Collection and analysis of particulate from the DIII-D Tokamak  

International Nuclear Information System (INIS)

Particulate (i.e. tokamak dust) has been collected from the DIII-D tokamak located at General Atomics in San Diego, CA, USA. Two methods were used to collect particulate with the goal of preserving the particle size distribution and physical characteristics of the particulate. Vacuum collection on substrates and adhesion removal with metallurgical replicating tape were chosen as non-intrusive sampling methods. Sampling was completed in four toroidal locations of the machine; the 0-90 area, the 90-180 area, the 180-270 area, and the 270-360 area. The 0 direction designates the north side of the DIII-D machine. Four tiles in each area were sampled; the first vertical tile above the floor on the centerpost, a floor tile next to the center post, a tile on the isolated ring, and the first tile up from the isolated ring on the divertor. In addition, samples were collected from underneath the floor tiles at the 275 and the 75 locations. The count ...

Real-time management of water quality in the San Joaquin River Basin, California.  

Energy Technology Data Exchange (ETDEWEB)

In the San Joaquin River Basin, California, a realtime water quality forecasting model was developed to help improve the management of saline agricultural and wetland drainage to meet water quality objectives. Predicted salt loads from the water quality forecasting model, SJRIODAY, were consistently within +- 11 percent of actual, within +- 14 percent for seven-day forecasts, and with in +- 26 percent for 14-day forecasts for the 16-month trial period. When the 48 days dominated by rainfall/runoff events were eliminated from the data set, the error bar decreased to +- 9 percent for the model and +- 11 percent and +- 17 percent for the seven-day and 14-day forecasts, respectively. Constraints on the use of the model for salinity management on the San Joaquin River include the number of entities that control or influence water quality and the lack of a centralized authority to direct their activities. The lack of real-time monitoring sensors for ...

Variability of indicator values for ozone production sensitivity: a model study in Switzerland and San Joaquin Valley (California)  

International Nuclear Information System (INIS)

The threshold values of indicator species and ratios delineating the transition between NO_x and VOC sensitivity of ozone formation are assumed to be universal by various investigators. However, our previous studies suggested that threshold values might vary according to the locations and conditions. In this study, threshold values derived from various model simulations at two different locations (the area of Switzerland by UAM Model and San Joaquin Valley of Central California by SAQM Model) are examined using a new approach for defining NO_x and VOC sensitive regimes. Possible definitions for the distinction of NO_x and VOC sensitive ozone production regimes are given. The dependence of the threshold values for indicators and indicator ratios such as NO_y, O_3/NO_z, HCHO/NO_y, and H_2O_2/HNO_3 on the definition of NO_x and VOC sensitivity is discussed. Then the variations of threshold values under low emission conditions and in two different days are examined in ...

The Tropical East Pacific as a Laboratory for Tropical Cyclones  

Science.gov (United States)

The summertime tropical cyclogenesis rate per unit area in the eastern Pacific ocean is arguably higher than in any other location in the world. Many if not most of these cyclones form from African easterly waves which cross Central America into the Pacific. Of order 25% of these waves intensify into cyclones. A significant fraction of east Pacific tropical cyclones undergoes landfall on the Mexican coast. Those which do not, generally dissipate over cold ocean waters north of the east Pacific intertropical convergence zone, often not far from land. The layer of warm ocean water which supports the development of east Pacific cyclones is unusually shallow and is structured by anticyclonic vortices which form by various processes and propagate slowly to the west. These vortices locally deepen the oceanic mixed layer and support stronger convection than their surroundings, possibly promoting cyclogenesis and cyclone intensification. Cyclones in turn have an unusually large effect on ...

Development of 40m SANS and Its Utilization Techniques  

Energy Technology Data Exchange (ETDEWEB)

Small angle neutron scattering (SANS) has been a very powerful tool to study nanoscale (1-100 nm) bulk structures in various materials such as polymer, self assembled materials, nano-porous materials, nano-magnetic materials, metal and ceramics. Understanding the importance of the SANS instrument, the 8m SANS instrument was installed at the CN beam port of HANARO in 2001. However, without having a cold neutron source, the beam intensity is fairly low and the Q-range is rather limited due to short instrument length. In July 1, 2003, therefore, the HANARO cold neutron research facility project was launched and a state of the art 40m SANS instrument was selected as top-priority instrument. The development of the 40m SANS instrument was completed as a joint project between Korea Advanced Institute of Science and Technology and the HANARO in 2010. Here, we report the specification of a ...

The Reseau Education Sans Frontieres: reframing the campaign against the deportation of migrants  

British Library Electronic Table of Contents (United Kingdom)

This article analyses the emergence of the Reseau Education Sans Frontieres (RESF) in France, a movement that emerged in response to fear about the deportation of immigrant children who were pupils in French schools. Mobilising ethical concerns about children's welfare, the movement has been able to create public debate about the French State's moral responsibility to protect these children of 'sans-papiers'. Based on qualitative research, this article analyses the membership of RESF and its modes of action to show how this mobilisation has taken place, stressing the importance of 'everyday interactions' in this mobilisation, and the use of new frames of moral injustice concerning children's welfare.

Delayed Afterdepolarization in Intact Canine Sinoatrial Node as a Novel Mechanism for Atrial Arrhythmia  

British Library Electronic Table of Contents (United Kingdom)

Delayed Afterdepolarization in Sinoatrial Node. Introduction: Recent evidence indicates that spontaneous sarcoplasmic reticulum Ca release and Na-Ca exchanger current activation contribute to the sinoatrial node (SAN) automaticity. These findings suggest that SAN activity may share mechanisms that underlie both automaticity and triggered activity. The aim of this study is to test the hypothesis that spontaneous, nonvoltage gated, intracellular Ca (Cai) elevation may induce delayed afterdepolarization (DAD) in intact SAN during isoproterenol infusion. Methods and Results: We simultaneously mapped Cai and membrane potential in 31 isolated Langendorff-perfused canine right atriums (RA). Isoproterenol increased heart rate and late diastolic Cai elevation (LDCAE) of the superior SAN, leading to...

Data Center Energy Benchmarking: Part 4 - Case Study on aComputer-testing Center (No. 21)  

Energy Technology Data Exchange (ETDEWEB)

The data center in this study had a total floor area of 8,580 square feet (ft{sup 2}) with one-foot raised-floors. It was a rack lab with 440 racks, and was located in a 208,240 ft{sup 2} multi-story office building in San Jose, California. Since the data center was used only for testing equipment, it was not configured as a critical facility in terms of electrical and cooling supply. It did not have a dedicated chiller system but served by the main building chiller plant and make-up air system. Additionally, it was served by a single electrical supply with no provision for backup power. The data center operated on a 24 hour per day, year-round cycle, and users had all hour full access to the data center facility. The study found that data center computer load accounted for 23% of the overall building electrical load, while the total power consumption attributable to the data center including allocated cooling load and lighting was 30% of the total facility load. ...

Precise characterisation of nanochannels in track etched membranes by SAXS and SANS  

Energy Technology Data Exchange (ETDEWEB)

Poster session: Abstract is full text. Track membranes are thin polymer foils irradiated by heavy ions. The defects created by the heavy ions are located along the ions trajectory, the track. It is possible to open channels by etching with a chemical agent. These channels are very uniform. Small Angle Scattering (of X rays and neutrons) give global information about the characteristics of the channel shape. As the nanochannels are strictly parallel, an excellent sample orientation is required to obtain interpretable spectra. Then shoulders due to the oscillations of the Bessel function (radial part of the channel shape Fourier transform) are easily seen in the scattered intensity in the PXY data treatment software of SAS spectra allow to determine the channel diameter with its dispersion law, to demonstrate the existence of a wall thickness with a linearly varying density, and to assess the roughness. PXY can also detect non cylindric shapes like single or double cones or spindles. ...

Adaptive Waveform Correlation Detectors for Arrays: Algorithms for Autonomous Calibration  

Energy Technology Data Exchange (ETDEWEB)

Waveform correlation detectors compare a signal template with successive windows of a continuous data stream and report a detection when the correlation coefficient, or some comparable detection statistic, exceeds a specified threshold. Since correlation detectors exploit the fine structure of the full waveform, they are exquisitely sensitive when compared to power (STA/LTA) detectors. The drawback of correlation detectors is that they require complete knowledge of the signal to be detected, which limits such methods to instances of seismicity in which a very similar signal has already been observed by every station used. Such instances include earthquake swarms, aftershock sequences, repeating industrial seismicity, and many other forms of controlled explosions. The reduction in the detection threshold is even greater when the techniques are applied to arrays since stacking can be performed on the individual channel correlation traces to achieve significant array gain. In previous ...

The results of radon concentration measurements in the near surface air at San Nicolas Island, California, are presented for five different measurement sessions between May 1978 and July 1980. Emphasis is on the previously unreported results for January and July 1980. For six of eight days during the January session the measured radon concentration was greater than 40 picocuries per cm, corresponding to a continental air mass. Only the first day involved a maritime air mass with radon concentration less than about 6 picocuries per cm. In contrast to all the previous sessions, maritime air dominated the ten day session in July 1980, with radon concentrations generally less than about 5 picocuries per cm.

MAJOR OIL PLAYS IN UTAH AND VICINITY  

Energy Technology Data Exchange (ETDEWEB)

Utah oil fields have produced over 1.2 billion barrels (191 million m{sup 3}). However, the 13.7 million barrels (2.2 million m{sup 3}) of production in 2002 was the lowest level in over 40 years and continued the steady decline that began in the mid-1980s. The Utah Geological Survey believes this trend can be reversed by providing play portfolios for the major oil-producing provinces (Paradox Basin, Uinta Basin, and thrust belt) in Utah and adjacent areas in Colorado and Wyoming. Oil plays are geographic areas with petroleum potential caused by favorable combinations of source rock, migration paths, reservoir rock characteristics, and other factors. The play portfolios will include: descriptions and maps of the major oil plays by reservoir; production and reservoir data; case-study field evaluations; summaries of the state-of-the-art drilling, completion, and secondary/tertiary techniques for each play; locations of major oil pipelines; descriptions of reservoir ...

What can we learn about the lipid vesicle structure from the small-angle neutron scattering experiment? (Investigation DMPC vesicle structure by small angle neutron scattering)  

CERN Document Server

Small angle neutron scattering (SANS) on the unilamellar vesicle populations (diameter 500 and 1000 angstrom) was used to characterize lipid vesicles from dimyristoylphosphatidylcholine (DMPC) at three phases (gel, ripple, and liquid). Parameters of vesicle populations and internal structure of the DMPC bilayer were characterized on the basis of the Separated Form Factor (SFF) model. Parameters of the internal bilayer structure (thickness of the membrane and the hydrophobic core, hydration, and surface area of lipid molecule) were determined on the basis of the Hydrophobic-Hydrophilic (HH) approximation of neutron scattering length density across the bilayer r(x) and of the Step Function (SF) approximation of r(x). It was demonstrated in frame of HH approximation that DMPC membrane thickness in liquid phase (T=30 degrees) depends on the membrane curvature. The dependence of the DMPC membrane thickness on temperature was restored from the SANS ...

Toxic chemicals, including aromatic and chlorinated hydrocarbons and their derivatives, and liver lesions in white croaker (Genyonemus lineatus) from the vicinity of Los Angeles  

Energy Technology Data Exchange (ETDEWEB)

High concentrations of toxic chemicals in sediment and white croaker (Genyonemus lineatus), as well as liver diseases (e.g., carcinomas) in this species, were found in the Los Angeles area. The highest concentrations of aromatic hydrocarbons (AHs) in the sediment were in San Pedro Bay, and the highest concentrations of 1,1,1-trichloro-2,2-bis(p-chlorophenyl)ethane (DDT) derivatives were in sediment from near the White Point sewer outfall. Concentrations of AHs, polychlorobiphenyls (PCBs), and DDT derivatives were generally higher in food organisms from the croaker's stomach than in sediment. Moreover, croaker from San Pedro Bay and White Point were substantially contaminated with DDT derivatives and metabolites of aromatic compounds, compared to croaker from the Hyperion outfall and Dana Point. The evidence suggest that the observed pathological conditions of the liver were associated with exposure of the croaker to toxic chemicals, ...

However, since its definition in 1909, the age and depositional environment of this unit have been questioned. In 1971 in Pecos County, Vincent Kelly divided the unit into three members: Rio Bonito, Bonney Canyon, and Fourmile Draw. The lowest member, although named for the Rio Bonito, has a type section designated at Sunset along U.S. Highway 70/380. Two miles east of Sunset, near Riverside, on the Rio Bonito, the Rio Bonito Member is exposed in a long series of roadcuts. Petrographic investigation of these rocks reveals an alternating sequence of high to low-energy intertidal to subtidal facies marked by oolitic and fossiliferous dolocalcarenite interbedded with dolomitic mudstone. The unit has been recrystallized and stylolites are abundant, as is dolomite and nodular mosaic anhydrite. These ...

Baccharis Salicifolia development in the presence of high concentrations of uranium in the arid environment of San Marcos, Chihuahua  

International Nuclear Information System (INIS)

In humid zones and marine environments the bio indicator contaminants by trace elements are well established. However, in arid zones it is more difficult to find these tools because there is less biodiversity. The objective of this paper was to analyze the behavior of the Baccharis salicifolia plant in areas with high uranium concentration in arid zones, to determine the characteristics of tolerance and possible use as a bio monitor for the presence of such contaminants. For this project a uraniferous zone was selected in San Marcos, located northwest of the City of Chihuahua. A total of 8 sampling points of the plant and soil were located here. Each sample was divided into the root and the stem and leaves to determine the specific activity of the uranium in both parts of the plant and its sediments. The determination of the specific activities of the total uranium in the samples was obtained by liquid scintillation with alpha-beta separation. The results indicate ...

Dynamic stabilizer on-line experience  

Energy Technology Data Exchange (ETDEWEB)

A brief description is presented of the Westinghouse Torsional Dynamic Stabilizer, which was developed primarily as a countermeasure to ''torsional interaction'' subsynchronous resonance. Two such systems were installed and commissioned at the San Juan Generating Station, Waterflow, New Mexico in July, 1980. This paper describes the maintenance procedures and operating experience to date of these two units. The only known instance of operation at the high level bias point of the Stabilizer appears to indicate that the unit helped to dampen a turbine-generator shaft oscillation transient.

Ecological evaluation of proposed dredged material from Richmond Harbor Deepening Project and the intensive study of the Turning Basin  

Energy Technology Data Exchange (ETDEWEB)

Richmond Harbor is on the eastern shoreline of central San Francisco Bay and its access channels and several of the shipping berths are no longer wide or deep enough to accommodate modem deeper-draft vessels. The Water Resources Development Act of 1986 (PL99-662) authorized the US Army Corps of Engineers (USACE), San Francisco District to deepen and widen the navigation channels in Richmond Harbor. Several options for disposal of the material from this dredging project are under consideration by USACE: disposal within San Francisco Bay, at open-ocean disposal sites, or at uplands disposal sites. Purpose of this study was to conduct comprehensive evaluations, including chemical, biological, and bioaccumulation testing of sediments in selected areas of Richmond Harbor. This information was required by the Environmental Protection Agency (EPA) and USACE. Battelle/Marine Sciences Laboratory collected 20 core samples, both 4-in. ...

Use of semi-detailed kinetic schemes for a study of the temperature dependence in the reforming of fuels without catalyst; L'utilisation de schemas cinetiques semi-detailles pour une etude de l'influence de la temperature dans le reformage de combustibles sans catalyseur  

Energy Technology Data Exchange (ETDEWEB)

In order to avoid the use of catalysts in the process of auto-thermal reforming, it is possible to adopt a running at high temperature. In this study are presented the results of simulations of an auto-thermal/recuperator hybrid reforming system; these results are obtained with the oxidation model of alkanes developed by Ranzi and Faravelli. An isothermal configuration at high temperature improves the hydrogen yield and avoids the formation of soots. The analysis of the powers to be furnished to assure such an experimental mode, and the global approach of the fuel cell system show that the management of the heat exchanges is a key parameter in this process.

Technical evaluation report for the demonstration of radio frequency soil decontamination at Site S-1  

Energy Technology Data Exchange (ETDEWEB)

The Air Force`s Armstrong Laboratory at Tyndall Air Force Base, Florida, has supported the research and development of Radio Frequency Soil Decontamination. Radio frequency soil decontamination is essentially a heat-assisted soil vapor extraction process. Site S-1 at Kelly Air Force Base, San Antonio, Texas, was selected for the demonstration of two patented techniques. The site is a former sump that collected spills and surface run-off from a waste petroleum, oils, and lubricants and solvent storage and transfer area. In 1993, a technique developed by the IIT Research Institute using an array of electrodes placed in the soil was demonstrated. In 1994, a technique developed by KAI Technologies, Inc. using a single applicator placed in a vertical borehole was demonstrated. Approximately 120 tons of soil were heated during each demonstration to a temperature of about 150 degrees Celsius.

Numerical Simulation of a Polymer electrolyte Fuel Cell; Simulacion Numerica de una Pila de combustible de Membrana Polimerica  

Energy Technology Data Exchange (ETDEWEB)

This document reproduces the final project of David San Fabian Ayuso, presented on May 26, 2005, for the obtention of the engineer degree of the Carlos III University of Madrid. A single-phase, isothermal model, including both electron and proton transport, is introduced for the simulation of polymer electrolyte fuel cells (PEM). The model is implemented in the commercial code Fluent 6.0, through the use of UDFs (User Defined Functions). In order to validate the model, a single canal of a PEM monocell is simulated in three dimensions. The obtained result are qualitatively satisfactory. It is observed that it is not essential to solve the current collectors when a monocell is considered (and not a stack). in the present study, the number of nodes is the computational grid appears to be too low in the membrane zone in order to make a complete validation of the model.

Dynamics of photosynthetic photon flux density (PPFD) and estimates in coastal northern California  

British Library Electronic Table of Contents (United Kingdom)

Plants require solar radiation for photosynthesis and their growth is directly related to the amount received, assuming that other environmental parameters are not limiting. Therefore, precise estimation of photosynthetically active radiation (PAR) is necessary to enhance overall accuracies of plant growth models. This study aimed to explore the PAR radiant flux in the San Francisco Bay Area of northern California. During the growing season (March through August) for 2?years 2007?2008, the on-site magnitudes of photosynthetic photon flux densities (PPFD) were investigated and then processed at both the hourly and daily time scales. Combined with global solar radiation (R S) and simulated extraterrestrial solar radiation, five PAR-related values were developed, i.e., flux density-based PAR ...

Third phase formation in the extraction of phosphotungstic acid by TBP in n-octane  

International Nuclear Information System (INIS)

The solvent extraction of 12-phosphotungstic acid, also known as 12-tungstophosphoric acid-H_3PW_1_2O_4_0, the so-called Keggin heteropolyacid - by 0.73 M (20%v/v) tri-n-butyl phosphate (TBP) in n-octane under conditions comparable to those used previously for the extraction of conventional inorganic mineral acids is described. A simplified phase diagram for the pentanary system comprised of H_3PW_1_2O_4_0, HNO_3, H_2O, TBP, and n-octane reveals an extremely low initial concentration of H_3PW_1_2O_4_0 (1.1 mM) at the LOC (limiting organic concentration) condition, far lower than the most effective third-phase-forming inorganic acid, namely HClO_4. The results from small-angle neutron scattering (SANS) indicate that the interparticle attraction energy - U(r) calculated through application of the Baxter sticky sphere model to the SANS data at the LOC condition - does not approach the -2 k_B T value associated with phase splitting in previous ...

Shallow subsurface temperatures and some estimates of heat flow from the Colorado Plateau of northeastern Arizona  

Energy Technology Data Exchange (ETDEWEB)

Temperature data to depths of a few hundred meters were obtained from 29 wells in northeastern Arizona; 12 in the region surrounding the San Francisco Volcanic Field, 8 in the Black Mesa area, and 9 in the south-central Colorado Plateau which includes the White Mountains. Although there was evidence for local hydrologic disturbances in many temperature profiles, most wells provided an estimate of the conductive thermal gradient at the site. A few thermal conductivities were measured and were combined with published regional averages for the north-central part of the Colorado Plateau to produce crude estimates of regional heat flux. None of the wells was accessible below the regional aquifers. To these depths, heat flow in the area of the San Francisco Volcanic Field appears to be controlled primarily by regional lateral water movement having a significant downward vertical component of velocity. The mean heat flow of 27 +- 5 mWm/sup -2/ is only ...

Petroleum potential of southern Hispaniola  

Energy Technology Data Exchange (ETDEWEB)

The island of Hispaniola (Dominican Republic and Haiti) lies within the North Caribbean strike-slip plate boundary zone. The post-Eocene history of Hispaniola is marked by strike-slip accretion of crustal fragments onto a Late Cretaceous-Eocene island arc. Three onshore Neogene clastic basins have been the focus of petroleum exploration in Hispaniola. Oil production was achieved by drilling surface anticlines in the Azua Basin in South-Central Hispaniola (Dominican Republic) during World War II (Maleno and Higuerito fields). More modern seismic exploration has been carried out in the Enriquillo, San Juan and Cibao Basins, but has not resulted in production. Recent surface and seismic stratigraphic mapping has elucidated the geologic history of Southern Hispaniola. It consists of several Late Cretaceous-Eocene oceanic and island-arc terranes separated by E-W to NW/SE-striking ''ramp'' or thrust-bound clastic basins of Neogene age ...

Isotope and trace element systematics in a spinel-lherzolite-bearing suite of basanitic volcanic rocks from San Luis Potosi, Mexico  

Energy Technology Data Exchange (ETDEWEB)

Lherzolite-bearing basanitic magmas of Quaternary age have erupted to form maars, lava/cinder cones and lava flows in two volcanic fields (Ventura and Santo Domingo) in the central Mexican state of San Luis Potosi. The systematics of the radiogenic isotopes of Sr, Nd, and Pb and the relationship between these parameters and elemental compositions are used to investigate the petrogenesis of the volcanic rocks and the nature of their mantle sources. Sr and Nd isotopic data are presented for 19 basanitic rocks, 5 kaersutites, and 6 lherzolitic xenoliths; Pb data presented for the same 19 volcanic rocks and 4 of the 5 kaersutites. The isotopic compositions for all of these samples fall within the mantle range defined by MORBs and OIBs. The basanites generally plot within the OIB field on isotopic diagrams; most of the kaersutites are displaced to slightly more-depleted (i.e. MORB-like) values than the volcanic samples and the xenoliths, with one exception, are ...

Geology of 1. 7 GA ( ) Baldwin gneiss in the Baldwin Lake type area, San Bernardino Mountains, southern California  

Science.gov (United States)

Precambrian gneisses in the San Bernardino Mountains were first identified and described in the vicinity of Baldwin Lake by Guillou (1953). Five lithologic units mappable at 1:24,000 scale are recognized: biotite [+-] muscovite quartzofeldspathic gneiss, amphibolite, pyroxene metagabbro, augen gneiss, and biotite [+-] muscovite granitic gneiss. Baldwin gneiss with this L Baldwin Lake, the gneissic fabric is rotated toward the northwest, subparallel to the Doble fault. Along this fault, Baldwin gneiss is structurally underlain by overturned Paleozoic quartzite and marble (Zabriskie Quartzite and Carrara Formation). Regional relations suggest that the Doble fault is a northeast-directed basement thrust fault of pre-Late Cretaceous age, and may be contemporaneous with late Paleozoic deformation and metamorphism of Paleozoic rocks further west in the range. Field relations suggest that Baldwin gneiss in its type area largely retains Proterozoic fabrics and mineral ...

Aerosol Physical, Optical and Chemical Properties during African Dust Events at Cape San Juan (CPR)  

Science.gov (United States)

Large amounts of atmospheric dust are lifted from the North African deserts and are transported by the trade winds over the Caribbean region, especially during the summer months. How African dust particles influence the earth's radiative budget is not well understood because these particles are highly variable and their physical, optical, and chemical properties are poorly characterized, especially when they are atmospherically processed as are those that travel from Africa to the Caribbean region. Here we present results of aerosol measurements performed at Cape San Juan (CPR), a ground-based station located at the northeastern tip of the Caribbean island of Puerto Rico. We used a condensation particle counter to determine the particle number concentration, a sunphotometer (part of the AErosol RObotical NETwork, AERONET, aeronet.gsfc.nasa.gov) to determine volume size distributions and aerosol optical thickness, and a 3-wavelength nephelometer and ...

Acoustic and visual remote sensing of barrels of radioactive waste: Application of civilian and military technology to environmental management of the oceans  

Energy Technology Data Exchange (ETDEWEB)

As part of an ongoing strategic research project to find barrels of radioactive waste off San Francisco, the U.S. Navy (USN), the U.S. Geological Survey (USGS), and the Gulf of the Farallones National Marine Sanctuary (GFNMS) pooled their expertise, resources, and technology to form a partnership to verify new computer enhancement techniques developed for detecting targets the size of 55 gallon barrels on sidescan sonar images. Between 1946 and 1970, approximately 47,800 large barrels and other containers of radioactive waste were dumped in the ocean west of San Francisco; the containers litter an area of the sea floor of at least 1400 km {sup 2} knows as the Farallon Island Radioactive Waste Dump. The exact location of the containers and the potential hazard the containers pose to the environment is unknown. The USGS developed computer techniques and contracted with private industry to enhance sidescan data, collected in cooperation with the ...

The Third US Naval Observatory CCD Astrograph Catalog (UCAC3)  

CERN Document Server

The third US Naval Observatory (USNO) CCD Astrograph Catalog, UCAC3 was released at the IAU General Assembly on 2009 August 10. It is the first all-sky release in this series and contains just over 100 million objects, about 95 million of them with proper motions, covering about R = 8 to 16 magnitudes. Current epoch positions are obtained from the observations with the 20 cm aperture USNO Astrograph's "red lens", equipped with a 4k by 4k CCD. Proper motions are derived by combining these observations with over 140 ground- and space-based catalogs, including Hipparcos/Tycho and the AC2000.2, as well as unpublished measures of over 5000 plates from other astrographs. For most of the faint stars in the Southern Hemisphere the Yale/San Juan first epoch plates from the SPM program (YSJ1) form the basis for proper motions. These data are supplemented by all-sky Schmidt plate survey astrometry and photometry obtained from the SuperCOSMOS project, as well as 2MASS near-IR ...

Preliminary results from an advanced lighting controlstestbed  

Energy Technology Data Exchange (ETDEWEB)

Preliminary results from a large-scale testbed of advanced lighting control technologies at the Phillip Burton Federal Building at 450 Golden Gate Ave. in San Francisco are presented. The first year objective of this project is to determine the sustainable energy savings and cost-effectiveness of different lighting control technologies compared to a portion of the building where only minimal controls are installed. The paper presents the analyzed results from six months of tests focused on accurately characterizing the energy savings potential of one type of daylight-linked lighting controls compared to the lighting in similar open-planned areas without dimming controls. After analyzing a half year;s data, we determined that the annual energy savings for this type of daylight- linked controls was 41% and 30% for the outer rows of lights on the South and North sides of the building, respectively. The annual energy savings dropped to 22% and 16% for the second row of ...

Molecular epidemiology of childhood leukemia with emphasis on chemical exposures  

Energy Technology Data Exchange (ETDEWEB)

Developing markets in the Pacific Basin depend heavily on the production and export of consumer goods. The generation of hazardous waste as a by-product of industrial production can be linked to adverse health outcomes, such as childhood leukemia, in ways that are presently unknown. In California, exposures resulting from hazardous waste disposal are of concern in the etiology of childhood cancer. Approximately 63% of the 57 hazardous waste sites that the U.S. Environmental Protection Agency (USEPA) included in the national priority list under the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) statute were in the six-county San Francisco Bay area. This area includes California`s Silicon Valley, where a disproportionate majority of these sites are located. Although only one study links hazardous waste disposal to childhood leukemia evidence is accumulating that in utero and maternal pesticide exposures as well as chemical exposures ...

Leaching characterization of red mud. Sekidei no 2,3 no san ni yoru shinshutsu  

Energy Technology Data Exchange (ETDEWEB)

The study to get some fundamental materials was carried out, aiming at the recovery of valuable components from red mud produced in the bauxite processing. Acid leaching of red mud was used to clarify the effect of leaching time, leaching temperature and acid concentration on the recovery. The used acids were hydrochloric acid, sulfuric acid and nitric acid of which concentrations were 1.45, 1.8 and 1.2mol-l; the temperature was 25, 40 and 60 centigrade; and the time was 1, 2, 4 and 8 hours. Al in red mud was leached by all acids, became the equilibrium after 10 minutes, and was independent og the temperature and the leaching rate was about 70%. When the acid concentration was raised to two time for sulfuric acid and hydrochloric acid, the leaching rate increased by 15%. Si showed the same tendency as Al and the leaching rate was about 65%, but the decrease of 15% was confirmed by raising the concentration of sulfuric acid to two times. The leaching rate of Fe increased greatly along ...

Innovative geographically-targeted time-of-use rate making  

Energy Technology Data Exchange (ETDEWEB)

Pacific Gas & Electric Co.`s (PG&E`s) Delta district, approximately 45 miles northeast of the San Francisco Bay Area, is a fast growing residential community with peak demand occurring between 6 and 7 PM in hot summer weekdays. In the early 1990s, PG&E`s system planners projected a need to build a new substation in 1996 to meet the local peak electricity demand. In 1991, as part of a new distribution planning and capital investment process, PG&E launched its innovative Model Energy Community (MEC or Delta) program to test whether the inclusion of new, experimental rates and geographically-targeted cost-effective energy-efficiency measures could reduce the local peak demand and therefore defer major substation and T&D capital investment. Two new residential TOU rates were designed and implemented in PG&E`s Delta area between 1991 and 1993. This paper discusses the market assessment activities and results for these rates, focusing on the ATOU ...

Genetic control of cotton insects: The pink bollworm as a working programme  

International Nuclear Information System (INIS)

Establishment of a continuous population has been prevented over a 24 year period in the San Joaquin Valley, USA, through continuous, daily in-season release of sterile pink bollworms based on an extensive trap monitoring programme. A post-harvest crop destruction ordinance and occasional use of pheromones as disruptants were the only other factors used by programme management, except in 1990. In 1990, the programme used a conventional insecticide on 280 acres (113 ha) out of 1.18 million acres (477,546 ha) of cotton. During the four year period 1986-1989, a management system was explored using a high rate pheromone disruption system and sterile insects. Major reductions in conventional insecticide usage, while maintaining extremely low populations, were evident in this semi-isolated valley of southern California. It is hoped that this will provide a model for a future large scale test on up to 20,000 acres (8100 ha) of cotton. (author). 11 refs, 1 fig., 7 tabs.

Blood pressure and blood lead concentration in bus drivers  

Energy Technology Data Exchange (ETDEWEB)

San Francisco bus drivers have an increased prevalence of hypertension. This study examined relationships between blood lead concentration and blood pressure in 342 drivers. The analysis reported in this study was limited to subjects not on treatment for hypertension (n = 288). Systolic and diastolic pressure varied from 102 to 173 mm Hg and from 61 to 105 mm Hg, respectively. The blood lead concentration varied from 2 to 15 ..mu..g/dL. The relationship between blood pressure and the logarithm of blood lead concentration was examined using multiple regression analysis. Covariates included age, body mass index, sex, race, and caffeine intake. The largest regression coefficient relating systolic blood pressure and blood lead concentration was 1.8 mm Hg/ln (..mu..g/dL). The coefficient for diastolic blood pressure was 2.5 mm Hg/ln (..mu..g/dL). These findings suggest effects of lead exposure at lower blood lead concentrations than those concentrations that have ...

Computed tomograms of the newborn  

International Nuclear Information System (INIS)

Computed tomograms (CT) from 204 cases of premature and full term infants were studied. 1) In 70 infants of hyaline membrane disease, primary apnea and asymptomatic transient hypoglycemia and hypocalcemia, without any abnormal CT findings such as intracranial hemorrhage, periventricular lucency was found in 65 cases (93%) and a wide extracerebral space of the temporal lobes was found in 60 cases (86%) before 44 weeks of gestation. A wide interhemispheric fissure was found in 11 cases of extremely premature infants before term. Periventricular lucency and a wide extracerebral space of temporal lobes may not be the result of the intracranial pathological changes, but they may represent a stage of brain development. 2) In 204 cases, intracranial hemorrhage was found in 39 cases; intra ventricular 14 cases, subependymal 2 ...

Computed tomographic findings of intrahepatic peripheral cholangiocarcinoma  

International Nuclear Information System (INIS)

Cholangiocarcinoma is synonymous with bile duct carcinoma, and can originate in a small intrahepatic bile duct (peripheral type), a major intrahepatic duct including the hepatic hills, an extrahepatic duct, or near the papilla of Vater (central type). In a sense bile duct carcinoma of the peripheral type is cholangiocarcinoma of the liver; it has the same gross configuration as hepatocellular carcinoma, resulting in difficulty to differentiate on the CT. The authors studied CT findings of 14 cases of pathologically proven peripheral type cholangiocarcinoma of the liver during the last 4 years. The results were as follows: 1. Of 14 cases, 8 were female and 6 were male, and the age ranged from 5th to 7th decades. 2. Preoperative clinical diagnosis were as follows: hepatoma 8 cases, abscess 5 cases and metastasis 1 case in order of frequency. 3. Diagnosis were confirmed by hepatic ...

Relationship between serum heat-stable alkaline phosphatase level and pregnancy  

International Nuclear Information System (INIS)

Serum heat-stable alkaline phosphatase (HSAP) level in 649 cases of normal pregnancy and 164 cases of high-risk pregnancy is measured by radioimmunoassay (RIA). The results indicate that the HSAP level in normal pregnancy increased proportionally with gestation weeks (r = 0.9843). In 33 cases of pregnancy induced hypertension and 21 cases of intrauterine fetal growth retardation, the HSAP level is significantly low. In 7 cases of neonatal asphyxia and 26 cases of fetal distress, the HSAP level in the mother's serum is also low. In 53 cases of intrahepatic cholestasis of pregnancy, the HSAP level is similar to those of normal pregnancy. This study illustrates that HSAP RIA can play an important role in the evaluation of placental function and fetal prognosis for cases of high-risk pregnancy.

Laparoscopy and intersex: report of 5 cases of male pseudohermaphroditism.  

Science.gov (United States)

From May, 1999 to August, 2006, we performed laparoscopic diagnosis and treatment for 103 cases of impalpable testes. Among those we found 5 cases of male pseudohermaphroditism of different etiologies. Three males presented by impalpable testes with ambiguous genitalia and 2 females presented by primary amenorrhea. All of them have 46-XY normal male chromosomal pattern. In the first 3 cases, the etiology was complete gonadal dysgenesis, and 2 cases with persistent Mullerian syndrome. Timed gonadectomy for the first case and laparoscopic orchiopexy for the other 2 cases were performed. For the other 2 female cases, the etiology was complete androgen insensitivity syndrome and laparoscopic bilateral orchiectomy was performed for both of them. All the procedures were done without complications with satisfactory results. PMID:18319558

Use of SPOT satellite imagery to obtain GIS input for oil spill models  

Energy Technology Data Exchange (ETDEWEB)

Satellite imagery is a cost-effective tool for creating and updating basemaps of coastal zones, especially where existing maps and aerial photographs are unavailable, are out-of-date, or provide limited information. Reliable maps of coastal zones are particularly important for oil spill modelling programs. Color IR (multispectral) images with 20m x 20m ground resolution and black & white (panchromatic) images with 10m x 10m ground resolution of many coastlines around the globe have been acquired from 1986 to present by SPOT Image Corporation. We have digitally merged same-day SPOT panchromatic and multispectral imagery to provide maximum spatial resolution and permit excellent color differentiation of coastal zone features. This combination adequately discriminates individual features, including pipelines, offshore platforms, storage tanks, jetties, and shoreline type. The SPOT images were interpreted within a workstation environment and the coastline interpretation map (a digital ...

Understanding the distribution and architecture of algal mound reservoirs through outcrop-based high-resolution sequence stratigraphy: An example from the paradox basin, USA  

Energy Technology Data Exchange (ETDEWEB)

An outcrop-based study combining detailed lithofacies analysis with high-resolution sequence stratigraphy in the Paradox Basin, southwestern United States. has shown that complex lateral and vertical facies variations occur in relatively consistent and predictable patterns. Large-scale facies shifts of several kilometers occur across major sequence boundaries whereas small-scale lateral and vertical variations develop from stacking of individual cycles. Understanding of vertical stacking patterns and lateral distribution of facies in outcrop can be directly applied to both three-dimensional distribution of reservoir facies in the subsurface as well as the evaluation of heterogeneity within individual reservoirs. The Desert Creek and Ismay intervals of the Paradox Formation (Pennsylvanian) exposed along the San Juan River in southeastern Utah are characterized by high-frequency cyclic repetition of carbonate and siliciclastic facies controlled primarily by 4th and ...

The China Clipper - fast advective transport of radon-rich air from the Asian boundary layer to the upper troposphere near California  

Energy Technology Data Exchange (ETDEWEB)

A series of upper tropospheric radon concentration measurements made over the eastern Pacific and west coast of the United States during the summers of 1983 and 1984 has revealed the occurrence of unexpectedly high (>16 pCi/SCM) radon concentrations for 9 of the 61 measurements (and 6 of the 13 flights). A frequency distribution plot of the set of 61 observations shows a distinct bimodal distribution, with approximately 2/5 of the observations falling close to 1 pCi/SCM, and 3/5 falling in a high concentration mode centered at about 11 pCi/SCM. Trajectory and synoptic analyses for two of the flights on which such high radon concentrations were observed indicate that this radon-rich air originated in the Asian boundary layer, ascended in cumulus updrafts, and was carried eastward in the fast moving air on the anti-cyclonic side of the upper tropospheric jet. Transit times were of the order of 3 days; however, in one instance, transport from China to a point a few hundred kilometers ...

THE EVOLUTION OF THE KINEMATICS OF NEBULAR SHELLS IN PLANETARY NEBULAE IN THE MILKY WAY BULGE  

International Nuclear Information System (INIS)

We study the line widths in the [O III]#lambda#5007 and H#alpha# lines for two groups of planetary nebulae in the Milky Way bulge based upon spectroscopy obtained at the Observatorio Astronomico Nacional in the Sierra San Pedro Martir (OAN-SPM) using the Manchester Echelle Spectrograph. The first sample includes objects early in their evolution, having high H#beta# luminosities, but [O III]#lambda#5007/H#beta# < 3. The second sample comprises objects late in their evolution, with He II #lambda#4686/H#beta#>0.5. These planetary nebulae represent evolutionary phases preceding and following those of the objects studied by Richer et al. in 2008. Our sample of planetary nebulae with weak [O III]#lambda#5007 has a line width distribution similar to that of the expansion velocities of the envelopes of asymptotic giant branch stars and shifted to systematically lower values as compared to the less evolved objects studied by Richer et al. The sample with strong He II ...

Probabilistic endowment appraisal system based upon the formalization of geologic decisions. National Uranium Resource Evaluation. Final report: demonstration and comparative analysis of estimates and methods  

Energy Technology Data Exchange (ETDEWEB)

This report is the culmination of approximately three and one-half years of research on the design and demonstration of a mineral endowment appraisal system which has as its foundation a formalization of geological decisions within a probabilistic framework. Basically, the probabilistic decision structure of a geologist or team of geologists is captured in a system of computer programs which can be used by a geologist for the estimation of the magnitude of uranium endowment by providing information to this system about the states of earth processes and geologic conditions that pertain to that region being evaluated. Research performed under this contract had two main objectives: demonstration of the endowment appraisal system on the San Juan Basin of New Mexico; a comparison of estimates by the appraisal system with estimates made using other methodologies. The scope of this report is restricted to a demonstration of the appraisal system and the comparison of ...

Natural resource injury assessment of a crude oil spill  

International Nuclear Information System (INIS)

In January 1994, a 6.7 magnitude earthquake in southern California ruptured a pipeline releasing approximately 4,200 barrels of blended San Joaquin Valley crude oil. A smaller volume entered the Santa Clara River and flowed 25 km downstream to an emergency containment dam. Ruptured water mains and chlorinated discharges from a damaged sewage treatment plant also affected water quality in the river. Quantitative injury assessment studies were initiated within days of the spill and included water/sediment chemistry, benthic macroinvertebrate community analyses and aquatic toxicity tests. Water quality values for TPH, BTEX, and chlorine ranged from nondetectable to 78 mg/l (TPH), nondetectable to 5.4 microg/l (total BTEX constituents) and nondetectable to 600 microg/l (residual chlorine) within 72 hours of the spill. Ammonia concentrations ranged from nondetectable to 12.1 mg/l within 10 days of the spill. Hydrocarbon concentrations in sediments ranged from ...

Experiments in High-Frequency Imaging of the 2004 M6.0 Parkfield Earthquake  

Science.gov (United States)

We attempt to image the rupture propagation of the 2004 M6.0 Parkfield earthquake by analyzing records from the USGS Parkfield seismic array (UPSAR) and other strong-motion stations. The UPSAR array consists of 12 stations distributed over about one square kilometer at a distance of 10~km from the San Andreas fault near Parkfield, California. We employ a method that uses reverse time migration to stack the seismograms at back-projected locations along the fault. We use waveform cross-correlation to align the initial P-wave arrivals and correct for small static time shifts in the records. This forces a coherent image at the hypocenter at the quake origin time. Initial results at later time steps show some evidence of the expected rupture propagation to the north. However, the resolution of the back-projection is limited by the small aperture of the UPSAR array. Records from other strong-motion stations can improve the theoretical resolution kernels but are less ...

Effects of pork/beef levels and various casings on quality properties of semi-dried jerky  

British Library Electronic Table of Contents (United Kingdom)

The aim of this study was to investigate the effects of pork/beef levels and the casings on the quality properties of semi-dried jerky. The pork/beef levels in the four test formulations were as follows: T-1 (pork: beef=100:0), T-2 (95:5), T-3 (90:10), and T-4 (80:20). After tumbling for 30min with curing solution, the cured meats were stuffed into natural sheep casings, collagen casings, or cellulose casings, and then dried. The restructured jerky with cellulose casing had the lowest water content and the highest protein content, with no significant differences between various formulations. There were no significant differences among all formulations with regard to pH and total microbial counts, and jerky with cellulose casing had the lowest value of water activity. The processing yields ...

The usefulness of CBF brain SPECT in forensic medicine: the civil law codes cases. A description of four cases  

International Nuclear Information System (INIS)

The aim of this report was to assess the usefulness of cerebral blood flow (CBF) scanning utilising the SPECT technique in forensic medicine cases in the area of civil law cases. CBF SPECT scanning was performed in four patients utilising "9"9"mTc-ECD and a triple-head gammacamera. In the analysis both the asymmetry index and cerebellar normalisation were applied. Reference values were obtained by studying 30 healthy volunteers. In those cases CBF SPECT scanning played an important role in forensic argument. It influenced the sentence and the amount of financial compensation. CBF SPECT scanning may provide valuable information in forensic medicine argument in civil law cases, but only when taken together with psychometric tests and other neuroimaging methods (CT, MRI). The value of CBF SPECT scanning alone may be limited in judicial proceedings. (author)

DNA barcoding as a tool for species identification in three forensic wildlife cases in South Africa  

British Library Electronic Table of Contents (United Kingdom)

Poaching of wildlife animals for subsistence and commercial purposes has lead to population declines in Africa. In forensic cases, a need exists to identify the species of origin of carcasses, meat or blood. In the study presented here, the mitochondrial COI gene was sequenced to determine the species of unknown samples in three suspect South African forensic wildlife cases. In two cases the unknown samples were identified as originating from domestic cattle (Bos taurus) and in the third case the sample was identified as common reedbuck (Redunca arundinum). This is the first report of the COI sequence of common reedbuck. The study highlights the need for accurate wildlife reference material from each country in order to convict wildlife cases.

British Library Electronic Table of Contents (United Kingdom)

Cellulose sausage cellulose casings are used extensively in the manufacture of sausages in meat packaging. After stripping the meat, spent casings mainly contain cellulose and residual meat juice with salt, nitrate and nitrite. Disposal of spent sausage casings has serious economic and environmental concerns for the sausage industry. This work describes bioconversion of spent cellulose casings (SCC) into enzymes, lactic acid and ethanol by using cellulolytic fungi, lactobacillus and yeasts. The solid substrate cultivation (SSC) of Trichoderma reesei RUT C-30 on SCC and blends gave a maximum of 152 filter paper cellulase (FPase) activity and about 100 carboxymethylcellulase activity (CMCase)/g dry weight substrate. The SSC produced enzyme-rich casing with 50 FPase when directly mixed as suc...

Radiation therapy for Kasabach-Merritt syndrome. Analysis of unfavorable factors in 5 children  

Energy Technology Data Exchange (ETDEWEB)

During the past 10 years, five infants with Kasabach-Merritt syndrome (K-M) receiving radiation therapy were reported. We investigated whether radiation therapy for K-M was useful and what the unfavorable factors of K-M were. During the past 10 years, we have treated five infants with K-M. The syndrome occurred at ages ranging from birth to 4 months. The incidence of female to male ratio was 3:2. Among 5 cases, the site of hemangioma was as follows; shoulder, anterior chest wall, lower abdominal wall, face and neck and inguinal site. All 5 cases received medication to control the coagulopathy including prednisone and blood transfusion at first. Because the platelet count and the bleeding tendency did not improve in any case, these cases received radiation therapy. Total dose ranged from 5 to 10 Gy and fraction-size ranged from 0.5 to 1.75 Gy. Irradiation session was 2 or 3 times per week. In 5 ...

For early diagnosis of the fracture healing, nonunion and avascular necorsis  

Energy Technology Data Exchange (ETDEWEB)

Complications of non-union and avascular necrosis during fracture healing process are the most important problems. Early detection of the evidence of non-union and avascular necrosis and follow-up study of fracture healing process will reduce complications and sequellae in fracture patients. Femoral neck and tibial shaft are the most important fracture sites where non-union and/or avascular necorsis are frequently developed. Osteomedullography was performed in 30 cases of fracture, 21 femoral neck, 8 tibial shafts and 1 talar neck, in the Department of Radiology of national Medical Center during the period form August 1977 to March 1981. The following results were obtained: 1. 16 patients of femoral neck fracture were performed osteomedullography one. Non-union showing no crossing vein through the fracture site was noted in 12 cases from 16 patients. 4 cases from the 12 patients of non-union showed decreased viability but 2 ...

Program NetMoment; Simultaneous Calculation of Moment, Source Corner Frequency, and Site Specific t* from Network Recordings  

Energy Technology Data Exchange (ETDEWEB)

The purpose of computer program NetMoment (Appendix I) is to utilize fundamental knowledge of earthquake sources, propagation attenuation, and site response in a simultaneous inversion of network data to determine the moment and source corner frequency of earthquakes, and site specific t*. The source parameters are especially difficult to determine for small earthquakes. A fundamental problem in determining the source corner frequencies of small earthquakes is that site response can result in spectral corner frequencies in the range that may be expected from the earthquakes themselves. Several authors have identified this as fmax (Hanks, 1982), a constant corner frequency for small events so that below threshold moment (about 1.0 x 10{sup 21} dyne-cm) the corner frequency remains constant the size of events diminishes. Hutchings and Wu (1990) found that for the southern California region, events with moment less than about 1.5 x 10{sup 21} dyne-cm (about magnitude 3.4) show no source ...

Elk and Deer Study, Material Disposal Area G, Technical Area 54: Source document  

Energy Technology Data Exchange (ETDEWEB)

As nuclear research has become more prevalent, environmental contamination from the disposal of radioactive waste has become a prominent issue. At Los Alamos National Laboratory (LANL) in northern New Mexico, radioactive contamination from disposal operations has raised some very specific concerns. Material Disposal Area G (Area G) is the primary low-level radioactive waste disposal site at LANL and occupies an area adjacent to land belonging to the Native American community of the Pueblo of San Ildefonso. Analyses of soil and vegetation collected from the perimeter of Area G have shown concentrations of radionuclides greater than background concentrations established for northern New Mexico. As a result, Pueblo residents had become concerned that contaminants from Area G could enter tribal lands through various ecological pathways. The residents specifically questioned the safety of consuming meat from elk and deer that forage near Area G and then migrate onto ...

Evaluation of femoral head perfusion by dynamic MRI  

International Nuclear Information System (INIS)

The purpose of this study was to evaluate the usefulness of dynamic MRI for femoral head perfusion. Objects were 64 femoral heads of 44 normal cases (20-95 years old), 10 cases (33-90 y) of femoral neck fracture and 8 cases (61-86 y) using steroid due to articular rheumatism, nephrosis and other diseases. Siemens 1.0 T Magneton Impact with body array coil was used for dynamic MRI by the fast low-angle shot 2D method for every 17 sec interval. Gd-DTPA was injected intravenously. ROI was defined in the center of femur head and of trochanter to monitor their values for the dynamic curve. Evaluation was done on the ratio of enhancement ratio (ER) in the head/trochanter and on the curve in both heads. In normal cases, the head ER was significantly lower in >60 years old cases. There was neither significant correlation between their head/trochanter ER ratios nor significant difference ...

A presentation for Virasoro algebras  

Energy Technology Data Exchange (ETDEWEB)

The entire Virasoro, Ramond and Neveu-Schwarz algebras can each be constructed from a finite number of well-chosen generators satisfying a small number of conditions. Our most economical sets consist of just two starting generators in all cases, subject to no more than six conditions for the Virasoro case, five conditions for the Ramond case, and nine conditions for the Neveu-Schwarz case. Consequently, the Virasoro algebra simply amounts to 6 equations in two operator unknowns, and correspondingly 5 to 9 equations for the foregoing superalgebras. 2 refs.

Corrected transposition of the great arteries  

International Nuclear Information System (INIS)

The corrected transposition of the great arteries is an usual congenital cardiac malformation, which consists of transposition of great arteries and ventricular inversion, and which is caused by abnormal development of conotruncus and ventricular looping. High frequency of associated cardiac malformations makes it difficult to get accurate morphologic diagnosis. A total of 18 cases of corrected transposition of the great arteries is presented, in which cardiac catheterization and angiocardiography were done at the Department of Radiology, Seoul National University Hospital between September 1976 and June 1981. The clinical, radiographic, and operative findings with the emphasis on the angiocardiographic findings were analyzed. The results are as follows: 1. Among 18 cases, 13 cases have normal cardiac position, 2 cases have dextrocardia with situs solitus, 2 cases have dextrocardia ...

Transpositions and malpositions of the great arteries  

International Nuclear Information System (INIS)

The transposition of the great arteries afters to an abnormal connection and relation of the great arteries in which the aorta arises from the morphologic right ventricle and the pulmonary artery from the morphologic left ventricle, while the malposition of the great arteries indicates an abnormal relationship between the great arteries in which the great arteries are not transposed across the ventricular septum but they are malposed, as is seen in double outlet right ventricle, double outlet left ventricle and single ventricles. Transpositions and malpositions of the great arteries are understood as a spectrum of malformation caused by abnormal conal development and can be included in the common category of 'conotruncal malpositions'. Authors analized 32 cases of transpositions and malpositions of the great arteries in which cineangiocardiographies were done at the Department of Radiology, Seoul National University Hospital in recent 17 months, with specific ...

Quantum corrections to the Larmor radiation formula in scalar electrodynamics  

CERN Document Server

We use the semi-classical approximation in perturbative scalar quantum electrodynamics to calculate the quantum correction to the Larmor radiation formula to first order in Planck's constant in the non-relativistic approximation, choosing the initial state of the charged particle to be a momentum eigenstate. We calculate this correction in two cases: in the first case the charged particle is accelerated by a time-dependent but space-independent vector potential whereas in the second case it is accelerated by a time-independent vector potential which is a function of one spatial coordinate. We find that the corrections in these two cases are different even for a charged particle with the same classical motion. The correction in each case turns out to be non-local in time in contrast to the classical approximation.

International Nuclear Information System (INIS)

A retrospective study of Ewing's Sarcoma at The Armed Forces Malignant Diseases Treatment Centre, Command Hospital, Pune, is presented. A total of 38 cases over a period of thirteen years have been studied. Males predominate slightly, and the common age group on presentation has been in the second and third decade. Humerus, pelvis and femur are the bones commonly affected. The initial line of management has been primarily radiotherapy, which has been over the years supplemented by combination chemotherapy. All the cases achieved remission, though only 32 cases (84 per cent) had complete remission, and the remaining only partial remission. The overall survival in those offered aggressive therapy has been over 50 per cent in two years. The present policy in the management of these cases is discussed. (author). 4 tabs.

Analysis of nonisothermal injection and falloff tests in layered reservoirs  

Energy Technology Data Exchange (ETDEWEB)

The effects of reservoir layering and gravity segregation on nonisothermal injection and falloff tests are investigated. Results show that layering does not affect injection or falloff data if all the layers are permeable and accept fluids from the wellbore. In such cases, the average permeability, skin factor, and distance to the thermal front can be calculated using the techniques developed for homogeneous reservoirs. Special considerations have to be taken for cases where several layers are impermeable or are permeable but do not accept fluids of the well face. In the first case (impermeable layers), knowledge of the total thickness of the permeable layers is required for the existing techniques to be applied successfully. In the second case, the existing techniques cannot be applied, but characteristic responses from injection and falloff test are seen; therefore, this case can ...

{sup 99m}Tc-MDP scintigraphy of femoral head necrosis following femoral neck fracture  

Energy Technology Data Exchange (ETDEWEB)

Secondary ischemic necrosis of femoral head due to loss of blood supply following to femoral neck fracture is well known. The regional distribution of bone-seeking radiopharmaceuricals in the skeleton can depend on a number of factors, but bone blood flow is a major physiological determinant of regional skeletal uptake of Tc-99m polyphosphate and bone imaging may thus be used for the evaluation of vascularity of the femoral head. The authors made a comparative study of scintigraphic findings and operative findings of 28 cases of femoral neck fracture treated at Kyung Hee University Hospital from April 1980 to May 1984. The results were as follows: 1. In 16 cases of proven avascular necorsis of femoral head, scintigraphy showed absent or decreased activity in 14 cases (87.5%), while radiography showed increased density in 10 cases (62.5%). 2.

Development of cast-in-place concrete pile installation technique for application in the presence of artesian water; Hiatsu chikasui kasho ni okeru bashouchi kui sekoho no kaihatsu  

Energy Technology Data Exchange (ETDEWEB)

When a rotary excavator is operated at locations where there is artesian water, the aquiclude is fractured under pressure of the artesian water upon the penetration of the pile tip through the aquiclude. Since the equipment is provided with a gap for the reduction of friction between the casing and the excavation face, soil and sand near the pile tip burst forth out of the ground together with underground water through the casing or along the outer circumference of the casing. The newly contrived method introduced here is a double pipe process, in which a large casing (2.0m in diameter) is driven until it lands on the aquiclude, water is injected into the casing for the creation of equilibrium between the artesian head and the head in the casing, and finally a casing as large as the pile (1m in diameter) to be installed is used for the ...

Effective radiation therapy on two cases of primary Ewing's sarcoma of the rib  

International Nuclear Information System (INIS)

Two cases of primary Ewing's sarcoma of the rib are reported, in which radiation therapy was quite effective. Case 1 was an 18-year-old female who had had an operation and radiation therapy for Ewing's sarcoma of the left 7th rib. She was referred to our hospital after a recurrent tumor was found. Radiation therapy (tumor dose 46.2 Gy) and chemotherapy were given. The tumor disappeared and there has been no relapse for 1 year and 3 months after the treatment. Case 2 was a 2-year-old-infant. Radiation therapy (tumor dose 74 Gy) was given for primary Ewing's sarcoma of the left 6th rib. The tumor became small and was successfully removed at operation. There has been no relapse or distant metastasis for 8 months following the operation. We emphasize the importance of multidisciplinary treatment in case 1 and the usefulness of preoperative radiotherapy in case 2. (author).

Usefulness of MRI in diagnosis of hepatocellular carcinoma (HCC)  

Energy Technology Data Exchange (ETDEWEB)

Sixty-six cases of histologically proven hepatocellular carcinomas (HCC) were studied by MRI. Detectability was better by MRI than by CT, especially in the tumor under 2 cm in diameter. The capsule was detected in all cases of HCC over 3 cm in diameter. The capsule was able to be diagnosed only by dynamic MRI study in some cases. High intensity on the T1-weighted image and iso or low intensity on the T2-weighted image suggested that the nodule was adenomatous hyperplasi (AH) or well differentiated HCC. MRI is concluded to be an essential modality in the diagnosis of HCC. (author).

Imaging findings of abdominal peripheral primitive neuroectodermal tumor: report of four cases with pathological correlation  

British Library Electronic Table of Contents (United Kingdom)

Peripheral primitive neuroectodermal tumors (peripheral PNETs) are rare in the abdomen. We report the imaging findings of four peripheral PNETs arising in the abdomen. Three were ill-demarcated tumors and one was a well-demarcated tumor, with extensive local invasion and lymph node metastasis in two cases, respectively. The tumors are of inhomogeneous attenuation and heterogeneous enhancement after intravenous administration of contrast materials. Although their imaging manifestations cannot distinguish them from other sarcomas, recognition of these imaging features may be helpful in suggesting the possibility of peripheral PNETs in some cases.

Foraminal stenosis complicating retained broken epidural needle tip -A case report-.  

Science.gov (United States)

Lumbar epidural anesthesia is useful in a variety of chronic benign pain syndromes, including lumbar radiculopathy, low back pain syndrome, spinal stenosis, and vertebral compression fractures. Given the increased number of epidural nerve blocks being performed, some have reported unexplained complications of a transient or permanent nature and with varying degrees of severity. However, no case has been reported of a broken epidural needle tip retained in the lumbar facet joint area. This represents the first reported case presentation of foraminal stenosis developing in a patient after a retained epidural needle tip. PMID:21286465

Computed tomography in the evaluation of soft tissue tumors  

International Nuclear Information System (INIS)

In order to evaluate the role of Computed Tomography (CT) in prediction of nature, staging and follow-up of soft-tessue tumors, the authors examined by CT 124 patients with soft tissue neoplasms who later underwent surgery (116 cases) or fine needle biopsy (8 cases). Comparison between CT and surgical or anatomical results showed that CT was able to correctly predict the benignancy or malignancy of the masses in 76% of cases but it was very seldom able to allow an hystological prediction. On the contrary CT was found to be a very useful tool for pre-therapeutic staging and follow-up of the tumors, because it gave many diagnostic information which influenced therapeutic choiches and strategies.

Compound nucleus contribution to the alpha particle scattering from "2"8Si  

International Nuclear Information System (INIS)

In the case of inelastic scattering of alpha particles to the 3"+ state, the averaged angular distributions show a characteristic shape, corresponding to the excitation of such an unnatural parity state by alpha particles in the compound nucleus process. The modified Hauser-Feshbach cross-section calculations give a good description of the averaged distributions for the alpha particle scattering to the 3"+ state and the compound nucleus parameters could be extracted. The calculations of the compounds nucleus contributions to the other states in the case of 24 MeV alpha particle scattering from "2"8Si show that this contribution is not negligible and in the case of the scattering to the 4"+ state seems to be dominant.

Clustering information from direct nuclear reactions  

International Nuclear Information System (INIS)

Direct nuclear reactions are commonly understood in terms of distorted wave (DW) formalisms. In the case of a single nucleon knockout or transfer reaction the DW analysis provides a reasonable understanding of the observed data. On the other hand the predictions based on different available information inputs have been verified with the observations consistently. In the case of direct reactions involving nuclear clusters however, the DW predictions have been found to disagree with the observations in most cases. The outcome of these and other improvements in the intermediate energy nuclear phenomena involving direct reactions are highlighted. (author). 13 refs., 18 figs.

The use of peritoneal venous shunting for intractable neonatal ascites: a short case series  

British Library Electronic Table of Contents (United Kingdom)

Introduction: Intractable ascites in neonates has a varied etiology; and often, the cause is idiopathic. The management usually consists of observation, diuretics, paracentesis, albumin replacements, and self correction. However, in some cases, the above treatment remains unsuccessful. Results: We present 2 cases of intractable ascites causing metabolic abnormalities, severe protein and immunoglobulin loss, and respiratory compromise. Although the use of peritoneovenous shunts for intractable ascites has been reported previously, our cases differ in both technique and patient size. Our first patient is an ex-28-week premature, 1.4-kg infant with intractable ascites for which a peritoneal drain was initially placed.

We compare the accretion flow onto the neutron star induced by Roche lobe overflow with that by the overflow from the Be disk, in a zero eccentricity, short period binary with the same mass transfer rate, performing three-dimensional Smoothed Particle Hydrodynamics simulations. We find that a persistent accretion disk is formed around the neutron star in both cases. The circularization radius of the material transferred via Roche lobe overflow is larger than that of the material transfered from the Be disk. Thus, the growth of the accretion disk in the former case becomes significantly slower than in the latter case. In both cases, the mass accretion rate is very small and varies little with orbital phase, which is consistent with the observed X-ray behaviour of Be/X-ray binaries with circular orbits (e.g. XTE J1543-568).

Means for transferring knowledge in the relocation of manufacturing units  

DEFF Research Database (Denmark)

Based on case studies and action research, this paper investigates and discusses appropriate means for transfer knowledge when relocating manufacturing units. The cases include relocations both within the country and overseas. A framework for identifying suitable means is developed based on the situations which are extracted from the cases. Two parameters are used to classify the situation: the complexity of knowledge, and the environment for transferring the knowledge. Four different groups of means are identified from the case studies; 1) Documents or manuals and peer-to-peer training, 2) Scenarios on real systems, 3) Prototypes and games, and 4) Emulation. These means are evaluated based on the parameters in the framework and proper means are positioned in the framework. This framework can be used to support learning to develop knowledge in the new manufacturing unit.

Massive Lesions Owing to Motorcyclist Impact Against Guardrail Posts: Analysis of Two Cases and Safety Considerations*  

British Library Electronic Table of Contents (United Kingdom)

Abstract:- Two motorcycle riders lost control of their vehicle, fell, and hit a guardrail, which acted as a blade and led to a rapid, fatal outcome. In one case, the high velocity of the body at the time of the impact resulted in complete detachment of the trunk. Reconstruction of the accident dynamics enabled the guardrail post to be identified as the means of injury in both cases. The two accidents occurred over a short period of time, highlighting a dangerous phenomenon that in less severe cases is presumably associated with different degrees of survivor disability. The accidents deserve mention, because a different design of the impact surface of the guardrail post might have prevented the lethal outcome. There is an urgent need for legislators to pass regulations that modify crash bar...

Laparoscopic single stage and staged orchiopexy.  

Science.gov (United States)

The initial series of laparoscopic single stage orchiopexy for the abdominal or emergent impalpable undescended testis is reported. The first laparoscopic orchiopexy was performed at our institution in October 1991. Between October 1991 and January 1993, 14 patients (16 testes) underwent minimally invasive surgery with 6 months of followup in all cases. No evidence of testicular loss or acute atrophy has occurred, with the entire procedure being accomplished by laparo-endoscopic techniques in all cases. Treatment of 3 of the 16 testicles consisted of stage 2 of staged orchiopexy, and to our knowledge these cases represent the first stage 2 orchiopexy completed by laparoscopic techniques. In those cases stage 1 was performed by laparoscopic clipping of the vessels. The details of the procedure as we now perform it are described. PMID:7915336

Laparoscopic examination of the reproductive organs in women treated for infertility; Laparoskopowa ocena narzadow plciowych u kobiet leczonych z powodu nieplodnosci  

Energy Technology Data Exchange (ETDEWEB)

The authors discuss 84 cases of laparoscopic examination of women with primary or secondary infertility. The patients qualified for this examination had undergone at least 26 weeks of conventional treatment with no effect. In 7 cases the reproductive organ was found to be in order, with fallopian tubes fully patent. In 43 cases tubar inpatency was found (using hysterosalpingographic examination). The remaining patients suffered from other reproductive organ disorders. Therefore, the laparoscopic examination made detailed recognition of the causes of infertility possible and thus helped to establish the proper treatment. Additionally, in some cases it enabled the immediate removal of the source of infertility. (author)

Placement of dental implants in the interforaminal region of the edentulous mandible is considered a safe and routine surgical procedure. Hemorrhage in the floor of the mouth has been reported as a rare, potentially life-threatening complication related to the placement of implants in this region. In this case report the authors present an immediate and a delayed case of massive bleeding in the floor of the mouth after implant placement. This highly vascularized region is vulnerable and bleeding can be induced easily by instrumentation, causing a vascular trauma, usually by perforation of lingual periostium. In almost all cases the expanding hematoma formation starts during surgery. The effect of the vasoconstrictive agent in the local anesthesic combined with an injury of the lingual arte...

Calculation of ventilation requirements in the case of intermittent pollution: application to enclosed parking garages  

Energy Technology Data Exchange (ETDEWEB)

The ventilation requirements for decontamination are normally determined with a static calculation method. In some cases, the pollutant emission is intermittent, for example in the car park of an office building, where all the cars enter and leave the place nearly at the same time. Generally, in such a case, the volume of the garage is large, consequently the time constant of the system has a high value. So a static approach would no longer stay accurate and a dynamic evaluation is needed. With the help of some assumptions, calculations remain rather simple and results can be plotted on nomographs or computed on a programmable handheld calculator. The amount of energy saved may appear very large in some cases. A sizing optimization will be required but also remains easy to compute. The paper presents the method of calculation for a single ventilation level and the optimization of a two-level ventilation.

Biaxial Bianchi type 9 quantum cosmology  

Energy Technology Data Exchange (ETDEWEB)

We investigate the quantum cosmology of spatially homogeneous models with compact spatial sections admitting a u(2) isometry algebra. The metric ansatz in these models is that of Bianchi type IX with two scale factors set to be equal. We apply the Hartle-Hawking no-boundary path integral prescription and find the semi-classical contributions to the wave function. Exact formulae are obtainable for certain contributions and otherwise the limits of large and small anisotropy (for the pure vacuum case) and large spatial volume or small anisotropy (for the case with a positive cosmological constant) are considered. For the pure vacuum case we find no semiclassical components which would correspond to Lorentzian universes. For the case with a cosmological constant the Hartle-Hawking boundary conditions formally constrain one of the parameters in the Lorentzian solutions to be purely imaginary. Possible ...

Percutaneous intervention in the menagement of insufficient native arteriovenous hemodialysis fistulae  

Energy Technology Data Exchange (ETDEWEB)

To determine the effectiveness and patency of percutaneous intervention in insufficient native arteriovenous hemodialysis fistulae (AVFs). Between March 1997 and September 2001, 67 cases of insufficient native AVFs resulted from central vein lesion, PTA was performed in 48 cases, and thrombolytic therapy with or without PTA in 11. In eight of the cases, in which central vein stenosis had led to the insufficency, percutaneous transluminal angioplasty (PTA) was performed, and in three of the eight, a stent was inserted. Angiography findings and complications, as well as success and patency rates in the non-thrombosis and thrombosis group, were evaluated; the central vein lesion group was analysed separately. Among 84 lesions observed at angiography, three were 54 cases of stenosis, 17 of occlusion, and 13 of combined thrombosis. The lesions were located in a proximal vein (n=51), distal vein (n=14), ...

Convective heat transfer in annular flow  

International Nuclear Information System (INIS)

Several aspects of heat transfer at the annular two phase flow regime are considered. Nucleate boiling is supposed to be absent. Theoretical solutions for cases of laminar and turbulent flow in the liquid film, respectively, are considered, when steam presence does not effect the heat transfer. Heat transfer in annular flows is also considered, where steam phase consists totally or partially of the so-called incondensable gas. In this case steam phase can be a considerable resistance to heat transfer.

[Comparison of wound morphology following gunshots by machine guns and sub-machine guns].  

Science.gov (United States)

Automatic weapons such as machine guns and submachine guns are found in the German-speaking region only in special army and police units and appear accordingly rarely in homicides, suicides and accidents. In the following, the findings in two cases of death with the use of machine and submachine guns are presented. The first case was a fatal accident during shooting on a training area (current machine gun of the German army, calibre 7.62 x 51 mm), the second case was a killing during a physical conflict (submachine gun MP 40 from World War II, calibre 9 x 19 mm). In the case with the machine gun autopsy disclosed typical entry holes corresponding to the calibre, but unusually large exit wounds with tissue bridges in the wound ground, measuring 4 x 2.5 cm in diameter. By contrast, the second case (submachine gun) showed "normal" entry and exit wounds. The differences are mainly ...

Seismic tomography inversion in the case that sources and receivers are distributed out of a 2-D plane; Shingen jushinten ga nijigen heimennai ni nai baai no danseiha tomography kaiseki ni kansuru kosatsu  

Energy Technology Data Exchange (ETDEWEB)

In the case where sources and receivers are not distributed on a 2-D plane, seismic tomography inversion was studied. In tomography experiments, the existing wells are generally used. In such case, sources and receivers are frequently not distributed on a 2-D plane. The 2.5-D analysis method including 2-D structure and 3-D ray-tracing was thus developed. This method is featured by less memory necessary for ray-tracing calculation, and the same algorithm for velocity determination as 2-D analysis method. In previous methods, since analysis is generally carried out by projecting sources and receivers on a certain assumed 2-D plane, it can derive correct results in the case of constant velocity and straight ray, however, in the other case, it derives incorrect results. Application of 3-D tomography requires a large amount of memory, and falls into poor convergence because of various parameters. The 2.5-D ...

Combined peritoneography and computerized tomography for evaluating abdominal complications in patients undergoing continuous peritoneal dialysis  

International Nuclear Information System (INIS)

Continuous ambulatory peritoneal dialysis (CAPD) is a generally well-tolerated treatment. However, some patients exhibit such complications as to prevent the continuation of treatment. Peritonitis is the major problem, but the continuation of treatment may also be undermined by different complications, such as peritoneal leakage, hernia, catheter malfunctioning, and scrotal-penile edema; a careful investigation of the patient is always needed in such cases. From November 1985 to February 1990, we examined 20 patients, who had presented with different types of complications in the course of dialysis. Peritoneography demonstrated 3 cases of abdominal hernias, 2 cases of patency of the peritoneal-vaginal duct, and 2 cases of catheter obstruction. Peritoneal CT allowed the identification of leakage in 3 patients, while the combined use of the two techniques showed adhesions or pathologic peritoneal recesses ...

Clinical evaluation of serum ferritin to iron ratio in malignant diseases  

Energy Technology Data Exchange (ETDEWEB)

Serum ferritin levels were measured in 72 normal subjects and in 214 cases with various diseases by an immunoradiometric assay. In normal subjects, the serum ferritin levels were 27-230 ng/ml. Elevated serum ferritins were observed in most cases with iron excess and acute hepatitis. Markedly elevated levels were found in the majority of cases with acute leukemia, malignant lymphoma, hepatoma, and pancreatic cancer. High ferritin levels were also found in other malignant diseases. However, the range overlapped broadly with that of nonmalignant diseases. The serum ferritin correlated significantly with serum iron in normals and in those with iron deficiency anemia. In most nonmalignant cases, the serum ferritin and iron levels distributed on a regression line obtained from levels in normals and those with iron deficiency anemia. However, 92% of the malignant cases showed a serum ...

Cardiac Malpositions  

International Nuclear Information System (INIS)

Cardiac Malposition refers to any position of the heart other than a left-sided heart in a situs solitus individual. Associated cardiac malformations are so complex that even angiocardiographic and autopsy studies may not afford an accurate information. Although the terms and classifications used to describe the internal cardiac anatomy and their arterial connections in cardiac malpositions differ and tend to be confusing, common agreement exists on the need for a segmental approach to diagnosis. Authors present 18 cases of cardiac malpositions in which cardiac catheterization and angiocardiography were done at the Department of Radiology, Seoul National University Hospital between 1971 and 1979. Authors analyzed the clinical, radiographic, operative and autopsy findings with the emphasis on the angiocardiographic findings. The results are as follows: 1.

The Prognostic Significance of p53, Bcl-2, Cytokeratin 20 and Ki-67 in Primary Superficial Papillary Transitional Bladder Carcinoma  

International Nuclear Information System (INIS)

Identification of factors that determine individual patient risk for recurrence and progression in superficial papillary carcinoma of the bladder is a subject of extensive research as it would be a major outcome in patient management. It has been well recognized that traditional prognostic markers as tumor grade and stage are not accurate enough in predicting biological behavior. A large number of markers have been investigated as potential prognostic factors and relatively few can help in predicting outcome. Material and Methods: Forty-nine cases undergoing complete transurethral resection for primary superficial papillary transitional cell carcinoma were subjected to clinicopathologic evaluation as well as immunohistochemical staining for p53, bcl-2, cytokeratin 20 and Ki-67. The CAS-200 image analyzer was used to estimate the Ki-67 labeling index. Results: Recurrence was observed in 19 cases (38.8%) and progression in 7 ...

[Dysspermia due to inflammation. The evaluation of sperm cultures].  

Science.gov (United States)

The study evaluates 160 cases of positive spermioculture taken from 522 sterile individuals examined by the authors at the Couple Sterility Outpatient unit in Department A of the Institute of Gynecology and Obstetrics at Turin University during the period between January 1984 and December 1993. The germs responsible for infection were assayed in order to evaluate the strains which showed the highest incidence every year. Whereas there was no significant change in the absolute number of cases of sterility over the period, the number of cases caused by infection increased significantly during the second five-year period. It was found that the germs predominantly implicated in the genesis of male sterility formed part of the so-called mixed flora group, responsible in women for syndromes of often asymptomatic bacterial vaginosis which are not identified and consequently not treated.

The interventional treatment for biliary recurrent obstruction after palliative T tube drainage in patients with obstruction due to cholangiocarcinoma  

International Nuclear Information System (INIS)

Objective: To explore the interventional method to treat biliary recurrent jaundice after T tube drainage in patients with malignant obstructive jaundice due to cholangiocarcinoma. Methods: 7 biliary metallic stents were placed in 7 patients with recurrent jaundice after T-tube drainage in cholangiocarcinoma cases. Results: Stent placement was once successful in all 7 cases with successful rate of 100%. For all cases, TBIL, ALT, GTP and AKP values 7 days postoperatively were significantly lower than that of preoperation together with subsidence of jaundice satisfactorily for 100% after the treatment. Conclusions: Percutaneous placement of biliary metallic stents was effective economic, minimal invasive and safe for palliation of biliary recurrent jaundice after T tube drainage in cholangiocarcinoma-induced obstructive jaundice

The influence of chemically active gas on the light emission of metallic targets bombarded by positive ions  

International Nuclear Information System (INIS)

The introduction of oxygen in the vicinity of a metallic target surface, bombarded with positive argon ions of twenty kiloelectron-volts, increases the number of sputtered atoms in the excited state. This phenomenon of exaltation, very sensitive in the case of nickel and aluminium, is much less marked in the case of molybdenum. Moreover, the emission of excited particles coming from the beam's ions is not modified. A quantum-mechanical model of a kinetic emission process, which permits the interpretation of the clean metallic target's emission phenomena, seems insufficient to explain all of the results obtained in the presence of oxygen. In this last case one can therfore use a thermodynamic model in which excited metallic particles can be formed directly by chemical surface reactions of neutralization or reduction. (orig.).

Tetracycline ulcers of the oesophagus  

Energy Technology Data Exchange (ETDEWEB)

Two cases of tetracycline ulcers of the oesophagus are reported and compared with thirteen other cases from the literature. In most cases, the patients had taken their capsules with little or no fluid just before going to bed. Some hours later they developed retrosternal pain that was intensified by swallowing. Endoscopy showed sharply demarcated greyish-white areas of mucosal damage which represented layers of stratified squamous cells, separated by oedema, and a dense neutrophilic infiltration of the lamina propria and the muscularis mucosa. Roentgenology was unsuitable to detect the lesions. They healed without complications within one to six weeks. Prolonged retention of the capsules in the oesophagus is thought to cause the mucosal damage. Patients on oral tetracycline or doxycycline treatment should therefore be instructed to take their capsules with a meal or with copious water and not just before going to bed.

Structure and properties of stainless steels after plasma immersion ion implantation and plasma nitriding; Struktur und Eigenschaften nichtrostender Staehle nach einer Plasmaimmersionsionenimplantation und einer Plasmanitrierung  

Energy Technology Data Exchange (ETDEWEB)

Stainless steels can be nitrided at temperatures {<=}400 C to increase their hardness and wear resistance without a decreasing of their excellent corrosion resistance. Structure and properties of the surface layers produced by plasma nitriding and plasma immersion ion implantation in this temperature range were tested. There are negligible differences in the structure of the produced surface layers in spite of different interaction principles of the used technologies. However there are clear differences between the case of different steels. The case of ferritic chromium steels mainly consists of {epsilon}-nitride. Whereas the cases of austenitic and ferritic austenitic steels are characterized by expanded austenite. The corrosion resistance of the steels is reduced by nitriding only, if evident CrN-formation occurs. (orig.) 11 refs.

Sonography, Computed Tomography and ERCP in the diagnosis of focal exocrine pancreatic disease  

International Nuclear Information System (INIS)

In spite of the improved imaging techniques currently available, mortality for pancreatic cancer is still high, and pancreatics is often diagnosed only in its advanced stages. The authors investigated the value of different imaging techniques - i.e., US, CT, and ERCP - for an early diagnosis, when a more effective (curative?) treatment can be suggested. Fifty-six cases of pancreatic cancer and 36 cases of chronic pancreatitis were evaluated. The results indicate that ERCP, with the help of statistical methods, is superior to US and CT not only in evaluating early neoplastic or inflammatory lesions, but also for their differential diagnosis. In the letter case, ERCP can sometimes be used as a valid alternative to fine-needle aspiration biopsy.

Radiation-induced large intracranial vessel occlusive vasculopathy.  

Science.gov (United States)

Two patients who developed large intracranial vessel occlusion after standard radiation therapy for brain tumor are described. This form of vascular occlusion is usually seen in patients who have previously been treated by radiotherapy for intracranial tumor who then develop a relatively acute change in neurologic status. Histology of the lesion mimics accelerated focal arteriosclerosis. The clinical and radiographic manifestations of one case were highly atypical. The vasculopathy became evident shortly after termination of radiation therapy for a fourth ventricular ependymoma, and the angiographic picture stimulated a diffuse arteritis. The second patient was more typical, with clinical symptoms developing 12 years after radiation therapy for an oligodendroglioma. Occlusion of a proximal vessel that had been included in the radiation port was demonstrated radiographically and confirmed by pathologic examination. The clinical, angiographic, and histologic features ...

Quantifying costs of forecast errors: A case study of the warehouse environment  

British Library Electronic Table of Contents (United Kingdom)

Our study evaluates the impact of forecast errors on organizational cost by simulating a labor-intensive warehouse environment using realistic cost data from a case study. Unlike past studies that measure forecast error in terms of forecast standard deviation, our study also considers the impact of forecast bias, and the complex interaction between these variables. Two cases of organizational cost curves are considered, with differing and asymmetric structures. Results find forecast bias to have a considerably greater impact on organizational cost than forecast standard deviation. Particularly damaging is a high bias in the presence of high forecast standard deviation. Although biasing the forecast in the least costly direction is shown to yield lower costs, sensitivity analysis shows that...

Pseudospin symmetry and the relativistic harmonic oscillator  

CERN Document Server

A generalized relativistic harmonic oscillator for spin 1/2 particles is studied. The Dirac Hamiltonian contains a scalar, $S$, and a vector, $V$, quadratic potentials in the radial coordinate, as well as a tensor potential, $U$, linear in $r$. Setting either or both combinations $\\Sigma=S+V$ and $% \\Delta=V-S$ to zero, analytical solutions for bound states of the corresponding Dirac equations are found. The eigenenergies and wave functions are presented and particular cases are discussed, devoting a special attention to the non-relativistic limit and the case $\\Sigma=0$, for which pseudospin symmetry is exact. We also show that the case $U=\\Delta=0$ is the most natural generalization of the non-relativistic harmonic oscillator. The radial node structure of the Dirac spinor is studied for several combinations of harmonic oscillator potentials, and that study allows us to explain why nuclear intruder levels cannot be ...

Primary cutaneous Ewing's sarcoma/primitive neuroectodermal tumor manifesting numerous small and huge ulcerated masses: its complete remission by chemotherapy and magnetic resonance imaging findings  

International Nuclear Information System (INIS)

Extraskeletal Ewing's sarcoma (ES) and primitive neuroectodermal tumor (PNET) are widely regarded as clinically and histologically identical tumors which consist of small blue round cells. Extraskeletal ESs/PNETs usually occur in the deep soft tissues of the paraspinal region, chest wall, or lower extremities. However, superficially located cases, so-called cutaneous ESs/PNETs, are exceedingly rare, and the vast majority of the reported cases present as a single small mass. We present magnetic resonance imaging (MRI) findings and clinical course of a unique case of primary cutaneous ES/PNET presenting as numerous huge masses with severe ulceration on them. (orig.)

Orthognathic treatment case after severe root resorption in the early treatment stage  

British Library Electronic Table of Contents (United Kingdom)

This article presents an orthognathic treatment case after severe apical root resorption of maxillary anterior teeth using anterior segmental osteotomy. This case involved a 20-year-old female with the chief complaint of maxillary protruding and irregularly aligned mandibular anterior teeth. Her medical history showed no allergies or medical problems. The overbite was +3.0mm, and the overjet +3.0mm. After extraction of the four first premolars, a multi-bracket treatment was started. A severe root resorption of the maxillary anterior teeth was found 12 months after active treatment. The maxillary anterior segmental osteotomy was chosen as the compensatory treatment. The total treatment period was 2 years and 7 months. The post-retention panoramic radiograph showed no developmental root reso...

On the development of a new methodology for groundwater-driven health risk assessment  

Science.gov (United States)

A methodology and hypothetical case study are presented for incorporation of uncertainty and variability into calculations of human health risk appropriate for regional, or basin-scale, groundwater management problems. Uncertainty in well water concentration is introduced through complex contaminant migration patterns in the subsurface. Variability is considered in parameters related to individual behavior patterns and biological effects and to groundwater extraction and distribution networks. A joint uncertainty and variability (JUV) analysis is used to generate a two-dimensional distribution or risk surface that spans both transport uncertainty as well as individual variability. Cuts in this distributional surface (fractiles of variability and percentiles of uncertainty) are presented and discussed. Comparisons with alternative approaches based upon deterministic transport models are also made. In addition, important distinctions are made between the ...

Molecular dynamics simulation of effect of indenter shape on nanoscratch of Ni  

British Library Electronic Table of Contents (United Kingdom)

Thin films of Ni and Ni alloy have been widely used in microelectromechanical systems (MEMS) and magnetic storage systems. As the dimensions of components in these systems decrease to the micro-scale, even the nano-scale, the interfacial phenomena significantly differ to the counterparts on the macro-scale. A better understanding of micro-/nano-tribology will benefit the fabrication of the small components. In this manuscript parallel molecular dynamics (MD) simulations have been conducted to investigate the nanoscratch behavior of nickel. The simulations are performed for two cases with different indenter shapes. Case I has a sharp indenter, while the indenter in Case II is blunt. It has been found that the indenter shape significantly influences the nanoscratch deformation. The sharp ind...

Massive and massless representations of the super-Poincare algebra in 10 dimensions and the decomposition of the scalar superfield  

International Nuclear Information System (INIS)

Casimir operators and the Cartan subalgebra are used to construct the scalar superfields in 10-dimensions. In massless case it is shown that the scalar superfield contains two irreducible pieces, one bosonic and one fermionic. The bosonic one contains the supergravity multiplet. Supersymmetric version of the Cartan subalgebra is used to obtain the explicit expressions of the irreducible superfields. In massive case the scalar superfield contains two bosonic and one fermionic irreducible components. It is shown explicitly that the one of the bosonic pieces reduces to the above mentioned massless bosonic piece containing the supergravity multiplet in the massless limit. Supersymmetric generators corresponding to the root vectors of the Lie algebra are found and used with the Cartan subalgebra to construct the irreducible scalar superfields. Finally this method is also applied to the 4-dimensional case and as a result the ...

Lacrimal gland masses on CT and MRI: a report of four cases  

International Nuclear Information System (INIS)

In an extended case report, we discuss four cases with masses in the lacrimal fossa representing the most important entities in this region (lymphoma, pleomorphadenoma, inflammatory pseudotumor, and malignant epithelial tumor). The different indications for CT and MRI are explained. For the differential diagnosis of lacrimal gland lesions, the following imaging parameters are important: The shape of the lacrimal gland, the inner structure, the degree of contrast enhancement, and the surrounding bony structures. In the evaluation of the expansion of lacrimal gland lesions, CT in thin slices with multiplanar reconstructions is equal to MRI. However, the contrast-enhancement of lacrimal glands is better evaluated with MRI than with CT. The bony structures are better visualized on CT than on MRI. (orig.).

Graphite as negative electrode in Li-ion batteries; Le graphite comme electrode negative dans les accumulateurs Li-ion  

Energy Technology Data Exchange (ETDEWEB)

The last developments in lithium batteries design have demonstrated the advantages of graphite: competitive cost, flat output curve, high capacity thanks to the obtention of a final compound close to LiC{sub 6}, good behaviour during cycling and a high mass energy. However, these advantages are slightly tarnished by parasite secondary reactions during the evolution of the element. Two different cases are encountered: the formation of a passivation layer (loss of Li ions and formation of irreversible bounds) and the formation of a passivation layer with a reaction between graphite and the solvent (partial destruction of the graphite crystal lattice). In the first case, the theoretical graphite insertion capacity remains at 372 mAh/g while in the second case the insertion capacity is greatly reduced. Abstract only. (J.S.)

Fourier duality as a quantization principle  

Energy Technology Data Exchange (ETDEWEB)

The Weyl-Wigner prescription for quantization on Euclidean phase spaces makes essential use of Fourier duality. The extension of this property to more general phase spaces requires the use of Kac algebras, which provide the necessary background for the implementation of Fourier duality on general locally groups. Kac algebras - and the duality they incorporate are consequently examined as candidates for a general quantization framework extending the usual formalism. Using as a test case the simplest non-trivial phase space, the half-plane, it is shown how the structures present in the complete-plane case must be modified. Traces, for example, must be replaced by their noncommutative generalizations - weights - and the correspondence embodied in the Weyl-Wigner formalism is no more complete. Provided the underlying algebraic structure is suitably adapted to each case, Fourier duality is shown to be indeed a very powerful ...

Experimental assessment of energy storage via variable speed compressor  

British Library Electronic Table of Contents (United Kingdom)

In this study, usage of a variable speed refrigeration system in latent heat thermal energy storage (LHTES) system is investigated to increase energy storage efficiency. Four different compressor speed control cases are compared to obtain a constant heat transfer fluid (HTF) temperature at the inlet of the energy storage tank. These control cases are (i) control with evaporation temperature, (ii) control with ethylene glycol temperature at the outlet section of evaporator, (iii) control with suction pressure of the compressor and (iv) on/off control. By means of the experimental analysis the best control strategy is obtained as control with Case (ii), in terms of stability of inlet temperature of heat transfer fluid, variations of energy efficiency of LHTES and coefficient of performance (...

Eosinophilia after radiotherapy for non-resected cervical cancer  

International Nuclear Information System (INIS)

The behaviors of peripheral eosinophils during radiotherapy were examined in 200 cases of non-resected cervical cancer. Before irradiation, the mean absolute eosinophil count had been 170 +- 168/mm_3, and eosinophilia (more than 500/mm_3) had been observed in 11 cases (5.5%). Postirradiation eosinophilia occurred in 126 cases (63%). The mean period between institution of irradiation and the peak of the eosinophil count was 27.8 days. The mean highest eosinophil count was 691 +- 437/mm_3, and the mean bone marrow dose in this period was 906 rad. Comparisons of the eosinophil count according to the stage showed no significant differences. (Chiba, N.).

Early-stage focal nodular hyperplasia: US/CT/MR features correlated with histology  

Energy Technology Data Exchange (ETDEWEB)

Two cases of focal nodular hyperplasia (FNH), in which ultrasound (US), computed tomography (CT), and magnetic resonance imaging (MR) studies detected an atypical hemorrhagic pattern associated with an intrahepatic arterio venous malformation (AVM) around the growths, are presented. In both cases, histology demonstrated a very early regenerative stage and necrotic-hemorrhagic areas within the lesions. In these cases, the analysis of radiological findings, surgical specimens and histology seemed to confirm the pathogenetic hypothesis suggested by Wanless: in normal liver parenchyma, a ``blood steal`` phenomenon due to congenital or acquired intrahepatic AVM could cause ischemic damage, appearing as a hemorrhagic necrotic area, the extent of which depends on the degree of residual portal supply.

Computed tomography of middle ear cholesteatomas without tympanic membrane perforation  

International Nuclear Information System (INIS)

The growth of a middle ear cholesteatoma behind a normal tympanic membrane is a rate though possible event. In such cases, CT may provide useful information for diagnosis. The results are presented of a CT study carried out on 14 patients affected with unilateral conductive hearing loss and with normal tympanic membrane. CT allowed the diagnosis of meddle ear cholesteatoma to be made in all cases. All patients were treated with surgery: 8 of them underwent tympanoplasty and 6 explorative tympanotomy. While the diagnosis of cholesteatoma was confirmed in 13 patients, in 1 case tympanosclerosis was diagnosed. CT diagnosis of middle ear cholesteatoma is based on the demonstration of a low-density soft-tissue mass, in association with bone erosion or ossicular dislocation. The author emphasizes the difficulty of a CT diagnosis of cholesteatoma in the patients with middle ear soft-tissue masses in the absence of bone ...

Code case to substitute the allowable crack angle in rules on fitness-for-service codes of JSME  

International Nuclear Information System (INIS)

The new Code Case to substitute the allowable crack angle for a circumferential surface crack in 'Rules on Fitness-for-Service (FFS)' published from The Japan Society of Mechanical Engineers (JSME). Until now, the angle of a circumferential surface crack was limited below 60deg. This is the limitation with consideration to the stability of the crack if the deep crack penetrates wall of the pipe. Therefore, a long crack (such like an SCC) was obliged to repair or replace even if it was shallow enough. Weld Overlay (WOL) repair in which strength of the original piping is ignored is also inapplicable for the same reason. In order to solve this irrationality, the new Code Case applying to the crack stability assessment when the crack angle exceeds 60deg was established, and allowable crack depth according to the crack angle were defined in it.

Case report 403: Extra-mammary Paget disease of the skin with disseminated skeletal metastases  

Energy Technology Data Exchange (ETDEWEB)

The case is presented of a 64-year-old man who complained on admission of discomfort in the right shoulder at the time of excision of a large section of the axillary skin which contained extra-mammary Paget disease. Shortly thereafter, radiological studies of the humerus and scapula showed obvious malignant disease which proved to be metastatic upon biopsy of the humerus and pathological studies of the excised area of extra-mammary Paget disease in the axillary skin. The patient died twelve months after the diagnosis was established with widespread metastatic disease. The literature on the subject was reviewed and it was demonstrated that metastases to the skeleton from lesions of the skin are relatively rare. This case is exceptional because of the rapid fatal course and the extent of metastatic disease originating in extra-mammary Paget disease of the axillary skin.

Calculation of 3-D free electron laser gain: Comparison with simulation and generalization to elliptical cross section  

Energy Technology Data Exchange (ETDEWEB)

In the previous paper, we have derived a dispersion relation for the free electron laser (FEL) gain in the exponential regime taking account the diffraction and electron`s betatron oscillation. Here, we compare the growth rates obtained by solving the dispersion relation with those obtained by simulation calculation for the waterbag and the Gaussian models for the electron`s transverse phase space distribution. The agreement is found to be good except for the limiting case where the Rayleigh length is much longer than the gain length (1-D limit). We also generalize the analysis to the case where the electron beam cross section is elliptical as is usually the case in storage rings, and derive the first-order dispersion relation.

Thin-Section CT findings of lung small peripheral adenocarcinoma detected by CT physical examination  

Energy Technology Data Exchange (ETDEWEB)

Subjects were 18 cases with adenocarcinoma of 20 mm or less in diameter, which were detected and resected surgically from September, 1993 to August, 1998. On these cases, thin-Section CT (TSCT) images were compared with pathological findings. Patients were 15 men and 3 women, with mean age of 63.4-year-old. An average tumor size was 11.5 mm (5-17 mm). According to pathological classification of Noguchi, type A as in 6 cases, type B in 3, type C in 7 and type F in 2. TSCT was carried by vas voltage =150 kVp, vas current =200 mA, beam width =2 mm, WW =2000 HU, and WL =-700 HU. The ratio of CT attenuation value in cancer by TSCT correlated with the ratio of aeration rate in the pathologic specimen. The cases of 30% or less on the ratio of CT attenuation value were 100% in types A and B, and 71% in type C. These results suggested that it is necessary to devide into two type in group of type C and the ratio ...

The bones involved were the humerus, ulna, radius, femur, clavicle and ilium. Plain films, MRI and pathology specimens were obtained. A lytic lesion with indistinct margins, endosteal erosions and periosteal reaction was seen in all cases on plain radiographs. Bone marrow signal was decreased on T1-weighted images and increased on T2-weighted images throughout the bony lesion in all cases. T2-weighted images showed extensive soft-tissue abnormalities suggesting inflammatory changes in four cases. In two cases abnormalities were limited. Extensive changes correlated histologically with an early phase lesion. Localized minor changes were associated with a mid-phase lesion. Inflammatory soft-tissue changes could be associated with ...

Scintigraphical observation of femoral head in femoral neck fractures. Comparison with histological findings  

Energy Technology Data Exchange (ETDEWEB)

In 10 cases of femoral neck fracture treated with prosthetic replacement, the preoperative sup(99m)Tc-MDP scintigraphs were investigated and then compared with each histological findings of the extracted femoral head. The appearances of the scintigraphs were classified into following 3 patterns; increased activity pattern of sup(99m)Tc-MDP uptake in the overall femoral head (type I) in 4 cases, deficient activity pattern at the lateral side correspond to weight-bearing area (type II) in 2 cases and considerably deficient activity pattern in the whole femoral head (type III) in remaining 4 cases. Histological examination of the extracted femoral heads revealed the narrow part of ischemic necrosis in type I. However type II showed extensive necrosis in the portion of deficient activity by scintigraphs and in type III, the femoral heads except articular cartilage were entirely necrotic. This classification ...

MR findings of central nervous system involvement in acquired immunodeficiency syndrome patient : a report of two cases  

Energy Technology Data Exchange (ETDEWEB)

Central nervous system (CNS) manifestations in acquired immunodeficiency syndrome (AIDS) patients are an early and common feature. The spectrum of AIDS-related CNS diseases are encephalitis caused by the human immunodeficiency virus(HIV) itself, opportunistic infection, infarct and malignancy. We experienced two cases of CNS involvement in AIDS and they were serologically diagnosed as HIV encephalitis and CNS toxoplasmosis, respectively. In the case of the HIV encephalitis patient, brain MRI showed a non-enhancing lesion with high signal intensity on T2WI and low signal on T1WI and there was no mass effect on the right frontal lobe, periventricular white matter, splenium of the corpus callosum or bilateral basal ganglia. In the other case of CNS toxoplasmosis, MR showed multiple nodular and rim enhanced mass lesions in the right basal ganglia, thalamus and periventricular white matter, which were of low signal intensity on ...

Enhanced CT in the diagnosis of acute appendicitis to evaluate the severity of disease. Comparison of CT findings and histological diagnosis  

Energy Technology Data Exchange (ETDEWEB)

To assess the potential of CT in evaluating the histological severity of acute appendicitis in comparison with surgical and pathological findings. The CT images of 75 patients with surgically proven appendicitis, including 10 cases of catarrhal, 34 of phlegmonous, and 31 of gangrenous appendicitis, were retrospectively analyzed for the following five CT findings: hazy periappendiceal densities, enlarged appendix, increased enhancement of the appendiceal wall, increased enhancement of the periappendiceal intestinal wall, and deficiency of the appendiceal wall. By comparing all the CT findings and the pathological severity of appendicitis (catarrhal, phlegmonous, and gangrenous), the prevalence of the five CT findings was calculated for each pathological category. Abnormal CT findings were noted in only one case of catarrhal appendicitis. Increased enhancement of the appendiceal wall was observed in all 29 cases of ...

International Nuclear Information System (INIS)

Objective: To investigate the feasibility of low-dose single-slice helical CT in pulmonary CT scan and evaluate the clinical application. Methods: Thirteen cases were selected out of 132 cases, in which low-dose (50mAs) single-slice helical CT scan of chest was performed. This set of cases included 7 cases of multiple metastatic nodules; 3 of solitary pulmonary, nodule; and 3 of pulmonary patchy lesions. Regular dose (170mAs) CT scan was also performed on all those patients. The regular dose and low dose CT scan were compared on sensitivity of detecting the lesions; the performance in demonstrating the details of the abnormalities; and the capability of revealing the segmental bronchi as well. Results: The same number and size of the pulmonary nodules were revealed with scan modalities loaded with different doses. No significant difference in demonstrating the details of the nodules and the segmental ...
