    2005-02-01

    The volumetric efficiency and power of internal combustion engines is improved with an intake port having an intake nozzle, a venturi, and a surge chamber. The venturi is located almost halfway upstream the intake port between the intake valves and the intake plenum enabling the venturi throat diameter to be exceptionally small for providing an exceptionally high ram velocity and an exceptionally long and in turn high efficiency diffuser flowing into the surge chamber. The intake port includes an exceptionally large surge chamber volume for blow down of the intake air into the working cylinder of the engine.

  2. Jet engine air intake system

    1977-01-01

    An axisymmetric air intake system for a jet aircraft engine comprising a fixed cowl extending outwardly from the face of the engine, a centerbody coaxially disposed within the cowl, and an actuator for axially displacing the centerbody within the cowl was developed. The cowl and centerbody define a main airflow passageway therebetween, the configuration of which is changed by displacement of the centerbody. The centerbody includes a forwardly-located closeable air inlet which communicates with a centerbody auxiliary airflow passageway to provide auxiliary airflow to the engine. In one embodiment, a system for opening and closing the centerbody air inlet is provided by a dual-member centerbody, the forward member of which may be displaced axially with respect to the aft member.

    This paper presents a KIVA-3 code based numerical model for three-dimensional transient intake flow in the intake port-valve-cylinder system of internal combustion engine using body-fitted technique, which can be used in numerical study on internal combustion engine with vertical and inclined valves, and has higher calculation precision. A numerical simulation (on the intake process of a two-valve engine with a semi-sphere combustion chamber and a radial intake port) is provided for analysis of the velocity field and pressure field of different plane at different crank angles. The results revealed the formation of the tumble motion, the evolution of flow field parameters and the variation of tumble ratios as important information for the design of engine intake system.

  17. A study on the effects of the intake port configurations on the swirl flow generated in a small D.I. diesel engine

    This paper investigates the effect of intake port configuration on the swirl that is generated within a direct injection (D.I.) diesel engine. The in-cylinder flow characteristics are known to have significant effects on fuel-air mixing, combustion, and emissions. To clarify how to intensify the swirl flow, a swirl control valve (SCV) and a bypass were selected as design parameters for enhancing the swirl flow. The optimal intake port shape was also chosen as a parameter needed to efficiently generate a high swirl ratio. The results revealed that a key factor in generating a high swirl ratio was to control the intake airflow direction passing through the intake valve seat. Further, the swirl intensity was influenced by changing the distance between the helical and tangential ports, and the swirl flow was changed by the presence of a bypass near the intake valve seat. Additionally, the effect of intake port geometry on the in-cylinder flow field was investigated by using a laser sheet visualization method. The experimental results showed a correlation of swirl ratio and mass flow rate. In addition, we found that employing the bypass was an effective method to increase swirl ratio without sacrificing mass flow rate.

  5. Assessment of ambient air quality in the port of Naples.

    Two experimental monitoring campaigns were carried out in 2012 to investigate the air quality in the port of Naples, the most important in southern Italy for traffic of passengers and one of the most important for goods. Therefore, it represents an important air pollution source located close to the city of Naples. The concentrations of sulfur dioxide (SO₂), nitrogen dioxide (NO₂), and BTEX (benzene, toluene, ethylbenzene, and xylenes) in the air were measured at 15 points inside the Naples port area through the use of passive samplers. In addition, a mobile laboratory was positioned in a fixed point inside the port area to measure continuous concentration of pollutants together with particulate matter, ambient parameters, and wind direction and intensity. The pollution levels monitored were compared with those observed in the urban area of Naples and in other Mediterranean ports. Even though the observation time was limited, measured concentrations were also compared with limit values established by European legislation. All the measured pollutants were below the limits with the exception of nitrogen dioxide: its average concentration during the exposition time exceeded the yearly limit value. A spatial analysis of data, according to the measured wind direction and intensity, provided information about the effects that ship emissions have on ambient air quality in the port area. The main evidence indicates that ship emissions influence sulfur dioxide concentration more than any other pollutants analyzed. PMID:26029862

  11. Air intake side secondary air supply system for an internal combustion engine

    SciTech Connect

    Kobayashi, H.; Tomobe, N.

    1987-03-10

    This patent describes an air intake side secondary air supply system for an internal combustion engine having a choke valve and a throttle valve in an intake air passage. The system is adapted to supply an air intake side secondary air into an intake air passage downstream of the throttle valve by a control valve and in response to an operating condition of the engine during a cold operation of the engine. The improvement described here comprises means for detecting a no-load operating state of the engine during the cold operation of the engine in which the choke valve is actuated to close the intake air passage, and means for stopping a supply of the air intake side secondary air upon detection of the non-load operating state so as to enrich an air-fuel mixture supplied to the engine.

    1984-01-17

    A gas turbine engine and its associated air intake system are disclosed in which the air intake system comprises a generally horizontally extending duct through which an airflow is induced by an ejector pump powered by the engine. A portion of the air passing through the duct is directed through a second duct to the air inlet of the engine. The second duct is connected to the first duct in such a manner that the air directed to the engine air inlet is derived from a vertically upper region of the first duct. The arrangement is intended to reduce the amount of airborne particulate material ingested by the gas turbine engine.

  13. Air pollution from ships in three Danish ports

    NASA Astrophysics Data System (ADS)

    Saxe, H.; Larsen, T.

    The operational meteorological air quality model (OML) was used to calculate the urban dispersion of air pollutants originating from ships in three Danish ports: Copenhagen, Elsinore and Køge. Oxides of nitrogen (NO x=NO+NO 2) emitted by ships in the port of Copenhagen contributed substantially to the overall NO x pollution in central Copenhagen. This would have an impact on human health if most of the NO were occasionally transformed into NO 2, for which the European Community's legal limit is defined by the 19th-highest annual hourly value being 200 μg m -3 NO 2. Emissions by the ships caused a maximum 19th hourly NO x concentration of 615 μg m -3. In a small area of housing estates and office blocks near the harbour, it exceeded 200 μg m -3 NO x, and over several square kilometres of central Copenhagen, the emission by ships in harbour similarly caused values of 50-200 μg m -3 NO x. In the port of Elsinore, ferries contributed significantly to the NO x pollution in the neighbourhood around the harbour. Emissions of particulate matter (PM) by ships in Copenhagen harbour caused neighbourhood concentrations equivalent to only 0.2-0.4% of the European Community's legal annual mass-based limit value for the protection of human health. However, ship emissions are dominated by ultrafine particles, as are diesel vehicle emissions, which adversely affect human health. Particulate emissions from ships contribute 8-15% of that of all urban road traffic to the background PM 10 levels in the harbour neighbourhoods. In Elsinore, the PM problem was less significant than in Copenhagen. Ships in both harbours will contribute insignificantly to urban pollution with sulphur dioxide (SO 2), once the anticipated regulations on sulphur content in marine fuels are implemented. In Køge, the low activity in the harbour meant that ships did not significantly affect urban air quality.

  14. Synergistic air port corrosion in kraft recovery boilers

    SciTech Connect

    Holcomb, Gordon R.

    2001-08-01

    Localized hot corrosion can occur on the cold-side of air-ports in Kraft recovery boilers. Depending on the basicity of the molten salt, either acidic or basic fluxing takes place, with a solubility minima at the transition between the two reactions. For stainless steel, if the basicity of the fused salt is between the iron and chromium oxide solubility minima, then a synergistic effect can occur that leads to rapid corrosion. The products of one reaction are the reactants of the other, which eliminates the need for rate-controlling diffusion. This effect can explain why stainless steel is attacked more readily than carbon steel.

  16. Cracking of Composite Modified Alloy 825 Primary Air Port Tubes

    SciTech Connect

    Kish, Joseph R.; Keiser, James R; Singbeil, Douglas; Willoughby, Adam W; Longmire, Hu Foster

    2007-04-01

    Twenty primary air ports fabricated from modified Alloy 825-based composite tubes underwent a metallurgical examination to document the mode and extent of cracking on the external fireside surface of a kraft recovery boiler. Collectively, the crack features found are most consistent with thermal fatigue, but corrosion fatigue cannot be ruled out. Regardless of the true cracking mechanism, temperature cycling is implicated as a critical factor for crack propagation. on the basis of the relative crack lengths observed, membrane welds and tube weld repairs, and their adjacent heat-affected zones, appear to be more susceptible to cracking than the cladding itself. This work suggests that mills should avoid boiler operating conditions that promote large temperature fluctuations, which can cause Alloy 825-based composite tubes to crack.

    A new camless compressed air engine is proposed, which can make the compressed air energy reasonably distributed. Through analysis of the camless compressed air engine, a mathematical model of the working processes was set up. Using the software MATLAB/Simulink for simulation, the pressure, temperature, and air mass of the cylinder were obtained. In order to verify the accuracy of the mathematical model, the experiments were conducted. Moreover, performance analysis was introduced to design compressed air engine. Results show that, firstly, the simulation results have good consistency with the experimental results. Secondly, under different intake pressures, the highest output power is obtained when the crank speed reaches 500 rpm, which also provides the maximum output torque. Finally, higher energy utilization efficiency can be obtained at the lower speed, intake pressure, and valve duration angle. This research can refer to the design of the camless valve of compressed air engine. PMID:25379536

    An inlet for a gas turbine engine was disposed about a curved centerline for the purpose of accepting intake air that is flowing at an angle to engine centerline and progressively turning that intake airflow along a curved path into alignment with the engine. This curved inlet is intended for use in under the wing locations and similar regions where airflow direction is altered by aerodynamic characteristics of the airplane. By curving the inlet, aerodynamic loss and acoustic generation and emission are decreased.

    A turbocharged V type engine can be equipped with an exhaust gas recirculation cooler integrated into the intake manifold, so as to achieve efficiency, cost reductions and space economization improvements. The cooler can take the form of a tube-shell heat exchanger that utilizes a cylindrical chamber in the air intake manifold as the heat exchanger housing. The intake manifold depends into the central space formed by the two banks of cylinders on the V type engine, such that the central space is effectively utilized for containing the manifold and cooler.

  8. Effect of Intake Air Filter Condition on Light-Duty Gasoline Vehicles

    SciTech Connect

    Thomas, John F; Huff, Shean P; West, Brian H; Norman, Kevin M

    2012-01-01

    Proper maintenance can help vehicles perform as designed, positively affecting fuel economy, emissions, and the overall drivability. This effort investigates the effect of one maintenance factor, intake air filter replacement, with primary focus on vehicle fuel economy, but also examining emissions and performance. Older studies, dealing with carbureted gasoline vehicles, have indicated that replacing a clogged or dirty air filter can improve vehicle fuel economy and conversely that a dirty air filter can be significantly detrimental to fuel economy. The effect of clogged air filters on the fuel economy, acceleration and emissions of five gasoline fueled vehicles is examined. Four of these were modern vehicles, featuring closed-loop control and ranging in model year from 2003 to 2007. Three vehicles were powered by naturally aspirated, port fuel injection (PFI) engines of differing size and cylinder configuration: an inline 4, a V6 and a V8. A turbocharged inline 4-cylinder gasoline direct injection (GDI) engine powered vehicle was the fourth modern gasoline vehicle tested. A vintage 1972 vehicle equipped with a carburetor (open-loop control) was also examined. Results reveal insignificant fuel economy and emissions sensitivity of modern vehicles to air filter condition, but measureable effects on the 1972 vehicle. All vehicles experienced a measured acceleration performance penalty with clogged intake air filters.

  9. Measuring Outdoor Air Intake Rates into Existing Building

    SciTech Connect

    Fisk, William; Sullivan, Douglas; Cohen, Sebastian; Han, Hwataik

    2009-04-16

    Practical and accurate technologies are needed for continuously measuring and controlling outdoor air (OA) intake rates in commercial building heating, ventilating, and air conditioning (HVAC) systems. This project evaluated two new measurement approaches. Laboratory experiments determined that OA flow rates were measurable with errors generally less than 10 percent using electronic air velocity probes installed between OA intake louver blades or at the outlet face of louvers. High accuracy was maintained with OA flow rates as low as 15 percent of the maximum for the louvers. Thus, with this measurement approach HVAC systems do not need separate OA intakes for minimum OA supply. System calibration parameters are required for each unique combination of louver type and velocity sensor location but calibrations are not necessary for each system installation. The research also determined that the accuracy of measuring OA flow rates with velocity probes located in the duct downstream of the intake louver was not improved by installing honeycomb airflow straighteners upstream of the probes. Errors varied with type of upstream louver, were as high as 100 percent, and were often greater than 25 percent. In conclusion, use of electronic air velocity probes between the blades of OA intake louvers or at the outlet face of louvers is a highly promising means of accurately measuring rates of OA flow into HVAC systems. The use of electronic velocity probes downstream of airflow straighteners is less promising, at least with the relatively small OA HVAC inlet systems employed in this research.

  10. Experimental Studies on High Speed Air Intakes

    NASA Astrophysics Data System (ADS)

    Panigrahy, Amit Kumar; Muruganandam, T. M.

    All high speed air breathing engines require an inlet to decelerate air from free stream velocity to a lower velocity conducive to combustion. The inlet is designed to capture and deliver the required mass flow to combustion chamber with minimum pressure loss, along with minimum flow distortion. Inlet buzz can occur due to several reasons, such as large internal area contraction ratio, serious shock-boundary layer interactions, and high back pressure. Inlet buzz is detrimental to thrust and can even cause structural damage. Thus a detailed back pressure and over contraction based study of inlet behavior is needed.

    The methods employed to test air intakes for a supersonic guided ramjet powered missile being tested by ONERA are described. Both flight tests and wind tunnel tests were performed on instrumented rockets to verify the designs. Consideration as given to the number of intakes, with the goal of delivering the maximum pressure to the engine. The S2, S4, and S5 wind tunnels were operated at Mach nos. 1.5-3 for the tests, which were compartmentalized into fuselage-intake interaction, optimization of the intake shapes, and the intake performance. Tests were performed on the length and form of the ogive, the presence of grooves, the height of traps in the boundary layer, the types and number of intakes and the lengths and forms of diffusers. Attention was also given to the effects of sideslip, effects of the longitudinal and circumferential positions of the intakes were also examined. Near optimum performance was realized during Mach 2.2 test flights of the prototype rockets.

    The disturbed-rock zone surrounding the air-intake shaft at the Waste Isolation Pilot Plant (WIPP) site was investigated to determine the extent and the permeability of the disturbed-rock zone as a function of radial distance from the 6.1 m diameter shaft, at different elevations within the Salado. Gas- and brine-permeability tests were performed in the bedded halite of the Salado formation at two levels within the air-intake shaft. The gas- and brine-permeability test results demonstrated that the radial distance to an undisturbed formation permeability of 1 {times} 10{sup {minus}21} m{sup 2} was less than 3.0 m.

    Air pollution from freshwater port is mainly caused by dust pollution, including material loading and unloading dust, road dust, and wind erosion dust from stockpile, bare soil. The dust pollution from a single dock characterized in obvious difference with air pollution from multiple scattered docks. Jining Port of Shandong Province was selected as a case study to get superposition impact contribution of air pollution for regional air environment from multiple scattered docks and to provide technical support for system evaluation of port air pollution. The results indicate that (1) the air pollution from freshwater port occupies a low proportion of pollution impact on regional environmental quality because the port is consisted of serveral small scattered docks; (2) however, the geometric center of the region distributed by docks is severely affected with the most superposition of the air pollution; and (3) the ADMS model is helpful to attain an effective and integrated assessment to predict a superposition impact of multiple non-point pollution sources when the differences of high-altitude weather conditions was not considered on a large scale.

  9. Inhalation intake of ambient air pollution in California's South Coast Air Basin

    NASA Astrophysics Data System (ADS)

    Marshall, Julian D.; Granvold, Patrick W.; Hoats, Abigail S.; McKone, Thomas E.; Deakin, Elizabeth; W Nazaroff, William

    Reliable estimates of inhalation intake of air pollution and its distribution among a specified population are important for environmental epidemiology, health risk assessment, urban planning, and environmental policy. We computed distributional characteristics of the inhalation intake of five pollutants for a group of ˜25,000 people (˜29,000 person-days) living in California's South Coast Air Basin. Our approach incorporates four main inputs: temporally resolved information about people's location (latitude and longitude), microenvironment, and activity level; temporally and spatially explicit model determinations of ambient concentrations; stochastically determined microenvironmental adjustment factors relating the exposure concentration to the ambient concentration; and, age-, gender-, and activity-specific breathing rates. Our study is restricted to pollutants of outdoor origin, i.e. it does not incorporate intake in a microenvironment from direct emissions into that microenvironment. Median estimated inhalation intake rates (μg d -1) are 53 for benzene, 5.1 for 1,3-butadiene, 8.7×10 -4 for hexavalent chromium in fine particulate matter (Cr-PM 2.5), 30 for diesel fine particulate matter (DPM 2.5), and 68 for ozone. For the four primary pollutants studied, estimated median intake rates are higher for non-whites and for individuals in low-income households than for the population as a whole. For ozone, a secondary pollutant, the reverse is true. Accounting for microenvironmental adjustment factors, population mobility and temporal correlations between pollutant concentrations and breathing rates affects the estimated inhalation intake by 40% on average. The approach presented here could be extended to quantify the impact on intakes and intake distributions of proposed changes in emissions, air quality, and urban infrastructure.

  18. Variable oxygen/nitrogen enriched intake air system for internal combustion engine applications

    DOEpatents

    Poola, Ramesh B.; Sekar, Ramanujam R.; Cole, Roger L.

    1997-01-01

    An air supply control system for selectively supplying ambient air, oxygen enriched air and nitrogen enriched air to an intake of an internal combustion engine includes an air mixing chamber that is in fluid communication with the air intake. At least a portion of the ambient air flowing to the mixing chamber is selectively diverted through a secondary path that includes a selectively permeable air separating membrane device due a differential pressure established across the air separating membrane. The permeable membrane device separates a portion of the nitrogen in the ambient air so that oxygen enriched air (permeate) and nitrogen enriched air (retentate) are produced. The oxygen enriched air and the nitrogen enriched air can be selectively supplied to the mixing chamber or expelled to atmosphere. Alternatively, a portion of the nitrogen enriched air can be supplied through another control valve to a monatomic-nitrogen plasma generator device so that atomic nitrogen produced from the nitrogen enriched air can be then injected into the exhaust of the engine. The oxygen enriched air or the nitrogen enriched air becomes mixed with the ambient air in the mixing chamber and then the mixed air is supplied to the intake of the engine. As a result, the air being supplied to the intake of the engine can be regulated with respect to the concentration of oxygen and/or nitrogen.

  19. Effect of Intake Air Filter Condition on Vehicle Fuel Economy

    2009-02-01

    The U.S. Department of Energy (DOE) Office of Energy Efficiency and Renewable Energy and the U.S. Environmental Protection Agency (EPA) jointly maintain a fuel economy website (www.fueleconomy.gov), which helps fulfill their responsibility under the Energy Policy Act of 1992 to provide accurate fuel economy information [in miles per gallon (mpg)] to consumers. The site provides information on EPA fuel economy ratings for passenger cars and light trucks from 1985 to the present and other relevant information related to energy use such as alternative fuels and driving and vehicle maintenance tips. In recent years, fluctuations in the price of crude oil and corresponding fluctuations in the price of gasoline and diesel fuels have renewed interest in vehicle fuel economy in the United States. (User sessions on the fuel economy website exceeded 20 million in 2008 compared to less than 5 million in 2004 and less than 1 million in 2001.) As a result of this renewed interest and the age of some of the references cited in the tips section of the website, DOE authorized the Oak Ridge National Laboratory (ORNL) Fuels, Engines, and Emissions Research Center (FEERC) to initiate studies to validate and improve these tips. This report documents a study aimed specifically at the effect of engine air filter condition on fuel economy. The goal of this study was to explore the effects of a clogged air filter on the fuel economy of vehicles operating over prescribed test cycles. Three newer vehicles (a 2007 Buick Lucerne, a 2006 Dodge Charger, and a 2003 Toyota Camry) and an older carbureted vehicle were tested. Results show that clogging the air filter has no significant effect on the fuel economy of the newer vehicles (all fuel injected with closed-loop control and one equipped with MDS). The engine control systems were able to maintain the desired AFR regardless of intake restrictions, and therefore fuel consumption was not increased. The carbureted engine did show a decrease in

    The duration of use is usually significantly longer for marine vessels than for roadside vehicles. Therefore, these vessels are often powered by relatively old engines which may propagate air pollution. Also, the quality of fuel used for marine vessels is usually not comparable to the quality of fuels used in the automotive sector and therefore, port areas may exhibit a high degree of air pollution. In contrast to the multitude of studies that addressed outdoor air pollution due to road traffic, only little is known about ship-related air pollution. Therefore the present article aims to summarize recent studies that address air pollution, i.e. particulate matter exposure, due to marine vessels. It can be stated that the data in this area of research is still largely limited. Especially, knowledge on the different air pollutions in different sea areas is needed. PMID:22141925

    A system for conditioning the intake air to an internal combustion engine includes a means to boost the pressure of the intake air to the engine and a liquid cooled charge air cooler disposed between the output of the boost means and the charge air intake of the engine. Valves in the coolant system can be actuated so as to define a first configuration in which engine cooling is performed by coolant circulating in a first coolant loop at one temperature, and charge air cooling is performed by coolant flowing in a second coolant loop at a lower temperature. The valves can be actuated so as to define a second configuration in which coolant that has flowed through the engine can be routed through the charge air cooler. The temperature of intake air to the engine can be controlled over a wide range of engine operation.

    Poola, Ramesh B.; Sekar, Ramanujam R.; Stork, Kevin C.

    1997-01-01

    An oxygen-enriched air intake control system for an internal combustion engine includes air directing apparatus to control the air flow into the intake of the engine. During normal operation of the engine, ambient air flowing from an air filter of the engine flows through the air directing apparatus into the intake of the engine. In order to decrease the amount of carbon monoxide (CO) and hydrocarbon (HC) emissions that tend to be produced by the engine during a short period of time after the engine is started, the air directing apparatus diverts for a short period of time following the start up of the engine at least a portion of the ambient air from the air filter through a secondary path. The secondary path includes a selectively permeable membrane through which the diverted portion of the ambient air flows. The selectively permeable membrane separates nitrogen and oxygen from the diverted air so that oxygen enriched air containing from about 23% to 25% oxygen by volume is supplied to the intake of the engine.

    2015-01-01

    The widespread absence of systems for real-time measurement and feedback control, of minimum outdoor air intake rates in HVAC systems contributes to the poor control of ventilation rates in commercial buildings. Ventilation rates affect building energy consumption and influence occupant health. The project designed fabricated and tested four prototypes of systems for measuring rates of outdoor air intake into roof top air handlers. All prototypes met the ±20% accuracy target at low wind speeds, with all prototypes accurate within approximately ±10% after application of calibration equations. One prototype met the accuracy target without a calibration. With two of four prototype measurement systems, there was no evidence that wind speed or direction affected accuracy; however, winds speeds were generally below usually 3.5 m s-1 (12.6 km h-1) and further testing is desirable. The airflow resistance of the prototypes was generally less than 35 Pa at maximum RTU air flow rates. A pressure drop of this magnitude will increase fan energy consumption by approximately 4%. The project did not have resources necessary to estimate costs of mass produced systems. The retail cost of components and materials used to construct prototypes ranged from approximately $1,200 to $1,700. The test data indicate that the basic designs developed in this project, particularly the designs of two of the prototypes, have considerable merit. Further design refinement, testing, and cost analysis would be necessary to fully assess commercial potential. The designs and test results will be communicated to the HVAC manufacturing community.

    This patent describes an internal combustion engine, means defining a cylinder closed at one end and having an axis, means defining an inlet passage through the cylinder defining means and communicating with the cylinder through the closed end, and a poppet inlet valve including a stem and head having a valve axis and disposed in the passage for reciprocation on the valve axis to control communication of the inlet passage with the cylinder. The inlet passage is characterized by: a throat of generally circular cross-section opening into the cylinder and adapted to be closed by the inlet valve, an entrance portion spaced from the throat and offset from the valve axis, and means defining a fluid flow path extending from the entrance portion toward and around opposite sides of the valve axis and below the valve head when open to the throat. The fluid flow path defines means having a top wall including first and second ramp portions and a shelf portion spaced from and opposite the throat, the ramp portions sloping downwardly and merging with the shelf portion on generally opposite sides of the valve axis. The ramp portions lie at steep angles to the shelf portion and one of the ramp portions having a substantially steeper angle than the other to slow and direct downwardly fluid flow passing the one of the sides of the valve axis below the one steeper ramp relative to the higher speed and less downward direction of flow passing the other of the sides of the valve axis, whereby preferential entry of swirl developing flow into the shelf area from below the ramp of lower slope is encouraged.

    The Bay Area Air Quality Management District (BAAQMD) sponsored the West Oakland Monitoring Study (WOMS) to provide supplemental air quality monitoring that will be used by the BAAQMD to evaluate local-scale dispersion modeling of diesel emissions and other toxic air contaminants for the area within and around the Port of Oakland. The WOMS was conducted during two seasonal periods of 4 weeks in summer 2009 and winter 2009/2010. Monitoring data showed spatial patterns of pollutant concentrations that were generally consistent with proximity to vehicle traffic. Concentrations of directly emitted pollutants were highest on heavily traveled roads with consistently lower concentrations away from the roadways. Pollutants that have higher emission rates from diesel trucks (nitric oxide, black carbon) tended to exhibit sharper gradients than pollutants that are largely associated with gasoline vehicles, such as carbon monoxide and volatile organic compounds, including benzene, toluene, ethylbenzene, and xylenes (BTEX). BTEX concentrations in West Oakland were similar to those measured at the three air toxics monitoring network sites in the Bay Area (San Francisco, Fremont, and San Jose). Aldehyde levels were higher in Fremont and San Jose than in West Oakland, reflecting greater contributions from photo-oxidation of hydrocarbons downwind of the Bay Area. A 2005 modeling-based health risk assessment of diesel particulate matter concentrations is consistent with aerosol carbon concentrations measured during the WOMS after adjusting for recent mitigation measures and improved estimates of heavy-duty truck traffic volumes.

  12. An Ejector Air Intake Design Method for a Novel Rocket-Based Combined-Cycle Rocket Nozzle

    NASA Astrophysics Data System (ADS)

    Waung, Timothy S.

    Rocket-based combined-cycle (RBCC) vehicles have the potential to reduce launch costs through the use of several different air breathing engine cycles, which reduce fuel consumption. The rocket-ejector cycle, in which air is entrained into an ejector section by the rocket exhaust, is used at flight speeds below Mach 2. This thesis develops a design method for an air intake geometry around a novel RBCC rocket nozzle design for the rocket-ejector engine cycle. This design method consists of a geometry creation step in which a three-dimensional intake geometry is generated, and a simple flow analysis step which predicts the air intake mass flow rate. The air intake geometry is created using the rocket nozzle geometry and eight primary input parameters. The input parameters are selected to give the user significant control over the air intake shape. The flow analysis step uses an inviscid panel method and an integral boundary layer method to estimate the air mass flow rate through the intake geometry. Intake mass flow rate is used as a performance metric since it directly affects the amount of thrust a rocket-ejector can produce. The design method results for the air intake operating at several different points along the subsonic portion of the Ariane 4 flight profile are found to under predict mass flow rate by up to 8.6% when compared to three-dimensional computational fluid dynamics simulations for the same air intake.

    Black liquor recovery boilers are an essential part of kraft mills. Their design and operating procedures have changed over time with the goal of providing improved boiler performance. These performance improvements are frequently associated with an increase in heat flux and/or operating temperature with a subsequent increase in the demand on structural materials associated with operation at higher temperatures and/or in more corrosive environments. Improvements in structural materials have therefore been required. In most cases the alternate materials have provided acceptable solutions. However, in some cases the alternate materials have solved the original problem but introduced new issues. This report addresses the performance of materials in the tubes forming primary air port openings and, particularly, the problems associated with use of stainless steel clad carbon steel tubes and the solutions that have been identified.

    This paper presents results of emission tests of a flexible fuel vehicle (FFV) powered by an SI engine, fueled by M85 (methanol), and supplied with oxygen-enriched intake air containing 21, 23, and 25 vol% O2. Engine-out total hydrocarbons (THCs) and unburned methanol were considerably reduced in the entire FTP cycle when the O2 content of the intake air was either 23 or 25%. However, CO emissions did not vary much, and NOx emissions were higher. HCHO emissions were reduced by 53% in bag 1, 84% in bag 2, and 59% in bag 3 of the FTP cycle with 25% oxygen-enriched intake air. During cold-phase FTP,reductions of 42% in THCs, 40% in unburned methanol, 60% in nonmethane hydrocarbons, and 45% in nonmethane organic gases (NMOGs) were observed with 25% enriched air; NO{sub x} emissions increased by 78%. Converter-out emissions were also reduced with enriched air but to a lesser degree. FFVs operating on M85 that use 25% enriched air during only the initial 127 s of cold-phase FTP or that use 23 or 25% enriched air during only cold-phase FTP can meet the reactivity-adjusted NMOG, CO, NO{sub x}, and HCHO emission standards of the transitional low-emission vehicle.

    Port causes environmental and health concerns in coastal cities if its operation and development are not made environmentally compatible and sustainable. An emission inventory is necessary to assess the impact of port projects or growth in marine activity as well as to plan mitigation strategies. In this study, a detailed emission inventory of total suspended particulate (TSP) matter, respirable particulate matter (PM(10)), sulphur dioxide (SO(2)) and oxides of nitrogen (NO(x)) for a port having operation and construction activities in parallel is compiled. The study has been done for 1 year. Results show that the maximum contribution of emission of air pollutants in the port area was from TSP (68.5%) and the minimum was from SO(2) (5.3%) to the total pollutants considered in this study. Total TSP emission from all activities of the port was 4,452 tyr(-1) and PM(10) emission was 903 tyr(-1) in the year 2006. Re-suspension of dust from paved roads was the major contributor of TSP and PM(10) in the road transport sector. Construction activities of the port had contributed 3.9% of TSP and 7.4% of PM(10) to total emission of particulate matter. Of the total particulate emissions from various port activities approximately 20% of TSP could be attributed to PM(10). The sectoral composition indicates that major contribution of SO(2) emission in the port was from maritime sector and major contribution of NO(x) was from road transport sector. PMID:19030999

    Intake fractions, an emissions-intake relationship for primary pollutants, are defined and are estimated in order to make simple estimates of health damages from air pollution. The sulfur dioxide (SO2) and total suspended particles (TSP) intake fractions for five cities of China are estimated for the four main polluting industries-electric power generation, mineral (mostly cement) products industry, chemical process industry and metallurgical industry (mainly iron and steel smelting). The Industrial Source Complex Long Term (ISTLT3) model is used to simulate the spatial distribution of incremental ambient concentrations due to emissions from a large sample of site-specific sources. Detailed population distribution information is used for each city. The average intake fractions within 50 km of these sources are 4.4x10(-6) for TSP, and 4.2x10(-6) for SO2, with standard deviations of 8.15x10(-6) and 9.16x10(-6), respectively. They vary over a wide range, from 10(-7) to 10(-5). Although the electric power generation has been the focus of much of the air pollution research in China, our results show that it has the lowest average intake fraction for a local range among the four industries, which highlights the importance of pollutant emissions from other industrial sources. Sensitivity analyses show how the intake fractions are affected by the source and pollutant characteristics, the most important parameter being the size of the domain. However, the intake fraction estimates are robust enough to be useful for evaluating the local impacts on human health of primary SO2 and TSP emissions. An application of intake fractions is given to demonstrate how this approach provides a rapid population risk estimate if the dose-response function is linear without threshold, and hence can help in prioritizing pollution control efforts.

    2013-01-01

    The flow control in twin air-intakes is necessary to improve the performance characteristics, since the flow traveling through curved and diffused paths becomes complex, especially after merging. The paper presents a comparison between two well-known techniques of flow control: active and passive. It presents an effective design of a vortex generator jet (VGJ) and a vane-type passive vortex generator (VG) and uses them in twin air-intake duct in different combinations to establish their effectiveness in improving the performance characteristics. The VGJ is designed to insert flow from side wall at pitch angle of 90 degrees and 45 degrees. Corotating (parallel) and counterrotating (V-shape) are the configuration of vane type VG. It is observed that VGJ has the potential to change the flow pattern drastically as compared to vane-type VG. While the VGJ is directed perpendicular to the side walls of the air-intake at a pitch angle of 90 degree, static pressure recovery is increased by 7.8% and total pressure loss is reduced by 40.7%, which is the best among all other cases tested for VGJ. For bigger-sized VG attached to the side walls of the air-intake, static pressure recovery is increased by 5.3%, but total pressure loss is reduced by only 4.5% as compared to all other cases of VG.

    A supersonic air intake has been designed for the low speed propulsion system of the LAPCAT-MR2 aircraft. Development has been based on the XB-70 aircraft air intake which achieves extremely high performances over a wide operation range through the combined use of variable geometry and porous wall suction for boundary layer control. Design of the LAPCAT-MR2 intake has been operated through CFD simulations using DLR TAU-Code (perfect gas model - Menter SST turbulence model). First, a new boundary condition has been validated into the DLR TAU-Code (perfect gas model) for porous wall suction modelling. Standard test cases have shown surprisingly good agreement with both theoretical predictions and experimental results. Based upon this validation, XB-70 air intake performances have been assessed through CFD simulations over the subsonic, transonic and supersonic operation regions and compared to available flight data. A new simulation strategy was deployed avoiding numerical instabilities when initiating the flow in both transonic and supersonic operation modes. First, the flow must be initiated with a far field Mach number higher than the target flight Mach number. Additionally, the inlet backpressure may only be increased to its target value once the oblique shock pattern downstream the intake compression ramps is converged. Simulations using that strategy have shown excellent agreement with in-flight measurements for both total pressure recovery ratio and variable geometry schedule prediction. The demarcation between stable and unstable operation could be well reproduced. Finally, a modified version of the XB-70 air intake has been integrated in the elliptical intake on the LAPCAT vehicle. Operation of this intake in the LAPCAT-MR2 environment is under evaluation using the same simulation strategy as the one developed for the XB-70. Performances are assessed at several key operation points to assess viability of this design. This information will allow in a next

    Exhaust emissions from shipping contribute significantly to the anthropogenic burden of air pollutants such as nitrogen oxides (NOX) and particulate matter (PM). Ships emit not only when sailing on open sea, but also when approaching harbors, during port manoeuvers and at berth to produce electricity and heat for the ship's operations. This affects the population of harbor cities because long-term exposure to PM and NOX has significant effects on human health. The European Union has therefore has set air quality standards for air pollutants. Many port cities have problems meeting these standards. The port of Hamburg with around 10.000 ship calls per year is Germany's largest seaport and Europe's second largest container port. Air quality standard reporting in Hamburg has revealed problems in meeting limits for NO2 and PM10. The amount and contribution of port related ship emissions (38% for NOx and 17% for PM10) to the overall emissions in the metropolitan area in 2005 [BSU Hamburg (2012): Luftreinhalteplan für Hamburg. 1. Fortschreibung 2012] has been modelled with a bottom up approach by using statistical data of ship activities in the harbor, technical vessel information and specific emission algorithms [GAUSS (2008): Quantifizierung von gasförmigen Emissionen durch Maschinenanlagen der Seeschiffart an der deutschen Küste]. However, knowledge about the spatial distribution of the harbor ship emissions over the city area is crucial when it comes to air quality standards and policy decisions to protect human health. Hence, this model study examines the spatial distribution of harbor ship emissions (NOX, PM10) and their deposition in the Hamburg metropolitan area. The transport and chemical transformation of atmospheric pollutants is calculated with the well-established chemistry transport model TAPM (The Air Pollution Model). TAPM is a three-dimensional coupled prognostic meteorological and air pollution model with a condensed chemistry scheme including

    Oceangoing ships emit an estimated 1.2-1.6 million metric tons (Tg) of PM10 per year and represent a significant source of air pollution to coastal communities. As shown herein, ship and other emissions near the Los Angeles and Long Beach Port region strongly influence air pollution levels in the San Diego area. During time periods with regional transport, atmospheric aerosol measurements in La Jolla, California show an increase in 0.5-1 microm sized single particles with unique signatures including soot, metals (i.e., vanadium, iron, and nickel), sulfate, and nitrate. These particles are attributed to primary emissions from residual oil sourcessuch as ships and refineries, as well as traffic in the port region, and secondary processing during transport. During regional transport events, particulate matter concentrations were 2-4 times higher than typical average concentrations from local sources, indicating the health, environmental, and climate impacts from these emission sources must be taken into consideration in the San Diego region. Unless significant regulations are imposed on shipping-related activities, these emission sources will become even more important to California air quality as cars and truck emissions undergo further regulations and residual oil sources such as shipping continue to expand.

  10. Intake fraction assessment of the air pollutant exposure implications of a shift toward distributed electricity generation

    NASA Astrophysics Data System (ADS)

    Heath, Garvin A.; Granvold, Patrick W.; Hoats, Abigail S.; W Nazaroff, William

    Small-scale, distributed electricity generation (DG) technologies have been promoted for their many benefits as compared to the traditional paradigm of large, centralized power plants. To evaluate the implications for human inhalation exposure resulting from a shift toward DG, we combined Gaussian plume modeling and a GIS-based inhalation exposure assessment of existing and hypothetical power-generation facilities in California. Twenty-five existing central stations (CSs) were analyzed and compared with hypothetical DG technologies deployed in the downtown areas of the 11 most populous cities in California. The intake fraction (iF) for primary pollutants was computed for populations living within 100 km of each source, using meteorological conditions typical of the long-term observational record and population, lifetime-average breathing rates. The iF (a dimensionless term representing the proportion of pollutant mass emitted by a source that is eventually inhaled) concisely expresses the source-to-intake relationship, is independent of the emissions characteristics of the plants assessed, and normalizes for the large scale differences between the two paradigms of electricity generation. The median iF for nonreactive primary pollutants emitted from the 25 CSs is 0.8 per million compared to 16 per million for the 11 DG units. The difference is partly attributable to the closer proximity of DG sources to densely populated areas as compared to typical CS facilities. In addition, the short stacks of DG sources emphasize near-source population exposure more than traditional CSs, and increase exposures during periods of low wind speed, low mixing height and stable atmospheric conditions. Strategies that could reduce the potential increase in air pollutant intake from DG include maximally utilizing waste heat in combined heat and power operations, increasing the release height of DG effluents and deploying DG technologies that do not emit air pollutants.

    This work is intended to assess the impact on local air quality due to atmospheric emissions from port area activities for a new port in project in the Mediterranean Sea. The sources of air pollutants in the harbour area are auxiliary engines used by ships at berth during loading/offloading operations. A fleet activity-based methodology is first applied to evaluate annual pollutant emissions (NO(X), SO(X), PM, CO and VOC) based on vessel traffic data, ships tonnage and in-port hotelling time for loading/offloading operations. The 3-dimensional Calpuff transport and dispersion model is then applied for the subsequent assessment of the ground level spatial distribution of atmospheric pollutants for both long-term and short-term averaging times. Compliance with current air quality standards in the port area is finally evaluated and indications for port operation are provided. Some methodological aspects of the impact assessment procedure, namely those concerning the steps of emission scenario definitions and model simulations set-up at the project stage, are specifically addressed, suggesting a pragmatic approach for similar evaluations for small new ports in project.

    The air intake shaft (AS) was geologically mapped from the surface to the Waste Isolation Pilot Plant (WIPP) facility horizon. The entire shaft section including the Mescalero Caliche, Gatuna Formation, Santa Rosa Formation, Dewey Lake Redbeds, Rustler Formation, and Salado Formation was geologically described. The air intake shaft (AS) at the Waste Isolation Pilot Plant (WIPP) site was constructed to provide a pathway for fresh air into the underground repository and maintain the desired pressure balances for proper underground ventilation. It was up-reamed to minimize construction-related damage to the wall rock. The upper portion of the shaft was lined with slip-formed concrete, while the lower part of the shaft, from approximately 903 ft below top of concrete at the surface, was unlined. As part of WIPP site characterization activities, the AS was geologically mapped. The shaft construction method, up-reaming, created a nearly ideal surface for geologic description. Small-scale textures usually best seen on slabbed core were easily distinguished on the shaft wall, while larger scale textures not generally revealed in core were well displayed. During the mapping, newly recognized textures were interpreted in order to refine depositional and post-depositional models of the units mapped. The objectives of the geologic mapping were to: (1) provide confirmation and documentation of strata overlying the WIPP facility horizon; (2) provide detailed information of the geologic conditions in strata critical to repository sealing and operations; (3) provide technical basis for field adjustments and modification of key and aquifer seal design, based upon the observed geology; (4) provide geological data for the selection of instrument borehole locations; (5) and characterize the geology at geomechanical instrument locations to assist in data interpretation. 40 refs., 27 figs., 1 tab.

  13. Measuring OutdoorAir Intake Rates Using Electronic Velocity Sensors at Louvers and Downstream of Airflow Straighteners

    2008-10-01

    Practical and accurate technologies are needed for continuously measuring and controlling outdoor air (OA) intake rates in commercial building heating, ventilating, and air conditioning (HVAC) systems. This project evaluated two new measurement approaches. Laboratory experiments determined that OA flow rates were measurable with errors generally less than 10percent using electronic air velocity probes installed between OA intake louver blades or at the outlet face of louvers. High accuracy was maintained with OA flow rates as low as 15percent of the maximum for the louvers. Thus, with this measurement approach HVAC systems do not need separate OA intakes for minimum OA supply. System calibration parameters are required for each unique combination of louver type and velocity sensor location but calibrations are not necessary for each system installation. The research also determined that the accuracy of measuring OA flow rates with velocity probes located in the duct downstream of the intake louver was not improved by installing honeycomb airflow straighteners upstream of the probes. Errors varied with type of upstream louver, were as high as 100percent, and were often greater than 25percent. In conclusion, use of electronic air velocity probes between the blades of OA intake louvers or at the outlet face of louvers is a highly promising means of accurately measuring rates of OA flow into HVAC systems. The use of electronic velocity probes downstream of airflow straighteners is less promising, at least with the relatively small OA HVAC inlet systems employed in this research.

    1. The relation of V̇O2 and speed was measured on seven athletes running on a cinder track and an all-weather track. The results were compared with similar observations on four athletes running on a treadmill. 2. In treadmill running the relation was linear and the zero intercept coincided with resting V̇O2. 3. In track running the relation was curvilinear, but was adequately represented by a linear regression over a range of speeds extending from 8·0 km/hr (2·2 m/sec) to 21·5 km/hr (6·0 m/sec). The slope of this line was substantially steeper than the regression line slope for treadmill running. 4. The influence of air resistance in running was estimated from measurements of V̇O2 on a subject running on a treadmill at constant speed against wind of varying velocity. 5. The extra O2 intake (ΔV̇O2) associated with wind increased as the square of wind velocity. If wind velocity and running velocity are equal, as in running on a track in calm air, ΔV̇O2 will increase as the cube of velocity. 6. It was estimated that the energy cost of overcoming air resistance in track running is about 8% of total energy cost at 21·5 km/hr (5000 m races) and 16% for sprinting 100 m in 10·0 sec.

    1992-01-01

    A brief review of the work accomplished by the numerical subgroup of AGARD Working Group 13 on the aerodynamics of high speed air intakes is presented. This work comprised the selection of test cases for which experimental data were available. The test cases were chosen to range in complexity from normal-shock/boundary-layer interaction to full forebody-inlet combinations. Computations for these test cases were solicited from a large number of organizations and individual researchers within the NATO countries. The computation methods reached from Euler solvers (with and without boundary layer corrections) to full Reynolds averaged Navier-Stokes codes. The group compared these results with the test data available for each test case. A short overview of the CFD methods employed, a description of the test cases selected, and some of the comparisons between CFD solutions and test data are presented. The conclusions and recommendations drawn from this assessment are given.

    Improve the quality of the air is one of the most important challenges we are facing especially in urban area. The open hardware paradigm can promote the positive connection of institution and scientific community with citizen. The goal of this work is to describe how a well-known pollution sensing technology, such as the electrochemical one, may be adopted in an open hardware paradigm in order to realize a ground level ozone sensor station. Our approach is to use this type of sensors to complement and empower traditional measuring networks in order to provide a better support to the models and to the identification of the pollution sources. The calibration methodology is based on the online coupling of new sensor measurements and observations of official network. Several linear calibration and a linear error correction algorithm based on temperature are performed and evaluated. The new air quality station allows to increase the frequency of sampling up to minutes and, due to the low cost, can stimulate the utilization by no-professionals. We test the air quality station in portal area and compare the results with traditional observations.

    The cost-effective mitigation of adverse health effects caused by air pollution requires information on the contribution of different emission sources to exposure. In urban areas the exposure potential of different sources may vary significantly depending on emission height, population density, and other factors. In this study, we quantified this intraurban variability by predicting intake fraction (iF) for 3,066 emission sources in Warsaw, Poland. iF describes the fraction of the pollutant that is inhaled by people in the study area. We considered the following seven pollutants: particulate matter (PM), nitrogen oxides (NOx), sulfur dioxide (SO2), benzo[a] pyrene (BaP), nickel (Ni), cadmium (Cd), and lead (Pb). Emissions for these pollutants were grouped into four emission source categories (Mobile, Area, High Point, and Other Point sources). The dispersion of the pollutants was predicted with the CALPUFF dispersion model using the year 2005 emission rate data and meteorological records. The resulting annual average concentrations were combined with population data to predict the contribution of each individual source to population exposure. The iFs for different pollutant-source category combinations varied between 51 per million (PM from Mobile sources) and 0.013 per million (sulfate PM from High Point sources). The intraurban iF variability for Mobile sources primary PM emission was from 4 per million to 100 per million with the emission-weighted iF of 44 per million. These results propose that exposure due to intraurban air pollution emissions could be decreased more effectively by specifically targeting sources with high exposure potency rather than all sources.

    Vehicular air pollutant emissions are characterized by a high degree of spatial variability that is correlated with the distribution of people. The consequences of the spatial association between emissions and exposed populations have not been fully captured in lifecycle and other impact assessments. The intake fraction (iF) quantifies aggregate air-pollutant exposures attributable to sources. Utilizing source-receptor (S-R) relationships derived from the US Environmental Protection Agency's AERMOD steady-state plume model, we quantify the intake fraction of conserved pollutants emitted from on-road mobile sources and report here the first characterization across approximately 65,000 census tracts of the conterminous United States. Considering exposures out to 50 km from the source, the population-weighted mean iF is 8.6 parts per million (ppm). The population-weighted median generally increases with geographic scale, from 3.6 ppm for census tracts to 4.2 ppm for counties, and 5.1 ppm for states, while the population-weighted interquartile range (IQR) progressively narrows as geographic scale increases: 0.85-8.8 ppm for census tracts, 1.5-8.5 ppm for counties, and 3.2-7.5 ppm for states. Across the four US Census regions, the population weighted median iF varies from 2.2 ppm (South) to 7.5 ppm (West), and the census-tract IQR spans an order of magnitude in each region (2.1-17 ppm in the West; 0.55-6.9 ppm in the Midwest; 0.45-5.5 ppm in the South; and 1.8-18 ppm in the Northeast). The population-weighted mean intake fraction for populous urban counties is about two orders of magnitude greater than for sparsely populated rural counties. On a population-weighted average basis and considering the 50 km analysis range, 75% of the intake occurs in the same county as emissions.

    An increase of the passenger ships traffic is expected in the Mediterranean Sea as targeted by the EU Blue Growth initiative. This increase is expected to impact the Mediterranean port-cities air quality considering not only the conventional atmospheric pollutants but also the toxic ones that are emitted by the ships (e.g. Nickel). The aim of this study is the estimation of the present and future time pollutant emissions from cruise and passenger maritime transport in the port area of Thessaloniki (Greece) as well as the impact of those emissions on the city air quality. Cruise and passenger ship emissions have been estimated for the year 2013 over a 100m spatial resolution grid which covers the greater port area of Thessaloniki. Emissions have been estimated for the following macro-pollutants; NOx, SO2, NMVOC, CO, CO2 and particulate matter (PM). In addition, the most important micro-pollutants studied in this work are As, Cd, Pb, Ni and Benzo(a)pyrene for which air quality limits have been set by the EU. Emissions have been estimated for three operation modes; cruising, maneuvering and hotelling. For the calculation of the present time maritime emissions, the activity data used were provided by the Thessaloniki Port Authority S.A. Moreover, future pollutant emissions are estimated using the future activity data provided by the Port Authority and the IMO legislation for shipping in the future. In addition, two mitigation emission scenarios are examined; the use of Liquefied Natural Gas (LNG) as a fuel used by ships and the implementation of cold ironing which is the electrification of ships during hotelling mode leading to the elimination of the corresponding emissions. The impact of the present and future passenger ship emissions on the air quality of Thessaloniki is examined with the use of the model CALPUFF applied over the 100m spatial resolution grid using the meteorology of WRF. Simulations of the modeling system are performed for four different emission

    For the purpose of contributing to global environment protection, several research studies have been conducted involving clean-burning diesel engines. In recent diesel engines with Exhaust Gas Recirculation (EGR) systems and a Variable Nozzle Turbocharger (VNT), mutual interference between EGR and VNT has been noted. Hence, designing and adjusting control of the conventional PID controller is particularly difficult at the transient state in which the engine speed and fuel injection rate change. In this paper, we formulate 1st principal model of air intake system of diesel engines and transform it to control oriented model including an engine steady state model and a transient model. And we propose a model-based control system with the LQR Controller, Saturation Compensator, the Dynamic Feed-forward and Disturbance Observer using a transient model. Using this method, we achieved precise reference tracking and emission reduction in transient mode test with the real engine evaluations.

    This patent describes an air-cooled overhead-valve internal combustion engine. The engine is composed of a crankcase with a crankshaft, a cylinder block with a cylinder head and a combustion chamber mounted in the crankcase. At least a pair of intake and exhaust valves installed in intake and exhaust ports are formed in the cylinder head. A valve drive system mounted adjacent to the cylinder block drives the intake and exhaust valves through cam-driven push rods. An intake pipe is connected at one end of the intake port and at its opposite end to an air cleaner and a carburetor. An exhaust duct is connected at one end of the exhaust port. A flywheel is joined to the crankshaft at the other end of the output side end of the crankshaft and a cooling fan mounted on the flywheel. The improvements are where the cooling fan is housed, together with the crankcase and flywheel, in a fan casing having a pair of inlet and outlet openings bored in opposite walls. The inlet opening is located at the flywheel side of the crankshaft, while the outlet opening is located at the opposite side of the crankshaft from the flywheel. The cam-driven push rods are located in the crankcase on that side of the cylinder block far remote from where the intake pipe is connected to the intake port. The cooling fan is mounted in the fan casing in such a manner that the cooling air from the cooling fan is allowed to flow in a direction substantially parallel with the axis of the crankshaft, along the surface of the cylinder block and cylinder head.

    traffic changes as foreseen for the year 2020 by the Port Authority Investment Plan and by the reduction of the sulfur content in fuels used by ships in cruising mode to 0.5% m/m according to a revision of the MARPOL Annex VI. Based on the above, an approximately 60% increase in the future maritime sector PM10 emissions is expected due to the high increase of the traffic of vessels. The impact of future emissions on the air quality of Thessaloniki is examined with the use of the modelling system WRF-CAMx applied with 2km spatial resolution over the study area. Simulations of the modelling system are performed for a summertime (July 2011) and a wintertime (15 November to 15 December 2011) period accounting for present time (scenario A) and future time (scenario B) pollutant emissions. The differences in pollutant levels (mainly PM) between the scenarios examined are presented and discussed.

  13. Experimental Studies on Unsteady Start/Unstart of High Speed Air Intakes with Moving Cowl

    NASA Astrophysics Data System (ADS)

    Senthilkumar, P.; Muruganandam, T. M.

    Inlet plays a major role in the performance of scramjet engines. It should be designed to deliver required quantity of air at supersonic speed to the combustion chamber. When the back pressure is increased in a scramjet inlet, it will make the inlet unstart. It may lead to severe shock oscillations, pressure fluctuations, thrust loss and even combustor flame out. There could be some ways to restart the inlet at the same back pressure in order to save the engine from complete failure. An attempt is made in this research to study the influence of the continuous movement of cowl to start the inlet during the flow. The inlet is forced to unstart by back pressure rise. Then the inlet is started by cowl movement at the same back pressure. This is done by moving the cowl continuously. The flow field is captured by high speed camera. The unstart, transition and start processes are studied from high speed Schlieren images. Then the cowl is returned back to determine any hysteresis present.

  15. Atmospherically-induced water oscillations detected in the port of Quequén, Buenos Aires, Argentina

    NASA Astrophysics Data System (ADS)

    Dragani, Walter C.; D'Onofrio, Enrique E.; Grismeyer, Walter; Fiore, Monica M. E.; Campos, María Inés

    Sea level data gathered at Quequén, corresponding to the four most energetic events detected in 1982, are analyzed and compared with simultaneous sea level data recorded at Mar del Plata, Pinamar and Mar de Ajó. Large-amplitude sea-level oscillations at these locations are generally superposed to low-amplitude oscillations (“background”) which are one or two order of magnitude lower than the first ones. Background at Quequén is characterized by a broadband energy spectrum with maximum energy around 17-35 min. During energetic events at Quequén, the spectral peaks are situated between 0.8 and 4.0 cph (15-75 min) and wavelet analysis shows intermittent activity of large-amplitude waves (they show up irregularly during short lapses of 100-200 min long, approximately). The computed ratios between sea level variances of the active event and the preceding background at Quequén, Mar de Ajó, Pinamar and Mar del Plata apparently do not have a relationship among locations nor events. Such noticeable variability in the spectral peak positions, variances and ratios could likely be related to the celerity, amplitude, direction and period of atmospheric gravity waves in the region. Large-amplitude sea-level oscillations are always firstly observed at Quequén and, subsequently further north, at Mar del Plata, Pinamar and Mar de Ajó, respectively. Maximum amplitudes detected for each event at these different locations are very similar. These results support that atmospherically-induced large-amplitude sea-level oscillations (generated on the continental shelf) would enter the port of Quequén through its narrow mouth while they propagate towards Mar del Plata, Pinamar and Mar de Ajó, where they show up in tidal records some hours later.

    1963-02-12

    This invention provides a simple pressure-actuated closure whereby windowless observation ports are opened to the atmosphere at preselected altitudes. The closure comprises a disk which seals a windowless observation port in rocket hull. An evacuated instrument compartment is affixed to the rocket hull adjacent the inner surface of the disk, while the outer disk surface is exposed to the atmosphere through which the rocket is traveling. The pressure differential between the evacuated instrument compartment and the relatively high pressure external atmosphere forces the disk against the edge of the observation port, thereby effecting a tight seai. The instrument compartment is evacuated to a pressure equal to the atmospheric pressure existing at the altitude at which it is desiretl that the closure should open. When the rocket reaches this preselected altitude, the inwardly directed atmospheric force on the disk is just equaled by the residual air pressure force within the instrument compartment. Consequently, the closure disk falls away and uncovers the open observation port. The separation of the disk from the rocket hull actuates a switch which energizes the mechanism of a detecting instrument disposed within the instrument compartment. (AE C)

  1. Near-road air pollution impacts of goods movement in communities adjacent to the Ports of Los Angeles and Long Beach

    NASA Astrophysics Data System (ADS)

    Kozawa, Kathleen H.; Fruin, Scott A.; Winer, Arthur M.

    A mobile platform was outfitted with real-time instruments to spatially characterize pollution concentrations in communities adjacent to the Ports of Los Angeles and Long Beach, communities heavily impacted by emissions related to dieselized goods movement, with the highest localized air pollution impacts due to heavy-duty diesel trucks (HDDT). Measurements were conducted in the winter and summer of 2007 on fixed routes driven both morning and afternoon. Diesel-related pollutant concentrations such as black carbon, nitric oxide, ultrafine particles, and particle-bound polycyclic aromatic hydrocarbons were frequently elevated two to five times within 150 m downwind of freeways (compared to more than 150 m) and up to two times within 150 m downwind of arterial roads with significant amounts of diesel traffic. While wind direction was the dominant factor associated with downwind impacts, steady and consistent wind direction was not required to produce; high impacts were observed when a given area was downwind of a major roadway for any significant fraction of time. This suggests elevated pollution impacts downwind of freeways and of busy arterials are continuously occurring on one side of the road or the other, depending on wind direction. The diesel truck traffic in the area studied was high, with more than 2000 trucks per peak hour on the freeway and two- to six-hundred trucks per hour on the arterial roads studied. These results suggest that similarly-frequent impacts occur throughout urban areas in rough proportion to diesel truck traffic fractions. Thus, persons living or working near and downwind of busy roadways can have several-fold higher exposures to diesel vehicle-related pollution than would be predicted by ambient measurements in non-impacted locations.

    The San Diego/Tijuana US-Mexico border crossing at the San Ysidro Port of Entry (POE) is the world's busiest international land border crossing (GSA, 2013). San Ysidro, California, is the US community immediately adjacent to the border crossing. More than 90% of San Ysidro residents are Hispanic, and the average household income is less than 60% of the San Diego regional average. This study investigated the San Ysidro POE as a source of traffic-related air pollutants in San Ysidro, especially in relation to wind direction and northbound vehicle wait times. The pollutants ultrafine particulate matter (UFP), black carbon (BC), and particulate matter <2.5 μm in diameter (PM2.5) were periodically sampled through the course of 2010 at four rooftop locations: one commercial establishment near the POE, two elementary schools in San Ysidro, and a coastal estuary reference site. Weather data from two nearby sites and northbound border wait times were also collected. Results indicate consistently higher daytime BC and UFP concentrations at the measurement sites near the POE. Pollution concentrations were higher during low wind speeds or when wind was blowing from the POE towards San Ysidro. In February, March and November measurements, black carbon pollution appeared to be significantly positively associated with the POE northbound wait times when the wind direction was blowing from the POE towards San Ysidro or during low wind speeds, but not when the wind direction was from the west/northwest towards the POE. This pilot study is the first to investigate the potential effect of the POE, especially the long northbound traffic delays, on the nearby community of San Ysidro. Disparities in traffic exposures are an environmental justice issue and this should be taken into account during planning and operation of POEs.

    To obtain a comprehensive understanding of the main source and route of human exposure to polybrominated diphenyl ethers (PBDEs), the daily intake and uptakes through inhalation, ingestion, and dermal contact for Shanghai residents were estimated on the basis of the PBDE concentrations in the air obtained in the present study and previous data reported in the literature. The PBDE concentrations in the gas and particle phases collected in Shanghai were 0.99-57.5 and 0.1-234 pg/m(3), respectively. The contamination levels of PBDEs in the air in Shanghai were similar to or slightly lower than the data from other regions. The estimated total daily intakes of PBDEs through the three routes were 607 and 1,636 ng/day for children and adults, respectively, while they decreased to 63.0 and 93.1 ng/day when the uptake efficiency (which is the fraction of contaminants that reaches the systemic circulation) of PBDEs was added to calculation. The results showed that dust is the main source of human exposure to PBDEs when PBDE uptake efficiency was not considered. It accounted for 66.2-79.2 % of the total PBDE intake. However, food is the main source, which accounted for 66.6-75.1 %, when the uptake efficiency was added to calculation. Among the three routes, dermal contact (53.1-76.6 %) is the main pathway, whereas ingestion (84.7-92.9 %) is the main one when the uptake efficiency was considered. Furthermore, risk assessment showed that the PBDE exposure amount would not cause obvious non-cancer and cancer risks to local residents. PMID:25009095

    The Waste Receiving and Processing Module I (WRAP-1) facility must have the ability to allow 55-gallon drums to enter and exit glovebox enclosures. An Entry/Exit Port (Appendix 1, Figure 1), designed by United Engineers and Constructors (UE&C), is one method chosen for drum transfer. The Entry/Exit Port is to be used for entry of 55-gallon drums into both process entry gloveboxes, exit of 55-gallon drum waste pucks from the low-level waste (LLW) glovebox, and loadout of waste from the restricted waste management glovebox. The Entry/Exit Port relies on capture velocity air flow and a neoprene seal to provide alpha confinement when the Port is in the open and closed positions, respectively. Since the glovebox is in a slight vacuum, air flow is directed into the glovebox through the space between the overpack drum and glovebox floor. The air flow is to direct any airborne contamination into the glovebox. A neoprene seal is used to seal the Port door to the glovebox floor, thus maintaining confinement in the closed position. Entry/Exit Port testing took place February 17, 1993, through April 14, 1993, in the 305 building of Westinghouse Hanford Company. Testing was performed in accordance with the Entry/Exit Port Testing Test Plan, document number WHC-SD-WO26-TP-005. A prototype Entry/Exit Port built at the Hanford Site was tested using fluorescent paint pigment and smoke candles as simulant contaminants. This test report is an interim test report. Further developmental testing is required to test modifications made to the Port as the original design of the Port did not provide complete confinement during all stages of operation.

    A multi-port valve is described for regulating, as a function of ambient air having varying wind velocity and wind direction in an open-field control area, the distribution of a fluid, particularly carbon dioxide (CO{sub 2}) gas, in a fluid distribution system so that the control area remains generally at an elevated fluid concentration or level of said fluid. The multi-port valve generally includes a multi-port housing having a plurality of outlets there through disposed in a first pattern of outlets and at least one second pattern of outlets, and a movable plate having a plurality of apertures extending there through disposed in a first pattern of apertures and at least one second pattern of apertures. The first pattern of apertures being alignable with the first pattern of outlets and the at least one second pattern of apertures being alignable with the second pattern of outlets. The first pattern of apertures has a predetermined orientation with the at least one second pattern of apertures. For an open-field control area subject to ambient wind having a low velocity from any direction, the movable plate is positioned to equally distribute the supply of fluid in a fluid distribution system to the open-field control area. For an open-field control area subject to ambient wind having a high velocity from a given direction, the movable plate is positioned to generally distribute a supply of fluid in a fluid distribution system to that portion of the open-field control area located upwind. 7 figs.

  9. Compressor ported shroud for foil bearing cooling

    DOEpatents

    Elpern, David G.; McCabe, Niall; Gee, Mark

    2011-08-02

    A compressor ported shroud takes compressed air from the shroud of the compressor before it is completely compressed and delivers it to foil bearings. The compressed air has a lower pressure and temperature than compressed outlet air. The lower temperature of the air means that less air needs to be bled off from the compressor to cool the foil bearings. This increases the overall system efficiency due to the reduced mass flow requirements of the lower temperature air. By taking the air at a lower pressure, less work is lost compressing the bearing cooling air.

  10. Indirect exposure screening model for evaluating contaminant intake from air emissions via ingestion of milk and beef: Risk-based air concentrations

    SciTech Connect

    Chew, C.M.; Lorenzana, R.M.; Garry, M.

    1997-09-01

    A conceptual model has been developed to estimate screening level, risk-based contaminant air concentrations with respect to human health risks from indirect exposures to air emission. The model can evaluate risks from products of incomplete combustion, principal organic hazardous constituents associated with hazardous waste incinerator emissions and other air emittants. Derivation of screening levels is facilitated with a computer spreadsheet requiring six input values. To avoid complex air modeling, estimates are used for some parameters, such as particle deposition rate. The risk-based air concentrations can be used in the early stages of a risk investigation (prior to the trial burn at some incinerator sites) for screening purposes. These risk-based air concentrations can be compared to air concentrations extrapolated from trial burn or other relevant site historical data to determine whether or not a significant risk due to indirect exposures may be present. If screening comparisons reveal the possibility of significant risks, a more extensive risk assessment analysis can be performed and risk-drivers can be identified early in the process. Conversely, if significant risk is clearly not present for contaminants of concern, the analysis can be concluded cost-effectively with the screening process.

    Data are presented from the Air Intake Shaft Test, an in situ test fielded at the Waste Isolation Pilot Plant (WIPP). The construction of this shaft, well after the initial three access shafts, presented an unusual opportunity to obtain valuable detailed data on the mechanical response of a shaft for application to seal design. These data include selected fielding information, test configuration, instrumentation activities, and comprehensive results from a large number of gages. Construction of the test began in December 1987; gage data in this report cover the period from May 1988 through July 1995, with the bulk of the data obtained after obtaining access in November, 1989 and from the heavily instrumented period after remote gage installation between May, 1990, and October, 1991.

The historical record is replete with accounts from ship captains and harbour masters describing their fateful encounters with currents and surges caused by these destructive waves. Despite the well-known hazard, only since the trans-oceanic tsunamis of the early twenty-first century (2004, 2010 and 2011) have coastal and port engineering practitioners begun to develop port-specific warning and response products that accurately assess the effects of tsunami-induced currents in addition to overland flooding and inundation. The hazard from strong currents induced by far-field tsunami remains an underappreciated risk in the port and maritime community. In this paper, we will discuss the history of tsunami current observations in ports, look into the current state of the art in port tsunami hazard assessment and discuss future research trends.

  16. Self-regulating fuel staging port for turbine combustor

    DOEpatents

    Van Nieuwenhuizen, William F.; Fox, Timothy A.; Williams, Steven

    2014-07-08

    A port (60) for axially staging fuel and air into a combustion gas flow path 28 of a turbine combustor (10A). A port enclosure (63) forms an air path through a combustor wall (30). Fuel injectors (64) in the enclosure provide convergent fuel streams (72) that oppose each other, thus converting velocity pressure to static pressure. This forms a flow stagnation zone (74) that acts as a valve on airflow (40, 41) through the port, in which the air outflow (41) is inversely proportion to the fuel flow (25). The fuel flow rate is controlled (65) in proportion to engine load. At high loads, more fuel and less air flow through the port, making more air available to the premixing assemblies (36).

    Single port thoracic surgery, reduced port surgery and needlescopic surgery attract attention as one of the minimally invasive surgery in thoracic surgery recently. Single port thoracic surgery was advocated by Rocco in 2004, it was reported usefulness of single port thoracic surgery for primary spontaneous pneumothorax. The surgical procedure as single (or reduced) port thoracic surgery is roughly divided into the following. One is operated with instruments inserted from the single extended incision, and the other is operated with instruments punctured without extending incision. It is not generally complicated procedures in single port thoracic surgery. Primary spontaneous pneumothorax and biopsy for lung and pleura are considered the surgical indication for single (or reduced) port surgery. It is revealed that single port surgery for primary spontaneous pneumothorax is less invasive than conventional surgery. Single port and reduced port thoracic surgery will spread furthermore in the future. PMID:27440029

    2009-04-01

    The Port Operational Marine Observing System (POMOS) is a network of distributed sensors and centralized data collecting, processing and distributing unit. The system is designed to allow for the real-time assessment of weather and marine conditions throughout the major Bulgarian ports: Varna, Burgas and Balchik, supporting thereby Maritime administration to secure safety navigation in bays, canals and ports. Real-time information within harbors is obtained using various sensors placed at thirteen strategic locations to monitor the current state of the environment. The most important for navigation weather and sea-state parameters are measured: wind speed and direction, air temperature, relative humidity, atmospheric pressure, visibility, solar radiation, water temperature and salinity, sea level, currents speed and direction, mean wave's parameters. The system consist of: 11 weather stations (3 with extra solar radiation and 4 with extra visibility measurement), 9 water temperature and salinity sensors, 9 sea-level stations, two sea currents and waves stations and two canal currents stations. All sensors are connected to communication system which provides direct intranet access to the instruments. Every 15 minutes measured data is transmitted in real-time to the central collecting system, where data is collected, processed and stored in database. Database is triple secured to prevent data losses. Data collection system is double secured. Measuring system is secured against short power failure and instability. Special software is designed to collect, store, process and present environmental data and information on different user-friendly screens. Access to data and information is through internet/intranet with the help of browsers. Actual data from all measurements or from separate measuring place can be displayed on the computer screens as well as data for the last 24 hours. Historical data are available using report server for extracting data for selectable

    1978-08-22

    A multiple-port valve assembly is designed to direct flow from a primary conduit into any one of a plurality of secondary conduits as well as to direct a reverse flow. The valve includes two mating hemispherical sockets that rotatably receive a spherical valve plug. The valve plug is attached to the primary conduit and includes diverging passageways from that conduit to a plurality of ports. Each of the ports is alignable wih one or more of a plurality of secondary conduits fitted into one of the hemispherical sockets. The other hemispherical socket includes a slot for the primary conduit such that the conduit's motion along that slot with rotation of the spherical plug about various axes will position the valve-plug ports in respect to the secondary conduits.

  19. Use of proton-transfer-reaction mass spectrometry to characterize volatile organic compound sources at the La Porte super site during the Texas Air Quality Study 2000

    2003-08-01

    Proton-transfer-reaction mass spectrometry (PTR-MS) was deployed for continuous real-time monitoring of volatile organic compounds (VOCs) at a site near the Houston Ship Channel during the Texas Air Quality Study 2000. Overall, 28 ions dominated the PTR-MS mass spectra and were assigned as anthropogenic aromatics (e.g., benzene, toluene, xylenes) and hydrocarbons (propene, isoprene), oxygenated compounds (e.g., formaldehyde, acetaldehyde, acetone, methanol, C7 carbonyls), and three nitrogen-containing compounds (e.g., HCN, acetonitrile and acrylonitrile). Biogenic VOCs were minor components at this site. Propene was the most abundant lightweight hydrocarbon detected by this technique with concentrations up to 100+ nmol mol-1, and was highly correlated with its oxidation products, formaldehyde (up to ˜40 nmol mol-1) and acetaldehyde (up to ˜80 nmol/mol), with typical ratios close to 1 in propene-dominated plumes. In the case of aromatic species the high time resolution of the obtained data set helped in identifying different anthropogenic sources (e.g., industrial from urban emissions) and testing current emission inventories. A comparison with results from complimentary techniques (gas chromatography, differential optical absorption spectroscopy) was used to assess the selectivity of this on-line technique in a complex urban and industrial VOC matrix and give an interpretation of mass scans obtained by "soft" chemical ionization using proton-transfer via H3O+. The method was especially valuable in monitoring rapidly changing VOC plumes which passed over the site, and when coupled with meteorological data it was possible to identify likely sources.

    2012-01-01

    Carbohydrates represent more than 50% of the energy sources present in most human diets. Sugar intake is regulated by metabolic, neuronal, and hedonic factors, and gene polymorphisms are involved in determining sugar preference. Nutrigenomic adaptations to carbohydrate availability have been evidenced in metabolic diseases, in the persistence of lactose digestion, and in amylase gene copy number. Furthermore, dietary oligosaccharides, fermentable by gut flora, can modulate the microbiotal diversity to the benefit of the host. Genetic diseases linked to mutations in the disaccharidase genes (sucrase-isomaltase, lactase) and in sugar transporter genes (sodium/glucose cotransporter 1, glucose transporters 1 and 2) severely impact carbohydrate intake. These diseases are revealed upon exposure to food containing the offending sugar, and withdrawal of this sugar from the diet prevents disease symptoms, failure to thrive, and premature death. Tailoring the sugar composition of diets to optimize wellness and to prevent the chronic occurrence of metabolic diseases is a future goal that may yet be realized through continued development of nutrigenetics and nutrigenomics approaches.

    1980-01-01

    The listings, user's instructions, sample inputs, and sample outputs of two computer programs which are especially useful in obtaining an approximate solution of the viscous flow over an arbitrary nonlifting three dimensional body are provided. The first program performs a potential flow solution by a well known panel method and readjusts this initial solution to account for the effects of the boundary layer displacement thickness, a nonuniform but unidirectional onset flow field, and the presence of air intakes and exhausts. The second program is effectually a geometry package which allows the user to change or refine the shape of a body to satisfy particular needs without a significant amount of human intervention. An effort to reduce the cruise drag of light aircraft through an analytical study of the contributions to the drag arising from the engine cowl shape and the foward fuselage area and also that resulting from the cooling air mass flowing through intake and exhaust sites on the nacelle is presented. The programs may be effectively used to determine the appropriate body modifications or flow port locations to reduce the cruise drag as well as to provide sufficient air flow for cooling the engine.

    Port and Harbor Security is a daunting task to which optics and photonics offers significant solutions. We are pleased to report that the 2005 Defense and Security Symposium (DSS, Orlando, FL) will include reports on active and passive photonic systems operating from both airborne and subsurface platforms. In addition to imaging techniques, there are various photonic applications, such as total internal reflection fluorescence (TIRF), which can be used to ''sniff'' for traces of explosives or contaminants in marine. These non-imaging technologies are beyond the scope of this article, but will also be represented at DSS 2005. We encourage colleagues to join our technical group to help us to make our ports and harbors safer and more secure.

    The capacity through the use of robots with on board visual, NBC and HAZMAT sensors to rapidly and continuously screen convoys and staged exposed assets would be a force multiplier and measurably improve base and force protection at both inbound and outbound DOD and commercial facilities. This paper chronicles our experiment with the ODIS robot at the Ports of Los Angeles (POLA) and Long Beach (POLB) in July of 2003. POLA & POLB are responsible for moving over 30% of the United States trade goods. Queues of 54" container trucks routinely exceed 100 trucks, extending for over a mile from the port entrances. Spotted equipment and convoys at staging areas are a high visibility and value assets to a terrorist incident. The POLA/POLB scenario is also representative of TRANSCOM operations at the port of Basra during current operation in Iraq. The California Highway Patrol is responsible for physically inspecting these vehicles for roadworthiness and contraband, a dangerous and dirty job. We will also discuss the use of ODIS robots for this task.

  17. ITER Port Interspace Pressure Calculations

    SciTech Connect

    Carbajo, Juan J; Van Hove, Walter A

    2016-01-01

    The ITER Vacuum Vessel (VV) is equipped with 54 access ports. Each of these ports has an opening in the bioshield that communicates with a dedicated port cell. During Tokamak operation, the bioshield opening must be closed with a concrete plug to shield the radiation coming from the plasma. This port plug separates the port cell into a Port Interspace (between VV closure lid and Port Plug) on the inner side and the Port Cell on the outer side. This paper presents calculations of pressures and temperatures in the ITER (Ref. 1) Port Interspace after a double-ended guillotine break (DEGB) of a pipe of the Tokamak Cooling Water System (TCWS) with high temperature water. It is assumed that this DEGB occurs during the worst possible conditions, which are during water baking operation, with water at a temperature of 523 K (250 C) and at a pressure of 4.4 MPa. These conditions are more severe than during normal Tokamak operation, with the water at 398 K (125 C) and 2 MPa. Two computer codes are employed in these calculations: RELAP5-3D Version 4.2.1 (Ref. 2) to calculate the blowdown releases from the pipe break, and MELCOR, Version 1.8.6 (Ref. 3) to calculate the pressures and temperatures in the Port Interspace. A sensitivity study has been performed to optimize some flow areas.

  18. Method and apparatus for extracting water from air using a desiccant

    DOEpatents

    Spletzer, Barry L.; Callow, Diane Schafer

    2003-01-01

    The present invention provides a method and apparatus for extracting liquid water from moist air using minimal energy input. The method can be considered as four phases: (1) adsorbing water from air into a desiccant, (2) isolating the water-laden desiccant from the air source, (3) desorbing water as vapor from the desiccant into a chamber, and (4) isolating the desiccant from the chamber, and compressing the vapor in the chamber to form liquid condensate. The liquid condensate can be removed for use. Careful design of the dead volumes and pressure balances can minimize the energy required. The dried air can be exchanged for fresh moist air and the process repeated. An apparatus comprises a first chamber in fluid communication with a desiccant, and having ports to intake moist air and exhaust dried air. The apparatus also comprises a second chamber in fluid communication with the desiccant. The second chamber allows variable internal pressure, and has a port for removal of liquid condensate. Each chamber can be configured to be isolated or in communication with the desiccant. The first chamber can be configured to be isolated or in communication with a course of moist air. Various arrangements of valves, pistons, and chambers are described.

    A small air sampling system using standard air filter sampling technology has been used to monitor the air in aircraft. The device is a small ABS constructed cylinder 5 cm in diameter and 9 cm tall and can be operated by non technical individuals at an instant notice. It is completely self contained with a 4 AAA cell power supply, DC motor, a centrifugal fan, and accommodates standard 37 mm filters and backup pads. The monitor is totally enclosed and pre assembled in the laboratory. A 45 degrees twist of the cap switches on the motor and simultaneously opens up the intake ports and exhaust ports allowing air to pass through the filter. A reverse 45 degrees twist of the cap switches off the motor and closes all intake and exhaust ports, completely enclosing the filter. The whole monitor is returned to the laboratory by standard mail for analysis and reassembly for future use. The sampler has been tested for electromagnetic interference and has been approved for use in aircraft during all phases of flight. A set of samples taken by a BAe-146-300 crew member during two flights in the same aircraft and analyzed by GC-MS, indicated exposure to tricresyl phosphate (TCP) levels ranging from 31 to 83 nanograms/m(3) (detection limit <4.5 nanograms/m(3)). The latter elevated level was associated with the use of the auxiliary power unit (APU) in the aircraft. It was concluded that the air sampler was capable of monitoring air concentrations of TCP isomers in aircraft above 4.5 nanogram/m(3). PMID:18801557

  1. Four port circulator

    The circulator is a waveguide slotted bridge, at the center of which, along the axis of symmetry, is a set of toroidal ferrites arranged on a dielectric sleeve. As a result of this design, the overall dimensions of the circulator are reduced and the tuning of the circulator is simplified. An experimental model of a four port circulator was constructed in the 3-cm range of waves, with the direct losses of not over 1 dB and decouplings of not less than 19 dB in all the channels.

    Background and Objective: Robotic upper urinary tract surgery is in most of the cases performed utilizing a standard 5 port configuration. Fewer ports can potentially produce a less invasive operation. Taking in consideration the above we report a novel technique for robot assisted laparoscopic partial nephrectomy utilizing fewer ports and we test its feasibility and safety profile. Methods: Data on 11 robot-assisted laparoscopic partial nephrectomies performed by using our technique from February 2015 through June 2015 were retrospectively analyzed. The robotic platform used was DaVinci Xi (Intuitive Surgical, Inc., Sunnyvale, California, USA) with a 3-arm setup. The AirSeal system (SurgiQuest, Milford, Connecticut, USA) was used as a port allowing simultaneous introduction of 2 instruments for the bedside surgeon, obviating the need for an additional (fourth) robotic arm. A long suction-and-irrigation device and atraumatic grasping forceps were used. Both instruments were introduced through the trocar of the AirSeal system, making simultaneous introduction and use possible. We preferred the long suction-and-irrigation device, because it minimizes collision of the instruments. Results: Mean age and BMI of the patients were 55 ±14.6 y and 29.18 ± 6.85, respectively. Seven tumors were on the right side and 4 were on the left. The mean size of the tumors was 32.45 mm (± 11.31). Surgical time was 132.2 minutes (±37.17), with an estimated blood loss and ischemia time of 103.63 mL (±65.92) and 16.72 minutes (±9.52), respectively. One patient had postoperative bleeding that was resolved without transfusion. The median hospitalization period was 3.9 d (±0.53). Loss of intra-abdominal pressure was not observed, and pressure was stable at 10 mm Hg. Conclusion: The AirSeal System and its valveless trocar eliminated the need for an additional port placement in our series. The technique is feasible, safe, and reproducible; therefore, it may be implemented in selected

    Backgrounds Single-port thoracoscopic segmentectomy is a challenging option in the early stages of lung cancer. The purpose of this study was to determine the feasibility of single-port video-assisted thoracoscopic surgery (VATS) segmentectomy compared to conventional multi-port VATS. Methods A total of 45 patients underwent pulmonary segmentectomy by video-assisted thoracoscopic surgery between March 2006 and October 2015. We analyzed the operative outcomes of segmentectomy by surgical approach (34 single-port versus 11 multi-port). Results Twenty-three primary lung cancers (51.1%), 16 benign lung diseases (35.6%), and 6 secondary lung cancers (13.3%) were diagnosed and included in our study. In 29 malignancy cases (64.4%), the mean tumor size was 1.8±0.7 (range, 1–3.5) cm. Twenty patients (44.4%) underwent preoperative localization with hook-wire and radiocontrast. The most frequent operated segment was the left upper divisional segment (n=9, 30%). There was no significant difference in operation time (P=0.073), the number of dissected lymph nodes (P=0.310), intraoperative events (P=0.412), and the development of prolonged air leak (>5 days) (P=0.610) between the single-port and multi-port VATS segmentectomy groups. There was a reduction in postoperative morbidity (P<0.001) and hospital stay (P=0.029) in the single-port VATS group. Conclusions Single-port VATS segmentectomy for early lung cancer and benign lung disease, is a safe and feasible option for patients undergoing pulmonary segmentectomy. PMID:27014475

    Nakashima, K.; Saito, Tsutomu

    Intake is an important component of next generation air-breathing engines such as Ram/Scram jet engines, as well as conventional jet-propulsion systems. The supersonic intake decelerates compresses the air inflow by shocks or compression waves to appropriate flow conditions for a specific engine system. The performance of supersonic intakes is evaluated mainly by the mass flow rate and the total pressure recovery rate.

    2007-01-01

    Around the world, there is great concern about the movement of threat materials using seaport shipping containers. The benefits of early detection of weapons of mass destruction is obvious. However, the inspection process needs to be conducted in such a way as to not unreasonably impede normal commerce. Prior to actual deployment of new detection systems, policies, or procedures, it is useful to construct an operational and economic model of the port facility and to run simulations to gage the impact. Using a simulation model beforehand aids decision makers in evaluating trade-offs. PortSim was developed at ORNL by the author to allow a user to investigate a number of parameters in order to see the impact on port operations and cost. It consolidates a conceptual operations model, cost information, policy and procedures database, a real-time data acquisition capability, and information flow tracking and provides a visualization of port operations in a geospatial environment. This paper describes the use of PortSim to simulate and visualize a typical port.

    2002-01-01

    Abstract Introduction Dural port therapy (DPT) is a chiropractic procedure which can be used effectively with Sacro-Occipital Technique (SOT) procedures and which uses the sacrum as a lever to influence and balance the spine and cranium by way of the meningeal system. Discussion Rationale and research is presented to explain the basis behind DPT's method of affecting the craniospinal system and its relationship to the meninges. Though the procedure can be used with most conditions, DPT appears to be safe to use with osteoporotic conditions, fractured vertebrae, and other conditions where a “thrust” to the spine may be contraindicated. Basic methods of using DPT are presented along with alternative methods which can be applied when the basic methods are not sufficient. Conclusion DPT reduces sacral, spinal, and cranial dura meningeal tension, lesions, torque and stress, as well as dural sleeve vasomotor interference. The possibility that the doctor can influence the nervous system directly in such a powerful manner warrants further investigation. PMID:19674561

  20. Corpus Christi oil port eyed

    1993-07-05

    The Port of Corpus Christi, Texas, with the support of several oil companies and the blessing of the US Coast Guard, plans to build a $600-million deepwater harbor to accommodate supertankers. The proposed port, Safeharbor, is touted as an environmentally sound solution to current risks associated with off-loading crude oil from very large tankers at shore ports. In a system called lightering, crude now is transferred from supertankers in deep water to smaller vessels that can negotiate shallow channels. While smaller tankers need only 45 ft of water, supertankers need 80 ft. Corpus Christi has the advantage of being closer to deep water than other Gulf ports, but nevertheless, half the proposed project's cost, $300 million, would be for dredging a 10-mile channel to deep water.

  3. Multicomponent liquid and vapor fuel distribution measurements in the cylinder of a port-injected, spark- ignition engine

    NASA Astrophysics Data System (ADS)

    Styron, Joshua Putman

    Over the last twenty years, much of the innovation in automotive engine design has been directed towards meeting lower emissions standards as required by the federal government. Correlations used to tune engines that are based on engine-out hydrocarbon measurements alone often fail to be portable to other engine designs because the testing procedures provide little information on in-cylinder fuel/air mixing and combustion processes. A better understanding of in-cylinder processes should improve the applicability of emissions correlations, reducing the amount of engine testing required and providing additional emissions improvements. A 2.5 L, V-6, port-injected engine was modified for optical access by separating one head from the block. The engine could be fitted with one of two heads that produced either a swirling flow or a tumbling flow in the engine. An extended piston with a window in its crown rides in a transparent cylinder liner of fused silica. This arrangement is suitable for laser imaging techniques. Planar laser-induced exciplex fluorescence, which allows the simultaneous, but separate, imaging of liquid and vapor fuel, was extended to capture components of different volatilities in a model fuel designed to simulate the distillation curve of a typical gasoline. Accurate representation of both phases and more than one volatility was demonstrated to be necessary for drawing complete conclusions from fuel distribution data. The exciplex fluorescence technique was calibrated in a separate, calibration cell where careful control of mixture composition, temperature, and pressure was possible. Fluorescence was measured as a function of total pressure from 0 to 1450 kPa, temperature from 18 to 200°C, and fuel-to-air ratio from 0 to twice stoichiometric. The calibrated technique applied to the engine provided both qualitative and quantitative data for improving our understanding of in-cylinder mixing and comparison with engine simulation codes.

    2012-10-01

    The development and maintenance of the infrastructure, facilities, logistics and other assets of the Port of Rotterdam requires a broad spectrum of heterogeneous information. This information concerns features, which are spatially distributed above ground, underground, in the air and in the water. The data are managed in a variety of data models with varying levels of dimensionality, granularity, accuracy and up-to-dateness. Additionally increasing number of 3D design models is becoming available. This complexity of tasks and diversity of information challenges the Port authority to look for more advanced 3D solutions. This paper presents research in progress related to developing a 3D SII in support of information and process management within the Port of Rotterdam.

    This report summarizes recent research activities related to fish protection at water intake structures, with particular emphasis on research reported on or conducted at pumped cooling-water intakes. Information gathered from 51 organizations (33 utilities, seven equipment manufacturers, six research organizations, two private engineering firms, one steel mill, and two government agencies) is provided along with specific summaries of EPRI-sponsored research on behavioral barriers at pumped and hydroelectric facilities. The level of research activity indicted by utilities at pumped intakes has decreased recently, although the interest in potential plant operational impact mitigative techniques remains high. Two studies sponsored by EPRI at pumped cooling-water intake structures evaluated the individual and combined deterrent capabilities of three devices: an air bubble curtain, pneumatic guns, and underwater strobe lights. A study conducted during 1985 and 1986 at Ontario Hydro's nearshore test facility, located in Lake Ontario off the Pickering Nuclear Generating Station intake, indicated that all three devices and combinations of devices elicited an avoidance response in alewife. The pneumatic gun exhibited the highest deterrent capability and the air bubble curtain the lowest. Studies conducted using the same deterrent devices at the intake of Central Hudson Gas and Electric Corporation's Roseton Generating Station on the Hudson River did not indicate an overall avoidance response; some species-specific responses to the devices were noted. 22 refs., 9 tabs.

  7. An investigation at static conditions of nonaxisymmetric nozzle thrust reverser port geometry including effects of rounding and rotating the port corner

    NASA Technical Reports Server (NTRS)

    Arbiter, D. G.

    1985-01-01

    An investigation has been conducted in the static test facility of the Langley 16-Foot Transonic Tunnel to determine the effects of rounding and rotating the port corner of a nonaxisymmetric thrust reversing port. High pressure air was used to simulate jet exhaust at nozzle pressure ratios up to 6.0. The investigation indicates that using a rounded corner in the reverser port passage increases the discharge coefficient significantly compared to that of a sharp cornered thrust reversing port. Incorporating a rotating cylinder into the rounded corner reverser port passage provides no additional increase at cylinder revolutions per minute up to 10,000. (Revolutions per minute of 390,000 were necessary to achieve a surface velocity equal to the duct velocity.) Highest levels of discharge coefficient are obtained by providing a large, round, cylindrical surface in the port upstream wall. Locating the reverser port in a constant area duct results in higher discharge coefficients than locating the port in a convergent duct.

    2016-01-01

    Introduction Traditionally, laparoscopic mesh rectopexy is performed with four ports, in an attempt to improve cosmetic results. Following laparoscopic mesh rectopexy there is a new operative technique called single-port laparoscopic mesh rectopexy. Aim To evaluate the single-port laparoscopic mesh rectopexy technique in control of rectal prolapse and the cosmesis and body image issues of this technique. Material and methods The study was conducted in El Fayoum University Hospital between July 2013 and November 2014 in elective surgery for symptomatic rectal prolapse with single-port laparoscopic mesh rectopexy on 10 patients. Results The study included 10 patients: 3 (30%) males and 7 (70%) females. Their ages ranged between 19 years and 60 years (mean: 40.3 ±6 years), and they all underwent laparoscopic mesh rectopexy. There were no conversions to open technique, nor injuries to the rectum or bowel, and there were no mortalities. Mean operative time was 120 min (range: 90–150 min), and mean hospital stay was 2 days (range: 1–3 days). Preoperatively, incontinence was seen in 5 (50%) patients and constipation in 4 (40%). Postoperatively, improvement in these symptoms was seen in 3 (60%) patients for incontinence and in 3 (75%) for constipation. Follow-up was done for 6 months and no recurrence was found with better cosmetic appearance for all patients. Conclusions Single-port laparoscopic mesh rectopexy is a safe procedure with good results as regards operative time, improvement in bowel function, morbidity, cost, and recurrence, and with better cosmetic appearance.

    Purpose The 2-port laparoscopic appendectomy technique (TLA) is between the conventional 3-port and single-port laparoscopic appendectomy surgeries. We compared postoperative pain and cosmetic results after TLA with conventional laparoscopic appendectomy (CLA) by a 3-port device. Methods Patients undergoing TLA were matched with patients undergoing CLA between February 2015 and November 2015 at the same institution. Thirty-two patients underwent TLA with a needle grasper. The appendix was secured by a percutaneous organ-holding device (needle grasper), then removed through a puncture at McBurney's point. Another 38 patients underwent CLA. Patient demographics, operative details, and postoperative outcomes were collected and evaluated. Results One patient in the TLA group developed a wound infection and 1 patient in the CLA group developed a postoperative intra-abdominal abscess and 3 wound infections. There was no significant difference between the groups when comparing the length of hospital stay, time until oral intake, and other complications. The pain score in the first 12 hours after surgery was significanly higher in CLA group than the TLA group (P < 0.001). Operative time was significantly shorter in the CLA group compared to the TLA group (P < 0.001). Conclusion TLA using a needle grasper was associated with a significantly lower pain score 12 hours after surgery, better cosmetic results, and lower cost, than the CLA 3-port procedure because of the fewer number of ports.

  7. PIV investigation of the intake flow in a parallel valves diesel engine cylinder

    2015-11-01

    The flow of air (gas) inside the cylinder of internal combustion engines prior to compression may have a large influence on the combustion process. The structure of the in-cylinder flow, which can be swirl or tumble dominated, is to a large extent controlled by the design of the intake ports. In this study the admission flow generated by a parallel valves diesel engine cylinder head was investigated in a steady flow test bench through planar and stereo PIV measurements in both the swirl and tumble planes. By combining several sets of measurements a full three-dimensional, three-component reconstruction of the mean flow field was made. The flow out of the valves has a radial jet character, making the air hit the cylinder wall before flowing down along the cylinder wall. This leads to the formation of a recirculation bubble in the tumble plane. In the swirl plane complex jet dominated structures are found just below the valves giving rise to a counter-rotating vortex pair, where the strongest vortex becomes predominant giving rise to a single coherent swirling structure away from the cylinder head. Variations of the location and strength of the swirling structure may give rise to cycle-to-cycle variations and its stability was analysed by tracking the vortex centre.

  9. Exposure to motor vehicle emissions: An intake fraction approach

    SciTech Connect

    Marshall, Julian D.

    2002-05-01

    Motor vehicles are a significant source of population exposure to air pollution. Focusing on California's South Coast Air Basin as a case study, the author combines ambient monitoring station data with hourly time-activity patterns to determine the population intake of motor vehicle emissions during 1996-1999. Three microenvironments are considered wherein the exposure to motor vehicle emissions is higher than in ambient air: in and near vehicles, inside a building that is near a freeway, and inside a residence with an attached garage. Total motor vehicle emissions are taken from the EMFAC model. The 15 million people in the South Coast inhale 0.0048% of primary, nonreactive compounds emitted into the basin by motor vehicles. Intake of motor vehicle emissions is 46% higher than the average ambient concentration times the average breathing rate, because of microenvironments and because of temporal and spatial correlation among breathing rates, concentrations, and population densities. Intake fraction (iF) summarizes the emissions-to-intake relationship as the ratio of population intake to total emissions. iF is a population level exposure metric that incorporates spatial, temporal, and interindividual variability in exposures. iFs can facilitate the calculation of population exposures by distilling complex emissions-transport-receptor relationships. The author demonstrates this point by predicting the population intake of various primary gaseous emissions from motor vehicles, based on the intake fraction for benzene and carbon monoxide.

  10. Experimental studies on intake headloss of a blasted lake tap

    NASA Astrophysics Data System (ADS)

    Yang, James; Billstein, Mats; Engström, Fredrik; Strand, Rikard

    2014-03-01

    In existing reservoirs, construction of an intake is sometimes achieved by so-called lake tapping, a submerged tunnel piercing by blasting out the rock plug at the intake. The blasting process involves phases of rock, water, air and gas released from the explosive charge; the resulting entrance profile often differs from design assumptions. The intake headloss is a factor of concern for power generation. For a vertical intake formed by lake tapping, experiments have been carried out in a 1:30 physical model to examine the effect of entrance shapes on intake headlosses. The purpose is that, if there is potential to reduce the headlosses, the originally blasted intake shape would be modified. In the model, five alternative shapes are evaluated. The test results show that to enlarge the vertical shaft area is the most effective way to reduce the intake headloss; to further blast out a narrow channel upstream does not give much effect. Bearing in mind the risk of free-surface vortex at the intake, the influence of the intake modifications on vortex is also checked.

    2016-07-01

    Exposure to diesel engine exhaust has been linked to increased cancer risk and cardiopulmonary diseases. Diesel exhaust is a complex mixture of chemical substances, including a particulate fraction mainly composed of ultrafine particles, resulting from the incomplete combustion of fuel. Diesel trucks are known to be an important source of diesel-related air pollution, and areas with heavy truck traffic are associated with higher air pollution levels and increased public health problems. Several indicators have been proposed as surrogates for estimating exposures to diesel exhaust but very few studies have focused specifically on monitoring the ultrafine fraction through the measurement of particle number concentrations. The aim of this study is to assess occupational exposures of gate controllers at the port of Montreal, Canada, to diesel engine emissions from container trucks by measuring several surrogates through a multimetric approach which includes the assessment of both mass and number concentrations and the use of direct reading devices. A 10-day measurement campaign was carried out at two terminal checkpoints at the port of Montreal. Respirable elemental and organic carbon, PM1, PM2.5, PMresp (PM4), PM10, PMtot (inhalable fraction), particle number concentrations, particle size distributions, and gas concentrations (NO2, NO, CO) were monitored. Gate controllers were exposed to concentrations of contaminants associated with diesel engine exhaust (elemental carbon GM = 1.6 µg/m(3); GSD = 1.6) well below recommended occupational exposure limits. Average daily particle number concentrations ranged from 16,544-67,314 particles/cm³ (GM = 32,710 particles/cm³; GSD = 1.6). Significant Pearson correlation coefficients were found between daily elemental carbon, PM fractions and particle number concentrations, as well as between total carbon, PM fractions and particle number concentrations. Significant correlation coefficients were found between particle number

    The invention concerns a device for controlling the vehicles fuel-air mixture by regulating the air in the ventilation passage leading to the engine air intake from the crankcase. In a vehicle provided with a PCV valve, the device is located in the ventilation passage leading from the crankcase to the engine air intake and the device is downstream of the PCV valve. The device admits outside air to the ventilation passage to lean the gas mixture when the engine creates a vacuum less than 8 psi in the ventilation passage.

  13. Ship emissions inventory, social cost and eco-efficiency in Shanghai Yangshan port

    NASA Astrophysics Data System (ADS)

    Song, Su

    2014-01-01

    This study estimated both the in-port ship emissions inventory (CO2, CH4, N2O, PM10, PM2.5, NOx, SOx, CO, and HC) and the emission associated social cost in Yangshan port of Shanghai. A sophisticated activity-based methodology, supported by the ship-by-ship and real-time data from the modern automatic identification system (AIS), was introduced to obtain accurate estimates of ship emissions. The detailed spatial and temporal emission inventories can be used as input for air quality dispersion modeling in the port and vicinities. The social cost of the emission impact on the Yangshan port coastal regions was then assessed based on the emissions inventories. The social cost covers the impact on human health, the environment, and the climate of the coastal community. Finally, the ship emissions was combined with port's basic operation profiles, i.e. container throughput, ship calls, and port revenue, in an attempt to assess the port's “eco-efficiency”, which indicates the port performance with social-economic and environmental concerns. This study filled the gap of previous studies by providing the AIS-supported activity-based emission inventory to facilitate the social cost-benefit analysis for the emission abatement policies. The result shows that i) the amount of in-port ship emissions of CO2, CH4, N2O, PM10, PM2.5, NOx, SOx, CO, and HC in Yangshan port area was 578,444 tons, 10 tons, 33 tons, 1078 tons (PM10, inducing PM2.5), 859 tons (PM2.5 only), 10,758 tons, 5623 tons, 1136 tons, and 519 tons, respectively, with ii) a total social cost of 287 million; iii) the values of the three parameters of the port eco-efficiency performance were 36,528 per 1,000 TEU throughput, 43,993 per ship call, and 44 million per billion US$ port revenue (4.4% of port revenue), respectively in 2009.

    Hu, Dongliang; Hu, Wanli

    2014-01-01

    Background and Objectives: Our objective was to introduce our experience using modified retroperitoneoscopic port positions for operations of the upper urinary tract. Methods: We designed different trocar positions or incisions according to different surgical procedures and specimen sizes. A total of 116 patients, comprising patients with common adrenal, kidney, and ureter diseases, underwent retroperitoneoscopic operations by use of modified incisions. These patients comprised 23 with adrenal diseases, 84 with kidney diseases, and 9 with ureter diseases. The specimen was retrieved, as much as possible, through a transverse incision to produce a hidden scar after recovery. By contrast, 143 patients underwent the same or similar procedures using classical 3-port incisions. The operative time was defined as the time from skin incision to skin closure. Results: There were no significant differences in age, estimated blood loss, oral intake, and hospital stay between groups. A significant difference in favor of the modified group was noted with respect to analgesia use (diclofenac sodium, 50 mg vs 100 mg; P < .05) in all 3 modified methods, as well as in cosmetic outcome in the groups undergoing the first modification (score, 8.9 ± 2.2 VS 7.3 ± 2.8; P < .05) and second modification (score, 8.7 ± 2.5 VS 7.1 ± 2.4; P < .05). In addition, the mean operative time in patients undergoing ureter operations was shorter than that in the conventional group using classical 3-port positions (55 ± 11 minutes vs 70 ± 15 minutes, P < .05). Conclusions: Our modified retroperitoneoscopic incision is a safe, cosmetic alternative procedure for operations of the upper urinary tract. Different diseases and specimen sizes can be treated with the personalized or suitable incisions that we have introduced. PMID:25392615

    The mechanisms for controlling food intake involve mainly an interplay between gut, brain, and adipose tissue (AT), among the major organs. Parasympathetic, sympathetic, and other systems are required for communication between the brain satiety center, gut, and AT. These neuronal circuits include a variety of peptides and hormones, being ghrelin the only orexigenic molecule known, whereas the plethora of other factors are inhibitors of appetite, suggesting its physiological relevance in the regulation of food intake and energy homeostasis. Nutrients generated by food digestion have been proposed to activate G-protein-coupled receptors on the luminal side of enteroendocrine cells, e.g., the L-cells. This stimulates the release of gut hormones into the circulation such as glucagon-like peptide-1 (GLP-1), oxyntomodulin, pancreatic polypeptides, peptide tyrosine tyrosine, and cholecystokinin, which inhibit appetite. Ghrelin is a peptide secreted from the stomach and, in contrast to other gut hormones, plasma levels decrease after a meal and potently stimulate food intake. Other circulating factors such as insulin and leptin relay information regarding long-term energy stores. Both hormones circulate at proportional levels to body fat content, enter the CNS proportionally to their plasma levels, and reduce food intake. Circulating hormones can influence the activity of the arcuate nucleus (ARC) neurons of the hypothalamus, after passing across the median eminence. Circulating factors such as gut hormones may also influence the nucleus of the tractus solitarius (NTS) through the adjacent circumventricular organ. On the other hand, gastrointestinal vagal afferents converge in the NTS of the brainstem. Neural projections from the NTS, in turn, carry signals to the hypothalamus. The ARC acts as an integrative center, with two major subpopulations of neurons influencing appetite, one of them coexpressing neuropeptide Y and agouti-related protein (AgRP) that increases food

    Single port video-assisted thoracic surgery (VATS) is the most recent evolution in minimally invasive thoracic surgery. With increasing global popularity, the single port VATS approach has been adopted by experienced thoracic surgeons in many Asian countries. From initial experience of single port VATS lobectomy to the more complex sleeve resection procedures now forming part of daily practice in some Asia institutes, the region has been the proving ground for single port VATS approaches' feasibility and safety. In addition, certain technical refinements in single port VATS lung resection and lymph node dissection have also sprung from Asia. Novel equipment designed to facilitate single port VATS allowing further reduce access trauma are being realized by the partnership between surgeons and the industries. Advanced thoracoscopes and staplers that are narrower and more maneuverable are particularly important in the smaller habitus of patients from Asia. These and similar new generation equipment are being applied to single port VATS in novel ways. As dedicated thoracic surgeons in the region continue to striving for excellence, innovative ideas in single incision access including subxiphoid and embryonic natural-orifice transluminal endoscopic surgery (e-NOTES) have been explored. Adjunct techniques and technology used in association with single port VATS such as non-intubated surgery, hybrid operating room image guidance and electromagnetic navigational bronchoscopy are all in rapid development in Asia.

    Objective This study was conducted to compare the surgical outcomes between two-port access and four-port access laparoscopic ovarian cystectomy. Methods Four hundred and eighty nine patients who had received two-port access laparoscopic ovarian cystectomy (n=175) and four-port access laparoscopic ovarian cystectomy (n=314) in Chungnam National University Hospital from January 2009 to August 2012 were analyzed retrospectively. The data were compared between the bilaterality of the cysts and cyst diameter of less than 6 cm and 6 cm or more. Results There were no significant differences in patient's age, parity, body weight, body mass index and history of previous surgery between the two-port and four-port access laparoscopy group. Bilaterality of ovarian cysts was more in fourport access laparoscopy group (13.7% vs. 32.5%, P=0.000). There were no significant differences in operation time, hemoglobin change, hospital stay, adhesiolysis, transfusion, and insertion of hemo-vac between the two-port and four-port access laparoscopy group for size matched compare. However additional analgesics were more in four-port access laparoscopy group for unilateral ovarian cystectomy. Conclusion Two-port access laparoscopic surgery was feasible and safe for unilateral and bilateral ovarian cystectomy compare with four-port access laparoscopic surgery. PMID:25264528

  15. Design and evaluation of candidate pressure ports for the HYFLITE experiment

    NASA Technical Reports Server (NTRS)

    Teter, John E., Jr.; Cleckner, Craig S.; Vontheumer, Alfred E.

    1994-01-01

    A concept for placing a pressure transducer directly in a shuttle type tile was developed at Langley Research Center. A 5 inch long quartz with a .020 inch inner diameter provides the thermal isolation necessary to allow 2800 F surface pressure measurements to be taken by pressure transducer rated at 250 F. The assembly is potted in place with RTV 560 in a piece of FRCI-12 thermal protection system insulation tile. The integrity of the thermal protection system is maintained even with the intrusion of the pressure port assembly and the pressure port does not disrupt the air flow across the lifting body. Approximately 200 of these pressure ports are to be used in each of the Hypersonic Flight Experiment (HYFLITE) flight tests. Initial vibroacoustic and aerothermal testing of the pressure port designs have been completed at Langley Research vibration laboratory and the 20 MWatt 2 x 9 turbulent duct facility at Ames Research Center. The performance of the pressure ports were found to be well within the required design limits for all cases. In addition, a failure mode in which the entire pressure port assembly was removed proved to be a begin case.

  16. An Investigation on the Effects of Ship Sourced Emissions in Izmir Port, Turkey

    Maritime transportation is a major source of climate change and air pollution. Shipping emissions cause severe impacts on health and environment. These effects of emissions are emerged especially in territorial waters, inland seas, canals, straits, bays, and port regions. In this paper, exhaust gas emissions from ships in Izmir Port, which is one of the main ports in Turkey, are calculated by the ship activity-based methodology. Total emissions from ships in the port is estimated as 1923 ton y−1 for NOx, 1405 ton y−1 for SO2, 82753 ton y−1 for CO2, ton y−1 for HC, and 165 ton y−1 for PM in the year 2007. These emissions are classified regarding operation modes and types of ships. The results are compared with the other studies including amounts of exhaust pollutants generated by ships. According to the findings, it is clear that the ships calling the Izmir Port are important air polluting causes of the Izmir city and its surroundings. PMID:24198720

    2015-05-01

    When the scene observed by an imaging Fourier-Transform Spectrometer is not stable in amplitude or in position during the time it takes to acquire to spectrum, spectro-radiometric artifacts are generated. These artifacts reduce the radiometric accuracy and may also damage the spectral line shape. The displacements of the scene in the field of view can be due to air turbulence, platform jitters or scene jitters. We describe an automated correction process based on the information provided by the second output port of a two-port imaging FTS. Corrected and uncorrected data will be compared.

  20. Hot Corrosion at Air-Ports in Kraft Recovery Boilers

    SciTech Connect

    Holcomb, Gordon R.; Covino, Bernard S., Jr.; Russell, James H.

    2003-01-01

    Hot corrosion can occur on the cold-side of airports in Kraft recovery boilers. The primary corrosion mechanism involves the migration of sodium hydroxide and potassium hydroxide vapors through leaks in the furnace wall at the airports and their subsequent condensation. It has been reported that stainless steel is attacked much faster than carbon steel in composite tubes, and that carbon steel tubing, when used with a low-chromium refractory, does not exhibit this type of corrosion. For hot corrosion fluxing of metal oxides, either acidic or basic fluxing takes place, with a solubility minimum at the basicity of transition between the two reactions. For stainless steel, if the basicity of the fused salt is between the iron and chromium oxide solubility minima, then a synergistic effect can occur that leads to rapid corrosion. The products of one reaction are the reactants of the other, which eliminates the need for rate-controlling diffusion. This effect can explain why stainless steel is attacked more readily than carbon steel.

  1. Multi-port valve assembly

    DOEpatents

    Guggenheim, S. Frederic

    1986-01-01

    A multi-port fluid valve apparatus is used to control the flow of fluids through a plurality of valves and includes a web, which preferably is a stainless steel endless belt. The belt has an aperture therethrough and is progressed, under motor drive and control, so that its aperture is moved from one valve mechanism to another. Each of the valve mechanisms comprises a pair of valve blocks which are held in fluid-tight relationship against the belt. Each valve block consists of a block having a bore through which the fluid flows, a first seal surrounding the bore and a second seal surrounding the first seal, with the distance between the first and second seals being greater than the size of the belt aperture. In order to open a valve, the motor progresses the belt aperture to where it is aligned with the two bores of a pair of valve blocks, such alignment permitting a flow of the fluid through the valve. The valve is closed by movement of the belt aperture and its replacement, within the pair of valve blocks, by a solid portion of the belt.

  12. Inhibition of food intake.

    Young, Andrew

    2005-01-01

    Over 100 publications, principally from five groups, describe an effect of amylin and amylin analogs in inhibition of food intake in animals and humans. The major groups contributing to this area are those of the following: Chance and Balasubramaniam (Balasubramaniam et al., 1991a,b; Chance et al., 1991a,b, 1992a,b, 1993). Morley, Flood, and Edwards (Edwards and Morley, 1992; Flood and Morley, 1992; Macintosh et al., 2000; Morley and Flood, 1991, 1994; Morley et al., 1992, 1993, 1994, 1995, 1996, 1997). Lutz, Geary, and others (Barth et al., 2003; Del Prete et al., 2002; Lutz et al., 1994, 1995a,b, 1996a,b, 1997a,b, 1998a,b,c, 2000a,b, 2001a,b,c, 2003; Mollet et al., 2001, 2003a,b, 2004; Riediger et al., 2002, 2004; Rushing et al., 2000a,b, 2001, 2002). Workers at Amylin Pharmaceuticals Inc., or their collaborators (Bhavsar et al., 1995, 1996, 1997a, 1998; Birkemo et al., 1995; Chapman et al., 2004a,b; Edwards et al., 1998; Feinle et al., 2002; Mack et al., 2003; Riediger et al., 1999; Roth et al., 2004; Watkins et al., 1996; Weyer et al., 2004; Young, 1997; Young and Bhavsar, 1996). Arnelo, Reidelberger, and others (Arnelo et al., 1996a,b, 1997a,b, 1998, 2000; Fruin et al., 1997; Granqvist et al., 1997; Reidelberger et al., 2001, 2002, 2004). The magnitude of amylin inhibition of food intake, and its potency for this effect when delivered peripherally, suggests a physiological role in satiogenesis. Increases in food intake following disruption of amylin signal-signaling (e.g., with amylin receptor blockade, or with amylin gene knock-out mice) further support a role of endogenous amylin to tonically restrict nutrient intake. In addition, synergies with other endogenous satiety agents may be present, and convey greater physiological importance than is conveyed by single signals. The anorectic effect of amylin is consistent with a classic amylin pharmacology. The anorectic effect of peripheral amylin appears principally due to a direct action at the area postrema

  20. The Potential Impacts of OTEC Intakes on Aquatic Organisms at an OTEC Site under Development on Kauai, HI

    SciTech Connect

    Oney, Stephen K.; Hogan, Timothy; Steinbeck, John

    2013-08-31

    Ocean thermal energy conversion (OTEC) is a marine renewable energy technology with the potential to contribute significantly to the baseload power needs of tropical island communities and remote U.S. military installations. As with other renewable energy technologies, however, there are potential challenges to its commercialization: technological, financial, social, and environmental. Given the large volumes of seawater required to drive the electricity-producing cycle, there is potential for the intakes to negatively impact the marine resources of the source waterbody through the impingement and entrainment of marine organisms. The goal of this project was to identify feasible warm water intake designs for a land-based OTEC facility proposed for development in Port Allen, Kauai and to characterize the populations of ichthyoplankton near the proposed warm water intake location that could be at risk of entrainment. The specific objectives of this project were to: • Complete a site-specific assessment of available and feasible warm water intake technologies to determine the best intake designs for minimizing impacts to aquatic organisms at the proposed land-based OTEC site in Port Allen, Kauai. • Complete a field sampling program to collect biological data to characterize the baseline populations of ichthyoplankton near the sites being considered for the warm water intake at the proposed land-based OTEC site in Port Allen, Kauai. Various intake design options are presented with the focus on providing adequate environmental protection to the local ichthyoplankton population while providing an economically viable intake option to the OTEC developer. Further definition by NOAA and other environmental regulators is required to further refine the designs presented to meet all US regulations for future OTEC development.

    2014-04-15

    In this paper an identification and selection of Environmental Performance Indicators (EPIs) in port areas has been conducted. A comprehensive inventory of existing EPIs in use in the seaport sector has been identified for monitoring performance of operational (e.g. dust, noise, dredging, and waste), managerial (e.g. certification, compliance, and complaints) and environmental condition (e.g. air, water, sediment and ecosystems). These indicators have been filtered against specific criteria and have been assessed and evaluated by port stakeholders in order to obtain a final set of indicators suitable to be implemented at EU level. A user friendly tool has been developed specifically to assist port authorities in calculating and reporting the proposed indicators. This study has drawn on major research projects to blend academic research with input from marine professionals in order to identify, select, evaluate and validate EPIs that are acceptable and feasible to the sector, and practicable in their application and implementation.

    2016-02-01

    When in port, ships burn marine diesel in on-board generators to produce electricity and are significant contributors to poor local and regional air quality. Supplying ships with grid electricity can reduce these emissions. We use two integrated assessment models to quantify the benefits of reducing the emissions of NOX, SO2, PM2.5, and CO2 that would occur if shore power were used. Using historical vessel call data, we identify combinations of vessels and berths at U.S. ports that could be switched to shore power to yield the largest gains for society. Our results indicate that, depending on the social costs of pollution assumed, an air quality benefit of $70-150 million per year could be achieved by retrofitting a quarter to two-thirds of all vessels that call at U.S. ports. Such a benefit could be produced at no net cost to society (health and environmental benefits would be balanced by the cost of ship and port retrofit) but would require many ships to be equipped to receive shore power, even if doing so would result in a private loss for the operator. Policy makers could produce a net societal gain by implementing incentives and mandates to encourage a shift toward shore power. PMID:26713768

    2000-04-01

    Power plant condenser cooling water intake entrainment of fish eggs and larvae is becoming an issue in evaluating environmental impacts around the plants. Methods are required to evaluate intake entrainment on different types of water bodies. Presented in this paper is a derivation of the basic relationships for evaluating entrainment from the standing crop of fish eggs and larvae for different regions of a water body, and evaluating the rate of entrainment from the standing crop. These relationships are coupled with a 3D hydrodynamic and transport model that provides the currents and flows required to complete the entrainment evaluation. Case examples are presented for a simple river system, and for the more complex Delaware River Estuary with multiple intakes. Example evaluations are made for individual intakes, and for the cumulative impacts of multiple intakes.

    The single port laparoscopic method was first used in 1999 by Bresadola for cholecystectomy. Nearly a decade later, in 2008, the first single port right hemicolectomy was reported by Bucher and others in a case involving an ascending colon polyp (1,2). The continuous technological evolutional lows the first single port right hemicolectomy 17 years after the first laparoscopic hemicolectomy (1991) which was initially met with reluctance and after has gained a well-established place in the range of colorectal surgery (2). Single port access, as well as NOTES, provides, in comparison with the standard laparoscopic procedure, the aesthetic benefit, the decrease of postoperative pain and a shorter duration of hospitalization, while in terms of disadvantages, we could mention a longer surgery duration due to fewer opportunities of triangulation and vision (3,4). The reduction of postoperative pain plus the good aesthetic results with no significant increase of postoperative complications, already proved by retrospective studies, require confirmation by randomized studies envisaged by trial TRUE in France (5). Single port right hemicolectomy can be achieved with oncologic results similar to standard laparoscopic surgery, having very good postoperative results in terms of aesthetics and reduced postoperative pain (5,6,7).

    Background To summarize our experiences of single-port, two-port vs. three-port VATS pulmonary resection for lung cancer patients. Methods Data of consecutive 1,553 patients who underwent video assisted thoracoscopic surgery (VATS) pulmonary resection for lung cancer in the Department of Thoracic Surgery of Cancer Hospital of Chinese Academy of Medical Sciences and Peking Union Medical College between November 2014 and January 2016 were prospectively collected and analyzed. A propensity-matched analysis was used to compare the short-term outcomes of lung cancer patients who received VATS single-port, two-port and three-port pulmonary resection. Results There were 716 males and 837 females. The mean age was 58.90 years (range, 25–82 years) and the conversion rate was 2.7% (42/1,553) in this cohort. After propensity score matching, there were 207 patients in single-port and two-port group, and 680 patients in three-port group. Propensity-matched analysis demonstrated that there were no significant differences in duration of operation (129 vs. 131 min, P=0.689), intra-operative blood loss (63 vs. 70 mL, P=0.175), number of dissected lymph nodes (12 vs. 13, P=0.074), total hospital expense (﹩9,928 vs. ﹩9,956, P=0.884) and cost of operation (﹩536 vs. ﹩535, P=0.879) between VATS single-port, two-port and conventional three-port pulmonary resection groups. There was no significant difference in the complication rate between two groups (5.3% vs. 4.7%, P=0.220). However, compared with three-port group, patients who underwent single port and two-port experienced shorter postoperative length of stay (6.24 vs. 5.61 d, P=0.033), shorter duration of chest tube (4.92 vs. 4.25 d, P=0.008), and decreased volume of drainage (926 vs. 791 d, P=0.003). Conclusions The short term outcomes between VATS single-port, two-port and conventional three-port groups for the surgical treatment of lung cancer were comparable. However, compared with three-port VATS pulmonary resection

  13. Indoor Air Quality

    NASA Astrophysics Data System (ADS)

    Miyazaki, Takeji

    The reduction of intake of outdoor air volume in air conditioned buildings, adopted as the strategy for saving energy, has caused sick building syndrome abroad. Such symptoms of sick building as headache, stimuli of eye and nose and lethargy, appears to result from cigarette smoke, folmaldehyde and volatile organic carbons. On the other hand, in airtight residences not only carbon monoxide and nitrogen oxides from domestic burning appliances but also allergens of mite, fungi, pollen and house dust, have become a subject of discussion. Moreover, asbestos and radon of carcinogen now attract a great deal of attention. Those indoor air pollutants are discussed.

  14. Porting salinas to the windows platform.

    2006-06-01

    The ASC program has enabled significant development of high end engineering applications on massively parallel machines. There is a great benefit in providing these applications on the desktop of the analysts and designers, at least insofar as the small models may be run on these platforms, thus providing a tool set that spans the application needs. This effort documents the work of porting Salinas to the WINDOWS{trademark} platform. Selection of the tools required to compile, link, test and run Salinas in this environment is discussed. Significant problems encountered along the way are listed along with an estimation of the overall cost of the port. This report may serve as a baseline for streamlining further porting activities with other ASC codes.

  15. Effect of piano-key shape inlet on critical submergence at a vertical pipe intake

    NASA Astrophysics Data System (ADS)

    Shemshi, R.; Kabiri-Samani, A.

    2012-11-01

    Intake vortices are the result of angular momentum conservation at the flow constriction, where angular velocity increases with a decrease in the cross sectional area. The common solution for avoiding air-entrainment and swirl is to provide sufficient submergence to the intake. If the required approach flow conditions can not be met to avoid swirl and air entrainment, other approaches for preventing vortices at water intakes are considered. There are several means of avoiding air-entrainment, where the most cost-effective option is often determined by a physical model study. Among the most economical and common measures of reducing the effect of air-entrainment and swirl strength, is the optimized shape of inlet for instance by installing a Piano-Key inlet over the pipe intake. If Piano-Key inlet is used, then, its' optimum geometry should be studied experimentally. Since there is not any realized guidance for the use of Piano-Key inlets in pipe intakes, hence, a comprehensive set of model experiments have been carried out using Piano-Key inlets with different dimensions, with respect to the vertical pipe intakes, and four different pipe diameters of (D=) 75, 100, 125 and 150 mm. Results showed that by employing a Piano-Key inlet over the vertical pipe intake, the critical submergence reduces significantly. Fianally, according to the results, the effect of Piano-Key inlet geometry on critical submergence were evaluated in the form of realized relationships which would be of practical interest for design engineers.

  16. Laser treatment of port-wine stains

    PubMed Central

    2015-01-01

    Port-wine stains are a type of capillary malformation affecting 0.3% to 0.5% of the population. Port-wine stains present at birth as pink to erythematous patches on the skin and/or mucosa. Without treatment, the patches typically darken with age and may eventually develop nodular thickening or associated pyogenic granuloma. Laser and light treatments provide improvement through selective destruction of vasculature. A variety of vascular-selective lasers may be employed, with the pulsed dye laser being the most common and well studied. Early treatment produces more optimal results. Advances in imaging and laser treatment technologies demonstrate potential to further improve clinical outcomes. PMID:25624768

  17. Dietary Salt Intake and Hypertension

    PubMed Central

    2014-01-01

    Over the past century, salt has been the subject of intense scientific research related to blood pressure elevation and cardiovascular mortalities. Moderate reduction of dietary salt intake is generally an effective measure to reduce blood pressure. However, recently some in the academic society and lay media dispute the benefits of salt restriction, pointing to inconsistent outcomes noted in some observational studies. A reduction in dietary salt from the current intake of 9-12 g/day to the recommended level of less than 5-6 g/day will have major beneficial effects on cardiovascular health along with major healthcare cost savings around the world. The World Health Organization (WHO) strongly recommended to reduce dietary salt intake as one of the top priority actions to tackle the global non-communicable disease crisis and has urged member nations to take action to reduce population wide dietary salt intake to decrease the number of deaths from hypertension, cardiovascular disease and stroke. However, some scientists still advocate the possibility of increased risk of CVD morbidity and mortality at extremes of low salt intake. Future research may inform the optimal sodium reduction strategies and intake targets for general populations. Until then, we have to continue to build consensus around the greatest benefits of salt reduction for CVD prevention, and dietary salt intake reduction strategies must remain at the top of the public health agenda.

    The missile trocar was developed for controllable entry force, smaller fascial defects and post-operative pain improvement. The trocar was composed of a fascial-dilating long-conical head and a handle. Accompanied with this trocar, the authors designed a rectus sheath-hooking instrument to promote negative intra-abdominal pressure during the trocar puncture. The hooking procedure allowed room air to pass through the central canal of the trocar and fill the space between the intestinal loops and the trocar tip. The abdominal access procedure succeeded in forty-five attempts in fresh cadavers. No second attempt was done. The trocar accessed into the peritoneal cavity at every attempt without intestinal penetration. The missile trocar may be an alternative device for establishment of the primary port. Its efficacy and safety still has to be proved. PMID:12188430

  16. Governance and management of a deepwater port: a case study

    SciTech Connect

    Olcott, E.S.

    1985-10-01

    A deepwater port is many things to many people. Clearly, the Port of Rotterdam, the largest port in the world, is a deepwater port with its 75 feet of water, more than $1.5 billion invested in facilities and its annual volume of more than 280 million metric tons of cargo in a broad commodity mix. Bantry Bay in Ireland, a major import petroleum and trans-shipment facility for Britain and the European continent, is a deepwater port. So also is the Louisiana Offshore Oil Port (LOOP), comprised of a single-point mooring buoy and sophisticated petroleum distribution system, located in deep water off the Gulf coast of the US. And so is the Port of Seattle a deepwater port, located in the natural deep water of Puget Sound. Deep drafts ports abound in Japan where as many as nine ports have been developed with water depths in excess of 55 feet.

  3. Low Back Pain in Port Machinery Operators

    NASA Astrophysics Data System (ADS)

    BOVENZI, M.; PINTO, I.; STACCHINI, N.

    2002-05-01

    The occurrence of several types of low back pain (LBP) was investigated by a standardized questionnaire in a group of 219 port machinery operators exposed to whole-body vibration (WBV) and postural load and in a control group of 85 maintenance workers employed at the same transport company. The group of port machinery operators included 85 straddle carrier drivers, 88 fork-lift truck drivers, and 46 crane operators. The vector sum of the frequency-weighted r.m.s. acceleration of vibration measured on the seatpan of port vehicles and machines averaged 0·90 m/s2 for fork-lift trucks, 0·48 m/s2 for straddle carriers, 0·53 m/s2 for mobile cranes, and 0·22 m/s2 for overhead cranes. The 12-month prevalence of low back symptoms (LBP, sciatic pain, treated LBP, sick leave due to LBP) was significantly greater in the fork-lift truck drivers than in the controls and the other two groups of port machinery operators. After adjusting for potential confounders, the prevalence of low back symptoms was found to increase with the increase of WBV exposure expressed as duration of exposure (driving years), equivalent vibration magnitude (m/s2), or cumulative vibration exposure (yr m2/s4). An excess risk for lumbar disc herniation was observed in the port machinery operators with prolonged driving experience. In both the controls and the port machinery operators, low back complaints were strongly associated with perceived postural load assessed in terms of frequency and/or duration of awkward postures at work. Multivariate analysis showed that vibration exposure and postural load were independent predictors of LBP. Even though the cross-sectional design of the present study does not permit firm conclusions on the relationship between WBV exposure and low back disorders, the findings of this investigation provide additional epidemiological evidence that seated WBV exposure combined with non-neutral trunk postures, as while driving, is associated with an increased risk of long

  5. Salt intake and hypertension therapy.

    PubMed

    2002-01-01

    Hypertension is a risk factor for cardiovascular and renal organ damage. Environmental conditions affect the development of high blood pressure (BP), although genetic influences are also important. Current international guidelines recommend reducing dietary sodium to no more than 100 mmol (about 2.4 g sodium or approximately 6 g salt) per day to prevent BP rising; the current intake of sodium in industrialized countries is approximately double the recommended amount. Clinical trials (DASH and TOHP studies) have shown that dietary factors are fundamental in the prevention and control of BP. Low dietary sodium intake is particularly effective in preventing hypertension in subjects with an increased risk such as the overweight, borderline hypertensives or the elderly. A low-salt diet combined with anti-hypertensive therapies facilitates BP reduction independent of race. The hypotensive effect of calcium channel blockers is less dependent on salt intake than other drugs, such as ACE inhibitors or diuretics. Reduced sodium intake associated with other dietary changes (such as weight loss, and increasing potassium, calcium and magnesium intake) are important instruments for the prevention and therapy of hypertension.

    Adding similar features and bug fixes often requires porting program patches from reference implementations and adapting them to target implementations. Porting errors may result from faulty adaptations or inconsistent updates. This paper investigates (I) the types of porting errors found in practice, and (2) how to detect and characterize potential porting errors. Analyzing version histories, we define five categories of porting errors, including incorrect control- and data-flow, code redundancy, inconsistent identifier renamings, etc. Leveraging this categorization, we design a static control- and data-dependence analysis technique, SPA, to detect and characterize porting inconsistencies. Our evaluation on code from four open-source projects shows thai SPA can dell-oct porting inconsistencies with 65% to 73% precision and 90% recall, and identify inconsistency types with 58% to 63% precision and 92% to 100% recall. In a comparison with two existing error detection tools, SPA improves precision by 14 to 17 percentage points

    An investigation was made with a specially designed engine to determine the scavenging characteristics of a large number of inlet-port shapes and arrangements and the optimum port arrangement and timing for this particular type of engine. A special cylinder construction permitted wide variations in timing for this particular type of engine. A special cylinder construction permitted wide variations in timing as well as in shape and arrangement of both the inlet and exhaust ports. The study of the effect of port shape combinations and timings on engine performance was made using illuminating gas as a fuel. Through variations in inlet-port arrangement and port timings, the value of the scavenging efficiency was increased from an original 44 percent to approximately 67 percent with a corresponding increase in power. With the optimum port arrangement and timing determined, a large number of performance runs were made under both spark-ignition and compression-ignition operation.

    Karabicak, Ilhan; Karabulut, Kagan

    2016-01-01

    Nowadays, the trend is to perform surgeries with “scarless” incisions. In light of this, the single-port laparoscopic surgery (SPLS) technique is rapidly becoming widespread due to its lack of invasiveness and its cosmetic advantages, as the only entry point is usually hidden in the umbilicus. The interest in “scarless” liver resections did not grow as rapidly as the interest in other scarless surgeries. Hepatopancreatobiliary surgeons are reluctant to operate a malignant lesion through a narrow incision with limited exposure. There are concerns over adverse oncological outcomes for single-port laparoscopic liver resections (SPL-LR) for hepatocellular carcinoma or metastatic colorectal cancer. In addition, getting familiar with using the operating instruments through a narrow incision with limited exposure is very challenging. In this article, we reviewed the published literature to describe history, indications, contraindications, ideal patients for new beginners, technical difficulty, advantages, disadvantages, oncological concern and the future of SPL-LR.

    The tsunamis that have occurred in many places around the world over the past decade have taken a heavy toll on human lives and property. The eastern coast of the Korean Peninsula is not safe from tsunamis, particularly the eastern coastal areas, which have long sustained tsunami damage. The aim of this study was to mitigate the casualties and property damage on the east eastern coast by developing a proper tsunami response system for important ports and harbors with high population densities and high concentrations of key national industries. For study purposes, the government-managed major international trade ports and coastal harbors were selected and an effective tsunami response system was formulated based on field surveys and related literature.

    Port wine stain (PWS), also called nevus flammeus, is a congenital, cutaneous vascular malformation involving post-capillary venules which produce a light pink to red to dark-red-violet discoloration of human skin [1]. PWS occurs in an estimated 3 children per 1000 live births, affecting males and females and all racial groups equally [2]. There appears to be no hereditary predilection for PWS within families. There are no known risk factors or ways to prevent PWS.

    Affordable and realistic three dimensional visualization technology can be applied to large scale constructive simulations such as the port simulation model, PORTSIM. These visualization tools enhance the experienced planner's ability to form mental models of how seaport operations will unfold when the simulation model is implemented and executed. They also offer unique opportunities to train new planners not only in the use of the simulation model but on the layout and design of seaports. Simulation visualization capabilities are enhanced by borrowing from work on interface design, camera control, and data presentation. Using selective fidelity, the designers of these visualization systems can reduce their time and efforts by concentrating on those features which yield the most value for their simulation. Offering the user various observational tools allows the freedom to simply watch or engage in the simulation without getting lost. Identifying the underlying infrastructure or cargo items with labels can provide useful information at the risk of some visual clutter. The PortVis visualization expands the PORTSIM user base which can benefit from the results provided by this capability, especially in strategic planning, mission rehearsal, and training. Strategic planners will immediately reap the benefits of seeing the impact of increased throughput visually without keeping track of statistical data. Mission rehearsal and training users will have an effective training tool to supplement their operational training exercises which are limited in number because of their high costs. Having another effective training modality in this visualization system allows more training to take place and more personnel to gain an understanding of seaport operations. This simulation and visualization training can be accomplished at lower cost than would be possible for the operational training exercises alone. The application of PORTSIM and PortVis will lead to more efficient

    Underwater photogrammetry using consumer grade photographic equipment can be feasible for different applications, e.g. archaeology, biology, industrial inspections, etc. The use of a camera underwater can be very different from its terrestrial use due to the optical phenomena involved. The presence of the water and camera pressure housing in front of the camera act as additional optical elements. Spherical dome ports are difficult to manufacture and consequently expensive but at the same time they are the most useful for underwater photogrammetry as they keep the main geometric characteristics of the lens unchanged. Nevertheless, the manufacturing and alignment of dome port pressure housing components can be the source of unexpected changes of radial and decentring distortion, source of systematic errors that can influence the final 3D measurements. The paper provides a brief introduction of underwater optical phenomena involved in underwater photography, then presents the main differences between flat and dome ports to finally discuss the effect of manufacturing on 3D measurements in two case studies.

    1980-12-23

    An internal combustion engine has a fuel injection pump and an air/fuel ratio controller. The controller has a lever that is connected to the pump lever. An aneroid moves the controller lever as a function of changes in intake manifold vacuum to maintain a constant air/fuel ratio to the mixture charge. A fuel enrichment linkage is provided that modifies the movement of the fuel flow control lever by the aneroid in response to changes in manifold gas temperature levels and exhaust gas recirculation to maintain the constant air/fuel ratio. A manual override is provided to obtain a richer air/fuel ratio for maximum acceleration.

    We describe a novel minimally invasive procedure: dual-port laparoscopic abdominoperineal resection using a SILS port, and report our experience of using this to treat ten patients with lower rectal cancer. A SILS port was placed in the left lower quadrant at the intended colostomy site. A 5-mm trocar was inserted at the umbilicus at the subsequent drain site. Via a standard laparoscopic medial-to-lateral approach, the inferior mesenteric artery and vein were ligated and total mesorectal excision was performed. Via a perineal approach, the specimen was retrieved from the perineal wound, and a sigmoid colostomy was created at the site of the SILS port. Ten consecutive patients with lower rectal cancer at clinical stage T3 or lower underwent the procedure at our institution. The procedure was completed successfully in all patients, without any intraoperative problems and all postoperative outcomes were satisfactory. Thus, dual-port laparoscopic abdominoperineal resection can be performed safely and feasibly in selected patients. PMID:26220049

    Purpose We review the literature and describe our technique for laparoendoscopic single-site orchidopexy using a glove port and rigid instruments. We assessed the feasibility and outcomes of this procedure. Materials and Methods We retrospectively reviewed the case records of all children who had undergone laparoendoscopic single-site orchidopexy by use of a surgical glove port and conventional rigid instruments for a nonpalpable intraabdominal testis between January 2013 and September 2014. Results Data from a total of 20 patients were collected. The patients' mean age was 18 months. All cases had a nonpalpable unilateral undescended testis. Fourteen patients (70%) had an undescended testis on the right side and six patients (30%) had an undescended testis on the left side. Seventeen patients underwent primary orchidopexy. Three patients underwent single-port laparoscopic Fowler-Stephens orchidopexy for the first and the second stage. Average operating time was 57 minutes (range, 40 to 80 minutes). No patient was lost to follow-up. At follow-up, 2 testes were found to have retracted out of the scrotum and these were successfully dealt with in a second operation. One testis was hypoplastic in the scrotal pouch. There were no signs of umbilical hernia. Conclusions Single-port laparoscopic orchidopexy using a glove port and rigid instruments is technically feasible and safe for various nonpalpable intraabdominal testes. However, surgical experience and long-term follow-up are needed to confirm the superiority of this technique. PMID:26568797

    The transshipment is an important issue in the current marine transportation. This paper constructed a mathematical programming model to elaborate the transshipment port selection for the shipping company. This model is tested by the data collected from the ports of Hong Kong and Kaohsiung. The results show that this model can be used to explain the transshipment competition relationship between the ports of Hong Kong and Kaohsiung well. A sensitivity analysis was also executed. The sensitivity analysis results showed that both the port of Hong Kong and Kaohsiung should decrease the charges of port and increase the efficiency of loading and discharging. Based on the sensitivity analysis results, some interesting conclusions and helpful suggestions were obtained for the managers of the ports of Hong Kong and Kaohsiung to improve their port management.

    Phosphorus is necessary for bone mineralization. Although adequate phosphorus intake is essential for skeletal mineralization, it is reported that excessive phosphorus intake can induce deleterious effect on bone. Recently, since the Japanese diet has been westernized, phosphorus intake by the meat and dairy products has increased. Furthermore, along with the development of processed foods, excessive intake of inorganic phosphorus from food additives has become a problem. An adverse effect on parathyroid hormone (PTH) secretion from high phosphorus intake was seen only when calcium intake was inadequate. Dietary calcium to phosphorus ratio can be considered as one of the indicators that can predict the health of the bone. PMID:26119308

    Purpose. The purpose of this study was to evaluate radiological-interventional central venous port catheter corrections in migrated/malpositioned catheter tips. Materials and Methods. Thirty patients with migrated/malpositioned port catheter tips were included in this retrospective analysis. To visualize the catheter patency a contrast-enhanced port catheter series was performed, followed by transfemoral port catheter correction with various 5-F angiographic catheters (pigtail; Sos Omni), gooseneck snares, or combinations thereof. Results. One patient showed spontaneous reposition of the catheter tip. In 27 of 29 patients (93%), radiological-interventional port catheter correction was successful. In two patients port catheter malposition correction was not possible, because of the inability to catch either the catheter tip or the catheter in its course, possibly due to fibrin sheath formation with attachment of the catheter to the vessel wall. No disconnection or port catheter dysfunction was observed after correction. Conclusions. We conclude that in migrated catheter tips radiological-interventional port catheter correction is a minimally invasive alternative to port extraction and reimplantation. In patients with a fibrin sheath and/or thrombosis port catheter correction is often more challenging.

    Bonjour, Jean-Philippe

    2011-03-01

    Adequate nutrition plays an important role in the development and maintenance of bone structures resistant to usual mechanical stresses. In addition to calcium in the presence of an adequate supply of vitamin D, dietary proteins represent key nutrients for bone health and thereby function in the prevention of osteoporosis. Several studies point to a positive effect of high protein intake on bone mineral density or content. This fact is associated with a significant reduction in hip fracture incidence, as recorded in a large prospective study carried out in a homogeneous cohort of postmenopausal women. Low protein intake (< 0.8 g/kg body weight/day) is often observed in patients with hip fractures and an intervention study indicates that following orthopedic management, protein supplementation attenuates post-fracture bone loss, tends to increase muscle strength, and reduces medical complications and rehabilitation hospital stay. There is no evidence that high protein intake per se would be detrimental for bone mass and strength. Nevertheless, it appears reasonable to avoid very high protein diets (i. e. more than 2.0 g/kg body weight/day) when associated with low calcium intake (i. e. less than 600 mg/day). In the elderly, taking into account the attenuated anabolic response to dietary protein with ageing, there is concern that the current dietary protein recommended allowance (RDA), as set at 0.8 g/kg body weight/day, might be too low for the primary and secondary prevention of fragility fractures.

    Reduced port laparoscopic surgery has been used increasingly. It is a concept that has grown out of the various efforts aimed at minimally invasive surgery, with SILS being the ultimate reduced port technique. Reduced port laparoscopic surgery has been used to perform sleeve gastrectomy in bariatric surgery and excision of benign gastric submucosal tumor, applications that generally do not require lymph node dissection or complicated reconstruction. It can be done safely, result in a permanent cure, and offer good cosmetic outcomes. Reduced port laparoscopic surgery for gastric cancer has a short history, and its usefulness has not yet been fully established. This review describes the present situation and challenges faced as well as standardized procedures and the future prospects of reduced port laparoscopic gastrectomy for gastric cancer, which my team performs almost daily. These aspects of reduced port laparoscopic surgery are presented in light of the literature. PMID:25496345

  6. Is multi-port ATE in your future

    NASA Astrophysics Data System (ADS)

    Monie, V.; Kovel, D. M.

    The history of ATE is surveyed, with attention given to significant technical advances made during the past few years. Multi-port testing is seen as a logical extension of engineering attempts to extract the maximum value for the ATE dollar invested. Particular attention is given to the economics of multi-port ATE. It is shown that the cost/throughput ratio of a dual-port test set is 40% greater than a single port test set. The benefits of increased test set availability and the associated logistics costs are stressed. The numerous economic benefits are matched by the technical advantages, which are also discussed in detail. Potential problems in a dual-port ATE are identified, and solutions are suggested. It is shown that a successful dual-port ATE is one that not only solves real-life testing problems but also solves problems of resource competition and allocation.

  16. Recent sedimentation, northeastern Port Valdez, Alaska

    NASA Astrophysics Data System (ADS)

    Palmer, Harold D.

    1981-09-01

    Sediments accumulating on the northeastern shore of Port Valdez, a fjord leading to Prince William Sound in southern Alaska, are derived from both deltaic and alluvial fan processes. The resulting thick wedge of Recent silts, sands, shells and gravels lies atop irregular ridges of local graywacke bedrock and scattered till deposits. Seismic reflection profiling augmented by soil borings indicates that rapid infilling and upbuilding has occurred at this site. Evidence of slumping suggests general instability of steep submarine slopes in an area characterized by strong earthquakes and large tidal ranges.

    1993-05-01

    We discussed a second entry port for the Accelerator Test Facility (ATF) injection system at Brookhaven National Laboratory, which consists of a photocathode rf gun and a straight - ahead beamline directly into the 50 MeV linac. The proposed second entry port should improve the beam quality and lower the emittance needed for FEL (Free Electron Laser), and laser - acceleration experiments. A discussion on the laser driven high brightness photoelectrons through the primary entry port (a low energy 180 degrees achromatic double bend transport line) now in operation, and a beam analysis for the proposed secondary port is also given.

    2015-01-01

    Single-incision laparoscopic surgery has gained increasing attention due to its potential to improve the benefits of laparoscopic surgery. However, inconvenience remains for inexperienced surgeons during surgery when instruments conflict with each other, and a glove port is used hesitantly for such diagnosis related groups (DRG) because of its high cost. Authors made a new glove port by an odd surgical gloves and one wound protectors. This glove port is ease to make besides being convenient to us, and inexpensive. This new glove port has the benefit of easy utilization and cost effectiveness for surgeons performing single-incision laparoscopic surgery. PMID:26576410

    Single-port laparoscopic cholecystectomy (LC) has been compared with 3- or 4-port LC. To our knowledge, there are no studies comparing the 3-, 2-, and 1-port techniques. Patients were randomized into 3 groups: LC 1-port using SILS, LC 2-port using a laparoscope with a working channel, and LC 3-port using the standard ports. Pain was evaluated at recovery, 4 hours, 24 hours, day 5, and day 8, using an analog visual scale. Homogenous groups in their demographic characteristics; all confirmed gallbladder lithiasis. At recovery, there was less pain in group 1 (P = 0.002); at 4 hours pain was similar in all groups (P = 0.899); at 24 hours there was less pain in groups 2 and 3 (P = 0.031); and at days 5 and 8 there was marginal (P = 0.053) and significant (P = 0.003) relevance. In terms of pain perception, LC performed through 1 port does not offer advantages when compared with 2 or 3 ports. More clinical trials are needed to confirm these data. PMID:25437581

    Purpose: To perform a retrospective outcomes analysis of central venous catheters with peripheral venous access ports, with comparison to published data.Methods: One hundred and twelve central venous catheters with peripherally placed access ports were placed under sonographic guidance in 109 patients over a 4-year period. Ports were placed for the administration of chemotherapy, hyperalimentation, long-term antibiotic therapy, gamma-globulin therapy, and frequent blood sampling. A vein in the upper arm was accessed in each case and the catheter was passed to the superior vena cava or right atrium. Povidone iodine skin preparation was used in the first 65 port insertions. A combination of Iodophor solution and povidone iodine solution was used in the last 47 port insertions. Forty patients received low-dose (1 mg) warfarin sodium beginning the day after port insertion. Three patients received higher doses of warfarin sodium for preexistent venous thrombosis. Catheter performance and complications were assessed and compared with published data.Results: Access into the basilic or brachial veins was obtained in all cases. Ports remained functional for a total of 28,936 patient days. The port functioned in 50% of patients until completion of therapy, or the patient's expiration. Ports were removed prior to completion of therapy in 18% of patients. Eleven patients (9.9% of ports placed) suffered an infectious complication (0.38 per thousand catheter-days)-in nine, at the port implantation site, in two along the catheter. In all 11 instances the port was removed. Port pocket infection in the early postoperative period occurred in three patients (4.7%) receiving a Betadine prep vs two patients (4.2%) receiving a standard O.R. prep. This difference was not statistically significant (p = 0.9). Venous thrombosis occurred in three patients (6.8%) receiving warfarin sodium and in two patients (3%) not receiving warfarin sodium. This difference was not statistically significant

  13. Use of fish larva morphometry to predict exclusion capabilities of small-mesh screens at cooling-water intakes

    SciTech Connect

    Schneeberger, P.J.; Jude, D.J.

    1981-03-01

    A relationship between total lengths and body depths of certain fish larvae was used to predict the effectiveness of small-mesh screens in limiting entrainment of fish larvae at cooling-water intakes. Total length-body depth regressions were linear for eight species (293 larvae) common to Lake Michigan near the J. H. Campbell Power Plant at Port Sheldon, Michigan. Regressions indicated that 35 to 100% (depending on species) of the fish larvae that had been entrained by the J. H. Campbell Plant in 1978 would have been excluded if 0.5-mm mesh screening had been employed in the plant's cooling water intake system instead of 9.5-mm bar mesh vertical traveling screens. These calculations do not take into consideration approach velocities of intake water, larva avoidance behavior, or mortality due to impingement on or extrusion through the screens.

    Today, the vast majority of electron storage rings delivering synchrotron radiation for general user operation offer a dedicated infrared port. There is growing interest expressed by various scientific communities to exploit the mid-IR emission in microspectroscopy, as well as the far infrared (also called THz) range for spectroscopy. Compared with a thermal (laboratory-based source), IR synchrotron radiation sources offer enhanced brilliance of about two to three orders of magnitude in the mid-IR energy range, and enhanced flux and brilliance in the far-IR energy range. Synchrotron radiation also has a unique combination of a broad wavelength band together with a well defined time structure. Thermal sources (globar, mercury filament) have excellent stability. Because the sampling rate of a typical IR Fourier-transform spectroscopy experiment is in the kHz range (depending on the bandwidth of the detector), instabilities of various origins present in synchrotron radiation sources play a crucial role. Noise recordings at two different IR ports located at the Swiss Light Source and SOLEIL (France), under conditions relevant to real experiments, are discussed. The lowest electron beam fluctuations detectable in IR spectra have been quantified and are shown to be much smaller than what is routinely recorded by beam-position monitors. PMID:22186638

  15. Reinforcement learning for port-hamiltonian systems.

    PubMed

    Sprangers, Olivier; Babuška, Robert; Nageshrao, Subramanya P; Lopes, Gabriel A D

    2015-05-01

    Passivity-based control (PBC) for port-Hamiltonian systems provides an intuitive way of achieving stabilization by rendering a system passive with respect to a desired storage function. However, in most instances the control law is obtained without any performance considerations and it has to be calculated by solving a complex partial differential equation (PDE). In order to address these issues we introduce a reinforcement learning (RL) approach into the energy-balancing passivity-based control (EB-PBC) method, which is a form of PBC in which the closed-loop energy is equal to the difference between the stored and supplied energies. We propose a technique to parameterize EB-PBC that preserves the systems's PDE matching conditions, does not require the specification of a global desired Hamiltonian, includes performance criteria, and is robust. The parameters of the control law are found by using actor-critic (AC) RL, enabling the search for near-optimal control policies satisfying a desired closed-loop energy landscape. The advantage is that the solutions learned can be interpreted in terms of energy shaping and damping injection, which makes it possible to numerically assess stability using passivity theory. From the RL perspective, our proposal allows for the class of port-Hamiltonian systems to be incorporated in the AC framework, speeding up the learning thanks to the resulting parameterization of the policy. The method has been successfully applied to the pendulum swing-up problem in simulations and real-life experiments. PMID:25167564

    1998-01-01

    The Physical Oceanographic Real-Time System (PORTS) provides observations of tides, tidal currents, and meteorological conditions in real-time. The San Francisco Bay PORTS (SFPORTS) is a decision support system to facilitate safe and efficient maritime commerce. In addition to real-time observations, SFPORTS includes a nowcast numerical model forming a San Francisco Bay marine nowcast system. SFPORTS data and nowcast numerical model results are made available to users through the World Wide Web (WWW). A brief overview of SFPORTS is presented, from the data flow originated at instrument sensors to final results delivered to end users on the WWW. A user-friendly interface for SFPORTS has been designed and implemented. Appropriate field data analysis, nowcast procedures, design and generation of graphics for WWW display of field data and nowcast results are presented and discussed. Furthermore, SFPORTS is designed to support hazardous materials spill prevention and response, and to serve as resources to scientists studying the health of San Francisco Bay ecosystem. The success (or failure) of the SFPORTS to serve the intended user community is determined by the effectiveness of the user interface.

    2015-01-01

    Port-site metastasis of prostatic adenocarcinoma is rare and usually associated with poor prognosis. We report a case of a young man with a rising prostate-specific antigen (PSA) 4.5 years after robot-assisted laparoscopic prostatectomy (RALP) and extended pelvic lymphadenectomy (ePLND) for a Gleason 7 (4+3) prostate cancer (pT3b pN0 cM0). Choline positron emission tomography-computed tomography (PET-CT) demonstrated a PET positive subcutaneous recurrence in a previous trocar site accompanied by a PET positive ipsilateral inguinal lymph node. Excision of both lesions was performed, confirming the diagnosis of metastatic prostate cancer. The patient's PSA dropped significantly postoperatively enabling postponement of androgen deprivation treatment up to this date. The etiology of port-site metastasis is multifactorial, including patient and surgery related factors. Such metastases have been scarcely reported following ePLND with or without RALP. Certain surgical precautions can be made to prevent the occurrence. We summarize previously reported mechanisms of development and possible precautionary measures. PMID:26225184

    The aim of this study is to analyze the current literature on single port radical prostatectomy (LESS-RP). Single port radical prostatectomy laparoendoscopic (LESS-RP) has established itself as a challenge for urological community, starting with the proposal of different approaches: extraperitoneal, transperitoneal and transvesical, initially described for laparoscopy and then laparoscopy robot-assisted. In order to improve the LESS-RP, new instruments, optical devices, trocars and retraction mechanisms have been developed. Advantages and disadvantages of LESS-RP are controversial, while some claim that it is a non-trustable approach, regarding the low cases number and technical difficulties, others acclaim that despite this facts some advantages have been shown and that previous described difficulties are being overcome, proving this is novel proposal of robotics platform, the Da Vinci SP, integrating the system into "Y". The LESS-RP approach gives us a new horizon and opens the door for rapid standardization of this technique. The few studies and short series available can be result of a low interest in the application of LESS-RP in prostate, probably because of the technical complexity that it requires. The new robotic platform, the da Vinci SP, shows that it is clear that the long awaited evolution of robotic technologies for laparoscopy has begun, and we must not lose this momentum. PMID:27072150

    1986-04-01

    Equivalent networks can be used in power system simulation to equipment or computer time and memory space. In this paper, an interative method is developed for synthesizing one-port equivalent networks by the removal of poles corresponding to resonances of the driving-point impedance or admittance function. This results in networks formed by the series or parallel connection of modular RLC circuits. The RLC values are calculated using a parameter-optimization technique. Multi-port equivalent networks are first configured as ..pi.. or T form composed of one-port network branches and the latters are then synthesized by the proposed method for one-port equivalent networks.

  2. Are Reductions in Population Sodium Intake Achievable?

    PubMed Central

    Levings, Jessica L.; Cogswell, Mary E.; Gunn, Janelle Peralez

    2014-01-01

    The vast majority of Americans consume too much sodium, primarily from packaged and restaurant foods. The evidence linking sodium intake with direct health outcomes indicates a positive relationship between higher levels of sodium intake and cardiovascular disease risk, consistent with the relationship between sodium intake and blood pressure. Despite communication and educational efforts focused on lowering sodium intake over the last three decades data suggest average US sodium intake has remained remarkably elevated, leading some to argue that current sodium guidelines are unattainable. The IOM in 2010 recommended gradual reductions in the sodium content of packaged and restaurant foods as a primary strategy to reduce US sodium intake, and research since that time suggests gradual, downward shifts in mean population sodium intake are achievable and can move the population toward current sodium intake guidelines. The current paper reviews recent evidence indicating: (1) significant reductions in mean population sodium intake can be achieved with gradual sodium reduction in the food supply, (2) gradual sodium reduction in certain cases can be achieved without a noticeable change in taste or consumption of specific products, and (3) lowering mean population sodium intake can move us toward meeting the current individual guidelines for sodium intake.

  3. Learning and memory in the Port Jackson shark, Heterodontus portusjacksoni.

    2014-03-01

    Basic understanding of the fundamental principles and mechanisms involved in learning is lacking for elasmobranch fishes. Our aim in this study was to experimentally investigate the learning and memory capacity of juvenile Port Jackson sharks, Heterodontus portusjacksoni. Sharks (N = 30) were conditioned over a 19-day period to associate an underwater LED light or stream of air-bubbles [conditioned stimulus (CS)] with a food reward [unconditioned stimulus (US)], using three procedures (delay, trace and control). During experiments, the CS signalled at a random time between 180 and 300 s for 30 s (six times per day). For the delay the US overlapped in time with the CS, for the trace the US delivered 10 s after the CS and for our control the US was delivered at random time between 180 and 300 s after the CS. H. portusjacksoni sharks trained in all procedures improved consistently in their time to obtain food, indicative of Pavlovian learning. Importantly, the number of sharks in the feeding area 5 s prior to CS onset did not change over time for any procedures. However, significantly more sharks were present 5 s after CS onset for delay for both air-bubble and light CS. Sharks trained in the delay and trace procedures using air-bubbles as the CS also displayed significantly more anticipatory behaviours, such as turning towards the CS and biting. Sharks trained with the light CS did not exhibit such behaviours; however, trace procedural sharks did show a significant improvement in moving towards the CS at its onset. At 20 and 40 days after the end of the conditioning experiments, some sharks were presented the CS without reward. Two sharks trained in the delay procedure using air-bubbles as the CS exhibited biting behaviours: one at 20 and the other at 40 days. This study demonstrates that H. portusjacksoni have the capacity to learn a classical conditioning procedure relatively quickly (30 trials during 5 days) and associate two time-separated events and

  19. Central Vein Dilatation Prior to Concomitant Port Implantation

    SciTech Connect

    Krombach, Gabriele A. Plumhans, Cedric; Goerg, Fabian; Guenther, Rolf W.

    2010-04-15

    Implantation of subcutaneous port systems is routinely performed in patients requiring repeated long-term infusion therapy. Ultrasound- and fluoroscopy-guided implantation under local anesthesia is broadly established in interventional radiology and has decreased the rate of complications compared to the surgical approach. In addition, interventional radiology offers the unique possibility of simultaneous management of venous occlusion. We present a technique for recanalization of central venous occlusion and angioplasty combined with port placement in a single intervention which we performed in two patients. Surgical port placement was impossible owing to occlusion of the superior vena cava following placement of a cardiac pacemaker and occlusion of multiple central veins due to paraneoplastic coagulopathy, respectively. In both cases the affected vessel segments were dilated with balloon catheters and the port systems were placed thereafter. After successful dilatation, the venous access was secured with a 25-cm-long, 8-Fr introducer sheath, a subcutaneous pocket prepared, and the port catheter tunneled to the venipuncture site. The port catheter was introduced through the sheath with the proximal end connected to a 5-Fr catheter. This catheter was pulled through the tunnel in order to preserve the tunnel and, at the same time, allow safe removal of the long sheath over the wire. The port system functioned well in both cases. The combination of recanalization and port placement in a single intervention is a straightforward alternative for patients with central venous occlusion that can only be offered by interventional radiology.

  16. Climate variability and Port wine quality

    Recent warming trends for Portugal have been found to be steepest in winter and spring and more pronounced for minimum than for maximum values of temperature (Miranda et al, 2002). These trends and associated changes in temperature and precipitation regimes may exert strong influences on agriculture systems. For instance, high values of the North Atlantic Oscillation (NAO) index have been shown to significantly reduce precipitation over Iberia and therefore induce low yield wheat crops in Portugal (Gouveia and Trigo, 2006). Port wine is produced from grapes grown in selected areas of the Douro valley, the so-called Região Demarcada do Douro, the first wine-producing region of the world (dating from 1758). A vintage wine is made from grapes that were grown and harvested in a single specified year and is classified as such because of the above average quality, a status that is attributed by Port houses in their best years. The Douro region presents distinctive climatic, topographic and soil characteristics. While the latest factors are fixed in time, the former may considerably change from year to year, exposing the Port wine productions to a large risk associated to interannual and intra-seasonal climatic variations. It is therefore to be expected that high quality wines are generally associated to optimum climatic conditions. In this work we have performed an analysis of the distinct behaviour of several meteorological fields in vintage versus non-vintage years. The relative importance of maximum and minimum temperature, precipitation and frost days is assessed for each individual month of the vegetative cycle and their importance to a high quality wine year is evaluated. Composites of 500 hPa geopotential height and sea level pressure fields over the Euro Atlantic region are also compared for vintage and non-vintage years. Results reveal a strong dependence of vintage production on maximum temperature and precipitation during spring and summer (the growing season

    Port wine stains are categorized as a benign capillary vascular malformation, which is hard to cure. In this paper, a photoacoustic microscopy system, which integrated a two-dimensional scanning galvanometer, an objective lens and a focused ultrasound transducer, was designed for noninvasive imaging of blood vessels of port wine stains model in vivo. Cock comb was chosen as the port wine stains model in the experiment. The blood vessels in x-y plane and x-z plane were imaged clearly. Experimental results demonstrate that photoacoustic microscopy can image the blood vessels of port wine stains model in vivo with high contrast and high resolution. It has the potential for clinical applications in detecting the blood vessels in port wine stains skin. PMID:22635179

    With over 360 ports of entry and 20 million sea, truck, and rail containers entering the United States every year, port facilities pose a large risk to security. Securing these ports and monitoring the variety of traffic that enter and leave is a major task. To accomplish this, the authors propose a fully distributed building block approach to port security. Based on prior work accomplished in the design and fielding of an intelligent transportation system in the United States, building blocks can be assembled, mixed and matched, and scaled to provide a comprehensive security system. Network blocks, surveillance blocks, sensor blocks, and display blocks will be developed and demonstrated in the lab, and at an inland port. The following functions will be demonstrated and scaled through analysis and demonstration: Barge tracking, credential checking, container inventory, vehicle tracking, and situational awareness. The concept behind this research is "any operator on any console can control any device at any time."

  20. Single-port approach to benign gynecologic pathology. A review.

    2015-06-01

    Laparoscopy is the gold standard in gynecological surgery. Single-port laparoscopic surgery, has been developed in order to improve minimally invasive surgery. We analyzed single-port approach in benign gynecologic pathology and made a bibliographic research on Pubmed and Medline from January 2000 to January 2015. From what emerges from the papers taken into consideration, single-port laparoscopy can be used for salpingostomy or salpingectomy to treat tubal ectopic pregnancy, benign adnexal disease (ovarian cystectomy, salpingo-oophorectomy), and for hysterectomy. We do not have enough data for complex procedures like myomectomy or hysteropexy. Robotic single-port laparoscopy seems to be a very attractive perspective and its use in benign gynecology surgery is expanding. More and more ergonomic limitations of single-port laparoscopy are corrected by development of articulated or flexible instruments and camera. Beyond these preliminary results, more ample prospective studies with an adapted and standardized instrumentation are thus essential to highlight real profits. PMID:25714874
