    Due to its extraordinarily high concentration of known relativistic particle accelerators such as pulsar wind nebula, supernova remnants, dense molecular cloud regions, and the supermassive black hole (Sgr A*); the center of the Milky Way galaxy has long been an ideal target for high energy (HE, 0.1-100 GeV) and very high energy ( VHE, 50 GeV-50 TeV) gamma-ray emission. Indeed, detections of Sgr A* and other nearby regions of gamma-ray emission have been reported by EGRET and Fermi-LAT in the HE band, as well as CANGAROO, Whipple, HESS, VERITAS, and MAGIC in the VHE band. Here we report on the results of extended observations of the region with VERITAS between 2010-2014. Due to the visibility of the source for VERITAS in the Northern Hemisphere, these observations provide the most sensitive probe of gamma-ray emission above 2 TeV in one of the most complicated and interesting regions of our home galaxy.

  4. Spitzer IRS Observations of the Galactic Center

    International Nuclear Information System (INIS)

    We present Spitzer IRS R ∼ 600 spectra (10 - 38 μm) of 38 positions in the Galactic Center (GC), all at the same Galactic longitude of and including the Arches Cluster. Our positions include the Arched Filaments, regions near the Quintuplet Cluster, the ''Bubble'' lying along the same line-of-sight as the molecular cloud MO.13-0.13, and the diffuse interstellar gas along the line of sight at higher Galactic latitudes. From measurements of the [O IV], [Ne II], [Ne III], [Si II], [S III], [Fe II], [Fe III], and H2 S(0), S(1), and S(2) lines we determine the gas excitation and ionic abundance ratios. The main source of excitation is photoionization, with the Arches Cluster ionizing the Arched Filaments and the Quintuplet Cluster ionizing the gas nearby and at lower Galactic latitudes including the far side of the Bubble. In addition, strong shocks ionize gas to O+3 and destroy dust grains, releasing iron into the interstellar medium (ISM); the shock effects are particularly noticeable in the center of the Bubble but the highly ionized gas is present in all positions. The H2 lines are formed both in photodissociation regions in the GC and along the line of sight to the GC

  5. The Galactic Center: possible interpretations of observational data.

    2015-08-01

    There are not too many astrophysical cases where one really has an opportunity to check predictions of general relativity in the strong gravitational field limit. For these aims the black hole at the Galactic Center is one of the most interesting cases since it is the closest supermassive black hole. Gravitational lensing is a natural phenomenon based on the effect of light deflection in a gravitational field (isotropic geodesics are not straight lines in gravitational field and in a weak gravitational field one has small corrections for light deflection while the perturbative approach is not suitable for a strong gravitational field). Now there are two basic observational techniques to investigate a gravitational potential at the Galactic Center, namely, a) monitoring the orbits of bright stars near the Galactic Center to reconstruct a gravitational potential; b) measuring a size and a shape of shadows around black hole giving an alternative possibility to evaluate black hole parameters in mm-band with VLBI-technique. At the moment one can use a small relativistic correction approach for stellar orbit analysis (however, in the future the approximation will not be not precise enough due to enormous progress of observational facilities) while now for smallest structure analysis in VLBI observations one really needs a strong gravitational field approximation. We discuss results of observations, their conventional interpretations, tensions between observations and models and possible hints for a new physics from the observational data and tensions between observations and interpretations.References1.

    Fuller, Franklin D; Senlik, S Seckin; Wilcox, Daniel E; Ogilvie, Jennifer P

    2013-01-01

    Photosynthesis powers life on our planet. The basic photosynthetic architecture comprises antenna complexes to harvest solar energy and reaction centers to convert the energy into a stable charge separated state. In oxygenic photosynthesis, the initial charge separation event occurs in the photosystem II reaction center; the only known natural enzyme that uses solar energy to split water. Energy transfer and charge separation in photosynthesis are rapid and have high quantum efficiencies. Recently, nonlinear spectroscopic experiments have suggested that electronic coherence may play a role in energy transfer efficiency in antenna complexes. Here we report the observation of coherence in the photosystem II reaction center by two dimensional electronic spectroscopy. The frequencies of the observed coherences match exciton difference frequencies and/or known vibrational modes of the photosystem II reaction center. These observations raise questions about the possible role of electronic and/or vibrational coheren...

  9. Extinction toward the galactic center from observations of interstellar lines

    International Nuclear Information System (INIS)

    A substantial galactic gradient in the 13Co--to-dust ratio has been suggested recently by Blitz and Shu. They used the 13CO emission seen toward the galactic center and a local calibration of the 13CO--to-emission ratio to predict the extinction to the galactic center. The result is far greater than the extinction deduced from infrared observations. In this paper, H2CO absorption observations against Sgr A are used to select the molecular material lying in front of the galactic center, and a similar analysis is carried out. The ratio of visual extinction to equivalent width of the 6 cm line of H2CO is similar for several nearby interstellar clouds. The value for the ratio A/sub v//W(H2CO) is approx.12 mag (km s-1)-1. When this ratio is applied to published data for the galactic center an extinction of 13CO emission toward the galactic center reveals that the results for this molecule are similar to those for H2CO if the result of Dickman is used to determine A/sub v/. The large value that Blitz and Shu deduced for A/sub v/ from 13CO is a consequence of their inclusion of molecular components which do not lie in front of the infrared cluster. We find no compelling evidence for a substantial gradient in the 13CO--to-dust ratio. If the assumptions used by Solomon, Scoville, and Sanders to deduce cloud masses are used instead of the result of Dickman, extinctions are found which are 3--5 times greater than those deduced from H2CO. consequently, the mass estimates of Solomon et al. appear to be 3--5 times too high

  10. The Universe Observation Center: an educational center devoted to Astronomy in Catalonia

    Science.gov (United States)

    Fernández, D.

    The Universe Observation Center (in Catalan language, Centre d'Observació de l'Univers, COU) is located in close proximity to the Montsec Astronomical Observatory (Observatori Astronòmic del Montsec, OAM), in eastern Catalonia (Spain). Both centers comprise the Montsec Astronomical Park (Parc Astronòmic Montsec, PAM), managed by the Consorci del Montsec. Montsec Mountain remains the finest location for astronomical observation in Catalonia, as demonstrated by a site-testing campaign conducted by the Astronomy and Meteorology Department of the University of Barcelona. The COU consists of a Central Building (including a permanent exhibition and three classrooms possessing broadband Internet access), the Telescope Park (two astronomical domes equipped with medium-size telescopes, a coelostat for solar observation, and a portable telescope park), the Eye of Montsec (a digital planetarium and, at the same time, an extremely innovative platform for sky observation) and the Garden of the Universe (a tour of the land surrounding the COU, visiting several areas within it). The COU will offer to the Spanish academic community a host of fascinating and unique activities in the fields of astronomy and geology. The Center is open not only to students (from primary school through university), but also to amateur astronomers, people interested in science and the general public.

  11. The Universe Observing Center a modern center to teach and communicate astronomy

    2011-06-01

    The Universe Observing Center is one of the parts of the Parc Astronòmic Montsec (PAM). PAM is an initiative of the Catalan government, through the Consorci del Montsec (Montsec Consortium), to take advantage of the capabilities and potential of the Montsec region to develop scientific research, training and outreach activities, particularly in the field of Astronomy. The choice of the Montsec mountains to install the PAM was motivated by the magnificent conditions for observing the sky at night; the sky above Montsec is the best (natural sky free of light pollution) in Catalonia for astronomical observations. The PAM has two main parts: the Observatori Astronòmic del Montsec (OAdM) and the Universe Observing Center (COU). The OAdM is a professional observatory with an 80-cm catadioptric telescope (Joan Oró Telescope). This telescope is a robotic telescope that can be controlled from anywhere in the world via the Internet. The COU is a large multipurpose center which is intended to become an educational benchmark for teaching and communicate astronomy and other sciences in Catalonia. The management of the COU has three main goals: 1) Teach primary and secondary school students in our Educational Training Camp. 2) Teach university students housing the practical astronomy lectures of the universities. 3) Communicate astronomy to the general public. The COU comprises special areas for these purposes: the Telescopes Park with more than 20 telescopes, a coelostat for solar observations and two dome containing full-automated telescopes. The most special equipment is ``The Eye of Montsec'', with its 12m dome containing a multimedia digital planetarium and a platform for direct observation of the sky and the environment. During 2009 we expect around 10000 visitors in Montsec area to enjoy science with Montsec dark skies and an special natural environment.

  13. The ATA Galactic Center Survey: SETI Observations in 2009

    Science.gov (United States)

    Backus, Peter R.; Allen Telescope Array Team

    2010-01-01

    We report on SETI observations of a region near the Galactic Center during 2009 with the Allen Telescope Array. The survey covers galactic longitude 357° to 7° and latitude ± 1° with a grid of 3500 positions corresponding to a synthesized beam of 8’ by 3'. For each position, we searched the "Water Hole” portion of the microwave spectrum (1420 - 1720 MHz) with a resolution of 0.7 Hz for continuous and pulsed signals with frequency drift rates of up to ±1 Hz/sec and bandwidths less than 10 Hz. In order to preserve the coherence of narrow band signals, we avoid pointing within 60° of the Sun. In its current stage, the Allen Telescope Array (ATA-42) is an array of 42 six-meter dishes with three dual-polarization beamformers. The beams observe independent positions within the field of view at the same frequency allowing each to serve as an "off” position for the other beam. This is a new approach to RFI mitigation. While SETI observations proceed, two independently tunable correlators are used to image the field of view. These "commensal” observations are discussed in another poster in this session ("The ATA Galactic Center Survey: Slow Radio Transients” by P. Williams). The first phase of the ATA was funded through generous grants from the Paul G. Allen Family Foundation. UC Berkeley, the SETI Institute, the National Science Foundation (Grant No. 0540599), Sun Microsystems, Xilinx, Nathan Myhrvold, Greg Papadopoulos, and other corporations and individual donors contributed additional funding.

    A number of different classes of stars, sub-stellar objects, and stellar remnants exhibit variability at radio wavelengths on time scales ranging from sub-seconds to hours. The direction toward the Galactic center not only has the highest stellar densities in the Galaxy, but also appears to have a range of interstellar scattering properties that may aid in the detection of new, radio-selected transient events. We have examined all archival VLA observations of the Galactic center field from 1985 to 2005 at 5 GHz and 8.4 GHz for a total of 214 hours of integration time, spanning 99 observations at 5 GHz with a typical area of 4.41E-4 square degrees and 116 observations at 8.4 GHz with a typical area of 8E-4 square degrees. We used a pipeline to search for transient events down to the shortest time scales allowed by the data (typically 10 seconds) by generating model-subtracted visibility data for each observation and then imaging the residual visibilities over short time intervals to search for outlier events. We present one radio transient event and at least 7 other promising candidates with significances ranging from 5.6 to 10.2 sigma that have passed all our tests, and discuss the possible source classes for these candidates and the event rate implications. We acknowledge support from the National Science Foundation for this work. Part of this research was carried out at the Jet Propulsion Laboratory, California Institute of Technology, under a contract with the National Aeronautics and Space Administration.

    We have used the Kuiper Airborne Observatory (KAO) and the Anglo-Australian Telescope (AAT) to investigate the nature of the filamentary radio emission from the Galactic center region. KAO observations of the FIR line and continuum emission from the radio peak G0.095+0.012 and the E2 thermal radio filament northeast of the Galactic center can be produced by numerous nearby stars with T(sub eff) approx. 35,000 K; these can account for both the FIR luminosity and the excitation of the gas. Much of the FIR continuum and most of the strong (Si II) (34.8 micron) line emission are probably produced in the ionized gas of the filament. The FIR (O III) 52 and 88 micron lines imply an electron density of a few hundred; when compared with the radio emission measure, this implies the filament is roughly tubular or somewhat flattened in the plane of the sky. The (O III) and (S III) lines show higher excitation associated with the filament, and suggest that exciting stars may be located within the filaments and/or southeast of the E2 filament. AAT observations in the near infrared (NIR) in fact reveal a nearby cluster of hot stars southeast of the E2 filament. Additional hot stars, not identifiable from their NIR spectra, are likely to be present. These stars and those in the cluster can plausibly produce the observed radio and FIR emission in the region. The morphology of the filament is not explained by existing information however.

  16. Center determination for trailed sources in astronomical observation images

    2014-11-01

    Images with trailed sources can be obtained when observing near-Earth objects, such as small astroids, space debris, major planets and their satellites, no matter the telescopes track on sidereal speed or the speed of target. The low centering accuracy of these trailed sources is one of the most important sources of the astrometric uncertainty, but how to determine the central positions of the trailed sources accurately remains a significant challenge to image processing techniques, especially in the study of faint or fast moving objects. According to the conditions of one-meter telescope at Weihai Observatory of Shandong University, moment and point-spread-function (PSF) fitting were chosen to develop the image processing pipeline for space debris. The principles and the implementations of both two methods are introduced in this paper. And some simulated images containing trailed sources are analyzed with each technique. The results show that two methods are comparable to obtain the accurate central positions of trailed sources when the signal to noise (SNR) is high. But moment tends to fail for the objects with low SNR. Compared with moment, PSF fitting seems to be more robust and versatile. However, PSF fitting is quite time-consuming. Therefore, if there are enough bright stars in the field, or the high astronometric accuracy is not necessary, moment is competent. Otherwise, the combination of moment and PSF fitting is recommended.

    Alkali halides such as calcium fluoride all have color center defects that absorb light in the visible region. Using a moncochromator equipped, aberration corrected, scanning transmission electron microscope (STEM) we recorded spectra showing the time evolution of the generation of F and H centers in calcium fluoride. The final stage of electron beam irradiation is the formation of metallic calcium nanoparticles. High resolution low loss spectra for the Vacuum Ultraviolet region were also recorded. - Highlights: • Color center defects clearly identified by high resolution EELS of CaF{sub 2}. • Both F Centers and H Centers produced by electron beam irradiation. • Ultimately metallic calcium is left as evidenced by plasmon and density of states. • High resolution low loss (VUV) spectra also recorded.

    2013-12-01

    The Observing System Monitoring Center (OSMC), a project funded by the National Oceanic and Atmospheric Administration's Climate Observations Division (COD), exists to join the discrete 'networks' of In Situ ocean observing platforms -- ships, surface floats, profiling floats, tide gauges, etc. - into a single, integrated system. The OSMC is addressing this goal through capabilities in three areas focusing on the needs of specific user groups: 1) it provides real time monitoring of the integrated observing system assets to assist management in optimizing the cost-effectiveness of the system for the assessment of climate variables; 2) it makes the stream of real time data coming from the observing system available to scientific end users into an easy-to-use form; and 3) in the future, it will unify the delayed-mode data from platform-focused data assembly centers into a standards- based distributed system that is readily accessible to interested users from the science and education communities. In this presentation, we will be focusing on the efforts of the OSMC to provide interoperable access to the near real time data stream that is available via the Global Telecommunications System (GTS). This is a very rich data source, and includes data from nearly all of the oceanographic platforms that are actively observing. We will discuss how the data is being served out using a number of widely used 'web services' (including OPeNDAP and SOS) and downloadable file formats (KML, csv, xls, netCDF), so that it can be accessed in web browsers and popular desktop analysis tools. We will also be discussing our use of the Environmental Research Division's Data Access Program (ERDDAP), available from NOAA/NMFS, which has allowed us to achieve our goals of serving the near real time data. From an interoperability perspective, it's important to note that access to the this stream of data is not just for humans, but also for machine-to-machine requests. We'll also delve into how we

    Full Text Available Hydatidiform moles (HMs are abnormal human pregnancies with vesicular chorionic villi, imposing two clinical challenges; miscarriage and a risk of gestational trophoblastic neoplasia (GTN. The parental type of most HMs are either diandric diploid (PP or diandric triploid (PPM. We consecutively collected 154 triploid or near-triploid samples from conceptuses with vesicular chorionic villi. We used analysis of DNA markers and/or methylation sensitive-MLPA and collected data from registries and patients records. We performed whole genome SNP analysis of one case of twinning (PP+PM.In all 154 triploids or near-triploids we found two different paternal contributions to the genome (P1P2M. The ratios between the sex chromosomal constitutions XXX, XXY, and XYY were 5.7: 6.9: 1.0. No cases of GTN were observed. Our results corroborate that all triploid human conceptuses with vesicular chorionic villi have the parental type P1P2M. The sex chromosomal ratios suggest approximately equal frequencies of meiosis I and meiosis II errors with selection against the XYY conceptuses or a combination of dispermy, non-disjunction in meiosis I and meiosis II and selection against XYY conceptuses. Although single cases of GTN after a triploid HM have been reported, the results of this study combined with data from previous prospective studies estimate the risk of GTN after a triploid mole to 0% (95% CI: 0-1,4%.

    2015-06-01

    Brain fag was originally described as a culture-bound syndrome among West African students. The term "brain fag" literally means "brain fatigue." Available literature indicates that brain fag symptoms usually present in formal academic settings when African students are required to transit to a reliance on written literature (as opposed to more traditional oral forms of information transmission) and to adapt to westernized, individualistic systems of education that, at times, oppose the values of relatively collectivistic African societies. Based on detailed observation of two typical and two nontypical cases of brain fag, the authors suggest that the syndrome may not be solely related to tensions in the academic sphere, but may function more generally as an expression of psychological distress that results from societal pressures that exceed the coping capacity of the individual. The brain fag symptoms, including lack of concentration, sensations of internal heat in the head and body, heaviness, and multiple somatic complaints, may constitute a defensive process which helps prevent a full-fledged decompensation.

    During the period July, 1977 to September, 1979, rainfall was collected in the vicinity of the Kennedy Space Center and subjected to appropriate chemical analysis for purposes of characterization of general composition and acidity. Results obtained form the basis for future comparisons, should significant alteration of the chemical composition of rain occur during the space shuttle era. Acidity extremes calculated on a monthly basis from event samples collected from five sites within a 200 sq km area varied from pH 5.1 in November, 1977, and April, 1978 to pH 4.3 in July, 1978 and July, 1979. Weighted average pH for the entire period was 4.55. Acidity was due to the presence of sulfuric and nitric acids. The mole ratio of excess SO4(-2):NO3(-) was typically greater than one. Monthly weighted average Cl(-) concentrations ranged from 20-240 micromoles/liter. The Cl(-):Na(+) ratio was slightly lower than that present in sea water.

    This paper presents examples of magnetosheath cavities in Cluster spacecraft observations. The cavities are accompanied by high energy particles in the magnetosheath and characterized by depressed magnetic fields and densities. Flow speeds decrease and temperatures increase within the cavities. All magnetosheath parameters show increased variability within the cavities when the energetic particle flux is high. We predict outward motion of the magnetopause boundary in respons...

    Jatropha curcas L. is an inedible plant belonging to the Euphorbiaceae family that is growing in subtropical zones of all continents. We report a series of 24 cases of poisoning with J. curcas seeds or fruits reported to poison centers in Paris and Marseille between December 2000 and June 2014. Fifteen adults and 9 children ingested J. curcas seeds or fruits. All patients experienced gastrointestinal disorders, within the first hours following ingestion: nausea, vomiting, diarrhea and abdominal pain. Laboratory investigations performed in 10 patients revealed minor abnormalities: CK elevation (8 cases), dehydration (5 cases) with moderate elevation of serum creatinine levels (3 cases), and mildly increased serum bilirubin (8 cases). Complete remission of all clinical signs was observed within 48 hours in the 20 cases for which the outcome was known. Previously published cases of J. curcas poisoning were very similar to ours: As in our series, gastrointestinal disorders were always present. They were sometimes associated with neurological or cardiovascular signs, and hepatic or renal disorders; these were generally interpreted as complications of severe gastroenteritis, although direct toxic effects could not be formally excluded. In most cases, simple supportive measures were sufficient to ensure complete recovery within 24-48 hours. J Curcas poisoning incidence is certainly increasing because the plant is cultivated to produce biodiesel and is now largely present in most subtropical countries. As a consequence, local health professionals should be informed of the toxic properties of this plant. PMID:25925815

  18. Evidence for activity at the Galactic center based on low frequency radio continuum observations

    International Nuclear Information System (INIS)

    Aperture synthesis observations of the galactic center region at 123.0 and 110.6 MHz reveal striking asymmetric steep spectrum (α≤-0.8) radio lobes. The northern galactic lobe (NGL) appears to be a unique galactic source and cannot be easily classified as an SNR, extragalactic source, or a foreground object. The southern ''lobe'' appears directly linked to the galactic center and has been identified by Yusef-Zadeh et al. as a low energy jet emanating from Sgr-A. We present here new 80 MHz observations of an expanded region around the galactic center obtained one year after the initial set of observations. Excellent morphological agreement between these separate sets of observations confirm the persistence of the NGL as the dominant emission feature in the entire region at these frequencies. The similarities of this source with the jet feature suggest a common origin. Together with the compact nonthermal source located at the galactic center, the properties and geometry of these sources resemble the radio lobes observed in the nuclei of Seyfert galaxies

    The Reformed Teaching Observation Protocol (RTOP; Swada, et al., 2002) has been used by a trained team of On the Cutting Edge (CE) observers to characterize the degree of student-centered teaching in US college and university geoscience classrooms. Total RTOP scores are derived from scores on 25 rubric items used to characterize teaching practices in categories of lesson design, content delivery, student-instructor and student-student interactions. More than 200 classroom observations have been completed by the RTOP team in undergraduate courses at a variety of US institution types (e.g., community colleges, research universities). A balanced mix of early career, mid-career, and veteran faculty are included, and the study examines class sizes ranging from small (80 students). Observations are limited to one class session and do not include laboratories or field activities. Data include RTOP scores determined by a trained observer during the classroom observation and an online survey in which the observed instructors report on their teaching practices. RTOP scores indicate that the observed geoscience classes feature varying degrees of student-centered teaching, with 30% of observed classes categorized as teacher-centered (RTOP scores ≤30), 45% of observed classes categorized as transitional classrooms (RTOP scores 31-49) and 25% are student-centered (RTOP scores ≥ 50). Instructor self-report survey data and RTOP scores indicate that geoscience faculty who have participated in one or more CE professional development event and use the CE website have an average RTOP score of 49, which is significantly higher (> 15 points) than the average score of faculty who have not participated in CE events and have not used the website. Approximately 60% of student-centered classes (those with high RTOP scores) use some traditional lecture nearly every day, but are also are likely to include an in-class activity or group discussion (e.g. Think-Pair-Share). More than 50% of

    Full Text Available One of the important learning objectives of our bachelor course on "Techniques in Decision Support Systems" is to develop understanding of core decision making process in real-life business situations. The conventional teaching methods are unable to explain complexities of real-life business. Although the classroom discussions can be effective to understand general factors, such as opportunity cost, return on investment, etc. affecting business decisions, the effects of factors like dynamic business environment, incomplete information, time pressure etc. can not be truly explained through such simple discussions. In this paper, we describe our experience of adopting student-centered, role-based, case study to deal with this situation. The interactive case-based study not only provided students with experiential learning, but also gave them liberty to test their thoughts. As a result, we observed improved students' learning as well as improved grades. In addition, this approach made classes more dynamic and interesting.

    Full Text Available Human Resource Management (HRM faces difficulties in small businesses which derive from the small size and absence of adequate financial resources. Many authors have investigated the changed version of HRM in small enterprises which is some deal different with HRM in large enterprises. But in Iran researches are not interested in investigating human resource management in the field of small businesses and this encouraged me to perform this research. At first, this study has reviewed HRM policies and practices in small and medium enterprises (SMEs in the world. Then Iranian medical imaging centers have been selected as knowledge SMEs and some related managerial information has been collected from them by observation and interview. The obtained findings are about the role that HRM plays in today Iranian SMEs in the case of medical imaging centers. In this chapter the type of Human Resource Management which is accomplished in medical imaging enterprises in Iran is discovered and you can find the mistakes performed by their managers. These findings are analyzed based on literatures. In the conclusion part, some differences between western and Iranian models are proved and the study concludes that most of the owner managers in medical imaging centers in Iran could not execute HRM practices, even if they knew them or not. At last, some key points are presented as final recommendations to Iranian medical imaging SMEs in order to help them to improve their efficiency in the future.

    The Galactic Center Ridge has been observed extensively in the past by both GeV and TeV gamma-ray instruments revealing a wealth of structure, including a diffuse component as well as the point sources G0.9+0.1 (a composite supernova remnant) and Sgr A* (believed to be associated with the supermassive black hole located at the center of our Galaxy). Previous very high energy (VHE) gamma-ray observations with the H.E.S.S. experiment have also detected an extended TeV gamma-ray component along the Galactic plane in the >300 GeV gamma-ray regime. Here we report on observations of the Galactic Center Ridge from 2010-2014 by the VERITAS telescope array in the >2 TeV energy range. From these observations we 1.) provide improved measurements of the differential energy spectrum for Sgr A* in the >2 TeV gamma-ray regime, 2.) provide a detection in the >2 TeV gamma-ray emission from the composite SNR G0.9+0.1 and an improved determination of its multi-TeV gamma-ray energy spectrum, 3.) report on the detection of VER J1...

    The Galactic center is an interesting region for high-energy (0.1-100 GeV) and very-high-energy (E > 100 GeV) gamma-ray observations. Potential sources of GeV/TeV gamma-ray emission have been suggested, e.g., the accretion of matter onto the supermassive black hole, cosmic rays from a nearby supernova remnant (e.g. SgrA East), particle acceleration in a plerion, or the annihilation of dark matter particles. The Galactic center has been detected by EGRET and by Fermi/LAT in the MeV/GeV energy band. At TeV energies, the Galactic center was detected with moderate significance by the CANGAROO and Whipple 10 m telescopes and with high significance by H.E.S.S., MAGIC, and VERITAS. We present the results from three years of VERITAS observations conducted at large zenith angles resulting in a detection of the Galactic center on the level of 18 standard deviations at energies above ~2.5TeV.

    The peril from hurricanes to Space Operations Centers is real and is forecast to continue; Katrina, Rita, and Wilma of 2005 and Charley, Frances, Ivan, and Jeanne of 2004 are sufficient motivation for NASA to develop a multi-Center plan for preparedness and response. As was demonstrated at SSC (Stennis Space Center) in response to Hurricane Katrina, NASA Centers are efficiently activated as local command centers, playing host to Federal and State agencies and first responders to coordinate and provide evacuation, relocation, response, and recovery activities. Remote sensing decision support provides critical insight for managing NASA infrastructure and for assisting Center decision makers. Managers require geospatial information to manage the federal city. Immediately following Katrina, SSC s power and network connections were disabled, hardware was inoperative, technical staff was displaced and/or out of contact, and graphical decision support tools were non-existent or less than fully effective. Despite this circumstance, SSC EOC (Emergency Operations Center) implemented response operations to assess damage and to activate recovery plans. To assist Center Managers, the NASA ASP (Applied Sciences Program) made its archive of high-resolution data over the site available. In the weeks and months after the immediate crisis, NASA supplemented this data with high-resolution, post-Katrina imagery over SSC and much of the affected coastal areas. Much of the high-resolution imagery was made available through the Department of Defense Clear View contract and was distributed through U.S. Geological Survey Center for Earth Resources Observation and Science "Hurricane Katrina Disaster Response" Web site. By integrating multiple image data types with other information sources, ASP applied an all-source solutions approach to develop decision support tools that enabled managers to respond to critical issues, such as expedient access to infrastructure and deployment of resources

    Full Text Available Abstract Background We aimed to examine the co-authorship networks in three successful Iranian academic research centers, in order to find the association between the scientific productivity and impact indicators with network features in a case study. Methods We searched for English articles of the three research centers. We drew co-authorship maps of each center and calculated social network measures. Results The collaboration networks in centers shared many structural features, including a "star-like" pattern of relations. Centers with more successful scientific profile showed denser and more cooperative networks. Key figures in each center were interviewed for their understandings of the reasons for the emergence of these patterns. Conclusion Star shape network structure and dependency on a single big member is a common feature observed in our case study. Scientific output measures correlate with the network structure of research centers. Network analysis seems a useful method to explore the subtle scientific contexts in research organizations.

    Laparoscopic splenectomy (LS) is nowadays considered as the gold standard for most hematological diseases where splenectomy is necessary, but many questions still remain. The aim of this study was to analyze our 5-years experiences consisting of 48 consecutive LS cases in order to assess the optimal approach and the feasibility of the procedure also in malignant diseases and unusual cases such as a primary spleen lymphoma, a big splenic artery aneurism, or a spleen infarct due to a huge pancreatic pseudo-cyst. Forty-eight consecutive patients underwent LS from January 2006 to January 2011 with at least 1-year follow-up. Clinical data and immediate outcome were retrospectively recorded; age, diagnosis, operation time, perioperative transfusion requirement, conversion rate, accessory incision, hospital stay, and complications were analyzed. We had 14 cases of malignant splenic disease, the most frequent malignant diagnosis was non-Hodgkin's lymphoma (12/14, 85.7 %). Splenomegaly (interpole diameter (ID) >20 cm) was observed in 12 cases (25 %) and massive splenomegaly (ID >25 cm) in 3 cases (6.25 %). Conversion to laparotomy occurred in two patients (4.16 %), both associated to uncontrollable bleeding in patients with splenomegaly. Mean operative time was 138 ± 22 min. Mean hospital stay was 4.5 days. Postoperative morbidity rate was 8.8 % for the benign group and 35.7 % in the malignant group. Mortality occurred in 1/48 patients (2.08 %), as a result of overwhelming post-splenectomy infection (OPSI). LS can be performed safely for malignant splenic disease and splenomegaly without any statistically significant increase of morbidity and mortality rate. Conversion rate is increased for massive splenomegaly. LS should be considered as the preferential approach even in patients with malignant disease, splenomegaly, or unusual cases. Massive splenomegaly should be considered as relative contraindication to LS even at experienced centers. PMID:23355349

    The Incorporated Research Institutions for Seismology (IRIS) is funded by the National Science Foundation (NSF) to operate the facilities to generate, archive, and distribute seismological data to research communities in the United States and internationally. The IRIS Data Management System (DMS) is responsible for the ingestion, archiving, curation and distribution of these data. The IRIS Data Management Center (DMC) manages data from more than 100 permanent seismic networks, hundreds of temporary seismic deployments as well as data from other geophysical observing networks such as magnetotelluric sensors, ocean bottom sensors, superconducting gravimeters, strainmeters, surface meteorological measurements, and in-situ atmospheric pressure measurements. The IRIS DMC has data from more than 20 different types of sensors. The IRIS DMC manages approximately 100 terabytes of primary observational data. These data are archived in multiple distributed storage systems that insure data availability independent of any single catastrophic failure. Storage systems include both RAID systems of greater than 100 terabytes as well as robotic tape robots of petabyte capacity. IRIS performs routine transcription of the data to new media and storage systems to insure the long-term viability of the scientific data. IRIS adheres to the OAIS Data Preservation Model in most cases. The IRIS data model requires the availability of metadata describing the characteristics and geographic location of sensors before data can be fully archived. IRIS works with the International Federation of Digital Seismographic Networks (FDSN) in the definition and evolution of the metadata. The metadata insures that the data remain useful to both current and future generations of earth scientists. Curation of the metadata and time series is one of the most important activities at the IRIS DMC. Data analysts and an automated quality assurance system monitor the quality of the incoming data. This insures data

    The presentation will provide the technical specifications, the systems engineering processes, and preliminary results from laboratory and field tests, as the National Data Buoy Center (NDBC) undertakes a fundamental and broad transformation (sea-change) of its ocean observing systems on moored buoys. This transformation is necessary to gain efficiencies in maintaining operational ocean observation networks and to increase their reliability, which will reduce maintenance costs. The presentation will also compare and contrast existing and planned systems. The Self-Contained Ocean Observations Payload (SCOOP) takes advantage of the advances in communications and small, efficient, multi-purpose sensors to reduce the size and costs of systems and expand the suite of available real-time ocean observations. The communications will allow NDBC to increase the precision and decrease the latency of the observations. The hallmark of SCOOP is the modularity of the payloads that allow NDBC to host specialized systems, for the oceanographic research community, which may include observing ocean acidification and algal blooms, and tracking marine life, alongside its standard suite of meteorological, oceanographic, and wave systems. SCOOP will include cameras, primarily to document vandalism incidents, but they can also serve to corroborate many of the automatic observations. The two-year integration project - focused on recapitalization of NDBC's network of Hurricane Weather buoys - is aided by NDBC's 40 years of experience with marine observations and its continually improving approach to testing. Testimony to the rigor of NDBC's development and test procedures is that the World Meteorological Organization and the Intergovernmental Ocean Commission have designated NDBC as the first Regional Marine Instrumentation Center (RMIC). Integral to the fielding of these new systems is a Mission Control Center (MCC) performing the real-time, specialized monitoring and analyses and

    Recently, the Galactic Center has been reported to be a source of very high energy (VHE) gamma-rays by the VERITAS, CANGAROO and HESS experiments. The energy spectra as measured by these experiments show substantial differences. In this Letter we present MAGIC observations of the Galactic Center, resulting in the detection of a differential gamma-ray flux consistent with a steady, hard-slope power law, described as dN/(dA dt dE) = (2.9+/-0.6)*10^{-12} (E/TeV)^{-2.2+/-0.2} cm^{-2}s^{-1}TeV^{-1}. The gamma-ray source is centered at (Ra, Dec)=(17h 45m 20s, -29deg 2'. This result confirms the previous measurements by the HESS experiment and indicates a steady source of TeV gamma-rays. We briefly describe the observational technique used, the procedure implemented for the data analysis, and discuss the results in the perspective of different models proposed for the acceleration of the VHE gamma-rays.

    Full Text Available Synthetic cannabinoid use has risen at alarming rates. This case series describes 11 patients exposed to the synthetic cannabinoid, MAB-CHMINACA who presented to an emergency department with life-threatening toxicity including obtundation, severe agitation, seizures and death. All patients required sedatives for agitation, nine required endotracheal intubation, three experienced seizures, and one developed hyperthermia. One developed anoxic brain injury, rhabdomyolysis and died. A significant number were pediatric patients. The mainstay of treatment was aggressive sedation and respiratory support. Synthetic cannabinoids pose a major public health risk. Emergency physicians must be aware of their clinical presentation, diagnosis and treatment.

    In 1966, Cohen and Fano (1966 Phys. Rev. 150 30) suggested that one should be able to observe the equivalent of Young’s double slit interference if the double slits were replaced by a diatomic molecule. This suggestion inspired many experimental and theoretical studies searching for double slit interference effects both for photon and particle ionization of diatomic molecules. These effects turned out to be so small for particle ionization that this work proceeded slowly and evidence for interference effects were only found by looking at cross section ratios. Most of the early particle work concentrated on double differential cross sections for heavy particle scattering and the first evidence for two-center interference for electron-impact triple differential cross section (TDCS) did not appear until 2006 for ionization of H2. Subsequent work has now firmly established that two-center interference effects can be seen in the TDCS for electron-impact ionization of H2. However, in spite of several experimental and theoretical studies, similar effects have not been found for electron-impact ionization of N2. Here we report the first evidence for two-center interference for electron-impact ionization of N2.

  19. Exploratory trials, confirmatory observations: A new reasoning model in the era of patient-centered medicine

    Directory of Open Access Journals (Sweden)

    Sacristán José A

    2011-04-01

    Full Text Available Abstract Background The prevailing view in therapeutic clinical research today is that observational studies are useful for generating new hypotheses and that controlled experiments (i.e., randomized clinical trials, RCTs are the most appropriate method for assessing and confirming the efficacy of interventions. Discussion The current trend towards patient-centered medicine calls for alternative ways of reasoning, and in particular for a shift towards hypothetico-deductive logic, in which theory is adjusted in light of individual facts. A new model of this kind should change our approach to drug research and development, and regulation. The assessment of new therapeutic agents would be viewed as a continuous process, and regulatory approval would no longer be regarded as the final step in the testing of a hypothesis, but rather, as the hypothesis-generating step. The main role of RCTs in this patient-centered research paradigm would be to generate hypotheses, while observations would serve primarily to test their validity for different types of patients. Under hypothetico-deductive logic, RCTs are considered "exploratory" and observations, "confirmatory". Summary In this era of tailored therapeutics, the answers to therapeutic questions cannot come exclusively from methods that rely on data aggregation, the analysis of similarities, controlled experiments, and a search for the best outcome for the average patient; they must also come from methods based on data disaggregation, analysis of subgroups and individuals, an integration of research and clinical practice, systematic observations, and a search for the best outcome for the individual patient. We must look not only to evidence-based medicine, but also to medicine-based evidence, in seeking the knowledge that we need.

    Full Text Available The article reports a case and review of the literature of endophthalmitis presenting as isolated retinal vasculitis. A 26-year-old male was observed to have white-centered retinal hemorrhages and retinal vasculitis following an occult scleral perforation. At presentation, the visual acuity was 20/60. With clinical suspicion of early endophthalmitis, he underwent wound exploration, scleral tear repair, vitreous biopsy and administration of intravitreal antibiotics. Microbiology evaluation revealed significant presence of methicillin-resistant coagulase-negative Staphylococcus epidermidis. Final visual acuity improved to 20/20 at 6 weeks postoperatively. Literature search revealed eight similar cases, all of them due to Staphylococcus species. Retinal vasculitis and white-centered retinal hemorrhages can be a presenting sign of early endophthalmitis, especially with non-fulminant pathogens like S. epidermidis.

  2. Primary care nursing role and care coordination: an observational study of nursing work in a community health center.

    2012-05-01

    Care coordination is a core element of the Patient-Centered Medical Home and requires an effective, well educated nursing staff. A greater understanding of roles and tasks currently being carried out by nurses in primary care is needed to help practices determine how best to implement care coordination and transform into PCMHs. We conducted an observational study of primary care nursing in a Community Health Center by creating a classification schema for nursing responsibilities, directly observing and tracking nurses' work, and categorizing their activities. Ten nurses in eight different practice sites were observed for a total of 61 hours. The vast majority of nursing time was spent in vaccine and medication administration; telephone work; and charting and paper work, while only 15% of their time was spent in activity that was classified broadly as care coordination. Care coordination work appeared to be subsumed by other daily tasks, many of which could have been accomplished by other, lesser trained members of the health care team. Practices looking to implement care coordination need a detailed look at work flow, task assignments, and a critical assessment of staffing, adhering to the principal of each team member working to the highest level of his or her education and license. Care coordination represents a distinct responsibility that requires dedicated nursing time, separate from the day to day tasks in a busy practice. To fully support these new functions, reimbursement models are needed that support such non visit-based work and provide incentives to coordinate and manage complex cases, achieve improved clinical outcomes and enhance efficiency of the health system. This article describes our study methods, data collection, and analysis, results, and discussion about reorganizing nursing roles to promote care coordination. PMID:22686111

    The use of plants for bioregenerative life support for space missions was first studied by the US Air Force in the 1950s and 1960s. Extensive testing was also conducted from the 1960s through the 1980s by Russian researchers located at the Institute of Biophysics in Krasnoyarsk, Siberia, and the Institute for Biomedical Problems in Moscow. NASA initiated bioregenerative research in the 1960s (e.g., Hydrogenomonas) but this research did not include testing with plants until about 1980, with the start of the Controlled Ecological Life Support System (CELSS) Program. The NASA CELSS research was carried out at universities, private corporations, and NASA field centers, including Kennedy Space Center (KSC). The project at KSC began in 1985 and was called the CELSS Breadboard Project to indicate the capability for plugging in and testing various life support technologies; this name has since been dropped but bioregenerative testing at KSC has continued to the present under the NASA s Advanced Life Support (ALS) Program. A primary objective of the KSC testing was to conduct pre-integration tests with plants (crops) in a large, atmospherically closed test chamber called the Biomass Production Chamber (BPC). Test protocols for the BPC were based on observations and growing procedures developed by university investigators, as well as procedures developed in plant growth chamber studies at KSC. Growth chamber studies to support BPC testing focused on plant responses to different carbon dioxide (CO2) concentrations, different spectral qualities from various electric lamps, and nutrient film hydroponic culture techniques.

    Full Text Available Background and ObjectivesExperience with vesicoureteral reflux (VUR differs in different centers and there are lots of controversies surrounding this issue. The aim of this study was to evaluate Spontaneous resolution and prognosis of the disease among Iranian children.MethodsIn this case series study, 1278 children with urinary tract infection and visited at pediatric nephrology clinic in Tehran, Iran during 1999-2007 were studied. Primary VUR was found in 533 Patients. Following the diagnosis, the patients received prophylactic antibiotic and were annually followed with radionucleo cystography (RNC. Patients underwent surgery in case the medical treatment failed (breakthrough infection or new renal scar formation.Results533 patients with VUR were studied. Patients’ mean age with VUR was 3.7±2.4 years (range: 2 days to 18 years old. During an average follow-up duration of 3.3+2.2 years, spontaneous resolution was observed in 40% of 279 patients who had follow-up RNCs. The mean interval between VUR diagnosis and spontaneous resolution was 1.5+ 1 years (range: 2 months to 6 years. The resolution rate was decreased with increment of reflux grade so that for grades I to V, VUR was resolved in 63%, 57%, 27%, 22% and 10% of the cases, respectively. Anti reflux surgery was performed in 27(10% of patients during follow-up.ConclusionBased on the excellent results obtained from clinical therapy using low dose antibiotics, it is recommended that VUR grades 1 to 4 be managed medically with low-dose oral antibiotic prophylaxis and close follow-ups.Keywords: Urinary Tract Infection; Vesico-Ureteral Reflux; Spontaneous Resolution; Child.

  5. Infrared-excess Source DSO/G2 Near the Galactic Center: Theory vs. Observations

    2015-01-01

    We monitored the Dusty S-cluster object (DSO/G2) during its closest approach to the Galactic Center supermassive black hole in 2014 with ESO VLT/SINFONI. We report on our findings, i.e. ionized-hydrogen emission from the DSO that remains spatially compact before and after the peribothron passage. The detection of DSO/G2 object as a compact single-peak emission line source is in contradiction with the original hypothesis of a core-less cloud that is necessarily tidally stretched, hence producing double-peak emission line profile around the pericentre passage. This strengthens the evidence that the DSO/G2 source is a dust-enshrouded young star. The accretion of material from the circumstellar disc onto the stellar surface can contribute significantly to the emission of Br$\\gamma$ line as well as to the observed large line width of the order of 10 angstroms.

    We review the current understanding of the cosmological evolution of supermassive black holes in galactic centers elucidated by X-ray surveys of active galactic nuclei (AGNs). Hard X-ray observations at energies above 2 keV are the most efficient and complete tools to find "obscured" AGNs, which are dominant populations among all AGNs. Combinations of surveys with various flux limits and survey area have enabled us to determine the space number density and obscuration properties of AGNs as a function of luminosity and redshift. The results have essentially solved the origin of the X-ray background in the energy band below ∼10 keV. The downsizing (or anti-hierarchical) evolution that more luminous AGNs have the space-density peak at higher redshifts has been discovered, challenging theories of galaxy and black hole formation. Finally, we summarize unresolved issues on AGN evolution and prospects for future X-ray missions. PMID:25971656

    2015-01-01

    Since the early work by Ashkin in 1970, optical trapping has become one of the most powerful tools for manipulating small particles, such as micron sized beads or single atoms. The optical trapping mechanism is based on the interaction energy of a dipole and the electric field of the laser light. In atom trapping, the dominant contribution typically comes from the allowed optical transition closest to the laser wavelength, whereas for mesoscopic particles it is given by the bulk polarizability of the material. These two different regimes of optical trapping have coexisted for decades without any direct link, resulting in two very different contexts of applications: one being the trapping of small objects mainly in biological settings, the other one being dipole traps for individual neutral atoms in the field of quantum optics. Here we show that for nanoscale diamond crystals containing artificial atoms, so-called nitrogen vacancy (NV) color centers, both regimes of optical trapping can be observed at the same...

    2013-01-01

    In 2011, we discovered a compact gas cloud ("G2") with roughly three Earth masses that is falling on a near-radial orbit toward the massive black hole in the Galactic Center. The orbit is well constrained and pericenter passage is predicted for early 2014. Our data beautifully show that G2 gets tidally sheared apart due to the massive black hole's force. During the next months, we expect that in addition to the tidal effects, hydrodynamics get important, when G2 collides with the hot ambient gas around Sgr A*. Simulations show that ultimately, the cloud's material might fall into the massive black hole. Predictions for the accretion rate and luminosity evolution, however, are very difficult due to the many unknowns. Nevertheless, this might be a unique opportunity in the next years to observe how gas feeds a massive black hole in a galactic nucleus.

  10. Observations of the galactic center and search for exotic signals with H.E.S.S

    International Nuclear Information System (INIS)

    Very high energy γ-ray astronomy is a new and young physics field which aims to study the origin of cosmic rays and their acceleration process inside various astrophysical objects such as pulsars, black holes or supernovae remnants. This is also a promising way to search for exotic high energy phenomena and unknown physics. This dissertation deals with three fundamental physics topics closely connected to very high energy γ-ray astronomy: particle acceleration in the vicinity of a supermassive black hole, primordial black holes evaporation, and indirect searches for (dark matter. Each of these topics is studied with data collected by the H.E.S.S (High Energy Stereoscopic System) instrument, an imaging Cherenkov array dedicated for the detection of very high energy γ-rays above 100 GeV. In the first part of the dissertation, we present a rapid overview of the field of very high energy γ-ray astronomy. A precise description of the H.E.S.S detector is then given as well as the data analysis techniques used to derive the results that are subsequently presented. The first subject is related to black hole astrophysics and concerns observations of the Galactic Center region with H.E.S.S. The source of the γ-ray emission discovered in 2004 toward this region is unidentified. A precise determination of the source energy spectrum and variability with new data is reported here. Results are then compared with models of particle acceleration in the vicinity of Sgr A*, the supermassive black hole located at the dynamical center of the Galaxy. In a second subject, the whole data collected with H.E.S.S is used to search for the signature o f primordial black holes evaporation through their emission of bursts of γ-rays. Primordial black holes are exotic objects that might have formed in the early stages of the Universe. As the bulk of the γ-ray emission is likely to originate from a standard astrophysical mechanism, the Galactic Center is not an ideal target for the indirect

    2016-06-01

    Abstract: We present 19.7, 25.2, 31.5, and 37.1 μm maps of the Thermal Arched Filament region in the Galactic Center taken with the Faint Object Infrared Camera for the SOFIA Telescope (FORCAST) with an angular resolution of 3.2-3.8". We calculate the integrated infrared luminosity of the Arched Filaments and show that they are consistent with being heated by the nearby Arches cluster. Additionally, using our observations, we infer dust temperatures (75 – 90 K) across the Arched Filaments which are remarkably consistent over large spatial scales (∼ 25 pc). We discuss the possible geometric effects needed to recreate this temperature structure. Additionally, we compare the observed morphology of the Arches in the FORCAST maps with the Paschen-α emission in the region to study what fraction of the infrared emission may be coming from dust in the HII region versus the PDR beneath it. Finally, we use Spitzer/IRAC 8 μm data to look for spatial variations in PAH abundance in the rich UV environment of the young (~2-4 Myr) and massive Arches cluster.

    We present results from our spectroscopic study, using the Infrared Spectrograph (IRS) onboard the Spitzer Space Telescope, designed to identify massive young stellar objects (YSOs) in the Galactic Center (GC). Our sample of 107 YSO candidates was selected based on IRAC colors from the high spatial resolution, high sensitivity Spitzer/IRAC images in the Central Molecular Zone (CMZ), which spans the central ~300 pc region of the Milky Way Galaxy. We obtained IRS spectra over 5um to 35um using both high- and low-resolution IRS modules. We spectroscopically identify massive YSOs by the presence of a 15.4um shoulder on the absorption profile of 15um CO2 ice, suggestive of CO2 ice mixed with CH3OH ice on grains. This 15.4um shoulder is clearly observed in 16 sources and possibly observed in an additional 19 sources. We show that 9 massive YSOs also reveal molecular gas-phase absorption from CO2, C2H2, and/or HCN, which traces warm and dense gas in YSOs. Our results provide the first spectroscopic census of the mas...

  18. Massive vectors and loop observables: the $g-2$ case

    CERN Document Server

    Biggio, Carla; Di Luzio, Luca; Ridolfi, Giovanni

    2016-01-01

    We discuss the use of massive vectors for the interpretation of some recent experimental anomalies. In order for loop observables, such as for example the muon $g-2$, to be finite (and hence to be predictable in terms of a renormalizable Lagrangian) the massive vector must be embedded into a spontaneously broken extended gauge symmetry. The latter, however, typically imposes strong constraints on the mass of the new vector boson and for the muon $g-2$ it basically rules out, barring the case of abelian gauge extensions, the explanation of the discrepancy in terms of a single vector extension of the standard model. We finally comment on the use of massive vectors for $B$-meson decay and di-photon anomalies.

    Full Text Available Hypertrophic cardiomyopathy belongs to a group of hereditary diseases due to sarcomere gene mutation. This abnormality is characterized by the development of symmetric or asymmetric hypertrophy of left ventricular myocardium with its normal contractile function or hypercontractility. Authors provide a brief overview of variants of hypertrophic cardiomyopathy and phenocopies of this disease, when structural changes in the heart are not the result of classic sarcomere gene mutation. In patients with some phenocopies concentric left ventricular hypertrophy can transform into its dilatation with reduced contractility. Such variant of hypertrophic cardiomyopathy is presented in the first clinical observation. The second case shows that hypertrophic cardiomyopathy can be one of the symptoms of the disease with other reasons for poor outcome.

  20. Observations on the radiochemical control of radiopharmaceuticals at tajoura nuclear research center (TNRC)

    International Nuclear Information System (INIS)

    Production of radioisotopes for the radiopharmaceutical purposes is the main task of Tajoura nuclear center. During the analysis of the 131I- radioactive solution which was produced using the so-called dry method, the following has been observed : in order to reduce the cost and the time of analytical cycle or time used for the radiochemical purity (RCP), a spot test has been used to indicate the position of the radioactivity in the chromatogram rather than using autoradiographing or the x-ray films. This method was based on the reaction between I2 and starch to give a blue color at different Rf values I2 is liberated by I- oxidation (H2O2) or by IO-3 reaction with SCN- in the presence of HCl. A simple and fast test for the estimation of the content in the radioactive sample has been elaborated.This method was based on the reduction of Te (IV) or (VI) to Te metal using SnCI2 in a alkaline media. The detection limit of the elaborated method was found to be 131 I- buffer solution, and 16.0 m S for Na CI saline solution were obtained

    Thirty-eight cases of infective endocarditis (IE) were observed between 1976 and 1989 (1.3% of all cardiac disease). Thirty two cases were retained for study based on Von Reyn's criteria: 28 native valve endocarditis (27 left and 1 right heart valves) of which 18 occurred on previously undiseased valves (56.3%); 4 cases of left heart prosthetic valve endocarditis. The average age of the patients was 27.5 +/- 14 years and the group comprised 24 women and 8 men (p less than 0.001). Blood cultures were negative in 13 cases, revealed a Gram negative pathogen in 8 cases, a streptoccocus in 3 cases. Blood cultures were not performed in 2 cases. The IE was acute in 18 cases (56.7%) and subacute in 14 cases (43.7%). The dominant clinical signs were of massive and sometimes acute valvular regurgitation (mitral: 21 cases; aortic: 10 cases; mitral and aortic: 3 cases; tricuspid: 1 case). Twenty-six patients had cardiac failure (81.2%): LVF: 15 cases, congestive cardiac failure: 10 cases, RVF: 1 case. The other complications were embolic: cerebral (3 cases), mesenteric (1 case), pulmonary (4 cases). Antibiotic therapy was prescribed in all patients; surgery was required in 9 cases. There were 12 fatalities (37.5%), 10 in the medically treated group and 2 in the surgical group (p less than 0.05). The results show that the prognosis of IE in underdeveloped regions remains poor. Effective strategies of early diagnosis and treatment are urgently required to reduce the high mortality. Prophylaxis of IE should commence with measures to counter the portals of entry of the pathogens and the valvular sequellae of acute rhumatic fever. PMID:2126713

    Full Text Available Introduction: Studies regarding etiological spectrum of recurrent jaundice are rare. We conducted this study to identify the causes of recurrent jaundice in a tertiary care center. Materials and Methods: Frequency of different causes of recurrent jaundice was assessed from 130 patients attended General Medicine Department over a period of 3 years. Recurrent jaundice was considered when patients had more than one episodes of jaundice with serum bilirubin ≥3 mg/dl since childhood. Recurrent jaundice was diagnosed from past medical records, records of follow-up visits, and current clinical presentation. Causes were identified from past and present medical records of history, clinical and laboratory examinations. Results: Causes of recurrent jaundice included prehepatic (30%, hepatic (59.23%, and posthepatic (10.77 % disorders. Prehepatic disorders were Gilbert′s syndrome (GS, megaloblastic anemia, autoimmune haemolytic anemia, Wilson′s disease, G6PD deficiency, etc. Hepatic disorders were exacerbations of alcoholic hepatitis, hepatitis B and C, autoimmune hepatitis, congestive cardiac failure, sarcoidosis, benign recurrent intrahepatic cholestasis, eclampsia, pregnancy induced cholestasis, falciparum malaria, drug induced liver injury (DILI, etc. Posthepatic causes were choledocholithiasis, recurrent pancreatitis, periampullary carcinoma, choledochal cyst, ascariasis, hemobilia, HIV cholangiopathy, autoimmune pancreatitis, etc. Prehepatic jaundice cases were younger. The highest level of total bilirubin was seen in alcoholic hepatitis, DILI, and hepatitis B. Alcoholic hepatitis was the most common cause of recurrent jaundice (19.23%. GS was the most common prehepatic cause. Mean age was lowest in GS and highest in DILI. Conclusion: Etiological spectrum of recurrent jaundice includes many prehepatic, hepatic or posthepatic disorders. A larger study may enlarge the spectrum.

    Background and Objectives

    Experience with vesicoureteral reflux (VUR differs in different centers and there are lots of controversies surrounding this issue. The aim of this study was to evaluate Spontaneous resolution and prognosis of the disease among Iranian children.

     

    Methods

    In this case series study, 1278 children with urinary tract infection and visited at pediatric nephrology clinic in Tehran, Iran during 1999-2007 were studied. Primary VUR was found in 533 Patients. Following the diagnosis, the patients received prophylactic antibiotic and were annually followed with radionucleo cystography (RNC. Patients underwent surgery in case the medical treatment failed (breakthrough infection or new renal scar formation.

     

    Results

    533 patients with VUR were studied. Patients’ mean age with VUR was 3.7±2.4 years (range: 2 days to 18 years old. During an average follow-up duration of 3.3+2.2 years, spontaneous resolution was observed in 40% of 279 patients who had follow-up RNCs. The mean interval between VUR diagnosis and spontaneous resolution was 1.5+ 1 years (range: 2 months to 6 years. The resolution rate was decreased with increment of reflux grade so that for grades I to V, VUR was resolved in 63%, 57%, 27%, 22% and 10% of the cases, respectively. Anti reflux surgery was performed in 27(10% of patients during follow-up.

     

    Conclusion

    Based on the excellent results obtained from clinical therapy using low dose antibiotics, it is recommended that VUR grades 1 to 4 be managed medically with low-dose oral antibiotic prophylaxis and close follow-ups.

    Conjoined twins are so rare that most obstetricians will not be personally exposed to such cases during their professional lifetimes. The authors report three cases including one of dicephalic parapagus conjoined twins and two thoracopagus conjoined twins in the present tertiary medical center, and discuss the diagnosis and management details. They also review the incidence, embryological, diagnostic, obstetrical, and prognostic aspects of conjoined twins. Regular antenatal visits and serial ultrasound scanning are crucial for early diagnosis of conjoined twins, optimal obstetric management and perinatal preparation still remain challenging, and multidisciplinary cooperation is urgently needed.

    According to the World Meteorological Organization (WMO) Global Atmosphere Watch (GAW) Strategic Plan: 2008-2015 (WMO, 2009a) WMO/GAW pays attention to systematical improvement of the quality of observations at global or regional monitoring sites. To ensure the comparability and compatibility of the measurements worldwide it is essential to maintain a traceability chain to the primary standard in the different laboratories around the world as well as to establish a quality control system. Sulfur hexafluoride (SF6), is reported to be very rare in the atmosphere at the global averaged annual mole fraction of about 7 ppt, it is one of the greenhouse gases regulated by Kyoto protocol and is increasing at a rate of 0.22 ppt yr-1. Development of a working (or transfer) standard with very low concentration of SF6 requires expert technologies and several knowhow of gas metrology. In order to meet the Data Quality Objective (DQO), the KMA has cooperated with the Korea Research Institute of Standards and Science (KRISS), which is the National Metrology Institute in South Korea. So long as the Central Calibration Laboratory (CCL) for SF6 was established, the Korea Meteorological Administration (KMA) is now trying to take another step forward to systematically support GAW stations in improving their traceability and quality system for SF6, thereby making a contribution to the WMO/GAW. Through hosting the World Calibration Center for SF6, which is one of GAW facilities, KMA will contribute to harmonization of the global SF6 observations in the long run. This work performed to demonstrate some measurement results on SF6 which complies with the DQOs and is traceable to the WMO mole fraction scale for SF6. In order to produce a working standard which is traceable to the WMO scale, we developed highly precise method of a Gas Chromatography/Electron Capture Detector (GC/ECD) calibrated against the five cylinders (from NOAA, 2011) of the WMO scale.

    Native Science Field Centers (NSFCs) were created to engage youth and adults in environmental science activities through the integration of traditional Native ways of knowing (understanding about the natural world based on centuries of observation including philosophy, worldview, cosmology, and belief systems of Indigenous peoples), Native languages, and Western science concepts. This paper focuses on the Blackfeet Native Science Field Center, the Lakota Native Science Field Center, and the Wind River Native Science Field Center. One of the long-term, overarching goals of these NSFCs was to stimulate the interest of Native American students in ways that encouraged them to pursue academic and career paths in science, technology, engineering, and mathematics (STEM) fields. A great deal can be learned from the experiences of the NSFCs in terms of effective educational strategies, as well as advantages and challenges in blending Native ways of knowing and Western scientific knowledge in an informal science education setting. Hopa Mountain—a Bozeman, Montana-based nonprofit—partnered with the Blackfeet Community College on the Blackfeet Reservation, Fremont County School District #21 on the Wind River Reservation, and Oglala Lakota College on the Pine Ridge Reservation to cooperatively establish the Native Science Field Centers. This paper presents a profile of each NSFC and highlights their program components and accomplishments.

    Chronic pain is a serious problem in Spain. This multicenter, epidemiological 3-month follow-up study investigates pain management efficacy in Spanish centers using patient satisfaction criteria. 3,414 eligible adult patients (65,6% female) with moderate to severe chronic pain from 146 pain centers were included. Patient satisfaction was assessed based onto question 18 of Spanish healthcare barometer-CSI. Pain evolution (Brief Pain Inventory-Short Form (BPI-SF) and visual analog scale (VAS)), quality of life/EuroQol-5, and pain control expectations fulfillment were also assessed. Mean age was 61.3 years. 64.4% of participating centers employed multidisciplinary pain management approach. After 3 months, mean patient satisfaction was 7.8 (1–10) on the CIS barometer. Medical staff received the highest scores, whereas waiting for tests, appointment request to appointment date time, and waiting times at the center the lowest. Mean pain decreased from 7.4 to 4.0; BPI-SF intensity decreased from 6.5 to 3.8; pain control expectations were met in 78.7% of patients; EuroQoL-5D utility index increased from 0.37 to 0.62, p Spanish centers care; 80% had their pain control expectations met. Quality of life improved remarkably: 71% felt moderately to significantly better. However, waiting times need improvement.

    Midocean ridge eruptions offer rare opportunities to study the creation of new ocean crust and the accelerated release of heat and chemicals into the ocean. Only 7 such events have been documented since the first observation of eruption-induced fluid discharge in 1986. Their hallmark is “event plumes,” symmetrical boluses of hydrothermally rich water typically ~0.5 km thick and 5-20 km in diameter. Past sampling of such plumes has occurred from 10 days to months after an eruption. In Nov. 2008 on the Northeast Lau Spreading Center, we detected not a typical event plume but a uniquely different series of young, apparently eruption-generated plumes. At 0700 UTC on 20 Nov., a CTD tow detected layers of thin (0.6), oxidation-reduction potential (ORP or “Eh”) (>250 mv), temperature (ΔT >0.7°C), and H2 (6873 nM) anomalies, plus abundant glass shards (>50μm). These characteristics imply a very young plume. 21 hours later, another tow mapped abundant plume layers extending from 900 m depth to the seafloor, marking the probable eruption site as 15.39°S, 174.25°W. High H2 (up to 9031 nM) and low 3He (68 δ(3He)%) in the shallowest plumes suggests their source was magma-seawater contact. In contrast, low H2 (33 nM) and high 3He (up to 146 δ(3He)%) in the deeper plumes implies their source was a more evolved hydrothermal fluid. CO2 values were high in all plumes. By 24 Nov. shallow plumes were absent above the eruption site, with only weak remnants found a few km south. By 27 Nov. no plumes shallower than 1450 m were found within our ~5 km sampling radius. Bottom-water temperature anomalies over the eruption site declined during the same time frame. Three near-bottom tows (15-50 mab) consistently identified bottom waters with significant ΔT between 15.405° and 15.380°S (~4 km) along the ridge crest. Maximum ΔT seen on the first tow (0400 21 Nov.) was ~0.7°C, declining to ~0.3°C after 18 hrs. By 1000 27 Nov. the zone of enhanced ΔT had constricted to ~2 km

    Many particle dark matter models predict that the dark matter undergoes cascade annihilations, i.e. the annihilation products are 4-body final states. In the context of model-independent cascade annihilation models, we study the compatibility of the dark matter interpretation of the Fermi- LAT Galactic center gamma-ray emission with null detections from dwarf spheroidal galaxies. For canonical values of the Milky Way density profile and the local dark matter density, we find that the dark matter interpretation to the Galactic center emission is strongly constrained. However, uncertainties in the dark matter distribution weaken the constraints and leave open dark matter interpretations over a wide range of mass scales.

    From January 1979 through March 1988, our regional poison center, located many hundreds of miles from the nearest coastal salt water, documented 23 cases of envenomation by "Lionfish" (members of genus Pterois). All cases involved specimens which were maintained in the homes of amateur aquarists. A study of patient epidemiology showed the following: patient's sex 91.3% male, 8.7% female; patients ages ranged from 17 to 50 years with an average age for males of 29.8 years and 35 years for females; the site of the envenomation accident was always in the home; the only part of the body envenomated was the hand or finger; and all of the patients were symptomatic. Symptoms noted included sharp pain, swelling, redness, bleeding, nausea, numbness, joint pain, anxiety, headache, disorientation, and dizziness. One patient had a complication of cellulitis. Treatment provided included immersion of the effected area in hot water at 40 C for 60 to 90 min, analgesics, tetanus toxoid, and antibiotics. There were no deaths noted and treatment proved effective in all cases. This paper also discusses the natural history, clinical effects, and current treatment for envenomations from these beautiful but dangerous venomous fish, which can cause poisoning exposures that are likely to be encountered by poison centers anywhere in the world.

  3. Student-Centered Teaching Meets New Media: Concept and Case Study

    2002-10-01

    Full Text Available There exists empirical evidence proving that students who are given the freedom to explore areas based on their personal interests, and who are accompanied in their learning by a supportive, understanding facilitator, not only achieve superior academic results but also develop socially and grow personally. However, pure Student-Centered Teaching is more demanding in terms of communication, organization, as well as the provision of learning material. Thus, the basic idea underlying our paradigm is to combine Student-Centered Teaching with eLearning in order to exploit the advantages of the two approaches. We refer to this combined style as Student-Centered eLearning (SCeL. Strongly simplified, the computer takes over the task of providing information, while presence phases can be used for giving the content more meaning by means of transparent, open, respectful and empathic interactions within the group. Our case study indicates that Student-Centered eLearning has the potential of reducing the increased demands of Student-Centered Teaching in the long run, while fully retaining all its benefits, such as deeper learning processes, personal growth, social skills, and a higher degree of flexibility. Furthermore, the maturity for life-long learning is cultivated. In this paper we introduce our concept and derive first hypotheses on the conditions under which our paradigm appears most effective. While potential continuations of our studies are manifold, we intend to employ SCeL in the course of the new curriculum of the medical faculty of GrazUniversity where a Virtual Medical Campus (http://vmc.uni-graz.at is currently being developed.

  4. H110 alpha observations of Sagittarius A West: Ionized gas at peculiar velocities at the galactic center

    1995-01-01

    We present Very Large Array measurements of H110 alpha radio recombination line emission from Sgr A West with a resolution of 11 x 20 arcsec. These observations detected a number of new kinematic components showing a dramatically different velocity field than expected from circular motion of ionized gas in Sgr A West about the dynamical center of the Galaxy. Recent high-resolution molecular observations show a cloud of absorbing gas at -180 km/s within 30 arcsec of the Galactic center. We find evidence of an ionized counterpart to this highly blueshifted molecular gas. This result places this highly blueshifted neutral gas in a hot UV dominated environment of the Galactic center. We suggest that the blueshifted clouds are photoionized externally by the intense UV radiation field at the Galactic center. We also detect H110 alpha emission from large-scale linear features known as the 'streamers', which run primarily perpendicular to the Galactic plane and lie exterior to the 'three-arm' spiral structure of Sgr A West and the circumstellar disk. These observations support an earlier suggestion that the streamers are thermal features whose kniematics deviate from circular motion.

  14. Radiotherapy of primary cutaneous follicle center lymphoma: case report and review of literature

    International Nuclear Information System (INIS)

    Primary cutaneous follicle center lymphoma is an indolent primary cutaneous B-cell lymphoma originating from the follicle center cells, composed of a combination of centrocytes (small and large cleaved cells) and centroblasts (large noncleaved cells) with a follicular, follicular/diffuse, or diffuse growth pattern. Lesions are mostly located on the head, neck and trunk. A case is presented of a 56-year-old male patient with primary cutaneous follicle center lymphoma, with lesions involving the skin of the back, shoulders, presternal area and right forearm. As the patient presented a disseminated cutaneous form of the disease that involved several anatomical regions, complete work-up was followed by superficial fractionated radiotherapy of eight fields in VI expositions, with total irradiation dose of 1400 cGy upon the following fields: right and left pectoral region, left and right shoulders, right suprascapular region, and proximal third of the right forearm. Total irradiation dose applied upon each field for the lesions located on the left and right side of the back was 1500 cGy. This therapy resulted in significant reduction of visible tumor. The patient was regularly followed up on outpatient basis for 12 months of radiotherapy, being free from local recurrence and systemic spread of the disease

    Viehmann, T; Schödel, R; Moultaka, J; Straubmeier, C; Pott, J U

    2004-01-01

    We present near-infrared H-, K-, L- and M-band photometry of the Galactic Center from images obtained at the ESO VLT in May and August 2002, using the NAOS/CONICA (H and K) and the ISAAC (L and M) instruments. The large field of view (70" x 70") of the ISAAC instrument and the large number of sources identified (L-M data for 541 sources) allows us to investigate colors, infrared excesses and extended dust emission. Our new L-band magnitude calibration reveals an offset to the traditionally used calibrations, which we attribute to the use of the variable star IRS7 as a flux calibrator. Together with new results on the extinction towards the Galactic Center (Scoville et al. 2003; Raab 2000), our magnitude calibration results in stellar color properties expected from standard stars and removes any necessity to modify the K-band extinction. The large number of sources for which we have obtained L-M colors allows us to measure the M-band extinction to A_M=(0.056+-0.006)A_V (approximately =A_L), a considerably high...

    Full Text Available Small business is the backbone of the U.S. economy; when the financial literacy skills of entrepreneurs fall short of those needed to operate a successful business, it is more than the individual business at risk. In 2012, 14 small businesses requesting growth-acceleration consulting services from the Florida Small Business Development Center at the University of South Florida were assessed financially as part of the service provided by the Center. Financial ratios were used to analyze the business’s financial condition. While performing the financial analysis of these firms, we also surveyed the business owners to determine their level of financial understanding and their use of financial statements in making management decisions. We found a strong association between the small businesses' financial strength and the business owners’ habits of mind with regard to their financial statements: for 7/14 of the businesses, the business owner did not regularly review financial statements, and 6/7 of those businesses were experiencing financial difficulties; conversely, 7/14 of the businesses in the study were experiencing financial difficulties, and for 6/7 of them, the business owner did not regularly review the financial statements.

    1978-01-01

    Data from the SAS-3 satellite were used in a search for X-ray pulsations from the direction of the galactic center. No periodic X-ray behavior was detected in the frequency interval 0.6 Hz to 0.0006 Hz and energy range 2.5 - 35 keV. For periods less than 60 sec, the upper limit to the amplitude of any pulsation in the 2.5 - 10 keV band is approximately .0017 cts/sq cm/s. This corresponds to a pulsed fraction of approximately 1.3 percent of the total GCX flux. Somewhat higher limits apply for longer periods and for energies greater than 10 keV.

    We present a catalog of 9017 X-ray sources identified in Chandra observations of a 2 by 0.8 degree field around the Galactic center. We increase the number of known X-ray sources in the region by a factor of 2.5. The catalog incorporates all of the ACIS-I observations as of 2007 August, which total 2.25 Msec of exposure. At the distance to the Galactic center (8 kpc), we are sensitive to sources with luminosities >4e32 erg/s (0.5-8.0 keV; 90% confidence) over an area of one square degree, and up to an order of magnitude more sensitive in the deepest exposure (1.0 Msec) around Sgr A*. The positions of 60% of our sources are accurate to <1" (95% confidence), and 20% have positions accurate to <0.5". We search for variable sources, and find that 3% exhibit flux variations within an observation, 10% exhibit variations from observation-to-observation. We also find one source, CXOUGC J174622.7-285218, with a periodic 1745 s signal (1.4% chance probability), which is probably a magnetically-accreting cataclysm...

  2. Audit of a Scientific Data Center for Certification as a Trustworthy Digital Repository: A Case Study

    Downs, R. R.; Chen, R. S.

    2011-12-01

    Services that preserve and enable future access to scientific data are necessary to ensure that the data that are being collected today will be available for use by future generations of scientists. Many data centers, archives, and other digital repositories are working to improve their ability to serve as long-term stewards of scientific data. Trust in sustainable data management and preservation capabilities of digital repositories can influence decisions to use these services to deposit or obtain scientific data. Building on the Open Archival Information System (OAIS) Reference Model developed by the Consultative Committee for Space Data Systems (CCSDS) and adopted by the International Organization for Standardization as ISO 14721:2003, new standards are being developed to improve long-term data management processes and documentation. The Draft Information Standard ISO/DIS 16363, "Space data and information transfer systems - Audit and certification of trustworthy digital repositories" offers the potential to evaluate digital repositories objectively in terms of their trustworthiness as long-term stewards of digital resources. In conjunction with this, the CCSDS and ISO are developing another draft standard for the auditing and certification process, ISO/DIS 16919, "Space data and information transfer systems - Requirements for bodies providing audit and certification of candidate trustworthy digital repositories". Six test audits were conducted of scientific data centers and archives in Europe and the United States to test the use of these draft standards and identify potential improvements for the standards and for the participating digital repositories. We present a case study of the test audit conducted on the NASA Socioeconomic Data and Applications Center (SEDAC) and describe the preparation, the audit process, recommendations received, and next steps to obtain certification as a trustworthy digital repository, after approval of the ISO/DIS standards.

  3. Analysis of the Service Quality of Medical Centers Using Servqual Model (Case:Shaheed Rahnemoon Hospital

    H Zare Ahmadabadi

    2007-07-01

    Full Text Available Introduction: Many organizations, especially service oriented ones, relative to their goals and mission, have a special view towards quality phenomena and its management. Methods: This paper analyzes medical service quality in one case; The internal section of Shaheed Rahnemoon Hospital Based on the basis of gap analysis model and Servqual technique. A questionnaire was designed and applied to measure expectations and perceptions of patients and personnel of the hospital. Results: On application of non-parametric statistical tests, we propose certain recommendations. These tests drive on five conceptual dimensions of service quality including intangibility, responsiveness, reliability, assurance and empathy. Results show that patients in this section were satisfied from the service provider’s responsiveness, but there are significant differences between expectations and perceptions in other dimensions. Conclusion: The service quality analysis models are useful for managers of medical centers to distinguish gaps between the two sides of service representation; patients and medical centers personnel. Ultimately, they can reinforce strengths and control weaknesses.

  4. Three-body scattering problem in the fixed center approximation: the case of attraction

    CERN Document Server

    Kudryavtsev, Alexander E; Romanov, Alexander I

    2016-01-01

    We study scattering of a light particle on a bound pair of heavy particles (e.g., the deuteron) within the fixed center approximation in the case of light-heavy attraction, solving the integral equation for the three-body Green's function both in the coordinate and in the momentum space. The results for the three-body scattering amplitude appear to be ambiguous -- they depend on a single real parameter. This parameter may be fixed by a three-body input, e.g., the three-body scattering length. We also solve the integral equation for the three-body Green function in the momentum space, introducing a finite cut-off. We show that all three approaches are equivalent. We also discuss how our approach to the problem matches with the introduction of three-body contact interaction as done by other authors.

    Childhood-onset cluster headache is an excruciatingly painful and distressing condition. A retrospective study was conducted on charts of patients referring to our Headache Center. Those diagnosed as cluster headache were selected. We identified 11 children (6 males and 5 females). The mean age of cluster headache onset was 10 years (range: 5-16). All children had episodic cluster headache. All children had unilateral orbital pain; 7 patients had throbbing pain, whereas 4 children complained stabbing pain. The mean duration of the attack was 86 minutes (ranging from 30 to 180 minutes). The frequency of episodes was between 1 and 4 per day. All children had the typical cluster headache autonomic features, such as lacrimation, conjunctival injection, ptosis, and nostril rhinorrhea. Steroids showed a good clinical efficacy in interrupting cluster headache recurrence. As symptomatic drugs, acetaminophen as well as ibuprofen were ineffective; indomethacin was effective in 1 case.

    2010-01-01

    Full Text Available Lyme neuroborreliosis or “neurological Lyme disease” was evidenced in 2 of 23 patients submitted to strict criteria for case selection of the Centers for Disease Control and Prevention employing a two-tier test to detect antibodies to Borrelia burgdorferi at a single institution. One patient had symptomatic polyradiculoneuritis, dysautonomia, and serological evidence of early infection; and another had symptomatic small fiber sensory neuropathy, distal polyneuropathy, dysautonomia, and serological evidence of late infection. In the remaining patients symptoms initially ascribed to Lyme disease were probably unrelated to B. burgdorferi infection. Our findings suggest early susceptibility and protracted involvement of the nervous system most likely due to the immunological effects of B. burgdorferi infection, although the exact mechanisms remain uncertain.

    Law, C

    2004-01-01

    We report the first detection of X-ray emission from the Quintuplet star cluster and compare its X-ray emission to that of the Arches star cluster. Four point sources are significantly detected near the core of the Quintuplet cluster with a total, absorption-corrected luminosity of ~1\\times10^{33} ergs s^{-1}. Diffuse, thermal emission is also detected near the core of the Quintuplet cluster with an absorption-corrected luminosity of ~1\\times10^{34} ergs s^{-1}. We analyze the diffuse and point-like emission from the Arches and Quintuplet and discuss the possibility that they are host to cluster wind outflows. We also present the results of our search for X-ray emission from candidate star clusters in the Galactic center (GC) region. We use extinction estimated by near-IR colors and X-ray spectral fits, as well as other IR properties, to determine if the candidate clusters are new, GC star clusters. We find that three of the six candidate clusters found toward the GC are likely foreground clusters, two of the...

    2007-01-01

    We present Spitzer IRS spectra (R ~600, 10 - 38 micron) of 38 positions in the Galactic Center (GC), all at the same Galactic longitude and spanning plus/minus 0.3 degrees in latitude. Our positions include the Arches Cluster, the Arched Filaments, regions near the Quintuplet Cluster, the ``Bubble'' lying along the same line-of-sight as the molecular cloud G0.11-0.11, and the diffuse interstellar gas along the line-of-sight at higher Galactic latitudes. From measurements of the [O IV], [Ne II], [Ne III], [Si II], [S III], [S IV], [Fe II], [Fe III], and H_2 S(0), S(1), and S(2) lines we determine the gas excitation and ionic abundance ratios. The Ne/H and S/H abundance ratios are ~ 1.6 times that of the Orion Nebula. The main source of excitation is photoionization, with the Arches Cluster ionizing the Arched Filaments and the Quintuplet Cluster ionizing the gas nearby and at lower Galactic latitudes including the far side of the Bubble. In addition, strong shocks ionize gas to O^{+3} and destroy dust grains, ...

    Fukui et al. (2006) discovered two molecular loops in the Galactic center that are likely created by the magnetic flotation due to the Parker instability. Following the discovery, we present here a detailed study of the two loops based on NANTEN 12CO(J=1-0) and 13CO(J=1-0) datasets. The two loops are located in (l, b) ~ (357, 1) deg. at a velocity range of -20 - -180 km/s with a projected total length of ~ 600 pc and heights of ~250 - 300 pc from the Galactic disk at a distance of 8.5 kpc. They show bright foot points in the 12CO emission in the edges of the loops at b ~ 0.8 - 1.0 deg.. These foot points are characterized by velocity dispersions of 50 - 100 km/s. The loops also show large-scale velocity gradients of ~30 - 50 km/s per ~100 pc. The loops also have counterparts of the HI gas and IRAS emissions. The HI gas with weaker intensity fills the inner part of the loops where there is no significant 12CO and 13CO emission. We estimate total mass and kinetic energy of the loops are ~1.5 - 2.5 x 10^6 Msun a...

    Part I of this series discussed our observations of Ground Zero of the World Trade Center (WTC) immediately after the attack on September 11, 2001, as well as the stress-response of police officers on site. This paper offers a variety of clinical techniques for emergency mental health practitioners and first responders for use with victims of critical incidents. The suggested interventions are based on the theory and clinical practice of Emergency Medical Hypnosis, Neuro-Linguistic Programming, and Ericksonian Psychotherapy. Specific examples of how they were applied with police personnel following the World Trade Center attack are provided along with specific clinical guidelines. These interventions are designed to augment and enhance standard CISM, mental health, and medical practice in the field. PMID:12166017

  12. Observational evidences for the existence of 17.4 keV decaying degenerate sterile neutrinos near the Galactic Center

    CERN Document Server

    Chan, Man Ho

    2010-01-01

    We show that the existence of a degenerate halo of sterile neutrinos with rest mass of 17.4 keV near the Galactic Center can account for both the excess 8.7 keV emission observed by the $Suzaku$ mission and the power needed ($10^{40}$ erg s$^{-1}$) to maintain the high temperature of the hot gas (8 keV) near the Galactic Center. The required decay rate and mixing angle of the sterile neutrinos are $\\Gamma \\ge 5 \\times 10^{-20}$ s$^{-1}$ and $\\sin^22 \\theta \\sim 10^{-3}-10^{-4}$ respectively. These values are consistent with a low reheating temperature in the inflation model, and suggest the exciting possibility that the sterile - active neutrino oscillation can be visible in near future experiments.

This analysis introduces flexible statistical methods for estimating center-level effects on individual outcomes in the context of highly variable patient populations, such as those of the PRospective, Observational, Multi-center Major Trauma Transfusion study. Ten US level I trauma centers enrolled a total of 1,245 trauma patients who survived at least 30 minutes after admission and received at least one unit of red blood cells. Outcomes included death, multiple organ failure, substantial bleeding, and transfusion of blood products. The centers involved were classified as either large or small-volume based on the number of massive transfusion patients enrolled during the study period. We focused on estimation of parameters inspired by causal inference, specifically estimated impacts on patient outcomes related to the volume of the trauma hospital that treated them. We defined this association as the change in mean outcomes of interest that would be observed if, contrary to fact, subjects from large-volume sites were treated at small-volume sites (the effect of treatment among the treated. We estimated this parameter using three different methods, some of which use data-adaptive machine learning tools to derive the outcome models, minimizing residual confounding by reducing model misspecification. Differences between unadjusted and adjusted estimators sometimes differed dramatically, demonstrating the need to account for differences in patient characteristics in clinic comparisons. In addition, the estimators based on robust adjustment methods showed potential impacts of hospital volume. For instance, we estimated a survival benefit for patients who were treated at large-volume sites, which was not apparent in simpler, unadjusted comparisons. By removing arbitrary modeling decisions from the estimation process and concentrating

    To evaluate the efficacy of engineering controls in reducing worker exposure to metalworking fluids, an evaluation of an enclosure for a machining center during face milling was performed. The enclosure was built around a vertical metal machining center with an attached ventilation system consisting of a 25-cm diameter duct, a fan, and an air-cleaning filter. The evaluation method included using sulfur hexafluoride (SF6) tracer gas to determine the ventilation system's flow rate and capture efficiency, a respirable aerosol monitor (RAM) to identify aerosol leak locations around the enclosure, and smoke tubes and a velometer to evaluate air movement around the outside of the enclosure. Results of the tracer gas evaluation indicated that the control system was approximately 98% efficient at capturing tracer gas released near the spindle of the machining center. This result was not significantly different from 100% efficiency (p = 0.2). The measured SF6 concentration when released directly into the duct had a relative standard deviation of 2.2%; whereas, when releasing SF6 at the spindle, the concentration had a significantly higher relative standard deviation of 7.8% (p = 0.016). This increased variability could be due to a cyclic leakage at a small gap between the upper and lower portion of the enclosure or due to cyclic stagnation. Leakage also was observed with smoke tubes, a velometer, and an aerosol photometer. The tool and fluid motion combined to induce a periodic airflow in and out of the enclosure. These results suggest that tracer gas methods could be used to evaluate enclosure efficiency. However, smoke tubes and aerosol instrumentation such as optical particle counters or aerosol photometers also need to be used to locate leakage from enclosures. PMID:10635544

    Full Text Available In this paper, we address the topic of user-centered design (UCD for cartography, GIScience, and visual analytics. Interactive maps are ubiquitous in modern society, yet they often fail to “work” as they could or should. UCD describes the process of ensuring interface success—map-based or otherwise—by gathering input and feedback from target users throughout the design and development of the interface. We contribute to the expanding literature on UCD for interactive maps in two ways. First, we synthesize core concepts on UCD from cartography and related fields, as well as offer new ideas, in order to organize existing frameworks and recommendations regarding the UCD of interactive maps. Second, we report on a case study UCD process for GeoVISTA CrimeViz, an interactive and web-based mapping application supporting visual analytics of criminal activity in space and time. The GeoVISTA CrimeViz concept and interface were improved iteratively by working through a series of user→utility→usability loops in which target users provided input and feedback on needs and designs (user, prompting revisions to the conceptualization and functional requirements of the interface (utility, and ultimately leading to new mockups and prototypes of the interface (usability for additional evaluation by target users (user… and so on. Together, the background review and case study offer guidance for applying UCD to interactive mapping projects, and demonstrate the benefit of including target users throughout design and development.

    Full Text Available Background: Neoplastic meningitis (NM is a condition characterized by leptomeningeal involvement by metastatic carcinoma. Detection of exfoliated malignant cells in cerebrospinal fluid (CSF due to meningeal metastasis is frequently associated with diverse neurologic presentations. Materials and Methods: In this retrospective study of all cases of NM diagnosed in CSF samples over a 20-year period at a tertiary care referral center, the cytomorphologic features were reviewed. Results: Sixty six cases of NM were identified of which 36 already had an established diagnosis of malignancy while in 30 patients, there was no previously known tumor. The most common known primary in the former group was breast followed by ovary. Single cell pattern, cellular cannibalism, moderate cytoplasm and rounded nuclei were seen in breast and lung tumors. Papillary architecture and cytoplasmic vacuolation were seen in the ovarian primaries. Melanin pigment was seen in malignant melanoma. Conclusion: CSF cytology is an important tool for diagnosis of NM. Cytomorphologic features helped in diagnosis and for prediction of the primary site. Correct identification of this condition is important as it has therapeutic and prognostic implications.

  19. Personality traits affect teaching performance of attending physicians: results of a multi-center observational study.

    Directory of Open Access Journals (Sweden)

    Renée A Scheepers

    Full Text Available BACKGROUND: Worldwide, attending physicians train residents to become competent providers of patient care. To assess adequate training, attending physicians are increasingly evaluated on their teaching performance. Research suggests that personality traits affect teaching performance, consistent with studied effects of personality traits on job performance and academic performance in medicine. However, up till date, research in clinical teaching practice did not use quantitative methods and did not account for specialty differences. We empirically studied the relationship of attending physicians' personality traits with their teaching performance across surgical and non-surgical specialties. METHOD: We conducted a survey across surgical and non-surgical specialties in eighteen medical centers in the Netherlands. Residents evaluated attending physicians' overall teaching performance, as well as the specific domains learning climate, professional attitude, communication, evaluation, and feedback, using the validated 21-item System for Evaluation of Teaching Qualities (SETQ. Attending physicians self-evaluated their personality traits on a 5-point scale using the validated 10-item Big Five Inventory (BFI, yielding the Five Factor model: extraversion, conscientiousness, neuroticism, agreeableness and openness. RESULTS: Overall, 622 (77% attending physicians and 549 (68% residents participated. Extraversion positively related to overall teaching performance (regression coefficient, B: 0.05, 95% CI: 0.01 to 0.10, P = 0.02. Openness was negatively associated with scores on feedback for surgical specialties only (B: -0.10, 95% CI: -0.15 to -0.05, P<0.001 and conscientiousness was positively related to evaluation of residents for non-surgical specialties only (B: 0.13, 95% CI: 0.03 to 0.22, p = 0.01. CONCLUSIONS: Extraverted attending physicians were consistently evaluated as better supervisors. Surgical attending physicians who display high levels of

    International Nuclear Information System (INIS)

    Complete text of publication follows. Near-bottom magnetic measurements provide us high-resolution magnetic anomaly. The high-resolution anomaly is valuable for the studies of the detailed magnetization structure of ocean crust and paleointensity recorded on the ocean crust. We visited the Mariana Trough in the western Pacific to dive in the 17 deg N segment with the Japanese submersible Shinkai 6500 in June - July 2008. Objectives of the submersible survey were: 1) observation of lava flow morphology, faults, and fissures and their spatial variation, 2) collection of rock and sediment samples for chemical and age analysis, and 3) geophysical measurements using a deep-sea magnetometer and a sub-bottom profiler to investigate magnetization of the lava flow and thickness of sedimentary layers that cover the lavas. Because the magnetization intensities relate to age of lava, deep-sea magnetic data may provide geophysical evidence for discussion of old and new lava flows. Quantifiable degrees of sedimentation superposed on the lavas suggest relative age differences of formation. In this paper we focus on our visual geological observation and the spatial and temporal variations of the magnetization of the ocean crust.

  4. Observation of antideuteron production in electron-positron annihilation at 10 GeV center of mass energy

    International Nuclear Information System (INIS)

    The production of antideuterons has been observed in electron-positron annihilations at center-of-mass energies around 10 GeV. Antideuterons have been identified unambiguously by their energy loss in the drift chamber, their time-of-flight and the pattern of their energy deposition in the shower counters of the ARGUS detector. The production rate in the momentum range (0.6-1.8)GeV/c is (1.6sub(-0.7)sup(+1.0))) X 10-5 per hadronic event. (orig.)

  5. Human-centered modeling in human reliability analysis: some trends based on case studies

    International Nuclear Information System (INIS)

    As an informal working group of researchers from France, Germany and The Netherlands created in 1993, the EARTH association is investigating significant subjects in the field of human reliability analysis (HRA). Our initial review of cases from nuclear operating experience showed that decision-based unrequired actions (DUA) contribute to risk significantly on the one hand. On the other hand, our evaluation of current HRA methods showed that these methods do not cover such actions adequately. Especially, practice-oriented guidelines for their predictive identification are lacking. We assumed that a basic cause for such difficulties was that these methods actually use a limited representation of the stimulus-organism-response (SOR) paradigm. We proposed a human-centered model, which better highlights the active role of the operators and the importance of their culture, attitudes and goals. This orientation was encouraged by our review of current HRA research activities. We therefore decided to envisage progress by identifying cognitive tendencies in the context of operating and simulator experience. For this purpose, advanced approaches for retrospective event analysis were discussed. Some orientations for improvements were proposed. By analyzing cases, various cognitive tendencies were identified, together with useful information about their context. Some of them match psychological findings already published in the literature, some of them are not covered adequately by the literature that we reviewed. Finally, this exploratory study shows that contextual and case-illustrated findings about cognitive tendencies provide useful help for the predictive identification of DUA in HRA. More research should be carried out to complement our findings and elaborate more detailed and systematic guidelines for using them in HRA studies

    Context. The compact radio and near-infrared (NIR) source Sagittarius A* (Sgr A*) associated with the supermassive black hole in the Galactic center was observed at 7 mm in the context of a NIR triggered global Very Long Baseline Array (VLBA) campaign. Aims. Sgr A* shows variable flux densities ranging from radio through X-rays. These variations sometimes appear in spontaneous outbursts that are referred to as flares. Multi-frequency observations of Sgr A* provide access to easily observable parameters that can test the currently accepted models that try to explain these intensity outbursts. Methods. On May 16-18, 2012 Sgr A* has been observed with the VLBA at 7 mm (43 GHz) for 6 hours each day during a global multi-wavelength campaign. These observations were triggered by a NIR flare observed at the Very Large Telescope (VLT). Accurate flux densities and source morphologies were acquired. Results. The total 7 mm flux of Sgr A* shows only minor variations during its quiescent states on a daily basis of 0.06 J...

    We present radio images within 30$''$ of Sgr A* based on recent VLA observations at 34 GHz with 7.8 microJy sensitivity and resolution $\\sim88\\times46$ milliarcseconds (mas). We report 44 partially resolved compact sources clustered in two regions in the E arm of ionized gas that orbits Sgr A*. These sources have size scales ranging between ~50 and 200 mas (400 to 1600 AUs), and a bow-shock appearance facing the direction of Sgr A*. Unlike the bow-shock sources previously identified in the near-IR but associated with massive stars, these 34 GHz sources do not appear to have near-IR counterparts at 3.8 $\\mu$m. We interpret these sources as a candidate population of photoevaporative protoplanetary disks (proplyds) that are associated with newly formed low mass stars with mass loss rates ~10^{-7} - 10^{-6} solar mass per year and are located at the edge of a molecular cloud outlined by ionized gas. The disks are externally illuminated by strong Lyman continuum radiation from the ~100 OB and WR massive stars dist...

    Galaxy observations and N-body cosmological simulations produce conflicting dark matter halo density profiles for galaxy central regions. While simulations suggest a cuspy and universal profile (UDP) of this region, the majority of observations favor variable profiles with a core in the center. In this paper, we investigate the convergency of standard N-body simulations, especially in the cusp region, following the approach proposed by (Baushev, 2015). We simulate the well known Hernquist model using the SPH code Gadget-3 and consider the full array of dynamical parameters of the particles. We find that, although the cuspy profile is stable, all integrals of motion characterizing individual particles suffer strong unphysical variations along the whole halo, revealing an effective interaction between the test bodies. This result casts doubts on the reliability of the velocity distribution function obtained in the simulations. Moreover, we find unphysical Fokker-Planck streams of particles in the cusp region.

    Full Text Available Information centers are duly obliged to move in line with their parent organizations’ goals and missions in creating knowledge. In the age of information and communication revolution, and in a knowledge-based economy, organizations that are involved in creation of knowledge have an important role in communication and diffusion of knowledge. In the mean time, libraries and information centers change from being mere depository sources to knowledge institutions. The current research aimed to study the present state of knowledge management infrastructures of the Regional Information Center for Science and Technology (RICeST as a national and regional information center. The statistic population of this study was consisted of 87 staff. Data was collected by means of questionnaires, observation and interviews. The results showed the required infrastructure for KM activities were almost there, among different aspects of which, budgeting had a better situation in the institution under study. In regards with establishment of knowledge management, RICeST was paying more attention to information and communication technology and knowledge network via applications such as the Internet and extranets. Another fact was that in the RICeST, emphasis was on learning and on human resources as the substantial sources in creation of knowledge. Among other aspects, “organizational culture” was in a lower state compared with other aspects in the RICeST.

These observations were triggered by a NIR flare observed at the Very Large Telescope (VLT). Accurate flux densities and source morphologies were acquired. Results: The total 7 mm flux of Sgr A* shows only minor variations during its quiescent states on a daily basis of 0.06 Jy. An observed NIR flare on May 17 was followed ~4.5 h later by an increase in flux density of 0.22 Jy at 43 GHz. This agrees well with the expected time delay of events that are casually connected by adiabatic expansion. Shortly before the peak of the radio flare, Sgr A* developed a secondary radio off-core feature at 1.5 mas toward the southeast. Even though the closure phases are too noisy to place actual constraints on this feature, a component at this scale together with a time delay of 4.5 ± 0.5 h between the NIR and radio flare provide evidence for an adiabatically expanding jet feature.

    We report on multi-frequency, wideband radio observations of the Galactic Center magnetar (SGR 1745$-$2900) with the Green Bank Telescope for $\\sim$100 days immediately following its initial X-ray outburst in April 2013. We made multiple simultaneous observations at 1.5, 2.0, and 8.9 GHz, allowing us to examine the magnetar's flux evolution, radio spectrum, and interstellar medium parameters (such as the dispersion measure (DM), the scattering timescale and its index). During two epochs, we have simultaneous observations from the Chandra X-ray Observatory, which permitted the absolute alignment of the radio and X-ray profiles. As with the two other radio magnetars with published alignments, the radio profile lies within the broad peak of the X-ray profile, preceding the X-ray profile maximum by $\\sim$0.2 rotations. We also find that the radio spectral index $\\gamma$ is significantly negative between $\\sim$2 and 9 GHz; during the final $\\sim$30 days of our observations $\\gamma \\sim -1.4$, which is typical of c...

    1994-12-13

    We have used spectrally photoselective femtosecond transient absorption spectroscopy on photosystem II reaction centers to show that there are at least two pools of chlorin molecules/states which can transfer excitation energy to P680, the primary electron donor in photosystem II. It has previously been shown that one chlorin pool equilibrates with P680 in 100 fs [Durrant et al. (1992) Proc. Natl. Acad. Sci. U.S.A. 89, 11632-11636], and we report here the observation of energy transfer from a second more weakly coupled chlorin pool. The effect of the weakly coupled pool is to increase the apparent time constant for radical pair formation from 21 ps when P680 is selectively excited to 27 ps when the accessory chlorins are excited. We conclude that it is possible to observe both radical pair formation somewhat slowed by an energy transfer step and radical pair formation not limited by this slow energy transfer, depending upon which chromophores are initially excited. These observations provide evidence that when using photoselective excitation of P680, the observed 21 ps time constant for radical pair formation is not limited by a slow energy transfer step.

    2015-04-01

    Full Text Available Vertex and p-center problems are two well-known types of the center problem. In this paper, a p-center problem with uncertain demand-weighted distance will be introduced in which the demands are considered as fuzzy random variables (FRVs and the objective of the problem is to minimize the maximum distance between a node and its nearest facility. Then, by introducing new methods, the proposed problem is converted to deterministic integer programming (IP problems where these methods will be obtained through the implementation of the possibility theory and fuzzy random chance-constrained programming (FRCCP. Finally, the proposed methods are applied for locating bicycle stations in the city of Tabriz in Iran as a real case study. The computational results of our study show that these methods can be implemented for the center problem with uncertain frameworks.

    Full Text Available AIM: To evaluate the safety to donors of living-donor liver transplantation. METHODS: This study included 300 consecutive living liver tissue donors who underwent operations at our center from July 2002 to December 2012. We evaluated the safety of donors with regard to three aspects complications were recorded prospectively and stratified by grade according to Clavien's classification, and the data were compared in two stages (the first 5 years' experience (pre-January 2008 and the latter 5 years' experience (post-January 2008; laboratory tests such as liver function and blood biochemistry were performed; and the health-related quality of life was evaluated. RESULTS: There was no donor mortality at our center, and the overall morbidity rate was 25.3%. Most of the complications of living donors were either grade I or II. There were significantly fewer complications in the latter period of our study than in the initial period (19.9% vs 32.6%, P<0.001, and biliary complications were the most common complications, with an incidence of 9%. All of the liver dysfunction was temporary; however, the post-operative suppression of platelet count lasted for years. Although within the normal range, eight years after operation, 22 donors showed lower platelet levels (189 × 10(9/L compared with the pre-operative levels (267 × 10(9/L (P<0.05. A total of 98.4% of donors had returned to their previous levels of social activity and work, and 99.2% of donors would donate again if it was required and feasible. With the exception of two donors who experienced grade III complications (whose recipients died and a few cases of abdominal discomfort, fatigue, chronic pain and scar itching, none of the living donors were affected by physical problems. CONCLUSION: With careful donor selection and specialized patient care, low morbidity rates and satisfactory long-term recovery can be achieved after hepatectomy for living-donor liver transplantation.

    Full Text Available The goal of this paper is to review the validity of seismic assessment procedure given in the Turkish Earthquake Code by comparing the assessment results with real structures from Eastern Turkey, where the 2011 Van earthquake occurred. To test the analysis methods for a typically suitable structure, the cultural center building at Erciş with 3 stories, is selected. In order to compare the results of the three different analysis techniques, for an identical earthquake, the ground motion used in analysis was characterized by equivalent elastic earthquake spectra, which were developed from available time history at the nearest construction site. It was found that the damage predictions by using the by Turkish Earthquake Code procedures point out the different level of damages. But, it is concluded that nonlinear time history analysis calculated the best estimation of the damage observed in the site.

  5. Observational Evidences for the Existence of 17.4 keV Decaying Degenerate Sterile Neutrinos Near the Galactic Center

    Chan, M. H.; Chu, M.-C.

    2011-02-01

    We show that the existence of a degenerate halo of sterile neutrinos with rest mass of 17.4 keV near the Galactic center (GC) can account for both the excess 8.7 keV emission observed by the Suzaku mission and the power needed (1040 erg s-1) to maintain the high temperature of the hot gas (8 keV) near the GC. The required decay rate and mixing angle of the sterile neutrinos are Γ >= 10-19 s-1 and sin22θ ~ 10-3, respectively. These values are consistent with a low reheating temperature, which suppresses the production of sterile neutrinos, resulting in a small sterile neutrino density parameter (Ω s sterile-active neutrino oscillation may be visible in near future experiments.

    Clinical vignettes from the World Trade Center Worker and Volunteer Mental Health Monitoring and Treatment Program at the Mount Sinai Medical Center in New York City are presented. The hospital-based program pairs mental health screenings with federally funded occupational medical screenings to identify persons with mental health problems related to their rescue and recovery roles. The program also provides on-site mental health treatment. The cases illustrate the diverse mental health needs of the rescue and recovery workers, some of whom initially sought treatment years after September 11, 2001. The cases show that in addition to symptoms of posttraumatic stress disorder, workers experienced survivor guilt, distressing memories of childhood trauma, shame associated with intense feelings, substance abuse relapse, psychosis, and problems with family relationships.

    The purpose of this study was to investigate risk factors that are associated with heterotopic pregnancy (HP) following in vitro fertilization (IVF)-embryo transfer (ET) and to demonstrate the outcomes of HP after the surgical treatment of ectopic pregnancies. Forty-eight patients from a single center, who were diagnosed with HP between 1998 and 2012 were included. All of the patients had received infertility treatments, such as Clomid with timed coitus (n = 1, 2.1%), superovulation with intrauterine insemination (n = 7, 14.6%), fresh non-donor IVF-ET (n = 33, 68.8%), and frozen-thawed cycles (n = 7, 14.6%). Eighty-four additional patients were randomly selected as controls from the IVF registry database. HP was diagnosed at 7.5 ± 1.2 weeks (range 5.4-10.3) gestational age. In six cases (12.5%), the diagnosis was made three weeks after the patients underwent treatment for abortion. There were significant differences in the history of ectopic pregnancy (22.5% vs. 3.6%, P = 0.002). There were no significant differences in either group between the rates of first trimester intrauterine fetal loss (15.0% vs. 13.1%) or live birth (80.0% vs. 84.1%) after the surgical treatment for ectopic pregnancy. The risk factors for HP include a history of ectopic pregnancy (OR 7.191 [1.591-32.513], P = 0.010), abortion (OR 3.948 [1.574-9.902], P = 0.003), and ovarian hyperstimulation syndrome (OHSS) (OR 10.773 [2.415-48.060], P = 0.002). In patients undergoing IVF-ET, history of ectopic pregnancy, abortion, and OHSS may be risk factors for HP as compared to the control group of other IVF patients. The surgical treatment of HP does not appear to affect the rates of first trimester fetal loss or live birth. PMID:27366008

    various activities and lessons while at the center, and the assessment of the student's learning following the experience. The staff works with each teacher to prepare them to use transdisciplinary science lessons which were planned to satisfy and enrich state, district, and school expectations (Outdoor Education Guidebook, 1997). The staff members believe that if the teachers are prepared to do these things, not only will the current students learn more, but that the teacher will experience growth professionally and this will impact more children over time. The teachers gain science content knowledge and learn constructivist teaching strategies while learning how to use the facilities and equipment safely and confidently. Ideas for preparatory and follow-up activities are made available. This study looked closely at the individualization of the professional development provided by this informal science institution. Data from observations of professional development sessions as well as the on-site experiences with the children were used in the study. Teachers were asked to reflect on the degree to which the Arlington Echo approach to professional development was beneficial in building their confidence about providing science-based, interdisciplinary experiences for their students, with comparisons made between the responses of veteran teachers and those of teachers with fewer years of experience. Through the reflections of the participant teachers, it was possible to gather data about whether their beliefs about science and about how science is best taught were modified by this experience.

    The National Science Foundation (NSF) provides the National Center for Atmospheric Research (NCAR) Earth Observing Laboratory (EOL) funding for the operation, maintenance and upgrade of two research aircraft: the NSF/NCAR High-performance Instrumented Airborne Platform for Environmental Research (HIAPER) Gulfstream V and the NSF/NCAR Hercules C-130. A suite of in-situ and remote sensing airborne instruments housed at the EOL Research Aviation Facility (RAF) provide a basic set of measurements that are typically deployed on most airborne field campaigns. In addition, instruments to address more specific research requirements are provided by collaborating participants from universities, industry, NASA, NOAA or other agencies (referred to as Principal Investigator, or PI, instruments). At the 2014 AGU Fall Meeting, a poster (IN13B-3639) was presented outlining the components of Airborne Data Management included field phase data collection, formats, data archival and documentation, version control, storage practices, stewardship and obsolete data formats, and public data access. This talk will cover lessons learned, challenges associated with the above components, and current developments to address these challenges, including: tracking data workflows for aircraft instrumentation to facilitate identification, and correction, of gaps in these workflows; implementation of dataset versioning guidelines; and assignment of Digital Object Identifiers (DOIs) to data and instrumentation to facilitate tracking data and facility use in publications.

    Cluster observations of large amplitude solitary waves (up to ~250 mV/m), identified as electron holes, were studied for six days when the satellites repeatedly crossed the plasma sheet near a reconnection region. Examination of EFW instrument burst data, with an automated program [Dombeck et al., 2001] and visual inspection, detected solitary waves on 18 of the 24 bursts. There was one 10 second burst on each spacecraft each day with solitary waves detected in at least one burst from every day. Solitary waves were seen on all four spacecraft during three of the days. The variety of positions surveyed by Cluster due to both spacecraft separation and the differing locations with respect to the reconnection region at each of the six events enables a comparison of solitary wave duration and peak to peak electric field in many different parts of the reconnection region. The study expands work by Cattell et al. [2005] which, along with simulations by Drake et al. [2003], showed that electron holes could provide some of the particle scattering needed in the reconnection process. The August 24, 2003 burst on spacecraft 2 is unique because several solitary waves were detected less than 200 km from and some within a few km of the center of the current sheet (BXgse=0). This is in contrast to the Cattell et al. [2005] results where solitary waves were only seen on spacecraft greater than 1,500 km from the center of the current sheet. Peak to peak electric fields of a few to hundreds of mV/m and durations of tenths to tens of microseconds were consistent for solitary waves both near and far from the center of the current sheet. In agreement with previous studies and independent of position in the current sheet, all solitary waves were detected during times when PEACE measured narrow field aligned electron beams. While recent studies, such as Che et al. [2009] and Goldman et al. [2008], suggested different wave modes for the evolution of solitary waves, a determination of

    AIM: To identify the clinical features and outcomes of infrequently reported leptomeningeal carcinomatosis (LMC) of gastric cancer.METHODS: We analyzed 54 cases of cytologically con- firmed gastric LMC at four institutions from 1994 to 2007.RESULTS: The male-to-female ratio was 32:22, and the patients ranged in age from 28 to 78 years (median,48.5 years). The majority of patients had advanced disease at initial diagnosis of gastric cancer. The clinical or pathologic tumor, node and metastasis stage of the primary gastric cancer was Ⅳ in 38 patients (70%).The median interval from diagnosis of the primary malignancy to the diagnosis of LMC was 6.3 mo, ranging between 0 and 73.1 mo. Of the initial endoscopic findings for the 45 available patients, 23 (51%) of the patients were Bormann type Ⅲ and 15 (33%) patients were Bormann type Ⅳ. Pathologically, 94% of cases proved to be poorly differentiated adenocarcinomas.Signet ring cell component was also observed in 40% of patients. Headache (85%) and nausea/vomiting (58%) were the most common presenting symptoms of LMC. A gadolinium-enhanced magnetic resonance imaging was conducted in 51 patients. Leptomeningeal enhancement was noted in 45 cases (82%). Intrathecal (IT) chemotherapy was administered to 36 patientsprimarily methotrexate alone (61%), but also in combination with hydrocortisone/± Ara-C (39%). The median number of IT treatments was 7 (range, 1-18). Concomitant radiotherapy was administered to 18 patients,and concomitant chemotherapy to seven patients. Seventeen patients (46%) achieved cytological negative conversion. Median overall survival duration from the diagnosis of LMC was 6.7 wk (95% CI: 4.3-9.1 wk). In the univariate analysis of survival duration, hemoglobin,IT chemotherapy, and cytological negative conversion showed superior survival duration ( P = 0.038, P = 0.010, and P = 0.002, respectively). However, in our multivariate analysis, only cytological negative conversion was predictive of

    2007-12-01

    Emmons Lake Volcanic Center (ELVC) is a 15 km by 30 km area of nested calderas, stratovolcanoes, lava domes, hyaloclastite rings, and cinder cones aligned along the arc axis. Pavlof Volcano is the most active volcano along the ELVC, with more than 40 historic eruptions since 1790. The most recent eruption of Pavlof Volcano began in August 2007 after almost 11 years of quiescence. Mount Hague is a prominent intracaldera vent with no known historical eruptions that lies approximately 7 kilometers to the southwest of Pavlof. The southern crater of Mount Hague commonly fluctuates between a crater-filling lake to a dry crater floor with vigorously steaming fumaroles. Mount Hague has another fumarole field on the southeast flank at nearly the same elevation as the crater floor. To better document the behavior of persistent thermal features at these remote volcanoes, we have compiled temperature and dimension data using a seven-year long time series of satellite data. Over 25 daytime and 40 nighttime clear thermal infrared (TIR) images (90 m resolution) from the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) have recorded variations in the thermal activity at both volcanic vents since July 2000. All cloud-free ASTER TIR observations document persistent low- temperature features at both Pavlof Volcano and Mount Hague during this period. The size and temperature of each thermal feature varies throughout the study period. The data show that the 2518 m summit of Pavlof Volcano is occasionally snow-free in early summer whereas neighboring peaks at lower elevations are still snow-clad. FLIR data acquired near the summit of Pavlof in 2004 show that the majority of warm ground was at 20°C to 40°C. These warm areas commonly persist snow-free into the winter. Temperature variations observed at Mt Hague crater usually correlate to the size of the ephemeral crater lake. As the lake grows, the pixel-integrated ASTER TIR temperature increases. Measurements

    ALMA observations of the Galactic center with spatial resolution $2.61"\\times0.97"$ resulted in the detection of 11 SiO (5-4) clumps of molecular gas within 0.6pc (15$"$) of Sgr A*, interior to the 2-pc circumnuclear molecular ring. The three SiO (5-4) clumps closest to Sgr A* show the largest central velocities, $\\sim150$ \\kms, and broadest asymmetric linewidths with full width zero intensity (FWZI) $\\sim110-147$ \\kms. The remaining clumps, distributed mainly to the NE of the ionized mini-spiral, have narrow FWZI ($\\sim18-56$ \\kms). Using CARMA SiO (2-1) data, LVG modeling of the the SiO line ratios for the broad velocity clumps, constrains the column density N(SiO) $\\sim10^{14}$ cm$^{-2}$, and the H$_2$ gas density n$_{\\rm H_2}=(3-9)\\times10^5$ cm$^{-3}$ for an assumed kinetic temperature 100-200K. The SiO clumps are interpreted as highly embedded protostellar outflows, signifying an early stage of massive star formation near Sgr A* in the last $10^4-10^5$ years. Support for this interpretation is provided ...

    In order to observe the therapeutic effects of acupuncture on diabetic gastroparesis, 80 cases were divided randomly into 3 groups. In addition to the routine treatment for diabetes, 35 cases in the treatment group were additionally treated with acupuncture, and 25 cases in the control group 1 with domperidone, while 20 cases in the control group 2 with nothing. The three groups were all observed for 25 days. The results turned out to be that the total effective rate in the treatment group reached 94.2%, that in the control group 1, 72%, and in the control group 2, 40%, the treatment group showing a better therapeutic effect than the other two control groups (P<0.05, P<0.01). It can be concluded that in addition to the routine treatment for controlling blood sugar, acupuncture can give quite good therapeutic effects on diabetic gastroparesis.

  5. Knowledge domains cartography of the radiopharmacy center of IPEN - A case study

    International Nuclear Information System (INIS)

    Management of resources is effective only when the object is known in terms of their relevance, demand, availability, repositories and other pertinent characteristics that can influence its administration. Knowledge Management is not different and, in this case, knowledge mapping identifies resources, characterizes their attributes and repositories. An evaluation of this knowledge is also necessary in order to have a coherent Knowledge Management strategy that guarantees the continuity and the development of this resource according to the objectives and goals of the organization in terms of its vision of future. Evaluation allows measuring the critical character of the knowledge sources, facilitating the identification of those likely to add value and those that present risks the organization survival. This kind of diagnostic makes clear the Knowledge Management objectives and, consequently, unveil solutions that correspond to the organization's needs (capitalization and preservation; sharing, appropriation and knowledge creation). There are several ways to organize and to represent the knowledge resources of an organization. The approach here is a conceptual classification, that organizes the knowledge in a Cartography according to subjects, themes or purposes of common knowledge and it shows the decomposition of the activities of an organization under the point of view of knowledge domains. This model was used by Ermine. A Knowledge Management Project was applied in the Radiopharmacy Center (CR) of the Nuclear and Energetic Research Institute (IPEN), organ of the Nuclear Energy National Commission (CNEN) according to methodology following described. 1. CR was studied under the logic of its processes and its interfaces, considered as a Strategic Business Unit inside of the possible limits of a unit of IPEN.

    Quick, Jason

    2009-01-01

    The Upper Stage (US) section of the National Aeronautics and Space Administration's (NASA) Ares I rocket will require internal access platforms for maintenance tasks performed by humans inside the vehicle. Tasks will occur during expensive critical path operations at Kennedy Space Center (KSC) including vehicle stacking and launch preparation activities. Platforms must be translated through a small human access hatch, installed in an enclosed worksite environment, support the weight of ground operators and be removed before flight - and their design must minimize additional vehicle mass at attachment points. This paper describes the application of a user-centered conceptual design process and the unique challenges encountered within NASA's systems engineering culture focused on requirements and "heritage hardware". The NASA design team at Marshall Space Flight Center (MSFC) initiated the user-centered design process by studying heritage internal access kits and proposing new design concepts during brainstorming sessions. Simultaneously, they partnered with the Technology Transfer/Innovative Partnerships Program to research inflatable structures and dynamic scaffolding solutions that could enable ground operator access. While this creative, technology-oriented exploration was encouraged by upper management, some design stakeholders consistently opposed ideas utilizing novel, untested equipment. Subsequent collaboration with an engineering consulting firm improved the technical credibility of several options, however, there was continued resistance from team members focused on meeting system requirements with pre-certified hardware. After a six-month idea-generating phase, an intensive six-week effort produced viable design concepts that justified additional vehicle mass while optimizing the human factors of platform installation and use. Although these selected final concepts closely resemble heritage internal access platforms, challenges from the application of the

  20. ALMA OBSERVATIONS OF THE GALACTIC CENTER: SiO OUTFLOWS AND HIGH-MASS STAR FORMATION NEAR Sgr A*

    International Nuclear Information System (INIS)

    ALMA observations of the Galactic center with a spatial resolution of 2.''61 × 0.''97 resulted in the detection of 11 SiO (5-4) clumps of molecular gas within 0.6 pc (15'') of Sgr A*, interior to the 2 pc circumnuclear molecular ring. The three SiO (5-4) clumps closest to Sgr A* show the largest central velocities, ∼150 km s–1, and the broadest asymmetric line widths with full width zero intensity (FWZI) ∼110-147 km s–1. The remaining clumps, distributed mainly to the NE of the ionized mini-spiral, have narrow FWZI (∼18-56 km s–1). Using CARMA SiO (2-1) data, Large Velocity Gradient modeling of the SiO line ratios for the broad velocity clumps constrains the column density N(SiO) ∼1014 cm–2, and the H2 gas density nH2 = (3-9) x 105 cm–3 for an assumed kinetic temperature 100-200 K. The SiO clumps are interpreted as highly embedded protostellar outflows, signifying an early stage of massive star formation near Sgr A* in the last 104-105 yr. Support for this interpretation is provided by the SiO (5-4) line luminosities and velocity widths which lie in the range measured for protostellar outflows in star-forming regions in the Galaxy. Furthermore, spectral energy distribution modeling of stellar sources shows two young stellar object candidates near SiO clumps, supporting in situ star formation near Sgr A*. We discuss the nature of star formation where the gravitational potential of the black hole dominates. In particular, we suggest that external radiative pressure exerted on self-shielded molecular clouds enhances the gas density, before the gas cloud becomes gravitationally unstable near Sgr A*. Alternatively, collisions between clumps in the ring may trigger gravitational collapse.

    Using ALMA observations of the Galactic center with a spatial resolution of 2.61" x 0.97 ", we detected 11 SiO (5-4) clumps of molecular gas in the within 0.6pc (15") of Sgr A*, interior of the 2-pc circumnuclear molecular ring. Three SiO (5-4) clumps closest to Sgr A* show the largest central velocities of approximately 150 kilometers per second and broadest asymmetric linewidths with total linewidths FWZI approximately 110-147 kilometers per second. Other clumps are distributed mainly to the NE of the ionized minispiral with narrow linewidths of FWHM approximately 11-27 kilometers per second. Using CARMA data, LVG modeling of the broad velocity clumps, the SiO (5-4) and (2-1) line ratios constrain the column density N(SiO) approximately 10(exp 14) per square centimeter, and the H2 gas density n(sub H2) = (3-9) x 10(exp 5) per cubic centimeter for an assumed kinetic temperature 100-200K. The SiO (5-4) clumps with broad and narrow linewidths are interpreted as highly embedded protostellar outflows, signifying an early stage of massive star formation near Sgr A* in the last 104 years. Additional support for the presence of YSO outflows is that the luminosities and velocity widths lie in the range detected from protostellar outflows in star forming regions in the Galaxy. Furthermore, SED modeling of stellar sources along the N arm show two YSO candidates near SiO clumps supporting in-situ star formation near Sgr A*. We discuss the nature of star formation where the gravitational potential of the black hole dominates. In particular, we suggest that external radiative pressure exerted on self-shielded molecular clouds enhance the gas density, before the gas cloud become gravitationally unstable near Sgr A*.

  6. FIRST CASE OF AUTOCHTHONOUS HUMAN VISCERAL LEISHMANIASIS IN THE URBAN CENTER OF RIO DE JANEIRO: CASE REPORT

    Directory of Open Access Journals (Sweden)

    Guilherme Almeida Rosa da Silva

    2014-01-01

    Full Text Available Visceral leishmaniasis is an anthropozoonosis that is caused by protozoa of the genus Leishmania, especially Leishmania (Leishmania infantum, and is transmitted to humans by the bite of sandflies of the genus Lutzomyia, such as Lutzomyia longipalpis. There are many reservoirs, including Canis familiaris. It is a chronic infectious disease with systemic involvement that is characterized by three phases: the initial period, the state period and the final period. The main symptoms are fever, malnutrition, hepatosplenomegaly, and pancytopenia. This article reports a case of a patient diagnosed with visceral leishmaniasis in the final period following autochthonous transmission in the urban area of Rio de Janeiro. The case reported here is considered by the Municipal Civil Defense and Health Surveillance of Rio de Janeiro to be the first instance of autochthonous visceral leishmaniasis in humans in the urban area of this city. The patient was discharged and is undergoing a follow-up at the outpatient clinic, demonstrating clinical improvement.

  7. Intravenous leiomyomatosis revisited: an experience of 14 cases at a single medical center.

    2015-03-01

    Intravenous leiomyomatosis (IVL) is a rare neoplasm of smooth muscle origin with the capacity for distant vascular and/or organ extension. The primary lesion is typically found in the uterus, with the most common extrauterine sites being pelvic/broad ligament vessels, and less often inferior vena cava, right heart chambers, and pulmonary vasculature. Extrauterine involvement can result in direct mass effect or vascular obstruction with associated clinical sequelae. Fourteen cases of IVL were identified in our pathology archives over a 25-yr period. Patient medical records and gross pathologic findings were reviewed. Histologic and related immunohistochemical slides (smooth muscle actin, desmin, CD31, CD34, and CD10) were re-evaluated by 2 gynecologic pathologists to confirm the diagnosis using conventional diagnostic criteria. Patient age at initial diagnosis ranged from 35 to 64 yr (mean: 46.1 yr), with a median age of 45 yr. Four cases demonstrated extrauterine extension, 2 cases were associated with disease recurrence, and 1 case was found to be extrauterine in origin (i.e. arising from the broad ligament). In summary, our study represents the fourth largest IVL cohort in literature to date, and contains the first case of IVL arising from the broad ligament in the absence of a uterine mass. IVL is a rare and potentially underdiagnosed neoplastic condition of smooth muscle origin that may result in significant morbidity when extrauterine vasculature or organs are involved. A high index of suspicion must be maintained, as the histologic diagnosis may be particularly challenging in cases in which the intracaval/intracardiac portion of the tumor is removed before the uterine IVL diagnosis, or a significant interval of time has elapsed since the initial IVL diagnosis was made. Prompt diagnosis combined with surgical excision has been shown to portend an increased survival rate and good overall prognosis in such cases. PMID:25675187

  11. Recombination luminescence from H centers and conversion of H centers into I centers in alkali iodides

    International Nuclear Information System (INIS)

    The study is aimed at the search for H-plus-electron centers of luminescence and the investigation of the conversion of H- into I centers by the luminescence of H-plus-electron centers in alkali iodide crystals. KI, RbI and NaI crystals were studied at 12 K. H and F centers were created by irradiation with ultraviolet light corresponding to the absorption band of anion excitons. Then the excitation of electron centers by red light irradiation was followed. The spectra of stimulated recombination luminescence were studied. The luminescence of H-plus- electron centers had been observed and the conclusion was made that this center was formed on immobile H centers. In case of stable H centers the optically stimulated conversion of H centers into I centers occurs. The assumption is advanced on the spontaneous annihilation of near placed unstable F, H centers which leads to the creation of H-plus-electron luminescence centers and to the spontaneous H-I-centers conversion

    2008-07-01

    Senior managers of children's mental health centers across Ontario, Canada were interviewed regarding the challenges and solutions of access and delivery of care. The central challenges--funding, case complexity, waitlists, staffing, and system integration--revealed a complex interplay between the policies and financing of children's mental health services and the provision of clinical services at the agency level and within the community. The desire for integration and collaboration was countered by competition for funding and service demands. A need for policies that allow for local solutions while providing leadership for sustained improvements in the ease and timeliness of access to care and effective clinical services emerged.

    2015-01-01

    The origin of irradiation and fluorescence of the 6.4 keV bright giant molecular clouds surrounding Sgr A*, the central supermassive black hole of our Galaxy, remains enigmatic. Testing the theory of a past active period of Sgr A* requires X-ray polarimetry. In this paper, we show how modern imaging polarimeters could revolutionize our understanding of the Galactic Center. Through Monte Carlo modeling, we produce a 4-8 keV polarization map of the Galactic Center, focusing on the polarimetric signature produced by Sgr B1, Sgr B2, G0.11-0.11, Bridge E, Bridge D, Bridge B2, MC2, MC1, Sgr C3, Sgr C2, and Sgr C1. We estimate the resulting polarization, include polarized flux dilution by the diffuse plasma emission detected toward the GC, and simulate the polarization map that modern polarimetric detectors would obtain assuming the performances of a mission prototype. The eleven reflection nebulae investigated in this paper present a variety of polarization signatures, ranging from nearly unpolarized to highly pola...

    In the first of two parts, this article provides an outline of key steps in creating a freestanding diagnostic imaging center (Genesis HealthCare System located in Zanesville, OH) and provides details on a few of the significant processes. The following are highlighted in this article: Overview, market assessment, facility design, and equipment selection. Part 2 will feature operational process improvements. The length of the Genesis project extended to about 18 months due to the added services of urgent care and a community education and meeting facility. The project began in July 2005 and was completed in January 2006 (if the project was focused only on imaging, it could have been complete in about 8 to 10 months, see Figure 1 for a typical summary work task timeline). This multi-service outpatient center, The Genesis Healthplex on Maple, was created in an existing facility that was once a large grocery store. A significant goal that came out of the project was to create the perfect customer experience. The customer is defined as: Patients, patient families, referring physicians and their staff, radiologists, and employees. This was achieved by bringing the 3 entities of people (patient/family, staff, and physicians) working closely together by utilizing well identified processes and employing technology that the market demands. Only when these areas overlap and work together will the perfect customer experience be created. See Figure 2. PMID:17191544

  16. Statistical observation on autopsy cases of malignancy at the Japanese Red Cross, Nagasaki Atomic Bomb Hospital

    International Nuclear Information System (INIS)

    Statistical observation was made as to autopsy cases of atomic-bomb survivors in Nagasaki. The total of autopsy cases at the Japanese Red Cross, Nagasaki Atomic Bomb Hospital from the opening of the hospital, 1968, to December in 1975 was 1,486 cases (autopsy rate, 65.1%) in which 880 cases of atomic bomb survivors (autopsy rate, 68.0%) were contained. Cases of malignancy totaled 829 and 528 cases of those were atomic bomb survivors. Cases of malignancy were divided into three groups, that is, group exposured to atomic bomb at place within 2 km from the explosion place, group exposured at place from more than 2 km or entering after explosion into the city, and not-exposured group. Relationship between main malignancies and exposure was discussed, and the following results were obtained. 1) Obvious relationship was found to exist between exposure and acute and chronic medullary leukemia. 2) Malignant lymphoma was scarecely correlated with exposure, but its occurrence rate was higher than the mean rate in Japan in reflection the region where this disease occurs much geographically. 3) Relationship between exposure and stomach cancer, lung cancer, cancer of the large intestine, and double cancer was not found obviously, but occurrence rate of hepatic cancer was higher than the mean rate in Japan in three groups. The reason was supposed to be geographical factor. 4) Cases of thyroid gland cancer were a small number in female of the group exposured within 2 km, and cases of prostate cancer were a small number in the group within 2 km, but their occurrence rate was high specifically.

    Full Text Available Introduction & Background: Benign lesions are very common in breast. The most important consideration for physicians is to differentiate benign processes from malignant ones .Hence the clinicians and radi-ologists both wish to differentiate them even before surgical procedures. The Iranian Center for Breast Cancer linked to Jahad Daneshgahi Center is a referral place for patients with breast complaints. Patients & Methods: Retrospective study of sonographic findings of 111 patients with benign patho-logic diagnosis revealed 72.1% accuracy for sonogra-phy in diagnosing benign masses. In 31 cases (27.9%, the sonographic diagnosis was incorrect. Among the different benign lesions, the most common lesions were cysts, fibradenomas, and fibrocystic changes with respective sonographic accuracy of 100%, 90%, and 62.5%. Results: It shows that sonography has a high sensitiv-ity for diagnosis of benign breast lesions and this sen-sitivity is higher in cysts and fibradenomas which are the most common benign pathologies of breast. Conclusion: As a result, in this center sonography is an imaging modality for evaluating benign breast le-sion especially in young patients with dense breasts and palpable masses. Its unique role in diagnosis of the cysts is valuable especially to avoid repeated biopsies.

  20. Management of groundwater in urban centers: A case study; Greater Dammam Metropolitan Area

    International Nuclear Information System (INIS)

    Effective management of groundwater resources in urban centers of arid regions is vital for sustainable development and groundwater protection especially with rapid growth of water demands under water stress conditions. Greater Dammam Metropolitan Area is a good example of rapid growing urban center due to comprehensive development and population growth. The water demand has increased by many times during the last three decades. Groundwater from local aquifers namely Dammam and Umm Er Radhuma, supplies more than 85% of the total water demands. The aquifers have been subjected to extensive and increasing groundwater pumping especially during last three decades. Negative impacts such as significant decline in water levels have been experienced in the area. A new groundwater management scheme in terms of improving the long-term water pumping policies is required for protection of the aquifers groundwater productivity. A special numerical simulation model of the multi-aquifer system including Dammam and Umm Er Radhuma aquifers has been developed to assess the behavior of the aquifer system under long term water stresses in Dammam Metropolitan Area. The developed numerical simulation model has been utilized to predict the responses of the aquifer system in terms of decline in terms of water level under different pumping schemes from the two aquifers during the next 30 years. The model results have postulated the importance of Umm Er Radhuma (UER) aquifer as a major water supply source to Dammam Metropolitan Area, as well as potential recharge source of more than 30% of the total water pumped from Dammam aquifer. These findings have been utilized in improving present and future groundwater management and conservation for the study area. Similar techniques can be used to improve the groundwater management in other parts of the country as well as other arid regions. (author)

    Full Text Available Background and Design: Bullous pemphigoid (BP is a chronic, autoimmune, subepidermal blistering disease. The aim of this study was to determine the clinico-epidemiologic data’s of patients diagnosed as BP in our clinic and compare these data with other studies in our country and in the world. Material and Method: We researched the documents of BP cases diagnosed by clinical and histopathological examinations from January 2009 to January 2013, retrospectively. We evaluated clinical and dermographical characteristics of all patients such as age, sex, existence of oral mucosal lesions, association of pruritus, duration of disease, presence of triggering factors, features of skin lesions, results of direct immunofluorescence (DIF investigation, drug intake, recurrence and mortality rates and causes of detected mortality. Results: Of the 29 patients included in the study %48,3 were female, %51,7 were male. The average age was 70,17 and the mean duration of disease was 15.41 months. In five cases oral mucosal involvement and in 24 cases pruritus was detected. Drugs in three cases and malignity in one case were assessed as triggering factors. The results of DIF investigation revealed the linear IgG and C3 deposition at the dermoepidermal junction in 12 cases, C3 deposition in 10 cases. The initial treatment was topical corticosteroid in 11, tetracycline and nicotinamide combination in six, systemic corticosteroid in 10 individuals. After initial therapy recurrence appeared in 7 patients in one year. Mortality during hospitalization was observed in 2 cases. Conclusions: We presented the clinical and epidemiological features of patients diagnosed as BP in our clinics in the last three years. Because of having different ethnical originated, heterogeneous population of our city, we believe that our investigation will contribute to having opinion about epidemiology of BP in our country. Nevertheless, prospective, long term and multicentre studies based on

    Full Text Available Abstract Introduction Nasopharyngeal cancer commonly manifests with cervical lymphadenopathy, recurrent epistaxis and progressive nasal obstruction. Neuro-ophthalmic and otologic manifestations can also occur. Isolated otologic presentations of nasopharyngeal cancer are rare and the diagnosis of nasopharyngeal cancer may not be foremost in the list of differentials. Case presentation We present the case of a 29-year-old Nigerian woman with bilateral conductive hearing loss and tinnitus after air travel. There were no other symptoms. The persistence of the symptoms after adequate treatment for otitic barotrauma necessitated re-evaluation, which led to a diagnosis of nasopharyngeal cancer. Conclusion Isolated otologic manifestations of nasopharyngeal cancer are rare in regions with low incidence of the disease. There is a need for it to be considered as a possible differential in patients presenting with bilateral serous otitis media.

    This article reports a satisfactory result through the observation of 42 cases of soft tissue inflammation treated by nitrogen molecular laser including 22 cases that failed under treatment of antibiotic and ultraviolet ray. Of the 42 cases reviewed, 34 patients recovered. The average of recovery days was 13.8 days; 8 patients made obvious progress in recovering. Compared with the therapeutic results of ultraviolet ray, nitrogen molecular laser could get the same results with ultraviolet ray in an acute stage of inflammation, and it could shorten the course of disease and raise the cure rate for chronic soft tissue inflammation and delay in wound healing. The following is a brief introduction of the comparison between nitrogen molecular laser and the antibiotic and ultraviolet ray.

    Full Text Available Nebulized colistin (NC is used for the treatment of pneumonia due to multidrug-resistant Gram-negative bacteria. In this one-year case-control study, our objective was to evaluate the effect of NC on the ventilator circuit (VC components. The case group consisted of 25 mechanically-ventilated patients who received NC, while the control group was 25 mechanically-ventilated patients who did not receive NC. Respiratory therapists inspected the VC every 4 hrs and whenever a ventilator alarm was reported. The VC component was changed if the alarm did not subside after necessary measures were performed. Patients from both groups were treated at the adult ICU in King Hussein Cancer Center (KHCC. In the case group, 22(88% patients required changing at least one of the circuit components (flow sensor, exhalation membrane, or nebulizer kit. The median number of changes (range per patient of the flow sensor, exhalation membrane, and nebulizer kit were: 2(1-3, 2(1-6, and 1(1-2, respectively. Large amounts of white crystals, which resembled the colistin powder, were reported on the replaced VC components. The flow sensor was changed in 2 control patients, but white crystals were absent. Crystals obtained from one case subject were confirmed to be colistin by chromatographic mass spectroscopy. Further studies are needed to evaluate the effect of crystal formation on the efficacy of NC and clinical outcomes.

    Full Text Available Abstract   Distribution of goods and services in cities is of utmost importance. Selecting appropriate venues for different service centers in a city not only enables the citizens to access these services much more easily, but also reduces the traffic load caused by trips made to reach them. Unfortunately, the lack of a correct urban planning has led to inappropriate formation of many cities around the world in terms of the locations assumed for different service centers. Since the private sector has been given the responsibility to construct most of these centers, changing their current locations may be restricted due to legal obligations. Therefore, it seems necessary for the government to construct new service centers with high competitive facilities to attract customers and to compete with those built by the private sector. In this paper, the selection of appropriate locations to construct new service centers has been studied. Such locations have been selected in a way to fulfill goals such as rapid and easy accessibility for the customers and reduction of traffic drawbacks caused by the related trips. In this regard, a model for service centers with restricted capacity has been designed and a parallel simulated annealing algorithm has been proposed to solve it. Finally, the proposed algorithm has been utilized to locate the health centers around the city of Isfahan and its efficiency has been investigated. The findings highlight the accuracy and speed of the proposed algorithm in location of the health centers of Isfahan.

    We developed a computerised test to evaluate unilateral spatial neglect (USN) using a touchscreen display, and estimated the spatial and temporal patterns of visual search in USN patients. The results between a viewer-centered USN patient and a stimulus-centered USN patient were compared. Two right-brain-damaged patients with USN, a patient without USN, and 16 healthy subjects performed a simple cancellation test, the circle test, a visuomotor search test, and a visual search test. According to the results of the circle test, one USN patient had stimulus-centered neglect and a one had viewer-centered neglect. The spatial and temporal patterns of these two USN patients were compared. The spatial and temporal patterns of cancellation were different in the stimulus-centered USN patient and the viewer-centered USN patient. The viewer-centered USN patient completed the simple cancellation task, but paused when transferring from the right side to the left side of the display. Unexpectedly, this patient did not exhibit rightward attention bias on the visuomotor and visual search tests, but the stimulus-centered USN patient did. The computer-based assessment system provided information on the dynamic visual search strategy of patients with USN. The spatial and temporal pattern of cancellation and visual search were different across the two patients with different subtypes of neglect. PMID:26059555

    Full Text Available Structural and qualitative evaluation of Revised National Tuberculosis Control Programme (RNTCP is important to determine actual status of the programme in the field settings and to uncover the concealed gaps. The present cross-sectional study assessed the infrastructural facilities and quality of services provided through microscopy and directly observed treatment (DOT centers at Nanded city of Maharashtra. The investigator made on spot observation on the activities at microscopy and DOT centers and assessed the infrastructural facilities using an observational checklist. Expert microbiologist cross checked the microscopy report done by the laboratory technicians. It revealed that retrieval mechanism was not functioning in more than half of the DOT centers. Only 5 DOT providers were trained in RNTCP. Stock of sputum containers, methylene blue, and carbol fuchsin was found to be inadequate at some microscopy centers. Half of the laboratory technicians reported high false positive result in spite of being trained. Improvement of infrastructural and logistic support along with the refreshing training for the workers are needed for effective implementation of RNTCP.

    Recent floods along the Atlantic and Gulf seaboards and elsewhere in the world before Katrina had demonstrated the complexity of public health impacts including trauma; fires; chemical, sewerage, and corpse contamination of air and water; and diseases. We realized that Louisiana's vulnerability was exacerbated because forty percent of the state is coastal zone in which 70% of the population resides. Ninety percent of this zone is near or below sea level and protected by man-made hurricane-protection levees. New Orleans ranked among the highest in the nation with respect to potential societal, mortality, and economic impacts. Recognizing that emergency responders had in the past been unprepared for the extent of the public health impacts of these complex flooding disasters, we created a multi-disciplinary, multi-campus research center to address these issues for New Orleans. The Louisiana Board of Regents, through its millennium Health Excellence Fund, awarded a 5-year contract to the Center in 2001. The research team combined the resources of natural scientists, social scientists, engineers, and the mental health and medical communities. We met annually with a Board of Advisors, made up of federal, state, local government, and non-governmental agency officials, first responders and emergency managers. Their advice was invaluable in acquiring various datasets and directing aspects of the various research efforts. Our center developed detailed models for assessment and amelioration of public health impacts due to hurricanes and major floods. Initial research had showed that a Category 3 storm would cause levee overtopping, and that most levee systems were unprotected from the impacts of storm-induced wave erosion. Sections of levees with distinct sags suggested the beginnings of foundation and subsidence problems. We recognized that a slow moving Cat 3 could flood up to the eaves of houses and would have residence times of weeks. The resultant mix of sewage, corpses

    Full Text Available Abstract Background Behavioral health services for children and adolescents in the U.S. are lacking in accessibility, availability and quality. Evidence-based interventions for emotional and behavioral disorders can improve quality, yet few studies have systematically examined their implementation in routine care settings. Methods Using quantitative and qualitative data, we evaluated a multi-faceted implementation strategy to implement cognitive-behavioral therapy (CBT for depressed adolescents into two publicly-funded mental healthcare centers. Extent of implementation during the study's duration and variables influencing implementation were explored. Results Of the 35 clinicians eligible to participate, 25 (71% were randomized into intervention (n = 11 or usual care (n = 14. Nine intervention clinicians completed the CBT training. Sixteen adolescents were enrolled in CBT with six of the intervention clinicians; half of these received at least six CBT manually-based sessions. Multiple barriers to CBT adoption and sustained use were identified by clinicians in qualitative interviews. Conclusion Strategies to implement evidence-based interventions into routine clinical settings should include multi-method, pre-implementation assessments of the clinical environment and address multiple barriers to initial uptake as well as long-term sustainability.

    Full Text Available Abstract Background Following the demise of Jordan's King Hussein bin Talal to cancer in 1999, the country's Al-Amal Center was transformed from a poorly perceived and ineffectual cancer care institution into a Western-style comprehensive cancer center. Renamed King Hussein Cancer Center (KHCC, it achieved improved levels of quality, expanded cancer care services and achieved Joint Commission International accreditation under new leadership over a three-year period (2002–2005. Methods An exploratory case research method was used to explain the rapid change to international standards. Sources including personal interviews, document review and on-site observations were combined to conduct a robust examination of KHCC's rapid changes. Results The changes which occurred at the KHCC during its formation and leading up to its Joint Commission International (JCI accreditation can be understood within the conceptual frame of the transformational leadership model. Interviewees and other sources for the case study suggest the use of inspirational motivation, idealized influence, individualized consideration and intellectual stimulation, four factors in the transformational leadership model, had significant impact upon the attitudes and motivation of staff within KHCC. Changes in the institution were achieved through increased motivation and positive attitudes toward the use of JCI continuous improvement processes as well as increased professional training. The case study suggests the role of culture and political sensitivity needs re-definition and expansion within the transformational leadership model to adequately explain leadership in the context of globalizing health care services, specifically when governments are involved in the change initiative. Conclusion The KHCC case underscores the utility of the transformational leadership model in an international health care context. To understand leadership in globalizing health care services, KHCC

    2014-04-01

    Full Text Available At the infant-toddler center, the rituals of transition that mark children’s arrival and going home times offer interesting kaleidoscopes for the study of interactive dynamics with the associated meanings and implicit educational models. Numerous pedagogical studies have investigated the meanings of these events, for the most part drawing on the monocultural model of classical attachment theory to analyze interactions between adults and children. Far less research has approached these rituals using triadic, systemic and intercultural categories of analysis in order to explore not only educators’ actions but also what is going on in their minds. In this paper, we discuss examples from a recent study on rituals of transition in the multicultural context of an infant toddler center, combining description of the timing, behaviors and interactive styles of children and adults, with analysis of the thoughts and representations of the educators.

  16. Radiotherapy of Painful Vertebral Hemangiomas: The Single Center Retrospective Analysis of 137 Cases

    International Nuclear Information System (INIS)

    Purpose: An evaluation of dose–response relationship and an attempt to define predictive factors. Methods and Materials: A total of 137 cases of painful vertebral hemangioma irradiations (101 patients). Fraction dose (fd) varied from 2 to 15 Gy (123 fractionated and 14 radiosurgical treatments), and total dose (TD) from 8 to 30 Gy (111 cases irradiated with fd of 2 GY to TD of 24 Gy). We evaluated pain relief, changes in analgesic requirements, and reossification. Results: Means of pain relief 1, 6, 12, and 18 months after radiotherapy (defined as a decrease of primary pain level expressed in percent) were 60.5%, 65.4%, 68.3%, and 78.4%, respectively. Proportion of patients with no need for analgesics and patients using tramadol were 39%, 40%, 44%, 57%, and 20%, 17%, 22%, and 11% in these times. The proportion of patients experiencing complete/partial pain relief changed from 36/48% 1 month, to 64/22% 1.5 years after radiotherapy. No impact of radiotherapy on reossification was found. The positive impact of fd and TD increase for analgesics uptake reduction and pain relief was found. An increase of the fd by 1 Gy results in 27% chance of analgesics uptake reduction and 3.8% reduction of pain, whereas 14% analgesics uptake reduction and 2.2% of pain reduction in case of the TD. The predictive factors improving results were found: female gender, older age, better performance states (the chance of the lower analgesic treatment decreases over 2.5 times in comparison to the higher Zubrod degree), bigger Hb concentration, shorter symptoms duration and lower analgesics uptake before radiotherapy. Conclusions: The obtained data support the efficacy of radiotherapy in improving pain secondary to vertebral hemangioma, with the degree of pain amelioration being related to increasing fd and TD. The positive predictive factors were defined: female gender, older age, better performance status, increased Hb concentration, shorter symptoms duration, and lower analgesics uptake

    Well-founded ontologies are key to enabling transformative semantic technologies and accelerating scientific research. One example is semantically enabled search and discovery, making scientific data accessible and more understandable by accurately modeling a complex domain. The ontology creation process remains a challenge for many anxious to pursue semantic technologies. The key may be that the creation process -- whether formal, community-based, automated or semi-automated -- should encompass not only a foundational core and supplemental resources but also a focus on the purpose or mission the ontology is created to support. Are there tools or processes to de-mystify, assess or enhance the resulting ontology? We suggest that comparison and analysis of a domain-focused ontology can be made using text engineering tools for information extraction, tokenizers, named entity transducers and others. The results are analyzed to ensure the ontology reflects the core purpose of the domain's mission and that the ontology integrates and describes the supporting data in the language of the domain - how the science is analyzed and discussed among all users of the data. Commonalities and relationships among domain resources describing the Clouds and Earth's Radiant Energy (CERES) Bi-Directional Scan (BDS) datasets from NASA's Atmospheric Science Data Center are compared. The domain resources include: a formal ontology created for CERES; scientific works such as papers, conference proceedings and notes; information extracted from the datasets (i.e., header metadata); and BDS scientific documentation (Algorithm Theoretical Basis Documents, collection guides, data quality summaries and others). These resources are analyzed using the open source software General Architecture for Text Engineering, a mature framework for computational tasks involving human language.

    Aggressive behavior in traffic is a widespread phenomenon. Up to 90% of the population are involved in mild forms such as shouting or gesturing. More dramatic cases with injury to individuals affect at least 1100 people in the US annually. Certain factors such as a male sex, a young age and an urban residency have been identified to contribute to the likelihood of road rage. Central to this analysis is the determination of specific features regarding the conflicting parties, the crime scene and the injury pattern in violent offenses related to traffic. In a retrospective study spanning 10 years, cases of road rage-linked injuries were identified amongst patients at the Medico-Legal Center of the Institute of Legal Medicine in Hamburg, Germany. The data were digitized and then analyzed using descriptive statistics via SPSS. There are disproportionately large numbers of males (85.7%) and motorists (61.2%) amongst road rage perpetrators. Usually the conflicting parties have no prior relationship (89.7%). In 68.1% of the cases, the violence applied was exclusively physical. Objects were utilized in 31.0% of all cases, and in more than half (55.6%) of these cases the vehicle was used as a weapon. The resulting trauma in road rage is mostly blunt and applied to the face and the extremities. There are characteristic features regarding the demographics, time and place of incident, as well as severity and pattern of injury in road rage associated offenses. Identifying these factors may lead to appropriate measures in the reduction of road rage. PMID:26817969

    Full Text Available Taking into consideration satisfied customer as necessary for business maintenance, companies are trying to discover determinants which have the biggest influence on their consumer satisfaction. Here are presented two factors that have influence on consumer satisfaction in shopping centers: quality of shopping and corporate social responsibility. In this research, each of these factors had six elements. The results of the regression analysis are that “Value for money in stores” (beta=0.387, p=0.000 has the greatest impact on satisfaction when shopping quality performance is concerned, and that “Retailer support for (national/local cultural and sport events“ (beta=0.333, p<0.001 has the greatest impact on satisfaction in the case of CSR performance. Further analysis showed the difference in consumer perception of corporate social responsibility, depending on their occupation and level of education. It is also important to mention that consumers with environment and empathic concern have higher scores perception of CSR. However, there is not statistically important difference in consumer perception of shopping quality in shopping centers

    The Center for Disease Control's (CDC) Diethylstilbestrol (DES) Update, a campaign to educate people who may have been exposed to the drug DES, is framed on the premises of the social marketing model, namely formative research, audience segmentation, product, price, placement, promotion, and campaign evaluation. More than that, the campaign takes a critical step in extending the social marketing paradigm by highlighting the need to situate the messaging process at the heart of any health communication campaign. This article uses CDC's DES Update as a case study to illustrate an application of a message development tool within social marketing. This tool promotes the operationalization of messaging within health campaigns. Ultimately, the goal of this project is to extend the social marketing model and provide useful theoretical guidance to health campaign practitioners on how to accomplish stellar communication within a social marketing campaign.

  11. Pancreaticoduodenectomy in a tertiary referral center in Saudi Arabia: A retrospective case series

    International Nuclear Information System (INIS)

    Context: Perioperative outcome of pancreaticoduodenectomy is related to work load volume and to whether the procedure is carried out in a tertiary specialized hepato-pancreatico-biliary (HPB) unit. Objective: To evaluate the perioperative outcome associated with pancreaticoduodenectomy in a newly established HPB unit. Patients: Analysis of 32 patients who underwent pancreaticoduodenectomy (PD) for benign and malignant indications. Design: Retrospective collection of data on preoperative, intraoperative and postoperative care of all patients undergoing PD. Results: Thirty-two patients (16 male and 16 female) with a mean age of 59.5 ± 12.7 years were analyzed. The overall morbidity rate was high at 53%. The most common complication was wound infection (n = 11; 34.4%). Pancreatic and biliary leaks were seen in 5 (15.6%) and 2 (6.2%) cases, respectively, while delayed gastric emptying was recorded in 7 (21.9%). The female sex was not associated with increased morbidity. Presence of co-morbid illness, pylorus-preserving PD, intra-operative blood loss > 1 L, and perioperative blood transfusion were not associated with significantly increased morbidity. The overall hospital mortality was 3.1% and the cumulative overall (OS) and disease free survival (DFS) at 1 year were 80% and 82.3%, respectively. The cumulative overall survival for pancreatic cancer vs ampullary tumor at 1 year were 52% vs 80%, respectively. Conclusion: PD is associated with a low risk of operative death when performed by specialized HPB surgeons even in a tertiary referral hospital. However, the postoperative morbidity rate remains high, mostly due to wound infection. Further improvement by reducing postoperative infection may help curtail the high postoperative morbidity

    The detection of gamma-rays from the source HESS J1745-290 in the Galactic Center (GC) region with the H.E.S.S. array of Cherenkov telescopes in 2004 is presented. After subtraction of the diffuse gamma-ray emission from the GC ridge, the source is compatible with a point-source with spatial extent less than 1.2'(stat.) (95% CL). The measured energy spectrum above 160 GeV is compatible with a power-law with photon index of 2.25 +/- 0.04(stat.) +/- 0.10 (syst.) and no significant flux variation is detected. These measurements are discussed in the framework of dark matter annihilation. It is found that the bulk of the VHE emission must have non-dark-matter origin. Loose constraints on the velocity-weighted annihilation cross section are derived assuming the presence of an astrophysical non-dark-matter gamma-ray contribution.

    2012-02-01

    Our previous Single Photon Emission Computed Tomography (SPECT) myocardial perfusion imaging (MPI) research explored the utility of numerical observers. We recently created two hundred and eighty simulated SPECT cardiac cases using Dynamic MCAT (DMCAT) and SIMIND Monte Carlo tools. All simulated cases were then processed with two reconstruction methods: iterative ordered subset expectation maximization (OSEM) and filtered back-projection (FBP). Observer study sets were assembled for both OSEM and FBP methods. Five physicians performed an observer study on one hundred and seventy-nine images from the simulated cases. The observer task was to indicate detection of any myocardial perfusion defect using the American Society of Nuclear Cardiology (ASNC) 17-segment cardiac model and the ASNC five-scale rating guidelines. Human observer Receiver Operating Characteristic (ROC) studies established the guidelines for the subsequent evaluation of numerical model observer (NO) performance. Several NOs were formulated and their performance was compared with the human observer performance. One type of NO was based on evaluation of a cardiac polar map that had been pre-processed using a gradient-magnitude watershed segmentation algorithm. The second type of NO was also based on analysis of a cardiac polar map but with use of a priori calculated average image derived from an ensemble of normal cases.

    2016-01-01

    Background: Patients with significant bilateral carotid artery stenosis requiring urgent cardiac surgery have an increased risk of stroke and death. The optimal management strategy remains inconclusive, and the available evidence does not support the superiority of one strategy over another. Materials and Methods: A number of noninvasive strategies have been developed for minimizing perioperative stroke including continuous real-time monitoring of cerebral oxygenation with near-infrared spectroscopy (NIRS). The number of patients presenting with this combination (bilateral significant carotid stenosis requiring urgent cardiac surgery) in any single institution will be small and hence there is a lack of large randomized studies. Results: This case series describes our early experience with NIRS in a select group of patients with significant bilateral carotid stenosis undergoing urgent cardiac surgery (n = 8). In contrast to other studies, this series is a single surgeon, single center study, where the entire surgery (both distal ends and proximal ends) was performed during single aortic clamp technique, which effectively removes several confounding variables. NIRS monitoring led to the early recognition of decreased cerebral oxygenation, and corrective steps (increased cardiopulmonary bypass flow, increased pCO2, etc.,) were taken. Conclusion: The study shows good clinical outcome with the use of NIRS. This is our “work in progress,” and we aim to conduct a larger study. PMID:26750675

    Full Text Available According to the World Health Organization (WHO in 2014, about 800 mothers die worldwide each day from complications related to pregnancy or childbirth. Each year approximately 20,000 women in Indonesia die from causes related to pregnancy and labor. The purpose of this study was to determine the incidence of pregnancy complications determinant in Abepura, Jayapura City Health Center in 2015. This study was an observational study design with "cross-sectional study", which is one type of the analytic study design. The sample in this study is the third trimester pregnant women who visited antenatal at health centers Abepura totaling 155 people using accidental sampling technique. All data in this study were collected through interviews using questionnaires. Analysis of the data in this study include univariate, bivariate (chi square and multivariate (logistic regression. Chi-square test results demonstrated an association iron tablet intake (p = 0.022; RP = 2, maternal age (p = 0.018; RP = 2.6, parity (p = 0.03; RP = 1.9, a history of pregnancy complications (p = 0.0001; RP = 2.9, and a history of birth complications (p = 0.002; RP = 2.6 and the incidence of pregnancy complications. While the history of infectious disease has no relationship with the incidence of pregnancy complications (p = 0.214; RP = 1.4. Multivariate analysis showed that maternal age and previous pregnancy complications are dominant factors on the incidence of pregnancy complications.

    Full Text Available Aerosol nucleation events observed worldwide may have significant climatic and health implications. However, the specific nucleation mechanisms remain ambiguous. Here, we report case studies of six nucleation events observed during an intensive field campaign at a boreal forest site (Hyytiälä, Finland in spring 2005. The present analysis is based on comprehensive kinetic simulations using an ion-mediated nucleation (IMN model in which the key physical and chemical parameters are constrained by a variety of recent measurements. Out of roughly 30 nucleation event days sampled during the campaign, four were initially selected on the basis of indications that the observed air masses were relatively homogeneous. It happens that all four of these days exhibited medium to high electrical overcharging of the nucleated nanoparticles. In each of these well-defined cases, reasonable agreement is found between the predictions and field data for a range of variables, including critical nucleation sizes, size-dependent overcharging ratios, and the concentrations of 1.8–3 nm stable clusters and 3–6 nm particles, and their diurnal variations. However, to extend the scope of the study, one case of weak electrical overcharging, and one of clear undercharging, of the nucleated particles were also selected. These electrical states represented less than about 20% of the total event-days recorded, and among this smaller sample there were no days on which the sampled air masses appeared reasonable uniform over the entire nucleation event. Thus, it is perhaps not surprising that the consistency between model simulations and measurements during these more anomalous periods was less satisfying. We tentatively conclude that the outcomes in these cases were influenced by, among other things, the significant variability in the sampled air masses and the possible role of species other than sulfuric acid in the nucleation process. Statistically, roughly 80% of the

    Heterotopic pancreas (HP) is often an incidental finding during operative or endoscopic procedures and described in case reports and small series in the literature. Large clinicopathological studies with a systematic analysis remain lacking. Herein, we identified 184 (0.18%; 184/99 544) consecutive histology-proven HP cases of 89 770 surgical resections and 9774 upper endoscopic biopsies carried out at a single medical center in China. Each case was diagnosed by unequivocal identification of pancreatic acini at a location outside the pancreas. The patients' median age was 49 years (range, 14-82) with a slight female predominance (male/female ratio, 0.94). Clinical presentation at diagnosis was nonspecific. Preoperatively, most (54.9%; 101/184) HP lesions were misdiagnosed. Only 26 HP lesions (14.1%) were correctly diagnosed, all in the stomach except for 1 in the duodenum; 57 (31%) were detected during operative procedures for other conditions. The most frequent location of HP was, in descending order, the stomach (97; 52.7%), small intestine (48; 26%), lesser and greater curvature omentum (18; 10%), spleen and hilar region (5; 2.7%), porta hepatis (2; 1%), gallbladder (1; 0.5%), peridistal esophageal tissue (4; 2.2%), and mesentery (7; 3.8%). The size of HP varied from smaller than 0.5 cm (35.3%), 0.6 to 1 cm (34.8%), to larger than 1.1 cm (29.9%). Because of difficulty in preoperative diagnosis, careful workup for upper gastrointestinal diseases with HP as a differential diagnosis may increase the chance of accurate diagnosis and appropriate patient management.

    AIM: To identify the risk factors for, and to report the microbiological findings and clinical outcomes of, severe microbial keratitis (MK). METHODS: This was a retrospective study of all cases of presumed MK admitted to a tertiary referral center over a 2-year period (September 2001 to August 2003). Data recorded included demographic data, details relating to possible risk factors, results of microbiological studies, clinical findings at presentation, and clinical and visual outcomes. RESULTS: Ninety patients were admitted with a diagnosis of presumed MK during the study period. The mean age of patients was 45 +\\/- 32 years, and the male to female ratio was 47:43 (52.2%:47.7%). Predisposing risk factors for MK included contact lens wear (37; 41.1%), anterior segment disease (19; 21.1%), ocular trauma (13; 14.4%), systemic disease (5; 5.6%), and previous ocular surgery (1; 1.1%). Cultured organisms included gram-negative bacteria (17; 51.5%), gram-positive bacteria (11, 33.3%), acanthamoeba (2; 6.1%), and fungi (1; 3%). Visual acuity improved significantly after treatment [mean best-corrected visual acuity (+\\/-standard deviation) at presentation: 0.76 (+\\/-0.11); mean best-corrected visual acuity at last follow-up: 0.24 (+\\/-0.07); P < 0.001]. Secondary surgical procedures were required in 18 (20%) cases, and these included punctal cautery (1; 1.1%), tissue glue repair of corneal perforation (2; 2.2%), tarsorrhaphy (9; 9.9%), Botulinum toxin-induced ptosis (1; 1.1%), penetrating keratoplasty (3; 3.3%), and evisceration (2; 2.2%). CONCLUSIONS: Contact lens wear remains a significant risk factor for severe MK. MK remains a threat to vision and to the eye, but the majority of cases respond to prompt and appropriate antimicrobial therapy.

  1. Reconstruction of the history of the Galactic Center from X-ray and gamma-ray observations.

    In the centre of our Galaxy lies a super-massive black hole, identified with the radio source Sagittarius A. In this talk I will discuss imaging, spectral, and timing analysis of data from 74 months of observations of the Galactic centre by Fermi/LAT γ-ray telescope complemented by sub-MeV data from approximately ten years of INTEGRAL/PICsIT observations. I will show that the source spectrum is consistent with a model of inverse Compton scattering by high-energy electrons. In this a model, the GeV bump in the spectrum originates from an episode of injection of high-energy particles, which happened ~300 years ago. This injection episode coincides with the known activity episode of the Galactic centre region, previously identified using X-ray observations. This conclusion was derived from the detection of reflected X-ray emission from the giant molecular clouds in the Galactic centre region. However, the interpretation of the reflected emission spectra cannot be done correctly without detailed modelling of the reflection process. I will also discuss the Monte Carlo simulation code in we have developed to fully model the complex processes involved in the emerging reflection spectra. Application of our code to XMM-Newton, Chandra and INTERGRAL observations of Sgr B2, alow us to constrain the position and density of the cloud and the incident luminosity of the central source.

    Ventricular septal rupture (VSR) is a rare but devastating complication after acute myocardial infarction (AMI). While the incidence has decreased, the mortality rate from VSR has remained extremely high. The use of mechanical circulatory support with intra-aortic balloon pump (IABP) and extracorporal membrane oxygenation (ECMO) may be useful in providing hemodynamic stability and time for myocardial scarring. However, the optimal timing for surgical repair remains an enigma. Retrospective analysis of 14 consecutive patients diagnosed with VSR after AMI at Montefiore Medical Center between January 2009 and June 2015. A chart review was performed with analysis of baseline characteristics, hemodynamics, imaging, percutaneous interventions, surgical timing, and outcomes. The survival group had a higher systolic BP (145 vs 98, p<0.01), higher MAP (96 vs 76, p=0.03), and lower HR (75 vs 104, p=0.05). Overall surgical timing was 6.5 ± 3.7 days after indexed myocardial infarction with a significant difference between survivors and non-survivors (9.8 vs 4.3, p=0.01). The number of pre-operative days using IABP was longer in survivors (6.5 vs 3.2, p=0.36) as was post-operative ECMO use (4.5 vs 2 days, p=0.35). The overall 30-day mortality was 71.4% with a 60% surgical mortality rate. Hemodynamics at the time of presentation and a delayed surgical approach of at least 9 days showed significant association with improved survival. Percutaneous coronary intervention (PCI) was more common in non-survivors. The use of IABP in the pre-operative period and post-operative ECMO use likely provide a survival benefit. PMID:27073732

    Pulsar wind nebulae (PWNe) provide unique opportunities to study relativistic pulsar winds and their interaction with the surrounding medium. G63.7+1.1 is an intriguing supernova remnant studied so far only at radio wavelengths and classified as a PWN candidate based on its nonthermal radio emission. We present the first X-ray study of G63.7+1.1, obtained with XMM-Newton and the Chandra X-ray Observatory, with the goal of detecting and studying the candidate PWN in X-rays and searching for the neutron star candidate. The peak of the X-ray emission lies approximately 1.‧2 from the peak of the 21 cm continuum emission and is offset from the center of the X-ray nebula. The diffuse X-ray emission is irregularly shaped (4.‧2 × 3.‧2), unlike the nearly symmetric 8‧-diameter radio nebula. Its X-ray spectrum is fit with a power-law model, yielding a photon index of {1.75}-0.3+0.4, a column density of (1.6 ± 0.5) × 1022 cm‑2, and an X-ray luminosity of ∼2 × 1033 erg s‑1 (0.5–10.0 keV) at a kinematic distance of 6 kpc. Several point-like sources were detected within the limit of the X-ray nebula. We present a study of their spectra, identifying 3XMM J194753.4+274357 (CXO J194753.3+274351) as a candidate for the location of the neutron star powering the nebula. Located in a dense environment, we estimate that G63.7+1.1 is old enough (≥8 kyr) for the reverse shock to have interacted with the PWN. This, together with the large size estimated from radio studies (∼14 pc) and the offset between the radio and X-ray peaks, suggests an evolved nebula, with the radio nebula being a “relic” PWN.

    Project management education programmes are often proposed in higher education to give students competences in project planning (Gantt's chart), project organizing, human and technical resource management, quality control and also social competences (collaboration, communication), emotional ones (empathy, consideration of the other, humour, ethics), and organizational ones (leadership, political vision, and so on). This training is often given according a training-by-project type of learning with case studies. This article presents one course characterized by a pedagogical organization based upon Knowledge Management (KM) concepts: knowledge transfer and construction throughout a learning circle and social interactions. The course is supported by a rich and complex tutor organization. We have observed this course by using another KM method inspired from KADS with various return of experience formalized into cards and charts. Our intention is, according to the model of Argyris and Sch\\"on (Smith, 2001), to gai...

    2007-01-01

    One of the recommendations of the Decadal Survey that was recently released by the National Academy of Science was that of a geostationary platform from which to obtain trace gas measurements. The use of such a platform is particularly advantageous when applied to understanding the formation of regional air pollution. This study demonstrates the challenges of trying to utilize information from instruments on satellites in low-earth orbit (LEO). We also demonstrate the advantage gained through a simulation that would provide hourly observations. In this case study, we take advantage of the high resolution Level-2 orbital data available from the Ozone Monitoring Instrument (OMI), in conjunction with assimilated stratospheric column ozone fields, to evaluate if meaningful tropospheric ozone information can be obtained on a regional scale. We focus on a period on late June 2005 when a widespread pollution episode enveloped the Houston metropolitan area as well as a large region in southeast Texas.

    We have created 0.3-10 keV, 13 yr, unabsorbed luminosity lightcurves for 528 X-ray sources in the central 20' of M31. We have 174 Chandra observations spaced at ∼1 month intervals due to our transient monitoring program, deeper observations of the M31 nucleus, and some public data from other surveys. We created 0.5-4.5 keV structure functions (SFs) for each source for comparison with the ensemble SF of active galactic nuclei (AGN). We find 220 X-ray sources with luminosities ≳10{sup 35} erg s{sup –1} that have SFs with significantly more variability than the ensemble AGN SF, and which are likely X-ray binaries (XBs). A further 30 X-ray sources were identified as XBs using other methods. We therefore have 250 probable XBs in total, including ∼200 new identifications. This result represents great progress over the ∼50 XBs and ∼40 XB candidates previously identified out of the ∼2000 X-ray sources within the D {sub 25} region of M31; it also demonstrates the power of SF analysis for identifying XBs in external galaxies. We also identify a new transient black hole candidate, associated with the M31 globular cluster B128.

    The study was conducted on six watersheds ranging in size from 277 km to 3460 km in the Rio Grande and Arkansas River basins of southwestern Colorado. Six years of satellite data in the period 1973-78 were analyzed and snowcover maps prepared for all available image dates. Seven snowmapping techniques were explored; the photointerpretative method was selected as the most accurate. Three schemes to forecast snowmelt runoff employing satellite snowcover observations were investigated. They included a conceptual hydrologic model, a statistical model, and a graphical method. A reduction of 10% in the current average forecast error is estimated when snowcover data in snowmelt runoff forecasting is shown to be extremely promising. Inability to obtain repetitive coverage due to the 18 day cycle of LANDSAT, the occurrence of cloud cover and slow image delivery are obstacles to the immediate implementation of satellite derived snowcover in operational streamflow forecasting programs.

    Implantable cardioverter defibrillator (ICD) lead insulation failure and conductor externalization have been increasingly reported. The 7.8F silicon-insulated Linox SD and Linox S ICD leads (Biotronik, Berlin, Germany) were released in 2006 and 2007, respectively, with an estimated 85,000 implantations worldwide. A 39-year-old female suffered an out-of-hospital ventricular fibrillation (VF) arrest with successful resuscitation. An ICD was implanted utilizing a single coil active fixation Linox(Smart) S lead (Biotronik, Berlin, Germany). A device-triggered alert approximately 3 years after implantation confirmed nonphysiological high rate sensing leading to VF detection. A chest X-ray showed an abnormality of the ICD lead and fluoroscopic screening confirmed conductor externalization proximal to the defibrillator coil. In view of the combined electrical and fluoroscopic abnormalities, urgent lead extraction and replacement were performed. A review of Linox (Biotronik) and Vigila (Sorin Group, Milan, Italy) lead implantations within our center (n = 98) identified 3 additional patients presenting with premature lead failure, 2 associated with nonphysiological sensed events and one associated with a significant decrease in lead impedance. All leads were subsequently removed and replaced. This case provides a striking example of insulation failure affecting the Linox ICD lead and, we believe, is the first to demonstrate conductor externalization manifesting both electrical and fluoroscopic abnormalities.

    Full Text Available With the entrepreneurship mission incorporated into the education and research missions of universities, their role in the economic and social development in societies has increased. Thus, subjects revolving around academic entrepreneurship and knowledge commercialization have drawn the attention of many researchers and politicians in different countries in the world. In Iran, too, the knowledge commercialization phenomenon is in its prime and is in its early stages of taking shape and development. Therefore, this paper aims to identify obstacles and solutions in the commercialization of university research in Iran. The qualitative research method has been used in the form of a case study. The research data collection tools consist of semi-structured interviews. As a compliment of data collection tools, some evidence and documents were also studies. The research statistical population includes all the individuals engaged in knowledge commercialization in the University of Tehran. Twenty six interviews were conducted before data saturation reached. The results of the qualitative research indicate that the organizational, environmental/institutional and internal university research commercialization impeding factors are critical obstacles in the Small Business Development Center (SBDC of the University of Tehran and policy makers should devise proper strategies in light of these factors.

    Materials and Methods: A case-controlled study of fifty newly-admitted patients at King Faisal Specialist Hospital & Research Center, Riyadh, Saudi Arabia diagnosed with colorectal cancer were interviewed to collect data on various dietary factors and their nutritional status. Their data were compared with a sex-matched control group aged fifty. Results: The consumption of meat high in fat, fried eggs and whole fat dairy products, and diet low in fibers 2-3 times or above per week increased the risk of colorectal cancer, while the consumption of whole wheat products, vegetables and fruits, and diet low in animal fats at the same rate per week may play a protective role against colorectal cancer in both men and women when compared to controls. Conclusions: The higher consumption of meat and fat from animal sources could increase the risk of colorectal cancer. The high consumption of whole wheat bread, fruits and vegetables with high fiber content could play a protective role against the risk of colorectal cancer in the Saudi society. Additional studies are needed in different regions of the Kingdom of Saudi Arabia to verify or refute these results.

    2005-05-01

    The main aim of this article is to examine and review the usage of forests for the purpose of tourism in Turkey with the case study of Antalya-Belek. The use and conversion of forest lands is central to tourism development. Land use change is responsible for the majority of the negative environmental impacts of tourism on natural resources. Worldwide, forests and coastal zones are converted for the construction of tourist facilities. The rapid emergence of mass tourism development in Turkey, encouraged without considering protection and sustainable use of natural and cultural resources, has resulted in serious problems in forest areas. This paper is particularly concerned with land use change in forests (or deforestation) created by the allocation of forest lands to build tourist facilities. In Belek, a tourism center located in Antalya province's coastal areas and the fastest growing destination of the country, all tourist facilities have been established in forest lands under the status of conservation forest. Today, the Belek Conservation Forest is under severe pressure from tourism. PMID:15829368

    The aim is to show that in case of low probability of asteroid collision with Earth, the appropriate selection and weighing of the data are crucial for the impact investigation, and to analyze the impact possibilities using extensive numerical simulations. By means of the Monte Carlo special method a large number of ``clone'' orbits have been generated. A full range of orbital elements in the 6-dimensional parameter space, e.g. in the entire confidence region allowed by the observational material has been examined. On the basis of 1000 astrometric observations of (99942) Apophis, the best solution for the geocentric encounter distance of 6.065\\pm 0.081 R_{Earth} were derived for the close encounter with the Earth on April 13, 2029. The present uncertainties allow for the special configurations (``keyholes'') during these encounter which may lead to the very close encounters in the future approaches of Apophis. Two groups of keyholes are connected with the close encounter with the Earth in 2036 (within the min...

    Summertime photochemical air pollution episodes within the United Kingdom have been proposed via modelling studies to be strongly influenced by regional scale inflow of air from the continental European boundary layer. We present a vertically resolved case study using measurements made from the NERC/Met Office BAe 146 research aircraft on 18th August 2005 over the South East of England and the North Sea during a weak anticyclone centred over Northern Europe. The vertical distribution of ozone, CO, NO(x), peroxyacetyl nitrate (PAN) and a wide range of both nonmethane hydrocarbons (NMHC) and oxygenated volatile organic compounds (OVOCs) were determined between 500 ft (approximately 152 m) and 7000 ft (approximately 2134 m) over the East Anglia coastline and 50 km inland. In excess of 80 ppbV ozone was observed within inflowing boundary layer air over the North Sea coast in a broad N-S sloping feature around 60 km wide. The inflowing feature of European origin was also observed further inland within the boundary layer albeit with lower, more variable, ozone mixing ratios. The increased variability in ozone over land was a product of titration by fresh surface emissions of NO via rapid upward transport in thermals, a hypothesis supported by the observed vertical wind speed component. Fast boundary layer mixing over land was further illustrated by a uniform distribution in reactive alkenes. A comparison between aircraft and surface O(3) UK AUN (Automatic Urban Network) measurements showed good agreement with the inland site, Sibton, but marked differences with the coastal monitoring site at Weybourne, potentially due to gradients established by ocean deposition in stably stratified marine air.

    Full Text Available Guillain-Barré Syndrome (GBS can be triggered by gastrointestinal or respiratory infections, including influenza. During the 2009 influenza A (H1N1 pandemic in the United States, monovalent inactivated influenza vaccine (MIV availability coincided with high rates of wildtype influenza infections. Several prior studies suggested an elevated GBS risk following MIV, but adjustment for antecedent infection was limited.We identified patients enrolled in health plans participating in the Vaccine Safety Datalink and diagnosed with GBS from July 2009 through June 2011. Medical records of GBS cases with 2009-10 MIV, 2010-11 trivalent inactivated influenza vaccine (TIV, and/or a medically-attended respiratory or gastrointestinal infection in the 1 through 141 days prior to GBS diagnosis were reviewed and classified according to Brighton Collaboration criteria for diagnostic certainty. Using a case-centered design, logistic regression models adjusted for patient-level time-varying sources of confounding, including seasonal vaccinations and infections in GBS cases and population-level controls.Eighteen confirmed GBS cases received vaccination in the 6 weeks preceding onset, among 1.27 million 2009-10 MIV recipients and 2.80 million 2010-11 TIV recipients. Forty-four confirmed GBS cases had infection in the 6 weeks preceding onset, among 3.77 million patients diagnosed with medically-attended infection. The observed-versus-expected odds that 2009-10 MIV/2010-11 TIV was received in the 6 weeks preceding GBS onset was odds ratio = 1.54, 95% confidence interval (CI, 0.59-3.99; risk difference = 0.93 per million doses, 95% CI, -0.71-5.16. The association between GBS and medically-attended infection was: odds ratio = 7.73, 95% CI, 3.60-16.61; risk difference = 11.62 per million infected patients, 95% CI, 4.49-26.94. These findings were consistent in sensitivity analyses using alternative infection definitions and risk intervals for prior

    The Fermi Bubbles are a pair of giant lobes at the heart of the Milky Way, extending roughly 50 degrees north and south of the Galactic Center, and emitting photons with energies up to 100 GeV. This previously unknown structure could be evidence for past activity of the central supermassive black hole, or enhanced star formation towards the inner Galaxy. I will describe the most updated microwave observations from joint analysis with WMAP and Planck, and their shape and spectrum using most updated gamma-ray data from the Fermi Gamma-ray Space Telescope and dedicated observations with XMM-Newton. We will describe the current state of knowledge of the Bubbles’ spectrum, morphology and internal structure, and discuss theoretical proposals and numerical simulations for their nature and origin.

    The Precious Stone Mountain hydrothermal field (PSMHF) is located on the southern rim of the Galapagos Microplate. It was found at the 3rd leg of the 2009 Chinese DY115-21 expedition on board R/V Dayangyihao. It is efficient to learn the distribution of hydrothermal plumes and locate the hydrothermal vents by detecting the anomalies of turbidity and temperature. Detecting seawater turbidity by MAPR based on deep-tow technology is established and improved during our cruises. We collected data recorded by MAPR and information from geological sampling, yielding the following results: (1)Strong hydrothermal turbidity and temperature anomalies were recorded at 1.23°N, southeast and northwest of PSMHF. According to the CTD data on the mooring system, significant temperature anomalies were observed over PSMHF at the depth of 1,470 m, with anomalies range from 0.2℃ to 0.4℃, which gave another evidence of the existence of hydrothermal plume. (2)At 1.23°N (101.4802°W/1.2305°N), the nose-shaped particle plume was concentrated at a depth interval of 1,400-1,600 m, with 200 m thickness and an east-west diffusion range of 500 m. The maximum turbidity anomaly (0.045 △NTU) was recorded at the depth of 1,500 m, while the background anomaly was about 0.01△NTU. A distinct temperature anomaly was also detected at the seafloor near 1.23°N. Deep-tow camera showed the area was piled up by hydrothermal sulfide sediments. (3) In the southeast (101.49°W/1.21°N), the thickness of hydrothermal plume was 300 m and it was spreading laterally at a depth of 1,500-1,800 m, for a distance about 800 m. The maximum turbidity anomaly of nose-shaped plume is about 0.04 △NTU at the depth of 1,600 m. Distinct temperature anomaly was also detected in the northwest (101.515°W/1.235°N). (4) Terrain and bottom current were the main factors controlling the distribution of hydrothermal plume. Different from the distribution of hydrothermal plumes on the mid-ocean ridges, which was mostly

Background: Myxomas are benign neoplasms which can be found within large muscle groups. Histologically, these neoplasms are composed of a few elongated or star-shaped cells lying in abundant mucoid stroma. These tumours are characterized by expanding growth without forming distant metastases. Case description: A man, 58, came to the Surgical Oncology Outpatient Clinic due to pain ailments and a growing tumour located in the rear group of the left shank muscles. The patient had been observing the lesion for several years, but related the occurrence of pain to the change in the nature of his job - from sedentary to standing. The patient underwent diagnostic imaging, a magnetic resonance imaging test, in which a tumour was described. A surgery was carried out where the tumour was resected together with the lateral head of the gastrocnemius muscle. No significant walking disorders, neurological deficits, either sensory or motor were observed. The follow-up imaging examinations, which were carried out a year after the surgery, did not reveal a relapse. The patient remains under the care of the Surgical Oncology Outpatient Clinic. Conclusion: Myxomas are a group of benign neoplasms whose first symptom is the appearance of a palpable tumour whose stretching growth causes painful ailments. After magnetic resonance imaging and a diagnosis, it is necessary to plan the surgery. Radical resection of the lesion is a method of choice which guarantees long-lasting recovery. (authors)

    AIM: To analyze 67 cases of splenic abscess in a medical center of Taiwan during a period of 19 years.METHODS: From January 1986 to December 2004, a total of 67 patients with splenic abscess were enrolled for the retrospective study. The clinical characteristics,underlying diseases, organism spectra, therapeutic methods, APACHE Ⅱ scores, and mortality rates were analyzed.RESULTS: There were 41 males and 26 females with the mean age of 54.1± 14.1 years. Multiple splenic abscesses (MSA) account for 28.4% and solitary splenic abscess in 71.6% of the patients. Twenty-six of sixtyseven patients (35.8%) had extrasplenic abscesses, with leading site of liver (34.6%). Microbiological cultures were positive in 58 patients (86.6%), with 71.8% in blood culture and 93.5% in abscess culture. Gram negative bacillus (GNB) infection predominated (55.2%),with leading pathogen ofKlebsiella pneumoniae (22.4%),followed by gram positive coccus (GPC) infection (31%).Splenectomy was performed in 26 patients (38.8%),percutaneous drainage or aspiration in 21 (31.3%),and antibiotic therapy alone in 20 patients (29.9%).Eventually, 12 of 67 patients expired (17.9 %). By statistics, spleen infected with GNB was likely to develop multiple abscesses compared with infection with GPC(P=0.036). Patients with GNB infection (P= 0.009) andmultiple abscesses (P= 0.011) experienced a higher mortality rate than patients with GPC infection and solitary abscess. The mean APACHE Ⅱ score of 12 expired patients (16.3 ±3.2) was significantly higher than that of the 55 survivals (7.2 ± 3.8) (P< 0.001).CONCLUSION: MSA, GNB infection, and high APACHEⅡ scores are poor prognostic factors. Early surgical intervention should be encouraged when these risk factors are present.

    Full Text Available Rosai-Dorfman disease (RDD is a nonmalignant histiocytic disorder of unknown origin that is extremely rare. By immunohistochemistry, the RDD cells are characteristically S-100 positive and CD1a negative. Emperipolesis is a common histopathological finding, although not specific for RDD. Lymph node and cutaneous manifestations are most frequent, but diverse organs can be affected. The clinical course is unpredictable regardless of treatment. Here, we present a series of 8 cases presenting lymph node and/or cutaneous lesions. Lymph node involvement was seen in diverse regions, including mediastinal and retroperitoneal. The treatment response to steroids was diversified, and the chemotherapy response was disappointing. Associated autoimmune diseases (Sjögren syndrome and antiphospholipid syndrome were observed in 2 patients. Regardless of therapy modality, these patients exhibited a favorable prognosis in a follow-up duration that ranged from 15 to 80 months.

    Full Text Available Abstract This report describes a case of rectal cancer with endoscopically observable white nodules caused by distal intramural lymphatic spread. A 57-year-old female presented to our hospital with frequent diarrhea and hemorrhoids. Computed tomography showed bilateral ovarian masses and three hepatic tumors diagnosed as rectal cancer metastases, and also showed multiple lymph node involvement. The patient was preoperatively diagnosed with stage IV rectal cancer. Colonoscopy demonstrated that primary rectal cancer existed 15 cm from the anal verge and that there were multiple white small nodules on the anal side of the primary tumor extending to the dentate line. Biopsies of the white spots were performed, and they were identified as adenocarcinoma. The patient underwent Hartmann’s procedure because of the locally advanced primary tumor. The white nodules were ultimately diagnosed as being caused by intramural lymphatic spreading because lymphatic permeation was strongly positive at the surrounding area. Small white nodules near a primary rectal cancer should be suspected of being intramural spreading. Endoscopic detection of white nodules may be useful for the diagnosis of distal intramural spread.

    Breast cancer is the most common type of non-skin cancer in women. 2D mammography is a screening tool to aid in the early detection of breast cancer, but has diagnostic limitations of overlapping tissues, especially in dense breasts. 3D mammography has the potential to improve detection outcomes by increasing specificity, and a new 3D screening tool with a 3D display for mammography aims to improve performance and efficiency as compared to 2D mammography. An observer study using human studies collected from was performed to compare traditional 2D mammography with this new 3D mammography technique. A prior study using a mammography phantom revealed no difference in calcification detection, but improved mass detection in 2D as compared to 3D. There was a significant decrease in reading time for masses, calcifications, and normals in 3D compared to 2D, however, as well as more favorable confidence levels in reading normal cases. Data for this current study is currently being obtained, and a full report should be available in the next few weeks.

    We present a study of a typical explosive event (EE) at subarcsecond scale witnessed by strong non-Gaussian profiles with blue- and redshifted emission of up to 150 km s{sup –1} seen in the transition region Si IV 1402.8 Å, and the chromospheric Mg II k 2796.4 Å and C II 1334.5 Å observed by the Interface Region Imaging Spectrograph (IRIS) at unprecedented spatial and spectral resolution. For the first time an EE is found to be associated with very small-scale (∼120 km wide) plasma ejection followed by retraction in the chromosphere. These small-scale jets originate from a compact bright-point-like structure of ∼1.''5 size as seen in the IRIS 1330 Å images. SDO/AIA and SDO/HMI co-observations show that the EE lies in the footpoint of a complex loop-like brightening system. The EE is detected in the higher temperature channels of AIA 171 Å, 193 Å, and 131 Å, suggesting that it reaches a higher temperature of log T = 5.36 ± 0.06 (K). Brightenings observed in the AIA channels with durations 90-120 s are probably caused by the plasma ejections seen in the chromosphere. The wings of the C II line behave in a similar manner to the Si IV'S, indicating close formation temperatures, while the Mg II k wings show additional Doppler-shifted emission. Magnetic convergence or emergence followed by cancellation at a rate of 5 × 10{sup 14} Mx s{sup –1} is associated with the EE region. The combined changes of the locations and the flux of different magnetic patches suggest that magnetic reconnection must have taken place. Our results challenge several theories put forward in the past to explain non-Gaussian line profiles, i.e., EEs. Our case study on its own, however, cannot reject these theories; thus, further in-depth studies on the phenomena producing EEs are required.

  16. Monitoring soil wetness variations by means of satellite passive microwave observations: the HYDROPTIMET study cases

    . This analysis allows us to evaluate the reliability and the efficiency of the proposed technique in identifying different amounts of soil wetness variations in different observational conditions. In particular, the proposed indicator was able to document the actual effects of meteorological events, in terms of space-time evolution of soil wetness changes, for all the analysed HYDROPTIMET test cases. Moreover, in some circumstances, the SWVI was able to identify the presence of a sort of 'early' signal in terms of soil wetness variations, which may be regarded as a timely indication of an anomalous value of soil water content. This evidence suggests the opportunity to use such an index in the pre-operational phases of the modern flood warning systems, in order to improve their forecast capabilities and their reliability.

    Full Text Available "nCoronary artery bypass grafting (CABG surgery is being performed increasingly in Iran. So far, no large-scale report has described characteristics and risk factor profile and in-hospital mortality of patients undergoing this procedure in Iran. We conducted this study to address these topics in order to help clarify Iran's current state of CABG and to provide assistance in planning combat against coronary artery disease based on frequency of major risk factors. Patients who underwent isolated, first-time, elective, on-pump (conventional CABG in a cardiac surgery center in Tehran were prospectively studied from September 2004 and March 2005. Demographic data, risk factor profile and discharge status for each patient were recorded. There were 1258 patients, 937 men (74.5% and 321 women (25.5%. The mean age was 58.7 years (range 28 to 81; 133 patients (10.6% were 70 years old or older. Mean body mass index (BMI was 27.01 and 42.2% of the patients were smokers, 39.4% were hypertensive, and 27.6% had diabetes. Family history was positive in 40.3%. Congestive heart failure was found in 26.6%. New York Heart Association functional class III or IV was observed in 52.8% of patients. Single-vessel, two-vessel, and multi-vessel disease was found in 4.2%, 21.1%, and 74.7% of patients, respectively. Left main was involved in 9.8% and 14.4% had ejection fraction < 35%. The in-hospital mortality was 1.5%, mainly due to cardiac causes. This study indicates significant prevalence of major cardiovascular risk factors in Iranian CABG patients. In-hospital mortality of primary isolated CABG in Iran is similar to reported rates.

  19. Dust-grain scattering of X-rays observed during the lunar occultation of a transient X-ray source near the Galactic center

    International Nuclear Information System (INIS)

    Extended X-ray emission surrounding point X-ray sources has been detected in the energy band 1-10 keV during lunar occultation observations of the Galactic center region. These extended X-rays are most likely due to X-ray scattering by interstellar dust grains. The spatial size and the intensity of the extended emission around the transient X-ray source GS 1741.2-2859/1741.6-2849 have been studied extensively. The spatial size is consistent with the typical grain size of about 0.06 micron. The intensity is used to obtain the energy dependence of the scattering optical depth to the source, which suggests the existence of iron in the grains. The ratio of the iron column density contained in the grains to the hydrogen column density of the neutral gas is roughly consistent with the cosmic abundance of iron. 30 refs

    CERN Document Server

    Yusef-Zadeh, F; Geballe, T R

    2005-01-01

    The Trifid nebula (M20) is a well-known prominent optical HII region trisected by bands of obscuring dust lanes and excited by an O7.5 star HD 164492A. Previous near-IR, mid-IR and radio continuum observations of the cluster of stars at the center of the Trifid nebula indicated circumstellar disks associated with hot stars with envelopes that are photoionized externally by the UV radiation from the hot central star, HD 164492A. Using WFPC2 of the HST, we present evidence of a resolved proplyd in H$\\alpha$ and [SII] line emission from a stellar source emitting cool dust emission. Using UKIRT, an infrared observation of the stellar source with a proplyd indicates a late F -- mid G spectral type. We also note a remarkable complex of filamentary and sheet-like structures which appear to arise from the edge of a protostellar condensation. These observations are consistent with a picture in which the bright massive star HD 164492A is responsible for the photoevaporation of protoplanetary disks of other less-massive...

    I develop a concept of observability that pertains to qualities rather than objects: A quality is observable if it can be registered by human sensation (possibly with the aid of instruments) without involving optional interpretations. This concept supports a better description of observations in science and everyday life than the object-based observability concepts presupposing causal information-transfer from the object to the observer. It also allows a rehabilitation of the traditional empi...

  3. Regular observation of natural background radiation in high school using a ventilated case for meteorological instruments

    International Nuclear Information System (INIS)

    There are many examples of the measurement of natural background radiation in schools. Most schools in Japan have ventilated cases for taking meteorological measurements, but they are rarely used. We measure natural background radiation using a ventilated case as part of chemistry club activities. Figures 2 and 3 to 6 show the natural background radiation in various rooms, and in the ventilated case, respectively. I propose that there are some advantages to using ventilated meteorological station cases for the measurement of natural background radiation. (author)

    The aerosol index (AI) from the Total Ozone Mapping Spectrometer (TOMS) satellite and meteorological parameters from National Center for Environmental Prediction and the National Center for Atmospheric Research (NCEP/NCAR) reanalysis datasets were used to examine seasonal dust cases in northern Saudi Arabia. Considering all seasons, winter has the fewest dust cases, whereas summer has the most dust cases. Synoptically, surface high-pressure systems in the eastern and western regions are important for the occurrence of dust cases over the northern Arabian Peninsula. When the eastern high pressure prevails, the effects of the Indian low-pressure system on the Arabian Peninsula are weakened or become nonexistent. The extension of the western high-pressure system toward the southeast provides an opportunity for a low-pressure system over Southeast Africa to connect with the Indian low-pressure system, which increases the width of the low-pressure trough and affects the Arabian Peninsula by increasing the amount of dust over the region. At 850 hPa, the weather systems typically rotate clockwise between winter and autumn. In winter, cyclonic systems prevail in the northern region, while anticyclonic systems prevail in the south. The systems are oriented toward the northeast in spring, the west in summer, and the southeast in autumn. Moreover, northern cyclones at 500 hPa shrink as they move northward and the maximum wind speed at 250 hPa decreases from winter to summer. Furthermore, the case study confirms that a change in the relative strength of the pressure systems and a change in the orientation of the isobars (contours) affect the amount of dust over the area. When the orientation of the isobar (contour) lines become strictly north to south or east to west, the amount of dust decreases and vice versa.

    The authors report 136 cases of spondylodiscitis due to ordinary organisms seen between 1980 and 1989 and note the increasing incidence of iatrogenic forms which during the past three years accounted for 50 per cent of cases. 60 per cent of these cases of iatrogenic spondylodiscitis complicated a medical of surgical procedure involving the spine (form by direct inoculation). In 40 per cent of cases, the organism came from a site of infection located at a distance (from by blood-borne spread). The clinical picture in cases of primary spondylodiscitis and of iatrogenic disease by blood-borne spread is essentially similar. That of iatrogenic forms by direct inoculation is different: most often young subjects, virtually exclusive involvement of the lumbar spine, fever and inflammatory syndrome less common. Escherichia coli and Staphylococcus aureus were the organisms most often responsible for primary spondylodiscitis (23 and 21.7 per cent of case respectively). Streptococci were in third position only (15.6 per cent of cases). Staphylococcus aureus remained predominant in iatrogenic spondylodiscitis (34 per cent of cases), while Escherichia coli and streptococci were significantly rarer than in primary forms and there was the appearance of Pseudomonas aeruginosa and Staphylococcus albus. No organism was found in 23 per cent of cases of primary spondylodiscitis. This figure reached 44% of iatrogenic forms by direct inoculation. Because of their increasing incidence, these cases of apparently aseptic spondylodiscitis, frequently complicating a procedure involving the spine, are modifying the picture of infectious spondylodiscitis. No doubt worthy of separate identification, they raise the problem of the significance of the concept of aseptic spondylodiscitis. PMID:1780664

  8. Results from a Case Study Investigation on the Adoption of Learner-Centered Strategies in Introductory Astronomy

    Science.gov (United States)

    Bailey, Janelle M.; Nagamine, K.

    2008-05-01

    Recent research in science education suggests that learner-centered instructional strategies can promote more learning than traditional teacher-based strategies such as lecture. However, the adoption of such strategies by instructors can elicit many concerns, including, for example, concerns of increased time requirements for preparation and grading, reduced content coverage, reactions of students and colleagues, and, of course, student achievement. Ethan, an astronomy instructor early in his career, recently adopted learner-centered strategies into his introductory course for nonscience majors on stars and galaxies. He shared the concerns listed above, but after receiving training in learner-centered strategies from the Center for Astronomy Education and support from an experienced colleague while implementing the changes for the first time, Ethan's overall reaction was a positive one. Although the preparation time was somewhat higher than would have been required had he repeated his previous semester, Ethan felt that it was worth it to move away from lecture-only style and to incorporate learner-centered strategies into his course. For him, it simply felt more gratifying when he walked out of the classroom after using learner-centered methods than it had when he used only lecture. He also felt that many students learned more than those in previous lecture-based course offerings, and that their increased active participation during the class was a constructive change. In fact, average exam scores were comparable or higher than two previous semesters, as were student evaluations. Overall, Ethan felt that the integration of learner-centered strategies was well worth the time and effort, as evidenced by his statement, "I'll never go back to lecture-only again!" This project is supported by the University of Nevada, Las Vegas Division of Research and Graduate Studies.

  10. Observation and studies of jet quenching in PbPb collisions at nucleon-nucleon center-of-mass energy = 2.76 TeV

    Energy Technology Data Exchange (ETDEWEB)

    2011-08-01

    Jet production in PbPb collisions at a nucleon-nucleon center-of-mass energy of 2.76 TeV was studied with the CMS detector at the LHC, using a data sample corresponding to an integrated luminosity of 6.7 inverse microbarns. Jets are reconstructed using the energy deposited in the CMS calorimeters and studied as a function of collision centrality. With increasing collision centrality, a striking imbalance in dijet transverse momentum is observed, consistent with jet quenching. The observed effect extends from the lower cut-off used in this study (jet transverse momentum = 120 GeV/c) up to the statistical limit of the available data sample (jet transverse momentum approximately 210 GeV/c). Correlations of charged particle tracks with jets indicate that the momentum imbalance is accompanied by a softening of the fragmentation pattern of the second most energetic, away-side jet.

    Full Text Available OBJECTIVES. The aim of this study was to quantify the level of health related quality of life and burnout in a call centers sample of precarious workers. METHODS. An observational study was carried out in Italy. A self-reported anonymous questionnaire was administered to temporary workers in order to estimate burn-out and quality of life levels. RESULTS. 227 questionnaires were collected. 78% of the sample was female and the mean age was 35.48 years (SD = 9.91. Among the participants, 40% were smokers, 42% regularly drinkers, 65% changed the body weight (more than 5 kg, in 1 year. The mental component score (MCS was significantly better in subject that have a regularly life style, for example in those no change their body weight (p = 0.001, sleep more than 7 hours (p = 0.018 and followed a diet (p = 0.035. The DP (depersonalization is significant higher in former smokers (p = 0.031, in underweight subjects (p = 0.025 and in the group that have a precarious employment of over 2 years (p = 0.013. CONCLUSIONS. This investigation shows that in this particular category of atypical workers depressive symptoms and quality of life were lower than the general population. It is important to underline that the interpretation of the results is limited partly by the observational character of the study.

  12. Observation of the intermediate vector bosons W+- and Z0 in proton-antiproton collisions at 546 GeV center of mass energy. UA2 experiment

    International Nuclear Information System (INIS)

    The Standard Model of electromagnetic and weak interactions predicts the existence of the intermediate vector bosons W+- and Z0 and gives precise predictions for their masses. Antiproton accumulation by stochastic cooling and the operation of the CERN SPS accelerator in collider mode made accessible pantip at 546 GeV center of mass energy. This thesis presents the observation of the intermediate vector bosons through their decays Z0 → e+e-, W → eν. During running periods 1982 and 1983, 8 decays Z0 → e+e- and 32 decays W → eν with an electron of Psub(T) > 25 GeV/c were observed in UA2 experiment. Cross sections of W+- and Z0 production and the weak interaction parameters: Msub(W), Msub(Z), sin2thetasub(W) and rho are determined. These results are in agreement with Standard Model predictions, thus confirming theory in a spectacular way. An upper limit to the total width of the Z0 is given. An upper limit to the number of additional neutrinos is inferred. Radiative decays of the intermediate vector bosons are discussed

    1090 cases of child epilepsy were divided randomly into two groups: the treatment group (930 cases treated with anti-epilepsy capsules) and the control group (160 cases treated with luminal). The results showed that in the treatment group, 534 cases were markedly effective, 241 effective, 96 improved, 46 ineffective, and 13 aggravated, with a total effective rate of 83.33%; while in the control group, 64 cases were markedly effective, 19 effective, 38 improved, 29 ineffective, and 10 aggravated, with a total effective rate of 51.88%. The treatment group showed an obviously higher total effective rate than that in the control group (P<0.01). After treatment, cases in the two groups all had lower frequency of epilepsy attacks and shorter duration of each attack as compared with that before treatment (P<0.01), but the situation was obviously better in the treatment group. The anti-epilepsy capsules had very good effect on various types of epilepsy, especially on autonomic epilepsy and on epilepsies due to wind, phlegm, or terror as differentiated in TCM. After treatment, the recovery rate shown by EEG examination was 54.3% in the treatment group, while 38.4% in the control group, the former being obviously higher than the latter (P<0.01).

    2006-12-01

    Full Text Available Abstract Background Population impact measures (PIMs have been developed as tools to help policy-makers with locally relevant decisions over health risks and benefits. This involves estimating and prioritising potential benefits of interventions in specific populations. Using tuberculosis (TB in India as an example, we examined the population impact of two interventions: direct observation of therapy and increasing case-finding. Methods PIMs were calculated using published literature and national data for India, and applied to a notional population of 100 000 people. Data included the incidence or prevalence of smear-positive TB and the relative risk reduction from increasing case finding and the use of direct observation of therapy (applied to the baseline risks over the next year, and the incremental proportion of the population eligible for the proposed interventions. Results In a population of 100 000 people in India, the directly observed component of the Directly Observed Treatment, Short-course (DOTS programme may prevent 0.188 deaths from TB in the next year compared with 1.79 deaths by increasing TB case finding. The costs of direct observation are (in international dollars I$5960 and of case finding are I$4839 or I$31702 and I$2703 per life saved respectively. Conclusion Increasing case-finding for TB will save nearly 10 times more lives than will the use of the directly observed component of DOTS in India, at a smaller cost per life saved. The demonstration of the population impact, using simple and explicit numbers, may be of value to policy-makers as they prioritise interventions for their populations.

    Causal inference in observational studies is notoriously difficult, due to the fact that the experimenter is not in charge of the treatment assignment mechanism. Many potential con- founding factors (PCFs) exist in such a scenario, and if one seeks to estimate the causal effect of the treatment on a response, one needs to control for such factors. Identifying all relevant PCFs may be difficult (or impossible) given a single observational study. Instead, we argue that if one can observe a sequ...

    Full Text Available Our society is on the brink of health care system reorganization and implementation of new medical technology. Hospitals have to be a core component of the medical revolution so they have to be prepared for the upcoming leap in their development. If Poland wants to be a pioneer in providing new medical solutions, the current ineffective system has to be changed. The necessary action should be taken to deal with the financial problems Polish hospitals have faced for over 20 years. The current structure of hospitals - SPZOZ, is old-fashioned and cannot adapt to a turbulent social and economic environment. The hospitals should be commercialized and restructured. Being capitalized companies will give incentives and new tools to deal with financial problems. The article presents an example of the commercialized hospital in Łańcut. We make the observations that commercialization increases: a hospital’s profitability, its employment productivity, its capital investment spending and leverage. The case proves that the transformation of hospitals to capital companies proposed by the Ministry of Health may be an appropriate approach and it does work once a reasonable management board is in charge. However, the legal structure alteration should be treated as the first step in the overall restructuring process. The article highlights the problem of managers of Polish hospitals who do not only struggle with financial shortages, but barely know which business model they should follow after commercialization to successfully run the restructuring process. Having examined the LMC the authors are crafting a prelude to the overall research on already commercialized hospitals to find an appropriate business model.

  11. [Connectionist models of social learning: a case of learning by observing a simple task].

    Science.gov (United States)

    Paignon, A; Desrichard, O; Bollon, T

    2004-03-01

    This article proposes a connectionist model of the social learning theory developed by Bandura (1977). The theory posits that an individual in an interactive situation is capable of learning new behaviours merely by observing them in others. Such learning is acquired through an initial phase in which the individual memorizes what he has observed (observation phase), followed by a second phase where he puts the recorded observations to use as a guide for adjusting his own behaviour (reproduction phase). We shall refer to the two above-mentioned phases to demonstrate that it is conceivable to simulate learning by observation otherwise than through the recording of perceived information using symbolic representation. To this end we shall rely on the formalism of ecological neuron networks (Parisi, Cecconi, & Nolfi, 1990) to implement an agent provided with the major processes identified as essential to learning through observation. The connectionist model so designed shall implement an agent capable of recording perceptive information and producing motor behaviours. The learning situation we selected associates an agent demonstrating goal-achievement behaviour and an observer agent learning the same behaviour by observation. Throughout the acquisition phase, the demonstrator supervises the observer's learning process based on association between spatial information (input) and behavioural information (output). Representation thus constructed then serves as an adjustment guide during the production phase, involving production by the observer of a sequence of actions which he compares to the representation stored in distributed form as constructed through observation. An initial simulation validates model architecture by confirming the requirement for both phases identified in the literature (Bandura, 1977) to simulate learning through observation. The representation constructed over the observation phase evidences acquisition of observed behaviours, although this phase

    Full Text Available Introduction. Ectopic lymphoid neogenesis and the presence of IgG4-positive plasmacytes have been confirmed in chronic inflammatory sclerosing diseases. This study aims to investigate hip synovial tissues of ankylosing spondylitis (AS patients for IgG4-positive plasma cells and ectopic lymphoid tissues with germinal centers (GCs. Methods. Synovial samples were collected from 7 AS patients who received total hip replacement and were evaluated using immunohistochemistry for the presence of CD20+ B-cells, CD3+ T-cells, CD21+ follicular dendritic cells (FDC, and CD38+ plasma cells. Furthermore, immunoglobulin G (IgG and IgG4, IgA, IgM, and complement components C3d and C4d in synovia were evaluated. Both synovial CD21+ FDCs and IgG4-producing plasmacytes were analyzed. Results. All seven patients had severe fibrosis. Massive infiltrations of lymphocytes were found in 5 out of 7 patients’ synovia. Ectopic lymphoid tissues with CD21+ FDC networks and IgG4-positive plasma cells were observed coincidentally in two patients’ synovia. Conclusion. The pathophysiological mechanism of AS patients’ hip damage might be related to the coincidental presence of ectopic lymphoid tissue with FDCs network and IgG4-positive plasma cells identified here for the first time in AS patients’ inflamed synovial tissue.

    Case rate payments combined with utilization monitoring may have the potential to improve the quality of care by reducing over and under-treatment. Thus, a national managed care organization introduced case rate payments at one multi-site radiation oncology provider while maintaining only fee-for-service payments at others. This study examined whether the introduction of the payment method had an effect on radiation fractions administered when compared to clinical guidelines. The number of fractions of radiation therapy delivered to patients with bone metastases, breast, lung, prostate, and skin cancer was assessed for concordance with clinical guidelines. The proportion of guideline-based care ascertained from the payer's claims database was compared before (2011) and after (2013) the payment method introduction using relative risks (RR). After the introduction of case rates, there were no significant changes in guideline-based care in breast, lung, and skin cancer; however, patients with bone metastases and prostate cancer were significantly more likely to have received guideline-based care (RR = 2.0 and 1.1, respectively, p<0.05). For the aggregate of all cancers, the under-treatment rate significantly declined (p = 0.008) from 4% to 0% after the introduction of case rate payments, while the over-treatment rate remained steady at 9%, with no significant change (p = 0.20). These findings suggest that the introduction of case rate payments did not adversely affect the rate of guideline-based care at the provider examined. Additional research is needed to isolate the effect of the payment model and assess implications in other populations. PMID:26870963

    2015-08-01

    Recent studies of M31, the Galactic Centre (GC), and galaxy clusters have made tentative detections of an X-ray line at ˜3.5 keV that could be produced by decaying dark matter. We use high-resolution simulations of the Aquarius project to predict the likely amplitude of the X-ray decay flux observed in the GC relative to that observed in M31, and also of the GC relative to other parts of the Milky Way halo and to dwarf spheroidal galaxies. We show that the reported detections from M31 and the GC are compatible with each other, and with upper limits arising from high galactic latitude observations, and imply a decay time τ ˜ 1028 s. We argue that this interpretation can be tested with deep observations of dwarf spheroidal galaxies: in 95 per cent of our mock observations, a 1.3 Ms pointed observation of Draco with XMM-Newton will enable us to discover or rule out at the 3σ level an X-ray feature from dark matter decay at 3.5 keV, for decay times τ < 0.8 × 1028 s.

    International Nuclear Information System (INIS)

    The state, condition, and tendencies of the agro-ecosystems (AE) of the Paysandu farming center of the Universidad Nacional de Colombia, sede Medellin were characterized and evaluated by means of parameterization and analysis of the various technological receptivity (RT, after the Spanish initials) and technological intensity (IT), based upon a methodological proposal of Velez and Gasto (1999), in terms of AE diversity and of the uses, management, and technological acceptance, techno-structural and hydro-structural endowment, potential productivity and services to the local, regional, and national society. The results showed that the greater part of the center (72%) has very low RT; which does not permit the establishment of mechanized advanced agro-technological management systems (SMA) however, 69.8% of the area is managed with SMA adequate for the restrictions imposed by the RT sixty-two percent of the area of the center, principally under pasture cover for dairy cattle production, is managed with advanced SMA. As a result of the interaction between RT and the SMA employed, six AE were identified, of which three, that represent 69.8% of the area (100.2 ha.), are managed with technologies adequate for their biophysical conditions or with technological receptivity (adequate IT), and the other three, that represent 28,57% of the are (43.1 ha.) ore managed with technologies that do not correspond to their RT conditions (tradition IT) which leads to a deterioration of their biophysical and ecological conditions

    Guangzhou Open University (GZOU) has been considering the system construction as an important approach to extending the Radio and TV university (RTVU) education to the grass-root stratum and establishing bases for developing tal-ents. For years, in addition to local RTVUs, GZOU has established an array of learning centers by cooperating with more than 100 partners from a variety of industries, enterprises, secondary and higher vocational schools, social organizations, groups and other training institutions. Such learning centers have taken on different characteristics corresponding to the school’s three developmental phases, that is, period before 1999, when the Open Education Pilot Project was launched; that between 1999 and 2006, when the Conclusive Evaluation was implemented; and the one after 2006. At present, the constitution of Learning Center in GZOU System holds out some notable features as follows: diversity of collaborators and cooperative modes, and ex-tensiveness of function and orientation. These strengths would facilitate the GZOU’s endeavor to transform itself from a local RTVU into the Open University.

  7. Meridian-scanning photometer, coherent HF radar, and magnetometer observations of the cusp: a case study

    Directory of Open Access Journals (Sweden)

    S. E. Milan

    Full Text Available The dynamics of the cusp region and post-noon sector for an interval of predominantly IMF By, Bz < 0 nT are studied with the CUTLASS Finland coherent HF radar, a meridian-scanning photometer located at Ny Ålesund, Svalbard, and a meridional network of magnetometers. The scanning mode of the radar is such that one beam is sampled every 14 s, and a 30° azimuthal sweep is completed every 2 minutes, all at 15 km range resolution. Both the radar backscatter and red line (630 nm optical observations are closely co-located, especially at their equatorward boundary. The optical and radar aurora reveal three different behaviours which can interchange on the scale of minutes, and which are believed to be related to the dynamic nature of energy and momentum transfer from the solar wind to the magnetosphere through transient dayside reconnection. Two interpretations of the observations are presented, based upon the assumed location of the open/closed field line boundary (OCFLB. In the first, the OCFLB is co-located with equatorward boundary of the optical and radar aurora, placing most of the observations on open field lines. In the second, the observed aurora are interpreted as the ionospheric footprint of the region 1 current system, and the OCFLB is placed near the poleward edge of the radar backscatter and visible aurora; in this interpretation, most of the observations are placed on closed field lines, though transient brightenings of the optical aurora occur on open field lines. The observations reveal several transient features, including poleward and equatorward steps in the observed boundaries, "braiding" of the backscatter power, and 2 minute quasi-periodic enhancements of the plasma drift and optical intensity, predominantly on closed field lines.

    Full Text Available Abstract Introduction Pubic osteomyelitis should be suspected in athletic individuals with sudden groin pain, painful restriction of hip movements and fever. It is an infrequent and confusing disorder, which is often heralded by atypical gait disturbance and diffuse pain in the pelvic girdle. The most common pathogen is Staphylococcus aureus but, on occasions, efforts to identify infectious agents sometimes prove negative. Pubic osteomyelitis due to Streptococcus viridans has not been reported previously in the literature. Case presentation We describe the case of a fit 24-year-old athlete, who had a wisdom tooth extracted 2 weeks prior to the presentation, which could have served as a port of entry and predisposed the patient to transient bacteraemia. Conclusion S. viridans is well known for causing infective endocarditis of native damaged heart valves, but to the best of the authors' knowledge it has not been reported previously as a cause of pubic osteomyelitis. We believe that this case should alert physicians to the association between dental procedures and osteomyelitis of the pubis secondary to S. viridans.

  15. Observation level combination of SLR and VLBI with c5++: A case study for TIGO

    2014-01-01

    A multi-technique space geodetic analysis software named c5++ has been developed and allows one to combine data on the observation level. With SLR and VLBI modules being ready and tested, this software has been used to compute coordinate time series of the geodetic fundamental station TIGO, located near Concepción, Chile. It can be shown that the combination of space geodetic data on the observation level leads to a significant improvement of station position repeatability, which is an important measure for the stability of a station in the terrestrial reference frame. Moreover, it could be demonstrated that the geophysical signal of the post-seismic tectonic plate movement is usually more complete than detected by any of the two single-technique solutions. In addition, it has been confirmed that so-called nuisance parameters, which are relying on data from a single technique, are not biased when combing observations from different space geodetic techniques.

Atmospheric suspended particles (aerosols) have significant radiative and environmental impacts, affecting human health, visibility and climate. Therefore, they are regulated by air quality standards worldwide, and monitored by regional observation networks. Satellite observations vastly improve the horizontal and temporal coverage, providing daily distributions. Aerosols are currently estimated using aerosol optical depth (AOD) retrievals, a quantitative measure of the extinction of solar radiation by aerosol scattering and absorption between the point of observation and the top of the atmosphere. Even though remarkable progresses in aerosol modeling by chemistry-transport models (CTM) and measurement experiments have been made in recent years, there is still a significant divergence between the modeled and observed results. However, AOD retrievals from satellites remains a highly challenging task mostly because it depends on a variety of different parameters such as cloud contamination, surface reflectance contributions and a priori assumptions on aerosol types, each one of them incorporating its own difficulties. Therefore, comparisons between CTM and observations are often difficult to interpret. In this presentation, we will discuss comparisons between regional modeling (CHIMERE CTM) over Mexico and satellite observations obtained by the POLDER instrument embarked on PARASOL micro-satellite. After a comparison of the model AOD with the retrieved L2 AOD, we will present an alternative

    To investigate the pregnancy outcome of the fetuses with trisomy 18, we studied 123 cases of trisomy 18 who were born at our hospital from 1993 to 2009. Among them, 95.9% were diagnosed with trisomy 18 prenatally. Prenatal ultrasound findings showed fetal growth restriction in 77.2%, polyhydramnios in 63.4% and congenital heart defects in 95.1%. For 18 cases, cesarean section (C-section) was chosen, and for 75 cases, transvaginal delivery was chosen. Premature delivery occurred in 35.5%. Stillbirths occurred in 50 cases (40.7%). Fetal demise before onset of labor occurred in 30 cases and fetal demise during labor occurred in 20 cases which was 26.7% of vaginal deliveries. Among the 73 live-born infants, the survival rate for 24 h, 1 week, 1 month and 1 year were 63%, 43%, 33% and 3%. The median survival time was 3.5 days. There was no significant difference between the survival time of C-section and that of vaginal delivery. However, for the births involving breech presentation, the survival time of C-section was significantly longer than that of vaginal delivery. When the fetus is diagnosed with trisomy 18, the parents have to make many choices. These findings constitute critical information in prenatal counseling to the couples whose fetuses have been found to have trisomy 18, especially when they choose palliative approaches in the perinatal management.

  18. A Second Case of Outbursts in a Pulsating White Dwarf Observed by Kepler

    2015-09-01

    We present observations of a new phenomenon in pulsating white dwarf stars: large-amplitude outbursts at timescales much longer than the pulsation periods. The cool ({T}{eff} = 11,060 K), hydrogen-atmosphere pulsating white dwarf PG 1149+057 was observed nearly continuously for more than 78.8 day by the extended Kepler mission in K2 Campaign 1. The target showed 10 outburst events, recurring roughly every 8 day and lasting roughly 15 hr, with maximum flux excursions up to 45% in the Kepler bandpass. We demonstrate that the outbursts affect the pulsations and therefore must come from the white dwarf. Additionally, we argue that these events are not magnetic reconnection flares, and are most likely connected to the stellar pulsations and the relatively deep surface convection zone. PG 1149+057 is now the second cool pulsating white dwarf to show this outburst phenomenon, after the first variable white dwarf observed in the Kepler mission, KIC 4552982. Both stars have the same effective temperature, within the uncertainties, and are among the coolest known pulsating white dwarfs of typical mass. These outbursts provide fresh observational insight into the red edge of the DAV instability strip and the eventual cessation of pulsations in cool white dwarfs.

  19. Information content of a new observable: The case of the nuclear neutron skin

    International Nuclear Information System (INIS)

    We address two questions pertaining to the uniqueness and usefulness of a new observable: (i) Considering the current theoretical knowledge, what novel information does new measurement bring in? (ii) How can new data reduce uncertainties of current theoretical models? We illustrate these points by studying the radius of the neutron distribution of a heavy nucleus, a quantity related to the equation of state for neutron matter that determines properties of nuclei and neutron stars. By systematically varying the parameters of two theoretical models and studying the resulting confidence ellipsoid, we quantify the relationships between the neutron skin and various properties of finite nuclei and infinite nuclear matter. Using the covariance analysis, we identify observables and pseudo-observables that correlate, and do not correlate, with the neutron skin. By adding the information on the neutron radius to the pool of observables determining the energy functional, we show how precise experimental determination of the neutron radius in 208Pb would reduce theoretical uncertainties on the neutron matter equation of state.

    We present broad band optical afterglow observations of a long duration GRB 060124 using the 1.04-m Sampurnanand Telescope at ARIES, Nainital and the 2.01-m HCT at IAO, Hanle, including the earliest ground based observations in R band for this GRB. We determine the decay slope of the light curve at different bands and examine the reality of a proposed jet break. We use data from our observations as well as others reported in the literature to construct light curves in different bands and make power law fits to them. The spectral slope of the afterglow emission in the optical band is estimated. Our first R-band observations were taken $\\sim 0.038$~d after burst. We find that all available optical data after this epoch are well fit by a single power law, with a temporal flux decay index $\\alpha\\sim 0.94$. We do not find any evidence of a jet break within our data, which extend till $\\sim 2$~d after the burst. The X-ray light curve, however, shows a distinct break around 0.6 day. We attribute this break to a ste...

    The possible short gamma-ray burst (GRB) observed by {\\it Fermi}/GBM in coincidence with the first gravitational wave (GW) detection, offers new ways to test GRB prompt emission models. Gravitational wave observations provide previously unaccessible physical parameters for the black hole central engine such as its horizon radius and rotation parameter. Using a minimum jet launching radius from the Advanced LIGO measurement of GW~150914, we calculate photospheric and internal shock models and find that they are marginally inconsistent with the GBM data, but cannot be definitely ruled out. Dissipative photosphere models, however have no problem explaining the observations. Based on the peak energy and the observed flux, we find that the external shock model gives a natural explanation, suggesting a low interstellar density ($\\sim 10^{-3}$ cm$^{-3}$) and a high Lorentz factor ($\\sim 2000$). We only speculate on the exact nature of the system producing the gamma-rays, and study the parameter space of a generic Bl...

    Satellite-based precipitation estimates (SPEs) are promising alternative precipitation data for climatic and hydrological applications, especially for regions where ground-based observations are limited. However, existing satellite-based rainfall estimations are subject to systematic biases. This study aims to adjust the biases in the Precipitation Estimation from Remotely Sensed Information using Artificial Neural Networks-Cloud Classification System (PERSIANN-CCS) rainfall data over Chile, using gauge observations as reference. A novel bias adjustment framework, termed QM-GW, is proposed based on the nonparametric quantile mapping approach and a Gaussian weighting interpolation scheme. The PERSIANN-CCS precipitation estimates (daily, 0.04°×0.04°) over Chile are adjusted for the period of 2009-2014. The historical data (satellite and gauge) for 2009-2013 are used to calibrate the methodology; nonparametric cumulative distribution functions of satellite and gauge observations are estimated at every 1°×1° box region. One year (2014) of gauge data was used for validation. The results show that the biases of the PERSIANN-CCS precipitation data are effectively reduced. The spatial patterns of adjusted satellite rainfall show high consistency to the gauge observations, with reduced root-mean-square errors and mean biases. The systematic biases of the PERSIANN-CCS precipitation time series, at both monthly and daily scales, are removed. The extended validation also verifies that the proposed approach can be applied to adjust SPEs into the future, without further need for ground-based measurements. This study serves as a valuable reference for the bias adjustment of existing SPEs using gauge observations worldwide.

    The authors report a new case of leiomyosarcoma of the duodenum. The exo-luminal growth and the volume of this tumor explain the difficulties of the imaging methods diagnostic. Computed tomography, magnetic resonance imaging and angiography were not sufficient to determine the origin of the tumor. Surgical exposure itself was not conclusive and only pathology provided the definitive diagnosis. We think that endoscopic ultrasonography should be indicated in these submucosal tumors of the duodenum to differentiates them from pancreatic neoplasms. (authors). 9 refs., 3 figs.

    Full Text Available BACKGROUND: Clinical practice guidelines have been slowly and inconsistently applied in clinical practice, and certain evidence-based, guideline-driven therapies for heart failure (HF have been significantly underused. The purpose of this study was to survey guideline compliance and its effect on clinical outcomes in the treatment of systolic HF in Korea. METHOD AND RESULTS: The SUrvey of Guideline Adherence for Treatment of Systolic Heart Failure in Real World (SUGAR trial was a multi-center, retrospective, observational study on subjects with systolic HF (ejection fraction <45% admitted to 23 university hospitals. The guideline adherence indicator (GAI was defined as a performance measure on the basis of 3 pharmacological classes: angiotensin-converting enzyme inhibitor (ACEI or angiotensin receptor II blocker (ARB, beta-blocker (BB, and aldosterone antagonist (AA. Based on the overall adherence percentage, subjects were divided into 2 groups: those with good guideline adherence (GAI ≥50% and poor guideline adherence (GAI <50%. We included 1319 regional participants as representatives of the standard population from the Korean national census in 2008. Adherence to drugs at discharge was as follows: ACEI or ARB, 89.7%; BB, 69.2%; and AA, 65.9%. Overall, 82.7% of the patients had good guideline adherence. Overall mortality and re-hospitalization rates at 1 year were 6.2% and 37.4%, respectively. Survival analysis by log-rank test showed a significant difference in event-free survival rate of mortality (94.7% vs. 89.8%, p = 0.003 and re-hospitalization (62.3% vs. 56.4%, p = 0.041 between the good and poor guideline-adherence groups. CONCLUSIONS: Among patients with systolic HF in Korea, adherence to pharmacologic treatment guidelines as determined by performance measures, including prescription of ACEI/ARB and BB at discharge, was associated with improved clinical outcomes.

    The study of neighborhood characteristics and their effects on individuals has become an area of increasing attention by scholars from various disciplines in developed countries. Although there are various methods to study neighborhoods and their impact on human populations, one of the most used is the Systematic Social Observation -Observación Sistemática de Vecindarios (OSV), in Spanish-because it allows the collection of information about various features of the physical, social, environmental and economic characteristics of neighborhoods. The purpose of this article is to (i) briefly present some research on neighborhood effects influential in the U.S., ii) describe how they Systematic Social Observation was designed and implemented in the city of Santiago, Chile, iii) discuss some facilitators and obstacles of the implementation process and, finally iv) list possible contributions and limitations this approach would offer the profession of social work in Chile.

    2011-01-01

    International audience This paper considers the problem of state estimation in autonomous navigation from a theoretical perspective. In particular, the investigation regards problems where the information provided by the sensor data is not sufficient to carry out the state estimation (i.e. the state is not observable). For these systems, the concept of continuous symmetry is introduced. Detecting the continuous symmetries of a given system has a very practical importance. It allows us to d...

    Full Text Available A focus of the Arctic Research of the Composition of the Troposphere from Aircraft and Satellites (ARCTAS mission was examination of bromine photochemistry in the spring time, high latitude troposphere based on aircraft and satellite measurements of BrO and related species. The NASA DC-8 aircraft utilized a chemical ionization mass spectrometry (CIMS instrument to measure BrO and a mist chamber (MC to measure soluble bromide. We have determined that the MC detection efficiency to molecular bromine (Br2, hypobromous acid (HOBr, bromine oxide (BrO, and hydrogen bromide (HBr as soluble bromide (Br was 0.9±0.1, 1.06±0.30, 0.4±0.1, and 0.95±0.1, respectively. These efficiency factors were used to estimate soluble bromide levels along the DC-8 flight track of 17 April 2008 from photochemical calculations constrained to in situ BrO measured by CIMS. During this flight, the highest levels of soluble bromide and BrO were observed and atmospheric conditions were ideal for the space-borne observation of BrO. The good agreement (R2 = 0.76; slope = 0.98; intercept = −3.5 pptv between modeled and observed soluble bromide, when BrO was above detection limit (>2 pptv under unpolluted conditions (NO < 100 pptv, indicates that the CIMS BrO measurements were consistent with the MC soluble bromide. Tropospheric BrO vertical column densities (BROTROPVCD derived from CIMS BrO observations compare well with BROTROPVCD from OMI on 17 April 2008.

  1. The role of the observational approach in RI planning: WAG 5 case study

    International Nuclear Information System (INIS)

    A Remedial Investigation (RI) Plan was developed for the Oak Ridge National Laboratory (ORNL) Waste Area Grouping (WAG) 5 in March 1988 and submitted to the Environmental Protection Agency (EPA) Region IV and the State of Tennessee for review and approval. The observational approach was evaluated by the ORNL Environmental Restoration (ER) Program and accepted by EPA as an accelerated and cost-effective approach to the RI/Feasibility Study (FS) process for remediation of WAG 5. The traditional approach used in preparing the 1988 RI Plan focused on data completeness, included a typical range of RI data-gathering activities for determining the nature and extent of contamination at WAG 5, and used multiple iterations of sampling activities to deal with uncertainties without consideration of potential deviations. In fall 1991, a revised Field Sampling Plan (FSP) was developed that used the observational approach to integrate site characterization with site remediation needs. This approach recognized the uncertainties of site characterization/remedial planning and developed contingency plans for dealing with them. The observational approach emphasizes data sufficiency to support remedial planning decisions for WAG 5

    Full Text Available When processing satellite altimetry data for Mean Sea Surface (MSS modelling in coastal environments many problems arise. The degradation of the accuracy of the Sea Surface Height (SSH observations close to the coastline and the usually irregular pattern and variability of the sea surface topography are the two dominant factors which have to be addressed. In the present paper, we study the statistical behavior of the SSH observations in relation to the range from the coastline for many satellite altimetry missions and we make an effort to minimize the effects of the ocean variability. Based on the above concepts we present a process strategy for the homogenization of multi satellite altimetry data that takes advantage ofweighted SSH observations and applies high degree polynomials for the adjustment and their uniffcation at a common epoch. At each step we present the contribution of each concept to MSS modelling and then we develop a MSS, a marine geoid model and a grid of gravity Free Air Anomalies (FAA for the area under study. Finally, we evaluate the accuracy of the resulting models by comparisons to state of the art global models and other available data such as GPS/leveling points, marine GPS SSH’s and marine gravity FAA’s, in order to investigate any progress achieved by the presented strategy

    We present study of a typical explosive event (EE) at sub-arcsecond scale witnessed by strong non-Gaussian profiles with blue- and red-shifted emission of up to 150 km/s seen in the transition-region Si IV 1402.8 \\AA, and the chromospheric Mg II k 2796.4 \\AA\\ and C II 1334.5 \\AA\\ observed by the Interface Region Imaging Spectrograph at unprecedented spatial and spectral resolution. For the first time a EE is found to be associated with very small-scale ($\\sim$120 km wide) plasma ejection followed by retraction in the chromosphere. These small-scale jets originate from a compact bright-point-like structure of $\\sim$1.5" size as seen in the IRIS 1330 \\AA\\ images. SDO/AIA and SDO/HMI co-observations show that the EE lies in the footpoint of a complex loop-like brightening system. The EE is detected in the higher temperature channels of AIA 171 \\AA, 193 \\AA\\ and 131 \\AA\\ suggesting that it reaches a higher temperature of log T$=5.36\\pm0.06$ (K).

    We present observations of a new phenomenon in pulsating white dwarf stars: large-amplitude outbursts at timescales much longer than the pulsation periods. The cool (Teff = 11,010 K), hydrogen-atmosphere pulsating white dwarf PG 1149+057 was observed nearly continuously for more than 78.8 d by the extended Kepler mission in K2 Campaign 1. The target showed 10 outburst events, recurring roughly every 8 d and lasting roughly 15 hr, with maximum flux excursions up to 45% in the Kepler bandpass. We demonstrate that the outbursts affect the pulsations and therefore must come from the white dwarf. Additionally, we argue that these events are not magnetic reconnection flares, and are most likely connected to the stellar pulsations and the relatively deep surface convection zone. PG 1149+057 is now the second cool pulsating white dwarf to show this outburst phenomenon, after the first variable white dwarf observed in the Kepler mission, KIC 4552982. Both stars have the same effective temperature, within the uncertain...

    2013-01-01

    Full Text Available Objectives: To describe Magnetic Resonance Urography (MRU appearances of the circumcaval ureter, a rare congenital cause of hydronephrosis. Materials and Methods: Seven cases of circumcaval ureter, suspected on intravenous urography (IVU, underwent subsequent static MRU using heavily T2-weighted sequences. Results: The various appearances of circumcaval ureter on IVU and MRU were studied and compared. The circumcaval portion of the ureter was especially well seen on axial MRU sections, though this portion was routinely not visualized on IVU. In one case with a ureteric calculus, MRU also depicted a circumcaval course of the ureter, thus providing a complete diagnosis. In yet another case, where a circumcaval ureter was suspected on IVU, MRU proved the actual cause of ureteric obstruction to be a crossing vessel. Conclusion: Static MRU using heavily T2-weighted coronal and axial sequences can make or exclude the diagnosis of circumcaval ureter unequivocally.

    Full Text Available The province of Tekirdağ, due to its geographical setting, is situated in a place of transition connecting our country to Europe. The coastal zone of Tekirdağ, which attracts attention with its natural, cultural and historical riches, has a very intensive use. Today, as a result of rapid urbanization, industrialization and increasing population densities, open and green areas functioning as the lungs of cities are decreasing every day and consequently biological order is changing, the balance between structured areas and natural surrounding is deteriorating and the various use of coastline is changing. The coastline plays an important role in satisfying the need of the population of the administrative center of Tekirdağ for open areas and in providing the users with their recreational needs within their daily life. In this study, the aim has been to examine the present situation of the coastline of the center district of Tekirdağ, which has an important function in terms of urban open and green areas, to present the recreational potential use of the area by the way of an application method and to provide sustainability of natural and cultural sources and the precautions to be taken. Through research, Tekirdağ coastline were found to be 65% of the recreation potential. Accordingly, the recreation potential of this area the "high" was considered to be.

    Intoxications with drugs, household products and plants include approximately 70% of all cases reported to the STIZ. Among drugs the most frequent severe intoxications occur with benzodiazepines and antidepressives; therefore, the toxicological risk of these substances are investigated in more detail. In children, accidental intoxications with household products are most frequent. In these cases special emphasis must be put on preventive measures. Plants only rarely lead to severe intoxications; however, if toxic symptoms do occur, the analysis of their causality and overall risk for the patient can be a difficult task and frequently requires the involvement of a plant specialist.

    Procalcitonin (PCT) levels are commonly used for diagnostic guidance in routine bacterial infections. By contrast, little data are currently available regarding PCT in parasitic diseases, and its role in cases of invasive amoebiasis has not yet been described. For this purpose, 35 adult patients with a proven diagnosis of invasive or digestive amoebiasis were included in a 4-year study period. Serum PCT was retrospectively assessed. Results were analysed with regard to the usual inflammatory biomarkers, like C-reactive protein (CRP). PCT was significantly higher in patients with proven invasive amoebiasis than in digestive amoebiasis (mean value: 4.03 μg/L versus 0.07 μg/L, respectively; P < 0.001), but the SD was greater than with CRP, and the effect was less than that demonstrated in bacterial infections. By contrast, PCT was not shown to be elevated during digestive amoebiasis. PMID:26388549

    Full Text Available Background: Growth hormone deficiency (GHD in adults is associated with a cluster of cardiovascular risk factors that may contribute to an increased mortality for cardiovascular disease. In children, relatively few studies have investigated the effect of GHD and replacement therapy on cardiac performance and metabolic abnormalities that may place them at a higher risk of cardiovascular disease (CVD at an early age. Aim: This study was aimed to assess the left ventricular function, lipid profile, and degree of insulin resistance in Egyptian children with GHD before and after 1 year of GH replacement therapy. Settings and Design: Prospective case-control study, single-center study. Materials and Methods: Thirty children with short stature due to GHD were studied in comparison to 20 healthy age- and sex-matched children. All subjects were subjected to history, clinical examination, auxological assessment, and echocardiography to assess the left ventricular function. Blood samples were collected for measuring IGF-1, lipid profile (Total, LDL, HDL cholesterol, triglyceride, and atherogenic index (AI, fasting blood sugar, and fasting insulin levels. In addition, basal and stimulated GH levels were measured in children with suspected GHD. Statistical Analysis Used: Student′s t-test was used for parametric data, and the Mann-Whitney U-test was used for non-parametric data. Results: Total, LDL cholesterol, triglyceride, AI, and insulin were significantly higher in children with GHD than in healthy controls at baseline. After 12 months of GH replacement therapy, total, LDL cholesterol, triglyceride, AI and insulin were significantly decreased, while homeostatic model assessment for insulin resistance index (HOMA-IR was significantly increased compared to both pre-treatment and control values. At baseline, the left ventricular mass (LVM and left ventricular mass index (LVMi were significantly lower in GHD children than in controls. After 12 months of GH

    Full Text Available Abstract Background We address the goal of curating observations from published experiments in a generalizable form; reasoning over these observations to generate interpretations and then querying this interpreted knowledge to supply the supporting evidence. We present web-application software as part of the 'BioScholar' project (R01-GM083871 that fully instantiates this process for a well-defined domain: using tract-tracing experiments to study the neural connectivity of the rat brain. Results The main contribution of this work is to provide the first instantiation of a knowledge representation for experimental observations called 'Knowledge Engineering from Experimental Design' (KEfED based on experimental variables and their interdependencies. The software has three parts: (a the KEfED model editor - a design editor for creating KEfED models by drawing a flow diagram of an experimental protocol; (b the KEfED data interface - a spreadsheet-like tool that permits users to enter experimental data pertaining to a specific model; (c a 'neural connection matrix' interface that presents neural connectivity as a table of ordinal connection strengths representing the interpretations of tract-tracing data. This tool also allows the user to view experimental evidence pertaining to a specific connection. BioScholar is built in Flex 3.5. It uses Persevere (a noSQL database as a flexible data store and PowerLoom® (a mature First Order Logic reasoning system to execute queries using spatial reasoning over the BAMS neuroanatomical ontology. Conclusions We first introduce the KEfED approach as a general approach and describe its possible role as a way of introducing structured reasoning into models of argumentation within new models of scientific publication. We then describe the design and implementation of our example application: the BioScholar software. This is presented as a possible biocuration interface and supplementary reasoning toolkit for a larger

    We report on the implantation of boron in individual, electrically contacted germanium nanowires with varying diameter and present a technique that monitors the electrical properties of a single device during implantation of ions. This method gives improved access to study the dynamic annealing ability of the nanowire at room temperature promoted by its quasi-one-dimensional confinement. Based on electrical data, we find that the dopant activation efficiency is nontrivially diameter dependent. As the diameter decreases, a transition from a pronounced dynamic-annealing to a radiation-damage dominated regime is observed.

    Atmospheric aerosol over Macao was monitored by using a 355 nm Mie scattering lidar during the dust event on March 22nd, 2010. Vertical profiles of aerosol extinction coefficients were obtained and correlated with local PM10 concentration. The near-surface aerosol extinction coefficients have good agreement with PM10 concentration values. The aerosol extinction vertical profiles showed that there were distinct layers of dust aerosol concentration. The source and tracks of dust aerosol were analyzed by back-trajectory simulation. Observations showed that this lidar could run well even in dust storm episode, and it would help to further the study on aerosol properties over Macao. PMID:22582620

  19. Topical session proceedings of the 5. IGSC meeting on: observations regarding the safety case in recent safety assessment studies

    International Nuclear Information System (INIS)

    Within the NEA, the IGSC (Integration Group for the Safety Case) has, as an essential role, to develop common views on such key aspects of the safety case. Therefore, since the inauguration of the IGSC in 2000, four meetings were organised with topical sessions to explore various of these key aspects. This is a report on the fifth such topical session, held as part of the 5. plenary meeting of the IGSC. The session was attended by 36 participants, representing waste management organisations and regulatory authorities from 16 NEA member countries, the IAEA and the European Commission. The purpose of this topical session was to provide support to the finalising of the IGSC safety case brochure by getting a description of the safety case content of the IAEA Draft Safety Requirements document and by getting an overview of progress that could be observed from national organisations on developing their cases for system safety and/or developing the required methodologies. The objective was that the IGSC safety case brochure should be supportive of the IAEA/NEA document, and be reflective of the experience of the IGSC member programmes and organisations. The topical session was mainly aimed at exchanging information on: - The safety case related content of the proposed IAEA/NEA document (currently titled: 'IAEA Safety Standards Series, Geological Disposal of Radioactive Waste, Draft Safety Requirements (DS-154)'). - National programmes where safety assessments have recently been completed, e.g. ONDRAF/NIRAS, Nagra and Andra. - Feedback from international peer reviews, e.g. the Andra Dossier 2001 Argile, the Belgian SAFIR 2 report, the SR 97 report and the US-DOE Yucca Mountain TSPA. - The evolution of some national assessment methods and approaches e.g. SKB and Nagra. - The content of the draft IGSC safety case brochure entitled: 'The Nature and Purpose of the Post-closure Safety Case in Geological Disposal'.

    The objective of this work is to apply a new microphysical parameterization for fog visibility for potential use in numerical weather forecast simulations, and to compare the results with ground-based observations. The observations from the Fog Remote Sensing And Modeling (FRAM) field which took place during the winter of 2005 2006 over southern Ontario, Canada (Phase I) were used in the analysis. The liquid water content (LWC), droplet number concentration (N d ), and temperature (T) were obtained from the fog measuring device (FMD) spectra and Rosemount probe, correspondingly. The visibility (Vis) from a visibility meter, liquid water path from microwave radiometers (MWR), and inferred fog properties such as mean volume diameter, LWC, and N d were also used in the analysis. The results showed that Vis is nonlinearly related to both LWC and N d . Comparisons between newly derived parameterizations and the ones already in use as a function of LWC suggested that if models can predict the total N d and LWC at each time step using a detailed microphysics parameterization, Vis can then be calculated for warm fog conditions. Using outputs from the Canadian Mesoscale Compressible Community (MC2) model, being tested with a new multi-moment bulk microphysical scheme, the new Vis parameterization resulted in more accurate Vis values where the correction reached up to 20 50%.

    We present the results of a search for dwarf novae (DNe) in globular clusters (GCs). It is based on the largest available homogeneous sample of observations, in terms of the time span, number of observations and number of clusters. It includes 16 Galactic GCs and yielded two new certain DNe: M55-CV1 and M22-CV2. All previously known systems located in our fields were recovered, too. We surveyed M4, M5, M10, M12, M22, M30, M55, NGC 288, NGC 362, NGC 2808, NGC 3201, NGC 4372, NGC 6362, NGC 6752, omega Cen (NGC 5139) and 47 Tuc (NGC 104). The discovery of two DNe, namely M55-CV1 and M22-CV2, was already reported by Kaluzny et al. (2005) and Pietrukowicz et al. (2005), respectively. In the remaining 14 GCs we found no certain new DNe. Our result raises the total number of known DNe in the Galactic globular clusters to 12 DNe, distributed among 7 clusters. Our survey recovered all three already known erupting cataclysmic variables (CVs) located in our fields, namely M5-V101, M22-CV1, and V4 in the foreground of M3...

  3. What is driving CO2 emissions in a typical manufacturing center of South China? The case of Jiangsu Province

    International Nuclear Information System (INIS)

    Investigating CO2 emissions of China's manufacturing centers contributes to local and global CO2 mitigation targets. This study considers Jiangsu Province as a representation of manufacturing centers in South China. Effects of material efficiency improvements, technology development, consumption structure changes and consumption volume growth in Jiangsu Province on its CO2 emissions during 1997-2007 are investigated using structural decomposition analysis based on environmental input-output table. In order to reduce CO2 emissions, Jiangsu Province should not only rely on material efficiency improvements and technology development, but also rely on consumption structure changes. For consumption structure changes in detail, Jiangsu Province should not only focus on fixed capital formation and urban residential consumption, but also focus on international and intranational imports and exports. For the implementation of material efficiency improvements and technology development, Jiangsu Province should focus on technology innovation and international technology transfer. For the implementation of consumption structure changes, Jiangsu Province should mainly focus on identified sectors for each separate final demand category: five sectors for urban residential consumption, three sectors for fixed capital formation, four sectors for international exports, five sectors for intranational exports, three sectors for international imports and four sectors for intranational imports. - Highlights: → Effects of four factors on Jiangsu Province's CO2 emission changes are analyzed. → Key factors are identified for Jiangsu Province to achieve CO2 mitigation targets. → Key areas for consumption structure changes are analyzed. → Technology innovation and technology transfer should be concerned. → Identified sectors for each final demand category should be concerned.

  4. Talar body fatigue stress fractures: three cases observed in elite female gymnasts

    International Nuclear Information System (INIS)

    To introduce and emphasize the clinical and radiological findings of three talar body fatigue stress fractures in competitive athletes. Clinical and radiographic skeletal records of 24,562 athletes taken between 1962 and 2002 were retrospectively reviewed. Among these, 6851 files related to acute foot and ankle injuries or chronic post-traumatic sequelae were found. There were 925 (3.76%) stress fatigue fractures selected from the whole collection. Among these there were three cases (0.32%) of talar body stress fractures diagnosed in elite female gymnasts 15 - 17 years old. The negative first radiograph become positive 4-6 weeks later. Scintigraphy was positive at an early stage and consistent for the diagnosis. CT and MRI gave positive results 1-2 weeks after the beginning of symptoms which were always greatly diagnostic. The sports medicine literature lacks reports of talar body fatigue stress fractures. The poor initial sensitivity of radiography makes it problematic to establish an early diagnosis. A wise combination of scintigraphy, CT and MRI has therefore to be relied upon. Familiarity with this rare location for a stress fracture may prevent delayed diagnosis and long-lasting damage, both of which are important factors in competitive athletes. (orig.)

    Full Text Available Traditionally, Live High-Train High (LHTH interventions were adopted when athletes trained and lived at altitude to try maximising the benefits offered by hypoxic exposure and improving sea level performance. Nevertheless, scientific research has proposed that the possible benefits of hypoxia would be offset by the inability to maintain high training intensity at altitude. However, elite athletes have been rarely recruited as an experimental sample, and training intensity has almost never been monitored during altitude research. This case study is an attempt to provide a practical example of successful LHTH interventions in two Olympic gold medal athletes. Training diaries were collected and total training volumes, volumes at different intensities, and sea level performance recorded before, during and after a 3-week LHTH camp. Both athletes successfully completed the LHTH camp (2090 m maintaining similar absolute training intensity and training volume at high-intensity (> 91% of race pace compared to sea level. After the LHTH intervention both athletes obtained enhancements in performance and they won an Olympic gold medal. In our opinion, LHTH interventions can be used as a simple, yet effective, method to maintain absolute, and improve relative training intensity in elite endurance athletes.

    Objective. Unusual manifestations are occasionally encountered in Langerhans cell histiocytosis and may be a source of confusion. The objective of this study was to determine the frequency of occurrence of the unusual manifestations in our case material. Design and patients. Thirty-four children, average age 4.4 years (range 3 months to 16 years) with 262 skeletal lesions of biopsy-proven Langerhans cell histiocytosis (LCH) were retrospectively reviewed to determine the frequency of occurrence of unusual manifestations defined either as an atypical location of a skeletal lesion or an atypical radiographic appearance of the lesion. Results. Twenty-four unusual lesions were found in this retrospective review. Among these were epiphyseal lesions, transphyseal lesions, extracranial `button` sequestra, posterior vertebral arch lesions, dural extension of vertebral lesions, and fluid-fluid levels. The finding of fluid-fluid levels has not previously been described in the radiologic literature. Involvement of unusual sites included clavicles and small bones of the hands and feet. Conclusions. Radiographic, computed tomographic, and magnetic resonance imaging of LCH yield a variety of unusual manifestations. Recognition of these varied appearances of LCH may prevent confusion of such appearances with other pathologic processes. When the unusual manifestation occurs as the initial finding of the disease, LCH should be included in the differential diagnosis. (orig.) With 7 figs., 10 refs.

    1 Hz GPS data recorded by the GNSS network of the Consejeria de Agricultura y Agua of the Murcia Region during the Mw 5.1 Lorca earthquake on May 11th 2011 is used as a test case. A Precise Point Positioning (PPP) approach is applied to analyse the earthquake-induced motion of the station LORC, located close to the epicenter. The results are validated using a conventional Double Differences (DD) processing. After applying sidereal and regional filters, the detected transient motion is about 20 millimeters in each component and clearly above noise level. The results from the two different processings are compared in view of the accuracy and applicability. The PPP approach described here can potentially be used for real-time analysis e.g. based on NTRIP streaming data. It may be used to set up an early warning system, as well as to gain real-time knowledge of ongoing earthquakes, extending the already-existing seismic information obtained from classical measurements.

    AIM: The aims of this study were to make an inventory of the disease in Ireland, to acquire better knowledge of the relationship between genetic makeup and phenotypic ocular presentation and, finally, through literature review and personal experience, to establish clear guidelines on best practice in the management of children with this rare condition both in terms of screening and follow-up. METHODS: All patients who attended the dermatology and genetic clinic in Our Lady\\'s Hospital for Sick Children, Crumlin, with incontinentia pigmenti (IP) were contacted and invited to attend the eye clinic for ocular assessment. Children who were already attending the ophthalmic services before commencement of the study had their charts reviewed for assessment. RESULTS: 11 of 19 patients agreed to attend the clinic for ocular assessment. Of these patients, nine had genetic testing. The mean age of the patients at the examination was 8 years (3 months to 29 years). In 10 patients, IP was the result of a spontaneous mutation, whereas the condition was inherited from an affected mother in one patient. Of the 11 patients with IP, 5 have visually significant ocular findings (47%). We describe the case history of four of these children briefly to outline the severity of this condition. CONCLUSION: Our patients had a significant percentage of ocular abnormalities (47%). We have outlined an examination schedule for patients with and without retinal pathology and recommend fluorescein angiography in patients with retinal pathology to fully determine the extent of ischaemia. Like other studies, early treatment with peripheral retinal photocoagulation to reduce the risk of retinal detachment is recommended in this study.

    During the summers of 2011-2012, a C-band polarimetric Shared Mobile Atmospheric Research and Teaching (SMART) radar from the University of Oklahoma was deployed to Keystone Heights, FL to study the relationship between cloud structure and the propagation of triggered and natural lightning channels. The radar was operated in Range-Height-Indicator (RHI) volume scanning mode over a narrow azimuthal sector that provided high spatial vertical resolution every 90 seconds over the rocket launch facility at the International Center for Lightning Research and Testing (ICLRT) at Camp Blanding, FL. In this presentation, we will focus on observations collected in 2011. Seven successful triggers (with return strokes) out of 20 attempts were sampled by the SMART-R from June to August. Most of the trigger attempts occurred during the dissipating stages of convection with steady ground electric field values. Specific differential phase (KDP) showed evidence of ice crystal alignment due to strong electric fields within the upper portions of the convection over ICLRT around the time of launch attempts. Consecutive RHI sweeps over ICLRT revealed changes in KDP that suggested the building of electric fields and subsequent relaxation after a triggered flash. KDP signatures relative to other radar variables will also be investigated to determine the microphysical and convective nature of the storms in which natural and triggered lightning strikes occurred. Lightning Mapping Array (LMA) sources of the triggered flash channels showed a preference for horizontal propagation just above the radar bright band associated with the melting layer. This finding agrees with several past studies that used balloon soundings and found intense layers of charge near the 0°C isotherm. The propagation path also seemed to be related to the vertical distribution of KDP in some of the triggered flashes. A preferred path through areas of generally positive values of KDP suggests that triggered lightning

The correlation between the rainfall and the prevalence of dengue was assessed byregression analysis.Results: The least square equation plot prevalence (y versus rainfall (x is y = 3.0x + 4.6 (r = 0.78,p < 0.05 (r = 0.68, p < 0.05.Interpretation & conclusion: The study indicated that the prevalence of dengue infection in Thailandmay depend on rainfall. Therefore, the surveillance and control of mosquito should be intensifiedduring the period with high rainfall is recommended. However, the other confounding factors likeambient temperature and humidity which also determine the transmission of dengue should belooked into, before concluding that the increased prevalence is a result of rainfall alone. Further,similar studies to assess the correlation between the rainfall and prevalence of infection in the othercountries are required to confirm these observations.

    2016-01-01

    Normal-pressure hydrocephalus is an almost curable disease, but the results of management are still not encouraging owing to the deceptive nature of the disease and its sensitivity to treatment. This has made the management of the disease controversial. The following self-documented report clarifies this. I have reported my experience in a scientific manner so that my colleagues can understand thoroughly certain facts related to intracranial hypertension. Achieving the optimal adjustment of the valve is a real challenge. I describe in detail the adjustment criteria I discovered. I believe that the use of biofeedback waves are almost the best way to make a proper adjustment of the valve, that is, if waves come from this machine and show increased tension of the facial muscles (high spiky waves) the valve adjustment has to be reduced without risking overdrainage. I have been observing my symptoms in some detail, which led me to a better understanding of the clinical pictures related to cerebrospinal fluid changes. I hope that uncovering my story can help with further research and improve management in this important and interesting field. PMID:27165936

    Context. Measuring star formation at a local scale is important to constrain star formation laws. Yet, it is not clear whether and how the measure of star formation is affected by the spatial scale at which a galaxy is observed. Aims. We want to understand the impact of the resolution on the determination of the spatially resolved star formation rate (SFR) and other directly associated physical parameters such as the attenuation. Methods. We have carried out a multi-scale, pixel-by-pixel study of the nearby galaxy M33. Assembling FUV, Halpha, 8, 24, 70, and 100 micron maps, we have systematically compared the emission in individual bands with various SFR estimators from a resolution of 33 pc to 2084 pc. Results. We have found that there are strong, scale-dependent, discrepancies up to a factor 3 between monochromatic SFR estimators and Halpha+24 micron. The scaling factors between individual IR bands and the SFR show a strong dependence on the spatial scale and on the intensity of star formation. Finally, str...

    The CARIBIC project (Civil Aircraft for the Regular Investigation of the Atmosphere Based on an Instrument Container) involves the monthly deployment of an instrument container equipped to make atmospheric measurements from onboard a long-range commercial airliner. Since December 2004, flights for the second phase of CARIBIC have been aboard a Lufthansa Airbus A340-600 traveling between Frankfurt, Germany and destinations in Asia, North America and South America. The instrument package housed in the container is fully automated and during each flight carries out a variety of real-time trace gas and aerosol measurements, and also collects 28 air samples, which are analyzed upon return to the laboratory. Routine measurements made from the sampling flasks include greenhouse gases, nonmethane hydrocarbons (NMHCs), and halocarbons; results of air sample analysis form the basis for the data discussed here. While the majority of CARIBIC samples represent background free tropospheric air and air representative of the upper troposphere/lower stratosphere, the aircraft also, less frequently, encounters air parcels influenced by more recent emissions. Here we present a case study of a round-trip flight between Frankfurt and Toronto, Canada during September 2007. During this flight, different air masses of unique origin were encountered; a number of samples were influenced by transport from the Gulf of Mexico, while others had source regions in Central and Southeast Asia. Samples from the Gulf of Mexico exhibited enhancements in C3-C6 alkanes, as well as a number of halogenated compounds with oceanic sources, such as methyl iodide and bromoform, while Asian samples had enhanced levels of combustion products (CO, acetylene, benzene) and anthropogenic halocarbons (methlyene chloride, chloroform, perchloroethylene). Additionally, a number of samples also showed stratospheric influence, and these samples were characterized by relatively depleted levels of many of the compounds

    Full Text Available istSOS (Istituto scienze della Terra Sensor Observation Service is an implementation of the Sensor Observation Service standard from Open Geospatial Consortium (OGC. The development of istSOS started in 2009 in order to provide a simple implementation of the Sensor Observation Service (SOS standard for the management, provision and integration of hydro-meteorological data collected in Canton Ticino (Southern Switzerland. istSOS is entirely written in Python and is based on reliable open source software like PostgreSQL/PostGIS and Apache/mod_wsgi. The authors during this presentation want to illustrate the latest software enhancements together with a real case in a production environment. Latest software enhancement includes the development of a RESTful service and of a Web-based graphical user interface that allows hydrologists a better interaction with measurements. This includes the ability of new services creation, addition of new sensors and relative metadata, visualization and manipulation of stored observations, registration of new measures and setting of system properties like observable properties and data quality codes. The study will show a real case application of the system for the provision of data to interregional partners and to a hydrological model for lake level forecasting and flooding hazard assessment. The hydrological model uses a combination of WPS (Web Processing Service and SOS for the generation of model input data. This system is linked with a dedicated geo-portal used by the civil protection for the management, alert and protection of population and assets of the Locarno area (Verbano Lake flooding. Practical considerations and technical issues will be presented and discussed.

    One-step apexification using mineral trioxide aggregate (MTA) has been reported as an alternative treatment modality with more benefits than the use of long-term calcium hydroxide for teeth with open apex. However, orthograde placement of MTA is a challenging procedure in terms of length control. This case series describes the sequence of events following apical extrusion of MTA into the periapical area during a one-step apexification procedure for maxillary central incisor with an infected immature apex. Detailed long-term observation revealed complete resolution of the periapical radiolucent lesion around the extruded MTA. These cases revealed that direct contact with MTA had no negative effects on healing of the periapical tissues. However, intentional MTA overfilling into the periapical lesion is not to be recommended.

    This paper provides an overview of Systems Engineering as it is applied in a conceptual design space systems department at the National Aeronautics and Space Administration (NASA) Marshall Spaceflight Center (MSFC) Advanced Concepts Office (ACO). Engineering work performed in the NASA MFSC's ACO is targeted toward the Exploratory Research and Concepts Development life cycle stages, as defined in the International Council on Systems Engineering (INCOSE) System Engineering Handbook. This paper addresses three ACO Systems Engineering tools that correspond to three INCOSE Technical Processes: Stakeholder Requirements Definition, Requirements Analysis, and Integration, as well as one Project Process Risk Management. These processes are used to facilitate, streamline, and manage systems engineering processes tailored for the earliest two life cycle stages, which is the environment in which ACO engineers work. The role of systems engineers and systems engineering as performed in ACO is explored in this paper. The need for tailoring Systems Engineering processes, tools, and products in the ever-changing engineering services ACO provides to its customers is addressed.

  7. Anisotropic superconductivity observed by magneto-optical imaging: A case study of yttrium barium copper oxide

    Wang, Chong

    This work studies direct Magneto-Optical Imaging (MOI) as a means to directly observe anisotropic superconductivity using (110)-oriented YBa 2Cu3O7-delta (YBCO) thin film. The MOI technique can translate magnetic field distribution directly into an optical image. It has been used to study supercurrent distribution in a superconducting thin film. A fast Fourier transform method was developed to convert the MO image into maps of current density distribution independent of the underlying models that are used to extract the critical current densities. By using this method, the inhomogeneous critical current distribution can be deduced, and current stream maps can be constructed. High quality single phase YBCO (110) thin films were fabricated by magnetron sputtering. Characterizations by X-ray diffraction, Rutherford backscattering and channeling, a scanning electron microscope, an atomic force microscope, and electric transport measurement indicates that the (110) films are single-phased, strain-free, highly oxygenated, and have a relatively smooth surface compared to the c-axis oriented counterpart prepared by the same technique. Direct imaging of the anisotropic magnetic field distribution at the surface of YBCO (110) thin film has been realized, where the unique stripe-like pattern is interpreted as based on the anisotropic critical current density model developed in this work. Geometric effects on anisotropic critical current flow have been examined. The characteristic behaviors of parabola-shaped discontinuity-lines (d-line) in an anisotropic thin film sample are discussed. Calculations of the critical currents at step-edged defects on anisotropic thin-films strip were conducted. The magnetic field pattern derived from the calculation is in good agreement with the stripe pattern of the experiment. Such step-edges are representative of physical imperfections that dictate the presence or absence of the stripe pattern in an anisotropic superconductor.

    Allee effects are an important component in the population dynamics of numerous species. Accounting for these Allee effects in population viability analyses generally requires estimates of low-density population growth rates, but such data are unavailable for most species and particularly difficult to obtain for large mammals. Here, we present a mechanistic modeling framework that allows estimating the expected low-density growth rates under a mate-finding Allee effect before the Allee effect occurs or can be observed. The approach relies on representing the mechanisms causing the Allee effect in a process-based model, which can be parameterized and validated from data on the mechanisms rather than data on population growth. We illustrate the approach using polar bears (Ursus maritimus), and estimate their expected low-density growth by linking a mating dynamics model to a matrix projection model. The Allee threshold, defined as the population density below which growth becomes negative, is shown to depend on age-structure, sex ratio, and the life history parameters determining reproduction and survival. The Allee threshold is thus both density- and frequency-dependent. Sensitivity analyses of the Allee threshold show that different combinations of the parameters determining reproduction and survival can lead to differing Allee thresholds, even if these differing combinations imply the same stable-stage population growth rate. The approach further shows how mate-limitation can induce long transient dynamics, even in populations that eventually grow to carrying capacity. Applying the models to the overharvested low-density polar bear population of Viscount Melville Sound, Canada, shows that a mate-finding Allee effect is a plausible mechanism for slow recovery of this population. Our approach is generalizable to any mating system and life cycle, and could aid proactive management and conservation strategies, for example, by providing a priori estimates of minimum

  9. Satellite observations of aerosol transport from East Asia to the Arctic: three case studies

    Full Text Available Vertical profiles of aerosols obtained with the CALIOP lidar onboard CALIPSO are used in conjunction with the GEOS-Chem chemical transport model and NOAA's HYSPLIT trajectory model to document three aerosol export events from East Asia to the Arctic that occurred in the year 2007. During each of these events CALIOP sampled the pollution plumes multiple times over periods of five to seven days. Meridional transport to the Arctic was rapid, taking 3–4 days and was accompanied by net diabatic heating of ~5 °C/day and precipitation in its ascending stage. Once in the Arctic transport was nearly isentropic with slow subsidence and radiative cooling at a rate of 1–1.5 °C/day. We find close agreement between modeled and observed plume in terms of length, altitude, thickness and, within the measurement uncertainties, extinction coefficient. In one event the satellite algorithm misclassifies the aerosol layer as ice clouds as a result of the relatively high depolarization ratio (0.06, likely caused by a somewhat high dust component in the aerosol mixture. The misclassification is more severe at daytime (67% of layers are misclassified than at nighttime (32%. The two most intense export events occurred in early spring within a three-week time span and are strongly related to a persisting blocking anticyclone that was located in the NW Pacific. Using 500 hPa geopotential height anomalies of these two events along with several others in 2007–2009 we develop a meteorological index that captures 40–60% of the variance of Asian transport events to the Arctic in winter and spring.

    Full Text Available Background. Antibiotic-associated diarrhea (AAD develops through the loss of normal bacterial intestinal flora. We have conducted a case-control study in order to assess whether prophylactic administration of Saccharomyces boulardii (S. boulardii prevents occurrence of AAD among adult hospitalized patients. Methods. Single-center hospital based case-control study was conducted in University Clinic “Dr Dragisa Misovic-Dedinje”, Belgrade, Serbia. Hospital records were screened in order to identify all the patients developing AAD in period January 1. 2010 – August 31. 2015. For every case, one age and gender matched control was randomly selected among patients hospitalized at the same time at the same department who were administered with antibiotics and did not develop AAD. For both cases and controls data were extracted on demographics, medical history, indication for use of antibiotics, antibiotics used, and prophylactic use of S.boulardii probiotics. The relationship between occurrence of AAD and putative risk factors were measured using the odds ratios (ORs and their 95% confidence interval (CI derived from logistic regression analysis. Results. Number of 59 cases and 59 controls were included in the study. Most of AAD cases were associated with old age (mean age of 78.05, and almost half (49.15% were hospitalized on geriatrics department. Most prescribed class of antibiotics among cases was III generation cephalosporins (50.85%, followed by fluoroquinolones (28.81% and trimethoprim-sulfamethoxazole (20.34%. Significantly more cases than controls were treated with carbapenems (16.95% vs. 5.08% respectively, p=0.04. Significantly less cases were administered with prophylactic S. boulardii probiotics (18.64% vs. 42.37% p=0.005. We identified prophylactic use of S. boulardii to act protectively against development of AAD from both univariate (OR: 0.31, 95% CI: 0.14-0.72 and multivariate analysis (OR:0.36, 95% CI: 0.14-0.80.

    We have developed a tool for measuring the evolutional stage of the space weather regional warning centers using the approach of the innovative evolution starting from the perspective presented by Figueiredo (2009, Innovation Management: Concepts, metrics and experiences of companies in Brazil. Publisher LTC, Rio de Janeiro - RJ). It is based on measuring the stock of technological skills needed to perform a certain task that is (or should) be part of the scope of a space weather center. It also addresses the technological capacity for innovation considering the accumulation of technological and learning capabilities, instead of the usual international indices like number of registered patents. Based on this definition, we have developed a model for measuring the capabilities of the Brazilian Study and Monitoring Program Space Weather (Embrace), a program of the National Institute for Space Research (INPE), which has gone through three national stages of development and an international validation step. This program was created in 2007 encompassing competence from five divisions of INPE in order to carry out the data collection and maintenance of the observing system in space weather; to model processes of the Sun-Earth system; to provide real-time information and to forecast space weather; and provide diagnostic their effects on different technological systems. In the present work, we considered the issues related to the innovation of micro-processes inherent to the nature of the Embrace program, not the macro-economic processes, despite recognizing the importance of these. During the development phase, the model was submitted to five scientists/managers from five different countries member of the International Space Environment Service (ISES) who presented their evaluations, concerns and suggestions. It was applied to the Embrace program through an interview form developed to be answered by professional members of regional warning centers. Based on the returning

    Context. Measuring star formation on a local scale is important to constrain star formation laws. It is not clear yet, however, whether and how the measure of star formation is affected by the spatial scale at which a galaxy is observed. Aims: We wish to understand the impact of the resolution on the determination of the spatially resolved star formation rate (SFR) and other directly associated physical parameters such as the attenuation. Methods: We carried out a multi-scale, pixel-by-pixel study of the nearby galaxy M 33. Assembling FUV, Hα, 8 μm, 24 μm, 70 μm, and 100 μm maps, we have systematically compared the emission in individual bands with various SFR estimators from a resolution of 33 pc to 2084 pc. Results: There are strong, scale-dependent, discrepancies of up to a factor 3 between monochromatic SFR estimators and Hα+24 μm. The scaling factors between individual IR bands and the SFR show a strong dependence on the spatial scale and on the intensity of star formation. Finally, strong variations of the differential reddening between the nebular emission and the stellar continuum are seen, depending on the specific SFR (sSFR) and on the resolution. At the finest spatial scales, there is little differential reddening at high sSFR. The differential reddening increases with decreasing sSFR. At the coarsest spatial scales the differential reddening is compatible with the canonical value found for starburst galaxies. Conclusions: Our results confirm that monochromatic estimators of the SFR are unreliable at scales smaller than 1 kpc. Furthermore, the extension of local calibrations to high-redshift galaxies presents non-trivial challenges because the properties of these systems may be poorly known.

    Full Text Available Virus-associated hemophagocytic syndrome (HPS is a potentially fatal complication of immunosuppression for transplantation. However, it presents with heterogeneous clinical symptoms (fever, disturbed consciousness, and hepatosplenomegaly and laboratory findings (pancytopenia, elevated hepatic enzyme levels, abnormal coagulation, and hyperferritinemia, impeding diagnosis. Case 1: A 39-year-old female developed fever 4 years after ABO-incompatible living-related renal transplantation. Laboratory findings revealed thrombocytopenia, elevated hepatic enzymes, Epstein-Barr virus (EBV DNA seropositivity, and hyperferritinemia. EBV-associated HPS was confirmed by bone marrow aspiration. Steroid pulse therapy and etoposide were ineffective. Disseminated intravascular coagulation resulted in multiple organ failure, and the patient died 32 days after disease onset. Case 2: A 67-year-old male was admitted with rotavirus enteritis a month after living-unrelated renal transplantation. He developed sudden-onset high fever, disturbance of consciousness, and tachypnea 8 days after admission. Laboratory findings revealed elevated hepatic enzyme levels, hyperkalemia, and hyperferritinemia. Emergency continuous hemodiafiltration ameliorated the fever, and steroid pulse therapy improved abnormal laboratory values. Varicella-zoster virus meningitis was confirmed by spinal tap. Acyclovir improved consciousness, and he was discharged 87 days after admission. Fatal virus-associated HPS may develop in organ transplant patients receiving immunosuppressive therapy. Pathognomonic hyperferritinemia is useful for differential diagnosis.

    Full Text Available Aim. Large food bits can get stuck in the esophagus and must be removed by endoscopy. In some cases, this can be difficult or unsafe. We describe a new and safe treatment for such patients. Materials and Methods. 100 consecutive patients were referred to Akershus University Hospital with impacted food in the esophagus. In 36 patients (36%, the food passed spontaneously. In 59 (92% of the remaining 64 patients, the food was removed by endoscopic intervention. In the last five patients, endoscopic removal was judged difficult or unsafe. These patients received the new treatment: one capsule Creon 10000 IU dissolved in 30 mL of Coca-Cola administered by a nasooesophageal tube four times daily for 2-3 days. Results. Of the 59 patients treated with endoscopic procedure, complications occurred in four (7%: three bleedings and one perforation of the esophagus. In five patients treated with Coca-Cola and Creon, the food had either passed or was soft after 2-3 days and could easily be removed. Conclusion. The treatment of choice of impacted food in the esophagus is endoscopic removal. In cases where this is difficult, we recommend treatment with Coca-Cola and Creon for 2-3 days before complications occur.

    Full Text Available Introduction: Public healthcare system in India suffers from poor performance mainly due to the severe shortage and high absenteeism of healthcare providers. The performance is further affected due to low productivity and competencies of the already existing healthcare providers. While management training (with a special focus on human resource issues to address the shortage to healthcare providers has gained some importance in recent past, there has been a very limited focus on how to use the exiting workforce effectively. With this backdrop, training health providers in issues pertaining to team effectiveness becomes very crucial. The case study discusses some of the dimensions of team building, as well as processes involved in performance improvement including problem identification, prioritization, and problem-solving process as demonstrated by health system improvement teams (HSIT′s. Materials and Methods: HSIT′s have been constituted and are functional at 238 secondary level facilities in Rajasthani. The case writer interacted with five HSIT′s from two districts in Rajasthan. We were able to speak to about four to five members from each team for all the five facilities. The information for the case was gathered in two ways. The first was use of an instrument on team building that was given to each member of the team to gauge their individual perception about various team building aspects. The second was with the help of group discussions that were done with all the team members for each all the five teams. All those who were present and willing to be part of the discussion were given instruments and were included in group discussions. As this was an exploratory case study, the sample size was small and, therefore, the findings from group discussion and instruments have been presented together without any quantification of the data. Results: The findings of the case study indicate moderate team empowerment. While HSIT′s were clear

    The aim of this study was to describe contextual events, abuse experiences, and disclosure processes of adolescents who presented to a hospital-based Child Advocacy Center for medical evaluation and evidentiary collection as indicated after experiencing multiple perpetrator rape during a single event (n = 32) and to compare these findings to a group of single perpetrator sexual assaults (n = 534). This study used a retrospective mixed-methods design with in-depth, forensic interviews and complete physical examinations of gang-raped adolescents. Patients ranged from 12 to 17 years (M = 14 years). Girls who experienced multiple perpetrator rape during a single event were more likely to have run away, to have drunk alcohol in the past month, and to have participated in binge drinking in the past 2 weeks. Acute presentation of these victims were rare but 30% had hymenal transections and 38% had sexually transmitted infections (STIs). Forensic interviews revealed alcohol was a common weapon used by offenders, and its use resulted in victims experiencing difficulty in remembering and reporting details for police investigation or physical and mental health care. Most victims were raped at parties they attended with people they thought they could trust, and they felt let down by witnesses who could have helped but did not intervene. Although relatively rare, multiple perpetrator rape during a single event is a type of severe sexual assault experience and has significant risks for deleterious health outcomes. These victims require health care by trained providers to diagnose physical findings, treat STIs, screen for trauma, and support victims. PMID:24933707

    Becker, Jörg; Niehaves, Björn; Krause, Andreas

    Shared services have proven to be a key element when it comes to increasing government efficiency by collaboration. Here, we seek to investigate into the shared services phenomenon in the context of government reforms. For this purpose, an interview and document analysis-based multiple case study has been conducted in Germany. The qualitative analysis covers two shared service implementations on the local government level and identifies important preconditions for shared service emergence, namely cost pressure as motive, the existence of key actors promoting the topic and the existence of prior cooperation. Moreover, it is shown that the structure of such previous cooperation determines, if shared services are being organised in a centralised (shared service centre) or decentralised format (shared service network).

    2014-03-01

    Full Text Available Three cases of Epstein-Barr virus (EBV-negative post-transplant lymphoproliferative disease that occurred 6 to 8 years after renal transplantation are reported. The patients respectively had gastric mucosa-associated lymphoid tissue lymphoma, gastric diffuse large B-cell lymphoma, and atypical Burkitt lymphoma. Absence of EBV in the tissue samples was demonstrated by both in situ hybridization for EBV early RNA and polymerase chain reaction for EBV DNA. Patients were treated with reduction in immunosuppression and combined chemotherapy plus an anti-CD20 monoclonal antibody, rituximab. Despite the reduction in immunosuppression, patients had stable renal functions without loss of graft functions. The patient with atypical Burkitt lymphoma had an abnormal karyotype, did not respond to treatment completely, and died due to disease progression. The other patients are still alive and in remission 5 and 3 years after diagnosis, respectively. EBV-negative post-transplant lymphoproliferative diseases are usually late-onset and are reported to have poor prognosis. Thus, reduction in immunosuppression is usually not sufficient for treatment and more aggressive approaches like rituximab with combined chemotherapy are required.

  4. Invasive amebiasis and ameboma formation presenting as a rectal mass: An uncommon case of malignant masquerade at a western medical center

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    A 54-year-old man presented with rectal pain and bleeding secondary to ulcerated, necrotic rectal and cecal masses that resembled colorectal carcinoma upon colonoscopy. These masses were later determined to be benign amebomas caused by invasive Entamoeba histolytica, which regressed completely with medical therapy. In Western countries, the occurrence of invasive protozoan infection with formation of amebomas is very rare and can mistakenly masquerade as a neoplasm. Not surprisingly, there have been very few cases reported of this clinical entity within the United States. Moreover, we report a patient that had an extremely rare occurrence of two synchronous lesions, one involving the rectum and the other situated in the cecum. We review the current literature on the pathogenesis of invasive E. Histolytica infection and ameboma formation, as well as management of this rare disease entity at a western medical center.

    The setting for this case study is the Dolph Briscoe, Jr. Library, University of Texas Health Science Center at San Antonio, a health sciences campus with medical, dental, nursing, health professions, and graduate schools. During 2008-2009, major renovations to the library building were completed including office space for a faculty development department, multipurpose classrooms, a 24/7 study area, study rooms, library staff office space, and an information commons. The impetus for changes to the library building was the decreasing need to house collections in an increasingly electronic environment, the need for office space for other departments, and growth of the student body. About 40% of the library building was remodeled or repurposed, with a loss of approximately 25% of the library's original space. Campus administration proposed changes to the library building, and librarians worked with administration, architects, and construction managers to seek renovation solutions that meshed with the library's educational mission.

    The aim of this study was to investigate the profiles of pathogens and patterns of antibiotic resistance of emphysematous pyelonephritis (EPN), offering recommendations for initial antibiotic treatment.Between January, 2001, and November, 2014, demographic data, presenting clinical features, management strategies, and treatment outcomes of 51 patients with EPN were retrospectively reviewed, analyzing microbiological characteristics of causative pathogens and patterns of antibiotic resistance.Overall survival rate was 90.2% (46/51). Pathogens isolated most frequently were Escherichia coli (49.0%), Klebsiella pneumoniae (19.6%), and Proteus mirabilis (17.7%). Approximately 24% of E coli isolates and 22% K pneumoniae isolates were resistant to fluoroquinolones. Improper empiric antibiotic use (P = 0.02) and third-generation cephalosporin-resistant pathogens (G3CRP) (P = 0.01) were significantly more common in cases of patient fatality. Prior hospitalization and antibiotic use within past year (P = 0.03), need for emergency hemodialysis (P = 0.03), and development of disseminated intravascular coagulation (DIC) (P = 0.03) were factors correlating significantly with microbial resistance to third-generation cephalosporins. The area under the receiver operating characteristic curve was 0.91. The cut-off point determined by the maximum Youden index for 2 of these 3 factors yielded a sensitivity of 0.8 and specificity of 0.93.Third-generation cephalosporins are recommended as initial treatment of EPN. In patients with histories of prior hospitalization and antibiotic use and in those needing emergency hemodialysis or developing DIC, carbapenem is the empiric antibiotic of choice. Patients presenting with 2 or more factors carry the highest risk of G3CRP involvement. Fluoroquinolone and gentamicin should be avoided. PMID:27227920

  8. Spectrum of central nervous system tumours-a single center histopathological review of 761 cases over 5 years

    International Nuclear Information System (INIS)

    The incidence of central nervous system (CNS) tumours has rapidly increased over the past few years. There is no accurate nationwide CNS tumour epidemiology in Pakistan that makes policy making for tumour screening and early treatment difficult. The purpose of this study was to provide the spectrum of CNS tumours in a premier diagnostic and referral centre of Pakistan. Methods: This cross-sectional study was carried out at Histopathology Department, Armed Forces Institute of Pathology over a period of 5 years. A total of 761 cases patients who were diagnosed with CNS tumours on histopathology, both benign and malignant, belonging to both genders, between the ages of 1-85 years, from 11.2009 to 31.12.2013 were included in the study. Results: Seven CNS tumour categories were as follows; tumours of neuroepithelial tissue (56.0%), tumours of the meninges (28.3%), tumour of the sellar region (2.6%), germ cell tumour (0.1), tumour of cranial and paraspinal nerves (5.4%), lymphomas and haematopoietic neoplasm (2.4%), metastatic tumours (4.9%), where histological types by age and gender showed great variability. Astrocytic tumours were the commonest neuroepithelial tumours (69.4%). Glioblastoma multiform forming the largest subtype of neuroepithelial tumours (40.4%) with a mean age at diagnosis being 47.1 years. Overall, males exceeded females in number of most of the CNS tumour types, however meningeal tumours were more frequently noted in females. Conclusions: Neuroepithelial tumours are commonest tumour and comprise more than half of all operated CNS tumours in our setup, followed by meningeal tumours. Glioblastoma multiforme is largest subtype of neuroepithelial tumour, and comprising 40.4% of all. (author)

    Quality of exposure assessment has been shown to be related to the ability to detect risk of lymphohematopoietic disorders in epidemiological investigations of benzene, especially at low levels of exposure. We set out to build a statistical model for reconstructing exposure levels for 2898 subjects from 501 factories that were part of a nested case-cohort study within the NCI-CAPM cohort of more than 110,000 workers. We used a hierarchical model to allow for clustering of measurements by factory, workshop, job, and date. To calibrate the model we used historical routine monitoring data. Measurements below the limit of detection were accommodated by constructing a censored data likelihood. Potential non-linear and industry-specific time-trends and predictor effects were incorporated using regression splines and random effects. A partial validation of predicted exposures in 2004/2005 was performed through comparison with full-shift measurements from an exposure survey in facilities that were still open. Median cumulative exposure to benzene at age 50 for subjects that ever held an exposed job (n=1175) was 509 mg/m(3) years. Direct comparison of model estimates with measured full-shift personal exposure in the 2004/2005 survey showed moderate correlation and a potential downward bias at low (<1 mg/m(3)) exposure estimates. The modeling framework enabled us to deal with the data complexities generally found in studies using historical exposure data in a comprehensive way and we therefore expect to be able to investigate effects at relatively low exposure levels.

    We present the results of observations of blazar PKS 1510-089 with the Herschel Space Observatory PACS and SPIRE instruments, together with multiwavelength data from Fermi/LAT, Swift, SMARTS and SMA. The source was found in a quiet state, and its far-infrared spectrum is consistent with a power-law with a spectral index of alpha ~ 0.7. Our Herschel observations were preceded by two 'orphan' gamma-ray flares. The near-infrared data reveal the high-energy cut-off in the main synchrotron component, which cannot be associated with the main gamma-ray component in a one-zone leptonic model. This is because in such a model the luminosity ratio of the External-Compton and synchrotron components is tightly related to the frequency ratio of these components, and in this particular case an unrealistically high energy density of the external radiation would be implied. Therefore, we consider a well-constrained two-zone blazar model to interpret the entire dataset. In this framework, the observed infrared emission is asso...

    Non-thermal radiation has been predicted within bow shocks around runaway stars by recent theoretical works. We present X-ray observations towards the runaway stars $\\zeta$ Oph (Chandra and Suzaku) and BD+433654 (XMM-Newton) to search for the presence of non-thermal X-ray emission. We found no evidence of non-thermal emission spatially coincident with the bow shocks, nonetheless, diffuse emission is detected in the vicinity of $\\zeta$ Oph. After a careful analysis of its spectral characteristics we conclude that this emission has a thermal nature with a plasma temperature of $T \\approx 2 \\times10^{6}$ K. The cometary shape of this emission seems to be in line with recent predictions of radiation-hydrodynamic models of runaway stars. The case of BD+433654 is puzzling as non-thermal emission has been reported in a previous work for this source.

  13. Second malignancies following Hodgkin's disease treatment in Tunisia. Retrospective study of 26 cases observed at the institute Salah-Azaiz

    International Nuclear Information System (INIS)

    Purpose. - To collect second cancers in patients treated for Hodgkin disease (HD) during adolescence and young adulthood at Salah Azaiz Institute of Tunis. Method and patients. - We consider as second cancer all tumours other than HD observed in patients after treatment for HD. Results. - Twenty-five patients among 614 treated for HD between 1975 and 1991 developed 26 secondary tumours (4.2%). There were 17 males and eight females (sex ratio 2:1). Mean age at the diagnosis of HD was 32.5 years (12-56). HD was stage 11 (eight cases), stage 111 (14) and stage IV in three. The first treatment was combined chemotherapy and radiotherapy in 22 cases and only chemotherapy in three cases (stage IV). Radiotherapy was delivered with Cobalt 60 by large fields. Mean dose was 41.3 Gy (2 Gy/fraction in 21 and 3.3 in one). Chemotherapy was MOPP (13), MOPP and vinblastine (four), MOPP-ABVD (five), ABVD (two) and vinblastine only in one. Mean delay of second tumours was 114.5 months (40-276). There was five acute myeloid leukaemia, two digestive non-Hodgkin lymphomas, five nodal high-grade lymphomas, three breast cancers (one in man associated with thyroid cancer), five lung cancers (three non-small cell and two of small cell type), two gastric tumours and one rectal cancer, one synovialosarcoma of the knee and one malignant Schwannoma of the neck. Median survival was 12.5 months (2-18). Twenty-one patients died and four are still alive with 8, 12, 24 and 48 months of follow-up. Conclusion. - Second cancer risk after treatment for HD is not low. Risk factors and preventive strategies are discussed. (authors)

    Immunoglobulin-G4 (IgG4)-related disease (IgG4RD) is a fibro-inflammatory disorder characterized by tissue-infiltrating IgG4 plasma cells, and, often, high serum IgG4. Several autoimmune, infectious, or proliferative conditions mimic IgG4RD. Erdheim-Chester disease (ECD) is a rare non-Langerhans cell histiocytosis, characterized by foamy histiocytic infiltration, fibrosis, and chronic inflammation. ECD and IgG4RD manifestations may overlap.A patient presented with huge fibrous retroperitoneal masses causing compression on neighboring structures; the case posed the challenge of the differential diagnosis between IgG4RD and ECD mainly because of a prominent serum and tissue IgG4 response.Retroperitoneal biopsy led to the diagnosis of ECD; the V600E BRAF mutation was found. Treatment with the BRAF inhibitor vemurafenib was started.Treatment failed to induce mass regression and the patient died after 3 months of therapy. Prompted by this case, we examined serum and tissue IgG4 in a series of 15 ECD patients evaluated at our center, and found that approximately one-fourth of the cases have increased IgG4 in the serum and often in the tissue.The differential diagnosis between IgG4RD and ECD can be challenging, as some ECD patients have prominent IgG4 responses. This suggests the possibility of common pathogenic mechanisms between ECD and IgG4RD. PMID:27227923

  16. The Role of Large-Coherent-Eddy Transport in the Atmospheric Surface Layer Based on CASES-99 Observations

    The analysis of momentum and heat fluxes from the Cooperative Atmosphere-Surface Exchange Study 1999 (CASES-99) field experiment is extended throughout the diurnal cycle following the investigation of nighttime turbulence by Sun et al. (J Atmos Sci 69:338-351, 2012). Based on the observations, limitations of Monin-Obukhov similarity theory (MOST) are examined in detail. The analysis suggests that strong turbulent mixing is dominated by relatively large coherent eddies that are not related to local vertical gradients as assumed in MOST. The HOckey-Stick Transition (HOST) hypothesis is developed to explain the generation of observed large coherent eddies over a finite depth and the contribution of these eddies to vertical variations of turbulence intensity and atmospheric stratification throughout the diurnal cycle. The HOST hypothesis emphasizes the connection between dominant turbulent eddies and turbulence generation scales, and the coupling between the turbulence kinetic energy and the turbulence potential energy within the turbulence generation layer in determining turbulence intensity. For turbulence generation directly influenced by the surface, the HOST hypothesis recognizes the role of the surface both in the vertical variation of momentum and heat fluxes and its boundary effect on the size of the dominant turbulence eddies.

    Full Text Available Background: Chronic subdural hematoma (CSDH is frequent pathology in neurosurgical practice. The aim of this study is to present the first series of patients with CSDH, who got surgically treated in Clinic of Neurosurgery, University Clinical Center of Kosovo. Materials and Methods: This is a retrospective study that included 137 patients with CSDH who had been treated during the period 2008-2012. The data were collected and analyzed from the archives and protocols of the University Clinical Center of Kosovo. Patients were analyzed in many aspects such as age, gender, etiological factors, clinical features, localization, diagnoses, methods of surgical interventions, recurrences and mortality of patients. Results: From 137 patients with CSDH, 106 (77.3% were males and 31 (22.7% females. Average age of patients was 62.85 years. Analyzed according to the decades, the highest number of causes with CSDH was between 70 and 79 years (46%. The head trauma has been responsible for CSDH in 88 patients (64.3%, while the main symptom was headache (92 patients or 67.1%. One burr-hole trepanation with closed drainage system has been used in majority of cases (in 101 patients or 73.7%. The recurrence of CSDH was 6.5%, whereas mortality 2.9%. Conclusion: CSDH is more common in elderly patients. The male-female ratio is 3.4:1. Like other authors we also think that treatment with one burr-hole and drainage is a method of choice, because of its simplicity and safety.

    Full Text Available Background: Breast cancer is now the most common cancer in many parts of India and the incidence varies from 12 to 31/100000, and is rising. Locally advanced breast cancer (LABC accounts for 30 - 35% of all cases of breast cancers in India. LABC continues to present a challenge and imposes a major health impact in our country. Materials and Methods: We carried out a analysis of our LABC patients who received neoadjuvant chemotherapy (NACT at our hospital over a 10-year period, from January 1995 to December 2004. We analyzed the response to NACT, disease-free survival (DFS, and overall survival (OS. Results: Patients with stages IIIA, IIIB, and IIIC were included. LABC comprised of 26.24% (609 patients of new patients. One hundred and twenty-eight (31.1% patients received NACT. Median age was 48 years and estrogen receptor was positive in 64%. Chemotherapy protocol was an FEC (5-Fluorouracil, Epirubicin, Cyclophosphamide regimen in the following doses: Cyclophosphamide 600 mg/m2, 5-FU 600 mg/m2, and Epirubicin 75 mg/m2 given every three weeks, six doses, followed by modified radical mastectomy (MRM and locoregional radiotherapy. The overall response rate (complete response (CR + partial response (PR was 84.4%, clinical CR (cCR was 13.3% and pathological CR (pCR was 7.8%. Median DFS and OS were 33 and 101 months, respectively. The disease-free survival (DFS and overall survival (OS at five years were 41 and 58%, respectively. Conclusions: This study analyzes the outcome in patients who received NACT, in the largest number of LABC patients from a single center in India, and our results are comparable to the results reported from other centers.

  20. From observation to understanding: Approach to analysis of wear mechanisms, Case of RCCAs and CRDM latch arms

    International Nuclear Information System (INIS)

    Component wear can affect the ability of a component to fulfill its required function. For a designer or user, it is reasonable to expect possible wear occurrence as soon as parts are in relative motion. It is less obvious to extend this possibility to motions with small or very small amplitudes and loads. However, it has to be admitted that such cases exist. It then becomes imperative to determine the wear mechanisms so that the lifetime of the components and the optimum date of their replacement can be predicted or the degradation can be remedied. For this purpose, standard and widely accepted practice is to carry out simulator tests. Through examples of wear from nuclear reactor components such as the RCCAs (Rod Cluster Control Assembly) and the CRDM (Control Rod Drive Mechanism) latch arms, an approach for understanding the wear mechanisms and controlling their effects can be undertaken. Cases of wear have been observed on real-life parts, but the first simulator tests have shown deviations from in-reactor behaviour. Comparative examination of the wear facies of actual parts which have operated in reactor or simulators, both control rods and CRDM latch arms, was the key starting point for a new analytical approach, incorporating the formulation of wear mechanism hypotheses which can account for the observed facies. Expert assessment thus highlighted the importance of the environment by revealing that the wear featured a large component linked to friction-assisted corrosion. By including this tribo-corrosion aspect, it became possible to reach understanding of the mechanisms and account for the wear observed in reactor and on simulators. Further well-controlled simulator tests then made it possible to verify the importance of the tribo-corrosion processes in a pressurized water medium. Analysis of the physical chemical behaviour of the original materials (austenitic stainless steel) also explains why these surface modifications limit or remedy wear

    2016-07-01

    In a randomized clinical trial, Geriatric Resources for Assessment and Care of Elders (GRACE), a model of care that works in collaboration with primary care providers (PCPs) and patient-centered medical homes to provide home-based geriatric care management focusing on geriatric syndromes and psychosocial problems commonly found in older adults, improved care quality and reduced acute care use for high-risk, low-income older adults. To assess the effect of GRACE at a Veterans Affairs (VA) Medical Center (VAMC), veterans aged 65 and older from Marion County, Indiana, with PCPs from four of five VAMC clinics who were not on hospice or dialysis were enrolled in GRACE after discharge home from an acute hospitalization. After an initial home-based transition visit to GRACE enrollees, the GRACE team returned to conduct a geriatric assessment. Guided by 12 protocols and input from an interdisciplinary panel and the PCP, the GRACE team developed and implemented a veteran-centric care plan. Hospitalized veterans from the fifth clinic, who otherwise met enrollment criteria, served as a usual-care comparison group. Demographic, comorbidity, and usage data were drawn from VA databases. The GRACE and comparison groups were similar in age, sex, and burden of comorbidity, although predicted risk of 1-year mortality in GRACE veterans was higher. Even so, GRACE enrollment was associated with 7.1% fewer emergency department visits, 14.8% fewer 30-day readmissions, 37.9% fewer hospital admissions, and 28.5% fewer total bed days of care, saving the VAMC an estimated $200,000 per year after program costs during the study for the 179 veterans enrolled in GRACE. Having engaged, enthusiastic VA leadership and GRACE staff; aligning closely with the medical home; and accommodating patient acuity were among the important lessons learned during implementation.

    PURPOSE: To describe cases of postoperative endophthalmitis in the European Society of Cataract & Refractive Surgeons (ESCRS) study of the prophylaxis of endophthalmitis, compare characteristics of unproven cases and cases proven by culture or polymerase chain reaction, and compare the characteristics with those in other reported series. SETTING: Twenty-four ophthalmology units in Austria, Belgium, Germany, Italy, Poland, Portugal, Spain, Turkey, and the United Kingdom. METHODS: Univariable and multivariable logistic regression models were used to analyze data for statistical association of signs and symptoms in cases with proven or unproven endophthalmitis. Specific data describing characteristics of the cases were compared between the 2 types of cases. RESULTS: Data from 29 endophthalmitis cases were analyzed. Swollen lids and pain were statistically associated with proven cases of endophthalmitis on univariable regression analysis. Multivariable analysis indicated that swollen lids and an opaque vitreous were associated with proven cases. Five cases of endophthalmitis occurred in the cefuroxime-treated groups. No case of streptococcal infection occurred in the cefuroxime-treated groups. However, cases of infection due to streptococci showed striking differences in visual acuity and were associated with earlier onset. Characteristics in the 29 cases parallel results in previous studies, such as the Endophthalmitis Vitrectomy Study, although the addition of a control group in the ESCRS study elicited additional findings. CONCLUSION: Swollen lids, pain, and an opaque vitreous were statistically associated with proven endophthalmitis cases in the ESCRS study.

    Full Text Available Irrational use of antibiotics may lead to increase morbidity and mortality. Monitoring of antibiotics was required to support government programs, especially The Department of Health stating the use of antibiotics for non-respiratory diseases pneumonia was less than 20%. The evaluation of antibiotics use in this research applied ATC / DDD methods and DU 90%. The antibiotic used for non-pneumonia ARI were 9 types and the antibiotics contained DU 90% were three types namely amoxicillin 500 mg (2,723 DDD/1000 patients-year, ciprofloxacin (0,378 DDD/1000 patients-day and cefadroxil (0,202 DDD/1000 patients-day. Quantitative data analysis using the ATC / DDD indicated that the most used antibiotic was amoxicillin (500 mg 2723 DDD / 1000 patients-day and the least was amoxicillin (125 mg / 5 ml 1.5 DDD / 1000 patients-day. The effects of short-term use of antibiotic prescribing in primary medical care could increase the resistance. Qualitative studies were needed to determine the pattern of irrational antibiotic use in community health service center and to develop the intervention model.

    Based on empirical evidence from a free word order language (German) we propose a fundamental revision of the principles guiding the ordering of discourse entities in the forward-looking centers within the centering model. We claim that grammatical role criteria should be replaced by indicators of the functional information structure of the utterances, i.e., the distinction between context-bound and unbound discourse elements. This claim is backed up by an empirical evaluation of functional centering.

    Among the atmospheric emission sources, wildfires are episodic events characterized by large spatial and temporal variability. Therefore, accurate information on fire gaseous and aerosol emissions for specific regions and seasons is critical for air quality forecasts. The Spinning Enhanced Visible and Infrared Imager (SEVIRI) in geostationary orbit provides fire observations over Africa and the Mediterranean with a unique temporal resolution of 15 min. It thus resolves the complete fire life cycle and captures the fires' peak intensities, which is not possible in MODIS-based fire emission inventories like GFAS. We evaluate two different operational Fire Radiative Power (FRP) products derived from SEVIRI, by studying the case of a large forest fire in Antalya, Turkey, in July-August 2008. The EUMETSAT LSA SAF product has higher FRP values during the fire episode than the WF_ABBA product. It is also in better agreement with the co-located, gridded MODIS FRP. Both products miss small fires that frequently occur in the region and are detected by MODIS. Emissions are derived from the FRP products. They are used along-side GFAS emissions in smoke plume simulations with WRF and the Community Multiscale Air Quality model (CMAQ). Comparisons with MODIS AOT and IASI CO and NH3 observations show that including the diurnal variability of fire emissions improves the spatial distribution and peak concentrations of the simulated smoke plumes associated to the large fire. They also show a large discrepancy between the currently available operational FRP products, with the LSA SAF one being the most appropriate.

    Mixed phase clouds contain both ice particles and super-cooled cloud water droplets in the same volume of air. Currently, one of the main challenges is to observe and understand how ice particles grow by interacting with liquid water within the mixed-phase clouds. In the mid latitudes this process is one of the most efficient processes for precipitation formation. The case study presented here is based on observations obtained with the Transportable Atmospheric RAdar (TARA), S-band precipitation radar profiler, from Delft University of Technology during the Analysis of the Composition of mixed-phase Clouds with Extended Polarization Techniques campaign (ACCEPT) at Cabauw The Netherlands, autumn 2014. The high temporal (3 seconds) and spatial resolutions (21 m) as well as the Doppler and polarimetric capabilities of TARA are used to estimate size and shape information of the measured hydrometeors. In addition, the unique 3 beam configuration of TARA provides 3-D dynamical information within the cloud system. Based on the dynamical information it is possible to retrieve the fall steak signatures of falling ice particles within radar measurements. Those signatures allow to follow particle population from their generation (at cloud top) to their disintegration. So this technique offers a new perspective for cloud microphysical evolution studies. Using retrieved profiles of radar moments and spectral information along the fall streaks, microphysical information are estimated leading to a better understanding of the influence of super-cooled liquid layer on ice crystals growth under ambient conditions. A synergetic setup of instruments during the ACCEPT campaign was used to liquid layers within the cloud system. So several type of ice crystal growth processes could be detected and will be presented and discussed.

    We aimed to describe the use of venovenous extracorporeal carbon dioxide removal (ECCO2R) in patients with hypercapnic respiratory failure. We performed a retrospective case note review of patients admitted to our tertiary regional intensive care unit and commenced on ECCO2R from August 2013 to February 2015. Fourteen patients received ECCO2R. Demographic data, physiologic data (including pH and partial pressure of carbon dioxide in arterial blood [PaCO2]) when starting ECCO2R (t = 0), at 4 hourly intervals for the first 24 hours, then at 24 hour intervals until cessation of ECCO2R, and overall outcome were recorded. Patients are reported separately depending on whether the indication for ECCO2R was an exacerbation of chronic obstructive pulmonary disease (COPD; n = 5), or acute respiratory distress syndrome (ARDS) and persisting hypercapnoea (n = 9). Patients were managed with ECCO2R (Hemolung, ALung Inc, Pittsburgh, PA). Median duration of ECCO2R was 5 days. Four complications related to ECCO2R were reported, none resulting in serious adverse outcomes. Ten patients were discharged from intensive care unit (ICU) alive. A statistically significant improvement in pH (p = 0.012) was demonstrated. Our observational series of ECCO2R shows that this technique can be safely used to achieve therapeutic goals in patients requiring lung protection, and in COPD, in line with current publications in this area.

    Titanium and its alloys are widely used in prosthetic dentistry, due to their biocompatibility, excellent mechanical and anti-corrosion behavior. However, delayed fracture of dental prosthetics is frequently encountered. Mechanisms leading to fracture are not generic but are strongly related to the particular environmental (quality of biological fluids) and mechanical loading conditions (mastication habits, presence of prosthetic metallic/ceramic components) in the patients' oral cavity. In this study, a commercially pure titanium implant-screw system has failed after 15 years of operation in the oral cavity of an old female. The system was retrieved in three pieces: the upper part of the implant, part of the abutment screw, and the apical part of the implant to which a part of the screw was embedded. This is considered as a rare case, where the whole dental assembly was retrieved after fracture allowing the extensive fractographic analysis of the conjugate pieces and the establishment of a thorough in-vivo failure scenario. Scanning electron microscopy observations performed on all three retrieved parts indicated a synergistic effect of distinct mechanisms, which led to total failure under extrinsic common fatigue loading. The principal mechanism was the propagation of a main crack, which was previously initiated in the body of the implant and affected by a wedging mechanism due to Ca/P aggregates developed within the crack. Because of the strong fixation between the implant and the abutment screw, this main crack was transferred to the latter causing eventually total failure of the assembly. PMID:18837452

    Gastrointestinal involvement is rare in Behçet's syndrome (BS) patients from the Mediterranean basin. We report the demographic and disease characteristics, treatment modalities, and outcome of patients with gastrointestinal involvement in BS (GIBS).We retrospectively reviewed the charts of all BS patients in our BS clinic with a diagnosis of GIBS. Patients were invited to the clinic to assess their outcome.Among 8763 BS patients, we identified 60 with GIBS (M/F: 32/28, mean age at diagnosis: 34 ± 10, mean follow-up: 7.5 ± 4 years), after excluding 22 patients with mimicking symptoms. Six (10%) had juvenile-onset BS. The most common intestinal localization was ileocecal region (36/59, 61%) mainly as big oval ulcer/s. Initial treatment was azathioprine for moderate to severe (n = 37) and 5-ASA for mild cases (n = 16). Anti-TNFs and/or thalidomide provided remission in 12 of 18 (67%) refractory patients. Emergency surgery was required in 22 patients. Nine patients did not receive postoperative immunomodulators and 8 relapsed. Overall, 48 of 60 (80%) patients were in remission (29/48 without treatment) at the time of survey. Three recently treated and 2 refractory patients were still active, 3 had died due to non-GI-related reasons, and 4 were lost to follow-up.Careful evaluation for excluding mimickers is important during the diagnosis of GIBS. Azathioprine seems to be a good choice as first-line treatment with high remission rates and few adverse events. Thalidomide and/or TNF-alpha antagonists may be preferred in resistant cases. Surgery may be required for perforations or massive bleeding, and postoperative immunosuppressive treatment is necessary for preventing postoperative recurrences. PMID:27100417

    We present survey data of the NH3 (J, K) = (1, 1)--(6, 6) lines, simultaneously observed with the Tsukuba 32-m telescope, in the main part of the central molecular zone of the Galaxy. The total number of on-source positions was 2655. The lowest three transitions were detected with S/N > 3 at 2323 positions (93% of all the on-source positions). Among 2323, the S/N of (J, K ) = (4, 4), (5, 5), and (6, 6) exceeded 3.0 at 1426 (54%), 1150 (43%), and 1359 (51%) positions, respectively. Simultaneous observations of the lines enabled us to accurately derive intensity ratios with less systematic errors. Boltzmann plots indicate there are two temperature components: cold ($\\sim$ 20 K) and warm ($\\sim$ 100 K). Typical intensity ratios of Tmb(2,2)/Tmb(1,1), Tmb(4,4)/Tmb(2,2), Tmb(5,5)/Tmb(4,4), and Tmb(6,6)/Tmb(3,3) were 0.71, 0.45, 0.65, and 0.17, respectively. These line ratios correspond to diversity of rotational temperature, which results from mixing of the two temperature components.

    During the 15 years that the U.S. Environmental Protection Agency (EPA) has supported university-based research centers, there have been many changes in mission, operating style, funding level, eligibility, and selection process. Even the definition of the term {open_quotes}research center{close_quotes} is open to debate. Shifting national priorities, political realities, and funding uncertainties have powered the evolution of research centers in EPA, although the agency`s basic philosophy on the purpose and value of this approach to research remains essentially unchanged. Today, EPA manages 28 centers, through the Office of Exploratory Research. These centers are administered under three distinct programs. Each program has its own mission and goals which guide the way individual centers are selected and operated. This paper will describe: (1) EPA`s philosophy of reserach centers, (2) the complicated history of EPA research centers, (3) coordination and interaction among EPA centers and others, (4) opportunities for collaboration, and (5) plans for the future.

    @@Repeated respiratory tract infection is a frequently-occurring disease during childhood. At present, western medicine doctors generally adopt anti-infectives and immunomodulators to treat the disease, while traditional Chinese medicine doctors mainly administer decoction of Chinese herbs. The authors treated 46 cases of repeated respiratory tract infection from March 1990 to April 1996 by applying mild-moxibustion over points on the back with satisfactory therapeutic results. A report follows. Clinical Data All the 86 cases were outpatients in our hospital with duration of common cold for over 10 days and characterized by relapse of respiratory tract infection. There were over 7-time relapse of respiratory tract infection on each case within a year. Eighty-six cases were randomly divided into treatment group (46 cases) and control group (40 cases). Of the 46 cases in the treatment group, 22 were boys and 24 girls. 17 cases (36.9%) were 6 months to 4 years old, 18 (39.1%) 4 to 6 years, and 11 (23.9%) 6 to 12 years. Among the 40 cases in the control group, 19 cases were boys and 21 girls.

  18. First observation of intra-5f fluorescence from an actinyl center: Np(VI) near-IR emission in Cs2U(Np)O2Cl4

    International Nuclear Information System (INIS)

    Fluorescence from an excited 5f state of Np(VI) has been observed in the doped impurity system Cs2U(Np)O2Cl4. This is the first intra-5f fluorescence transition that has been detected at room temperature in a condensed-phase system with an actinyl (An(VI)O22+) core, and it is a rare example of fluorescence of any kind from non-uranyl ions of this type. The emission originates from an excited state approximately 6890cm-1 above the ground state. Its emission spectrum and fluorescence lifetime at 295K will be discussed. Vibronic structure in the emission spectrum is assigned based on comparison with the detailed analysis of the absorption spectra published by Denning et al

    Objective: To observe the therapeutic effect of medicine-separated moxibustion for primary dysmenorrhea and its influence on plasma hormone level. Methods: Ninety-six patients suffering from primary dysmenorrhea were randomly and evenly divided into treatment group treated with medicine-separated moxibustion of Shenque (神阙CV 8, 3-5 cones every time, beginning 1 week before onset of menstruation and stopping on the 3rd day after onset, with 10 sessions being a therapeutic course, 3 courses all together), and control group treated with oral administration of Yueyueshu (月月舒menstruation-smoothing granule, 10 g/time, b.i.d, 3 courses altogether). Menses prostaglandin E2 (PGF2α) and plasma oxytocin (OT) during menstruation were determined by radioimmunoassay. Results: After the treatment, of the two 48 cases in treatment and control groups, 18 and 5 were cured, 24 and 9 had marked improvement in their symptoms, 6 and 26 had improvement, 0 and 8 failed in the treatment, with the total effective rates being 100.0% and 83.3% respectively, the therapeutic effect of treatment group was markedly superior to that of control group (P<0.05). After the treatment, the contents of menses PGF2α in treatment group and plasma OT in both groups were significantly lower than those of pre-treatment (P<0.01). The therapeutic effect of moxibustion was significantly better than that of medication in lowering plasma OT. Conclusion: Medicine-separated moxibustion works well in treating primary dysmenorrhea, and moxibustion induced decrease of menses PGF2α and plasma OT may contribute to its effect in relieving dysmenorrhea.

    Knowledge of Terrestrial Water Storage (TWS) can provide valuable information that can be used to improve our understanding of the hydrological cycle and the impact of extreme climate events. Global TWS observations are currently only available from the Gravity Recovery And Climate Experiment satellite mission (GRACE) at monthly time scales. In this study, we present a new approach to derive the sub-monthly TWS variation over a regularly inundated area by using MODIS reflectance data in addition to GRACE solutions. In the "training" phase, monthly TWS are computed from filtered GRACE solutions. A signal restoration method is applied to correct for signal leakage caused by filtering. In parallel, a time-series of mean monthly inundated area estimates is computed based on the Normalized Difference Water Index (NDWI), derived from MODIS data. The training phase completes by finding an empirical relationship between the inundated area and the GRACE-based TWS variations, using a regression analysis. Then, the estimated parameters can be used to convert inundated area estimates into TWS variations without a further need in GRACE data. This approach has 3 major advantages over the usage of GRACE data alone. First, it can be used to cross-validate GRACE and MODIS reflectance data in order to identify and eliminate unreliable estimates. Second, it can provide sub-monthly (e.g., 8-day) TWS variations without loss of spatial resolution. Lastly, it can be used to fill gaps in TWS estimates based on GRACE data and to extend the time-series of TWS estimates beyond the time interval when GRACE data are available. The methodology is demonstrated using the Tonlé Sap floodplain located in Central Cambodia as a test case. The analysis shows an excellent agreement between the 8-day NDWI-based TWS estimates averaged over monthly intervals and the GRACE-based monthly TWS variations. The approach developed would have similar application in other areas that experience regular large

    Grassland ecosystem is critical for survival of herbivores and plays an important role in conservation and management of wildlife. These habitats are widely studied for various issues, including biodiversity, biomass assessment, carrying capacity, etc. Woody species ingression in grasslands is one such important aspect that needs critical attention in protected area as this leads to shrinking of grasslands habitat. This study presents a case of Ronda grassland in Kanha National Park - a well-known protected area in India, known for its herbivore diversity and hard-ground Barasingha (Rucervus duvaceli branderi), in particular. Long-term satellite observation for five decades was carried out to understand spatio-temporal changes. Declassified Corona satellite data, aerial photographs along with satellite datasets in the subsequent period were utilised for this study. The study revealed that 88 ha (16% of Ronda and surrounding) have been ingressed during 1962-2011, in and around Ronda grassland of Kanha National Park. Rates of ingression on linear transects were found to be 60-120 m per decade. Field studies and NDVI analysis along the edge of grassland pixels as well as inside region using 1972 as baseline data, indicated woody vegetation replacing area of grassland. It was noted that Butea monosperma is invading more than other species in Ronda grassland, particularly along the stream where moisture availability is higher. Grassland habitats in Kanha are thus shrinking and thus leading to reduction in the area available for herbivore population which has increased in recent years. This can lead to severe impact on carrying capacity of these grasslands.

    According to the clinical experience of professor Shan Zhaowei (单兆伟), the author has successfully developed Qingyou Yangwei Capsule (清幽养胃胶囊capsules for eliminating pyrolic Helicobacterium and nourishing the stomach) for treating the gastritis. Clinical research has shown that the capsule has a good curative effect on chronic gastritis related to pyrolic Helicobacterium. Among the 53 cases in the treatment group, clinical observation showed cure in 6 cases, obvious effect in 18 cases, effect in 24 cases, no effect on 5 cases, with a total effective rate of 90.5%. Of the 50 cases in the control group, cure was found in 5 cases, obvious effect in 13 cases, effect in 20 cases, no effect in 12 cases, the total effective rate being 76%. The total effective rate in the treatment group was higher than that in the control group. The rate of eliminating pyrolic Helicobacterium in the treatment group was 66.04%, similar to that in the control group. In a follow-up visit 6 months later, the recurrence rate in the treatment group was 13.33%, obviously lower than that of 41.66% in the control group.

    Full Text Available Brittany H Eghaneyan,1 Katherine Sanchez,2 Diane B Mitschke2 1Department of Psychiatry, UT Southwestern Medical Center, Dallas, TX, USA; 2School of Social Work, The University of Texas at Arlington, Arlington, TX, USA Background: The collaborative care model is a systematic approach to the treatment of depression and anxiety in primary care settings that involves the integration of care managers and consultant psychiatrists, with primary care physician oversight, to more proactively manage mental disorders as chronic diseases, rather than treating acute symptoms. While collaborative care has been shown to be more effective than usual primary care in improving depression outcomes in a number of studies, less is known about the factors that support the translation of this evidence-based intervention to real-world program implementation. The purpose of this case study was to examine the implementation of a collaborative care model in a community based primary care clinic that primarily serves a low-income, uninsured Latino population, in order to better understand the interdisciplinary relationships and the specific elements that might facilitate broader implementation. Methods: An embedded single-case study design was chosen in order to thoroughly examine the components of one of several programs within a single organization. The main unit of analysis was semi-structured interviews that were conducted with seven clinical and administrative staff members. A grounded theory approach was used to analyze the interviews. Line-by-line initial coding resulted in over 150 initial codes, which were clustered together to rebuild the data into preliminary categories and then divided into four final categories, or main themes. Results: Four unique themes about how the implementation of a collaborative care model worked in this setting emerged from the interviews: organizational change, communication, processes and outcomes of the program, and barriers to

    Full Text Available Abstract Background The to date evidence for a dose-response relationship between physical workload and the development of lumbar disc diseases is limited. We therefore investigated the possible etiologic relevance of cumulative occupational lumbar load to lumbar disc diseases in a multi-center case-control study. Methods In four study regions in Germany (Frankfurt/Main, Freiburg, Halle/Saale, Regensburg, patients seeking medical care for pain associated with clinically and radiologically verified lumbar disc herniation (286 males, 278 females or symptomatic lumbar disc narrowing (145 males, 206 females were prospectively recruited. Population control subjects (453 males and 448 females were drawn from the regional population registers. Cases and control subjects were between 25 and 70 years of age. In a structured personal interview, a complete occupational history was elicited to identify subjects with certain minimum workloads. On the basis of job task-specific supplementary surveys performed by technical experts, the situational lumbar load represented by the compressive force at the lumbosacral disc was determined via biomechanical model calculations for any working situation with object handling and load-intensive postures during the total working life. For this analysis, all manual handling of objects of about 5 kilograms or more and postures with trunk inclination of 20 degrees or more are included in the calculation of cumulative lumbar load. Confounder selection was based on biologic plausibility and on the change-in-estimate criterion. Odds ratios (OR and 95% confidence intervals (CI were calculated separately for men and women using unconditional logistic regression analysis, adjusted for age, region, and unemployment as major life event (in males or psychosocial strain at work (in females, respectively. To further elucidate the contribution of past physical workload to the development of lumbar disc diseases, we performed lag

    Data Center facilities, prevalent in many industries and institutions are essential to California's economy. Energy intensive data centers are crucial to California's industries, and many other institutions (such as universities) in the state, and they play an important role in the constantly evolving communications industry. To better understand the impact of the energy requirements and energy efficiency improvement potential in these facilities, the California Energy Commission's PIER Industrial Program initiated this project with two primary focus areas: First, to characterize current data center electricity use; and secondly, to develop a research ''roadmap'' defining and prioritizing possible future public interest research and deployment efforts that would improve energy efficiency. Although there are many opinions concerning the energy intensity of data centers and the aggregate effect on California's electrical power systems, there is very little publicly available information. Through this project, actual energy consumption at its end use was measured in a number of data centers. This benchmark data was documented in case study reports, along with site-specific energy efficiency recommendations. Additionally, other data center energy benchmarks were obtained through synergistic projects, prior PG&E studies, and industry contacts. In total, energy benchmarks for sixteen data centers were obtained. For this project, a broad definition of ''data center'' was adopted which included internet hosting, corporate, institutional, governmental, educational and other miscellaneous data centers. Typically these facilities require specialized infrastructure to provide high quality power and cooling for IT equipment. All of these data center types were considered in the development of an estimate of the total power consumption in California. Finally, a research ''roadmap'' was developed

    Upcoming multiyear satellite lidar aerosol observations need strong support by a worldwide ground-truth lidar network. In this context the question arises as to whether the ground stations can deliver the same results as obtained from space when the Klett formalism is applied to elastic backscatter lidar data for the same aerosol case. This question is investigated based on simulations of observed cases of simple and complex aerosol layering. The results show that the differences between spaceborne and ground-based observations can be as large as20% for the backscatter and extinction coefficients and the optimum estimates of the column lidar ratios. In cases with complex aerosol layering, the application of the two-layer approach can lead to similar results (space, ground) and accurate products provided that horizontally homogeneous aerosol conditions are given

    In the past decade high resolution measurements in the infrared employing adaptive optics imaging on 10m telescopes have allowed determining the three dimensional orbits stars within ten light hours of the compact radio source at the center of the Milky Way. These observations show the presence of a three million solar mass black hole in Sagittarius A* beyond any reasonable doubt. The Galactic Center thus constitutes the best astrophysical evidence for the existence of black holes which have ...

    In the present paper, the authors report their results about clinical treatment of 600 cases of mastitis with acupuncture plus TDP irradiation. Main points Tanzhong (CV 17), Quchi (LI L1) and Jiaji (EX-B 2) were punctured, supplemented with other acupoints according to the concrete symptoms and signs and TDP irradiation for 30min. For example, in the treatment of mastitis patients with high fever, bilateral Hegu (LI 4) and Taichong (LR 3)were punctured in combination with pricking blood and cupping methods. After 1 - 10 sessions of treatment (once daily), all the 600 cases were effective, with 510 cases (85%) being cured, 83 cases ( 13.8% ) remarkably effective,and with 7 cases ( 1.2 % ) effective.

    Full Text Available Abstract Background Autism is a heritable developmental disorder of communication and socialization that has not been well studied in Hispanic populations. Therefore, we are collecting and evaluating all possible cases of autism from a population isolate in the Central Valley of Costa Rica (CVCR for a clinical and genetic study. Methods We are assessing all subjects and parents, as appropriate, using the newly translated Spanish versions of the Autism Diagnostic Interview-Revised (ADI-R and the Autism Diagnostic Observation Schedule (ADOS as well as tests of intelligence and adaptive behavior. Detailed obstetric and family medical/psychiatric histories are taken. All cases are tested for Fragile X and will be extensively evaluated for cytogenetic abnormalities. Results To date we have obtained clinical evaluations on over 76 cases of possible autism referred to our study and report data for the initial 35 complete cases. The mean age of the probands is 6.7 years, and 31 of the 35 cases are male. Twenty-one of the cases have IQs Conclusion Diagnostic data gathered on cases of autism in the CVCR using Spanish versions of the ADI-R and ADOS look similar to that generated by studies of English-speaking cases. However, only 17% of our cases have IQs within the normal range, compared to the figure of 25% seen in most studies. This result reflects an ascertainment bias in that only severe cases of autism come to treatment in the CVCR because there are no government-sponsored support programs or early intervention programs providing an incentive to diagnose autism. The severity of mental retardation seen in most of our cases may also be exaggerated by the lack of early intervention programs and the use of IQ tests without Costa Rican norms. Still, we must formally train healthcare providers and teachers to recognize and refer autistic cases with normal or near normal IQs that are not seen in treatment.

    Background Although previous clinical study revealed that bortezomib combined with dexamethasone had improved the outcomes of relapsed or refractory multiple myeloma (RRMM), the optimal dose combinations of bortezomib and dexamethasone remain unknown. This trial aimed to observe the efficacy and safety of different dose combinations of bortezomib and dexamethasone in the treatment of RRMM patients in China.Methods A total of 168 patients with relapsed multiple myeloma (MM) who were refractory to at lest two prior treatments were enrolled in this multicenter, open-label, non-randomized, prospective clinical trial. Twenty patients received 1.3 mg/m2 of bortezomib twice weekly for 2 weeks of a 3-week cycle for up to 8 cycles and oral or intravenous dexamethasone 20 mg on the day of and after each bortezomib dose (group 1); 66 patients received less than 1.3 mg/m2(0.7-1.0 mg/m2) of bortezomib and dexamethasone 20 mg on the same schedule (group 2); 37 patients received 1.3 mg/m2 of bortezomib and dexamethasone 40 mg (group 3) and 45 patients received less than 1.3 mg/m2 (0.7-1.0 mg/m2)of bortezomib and dexamethasone 40 mg (group 4). The response was evaluated according to the criteria of the European Group for Blood and Marrow Transplantation and confirmed by an independent review committee. Adverse events were graded according to the National Cancer Institute Common Toxicity Criteria, version 3.0. Results The median age of groups 1 to 4 was 61,62, 56, and 60 years, respectively. Most patients were in stages Ⅱ/Ⅲ of MM and the most common subtype was IgG The rate of overall response to bortezomib and dexamethasone of group 1 to 4 was 72.2% (13/18), 73.8% (48/65), 78.8% (26/33) and 78.0% (32/41) (P=0.91), including a complete response rate of 22.2% (4/18), 20.0% (13/65), 33.3% (11/33) and 29.3% (12/41) (P=0.67), respectively. There was no statistical significance in time to progression and overall survival among these 4 groups (P >0.05). The most
