    The SEIS experiment is the primary payload of the Geophysical Monitoring Station (GEMS) Mission Proposal, submitted to NASA in the frame of the 2010 Discovery program, and recently selected for the phase A study. The objective of the GEMS SEIS experiment is the determination of the deep internal structure of Mars. In particular, geophysical parameters of first importance, such as the state (liquid/solid) and size of the core, as well as structure of the mantle and shape of discontinuities will be determined by the experiment. It will measure seismic activity in a very broad band of signal, from the tidal frequencies (0.05 mHz) up to the short period frequencies (50 Hz), to address the widest range of scientific questions, from the state of the inner core to the meteoritic rate measurement. Infrasound, which might be associated to dust devils and atmospheric discharge, will be also monitored. The instrument integrates a Very Broad Band (VBB) 3 axis seismometer, completed by another trihedron of MEMS short period seismometers, environmental sensors for pressure, wind and temperature, and an infrasound sensor is additionally considered. The sensors will be deployed on the Martian ground by a robotic arm from the Phoenix lander platform and protected by a wind and thermal shield. The sensor assembly, which contains all seismic sensors, the leveling system, as well as house-keeping and temperature measurements, will be deployed on the soil in order to allow the best possible mechanical coupling with the ground motion. Thanks to the wind and thermal shield, together with the sensors' specific containers (vacuum sphere for VBBs), long term VBB bias will be protected from both temperature and pressure variations (as well as passively compensated), allowing the sensor to operate in the rough Martian thermal environment. A dedicated electronics will manage the overall experiment and ultra-low noise, space qualified 24 bits A/D converters will perform the acquisition. The overall mass of the SEIS instrument is about 9.6 kg, including all sensors, data control processors and installation devices, while power consumption is not exceeding 2W. The proposed instrument has been developed up to PDR in the frame of the ExoMars Humbold payload, and further developments were achieved in the frame of the Japanese SELENE2 project. Most critical parts have been tested, including shock tests for pivots, electronics components and displacement sensors. TRL 6 is expected at the end of 2011. The GEMS phase A will end by March 2012, and the final NASA continuation decision is due in June 2012. GEMS is planned to be launched in 2016.

The instrument operation is designed to be very simple. It will operate in a deploy and forget strategy (with a deployment and closely monitored during the first month however) uploading data and events of interests at each pass of the relay satellite. When relay is not available, the data will be stored on-board. The upload of data will be made on the basis of raw compressed data, plus an excerpt of the high frequency events of the day. The proposed instrument has been developed up to PDR in the frame of the ExoMars Humbold payload. Most critical parts have been tested, including shock tests for pivot, electronics components and displacement sensors. TRL 6 is expected at the end of 2011.

    Teacher will demonstrate the SeisMac program. Shake the laptop in the three different directions, showing how the different directions are recorded on the three different components. Adjust both the vertical and horizontal scales to show how the same motions can be represented differently. Setting the vertical scales on -1 to +1, tilt the laptop 90 deg in each of the three directions to demonstrate that the seismograms are records of acceleration (accelerograms). When the laptop is oriented normally, the baseline of the vertical component is 1 g and the two horizontal components have baselines of 0 g. However, when the laptop is tilted the vertical component goes to 0 g and one of the horizontal components will go to 1 g. Teacher will present real 3-component seismograms for actual data, and discuss the major seismic phases (P, S, Love, Rayleigh), showing the components they arrive on: P is primarily on vertical, S is primarily on radial and transverse, Love is primarily on the transverse, and the Rayleigh wave is primarily on both vertical and radial components. Students will take turns shaking the seismometer to try to directly replicate the actual seismograms. If two sets of seismograms are used, the teacher can talk about the differences between seismograms at stations that are nearer or further from the seismometer.

    The SEIS experiment is the primary payload of the Interior Structure investigation using Seismology and Heat Transport (INSIGHT) Mission Proposal, submitted to NASA in the frame of the 2010 Discovery program, and selected for a competitive phase A study, together with two other projects. The objective of the INSIGHT SEIS experiment is the determination of the deep internal structure of Mars. In particular, geophysical parameters of first importance, such as the state (liquid/solid) and size of the core, structure of the mantle, shape of discontinuities, thickness of the crust will be determined by the experiment. It will measure seismic activity in a very broad band of signal, from the tidal frequencies (0.05 mHz) up to the short period frequencies (50 Hz), to address the widest range of scientific questions, from the state of the core to the meteoritic impact and quake rates. The instrument integrates a Very Broad Band (VBB) 3 axis seismometer, completed by another trihedron of MEMS short period seismometers, environmental sensors for pressure, wind and temperature, The sensors will be deployed on the Martian ground by a robotic arm from a Phoenix-type lander platform and protected by a wind and thermal shield. The sensor assembly, which contains all seismic sensors, the leveling system, as well as house-keeping and temperature measurements, will be deployed on the soil in order to allow the best possible mechanical coupling with the ground motion. The wind and thermal shield, the sensors' specific containers (vacuum sphere for VBBs) and a passive thermal compensation system will achieve a very high protection of the VBB against temperature and pressure variations, allowing the sensor to operate in the rough Martian thermal environment while reaching a deection threshold below 10-9 ms-2 Hz-1/2 in the VBB bandwidth. A dedicated electronics will manage the overall experiment and ultra-low noise, space qualified 24 bits A/D converters will perform the acquisition. The proposed instrument has been developed up to PDR in the frame of the ExoMars Humbold payload in 2009, and further developments were achieved in the frame of the Japanese SELENE2 project and the phase A of the INSIGHT project. During the INSIGHT Phase A, Tests of the Earth version of the VBB have been performed in either low noise seismic vault, in the Black Forest Observatory, or in more realistic conditions under wind and thermal shield at the Reunion Island. Most critical parts have been thoroughly tested, and the qualification models are ready to be produced in case of selection. The INSIGHT phase A has ended in March 2012, and the final NASA continuation decision is due in August 2012. If selected, INSIGHT will be launched in 2016.

    Introduction: The SEIS experiment is the primary payload of the Interior Structure Investigation using Seismology and Heat Transport (InSight) mission selected by NASA in August 2012 to be the next Mars mission. The objective of the InSight SEIS experiment is the determination of the deep internal structure of Mars. In particular, geophysical parameters of first importance, such as the state (liquid/solid) and size of the core, structure of the mantle, shape of discontinui-ties and thickness of the crust will be determined by the experiment. It will measure seismic activity over a very broad frequency band, from tidal frequencies (0.05 mHz) up to high frequencies (50 Hz), to address a wide range of scientific questions, from the state of the core to the meteoritic impact rate, marsquake rate and the response of the planet to the Phobos tide. Description of the instrument: The instrument includes notably a Very Broad Band (VBB) 3 axis seis-mometer which is developed by the ';Institut du Globe de Paris' (IPGP) under the funding of CNES. The sensor assembly, which also contains a MEMS short-period seismometer, will be deployed on the Martian ground by a robotic arm from a Phoenix-type lander platform and will be protected by a wind and thermal shield. The wind and thermal shield,together with a vacuum sphere and a passive compensation system will achieve a very high protection of the VBB against temperature and pressure variations, allowing the sensor to operate in the rough Martian thermal environment while reaching a detection threshold below 10-9 ms-2 Hz-1/2 in the VBB bandwidth. Conclusion: Performance has been demonstrated with previous prototypes and the SEIS experiment of the InSight mission will therefore provide high-quality seismic signal acquisition and associated seismic information during one martian year. The delivery of the payload is planned for the end of 2014 and the launch is in March 2016 SEIS deployed on the ground next to the lander Single-axis VBB-prototype with proximity electronics

IPGP (France) has the overall responsibility of the experiment and is responsible for the VBB and environmental sensors. ETHZ (Switzerland) is responsible for the electronics of the experiment and JPL (USA) for the SP (Short Period) sensors. SEIS instrument was first proposed and accepted for NetLander mission (and will also be in charge of data acquisition for SPICE experiment). This seismic package should also be proposed for future missions.

  18. SeisMac 2.0

    NSDL National Science Digital Library

    SeisMac is a free Mac OS X application that turns MacBook or MacBook Pro laptops into seismographs. It uses the Sudden Motion Sensor (accelerometer) that these machines are equipped with to create and display real-time, three-axis acceleration graphs (seismograms). The resizable, real-time scrolling display lets students see the seismic waves from tapping their toes on the floor, lay the laptop on their chests to see their heartbeats, or see seismic waves from real earthquakes. The software allows users to pause the display to study an event; scroll back in time to see older data; enlarge or contract the graph, both vertically and horizontally; and copy, print or save the screen. Time labels tell exactly when an event occurred, the sampling rate can be adjusted, and acceleration data can be smoothed. The site features a link to download the software and a link to help files for installing and using it.

    2011-01-01

    Fistula-in-ano is the most common form of perineal sepsis. Typically, a fistula includes an internal opening, a track, and an external opening. The external opening might acutely appear following infection and/or an abscess, or more insiduously in a chronic manner. Management includes control of infection, assessment of the fistulous track in relation to the anal sphincter muscle, and finally, definitive treatment of the fistula. Fistulotomy was the most commonly used mode of management, but concerns about post-fistulotomy incontinence prompted the use of sphincter preserving techniques such as advancement flaps, fibrin glue, collagen fistula plug, ligation of the intersphincteric fistula track, and stem cells. Many descriptive and comparative studies have evaluated these different techniques with variable outcomes. The lack of consistent results, level I evidence, or long-term follow-up, as well as the heterogeneity of fistula pathology has prevented a definitive treatment algorithm. This article will review the most commonly available modalities and techniques for managing idiopathic fistula-in-ano. PMID:21876614

    Ano1 is a recently discovered Ca2+-activated Cl? channel expressed on interstitial cells of Cajal (ICC) that has been implicated in slow-wave activity in the gut. However, Ano1 is expressed on all classes of ICC, even those that do not contribute to generation of the slow wave, suggesting that Ano1 may have an alternate function in these cells. Ano1 is also highly expressed in gastrointestinal stromal tumors. Mice lacking Ano1 had fewer proliferating ICC in whole mount preparations and in culture, raising the possibility that Ano1 is involved in proliferation. Cl? channel blockers decreased proliferation in cells expressing Ano1, including primary cultures of ICC and in the pancreatic cancer-derived cell line, CFPAC-1. Cl? channel blockers had a reduced effect on Ano1(?/?) cultures, confirming that the blockers are acting on Ano1. Ki67 immunoreactivity, 5-ethynyl-2?-deoxyuridine incorporation, and cell-cycle analysis of cells grown in low-Cl? media showed fewer proliferating cells than in cultures grown in regular medium. We confirmed that mice lacking Ano1 had less phosphorylated retinoblastoma protein compared with controls. These data led us to conclude that Ano1 regulates proliferation at the G1/S transition of the cell cycle and may play a role in tumorigenesis. PMID:21940901

    1996-08-01

    To support the signal processing and data visualization needs of CTBT related projects at SNL, a MATLAB based GUI was developed. This program is known as MatSeis. MatSeis was developed quickly using the available MATLAB functionality. It provides a time-distance profile plot integrating origin, waveform, travel-time, and arrival data. Graphical plot controls, data manipulation, and signal processing functions provide a user friendly seismic analysis package. In addition, the full power of MATLAB (the premier tool for general numeric processing and visualization) is available for prototyping new functions by end users. This package is being made available to the seismic community in the hope that it will aid CTBT research and will facilitate cooperative signal processing development. 2 refs., 5 figs.

    This guide is intended to enable researchers working with seismic data, but lacking backgrounds in computer science and programming, to develop seismic algorithms using the MATLAB-based MatSeis software. Specifically, it presents a series of step-by-step instructions to write four specific functions of increasing complexity, while simultaneously explaining the notation, syntax, and general program design of the functions being written. The ultimate goal is that that the user can use this guide as a jumping off point from which he or she can write new functions that are compatible with and expand the capabilities of the current MatSeis software that has been developed as part of the Ground-based Nuclear Explosion Monitoring Research and Engineering (GNEMRE) program at Sandia National Laboratories.

    2014-08-01

    In the last decade, many studies applied surface analysis techniques (SEM, XPS and SIMS) to understand the formation of SEI layers on Li-ion battery electrodes. This work was meant as a comparative model study of the SEI layer formation, which combined in situ SEM imaging with TOF SIMS depth profiling of four samples of the same graphite electrode material, which was subjected to different charge-discharge cycling schemes in a Li-ion battery. Besides comparing compositions of sub-surface regions of these differently processed electrodes, we wanted to know whether these compositions depend on after-cycling sample preparation, in particular if a brief exposure of these samples to air would affect the compositions measured by TOF SIMS. We found that the exposure to air (1) increases secondary ion yield for all species, and (2) changes shapes of SIMS depth profiles for some key species. For selected samples, we also conducted a comparison between the conventional single beam TOF-SIMS depth profiling and a high resolution dual beam depth profiling and found that the former approach can detect the same features in depth profiles as the latter one. We interpreted this as an indication that the sample surface morphology (high roughness) could be a limiting factor in this SEI study, suggesting that specially designed model samples with smooth surfaces are a better choice for future studies.

  16. Communications system evolutionary scenarios for Martian SEI support

    In the Space Exploration Initiative (SEI) mission scenarios, expanding human presence is the primary driver for high data rate Mars-Earth communications. To support an expanding human presence, the data rate requirement will be gradual, following the phased implementation over time of the evolving SEI mission. Similarly, the growth and evolution of the space communications infrastructure to serve this requirement will also be gradual to efficiently exploit the useful life of the installed communications infrastructure and to ensure backward compatibility with long-term users. In work conducted over the past year, a number of alternatives for supporting high data rate Mars-Earth communications have been analyzed with respect to their compatibility with gradual evolution of the space communications infrastructure. The alternatives include RF, millimeter wave (MMW), and optical implementations, and incorporate both surface and space-based relay terminals in the Mars and Earth regions. Each alternative is evaluated with respect to its ability to efficiently meet a projected growth in data rate over time, its technology readiness, and its capability to satisfy the key conditions and constraints imposed by evolutionary transition. As a result of this analysis, a set of attractive alternative communications architectures have been identified and described, and a road map is developed that illustrates the most rational and beneficial evolutionary paths for the communications infrastructure.

    Nuclear Thermal Propulsion (NTP) has been identified as a critical technology in support of the NASA Space Exploration Initiative (SEI). In order to safely develop a reliable, reusable, long-lived flight engine, facilities are required that will support ground tests to qualify the nuclear rocket engine design. Initial nuclear fuel element testing will need to be performed in a facility that supports a realistic thermal and neutronic environment in which the fuel elements will operate at a fraction of the power of a flight weight reactor/engine. Ground testing of nuclear rocket engines is not new. New restrictions mandated by the National Environmental Protection Act of 1970, however, now require major changes to be made in the manner in which reactor engines are now tested. These new restrictions now preclude the types of nuclear rocket engine tests that were performed in the past from being done today. A major attribute of a safely operating ground test facility is its ability to prevent fission products from being released in appreciable amounts to the environment. Details of the intricacies and complications involved with the design of a fuel element ground test facility are presented in this report with a strong emphasis on safety and economy.

  19. Mineralogical aspects of Morro de Seis Lagos deposit (Amazonas, Brazil).

    2014-05-01

    The alkaline body Morro dos Seis Lagos, situated in the northwest Amazonian region, is a Nb bearing deposit formed by thick lateritic regolith as circular geological feature about 5 km in diameter. The host rock of this deposit is an intensely weathered siderite carbonatite. The alkaline intrusion body was formed during the late Mesozoic and enriched during the Cenozoic by process of denudation of the surrounding rocks and formation of lateritic cover with thickness in the order of hundreds of meters. In this process, enrichment of Nb, Fe, Ti, Mn, P and rare earth elements (REE) occurred where the lateritic regolith represents the major Nb mineralization, with estimated inferred reserves of 2.9 billion ton@ 2.8 % Nb2O5, one of the largest deposits of Nb in the world. The mineralogical composition of the lateritic regolith has the predominance of the goethite and hematite, followed by oxy - hydroxides of Mn, Ti - Nb oxides, pyrochlore, cerianite and phosphates. The lateritic regolith samples showed high contents of Fe2O3 < 89.0%, TiO2 (< 12.54 %) and MnO2 (< 9.90 %). The goethite minerals show several generations that are related to different environmental conditions with dissolution and precipitation process, which indicate intense movement of the solutions with Fe in the aqueous medium. The main Nb minerals are ilmenorutile, rutile and brookite where the ilmenorutile can have content up to 20 % Nb2O5. The P-rich minerals, like monazite and its alteration products, is the main REE phases. These minerals have high concentration of Ce2O3, La2O3 and Nb2O3, where ?REE > 40 %, and is followed by elevated Th concentration, which locally has concentration higher than (18%). Another REE mineral is the cerianite. The main manganese minerals are hollandite, romanechite (BaMn9O16[OH4] - mixtures of manganese oxides) and amorphous Mn oxy - hydroxides. The higher concentration of MnO2 (about 40 %) is restricted to manganesiferous range, where manganese minerals occur as layers and filling voids, indicating strong remobilization by later process.

    Simultaneous sightings and acoustic detections of sei whales (Balaenoptera borealis) are scarce, and there are few published data describing their vocalizations. Analysis of recordings from directional frequency analysis and recording sonobuoys in the presence of sei whales in the Southern Ocean in March 2013 identified both downsweep and upsweep calls. Sound frequencies within all calls were between 34 and 87?Hz with an average call duration of 1.1?s. These very low-frequency sounds share characteristics with sei whale calls recorded near the Hawaiian Islands and off Cape Cod in winter and summer, respectively, but are the first documented sei whale calls in the Southern Ocean that are clearly less than 100?Hz.

    Diabetes affects many organs including the stomach. Altered number and function of interstitial cells of Cajal (ICC), the gastrointestinal pacemaker cells, underlie a number of gastrointestinal motility disorders, including diabetic gastroparesis. In the muscle layers, ICC selectively express Ano1, thought to underlie classical Ca2+-activated Cl? currents. Mice homozygous for Ano1 knock-out exhibit abnormal ICC function and motility. Several transcripts for Ano1 are generated by alternative splicing of four exons. Here, we report expression levels of transcripts encoded by alternative splicing of Ano1 gene in gastric muscles of patients with diabetic gastroparesis and nondiabetic control tissues. Expression of mRNA from two alternatively transcribed exons are significantly different between patients and controls. Furthermore, patients with diabetic gastroparesis express mRNA for a previously unknown variant of Ano1. The 5? end of this novel variant lacks exons 1 and 2 and part of exon 3. Expression of this variant in HEK cells produces a decreased density of Ca2+-activated Cl? currents that exhibit slower kinetics compared with the full-length Ano1. These results identify important changes in expression and splicing of Ano1 in patients with diabetic gastroparesis that alter the electrophysiological properties of the channel. Changes in Ano1 expression in ICC may directly contribute to diabetic gastroparesis. PMID:21349842

  6. ANO1 (TMEM16A) in pancreatic ductal adenocarcinoma (PDAC).

    2014-08-28

    Pancreatic ductal adenocarcinoma (PDAC) has one of the worst survival rates of all cancers. ANO1 (TMEM16A) is a recently identified Ca(2+)-activated Cl(-) channel (CaCC) that is upregulated in several tumors. Although ANO1 was subject to extensive studies in the recent years, its pathophysiological function has only been poorly understood. The aim of the present study is to establish the significance of ANO1 in PDAC behavior and demarcate its roles in PDAC from those of the volume-regulated anion channel (VRAC). We performed qPCR and Western blot measurements on different PDAC cell lines (Panc-1, Mia PaCa 2, Capan-1, AsPC-1, BxPC-3) and compared the results to those obtained in a human pancreatic ductal epithelium (HPDE) cell line. All cancer cell lines showed an upregulation of ANO1 on mRNA and protein levels. Whole-cell patch-clamp recordings identified large Ca(2+) and voltage-dependent Cl(-) currents in PDAC cells. Using siRNA knockdown of ANO1 and three ANO1 inhibitors (T16Ainh-A01, CaCCinh-A01, and NS3728), we found that ANO1 is the main constituent of CaCC current in PDAC cells. We further characterized these three inhibitors and found that they had unspecific effects on the free intracellular calcium concentration. Functional studies on PDAC behavior showed that surprisingly inhibition of ANO1 did not influence cellular proliferation. On the other hand, we found ANO1 channel to be pivotal in PDAC cell migration as assessed in wound healing experiments. PMID:25163766

    Immune cells and platelets maintain plasma membrane phospholipid asymmetry. Upon activation, this asymmetry is disrupted by phospholipid scrambling (PS), which is a major step during activation of immune cells, hemostasis and apoptosis. Anoctamin 6 (Ano6; TMEM16F) causes chloride (Cl?) and cation currents and is required for Ca2+-dependent PS. It is defective in blood cells from patients with Scott syndrome, a rare bleeding disorder. We examined if Cl? currents and PS are related, whether both processes are Ca2+ dependent, and whether Ca2+-independent scrambling during intrinsic and extrinsic apoptosis is controlled by Ano6. Ca2+ increase by ionomycin activated Ano6 Cl? currents and PS in normal lymphocytes, but not in B-lymphocytes from two different patients with Scott syndrome. Fas ligand (FasL) did not increase intracellular Ca2+, but activated Cl? currents in normal but not in Scott lymphocytes. Whole-cell currents were inhibited by Cl? channel blockers and by siRNA knockdown of Ano6. In contrast, intrinsic mitochondrial apoptosis by ABT-737 did not induce Cl? currents in lymphocytes. PS was not inhibited by blockers of Ano6 or removal of Cl? ions. Remarkably, Ca2+-independent scrambling due to extrinsic (FasL) or intrinsic (ABT-737) apoptosis was unchanged in Scott cells. We conclude that: (i) Ano6 Cl? currents are activated by increase in cytosolic Ca2+, or Ca2+ independent by stimulation of Fas receptors; (ii) Ca2+-dependent PS induced by Ano6 does not require Cl? currents; (iii) Ca2+-independent PS does not require Ano6; (iv) Ano6 is necessary for Ca2+-dependent PS, but not by increasing intracellular Ca2+.

  9. Theory of SEI Formation in Rechargeable Batteries: Capacity Fade, Accelerated Aging and Lifetime Prediction

    E-print Network

    Pinson, Matthew B

    2012-01-01

    Cycle life is critically important in applications of rechargeable batteries, but lifetime prediction is mostly based on empirical trends, rather than mathematical models. In practical lithium-ion batteries, capacity fade occurs over thousands of cycles, limited by slow electrochemical processes, such as the formation of a solid-electrolyte interphase (SEI) in the negative electrode, which compete with reversible lithium intercalation. Focusing on SEI growth as the canonical degradation mechanism, we show that a simple single-particle model can accurately explain experimentally observed capacity fade in commercial cells with graphite anodes, and predict future fade based on limited accelerated aging data for short times and elevated temperatures. The theory is extended to porous electrodes, predicting that SEI growth is essentially homogeneous throughout the electrode, even at high rates. The lifetime distribution for a sample of batteries is found to be consistent with Gaussian statistics, as predicted by th...

The chemistry and morphology of the solid electrolyte interphase (SEI) film and its correlation with the electrode performance are studied. The addition of fluoroethylene carbonate (FEC) in electrolyte significantly reduces electrolyte decomposition and creates a very thin and uniform SEI layer on the cycled electrode surface which could promote the kinetics of Na-ion migration/transportation, leading to excellent electrochemical performance.

    An evolutionary program of space science missions for the lunar surface and the transportation system concept developed to deploy them are described. Lunar-based science systems will evolve from simple, robotic instruments such as a lunar transit telescope (LTT) to large, observatory-class instruments like a 16-meter optical telescope assembled by astronauts at a lunar base. A transportation system concept to support the Space Exploration Initiative (SEI) and the deployment of these science payloads is described. Beginning with a post-Artemis lander capability, a modular approach to lunar landers is proposed as a way to maximize commonality and to support evolving SEI transportation requirements.

    Blood clotting and fibrinolytic systems were studied in the plasma of a sei whale (Balaenoptera borealis). The sei whale belongs to the suborder baleen whales of the order Cetacea. Whale plasma had a greatly prolonged kaolin-activated partial thromboplastin time and was deficient in Hageman factor (factor XII), Fletcher factor (a plasma prekallikrein), and PTA (factor XI). All other clotting factor activities were present in amounts comparable to that of normal human plasma. Whale plasminogen was activated by human urokinase, but not by streptokinase. Whale plasma contained inhibitory activities against thrombin, activated Stuart factor, activated PTA, activated Fletcher factor, and plasmin. PMID:967876

The technologies were those believed most appropriate to the SEI missions, and included solar, electrochemical, and isotope systems. The candidates were characterized with respect to system mass, deployed area, and volume. For each of the missions a preliminary selection was made. Results of this study depict the available power sources in light of mission requirements as they are currently defined.

    2010-01-01

    Sexual abuse is a problem of epidemic proportions in the United States. Pediatric nurse practitioners (PNPs) are at the forefront of providing care to children and families. The PNP is in a unique position to educate patients and families regarding sexual abuse and dispel common myths associated with sexual abuse. One such myth is that a normal ano-genital examination is synonymous with the absence of sexual abuse. This article will provide primary care providers, including PNPs, with a framework for understanding why a normal ano-genital examination does not negate the possibility of sexual abuse/assault. Normal ano-genital anatomy, changes that occur with puberty, and physical properties related to the genitalia and anus will be discussed. Photos will provide visualization of both normal variants of the pre-pubertal hymen and genitalia as well as changes that occur with puberty. Implications for practice for PNPs will be discussed.

    The use of the Space Station Freedom (SSF) for life sciences research is evaluated from the standpoint of requirements for the Space Exploration Initiative (SEI). SEI life sciences research encompasses: (1) biological growth and development in space; (2) life support and environmental health; (3) physiological/psychological factors of extended space travel; and (4) space environmental factors. The platforms required to support useful study in these areas are listed and include ground-based facilities, permanently manned spacecraft, and the Space Shuttle. The SSF is shown to be particularly applicable to the areas of research because its facilities can permit the study of gravitational biology, life-support systems, and crew health. The SSF can serve as an experimental vehicle to derive the required knowledge needed to establish a commitment to manned Mars missions and colonization plans.

    2012-12-01

    SeisCode is a community repository for software used in seismological and related fields. The repository is intended to increase discoverability of such software and to provide a long-term home for software projects. Other places exist where seismological software may be found, but none meet the requirements necessary for an always current, easy to search, well documented, and citable resource for projects. Organizations such as IRIS, ORFEUS, and the USGS have websites with lists of available or contributed seismological software. Since the authors themselves do often not maintain these lists, the documentation often consists of a sentence or paragraph, and the available software may be outdated. Repositories such as GoogleCode and SourceForge, which are directly maintained by the authors, provide version control and issue tracking but do not provide a unified way of locating geophysical software scattered in and among countless unrelated projects. Additionally, projects are hosted at language-specific sites such as Mathworks and PyPI, in FTP directories, and in websites strewn across the Web. Search engines are only partially effective discovery tools, as the desired software is often hidden deep within the results. SeisCode provides software authors a place to present their software, codes, scripts, tutorials, and examples to the seismological community. Authors can choose their own level of involvement. At one end of the spectrum, the author might simply create a web page that points to an existing site. At the other extreme, an author may choose to leverage the many tools provided by SeisCode, such as a source code management tool with integrated issue tracking, forums, news feeds, downloads, wikis, and more. For software development projects with multiple authors, SeisCode can also be used as a central site for collaboration. SeisCode provides the community with an easy way to discover software, while providing authors a way to build a community around their software packages. IRIS invites the seismological community to browse and to submit projects to https://seiscode.iris.washington.edu/

  8. Extension to High Frequencies of the Experiment Capability of SEIS-UK

    NASA Astrophysics Data System (ADS)

    Brisbourne, A.; Horleston, A.; Denton, P.

    2004-12-01

    The seismic equipment facility serving the UK academic community, SEIS-UK, has recently purchased 15 high frequency seismic recording systems capable of sampling at up to 24kHz. A suite of 3 component 30Hz geophones and piezoelectric accelerometers has also been acquired. The SAQS systems, designed and built by ISS International of South Africa, represent a significant extension in the capability of the SEIS-UK facility. The units record 24bit data from 6 channels, at sample rates of 50Hz to 24kHz, in continuous or triggered mode. An external GPS antenna and removable hard disk allow the systems to run autonomously. The 6 channels can be configured as any combination of tri-, bi- or uni-axial systems. The recording systems are also compatible with broadband seismometers. Although originally designed for the purpose of hardrock mine monitoring, the SAQS system is a good solution for a range of high frequency seismic monitoring experiments, especially controlled source or high-resolution surveys. The SEIS-UK systems have been modified with disk-heaters to extend the environmental operating capability. The addition of an external GPS antenna means the units can be used in the same way as any other passive seismic field system. However, the functionality of the recorder is significantly greater than that of many standard seismic systems. The equipment is currently loaned to the British Antarctic Survey for use as part of a large multi-disciplinary experiment on the Rutford Ice Stream in Antarctica. The instruments will be deployed in an array centred on the main sub-glacial access hole. Instruments will detect events from the bed of the glacier with the aim of investigating the ice flow mechanisms and for determining the relationship between the ice sheet, sub-glacial bed and tidal motion.

  12. The Installation of Satellite Modems on SEIS-UK Supported Remote Seismic Deployments

    2006-12-01

    SEIS-UK, as the UK's NERC funded national seismic equipment facility, is frequently involved in large, often remote, temporary seismic networks (running for up to 2 years). Up till now all these deployments have been managed solely by on-site maintenance but now SEIS-UK is investing in a number of satellite modems. The Michrosat 2400 OEM Modems, provided by Wireless Innovations Ltd, will be integrated within Guralp DCM data-logger units and will be used to provide regular state-of-health reports from remote networks. They will also provide the user the facility to communicate with the deployed systems, apply configuration changes and request system re-boots. This should lead to less instrument down-time and allow for more focussed site visits and thus, hopefully, reduce the cost (and servicing time) of remote installations. The Michrosat Modems are relatively low-powered and draw a maximum current of 2.5A (at 4.4v) for a few microseconds when initialising a call, dropping to bursts of approximately 1A when transmitting. This makes them ideally suited to temporary deployments relying on solar charged battery power. We will present examples of the configuration and typical deployment of the modems and the types of data transmitted.

  13. Electrochemical in situ investigations of SEI and dendrite formation on the lithium metal anode.

    2015-04-14

    This comparative work studies the self-enforcing heterogeneity of lithium deposition and dissolution as the cause for dendrite formation on the lithium metal anode in various liquid organic solvent based electrolytes. In addition, the ongoing lithium corrosion, its rate and thus the passivating quality of the SEI are investigated in self-discharge measurements. The behavior of the lithium anode is characterized in two carbonate-based standard electrolytes, 1 M LiPF6 in EC/DEC (3?:?7) and 1 M LiPF6 in EC/DMC (1?:?1), and in two alternative electrolytes 1 M LiPF6 in TEGDME and 1 M LiTFSI in DMSO, which have been proposed in the literature as promising electrolytes for lithium metal batteries, more specifically for lithium/air batteries. As a result, electrolyte decomposition, SEI and dendrite formation at the lithium electrode as well as their mutual influences are understood in the development of overpotentials, surface resistances and lithium electrode surface morphologies in subsequent lithium deposition and dissolution processes. A general model of different stages of these processes could be elaborated. PMID:25735488

    Vitamin C is considered as an important anticancer therapeutic agent although this view is debatable. In this study, we introduce a physiological mechanism demonstrating how vitamin C exerts anticancer activity that induces cell cycle arrest and apoptosis. Our previous and current data reveal that p53 tumor suppressor is the prerequisite factor for stronger anticancer effects of vitamin C. In addition, vitamin C-mediated cancer cell cytotoxicity appears to be achieved at least partly through the downregulation of the p34SEI-1 oncoprotein. Our previous study showed that p34SEI-1 increases the survival of various types of cancer cells by inhibiting their apoptosis. Present data suggest that vitamin C treatment decreases the p34SEI-1 expression at the protein level and therefore alleviates its anti-apoptotic activity. Of note, SIAH1, E3 ubiquitin ligase, appears to be responsible for the p34SEI-1 polyubiquitination and its subsequent degradation, which is dependent on p53. In summary, vitamin C increases cancer cell death by inducing SIAH1-mediated polyubiquitination/degradation of the p34SEI-1 oncoprotein in a p53-dependent manner. PMID:25586269

    An Interagency Nuclear Safety Policy Working Group (NSPWG) was chartered to recommend nuclear safety policy, requirements, and guidelines for the Space Exploration Initiative (SEI) nuclear propulsion program to facilitate the implementation of mission planning and conceptual design studies. The NSPWG developed a top- level policy to provide the guiding principles for the development and implementation of the nuclear propulsion safety program and the development of Safety Functional Requirements. In addition the NSPWG reviewed safety issues for nuclear propulsion and recommended top-level safety requirements and guidelines to address these issues. Safety requirements were developed for reactor start-up, inadvertent criticality, radiological release and exposure, disposal, entry, and safeguards. Guidelines were recommended for risk/reliability, operational safety, flight trajectory and mission abort, space debris and meteoroids, and ground test safety. In this paper the specific requirements and guidelines will be discussed.

    This paper defines the types of technology that would be used in a lunar base for environmental control and life support system and how it might relate to in situ materials utilization (ISMU) for the Space Exploration Initiative (SEI). There are three types of interaction between ISMU and the Environmental Control and Life Support System (ECLSS): (1) ISMU can reduce cost of water, oxygen, and possibly diluent gasses provided to ECLSS--a corollary to this fact is that the availability of indigenous resources can dramatically alter life support technology trade studies; (2) ISMU can use ECLSS waste systems as a source of reductant carbon and hydrogen; and (3) ECLSS and ISMU, as two chemical processing technologies used in spacecraft, can share technology, thereby increasing the impact of technology investments in either area.

    Public comments are sought on this final SEIS, which supplements the 1992 Columbia River Salmon Flow Measures Options Analysis (OA)/Environmental Impact Statement (EIS). The Corps of Engineers, in cooperation with the Bonneville Power Administration and the Bureau of Reclamation proposes five alternatives to improve flows of water in the lower Columbia-Snake rivers in 1993 and future years to assist the migration of juvenile and adult anadromous fish past eight hydropower dams. These are: (1) Without Project (no action) Alternative, (2) the 1992 Operation, (3) the 1992 Operation with Libby/Hungry Horse Sensitivity, (4) a Modified 1992 Operation with Improvements to Salmon Flows from Dworshak, and (5) a Modified 1992 Operation with Upper Snake Sensitivity. Alternative 4, Modified 1992 Operations, has been identified as the preferred alternative.

    This work reports a method to explore the catalytic reactivity of electrode surfaces towards the decomposition of carbonate solvents [ethylene carbonate (EC), dimethyl carbonate (DMC), and EC/DMC]. We show that the decomposition of a 1:1 wt% EC/DMC mixture is accelerated over certain commercially available LiCoO2 materials resulting in the formation of CO2 while over pure EC or DMC the reaction is much slower or negligible. The solubility of the produced CO2 in carbonate solvents is high (0.025 grams/mL) which masks the effect of electrolyte decomposition during storage or use. The origin of this decomposition is not clear but it is expected to be present on other cathode materials and may affect the analysis of SEI products as well as the safety of Li-ion batteries.

    INTRODUCTION Fistulas are a relatively common occurrence in Crohn's disease (CD), and often present early in the disease process. Additionally, patients suffering from either CD or ulcerative colitis are shown to have an increased risk of colorectal malignancies compared with the general population. PRESENTATION OF CASE We present a case of adenocarcinoma in an ano-vaginal fistula in a patient with longstanding CD. DISCUSSION Various pathogenic mechanisms for the development of carcinoma in fistulas have been suggested, but there is no consensus and indeed this risk may be cumulative. In this case report, we also discuss the pathogenesis of mucinous adenocarcinoma in fistulas secondary to CD. CONCLUSION Better detection of adenocarcinoma in patients presenting with persistent non-resolving fistulas in the presence of CD should be undertaken with regular biopsies following examinations under anaesthetic of the anorectum.

    The extra compositional freedom available in ternary compounds allow flexibility to tune their electronic and structural properties compared to the binary counterparts. Indeed, the Tl-based ternary semiconductor Tl6SeI4 is a promising candidate for radiation detectors. It has a band gap (1.86 eV) that is intermediate between those of Tl2Se (0.6 eV) and TlI (2.75 eV) and suitable for room temperature detectors. However, the flexibility in ternary semiconductors may come at the expense of more channels for defect formation and more complex defect chemistry, which need to be studied in details. To better understand the properties of Tl6SeI4in relation to the radiation detection, we performed first-principles study of electronic structure, phase diagram, and dielectric, optical, and defect properties in Tl6SeI4.[1] We will discuss the properties of defects and their diffusion barriers in the context of resistivity and polarization phenomenon in Tl6SeI4.

    Li-S battery is a complicated system with many challenges existing before its final market penetration. While most of the reported work for Li-S batteries is focused on the cathode design, we demonstrate in this work that the anode consumption accelerated by corrosive polysulfide solution also critically determines the Li-S cell performance. To validate this hypothesis, ionic liquid (IL) N-methyl-N-butylpyrrolidinium bis(trifluoromethylsulfonyl)imide (Py14TFSI) has been employed to modify the properties of SEI layer formed on Li metal surface in Li-S batteries. It is found that the IL-enhanced passivation film on the lithium anode surface exhibits much different morphology and chemical compositions, effectively protecting lithium metal from continuous attack by soluble polysulfides. Therefore, both cell impedance and the irreversible consumption of polysulfides on lithium metal are reduced. As a result, the Coulombic efficiency and the cycling stability of Li-S batteries have been greatly improved. After 120 cycles, Li-S battery cycled in the electrolyte containing IL demonstrates a high capacity retention of 94.3% at 0.1 C rate. These results unveil another important failure mechanism for Li-S batteries and shin the light on the new approaches to improve Li-S battery performances.

    Sexual assault continues to represent the most rapidly growing violent crime in the USA. Statistics prove a persistent rise in rape incidence with poor conviction rates. This knowledge, along with the vast multitude of emotional sequilae of rape and self-perceived inferior legal status of the involved females results in a high percentage of unreported cases. This presented paper reports of ano-genital trauma in case of sexual assault. Under 2970 victims of sexual assault, examined and treated between 1967-1985 in the Department of Gynecology and Obstetrics Charlottenburg (Free University of Berlin), a percentage of almost 40% was represented by children in the age of 0-14. Therefore, only 1696 patients with complete gynecological examination with correct case history examination for injuries and traces of sperm, infections could be presented. The total rate of injuries was: Perineum 8.4%, vulva 5.4%, vagina 1.8%, pelvis/thighs 14.2%. The highest risk to be injured in case of sexual assault had the age group of victims over 55 years (nearly 50%). The lowest rate of injury has been encountered in the age groups 0-5 years, 6-10 years, 26-35 years: Under 10%. A solitary anal-injury has not been found. Specific training in emergent and chronic care for the victims, both physical and mental, in conjunction with preventive measures to genital infections and pregnancy, are necessary when the gynecologist is involved.

    In 2016, the SEIS experiment, part of the INSIGHT mission of NASA's Discovery program to Mars, is expected to provide the very first seismic records on this planet. This experiment consists in a single station that will record both short-period and broad-band data. The challenge of obtaining information on the location of seismic sources and on the deep seismic structure of the planet using a single station is tested against Earth analogues recorded at the German Black Forest Observatory (BFO), where the signal to noise ratios of the records are close to the values expected for the SEIS experiment on Mars. Estimates of tectonic activity from mapped fault features and thermal modeling suggest that, in addition to smaller events, it is reasonable to anticipate recording a few events with equivalent Earth moment magnitudes in the range 4.5 - 5, or even larger, within one Martian year (i.e. two Earth years). Taking into account the smaller planetary radius of Mars relative to the Earth and lower anticipated seismic noise, due primarily to the absence of oceans, this may allow for recording of multiple orbit surface waves. Considering geometrical scaling between Mars and the Earth, we take a dataset of Earth events with moment magnitudes between 6 and 6.5, which are just above the threshold for detectability of 3rd orbit fundamental mode Rayleigh waves (R3) on quiet stations, and explore the use of several single station techniques for the estimation of source location (distance and back-azimuth from the station) and interior structure. By using the group arrival times of the first three orbits of the fundamental mode surface waves of these events, we are able to estimate the origin time and epicentral distance of the events within the accuracy of the shortest period used in the analysis (here 40 s). The precision on the estimate of the epicentral distance is about one degree, i.e. approximately 55 km on Mars, while the origin time is estimated with an accuracy of approximately 20 seconds. Although these errors are large with respect to the much smaller errors in source location using standard network data on the Earth with some systematic biases due to unmodeled 3D structure, body wave picks on relatively small datasets of 8 or 9 events allow for inversion for reasonable models of mantle velocity structure within 250 m/s in S velocity and 500 m/s in P velocity, even with very limited a priori knowledge of expected seismic structure. The Bayesian inversion of the energy diagrams of multiple orbits surface waves in the 40 s - 200 s period range, further constrain the shear velocity structure of the 250 km uppermost mantle of the Earth, i.e. down to about 400 km within Mars. Single station techniques such as this will greatly increase our constraints on the interior structure of Mars when data becomes available in 2016.

    Ca2+-activated Cl? channels (CaCCs) participate in numerous physiological functions such as neuronal excitability, sensory transduction, and transepithelial fluid transport. Recently, it was shown that heterologously expressed anoctamins ANO1 and ANO2 generate currents that resemble native CaCCs. The anoctamin family (also called Tmem16) consists of 10 members, but it is not known whether all members of the family are CaCCs. Expression of ANOs 37 in HEK293 cells did not generate Cl? currents activated by intracellular Ca2+, as determined by whole cell patch clamp electrophysiology. With the use of confocal imaging, only ANO1 and ANO2 traffic to the plasma membrane when expressed heterologously. Furthermore, endogenously expressed ANO7 in the human prostate is predominantly intracellular. We took a chimeric approach to identify regions critical for channel trafficking and function. However, none of the chimeras of ANO1 and ANO5/7 that we made trafficked to the plasma membrane. Our results suggest that intracellular anoctamins may be endoplasmic reticulum proteins, although it remains unknown whether these family members are CaCCs. Determining the role of anoctamin family members in ion transport will be critical to understanding their functions in physiology and disease. PMID:22075693

    For vertebrate olfactory signal transduction, a calcium-activated chloride conductance serves as a major amplification step. However, the molecular identity of the olfactory calcium-activated chloride channel (CaCC) is unknown. Here we report a proteomic screen for cilial membrane proteins of mouse olfactory sensory neurons (OSNs) that identified all the known olfactory transduction components as well as Anoctamin 2 (ANO2). Ano2 transcripts were expressed specifically in OSNs in the olfactory epithelium, and ANO2::EGFP fusion protein localized to the OSN cilia when expressed in vivo using an adenoviral vector. Patch-clamp analysis revealed that ANO2, when expressed in HEK-293 cells, forms a CaCC and exhibits channel properties closely resembling the native olfactory CaCC. Considering these findings together, we propose that ANO2 constitutes the olfactory calcium-activated chloride channel. PMID:19561302

    The theoretical UV P Cygni profiles of the UV resonance lines for C IV, N V, Si IV, C III, and N IV of 26 O-type stars and one B star were calculated using the SEI method described by Lamers et al. (1987), taking into account the effects of turbulence in the wind, limb darkening, photospheric lines, and interstellar Ly alpha. The results were compared with profiles observed with the IUE satellite. The profile fits were found to be very accurate, showing significant improvement over previously obtained fits with the Sobolev (1958) method. The SEI method and the line fitting analysis are described and the results are presented in terms of the column densities and distributions of absorbing atoms, and the velocity laws.

  15. Automated infrasound signal detection algorithms implemented in MatSeis - Infra Tool.

    SciTech Connect

    Hart, Darren

    2004-07-01

    MatSeis's infrasound analysis tool, Infra Tool, uses frequency slowness processing to deconstruct the array data into three outputs per processing step: correlation, azimuth and slowness. Until now, an experienced analyst trained to recognize a pattern observed in outputs from signal processing manually accomplished infrasound signal detection. Our goal was to automate the process of infrasound signal detection. The critical aspect of infrasound signal detection is to identify consecutive processing steps where the azimuth is constant (flat) while the time-lag correlation of the windowed waveform is above background value. These two statements describe the arrival of a correlated set of wavefronts at an array. The Hough Transform and Inverse Slope methods are used to determine the representative slope for a specified number of azimuth data points. The representative slope is then used in conjunction with associated correlation value and azimuth data variance to determine if and when an infrasound signal was detected. A format for an infrasound signal detection output file is also proposed. The detection output file will list the processed array element names, followed by detection characteristics for each method. Each detection is supplied with a listing of frequency slowness processing characteristics: human time (YYYY/MM/DD HH:MM:SS.SSS), epochal time, correlation, fstat, azimuth (deg) and trace velocity (km/s). As an example, a ground truth event was processed using the four-element DLIAR infrasound array located in New Mexico. The event is known as the Watusi chemical explosion, which occurred on 2002/09/28 at 21:25:17 with an explosive yield of 38,000 lb TNT equivalent. Knowing the source and array location, the array-to-event distance was computed to be approximately 890 km. This test determined the station-to-event azimuth (281.8 and 282.1 degrees) to within 1.6 and 1.4 degrees for the Inverse Slope and Hough Transform detection algorithms, respectively, and the detection window closely correlated to the theoretical stratospheric arrival time. Further testing will be required for tuning of detection threshold parameters for different types of infrasound events.

    The subarctic-subtropical transition area of the western North Pacific is an important summer feeding grounds of sei whales. The oceanographic structure and circulation of this area are largely determined by strong oceanic fronts and associated geostrophic currents, namely the Polar Front (PF), Subarctic Front (SAF) and Kuroshio Extension Front (KEF). The relationship between the distribution of sei whales and oceanographic fronts was investigated using a generalized additive model (GAM), and the cetacean sighting survey data and oceanographic observations in July from 2000 to 2007 were used in the analysis. The number of individual sei whales was used as the response variable while the distances from the PF, SAF, and KEF to the whales were used as explanatory variables along with the longitude values. Sei whales were concentrated north and south of the SAF and the areas from 250 to 300 km north and from 100 to 200 km south of the SAF were estimated as high-density areas of sei whales. The entire inter-frontal zone between the PF and SAF featured an elevated concentration of sei whales, and the area south of the PF and along the SAF was identified as an important feeding ground of sei whales in July from 2000 to 2007.

    Head and neck squamous cell carcinoma (HNSCC) has the potential for early metastasis and is associated with poor survival. Ano1 (Dog1) is an established and sensitive marker for the diagnosis of gastrointestinal stromal tumors (GIST) and has recently been identified as a Ca2+ activated Cl? channel. Although the ANO1 gene is located on the 11q13 locus, a region which is known to be amplified in different types of human carcinomas, a detailed analysis of Ano1 amplification and expression in HNSCC has not been performed. It is thus still unclear how Ano1 contributes to malignancy in HNSCC. We analyzed genomic amplification of the 11q13 locus and Ano1 together with Ano1-protein expression in a large collection of HNSCC samples. We detected a highly significant correlation between amplification and expression of Ano1 and showed that HNSCC patients with Ano1 protein expression have a poor overall survival. We further analyzed the expression of the Ano1 protein in more than 4?000 human samples from 80 different tumor types and 76 normal tissue types and detected that besides HNSCC and GISTs, Ano1 was rarely expressed in other tumor samples or healthy human tissues. In HNSCC cell lines, expression of Ano1 caused Ca2+ activated Cl? currents, which induced cell motility and cell migration in wound healing and in real time migration assays, respectively. In contrast, knockdown of Ano1 did not affect intracellular Ca2+ signaling and surprisingly did not reduce cell proliferation in BHY cells. Further, expression and activity of Ano1 strongly correlated with the ability of HNSCC cells to regulate their volume. Thus, poor survival in HNSCC patients is correlated with the presence of Ano1. Our results further suggest that Ano1 facilitates regulation of the cell volume and causes cell migration, which both can contribute to metastatic progression in HNSCC. PMID:22912841

    Background: Ano-rectal complaints are usually benign in origin. Most of the patients suffering with these disorders do not seek medical advice at an early stage due to embarrassment. It results in advancement of the disease and significant disturbance in the quality of life. Among the available treatment modalities of ano-rectal disorders (ARDs), K??ras?tra (medicated thread) appears to be the best in terms of relief and nonrecurrence. Aims and Objectives: The aim of this study is to provide evidence-based data about the practical application of K??ras?tra (medicated thread) in the management of ARDs. Materials and Methods: An ano-rectal operation theatre was established in September 2012, in association with the Government Ayurvedic Speciality Clinic at District Hospital, Rajahmundry, Andhra Pradesh, to facilitate the AYUSH services in Allopathic Hospitals. Present report includes the details of ARDs treated by K??ras?tra (Medicated thread) method during 20122013. A total of 127 ano-rectal cases were operated, which included 44 cases of hemorrhoids, 40 cases of fistula-in-ano, 39 cases of fissure-in-ano and three cases of peri-anal abscess. All the cases were analyzed as per the observations, subjective and objective parameters, and follow-up was carried out for a period of 6 months. Results: In the 127 ARDs treated, 45 patients suffering from hemorrhoids, 36 patients got complete relief, marked relief observed in 4 patients, moderate relief observed in 5 patients. In fistula-in-ano, out of 40 patients 29 patients got complete relief, marked relief was seen in 7 patients out of them 4 patients were referred to anti-tubercular treatment center, 4 patients left against medical advice. In fissure-in-ano-out of 39 patients, 32 patients got complete relief, 5 patients got marked relief, moderate relief observed in 2 patients. These results authenticate the effectiveness of K??ras?tra, no adverse effects or recurrence observed in any case. Conclusions: ARDs are efficiently treated by K??ras?tra technique with prompt symptomatic resolution and prevention of recurrence and complications.

    KMA(Korea Meteorological Agency) and KIGAM(Korea Institute of Geoscience and Mineral Resources) have started a project to construct EEWS(Earthquake Early Warning System) from 2007 in South Korea. After preliminary test of PRESTo, we have changed PRESToPLUS to make applicable it on K-SEIS(Korea-Speedy Earthquake Information System) enlarging the number of stations and study area belong to KIGAM and KMA around the Korean Peninsula. PRESToPLUS has been changed to be applied on K-SEIS with powerful performance allowing more than 100 stations real-time streaming and larger study area including off-shore areas around the southern part of the Korean Peninsula. For the modulation the code of PRESToPLUS has been revised in the Linux OS and Windows 64 bit machines respectively. Whole earthquake catalog was play-backed in PRESToPLUS in order to get parameterization to account for Korean seismicity and existing network. A new regression law for magnitude estimation (RTMag Module) was defined by extraction of Magnitude, hypocentral distance and Pd measured on 4s P-waves signal at all stations. The new law of RTMag is logPd= -4.012+0.583M-1.033logR. With extraction of PGD, PGA, PGV, epicentral distance at stations from the earthquake catalog we can derive new Ground Motion Prediction Equations to use in PGx prediction at target sites in PRESToPLUS. The new regression law is logPGA=0.615+0.7M-1.68log(R^2+100)^(1/2). Theoretical analysis of the number of triggered stations for all possible events across Korea was done to derive the best parameterization of time windows for the earthquake detection (Binder Module). After analysis of performance PRESToPLUS we can conclude 8 picks and 8 second condition might be best for reliable event detection with current station network setting.

    The Ca(2+)-activated Cl channel anoctamin-1 (Ano1; Tmem16A) plays a variety of physiological roles, including epithelial fluid secretion. Ano1 is activated by increases in intracellular Ca(2+), but there is uncertainty whether Ca(2+) binds directly to Ano1 or whether phosphorylation or additional Ca(2+)-binding subunits like calmodulin (CaM) are required. Here we show that CaM is not necessary for activation of Ano1 by Ca(2+) for the following reasons. (a) Exogenous CaM has no effect on Ano1 currents in inside-out excised patches. (b) Overexpression of Ca(2+)-insensitive mutants of CaM have no effect on Ano1 currents, whereas they eliminate the current mediated by the small-conductance Ca(2+)-activated K(+) (SK2) channel. (c) Ano1 does not coimmunoprecipitate with CaM, whereas SK2 does. Furthermore, Ano1 binds very weakly to CaM in pull-down assays. (d) Ano1 is activated in excised patches by low concentrations of Ba(2+), which does not activate CaM. In addition, we conclude that reversible phosphorylation/dephosphorylation is not required for current activation by Ca(2+) because the current can be repeatedly activated in excised patches in the absence of ATP or other high-energy compounds. Although Ano1 is blocked by the CaM inhibitor trifluoperazine (TFP), we propose that TFP inhibits the channel in a CaM-independent manner because TFP does not inhibit Ano1 when applied to the cytoplasmic side of excised patches. These experiments lead us to conclude that CaM is not required for activation of Ano1 by Ca(2+). Although CaM is not required for channel opening by Ca(2+), work of other investigators suggests that CaM may have effects in modulating the biophysical properties of the channel. PMID:24420770

    Members of the Anoctamin (Ano)/TMEM16A family have recently been identified as essential subunits of the Ca2+-activated chloride channel (CaCC). For example, Ano1 is highly expressed in multiple tissues including airway epithelia, where it acts as an apical conduit for transepithelial Cl? secretion and helps regulate lung liquid homeostasis and mucus clearance. However, little is known about the oligomerization of this protein in the plasma membrane. Thus, utilizing mCherry- and eGFP-tagged Ano1 constructs, we conducted biochemical and Frster resonance energy transfer (FRET)-based experiments to determine the quaternary structure of Ano1. FRET and co-immunoprecipitation studies revealed that tagged Ano1 subunits directly associated before they reached the plasma membrane. This association was not altered by changes in cytosolic Ca2+, suggesting that this is a fixed interaction. To determine the oligomeric structure of Ano1, we performed chemical cross-linking, non-denaturing PAGE, and electromobility shift assays, which revealed that Ano1 exists as a dimer. These data are the first to probe the quaternary structure of Ano1. Understanding the oligomeric nature of Ano1 is an essential step in the development of therapeutic drugs that could be useful in the treatment of cystic fibrosis. PMID:21056985

    LiNi0.5Mn1.5O4 spinel is considered one of the most promising cathodes for advanced lithium ion batteries. However, the operation potential of LiNi0.5Mn1.5O4, ~4.75 V, is beyond the high voltage limit of the state-of-art electrolyte, ~4.3 V. Here, using thin films of LiNi0.5Mn1.5O4 as a model material, we show evidence that an artificial solid electrolyte interphase (SEI) enables the use of this 5 V cathode with conventional carbonate electrolytes. A thin coating of Lipon (lithium phosphorus oxynitride) as an artificial SEI on LiNi0.5Mn1.5O4 could remedy the decomposition of the electrolyte. The thickness of the Lipon artificial SEI is optimized by balancing the protection and additional resistance. The strategy of artificial SEI on cathodes is expected to enable the wide application of other high voltage cathodes for lithium ion batteries.

    Modeling ground motions from multi-shot, delay-fired mining blasts is important to the understanding of their source characteristics such as spectrum modulation. MineSeis is a MATLAB{reg_sign} (a computer language) Graphical User Interface (GUI) program developed for the effective modeling of these multi-shot mining explosions. The program provides a convenient and interactive tool for modeling studies. Multi-shot, delay-fired mining blasts are modeled as the time-delayed linear superposition of identical single shot sources in the program. These single shots are in turn modeled as the combination of an isotropic explosion source and a spall source. Mueller and Murphy`s (1971) model for underground nuclear explosions is used as the explosion source model. A modification of Anandakrishnan et al.`s (1997) spall model is developed as the spall source model. Delays both due to the delay-firing and due to the single-shot location differences are taken into account in calculating the time delays of the superposition. Both synthetic and observed single-shot seismograms can be used to construct the superpositions. The program uses MATLAB GUI for input and output to facilitate user interaction with the program. With user provided source and path parameters, the program calculates and displays the source time functions, the single shot synthetic seismograms and the superimposed synthetic seismograms. In addition, the program provides tools so that the user can manipulate the results, such as filtering, zooming and creating hard copies.

    Objective. To determine the fecal incontinence and recurrence rate in patients with complex fistula in ano managed with cable tie seton at a tertiary care teaching hospital. Methods. This is a prospective case series of patients with complex anal fistula i.e. recurrent fistula or encircling >30% of external anal sphincter, managed with cable tie seton from March 2003 to March 2009. Patients were seen in the clinic after 72 hours of seton insertion under anesthesia and then every other week. Each time the cable-tie was tightened if found loose without anesthesia and incontinence was inquired according to wexner's score. Results. Seventy nine patients were treated during the study period with the age (mean standard deviation) of 41 10.6 years and. The seton was tightened with a median of six times (315 times range). Complete healing was achieved in 11.2 5.7 weeks. All the patients were followed for a minimum period of one year and none of the patients had any incontinence. Recurrence was found in 4 (5%) patients. Conclusion. The cable tie seton is safe, cost effective and low morbidity option for the treatment of complex fistulae-in-ano. It can, therefore, be recommended as the standard of treatment for complex fistulae-in-ano requiring the placement of a seton. PMID:22084768

    A model structure has been constructed for a monoclonal anti-dinitrophenyl antibody. The antibody, ANO2, has been sequenced and cloned (Anglister, J., Frey, T., & McConnell, H.M., 1984, Biochemistry 23, 1138-1142). Its amino acid sequence shows striking homology with the anti-lysozyme Fab fragments HyHel5 (83%) and HyHel10 (73%). Based on this homology, a model for the ANO2 variable heavy and variable light chain framework was constructed using a hybrid of the HyHel5 light chain and the HyHel10 heavy chain backbone, omitting the hypervariable loops. These coordinates were used as scaffolds for the model building of ANO2. The CONGEN conformational sampling algorithm (Bruccoleri, R.E. & Karplus, M., 1987, Biopolymers 26, 127-196) was used to model the six hypervariable loops that contain the antigen-combining site. All the possible conformations of the loop backbones were constructed and the best loop structures were selected using a combination of the CHARMM potential energy function and evaluation of the solvent-accessible surface area of the conformers. The order in which the loops were searched was carried out based on the relative locations of the loops with reference to the framework of the beta-barrel, namely, L2-H1-L3-H2-H3-L1. The model structures thus obtained were compared to the high resolution X-ray structure (Brnger, A.T., Leahy, D.J., Hynes, T.R., & Fox, R.O., 1991, J. Mol. Biol. 221, 239-256). PMID:1303765

  18. Development of a SeisComP3 module for detecting micro earthquakes and its application to ocean bottom network data

    Seismic data from local size networks and a semi-global size network are being received at Jamstec. In order to systematically handle the data of the different network sizes, we attempted to apply SeisComp3, which is an earthquake monitoring system originally designed for detecting earthquakes or tsunamis in global or semi-global scales. On the other hand, it has been reported that many micro earthquakes are recorded in one of the networks, DONET. DONET is a local size network of ocean bottom seismometers deployed offshore of Kii peninsula, the northern part of Nankai trough. It is important to efficiently detect and list these earthquakes for the full utilization of the network data, especially toward understanding the shallow subduction zone dynamics. However, since the earthquake detection algorithm used in SeisComP3 focuses more on locating relatively large size earthquakes and minimizing the chance of detecting false events, some of the micro earthquakes do not get detected by the existing function of SeisComP3. Here, we developed a new SeisComP3 module, which binds signals detected at multiple stations within a certain distance and time span. We applied this module, which we call 'binder', to one daylong DONET data and listed all the events obtained at the frequency range between 2 and 30 Hz. We confirmed that the binder is useful for detecting micro earthquakes. Moreover, one of the binder's advantages is that it works without assumptions on the velocity profile, thus it detected enigmatic events whose epicenters are located on the Kumano Basin and whose signal propagates at the velocity of around 1.5km/s throughout the stations placed on the basin. No clear P arrivals were observed for these events. The finding demonstrates the possibility of the binder to become a useful tool to further explore the data and to find out more of different types of events, which have not been identified yet.

    The calcium-activated chloride channel ANO1 regulates multiple physiological processes. However, little is known about the mechanism of channel gating and regulation of ANO1 activity. Using a high-throughput, random mutagenesis-based variomics screen, we generated and functionally characterized ?6000 ANO1 mutants and identified novel mutations that affected channel activity, intracellular trafficking, or localization of ANO1. Mutations such as S741T increased ANO1 calcium sensitivity and rendered ANO1 calcium gating voltage-independent, demonstrating a critical role of the re-entrant loop in coupling calcium and voltage sensitivity of ANO1 and hence in regulating ANO1 activation. Our data present the first unbiased and comprehensive study of the structure-function relationship of ANO1. The novel ANO1 mutants reported have diverse functional characteristics, providing new tools to study ANO1 function in biological systems, paving the path for a better understanding of the function of ANO1 and its role in health and diseases.

    Gnathodiaphyseal dysplasia (GDD) is an autosomal dominant syndrome characterized by frequent bone fractures at a young age, bowing of tubular bones and cemento-osseus lesions of the jawbones. Anoctamin 5 (ANO5) belongs to the anoctamin protein family that includes calcium-activated chloride channels. However, recent data together with our own experiments reported here add weight to the hypothesis that ANO5 may not function as calcium-activated chloride channel. By sequencing the entire ANO5 gene coding region and untranslated regions in a large Italian GDD family, we found a novel missense mutation causing the p.Thr513Ile substitution. The mutation segregates with the disease in the family and has never been described in any database as a polymorphism. To date, only two mutations on the same cysteine residue at position 356 of ANO5 amino-acid sequence have been described in GDD families. As ANO5 has also been found to be mutated in two different forms of muscular dystrophy, the finding of this third mutation in GDD adds clues to the role of ANO5 in these disorders. PMID:23047743

  4. The Ca2+-activated Cl- channel ANO1/TMEM16A regulates primary ciliogenesis.

    Many cells possess a single, nonmotile, primary cilium highly enriched in receptors and sensory transduction machinery that plays crucial roles in cellular morphogenesis. Although sensory transduction requires ion channels, relatively little is known about ion channels in the primary cilium (with the exception of TRPP2). Here we show that the Ca(2+)-activated Cl ((-)) channel anoctamin-1 (ANO1/TMEM16A) is located in the primary cilium and that blocking its channel function pharmacologically or knocking it down with short hairpin RNA interferes with ciliogenesis. Before ciliogenesis, the channel becomes organized into a torus-shaped structure ("the nimbus") enriched in proteins required for ciliogenesis, including the small GTPases Cdc42 and Arl13b and the exocyst complex component Sec6. The nimbus excludes F-actin and coincides with a ring of acetylated microtubules. The nimbus appears to form before, or independent of, apical docking of the mother centriole. Our data support a model in which the nimbus provides a scaffold for staging of ciliary components for assembly very early in ciliogenesis and chloride transport by ANO1/TMEM16A is required for the genesis or maintenance of primary cilia.

    In this study, we combined linkage analysis with whole-exome sequencing of two individuals to identify candidate causal variants in a moderately-sized UK kindred exhibiting autosomal-dominant inheritance of craniocervical dystonia. Subsequent screening of these candidate causal variants in a large number of familial and sporadic cases of cervical dystonia led to the identification of a total of six putatively pathogenic mutations in ANO3, a gene encoding a predicted Ca2+-gated chloride channel that we show to be highly expressed in the striatum. Functional studies using Ca2+ imaging in case and control fibroblasts demonstrated clear abnormalities in endoplasmic-reticulum-dependent Ca2+ signaling. We conclude that mutations in ANO3 are a cause of autosomal-dominant craniocervical dystonia. The locus DYT23 has been reserved as a synonym for this gene. The implication of an ion channel in the pathogenesis of dystonia provides insights into an alternative mechanism that opens fresh avenues for further research. PMID:23200863

    Abdominoperineal resection (APR) is indicated for low rectal/ano-rectal cancers. It necessitates fastidious pelvic dissection posing certain operative difficulties. We present the surgical challenges in a unique case of a patient presenting with a low rectal adenocarcinoma and a synchronous pelvic schwannomas, both requiring resection. A 71-year-old gentleman presented for surveillance colonoscopy following previous excision of colonic polyps. This investigation revealed a polypoid mass at the ano-rectal junction which was histologically proven as an adenocarcinoma with high-grade dysplasia. A staging computed tomography scan revealed an incidental 10 15 cm homogeneous, pre-sacral mass. After meticulous operative planning, the patient underwent successful open resection of this mass and concurrent APR for his low rectal lesion. This case demonstrates a rare presentation of a low rectal adenocarcinoma and concurrent pelvic schwannoma. We discuss the technical difficulties encountered in the management of such complex pelvic tumours and highlight the successful outcomes of the synchronous resection. PMID:24876323

    We report a case of mucinous adenocarcinoma arising in the perianal soft tissue in association with chronic fistula-in-ano in a 43-year-old man who had a relapse of perianal pain and bloody discharge after six years of defaulted follow-up. He underwent magnetic resonance (MR) and computed tomography imaging with correct identification of the disease entity on imaging. Mesh-like septations and an enhancing solid component with high diffusion-weighted imaging (DWI) and intermediate apparent diffusion coefficient signals were observed. He underwent abdominoperineal resection of the tumour but succumbed due to postoperative complications. Literature on the MR imaging features of this tumour remains scarce. We highlight the MR imaging features, including those seen on DWI, which were useful in making the correct diagnosis. Though uncommon, this would be an important condition to recognise since assessment of fistula-in-ano by MR imaging is considered to be the standard of care in current clinical practice. The clinical features of this entity are also briefly discussed. PMID:23268160

    Since anoctamin 1 ANO1 (TMEM16A) was found to be a molecular component of Ca2+-activated Cl? channels, its role in tumorigenesis has gained attention at a fast pace. ANO1 overexpression frequently occurs in the cancer tissues along with 11q13 chromosome amplification. Poor prognosis of many types of cancers has been closely correlated with ANO1 gene amplification and protein overexpression. ANO1 is now considered an excellent biomarker for certain cancers. Recent research suggests that it is the channel function of ANO1 that is involved in the tumorigenesis. However, how the overexpression of the functional ANO1 causes malignant transformation of tissues via signaling pathways, for example, MAPK remains to be investigated. Clarification of the reasons in future will avail to make ANO1 as a target for cancer treatment. PMID:24639373

    Traditional Medicine has its own importance for the treatment of various medical and surgical diseases irrespective of tremendous development of modern medicine. There are number of diseases were after repeated surgery. Fistula-in ano is one such condition which is prone to recurrence even after repeated surgery and can be effectively treated by Ayurvedic medicines. An extensive work has been done on the treatment of Bhagandara by Kshara sutra exploring various aspects of the problem and finding our the solution to them1. the present study is related to similar type of medicated thread known as Aragvadadi Sutra which has been mentioned by sushruta in Bhagandara. It consists of Aragvadha (Cassia fistula), Haridra (Curcuma longa), Agaru (Aquilaria agalocha), Madhu (Honey) and Ghrita (Ghee). This is the first non-caustic thread being tried on different types of Bhagandara. Especially it is a painless thread, non-irritant and very useful in sensitive patients like children, females and elders. PMID:22556930

    The solid electrolyte interface (SEI) formation on the surface of LiMn{sub 2}O{sub 4} electrodes during room temperature charge-discharge cycling was studied using soft X-ray absorption spectroscopy at the Fluorine (F) K-edge. LiMn{sub 2}O{sub 4} electrodes without any binder were prepared by electrostatic spray deposition to eliminate the signal originating from the PVDF binder in the F K-edge X-ray absorption spectra. The F K-edge absorption spectra show that the SEI layer forms at a very early stage of cycling. SEI growth takes place during discharge. In addition, LiF formation is accelerated if the discharge step follows a charge step. The F K-edge absorption spectra suggest that the major component of the SEI is LiF.

  12. SM1.3 Seismic Centers Data Acquisition: an introduction to Antelope, EarthWorm, SeisComP and their usage around the world

    2010-05-01

    Many medium to big size seismic data centers around the world are facing the same question: which software to use to acquire seismic data in real-time? A home-made or a commercial one? Both choices have pros and cons. The in-house development of software usually requires an increased investment in human resources rather than a financial investment. However, the advantage of fully accomplishing your own needs could be put in danger when the software engineer quits the job! Commercial software offers the advantage of being maintained, but it may require both a considerable financial investment and training. The main seismic software data acquisition suites available nowadays are the public domain SeisComP and EarthWorm packages and the commercial package Antelope. Nanometrics, Guralp and RefTek also provide seismic data acquisition software, but they are mainly intended for single station/network acquisition. Antelope is a software package for real-time acquisition and processing of seismic network data, with its roots in the academic seismological community. The software is developed by Boulder Real Time Technology (BRTT) and commercialized by Kinemetrics. It is used by IRIS affiliates for off-line data processing and it is the main acquisition tool for the USArray program and data centers in Europe like the ORFEUS Data Center, OGS (Italy), ZAMG (Austria), ARSO (Slovenia) and GFU (Czech Republic). SeisComP was originally developed for the GEOFON global network to provide a system for data acquisition, data exchange (SeedLink protocol) and automatic processing. It has evolved into to a widely distributed, networked seismographic system for data acquisition and real-time data exchange over Internet and is supported by ORFEUS as the standard seismic data acquisition tool in Europe. SeisComP3 is the next generation of the software and was developed for the German Indonesian Tsunami Early Warning System (GITEWS). SeisComP is licensed by GFZ (free of charge) and maintained by a private company (GEMPA). EarthWorm was originally developed by United States Geological Survey (USGS) to exchange data with the Canadian seismologists. Its is now used by several institution around the world. It is maintained and developed by a commercial software house, ISTI.

    Background: Parikartika resembles fissure-in-ano which is very common among all ano-rectal disorders. In Ayurvedic texts, Parikartika is described as a complication of Vamana and Virechana as well as complication of Atisara. Ksharasutra was proved successful in the management of fistula-in-ano, piles, and there is a need to try its efficacy in fissure-in-ano. Aim: To evaluate the role of Ksharasutra suturing (KSS) in fissure bed in chronic fissure-in-ano. Materials and Methods: Total 100 patients of chronic fissure-in-ano were selected and randomly divided into two groups (50 in each group). In group-A, patients were undergone by KSS; while in patients of Group-B Lord's anal dilatation followed by KSS was done under spinal anesthesia. The KSS was done once and after slough out of Ksharasutra, the wound was treated for 4 weeks and assessment of the result was done on the basis of gradation adopted. Results: The pain relief on 14th day in Group-A was 86% while in Group-B 100% was observed. As on 7th day in Group-A, oozing was stopped in 68% patients, while in Group-B, oozing was stopped in 82% patients. On 21st day, Group-B showed more healing (85%) as compared to Group-A (69%). In this study 68% of patients were cured. Conclusion: In Group-B (KSS with Lord's anal dilatation) patients were cured early as compared to patients of Group-A (KSS alone). PMID:25558158

  16. The Multi-factor Predictive Seis &Gis Model of Ecological, Genetical, Population Health Risk and Bio-geodynamic Processes In Geopathogenic Zones

    NASA Astrophysics Data System (ADS)

    Bondarenko, Y.

    I. Goal and Scope. Human birth rate decrease, death-rate growth and increase of mu- tagenic deviations risk take place in geopathogenic and anthropogenic hazard zones. Such zones create unfavourable conditions for reproductive process of future genera- tions. These negative trends should be considered as a protective answer of the com- plex biosocial system to the appearance of natural and anthropogenic risk factors that are unfavourable for human health. The major goals of scientific evaluation and de- crease of risk of appearance of hazardous processes on the territory of Dnipropetrovsk, along with creation of the multi-factor predictive Spirit-Energy-Information Space "SEIS" & GIS Model of ecological, genetical and population health risk in connection with dangerous bio-geodynamic processes, were: multi-factor modeling and correla- tion of natural and anthropogenic environmental changes and those of human health; determination of indicators that show the risk of destruction structures appearance on different levels of organization and functioning of the city ecosystem (geophys- ical and geochemical fields, soil, hydrosphere, atmosphere, biosphere); analysis of regularities of natural, anthropogenic, and biological rhythms' interactions. II. Meth- ods. The long spatio-temporal researches (Y. Bondarenko, 1996, 2000) have proved that the ecological, genetic and epidemiological processes are in connection with de- velopment of dangerous bio-geophysical and bio-geodynamic processes. Mathemat- ical processing of space photos, lithogeochemical and geophysical maps with use of JEIS o and ERDAS o computer systems was executed at the first stage of forma- tion of multi-layer geoinformation model "Dnipropetrovsk ARC View GIS o. The multi-factor nonlinear correlation between solar activity and cosmic ray variations, geophysical, geodynamic, geochemical, atmospheric, technological, biological, socio- economical processes and oncologic case rate frequency, general and primary popula- tion sickness cases in Dnipropetrovsk City (1.2 million persons) are described by the multi-factor predictive SEIS & GIS model of geopathogenic zones that determines the human health risk and hazards. Results and Conclusions. We have created the SEIS system and multi-factor predictive SEIS model for the analysis of phase-metric spatio- 1 temporal nonlinear correlation and variations of rhythms of human health, ecological, genetic, epidemiological risks, demographic, socio-economic, bio-geophysical, bio- geodynamic processes in geopathogenic hazard zones. Cosmophotomaps "CPM" of vegetation index, anthropogenic-landscape and landscape-geophysical human health risk of Dnipropetrovsk City present synthesis-based elements of multi-layer GIS, which include multispectral images SPOT o, maps of different geophysical, geochem- ical, anthropogenic and citogenic risk factors, maps of integral oncologic case rate frequency, general and primary population sickness cases for administrative districts. Results of multi-layer spatio-temporal correlation of geophysical field parameters and variations of population sickness rate rhythms have enabled us to state grounds and to develop medico-biological and bio-geodynamic classification of geopathogenic zones. Bio-geodynamic model has served to define contours of anthropogenic-landscape and landscape-geophysical human health risk in Dnipropetrovsk City. Biorhythmic vari- ations give foundation for understanding physiological mechanisms of organism`s adaptation to extreme helio-geophysical and bio-geodynamic environmental condi- tions, which are dictated by changes in Multi-factor Correlation Stress Field "MCSF" with deformation of 5D SEIS. Interaction between organism and environment results in continuous superpositioning of external (exogenic) Nuclear-Molecular-Cristallic "NMC" MCSF rhythms on internal (endogenic) Nuclear-Molecular-Cellular "NMCl" MCSF rhythms. Their resonance wave (energy-information) integration and disinte- gration are responsible for struc

    The 2004 Mid-Atlantic Ridge (MAR)-ECO expedition on the R.V. G.O. Sars provided the first opportunity to correlate oceanic distributions of cetaceans with synoptic acoustic (ADCP to 700 m depth, multi-beam echosounders) measurements of high-resolution, three-dimensional (3D) potential habitat (spatial scale<100 km). The identified habitat features were tested with independent observations from the Icelandic combined cetacean and redfish cruises in 2001 and 2003 using data from a 3D ocean general circulation model of the MAR region (Regional Oceans Modelling System (ROMS) model 5 km resolution). The spatial autocorrelation of sampled encounter rates of sperm Physeter macrocephalus and sei whales Balaenoptera borealis indicated scale-dependent variability in the distribution of both species. Despite the large area surveyed, the observations of both species exhibited a strong small-scale structure (range parameter 20-50 km), indicating affinities to cross-seamount or cross-frontal structures. Potential cross-seamount and cross-frontal habitat structures were derived from the acoustic transect data by analysing fine-scale gradients in the 3D flow patterns and bathymetry, including interactions between frontal and topographic parameters. PLS regression was used to determine the potential habitat drivers of sperm and sei whales, both during the G.O. Sars cruise and during the Icelandic cruises in 2001 and 2003. The selected parameters, which reflected flow gradients interacting with the steep topography, were finally applied for modelling the habitat suitability of both target species along the northern MAR using Ecological Niche Factor Analysis. The results suggest aggregations of sperm and sei whales along the MAR are primarily associated with fine-scale frontal processes interacting with the topography in the upper 100 m of the water column just north of the Sub-Polar Front (SPF) and the Charlie-Gibbs Fracture Zone (CGFZ). As moderate and high habitat suitabilities were estimated only for areas downstream from the SPF, the findings suggest that the animals capitalise on secondary production maintained by enhanced primary production associated with the frontal processes in the upper part of the water column in the CGFZ and at the Faraday Seamounts. Further studies are encouraged to evaluate the importance of the bio-physical coupling, and the significance of small-scale frontal processes in the surface and subsurface waters north of the SPF for the transfer of energy to higher trophic levels in the North Atlantic.

    Highlights: Black-Right-Pointing-Pointer We model the operation of an MBT plant in Greece based on LCA. Black-Right-Pointing-Pointer We compare four different MBT operating scenarios (among them and with landfilling). Black-Right-Pointing-Pointer Even the current operation of the MBT plant is preferable to landfilling. Black-Right-Pointing-Pointer Utilization of the MBT compost and metals generates the most environmental gains. Black-Right-Pointing-Pointer Thermal exploitation of RDF improves further the environmental performance of the plant. - Abstract: The aim of this paper is the application of Life Cycle Assessment to the operation of the MBT facility of Ano Liossia in the region of Attica in Greece. The region of Attica is home to almost half the population of Greece and the management of its waste is a major issue. In order to explicitly analyze the operation of the MBT plant, five scenarios were generated. Actual operation data of the MBT plant for the year 2008 were provided by the region of Attica and the LCA modeling was performed via the SimaPro 5.1 software while impact assessment was performed utilizing the Eco-indicator'99 method. The results of our analysis indicate that even the current operation of the MBT plant is preferable to landfilling. Among the scenarios of MBT operation, the one with complete utilization of the MBT outputs, i.e. compost, RDF, ferrous and non-ferrous metals, is the one that generates the most environmental gains. Our analysis indicates that the exploitation of RDF via incineration is the key factor towards improving the environmental performance of the MBT plant. Our findings provide a quantitative understanding of the MBT plant. Interpretation of results showed that proper operation of the modern waste management systems can lead to substantial reduction of environmental impacts and savings of resources.

    A recent report (Vermeer et al. in Am J Hum Genet 87:813-819, 2010) implicated for the first time the ANO10 gene in the genetic basis of autosomal recessive cerebellar ataxias. One of the three described families were Roma/Gypsies from Serbia, where the affected individuals were homozygous for the truncating p.Leu384fs mutation and displayed distinct phenotypic features (Vermeer et al. in Am J Hum Genet 87:813-819, 2010). Based on the history and population genetics of the Roma/Gypsies, we hypothesised that p.Leu384fs could be another founder mutation in this population, whose identification in a larger number of genetically homogeneous patients will contribute to defining the phenotypic spectrum of the disorder. Here, we describe additional patients from neighbouring Bulgaria, outlining invariable ANO10-ataxia features and confirming global intellectual decline as part of the phenotype resulting from complete Anactomin 10 deficit.

Methods of Study: Case files of all patients managed in University of Maiduguri Teaching Hospital and Federal Medical Center of Yola and Gombe from January, 2007 to December, 2011 were retrieved from Medical Record Departments and other Hospital Records. These were analyzed for demographic, clinical and pathological variables, the type of treatment and follow-up. Results: A total of 10 men with a mean age of 50.5 years (35-60) were managed in the period of study. Nearly, 50% of the patients were farmers, 30% businessmen and 20% were civil servant. 7 (70%) of these patients presented with Fournier's gangrene within 4 weeks of development of fistula-in-ano and the rest within 8 weeks. 4 (40%) of these patients had inadequate drainage of their perianal abscess and 2 (20%) had incision and drainage. Another 4 (40%) had spontaneously rupture of the perianal abscess. 6 (60%) of the fistula-in-ano was submuscular, 30% subcutaneous and 10% were complex or recurrent. Nearly, 20% of patients had fistulotomy and seton application for adequate drainage. Mucosal advancement flap was performed in 5 (50%) and fistulotomy in 3 (30%) patients. Another 30% had fistulotomy and continuing sitz bath. Conclusion: Cryptoglandular infection is an important cause of perianal abscesses and fistula-in-ano and if poorly managed results in Fournier's gangrene. Early broad spectrum parenteral antibiotic therapy and primary surgical treatment can prevent Fournier's gangrene. PMID:24497752

  3. Predicting the occurrence of embolic events: an analysis of 1456 episodes of infective endocarditis from the Italian Study on Endocarditis (SEI)

    Background Embolic events are a major cause of morbidity and mortality in patients with infective endocarditis. We analyzed the database of the prospective cohort study SEI in order to identify factors associated with the occurrence of embolic events and to develop a scoring system for the assessment of the risk of embolism. Methods We retrospectively analyzed 1456 episodes of infective endocarditis from the multicenter study SEI. Predictors of embolism were identified. Risk factors identified at multivariate analysis as predictive of embolism in left-sided endocarditis, were used for the development of a risk score: 1 point was assigned to each risk factor (total risk score range: minimum 0 points; maximum 2 points). Three categories were defined by the score: low (0 points), intermediate (1 point), or high risk (2 points); the probability of embolic events per risk category was calculated for each day on treatment (day 0 through day 30). Results There were 499 episodes of infective endocarditis (34%) that were complicated by???1 embolic event. Most embolic events occurred early in the clinical course (first week of therapy: 15.5 episodes per 1000 patient days; second week: 3.7 episodes per 1000 patient days). In the total cohort, the factors associated with the occurrence of embolism at multivariate analysis were prosthetic valve localization (odds ratio, 1.84), right-sided endocarditis (odds ratio, 3.93), Staphylococcus aureus etiology (odds ratio, 2.23) and vegetation size???13mm (odds ratio, 1.86). In left-sided endocarditis, Staphylococcus aureus etiology (odds ratio, 2.1) and vegetation size???13mm (odds ratio, 2.1) were independently associated with embolic events; the 30-day cumulative incidence of embolism varied with risk score category (low risk, 12%; intermediate risk, 25%; high risk, 38%; p?

    Anoctamin-1 (Ano1) is a widely expressed protein responsible for endogenous Ca(2+)-activated Cl(-) currents. Ano1 is overexpressed in cancer. Differential expression of transcriptional variants is also found in other diseases. However, the mechanisms underlying regulation of Ano1 are unknown. This study identifies the Ano1 promoter and defines a mechanism for regulating its expression. Next-generation RNA sequencing (RNA-seq) analysis in human gastric muscle found a new exon upstream of the reported exon 1 and identified a promoter proximal to this new exon. Reporter assays in human embryonic kidney 293 cells showed a 6.7 2.1-fold increase in activity over empty vector. Treatment with a known regulator of Ano1 expression, IL-4, increased promoter activity by 1.6 0.02-fold over untreated cells. The promoter region contained putative binding sites for multiple transcription factors including signal transducer and activator of transcription 6 (STAT6), a downstream effector of IL-4. Chromatin immunoprecipitation (ChIP) experiments on T84 cells, which endogenously express Ano1, showed a 2.1 0.12-fold increase in binding of STAT6 to P0 after IL-4 treatment. These results were confirmed by mutagenesis, expression, and RNA interference techniques. This work allows deeper understanding of the regulation of Ano1 in physiology and as a potential therapeutic target in a variety of diseases. PMID:25351986

    We report that ANO1 (also known as TMEM16A) Ca2+-activated Cl? channels in small neurons from dorsal root ganglia are preferentially activated by particular pools of intracellular Ca2+. These ANO1 channels can be selectively activated by the G protein-coupled receptor (GPCR)-induced release of Ca2+ from intracellular stores, but not by Ca2+ influx through voltage-gated Ca2+ channels. This ability to discriminate between Ca2+ pools was achieved by the tethering of ANO1-containing plasma membrane domains, which also contained GPCRs such as bradykinin receptor-2 and protease-activated receptor-2, to juxtamembrane regions of the endoplasmic reticulum. Interaction of the C-terminus and the first intracellular loop of ANO1 with IP3R1 (inositol 1,4,5-trisphosphate receptor 1) contributed to the tethering. Disruption of membrane microdomains blocked the ANO1 and IP3R1 interaction and resulted in the loss of coupling between GPCR signaling and ANO1. The junctional signaling complex enabled ANO1-mediated excitation in response to specific Ca2+ signals rather than to global changes in intracellular Ca2+. PMID:23982204

    Large scale (up to 5 kt) chemical blasts are routinely conducted by mining and quarry industries around the world to remove overburden or to fragment rocks. Because of their ability to trigger the future International Monitoring System (IMS) of the Comprehensive Test Ban Treaty (CTBT), these blasts are monitored and studied by verification seismologists for the purpose of discriminating them from possible clandestine nuclear tests. One important component of these studies is the modeling of ground motions from these blasts with theoretical and empirical source models. The modeling exercises provide physical bases to regional discriminants and help to explain the observed signal characteristics. The program MineSeis has been developed to implement the synthetic seismogram modeling of multi-shot blast sources with the linear superposition of single shot sources. Single shot sources used in the modeling are the spherical explosion plus spall model mentioned here. Mueller and Murphy`s (1971) model is used as the spherical explosion model. A modification of Anandakrishnan et al.`s (1997) spall model is developed for the spall component. The program is implemented with the MATLAB{reg_sign} Graphical User Interface (GUI), providing the user with easy, interactive control of the calculation.

    Abstract Caveolin (Cav)-1 is an integral membrane protein of caveolae playing a crucial role in various signal transduction pathways. Caveolae represent the sites for calcium entry and storage especially in smooth muscle cells (SMC) and interstitial cells of Cajal (ICC). Cav-1?/? mice lack caveolae and show abnormalities in pacing and contractile activity of the small intestine. Presently, we investigated, by transmission electron microscopy (TEM) and immunohistochemistry, whether the absence of Cav-1 in Cav-1?/? mouse small intestine affects ICC, SMC and neuronal morphology, the expression of NK1 and NK2 receptors, and of Ano1 (also called Dog1 or TMEM16A), an essential molecule for slow wave activity in gastrointestinal muscles. ICC were also labelled with c-Kit and tachykinergic neurons with Substance P (SP). In Cav-1?/? mice: (i) ICC were Ano1-negative but maintained c-Kit expression, (ii) NK1 and NK2 receptor immunoreactivity was more intense and, in the SMC, mainly intracytoplasmatic, (iii) SP-immunoreactivity was significantly reduced. Under TEM: (i) ICC, SMC and telocytes lacked typical caveolae but had few and large flask-shaped vesicles we called large-sized caveolae; (ii) SMC and ICC contained an extraordinary high number of mitochondria, (iii) neurons were unchanged. To maintain intestinal motility, loss of caveolae and reduced calcium availability in Cav-1knockout mice seem to be balanced by a highly increased number of mitochondria in ICC and SMC. Loss of Ano-1 expression, decrease of SP content and consequently overexpression of NK receptors suggest that all these molecules are Cav-1associated proteins. PMID:21535398

    The effects of fluoroethylene carbonate (FEC) on the electrochemical performance of the LiCoO2 cathode were investigated by galvanostatic charge-discharge testing and cyclic voltammetry (CV). It was found that FEC has a positive effect on cycling stability and also improves cell performance. We also studied solid electrolyte interface (SEI) film on the LiCoO2 cathode, using X-ray photoelectron spectroscopy (XPS) and 2D correlation spectroscopy. The 2D correlation XPS spectra showed that, initially, the polyvinylidene fluoride (PVdF) binder and electrolyte components are decomposed, after which SEI components are formed on the LiCoO2 cathode surface. In the FEC-containing electrolyte, the polycarbonate components are more abundant than in the FEC-free electrolyte. The formed carbonates in SEI film can act as Li+-conducting materials in reducing the electrode/electrolyte interfacial impedance. This hypothesis is supported by the results of an electrochemical impedance spectrum (EIS) analysis.

    We report a case of chronic arthritis of the right hip joint in an otherwise healthy young male athlete as a complication of inadequately treated anal fistula. A young male athlete presented with symptoms of right hip pain and difficulty in walking and intermittent fever for 2?months. He had a history of perianal abscess drainage. On examination he was found to have a tender right hip joint with severe restriction of movements. He was also found to have a partially drained right ischiorectal abscess. X-ray and MRI of the hip joint revealed chronic arthritis of the right hip joint, which was communicating with a complex fistula-in-ano. He underwent a diversion sigmoid colostomy and right ischiorectal abscess drainage along with appropriate antibiotics with a plan for definitive hip joint procedure later. He was lost to follow-up and succumbed to severe perianal sepsis within a few months. PMID:25414226

    Highlights: Black-Right-Pointing-Pointer T16A{sub inh}-A01 blocked Ano1 currents in HEK cells expressing Ano1. Black-Right-Pointing-Pointer T16A{sub inh}-A01 reduced proliferation in ICC primary cultures and CFPAC-1 cell line. Black-Right-Pointing-Pointer T16A{sub inh}-A01 reduced proliferation of ICC in intact smooth muscle strips. -- Abstract: Background: Ion channels play important roles in regulation of cellular proliferation. Ano1 (TMEM16A) is a Ca{sup 2+}-activated Cl{sup -} channel expressed in several tumors and cell types. In the muscle layers of the gastrointestinal tract Ano1 is selectively expressed in interstitial cells of Cajal (ICC) and appears to be required for normal gastrointestinal slow wave electrical activity. However, Ano1 is expressed in all classes of ICC, including those that do not generate slow waves suggesting that Ano1 may have other functions. Indeed, a role for Ano1 in regulating proliferation of tumors and ICC has been recently suggested. Recently, a high-throughput screen identified a small molecule, T16A{sub inh}-A01 as a specific inhibitor of Ano1. Aim: To investigate the effect of the T16A{sub inh}-A01 inhibitor on proliferation in ICC and in the Ano1-expressing human pancreatic cancer cell line CFPAC-1. Methods: Inhibition of Ano1 was demonstrated by whole cell voltage clamp recordings of currents in cells transfected with full-length human Ano1. The effect of T16A{sub inh}-A01 on ICC proliferation was examined in situ in organotypic cultures of intact mouse small intestinal smooth muscle strips and in primary cell cultures prepared from these tissues. ICC were identified by Kit immunoreactivity. Proliferating ICC and CFPAC-1 cells were identified by immunoreactivity for the nuclear antigen Ki67 or EdU incorporation, respectively. Results: T16A{sub inh}-A01 inhibited Ca{sup 2+}-activated Cl{sup -} currents by 60% at 10 {mu}M in a voltage-independent fashion. Proliferation of ICC was significantly reduced in primary cultures from BALB/c mice following treatment with T16A{sub inh}-A01. Proliferation of the CFPAC-1 human cell-line was also reduced by T16A{sub inh}-A01. In organotypic cultures of smooth muscle strips from mouse jejunum, the proliferation of ICC was reduced but the total number of proliferating cells/confocal stack was not affected, suggesting that the inhibitory effect was specific for ICC. Conclusions: The selective Ano1 inhibitor T16A{sub inh}-A01 inhibited Ca{sup 2+}-activated Cl{sup -} currents, reduced the number of proliferating ICC in culture and inhibited proliferation in the pancreatic cancer cell line CFPAC-1. These data support the notion that chloride channels in general and Ano1 in particular are involved in the regulation of proliferation.

  12. New Constraints on Buried Triassic Basins of the Eastern North American Margin and Implications for Regional Tectonics from Reanalysis of SeisData6 Seismic Profile

    The Eastern North American Margin (ENAM) is most significant due to the complexity and regional extent of this mature Mesozoic passive margin rift system encompassing: (1) a large volume and regional extent of related magmatism, (2) a preserved complete stratigraphic column that records the post-rift evolution in several basins, (3) preserved lithospheric-scale pre-rift structures including Paleozoic sutures, and (4) a wide-range of geological, geochemical, and geophysical studies both onshore and offshore. The short-lived but most voluminous magmatic event associated with the initiation of rifting, the Central Atlantic Magmatic Province (CAMP), is one of the most significant magmatic events in North America. The South Georgia Rift (SGR) basin is believed to be the largest and probably the most geologically complex Mesozoic graben of the ENAM formed during crustal extension associated with the breakup of Pangea and later opening of the North Atlantic Ocean. The separation of the African and North American plates, the formation of the Atlantic Ocean and the associated zones of weakness in eastern North America have been stated as the initial events in the breakup of Pangea. At least four major unanswered questions of regional tectonic significance derive from a previous study of the USGS SeisData6 seismic profile across the Coastal Plain of South East Georgia and are now addressed through reprocessing. These issues are: (1) the stratigraphy, structural composition, extent and thickness of this buried basin which have remained unknown, (2) whether or not the SGR basin is connected with the Riddleville and Dunbarton basins in Georgia and South Carolina, (3) whether or not the Augusta fault, an inferred crustal scale thrust fault which approximately represents the Piedmont-Coastal Plain boundary in Georgia and South Carolina, extends underneath the Coastal Plain sediments, and (4) weather there is evidence of CAMP basalt flows or sills within the SGR basin along this transect. A key significant discovery of this study is the substantiation of the presence of a buried Triassic basin inferred to be the subsurface convergence of the Riddleville and Dunbarton basins. Both basins appear to be subsidiaries of the main SGR basin. The SGR basin is about 2.2 km deep, 170 km wide and it appears to be bounded in the south-east by normal faults resembling graben-like structures. Basin-bounding faults reactivated as reverse faults during Cretaceous and Cenozoic times are common in many of the buried Mesozoic rift basins of the Southern Appalachians. The basin fill is mostly sedimentary rocks and no basalt was encountered. Absence of basalt in this area implies that erosion, uplift and possibly fault reactivation may have limited the regional extent of voluminous basaltic flows extruded during ENAM's magmatism. Seismically, we found no evidence to suggest that the Augusta fault extends underneath the Coastal Plain sediments in the study area. Based on correlation of seismic and well data, we interpret the lack of reflections in the NW-end of the profile to be due to the presence of non-reflective metamorphic rocks of the Piedmont Province.

    Bhagandara (Fistula in Ano) at modern parlance is a common anorectal condition prevalent in the populations worldwide and its prevalence is second highest after Arsha (hemorrhoids). Kshara Sutra (K.S.) is one of the chief modality in the treatment of Bhagandara in Ayurvedic science. Exploration of the new plants for the preparation of Kshara as a better substitute to Apamarga Kshara is the need of the hour. To find out an effective alternative to Apamarga K.S. in view of easy processing, a Snuhi Ksheera Sutra without any Kshara and the Tilanala K.S. were opted for their clinical evaluation. Total 33 cases of Bhagandara were divided randomly into 3 groups, having 11 patients in each group. In Group A, Snuhi Ksheera Sutra; in Group B, Tilanala K.S. and in Group C, Apamarga K.S. were used. Assessment was done on objective (Unit Cutting Time - UCT) and subjective parameters. Statistically insignificant difference was observed in the efficacy of treatment by subjective parameters like pain, discharge, etc. between the three groups. It was found that Tilanala K.S. showed higher UCT (9.76 days) while lower in Snuhi Ksheera Sutra (7.42 days) as compared to Apamarga K.S. (8.82 days). Thus Tilanala K.S. can be used as a substitute for Apamarga K.S. and Snuhi Ksheera Sutra can be employed in the recurrent fibrosed cases of Bhagandara. PMID:23049190

    Actinide separation in spent nuclear fuel reprocessing is essential for the closed nuclear fuel cycle. Organophosphorus reagents have been found to exhibit strong affinities for actinides in experiments. In this work, the extraction complexes of AnO2(n+) (An = U, Np; n = 1, 2) with the traditional organophosphorus ligand HDEHP (di-(2-ethylhexyl)phosphoric acid) have been investigated using density functional theory together with scalar-relativistic effective core potentials (ECPs) for actinide elements. According to our calculations, the HDEHP dimer prefers to act as a bidentate ligand in most of the studied complexes. HDEHP ligands show a higher extraction ability for An(vi) over An(v), and the formation of Np(vi) complexes is slightly more favorable than those of U(vi) analogues, which is mainly attributed to the stronger donor-acceptor interaction in Np(vi) complexes. The intramolecular hydrogen bonds play a significant role in the stability of the 1?:?1 type complexes AnO2(HL)2(NO3)2 (L = DEHP(-)). Moreover, AnO2(HL)2(NO3)2 are the most stable species in nitrate-rich acid solutions, while at low nitric acid concentrations, the complexing reaction of AnO2(H2O)5(2+) + 2(HL)2 ? AnO2(HL2)2 + 2H(+) + 5H2O is probably the dominant reaction in the extraction process. Our results can help to understand the speciation of actinyl complexes in real solvent extraction of actinides with HDEHP at the molecular level. PMID:25598207

    Limb girdle muscular dystrophy type 2L or anoctaminopathy is a condition mainly characterized by adult onset proximal lower limb muscular weakness and raised CK values, due to recessive ANO5 gene mutations. An exon 5 founder mutation (c.191dupA) has been identified in most of the British and German LGMD2L patients so far reported. We aimed to further investigate the prevalence and spectrum of ANO5 gene mutations and related clinical phenotypes, by screening 205 undiagnosed patients referred to our molecular service with a clinical suspicion of anoctaminopathy. A total of 42 unrelated patients had two ANO5 mutations (21%), whereas 14 carried a single change. We identified 34 pathogenic changes, 15 of which are novel. The c.191dupA mutation represents 61% of mutated alleles and appears to be less prevalent in non-Northern European populations. Retrospective clinical analysis corroborates the prevalently proximal lower limb phenotype, the male predominance and absence of major cardiac or respiratory involvement. Identification of cases with isolated hyperCKaemia and very late symptomatic male and female subjects confirms the extension of the phenotypic spectrum of the disease. Anoctaminopathy appears to be one of the most common adult muscular dystrophies in Northern Europe, with a prevalence of about 20%-25% in unselected undiagnosed cases. PMID:23606453

    The electronic states of the actinide dioxides AnO2 (with An = U, Np, Pu, Am, and Cm) are investigated employing first-principles calculations within the framework of the local density approximation +U (LDA+U) approach, implemented in a full-potential linearized augmented plane-wave scheme. A systematic analysis of the An-5f states is performed which provides intuitive connections between the electronic structures and the local crystalline fields of the f states in the AnO2 series. Particularly the mechanisms leading to the experimentally observed insulating ground states are investigated. These are found to be caused by the strong spin-orbit and Coulomb interactions of the 5f orbitals; however, as a result of the different configurations, this mechanism works in distinctly different ways for each of the AnO2 compounds. In agreement with experimental observations, the nonmagnetic states of plutonium and curium dioxide are computed to be insulating, whereas those of uranium, neptunium, and americium dioxides require additional symmetry breaking to reproduce the insulator ground states, a condition which is met with magnetic phase transitions. We show that the occupancy of the An-f orbitals is closely connected to each of the appearing insulating mechanisms. We furthermore investigate the detailed constitution of the noncollinear multipolar moments for transverse 3q magnetic ordered states in UO2 and longitudinal 3q high-rank multipolar ordered states in NpO2 and AmO2.

    BACKGROUND AND PURPOSE Although atypical smooth muscle cells (SMCs) in the proximal renal pelvis are thought to generate the pacemaker signals that drive pyeloureteric peristalsis, their location and electrical properties remain obscure. EXPERIMENTAL APPROACH Standard patch clamp, intracellular microelectrode and immunohistochemistry techniques were used. To unequivocally identify SMCs, transgenic mice with enhanced yellow fluorescent protein (eYFP) expressed in cells containing ?-smooth muscle actin (?-SMA) were sometimes used. KEY RESULTS Atypical SMCs were distinguished from typical SMCs by the absence of both a transient 4-aminopyridine-sensitive K+ current (IKA) and spontaneous transient outward currents (STOCs) upon the opening of large-conductance Ca2+-activated K+ (BK) channels. Many typical SMCs displayed a slowly activating, slowly decaying Cl- current blocked by niflumic acid (NFA). Immunostaining for KV4.3 and ANO1/ TMEM16A Cl- channel subunits co-localized with ?-SMA immunoreactive product predominately in the distal renal pelvis. Atypical SMCs fired spontaneous inward currents that were either selective for Cl- and blocked by NFA, or cation-selective and blocked by La3+. ?-SMA- interstitial cells (ICs) were distinguished by the presence of a Xe991-sensitive KV7 current, BK channel STOCs and Cl- selective, NFA-sensitive spontaneous transient inward currents (STICs). Intense ANO1/ TMEM16A and KV7.5 immunostaining was present in Kit-?-SMA- ICs in the suburothelial and adventitial regions of the renal pelvis. CONCLUSIONS AND IMPLICATIONS We conclude that KV4.3+?-SMA+ SMCs are typical SMCs that facilitate muscle wall contraction, that ANO1/ TMEM16A and KV7.5 immunoreactivity may be selective markers of Kit- ICs and that atypical SMCs which discharge spontaneous inward currents are the pelviureteric pacemakers.

    The Anopheles arabiensis genetic sexing strain ANO IPCL1 was developed based on a dieldrin resistant mutation. The strain has been shown to be practical and reliable in terms of female elimination by dieldrin treatments at larval stages, but has provided some difficulties when treatments were applied at the egg stage. The high natural sterility of this strain has advantages and disadvantages in both mass rearing and the sterilization process. In addition, its recombination rate, although relatively low, poses a threat of strain deterioration if left unchecked in a mass-rearing setting. The males of the ANO IPCL1 have been shown to be equally competitive as lab-reared males of the wild-type Dongola strain, but competitiveness decreased by half when irradiated with 75 Gya dose conferring >98% sterility. More controversial issues surround the use of dieldrina highly persistent organochlorine that is known to bioaccumulate in the food chain. The prospective use of large volumes of dieldrin in a mass-rearing facility and the retention of its residues by the male mosquitoes makes the use of the strain in the context of the sterile insect technique against this vector highly questionable, and therefore its implementation at a large scale cannot be recommended.

    The use of nuclear electric propulsion (NEP) and nuclear thermal propulsion (NTP) for transportation to the moon and Mars is examined, and the use on Mars and moon bases of thermal conversion subsystems based on either a Brayton or a Stirling cycle is examined. It is shown that both cycles are attractive alternatives for those applications where continuous field operation is desired. Nuclear power systems have a clear advantage with regard to the moon and a lesser one with regard to Mars.

  13. Comparison of EPA's QMS to SEI's CMMI.

    EPA and other government organizations make decisions based on environmental measurements. How good are the data? How well are the data generators performing? What measurements apply to them? How can the data life cycle processes be improved so data generators can continually provide the best data? EPA's Quality Management System requirements go beyond evaluation of environmental data quality itself to examine systems associated with production, collection, processing (validation/verification), transfer, reduction, storage, and retrieval of data throughout a life cycle. This QMS specifies minimum quality requirements for particular environmental programs. But how can you measure and compare programs that go well beyond the minimum, towards optimal quality? This paper compares EPA's requirements for Quality Management Systems (R2) and Project Plans (R5) to the Software Engineering Institute Capability Maturity Model (CMMISM). The CMMISM model provides for growth (staged or continuous) and a comprehensive assessment that is not yet provided in EPA's R2 or R5. Properly implemented, the CMMISM model serves as a quality framework for integrating and aligning organizational processes and implementing a program of continual process improvements. It identifies process areas ("things to do"), and provides measures of performance ("how well things are done") against specific goals and practices. CMMISM uses a Systems Engineering Management approach, built on process models, that helps identify "how good" the system is. Goodness is defined as stages in a complete model for optimal operation. CMMISM provides two methods for evaluating the goodness of the project. The Staged model in CMMISM provides a Maturity Level that is a well-defined evolutionary plateau describing the manner in which a specified set of processes are performed. As the organization advances in maturity, these levels become more defined and processes are tailored for specific project needs. The other method is called the Continuous Model in CMMISM, and it allows you to achieve Capability Levels. These are used to describe how well each project is doing in relationship to the different process areas. There are six Capability Levels from 0-5 that apply to individual process areas. Organizations using the Capability Level approach can select individual process areas that are important to specific projects and work to improve the processes. Improving capability in individual process areas raises the organization's overall quality of products delivered. The Continuous Model, unlike the Staged Model, lets you pick higher maturity level process areas before completing all of the ones below. Environmental measurement programs need to focus on the quality of the systems where data are collected, processed, transferred, and so forth. DynCorp built on the quality foundation from our experience with R2 to successfully implement CMMISM practices in the development of Forms II Lite and other applications. DynCorp is now migrating to the CMMISM model that has evolved from the existing CMM model. The CMMISM model focuses on the full cycle of Requirements Management from identification, development, collection, refinement, analysis, and validation throughout a project life cycle. It also has a more refined focus on the identification, development, collection, analysis, and evaluation of meaningful measurements, so the results can be used to improve a process or product.

  14. CFTR and Anoctamin 1 (ANO1) contribute to cAMP amplified exocytosis and insulin secretion in human and murine pancreatic beta-cells

    PubMed Central

    2014-01-01

    Background Mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene lead to the disease cystic fibrosis (CF). Although patients with CF often have disturbances in glucose metabolism including impaired insulin release, no previous studies have tested the hypothesis that CFTR has a biological function in pancreatic beta-cells. Methods Experiments were performed on islets and single beta-cells from human donors and NMRI-mice. Detection of CFTR was investigated using PCR and confocal microscopy. Effects on insulin secretion were measured with radioimmunoassay (RIA). The patch-clamp technique was used to measure ion channel currents and calcium-dependent exocytosis (as changes in membrane capacitance) on single cells with high temporal resolution. Analysis of ultrastructure was done on transmission electron microscopy (TEM) images. Results We detected the presence of CFTR and measured a small CFTR conductance in both human and mouse beta-cells. The augmentation of insulin secretion at 16.7mM glucose by activation of CFTR by cAMP (forskolin (FSK) or GLP-1) was significantly inhibited when CFTR antagonists (GlyH-101 and/or CFTRinh-172) were added. Likewise, capacitance measurements demonstrated reduced cAMP-dependent exocytosis upon CFTR-inhibition, concomitant with a decreased number of docked insulin granules. Finally, our studies demonstrate that CFTR act upstream of the chloride channel Anoctamin 1 (ANO1; TMEM16A) in the regulation of cAMP- and glucose-stimulated insulin secretion. Conclusion Our work demonstrates a novel function for CFTR as a regulator of pancreatic beta-cell insulin secretion and exocytosis, and put forward a role for CFTR as regulator of ANO1 and downstream priming of insulin granules prior to fusion and release of insulin. The pronounced regulatory effect of CFTR on insulin secretion is consistent with impaired insulin secretion in patients with CF. PMID:24885604

    Autosomal-recessive cerebellar ataxias comprise a clinically and genetically heterogeneous group of neurodegenerative disorders. In contrast to their dominant counterparts, unraveling the molecular background of these ataxias has proven to be more complicated and the currently known mutations provide incomplete coverage for genotyping of patients. By combining SNP array-based linkage analysis and targeted resequencing of relevant sequences in the linkage interval with the use of next-generation sequencing technology, we identified a mutation in a gene and have shown its association with autosomal-recessive cerebellar ataxia. In a Dutch consanguineous family with three affected siblings a homozygous 12.5 Mb region on chromosome 3 was targeted by array-based sequence capture. Prioritization of all detected sequence variants led to four candidate genes, one of which contained a variant with a high base pair conservation score (phyloP score: 5.26). This variant was a leucine-to-arginine substitution in the DUF 590 domain of a 16K transmembrane protein, a putative calcium-activated chloride channel encoded by anoctamin 10 (ANO10). The analysis of ANO10 by Sanger sequencing revealed three additional mutations: a homozygous mutation (c.1150_1151del [p.Leu384fs]) in a Serbian family and a compound-heterozygous splice-site mutation (c.1476+1G>T) and a frameshift mutation (c.1604del [p.Leu535X]) in a French family. This illustrates the power of using initial homozygosity mapping with next-generation sequencing technology to identify genes involved in autosomal-recessive diseases. Moreover, identifying a putative calcium-dependent chloride channel involved in cerebellar ataxia adds another pathway to the list of pathophysiological mechanisms that may cause cerebellar ataxia.

    The parallel components of static electric dipole polarizabilities have been calculated for the lowest lying spin-orbit states of the penta- and hexavalent oxidation states of the actinides (An) U, Np, and Pu, in both their atomic and molecular diyl ion forms (An5+/6+ and AnO2+/2+) using the numerical finite-field technique within a four-component relativistic framework. The four-component Dirac-Hartree-Fock method formed the reference for MP2 and CCSD(T) calculations, while multireference Fock space coupled-cluster (FSCC), intermediate Hamiltonian Fock space coupled-cluster (IH-FSCC) and Kramers restricted configuration interaction (KRCI) methods were used to incorporate additional electron correlation. It is observed that electron correlation has significant (5 a.u.3) impact upon the parallel component of the polarizabilities of the diyls. To the best of our knowledge, these quantities have not been previously reported and they can serve as reference values in the determination of various electronic and response properties (for example intermolecular forces, optical properties, etc.) relevant to the nuclear fuel cycle and material science applications. The highest quality numbers for the parallel components (?zz) of the polarizability for the lowest ? levels corresponding to the ground electronic states are (in a.u.3) 44.15 and 41.17 for UO2+ and UO22+, respectively, 45.64 and 41.42 for NpO2+ and NpO22+, respectively, and 47.15 for the PuO2+ ion.

    Research developed with 95 students of the 6th year of elementary education in a public school of Uberlndia, Minas Gerais. It was a continuous work from February to December 2013, which led the students to participate in activities of observation of the environment, specifically the sky, analyzing the changes occurred. We focused on the study of variations in temperature, rainfall, day length, variations in the size of the shadows and changes in the aspect of the Moon. Our focus of analysis targeted the discussion of the knowledge that these students had about the topics indicated and as they entered the stage during the implementation of the proposal. The results showed a limited perception that students have of their environment, however, lately expanded due to the undertaken activities, especially in relation to the Moon. Working with systematic measure procedures reveals the careful handling of data so that they become understandable to students, and working with the shadows points towards the students first understand how shadows are formed, and then apply this knowledge to Astronomy. Finally, we conclude that the lived process consisted of an initial step of a work that should be encouraged for the subsequent years of training of these students.

    Os aglomerados abertos so objetos de grande valor para o estudo da dinmica da Galxia devido esses objetos terem uma faixa de idade relativamente ampla. O trabalho visa estudar a dinmica da estrutura espiral da Galxia principalmente atravs do uso desses aglomerados, uma vez que o estudo da cinemtica desses objetos fundamental para esse objetivo. Nosso grupo trabalha no sentido de construir uma base de dados de aglomerados abertos contendo coordenadas, distncia, idade, movimentos prprios e velocidades radiais e j disponibiliza uma nova verso do catlogo de aglomerados abertos o qual uma compilao de edies anteriores, principalmente Lynga (1987), Mermilliod (1995) e ESO-B (Lauberts 1982). Nossa amostra possui cerca de 1630 aglomerados, mas nem todos os parmetros acima citados foram determinados em sua totalidade. Para determinarmos esses parmetros, derivamos as cores intrnsecas das estrelas membro de cada aglomerado a partir de seus tipos espectrais (busca feita no SIMBAD) obtendo assim o excesso de cor individual. A distribuio dos excessos de cor foi ento utilizada para derivarmos o avermelhamento mdio para cada aglomerado. De maneira similar, os tipos espectrais foram usados para estimar as magnitudes absolutas, e com as magnitudes absolutas e aparentes determinamos a respectiva distribuio do mdulo de distncia e finalmente a distncia. Para determinar as idades foram confeccionados os diagramas cor-magnitude das estrelas de cada aglomerado onde foram superpostas a Seqncia Principal de Idade Zero (ZAMS). Superpomos a ZAMS de Schmidt-Kaler e iscronas de composio solar. Essas iscronas foram usadas para determinao das idades dos aglomerados. Uma vez que no temos ainda resultados finais, apresentamos ento alguns diagramas cor-magnitude os quais foram usados para determinao, principalmente, da distncia e idade dos aglomerados.

    We present a systematic comparison of the lattice structures, electronic density of states, and band gaps of actinide dioxides, AnO2 (An=Th, Pa, U, Np, Pu, and Am) predicted by the Heyd-Scuseria-Ernzerhof screened hybrid density functional (HSE) with the self-consistent inclusion of spin-orbit coupling (SOC). The computed HSE lattice constants and band gaps of AnO2 are in consistently good agreement with the available experimental data across the series, and differ little from earlier HSE results without SOC. ThO2 is a simple band insulator (f 0), while PaO2, UO2, and NpO2 are predicted to be Mott insulators.

    Uma exploso solar uma variao rpida e intensa do brilho que ocorre nas chamadas regies ativas da atmosfera, constitudas por um plasma magnetizado com intensa induo magntica. Os modelos de exploses solares atuais, discutidos na literatura, apresentam caractersticas de aprisionamento e precipitao de eltrons em ambientes magnticos simplificados. Neste trabalho, nos propusemos a separar a emisso dos eltrons aprisionados da emisso dos eltrons em precipitao apenas a partir da emisso em microondas, melhorando portanto o controle sobre o conjunto de parmetros inferidos. A emisso em microondas da populao em precipitao bastante fraca e portanto da nossa base de dados de 130 exploses observadas pelo Rdio Polarmetro de Nobeyama, em sete freqncias, apenas para 32 foi possvel separar as duas componentes de emisso com uma boa razo sinal/rudo. A partir de estudos das escalas de tempo das emisses devidas variao gradual da emisso no aprisionamento e da variao rpida da emisso dos eltrons em precipitao foi possvel obter a separao utilizando um filtro temporal nas emisses resultantes. Em nossa anlise destas exploses estudamos os espectros girossincrotrnicos da emisso gradual, a qual associamos provir do topo dos arcos magnticos e da emisso de variao rpida associada aos eltrons em precipitao. Estes espectros foram calculados e dos quais inferimos que a induo magntica efetiva do topo e dos ps foi em mdia, Btopo = 236 G e Bps = 577 G, inferidas das freqncias de pico dos espectros em ntopo = 11,8 GHz e nps = 14,6 GHz com leve anisotropia (pequeno alargamento espectral). O ndice espectral da distribuio no-trmica de eltrons d, inferido do ndice espectral de ftons da emisso em regime opticamente fino, foi de dtopo = 3,3 e dps = 3,9. Estes parmetros so tpicos da maioria das anlises realizadas em ambiente nico de emisso e a relao dos ndices espectrais, dps > dtopo prioriza as interpretaes com difuso em ngulo de passo devida a colises Coulombianas. Nesta difuso o dficit de eltrons energticos na precipitao seria uma conseqncia natural da dependncia em e-3/2 das colises eltron-prton (onde e a energia dos eltrons).

  12. Assessment of the Olfactory Function in Italian Patients with Type 3 von Willebrand Disease Caused by a Homozygous 253 Kb Deletion Involving VWF and TMEM16B/ANO2.

    Type 3 Von Willebrand disease is an autosomal recessive disease caused by the virtual absence of the von Willebrand factor (VWF). A rare 253 kb gene deletion on chromosome 12, identified only in Italian and German families, involves both the VWF gene and the N-terminus of the neighbouring TMEM16B/ANO2 gene, a member of the family named transmembrane 16 (TMEM16) or anoctamin (ANO). TMEM16B is a calcium-activated chloride channel expressed in the olfactory epithelium. As a patient homozygous for the 253 kb deletion has been reported to have an olfactory impairment possibly related to the partial deletion of TMEM16B, we assessed the olfactory function in other patients using the University of Pennsylvania Smell Identification Test (UPSIT). The average UPSIT score of 4 homozygous patients was significantly lower than that of 5 healthy subjects with similar sex, age and education. However, 4 other members of the same family, 3 heterozygous for the deletion and 1 wild type, had a slightly reduced olfactory function indicating that socio-cultural or other factors were likely to be responsible for the observed difference. These results show that the ability to identify odorants of the homozygous patients for the deletion was not significantly different from that of the other members of the family, showing that the 253 kb deletion does not affect the olfactory performance. As other genes may compensate for the lack of TMEM16B, we identified some predicted functional partners from in silico studies of the protein-protein network of TMEM16B. Calculation of diversity for the corresponding genes for individuals of the 1000 Genomes Project showed that TMEM16B has the highest level of diversity among all genes of the network, indicating that TMEM16B may not be under purifying selection and suggesting that other genes in the network could compensate for its function for olfactory ability.

    Nuclear (fission) thermal propulsion has been identified as a critical technology for a manned mission to Mars by the year 2019. Facilities are required that will support ground tests to qualify the nuclear rocket engine design, which must support a realistic thermal and neutronic environment in which the fuel elements will operate at a fraction of the power for a flight weight reactor/engine. This paper describes the design of a fuel element ground test facility, with a strong emphasis on safety and economy. The details of major structures and support systems of the facility are discussed, and a design diagram of the test facility structures is presented.

    Solar arrays can provide reliable space power, but do not operate when there is no solar energy. Photovoltaic arrays can also convert laser energy with high efficiency. One proposal to reduce the required mass of energy storage required is to illuminate the photovoltaic arrays by a ground laser system. It is proposed to locate large lasers on cloud-free sites at one or more ground locations, and use large lenses or mirrors with adaptive optical correction to reduce the beam spread due to diffraction or atmospheric turbulence. During the eclipse periods or lunar night, the lasers illuminate the solar arrays to a level sufficient to provide operating power.

    This study was based on a prospective cohort of university staff in Rio de Janeiro, Brazil (the Estudo Pr-Sade). In this article the association between socioeconomic position (SEP) earlier and later in life and age at menopause is investigated. The main indicators investigated were for earlier SEP: mother's and father's schooling; stature; leg and trunk length. For later SEP they were: schooling; home and/or car ownership. Median age at menopause was estimated and survival curves were generated by the Kaplan-Meier method, while the association between indicators of SEP and age at menopause was explored by means of Cox semiparametric models. Associations were found between earlier SEP - represented by trunk length - and earlier menopause and between later SEP - represented by the indicator 'present schooling' - and earlier menopause. The association between earlier and later SEP was confirmed. Adverse situations over the life course can impact age at menopause and related health outcomes. PMID:22040212

    The fate of actinyl species in the environment is closely linked to oxidation state, since the reduction of An(VI) to An(IV) greatly decreases their mobility due to the precipitation of the relatively insoluble An(IV) species. Here we study the mechanism of the reduction of [AnO(2)](2+) (An = U, Np, Pu) both in aqueous solution and by Fe(II) containing proteins and mineral surfaces, using density functional theory calculations. We find a disproportionation mechanism involving a An(V)-An(V) cation-cation complex, and we have investigated how these complexes are formed in the different environments. We find that the behaviour of U and Pu complexes are similar, but the reduction of Np(V) to Np(IV) would seems to be more difficult, in line with the experimental finding that Np(V) is generally more stable than U(V) or Pu(V). Although the models we have used are somewhat idealised, our calculations suggest that there are strong similarities between the biotic and abiotic reduction pathways. PMID:21837318

    The bonding in the highly homoatomic np pi-np pi (n > or = 3)-bonded S2I42+ (three sigma + two pi bonds), the Se-I pi-bonded Se2I42+ (four sigma + one pi bonds), and their higher-energy isomers have been studied using modern DFT and ab initio calculations and theoretical analysis methods: atoms in molecules (AIM), molecular orbital (MO), natural bond orbital (NBO), and valence bond (VB) analyses, giving their relative energies, theoretical bond orders, and atomic charges. The aim of this work was to seek theory-based answers to four main questions: (1) Are the previously proposed simple pi*-pi* bonding models valid for S2I42+ and Se2I42+? (2) What accounts for the difference in the structures of S2I42+ and Se2I42+? (3) Why are the classically bonded isolobal P2I4 and As2I4 structures not adopted? (4) Is the high experimentally observed S-S bond order supported by theoretical bond orders, and how does it relate to high bond orders between other heavier main group elements? The AIM analysis confirmed the high bond orders and established that the weak bonds observed in S2I42+ and Se2I42+ are real and the bonding in these cations is covalent in nature. The full MO analysis confirmed that S2I42+ contains three sigma and two pi bonds, that the positive charge is essentially equally distributed over all atoms, that the bonding between S2 and two I2+ units in S2I42+ is best described by two mutually perpendicular 4c2e pi*-pi* bonds, and that in Se2I42+, two SeI2+ moieties are joined by a 6c2e pi*-pi* bond, both in agreement with previously suggested models. The VB treatment provided a complementary approach to MO analysis and provided insight how the formation of the weak bonds affects the other bonds. The NBO analysis and the calculated AIM charges showed that the minimization of the electrostatic repulsion between EI2+ units (E = S, Se) and the delocalization of the positive charge are the main factors that explain why the nonclassical structures are favored for S2I42+ and Se2I42+. The difference in the structures of S2I42+ and Se2I42+ is related to the high strength of the S-S pi bond compared to the weak S-I sigma bond and the additional stabilization from increased delocalization of positive charge in the structure of S2I42+ compared to the structure of Se2I42+. The investigation of the E2X42+ series (E = S, Se, Te; X = Cl, Br, I) revealed that only S2I42+ adopts the highly np pi-np pi (n > or = 3)-bonded structure, while all other dications favor the pi-bonded Se2I42+ structure. Theoretical bond order calculations for S2I42+ confirm the previously presented experimentally based bond orders for S-S (2.1-2.3) and I-I (1.3-1.5) bonds. The S-S bond is determined to have the highest reported S-S bond order in an isolated compound and has a bond order that is either similar to or slightly less than the Si-Si bond order in the proposed triply bonded [(Me3Si)2CH]2(iPr)SiSi triple bond SiSi(iPr)[CH(SiMe3)2]2 depending on the definition of bond orders used.

    Although previous studies show that robotic telescopes have the potential to enhance student learning, there is comparatively little research that focuses on teacher perceptions of this technology. This study investigates: "what is the academic merit of using SLOOH robotic telescopes to teach astronomy as perceived by science teachers?" Our sample consists of nine science teachers of students aged 13-18 years. Pre- and post-tests, interviews, and surveys were collected during two weeks of a summer online course about robotic telescopes. While pre and post-tests do not reveal a statistically significant gain in astronomy content knowledge, analysis of qualitative data reveals five themes which describe the most important aspects of using SLOOH according to participants: "Images," "Interface," "Classroom Application," "Instructor Impact," and "Logistical Issues." Analysis of these themes suggests that SLOOH can provide an interactive and social learning environment with capabilities to incorporate crossdisciplinary themes. Embora estudos anteriores mostram que os telescpios robticos tm o potencial de melhorar a aprendizagem dos alunos, h relativamente pouca investigao focada nas percepes de professores a respeito desta tecnologia.

    The Lyndon B. Johnson Space Center Automation and Robotics Division has developed a simulation tool for use in evaluating the feasibility and effectiveness of proposed candidate mission concepts, such as the First Lunar Outpost design reference missions. The tool helps in defining requirements for such missions at the beginning of the definition activities and can be applied iteratively thereafter on a short cycle basis as changes are made to the mission definition. The simulation is applicable to the amount and capabilities of automation and robotics; number and skills of crew; amount of engineering work, science, and in-space materials utilization to be accomplished; impact of provision for maintenance and repair; and flight schedules and manifests. The simulation accounts for supply and demand of resources to accomplish tasks and accounts for elapsed time in carrying out mission processes and tasks.

    1992-01-01

    Existing robotic rover technologies at Sandia National Laboratories (SNL) can be applied toward the realization of a robotic lunar rover mission in the near term. Recent activities at the SNL-RVR have demonstrated the utility of existing rover technologies for performing remote field geology tasks similar to those envisioned on a robotic lunar rover mission. Specific technologies demonstrated include low-data-rate teleoperation, multivehicle control, remote site and sample inspection, standard bandwidth stereo vision, and autonomous path following based on both internal dead reckoning and an external position location update system. These activities serve to support the use of robotic rovers for an early return to the lunar surface by demonstrating capabilities that are attainable with off-the-shelf technology and existing control techniques. The breadth of technical activities at SNL provides many supporting technology areas for robotic rover development. These range from core competency areas and microsensor fabrication facilities, to actual space qualification of flight components that are designed and fabricated in-house.

    The electrochemical quartz crystal microbalance (EQCM) andcyclic voltammetry have been applied simultaneously to characterizeelectron-beam deposited carbon film electrodes in LiClO4 orLiPF6-containing mixed electrolytes of ethylene carbonate (EC) anddimethyl carbonate (DMC). The structure of the carbon electrode was foundto be amorphous/disordered using Raman spectroscopy. Cyclic voltammetryin LiClO4 / EC+DMC demonstrated features typical of Liintercalation/deintercalation into/from the disordered carbon electrode,and EQCM showed a corresponding mass increase/decrease. Contrary to thecase of LiClO4 / EC+DMC electrolyte, LiPF6/EC+DMC electrolyte showed noLi deintercalation out of the thin-film carbon electrode. Combined EQCMand spectroscopic ellipsometry data were compared, and the solidelectrolyte interphase density after the first cycle in LiClO4 /EC+DMCwas estimated to be 1.3 g/cm3.

    Concepts relevant to the development of an evolvable information management system are examined in terms of support for the Space Exploration Initiative. The issues of interoperability within NASA and industry initiatives are studied including the Open Systems Interconnection standard and the operating system of the Open Software Foundation. The requirements of partitioning functionality into separate areas are determined with attention given to the infrastructure required to ensure system-wide compliance. The need for a decision-making context is a key to the distributed implementation of the program, and this environment is concluded to be next step in developing an evolvable, interoperable, and securable support network.

  7. Relation of the lunar power system to the SEI program and to landers

    Criswell, David R.; Waldron, Robert D.

    The people of Earth will need more than 20,000 billion watts (GWe) of electric power by 2050 for a high level of prosperity. Power needs in the 22nd Century could exceed 100,000 GWe. By 2100 the total quantity of thermal energy used could fully deplete the known inventory (10(exp 7) GWt-Y) of all non-renewable sources on Earth except for deuterium and hydrogen for use in proposed fusion reactors. The labor, capital, and mass of power plants required to produce 1 GWe-Y of energy from present-day power plants is summarized. Fossil and nuclear plants respectively consume 80 to 190 M$ and 12 to 48 M$ of fuel per GWe-Y. The Lunar Power System (LPS) uses solar power bases on the moon to beam electric power to Earth. The LPS in the figure supplies load-following power to rectennas on Earth. Additional solar power conversion units are located across the lunar limb from their respective Earthward transmitting stations. LPS can be augmented by mirrors in polar orbit about the moon. The construction of rectennas on Earth determines the base cost (0.001s$/kWe-H) of LPS power. A manned International Lunar Base (ILB) can accelerate the development of LPS by providing the initial transportation and habitation facilities and base operations. ILB can greatly reduce up front costs and risks by emplacing a moderate scale LPS (1-100 GWe). LPS can accelerate the development of the ILB by providing greater funding than is reasonable to expect for purely scientific research. An international ILB/LPS program can foster world trust and prosperity.

    Six geothermal spring sites were selected on the basis of preliminary investigations conducted in Honduras over the last decade and were evaluated in terms of their development potential. Of the six, the Platanares and San Ignacio sites have high base temperatures and high surface fluid discharge rates and appear to have the best potential for further development as sources of electrical power. A third site, Azacualpa, has a high enough base temperature and discharge rate to be considered as a back-up, but the logistical problems involved in geophysical surveys make it less attractive than the two primary sites. Of the remaining three sites, Pavana may be a source of direct-use heat for local agricultural processing. Sambo Creek and El Olivar have either severe logistical problems that would impede further investigation and development or base temperatures and flow rates that are too low to warrant detailed investigation at this time.

  4. Subsurface Deformation in the Gangetic Plain - First results from the BrahmaSeis multichannel seismic survey on Bangladesh Rivers

    In Bangladesh, the northeastern boundary of the Indian-Asian collision zone is buried under thick delta sediments, delivered in huge volumes by the Ganges-Brahmaputra-Meghna river system. Monsoon-induced erosion provided several tens of meters of Holocene sediments to a subsiding delta plain, and it therefore remains a challenge to reconstruct the plate boundary, fault planes and main deformational styles and phases. While structural investigations with seismic methods on land are particularly difficult in the country, the distinctly elevated water level after the peak monsoon season provided the opportunity of a water seismic survey, utilizing marine seismic equipment and approaches. As part of the BanglaPIRE project, a first multichannel seismic survey had been carried out in September 2011 particularly on the rivers Meghna and Jamuna to find and map indications for subsurface deformation and the associated response of the sediment dispersal system during the late Quaternary development of the Gangetic delta plain. Using a high-resolution 48-channel streamer and a micro GI-Gun with 0.1 L volume, supported by two small diving compressors, continuous airgun profiles were acquired in several daily stretches along both rivers northward to the Indian border. Major challenges were, among others, a lack of navigational fixpoints in a rapidly changing delta and river landscape, the lack of clearly defined strata in a predominantly sandy environment, and the widespread occurrence of large amounts of shallow gas. In the northernmost stretch of the survey, the Dauki Fault, bounding the Shillong Plateau uplift on the southern side, is supposed to be covered by sediment in the slowly subsiding Sylhet Basin. On the Meghna river in central Bangladesh, the westernmost extent of the Indo-Burman Fold Belt was assumed. And on Jamuna, the western extension of the Dauki Fault and its interaction with the main river system is as unclear. The acquired multichannel seismic data, using shot rates on the order of 5 to 8 seconds, were sufficiently dense to achieve a horizontal resolution between 1 and 5 meters, and vertical resolution is on the order of 1 meter. Preliminary processing has revealed several areas, where pronounced deformation can be derived from underlying pre-Holocene strata geometries, revealing anticlines and reflector truncation at the base of the river plain sediments. In particular the Jamuna N-S transect completely images this Holocene base reflector. In the northernmost survey lines on Jamuna, it seems that the assumed position of the Dauki Fault finds it expression in subsurface deformation, an anticline geometry as well as steps in the Holocene base reflector.

    O universo em que vivemos possui segredos jamais imaginados pelo homem, fruto da pequena proporo que ocupamos diante de um cosmos infinito. A astronomia funciona como um instrumento que sacia a sede humana em desvendar esses segredos, estudando as galxias, quasares, pulsares alm da existncia de todos os elementos que preenchem o espao csmico, o vcuo, no mais vazio como se pensou em outros tempos. A mdia explora esse campo de forma mstica e tambm cientfica. A difuso adequada e dentro dos padres educacionais vigentes, de conceitos astronmicos, se faz necessria, devido sua presena nos contedos escolares, centros de cincia e na mdia, de modo geral. A reforma do Currculo Bsico da Escola Pblica da maioria dos Estados brasileiros introduziu conceitos astronmicos desde a pr-escola at o Ensino Mdio. Num estudo realizado com 1.032 alunos do Ensino Mdio de seis escolas estaduais, revelou-se atravs da aplicao de um questionrio que abordava conheciment os bsicos em astronomia, como estes foram adquiridos e qual era a infra-estrutura oferecida pela escola: para 66,2% dos entrevistados o professor j fez alguma apresentao a respeito de astronomia. O presente estudo revelou tambm que 44,5% dos alunos entrevistados adquiriram seus conhecimentos astronmicos na escola, 28,1% atravs da televiso e 27,4% afirmaram que seus conhecimentos foram obtidos atravs de outros tipos de mdia (internet, filmes e revistas). Embora o estudo revele claramente que h certo equilbrio na forma em que os alunos obtiveram seus conhecimentos astronmicos, a mdia ainda explora e muitas vezes desperta o interesse pela astronomia com assuntos que no fazem parte de nosso cotidiano como, por exemplo, o homem na Lua, os projetos espaciais e a primeira viagem de um astronauta brasileiro no espao. Porm, em certos casos, a mdia pode promover conhecimentos incompletos ou mesmo equivocados sobre os conceitos que envolvam a astronomia, como por exemplo a propagao do som no vcuo observado na maioria dos filmes de f ico cientfica ou da existncia das estaes do ano em funo da distncia da Terra ao Sol, em conformidade com o questionrio aplicado.

    Prior research reveals high unemployment rates among homeless youth. The literature offers many examples of using evidence-informed and evidence-based supported employment models with vulnerable populations to assist them in obtaining and maintaining employment and concurrently addressing mental health challenges. However, there are few examples to date of these models with homeless youth with mental illness. The purpose of this article was thus to describe a methodology for establishing a university-agency research partnership to design, implement, evaluate, and replicate evidence-informed and evidence-based interventions with homeless youth with mental illness to enhance their employment, mental health, and functional outcomes. Data from two studies are used to illustrate the relationship between vocational skill-building/employment and mental health among homeless youth. The article concludes with a discussion of the implications of conducting community-based participatory employment and clinical intervention research. The author highlights the opportunities and tensions associated with this approach. PMID:24294127

    A dráguló olajár „felszínre hozta a fosszilis energiahordozók környezetbarát energiahordozókkal való kiváltásának problémáját. Az olajkészletek korlátozottsága mellett a bizonytalan kitermelés és a folyamatosan növekvő árak a bioüzemanyagok felé irányítják a politikai döntéshozók és a befektetők figyelmét. Az olajimportőr országoknak a bioüzemanyag-gyártás nyersanyagainak hazai termelése lehetővé teszi importköltségeik visszafogását, az üvegházhatást okozó gázok kibocsátásának csökkentését, valamint a mezőgazdasági termelők jövedelem-színvonalának javítását.

    A search of variable stars was carried out, using a new software specifically created by the author, on a series of images acquired at the Astronomical Observatory of Santa Lucia di Stroncone (Terni, Italy) between October 2010 and March 2012. This research, named Fast Variable Stars Survey (FVSS), arose from the idea to verify if the log files pr oduced by the software Astrometrica (H. Raab), could be used as a basis for rapid detection of short-period variable stars. The r esults obtained showed that the idea is very valid, so that the new software has allowed the identification and the correct determination of the period of thirty-two new variable stars in the six stellar fields subjected to analysis.

    Quarternary lithium-ion battery electrolyte solutions containing ester co-solvents in mixtures of carbonates have been demonstrated to have high conductivity at low temperatures (< -20C). However, in some cases the presence of such co-solvents does not directly translate into improved low temperature cell performance, presumably due to the formation of ionically resistive surface films on carbonaceous anodes. In order to understand this behavior, a number of lithium-graphite cells have been studied containing electrolytes with various ester co-solvents, including methyl acetate (MA), ethyl acetate (EA), ethyl propionate (EP), and ethyl butyrate (EB). The charge/discharge characterization of these cells indicates that the higher molecular weight esters result in electrolytes which possess superior low temperature performance in contrast to the lower molecular weight ester-containing solutions, even though these solutions display lower conductivity values.

    A investigao do campo de flutuaes da Radiao Csmica de Fundo (RCF) pode oferecer um importante teste para os modelos cosmolgicos que descrevem a origem e a evoluo das flutuaes primordiais. De um lado, apresenta-se o modelo inflacionrio que prev um espectro de flutuaes adiabticas distribudas segundo uma gaussiana e, de outro, os modelos de defeitos topolgicos (dentre outros) que descrevem um mecanismo para a gerao de flutuaes de isocurvatura que obedecem a uma distribuio no gaussiana. Este trabalho tem como objetivo caracterizar traos do modelo no gaussiano de campo misto (entre flutuaes adiabticas e de isocurvatura) nos mapas do Wilkinson Microwave Anisotropy Probe (WMAP). Simulaes das anisotropias da RCF no contexto de mistura indicam traos marcantes na distribuio das flutuaes de temperatura, mesmo quando consideradas pequenas contribuies do campo de isocurvatura (da ordem de 0.001). O efeito da mistura entre os campos resulta na transferncia de potncia de flutuaes em escalas angulares intermedirias para flutuaes em pequenas escalas angulares. Este efeito pode ser caracterizado pela relao entre as amplitudes dos primeiros picos acsticos no espectro de potncia da RCF. Neste trabalho, investigamos a contribuio do campo de isocurvatura, no contexto de mistura, sobre as observaes recentes da RCF realizadas pelo WMAP. As previses do modelo de campo misto, uma vez confrontadas com as observaes em pequenas escalas angulares, podem ajudar a revelar a natureza das flutuaes primordiais.

    Autosomal-recessive cerebellar ataxias comprise a clinically and genetically heterogeneous group of neurodegenerative disorders. In contrast to their dominant counterparts, unraveling the molecular background of these ataxias has proven to be more complicated and the currently known mutations provide incomplete coverage for genotyping of patients. By combining SNP array-based linkage analysis and targeted resequencing of relevant sequences in the linkage interval

    Actinide dioxides derived from the AnO{sub 2} fluorite lattice are of high technological relevance due to their application in nuclear reactor fuels. Oxidation of AnO{sub 2} compounds emerges as a central theme in fuel fabrication, reactor operation, long-term storage forms for both spent fuels and surplus weapons materials, and environmental actinide migration. In this paper, we use density functional theory calculations to study the oxidation of uranium, neptunium and plutonium dioxides, AnO{sub 2} (An = U, Np or Pu), in O{sub 2} and O{sub 2}/H{sub 2}O environments. We pay particular attention to the formation of oxygen clusters (co-operativity) in AnO{sub 2+x} and how this phenomenon govern oxidation thermodynamics and the development of ordered An{sub 4}O{sub 9} compounds. The so-called split di-interstitial, which is composed of two nearest neighbor octahedral oxygen interstitials that are distorted in such a way that they dislocate one regular fluorite lattice oxygen ion to form a cluster of triangular geometry, is predicted to be the fundamental building block of the most stable cluster configurations. We also identify how the formation of oxygen defect clusters and the degree of oxidation in AnO{sub 2+x} are both governed by the characer of the An-5f to excess O-2p charger transfer, i.e. the charge transfer to the O-2p orbitals of the interstitial-like (+x) ions, and the ability of the excess O-2p orbitals to hybridize with regular fluorite lattice ions.

    Gradientes radiais de abundncia so observados no disco de nossa Galxia e tambm em outras galxias espirais. No caso da Galxia, o principal problema relativo aos gradientes sua variao temporal, que constitui um dos principais vnculos aos modelos de evoluo qumica da Galxia. As nebulosas planetrias so particularmente interessantes no estudo dos gradientes e suas variaes, tanto espaciais como temporais. So objetos brilhantes, podendo ser observadas a grandes distncias, e tm abundncias relativamente precisas de diversos elementos qumicos. Alm disso, sendo originadas de estrelas com massas entre 0.8 e 8 massas solares na sequncia principal, incluem objetos com idades e populaes diferentes, o que as torna especialmente interessantes ao estudo da variao temporal dos gradientes. Neste trabalho, apresentamos resultados recentes sobre a variao temporal do gradiente de O/H a partir de uma amostra contendo cerca de 200 nebulosas, para as quais obtivemos distncias por mtodos estatsticos. As abundncias foram parcialmente obtidas a partir de observaes em Itajub e La Silla, sendo as restantes obtidas da literatura. Os resultados mostram, pela primeira vez, evidncias de um achatamento do gradiente de O/H, de -0.11 dex/kpc para -0.06 dex/kpc nos ltimos 9 giga-anos ou de -0.08 dex/kpc para -0.06 dex/kpc nos ltimos 5 giga-anos. Esses valores apresentam um bom acordo com alguns modelos recentes para a evoluo qumica da Galxia. (FAPESP/CNPq)

    amplamente reconhecido que as pessoas em geral tm grande fascnio e interesse pela Astronomia. Por outro lado, o contedo dessa rea includo no ensino formal est longe de ser abrangente e suficiente para suprir a demanda. Esse interesse permite aperfeioar a divulgao e o ensino no formal de Astronomia atravs da mdia aliando a adequao do contedo expectativa das pessoas. A reforma do Currculo Bsico da Escola Pblica da maioria dos Estados brasileiros tem introduzido Astronomia desde a pr-escola at o Ensino Mdio. Num estudo realizado com 1180 alunos do Ensino Mdio de seis escolas estaduais, revelou-se atravs da aplicao de um formulrio contendo questes que abordavam conhecimentos bsicos em Astronomia, como foram adquiridos tais conhecimentos e infra-estrutura da escola. Para 66,1% dos entrevistados o professor j fez alguma apresentao a respeito de Astronomia. O presente estudo revelou tambm que 54,4% dos alunos entrevistados adquiriram seus conhecimentos astronmicos na escola, 18,4% atravs da televiso e 27,1% afirmaram que seus conhecimentos foram obtidos atravs de outros tipos de mdia (internet, livros didticos, filmes e revistas). Embora o estudo revele claramente que h certo equilbrio no meio em que os alunos obtiveram seus conhecimentos astronmicos, a mdia busca no somente sua difuso, mas a disponibilizao desse conhecimento de maneira correta, que s vezes, no atingido, apresentando conceitos sem fundamentao e incorretos. Por outro lado, no dia-a-dia escolar, comum encontrar professores que vm para as aulas com concepes prvias, que podem diferir substancialmente das idias a serem ensinadas, dificultando o aprendizado de futuros conceitos cientficos. Uma avaliao criteriosa, avaliando as dificuldades dos professores em determinar o sentido correto dos conceitos e observando a metodologia que utilizam no ensino, poder proporcionar uma melhor compreenso sobre as concepes alternativas, presentes no ensino de Astronomia.

    Solid electrolyte interphase (SEI) is an in situ formed thin coating on lithium ion battery (LIB) electrodes. The mechanical property of SEI largely defines the cycling performance and the safety of LIBs but has been rarely investigated. Here, we report quantitatively the Young's modulus of SEI films on MnO anodes. The inhomogeneity of SEI film in morphology, structure, and mechanical properties provides new insights to the evolution of SEI on electrodes. Furthermore, the quantitative methodology established in this study opens a new approach to direct investigation of SEI properties in various electrode materials systems. PMID:22385103

    O presente trabalho prope-se a resgatar uma experincia que teve lugar no Planetrio de So Paulo nos anos 60. Em 1962, o Sr. Accio, ento com 37 anos, deficiente visual desde os 27, passou a assistir s aulas ministradas pelo Prof. Aristteles Orsini aos integrantes do corpo de servidores do Planetrio. O Sr. Accio era o nico deficiente da turma e, embora possusse conhecimentos bsicos e relativamente avanados de matemtica, enfrentava dificuldades na compreenso e acompanhamento da exposio, como tambm em estudos posteriores. Com o intuito de auxili-lo na superao desses problemas, o Prof. Orsini solicitou a construo de modelos mecnicos que, atravs do sentido do tato, permitissem o acompanhamento das aulas e a transposio do modelo para o "constructo" mental. Essa prtica mostrou-se to eficaz que facilitou sobejamente o aprendizado da matria pelo sujeito. O Sr. Accio passou a integrar o corpo de professores do Planetrio/Escola Municipal de Astrofsica, tendo ficado responsvel pelo curso de "Introduo Astronomia" por vrios anos. Alm disso, a experincia foi to bem sucedida que alguns dos modelos tiveram seus elementos constitutivos pintados diferencialmente para serem utilizados em cursos regulares do Planetrio, tornando-se parte integrante do conjunto de recursos didticos da instituio. pensando nessa eficcia, tanto em seu objetivo original permitir o aprendizado de um deficiente visual quanto no subsidirio recurso didtico sistemtico da instituio que decidimos resgatar essa experincia. Estribados nela, acreditamos ser extremamente produtivo, em termos educacionais, o aperfeioamento dos modelos originais, agora resgatados e restaurados, e a criao de outros que pudessem ser utilizados no ensino dessa cincia a deficientes visuais.

    A luz das estrelas foi, historicamente, vista por observadores de AGNs como uma poluio inconveniente. Conseqentemente, a informao contida nas caractersticas estelares foi, durante muito tempo, largamente omitida. Nos primeiros estudos, o mtodo empregado para remover esta contaminao estelar foi represent-la por um template de galxia elptica e subtra-la do espectro observado, restando o puro AGN como um resduo. Hoje sabemos que no to simples representar essa populao. Vrios estudos tm mostrado a presena de formao estelar recente prxima a regio nuclear de galxias Seyfert. Neste trabalho foi revisada a abordagem tradicional, tendo-se focalizado a anlise na luz estelar. Espectros ticos de fenda longa, com alta razo sinal/rudo, foram usados para estudar a variao radial das larguras equivalentes de linhas de absoro e cores do contnuo. Utilizando o mtodo de sntese espectral de populaes estelares, foram estimadas as contribuies de populaes estelares de diferentes idades (e de um contnuo tipo lei de potncia) para a luz integrada das galxias, em 4020A. As principais concluses deste trabalho so: na regio nuclear, mais da metade das galxias Seyfert 2 da amostra (57%) apresenta contribuies das populaes com 100 milhes de anos ou mais jovens superior a 20% do fluxo em 4020A, enquanto que em cerca de 40% delas a componente de 3 milhes de anos (e/ou luz que provem de um ncleo ativo) tem contribuio significativa (maior do que 10%). Estas contribuies em geral decrescem quando se vai para regies mais distantes do centro das galxias, respectivamente 53% e 30% a 1kpc, 40% e 15% a 3kpc do centro das galxias. Estes resultados foram comparados com aqueles obtidos para uma amostra de galxias no ativas de mesmo tipo de Hubble das Seyfert. Em uma anlise inicial nota-se que em geral as galxias Seyfert apresentam contribuies das populaes de 100 milhes de anos maiores do que aquelas encontradas nas galxias no ativas, sugerindo uma ligao entre a formao estelar e a atividade em galxias.

    OBJECTIVE To analyze the prevalence and factors associated with smoking abstinence among patients who were treated in a reference unit for smoking cessation. METHODS This cross-sectional study examined the medical records of 532 patients treated in a reference unit for smoking cessation in Belm, PA, Northern Brazil, between January 2010 and June 2012. Sociodemographic variables and those related to smoking history and treatment were analyzed. Statistical significance was set at p < 0.05. RESULTS The mean age of the participants was 50 years; 57.0% of the patients were women. The mean tobacco load was 30 packs/year, and the mean smoking duration was approximately 32 years. Most patients remained in treatment for four months. The rate of smoking abstinence was 75.0%. Regression analysis indicated that maintenance therapy, absence of relapse triggers, and lower chemical dependence were significantly associated with smoking cessation. CONCLUSIONS The smoking abstinence rate observed was 75.0%. The cessation process was associated with several aspects, including the degree of chemical dependence, symptoms of withdrawal, and period of patient follow-up in a multidisciplinary treatment program. Studies of this nature contribute to the collection of consistent epidemiological data and are essential for the implementation of effective smoking prevention and cessation strategies.OBJETIVO Analisar a prevalncia e fatores associados abstinncia tabgica entre pacientes atendidos em unidade de referncia para cessao do tabagismo.

    Tem sido prtica comum nos ltimos anos estudar a distribuio de luminosidade em galxias fazendo uso da informao contida em toda a imagem da galxia, j que esta tcnica tem se mostrado muito mais confivel do que o simples ajuste de perfis radiais de luminosidade. Atravs destes estudos bidimensionais, melhores resultados tem sido obtidos na anlise e.g. do Plano Fundamental, de correlaes entre os parmetros estruturais de galxias, de sub-estruturas como barras e anis nucleares etc. Apresentamos um novo cdigo bidimensional, o BUDDA, de anlise estrutural de galxias, que ser disponibilizado para a comunidade. Desenvolvido por ns, o cdigo determina os parmetros estruturais de galxias de forma prtica e robusta, e pode ser aplicado genericamente em qualquer estudo sobre a formao, evoluo e estrutura de galxias. O programa ainda permite a avaliao direta de sub-estruturas, atravs de imagens residuais que so obtidas ao se subtrair, das imagens originais, bojo e disco sintticos que melhor representam essas componentes da galxia sob considerao. Ser apresentada a forma de utilizao do cdigo, bem como sries de testes que atestam a sua funcionalidade. Alm disso, os resultados da aplicao do cdigo em uma amostra de 51 galxias sero expostos como exemplo prtico, e do seu enorme potencial de uso.

    Atualmente vivencia-se um mundo globalizado onde os computadores e a internet permitiram um acesso rpido e seguro a todo tipo de informao e conhecimento. O presente trabalho visa analisar a maneira pela qual alunos de segundo grau da rede estadual da cidade de So Paulo obtiveram, caso tenham, conhecimentos bsicos de astronomia quanto aos fenmenos celestes que os rodeiam, tais como a sucesso dos dias e das estaes do ano, alm de question~los sobre fatos genricos tais como: o que vem a ser o Sol, o Big Bang, o que ocasionou a extino dos dinossauros. Para tanto foi elaborado um formulrio constando de questes de mltipla escolha, o qual foi aplicado no primeiro colegial diurno da Escola Estadual Guilherme de Almeida. Num espao amostral de 44 alunos constatou-se que 41% dos alunos adquiriram seus conhecimentos astronmicos na escola e 59% atravs da mdia em geral. Neste mesmo espao amostral apenas 11% dos alunos usaram computadores na escola, 41% na residncia, 5% no trabalho e 43% no utilizaram. O presente estudo revelou tambm que para 50% dos alunos o professor jamais utilizou um programa de computador a respeito de astronomia ou fez alguma apresentao sobre o tema. Embora em sua fase inicial este estudo revela claramente que a maioria dos alunos no obtm na escola seus conhecimentos astronmicos, estes provm de fontes no especificamente didtico-pedaggicas tais como filmes e revistas populares que no raramente geram conhecimentos incompletos e em muitos casos inclusive falhos.

    The calcium-activated chloride channel anoctamin1 (ANO1; TMEM16A) is fundamental for the function of epithelial organs. Mice lacking ANO1 expression exhibit transport defects and a pathology similar to cystic fibrosis. They also show a general defect of epithelial electrolyte transport. Here we analyzed expression of all ten members (ANO1ANO10) in a broad range of murine tissues and detected predominant expression of ANO1, 6, 7, 8, 9, 10 in epithelial tissues, while ANO2, 3, 4, 5 are common in neuronal and muscle tissues. When expressed in Fisher Rat Thyroid (FTR) cells, all ANO proteins localized to the plasma membrane but only ANO1, 2, 6, and 7 produced Ca2+-activated Cl? conductance, as analyzed by ATP-induced iodide quenching of YFP fluorescence. In contrast ANO9 and ANO10 suppressed baseline Cl? conductance and coexpression of ANO9 with ANO1 inhibited ANO1 activity. Patch clamping of ANO-expressing FRT cells indicated that apart from ANO1 also ANO6 and 10 produced chloride currents, albeit with very different Ca2+ sensitivity and activation time. We conclude that each tissue expresses a set of anoctamins that form cell- and tissue-specific Ca2+-dependent Cl? channels. PMID:20056604

    A natureza do contnuo UV/tico em rdio-galxias muito importante para o seu entendimento. Em baixos redshifts existem evidncias de que muitas delas so dominadas no tico por luz de estrelas velhas, caractersticas de galxias early-type e em altos redshifts a caracterstica dominante um excesso de luz no UV, freqentemente associado com estruturas que esto alinhadas aos eixos das estruturas rdio em grande escala. Inicialmente esse excesso foi interpretado como devido a episdios intensos de formao estelar nas galxias hospedeiras. Entretanto, as descobertas dos alinhamentos entre as estruturas UV e rdio modificaram essa idia. Foi proposto que a formao estelar iniciada pela passagem do jato rdio atravs do meio interestelar das galxias hospedeiras. A natureza do excesso UV comeou a ser compreendida em um estudo detalhado do continuo tico da 3C321, onde se concluiu que o contnuo desta galxia tem origem multicomponente, com contribuies de populaes velhas e intermedirias, de luz espalhada oriunda de um quasar obscurecido e do contnuo nebular. No presente trabalho estudamos a populao nuclear e extranuclear de uma amostra de 24 rdio-galxias, utilizando espectros ticos de fenda longa, com alta razo sinal/rudo. Atravs do mtodo de sntese espectral de populaes estelares, foram estimadas as contribuies de populaes estelares de diferentes idades (e de um contnuo tipo lei de potncia devido a um AGN, FC) para a luz integrada das galxias, em 4020. As principais concluses deste trabalho so: apenas quatro dos objetos estudados tm contribuies significativas (maiores do que 10%) das populaes de 100 milhes de anos ou mais jovens (ou de FC) ao longo da regio espacial estudada (6 kpc centrais); nenhuma das rdio-galxias de tipo FRI estudadas tem contribuio significativa destas populaes ao longo desta regio; duas (de oito) de tipo FRII tem contribuies significativas da luz que vem do AGN, na regio nuclear; uma tem contribuio significativa das populaes de 100 milhes de anos e mais jovens ao longo dos 4 kpc centrais, indicando claramente a presena de formao estelar recente. Comparando estes resultados com aqueles obtidos para uma amostra de galxias no ativas de mesmo tipo de Hubble das rdio, encontramos que a principal diferena entre as duas amostras est na contribuio da populao de 1 bilho de anos, geralmente maior nas rdio-galxias.

  1. Highly Quantitative Electrochemical Characterization of Non-Aqueous Electrolytes & Solid Electrolyte Interphases

    The methods to measure solid electrolyte interphase (SEI) electrochemical properties and SEI formation capability of non-aqueous electrolyte solutions are not adequately addressed in the literature. And yet, there is a strong demand in new electrolyte generations that promote stabilized SEIs and have an influence to resolve safety, calendar life and other limitations of Li-ion batteries. To fill this gap, in situ electrochemical approach with new descriptive criteria for highly quantitative characterization of SEI and electrolytes is proposed. These criteria are: SEI formation capacity, SEI corrosion rate, SEI maintenance rate, and SEI kinetic stability. These criteria are associated with battery parameters like irreversible capacity, self-discharge, shelf-life, power, etc. Therefore, they are especially useful for electrolyte development and standard fast screening, allowing a skillful approach to narrow down the search for the best electrolyte. The characterization protocol also allows retrieving information on interfacial resistance for SEI layers and the electrochemical window of electrolytes, the other important metrics of characterization. The method validation was done on electrolyte blends containing phosphazenes, developed at Idaho National Laboratory, as 1.2M LiPF6 [80 % EC-MEC (2:8) (v/v) + 20% Phosphazene variety] (v/v), which were targeted for safer electrolyte variations.

    We investigated eating- and weight-related correlates of self-evaluation influences (SEIs) and examined the extent to which such SEIs can be both over- and undervalued and the extent to which measurement strategy affects SEIs. A female undergraduate sample (n = 549) completed 3 measures of SEI importance and questionnaires assessing disordered eating (DE), body mass index (BMI), and depression. SEI measures included Likert scale, rank ordering, and pairwise forced choice; a subset (n = 62) also completed the Shape- and Weight-Based Self-Esteem Scale (SAWBS). Only rank ordering, forced choice, and SAWBS constrain choices among SEIs, such that prioritizing one SEI necessarily deprioritizes another, which reflects real-world restrictions on individuals' allotment of time and energy (e.g., spending hours exercising daily necessarily reduces time available for other activities). By any measure, women with DE overvalue body shape and weight. The constraining measures reveal systematic undervaluation of intelligence and achievement among women with DE and an enhanced effect of DE on the overvaluation of weight and on the undervaluation of being a good person among those with higher BMI. Depressed women's self-evaluations overemphasize appearance and underemphasize interpersonal relationships. Self-evaluations of women with DE are marked by both over- and undervaluation of relevant SEIs; the overvaluation of shape and weight in DE may be associated with costs. Future use of constraining measures, such as forced choice or rank ordering, may enhance our understanding of both over- and underemphasized SEIs among women with DE. PMID:24854805

    Systems Engineering and Integration (SE&I) is a critical discipline in developing new space systems. In 2005, NASA performed an internal study of 24 agency and Department of Defense (DoD) programs to evaluate methods of integrating SE&I practices and determine their effectiveness. The goal of the study was to determine the best SE&I implementation strategy for the Ares Projects Office. The study identified six SE&I organizational structures: 1. Lead systems integrator (LSI) with SE&I responsibility and government technical insight. 2a. Integration contractor with government SE&I responsibility (government insight). 2b. Integration contractor with government SE&I responsibility (government oversight). 3a. Prime contractor with SE&I responsibility (government insight). 3b. Prime contractor with SE&I responsibility (government oversight). 3c. Prime contractor with SE&I responsibility (government/industry partnership). 4a.Prime contractor with government SE&I responsibility (government insight). 4b. Prime contractor with government SE&I responsibility (government oversight). 4d.Prime contractors with total system performance responsibility (TSPR). 5. Prime contractor with government SE&I responsibility and integration products through a Federally Funded Research and Development Center (FFRDC). 6. Government/FFRDC in-house development with SE&I responsibility and function. The organizational structure used most often was number 4, using a prime contractor with government SE&I responsibility and government technical insight. However, data analyses did not establish a positive relationship between program development costs and specific SE&I organizational types, nor did it positively determine the relationship between successful programs or projects and their SE&I structure. The SE&I study reached the following conclusions: (1) Large, long-duration, technically complex programs or projects reach their technical goals, but rarely meet schedule or cost goals. NASA's recent successes have been smaller, short-duration development projects using heritage hardware/software, focused technology development, technical oversight and stable external factors. (2) Programs and projects have failed or been terminated due to lack of technical insight, relaxing of SE&I processes, and unstable external factors. (3) The study did not find a single, clear optimum SE&I organization type to fit all projects. However, while any organizational structure can be made to work, the fewer complexities in the program, the better the likelihood of success. (4) The most common successful SE&I organization structure type in the study was type 4b, where the government maintained integration responsibility, with the prime contractor providing SE&I products and the government providing technical oversight. This study was instrumental in helping the APO select organization structure 4, following the same SE&I and oversight process used during humanlund7s last voyages to the Moon.

    Anoctamin 6 (ANO6), also known as TMEM16F, has been shown to be a calcium-activated anion channel with delayed calcium activation. The cellular function of ANO6 is under debate, and different groups have come to different conclusions about ANO6's physiological role. Although it is now quite well established that ANO6 is distinct from the volume-regulated anion channel, it is still unclear whether ANO6 or other anoctamins can be activated by cell swelling. In this study, we suggest that ANO1, ANO6, and ANO10 do not contribute to the volume-activated current in ANO-overexpressing HEK293 cells. Furthermore, knock-down of ANO6 in Ehrlich ascites tumor cells (EATC) and Ehrlich-Lettre ascites (ELA) did not decrease but instead significantly increased swelling-activated membrane currents. Knock-down of ANO6 in EATC did not reduce regulatory volume decrease (RVD) in the absence of extracellular calcium, whereas it significantly reduced RVD in the presence of calcium. Interestingly, we found that knock-down of ANO6 in ELA cells resulted in a decrease in cisplatin-induced caspase-3 activity, confirming earlier findings that ANO6 is involved in apoptosis. Finally, knock-down of ANO1 and ANO6 did not affect the volume-sensitive release of taurine in ELA cells. Thus, our data provide evidence that ANO6 cannot be activated directly by cell swelling unless Ca(2+) is present. We also conclude that ANO6 carries a current during RVD, provided extracellular calcium is present. Thus, swelling activation of ANO6 requires the presence of free calcium. PMID:24419539

    OBJECTIVE To analyze the coverage of a cervical cancer screening program in a city with a high incidence of the disease in addition to the factors associated with non-adherence to the current preventive program. METHODS A cross-sectional study based on household surveys was conducted. The sample was composed of women between 25 and 59 years of age of the city of Boa Vista, RR, Northern Brazil who were covered by the cervical cancer screening program. The cluster sampling method was used. The dependent variable was participation in a women's health program, defined as undergoing at least one Pap smear in the 36 months prior to the interview; the explanatory variables were extracted from individual data. A generalized linear model was used. RESULTS 603 women were analyzed, with an mean age of 38.2 years (SD = 10.2). Five hundred and seventeen women underwent the screening test, and the prevalence of adherence in the last three years was up to 85.7% (95%CI 82.5;88.5). A high per capita household income and recent medical consultation were associated with the lower rate of not being tested in multivariate analysis. Disease ignorance, causes, and prevention methods were correlated with chances of non-adherence to the screening system; 20.0% of the women were reported to have undergone opportunistic and non-routine screening. CONCLUSIONS The informed level of coverage is high, exceeding the level recommended for the control of cervical cancer. The preventive program appears to be opportunistic in nature, particularly for the most vulnerable women (with low income and little information on the disease). Studies on the diagnostic quality of cervicovaginal cytology and therapeutic schedules for positive cases are necessary for understanding the barriers to the control of cervical cancer.OBJETIVO Analisar a cobertura do programa de rastreamento do cncer do colo uterino em municpio com alta incidncia da doena e os fatores relacionados no adeso ao programa preventivo vigente.

    Oxidative damage and apoptosis are critical factors contributing to neuronal death during a stroke. The aim of the present study was to evaluate the neuroprotective effects of senkyunolide I (SEI) on focal cerebral ischemia-reperfusion (I/R) injury in rats, and investigate the underlying mechanisms. Male Sprague-Dawley rats were subjected to transient middle cerebral artery occlusion (tMCAO) for 2h, followed by 24h reperfusion, and then randomly assigned into four groups: Sham (sham-operated), Vehicle (tMCAO +normal saline), SEI-L (tMCAO +SEI 36mg/kg) and SEI-H (tMCAO +SEI 72mg/kg) groups. SEI was administered intravenously, 15min after occlusion. Neurological deficit, brain edema and infarct volume were detected after 24h of reperfusion. Histological structures of cortices and hippocampus were observed by hematoxylin and eosin staining. Biochemical indexes in the cortex were assayed by colorimetry. The impact of SEI on the Nrf2-ARE-interaction was assayed using a luciferase reporter gene. Western blotting was performed to analysis the expressions of proteins related to anti-oxidation and apoptosis. SEI administration significantly ameliorated the neurological deficit, reduced the infarct volume and brain edema, reversed the cerebral morphologic damage, decreased the levels of MDA and increased the activities of superoxide dismutase. Furthermore, the high dose SEI could significantly activate the Nrf2/ARE pathway by up-regulating the phosphorylation of Erk1/2 and inducing Nrf2 nuclear translocation with enhanced HO-1 and NQO1 expressions. Additionally, treatment with SEI remarkably promoted the ratio of Bcl-2/Bax and inhibited the expressions of cleaved caspase 3 and caspase 9. These results suggest that the neuroprotective mechanisms of SEI are associated with its anti-oxidation and anti-apoptosis properties. PMID:25698615

  10. Role of surface oxides in the formation of solid-electrolyte interphases at silicon electrodes for lithium-ion batteries.

    Nonaqueous solvents in modern battery technologies undergo electroreduction at negative electrodes, leading to the formation of a solid-electrolyte interphase (SEI). The mechanisms and reactions leading to a stable SEI on silicon electrodes in lithium-ion batteries are still poorly understood. This lack of understanding inhibits the rational design of electrolyte additives, active material coatings, and the prediction of Li-ion battery life in general. We prepared SEI with a common nonaqueous solvent (LiPF6 in PC and in EC/DEC 1:1 by wt %) on silicon oxide and etched silicon (001) surfaces in various states of lithiation to understand the role of surface chemistry on the SEI formation mechanism and SEI structure. Anhydrous and anoxic techniques were used to prevent air and moisture contamination of prepared SEI films, allowing for more accurate characterization of SEI chemical stratification and composition by X-ray photoelectron spectroscopy (XPS) and time-of-flight secondary ion mass spectrometry (TOF-SIMS) depth profiling. Additionally, multivariate statistical methods were used to better understand TOF-SIMS depth profiling studies. We conclude that the absence of native-oxide layer on silicon has a significant impact on the formation, composition, structure, and thickness of the SEI. PMID:25402271

  2. Surface properties of fluoroethylene carbonate-derived solid electrolyte interface on graphite negative electrode by narrow-range cycling in cell formation process

    2014-12-01

    A modified solid electrolyte interface (SEI) on a graphite negative electrode with a fluoroethylene carbonate (FEC) additive was prepared by narrow-range cycling in a cell formation process. The SEI surface properties were investigated by extreme high-resolution scanning electron microscopy (XHR-SEM) under low acceleration voltage and X-ray photoelectron spectroscopy (XPS). A linkage structure of submicron-sized particles on the SEI film layer largely developed by narrow-range cycling in the formation process; these particles were mainly composed of the inorganic component (Psbnd F bonding states, LiPxOyFz) from the FEC. The application of narrow-range cycling with an FEC additive in the formation process improves the cycling performance and Coulombic efficiency of the cell. It is suggested that the SEI layer modified with FEC-derived SEI components on the graphite anode electrode by narrow-range cycling in the formation process, could improve the cell performance.

    Chen, Chien-Fan; Mukherjee, Partha P

    2015-04-01

    Solid electrolyte interphase (SEI) formation, due to the electrochemical reaction between the salt and solvent in the electrolyte, is a key contributor to the electrode performance decay in lithium-ion batteries. The active particle morphology and electrode microstructure affect the side reaction rate and hence the SEI induced interfacial transport and impedance behavior. The change resistance due to the variation of SEI thickness can be inferred from electrochemical impedance spectroscopy. In this study, we proposed a microstructure-aware impedance model to predict the effect of electrode microstructure on impedance response. Our model successfully captures the influence of active particle morphology on the SEI formation and corresponding impedance characteristics. Different electrode realizations with microstructural and compositional variations have been considered. The critical influence of active material morphology, mean particle size, binder and electrolyte volume fractions on the SEI formation and impedance behavior reveals the underlying interdependences of the interfacial and transport resistance modes.

    The mass-reared colony of Anastrepha ludens (Loew) currently used in Mexico for suppression of the Mexican fruit fly has been in use for over 10 years. Sterile flies are released into a wide range of environmental conditions as part of an integrated area-wide approach to suppress diverse populations of this pest in the Mexican Republic. This paper assesses the performance of the sterile flies interacting with wild populations from the different environments. We investigated the sexual compatibility and competitiveness of the sterile flies when competing with wild populations from 6 representatives Mexican states: Nuevo Leon, Tamaulipas, Sinaloa, Nayarit, Michoacan, and Chiapas. Results show that the males of the wild populations differed in the time to the onset and peak of sexual activity. Nevertheless, the index of sexual isolation (ISI) reflected sexual compatibility between the populations and the mass-reared strain, indicating that the sterile individuals mate satisfactorily with the wild populations from the 6 states. The male relative performance index (MRPI) showed that the sterile male is as effective in copulating as the wild males. The female relative performance index (FRPI) reflected a general tendency for wild females to copulate in greater proportion than the sterile females, except for the strains from Tamaulipas and Chiapas. In general, the lower participation of the sterile females in copulation increases the possibilities of sterile males to mate with wild females. The relative sterility index (RSI) showed that the acceptance by wild females of the sterile males (25-55%) was similar to that of wild males. Females of the Chiapas strain showed the lowest acceptance of sterile males. Finally, the results obtained in the Fried test (which measures induced sterility in eggs) showed a competitiveness coefficient ranging from 0.2 to 0.5. This suggests that sterile males successfully compete and are compatible with flies from different geographic origins.

Los insectos esteriles son liberados en una gran variedad de condiciones ambientales como parte de un control integrado para suprimir diversas poblaciones de esta plaga dentro de la Republica Mexicana. El objetivo de este documento esta dirigido a revisar el desempeno de las moscas esteriles frente a poblaciones silvestres procedentes de diferentes ambientes y para esto se realizaron comparaciones de compatibilidad y competitividad sexual de las moscas esteriles contra poblaciones silvestres de seis estados representativos de la Republica Mexicana: Nuevo Leon, Tamaulipas, Sinaloa, Nayarit, Michoacan y Chiapas. Los resultados obtenidos manifiestan diferencias en el horario de inicio de llamado y mayor actividad sexual del macho entre las moscas provenientes de cada estado. Sin embargo el indice de aislamiento (ISI) reflejo compatibilidad sexual entre la cepa de laboratorio y todas las poblaciones analizadas, indicando que los individuos esteriles pueden aparearse satisfactoriamente con las poblaciones silvestres de los seis estados. El indice de efectividad de apareamiento del macho (MRPI) reflejo de manera global que los machos esteriles son tan efectivos para copular como los silvestres. El indice de efectividad de apareamiento de la hembra (FRPI) reflejo que en la mayoria de los estados las hembras silvestres copularon en mayor proporcion que las hembras esteriles, excepto para las poblaciones de Tamaulipas y Chiapas. En general, la baja participacion de las hembras esteriles en el campo permitio al macho esteril ampliar su probabilidad de apareamiento con las hembras silvestres. En cuanto al indice de esterilidad relativa (RSI), observamos que la aceptacion de las hembras silvestres al macho esteril (25-55%) fue similar a la de los machos silvestres.

    2014-04-01

    We have investigated the formation of the solid electrolyte interphase (SEI) on lithium electrodes in the presence of an ionic liquid electrolyte with a particular focus on the influence of polysulfides present in the electrolyte on the SEI. The electrochemical performance of symmetric cells with lithium electrodes and electrolytes composed of N-Methyl-(n-butyl)pyrrolidinium bis(trifluoromethanesulfonyl)imide (PYR14-TFSI) and LiTFSI, with and without the addition of polysulfides, were analyzed as well as the chemical composition of the SEI, before and after cycling. The cycling behavior of the symmetrical cells shows that the SEI films are relatively stable in the ionic liquid electrolyte, also in the presence of polysulfides. However, the presence of polysulfides results in a higher SEI layer resistance (RSEI) and a higher activation energy. From X-ray photoelectron spectroscopy spectra (XPS), with argon-ion sputtering for depth profiling, we find that the SEI is formed by decomposition products from both cations and anions of the electrolyte. The XPS spectra show that the presence of polysulfides alters the decomposition process of the electrolyte, resulting in a SEI film with different chemical composition and structure, in line with the results from the electrochemical performance.

    The phytotoxins seiridin (SEI) and iso-seiridin (ISE), two delta alpha,beta-butenolides produced in vitro by Seiridium cardinale, S. cupressi, and S. unicorne, as well as their derivatives obtained by chemical modification of each toxin, were analyzed for their bioactivity. The effects each compound on host and non-host plants and their antimicrobial activity on bacteria were investigated. The toxicity of both seiridins (SEIs) decreased in the derivatives with modifications of the gamma-lactone ring or with acetylation of the hydroxy group of the aliphatic side chain at C-4. Shoot tissues of Cupressus macrocarpa artificially infected by S. cardinale leached electrolytes more than those of C. sempervirens and C. arizonica. Electrolyte loss from shoot tissues of cypress plants treated with each derivative also decreased for most of them. Seed germination was not affected by SEI and ISE derivatives. Inhibition of root growth of three herbaceous test plants was studied. SEI and 3,4-dihydro SEI were active to germlings of lettuce. No ISE derivative affected root growth of lettuce and oat germlings. Reduction was observed on roots of radish germlings treated with acetyl ISE or 3,4-dihydro ISE. No derivative of SEI or ISE elicited hormone-like activity as SEI did. Antibacterial activity shown by SEI and ISE at 150 microM accounted for both hydrogenated derivatives of SEI. The integrity of the delta alpha,beta-unsaturated-gamma-lactone ring and the location of the hydroxy group in the heptyl side chain are features of importance in biological activity of the two butenolides.

    The SEIS instrument onboard the InSight mission to Mars is the critical instrument for determining the interior structure of Mars and for determining the current level of tectonic activity and the meteorite flux. Meeting the performance requirements of the SEIS instrument is vital to successfully achieve these mission objectives. However, there has never been a complete study taking into account all of the potential noise sources on seismometers in the Martian environment. Here we attempt to understand and evaluate the noise contributions due to the Martian environment and determine the cumulative effect that these are likely to have on the SEIS instruments.

    A trajetria evolutiva das estrelas de alta massa depende fortemente de suas taxas de perda de massa. Apesar do rpido progresso no estudo destas estrelas, a taxa de perda de massa e outros parmetros fsicos bsicos, como a temperatura superficial e a velocidade terminal do vento ainda no esto bem determinados. Isto ocorre devido presena de ventos irregulares, rpidos e fortes ao redor destas estrelas, tornando a interpretao dos seus espectros uma tarefa difcil. Assim, a modelagem do vento e da fotosfera dessas estrelas est sendo cada vez mais usada para obter tais parmetros a partir dos espectros. O aumento da taxa de perda de massa durante a fase LBV (Variveis Luminosas Azuis), comparado com outros tipos de estrelas, tem sido atribudo a instabilidades do tipo S Doradus. Dispomos de uma base de dados espectroscpicos cobrindo 22 anos de observaes de AG Carinae, incluindo um ciclo S Doradus completo, com espectros CCD em alta resoluo na faixa ptica e infravermelha. Utilizamos o programa desenvolvido por Schmutz (1997) para uma anlise preliminar desse ciclo, obtendo a taxa de perda de massa a partir da linha do Ha. No existe uma correlao clara da taxa de perda de massa com mudanas da temperatura efetiva, do raio da estrela e do fluxo na banda V. A estrela atingiu seu mnimo fotomtrico (raio mnimo) em 1990 e o mximo fotomtrico (raio mximo) em 1995, enquanto que o fluxo mximo da linha do Ha ocorreu em 1996. Alm disso a taxa de perda de massa no segue esse ciclo, contrariamente s idias correntes.

    BACKGROUND AND PURPOSE The molecular identity of calcium-activated chloride channels (CaCCs) in vascular endothelial cells remains unknown. This study sought to identify whether anoctamin-1 (Ano1, also known as TMEM16A) functions as a CaCC and whether hypoxia alters the biophysical properties of Ano1 in mouse cardiac vascular endothelial cells (CVECs). EXPERIMENTAL APPROACH Western blot, quantitative real-time PCR, confocal imaging analysis and patch-clamp analysis combined with pharmacological approaches were used to determine whether Ano1 was expressed and functioned as CaCC in CVECs. KEY RESULTS Ano1 was expressed in CVECs. The biophysical properties of the current generated in the CVECs, including the Ca2+ and voltage dependence, outward rectification, anion selectivity and the pharmacological profile, are similar to those described for CaCCs. The density of ICl(Ca) detected in CVECs was significantly inhibited by T16Ainh-A01, an Ano1 inhibitor, and a pore-targeting, specific anti-Ano1 antibody, and was markedly decreased in Ano1 gene knockdown CVECs. The density of ICl(Ca) was significantly potentiated in CVECs exposed to hypoxia, and this hypoxia-induced increase in the density of ICl(Ca) was inhibited by T16Ainh-A01 or anti-Ano1 antibody. Hypoxia also increased the current density of ICl(Ca) in Ano1 gene knockdown CVECs. CONCLUSIONS AND IMPLICATIONS Ano1 formed CaCC in CVECs of neonatal mice. Hypoxia enhances Ano1-mediated ICl(Ca) density via increasing its expression, altering the ratio of its splicing variants, sensitivity to membrane voltage and to Ca2+. Ano1 may play a role in the pathophysiological processes during ischaemia in heart, and therefore, Ano1 might be a potential therapeutic target to prevent ischaemic damage. PMID:24758567

    Complex, electrochemically driven transport processes form the basis of electrochemical energy storage devices. The direct imaging of electrochemical processes at high spatial resolution and within their native liquid electrolyte would significantly enhance our understanding of device functionality, but has remained elusive. In this work we use a recently developed liquid cell for in situ electrochemical transmission electron microscopy to obtain insight into the electrolyte decomposition mechanisms and kinetics in lithium-ion (Li-ion) batteries by characterizing the dynamics of solid electrolyte interphase (SEI) formation and evolution. Here we are able to visualize the detailed structure of the SEI that forms locally at the electrode/electrolyte interface during lithium intercalation into natural graphite from an organic Li-ion battery electrolyte. We quantify the SEI growth kinetics and observe the dynamic self-healing nature of the SEI with changes in cell potential.

  19. Lithium Dinitramide as an Additive in Lithium Power Cells

    NASA Technical Reports Server (NTRS)

    Gorkovenko, Alexander A.

    2007-01-01

    Lithium dinitramide, LiN(NO2)2 has shown promise as an additive to nonaqueous electrolytes in rechargeable and non-rechargeable lithium-ion-based electrochemical power cells. Such non-aqueous electrolytes consist of lithium salts dissolved in mixtures of organic ethers, esters, carbonates, or acetals. The benefits of adding lithium dinitramide (which is also a lithium salt) include lower irreversible loss of capacity on the first charge/discharge cycle, higher cycle life, lower self-discharge, greater flexibility in selection of electrolyte solvents, and greater charge capacity. The need for a suitable electrolyte additive arises as follows: The metallic lithium in the anode of a lithium-ion-based power cell is so highly reactive that in addition to the desired main electrochemical reaction, it engages in side reactions that cause formation of resistive films and dendrites, which degrade performance as quantified in terms of charge capacity, cycle life, shelf life, first-cycle irreversible capacity loss, specific power, and specific energy. The incidence of side reactions can be reduced through the formation of a solid-electrolyte interface (SEI) a thin film that prevents direct contact between the lithium anode material and the electrolyte. Ideally, an SEI should chemically protect the anode and the electrolyte from each other while exhibiting high conductivity for lithium ions and little or no conductivity for electrons. A suitable additive can act as an SEI promoter. Heretofore, most SEI promotion was thought to derive from organic molecules in electrolyte solutions. In contrast, lithium dinitramide is inorganic. Dinitramide compounds are known as oxidizers in rocket-fuel chemistry and until now, were not known as SEI promoters in battery chemistry. Although the exact reason for the improvement afforded by the addition of lithium dinitramide is not clear, it has been hypothesized that lithium dinitramide competes with other electrolyte constituents to react with lithium on the surface of the anode to form a beneficial SEI. Apparently, nitrides and oxides that result from reduction of lithium dinitramide on the anode produce a thin, robust SEI different from the SEIs formed from organic SEI promoters. The SEI formed from lithium dinitramide is more electronically insulating than is the film formed in the presence of an otherwise identical electrolyte that does not include lithium dinitramide. SEI promotion with lithium dinitramide is useful in batteries with metallic lithium and lithium alloy anodes.

    Background The linkage between the socio-economic inequality and HIV outcomes was analysed using data from a population-based household survey that employed multistage-stratified sampling. The goal is to help refocus attention on how HIV is linked to inequalities. Methods A socio-economic index (SEI) score, derived using Multiple Correspondence Analysis of measures of ownership of durable assets, was used to generate three SEI groups: Low (poorest), Middle, and Upper (no so poor). Distribution of HIV outcomes (i.e. HIV prevalence, access to HIV/AIDS information, level of stigma towards HIV/AIDS, perceived HIV risk and sexual behaviour) across the SEI groups, and other background characteristics was assessed using weighted data. Univariate and multivariate logistic regression was used to assess the covariates of the HIV outcomes across the socio-economic groups. The study sample include 14,384 adults 15 years and older. Results More women (57.5%) than men (42.3%) were found in the poor SEI [P<0.001]. HIV prevalence was highest among the poor (20.8%) followed by those in the middle (15.9%) and those in the upper SEI (4.6%) [P<0.001]. It was also highest among women compared to men (19.7% versus 11.4% respectively) and among black Africans (20.2%) compared to other races [P<0.001]. Individuals in the upper SEI reported higher frequency of HIV testing (59.3%) compared to the low SEI (47.7%) [P< 0.001]. Only 20.5% of those in poor SEI had good access to HIV/AIDS information compared to 79.5% in the upper SEI (P<0.001). A higher percentage of the poor had a stigmatizing attitude towards HIV/AIDS (45.6%) compared to those in the upper SEI (34.8%) [P< 0.001]. There was a high personal HIV risk perception among the poor (40.0%) and it declined significantly to 10.9% in the upper SEI. Conclusions Our findings underline the disproportionate burden of HIV disease and HIV fear among the poor and vulnerable in South Africa. The poor are further disadvantaged by lack of access to HIV information and HIV/AIDS services such as testing for HIV infection. There is a compelling urgency for the national HIV/AIDS response to maximizing program focus for the poor particularly women. PMID:24180366
