were associated with dropping out. Previous military service and higher Scholastic Aptitude Test Math scores were also predictive of success at USNA. In general, the Myers-Briggs Type Indicator was not a good predictor of academic or military success at USNA. Among women who graduate, Scholastic Aptitude Test (Verbal and Math) scores appear to be the best predictors of both academic and military ratings. PMID:11603241

  11. Distributed energy resources at naval base ventura county building 1512

    International Nuclear Information System (INIS)

    This paper reports the findings of a preliminary assessment of the cost effectiveness of distributed energy resources at Naval Base Ventura County (NBVC) Building 1512. This study was conducted in response to the base's request for design assistance to the Federal Energy Management Program. Given the current tariff structure there are two main decisions facing NBVC: whether to install distributed energy resources (DER), or whether to continue the direct access energy supply contract. At the current effective rate, given assumptions about the performance and structure of building energy loads and available generating technology characteristics, the results of this study indicate that if the building installed a 600 kW DER system with absorption cooling and heat capabilities chosen by cost minimization, the energy cost savings would be about 14 percent, or $55,000 per year. However, under current conditions, this study also suggests that significant savings could be obtained if Building 1 512 changed from the direct access contract to a SCE TOU-8 (Southern California Edison time of use tariff number 8) rate without installing a DER system. At current SCE TOU-8 tariffs, the potential savings from installation of a DER system would be about 4 percent, or $15,000 per year

    1990-07-01

    Data Systems Engineering Organization (DSEO) personnel developed a prototype computer aided instruction CAI system for the Naval Aviation Logistics Data Analysis (NALDA) system. The objective of this project was to provide a CAI prototype that could be used as an enhancement to existing NALDA training. The CAI prototype project was performed in phases. The task undertaken in Phase I was to analyze the problem and the alternative solutions and to develop a set of recommendations on how best to proceed. The findings from Phase I are documented in Recommended CAI Approach for the NALDA System (Duncan et al., 1987). In Phase II, a structured design and specifications were developed, and a prototype CAI system was created. A report, NALDA CAI Prototype: Phase II Final Report, was written to record the findings and results of Phase II. NALDA CAI: Recommendations for an Advanced Instructional Model, is comprised of related papers encompassing research on computer aided instruction CAI, newly developing training technologies, instructional systems development, and an Advanced Instructional Model. These topics were selected because of their relevancy to the CAI needs of NALDA. These papers provide general background information on various aspects of CAI and give a broad overview of new technologies and their impact on the future design and development of training programs. The paper within have been index separately elsewhere.

  13. Prometheus Project Reactor Module Final Report, For Naval Reactors Information

    International Nuclear Information System (INIS)

    The Naval Reactors Prime Contractor Team (NRPCT) led the development of a power plant for a civilian nuclear electric propulsion (NEP) system concept as part of the Prometheus Project. This report provides a summary of the facts, technical insights, and programmatic perspectives gained from this two-year program. The Prometheus Project experience has been extensively documented to better position the US for future space reactor development. Major Technological and engineering challenges exist to develop a system that provides useful electric power from a nuclear fission heat source operating in deep space. General issues include meeting mission requirements in a system that has a mass low enough to launch from earth while assuring public safety and remaining safely shutdown during credible launch accidents. These challenges may be overcome in the future if there is a space mission with a compelling need for nuclear power to drive development. Past experience and notional mission requirements indicate that any useful space reactor system will be unlike past space reactors and existing terrestrial reactors

    The fourth United States Naval Observatory (USNO) CCD Astrograph Catalog, UCAC4 was released in August 2012 (double-sided DVD and CDS data center Vizier catalog I/322). It is the final release in this series and contains over 113 million objects; over 105 million of them with proper motions. UCAC4 is an updated version of UCAC3 with about the same number of stars also covering all-sky. Bugs were fixed, Schmidt plate survey data were avoided, and precise 5-band photometry were added. Astrograph observations have been supplemented for bright stars by FK6, Hipparcos and Tycho-2 data to compile a UCAC4 star catalog complete to about magnitude R = 16. Epoch 1998 to 2004 positions are obtained from observations with the 20 cm aperture USNO Astrograph's red lens, equipped with a 4k by 4k CCD. Mean positions and proper motions are derived by combining these observations with over 140 ground- and space-based catalogs, including Hipparcos/Tycho and the AC2000.2, as well as unpublished measures of over 5000 plates from ...

    2014-03-01

    Full Text Available This paper describes the effect of pod propulsor attachment to the existing Naval Vessel hull form which was designed for conventional propulsor in aspects of resistance and motion characteristics. These investigations were carried out on a 3.0 m model by experimental works in the towing tank 120m x 4m x 2.5m at the Marine Technology Centre (MTC, Universiti Teknologi Malaysia (UTM. The basis ship chosen for this study is Sealift class type MPCSS (Multi Purpose Command Support Ship. In this study, the design for the new pod propulsor is based on a proven design and scaled down to suit this type of hullform accordingly. This paper describes the resistance comparison between bare and podded hulls in calm water as well in waves. The seakeeping test for hull with and without pod in regular waves at service speed of 16.8 knots were carried out at wavelength to model length ratio, Lw/Lm between 0.2 and 1.2. The outcomes from this experimental works on hull with and without pod were compared.

    2014-03-01

    Full Text Available O alcoolismo entre os militares passou a ser objeto de atenção especial na Marinha do Brasil a partir da criação do Centro de Dependência Química em 1997. Este estudo se desenvolveu a partir do método etnográfico, através da observação participante em 2010, no decorrer de 24 sessões, em dois grupos terapêuticos, cada qual composto por cerca de dez integrantes. Os registros foram feitos em um diário de campo após as sessões grupais. Os resultados apontaram que existe uma importante influência de fatores socioculturais na produção de seu alcoolismo. Constatou-se que o beber a bordo é uma tradição aprendida, considerando que existem: oportunidades de beber e o fácil acesso a bebidas alcoólicas; normas favoráveis que apoiam o consumo, inclusive no ambiente de trabalho; e tradições navais que, de forma contínua e sutil, difundem crenças e mitos sobre a inquestionável presença do álcool na vida naval. Enfim, a Marinha brasileira tem um posicionamento ambivalente que, de forma alternada, estimula e proíbe o consumo de etílicos a bordo, aplicando medidas administrativas e punitivas, sem critérios claros. Com efeito, modos de consumir bebidas, geralmente em grupo, encontram-se associados à execução das tarefas marinheiras, facilitando a produção da dependência do álcool.

    Science.gov (United States)

    Wiegmann, D A; Shappell, S A

    1999-12-01

    The present study examined the role of human error and crew-resource management (CRM) failures in U.S. Naval aviation mishaps. All tactical jet (TACAIR) and rotary wing Class A flight mishaps between fiscal years 1990-1996 were reviewed. Results indicated that over 75% of both TACAIR and rotary wing mishaps were attributable, at least in part, to some form of human error of which 70% were associated with aircrew human factors. Of these aircrew-related mishaps, approximately 56% involved at least one CRM failure. These percentages are very similar to those observed prior to the implementation of aircrew coordination training (ACT) in the fleet, suggesting that the initial benefits of the program have not persisted and that CRM failures continue to plague Naval aviation. Closer examination of these CRM-related mishaps suggest that the type of flight operations (preflight, routine, emergency) do play a role in the etiology of CRM failures. A larger percentage of CRM failures occurred during non-routine or extremis flight situations when TACAIR mishaps were considered. In contrast, a larger percentage of rotary wing CRM mishaps involved failures that occurred during routine flight operations. These findings illustrate the complex etiology of CRM failures within Naval aviation and support the need for ACT programs tailored to the unique problems faced by specific communities in the fleet.

    2014-05-01

    Exploration for natural resources in the seabed of the Indian Ocean was undertaken by the German government institution of earth sciences and resources ("Bundesanstalt für Geowissenschaften und Rohstoffe", BGR) in November 2012. To provide for the medical safety of crew and scientists, a cooperation between the BGR and the trauma department of the Hannover Medical School was established. Research by physicians accompanying the naval expedition revealed that medical consultations mainly occur because of respiratory infections, abdominal discomfort, genitourinary discomfort and seasickness, with the rate of traumas being between 31% and 41%. Di Giovanna et al. stated that 97% of all emergencies on cruise ships are not critical and only 3% need an immediate emergency medical intervention. Consultations were already performed on the mainland prior to departure and included minor traumas due to non-appropriate footwear, otitis and respiratory infections. Seasickness was the main reason for consultation during the first days at sea. Strong seas resulted in some bruises. Minor injuries and foreign body injuries to the hands and feet also required consultation. First-degree sunburns resulted from exposure to the sun, while air-conditioning caused rhinosinusitis and conjunctivitis. A special consultation was a buccal splitting of tooth 36. An immediate emergency medical intervention was not necessary due to the relative low level of pain for the patient; however, due to the risk of further damage caused by nocturnal bruxism, a protective splint was formed using a small syringe. Other reasons for consultation were similar to those reported in the general literature. Medical activities at exotic locations may create the vision of a holiday character at first; however, intensive planning and preparation are needed. We recommend contacting police, customs, the federal institute for drugs and medical devices as well as the labour inspectorate, preferably in both the originating

  9. THE SYSTEM OF NAVAL EDUCATION IN KAISER GERMANY IN LATE 19th - EARLY 20th CENTURIES

    Directory of Open Access Journals (Sweden)

    Stanislav Nikolaevich Sinegubov

    2015-01-01

    Full Text Available The article gives a brief description of the system of naval education in Imperial Germany, which was formed in the late 19th century, highlights its advantages enhancing the high level of training specialists for the new fleet which was constructed in the country. The emphasis is on the process of staffing the non-commissioned officers’ corps on the basis of the sea cadets’ school. There was a great need for this educational institution to develop the Navy of the II Reich. The authorities encouraged a big annual enrollment of sea cadets introducing a wide range of social benefits, such as: free-of-charge education, full governmental support during the period of studies, good professional training that would guarantee not only job on a warship, but also career growth in future. Another important attractive aspect was that students were constantly under the control of officers who raised their wards in traditional moral values. All this attracted to naval schools young people, particularly from socially vulnerable strata of German society. The article considers special features of training and educating future officers at the Naval College and the Naval Academy in Kiel, which already had the elite character.

  7. The Nuclear Department, Royal Naval School of Marine Engineering - Provision of nuclear education and training to the naval nuclear propulsion programme and beyond

    International Nuclear Information System (INIS)

    Full text: The Nuclear Department (ND) of the Royal Naval School of Marine Engineering was formed within HMS SULTAN on 1 April 2001, following the integration of SULTAN's existing Nuclear Training Group and the Department of Nuclear Science and Technology, relocated from the (old) Royal Naval College Greenwich, London in October 1998. Both groups have a distinguished history with officers courses established at Greenwich in 1959 and ratings training established at HMS SULTAN in 1963. This collocation of nuclear systems' training, academics, and research placed, for the first time, the majority of Naval Nuclear Propulsion Programme (NNPP) shore based education and training on the one site. As systems training and education in nuclear reactor technology are integral to most courses offered by the Department, the integration enhanced aspirations to establish a centre of excellence in nuclear engineering within the Royal Navy School of Marine Engineering, which is part of the Naval Recruiting and Training Agency. The ND is also an Associated Institution of the University of Surrey with which it has had an alliance for almost 20 years. The Department's primary purpose is to provide education and training for all naval and civilian personnel appointed to the NNPP and its secondary purpose is to provide research, consultancy and expert advice in support of the Programme. With over 40 years proven experience in the provision of high quality nuclear education and systems training the ND presently offers over 45 scheduled courses in all key disciplines, from 'cradle to grave', to a broad group of key customers. Five academic courses attract post-graduate qualifications, that are validated by the University of Surrey, whilst the majority of ND's NNPP systems training courses are necessary prerequisites for both officers and ratings in order to qualify as nuclear submarine reactor and propulsion plant watch-keepers. The ND has a number of facilities and equipments that support

Real-time data, climatologies, coupled air/ocean models, and large scale computers are the essential components of the Navy's system for providing the war fighters with the performance predictions and tactical decision aids they need to operate safely and efficiently. In peacetime, these oceanographic predictions are important for safety of navigation and flight. The paucity and uneven distribution of real-time data mean we have to fall back on climatology to provide the basic data to operate our models. The Navy is both a producer and user of climatologies; it provides observations to the national archives and in turn employs data from these archives to establish data bases. Suggestions for future improvements to ocean climate data are offered.

  11. The RES Reactor. A test reactor for the French naval propulsion

    International Nuclear Information System (INIS)

    In the Cadarache nuclear research centre the French Atomic Energy Commission (CEA) operates, with the support of TECHNICATOME as nuclear operator, the experimental facilities which are necessary for the French naval propulsion program. Since the sixties these facilities have brought a large contribution to the development and to the technical support for the nuclear propulsion; they have been used also to train the French Navy operators. The last experimental reactor, the RNG, is now at the end of its life cycle after thirty years of a profitable operation. A replacement reactor is needed to sustain any evolution of the naval propulsion reactors as well as to guarantee a safe operation and a high level of availability of the existing onboard reactors. The aim of the RES program is namely to build such a test facility. Its construction program started in 2003. By the year 2009 the RES reactor will take over the mission of the RNG. We present hereafter: - A brief history of the French experimental reactors built in support to the naval propulsion, - The needs of the naval propulsion and the related objectives of the RES program, - The corresponding architecture and main characteristics of the RES facility, - The current status of the RES construction. The contents of the paper is as follows: 1. Introduction; 2. History of the French nuclear propulsion experimental reactors; 3. Needs of the naval propulsion and related objectives of the RES reactor; 4. RES architecture and main characteristics; 4.1. The pool module; 4.2. The reactor module; 4.3. The RES reactor, an innovative concept; 5. Realisation status; 6. Conclusion. To summarize, from the year 2009 the RES will be an efficient facility available for irradiation and qualification programs. Its large experimental capabilities will allow relevant fuel and core irradiations. This will give access to a real progress in the knowledge of fuel and core physics as well as in the related simulation tools. This reactor

    Highlights: • Given emissions restrictions, nuclear propulsion may be an alternative. • Plate and shell heat exchangers (PSHE) are a mature technology on market. • PSHE are compact and could be used as steam generators. • Preliminary calculations to obtain a PWR for a large container ship are performed. • Results suggest PSHE improve overall compactness and cost. - Abstract: The pressure on reduction of gas emissions is going to raise the price of fossil fuels and an alternative to fossil fuels is nuclear energy. Naval reactors have some differences from stationary PWR because they have limitations on volume and weight, requiring compact solutions. On the other hand, a source of problems in naval reactors across history is the steam generation function. In order to reduce nuclear containment footprint, it is desirable to employ integral designs, which, however, poses complications and design constraints for recirculation type steam generators, being interesting to employ once through steam generators, whose historic at Babcock and Wilcox is better than recirculation steam generators. Plate and shell heat exchangers are a mature technology made available by many suppliers which allows heat exchange at high temperature and pressure. This work investigates the feasibility of the use of an array of welded plate heat exchangers of a material approved by ASME for pressure barrier (Ti-3Al-2.5V) in a hypothetical naval reactor. It was found it is feasible from thermal-hydraulic point of view and presents advantages over other steam generator designs.

    Full Text Available Objective To investigate the epidemiological features and its potential related risk factors of adult rumination syndrome (ARS in Chinese naval servicemen, and to provide clinical basis for diagnosis and treatment of ARS. Methods A randomized cluster sampling method was used. Investigation and diagnosis were made according to the Rome Ⅲ Modular Questionnaire from November 2006 to April 2007, and 8600 cases were collected from naval forces. Results 7454 valid questionnaires were retrieved. The overall incidence of ARS was 2.32% (176/7574, male>female. The median age, age of conscription and length of military service were 23, 18 and 4 years respectively. The ARS was most common in unmarried people, who were 21-25 years old holding a high school diploma, with a 1-4 years military service. The incidence of ARS was different between groups with different gender, age, years of military service and marital status (P<0.05. No significant difference in the incidence between those with different education levels or blood types. The differences between individuals in ARS group and healthy controls were related to habit of overeating (P=0.0000, picky eating (P=0.0001, addiction to spicy food (P=0.0000, eating hard dry food (P=0.0001, and eating fruits (P=0.0188. Conclusion The overall incidence of ARS in naval force is 2.32%, and it is prevalent in young man. The body weight is an independent risk factor for ARS.

So, it was possible to afford a glimpse to a complex reality, in which gender relations and work relations present their own features, keeping, at the same time, standards of insertion and integration similar to those the non-military women engineers passed. The article begins indicating some aspects of the process of integration of women in the Brazilian Navy. Next, it is analyzed, from the point of view of the subjects, how they perceive their post, their image as women belonging to the body of official naval engineers, the work that they do as well as the gender relations in the military environment. The text finishes raising questions for future investigations.

    The relationship between energy generation availability and the safety of the nuclear installation which produces this energy assumes a very special characteristic when we are dealing with naval propulsion plants. This relationship has no parallel with commercial nuclear power plants. A ship at sea is in safety only if she could dispose quickly of the energy produced by your nuclear propulsion plant. If the nuclear steam production is not assured, specially due to safety reasons, the ship maneuverability, and so its own safety it is seriously affected. We could then perceive that safety of the nuclear installation is depends on safety of the ship, which depends by its side on the availability of nuclear power. This paper intends to present briefly the main aspects of this relation. (author)

  14. Examination of Sandwich Materials Using Air-Coupled Ultrasonics

    DEFF Research Database (Denmark)

    Borum, K.K.; Berggreen, Carl Christian

    2004-01-01

    The air-coupled ultrasonic techniques have been improved drastically in recent years. Better equipment has made this technique much more useful. This paper focuses on the examination of sandwich materials used in naval ships. It is more convenient to be able to make the measurements directly in...... atmospheric air instead of using immersion technique. The air-coupled techniques have been used in through-transmission mode using separate sender and receiver transducer. The frequency was either 50 kHz or 120 kHz. Laboratory tests on glass fibre/PVC foam core sandwich panels showed that debonds between core...... and skin laminate could be found by the air-coupled technique. It was therefore decided to use this technique in-situ during mechanical testing of sandwich panels. These tests were done in order to verify a developed FEM code using interfacial fracture mechanics and illustrated on a superstructure...

    2016-08-01

    Military physicians serving overseas in cross-cultural settings face the challenge of meeting patients' needs and adhering to their personal and professional ethics while abiding by military obligations and duties. Predeployment ethics training for Naval physicians continues to be received in many forms, if received at all, and has largely not addressed their specific roles as medical providers in the military. This study explores the perceived effectiveness of predeployment ethics training received by Naval physicians. Additionally, it considers the contribution of different types of ethics training, religious values, and the professional ethics on Naval physicians' perceived ability to effectively manage ethically challenging scenarios while on deployment. A total of 49 Naval physicians participated in an online survey. 16.3% reported not receiving any form of ethics training before deployment. Of those that reported receiving ethics training before deployment, 92.7% found the ethics training received was helpful in some way while on deployment. While a medical school course was most contributory overall to their ability to handle ethically difficult situations while on deployment (70.7%), what most Naval physicians felt would help them better handle these types of situations would be a mandatory military training/military course (63.2%) or personal mentorship (57.9%).

  16. Naval Petroleum and Oil Shale Reserves. Annual report of operations, Fiscal year 1993

    Energy Technology Data Exchange (ETDEWEB)

    1993-12-31

    During fiscal year 1993, the reserves generated $440 million in revenues, a $33 million decrease from the fiscal year 1992 revenues, primarily due to significant decreases in oil and natural gas prices. Total costs were $207 million, resulting in net cash flow of $233 million, compared with $273 million in fiscal year 1992. From 1976 through fiscal year 1993, the Naval Petroleum and Oil Shale Reserves generated $15.7 billion in revenues for the US Treasury, with expenses of $2.9 billion. The net revenues of $12.8 billion represent a return on costs of 441 percent. See figures 2, 3, and 4. In fiscal year 1993, production at the Naval Petroleum and Oil Shale Reserves at maximum efficient rates yielded 25 million barrels of crude oil, 123 billion cubic feet of natural gas, and 158 million gallons of natural gas liquids. The Naval Petroleum and Oil Shale Reserves has embarked on an effort to identify additional hydrocarbon resources on the reserves for future production. In 1993, in cooperation with the US Geological Survey, the Department initiated a project to assess the oil and gas potential of the program`s oil shale reserves, which remain largely unexplored. These reserves, which total a land area of more than 145,000 acres and are located in Colorado and Utah, are favorably situated in oil and gas producing regions and are likely to contain significant hydrocarbon deposits. Alternatively the producing assets may be sold or leased if that will produce the most value. This task will continue through the first quarter of fiscal year 1994.

  18. Exploring maintenance policy selection using the Analytic Hierarchy Process; An application for naval ships

    International Nuclear Information System (INIS)

    In this paper we investigate maintenance policy selection (MPS) through the use of the Analytic Hierarchy Process (AHP). A maintenance policy is a policy that dictates which parameter triggers a maintenance action. In practice, selecting the right maintenance policy appears to be a difficult decision. We investigate MPS for naval ships, but our results have wider applicability. For our study we cooperate with the owner and operator of the ships, as well as with a shipbuilder and an original equipment manufacturer of naval ships. We apply a structured five step approach to obtain the relevant criteria that may make one policy preferable over another. The criteria are drawn from both literature and a series of interviews at several navy related companies and are structured into a hierarchy of criteria usable with the AHP. Additionally, we organize three workshops at the three different companies to test the AHP-based MPS approach in practice. We conclude that the AHP is well suited for maintenance policy selection in this broad setting, and that it provides a structured and detailed approach for MPS. Adding to that, it facilitates discussions during and after the sessions, creating a better understanding of the policy selection process. - Highlights: • We use the Analytic Hierarchy Process (AHP) for maintenance policy selection (MPS). • Using both interviews and case studies from the literature, we construct a hierarchy. • In sessions at 3 companies, we find that 1 hierarchy can be used for multiple assets. • The AHP creates a better understanding of the maintenance policy selection process. • Our work is on naval ships, but our approach and findings have wider applicability

    Full Text Available Abstract Background The epidemic of HIV continues to grow in Nigeria. Personnel in the military are at increased risk of HIV infection. Although HIV-risk related sexual behavior of Nigerian police officers has been studied, little is known about the sexual behavior of their counterparts in the Navy. This study describes knowledge of AIDS, and HIV-risk sexual behavior of naval personnel in Lagos Nigeria. Methods Four hundred and eighty personnel of the Nigerian Navy completed a 70-item questionnaire in 2002. Group discussion and in-depth interviews of four key informants were also conducted to gain insights into the context of risky sexual behaviors and suggestions for feasible HIV primary prevention interventions. Results The mean age of the respondents was 34 years. Although the overall mean AIDS knowledge score was 7.1 of 10 points, 52.1% of respondents believed that a cure for AIDS was available in Nigeria and that one can get HIV by sharing personal items with an infected person (25.3%. The majority (88.1% had had lifetime multiple partners ranging from 1–40 with a mean of 5.1; 32.5% of male respondents had had sexual contact with a female sex worker, 19.9% did so during the six months preceding the survey. Forty-one percent of those with sexual contact with a female sex worker did not use a condom during the most recent sexual encounter with these women. Naval personnel who have been transferred abroad reported significantly more risky sexual behaviors than others. Group discussants and key informants believed that sex with multiple partners is a tradition that has persisted in the navy even in the era of AIDS because of the belief that AIDS affects only foreigners, that use of traditional medicine provides protection against HIV infection, and influence of alcohol. Conclusion Many naval personnel report participating in high-risk sexual behavior which may increase their risk of acquiring and spreading HIV. Naval personnel live and

    Much of the experiments that led to the development of World War I ship camouflage were conducted on an intuitive basis or based upon pseudo-scientific work. As a result of this rather empirical approach, possible effects of the naval camouflage schemes that were developed against the background of submarine warfare on the Atlantic still remain unclear. So-called dazzle paint schemes were conceived to break up target contours and disclose the ship’s number, direction, speed and distance—thus ...

    1994-01-01

    Naval Gunfire Support (NGFS) is a critical capability of the U.S. Navy, and is used to protect amphibious forces. Often, the execution of NGFS is time-critical. The accuracy of the shooting (called fall-of-shot) and the time it takes the gun crew to shoot the gun (called the gun cycle time), are two critical attributes of a mission. If the rounds land on or near the target, and if the gun crew can fire the gun quickly, the NGFS mission is most likely to be successful.

    Several U.S. Department of Defense base studies have been conducted to identify potential U.S. Department of Defense transportation systems that are strong candidates for introduction or expansion of plug-in electric vehicles (PEVs). Task 1 consisted of a survey of the non-tactical fleet of vehicles at NASWI to begin the review of vehicle mission assignments and types of vehicles in service. Task 2 selected vehicles for further monitoring and involved identifying daily operational characteristics of these select vehicles. Data logging of vehicle movements was initiated in order to characterize the vehicle’s mission. The Task 3 Vehicle Utilization report provided the results of the data analysis and observations related to the replacement of current vehicles with PEVs. This report provides an assessment of charging infrastructure required to support the suggested PEV replacements.

  11. Comparison of monitored natural attenuation with other alternatives for remediation of contaminated groundwater at Naval Air Station (NAS) Fallon, USA

    International Nuclear Information System (INIS)

    Monitored natural attenuation (MNA) and several other potential alternatives were evaluated for remediation of dissolved-phase groundwater contamination at Site 1, the former crash crew training area at NAS Fallon. The contaminants of concern at the site are petroleum hydrocarbon constituents and chlorinated ethenes. Remedial action objectives were developed using a conceptual model for the site, applicable regulatory action levels, site contaminants, and a point-of-compliance. A field evaluation of MNA was conducted at Site 1. Monitored natural attenuation was compared to other potential remedial alternatives for achieving the RAOs including: plume containment using pumping wells, interceptor drain, or slurry wall; and active restoration with enhanced in situ bioremediation, pump and treat using wells, or pump and treat using an interceptor drain. Alternatives were comparatively evaluated using three criteria, effectiveness, ability to implement and cost. The evaluation indicates that MNA is a viable and cost-effective remedial alternative for Site 1

    Current regulations of the Environmental Protection Agency (EPA) require that PCBs in concentrations greater than 500 ppM be disposed of in EPA-permitted incinerators. Four commercial incineration systems in the United States have EPA operating permits for receiving and disposing of concentrated PCBs, but none can accept PCBs contaminated with nuclear materials. The first section of this report presents an overview of an EPA-sponsored program for studying PCB destruction in the large-scale Los Alamos controlled-air incinerator. A second major FY 1983 program, sponsored by the Naval Weapons Support Center, Crane, Indiana, is designed to determine operating conditions that will destroy marker smoke compounds without also forming polycyclic aromatic hydrocarbons (PAHs), some of which are known or suspected to be carcinogenic. We discuss the results of preliminary trial burns in which various equipment and feed formulations were tested. We present qualitative analyses for PAHs in the incinerator offgas as a result of these tests.

    Full Text Available Naval surface ships should use thermally driven heating and cooling technologies to continue the Navy’s leadership role in protecting the marine environment. Steam ejector refrigeration (SER or steam ejector heat pump (SEHP systems are thermally driven heating and cooling technologies and seem to be a promising technology to reduce emissions for heating and cooling on board naval surface ships. In this study, design and thermodynamic analysis of a seawater cooled SER and SEHP as an HVAC system for a naval surface ship application are presented and compared with those of a current typical naval ship system case, an H2O-LiBr absorption heat pump and a vapour-compression heat pump. The off-design study estimated the coefficient of performances (COPs were 0.29–0.11 for the cooling mode and 1.29–1.11 for the heating mode, depending on the pressure of the exhaust gas boiler at off-design conditions. In the system operating at the exhaust gas boiler pressure of 0.2 MPa, the optimum area ratio obtained was 23.30.

  12. Final supplemental environmental impact statement/program environmental impact report for the sale of NPR-1. Sale of Naval Petroleum Reserve Number 1 (Elk Hills) Kern County, California

    International Nuclear Information System (INIS)

    The Proposed Action is the sale of all right, title and interest of the US in Naval Petroleum Reserve Number 1 (NPR-1) in accordance with the National Defense Authorization Act for Fiscal Year 1996 (Public Law 104-106). The Proposed Action is also DOE's Preferred Alternative. DOE has determined that the sale of NPR-1 as required by Public Law 104-106 constitutes a major Federal action which may have a significant impact upon the environment within the meaning of the National Environmental Policy Act of 1969 (NEPA) and Kern County has determined that the sale could have a significant effect on the environment under the California Environmental Quality Act of 1970 (CEQA). Significant impacts may occur because private-sector operation of the NPR-1 oil field could result in accelerated levels of development and different types of activities than under continued government ownership. This SEIS/PEIR assesses the potential environmental impacts from the Proposed Action, a No Action Alternative under which NPR-1 would continue to be operated by DOE, and an Alternative to the Proposed Action under which some form of government control would be maintained. This document assesses the environmental impacts on: geology and soils; hazardous materials and waste management; air; water; biology; cultural and historical resources; land use; noise socioeconomics; risk assessment; energy conservation; and environmental justice

    2008-04-01

    With large focal plane arrays now widely available, IR detectors have entered their third generation. Performances have increased dramatically with respect to second-generation, line array detectors, due to the longer integration times afforded. For surveillance systems such as InfraRed Search and Track (IRST), however, operational requirements generally impose a very large field of regard in relation to the instantaneous field of view. This characteristic which has traditionally been obtained through scanning motion for second generation line array detectors must now be rethought to obtain staring operation for 3rd generation FPA, lest motion blurring be incurred. This paper presents several approaches considered for naval surveillance systems at Sagem Defense Securite to tackle this challenge. Three techniques are presented and then compared: fully staring systems, step-and-stare systems, and finally a "modified" step-and-stare system.

    2016-04-01

    During the last years The San Fernando Naval Observatory (ROA) has deployed several GNSS stations in the South region of Spain (the seismic area in the Iberian Peninsula with the highest risk). These stations have been working uninterrupted (with some gap exceptions due to maintenance or equipment failures) for at least 6 years each, so a huge amount of data is available to process and analyze. The former is an important fact, since provided us long term time series in region near to the collision area between the African and The Euro-Asiatic plates. There are several faults near these plates where earthquakes are generated, so the study of the displacements of the region is very important. The aim of this work is to show the time series of the GNSS net of the ROA as well as its velocity.

    2000-07-01

    With the launching and commissioning of the Millennium ship during spring year 2000, technology and experience around podded propulsors were brought significantly forward. Millennium, a cruise liner built at Chantiers de l'Atlantique for Celebrity Cruises, is equipped with the most powerful podded propulsors ever built, the 19.5 MW Kamewal Alstom Mermaids, and is also the fastest pod propelled ship so far. This paper describes some experience from sea trials and ship operation. Results from full scale measurements and observations, ranging from cavitation performance to hydro acoustic noise, are discussed and compared to model scale results and predictions. The importance of model scale hydrodynamic testing, in combination with full scale observations, is emphasized as instrumental for a further development of podded propulsors towards naval applications.

  20. Evaluation of tandem gas metal arc welding for low distortion butt-welds in naval shipbuilding

    International Nuclear Information System (INIS)

    Tandem gas metal arc welding (T-GMAW) had been indentified as a welding process that is potentially capable of increasing productivity and minimizing distortion in the butt-welding of steel panels for the shipbuilding industry. In this study, the T-GMAW process has been used to butt-weld DH36 steel plate in order to determine its suitability as a replacement for submerged arc welding (SAW) or standard gas-metal-arc welding (GMAW) in naval shipbuilding applications. Experiments conducted show that the T-GMAW process is feasible and provides a significant improvement ove the SAW process in several respects, including higher travel speed, reduction in filler material, significantly lower post-weld distortion and residual stress, and a smaller heat affected zone (HAZ) with finer weld metal and HAZ microstructures. Furthermore, similar mechanical properties to those of SAW were obtained in the weld metal and HAZ.

    Full Text Available Fouling organisms collected from Indian Naval Ships dry-docked at Bombay during a period of two years (July 1956-June 1958 were studied in detail. Forty six of the forms collected have been identified. The most important groups of ship-fouling Organisms in Bombay waters are Barnacles, Hydroids, Polyzoans and Tube-worms. Eleven different Fouling Communities have been found to dominate the settlements on the hulls at different occasions. Definite zonations that could be observed were restriction of green algae to the boot-top area and mussels and oysters to the pipes and gratings. An attempt has been made to find the sequence of settlement of the different major fouling groups. Some general remarks on the observations have also been included.

  2. Automated radiological monitoring at a Russian Ministry of Defence Naval Site

    International Nuclear Information System (INIS)

    The Arctic Military Environmental Cooperation (AMEC) Program is a cooperative effort between the military establishments of the Kingdom of Norway, the Russian Federation, and the US. This paper discusses joint activities conducted over the past year among Norwegian, Russian, and US technical experts on a project to develop, demonstrate and implement automated radiological monitoring at Russian Navy facilities engaged in the dismantlement of nuclear-powered strategic ballistic missile launching submarines. Radiological monitoring is needed at these facilities to help protect workers engaged in the dismantlement program and the public living within the footprint of routine and accidental radiation exposure areas. By providing remote stand-alone monitoring, the Russian Navy will achieve added protection due to the defense-in-depth strategy afforded by local (at the site), regional (Kola) and national-level (Moscow) oversight. The system being implemented at the Polyaminsky Russian Naval Shipyard was developed from a working model tested at the Russian Institute for Nuclear Safety, Moscow, Russia. It includes Russian manufactured terrestrial and underwater gamma detectors, smart controllers for graded sampling, radio-modems for offsite transmission of the data, and a data fusion/display system: The data fusion/display system is derived from the Norwegian Picasso AMEC Environmental Monitoring software package. This computer package allows monitoring personnel to review the real-time and historical status of monitoring at specific sites and objects and to establish new monitoring protocols as required, for example, in an off-normal accident situation. Plans are being developed to implement the use of this system at most RF Naval sites handling spent nuclear fuel

    Several special status plant species occur or potentially occur at the Naval Petroleum Reserves in California (NPRC). Special status species are defined as those species that are either federally listed as endangered or threatened, or candidate taxa. Candidate species are classified as Category 1 or Category 2. Category 1 taxa are those species for which there is sufficient evidence to support listing, while Category 2 taxa are those species for which listing may possibly be appropriate, but for which sufficient data are lacking to warrant immediate listing. Determining the presence and distribution of these species on NPRC is necessary so that appropriate conservation or protection measures can be implemented. In the spring of 1988, a survey of Naval Petroleum Reserve No. 1 (NPR-1) was conducted to determine the occurrence of Hoover`s wooly-star (Eriastrum hooveri), Kern Mallow (Eremalche kemensis), San Joaquin wooly-threads (Lembertia congdonii), and California jewelflower (Caulanthus califonicus), all listed by the US Fish and Wildlife Service (FWS) as Category 2 species at that time. Of the four species, only Hoover`s wooly-star was found. It was concluded that Kern mallow and San Joaquin wooly-threads could potentially be found on NPR-1, but habitat for California jewelflower did not occur on NPR-1 and its occurrence was unlikely. As part of an ongoing effort to document the presence or absence of sensitive plant species on NPRC, surveys for species other than Hoover`s wooly-star were conducted in the spring of 1993. Abundant spring rains in 1993 created favorable growing conditions for annual forbs. Surveys in 1993 focused on potential habitat of several endangered and candidate species. The results of those surveys are presented in this report.

    1995-06-01

    This section of the 1994 Hanford Site Environmental Report summarizes the air surveillance and monitoring programs currently in operation at that Hanford Site. Atmospheric releases of pollutants from Hanford to the surrounding region are a potential source of human exposure. For that reason, both radioactive and nonradioactive materials in air are monitored at a number of locations. The influence of Hanford emissions on local radionuclide concentrations was evaluated by comparing concentrations measured at distant locations within the region to concentrations measured at the Site perimeter. This section discusses sample collection, analytical methods, and the results of the Hanford air surveillance program. A complete listing of all analytical results summarized in this section is reported separately by Bisping (1995).

  9. Effect of welding processes on mechanical and microstructural characteristics of high strength low alloy naval grade steel joints

    Directory of Open Access Journals (Sweden)

    S. Ragu Nathan

    2015-09-01

    Full Text Available Naval grade high strength low alloy (HSLA steels can be easily welded by all types of fusion welding processes. However, fusion welding of these steels leads to the problems such as cold cracking, residual stress, distortion and fatigue damage. These problems can be eliminated by solid state welding process such as friction stir welding (FSW. In this investigation, a comparative evaluation of mechanical (tensile, impact, hardness properties and microstructural features of shielded metal arc (SMA, gas metal arc (GMA and friction stir welded (FSW naval grade HSLA steel joints was carried out. It was found that the use of FSW process eliminated the problems related to fusion welding processes and also resulted in the superior mechanical properties compared to GMA and SMA welded joints.

    2012-02-01

    Full Text Available Cdr H. R. Gordon-Cumming has written that in the early days of the Second World War large drafts of RNVR (SA officers and ratings were taken by the few British Warships which called at Simonstown and Durban to make up their war complements and that later on 'Union nationals took part in nearly every major naval operation and also performed all manner of obscure duties, from minesweeping in the Faroe Islands to nautical surveying up the West River in China. Even the explosion of one of the atomic bombs in Japan was witnessed by a South African prisoner of war - a young RNVR seaman who had served in HMS Exter, sunk after the Battle of the Java Sea." This fascinating statement leaves the reader wanting to know the full story of our seconded naval personnel since it is clear that it is a particularly interesting and proud record of service.

  4. Naval History by Conspiracy Theory: The British Admiralty before the First World War and the Methodology of Revisionism

    OpenAIRE

    Seligmann, M

    2015-01-01

    Revisionist interpretations of British naval policy in the Fisher era claim that an elaborate smoke screen was created to hide the Royal Navy’s real policies; while documents showing the true goals were systematically destroyed. By asserting this, revisionists are able to dismiss those parts of the documentary record that contradict their theories, while simultaneously excusing the lack of evidence for their theories by claiming it has been destroyed. This article shows that this methodology ...

    Naval grade high strength low alloy (HSLA) steels can be easily welded by all types of fusion welding processes. However, fusion welding of these steels leads to the problems such as cold cracking, residual stress, distortion and fatigue damage. These problems can be eliminated by solid state welding process such as friction stir welding (FSW). In this investigation, a comparative evaluation of mechanical (tensile, impact, hardness) properties and microstructural features of shielded metal ar...

  10. Air pollution

    International Nuclear Information System (INIS)

    Australian cites experience a number of current and emerging air pollution problems. Concentrations of traditional primary pollutants such as CO, lead and dust have fallen in recent years as a consequence of air pollutant control measures, and the widespread introduction of lead-free petrol. However, recommended guidelines for ozone, the principal component of photochemical smog, are regularly exceeded in major capital cities in the summer months. In addition, it is predicted that extensive urban expansion will lead to much greater dependence on the motor vehicle as the primary means of transportation. Effects of air pollution are felt at a variety of scales. Traditionally, concerns about gaseous and particulate emissions from industrial and vehicular sources were focused on local impacts due to exposure to toxic species such as CO and lead. As noted above, concentrations of these pollutants have been reduced by a variety of control measures. Pollutants which have effects at a regional scale, such as photochemically-produced ozone, and acidic gases and particles have proved more difficult to reduce. In general, these pollutants arc not the result of direct emissions to atmosphere, but result from complex secondary processes driven by photochemical reactions of species such as NO2 and aldehydes. In addition, global effects of gaseous and particulate emissions to the atmosphere have received significant recent attention, concentrations of atmospheric CO2 with predicted impacts on global climate, and ozone depletion due to anthropogenic emissions of chlorine-containing chemicals are the two major examples. Combustion processes from petrol- and diesel-fuelled vehicles, make major contributions to air pollution, and the magnitude of this contribution is discussed in this article

  11. Final sitewide environmental assessment for continued development of Naval Petroleum Reserve No. 3 (NPR-3), Natrona County, Wyoming

    International Nuclear Information System (INIS)

    The Secretary of Energy is required by law to explore, prospect, conserve, develop, use, and operate the Naval Petroleum and Oil Shale Reserves. The Naval Petroleum Reserves Production Act of 1976 (Public Law 94-258), requires that the Naval Petroleum Reserves be produced at their maximum efficient rate (MER), consistent with sound engineering practices, for a period of six years. To fulfill this mission, DOE is proposing continued development activities which would include the drilling of approximately 250 oil production and injection (gas, water, and steam) wells, the construction of between 25 and 30 miles of associated gas, water, and steam pipelines, the installation of several production and support facilities, and the construction of between 15 and 20 miles of access roads. These drilling and construction estimates include any necessary activities related to the operation of the Rocky Mountain Oilfield Testing Center (RMOTC). The purpose of RMOTC will be to provide facilities and necessary support to government and private industry for testing and evaluating new oilfield and environmental technologies, and to transfer these results to the petroleum industry through seminars and publications. Continued development activities either have no potential to result in adverse environmental impacts or would only result in adverse impacts that could be readily mitigated. The small amounts of disturbed surface area will be reclaimed to its original natural state when production operations terminate. The preparation of an environmental impact statement is not required, and the DOE is issuing this Finding of No Significant Impact (FONSI). 73 refs

  12. An Overseas Naval Presence without Overseas Bases: China’s Counter-piracy Operation in the Gulf of Aden

    Directory of Open Access Journals (Sweden)

    Susanne Kamerling

    2011-01-01

    Full Text Available This article aims to assess how China is using its navy to secure its interests in the Gulf of Aden, and what this means for the European Union. The analysis of how China’s naval presence in the Gulf of Aden has evolved since early 2009 suggests that China’s increasing interests and involvement in Africa do not necessarily lead to the establishment of Chinese naval bases in or close to the continent. To supply its ships, the Chinese navy may well continue using the commercial-diplomatic model that China has been developing. This model is based on China’s close diplomatic relations with countries in the region and the extensive presence of Chinese companies to whom logistical services can be outsourced and who are under a greater degree of state influence than most Western multinationals. One of the consequences of this approach is that although China may not establish overseas military bases, it may be able to keep expanding its naval presence in or around Africa.

    The Naval Petroleum and Oil Shale Reserves (NPOSR) produces crude oil and associated hydrocarbons from the Naval Petroleum Reserve No. 1 (NPR-1) in a manner to achieve the greatest value and benefits to the US taxpayer. As required by the 1996 National Defense Authorization Act, the Department of Energy offered NPR-1 for sale during FY 1997. DOE structured the sale so as to offer two types of ownership segments: one operatorship segment, consisting of 74% of the US interest in NPR-1, and 13 nonoperating segments, each consisting of 2% of the US interest. Potential purchasers could bid on one, some, or all of the segments. If a single purchaser wanted to buy all of the Government`s interest, then its bid would have to exceed the total of the highest bids for all of the individual segments. Bids were due October 1, 1997, at which time DOE received 22 bids from 15 parties acting alone or in concert. The report and management letter present the results of the independent certified public accountants` audits of the Department of Energy`s Naval Petroleum Reserve Number 1 (NPR-1) financial statements as of, and for the years ended, September 30, 1997 and 1996.

  17. Department of the Navy final environmental impact statement for a container system for the management of naval spent nuclear fuel

    International Nuclear Information System (INIS)

    This Final Environmental Impact Statement (EIS) addresses six general alternative systems for the loading, storage, transport, and possible disposal of naval spent nuclear fuel following examination. This EIS describes environmental impacts of (1) producing and implementing the container systems (including those impacts resulting from the addition of the capability to load the containers covered in this EIS in dry fuel handling facilities at Idaho National Engineering Laboratory (INEL)); (2) loading of naval spent nuclear fuel at the Expended Core Facility or at the Idaho Chemical Processing Plant with subsequent storage at INEL; (3) construction of a storage facility (such as a paved area) at alternative locations at INEL; and (4) loading of containers and their shipment to a geologic repository or to a centralized interim storage site outside the State of Idaho once one becomes available. As indicated in the EIS, the systems and facilities might also be used for handling low-level radiological waste categorized as special case waste. The Navy's preferred alternative for a container system for the management of naval spent fuel is a dual-purpose canister system. The primary benefits of a dual-purpose canister system are efficiencies in container manufacturing and fuel reloading operations, and potential reductions in radiation exposure

  18. Causal reasoning and models of cognitive tasks for naval nuclear power plant operators

    International Nuclear Information System (INIS)

    In complex industrial process control, causal reasoning appears as a major component in operators' cognitive tasks. It is tightly linked to diagnosis, prediction of normal and failure states, and explanation. This work provides a detailed review of literature in causal reasoning. A synthesis is proposed as a model of causal reasoning in process control. This model integrates distinct approaches in Cognitive Science: especially qualitative physics, Bayesian networks, knowledge-based systems, and cognitive psychology. Our model defines a framework for the analysis of causal human errors in simulated naval nuclear power plant fault management. Through the methodological framework of critical incident analysis we define a classification of errors and difficulties linked to causal reasoning. This classification is based on shallow characteristics of causal reasoning. As an origin of these errors, more elementary component activities in causal reasoning are identified. The applications cover the field of functional specification for man-machine interfaces, operators support systems design as well as nuclear safety. In addition of this study, we integrate the model of causal reasoning in a model of cognitive task in process control. (authors). 106 refs., 49 figs., 8 tabs

    In FY96, Enterprise Advisory Services, Inc. (EASI) continued to support efforts to protect endangered species and cultural resources at the Naval Petroleum Reserves in California (NPRC). These efforts are conducted to ensure NPRC compliance with regulations regarding the protection of listed species and cultural resources on federal properties. Population monitoring activities were conducted for San Joaquin kit foxes, giant kangaroo rats, blunt-nosed leopard lizards, and Hoover`s wooly-star. Kit fox abundance and distribution was assessed by live-trapping over a 329-km{sup 2} area. Kit fox reproduction and mortality were assessed by radiocollaring and monitoring 22 adults and two pups. Reproductive success and litter size were determined through live-trapping and den observations. Rates and sources of kit fox mortality were assessed by recovering dead radiocollared kit foxes and conducting necropsies to determine cause of death. Abundance of coyotes and bobcats, which compete with kit foxes, was determined by conducting scent station surveys. Kit fox diet was assessed through analysis of fecal samples collected from live-trapped foxes. Abundance of potential prey for kit foxes was determined by conducting transect surveys for lagornorphs and live-trapping small mammals.

  20. Case-control study of leukemia at a naval nuclear shipyard

    International Nuclear Information System (INIS)

    A matched case-control study was conducted of 53 leukemia deaths and of 212 controls within a previously studied cohort of 24,545 on-shore workers employed between January 1, 1952 and August 15, 1977 at the Portsmouth (New Hampshire) Naval Shipyard. The study sought to ascertain a priori whether there was an association between leukemia deaths and occupational exposure to either ionizing radiation or organic solvents. To obtain information on individual exposures, radiation dose histories and detailed work histories by job and shop were evaluated for each subject. No statistically significant associations were found either between ionizing radiation or presumed solvent exposure and myelogenous or lymphatic leukemia. However, when specific job categories and shops were examined without benefit of a priori hypotheses, two occupations, electrician and welder, were found to be associated with leukemia. For electricians, the Mantel-Haenszel odds ratio (ORMH) was significantly elevated for all leukemias (ORMH = 3.00, 95% confidence interval (CI) = 1.29-6.98), particularly for lymphatic leukemia (ORMH = 6.00, 95% CI = 1.47-24.45). For welders, the odds ratio was not significantly elevated for all leukemias (ORMH = 2.25, 95% CI = 0.92-5.53), but was significantly elevated for myeloid leukemia (ORMH = 3.83, 95% CI = 1.28-11.46). These findings persisted when potential confounders were adjusted by means of a conditional logistic regression model

  1. Optimizing the Ar-Xe infrared laser on the Naval Research Laboratory's Electra generator

    International Nuclear Information System (INIS)

    The Ar-Xe infrared laser has been investigated in several series of experiments carried out on the Naval Research Laboratory's Electra generator. Our primary goals were to optimize the efficiency of the laser (within Electra's capabilities) and to gain understanding of the main physical processes underlying the laser's output as a function of controllable parameters such as Xe fraction, power deposition, and gas pressure. We find that the intrinsic efficiency maximizes at ∼3% at a total pressure of 2.5 atm, Xe fraction of 1%, and electron beam power deposition density of 50-100 kW cm-3. We deployed an interferometer to measure the electron density during lasing; the ionization fractions of 10-5-10-4 that it detected well exceed previous theoretical estimates. Some trends in the data as a function of beam power and xenon fraction are not fully understood. The as-yet incomplete picture of Ar-Xe laser physics is likely traceable in large part to significant uncertainties still present in many important rates influencing the atomic and molecular kinetics

  2. Advancing science diplomacy: Indonesia and the US Naval Medical Research Unit.

    2014-12-01

    Science diplomacy supposedly builds international cooperation through scientific and technical exchange. In practice, however, there are important but often overlooked instances where it might create conflict instead--as with accusations of espionage surrounding the US Naval Medical Research Unit 2 (NAMRU-2) in Indonesia. Did American science diplomacy backfire in Indonesia and, if so, why? Most literature fails to anticipate this possibility, let alone explain it, since science diplomacy is rarely subject to critical analysis. Rather than shun politics or, similarly, simply blame the demise of NAMRU-2 on the military or avian influenza, I consider both the successes and failures of this research unit in the context of Indonesia's transition to democracy and America's legacy from the Cold War. Based on this history, I propose that the effects of science diplomacy depend on strategic communication and exchange, as well as elite influence and material incentives. Therefore, by challenging the conventional wisdom about science diplomacy, NAMRU-2 can help advance the theory and practice of this potentially useful tool of statecraft. PMID:25608440

    1989-01-01

    This summary for Naval Petroleum Reserves in California (NPRC) is divided into NPR-1 and NPR-2. Monitoring efforts at NPR-1 include handling and disposal of oilfield wastes; environmental preactivity surveys for the protection of endangered species and archaeological resources; inspections of topsoil stockpiling; monitoring of revegetated sites; surveillance of production facilities for hydrocarbons and oxides of nitrogen (NO{sub x}) emissions; monitoring of oil spill prevention and cleanup; and monitoring of wastewater injection. No major compliance issues existed for NPR-1 during 1989. Oil spills are recorded, reviewed for corrective action, and reported. Environmental preactivity surveys for proposed projects which may disturb or contaminate the land are conducted to prevent damage to the federally protected San Joaquin kit fox, blunt-nosed leopard lizard, Tipton kangaroo rat and the giant kangaroo rat. Projects are adjusted or relocated as necessary to avoid impact to dens, burrows, or flat-bottomed drainages. A major revegetation program was accomplished in 1989 for erosion control enhancement of endangered species habitat. The main compliance issue on NPR-2 was oil and produced water discharges into drainages by lessees. An additional compliance issue on NPR-2 is surface refuse from past oilfield operations. 17 refs.

    2011-06-01

    The Anti-ship Missile (ASM) threat to be faced by ships will become more diverse and difficult. Intelligence, rules of engagement constraints, fast reaction-time for effective softkill solution require specific tools to design Electronic Warfare (EW) systems and to integrate it onboard ship. SAGEM Company provides decoy launcher system [1] and its associated Naval Electronic Warfare Simulation tool (NEWS) to permit softkill effectiveness analysis for anti-ship missile defence. NEWS tool generates virtual environment for missile-ship engagement and counter-measure simulator over a wide spectrum: RF, IR, EO. It integrates EW Command & Control (EWC2) process which is implemented in decoy launcher system and performs Monte-Carlo batch processing to evaluate softkill effectiveness in different engagement situations. NEWS is designed to allow immediate EWC2 process integration from simulation to real decoy launcher system. By design, it allows the final operator to be able to program, test and integrate its own EWC2 module and EW library onboard, so intelligence of each user is protected and evolution of threat can be taken into account through EW library update. The objectives of NEWS tool are also to define a methodology for trial definition and trial data reduction. Growth potential would permit to design new concept for EWC2 programmability and real time effectiveness estimation in EW system. This tool can also be used for operator training purpose. This paper presents the architecture design, the softkill programmability facility concept and the flexibility for onboard integration on ship. The concept of this operationally focused simulation, which is to use only one tool for design, development, trial validation and operational use, will be demonstrated.

  12. Use of microbes for paraffin cleanup at Naval Petroleum Reserve No. 3

    Energy Technology Data Exchange (ETDEWEB)

    Giangiacomo, L.; Khatib, A.

    1995-12-31

    Naval Petroleum Reserve No. 3 (NPR-3), also known as Teapot Dome, is a government-owned oil field in Natrona County, Wyoming. It is an asymmetrical anticline located on the western edge of the Powder River Basin, just south of the Salt Creek Anticline. Production started in 1922, and today the field is a marginally economic stripper field with average production of less than 3 BOPD (0.5 m{sup 3}/D) per well. Total field production is about 1,800 BOPD (286 m{sup 3}/D). The Second Wall Creek Formation was waterflooded from 1979 until June 1992 with poor results due to the extensive natural fracture system in this sandstone unit. Since water injection ceased, reservoir pressure has declined to very low levels. Liquids extraction and reinjection of the gas produced from high-GOR wells along the gas-oil contact continues, but the average gas cap pressure has fallen to approximately 150 psi (1.03 MPa) from an original pressure of 1,120 psi (7.72 MPa). Since the oil is highly paraffinic, wax deposition in the hydraulic fractures and the perforations has become a serious production problem. Microbial treatment was considered as a possible low-cost solution. Four wells were selected in the Second Wall Creek Reservoir with severe paraffin problems and production rates high enough to economically justify the treatment. Problems were experienced with the production of thick oil after approximately three months. This was interpreted to be a result of previously immobile paraffin being cleaned up. A slight decrease in the decline rate was seen in the wells, although some external factors cloud the interpretation. Microbial treatments were discontinued because of marginal economics. Three of the four wells produced additional oil and had a positive incremental cash flow. Oil viscosity tests did indicate that some positive microbial thinning was occurring, and changes to the treatment procedure may potentially yield more economic results in the future.

    The aim of the present study was to investigate how night duties can affect the circadian rhythms of military personnel working onboard a naval ship. Twenty individuals on a regular day-work schedule from 9:00 a.m. to 6:00 p.m. (serving as controls) and 40 individuals on night-shift duties participated in the study. Salivary melatonin and cortisol profiles were established within two 24-hour periods from 2-hour saliva samplings. Under the condition of abrupt shift in work/rest schedule, the majority of the navy officers (52%) retained their normal melatonin profiles. Twelve percent displayed a right phase shift in melatonin rhythm after night work. Nineteen percent exhibited distortions in the form of abnormal peaks or troughs, and 17% showed signs of disrupted rhythm in the form of low daytime levels of melatonin throughout the sampling period. No consistent relationship was found between the melatonin changes and various work stations of the ship. Prominent changes in the cortisol profile included unexpected peaks or troughs that may be related to the conditions that individuals were exposed to, i.e., high noise level in the engine room, as well as to performing intense tracking operations. The findings of this study (1) show the possible detrimental effects of shift duties on circadian rhythms, (2) highlight a wide interindividual variation in the manner in which the circadian systems respond to an abrupt phase shift in work/rest schedules, and (3) form the basis for further investigations into effective strategies to help military personnel cope with shift work, thereby maintaining health and high working standards while on duty.

  14. Endangered species and cultural resources program, Naval Petroleum Reserves in California: Annual report FY95

    International Nuclear Information System (INIS)

    In FY95, EG and G Energy Measurements, Inc. (EG and G/EM) continued to support efforts to protect endangered species and cultural resources at the Naval Petroleum Reserves in California (NPRC). These efforts are conducted to ensure NPRC compliance with regulations regarding the protection of listed species and cultural resources on Federal properties. Population monitoring activities are conducted annually for San Joaquin kit foxes, giant kangaroo rats, blunt-nosed leopard lizards, and Hoover's wooly-star. To mitigate impacts of oil field activities on listed species, 674 preactivity surveys covering approximately 211 hectares (521 acres) were conducted in FY95. EG and G/EM also assisted with mitigating effects from third-party projects, primarily by conducting biological and cultural resource consultations with regulatory agencies. EG and G/EM has conducted an applied habitat reclamation program at NPRC since 1985. In FY95, an evaluation of revegetation rates on reclaimed and non-reclaimed disturbed lands was completed, and the results will be used to direct future habitat reclamation efforts at NPRC. In FY95, reclamation success was monitored on 50 sites reclaimed in 1985. An investigation of factors influencing the distribution and abundance of kit foxes at NPRC was initiated in FY94. Factors being examined include habitat disturbance, topography, grazing, coyote abundance, lagomorph abundance, and shrub density. This investigation continued in FY95 and a manuscript on this topic will be completed in FY96. Also, Eg and G/EM completed collection of field data to evaluate the effects of a well blow-out on plant and animal populations. A final report will be prepared in FY96. Finally, EG and G/EM completed a life table analysis on San Joaquin kit foxes at NPRC

    Habitats in and around Naval Petroleum Reserve No. 1 (NPR-1) support populations of various vertebrates and plants, including a number of threatened and endangered species. Adequate conservation of habitats and species, particularly protected species, can be facilitated through development and implementation of management plans. This document provides a comprehensive plan for the conservation of protected species on NPR-1, through compliance with terms and conditions expressed in Biological Opinions rendered by the U.S. Fish and Wildlife Service for NPR-1 activities. Six conservation strategies by which threatened and endangered species have been, and will be, protected are described: population monitoring, mitigation strategies, special studies, operating guidelines and policies, information transfer and outreach, and the endangered species conservation area. Population monitoring programs are essential for determining population densities and for assessing the effects of oil field developments and environmental factors on protected species. Mitigation strategies (preactivity surveys and habitat reclamation) are employed to minimize the loss of important habitats components and to restore previously disturbed lands to conditions more suitable for species` use. A number of special studies were undertaken between 1985 and 1995 to investigate the effectiveness of a variety of population and habitat management techniques with the goal of increasing the density of protected species. Operating guidelines and policies governing routine oil field activities continue to be implemented to minimize the potential for the incidental take of protected species and minimize damage to wildlife habitats. Information transfer and outreach activities are important means by which technical and nontechnical information concerning protected species conservation on NPR-1 is shared with both the scientific and non-scientific public.

    The Naval Observatory Vector Astrometry Software (NOVAS) is a source - code library that provides common astrometric quantities and transformations to high precision. The library can supply, in one or two subroutine or function calls, the instantaneous celestial position of any star or planet in a variety of coordinate systems. NOVAS also provides access to all of the building blocks that go into such computations. NOVAS is used for a wide variety of applications, including the U.S. portions of The Astronomical Almanac and a number of telescope control systems. NOVAS uses IAU recommended models for Earth orientation, including the IAU 2006 precession theory, the IAU 2000A and 2000B nutation series, and diurnal rotation based on the celestial and terrestrial intermediate origins. Equinox - based quantities, such as sidereal time, are also supported. NOVAS Earth orientation calculations match those from SOFA at the sub - microarcsecond level for comparable transformations. NOVAS algorithms for aberration an d gravitational light deflection are equivalent, at the microarcsecond level, to those inherent in the current consensus VLBI delay algorithm. NOVAS can be easily connected to the JPL planetary/lunar ephemerides (e.g., DE405), and connections to IMCCE and IAA planetary ephemerides are planned. NOVAS Version 3.1 introduces a Python edition alongside the Fortran and C editions. The Python edition uses the computational code from the C edition and currently mimics the function calls of the C edition. Future versions will expand the functionality of the Python edition to exploit the object - oriented features of Python. In the Version 3.1 C edition, the ephemeris - access functions have been revised for use on 64 - bit systems and for improved performance in general. NOVAS source code, auxiliary files, and documentation are available from the USNO website (http://aa.usno.navy.mil/software/novas/novas_info.php).

    Sensitivity to religious calendars is increasingly expected when planning activities. Consequently, the U.S. Naval Observatory (USNO) has redesigned its on-line calendar resources to allow the computation of select religious dates for specific years via an application programming interface (API). This flexible interface returns dates in JavaScript Object Notation (JSON) that can be incorporated into third-party websites or applications. Currently, the services compute Christian, Islamic, and Jewish events.The “Dates of Ash Wednesday and Easter” service (http://aa.usno.navy.mil/data/docs/easter.php) returns the dates of these two events for years after 1582 C.E. (1582 A.D.) The method of the western Christian churches is used to determined when Easter, a moveable feast, occurs.The “Dates of Islamic New Year and Ramadan” service (http://aa.usno.navy.mil/data/docs/islamic.php) returns the approximate Gregorian dates of these two events for years after 1582 C.E. (990 A.H.) and Julian dates are computed for the years 622–1582 C.E. (1–990 A.H.). The appropriate year in the Islamic calendar (anno Hegira) is also provided. Each event begins at 6 P.M. or sunset on the preceding day. These events are computed using a tabular calendar for planning purposes; in practice, the actual event is determined by observation of the appropriate new Moon.The “First Day of Passover” service (http://aa.usno.navy.mil/data/docs/passover.php) returns the Gregorian date corresponding to Nisan 15 for years after 1582 C.E. (5342 A.M.) and Julian dates are computed for the years 360–1582 C.E. (4120–5342 A.M.). The appropriate year in the Jewish calendar (anno Mundi) is also provided. Passover begins at 6 P.M. or sunset on the preceding day.On-line documentation for using the API-enabled calendar computers, including sample calls, is available (http://aa.usno.navy.mil/data/docs/api.php).

    These remotely sensed, geographically referenced color-infrared (CIR) imagery and elevation measurements of lidar-derived bare-earth (BE) topography, first-surface (FS) topography, and canopy-height (CH) datasets were produced collaboratively by the U.S. Geological Survey (USGS), St. Petersburg Science Center, St. Petersburg, FL; the National Park Service (NPS), Gulf Coast Network, Lafayette, LA; and the National Aeronautics and Space Administration (NASA), Wallops Flight Facility, VA. This project provides highly detailed and accurate datasets of the Naval Live Oaks Area in Florida's Gulf Islands National Seashore, acquired June 30, 2007. The datasets are made available for use as a management tool to research scientists and natural-resource managers. An innovative airborne lidar instrument originally developed at the NASA Wallops Flight Facility, and known as the Experimental Advanced Airborne Research Lidar (EAARL), was used during data acquisition. The EAARL system is a raster-scanning, waveform-resolving, green-wavelength (532-nanometer) lidar designed to map near-shore bathymetry, topography, and vegetation structure simultaneously. The EAARL sensor suite includes the raster-scanning, water-penetrating full-waveform adaptive lidar, a down-looking red-green-blue (RGB) digital camera, a high-resolution multispectral CIR camera, two precision dual-frequency kinematic carrier-phase GPS receivers, and an integrated miniature digital inertial measurement unit, which provide for sub-meter georeferencing of each laser sample. The nominal EAARL platform is a twin-engine Cessna 310 aircraft, but the instrument may be deployed on a range of light aircraft. A single pilot, a lidar operator, and a data analyst constitute the crew for most survey operations. This sensor has the potential to make significant contributions in measuring sub-aerial and submarine coastal topography within cross-environmental surveys. Elevation measurements were collected over the survey area

  4. Design of a one-chip board microcontrol unit for active vibration control of a naval ship mounting system

    International Nuclear Information System (INIS)

    This work presents an experimental implementation of a user-tunable one-chip board microcontrol unit which is specifically designed for vibration control of the active mounting system for naval ships. The proposed mounting system consists of four active mounts supporting vibration-sensitive equipment. Each active mount constitutes a rubber element, an inertial mass and the piezostack actuator. It is designed for particular applications that require effective isolation performance against wide frequency ranges, such as naval ship equipment. After describing the configuration of the active mount, dynamic characteristics of the rubber element and the piezostack actuator are experimentally identified. Accordingly, the proposed mounting system is constructed and the governing equations of motion are formulated. In order to attenuate the unwanted vibrations transferred from the upper mass, a feedforward controller with fast Fourier algorithm is designed and experimentally realized using the one-chip microcontrol board which is specially made for this practical application. In order to evaluate the performance of the one-chip microcontrol unit, vibration control results of the proposed active mounting system are presented in the frequency domain. (technical note)

    In the effort to predict dust storms and their effects on local, regional and global scales an often cited uncertainty is the precise location of dust sources. Many approaches have been used to identify major dust source regions in East Asia. These approaches include analysis of station data for frequency of dust storms, drifting dust, dusty day, wind speed, and PM10 total suspended particulates. Some approaches emphasize the location of land surface type (Gobi, sandy desert, and loess) and geomorphological setting/features (basins, plateaus, alluvial fans, dry rivers, or oases). Other approaches use remote sensing to locate areas of high dust activity using the Total Ozone Mapping Spectrometer Aerosol Index (TOMS AI) data, to correlate Normalized Difference Vegetation Index (NDVI) vegetation cover with dust storm frequency, or to track dust storm event origination by analyzing Moderate Resolution Imaging Spectroradiometer (MODIS) images. It is also customary for researchers to combine two or more of these approaches to identify dust source regions. In this paper we use a novel approach to locate dust sources in East Asia. Utilizing the Naval Research Laboratory's satellite derived 1-km Dust Enhancement Product (DEP) imagery we can readily distinguish elevated dust over land from other components of the scene and individual dust plumes are readily seen. The high resolution of the DEP allows the many small, eroding point sources (measuring 1-10s km across) that form individual plumes to be located. Five years (2007 - 2011) of East Asia DEP imagery have been analyzed. Dust source frequency plots will be shown highlighting the most active dust source areas in East Asia. Our results show the most active point sources are located along the slopes and around the rim of large basins. Within basins, on plateaus and in valleys point sources are concentrated in smaller depressions relative to the surrounding topography. Point sources are also associated with the action of

    Full Text Available Four high-strength low-alloy (HSLA steels with varying chemical compositions were forgedin two different temperature ranges followed by cooling in various media. Microstructures andmechanical properties of the steels were evaluated. The microstructures obtained in water–quenchedlow-carbon HSLA steels were lath martensite packet within the pancaked grains. On air or sandcooling predominantly bainitic ferrite or granular bainite structure forms. The strength propertiesof these steels decreased with decrease in cooling rate and is accompanied by an increase inelongation and impact toughness values. The ductile-to-brittle transition temperature of HSLA-100grade steel was found to be – 40 oC. The impact fracture surface of air cooled HSLA-100 steel showedductile failure with formation of dimples at 20 oC and at – 20 oC. The fracture mode changed to brittlefailure with formation of cleavage and river pattern at – 40 oC and at – 60 oC. The microstructuresof the ultra-low carbon HSLA steel show lath ferrite or granular ferrite in water-quenched condition.With slower cooling rate, the volume fraction of lath ferrite decreased with an increase in formationof polygonal ferrite. The maximum strength value obtained in air-cooled condition is achieved dueto precipitation of fine microalloying carbides and carbonitrides. Slower cooling rate increases thevolume fraction of polygonal ferrite which increases the toughness value.

    Full Text Available Multiple attributes decision making (MADM method is an important measure for system integration. Robustness analysis on MADM is a hotspot in these years which wins academe’s great attention, and is supposed to be an effective way when countering imperfect information. Setting parameters in ELECTRE-III’s is a vital and difficult step. In this paper, a method of inferring ELECTRE-III’s parameters with fuzzy information based on robustness analysis is presented. First, ELECTRE-III is transformed into a continuous smooth function of each parameter vector. Then, robustness analysis structure and a parameters inferring algorithm are provided by maximizing robustness margin based on mathematics programming. Moreover, how to resolve the programming problem is also discussed. At last, a illustrative example of Naval Gun Weapon System Integration is put forward.

    Lean Six Sigma (LSS) is a process improvement methodology developed in the manufacturing industry to increase process efficiency while maintaining product quality. The efficacy of LSS application to the health care setting has not been adequately studied. This article presents a quality improvement project at the U.S. Naval Academy that uses LSS to improve the mass immunizations process for Midshipmen during in-processing. The process was standardized to give all vaccinations at one station instead of giving a different vaccination at each station. After project implementation, the average immunizations lead time decreased by 79% and staffing decreased by 10%. The process was shown to be in control with a capability index of 1.18 and performance index of 1.10, resulting in a defect rate of 0.04%. This project demonstrates that the LSS methodology can be applied successfully to the health care setting to make sustainable process improvements if used correctly and completely. PMID:27244070

    The U.S. Geological Survey and the Naval Facilities Engineering Command Southeast investigated natural and engineered remediation of chlorinated volatile organic compound (VOC) groundwater contamination at Solid Waste Management Unit 12 at the Naval Weapons Station Charleston, North Charleston, South Carolina, beginning in 2000. The primary contaminants of interest in the study are tetrachloroethene, 1,1,1-trichloroethane, trichloroethene, cis-1,2-dichloroethene, vinyl chloride, 1,1-dichloroethane, and 1,1-dichloroethene. Engineered remediation aspects at the site consist of a zero-valent-iron permeable reactive barrier (PRB) installed in December 2002 intercepting the contamination plume and a phytoremediation test stand of loblolly pine trees planted in the source area in May 2003. The U.S. Geological Survey planted an additional phytoremediation test stand of loblolly pine trees on the upgradient side of the southern end of the PRB in February 2008. At least once during the summer, however, the trees were inadvertently mowed during lawn cutting activity. The PRB along the main axis of the contaminant plume appears to be actively removing contamination. In contrast to the central area of the PRB, the data from the southern end of the PRB indicate that contaminants are moving around the PRB. Concentrations in wells upgradient from the PRB showed a general decrease in VOC concentrations. VOC concentrations in some wells in the forest downgradient from the PRB showed a sharp increase in 2005, followed by a decrease in 2006. Farther downgradient in the forest, the VOC concentrations began to increase in 2007 and continued to increase into 2008. The VOC-concentration changes in groundwater beneath the forest appear to indicate movement of a groundwater-contaminant pulse through the forest. It also is possible that the data may represent lateral shifting of the plume in response to changes in groundwater-flow direction.

  9. An Atom Probe Tomographic Investigation of High-Strength, High-Toughness Precipitation Strengthened Steels for Naval Applications

    Science.gov (United States)

    Hunter, Allen H.

    Novel high-strength high-toughness alloys strengthened by precipitation are investigated for use in naval applications. The mechanical properties of an experimental steel alloy, NUCu-140, are evaluated and are not suitable for the naval requirements due to poor impact toughness at -40°C. An investigation is conducted to determine optimum processing conditions to restore toughness. A detailed aging study is conducted at 450, 500, and 550°C to determine the evolution of the microstructure and mechanical properties. A combination of transmission electron microscopy (TEM), synchrotron X-ray Diffraction (XRD), and Local electrode atom probe (LEAP) tomography are used to measure the evolution of the Cu precipitates, austenite, NbC, and cementite phases during aging. The evolution of the Cu precipitates significantly affects the yield strength of the steel, but low temperature toughness is controlled by the cementite precipitates. Extended aging is effective at improving the impact toughness but the yield strength is also decreased due to coarsening of the Cu precipitates. To provide a foundation for successful welding of NUCu-140 steel, an investigation of the effects of gas metal arc welding (GMAW) are performed. The microstructures in the base metal (BM), heat affected zone (HAZ), and fusion zone (FZ) of a GMAW sample are analyzed to determine the effects of the welding thermal cycle. Weld simulation samples with known thermal histories are prepared and analyzed by XRD and LEAP tomography. A significant loss in microhardness is observed as a result of dissolution of the Cu precipitates after the weld thermal cycle. The cooling time is too rapid to allow significant precipitation of Cu. In addition to the NUCu-140 alloy, a production HSLA-115 steel alloy is investigated using TEM, XRD, and LEAP tomography. The strength of the HSLA-115 is found to be derived primarily from Cu precipitates. The volume fractions of cementite, austenite, and NbC are measured by XRD

    Full Text Available The continuous damage of the used fuel quality, of its dispersion due to the increasingviscosity, make necessary the volume expansion and the rise of the e electric spark power used at ignition. Asimilar situation appears to the transition of the generator operation from the marine Diesel heavy fuel to theresidues of water-fuel mixture. So, it feels like using an ignition system with high specific energy and power ableto perform the starting and burning of the fuels mentioned above. Such a system is that which uses a lowtemperature plasma jet. Its use involves obtaining a high temperature area round about the jet, with a highdischarge power, extending the possibility of obtaining a constant burning of different concentration (densitymixtures. Besides the action of the temperature of the air-fuel mixture, the plasma jet raises the rate of oxidationreaction as a result of appearance of lot number of active centers such as loaded molecules, atoms, ions, freeradicals

  17. Nitrogen Species in Soil, Sediment, and Ground Water at a Former Sewage-Treatment Wastewater Lagoon: Naval Air Station Whidbey Island, Island County, Washington

    Science.gov (United States)

    Cox, S.E.; Dinicola, R.S.; Huffman, R.L.

    2007-01-01

    The potential for contamination of ground water from remnant sewage sludge in re-graded sediments of a deconstructed sewage-treatment lagoon was evaluated. Ground-water levels were measured in temporary drive-point wells, and ground-water samples were collected and analyzed for nutrients and other water-quality characteristics. Composite soil and sediment samples were collected and analyzed for organic carbon and nitrogen species. Multiple lines of evidence, including lack of appreciable organic matter in sediments of the former lagoon, agronomic analysis of nitrogen, the sequestration of nitrogen in the developing soils at the former lagoon, and likely occurrence of peat deposits within the aquifer material, suggest that the potential for substantial additions of nitrogen to ground water beneath the former sewage lagoon resulting from remnant sewage sludge not removed from the former lagoon are small. Concentrations of nitrogen species measured in ground-water samples were small and did not exceed the established U.S. Environmental Protection Agency's maximum contaminant levels for nitrate (10 milligrams per liter). Concentrations of nitrate in ground-water samples were less than the laboratory reporting limit of 0.06 milligram per liter. Seventy to 90 percent of the total nitrogen present in ground water was in the ammonia form with a maximum concentration of 7.67 milligrams per liter. Concentrations of total nitrogen in ground water beneath the site, which is the sum of all forms of nitrogen including nitrate, nitrite, ammonia, and organic nitrogen, ranged from 1.15 to 8.44 milligrams per liter. Thus, even if all forms of nitrogen measured in ground water were converted to nitrate, the combined mass would be less than the maximum contaminant level. Oxidation-reduction conditions in ground water beneath the former sewage lagoon were reducing. Given the abundant supply of ambient organic carbon in the subsurface and in ground water at the former lagoon, any nitrate that may leach from residual sludge and be transported to ground water with recharge is expected to be quickly denitrified or transformed to nitrite and ammonia under the strongly reducing geochemical conditions that are present. Concentrations of organic carbon, the primary constituent of sewage sludge, in sediments of the former sewage lagoon were less than 1 percent, indicating a near absence of organic matter. The amount of total nitrogen present in the sediments at the former sewage lagoon was only about 25 percent of the amount typically present in developed agricultural soils. The lack of substantial carbon and nitrogen in sediments of the former sewage lagoon indicates that surficial sediments of the former lagoon are essentially devoid of residual sewage sludge. The largest concentration of total nitrogen measured in soil samples from the former sewage lagoon (330 milligrams per kilogram) was used to calculate an estimate of the amount of nitrogen that might be leached from residual sewage sludge by recharge. During the first two years following deconstruction of the former sewage lagoon, the concentration of total nitrogen in recharge leachate might exceed 10 milligrams per liter but the recharge leachate would not likely result in substantial increases in the nitrate concentration in ground water to concentrations greater than the drinking-water maximum contaminant level of 10 milligrams per liter.

    Cavitation today is a very important problem that is solved by means of experimental and mathematical methods. The article deals with the generation of cavitation in convergent divergent nozzle of rectangular cross section. Measurement of pressure, flow rate, temperature, amount of dissolved air in the liquid and visualization of cavitation area using high-speed camera was performed for different flow rates. The measurement results were generalized by dimensionless analysis, which allows easy detection of cavitation in the nozzle. For numerical simulation the multiphase mathematical model of cavitation consisting of water and vapor was created. During verification the disagreement with the measurements for higher flow rates was proved, therefore the model was extended to multiphase mathematical model (water, vapor and air), due to release of dissolved air. For the mathematical modeling the multiphase turbulence RNG k-ɛ model for low Reynolds number flow with vapor and air cavitation was used. Subsequently the sizes of the cavitation area were verified. In article the inlet pressure and loss coefficient depending on the amount of air added to the mathematical model are evaluated. On the basis of the approach it may be create a methodology to estimate the amount of released air added at the inlet to the modeled area.

  10. The Office of Naval Research support underrepresented ethnic groups mentoring model redirecting science education: An "investigative" case study

    Garner-Williams, Elizabeth

    While the debate about education in general and science education in particular for every student continues world wide and in the United States of America, the debate points to an underrepresentation of and underachievement by African-Americans (Ferguson, 1981). Given the intent of access to scientific knowledge for every student, the value of scientific knowledge in our society and the fact that the United States of America is a community espousing equal opportunity, it is important to investigate whether or not the situation allows access to scientific knowledge that can be improved through a specific mentoring program for African Americans on historically white university campuses. Education is a cultural process (Gay & Cole, 1966). Each member of a society or a group must learn to act appropriately as a cultural member and contribute to its maintenance and, occasionally to its improvement. The primary aim of education in all societies, either formal or informal, is to provide every citizen with the skills to be self-sufficient and to contribute to the nation's welfare. This is a cultural study of African-American students in a mentoring program. Accordingly, it highlights an understanding of the relationship between schools and communities, educational and social systems, and educational and cultural settings that are meaningful in the present paradigm. The purpose of this dissertation is to investigate the efforts of the Office of Naval Research (ONR) program which mentors African-Americans by redirecting and encouraging them to pursue careers in the scientific fields. The study investigates whether African-American students at Florida State University (FSU), a historically white university, and a participant in the Office of Naval Research (ONR) program, significantly benefits African-American students by providing a mentor with the same cultural background. The study also explores findings that were generated through research to explain the importance of

    Disease spectrum is the study of the composition of types of collective illnesses. Since the 20th century, living standards and lifestyles have changed significantly, so major changes have also occurred in the human disease spectrum. These changes prompt the need for a constantly evolving medical model which is able to adapt to the new disease spectrum. Young adult groups in the naval forces have different age structure, physiques, nature of work, and living conditions from that of the general young adult population. Their work environment is notably different from that of the general population. As such, the changes in disease spectrum of this population must have its own laws and characteristics. In the disease spectrum of naval forces, respiratory diseases and digestive diseases have always occupied an important place. The composition ratio of respiratory diseases has increased from 11.29% in the 1950s to 38.45% in the 1990s, and the composition ratio of digestive diseases has increased from 2.63% to 12.40% in the same time period.%疾病谱是指人群疾病种类的构成.20世纪以来,随着生活水平的提高和生活方式的改变,人类疾病谱发生了重大变迁,促使人们不断地改变医学模式以与其适应.海军部队人员是一个以中青年为主的群体,年龄结构、人群体质、工作性质及生活条件与一般中青年人群不完全相同,尤其是工作环境与普通人群差别很大.所以,该人群疾病谱的变迁有其自身的规律和特点.在海军部队的疾病谱中,呼吸和消化系统疾病始终占据重要位置,呼吸系统疾病的构成比由20世纪50年代的11.29%上升至90年代的38.45%,消化系统疾病的构成比则由2.63%上升至12.40%.

    The U.S. Geological Survey and the Naval Facilities Engineering Command Southeast investigated natural and engineered remediation of chlorinated volatile organic compound groundwater contamination at Solid Waste Management Unit 12 at the Naval Weapons Station Charleston, North Charleston, South Carolina, beginning in 2000. In early 2004, groundwater contaminants began moving around the southern end of a permeable reactive barrier (PRB) installed by a consultant in December 2002. The PRB is a 130-foot-long and 3-foot-wide barrier consisting of varying amounts of zero-valent iron with or without sand mixture. Contamination moving around the PRB probably has been transported at least 75 feet downgradient from the PRB at a rate of about 15 to 29 feet per year.

    In complex industrial process control, causal reasoning appears as a major component in operators` cognitive tasks. It is tightly linked to diagnosis, prediction of normal and failure states, and explanation. This work provides a detailed review of literature in causal reasoning. A synthesis is proposed as a model of causal reasoning in process control. This model integrates distinct approaches in Cognitive Science: especially qualitative physics, Bayesian networks, knowledge-based systems, and cognitive psychology. Our model defines a framework for the analysis of causal human errors in simulated naval nuclear power plant fault management. Through the methodological framework of critical incident analysis we define a classification of errors and difficulties linked to causal reasoning. This classification is based on shallow characteristics of causal reasoning. As an origin of these errors, more elementary component activities in causal reasoning are identified. The applications cover the field of functional specification for man-machine interfaces, operators support systems design as well as nuclear safety. In addition of this study, we integrate the model of causal reasoning in a model of cognitive task in process control. (authors). 106 refs., 49 figs., 8 tabs.

    Naval sonar has been accused of causing whale stranding by a mechanism which increases formation of tissue N2 gas bubbles. Increased tissue and blood N2 levels, and thereby increased risk of decompression sickness (DCS), is thought to result from changes in behavior or physiological responses during diving. Previous theoretical studies have used hypothetical sonar-induced changes in both behavior and physiology to model blood and tissue N2 tension P N 2 , but this is the first attempt to esti...

    Those in the Naval Medical Department are experiencing an exciting time of bridled chaos and creative change. Many mid-career officers are uncertain of the leadership behaviors and skills that will be necessary for successful managerial careers. Changes in the method of health care delivery of this nation combined with the reengineering of the armed forces' world-wide mission has driven military medical leaders to expand their professional skills, knowledge, and abilities beyond the clinical sciences. This research identifies the most critical domains in the science of health care administration and differentiates and ranks job skill, knowledge, and ability requirements that will be necessary for successful health care management into the 21st century. Top Naval hospital executives responded to two iterations of a Delphi inquiry. These medical leaders identified 106 unique issues that were content-analyzed into nine domains by a neutral, expert panel. Domains, in order of ranked importance, were leadership, health care delivery systems, cost-finance, technology, accessibility, professional staff relations, marketing, quality-risk management, and ethics. In the second Delphi iteration, hospital executives reviewed domain results and rated identified job requirements on their required job importance. The top-10 rated skills, knowledge, and abilities are reported. Results indicated that although a business orientation is needed for organizational survival, an emphasis on person-oriented skills, knowledge, and abilities is required for future success as a health care administrator in the Naval health care system.

    Full Text Available In paper there is proposed a new method of historical research, based on analysis of derivatives coefficients of database (for example, the form factor in the database of ballistic data. This method has a much greater protection from subjectivism and direct falsification, compared with the analysis obtained directly from the source of the numerical series, as any intentional or unintentional distortion of the raw data provides a significant contrast ratio derived from the average sample values. Application of this method to the analysis of ballistic data base of naval artillery allowed to find the facts, forcing a new look at some of the events in the history data on the German naval artillery before World War I, probably overpriced for disinformation opponents of the Entente; during the First World War, Spain, apparently held secret talks with the firm Bofors ended purchase of Swedish shells; the first Russian naval rifled guns were created obvious based on the project Blackly, not Krupp as traditionally considered.

  4. Preliminary analysis of surface mining options for Naval Oil Shale Reserve 1

    Energy Technology Data Exchange (ETDEWEB)

    1981-07-20

    The study was undertaken to determine the economic viability of surface mining to exploit the reserves. It is based on resource information already developed for NOSR 1 and conceptual designs of mining systems compatible with this resource. Environmental considerations as they relate to surface mining have been addressed qualitatively. The conclusions on economic viability were based primarily on mining costs projected from other industries using surface mining. An analysis of surface mining for the NOSR 1 resource was performed based on its particular overburden thickness, oil shale thickness, oil shale grade, and topography. This evaluation considered reclamation of the surface as part of its design and cost estimate. The capital costs for mining 25 GPT and 30 GPT shale and the operating costs for mining 25 GPT, 30 GPT, and 35 GPT shale are presented. The relationship between operating cost and stripping ratio, and the break-even stripping ratio (BESR) for surface mining to be competitive with room-and-pillar mining, are shown. Identification of potential environmental impacts shows that environmental control procedures for surface mining are more difficult to implement than those for underground mining. The following three areas are of prime concern: maintenance of air quality standards by disruption, movement, and placement of large quantities of overburden; disruption or cutting of aquifers during the mining process which affect area water supplies; and potential mineral leaching from spent shales into the aquifers. Although it is an operational benefit to place spent shale in the open pit, leaching of the spent shales and contamination of the water is detrimental. It is therefore concluded that surface mining on NOSR 1 currently is neither economically desirable nor environmentally safe. Stringent mitigation measures would have to be implemented to overcome some of the potential environmental hazards.

    Full Text Available Anthropogenic underwater sound in the environment might potentially affect the behavior of marine mammals enough to have an impact on their reproduction and survival. Diving behavior of 5 killer whales (Orcinus orca, 7 long-finned pilot whales (Globicephala melas and 4 sperm whales (Physeter macrocephalus were studied during controlled exposures to naval sonar (LFAS: 1-2 kHz and MFAS: 6-7 kHz during three field seasons (2006-2009. Diving behavior was monitored before, during and after sonar exposure using an archival tag placed on the animal with suction cups. The tag recorded the animal’s vertical movement, and additional data on horizontal movement and vocalizations were used to determine behavioral modes. Killer whales that were conducting deep dives at sonar onset changed abruptly to shallow diving during LFAS, while killer whales conducting deep dives at the onset of MFAS did not alter dive mode. When in shallow diving mode at sonar onset, killer whales did not change their diving behavior. Pilot and sperm whales performed normal deep dives during MFAS exposure. During LFAS exposures, long-finned pilot whales mostly performed fewer deep dives and some sperm whales performed shallower and shorter dives. Acoustic recording data presented previously indicates that deep diving is associated with feeding. Therefore, the observed changes in dive behavior of the three species could potentially reduce the foraging efficiency of the affected animals.

    Anthropogenic underwater sound in the environment might potentially affect the behavior of marine mammals enough to have an impact on their reproduction and survival. Diving behavior of four killer whales (Orcinus orca), seven long-finned pilot whales (Globicephala melas), and four sperm whales (Physeter macrocephalus) was studied during controlled exposures to naval sonar [low frequency active sonar (LFAS): 1-2 kHz and mid frequency active sonar (MFAS): 6-7 kHz] during three field seasons (2006-2009). Diving behavior was monitored before, during and after sonar exposure using an archival tag placed on the animal with suction cups. The tag recorded the animal's vertical movement, and additional data on horizontal movement and vocalizations were used to determine behavioral modes. Killer whales that were conducting deep dives at sonar onset changed abruptly to shallow diving (ShD) during LFAS, while killer whales conducting deep dives at the onset of MFAS did not alter dive mode. When in ShD mode at sonar onset, killer whales did not change their diving behavior. Pilot and sperm whales performed normal deep dives (NDD) during MFAS exposure. During LFAS exposures, long-finned pilot whales mostly performed fewer deep dives and some sperm whales performed shallower and shorter dives. Acoustic recording data presented previously indicates that deep diving (DD) is associated with feeding. Therefore, the observed changes in dive behavior of the three species could potentially reduce the foraging efficiency of the affected animals. PMID:23087648

    2000-11-12

    The Defence Radiological Protection Service (DRPS) is tasked with providing the approved dosimetry service to the Naval Nuclear Propulsion Program (NNPP). Within this requirement, DRPS operates a track-etch system for whole-body neutron dosimetry, using the well-known material polyally dyglycol carbonate as the sensitive element. These dosimeters have a number of limitations, including a high limit of detection (typically 200 microsieverts), insensitivity to low-energy neutrons, and a strong angular dependence. Such limitations, along with the incorporation of the recommendations of the International Commission on Radiological Protection (ICRP) 60 into the revised U.K. Ionizing Radiation Regulations 1999, have provided the opportunity to reconsider spectrometric and dosimetric research in support of the NNPP. Area neutron dosimetry is most usually performed using a Leake-type spherical survey meter. In both the case of area and, more significantly, personal dosimetry, the differences in the energy spectra between the calibration and the operational fields require a location correction factor (LCF) to be applied. To determine these LCFs, it is necessary to accurately characterize the operational energy spectra. This characterization is undertaken using the transportable neutron spectrometer (TNS) developed by the U.K. Atomic Energy Establishment at Winfrith in the 1980s. Our research has focused on two areas, the development of an improved TNS system and a complimentary program to design a new area survey meter.

    This report describes in detail the experience gained and lessons learned from the 6-kW grid-integrated Wind Energy Conversion System (WECS) demonstration at Naval Station, Treasure Island, San Francisco Bay. The objective of this demonstration was to develop operating experience and maintenance information on the 6-kW WECS using a combination of permanent magnet alternator with a line commutated synchronous inverter. The on-site measurements conducted during the demonstation indicate that the WECS site has annual average windspeeds of about 8 to 10 mph. The test results to data indicate a satisfactory performance of the WECS except for two failures involving arcing at the electrical terminals located on the yaw shaft. Due to wind characteristics encountered at the site, the performance data collected to date are at windspeeds of 20 mph or lower. For evaluating the WECS performance at all windspeeds, location at a windier site with annual average windspeeds of 14 mph or higher is recommended.

  11. Proposed natural gas protection program for Naval Oil Shale Reserves Nos. 1 and 3, Garfield County, Colorado

    Energy Technology Data Exchange (ETDEWEB)

    1991-08-01

    As a result of US Department of Energy (DOE) monitoring activities, it was determined in 1983 that the potential existed for natural gas resources underlying the Naval Oil Shales Reserves Nos. 1 and 3 (NOSrs-1 3) to be drained by privately-owned gas wells that were being drilled along the Reserves borders. In 1985, DOE initiated a limited number of projects to protect the Government's interest in the gas resources by drilling its own offset production'' wells just inside the boundaries, and by formally sharing in the production, revenues and costs of private wells that are drilled near the boundaries ( communitize'' the privately-drilled wells). The scope of these protection efforts must be expanded. DOE is therefore proposing a Natural Gas Protection Program for NOSRs-1 3 which would be implemented over a five-year period that would encompass a total of 200 wells (including the wells drilled and/or communitized since 1985). Of these, 111 would be offset wells drilled by DOE on Government land inside the NOSRs' boundaries and would be owned either entirely by the Government or communitized with adjacent private land owners or lessees. The remainder would be wells drilled by private operators in an area one half-mile wide extending around the NOSRs boundaries and communitized with the Government. 23 refs., 2 figs., 6 tabs.

  12. Application of pulsed tandem gas metal arc welding for fabrication of high strength steel panels in naval surface vessels

    International Nuclear Information System (INIS)

    Pulsed tandem gas metal arc welding (PT-GMAW) has been identified as a process that is potentially capable of increasing productivity and minimising distortion in the fabrication of surface ship panels. For this study, the PT-GMAW process was used in pulse pulse mode to butt-weld 8 MM HSLA65 steel plate in order to determine its suitability as a replacement for standard gas-metal-arc welding (GMAW) and submerged-arc welding (SAW) in naval shipbuilding. In the pulse-pulse mode, the leading and trailing welding wires alternately transfer metal into a single molten weld pool at deposition rates or travel speeds greater than those used in conventional single-wire arc welding processes. The results showed that the lowest level of distortion occurred in a single-bead butt weld using PT-GMAW. Higher levels of distortion were measured after square-butt welding using double-bead PT-GMAW, with one bead per side; and applying standard GMAW multiple-bead butt welding with a single-V preparation. Although the magnitude of the maximum tensile residual stresses was similar for all welds, the single-bead weld rising PT-GMAW resulted in the largest region of high tensile residual stresses (>500 MPa) in the longitudinal direction. Nevertheless, it showed the lowest distortion and the strength, hardness and impact toughness were similar to those of the double-bead PT-GMAW weldment and the standard GMAW weldment.

    International Nuclear Information System (INIS)

    Radionuclide inventories have bin estimated for the reactor cores, reactor components, and primary system corrosion products in the former Soviet Union naval reactors dumped at the Abrosimov Inlet, Tsivolka Inlet, Stepovoy Inlet, Techeniye Inlet, and Novaya Zemlya Depression sites in the Kara Sea between 1965 and 1988. For the time of disposal, the inventories are estimated at 17 to 66 kCi of actinides plus daughters and 1695 to 4782 kCi of fission products in the reactor cores, 917 to 1127 kCi of activation products in the reactor components, and 1.4 to 1.6 kCi of activation products in the primary system corrosion products. At the present time, the inventories are estimated to have decreased to 6 to 24 kCi of actinides plus daughters and 492 to 540 kCi of fission products in the reactor cores, 124 to 126 kCi of activation products in the reactor components, and 0.16 to 0.17 kCi of activation products in the primary system corrosion products. All actinide activities are estimated to be within a factor of two

  20. Emergency air supply

    International Nuclear Information System (INIS)

    An air supply safety device is described which can operate in an hostile environment. The system ensures that should the ring mains supply or the operator's individual hose fail an emergency air supply is obtained from a compressed air bottle fed to the operator's face mask via a valve. The valve switches from mains/mask to emergency supply/mask when the mains pressure falls below the emergency supply pressure. (U.K.)
