    Analyzing William Beaumont's relationship with his experimental subject, Alexis St. Martin, this article demonstrates how the "research ethics" of antebellum America were predicated on models of employment, servitude, and labor. The association between Beaumont and St. Martin drew from and was understood in terms of the ideas and practices of contract labor, informal domestic servitude, indentures, and military service. Beaumont and St. Martin lived through an important period of transition in which personal master-servant relations existed alongside the "free" contract labor of market capitalism. Their relationship reflected and helped constitute important developments in nineteenth-century American labor history.

    1979-01-01

    The 23-km Lake St. Martin crater was produced 200 to 250 million years ago in Archean granitic to amphibolic gneiss, overlain by 400 to 500 m of Ordovician to Devonian limestone and dolomite. In the present paper, a schematic model of the field geology, petrology, and geochemistry is presented. The scenario is built in part on the calculations of Kieffer and Simonds and observations made on the Lake St. Martin structure.

ALEXIS is a 113-kg satellite that carries an ultrasoft x-ray telescope array and a high-speed VHF receiver/digitizer (BLACKBEARD), supported by a miniature spacecraft bus. It was launched by a Pegasus booster on 1993 April 25, but a solar paddle was damaged during powered flight. Initial attempts to contact ALEXIS were unsuccessful. The satellite finally responded in June, and was soon brought under control. Because the magnetometer had failed, the rescue required the development of new attitude control-techniques. The telemetry system has performed nominally. They discuss the procedures used to recover the ALEXIS mission.

  7. Cool Star Binaries with ALEXIS

    Stern, Robert A.

    1998-01-01

    We proposed to search for high-temperature, flare-produced Fe XXIII line emission from active cool star binary systems using the ALEXIS all-sky survey. Previous X-ray transient searches with ARIEL V and HEAO-1, and subsequent shorter duration monitoring with the GINGA and EXOSAT satellites demonstrated that active binaries can produce large (EM approximately equals 10(exp 55-56/cu cm) X-ray flares lasting several hours or longer. Hot plasma from these flares at temperatures of 10(exp 7)K or more should produce Fe XXIII line emission at lambda = 132.8 A, very near the peak response of ALEXIS telescopes 1A and 2A. Our primary goals were to estimate flare frequency for the largest flares in the active binary systems, and, if the data permitted, to derive a distribution of flare energy vs. frequency for the sample as a whole. After a long delay due to the initial problems with the ALEXIS attitude control, the heroic efforts on the part of the ALEXIS satellite team enabled us to carry out this survey. However, the combination of the higher than expected and variable background in the ALEXIS detectors, and the lower throughput of the ALEXIS telescopes resulted in no convincing detections of large flares from the active binary systems. In addition, vignetting-corrected effective exposure times from the ALEXIS aspect solution were not available prior to the end of this contract; therefore, we were unable to convert upper limits measured in ALEXIS counts to the equivalent L(sub EUV).

    Historic monuments are subject to degradation due to exposition to surrounding meteorological conditions and groundwater. Construction of buildings consists of the plaster and material components that have porous structure. Processes like heat transport, moisture diffusion, moisturizing and drying; freezing and thawing can be found in such structures depending on environmental conditions. Monitoring of the temperature - moisture regime gives a picture on the processes running in the structure. Long term monitoring of the tower of St. Martin Cathedral in Bratislava have been performed under window sill of the belfry in exterior in south orientation. Principle of the hot-ball method is used for monitoring of the temperature and thermal conductivity. The thermal conductivity of the porous system depends on the pore content. Moisture sensors are constructed from the parent material in a form of cylinder. Sensors are calibrated for dry and water saturated stage prior installation in the walls. Monitoring has been carried out in plaster and in the masonry in a distance about 10 cm from the wall surface, where sensors are installed. Information on temperature, moisture and thermal conductivity can be gained from measured signal. Use of two sensors allows estimation on heat and moisture transport through the wall. Monitoring has been performed in the period from April 2013 up to July 2013. Monitored data are correlated to the meteorological data. Details of various effects will be discussed.

    A hydrologic analysis was made at three canal sites and four tidal sites along the St. Lucie River Estuary in southeastern Florida from 1998 to 2001. The data included for analysis are stage, 15-minute flow, salinity, water temperature, turbidity, and suspended-solids concentration. During the period of record, the estuary experienced a drought, major storm events, and high-water discharge from Lake Okeechobee. Flow mainly occurred through the South Fork of the St. Lucie River; however, when flow increased through control structures along the C-23 and C-24 Canals, the North Fork was a larger than usual contributor of total freshwater inflow to the estuary. At one tidal site (Steele Point), the majority of flow was southward toward the St. Lucie Inlet; at a second tidal site (Indian River Bridge), the majority of flow was northward into the Indian River Lagoon. Large-volume stormwater discharge events greatly affected the St. Lucie River Estuary. Increased discharge typically was accompanied by salinity decreases that resulted in water becoming and remaining fresh throughout the estuary until the discharge events ended. Salinity in the estuary usually returned to prestorm levels within a few days after the events. Turbidity decreased and salinity began to increase almost immediately when the gates at the control structures closed. Salinity ranged from less than 1 to greater than 35 parts per thousand during the period of record (1998-2001), and typically varied by several parts per thousand during a tidal cycle. Suspended-solids concentrations were observed at one canal site (S-80) and two tidal sites (Speedy Point and Steele Point) during a discharge event in April and May 2000. Results suggest that most deposition of suspended-solids concentration occurs between S-80 and Speedy Point. The turbidity data collected also support this interpretation.

    There is increasing evidence that Mars may have once been a habitable environment. Gypsum is targeted in the search for Martian biosignatures because it can host extensive cryptoendolithic communities in extreme terrestrial environments and is widespread on Mars. In this study the viability of using different spectroscopy-based techniques to identify the presence of gypsum endolithic communities was investigated by analysing various cryptoendoliths collected from the Lake St. Martin impact crater (LSM), a Mars analogue site found in Manitoba, Canada. Concurrently, the cryptoendolithic microbial community structure present was also analysed to aid in assigning spectroscopic features to microbial community members. Two main morphologies of endolithic communities were collected from gypsum deposits at LSM: true cryptoendolithic communities and annular deposits on partially buried boulders and cobbles <1 cm below the soil surface. Endolithic communities were found to be visibly present only in gypsum with a high degree of translucency and could occur as deep as 3 cm below the exterior surface. The bacterial community was dominated by a phylum (Chloroflexi) that has not been previously observed in gypsum endoliths. The exterior surfaces of gypsum boulders and cobbles are devoid of spectroscopic features attributable to organic molecules and detectable by reflectance, Raman, or ultraviolet-induced fluorescence spectroscopies. However, exposed interior surfaces show unique endolithic signatures detectable by each spectroscopic technique. This indicates that cryptoendolithic communities can be detected via spectroscopy-based techniques, provided they are either partially or fully exposed and enough photon-target interactions occur to enable detection.

    Historic monuments are subject to degradation due to exposition to surrounding meteorological conditions and groundwater. Degradation is most often manifested by deterioration of plaster, walls structure and building elements like stones. A significant attention measures are undertaken to prevent degradation of the cultural heritage throughout the world. Our contribution is to monitor the objects for recognition of the critical state when it is necessary to make adjustments to avoid destruction. Buildings consisting from the listed elements belong to porous materials. Moisture diffusion, condensation, etc. attack structure stability of the buildings. Then the moisture diffusion and effects like drying, freezing / thawing belong to the control mechanisms of the degradation. In addition to laboratory experiments concerning the mentioned effects, we simultaneously studied processes by monitoring of the cultural monuments. During monitoring we have identified diffusion of moisture associated with cycle day / night and cycle moisture /drying caused by meteorological precipitation. Long term monitoring is performed in the tower of St. Martin Cathedral in Bratislava under the window sill of the belfry in exterior at three orientations, the north, south and the west. Monitoring is carried out in plaster and in masonry about 10 cm from the wall surface. The thermal conductivity sensors are used for monitoring that operate on the principle of the hot ball method. Then thermal conductivity of porous material is a function of pore content. The sensor has shape of a ball in diameter up to 2 mm in which a heat source as well as a thermometer is integrated into one component. A small heat output is delivered into the surrounding material. The temperature response of the sensor gives information on the thermal conductivity. For use in the preservation of cultural heritage a number of measuring devices have been developed for automatic registration of temperature and moisture in

  13. Influence of water temperature on rainbow smelt spawning and early life history dynamics in St. Martin Bay, Lake Huron

    Rainbow smelt are an important prey species for native and introduced salmonines in the Great Lakes. In Lake Huron, rainbow smelt populations are characterized by variable recruitment and year-class strength. To understand the influence of water temperature on reproduction, growth, and survival during larval-fish stages, we sampled spawning tributaries and larval-fish habitats during 2008 and 2009 in St. Martin Bay, Lake Huron. Spawning by rainbow smelt occurred primarily when stream temperatures were between 3 and 10 °C, which resulted in a 7–10-day spawning period during 2008, and a 15–20-day spawning period during 2009. Regardless of these differences in spawning temperatures and duration, peak larval-fish densities during 2008 were double those observed during 2009. Length–frequency analysis of larval-fish populations during both years revealed stream-hatched fish during May and a later emergence of larval rainbow smelt during summer, presumably originating from lake spawning. Warmer bay water temperatures led to earlier emergence of lake-spawned rainbow smelt larvae during 2009. Stream-hatched fish larvae experienced large-scale mortality during May 2008 resulting in a bay population consisting primarily of lake-spawned rainbow smelt larvae, but during 2009 both stream- and lake-hatched cohorts experienced higher survival concomitant with significantly higher mean population growth rates. Higher larval-fish growth rates during 2009 appeared to be density-dependent and facilitated by warmer water temperatures during late June and cooler water temperatures during July. Temperature-mediated differences in annual growth rates and irregular contributions from stream- and lake-hatched fish larvae are important factors affecting survival and abundance of young-of-the-year rainbow smelt in Lake Huron.

  14. Hydrogeology, Water Quality, and Distribution and Sources of Salinity in the Floridan Aquifer System, Martin and St. Lucie Counties, Florida

    Reese, Ronald S.

    2004-01-01

    The Floridan aquifer system is considered to be a valuable source for agricultural and municipal water supply in Martin and St. Lucie Counties, despite its brackish water. Increased withdrawals, however, could increase salinity and threaten the quality of withdrawn water. The Floridan aquifer system consists of limestone, dolomitic limestone, and dolomite and is divided into three hydrogeologic units: the Upper Floridan aquifer, a middle confining unit, and the Lower Floridan aquifer. An informal geologic unit at the top of the Upper Floridan aquifer, referred to as the basal Hawthorn/Suwannee unit, is bound above by a marker unit in the Hawthorn Group and at its base by the Ocala Limestone; a map of this unit shows an area where substantial eastward thickening begins near the coast. This change in thickness is used to divide the study area into inland and coastal areas. In the Upper Floridan aquifer, an area of elevated chloride concentration greater than 1,000 milligrams per liter and water temperature greater than 28 degrees Celsius exists in the inland area and trends northwest through north-central Martin County and western St. Lucie County. A structural feature coincides with this area of greater salinity and water temperature; this feature is marked by a previously mapped northwest-trending basement fault and, based on detailed mapping in this study of the structure at the top of the basal Hawthorn/Suwannee unit, an apparent southeast-trending trough. Higher hydraulic head also has been mapped in this northwest-trending area. Another area of high chloride concentration in the Upper Floridan aquifer occurs in the southern part of the coastal area (in eastern Martin County and northeastern Palm Beach County); chloride concentration in this area is more than 2,000 milligrams per liter and is as great as 8,000 milligrams per liter. A dissolved-solids concentration of less than 10,000 milligrams per liter defines the brackish-water zone in the Floridan aquifer

    This report complements a series of clinical, cytogenetical, and psychological studies previously reported on a large Sardinian pedigree segregating for premutations and full mutations associated with the Martin-Bell syndrome (MBS). Using the StB12.3 probe, we report now the molecular classification of all of the critical members of the pedigree. These molecular findings are evaluated against the variable phenotypic manifestations of the disease in the course of a six-generation segregation of an MBS premutation allegedly present in a common female progenitor of 14 MBS male patients and 9 female MBS heterozygotes seen in the last two generations. The nature and stepwise progression of MBS-premutations toward the fully manifested Martin-Bell syndrome and the possibility of reverse mutational events toward the normal allele are discussed with respect to the application of the presently available diagnostic tools in genetic counseling. 12 refs., 1 fig.

    The Array of Low Energy X-ray Imaging Sensors (ALEXIS) satellite was launched from the 4th flight of the Pegasus booster on 25 April, 1993 into an 800 km, 70 degree inclination orbit. After an initial launch difficulty, the satellite was successfully recovered and is still producing 100 MB of mission data per day. ALEXIS, still going strong in its sixth year, was originally designed to be a high risk, single string, Smaller-Faster-Cheaper satellite, with a 1-year nominal and a 3-year design limit. This paper will discuss the on-orbit detector performance including microchannel plate operation, pre- and post-flight calibration efforts, observed backgrounds and impacts of flying in a high radiation environment.

    2014-12-01

    Historical ethical dilemmas are a valuable tool in bioethics courses. However, garnering student interest in reading and discussing the assigned cases in the classroom can be challenging. In an effort to actively engage undergraduate and graduate students in an Ethical Issues in Biotechnology course, an activity was developed to encourage reflection on a classical ethical dilemma between a patient, St. Martin, and his employer/caretaker, Beaumont. Two different texts were used to analyze the ethical ramifications of this relationship: a chapter in a popular press book and a short perspective in a medical journal. Participants read the book chapter for homework and discussed it in class. This easy read highlights the fundamental ethical issues in the relationship between two men. Students were then provided with a second text focusing on the scientific accomplishments achieved through Beaumont's experimentation on St. Martin. A structured worksheet prompted participants to reflect on their feelings after reading each text and create a concept map depicting the dilemma. Student-generated concept maps and written reflections indicate participants were able to list the ethical issues, analyze the situation, and evaluate the information provided. This activity not only encouraged higher-level thinking and reflection, it also mirrored the course's structured approach of using concept mapping and reflection to dissect ethical dilemmas.

    ALEXIS is one of the most sophisticated miniature satellites developed to date, and the first satellite project led by Los Alamos National Laboratory. It carries both soft X-ray astrophysics and ionospheric physics experiments. As such, it is an example for experimenters who desire better, faster, and cheaper access to space. The satellite was launch-ready 3 1/2 years after concept. The soft X-ray experiment, ALEXIS, is a novel set of wide-angle, normal incidence telescopes which scan half the sky every satellite rotation. BLACKBEARD is a broad-band receiver and digitizer designed to study ionospheric propagation in the 25--175 MHz band. The spin-stabilized spacecraft is compact and efficient; for example, it provides 50 Watts to the payload while consuming 10 Watts itself. ALEXIS will fly on a Pegasus air-launched booster. The authors discuss the ALEXIS integration history and lessons learned therein.

A ground station located at Los Alamos exclusively controls the spacecraft. The 248 pound ALEXIS satellite was launched by a Pegasus booster into a 400 x 450 nautical mile, 70 degree inclination orbit on April 25, 1993. Images from a video system on the rocket indicated that ALEXIS had been severely damaged during launch with one of the 4 solar panels breaking away from its mounting. (It later turned out that the solar paddle was still attached to the spacecraft but only through cable bundles.) Attempts at communicating with the satellite were unsuccessful until a surprised ground crew received a short transmission on June 2. By mid July, ground station operators had regained full control of the satellite and began to initiate scientific operations with both the telescope array and the VHF experiment. In this paper we will discuss a preliminary analysis of the on-orbit performance of EUV telescopes on ALEXIS.

    2000-01-01

    The surficial aquifer system beneath citrus groves in Indian River, Martin, and St. Lucie Counties, Florida, was studied to determine the effects of citrus agriculture on ground-water quality. The surficial aquifer is the primary drinking-water source for Martin and St. Lucie Counties and furnishes about 33 percent of the drinking-water for Indian River County. Water-quality samples and water-level data were collected from December 1996 through October 1998. Nitrate concentrations in ground water exceeded 10 milligrams per liter (mg/L), the U.S. Environmental Protection Agency?s maximum contaminant level for nitrate reported as nitrogen, in 5 percent of the samples from citrus groves. These exceedances occurred in samples from wells with depths of 10 feet or less at citrus groves, and mostly in samples collected during or immediately following fertilizer applications. Samples from wells with depths of 20-25 feet contained little or no nitrate. The decreased nitrate concentrations in ground water with depth was not consistent with chloride and dissolved-solids concentrations, two other common indicators of agricultural activity. Chloride and dissolved-solids concentrations remained elevated in ground-water samples from all depths at citrus groves; median chloride and dissolved-solids concentrations in samples from citrus sites were 125 and 779 mg/L, respectively. In comparison, samples from the reference site had maximum chloride and dissolved-solids concentrations of 61 and 366 mg/L, respectively. Based on the age of ground water at 20-25 foot depths (3-50 years, measured with tritium and helium-3 concentration ratios), nitrate concentrations also should have remained elevated with depth because fertilizers have been used for at least 20-30 years at these citrus groves. Nitrate concentrations decreased with depth as a result of denitrification. This could have occurred because favorable conditions for denitrification existed in the aquifer, including high

    We report new Sr, S, and B isotopic data for evaporites (gypsum, anhydrite), carbonates, melt rocks, gneisses, and groundwaters recovered in and around the Lake St. Martin (LSM) impact structure, Interlake Region, Manitoba, Canada. The LSM meteorite impacted Devonian to Ordovician carbonates and sandstones of the eastern Williston Basin, resulting in partial melting of underlying Superior Province (~2.5 Ga) gneisses of the Canadian Shield. Overlying the LSM melt rocks are red beds and evaporites (anhydrite/gypsum/glauberite) previously inferred to have been deposited during the Jurassic. The 87Sr/86Sr (lowest values cluster at 0.70836) and δ 34SCDT (+23.7 +/- 0.9‰) of the evaporites, combined with B isotope compositions of associated groundwaters (δ 11BNBS951 = +25 to +28‰), are consistent with evaporite deposition within the impact structure near the edge of an ocean-connected salina. The establishment of a marine origin for the evaporites offers a method of age assignment using the secular variation of S and Sr isotopes in seawater. Comparison of Sr and S isotope results with the seawater curves precludes Jurassic deposition for the evaporites or correlation with Watrous and Amaranth formation evaporites, previously considered correlative with those at LSM. The lowest Sr and mean of S isotope values from the LSM evaporites are similar to seawater in the latest Devonian, consistent with conodonts recovered from carbonate breccia overlying melt rocks, and we suggest this as an alternative age of the evaporites. Data presented here preclude a Jurassic age for the evaporites and therefore for the impact event.

    The Array of Low Energy X-ray Imaging Sensors (ALEXIS) satellite is Los Alamos' first attempt at building and flying a low cost, rapid development, technology demonstration and scientific space mission. The ALEXIS satellite contains the two experiments: the ALEXIS telescope array, (which consists of six EUV/ultrasoft x-ray telescopes utilizing multilayer mirrors, each with a 33 degree field-of-view), and a VHF ionospheric experiment called Blackbeard. The spacecraft is controlled exclusively from a ground station located at Los Alamos. The 250 lb. ALEXIS satellite was launched by a Pegasus booster into a 400 nautical mile, 70 degree inclination orbit on April 25, 1993. Images from a video system on the rocket seemed to indicate that ALEXIS has been severely damaged during launch with one of the 4 solar panels breaking away from its mounting.

    1999-07-08

    The ALEXIS (Array of Low-Energy X-ray Imaging Sensors) mission, serving as the first dedicated all-sky monitor in the extreme UV, has been collecting data since its launch in 1993. ALEXIS operates in a 70{degree} inclination orbit at an altitude of 800 km. The ALEXIS science mission is to observe the cosmic UV background and to study variability of EUV sources. The ALEXIS experiment is composed of six telescopes. Although the telescopes were only designed for a one-year technology verification mission, they are still functioning with much the same effectiveness as at the beginning of the mission. The telescopes comprise: (1) layered synthetic microstructure (LSM) spherical mirrors, (2) thin foil filters, and (3) microchannel plate (MCP) detectors, all enshrouded within the telescope body. The LSM mirrors select the bandpass for each telescope, while rejecting some of the HeII 304{angstrom} geocoronal radiation. The filters, constructed either from aluminum/carbon or Lexan/titanium/boron, serve to strongly reject the geocoronal radiation, as well as longer wavelength emission from bright OB stars. Each telescope detector consists of two plates, the outermost of which is curved to accurately match the spherical focal surface of the mirror. By reviewing the ground and flight histories, this paper analyzes the flight performance of the filters, including the effects of long term exposure and the formation of pinholes.

    Because ALEXIS is a spinning satellite, it is an ideal platform with which to study the time variability of the EUV cosmos. The main thrusts of this effort are to (1) detect EUV sources at known and unknown locations, (2) provide notification of transients in near real time to enable immediate follow-up from other observatories, and (3) create a time history of observed sources for comparison with previously published catalogs to aid in determining long duration variability from EUV sources.

    The 113-kg Array of Low Energy X-ray Imaging Sensors (ALEXIS) satellite was launched from the fourth flight of Pegasus on 25 April, 1993 into a 750 x 850 km, 70 degree inclination orbit. Due to damage sustained at the time of launch, ground controllers did not make contact with the satellite until late June. By late July, full satellite operations had been restored through the implementation of new procedures for attitude control. Science operations with the two onboard experiments began at that time.

    1992-01-01

    The Array of Low Energy X-ray Imaging Sensors (ALEXIS) experiment consists of a mini-satellite containing six wide angle EUV/ultrasoft x-ray telescopes. Its purpose is to map out the sky in three narrow (approximately 5 percent) bandpasses around 66, 71, and 93 eV. The 66 and 71 eV bandpasses are centered on intense Fe emission lines which are characteristic of million degree plasmas such as the one thought to produce the soft x-ray background. The 93 eV bandpass is not near any strong emission lines and is more sensitive to continuum sources. The mission will be launched on the Pegasus Air Launched Vehicle in the second half of 1992 into a 400-nautical-mile, high inclination orbit and will be controlled entirely from a small ground station located at Los Alamos. The project is a collaborative effort between Los Alamos National Laboratory, Sandia National Laboratory, and the University of California-Berkeley Space Sciences Laboratory. The six telescopes are arranged in three pairs. As the satellite spins twice a minute they scan the entire anti-solar hemisphere. Each f/1 telescope consists of a spherical, multilayer-coated mirror with a curved, microchannel plate detector located at the prime focus. The multilayer coatings determine the bandpasses of the telescopes. The field of view of each telescope is 30 degrees with a spatial resolution of 0.5 degree, limited by spherical aberration. The data processing requirements for ALEXIS are large. Each event is one of the six telescopes is telemetered to the ground with its time of arrival and position on the detector. This information must be folded with the aspect solution for the satellite to reconstruct the direction on the sky from which the photon came. Because of the way the six telescopes scan the sky, the effective exposure calculation is also very computationally intensive. ALEXIS may generate up to 100 megabytes of raw data per day, which are converted into a gigabyte per day of processed data. While the

    The work of Alexis de Tocqueville, the 19th-century social theorist who coined the term individualism, supplied a conceptual foundation for hypothesizing that individualism and collectivism, as value systems, should be directly correlated. In previous research (D. K.-S. Chan, 1994), individualist and collectivist values were negatively correlated in a sample of men, and in a combined sample of men and women (P. J. Watson, J. Sherbak, & R. J. Morris, 1998) these values were positively correlated. In the present study, a positive relationship was in fact observed in both men and women. Linkages with other measures of self and social functioning uncovered a few small associations of individualist values with maladjustment. Collectivist values predicted adjustment. These data confirm that individualist and collectivist values are compatible, just as Tocqueville had suggested, and that gender differences do not explain the conflicting results previously reported in this literature.

  6. Initialization of a Numerical Mesoscale Model with ALEXI-derived Volumetric Soil Moisture: Case Results and Validation

    NASA Astrophysics Data System (ADS)

    2006-05-01

    Soil moisture plays a vital role in the portioning of sensible and latent heat fluxes in the surface energy budget, although high spatial-resolution observations of it are quite rare. The ALEXI model contains the two-source land-surface representation of Norman et al. (1995), which partitions surface fluxes and radiometric temperature into canopy and soil contributions based on the fraction of vegetation cover within the scene. Anderson et al. (1997) and Mecikalski (1999) detail the implementation of ALEXI as a regional-scale application over the continental United States. This model relies on remote sensing data to operate, including GOES-derived surface brightness temperature changes, AVHRR-derived land cover properties, as well as synoptic weather data to operate (Mecikalski, 1999). This version of the ALEXI algorithm has been run daily on a 10 km resolution grid from the years 2002 to present. ALEXI diagnoses a fraction of potential evapotranspiration (fPET) for both the surface layer (0-5 cm) and root-zone (5-200 cm), given a calculation of the potential ET for each pixel. In current mesoscale modeling the fraction of potential ET can be directly related to a fraction of available water, which in turn can be used to calculate volumetric soil moisture for a given soil texture. Soil moisture conditions of the surface and root-zone yield a distinctive thermal signature, where moisture deficiency will lead to surfaces warming more quickly. Current land-surface models (LDAS, NLDAS) such as those used in the North American Mesoscale Model (NAM) use antecedent precipitation as the primary component to the calculation of volumetric soil moisture. These models use four layers in their soil model (0-10, 10-40, 40-100, and 100-200 cm), while ALEXI provides derived volumetric soil moisture for only two layers within the 0-200 cm depth. This discrepancy can be solved with a blending of the two layers from ALEXI to provide a reasonable representation of the observed

    2016-10-01

    Performing spectroscopic measurements of emission lines in low temperature laboratory plasmas is challenging because the plasma is often neutral-dominated and not in thermal equilibrium. The densities and temperatures are such that coronal models do not apply; meaning that generalized collisional-radiative (GCR) methods must be employed to theoretically analyze atomic processes. However, for most noble gases, detailed, level-resolved atomic data for neutral and low-charge states does not exist in the literature. We report on a new project, where we use existing atomic physics codes to calculate level-resolved atomic data for neutral and low charge states of argon and compare with previously published, term-resolved theoretical results. In addition, we use the Atomic Structure and Data Analysis (ADAS) suite of codes to calculate a GCR model for low temperature neutral argon, which we compare to published measurements of argon optical emission cross sections. Finally, we compare synthetic spectra generated from our data with observations taken from the Auburn Linear Experiment for Instability Studies (ALEXIS) in an attempt to develop new optical plasma diagnostics for electron temperature and plasma density measurements. This project is supported by the U.S. Department of Energy. Grant Number: DE-FG02-00ER54476.

    Martin Schwarzschild, the ASP Bruce Medalist for 1965, died on 10 April 1997. A refugee from Hitler's Germany who firmly embraced his adopted country, Schwarzschild not only solved a number of fundamental problems in stellar structure and evolution but also taught the rest of the astronomical community how to do so with his 1958 text, Structure and Evolution of the Stars. At about the time of his 1979 retirement, he turned to a completely different question of how to model spheroidal galaxies self-consistently and sent another generation of students and collaborators forward toward the still somewhat distant solution. It is impossible for anyone who ever interacted with Schwarzschild to remain entirely solemn when remembering him. (SECTION: Obituary)

    2008-12-01

    Australia has been cited as a weak link in anthropogenic models of megafauna extinction, but recent work suggests instead that the evidence for rapid extinction shortly after human arrival is robust. The global model is revisited, based on the contention that late Pleistocene megafauna extinctions took place rapidly on islands, and some islands (such as Australia and the Americas) are much larger than others. Modern dating methods are increasingly able to refine chronologies, and careful scrutiny suggests that hundreds of dates should be deleted from archives. An updated summary of results from New Zealand, North America and Australia is presented, with a brief discussion on why temperate refugia offering protection from climate change ultimately did not work, strongly supporting the global extinction hypothesis pioneered by Paul Martin.

    Martin Luther achieved great success in religious reformation, though he was said to have suffered from many kinds of diseases during his lifetime. Unfortunately, however, his medical history has never been reported in Japan. Since the second half of his thirties, he was suffering from severe constipation, causing hemorrhoids and anal prolapse. At the beginning of his forties he had vertigo, tinnitis and headaches, which were the signs of chronic purlent otitis media and ended in left otorrhea and pyorrhea of the left mastoiditis. Nearly at the same time, he started to suffer from anginal pain, colic and dysuria due to urinary uric acid stones, gout and left leg ulcer, which were all caused by metabolic syndromes. The last 1/3 of his life was affected by the shadow of diseases, and his religious activities were frequently disturbed. He died from myocardial infarction at the age 63, in February 1546.

    Martin, Rod; Kuiper, Nicholas A

    2016-08-01

    Since the start of the 21st century, the investigation of various psychological aspects of humor and laughter has become an increasingly prominent topic of research. This growth can be attributed, in no small part, to the pioneering and creative work on humor and laughter conducted by Professor Rod Martin. Dr. Martin's research interests in humor and laughter began in the early 1980s and continued throughout his 32 year long career as a professor of clinical psychology at the University of Western Ontario. During this time, Dr. Martin published numerous scholarly articles, chapters, and books on psychological aspects of humor and laughter. Professor Martin has just retired in July 2016, and in the present interview he recounts a number of research highlights of his illustrious career. Dr. Martin's earliest influential work, conducted while he was still in graduate school, stemmed from an individual difference perspective that focused on the beneficial effects of sense of humor on psychological well-being. This research focus remained evident in many of Professor Martin's subsequent investigations, but became increasingly refined as he developed several measures of different components of sense of humor, including both adaptive and maladaptive humor styles. In this interview, Dr. Martin describes the conceptualization, development and use of the Humor Styles Questionnaire, along with suggestions for future research and development. In doing so, he also discusses the three main components of humor (i.e., cognitive, emotional and interpersonal), as well as the distinctions and similarities between humor and laughter. Further highlights of this interview include Professor Martin's comments on such diverse issues as the genetic versus environmental loadings for sense of humor, the multifaceted nature of the construct of humor, and the possible limitations of teaching individuals to use humor in a beneficial manner to cope with stress and enhance their social and

    SciTech Connect

    1994-08-01

    A video recording of the launch of the ALEXIS satellite on April 25, 1993 clearly showed that one of the four deployable solar paddles had mechanically separated from the satellite. A study was performed to determine whether the anomalous separation was caused by a mechanical failure and, if so, which components failed and what events led to the failure. From the study it became obvious that the failure was mechanical in nature, and was related to some design weaknesses and the testing sequence to which the solar paddle and associated hardware had been exposed prior to launch. Results of the study showed that the attachment hardware associated with this particular solar paddle was damaged during random vibration tests compromising its load carrying capability. Some relatively simple changes to the method with which structural analysis and testing were approached for the ALEXIS satellite are proposed. These changes will ensure that the chance for such failures to occur on future small satellite missions will be minimized.

    On 2 January 1995 Martin Stutzmann became Editor-in-Chief of physica status solidi, replacing Professor E. Gutsche, who had led the journal through the stormy period involving the fall of the Iron Curtain, the unification of Germany and the change in its Eastern part, where physica status solidi was based, from socialism as found in the real world (a German concept) to real world capitalism. In 1995 it was thought that the process had been completed (we should have known better!) and after the retirement of Prof. Gutsche the new owners of physica status solidi (Wiley-VCH) decided that a change in scientific management was desirable to adapt to the new socio-political facts and to insure the scientific continuity of the journal.Martin had moved in 1993 from my department at the Max-Planck-Institute to Munich where he soon displayed a tremendous amount of science man- agement ability during the build-up of the Walter Schottky Institute. The search for a successor as Edi- tor-in-Chief was not easy: the job was not very glamorous after the upheavals which had taken place in the editorial world following the political changes. Somebody in the Editorial Boards must have suggested Martin Stutzmann. I am sure that there was opposition: one usually looks for a well-established person ready to leave his direct involvement in science and take up a new endeavor of a more administrative nature. Nevertheless, the powers that be soon realized that Martin was an excellent, if somewhat unconventional candidate who had enough energy to remain a topnotch scientist and to lead the journal in the difficult times ahead: he was offered the job. In the negotiations that followed, he insisted in getting the administrative structures that would allow him to improve the battered quality of the journal and to continue his scientific productivity. Today we are happy to see that he succeeded in both endeavors. The journal has since grown in size and considerably improved its quality.Martin

    Martin Bergmann has contributed to our understanding of psychoanalysis for more than sixty years. A review of his contributions to psychoanalysis was completed in 1994, when Bergmann was 83 years old. Consideration of his remarkable productivity in the last twenty years clearly demonstrates the need to update this review. In these years, he extended his writing on the history of psychoanalysis, added to his contributions to an understanding of love, advanced ideas about psychoanalytic technique, and wrote two books on Shakespeare, as well as doing work in anthropology, sociology, literature, history, and religious studies. This paper reviews that work.

  12. Gravity gradiometry developments at Lockheed Martin

    NASA Astrophysics Data System (ADS)

    Difrancesco, D.

    2003-04-01

    Lockheed Martin has developed and fielded multiple configurations of the rotating accelerometer gravity gradiometer instrument. Applications for both static and moving-base measurements have been demonstrated for a variety of scenarios, including vehicle navigation, hydrocarbon exploration, mineral exploration, reservoir monitoring, underground void detection and treaty monitoring and compliance. The most recent systems built by Lockheed Martin extend the performance range of the early 4-accelerometer gradiometers by adding a second complement of four accelerometers. This achieves the benefit of lower instrument noise and improved frequency response (wider bandwidth) for stringent application scenarios. A summary of the gradiometer development history, functional concepts, instrument and system operation, and demonstrated performance will be presented. Development Background The U. S. Air Force Geophysics Laboratory (AFGL; now AFRL) instituted a program in 1982 to develop and field a moving base gradiometer system that could be used both on land and in the air. The result was the Gravity Gradiometer Survey System (GGSS) which first demonstrated the ability to make airborne gravity gradient measurements in 1987 (Jekeli, 1988). At the same time, the U.S. Navy began development of the Gravity Sensors System (GSS) for use on the Fleet Ballistic Submarine Trident II navigation subsystem. This military background paved the way for commercial uses of gravity gradiometry. Both the GSS and GGSS employed a first generation gravity gradiometer instrument (GGI), which was comprised of four accelerometers mounted on a rotating disk. The details of the GGI operation are further described in the work by Gerber and Hofmeyer (Gerber, 1978 and Hofmeyer, 1994). Recent Advancements in Gradiometer Instrumentation With the instrumentation experience gained through such programs as GSS and GGSS, Lockheed Martin embarked upon an ambitious effort in the early 1990's to further improve the

    The Lockheed Martin Orbital Space Plane System provides crew transfer and rescue for the International Space Station more safely and affordably than current human space transportation systems. Through planned upgrades and spiral development, it is also capable of satisfying the Nation's evolving space transportation requirements and enabling the national vision for human space flight. The OSP System, formulated through rigorous requirements definition and decomposition, consists of spacecraft and launch vehicle flight elements, ground processing facilities and existing transportation, launch complex, range, mission control, weather, navigation, communication and tracking infrastructure. The concept of operations, including procurement, mission planning, launch preparation, launch and mission operations and vehicle maintenance, repair and turnaround, is structured to maximize flexibility and mission availability and minimize program life cycle cost. The approach to human rating and crew safety utilizes simplicity, performance margin, redundancy, abort modes and escape modes to mitigate credible hazards that cannot be designed out of the system.

  14. Lockheed Martin T-Rex: Preliminary report

    SciTech Connect

    1997-07-31

    T-Rex is a robot which may be used in toxic or flammable environments. The assessment of the T-Rex conducted at the Lockheed Martin facility was limited in its scope. The scope of the assessment was directed by the type of equipment being used and the amount of accessibility to the equipment. Due to severe time constraints--the assessment was conducted in one day--human factors interface activities were limited. This should be considered a preliminary assessment. This report covers aspects of the technology that were available to the assessment team. Recommendations for future evaluation of this technology are also included. The contents are as follows: Electrical Considerations; General Electrical Consideration; Trailing Cables; Grounding; Surface High Voltage Distribution; Low and Medium Voltage Alternating Current Circuits; Potential for Harmful Human Factor Incidents and Enterprise Disablement; Exclusion Zone Emergency Maintenance; and Recommendations.

  15. Cleanliness verification process at Martin Marietta Astronautics

    1994-06-01

    The Montreal Protocol and the 1990 Clean Air Act Amendments mandate CFC-113, other chlorinated fluorocarbons (CFC's) and 1,1,1-Trichloroethane (TCA) be banned from production after December 31, 1995. In response to increasing pressures, the Air Force has formulated policy that prohibits purchase of these solvents for Air Force use after April 1, 1994. In response to the Air Force policy, Martin Marietta Astronautics is in the process of eliminating all CFC's and TCA from use at the Engineering Propulsion Laboratory (EPL), located on Air Force property PJKS. Gross and precision cleaning operations are currently performed on spacecraft components at EPL. The final step of the operation is a rinse with a solvent, typically CFC-113. This solvent is then analyzed for nonvolatile residue (NVR), particle count and total filterable solids (TFS) to determine cleanliness of the parts. The CFC-113 used in this process must be replaced in response to the above policies. Martin Marietta Astronautics, under contract to the Air Force, is currently evaluating and testing alternatives for a cleanliness verification solvent. Completion of test is scheduled for May, 1994. Evaluation of the alternative solvents follows a three step approach. This first is initial testing of solvents picked from literature searches and analysis. The second step is detailed testing of the top candidates from the initial test phase. The final step is implementation and validation of the chosen alternative(s). Testing will include contaminant removal, nonvolatile residue, material compatibility and propellant compatibility. Typical materials and contaminants will be tested with a wide range of solvents. Final results of the three steps will be presented as well as the implementation plan for solvent replacement.

  16. Three Decades Investigating Humor and Laughter: An Interview With Professor Rod Martin

    Martin, Rod; Kuiper, Nicholas A.

    2016-01-01

    Since the start of the 21st century, the investigation of various psychological aspects of humor and laughter has become an increasingly prominent topic of research. This growth can be attributed, in no small part, to the pioneering and creative work on humor and laughter conducted by Professor Rod Martin. Dr. Martin’s research interests in humor and laughter began in the early 1980s and continued throughout his 32 year long career as a professor of clinical psychology at the University of Western Ontario. During this time, Dr. Martin published numerous scholarly articles, chapters, and books on psychological aspects of humor and laughter. Professor Martin has just retired in July 2016, and in the present interview he recounts a number of research highlights of his illustrious career. Dr. Martin’s earliest influential work, conducted while he was still in graduate school, stemmed from an individual difference perspective that focused on the beneficial effects of sense of humor on psychological well-being. This research focus remained evident in many of Professor Martin’s subsequent investigations, but became increasingly refined as he developed several measures of different components of sense of humor, including both adaptive and maladaptive humor styles. In this interview, Dr. Martin describes the conceptualization, development and use of the Humor Styles Questionnaire, along with suggestions for future research and development. In doing so, he also discusses the three main components of humor (i.e., cognitive, emotional and interpersonal), as well as the distinctions and similarities between humor and laughter. Further highlights of this interview include Professor Martin’s comments on such diverse issues as the genetic versus environmental loadings for sense of humor, the multifaceted nature of the construct of humor, and the possible limitations of teaching individuals to use humor in a beneficial manner to cope with stress and enhance their social and

    1994-08-01

    We measured the energy cost of ectoparasitism in an experimental study of the house martin bug Oeciacus hirundinis and its main host, nestlings of the house martin Delichon urbica. Nests were randomly assigned to inoculation with 0 (control) 10, or 100 bugs during egg laying, and this resulted in statistically significant differences in parasite loads following fledging of nestlings. Parasite loads negatively affected house martin nestlings as estimated from their body mass at age 16 days and from mass loss estimated over 1 day late in the nestling period. Daily energy expenditure (KJ/d), average daily metabolic rate (ml CO2/g h), and mass independent daily energy expenditure (kJ/mass(0.67)d) did not differ significantly between experimental treatments. However, average daily metabolic rate increased with increasing intensities of ectoparasitism. Mass independent daily energy expenditure also increased with higher levels of parasite infestation. These results demonstrate that the bug imposes an energy cost on its host by elevating the level of metabolism.

  7. Raising awareness about soil diversity: The Education Programme of the Earth Sciences Museum Alexis Dorofeef, Minas Gerais, Brazil

    2012-04-01

    Soils are usually overlooked as part of geodiversity and geoheritage. Increasing the public awareness about soils is a key issue in our changing world. Furthering public awareness involves developing a better understanding of soils, their functions, importance for environment and society, as well as a personal and collective commitment in the stewardship and protection from degradation and loss. This presentation describes the Soil and Environmental Education and Outreach Programme of the Alexis Dorofeef Earth Sciences Museum of the Soil University Department in Viçosa, Brazil. The program has developed different activities linked to formal and non formal education and its main audience are basic education teachers, school children and the general public. The museum acts in different and diverse fronts, supported on a pedagogical background based on Paulo Freire's educational approach, the social-constructivism, which considers social inclusion, knowledge building, horizontal learning and collective action. In its early years, the museum was mainly focused on formal education and this changed with time as our action was reshaped into a broader outreach action stimulated by the new Brazilian government. The museum's indoor activities consist of accompanied thematic visits, hands on experiments, basic school teacher's courses, development of learning materials and methods and professional training. Beyond of the Museum space local interdisciplinary projects with basic education schools are run along with temporary expositions coupled with short courses and workshops with farmers and social movements. We present the results of the changes in awareness about soils among three main groups: school teachers, basic education children and general public. After 10 years of activities, the Soil Education action of the Museum is recognized and well spread among school communities in the town and its neighbourhood. Many school teachers approach the contents and methodologies

    According to the facial feedback hypothesis, people's affective responses can be influenced by their own facial expression (e.g., smiling, pouting), even when their expression did not result from their emotional experiences. For example, Strack, Martin, and Stepper (1988) instructed participants to rate the funniness of cartoons using a pen that they held in their mouth. In line with the facial feedback hypothesis, when participants held the pen with their teeth (inducing a "smile"), they rated the cartoons as funnier than when they held the pen with their lips (inducing a "pout"). This seminal study of the facial feedback hypothesis has not been replicated directly. This Registered Replication Report describes the results of 17 independent direct replications of Study 1 from Strack et al. (1988), all of which followed the same vetted protocol. A meta-analysis of these studies examined the difference in funniness ratings between the "smile" and "pout" conditions. The original Strack et al. (1988) study reported a rating difference of 0.82 units on a 10-point Likert scale. Our meta-analysis revealed a rating difference of 0.03 units with a 95% confidence interval ranging from -0.11 to 0.16.

    Bogousslavsky, Julien

    2014-01-01

    Jean-Martin Charcot (1825-1893) rightly is considered the father of both modern neurology and psychiatry in France and much beyond. While he never was interested in mental disease and what was called 'alienism' at the time, his career at La Salpêtrière Hospital over 30 years was mainly marked by the development of a huge group of students which focused on the study and management of hysteria. When Charcot took office at the beginning of 1862, hysteria was a 'no-man's land', medically speaking, since neither the alienists nor the internists had much interest in this condition. At La Salpêtrière, these chronic patients were largely left to themselves before Désiré Bourneville, one of Charcot's first students, convinced his chief to care for them. Subsequently, the studies of Charcot with Paul Richer, Joseph Babinski, Georges Gilles de la Tourette, Paul Sollier, Pierre Janet, and many others allowed the condition to be addressed in detail. During his stay with Charcot in 1885-1866, Sigmund Freud, a young neuropathologist at the time, became fascinated by hysteria, an interest which probably was the main start of his interest in psychology. Charcot emphasized the concept of mental factors in hysteria, along with that of a 'dynamic' lesion, which accounted for the lack of neuropathological findings in the patients. While his ideas on hysteria and hypnotism were criticized after his death even by former pupils, such as Babinski, recent findings from functional studies using magnetic resonance imaging show how accurate and often visionary Charcot's thinking was in this field.

    Owen Martin Phillips, a pioneer in geophysical fluid dynamics, died at home on 13 October 2010 in Chestertown, Md., at the age of 79. To his many friends and colleagues, Phillips was an inspirational and gracious person who combined a deep intellect, a lively spirit, and a generous heart that matched his passionate interest in the geophysical sciences. Phillips was born on 30 December 1930 in Parramatta, N. S. W., Australia. In 1948 he enrolled in the University of Sydney, where he earned a B.S. in applied mathematics in 1952. That same year, he joined the Cavendish Laboratory at Cambridge University as a research student, where he began to apply to the ocean concepts in turbulent flow recently developed by Andrei Kolmogorov, G. I. Taylor, and George Batchelor. While attending the 1956 celebration of Taylor's seventieth birthday, Phillips heard Fritz Ursell declare that “the process by which ocean waves are generated by the wind cannot be regarded as known.” In 1957 the Journal of Fluid Mechanics contained two remarkable papers offering contrasting theories for ocean wave generation. One paper, by the applied mathematician John Miles (J. Fluid Mech., 2(5), 417-445, 1957), proposed that energy transfer from the air to the sea occurs at a critical layer in the atmosphere boundary layer. The other paper, by Phillips, then 26 years old (J. Fluid Mech., 3(2), 185-204, 1957), proposed that turbulent pressure fluctuations in the wind resonate with propagating ocean waves, forcing them to grow. Together these became known as the Phillips-Miles process, and it was the opening salvo in Phillips's 50-year career of innovative contributions to geophysics through fluid mechanics.

    In May, 1984, Martin A. Knutson was appointed Director of Flight Operations for NASA's Ames Research Center at Moffett Field, California, and also was assigned the additional position as Site Manager of the Ames-Dryden Flight Research Facility at Edwards, California, a position he held until 1990. Knutson attended the University of Minnesota majoring in electrical engineering. He began his aviation career as an aviation cadet in the U.S. Air Force in 1950. Following service in the Korea conflict and participation in developmental test and operation missions in F-84s, he joined the CIA's Air Division flying U-2s. He retired from the Air Force in 1970, having logged over 6,500 hours of flight time. In 1971 Marty Joined NASA at the Ames Research Center as manager of the Airborne Instrumentation Research Project. In 1975 he was named Chief of the Airborne Missions and Applications Division, and served in that position until assuming the position at Dryden. In his six-year tour at Dryden he maintained the facility at 100 percent operational readiness for the most intense period of Shuttle landings ever at the site. He implemented a total modernization of research aircraft support at Dryden by replacing the aging F-104s with a modern F-18 fleet. Marty provided leadership during this period to the successful implementation of a variety of flight research/test programs such as the X-29 forward-swept wing, the planned crash of a B-720 loaded with an experimental FAA fire resistant fuel additive, the F-15 Digital Electronic Engine Control project that integrated propulsion and flight controls for greater efficiency, the Pegasus Air-Launched Rocket Vehicle, the CV-990 Shuttle Landing Gear Test Vehicle, and the F-18 High Angle-of-Attack Research Vehicle. Near the end of his Dryden assignment, the USAF decided to terminate its SR-71 reconnaissance capability and destroy the airframes and associated assets. Almost alone in his belief that these unique aircraft would be needed

  17. Femoral neuropathy due to retroperitoneal bleeding. A red herring in medicine complicates anticoagulant therapy and influences the Russian Communist Revolution (Crown Prince Alexis, Rasputin).

    PubMed

    Willbanks, O L; Willbanks, S E

    1983-02-01

    Femoral neuropathy occurs when occult retroperitoneal bleeding impinges on the appropriate nerve roots. The syndrome involves the acute onset of groin and thigh pain with characteristic flexion and external rotation of the hip. It may mimic other conditions such as acute arterial occlusion. Thorough knowledge of the anatomy of the femoral nerve explains the clinical features and leads the clinician to suspect the occurrence of this syndrome. Three cases have been reviewed that exhibited this condition as a result of retroperitoneal bleeding, a complication of systemic heparin therapy. The hemophilia that afflicted Alexis, the Crown Prince of Russia and son of Tsar Nicholas and Tsarina Alexandra, resulted in this clinical syndrome. The consequences enabled the sinister starets, Gregory Rasputin, to become intimately involved with the royal family, influencing the response of the Tsar to the political events in Russia, thereby playing an important role in setting the stage for the 1917 Russian communist revolution.

    This is an artist's conception of the NASA/Lockheed Martin Single-Stage-To-Orbit (SSTO) Reusable Launch Vehicle (RLV) releasing a satellite into orbit around the earth. NASA's Dryden Flight Research Center, Edwards, California, was to play a key role in the development and flight testing of the X-33, which is a technology demonstrator vehicle for the RLV. The RLV technology program was a cooperative agreement between NASA and industry. The goal of the RLV technology program was to enable significant reductions in the cost of access to space, and to promote the creation and delivery of new space services and other activities that were to improve U.S. economic competitiveness. NASA Headquarter's Office of Space Access and Technology oversaw the RLV program, which was being managed by the RLV Office at NASA's Marshall Space Flight Center, located in Huntsville, Alabama. Responsibilities of other NASA Centers included: Johnson Space Center, Houston, Texas, guidance navigation and control technology, manned space systems, and health technology; Ames Research Center, Mountain View, CA., thermal protection system testing; Langley Research Center, Langley, Virginia, wind tunnel testing and aerodynamic analysis; and Kennedy Space Center, Florida, RLV operations and health management. Lockheed Martin's industry partners in the X-33 program are: Astronautics, Inc., Denver, Colorado, and Huntsville, Alabama; Engineering & Science Services, Houston, Texas; Manned Space Systems, New Orleans, LA; Sanders, Nashua, NH; and Space Operations, Titusville, Florida.

    PubMed

    1987-06-01

    The population of St Lucia was 123,000 in 1986, with an annual growth rate of 2%. The infant mortality rate stands at 22.2/1000 live births, and life expectancy is 70.3 years for males and 74.9 years for females. The literacy rate is 78%. St Lucia's labor force is allocated as follows: agriculture, 36.6%; industry and commerce, 20.1%; and services, 18.1%. The gross national product (GNP) was US$146 million in 1985, with an annual growth rate of 3% and a per capita GNP of $1071. St Lucia is a parliamentary democracy modeled on the British Westminster system. The island is divided into 16 parishes and 1 urban area (the capital, Castries). St Lucia is currently a politically stable country, although the high level of youth unemployment is a cause for concern. Ongoing stability may depend on the government's ability to provide services such as jobs and housing. The economy has evolved from a monocrop sugar plantation type to a diversified economy based on agriculture, industry, and tourism. Agriculture, dominated by the banana industry, is characterized by the participation of a large number of small and medium-sized enterprises. Industry is being encouraged through the provision of incentives such as tax rebates. The government is attempting to maintain a sound investment climate through a tripartite dialogue with the private sector and trade unions. Overall economic policy is predicated on the attraction of sound investments, by both local and foreign entities, to accelerate the rate of economic growth, solve the unemployment problem, and generate a solid balance-of-payments position.

    1989-01-01

    An epidemiological study on ciguatera fish poisoning in the French West Indies (St-Barthelemy, St-Martin and Anguilla) was conducted during the years 1985-1986. The investigation on intoxications shows a non seasonal significant prevalence. Though it was difficult to list the cases, the morbidity seems to vary between 7 and 30 per thousand. A study of fish toxicity was realised; 46 different species were tested (individually or by pools) by the mosquito bio-test. Observations of intoxications give the following results: High risk species: Caranx bartholomaei, C. lugubris, Seriola dumerili, Lutjanus apodus, L. jocu, Pristipomoides macrophtalmus, Gymnothorax funebris, G. moringa, Scomberomorus cavalla, S. regalis, Mycteroperca venenosa, M. tigris, Epinephelus morio, Sphyraena barracuda. Intermediate species: Caranx latus, C. ruber, Lachnolaimus maximus, Lutjanus analis, L. buccanella, L. griseus, Malacanthus plumieri, Scomberomorus maculatus. Low risk species: Balistes vetula, Alectis ciliaris, Haemulon album, Bodianus rufus, Halichoeres radiatus, Priacanthus arenatus, Alphestes afer. Many species are involved in the toxic food chain. New ones have been identified, but it is difficult to determine the toxic level range. A cartography is presented but no place is free of risk. A research of Gambierdiscus toxicus, the causal agent, on algal surface from dead corals was conducted around St-Barthelemy and St-Martin. The dinoflagellate is found in low or medium populations all around the islands with no difference between North and South. There is a maximal activity during the spring. A model of the epidemiology of the ciguatera in the area is proposed.

  6. Nietzsche, autobiography, history: mourning and Martin and John.

    PubMed

    Champagne, J

    1998-01-01

    How might gay and lesbian literature be read not as a mimetic representation of homosexuality, but as an activity linked to problems of subjectivity and historiography? Reading Dale Peck's novel Martin and John alongside passages from Friedrich Nietzsche's "On the Uses and Disadvantages of History for Life" and Sigmund Freud's "Mourning and Melancholia," this essay argues for an understanding of Peck's text as an attempt to link two apparently different processes of import to contemporary gay male subjects in particular: the writing of what Nietzsche terms "critical history," and the mourning of those lost to HIV disease. It concludes by linking Martin and John to feminist critiques of identity and traditional historiography, as well as noting the connection between these two critiques.

    Martin Luther has been severely criticized by some scholars for a remark he made about Copernicus and his heliocentric theory. When this offhand remark, made at the dinner table four years before the publication of On the Revolutions of the Heavenly Spheres, is considered in its historical context, it is shown to be in keeping with the generally accepted scholarly opinion of the time. Luther's view of science in general and astronomy in particular is examined.

    Community involvement is not just one facet of the new Martin Luther King, Jr., General Hospital's existence. It is the mainstream from which all other activities flow. In addition to meeting the conventional needs of a conventional hospital staff with the core collection of texts and journals, this library goes one step further. It acts as a resource for its community health workers, dietitians, and nurses in their various outreach programs. It serves as a stimulus for the high school or community college student who may be curious about a health career. It also finds time to provide reading material for its patients.

  17. Measurements of Martin-Puplett Interferometer Limitations using Blackbody Source

    2013-06-01

    Frequency domain measurements with Martin-Puplett interferometer is one of a few techniques capable of bunch length measurements at the level of ~ 100 fs. As the bunch length becomes shorter, it is important to know and be able to measure the limitations of the instrument in terms of shortest measurable bunch length. In this paper we describe an experiment using a blackbody source with the modified Martin-Puplett interferometer that is routine- ly used for bunch length measurements at the JLab FEL, as a way to estimate the shortest, measurable bunch length. The limitation comes from high frequency cut-off of the wire-grid polarizer currently used and is estimated to be 50 fs RMS. The measurements are made with the same Golay cell detector that is used for beam measure- ments. We demonstrate that, even though the blackbody source is many orders of magnitude less bright than the coherent transition or synchrotron radiation, it can be used for the measurements and gives a very good signal to noise ratio in combination with lock-in detection. We also compare the measurements made in air and in vacuum to characterize the very strong effect of the atmospheric absorption.

    1996-01-01

    This is an artist's conception of the NASA/Lockheed Martin Single-Stage-To-Orbit (SSTO) Reusable Launch Vehicle (RLV) in orbit high above the Earth. NASA's Dryden Flight Research Center, Edwards, California, expected to play a key role in the development and flight testing of the X-33, which was a technology demonstrator vehicle for a possible RLV. The RLV technology program was a cooperative agreement between NASA and industry. The goal of the RLV technology program was to enable significant reductions in the cost of access to space, and to promote the creation and delivery of new space services and other activities that would improve U.S. economic competitiveness. The X-33 was a wedged-shaped subscale technology demonstrator prototype of a potential future Reusable Launch Vehicle (RLV) that Lockheed Martin had dubbed VentureStar. The company hopes to develop VentureStar early this century. Through demonstration flight and ground research, NASA's X-33 program was to provide the information needed for industry representatives such as Lockheed Martin to decide whether to proceed with the development of a full-scale, commercial RLV program. A full-scale, single-stage-to-orbit RLV was to dramatically increase reliability and lower costs of putting a pound of payload into space, from the current figure of $10,000 to $1,000. Reducing the cost associated with transporting payloads in Low Earth Orbit (LEO) by using a commercial RLV was to create new opportunities for space access and significantly improve U.S. economic competitiveness in the world-wide launch marketplace. NASA expected to be a customer, not the operator, of the commercial RLV. The X-33 design was based on a lifting body shape with two revolutionary 'linear aerospike' rocket engines and a rugged metallic thermal protection system. The vehicle also had lightweight components and fuel tanks built to conform to the vehicle's outer shape. Time between X-33 flights was normally to have been seven days, but the

    This paper describes the higher cooling capability of the Lockheed Martin coax Micro cryocooler thermal mechanical unit. The design of the previously qualified TRL6 Micro (Nast et al., 2014) [1] was modified to accommodate over twice the input power, greatly increasing the cooling capability. These Micro units are in a split configuration with the cold head separated from the compressor. This unit was optimized for cooling at 105 K and provides cooling over a wide range of temperatures. With a weight below 450 g, this small unit is ideal for compact instruments. Load lines were obtained over a range of powers, cold tip temperatures and rejection temperatures. This testing raised the Technology Readiness Level to six.

    2008-01-01

    The evidence which has accumulated on the course of agoraphobia challenges the DSM view that phobic avoidance is secondary to panic attacks. In particular, a longitudinal study by Wittchen et al. indicates that agoraphobia, as a diagnostic category, is frequently independent of panic disorder and panic attacks, is unlikely to remit spontaneously and entails compromised quality of life. A staging system of agoraphobia is presented. Panic may ensue in the longitudinal development of agoraphobia, as well as of other anxiety disorders, and be conceptualized as a potential outcome in the course of anxiety, phobias and hypochondriasis as more than a specific disease entity. These recent research findings confirm the clinical observations and phenomenological research of Sir Martin Roth (1917-2006) and call for a reassessment of the concept of neurosis.

    Martin F. McCarthy, S.J., astronomer at the Vatican Observatory from 1958 until his retirement in 1999, died peacefully on 5 February at the age of 86 years at the Jesuit Campion Health Center in Weston, Massachusetts where he had resided since his retirement. McCarthy received his doctorate in astronomy from Georgetown University, Washington, DC in 1951. The study of carbon stars, stars whose atmospheres contain more carbon than oxygen, was a major interest for McCarthy. Carbon stars were originally discovered and studied in the 1860s by Fr. Secchi, the eminent Jesuit astronomer. Interestingly, Fr. Secchi spent 1848-50 at Georgetown University in Washington, where Martin McCarthy would receive his PhD degree 101 years later. Upon completion of his seminary studies in theology, he carried out post-doctoral research at Warner and Swasey Observatory, Lick Observatory, the Dominion Astrophysical Observatory and Yerkes Observatory until he began his career at the Vatican Observatory where he served as a key figure in the Observatory's transition to the world of modern research. He also brought the Observatory onto the international stage through his collaborations in research at, among other institutes, Palomar Observatory, Lowell Observatory, Las Campanas Observatories, the Cerro Tololo Interamerican Observatory and the Carnegie Institute of Washington. He served on the Executive Council of the Italian Astronomical Society (1969-1971), was chair of the National Committee of the Vatican to the International Astronomical Union (IAU) from 1979 until his retirement and was President of IAU Commission 25 Stellar Photometry and Polarimetry (1976-1979). During his career he published more than 120 research papers. He was a natural teacher, who enjoyed explaining and talking science to students and visitors. Among his many contributions to the growth of the Vatican Observatory, he was responsible in 1986 for the beginning of the series of the Vatican Observatory Summer

  14. Copernicus and Martin Luther: An Encounter Between Science and Religion

    NASA Astrophysics Data System (ADS)

    Kobe, D. H.

    1998-03-01

    Martin Luther has been severely criticized for a remark he made about Copernicus and his heliocentric theory. When this offhand remark, made at the dinner table four years before the publication of On the Revolutions of the Heavenly Spheres, is considered in its historical context, it is shown to be in keeping with the generally accepted scholarly opinion of the time. Luther's view of science in general and astronomy in particular is much more sophisticated than indicated by this single impromptu remark. In the thought of Luther there are two sources of knowledge - experience and revelation. By experience he meant all the human disciplines (or ``science"), and by revelation he meant Biblical theology. Each discipline should have its own technical language and methods. Science and Biblical theology should not conflict, since when speaking of the same phenomena they use a different language. Luther used the clear and literal interpretation of the text of the Bible, except when there were compelling reasons for doing otherwise. Rather than use the Bible as a source of scientific facts and theories as is done by a literalist, he interpreted it as being the witness to Christ. Quotations from Luther are used to illustrate his approach.

  15. Pleistocene Deposits in Pierre Saint-Martin Cave, French Pyrenees

    NASA Astrophysics Data System (ADS)

    1998-01-01

    Pleistocene deposits in alpine Pierre Saint-Martin cave are preserved in an abandoned river gallery. The deposits, 300 m long and 25 m high, are composed of a lower unit of fallen blocks overlain by debris flows, a main unit of laminated clay, and a series of river terraces inset into these units. The lower and main units are each overlain by speleothems. The lower unit represents a cold period, probably isotope stage 10. Corroded speleothems above it have given U/Th ages greater than 300,000-330,000 yr B.P. The main unit, with carbonate-rich varves devoid of pollen, represents a glaciation that occurred before 225,000 yr B.P. and probably correlates with stage 8, even though such a glaciation has not been previously recognized in the Pyrenees. The river terraces, covered by many noncorroded speleothems, probably formed during stage 7 (U/Th ages between 194,000 and 211,000-225,000 yr B.P.). Subsequent sinking of an underground river protected the deposits from erosion.

  16. Compliance with the Aerospace MACT Standard at Lockheed Martin

    1997-12-31

    Actions taken and planned at four Lockheed Martin Corporation (LMC) facilities to comply with the Aerospace MACT Standard are reviewed. Many LMC sites have taken proactive steps to reduce emissions and implement low VOC coating technology. Significant administrative, facility, and material challenges remain to achieve compliance with the upcoming NESHAP and Control Technology Guideline (CTG) standards. The facilities discussed herein set up programs to develop and implement compliance strategies. These facilities manufacture military aircraft, missiles, satellites, rockets, and electronic guidance and communications systems. Some of the facilities are gearing up for new production lines subject to new source MACT standards. At this time the facilities are reviewing compliance status of all primers, topcoats, maskants and solvents subject to the standard. Facility personnel are searching for the most efficient methods of satisfying the recordkeeping, reporting and monitoring, sections of the standards while simultaneously preparing or reviewing their Title V permit applications. Facility decisions on paint booths are the next highest priority. Existing dry filter paint booths will be subject to the filtration standard for existing paint booths which requires the use of two-stage filters. Planned paint booths for the F-22 program, and other new booths must comply with the standard for new and rebuilt booths which requires three stage or HEPA filters. Facilities looking to replace existing water wash paint booths, and those required to retrofit the air handling equipment to accommodate the two-stage filters, are reviewing issues surrounding the rebuilt source definition.

  17. Lockheed Martin approach to a Reusable Launch Vehicle (RLV)

    NASA Astrophysics Data System (ADS)

    Elvin, John D.

    1996-03-01

    This paper discusses Lockheed Martin's perspective on the development of a cost effective Reusable Launch Vehicle (RLV). Critical to a successful Single Stage To Orbit (SSTO) program are; an economic development plan sensitive to fiscal constraints; a vehicle concept satisfying present and future US launch needs; and an operations concept commensurate with a market driven program. Participation in the economic plan by government, industry, and the commercial sector is a key element of integrating our development plan and funding profile. The RLV baseline concept design, development evolution and several critical trade studies illustrate the superior performance achieved by our innovative approach to the problem of SSTO. Findings from initial aerodynamic and aerothermodynamic wind tunnel tests and trajectory analyses on this concept confirm the superior characteristics of the lifting body shape combined with the Linear Aerospike rocket engine. This Aero Ballistic Rocket (ABR) concept captures the essence of The Skunk Works approach to SSTO RLV technology integration and system engineering. These programmatic and concept development topics chronicle the key elements to implementing an innovative market driven next generation RLV.

  18. Martin Lister (1639-1712) and fools' gold.

    PubMed

    Roos, Anna Marie

    2004-03-01

    Seventeenth-century physician Martin Lister is best known for his work in natural history and participation in the early Royal Society. However, little attention has been focused upon Lister's work in chemistry, the most salient examples being his analysis of pyrites or "fools' gold" near mineral springs in the De Fonbibus medicatis Angliae Exercitatio of 1684 (Exercises on the healing springs of England), his contributions to the Philosophical Transactions in the 1670s and 1680s, and his unpublished manuscript " A Method for the History of Iron, Imperfect." He defined pyrites more specifically as " ironstone marcasites" which were "nothing else but a body of iron disguised under a vitriolic varnish"; "vitriol" referred to iron (II) sulfate which occurred as a weathering product of pyrites. This paper demonstrates that an understanding of Lister's work on pyrites and vitriol is best attained by placing him in the intellectual context of the seventeenth-century chemical debate about minerallogenesis. Lister believed that the volatile exhalations of pyrites and its vitriol in the air were important in the transformation of matter, and he subscribed to the sixteenth-and seventeenth-century theory of witterung (weathering) or ore exhalations as an explanation for the formation of minerals. Despite his allegiance to the theories of witterung, I will illustrate that Lister made use of his interests in natural history to go one step beyond them, postulating that the sulfurous exhalations from pyrites were responsible for the heating of hot springs, as well as meteorological and geological effects.

    1996-05-01

    The Information Management Technology Architecture (TA) is being driven by the business objectives of reducing costs and improving effectiveness. The strategy is to reduce the cost of computing through standardization. The Lockheed Martin Idaho Technologies Company (LMITCO) TA is a set of standards and products for use at the Idaho National Engineering Laboratory (INEL). The TA will provide direction for information management resource acquisitions, development of information systems, formulation of plans, and resolution of issues involving LMITCO computing resources. Exceptions to the preferred products may be granted by the Information Management Executive Council (IMEC). Certain implementation and deployment strategies are inherent in the design and structure of LMITCO TA. These include: migration from centralized toward distributed computing; deployment of the networks, servers, and other information technology infrastructure components necessary for a more integrated information technology support environment; increased emphasis on standards to make it easier to link systems and to share information; and improved use of the company`s investment in desktop computing resources. The intent is for the LMITCO TA to be a living document constantly being reviewed to take advantage of industry directions to reduce costs while balancing technological diversity with business flexibility.

    Background Development and standardization of computerized color vision testing as a replacement for Martin Lantern test. Non-randomized comparative trial. Methods All candidates of SSB, Allahabad, reporting for SMB underwent color vision testing at the eye dept by computerized eye test and currently available tests. Results All candidates were subjected to Ishihara chart testing and those found to be CP III were subjected to the confirmatory test on Martin Lantern and the Software. Candidates requiring CP I standards for eligibility were tested on the same on Martin Lantern and on the new software method. On comparison between the Standard Martin Lantern and the Software, the results were consistent and comparable with 82 patients testing CP I on the Martin Lantern and 81 on the software. Of the CP III patients, 253 tested positive on the Standard lantern test as compared to 251 on the software and of the CP IV group, 147 tested positive on the Standard lantern and 149 by the software method. Conclusion It was found that the software replicated the existing Martin Lantern accurately and consistently. The Martin Lantern Software can be used as a replacement for existing old Lanterns which are not in production since the early 20th century. PMID:24532927

  5. The January 2006 Volcanic-Tectonic Earthquake Swarm at Mount Martin, Alaska

    Dixon, James P.; Power, John A.

    2009-01-01

    On January 8, 2006, a swarm of volcanic-tectonic earthquakes began beneath Mount Martin at the southern end of the Katmai volcanic cluster. This was the first recorded swarm at Mount Martin since continuous seismic monitoring began in 1996. The number of located earthquakes increased during the next four days, reaching a peak on January 11. For the next two days, the seismic activity decreased, and on January 14, the number of events increased to twice the previous day's total. Following this increase in activity, seismicity declined, returning to background levels by the end of the month. The Alaska Volcano Observatory located 860 earthquakes near Mount Martin during January 2006. No additional signs of volcanic unrest were noted in association with this earthquake swarm. The earthquakes in the Mount Martin swarm, relocated using the double difference technique, formed an elongated cluster dipping to the southwest. Focal mechanisms beneath Mount Martin show a mix of normal, thrust, and strike-slip solutions, with normal focal mechanisms dominating. For earthquakes more than 1 km from Mount Martin, all focal mechanisms showed normal faulting. The calculated b-value for the Mount Martin swarm is 0.98 and showed no significant change before, during, or after the swarm. The triggering mechanism for the Mount Martin swarm is unknown. The time-history of earthquake occurrence is indicative of a volcanic cause; however, there were no low-frequency events or observations, such as increased steaming associated with the swarm. During the swarm, there was no change in the b-value, and the distribution and type of focal mechanisms were similar to those in the period before the anomalous activity. The short duration of the swarm, the similarity in observed focal mechanisms, and the lack of additional signs of unrest suggest this swarm did not result from a large influx of magma within the shallow crust beneath Mount Martin.

  6. All in the family: a belated response to Knudson-Martin's feminist revision of Bowen theory.

    PubMed

    Horne, K Blake; Hicks, Mary W

    2002-01-01

    The first formal attempt at revising Bowen theory within the marriage and family therapy literature is represented in the work of Knudson-Martin (1994). Claiming that several of the theory's concepts are defined at odds with female development, Knudson-Martin (1994) reconceptualizes and expands Bowen theory to rectify these perceived shortcomings. In turn, we address several fundamental concerns with Knudson-Martin's critique and revision of Bowen theory. An alternative representation of Bowen Theory, as well as its relationship to feminist thought, is put forth. Suggestions for the field's future relationship to Bowen theory are also discussed.

  7. Roegneria alashanica Keng: a species with the StStSt(Y)St(Y) genome constitution.

    PubMed

    Wang, Richard R-C; Jensen, Kevin B

    2017-03-17

    The genome constitution of tetraploid Roegneria alashanica Keng has been in question for a long time. Most scientific studies have suggested that R. alashanica had two versions of the St genome, St1St2, similar to that of Pseudoroegneria elytrigioides (C. Yen & J.L. Yang) B.R. Lu. A study, however, concluded that R. alashanica had the StY genome formula typical for tetraploid species of Roegneria. For the present study, R. alashanica, Elymus longearistatus (Bioss.) Tzvelev (StY genomes), Pseudoroegneria strigosa (M. Bieb.) Á. Löve (St), Pseudoroegneria libanoctica (Hackel) D.R. Dewey (St), and Pseudoroegneria spicata (Pursh) Á. Löve (St) were screened for the Y-genome specific marker B14(F+R)269. All E. longearistatus plants expressed intense bands specific to the Y genome. Only 6 of 10 R. alashanica plants exhibited relatively faint bands for the STS marker. Previously, the genome in species of Pseudoroegneria exhibiting such faint Y-genome specific marker was designated as St(Y). Based on these results, R. alashanica lacks the Y genome in E. longearistatus but likely possess two remotely related St genomes, St and St(Y). According to its genome constitution, R. alashanica should be classified in the genus Pseudoroenera and given the new name Pseudoroegneria alashanica (Keng) R.R.-C. Wang and K.B. Jensen.

  8. Lockheed Martin Hanford Corporation systems engineering project management

    SciTech Connect

    Baynes, P.A.

    1998-04-01

    Lockheed Martin Hanford Corporation is developing and implementing an integrated technical baseline for cleaning up environmental contamination at the Hanford Site in Washington State. The Hanford Site is located in Washington State and has been referred to as one of the largest Environmental Cleanup challenges in the US. It became contaminated with radioactive and dangerous wastes during the 40+ years it was being used to produce weapons grade plutonium in support of the US nuclear weapons program (See Figure 1). The US Department of Energy (US DOE) is responsible for cleanup of the Hanford Site with the Environmental Protection Agency (EPA) and the Washington State Department of Ecology (Ecology) both providing regulatory oversight. The US DOE, EPA and Ecology entered into an agreement in 1989 (Hanford Federal Facility Agreement and Consent Order, commonly referred to as the Tri-Party Agreement) that provides the framework for cleanup of the Hanford Site. However, since the inception of the Tri-Party Agreement, there have been numerous changes due to technical issues, funding issues, and priority changes within the cleanup mission. As a result, progress on the definition and execution of the cleanup work has been slower than anticipated and has resulted in some false starts, missed milestones, and milestones that have been completed that did not further the Site cleanup. The absence of a clearly defined mission resulted in a high percentage of projects that were canceled during construction or abandoned after completion and approximately $900 million spent on projects that did not bring cleanup or disposal any closer.

  9. A new banding technique for nesting adult purple martins

    Mery (1966) showed an almost equal sex ratio, males returned more frequently than females, over 50% of returns paired with other returns, an adult return rate of 20%, and no pair bonds maintained for more than one season. Her study lasted 13 years. Our study has shown that the return rate of locals to parent colonies is 4.1%, sex ratios are nearly equal (combination of banding and observation), return rate of locals to nearby colonies is 0.9,one pair maintained the pair bond for two years, SY females lay fewer eggs than ASY's, SY adults occasionally do not feed frequently enough to maintain the normal growth pattern of the young, SY adults often build poorly constructed nests with little or no mud, overall nest success is lower in SY adults, adults do indeed return to the same colony (19.6%) box and/or compartment, sexes are balanced in a stable colony, males or females are sometimes in excess in a new colony, SY adults are predominate in a new colony, the limiting factor in colony size is most likely the number of boxes and/or compartments available for nesting and,finally, adults and young do indeed use the boxes for roosting after nesting and fledging is complete (even boxes not their own). All of our results are tentative and subject to change after f rther study. Much additional study will be required before we can come up with conclusive answers to many of these questions about the Purple Martin.

    Chalfie, Martin

    2010-02-10

    American Biologist Martin Chalfie shared the 2008 Nobel Prize in Chemistry with Roger Tsien and Osamu Shimomura for their discovery and development of the Green Fluorescent Protein (GFP). Martin Chalfie was born in Chicago in 1947 and grew up in Skokie Illinois. Although he had an interest in science from a young age--learning the names of the planets and reading books about dinosaurs--his journey to a career in biological science was circuitous. In high school, Chalfie enjoyed his AP Chemistry course, but his other science courses did not make much of an impression on him, and he began his undergraduate studies at Harvard uncertain of what he wanted to study. Eventually he did choose to major in Biochemistry, and during the summer between his sophomore and junior years, he joined Klaus Weber's lab and began his first real research project, studying the active site of the enzyme aspartate transcarbamylase. Unfortunately, none of the experiments he performed in Weber's lab worked, and Chalfie came to the conclusion that research was not for him. Following graduation in 1969, he was hired as a teacher Hamden Hall Country Day School in Connecticut where he taught high school chemistry, algebra, and social sciences for 2 years. After his first year of teaching, he decided to give research another try. He took a summer job in Jose Zadunaisky's lab at Yale, studying chloride transport in the frog retina. Chalfie enjoyed this experience a great deal, and having gained confidence in his own scientific abilities, he applied to graduate school at Harvard, where he joined the Physiology department in 1972 and studied norepinephrine synthesis and secretion under Bob Pearlman. His interest in working on C. elegans led him to post doc with Sydney Brenner, at the Medical Research Council Laboratory of Molecular Biology in Cambridge, England. In 1982 he was offered position at Columbia University. When Chalfie first heard about GFP at a research seminar given by Paul Brehm in 1989

    2014-01-01

    The presence of one of the largest colonies of House Martins in Europe on the small island of Stora Karlsö, Sweden, led us to investigate the source of their food by analysis of stable isotopes of carbon and nitrogen. Carbon isotopic values of House Martin nestlings were the same as those of Common Guillemot Uria aalge nestlings fed on marine fish, but differed from local Collared Flycatcher Ficedula albicollis nestlings fed on woodland insects. We infer that these House Martins fed their chicks almost exclusively on insects that had used nutrients derived from seabirds, indicating a dependence on the presence of a large seabird colony. We suggest by extension that some populations of island passerines of high conservation importance may also be dependent on nutrient subsidies from seabird colonies. PMID:25866414

  11. Phenomenological study of unintegrated parton distribution functions in the frameworks of the Kimber-Martin-Ryskin and Martin-Ryskin-Watt approaches

    2014-02-01

    The aim of the present work is to study the phenomenological behavior of unitegrated parton distribution functions (UPDF) by using the Kimber-Martin-Ryskin (KMR) and Martin-Ryskin-Watt (MRW) formalisms. In the first method, the leading order (LO) UPDF of the KMR prescription is extracted, by taking into account the PDF of Martin et al., i.e., MSTW2008-LO and MRST99-NLO and. While in the second scheme, the next-to-leading order (NLO) UPDF of the (MRW) procedure is generated through the set of MSTW2008-NLO PDFas the inputs. The different aspects of the UPDF in the two approaches, as well as the input PDF are discussed. Then, the deep inelastic proton structure functions, F2(x,Q2), are calculated from the above UPDF in the two schemes, and compared with the data, which are extracted from the ZEUS, NMC, and H1+ZEUS experimental measurements. In general, it is shown that the calculated structure functions based on the UPDF of two schemes, are consistent to the experimental data, and by a good approximation, they are independent to the input PDF. But the proton structure functions, which are extracted from the KMR prescription, have better agreement to the data with respect to that of MRW. Although the MRW formalism is in more compliance with the Dokshitzer-Bribov-Lipatov-Altarelli-Parisi (DGLAP) evolution equation requisites, but it seems in the KMR case, the angular ordering constraint spreads the UPDF to the whole transverse momentum region, and makes the results to sum up the leading DGLAP and Balitski-Fadin-Kuraev-Lipatov (BFKL) Logarithms. This point is under study by the authors.

  17. Racism and the older voter? Arizona's rejection of a paid holiday to honor Martin Luther King.

    PubMed

    Kastenbaum, R

    1991-01-01

    Two propositions that would have established a paid Martin Luther King holiday were defeated in Arizona's statewide elections of November 6, 1990. Communities and counties with high proportions of senior adult voters cast proportionately more votes against these propositions. Was this an example of racism among the primarily anglo senior adult voters of Arizona? Three models were proposed to account for the general pattern of election-related behavior as well as the vote itself: 1) proactive racist, 2) pragmatic self-interest, and 3) fortress mentality. It was suggested that proactive racism and pragmatic self-interest accounted for less of the opposition to a paid holiday honoring Martin Luther King than did a fortress mentality that has developed through a combination of circumstances. Attention is also given to the larger question of senior adults as perpetrators as well as victims of bigotry.

  18. Social marketing and MARTIN: tools for organizing, analyzing, and interpreting qualitative data.

    PubMed

    Higgins, J W

    1998-11-01

    The purpose of this article is to discuss how the computer software program MARTIN and social marketing concepts (understanding the consumer perspective, exchange, marketing mix, and segmentation) were used as organizational, analytical, and interpretive tools for qualitative data. The qualitative data are from a case study on citizen participation in a health reform policy in British Columbia. The concept of broad-based public participation is a fundamental element of health promotion and citizenship. There is a gap, however, between the promise and reality of citizen participation in health promotion. Emerging from the analysis was an understanding of the societal circumstances that inhibited or fostered participation. This article describes how the code-based, theory-building attributes of the MARTIN software facilitated a new conceptualization of participatory citizenship and generated new insights into understanding why some people participate and others do not.

    Gold mining is responsible for most Hg pollution in developing countries. The aims of this study were to assess the levels of total Hg (T-Hg) in human hair, fish, water, macrophyte, and sediment samples in the gold mining district of San Martin de Loba, Colombia, as well as to determine fish consumption-based risks for T-Hg ingestion. T-Hg levels were measured by electrothermal atomization and atomic absorption spectroscopy. The overall mean T-Hg level in hair for humans in the mining district of San Martin de Loba was 2.12 μg/g, whereas for the reference site, Chimichagua, Cesar, it was 0.58 μg/g. Mean T-Hg levels were not different when considered within localities belonging to the mining district but differed when the comparison included Chimichagua. T-Hg levels in examined locations were weakly but significantly associated with age and height, as well as with fish consumption, except in San Martin de Loba. High T-Hg concentrations in fish were detected in Pseudoplatystoma magdaleniatum, Caquetaia kraussii, Ageneiosus pardalis, Cyrtocharax magdalenae, and Triportheus magdalenae, whereas the lowest appeared in Prochilodus magdalenae and Hemiancistrus wilsoni. In terms of Hg exposure due to fish consumption, only these last two species offer some guarantee of low risk for Hg-related health problems. Water, floating macrophytes, and sediments from effluents near mining sites also had high Hg values. In mines of San Martin de Loba and Hatillo de Loba, for instance, the geoaccumulation index (I(geo)) for sediments reached values greater than 6, indicating extreme pollution. In short, these data support the presence of a high Hg-polluted environment in this mining district, with direct risk for deleterious effects on the health of the mining communities.

    The design of the barrel baffle of the Infrared Astronomical Satellite (IRAS) Optical Subsystem to minimize production of particulate contamination is described. The configuration of the 50-inch long, 28.5-inch diameter baffle required pop-rivet assembly after coating with Martin Optical Black for stray light suppression. An experiment to determine the contamination produced at assembly led to the modification of the baffle construction to preclude such damage to the coated surfaces.

The ethnic make up is almost all black African with some British, Portuguese, and Lebanese. The religions are primarily Anglican, with evangelical Protestant and Catholic minorities. Infant mortality stands at 41/1000. The government is a constitutional monarchy with a Westminster type parliament. There is a governor, a prime minister, a cabinet, an 11 -member appointed upper house and a 11- member elected house of representatives. The gross national product is $83 million and the annual growth rate is 4.6%. There are no natural resources, and agricultural products include sugarcane, cotton, peanuts, and vegetables. Industry is made up of manufacturing 12.9%, transport and communications 13%, construction 9.1% and hotels and restaurants 4.5%. The Federation of St. Kitts and Nevis became independent in 1983. The government diversified the agriculture by planting other crops than sugar, producing gelled ethanol, and developing a cane spirits liquor. Tourism has grown the most and in 1987 passed sugar as the main source of income. International aid will assist in finishing a road that will open the southeast area of St. Kitts for construction of hotels, where some of the best beaches are located.

  8. Mount St. Helens Rebirth

    2002-01-01

    The catastrophic eruption of Mt. St. Helens 20 years ago today (on May 18, 1980), ranks among the most important natural events of the twentieth century in the United States. Because Mt. St. Helens is in a remote area of the Cascades Mountains, only a few people were killed by the eruption, but property damage and destruction totaled in the billions of dollars. Mount St. Helens is an example of a composite or stratovolcano. These are explosive volcanoes that are generally steep-sided, symmetrical cones built up by the accumulation of debris from previous eruptions and consist of alternating layers of lava flows, volcanic ash and cinder. Some of the most photographed mountains in the world are stratovolcanoes, including Mount Fuji in Japan, Mount Cotopaxi in Ecuador, Mount Hood in Oregon, and Mount Rainier in Washington. The recently erupting Mount Usu on the island of Hokkaido in Japan is also a stratovolcano. Stratovolcanoes are characterized by having plumbing systems that move magma from a chamber deep within the Earth's crust to vents at the surface. The height of Mt. St. Helens was reduced from about 2950 m (9677 ft) to about 2550 m (8364 ft) as a result of the explosive eruption on the morning of May 18. The eruption sent a column of dust and ash upwards more than 25 km into the atmosphere, and shock waves from the blast knocked down almost every tree within 10 km of the central crater. Massive avalanches and mudflows, generated by the near-instantaneous melting of deep snowpacks on the flanks of the mountain, devastated an area more than 20 km to the north and east of the former summit, and rivers choked with all sorts of debris were flooded more than 100 km away. The area of almost total destruction was about 600 sq. km. Ash from the eruption cloud was rapidly blown to the northeast and east producing lightning which started many small forest fires. An erie darkness caused by the cloud enveloped the landscape more than 200 km from the blast area, and ash

    Martin Ryle was a pioneer of radio astronomy, who developed observational techniques that took the subjectfrom the simple detection of solar radio waves to the most important cosmological investigations since Hubble's discoveries of the 1920s. His involvement with radar during World War II aroused an interest in aerial systems and receiver techniques that eventually led to the invention of aperture synthesis, a technique that is now the basis of all high angular resolution observations in radio astronomy. Using aperturesynthesis telescopes at Cambridge he gave conclusive evidence of evolution in the large-scale structure of the Universe, disproved the steady state theory, and laid the foundations for modern observational cosmology.

    We calculated the population density of the critically endangered Callicebus oenanthe in the Ojos de Agua Conservation Concession, a dry forest area in the department of San Martin, Peru. Results showed significant differences (p < 0.01) in group densities between forest boundaries (16.5 groups/km2, IQR = 21.1-11.0) and forest interior (4.0 groups/km2, IQR = 5.0-0.0), suggesting the 2,550-ha area harbours roughly 1,150 titi monkeys. This makes Ojos de Agua an important cornerstone in the conservation of the species, because it is one of the largest protected areas where the species occurs.

    The portrayal of self-medication and drug use was studied in three films by Martin Scorsese: Raging Bull (1980), Goodfellas (1990) and The Departed (2006). Self-medication using nicotine in Raging Bull, cocaine in Goodfellas and sedatives in The Departed, exhibit mixed portrayals of the self-medication hypothesis. The temporal aspects of the hypothesis and credibility of character psychopathology show variation between the films. Across all films, the selection of particular drugs of choice for certain symptom clusters is consonant with that detailed in the self-medication hypothesis put forward by Khantzian.

    On May 18, 1980, Mount St. Helens, Washington exploded in a spectacular and devastating eruption that shocked the world. The eruption, one of the most powerful in the history of the United States, removed 2.7 cubic kilometers of rock from the volcano's edifice, the bulk of which had been constructed by nearly 4,000 years of lava-dome-building eruptions. In seconds, the mountain's summit elevation was lowered from 2,950 meters to 2,549 meters, leaving a north-facing, horseshoe-shaped crater over 2 kilometers wide. Following the 1980 eruption, Mount St. Helens remained active. A large lava dome began episodically extruding in the center of the volcano's empty crater. This dome-building eruption lasted until 1986 and added about 80 million cubic meters of rock to the volcano. During the two decades following the May 18, 1980 eruption, Crater Glacier formed tongues of ice around the east and west sides of the lava dome in the deeply shaded niche between the lava dome and the south crater wall. Long the most active volcano in the Cascade Range with a complex 300,000-year history, Mount St. Helens erupted again in the fall of 2004 as a new period of dome building began within the 1980 crater. Between October 2004 and February 2006, about 80 million cubic meters of dacite lava erupted immediately south of the 1980-86 lava dome. The erupting lava separated the glacier into two parts, first squeezing the east arm of the glacier against the east crater wall and then causing equally spectacular crevassing and broad uplift of the glacier's west arm. Vertical aerial photographs document dome growth and glacier deformation. These photographs enabled photogrammetric construction of a series of high-resolution digital elevation models (DEMs) showing changes from October 4, 2004 to February 9, 2006. From the DEMs, Geographic Information Systems (GIS) applications were used to estimate extruded volumes and growth rates of the new lava dome. The DEMs were also used to quantify dome

    This Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) image of Mt. St. Helens volcano in Washington State was acquired on August 8, 2000 and covers an area of 37 by 51 km. Mount Saint Helens, a volcano in the Cascade Range of southwestern Washington that had been dormant since 1857, began to show signs of renewed activity in early 1980. On 18 May 1980, it erupted with such violence that the top of the mountain was blown off, spewing a cloud of ash and gases that rose to an altitude of 19 kilometers. The blast killed about 60 people and destroyed all life in an area of some 180 square kilometers (some 70 square miles), while a much larger area was covered with ash and debris. It continues to spit forth ash and steam intermittently. As a result of the eruption, the mountain's elevation decreased from 2,950 meters to 2,549 meters. The simulated fly-over was produced by draping ASTER visible and near infrared image data over a digital topography model, created from ASTER's 3-D stereo bands. The color was computer enhanced to create a 'natural' color image, where the vegetation appears green. The topography has been exaggerated 2 times to enhance the appearance of the relief.

    In order to face the challenges in healthcare this century, it is essential that surgeons understand modern leadership principles. One of the greatest leaders in history was Dr. Martin Luther King, Jr., who provides a shining example of level-5 leadership for us to study. The study of leadership principles of great leaders can provide us with practical methods of conflict resolution as well as inspiration to keep us engaged and focused. As leaders of the medical community, we face numerous challenges, including discovering and implementing new treatments for disease, providing care for the indigent, overcoming educational challenges such as incorporating the ACGME Core Competencies into our surgical training and promoting diversity in education. Achieving these goals is often hindered by the environment in which we labor-nearly 50 million are uninsured, the rising cost of medical care is currently at 16% of the GNP, and reimbursement rates are falling-which makes the practice of surgery a significant challenge. Effective leadership will be paramount in achieving these goals. In this editorial, which summarizes a presentation given to the Surgical Section of the annual National Medical Association meeting, five important leadership principles that are important for surgeons have been selected and related to the outstanding leadership of Dr. Martin Luther King, Jr. Images Figure 1 Figure 2 Figure 3 Figure 4 Figure 5 Figure 6 PMID:17304963

    Following Martin [Martin PS (1973) Science 179:969-974], we propose the hypothesis that the timing of human arrival to the New World can be assessed by examining the ecological impacts of a small population of people on extinct Pleistocene megafauna. To that end, we compiled lists of direct radiocarbon dates on paleontological specimens of extinct genera from North and South America with the expectation that the initial decline of extinct megafauna should correspond in time with the initial evidence for human colonization and that those declines should occur first in eastern Beringia, next in the contiguous United States, and last in South America. Analyses of spacings and frequency distributions of radiocarbon dates for each region support the idea that the extinction event first commenced in Beringia, roughly 13,300-15,000 BP. For the United States and South America, extinctions commenced considerably later but were closely spaced in time. For the contiguous United States, extinction began at ca. 12,900-13,200 BP, and at ca. 12,600-13,900 BP in South America. For areas south of Beringia, these estimates correspond well with the first significant evidence for human presence and are consistent with the predictions of the overkill hypothesis.

    In order to face the challenges in healthcare this century, it is essential that surgeons understand modern leadership principles. One of the greatest leaders in history was Dr. Martin Luther King, Jr., who provides a shining example of level-5 leadership for us to study. The study of leadership principles of great leaders can provide us with practical methods of conflict resolution as well as inspiration to keep us engaged and focused. As leaders of the medical community, we face numerous challenges, including discovering and implementing new treatments for disease, providing care for the indigent, overcoming educational challenges such as incorporating the ACGME Core Competencies into our surgical training and promoting diversity in education. Achieving these goals is often hindered by the environment in which we labor-nearly 50 million are uninsured, the rising cost of medical care is currently at 16% of the GNP, and reimbursement rates are falling-which makes the practice of surgery a significant challenge. Effective leadership will be paramount in achieving these goals. In this editorial, which summarizes a presentation given to the Surgical Section of the annual National Medical Association meeting, five important leadership principles that are important for surgeons have been selected and related to the outstanding leadership of Dr. Martin Luther King, Jr.

  1. Wake structure and wingbeat kinematics of a house-martin Delichon urbica.

    The wingbeat kinematics and wake structure of a trained house martin in free, steady flight in a wind tunnel have been studied over a range of flight speeds, and compared and contrasted with similar measurements for a thrush nightingale and a pair of robins. The house martin has a higher aspect ratio (more slender) wing, and is a more obviously agile and aerobatic flyer, catching insects on the wing. The wingbeat is notable for the presence at higher flight speeds of a characteristic pause in the upstroke. The essential characteristics of the wing motions can be reconstructed with a simple two-frequency model derived from Fourier analysis. At slow speeds, the distribution of wake vorticity is more simple than for the other previously measured birds, and the upstroke does not contribute to weight support. The upstroke becomes gradually more significant as the flight speed increases, and although the vortex wake shows a signature of the pause phase, the global circulation measurements are otherwise in good agreement with surprisingly simple aerodynamic models, and with predictions across the different species, implying quite similar aerodynamic performance of the wing sections. The local Reynolds numbers of the wing sections are sufficiently low that the well-known instabilities of attached laminar flows over lifting surfaces, which are known to occur at two to three times this value, may not develop.

  2. Parasitism, immune response and reproductive success in the house martin Delichonurbica.

    Parasites often exert strong selection pressures on their hosts that have evolved anti-parasite defences to counter the negative effects of parasites. We studied the relationship between intensity of parasitism, one aspect of host immune response, and host reproductive success, using the house martin bug Oeciacushirundinis and its house martin Delichonurbica host as a model system. Experimental manipulation of parasite load of nests during laying of the first clutch altered the intensity of parasitism. Parasites reduced the reproductive success of their hosts measured in terms of body condition and survival of nestlings. Host immune response, measured as the concentration of gammaglobulins and total plasma proteins, was positively associated with parasite reproduction, estimated as the number of juvenile parasites, but was only weakly related to the intensity of adult parasites. The concentration of gammaglobulins was negatively related to nestling body mass, implying a trade-off between immune function and body condition. Parasite reproduction thus exerts a cost on hosts by increasing the immune response.

    The bioassay code DOSEXPRT was developed for Martin Marietta Energy Systems, Inc., to provide compliance with Department of Energy (DOE) Order 5480, Chapter 11. DOSEXPRT computes the intake of a radionuclide in any year (considering both acute and chronic intakes) from in vivo measurements of the retained activity and/or measurements of the activity in excreta. The committed effective and organ doses for the intake are computed as well as the effective and organ doses expected to be received in each calendar year out to 50 years beyond the year of intake. The bioassay records used as input for DOSEXPRT are extracted from the Martin Marietta Energy Systems Occupational Health Information System (OHIS). DOSEXPRT implements a set of algorithms with parameters governing the translocation, retention, and excretion of the nuclide contained in data files specific to the nuclide. These files also contain dose-per-unit-intake coefficients used to compute the committed dose equivalent for the intakes in the year. Annual organ and effective doses are computed using additional dose-rate files that contain data on the dose rate at various times following a unit intake. If measurements are presented for more than one assay for a given nuclide, DOSEXPRT estimates the intake by applying weights assigned in the nuclide file for each assay. DOSEXPRT is accessed off the OHIS MENU No. 4 and designed to be run as a batch processor, but can also be run interactively for testing purposes.

    This 3-D anaglyph image of Mt. St. Helens volcano combines the nadir-looking and back-looking band 3 images of ASTER. To view the image in stereo, you will need blue-red glasses. Make sure to look through the red lens with your left eye. Figure 1: This ASTER image of Mt. St. Helens volcano in Washington was acquired on August 8, 2000 and covers an area of 37 by 51 km. Mount Saint Helens, a volcano in the Cascade Range of southwestern Washington that had been dormant since 1857, began to show signs of renewed activity in early 1980. On 18 May 1980, it erupted with such violence that the top of the mountain was blown off, spewing a cloud of ash and gases that rose to an altitude of 19 kilometers. The blast killed about 60 people and destroyed all life in an area of some 180 square kilometers (some 70 square miles), while a much larger area was covered with ash and debris. It continues to spit forth ash and steam intermittently. As a result of the eruption, the mountain's elevation decreased from 2,950 meters to 2,549 meters. The image is centered at 46.2 degrees north latitude, 122.2 degrees west longitude.

    Movie: The simulated fly-over was produced by draping ASTER visible and near infrared image data over a digital topography model, created from ASTER's 3-D stereo bands. The color was computer enhanced to create a natural color image, where the vegetation appears green. The topography has been exaggerated 2 times to enhance the appearance of the relief.

    At the end of 2013, chikungunya virus (CHIKV) emerged in Saint Martin Island, Caribbean. The Asian lineage was identified. Seven months after this introduction, the seroprevalence was 16.9% in the population of Saint Martin and 39.0% of infections remained asymptomatic. This moderate attack rate and the apparent limited size of the outbreak in Saint Martin could be explained by control measures involved to lower the exposure of the inhabitants. Other drivers such as climatic factors and population genetic factors should be explored. The substantial rate of asymptomatic infections recorded points to a potential source of infection that can both spread in new geographic areas and maintain an inconspicuous endemic circulation in the Americas.

    Sandia national laboratories (SNL) and lockheed martin MS2 are designing an electromagnetic missile launcher (EMML) for naval applications. The EMML uses an induction coilgun topology with the requirement of launching a 3600 lb. missile up to a velocity of 40 m/s. To demonstrate the feasibility of the electromagnetic propulsion design, a demonstrator launcher was built that consists of approximately 10% of the propulsion coils needed for a tactical design. The demonstrator verified the design by launching a 1430 lb weighted sled to a height of 24 ft in mid-December 2004 (Figure 1). This paper provides the general launcher design, specific pulsed power system component details, system operation, and demonstration results.

    The holotype of Libellulosoma minuta, until now regarded as the unique specimen of this monotypic genus and considered lost for half a century, was found again in the dragonfly collection of the Muséum National d'Histoire Naturelle in Paris. A second specimen, also from Madagascar (probably East Madagascar) was found in the collection René Martin together with the holotype. A redescription, including the structure of the secondary copulatory apparatus, is provided. The genus Libellulosoma is closely related to the genera Pentathemis and Aeschnosoma, and its membership in the clade Aeschnosomata is well supported. Evidence from biogeography, the fossil record, and phylogeny indicates that this group, possible sister group of remaining Corduliidae s.s., was probably already present in the Early Cretaceous.

    1977-01-01

    Urban growth has been rapid in recent years in Palm Beach and Martin Counties, Fla. The withdrawal of large quantities of fresh ground water in the vicinity of the coast has reduced or locally reversed the natural seaward hydraulic gradient and, in places, allowed saltwater to advance landward in the aquifer, displacing freshwater. Maps show the position of the saltwater front in eight urban areas adjacent to the coast. The saltwater front, as shown on the profiles, is based on a chloride concentration of 250 mg/liter which is recommended as a limit for water that is considered potable. The chloride concentration of native freshwater almost always is less than 50 mg/liter in the coastal aquifer. (Woodard-USGS)

    D'Arcy Martin is a labor educator in Toronto. He started his career in adult education and made the transition to labor educator. He has been the Canadian education director for Steelworkers, Communications Workers, and the merged Communications, Energy and Paperworkers Union. He is also coordinator of the Centre for the Study of Education and Work at the University of Toronto, which brings together academics and unionists to research the informal learning of workers. In the following interview, D'Arcy talked about his experiences as a Canadian labor educator, how being an internationalist has influenced his views, and how the dynamics of power influence not only workers and their unions, but educators, too. D'Arcy described his work as "being on the web … to go sideways, that is, to draw connections, including international ones, amongst people of like mind and to build collective power by inviting people to learn together."

    Lockheed Martin is developing concepts for safe, affordable Two Stage to Orbit (TSTO) reusable launch vehicles as part of NASA s Space Launch Initiaiive. This paper discusses the options considered for the design of the TSTO, the impact of each of these options on the vehicle configuration, the criteria used for selection of preferred configurations, and the results of the selection process. More than twenty configurations were developed in detail in order to compare optioiis such as propellant choice, serial vs. parallel burn sequence, use of propellant crossfeed between stages, bimese or optimized stage designs, and high or low staging velocities. Each configuration was analyzed not only for performance and sizing, but also for cost and reliability. The study concluded that kerosene was the superior fuel for first stages, and that bimese vehicles were not attractive.

    Because of its high prevalence, HIV in pregnancy is a major public health issue in French Guyana and Saint Martin, particularly since the risk of transmission to the child can be significantly reduced through pharmacological treatment. Most of the HIV-infected women in these areas are immigrants living in highly precarious circumstances. This study examines the capacity of the healthcare system to adapt to the specific social characteristics of overseas regions, focusing in particular on perceptions of the risks associated with pregnancy among HIV-infected women and the social inequalities affecting adherence to HIV treatment. Semi-structured interviews were conducted in Cayenne, Saint-Laurent du Maroni and Saint-Martin with 19 HIV-infected women and 54 social and health care professionals. Observations (medical consultations, therapeutic education consultations, discussion groups, medical meetings) were also conducted to complete the data set. The results show that professionals tend to use the most significant concern expressed by HIV-infected women - i.e. the risk of transmitting their infection to their child - as an opportunity to promote the active involvement of patients in their own care and the health care of their children by encouraging them to adhere to their treatment. The study found that professionals seek to lessen the impact of social inequalities on patient adherence to the treatment in a context of social stigmatization linked to the particular status of their patients as HIV-infected women, undocumented migrants, and ethnic minority members. The example of HIV in pregnancy illustrates the capacity of the healthcare system to reduce the impact of social inequalities on health and highlights the significant negative impact that a reduced commitment to this issue would have.

    The Schedule Organizer, SO (COSMIC Program MSC-21525), Schedule Tracker, ST, and Schedule Report Generator, SRG (COSMIC Program MSC-21527), are programs that manipulate data base files in ways that are advantageous to scheduling applications. Originally designed for the Space Shuttle flight schedule, the program can be easily modified for other scheduling situations. Schedule Organizer provides a simple method for generating distribution lists. These distribution lists contain readers' names for each task schedule defined by the input files. Schedule Tracker provides an effective method for tracking tasks that are 'past due' and/or 'near term'. ST generates reports for each responsible staff member with one or more assigned tasks that fall within the two listed categories. This enables an engineering manager to monitor tasks assigned to staff by running ST on a weekly basis. ST only lists tasks on reports that have become past due or are scheduled for recent completion (near term). Schedule Report Generator provides a simple method for generating periodic schedule reports. ST and SRG use the same data base file as input. The common data base file has a maximum number of 400 entries. The time span of all three programs is nineteen months. Both of these maximum numbers can be modified by the user. ST requires the VMS Operating System on DEC VAX and was written in PL/1 and DEC Command Language (DCL). The program requires a memory of 233KB. ST can be purchased separately or in a package (COSMIC Program COS-10021) containing SO, ST, and SRG. ST was developed in 1985.

    1995-06-01

    T.U. Electric`s Martin Lake plant has a history of boiler slagging which is characteristic of the Texas lignite used as fuel. Using the capabilities of EPRI`s Plant Monitoring Workstation (PMW) and enhanced performance monitoring instrumentation, Martin Lake has developed an on-line boiler cleanliness model that can be used to manage sootblowing. Testing of the model has been very positive, showing good correlation between blowers operated and cleanliness obtained. potential applications of this model are for (1) testing the effectiveness of revised combustion strategies and (2) development of an automatic sootblowing system. These two areas could result in heat rate improvements. This paper discusses how the PMW models were configured to represent Martin Lake`s boilers and the results of on-line tests. Critical to this technique is the calculation of boiler gas flow. A somewhat unique feature of Martin Lake`s model is the calculation of boiler gas flow based on the induction draft (ID) fan horsepower. Most boiler gas flow calculations are based on stack gas flow which would have been inaccurate because of the wet scrubbers and stack gas reheat on this unit. Using the ID fan horsepower to derive boiler gas flow has application in boiler efficiency calculations as well.

    This Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) image of Mount St. Helens was captured one week after the March 8, 2005, ash and steam eruption, the latest activity since the volcano's reawakening in September 2004. The new lava dome in the southeast part of the crater is clearly visible, highlighted by red areas where ASTER's infrared channels detected hot spots from incandescent lava. The new lava dome is 155 meters (500 feet) higher than the old lava dome, and still growing.

    With its 14 spectral bands from the visible to the thermal infrared wavelength region, and its high spatial resolution of 15 to 90 meters (about 50 to 300 feet), ASTER images Earth to map and monitor the changing surface of our planet.

    ASTER is one of five Earth-observing instruments launched December 18, 1999, on NASA's Terra satellite. The instrument was built by Japan's Ministry of Economy, Trade and Industry. A joint U.S./Japan science team is responsible for validation and calibration of the instrument and the data products.

    The broad spectral coverage and high spectral resolution of ASTER provides scientists in numerous disciplines with critical information for surface mapping, and monitoring of dynamic conditions and temporal change. Example applications are: monitoring glacial advances and retreats; monitoring potentially active volcanoes; identifying crop stress; determining cloud morphology and physical properties; wetlands evaluation; thermal pollution monitoring; coral reef degradation; surface temperature mapping of soils and geology; and measuring surface heat balance.

    This is an artist's conception of the proposed NASA/Lockheed Martin Single-Stage-To-Orbit (SSTO) Reusable Launch Vehicle (RLV) docking with the International Space Station. NASA's Dryden Flight Research Center, Edwards, California, expected to play a key role in the development and flight testing of the X-33, which was a technology demonstrator vehicle for the proposed RLV. The RLV technology program was a cooperative agreement between NASA and industry. The goal of the RLV technology program was to enable significant reductions in the cost of access to space, and to promote the creation and delivery of new space services and other activities that would have improved U.S. economic competitiveness. The X-33 was a wedged-shaped subscale technology demonstrator prototype of a potential future Reusable Launch Vehicle (RLV) that Lockheed Martin had dubbed VentureStar. The company had hoped to develop VentureStar early this century. Through demonstration flight and ground research, NASA's X-33 program was to have provided the information needed for industry representatives such as Lockheed Martin to decide whether to proceed with the development of a full-scale, commercial RLV program. A full-scale, single-stage-to-orbit RLV was to have dramatically increased reliability and lowered the cost of putting a pound of payload into space, from the current figure of $10,000 to $1,000. Reducing the cost associated with transporting payloads in Low Earth Orbit (LEO) by using a commercial RLV was to have created new opportunities for space access and significantly improved U.S. economic competitiveness in the world-wide launch marketplace. NASA expected to be a customer, not the operator, of the commercial RLV. The X-33 design was based on a lifting body shape with two revolutionary 'linear aerospike' rocket engines and a rugged metallic thermal protection system. The vehicle also was to have lightweight components and fuel tanks built to conform to the vehicle's outer shape. Time

    A new thermal-vacuum facility has been recently completed at the Martin Marietta Waterton plant near Denver, Colorado. The facility was designed, fabricated, installed, and tested as a turn-key project by Pitt-Des Moines Inc. and CVI Inc. The chamber has a 5.49 M by 6.10 M (18 ft by 20 ft) flat floor and a half-cylindrical roof with a diameter of 5.49 M (18 ft). Both ends of the chamber have full cross section doors, with one equipped with translating motors for horizontal motion. The chamber is provided with four 0.91 M (36 inches) cryopumps to obtain an ultimate pressure of 9 x 10(exp -8) Torr (Clean-Dry-Empty). The thermal shroud is designed to operate at a maximum of -179 C (-290 F) with an internal heat input of 316 MJ/Hr (300,000 BTU/Hr) using liquid nitrogen. The shroud is also designed to operate at any temperature between -156 C (-250 F) and 121 C (+250 F) using gaseous nitrogen, and heat or cool at a rate of 1.1 C (2 F) per minute.

  12. On the Performance of the Martin Digital Filter for High- and Low-pass Applications

    1979-01-01

    A nonrecursive numerical filter is described in which the weighting sequence is optimized by minimizing the excursion from the ideal rectangular filter in a least squares sense over the entire domain of normalized frequency. Additional corrections to the weights in order to reduce overshoot oscillations (Gibbs phenomenon) and to insure unity gain at zero frequency for the low pass filter are incorporated. The filter is characterized by a zero phase shift for all frequencies (due to a symmetric weighting sequence), a finite memory and stability, and it may readily be transformed to a high pass filter. Equations for the filter weights and the frequency response function are presented, and applications to high and low pass filtering are examined. A discussion of optimization of high pass filter parameters for a rather stringent response requirement is given in an application to the removal of aircraft low frequency oscillations superimposed on remotely sensed ocean surface profiles. Several frequency response functions are displayed, both in normalized frequency space and in period space. A comparison of the performance of the Martin filter with some other commonly used low pass digital filters is provided in an application to oceanographic data.

    One of the highest honors of one's career is to be asked to address colleagues, mentors, and students who represent the world's leading health professionals dedicated to reducing the morbidity and mortality associated with head and neck cancer. Hayes Martin would certainly share this feeling of honor and humility in having a lecture given in his name on the occasion of the Eighth International Conference on Head and Neck Cancer. I am so very pleased to share with you some thoughts on the assessment, adequacy, and application of surgical resection margins in an era in which personalized surgery and molecular medicine will have a major impact on patient outcomes. My thoughts about surgical margins have evolved over nearly 40 years of performing surgical resections for cancer. A discussion of margins may seem somewhat mundane to many of you; however, I hope to provide a futuristic and somewhat theoretical view of how surgical margin issues will relate to the personalization of modern head and neck cancer treatment and how the biology of the tumor microenvironment may be instructive in the application of our surgical approaches. This is particularly relevant because of the rapid expansion of functional surgical approaches utilizing minimally invasive endoscopic resections and robotic techniques that may not achieve the same wide oncologic margins that have been emphasized historically.(1,2) Proper selection of patients for such procedures is critical if we are to improve overall treatment results.

    To augment the capabilities of the Space Transportation System, NASA has funded studies and developed programs aimed at developing reusable, remotely piloted spacecraft and satellite servicing systems capable of delivering, retrieving, and servicing payloads at altitudes and inclinations beyond the reach of the present Shuttle Orbiters. Since the mid 1970's, researchers at the Martin Marietta Astronautics Group Space Operations Simulation (SOS) Laboratory have been engaged in investigations of remotely piloted and supervised autonomous spacecraft operations. These investigations were based on high fidelity, real-time simulations and have covered a wide range of human factors issues related to controllability. Among these are: (1) mission conditions, including thruster plume impingements and signal time delays; (2) vehicle performance variables, including control authority, control harmony, minimum impulse, and cross coupling of accelerations; (3) maneuvering task requirements such as target distance and dynamics; (4) control parameters including various control modes and rate/displacement deadbands; and (5) display parameters involving camera placement and function, visual aids, and presentation of operational feedback from the spacecraft. This presentation includes a brief description of the capabilities of the SOS Lab to simulate real-time free-flyer operations using live video, advanced technology ground and on-orbit workstations, and sophisticated computer models of on-orbit spacecraft behavior. Sample results from human factors studies in the five categories cited above are provided.

    An evaluation of the Martin Marietta Energy Systems, Inc., personnel dosimeter to radiation incident from non-perpendicular angles was carried out to meet the Department of Energy Laboratory Accreditation Program (DOELAP) requirements. Dosimeters were exposed to six different radiation sources. For each source, dosimeters were rotated about their horizontal and vertical axes at seven different angles each. Raw readings were processed through the dose calculation algorithm used for routine personnel dosimetry to determine dose equivalent values. Dose equivalent responses relative to zero degree incident angle were found to be within {plus_minus} 20% for M150, K-59 and {sup 137}Cs photons when the incident angle was 60{degree} or less. For low-energy photon irradiations (M30 and K-16), responses for angles other than perpendicular incidence are generally unpredictable. Reasons include: (1) failure of dose calculation algorithm to identify the radiation field correctly due to unusual element ratios; and (2) at extreme angles ({plus_minus} 85{degree}), the dosimeter design (in relation to the irradiation geometry) becomes the limiting factor in producing reproducible results. Response to {sup 204}Tl beta particles decreases rapidly with increasing angle of incidence.

    In response to a confidential request, worker exposures to arsenic were evaluated in the uranium enrichment process of the Lockheed Martin Utility Systems, Inc. (SIC-2819) gaseous diffusion facility in Portsmouth, Ohio. An industrial hygiene survey was conducted and area air samples analyzed for uranium and radon. Sampling for arsenic was conducted in the process building, and during welding on equipment removed from the process. Time weighted average exposure levels for seven area samples ranged from nondetectable to 0.7 microgram/cubic meter arsenic. Personal breathing zone samples from 14 workers ranged from nondetectable to 109 micrograms/cubic meter arsenic. All six of the workers who had personal breathing zone samples with detectable arsenic levels wore protective clothing and supplied air respirators. Time weighted average exposures to total uranium were well below the NIOSH recommended exposure limit of 2 micrograms/cubic meter. The author concludes that there was a potential for worker exposure to arsenic during maintenance activities on uranium enrichment equipment; workers performing these activities used protective clothing and respiratory protection.

    In September 2008, the U.S. Department of Energy and Martin County Economic Development Corporation entered into an agreement to further the advancement of a microtubular PEM fuel cell developed by Microcell Corporation. The overall focus of this project was on research and development related to high volume manufacturing of fuel cells and cost reduction in the fuel cell manufacturing process. The extrusion process used for the microfiber fuel cells in this project is inherently a low cost, high volume, high speed manufacturing process. In order to take advantage of the capabilities that the extrusion process provides, all subsequent manufacturing processes must be enhanced to meet the extrusion line’s speed and output. Significant research and development was completed on these subsequent processes to ensure that power output and performance were not negatively impacted by the higher speeds, design changes and process improvements developed in this project. All tasks were successfully completed resulting in cost reductions, performance improvements and process enhancements in the areas of speed and quality. These results support the Department of Energy’s goal of fuel cell commercialization.

    The Morphing Aircraft Structures (MAS) program is a Defense Advanced Research Projects Agency (DARPA) led effort to develop morphing flight vehicles capable of radical shape change in flight. Two performance parameters of interest are loiter time and dash speed as these define the persistence and responsiveness of an aircraft. The geometrical characteristics that optimize loiter time and dash speed require different geometrical planforms. Therefore, radical shape change, usually involving wing area and sweep, allows vehicle optimization across many flight regimes. The second phase of the MAS program consisted of wind tunnel tests conducted at the NASA Langley Transonic Dynamics Tunnel to demonstrate two morphing concepts and their enabling technologies with large-scale semi-span models. This paper will focus upon one of those wind tunnel tests that utilized a model developed by Lockheed Martin Aeronautics Company (LM). Wind tunnel success criteria were developed by NASA to support the DARPA program objectives. The primary focus of this paper will be the demonstration of the DARPA objectives by systematic evaluation of the wind tunnel model performance relative to the defined success criteria. This paper will also provide a description of the LM model and instrumentation, and document pertinent lessons learned. Finally, as part of the success criteria, aeroelastic characteristics of the LM derived MAS vehicle are also addressed. Evaluation of aeroelastic characteristics is the most detailed criterion investigated in this paper. While no aeroelastic instabilities were encountered as a direct result of the morphing design or components, several interesting and unexpected aeroelastic phenomenon arose during testing.

    From the time he became chef de service at La Salpêtrière Hospital in 1866 until his death in 1893, Jean-Martin Charcot oversaw 32 house officers. Some of them became famous, such as D.M. Bourneville, E. Brissaud, P. Marie and G. Gilles de la Tourette. Others are less well known. The fact remains that Charcot knew how to surround himself with fine students and leverage their talents in order to make the neurological discoveries by which he would become famous throughout the world. Here, we present the biographies of H. Soulier (1862), J. Cotard (1865), R. Lépine (1867), A. Gombault (1872), A. Pierret (1874), A. Pitres (1876), P. Oulmont (1877), G. Guinon (1885), P. Blocq(1887), E. Huet (1888), E. Parmentier (1890) and A. Souques(1893). Each of these men with their unique paths and interests helped lay the foundations for the birth of neurology at the end of the 19th century in Paris. As Emile Littré said: 'La science de la Médecine, si elle ne veut pas être rabaissée au rang de métier, doit s'occuper de son histoire et soigner les vieux monuments que les temps passés lui ont légués', which could be translated as 'to avoid being reduced to a trade, the science of medicine must attend to its history and take care of the old monuments handed down by time'.

    Jean-Martin Charcot (1825-93) was a well-known French neurologist. Although he is widely recognized for his discovery of several neurological disorders and his research into aphasia, Charcot's ideas about how the brain processes music are less well known. Charcot discussed the music abilities of several patients in the context of his 'Friday Lessons' on aphasia, which took place at the Salpêtrière Hospital in Paris in 1883-84. In his most comprehensive discussion about music, Charcot described a professional trombone player who developed difficulty copying music notation and playing his instrument, thereby identifying a new isolated syndrome of music agraphia without aphasia. Because the description of this case was published only in Italian by one of his students, Domenico Miliotti, there has been considerable confusion and under-acknowledgement of Charcot's ideas about music and the brain. In this paper, we describe Charcot's ideas regarding music and place them within the historical context of the growing interest in the neurological underpinnings of music abilities that took place in the 1880s.

    The Middle Pennsylvanian (Westphalian D) Stockton (also known as the Broas) coal bed of the Breathitt Formation is an important energy resource in Kentucky. Petrographic, geochemical and palynologic studies were undertaken from mine, core and highway exposures in Martin and northern Pike counties, Kentucky, in order to determine the influence of the Stockton depositional ecosystem on those parameters. Vitrinite-rich Stockton lithotypes are dominated by Lycospora. Dull lithotypes, including both high- and low-ash yield durains, generally have abundant Densosporites, suggesting that the parent plant inhabited a fairly wide range of environments. Lithologies having tree ferns as an important component also have high fusinite + semifusinite and a low telinite/gelocollinite ratio. The aerial root bundles of the tree ferns were susceptible to oxidation and, for tissue not oxidized to inertinite, to preservation as gelocollinite. In the initial stages of formation, the Stockton mire was discontinuous and had a rather restricted floral assemblage. The presence of durains higher in the Stockton section, particularly the low-ash yield durains having petrographic indicators of degradation, suggests that portions of the mire developed as a domed peat. The termination of the mire as a high-sulfur, arboreous lycopod-domimated mire is consistent with the return to more planar mire development.

    St.-John's wort owes its name to the fact that it flowers at the time of the summer solstice on or around St. John's day on 24 June. Having been administered as a remedy by the Roman military doctor Proscurides as early as the 1st century AD, it was mainly used for magic potions during the Middle Ages. It was not only used to protect humans and animals against witches, demons and evil diseases, but it was also added to the fire when moulding "Freikugel" [1]. Paracelsus was one of the first doctors to concern themselves with St.-John's wort. However, where it had formerly been used for a plethora of indications, in more recent times it has found its place in the treatment of depression and anxiety disorders. In numerous clinical double-blind trials against placebo and other antidepressants the whole extract of St.-John's wort, e.g. as in Jarsin coated tablets, has proved to be just as effective as the other antidepressants for mild and moderate depression, but not for severe depression.

    Lionfish (Pterois spp.) are invasive species that have recently spread throughout the Caribbean. Lionfish are available for purchase in local markets for human consumption in several islands of the region. We examined the prevalence of ciguatoxins (CTXs) in lionfish from the French Antilles, a ciguatera-endemic region. The neuroblastoma-2a (N2a) cell assay was used to assess composite cytotoxicity in 120 fish samples collected from the surrounding waters of Guadeloupe (n = 60), Saint Barthélemy Islands (n = 55) and Saint Martin (n = 5). Twenty-seven of these samples exhibited CTX-like activity by the N2a assay. Ciguatoxin (CTX) was confirmed by liquid chromatography-tandem mass spectrometry (LC-MS/MS) in multiple samples that presented highest composite toxicity levels by N2a. Those fish found to contain CTXs were all from Saint Barthélemy. Lionfish from Guadeloupe and Saint Martin did not exhibit toxin activity, although the sample size from Saint Martin was insufficient to draw any conclusions as to the incidence of CTXs. In this study, we provide information about the potential hazard of ciguatera associated with the consumption of lionfish from known endemic areas. We also demonstrate the utility of the cell-based assay combined with LC-MS/MS to assess activity and to provide structural confirmation of CTXs respectively.

    The authors draw on ideas posited by Segal in her seminal paper 'A psychoanalytic approach to aesthetics' to explore idealization and the creative endeavour as it is imaginatively portrayed in the Poutney/Lazaridis production of Martinů's Julietta, performed by Opera North (2003). The opera is set in a dreamlike world in which confusion proliferates, and Julietta is portrayed as a modern-day siren, luring Mischa, the main character, on to the rocks of psychic withdrawal. It depicts an inner drama where music, narrative and spectacle work together to evoke the main character's struggle which touches on universal themes--the ongoing nature of infantile longings, the pain of loneliness and separation and the fear of madness. Through careful reading of the opera and consideration of Martinů's life, the authors reflect on the factors that may have shaped Martinů's relationship to this work, including his feelings towards his homeland, his mid-life crisis and the social and political turmoil of Europe at the time. The authors conclude by reflecting on the aesthetic experience of the opera and the way in which the music transforms the drama and seeks to extend our understanding of psychic truth.

    Fifteen trillion ft/sup 3/ of wet gas in place containing some 800 million bbl of associated liquids have been discovered in the San Martin and Cashiriari anticlines, which are located in the Subandean thrusted foldbelt of the Southern Ucayali basin of Peru. Ultimate recoverable volumes are estimated at 10 trillion ft/sup 3/ of gas and 500 million bbl of liquids including condensate (C5+) and LPG (C3/C4). Most of these potentially recoverable reserves are located in the Cashiriari structure (80% of the gas and 70% of the liquids). They were encountered in fair-excellent sandstone reservoirs of Early Permian and Late Cretaceous age and are thought to be derived from Carboniferous coaly shale source rocks. The Paleozoic (pre-Andean) sedimentary megacycle is represented by deeper shallow marine clastics of Ordovician to Early Carboniferous age (5000 m maximum), including Silurian glaciomarine deposits, overlain by up to 1200 m of Permian-Carboniferous platform carbonates and 600-1000( ) m of Lower Permian-lower Upper Permian coastal-continental clastics. The Mesozoic-Tertiary (Andean) megacycle is represented by a Campanian-Maastrichtian transgressive marine clastic/carbonate and overlying regressive clastic sequence (450 m maximum), followed by several thousand meters of Molasse-type continental infill of the Tertiary foredeep, which was created by the crustal loading in the wake of the compressional Andean orogeny (Peru, Inca, and Quechua phases). Late Tertiary folding and thrusting of the sub-Andean belt was superseded by regional Pleistocene uplift, and parts of the foreland continue to subside.

    External dosimetry needs at the four Martin Marietta Energy Systems facilities are served by Energy Systems Centralized External Dosimetry System (CEDS). The CEDS is a four plant program with four dosimeter distribution centers and two dosimeter processing centers. Each plant has its own distribution center, while processing centers are located at ORNL and the Y-12 Plant. The program has been granted accreditation by the Department of Energy Laboratory Accreditation Program (DOELAP). The CEDS is a TLD based system which is responsible for whole-body beta-gamma, neutron, and extremity monitoring. Beta-gamma monitoring is performed using the Harshaw/Solon Technologies model 8805 dosimeter. Effective October 1, 1992 the standard silver mylar has been replaced with an Avery mylar foil blackened on the underside with ink. This was done in an effort to reduce the number of light induced suspect readings. At this time we have little operational experience with the new blackened mylars-The CEDS neutron dosimeter is the Harshaw model 8806B. This card/holder configuration contains two TLD-600/TLD-700 chip pairs; one pair is located beneath a cadmium filter and one pair is located beneath a plastic filter. In routine personnel monitoring the CEDS neutron dosimeter is always paired with a CEDS beta-gamma dosimeter.The CEDS extremity dosimeter is composed of a Harshaw thin TLD-700 dosiclip placed inside a Teledyne RB-4 finger sachet. The finger sachet provides approximately 7 mg/cm[sup 2] filtration over the chip. A teflon ring surrounds the dosiclip to help prevent tearing of the vinyl sachet.

    The fame of its medical university and its reputation for field botany attracted visitors from all over Europe to seventeenth-century Montpellier. It was there that Martin Lister first made the acquaintance of John Ray in 1665. Twenty years later, in London, they cooperated in the production of the ambitious and lavishly illustrated Historia Piscium based on the notes of the late Francis Willughby. Ray, Lister and others contributed additional material. In their own work on fishes, cetaceans and shellfish Ray and Lister were considerably indebted to the Libri de piscibus marinis of an earlier Montpellier professor, Guillaume Rondelet, whose Aristotelian/Galenic approach to the study of medicine and living things was distinguished by a quite exceptional level of knowledge about aquatic species, based on a secure grasp of the classical and contemporary literature, but above all on his own observations in rivers, lakes, lagoons and the open sea, and his domestication (and dissection) of marine species in ponds and aquaria at his country house. Rondelet's book proved useful to Ray and to Lister as a work of reference, as a stimulus for reflection on biological problems, as an aid to nomenclature, as a source of precise descriptions of species, in both words and pictures, as a model to be improved upon in taxonomy, as a warning against reliance on hearsay, and as a valuable account of observations and experiments. Ray used it in much the same way as he used the work of those sixteenth-century botanists who met with his approval. Several of these had been Rondelet's pupils.

    Lutzomyia fraihai (Martins, Falcão & Silva 1979), described from Três Braços municipality (Bahia state, Brazil), is closely related to Nyssomyia yuilli yuilli (Young & Porter, 1972), described from Rio Anori, Antioquia, Colombia. The former species, despite the morphological differences reported by its authors, was included as a junior synonym of Ny. yuilli yuilli, and this status has been accepted by sand fly-taxonomists. However, we had an opportunity to examine both taxa, and a clear difference was noted in their male genitalia. In this study, the morphometric/morphologic characters of specimens that had been identified as Ny. yuilli yuilli from different localities (Brazil, Peru, Colombia, Bolivia) and type material of both Ny. yuilli yuilli and Lu. fraihai were analyzed. The results revealed that males from Brazil (Bahia, Acre, Pará, and Rondônia states) and Peru present statistically significant differences in the ratio between paramere rectangular and digitiform areas as well as for the cercus length and width of the aedeagal ducts tips, when compared with the type specimens of Ny. yuilli yuilli, but are statistically similar to those characters of Lu. fraihai However, females of the two species are indistinguishable. Thus, based on the male morphology, Ny. fraihai STAT REV N COM: was resurrected from the synonymy of Ny. yuilli yuilli. The specimens from the Atlantic forest biome and the Amazon biome in Brazil, Peru, and Bolivia in fact belong to Ny. fraihai This species presents a cis-Andean distribution, while Ny. yuilli yuilli has been found in both Andean and Trans-Andean areas.

    The Lesser Antilles subduction initiated in Lower Cretaceous at the eastern tip of the Caribbean plate where Atlantic is subducting westward bellow Caribbean plate. The associated island arc extends from St Martin (to the north) to Grenada Island (to the south). The northern half of the volcanic arc presents a peculiar morphology with (i) an eastern outer arc that was active from Eocene to Oligocene from St Martin to Martinique and (ii) a western inner one from Saba to Martinique which is active since the Miocene attesting for a westward jump of the volcanic arc at that time. The long-term deformation pattern and kinematics affecting the Lesser Antilles arcand its evolution from Eocene to Miocene, before its westward jump, remain poorly constrained. This study aims at constraining the deformation pattern expressed in the eastern outer arc of the Lesser Antilles during Eocene time, which is contemporaneous with arc formation. To achieve this goal, St Barthelemy Isand (St Barth) is a key target as it consists of Eocene volcanites inter layered with carbonate platform sequences, intruded by Oligocene dykes and pipes. During fieldwork, we accurately mapped the main tectonic features that affect the island, and characterized the mineralogy of the gouges and fluid circulation along the main faults. The kinematics data were used to perform inversions in order to recover the paleostate of stress and datable minerals found in fault gouge will be further used to constrain the timing of fault activity. We discuss the observed deformations within the regional tectonic framework and the birth of the Lesser Antilles volcanic arc. Firstly, we recover the Eocene local paleostress in St Barth corresponding to the first stages of island arc building. Secondly, we discuss the Eo-Oligocene evolution of the stress field at the island scale. Thirdly, thanks to the observed mineralogy we decipher the different deformation stages that occurred at distinct structural levels.

    In a series of papers, we have investigated the compatibility of the Kimber-Martin-Ryskin (KMR) and Martin-Ryskin-Watt (MRW) unintegrated parton distribution functions (UPDFs) as well as the description of the experimental data on the proton structure functions. The present work is a sequel to that survey, via calculation of the transverse-momentum distribution of the electroweak gauge vector bosons in the kt-factorization scheme, by the means of the KMR, the leading-order (LO) MRW, and the next-to-leading-order (NLO) MRW UPDF, in the NLO. To this end, we have calculated and aggregated the invariant amplitudes of the corresponding involved diagrams in the NLO and counted the individual contributions in different frameworks. The preparation process for the UPDF utilizes the parton distribution functions of Martin et al., MSTW2008-LO, MSTW2008-NLO, MMHT2014-LO, and MMHT2014-NLO, as the inputs. Afterward, the results have been analyzed against each other as well as the existing experimental data, i.e., D0, CDF, ATLAS, and CMS collaborations. Our calculations show excellent agreement with the experiment data. It is, however, interesting to point out that the calculation using the KMR framework illustrates a stronger agreement with the experimental data, despite the fact that the LO MRW and the NLO MRW formalisms employ a better theoretical description of the Dokshitzer-Gribov-Lipatov-Altarelli-Parisi evolution equation. This is of course due to the use of the different implementation of the angular ordering constraint in the KMR approach, which automatically includes the resummation of ln (1 /x ) , Balitski-Fadin-Kuraev-Lipatov logarithms, in the LO Dokshitzer-Gribov-Lipatov-Altarelli-Parisi evolution equation.

    The prediction of future space travel in the next millennium starts by examining the past and extrapolating into the far future. Goals for the 21st century include expanded space travel and establishment of permanent manned outposts, and representation of Lunar and Mars outposts as the most immediate future in space. Nuclear stage design/program considerations; launch considerations for manned Mars missions; and far future propulsion schemes are outlined.

  1. The Wake of St. Vincent.

    1997-03-01

    The island of St. Vincent and the other Windward Islands in the southeastern Caribbean were chosen as a field site for the study of weak mountain wakes. By the authors' definition, a `weak wake' forms when the potential vorticity generated by a mountain is not strong enough to advect itself into eddies; rather, it is simply advected downstream by the ambient flow. GOES-8 and Landsat sunglint images unambiguously revealed that the mountainous Windward Islands have remarkably long straight wakes. The length of St. Vincent's wake exceeds 300 km although its width is only 20 km. Near the islands, the wake structures reflect the details of the island topography. These wakes do not exhibit any obvious diurnal effect.Boat surveys in the lee of St. Vincent confirmed the existence of features seen in the images: the sharp wake boundary, the small valley-induced jet embedded in the near wake, and the absence of any reverse flow. Aircraft surveys gave evidence of descent over the island and showed that the wake air is relatively warm and dry. The length of the wake (L) agrees with the formula L = H/2CD (where H is the wake depth and CD is the surface drag coefficient), implying that the reacceleration of the wake air is caused by the ambient streamwise pressure gradient rather than by lateral entrainment of momentum or geostrophic adjustment.Two numerical models were used to simulate St. Vincent's wake, a single-layer hydrostatic model and a 3D nonhydrostatic model. Both models indicated that air descent, acceleration, wave breaking, and weak potential vorticity generation occur over the island, causing a long straight wake.

    Commercially manufactured New York City (NYC) medium and modified Thayer-Martin (MTM) medium were compared for their ability to isolate Neisseria gonorrhoeae from clinical specimens. Twenty-seven public health laboratories throughout California evaluated 4,802 specimens collected from patients attending either sexually transmitted disease or family planning clinics. Total of 726 and 737 N. gonorrhoeae isolates were recovered from NYC and MTM medium, respectively. Although less contamination was noted on NYC medium, MTM medium was equivalent to commercially prepared NYC medium for the isolation of N. gonorrhoeae from clinical specimens.

    1981-01-01

    This report provides water users with detailed information on the location, quantity, and quality of water available from underground coal mines in the Breathitt Formation of Pennsylvanian age in part of eastern Kentucky. The principal coal seams mined are the Van Lear in Johnson County and the Alma in Martin County. Coal mines that contained water were located by field inventory and coal-mine maps. The principal factors that affect the occurrence of water in coal mines are the size of the recharge area overlying the mine, the intensity and duration of precipitation, and the altitude of the mine relative to that of the nearest perennial stream. Ten above-drainage mines (that is, mines at higher elevations than that of the nearest perennial stream) are considered potential sources of water. Discharge from these mines ranged from 12 to 1,700 gallons per minute. The highest sustained discharge from a mine ranged from 750 to 1,200 gallons per minute. The water in coal mines is part of the hydrologic system and varies seasonally with precipitation. Annual discharge from most above-drainage mines ranged from 3 to 10 percent of annual precipitation on the 1and-surface area above the mine. Eight below-drainage mines are considered potential sources of water. Two were test-pumped at rates of 560 to 620 gallons per minute for as long as 6 hours. After test pumping the Warfield Mining No. 1 mine during September 1977 and March 1978, the recovery (or recharge) rates were significantly different. In September, the recharge rate was about 1,150 gallons per minute, but in March the recharge rate was 103,500 gallons per minute. This difference reflects the seasonal variations in the amount of water available to the ground-water system. Estimates of water stored in below-drainage mines ranged from 22 to 1,462 million gallons. This storage represents a safety factor sufficient to provide water through periods of limited recharge to the mine. Most mine water is of the calcium

    George Martin Baer, known for his development of the oral rabies vaccine instrumental in rabies control in Europe, died on 2 June 2009 at the age of 73 in Mexico City, Mexico. He was born on 12 January 1936 in London, England, to German immigrants who had fled Nazi Germany. His family emigrated to the United States in 1940 where he grew up in New Rochelle, New York. George had a love of animals, particularly horses, which may have influenced his career path. He earned an undergraduate degree in agricultural sciences in 1954 from Cornell University followed by a degree in veterinary medicine in 1959. He then went on to earn a master's degree in public health in 1960 from the University of Michigan. During some time in Mexico, George met and fell in love with his wife, Maria Olga Lara. Thanks to James H. Steele, his long-time friend and mentor, he started his public health career with the Centers for Disease Control (CDC) and was assigned to the New York State Health Department where he learned epidemiology and virology. He went on to work on bat rabies at the CDC's Southwest Rabies Investigations Laboratory in New Mexico. From 1966 to 1969, he worked with the National Institute for Livestock Research (Instituto Nacional de Investigaciones Pecuarias: INIP) in Mexico and helped develop the Plan Derriengue to control paralytic bovine rabies which became the early work in the development of Mexico's rabies control programmes. He returned to Atlanta in 1969 to direct the CDC Rabies Laboratory. There, he led a team of researchers in developing an oral rabies vaccine for wildlife, earning him the title 'The Father of Oral Rabies Vaccination'. His text, The Natural History of Rabies, first published in 1975 and again in 1991, continues to be a definitive international reference for rabies control. After his retirement, George returned to Mexico and continued his research and training, working to develop not only public health programmes, but new researchers as well. At the

    1981-01-01

    The need for a method for estimating flow characteristics of flood hydrographs between Portland, Colo., and John Martin Reservoir has been promoted with the construction of the Pueble Reservoir. To meet this need a procedure was developed for predicting floodflow peaks, traveltimes, and volumes at any point along the Arkansas River between Portland and John Martin Reservoir without considering the existing Pueble Reservoir detention effects. A streamflow-routing model was calibrated initially and then typical flood simulations were made for the 164.8-mile study reach. Simulations were completed for varying magnitudes of floods and antecedent streamflow conditions. Multiple regression techniques were then used with simulation results as input to provide predictive relationships for food peak, volume, and traveltime. Management practices that may be used to benefit water users in the area include providing methods for the distribution and allotment of the flood waters upstream of Portland to different downstream water users according to Colorado water law and also under the Arkansas River Compact.

Once acute coronary syndrome is ruled out by emergent cardiac catheterization alternative diagnosis should be sorted. Abdominal pathologies, like acute pancreatitis and acute cholecystitis, can present with ST elevation in the inferior leads.

    2009-06-01

    This article aims to summarize the current state of knowledge on St. John's wort (Hypericum perforatum L.) which is one of the oldest and best investigated medicinal herbs. Dried alcoholic extracts are the most important preparations on the market although a variety of other preparations are available. Depressive disorders according to modern diagnostic standards are the best known and most widely investigated indication although the more traditional, broader indication of 'psycho-vegetative disorders, depressive disorders, anxiety and/or nervous agitation', including diagnoses such as somatoform disorders, might more adequately describe what Hypericum extracts are actually used for by many practitioners. The exact mechanisms of action are still unclear, but the available research clearly shows that various bioactive constituents contribute to the clinical effects reported, often in a synergistic manner. Hypericum extracts have consistently shown activity in pharmacological models related to antidepressant effects. Randomized clinical trials show that Hypericum extracts are more effective than placebo and similarly effective as standard antidepressants while having better tolerability in the acute treatment of major depressive episodes. The most important risk associated with Hypericum extracts are interactions with other drugs. Therefore, physicians need to be informed whether their patients take St. John's wort products. If the risk of interactions is adequately taken into account, high quality Hypericum extracts are an effective and safe tool in the hand of qualified health profession-als in primary care.

    Clark, Barbara J

    2016-01-01

    Adrenocorticotropin hormone (ACTH) produced by the anterior pituitary stimulates glucocorticoid synthesis by the adrenal cortex. The first step in glucocorticoid synthesis is the delivery of cholesterol to the mitochondrial matrix where the first enzymatic reaction in the steroid hormone biosynthetic pathway occurs. A key response of adrenal cells to ACTH is activation of the cAMP-protein kinase A (PKA) signaling pathway. PKA activation results in an acute increase in expression and function of the Steroidogenic Acute Regulatory protein (StAR). StAR plays an essential role in steroidogenesis- it controls the hormone-dependent movement of cholesterol across the mitochondrial membranes. Currently StAR's mechanism of action remains a major unanswered question in the field. However, some insight may be gained from understanding the mechanism(s) controlling the PKA-dependent phosphorylation of StAR at S194/195 (mouse/human StAR), a modification that is required for function. This mini-review provides a background on StAR's biology with a focus on StAR phosphorylation. The model for StAR translation and phosphorylation at the outer mitochondrial membrane, the location for StAR function, is presented to highlight a unifying theme emerging from diverse studies.

    In their article on gender development, C. L. Martin, D. N. Ruble, and J. Szkrybalo (see record 2002-18663-003) contrasted their conception of gender development with that of social cognitive theory. The authors of this commentary correct misrepresentations of social cognitive theory and analyze the conceptual and empirical status of Martin et al.'s (2002) theory that gender stereotype matching is the main motivating force of gender development. Martin et al. (2002) based their claim for the causal primacy of gender self-categorization on construal of gender discrimination as rudimentary self-identity, equivocal empirical evidence, and dismissal of discordant evidence because of methodological deficiencies. The repeated finding that gendered preferences and behavior precede emergence of a sense of self is discordant with their theory. Different lines of evidence confirm that gender development and functioning are socially situated, richly contextualized, and conditionally manifested rather than governed mainly by an intrinsic drive to match stereotypic gender self-conception.

    Cold-induced sweetening (CIS) in potato is detrimental to the quality of processed products. Conversion of starch to reducing sugars (RS) by amylases is considered one of the main pathways in CIS but is not well studied. The amylase genes StAmy23, StBAM1, and StBAM9 were studied for their functions in potato CIS. StAmy23 is localized in the cytoplasm, whereas StBAM1 and StBAM9 are targeted to the plastid stroma and starch granules, respectively. Genetic transformation of these amylases in potatoes by RNA interference showed that β-amylase activity could be decreased in cold-stored tubers by silencing of StBAM1 and collective silencing of StBAM1 and StBAM9. However, StBAM9 silencing did not decrease β-amylase activity. Silencing StBAM1 and StBAM9 caused starch accumulation and lower RS, which was more evident in simultaneously silenced lines, suggesting functional redundancy. Soluble starch content increased in RNAi-StBAM1 lines but decreased in RNAi-StBAM9 lines, suggesting that StBAM1 may regulate CIS by hydrolysing soluble starch and StBAM9 by directly acting on starch granules. Moreover, StBAM9 interacted with StBAM1 on the starch granules. StAmy23 silencing resulted in higher phytoglycogen and lower RS accumulation in cold-stored tubers, implying that StAmy23 regulates CIS by degrading cytosolic phytoglycogen. Our findings suggest that StAmy23, StBAM1, and StBAM9 function in potato CIS with varying levels of impact.

The Idaho studies showed that, although the ashfall altered the food chains of some forest streams, within a year they fully recovered. The effects of ashfall on lake benthic organisms are still being assessed by sediment sampling. The Montana studies reported on snow avalanche models adapted to mudflows, trophic impact of ash deposits on Montana lakes, and the volcanic ash as nutrient subsidy to sub-alpine lakes. The Oregon studies reported herring and smelt egg and larvae damage due to suspended ash. The drainage patterns in eruption debris were studied along with the filling of Columbia River berths with ash.

    As the first chief of an independent neurosurgical unit founded in Belgium in 1948, Paul Martin is to be regarded as the promoter of this specialty in Belgium. After graduation from the ULB. medical school, he was one of the first Belgian doctors to stay for two years (1920-22) in United States in the surgical departments of Halsted and Cushing. He returned to the Peter Bent Brigham Hospital in 1929 for one year as chief of the laboratory of experimental surgery. His career will be impressed by the development of various techniques to localize an intracranial mass such as the ventriculography, encephalography, electroencephalography and later angiography, myelography and iodoventriculography. The introduction of the electrocoagulation was also one of the major advances in surgical technique during his lifetime. In 1955, he was one of the founders of "Neurochirurgie", the official journal of the "Société de neurochirurgie de langue française".

The phenomenological interview guided the meeting with seven caregivers of children with AIDS, selected in a teaching hospital of Porto Alegre-RS, southern of Brazil. The data were interpreted in the light of hermeneutics, emerging the unit of meaning Dialogues 'between' the familiar I and the Eternal THOU. The dialogues take place in the search for answers that allow the understanding of the significance of the impact and challenges they face while living with AIDS. As well, they reveal hope in changes, in the cure and in a vaccine development. We believe that knowing the importance of dialogue in the context of HIV/AIDS epidemic provide the development of a nursing care that brings together the technical-scientific and humanistic aspects.

    The geochemistry, petrology, and palynology of the Duckmantian-age Pond Creek coal bed were investigated in northern Pike and southern Martin counties, eastern Kentucky. The coal bed exhibits significant vertical variation in the investigated geochemical parameters, with many diagenetic overprints of the original geochemistry. Included in the range of geochemical signatures are the presence of elements, particularly TiO2 and Zr, suggesting the detrital influences at the time of deposition of a low-vitrinite durain; a high CaO zone with elevated B/Be, both suggesting marine influence, in a lithotype in the middle of the coal bed; and the postdepositional emplacement of pyrite in the uppermost lithotype. Individual lithotypes, each representing distinct depositional environments, all complicated to some degree by diagentic overprints, comprise the complex history of the coal bed. ?? 2004 Elsevier B.V.

    Background The safety net system remains an important part of the health care system for uninsured and minority populations, however, the closure of safety net hospitals changes the availability of care. Using community-based participatory research methods, we explored the impact of hospital closure among late middle aged and elderly racial/ethnic minorities in South Los Angeles. Methods Telephone survey of participants in both 2008, after hospital closure, and 2003, before hospital closure, who self-identified as African American or Latino, were over the age of 50 and lived in zip codes of South Los Angeles. We developed multiple logistic regression models on imputed data sets weighted for non-response and adjusted for self-reported measures of demographic and clinical characteristics to examine the odds of reporting delays in care. Results After adjusting for covariates known to influence access to care and distributed differently in the two survey samples, we found significantly greater delays in care. Following the closure of the Martin Luther King, Jr. safety net hospital, the adjusted odds ratios were 1.70 (95% CI 1.01, 2.87) for delays in care, 1.88 (95% CI 1.06, 3.13) for problems receiving needed medical care, and 2.62 (95% CI 1.46, 4.67) for seeing a specialist. Conclusions Our survey of older minority adults in South Los Angeles found increased delays in access to care for needed medical services after the closure of Martin Luther King, Jr. Hospital. As health care reform unfolds, monitoring for changes in access to care that may result from new policies will be important to address future disparities, particularly for vulnerable populations.

    Directional selection for parasite resistance is often intense in highly social host species. Using a partial cross-fostering experiment we studied environmental and genetic variation in immune response and morphology in a highly colonial bird species, the house martin (Delichon urbica). We manipulated intensity of infestation of house martin nests by the haematophagous parasitic house martin bug Oeciacus hirundinis either by spraying nests with a weak pesticide or by inoculating them with 50 bugs. Parasitism significantly affected tarsus length, T cell response, immunoglobulin and leucocyte concentrations. We found evidence of strong environmental effects on nestling body mass, body condition, wing length and tarsus length, and evidence of significant additive genetic variance for wing length and haematocrit. We found significant environmental variance, but no significant additive genetic variance in immune response parameters such as T cell response to the antigenic phytohemagglutinin, immunoglobulins, and relative and absolute numbers of leucocytes. Environmental variances were generally greater than additive genetic variances, and the low heritabilities of phenotypic traits were mainly a consequence of large environmental variances and small additive genetic variances. Hence, highly social bird species such as the house martin, which are subject to intense selection by parasites, have a limited scope for immediate microevolutionary response to selection because of low heritabilities, but also a limited scope for long-term response to selection because evolvability as indicated by small additive genetic coefficients of variation is weak.

    The St genome is one of the most fundamental genomes in Triticeae. Repetitive sequences are widely used to distinguish different genomes or species. The primary objectives of this study were to (i) screen a new sequence that could easily distinguish the chromosome of the St genome from those of other genomes by fluorescence in situ hybridization (FISH) and (ii) investigate the genome constitution of some species that remain uncertain and controversial. We used degenerated oligonucleotide primer PCR (Dop-PCR), Dot-blot, and FISH to screen for a new marker of the St genome and to test the efficiency of this marker in the detection of the St chromosome at different ploidy levels. Signals produced by a new FISH marker (denoted St2-80) were present on the entire arm of chromosomes of the St genome, except in the centromeric region. On the contrary, St2-80 signals were present in the terminal region of chromosomes of the E, H, P, and Y genomes. No signal was detected in the A and B genomes, and only weak signals were detected in the terminal region of chromosomes of the D genome. St2-80 signals were obvious and stable in chromosomes of different genomes, whether diploid or polyploid. Therefore, St2-80 is a potential and useful FISH marker that can be used to distinguish the St genome from those of other genomes in Triticeae.

    ST Microelectronics microcontrollers and processors are readily available, capable and economical processors. Unfortunately they lack a broad user base like similar offerings from Texas Instrument, Atmel, or Microchip. All of these devices could be useful in economical devices for remote sensing applications used with environmental sensing. With the increased need for environmental studies, and limited budgets, flexibility in hardware is very important. To that end, and in an effort to increase open support of ST devices, I am sharing my teams' experience in interfacing a common environmental sensor communication protocol (SDI-12) with ST devices.

    ST13, a cytoplasmic homotetramer protein belonging to the FAM10 family, interacts with HSC70 as well as DNAJ homologs and HSP90. ST13 is an adaptor protein that mediates the association of the heat shock proteins HSP70 and HSP90. It has been shown to be involved in the assembly process of glucocorticoid receptor, which requires the assistance of multiple molecular chaperones. The expression of the ST13 gene is reported to be downregulated in colorectal carcinoma tissue suggesting that is a candidate tumor suppressor gene.

    In China, Klebsiella pneumoniae carbapenemase (KPC) -producing K. pneumoniae isolates have been identified. However, little is known about the spread and outbreak of KPC-producing enterobacterial pathogens. In this study, 48 non-duplicated KPC-producing isolates were analysed for genetic relatedness by pulsed-field gel electrophoresis (PFGE), antimicrobial susceptibility by E-test, and sequence type (ST) by multilocus sequence typing. S1-PFGE and Southern blot were used for plasmid profiling, and PCR and subsequent sequencing were performed to determine the effects of genetic background on the blaKPC gene. From December 2011 to June 2012, an outbreak of the KPC-2-producing K. pneumoniae was observed. The 48 isolates of K. pneumoniae are categorized into eight PFGE types (A1, A2, A3, A4, B, C, D and E). The predominant pathogens of the outbreak were strains with PFGE types A1, A2 and A3, which all belong to ST11. Furthermore, ST37, ST392 and ST395 KPC-2-producing K. pneumoniae isolates have also been sporadically identified. The blaKPC-2 -carrying plasmids vary in size from 30 to 220 kb. The genetic environments of the blaKPC-2 gene for most strains were consistent with the genetic structure of blaKPC-2 on the plasmid pKP048. In conclusion, the dissemination and outbreak of KPC-2-producing K. pneumoniae isolates in this study appeared to be clonal, and ST11 K. pneumoniae was the predominant clone attributed to the outbreak. This is the first study to report the emergence and spread of KPC-producing K. pneumoniae ST392 and ST395 worldwide. Our findings suggest that horizontal transfer of Tn3-based transposons might mediate the spread of blaKPC-2 gene between different K. pneumoniae clones in China.

    2013-01-01

    Jean-Martin Charcot (1825-1893), the "father of neurology" in France and much beyond, was also the man who established academic psychiatry in Paris, differentiating it from clinical alienism. In his teaching, he used artistic representations from previous centuries to illustrate the historical developments of hysteria, mainly with the help of his pupil Paul Richer. Charcot liked to draw portraits (in particular, sketches of colleagues during boring faculty meetings and students' examinations), caricatures of himself and others, church sculptures, landscapes, soldiers, etc. He also used this skill in his clinical and scientific work; he drew histological or anatomic specimens, as well as patients' features and demeanor. His most daring artistic experiments were drawing under the influence of hashish. Charcot's tastes in art were conservative; he displayed no affinity for the avant-gardes of his time, including impressionism, or for contemporary musicians, such as César Franck or Hector Berlioz. Léon Daudet, son of Charcot's former friend and famous writer Alphonse Daudet, described Charcot's home as a pseudo-gothic kitsch accumulation of heteroclite pieces of furniture and materials. However, as Henry Meige wrote a few years after his mentor's death, Charcot the artist remains "inseparable from Charcot the physician."

    2001-07-01

    The Martin Buber-C.G. Jung disputations rather than the Freud-Jung split or Samuels's post-Jungian categories is considered the more significant paradigm for understanding the conflicts erupting within the Jungian community surrounding clinical practice and candidate training. Looking through the lens of the Freud-Jung split keeps the conflicts focused on the theoretical and technical differences concerning such concepts as object-relations, transference-countertransference, neutrality, clinical boundaries. The Buber-Jung disputations move the discussion into a different and more foundational arena, namely the vertical and horizontal psychological considerations of the experience of the Sacred and how that dimension is supported or thwarted in clinical practice and candidate training by the respective allegiances of the 'warriors' in the 'Holy Wars'. Experiencing the texture of the Buber-Jung disputations as well as grappling with their content suggests that a more dialogical approach to actual clinical material may be a more fruitful way to understand the work of analysis and the business of candidate training.

    The diet of the House Martin Delichon urbica was analyzed in a suburban area in Pins maritimes, northeast of Algiers (Algeria). The diet was determined by analyzing 120 faecal samples collected from a breeding colony between April and September 2007. Insects were the most numerous prey types (99.86%). Hymenopterans were the dominant preys (56.99%), followed by Coleopterans (20.14%), Homopterans (14.22%), Heteropterans (5.45%), and Dipterans (3.10%). Division of the prey items into families demonstrated that the highest relative frequency was large Hymenopterans in the family Formicidae (54.0%). The dominant species in the diet was Tetramorium biskrensis, which comprised 32.6% of the diet. It was followed by Camponotus barbaricus (6.9%) and Monomorium salomonis (5.6%). Comparison between diet and availability of preys using the Savage index showed that T. biskrensis, Crematogaster scutelaris, Pheidole pallidula, Diptera sp. unident. and Aphidae sp. unident. were positively selected by D. urbica.

    An asaccharolytic, gram-negative, oxidase-positive diplococcus was isolated on Martin-Lewis medium from the cervix of a patient attending an arthritis clinic at Seattle Public Health Hospital, Seattle, Wash. This strain, NRL 32165, did not produce detectable acid from glucose, maltose, sucrose, fructose, mannitol, or lactose in either cystine Trypticase agar (BBL Microbiology Systems, Cockeysville, Md.) or modified oxidation-fermentation medium and was identified presumptively as a glucose-negative Neisseria gonorrhoeae strain, but was identified later as Neisseria cinerea on the basis of its biochemical reactions. Nitrate was not reduced, nitrite (0.001%, wt/vol) was reduced, and polysaccharide was not produced from sucrose. Proline, arginine, and cystine-cysteine were required for growth on defined medium. Strain NRL 32165 did not react with antigonococcal protein I monoclonal antibodies and did not produce immunoglobulin A protease. In DNA:DNA homology studies with N. gonorrhoeae NRL 8038 (F62) and N. cinerea type strain NRL 30003, strain NRL 32165 showed 95% homology relative to N. cinerea and 44% homology relative to N. gonorrhoeae. Thus, the identity of strain NRL 32165 was confirmed as N. cinerea (von Lingelsheim 1906) Murray 1939. Of all Neisseria spp., N. cinerea is most likely to be misidentified as a glucose-negative N. gonorrhoeae strain.

    1993-10-01

    The US Department of Energy (DOE) currently owns and operates a marine terminal on the west bank of the Mississippi River at St. James, Louisiana. The St. James facility was constructed by the Department to provide marine services associated with the fill and drawdown of the Strategic Petroleum Reserve (SPR) crude oil storage facilities located at Bayou Choctaw and Weeks Island, Louisiana. Although strategic to the mission of the SPR in the event of a national emergency, the St. James terminal is situated such that it has a high potential to also serve the commercial industry`s needs for crude oil terminalling and storage. The St. James terminal is located approximately 45 miles west of New Orleans and 30 miles southeast of Baton Rouge, and approximately 160 miles upstream from the mouth of the Mississippi River. Construction of the St. James terminal was initiated in 1978 and was completed in 1980. Since then, the terminal has received and transferred over 125 million barrels of crude oil to the SPR sites for storage. For crude oil distribution, the St. James terminal was connected to the neighboring LOCAP terminal by a 0.1 mile 36-inch pipeline in 1981 and to the Capline terminal by a 0.5 mile 30-inch pipeline in 1988. The terminal also has a 30-inch pipeline connection to the Koch oil terminal which was used for initial fill purposes; however, this pipeline has been disconnected and is currently inactive. A complete description of the St. James terminal facilities, operational capabilities, operational certifications, and future Government requirements are presented in Sections 2, 3, 4, and 5 respectively.

    2014-01-01

    Background The supplementary grading system for brain arteriovenous malformations (AVM) was introduced in 2010 as a tool for improving preoperative risk prediction and selecting surgical patients. Objective To demonstrate, in this multicenter validation study, that supplemented Spetzler-Martin grades have greater predictive accuracy than Spetzler-Martin grades alone. Methods Data collected from 1009 AVM patients who underwent AVM resection were used to compare predictive powers of Spetzler-Martin grades (SM) and supplemented Spetzler-Martin grades (SM-Supp). Patients included the original 300 UCSF patients plus those treated thereafter (N=117), and an additional 592 patients from three other centers. Results In the combined cohort, the SM-Supp system performed better than SM system alone: AUROC=0.75 (95% CI: 0.71 - 0.78) for SM-Supp and AUROC=0.69 (95% CI: 0.65 - 0.73) for SM (p < 0.001). Stratified analysis fitting models within three different follow-up groupings (< 6 months, 6 months – 2 years, and > 2 years) demonstrated that the SM-Supp system performed better than SM system for both medium (AUROC=0.71 vs. 0.62, p=0.003) and long follow-up (AUROC=0.69 vs. 0.58, p=0.001). Patients with SM-Supp grades ≤ 6 had acceptably low surgical risks (0 – 24%), with a significant increase in risk for grades above 6 (39% – 63%). Conclusion This study validates the predictive accuracy of the supplementary grading system in a multicenter cohort. SM-Supp grade of 6 is a cut-off or boundary for AVM operability. Supplemented grading is currently the best method of estimating neurological outcomes after AVM surgery, and we recommend it as a starting point in the evaluation of AVM operability. PMID:25251197

  3. Stückelberg formulation of holography

    NASA Astrophysics Data System (ADS)

    Dvali, Gia; Gomez, Cesar; Wintergerst, Nico

    2016-10-01

    We suggest that holography can be formulated in terms of the information capacity of the Stückelberg degrees of freedom that maintain gauge invariance of the theory in the presence of an information boundary. These Stückelbergs act as qubits that account for a certain fraction of quantum information. Their information capacity is measured by the ratio of the inverse Stückelberg energy gap to the size of the system. Systems with the smallest gap are maximally holographic. For massless gauge systems this information measure is universally equal to the inverse coupling evaluated at the systems' length scale. In this language it becomes very transparent why the Stückelberg information capacity of black holes saturates the Bekenstein bound and accounts for the entire information of the system. The physical reason is that the strength of quantum interaction is bounded from below by the gravitational coupling, which scales as area. Observing the striking similarity between the scalings of the energy gap of the boundary Stückelberg modes and the Bogoliubov modes of critical many-body systems, we establish a connection between holography and quantum criticality through the correspondence between these modes.

    This is a spaceborne radar image of the area surrounding St. Louis, Missouri, where the Mississippi and Missouri Rivers come together. The city of St. Louis is the bright gold area within a bend in the Mississippi River at the lower center of the image. The rivers show up as dark blue sinuous lines. Urbanized areas appear bright gold and forested areas are shown as a brownish color. Several bridges can be seen spanning the river near downtown St. Louis. The Missouri River flows east, from left to right, across the center of the image, and meets the Mississippi River, which flows from top to bottom of the image. A small stretch of the Illinois River is shown at the top of the image where it merges with the Mississippi. The Mississippi forms the state boundary between Illinois (to the right) and Missouri (to the left). Flat farmland areas within the river floodplains appear blue on the image.

  5. MARTINS: A foam/film flow model for molten material relocation in HWRs with U-Al-fueled multi-tube assemblies

    Some special purpose heavy-water reactors (EM) are made of assemblies consisting of a number of coaxial aluminum-clad U-Al alloy fuel tubes and an outer Al sleeve surrounding the fuel tubes. The heavy water coolant flows in the annular gaps between the circular tubes. Analysis of severe accidents in such reactors requires a model for predicting the behavior of the fuel tubes as they melt and disrupt. This paper describes a detailed, mechanistic model for fuel tube heatup, melting, freezing, and molten material relocation, called MARTINS (Melting and Relocation of Tubes in Nuclear subassembly). The paper presents the modeling of the phenomena in MARTINS, and an application of the model to analysis of a reactivity insertion accident. Some models are being developed to compute gradual downward relocation of molten material at decay-heat power levels via candling along intact tubes, neglecting coolant vapor hydrodynamic forces on molten material. These models are inadequate for high power accident sequences involving significant hydrodynamic forces. These forces are included in MARTINS.

    Calcium-dependent protein kinases, CDPKs, decode calcium (Ca2+) transients and initiate downstream responses in plants. In order to understand how CDPKs affect plant physiology, their specific target proteins must be identified. In tobacco, the bZIP transcription factor Repression of Shoot Growth (NtRSG) that modulates gibberellin (GA) content is a specific target of NtCDPK1. StCDPK3 from potato is homologous (88% identical) to NtCDPK1 even in its N-terminal variable domain. In this work, we observe that NtRSG is also phosphorylated by StCDPK3. The potato RSG family of transcription factors is composed of three members that share similar features. The closest homologue to NtRSG, which was named StRSG1, was amplified and sequenced. qRT-PCR data indicate that StRSG1 is mainly expressed in petioles, stems, lateral buds, and roots. In addition, GA treatment affected StRSG1 expression. StCDPK3 transcripts were detected in leaves, petioles, stolons, roots, and dormant tubers, and transcript levels were modified in response to GA. The recombinant StRSG1-GST protein was produced and tested as a substrate for StCDPK3 and StCDPK1. 6xHisStCDPK3 was able to phosphorylate the potato StRSG1 in a Ca2+-dependent way, while 6xHisStCDPK1 could not. StCDPK3 also interacts and phosphorylates the transcription factor StABF1 (ABRE binding factor 1) involved in ABA signaling, as shown by EMSA and phosphorylation assays. StABF1 transcripts were mainly detected in roots, stems, and stolons. Our data suggest that StCDPK3 could be involved in the cross-talk between ABA and GA signaling at the onset of tuber development.

    Columbia Gas and the United States Department of Energy (DOE) have successfully completed field work on a horizontally drilled Devonian shale well located in Martin County, Kentucky. The objective of this cofunded project is to assess the effectiveness and economic feasibility of applying horizontal drilling and hydraulically fracturing stimulation techniques to enhance the extraction of natural gas from the Devonian shale. The well is comprised of three segments: a conventional vertical section, an angle build section and a horizontal section. The well reached a measured depth (MD) of 6263 feet, 3810 feet true vertical depth (TVD), with a horizontal displacement of 2812 feet achieved in the desired direction of N10{degrees}W. Both air and foam were used as drilling fluids. The vertical, lateral and tangent sections were drilled using conventional rotary drilling methods. Downhole motors were used to build angle. A total combined final open flow of 3.1 MMcfd was measured from all zones. Total well expenditures are approximately $1,460,000. Of this amount, $700,000 is directly related to the research and learning curve experience aspects. It is projected that the same horizontal well could be drilled with existing technology for $700,000. If advanced can be made in MWD systems for air drilling environments, wells of this type could be drilled routinely for $500,000. It appears that application of horizontal drilling will result in at least acceleration of gas production and possibly the addition of recoverable reserves from the Devonian shale. Production data, necessary to validate this statement, are also required to determine the economics. As we gain experience and technology advances, cost reductions will occur; this will result in economic improvement.

    Climate change has recently been implicated in poleward shifts of many tropical species including corals; thus attention focused on higher-latitude coral communities is warranted to investigate possible range expansions and ecosystem shifts due to global warming. As the northern extension of the Florida Reef Tract (FRT), the third-largest barrier reef ecosystem in the world, southeast Florida (25–27° N latitude) is a prime region to study such effects. Most of the shallow-water FRT benthic habitats have been mapped, however minimal data and limited knowledge exist about the coral reef communities of its northernmost reaches off Martin County. First benthic habitat mapping was conducted using newly acquired high resolution LIDAR bathymetry and aerial photography where possible to map the spatial extent of coral reef habitats. Quantitative data were collected to characterize benthic cover and stony coral demographics and a comprehensive accuracy assessment was performed. The data were then analyzed in a habitat biogeography context to determine if a new coral reef ecosystem region designation was warranted. Of the 374 km2 seafloor mapped, 95.2% was Sand, 4.1% was Coral Reef and Colonized Pavement, and 0.7% was Other Delineations. Map accuracy assessment yielded an overall accuracy of 94.9% once adjusted for known map marginal proportions. Cluster analysis of cross-shelf habitat type and widths indicated that the benthic habitats were different than those further south and warranted designation of a new coral reef ecosystem region. Unlike the FRT further south, coral communities were dominated by cold-water tolerant species and LIDAR morphology indicated no evidence of historic reef growth during warmer climates. Present-day hydrographic conditions may be inhibiting poleward expansion of coral communities along Florida.

    The recent appearance of methicillin-resistant Staphylococcus pseudintermedius (MRSP) is a concern for both veterinary and human healthcare. MRSP clonal lineages with sequence type (ST) 71-spa t02-staphylococcal cassette chromosome mec (SCCmec) II-III and ST68-spa t06-SCCmec V have spread throughout Europe and North America, respectively. The current study compared the molecular characteristics of 43 MRSP isolates from dogs in Japan with those of MRSP from previous reports using multilocus sequence typing based on seven housekeeping genes, SCCmec typing, and detection of antimicrobial resistance genes. Three related clonal lineages, ST71, ST169, and the newly registered ST354, were observed in SCCmec II-III isolates from Japan, despite MRSP SCCmec II-III isolates being thought to belong to a single clonal lineage. The majority of SCCmec II-III isolates belonging to ST169 (9/11) and ST354 (3/3), but not ST71 (0/11), harboured tetM. Four STs were observed for the SCCmec V isolates; however, neither ST68 nor related STs were found in the Japanese MRSP isolates. In conclusion, MRSP SCCmec II-III isolates from Japan belonged to ST71 and related STs (ST169 and ST354). A variety of MRSP SCCmec V clones, including some novel clones, were identified.

    The prevalence of antimicrobial resistant Escherichia coli was tested in symbovine flies and sympatric house martins (Delichon urbica) at a dairy farm. Antimicrobial resistant E. coli was detected in 89% (n=147) of isolates from flies within a calf barn. Isolates with the same antimicrobial resistance phenotypes, genes, and pulsotypes were found between both fly and calf E. coli isolates, suggesting that the calves were the initial source of the antimicrobial resistant strains in fly isolates. Symbovine flies were considered as important reservoirs of antimicrobial resistant E. coli strains at a dairy farm, due to their intensive contact with cattle feces and manure. House martin fecal samples from the same farm contained 4.5% (n=393) of antimicrobial resistant E. coli. House martin isolates displayed different macrorestriction profiles than fly isolates and the significance of house martins as a reservoir and vector of antimicrobial resistant E. coli appears low.

    2007-01-01

    Introduction Since the enactment of the Clean Water Act in 1972, awareness of the quality of the Nation's water has continued to improve. Despite improvements to wastewater-treatment systems and increased regulation on waste discharge, bacterial and chemical contamination is still a problem for many rivers and lakes throughout the United States. Pathogenic microorganism and newly recognized chemical contaminants have been found in waters that are used for drinking water and recreation (Rose and Grimes, 2001; Kolpin and others, 2002). This summary of bacteria and emerging-chemical-contaminant monitoring in the St. Clair River/Lake St. Clair Basin (fig. 1) was initiated by the Lake St. Clair Regional Monitoring Project (LSCRMP) in 2003, in cooperation with the Michigan Department of Environmental Quality (MDEQ), the Counties of Macomb, Oakland, St. Clair, and Wayne, and the U.S. Geological Survey (USGS).

  11. Role of Strouhal number (St) in free swimming

    2012-11-01

    St of 0.2-0.4 has become synonymous with efficient self propulsion. Is it the cause, or an effect? As has been argued by a number of authors, St alone is insufficient to decide optimal motion because many inefficient combinations of amplitude and frequency lead to the same St. In this talk we show a simple ramification of free swimming where the swim speed and St are outputs. The iso-lines for speed, St, and thrust coincide so long as there is no massive leading-edge separation. It appears that St is simply related to how the drag coefficient and geometry of the body relates to the thrust coefficient and geometry of the propulsor. For a given combination of propulsor and body, St of motion is essentially independent of amplitude, frequency, and speed, and is only a function of shape. Some motions are efficient, and some are not. But they all have the same St. Supported by ONR MURI.

  16. Hs3st-A and Hs3st-B regulate intestinal homeostasis in Drosophila adult midgut.

    PubMed

    Guo, Yueqin; Li, Zhouhua; Lin, Xinhua

    2014-11-01

    Intrinsic and extrinsic signals as well as the extracellular matrix (ECM) tightly regulate stem cells for tissue homeostasis and regenerative capacity. Little is known about the regulation of tissue homeostasis by the ECM. Heparan sulfate proteoglycans (HSPGs), important components of the ECM, are involved in a variety of biological events. Two heparin sulfate 3-O sulfotransferase (Hs3st) genes, Hs3st-A and Hs3st-B, encode the modification enzymes in heparan sulfate (HS) biosynthesis. Here we demonstrate that Hs3st-A and Hs3st-B are required for adult midgut homeostasis. Depletion of Hs3st-A in enterocytes (ECs) results in increased intestinal stem cell (ISC) proliferation and tissue homeostasis loss. Moreover, increased ISC proliferation is also observed in Hs3st-B null mutant alone, or in combination with Hs3st-A RNAi. Hs3st-A depletion-induced ISC proliferation is effectively suppressed by simultaneous inhibition of the EGFR signaling pathway, suggesting that tissue homeostasis loss in Hs3st-A-deficient intestines is due to increased EGFR signaling. Furthermore, we find that Hs3st-A-depleted ECs are unhealthy and prone to death, while ectopic expression of the antiapoptotic p35 is able to greatly suppress tissue homeostasis loss in these intestines. Together, our data suggest that Drosophila Hs3st-A and Hs3st-B are involved in the regulation of ISC proliferation and midgut homeostasis maintenance.

  6. Sedimentary Record of Paleodeformation of the Saint Martin Anticline Reveals the Interaction Between Tectonics, Sedimentation Processes and Relative Sea-level Changes: Ganges-Brahmaputra Delta Burma Arc Collision, SE Bangladesh

    Along the Ganges-Brahmaputra Delta Burma Arc collision zone, the Indian plate is converging obliquely with the Burma arc with a shortening GPS rate of 14 mm/yr. In this region tectonics, huge sediment supply from the erosion of the Himalayas (>1 GT/yr) and relative sea level changes interact. The extremely thick sediments of the Ganges-Brahmaputra Delta and Fan (~20 km) are being gradually accreted into a very wide thrust-fold belt along this subduction/collision zone. This interaction has led to the formation of a fold-and-thrust belt and wide accretionary prism that is exposed on land and on the shelf of the Burma forearc. Sedimentary sequence and structure document the seismo-tectonic and sedimentary evolution of St Martin's Island, which is an expression of an anticline in the outer part of the accretion forearc. During late Pleistocene sea-level low stands, the anticline and most of the rest of the shelf were exposed. The anticline ridge could then grow, receiving little erosion by local drainages. At some point during sea level rise, the coast advanced over the ridge and bevelled it. Then sea-level continued to rise and new sediment deposited forming an angular unconformity. A low-relief unconformity, in fact, separates the folded strata below from overlying strata of Holocene age. Where now exposed on the island above sea level, the unconformity is ~8000 y old. At that time, sea level was 30 m below the current level and thus rapid tectonic uplift is necessary to account for its current elevation. Dead coral heads of the species Porities that populate the coast were dated with U-Th (Mondal et al., 2013). They document a megathurst rupture and ~ 2m uplift that occurred during the Great Arakan earthquake in 1762 and further earthquakes are likely at ~ 1100 and 800 AD. Studies of the 1762 rupture suggest that the anticline rises during megathrust earthquakes (~2m) and subsides in the interseismic period (a few mm/yr; Steckler and Mondal 2014). Radiocarbon ages

    Gallbladder cancer (GBC) is an uncommon disease in the majority of the world despite being the most common and aggressive malignancy of the biliary tree. Early diagnosis is essential for improved prognosis; however, indolent and nonspecific clinical presentations with a paucity of pathognomonic/predictive radiological features often preclude accurate identification of GBC at an early stage. As such, GBC remains a highly lethal disease, with only 10% of all patients presenting at a stage amenable to surgical resection. Among this select population, continued improvements in survival during the 21st century are attributable to aggressive radical surgery with improved surgical techniques. This paper reviews the current available literature of the 21st century on PubMed and Medline to provide a detailed summary of the epidemiology and risk factors, pathogenesis, clinical presentation, radiology, pathology, management, and prognosis of GBC.

    Mount St. Helens' eruption has taught geologists invaluable lessons about how volcanoes work. Such information will be crucial in saving lives and property when other dormant volcanoes in the northwestern United States--and around the world--reawaken, as geologists predict they someday will. Since 1912, scientists at the U.S. Geological Survey's Hawaiian Volcano Observatory have pioneered the study of volcanoes through work on Mauna Loa and Kilauea volcanoes on the island of Hawaii. In Vancouver, Wash., scientists at the Survey's Cascades Volcano Observatory are studying the after-effects of Mount St. Helens' catalysmic eruption as well as monitoring a number of other now-dormant volcanoes in the western United States. This paper briefly reviews the similarities and differences between the Hawaiian and Washington volcanoes and what these volcanoes are teaching the volcanologists.

    The St. Louis Site comprises three noncontiguous areas in and near St. Louis, Missouri: the St. Louis Downtown Site (SLDS), the St. Louis Airport Storage Site (SLAPS), and the Latty Avenue Properties. The main site of the Latty Avenue Properties includes the Hazelwood Interim Storage Site (HISS) and the Futura Coatings property, which are located at 9200 Latty Avenue. Contamination at the St. Louis Site is the result of uranium processing and disposal activities that took place from the 1940s through the 1970s. Uranium processing took place at the SLDS from 1942 through 1957. From the 1940s through the 1960s, SLAPS was used as a storage area for residues from the manufacturing operations at SLDS. The materials stored at SLAPS were bought by Continental Mining and Milling Company of Chicago, Illinois, in 1966, and moved to the HISS/Futura Coatings property at 9200 Latty Avenue. Vicinity properties became contaminated as a result of transport and movement of the contaminated material among SLDS, SLAPS, and the 9200 Latty Avenue property. This contamination led to the SLAPS, HISS, and Futura Coatings properties being placed on the National Priorities List (NPL) of the US Environmental Protection Agency (EPA). The US Department of Energy (DOE) is responsible for cleanup activities at the St. Louis Site under its Formerly Utilized Sites Remedial Action Program (FUSRAP). The primary goal of FUSRAP is the elimination of potential hazards to human health and the environment at former Manhattan Engineer District/Atomic Energy Commission (MED/AEC) sites so that, to the extent possible, these properties can be released for use without restrictions. To determine and establish cleanup goals for the St. Louis Site, DOE is currently preparing a remedial investigation/feasibility study-environmental impact statement (RI/FS-EIS). This baseline risk assessment (BRA) is a component of the process; it addresses potential risk to human health and the environment associated wi

  16. ST/HR hysteresis: exercise and recovery phase ST depression/heart rate analysis of the exercise ECG.

    PubMed

    Lehtinen, R

    1999-01-01

    ST segment depression/heart rate (ST/HR) hysteresis is a recently introduced novel computer method for integrating the exercise and recovery phase ST/HR analysis for improved detection of coronary artery disease (CAD). It is a continuous diagnostic variable that extracts the prevailing direction and average magnitude of the hysteresis in ST depression against HR during the first 3 consecutive minutes of postexercise recovery. This article reviews the development and evaluation of this new method in a clinical population of 347 patients referred for a routine bicycle exercise electrocardiographic (ECG) test at Tampere University Hospital, Finland. Of these patients, 127 had angiographically proven CAD, whereas 13 had no CAD according to angiography, 18 had no perfusion defect according to Tc-99m-sestamibi myocardial imaging and single photon emission computed tomography, and 189 were clinically normal with respect to cardiac diseases. For each patient, the values for ST/HR hysteresis, ST/HR index, end-exercise ST depression, and recovery ST depression were determined for each lead of the Mason-Likar modification of the standard 12-lead exercise ECG and maximum value from the lead system (aVL, aVR, and V1 excluded). The area under the receiver operating characteristics curve (ie, the discriminative capacity) of the ST/HR hysteresis was 89%, which was significantly larger than that of the end-exercise ST depression (76%, P < .0001), recovery ST depression (84%, P = .0063) or ST/HR index (83%, P = .0023), indicating the best diagnostic performance of the ST/HR hysteresis in detection of CAD regardless of the partition value selection. Furthermore, the superior diagnostic performance of the method was relatively insensitive to the ST segment measurement point or to the ECG lead selection. These results suggest that the ST/HR hysteresis improves the clinical utility of the exercise ECG test in detection of CAD.

    The US Department of Energy (DOE) is implementing a cleanup program for three groups of properties in the St. Louis, Missouri, area: the St. Louis Downtown Site (SLDS), the St. Louis Airport Site (SLAPS) and vicinity properties, and the Latty Avenue Properties, including the Hazelwood Interim Storage Site (HISS). The general location of these properties is shown in Figure 1; the properties are referred to collectively as the St. Louis Site. None of the properties are owned by DOE, but each property contains radioactive residues from federal uranium processing activities conducted at the SLDS during and after World War 2. The activities addressed in this environmental evaluation/cost analysis (EE/CA) report are being proposed as interim components of a comprehensive cleanup strategy for the St. Louis Site. As part of the Department's Formerly Utilized Sites Remedial Action Program (FUSRAP), DOE is proposing to conduct limited decontamination in support of proprietor-initiated activities at the SLDS, commonly referred to as the Mallinckrodt Chemical Works. The primary goal of FUSRAP activity at the SLDS is to eliminate potential environmental hazards associated with residual contamination resulting from the site's use for government-funded uranium processing activities. 17 refs., 3 figs., 5 tabs.

    Psychological science offers a variety of methods to both understand and intervene when acts of potential racial or ethnic racism, bias or prejudice occur. The Trayvon Martin killing is a reminder of how vulnerable African American men and boys, especially young African American men, are to becoming victims of social inequities in our society. We examine several historical events of racial bias (the Los Angeles civil disturbance after the Rodney King verdict, the federal government's launch of a "War on Drugs" and the killing of Trayvon Martin) to illustrate the ways in which behaviors of racism and race-based discrimination can be viewed from a psychological science lens in the hopes of eliminating and preventing these behaviors. If society is to help end the genocide of African American men and boys then we must broaden our focus from simply understanding instances of victimization to a larger concern with determining how policies, laws, and societal norms serve as the foundation for maintaining implicit biases that are at the root of race-based discrimination, prejudice, bias and inequity. In our call to action, we highlight the contributions that psychologists, particularly racial and ethnic minority professionals, can make to reduce the negative impact of racial and ethnic bias through their volunteer/pro bono clinical efforts.

    Alabama Power operates a series of dams on the Coosa River in east central Alabama. These dams form six reservoirs that provide power generation, flood control, recreation, economic opportunity, and fish and wildlife habitats to the region. The Logan Martin Reservoir is located approximately 45 kilometers east of Birmingham and borders Saint Clair and Talladega Counties. Discharges below the reservoir are controlled by power generation at Logan Martin Dam, and there has been an ongoing concern about the stability of the streambanks downstream of the dam. The U.S. Geological Survey, in cooperation with Alabama Power conducted a scientific investigation of the geomorphic conditions of a 115-meter length of streambank along the Coosa River by using tripod-mounted terrestrial light detection and ranging technology. Two surveys were conducted before and after the winter flood season of 2010 to determine the extent and magnitude of geomorphic change. A comparison of the terrestrial light detection and ranging datasets indicated that approximately 40 cubic meters of material had been eroded from the upstream section of the study area. The terrestrial light detection and ranging data included in this report consist of electronic point cloud files containing several million georeferenced data points, as well as a surface model measuring changes between scans.

    The Alaska earthquake of March 27, 1964, caused widespread geomorphic changes in the Martin-Bering Rivers area-900 square miles of uninhabited mountains, alluvial flatlands, and marshes north of the Gulf of Alaska, and east of the Copper River. This area is at lat 60°30’ N. and long 144°22’ W., 32 miles east of Cordova, and approximately 130 miles east-southeast of the epicenter of the earthquake. The geomorphic effects observed were: (1) earthquake-induced ground fractures, (2) mudvent deposits, (3) “earthquake-fountain” craters, (4) subsidence, (5) mudcones, (6) avalanches, (7) subaqueous landslides, (8) turbidity changes in ice-basined lakes on the Martin River glacier, (9) filling of ice-walled sinkholes, (10) gravel-coated snow cones, (11) lake ice fractures, and (12) uplift accompanied the earthquake. In addition to geomorphic effects, the earthquake affected the animal populations of the area. These include migratory fish, terrestrial mollusks, fur-bearing animals, and man. The Alaska earthquake clearly delineated areas of alluvial fill, snow and rock avalanche corridors, and deltas of the deeper lakes as unsuitable for future construction.

    The St. Clair River and Lake St. Clair form a part of the connecting channel system between Lake Huron and Lake Erie. This report synthesizes existing information on the ecological structure and function of this ecosystem. Chapters include descriptions of climatology, hydrology, and geology of the region; biological characteristics; ecological relationships; and commercial and recreational uses, as well as discussions of management considerations and issues. The St. Clair system provides valuable habitat for migratory waterfowl and fish spawning and nurseries, and contains some of the most extensive emergent wetlands in the region. The system is used for navigation, municipal and industrial waste disposal, recreational boating, fishing and waterfowl hunting. Allowing for multiple human uses while maintaining important waterfowl and fish populations is the greatest challenge facing managers of this system.

    The steroidogenic acute regulatory (StAR) protein regulates the rate-limiting step in steroidogenesis, i.e. the delivery of cholesterol from the outer (OMM) to the inner (IMM) mitochondrial membrane. StAR is a 37-kDa protein with an N-terminal mitochondrial targeting sequence that is cleaved off during mitochondrial import to yield 30-kDa intramitochondrial StAR. StAR acts exclusively on the OMM and its activity is proportional to how long it remains on the OMM. However, the precise fashion and the molecular mechanism in which StAR remains on the OMM have not been elucidated yet. In this work we will discuss the role of mitochondrial fusion and StAR phosphorylation by the extracellular signal-regulated kinases 1/2 (ERK1/2) as part of the mechanism that regulates StAR retention on the OMM and activity.

    The Schedule Organizer, SO (COSMIC Program MSC-21525), Schedule Tracker, ST (COSMIC Program MSC-21526), and Report Generator, SRG (COSMIC Program MSC-21527), are programs that manipulate data base files in ways that are advantageous to scheduling applications. Originally designed for the Space Shuttle flight schedule, the program can be easily modified for other scheduling situations. Schedule Organizer provides a simple method for generating distribution lists. These distribution lists contain readers' names for each task schedule defined by the input files. Schedule Organizer contains a primary menu that is displayed at the beginning of the program. The menu provides options as follows: to write input files to an output distribution file, to change a schedule title field and/or distribution list field, to browse through the schedule and input names file for requested schedule numbers, to create an input names file and a schedule titles file, and to delete input schedule titles and associated names. SO provides a choice of two input files. One file holds 25 groups of up to 25 names for each group. The other file holds 25 records. Each 60-character-long record holds a task schedule title or it is a blank entry. SO creates three output files. One holds the formatted list of schedule titles for printout. Another file holds the formatted distribution list for printout. There is one for each input names file schedule group. The third output file holds the schedule title of the last schedule title file deleted by the user. Schedule Tracker provides an effective method for tracking tasks that are "past due" and/or "near term". ST generates reports for each responsible staff member with one or more assigned tasks that fall within the two listed categories. This enables an engineering manager to monitor tasks assigned to staff by running ST on a weekly basis. ST only lists tasks on reports that have become past due or are scheduled for recent completion (near term

    OBJECTIVE: To study the levels and causes of maternal mortality in St. Petersburg, Russian Federation. METHODS: We collected data about all pregnancy-related deaths in St. Petersburg over the period 1992-2003 using several sources of information. An independent research group reviewed and classified all cases according to ICD-10 and the Confidential Enquiries into Maternal Deaths in the United Kingdom. We tested trends of overall and cause specific ratios (deaths per 100,000 births) for four 3-year intervals using the chi2 test. FINDINGS: The maternal mortality ratio for the study period was 43 per 100,000 live births. A sharp decline of direct obstetric deaths was observed from the first to fourth 3-year interval (49.8 for 1992-94 versus 18.5 for 2001-03). Sepsis and haemorrhage were the main causes of direct obstetric deaths. Among the total deaths from sepsis, 63.8% were due to abortion. Death ratios from sepsis declined significantly from the first to second study interval. In the last study interval (2001-03), 50% of deaths due to haemorrhage were secondary to ectopic pregnancies. The death ratio from thromboembolism remained low (2.9%) and stable throughout the study period. Among indirect obstetric deaths a non-significant decrease was observed for deaths from cardiac disease. Death ratios from infectious causes and suicides increased over the study period. CONCLUSIONS: Maternal mortality levels in St. Petersburg still exceed European levels by a factor of five. Improved management of abortion, emergency care for sepsis and haemorrhage, and better identification and control of infectious diseases in pregnancy, are needed. PMID:16628301

    SciTech Connect

    Peng, Yueng Kay Martin; Cheng, E.T.; Galambos, John D; Cerbone, R. J.

    1995-01-01

    The concept for an ST fusion core that drives a He-cooled, actinide-bearing, molten-salt blanket of moderate power density to generate electricity is examined for the first time. The results show that the fusion core is suited for this purpose and require a level of plasma, power density, engineering, and material performances moderate in comparison with what has been considered desirable for fusion-only power plants. The low aspect ratio of ST introduces a relatively thick, diverted scrape-off layer which leads to reduced heat fluxes at the limiter and divertor tiles. The use of a demountable, water-cooled, single-turn copper center leg for the toroidal field coils enables simplifications of the fusion core configuration and improves overall practicality for future power applications. These result in much reduced size and cost of the fusion core for the transmutation power plant relative to an optimized fusion-only fusion core. Surrounded by a separate tritium-breeding zone, the molten-salt blanket concept is in principle less complex and costly than the thermal breeding blankets for fusion. These combine to effect major reductions in the cost and weight of the power core equipment for the transmutation power plant. The minimum cost of electricity for such a power plant is thus reduced from the best fusion-only counterpart by more than 30%, based on consistent but approximate modeling. The key issues, development steps, and the potential value inherent in the ST fusion core in addressing the world needs for nuclear waste reduction and energy production are discussed.

    Since the establishment of the IEA ST IA in 2007, the world ST research community has grown to 24 ST experiments in seven countries. For the second 5 years of the IA, major upgrades of the NSTX (USA) and MAST (UK) are or will soon be underway aiming to start enhanced experimental research in 2015. Major tests of solenoid-free start-up are addressed by experiments in Japan including QUEST (Kyushu U.), TST-2 (U. Tokyo), and LATE (Kyoto U.), Pegasus (U. Wisconsin), and SUNIST (Tsinghua U., PRC). These aim to develop database to minimize/remove the central solenoid and enable truly compact fusion energy devices. Lithium-only PFCs are tested in LTX (PPPL). The community is considering low to modest-Q applications to fusion energy R&D. These range from small size (R˜0.5m) volume neutron sources delivering several MW fusion neutrons, to medium size (R˜1.0m, 50-MW) fusion science and technology experimental facilities to enable critical R&D needed to develop database for a fusion DEMO and other energy applications. Progress and remaining ST R&D will be summarized.

Here, we report for the first time an outbreak of K. pneumoniae KPC-3 producers in a tertiary-care hospital during 2013. Twenty-seven ertapenem-resistant K. pneumoniae were identified in patients at a tertiary-care hospital during 2013 isolated predominantly from urine (48·1%) and blood (25·9%) cultures. All isolates were highly resistant to β-lactam antibiotics and most showed intermediate resistance to imipenem. The more frequent β-lactamases were TEM- (77·7%), CTX-M- (70·3%) and KPC-type (66·6%). KPC-3 was identified by sequencing. The bla KPC-3 gene was associated with an IncF plasmid, and efficiently transferred to E. coli J53. Pulsed-field gel electrophoresis typing revealed three clusters of isolates which were further characterized by multi-locus sequence typing as ST11, ST15 and ST348. Ertapenem-resistant ST15 was already in circulation in the hospital, related to expression of OmpK36 modified porin, but the other two sequence types had not been previously found in the hospital. We conclude that the IncF plasmid mediated transfer of KPC-3 in the outbreak and that implementation of carbapenemase gene screening in isolates from patients on admission to hospital is advisable in order to control dissemination of these antimicrobial resistance elements.

    2016-01-01

    Differentiation between ischaemic and non-ischaemic transient ST segment events of long term ambulatory electrocardiograms is a persisting weakness in present ischaemia detection systems. Traditional ST segment level measuring is not a sufficiently precise technique due to the single point of measurement and severe noise which is often present. We developed a robust noise resistant orthogonal-transformation based delineation method, which allows tracing the shape of transient ST segment morphology changes from the entire ST segment in terms of diagnostic and morphologic feature-vector time series, and also allows further analysis. For these purposes, we developed a new Legendre Polynomials based Transformation (LPT) of ST segment. Its basis functions have similar shapes to typical transient changes of ST segment morphology categories during myocardial ischaemia (level, slope and scooping), thus providing direct insight into the types of time domain morphology changes through the LPT feature-vector space. We also generated new Karhunen and Lo ève Transformation (KLT) ST segment basis functions using a robust covariance matrix constructed from the ST segment pattern vectors derived from the Long Term ST Database (LTST DB). As for the delineation of significant transient ischaemic and non-ischaemic ST segment episodes, we present a study on the representation of transient ST segment morphology categories, and an evaluation study on the classification power of the KLT- and LPT-based feature vectors to classify between ischaemic and non-ischaemic ST segment episodes of the LTST DB. Classification accuracy using the KLT and LPT feature vectors was 90% and 82%, respectively, when using the k-Nearest Neighbors (k = 3) classifier and 10-fold cross-validation. New sets of feature-vector time series for both transformations were derived for the records of the LTST DB which is freely available on the PhysioNet website and were contributed to the LTST DB.

    Atmospheric pollutants may cause damage to monuments and historical buildings. Besides air contaminants, soluble salts are also responsible for stone deterioration and decay in outdoor and indoor monuments. The problem of how to conserve works of arts thus requires a deep knowledge of contaminants' concentration and distribution inside buildings. In this work, water-soluble ions inside St. Mark's Basilica in Venice were studied, with the aim of understanding their principal source and distribution inside the building. With the aid of Fourier transform infrared spectroscopy and scanning electron microscopy analysis, the interaction between ions and surface's material was also investigated. Ion chromatographic analysis of depositions highlighted a large amount of "deteriorating agents" such as sulphates and chlorides. A possible source in the innermost area of the basilica has been found for formates and nitrates. On the contrary, a decrease of chloride, from the entrance to the innermost area, has been found, which indicates that the source is outside the building. It is emphasized that different contaminants behave differently on different material, and the effect of pollution inside churches and monuments is not easy to predict. Wood and brick seem to react differently than stone and mortar to the damaging action of salts and pollutants. The present work should be considered a useful tool for the future preservation of St. Mark's Basilica in Venice.

    To better characterize neoplasm epizootics in the Great Lakes basin and their association with families of contaminants, we sampled five locations: the Fox and Menominee rivers, Lake Michigan; Munuscong Lake, St. Mary's River; and the Black and Cuyahoga rivers, Lake Erie. Frequencies of external and liver tumors were determined for brown bullhead (Ictalurus nebulosus) from all locations except the Black River and for walleye (Stizostedion vitreum) from the Lake Michigan and St. Mary's River sites. Sediment samples were analyzed for metals, polychlorinated aromatics, and polynuclear aromatic hydrocarbons (PAH). Liver neoplasms occurred in brown bullhead from the Cuyahoga River and Munuscong Lake; brown bullhead captured from Munuscong Lake were older than those collected from the other locations. Brown bullhead from these same two rivers had elevated hepatosomatic indexes. No liver neoplasms were found in brown bullhead from the Fox and Menominee rivers, although polychlorinated aromatics were highest in both Fox River sediment and Fox and Menominee brown bullhead, and arsenic was highest in Menominee River sediment and fish. Liver neoplasms in brown bullhead from the Cuyahoga River fit the prevailing hypothesis that elevated PAH in sediment can induce cancer in wild fish. The cause of the liver neoplasms in Munuscong Lake brown bullhead is undetermined.

    In 2010, about 261 million gallons per day (Mgal/d) of water were withdrawn in St. Bernard Parish, Louisiana, almost entirely from surface-water sources. Industrial use accounted for about 97 percent (253 Mgal/d) of the total water withdrawn. Other categories of use included public supply, rural domestic, and livestock. Water-use data collected at 5-year intervals from 1960 to 2010 indicated that total water withdrawals in the parish ranged from about 138 to 720 Mgal/d, with industrial use of surface water making up the bulk of water withdrawals. The large decline in surface-water withdrawals from 1980 to 1985 was largely attributable to a decrease in industrial use from 654 Mgal/d in 1980 to 127 Mgal/d in 1985. This fact sheet summarizes basic information on the water resources of St. Bernard Parish. Information on groundwater and surface-water availability, quality, development, use, and trends is based on previously published reports listed in the Selected References section.

    Federal laboratories have successfully filled many roles for the public; however, as the 21st Century nears it is time to rethink and reevaluate how Federal laboratories can better support the public and identify new roles for this class of publicly-owned institutions. The productivity of the Federal laboratory system can be increased by making use of public outcome metrics, by benchmarking laboratories, by deploying innovative new governance models, by partnerships of Federal laboratories with universities and companies, and by accelerating the transition of federal laboratories and the agencies that own them into learning organizations. The authors must learn how government-owned laboratories in other countries serve their public. Taiwan`s government laboratory, Industrial Technology Research Institute, has been particularly successful in promoting economic growth. It is time to stop operating Federal laboratories as monopoly institutions; therefore, competition between Federal laboratories must be promoted. Additionally, Federal laboratories capable of addressing emerging 21st century public problems must be identified and given the challenge of serving the public in innovative new ways. Increased investment in case studies of particular programs at Federal laboratories and research on the public utility of a system of Federal laboratories could lead to increased productivity of laboratories. Elimination of risk-averse Federal laboratory and agency bureaucracies would also have dramatic impact on the productivity of the Federal laboratory system. Appropriately used, the US Federal laboratory system offers the US an innovative advantage over other nations.

  14. Nursing heroism in the 21st Century'

    Background The Vivian Bullwinkel Oration honours the life and work of an extraordinary nurse. Given her story and that of her World War II colleagues, the topic of nursing heroism in the 21st century could not be more germane. Discussion Is heroism a legitimate part of nursing, or are nurses simply 'just doing their job' even when facing extreme personal danger? In this paper I explore the place and relevance of heroism in contemporary nursing. I propose that nursing heroism deserves a broader appreciation and that within the term lie many hidden, 'unsung' or 'unrecorded' heroisms. I also challenge the critiques of heroism that would condemn it as part of a 'militarisation' of nursing. Finally, I argue that nursing needs to be more open in celebrating our heroes and the transformative power of nursing achievements. Summary The language of heroism may sound quaint by 21st Century standards but nursing heroism is alive and well in the best of our contemporary nursing ethos and practice. PMID:21324152

    The purpose of this study was to investigate the epidemiological characteristics of carbapenem-resistant Klebsiella pneumoniae (CRKP) in Shanghai Children's Hospital in China. Twenty-two non-duplicate CRKP strains were collected from pediatric patients between March and June in 2014. Antimicrobial susceptibility testing was conducted by the agar dilution method. Beta-lactamases were characterized by polymerase chain reaction (PCR) and DNA sequencing. The transferability of bla NDM-1 was investigated by conjugation experiment. The plasmids bearing antibiotic resistance genes were characterized by S1 nuclease pulsed-field gel electrophoresis (S1-PFGE) and Southern hybridization. Clonal relatedness was evaluated by PFGE and multilocus sequence typing (MLST). The clinical data of patients were retrospectively reviewed. The 22 CRKP strains were resistant to most of the antimicrobial agents tested, except tigecycline and colistin. Overall, 59, 77, and 100 % of these strains were resistant to imipenem, meropenem, and ertapenem, respectively. The bla NDM-1 was positive in 77.3 % (17/22) of the CRKP strains, of which the 16 isolates from inpatients were designated as ST37 (n = 9) and ST76 (n =7) and one isolate from an outpatient belonged to ST846. The 17 bla NDM-1-positive isolates belonged to PFGE type A (n = 9), type C (n = 7), or type B (n = 1). The plasmids bearing bla NDM-1 could be transferred into recipient Escherichia coli J53 through conjugation in 88.2 % (15/17) of the strains. The hybridization results showed that the plasmids carrying the bla NDM-1 gene were approximately 50-240 kb in size. This is the first report of an outbreak caused by NDM-1-producing K. pneumoniae ST76 and ST37 among neonates.

    Acute coronary syndromes in patients with presence of ST-segment elevation in the anterior precordial leads indicates left anterior descending coronary artery occlusion. However, anterior ST-segment elevation has also been described in right ventricular myocardial infarction and is thought to be due to right coronary artery (RCA) occlusion. We present a rare case of isolated RVMI presenting with anterior ST-segment elevation due to proximal occlusion of a right coronary artery that was treated by primary coronary angioplasty. Primary coronary angioplasty and stenting of this artery was performed resulting in resolution of the chest pain and ST- segment elevation. PMID:27190867

    In response to a request from Lockheed Martin Energy Systems, Inc. employees who work at the US Department of Energy Oak Ridge K-25 Site (SIC-9611), Oak Ridge, Tennessee, an investigation was begun into possible exposure to cyanides. The site employed about 4,000 persons. Employees at the K-25 site reported headaches, fatigue, depression, muscle aches, sleeplessness, and muscle tremors. Twenty two employees were interviewed. Air samples were collected and analyzed for cyanides. The results indicated that the employees are not occupationally exposed to hydrogen-cyanide (74908), to cyanide salts or to a wide variety of other compounds that contain the cyanide ion. The authors conclude that no relationship was found between the health problems reported by the workers and any chronic, occupational cyanide intoxication. The authors recommend that risk communication efforts be improved, that Lockheed procedures to investigate this issue be evaluated and that possible nonoccupational sources for cyanide exposure be considered.

    In a letter to his wife from October 14, 1943, Werner Heisenberg describes a fierce clash with Carl Friedrich von Weizsäcker. The sudden conflict raises numerous questions, two of which are tackled here. First: How is now the friendly relationship between Heisenberg and Weizsäcker in the postwar years to be understood? The answer is: as a strategic performance. Second: How are the radical opinions to be explained that Weizsäcker expressed at the time? A thorough reconstruction of the lifelong connection that Weizsäcker maintained with Martin Heidegger and Heidegger's philosophy gives the answer: the young Weizsäcker was fired up by the "utopian" National Socialism with which Heidegger trumped the real existing.

    One hundred four serogroup A meningococci in our collection, isolated in Africa from 1988 to 1999, were characterized by multilocus sequence typing (MLST). Our results and data from the Internet indicate that sequence type 5 (ST-5) strains were responsible for most of African outbreaks and sporadic cases during this period. In 1995, a new clone, characterized by ST-7 sequence, emerged and was responsible for severe outbreaks in Chad (1998) and Sudan (1999). MLST and epidemiologic data indicate that ST-5 and ST-7 represent two virulent clones. These two STs, which belong to subgroup III, differ only in the pgm locus: allele pgm3 is characteristic for ST-5 and allele pgm19 for ST-7. Subgroup III strains were responsible for two pandemics in the 1960s and 1980s. Our data show that the third subgroup III pandemic has now reached Africa. PMID:11747698

    St. Louis City and St. Louis County, Missouri share the same public drinking water source, namely the Missouri River. The all cancer and most organ specific cancer mortality rates have been consistently and considerably higher for St. Louis City than for St. Louis County for the period 1960 through 1972. A change in the St. Louis County water treatment process, which included increasing the chlorine dosage and delaying the addition of ammonia to form chloramines until just prior to distribution, was instituted in 1955. St. Louis City has, by contrast, continued the lower chlorine level and early ammoniation. Trend analysis using the period 1960-67 and 1972-76 showed higher percentage as well as net cancer mortality rate per million increases for large bowel, liver and bladder cancers for St. Louis County. An apparent association between a probable increase in trihalomethane production in the St. Louis County water since 1955 and an increase in these specific cancer rates which exceed the increases in the St. Louis City rates appears to have been shown. This does not imply causality but is in general agreement with other studies which have examined water chlorination and cancer mortality.

    Reasonable evolutionary trends in federal outlays for aerospace research and development predict a continuing decline in real resources (1970 dollars) until the mid eighties, and a growth thereafter to the 1970 level by 2000, still well below the 1966 peak. Employment levels will parallel this trend with no shortage of available personnel foreseen. These trends characterize a maturing industry. Shifts in outlook toward the economic use of resources, rather than minimum risk at any cost, and toward missions aligned with societal needs and broad national goals will accompany these trends. These shifts in outlook will arise in part in academia, and will, in turn, influence engineering education. By 2000, space technology will have achieved major advances in the management of information, in space transportation, in space structures, and in energy. The economics of space systems must be the primary consideration if the space program foreseen for the 21st century is to become an actuality.

    2015-06-01

    Demands for effective vaccines to control parasitic diseases of humans and livestock have been recently exacerbated by the development of resistance of most pathogenic parasites to anti-parasitic drugs. Novel genomic and proteomic technologies have provided opportunities for the discovery and improvement of DNA vaccines which are relatively easy as well as cheap to fabricate and stable at room temperatures. However, their main limitation is rather poor immunogenicity, which makes it necessary to couple the antigens with adjuvant molecules. This paper review recent advances in the development of DNA vaccines to some pathogenic protozoa and helminths. Numerous studies were conducted over the past 14 years of 21st century, employing various administration techniques, adjuvants and new immunogenic antigens to increase efficacy of DNA vaccines. Unfortunately, the results have not been rewarding. Further research is necessary using more extensive combinations of antigens; alternate delivery systems and more efficient adjuvants based on knowledge of the immunomodulatory capacities of parasitic protozoa and helminths.

    The St. Petersburg paradox refers to a gamble of infinite expected value, where people are likely to spend only a small entrance fee for it. There is a huge volume of literature that mostly concentrates on the psychophysics of the game; experiments are scant. Here, rather than focusing on the psychophysics, we offer an experimental, "physical" solution as if robots played the game. After examining the time series formed by one billion plays, we: confirm that there is no characteristic scale for this game; explicitly formulate the implied power law; and identify the type of α-stable distribution associated with the game. We find an α = 1 and, thus, the underlying distribution of the game is a Cauchy flight, as hinted by Paul Samuelson.

    Just as Rome was not built in a day, there are few great inventions and discoveries that can be made overnight. There are always historical circumstances behind them. Laboratory Automation is not an exception. With the end of World War II in 1945 as a turning point, a large volume of American medicine was introduced all over Japan, and clinical laboratory testing which was imported at the same time has taken root and matured. As a result, we can now carry out prompt and fully automated laboratory testing second to none at many hospital laboratories. In this paper, I recall the development and summarize the expansion by focusing on clinical laboratory automation as it has developed in the latter half of the 20th century in Japan. I would feel amply rewarded for my efforts if this paper proved helpful to the young generation. The clinical laboratory of the 21st century rests on their shoulders.

Most effective leaders have one element in common, and that is they are able to keep their teams engaged. If team members are not engaged, they may very well leave the organization. With four generations in the workplace, leaders must adapt and modify their leadership style in order to maintain employee engagement. The ability to lead effectively is based on a number of skills, including communication, motivation, vision, modeling, demonstrating empathy, confidence, persistence, and integrity.

    Volcanic ash samples from four Mount St. Helens' volcanic eruptions were subjected to mineralogical, analytical, and hemolytic studies in order to evaluate their potential for cytotoxicity and fibrogenicity. Plagioclase minerals constituted the major component of the ash with free crystalline silica concentrations ranging from 1.5 to 7.2%. The in vitro hemolytic activity of the volcanic ash was compared to similar concentrations of cytotoxic and inert minerals. The ash was markedly hemolytic, exhibiting an activity similar to chrysotile asbestos, a known fibrogenic agent. The hemolysis of the different ash samples varied with particle size but not with crystalline silica concentration. The results of these studies taken in conjunction with the results of our animal studies indicate a fibrogenic potential of volcanic ash in heavily exposed humans.

    The May 18, 1980, eruption displaced roughly 2.6 km[sup 3] of rock and devastated more than 500 km[sup 2] of forest, mostly to the north of the mountain. Trees within 10--15 km of the mountain peak were burned and uprooted. Beyond that, high winds and flying debris created a blowdown zone. Up to 150 m of rock and ice covered some areas. Accumulations of ash were measured as much as 330 km from the volcano. Mud flows choked nearby rivers and streams. Two years later, the US Congress established the 44,000-hectare Mount St. Helens National Volcanic Monument. The Act essentially directed the USDA Forest Service to allow the area to recover naturally. The paper reviews what changes the ecosystem has been going through since the eruption and the lessons learned that suggest some new resource management techniques.

    On May 18, 1980, Mount St Helens, Washington State's most active volcano, erupted violently. Volcanic eruptions in recent geologic history have demonstrated tremendous environmental impact and caused significant loss of human life. Volcanic ash expelled during the eruption was deposited on much of eastern Washington and had a profound effect on local air quality. Although ash is relatively inert, analysis revealed a small but significant amount of free crystalline silica, the causative agent of silicosis. The fine particles of ash were of respirable size, and there was a remarkable increase in the volume of respiratory cases seen in emergency departments during the period of high airborne particulate levels. Numerous cases of injury indirectly related to the fall of ash were also seen. The long-term effect of exposure to this volcanic ash is unknown. A prompt, coordinated community medical response is necessary to protect the general population from the potential hazard of exposure to volcanic ash.

    The global importance of food safety is not fully appreciated by many public health authorities despite a constant increase in the prevalence of foodborne illness. Numerous devastating outbreaks of salmonellosis, cholera, enterohaemorrhagic Escherichia coli infections, hepatitis A and other diseases have occurred in both industrialized and developing countries. In addition, many of the re-emerging or newly recognized pathogens are foodborne or have the potential of being transmitted by food and/or drinking water. More foodborne pathogens can be expected because of changing production methods, processes, practices and habits. During the early 21st century, foodborne diseases can be expected to increase, especially in developing countries, in part because of environmental and demographic changes. These vary from climatic changes, changes in microbial and other ecological systems, to decreasing freshwater supplies. However, an even greater challenge to food safety will come from changes resulting directly in degradation of sanitation and the immediate human environment. These include the increased age of human populations, unplanned urbanization and migration and mass production of food due to population growth and changed food habits. Mass tourism and the huge international trade in food and feed is causing food and feedborne pathogens to spread transnationally. As new toxic agents are identified and new toxic effects recognized, the health and trade consequences of toxic chemicals in food will also have global implications. Meeting the huge challenge of food safety in the 21st century will require the application of new methods to identify, monitor and assess foodborne hazards.

    The global importance of food safety is not fully appreciated by many public health authorities despite a constant increase in the prevalence of foodborne illness. Numerous devastating outbreaks of salmonellosis, cholera, enterohaemorrhagic Escherichia coli infections, hepatitis A and other diseases have occurred in both industrialized and developing countries. In addition, many of the re-emerging or newly recognized pathogens are foodborne or have the potential of being transmitted by food and/or drinking water.

    This work is concerned with building a three-dimensional (3D) ab-initio models that is capable of predicting the thermal distribution of laser direct joining processes between Polymethylmethacrylate (PMMA) and stainless steel 304(st.st.304). ANSYS® simulation based on finite element analysis (FEA) was implemented for materials joining in two modes; laser transmission joining (LTJ) and conduction joining (CJ). ANSYS® simulator was used to explore the thermal environment of the joints during joining (heating time) and after joining (cooling time). For both modes, the investigation is carried out when the laser spot is at the middle of the joint width, at 15 mm from the commencement point (joint edge) at traveling time of 3.75 s. Process parameters involving peak power (Pp=3 kW), pulse duration (τ=5 ms), pulse repetition rate (PRR=20 Hz) and scanning speed (v=4 mm/s) are applied for both modes.

    SUMMARY In 2008, a previously unknown Escherichia coli clonal group, sequence type 131 (ST131), was identified on three continents. Today, ST131 is the predominant E. coli lineage among extraintestinal pathogenic E. coli (ExPEC) isolates worldwide. Retrospective studies have suggested that it may originally have risen to prominence as early as 2003. Unlike other classical group B2 ExPEC isolates, ST131 isolates are commonly reported to produce extended-spectrum β-lactamases, such as CTX-M-15, and almost all are resistant to fluoroquinolones. Moreover, ST131 E. coli isolates are considered to be truly pathogenic, due to the spectrum of infections they cause in both community and hospital settings and the large number of virulence-associated genes they contain. ST131 isolates therefore seem to contradict the widely held view that high levels of antimicrobial resistance are necessarily associated with a fitness cost leading to a decrease in pathogenesis. Six years after the first description of E. coli ST131, this review outlines the principal traits of ST131 clonal group isolates, based on the growing body of published data, and highlights what is currently known and what we need to find out to provide public health authorities with better information to help combat ST131.
