    Sun-Earth Day is a well-coordinated series of programs, resources and events under a unique yearly theme highlighting the fundamentals of heliophysics research and missions. A menu of activities, conducted throughout the year, inspire and educate participants. Sun-Earth Day itself can vary in date, but usually is identified by a celebration on or near the spring equinox. Through the Sun-Earth Day framework we have been able to offer a series of coordinated events that promote and highlight the Sun, its connection to Earth and the other planets. Sun-Earth Day events are hosted by educators, museums, amateur astronomers and scientists and occur at schools, community groups, parks, planetaria and science centers around the globe. Sun-Earth Day raises the awareness and knowledge of formal and informal education audiences concerning space weather and heliophysics. By building on the success of Sun-Earth Day yearly celebrations, we seek to affect people of all backgrounds and ages with the wonders of heliophysics science, discovery, and exploration in ways that are both tangible and meaningful to their lives.

    The NASA Sun-Earth Connection Education forum annually promotes and event called Sun-Earth Day: a national celebration of the Sun, the space around the Earth (geospace), and how all of it affects life on our planet. For the past 3 years this event has provided a venue by which classrooms, museums, planetaria, and at NASA centers have had a sensational time sharing stories, images, and activities related to the Sun-Earth connections and the views o fthe Sun from Earth. Each year we select a different theme by which NASA Space Science can be further related to cross-curricular activities. Sun-Earth Day 2002, "Celebrate the Equinox", drew parallels between Native American Cultures and NASA's Sun-Earth Connection research via cultural stories, interviews, web links, activities and Native American participation. Sun-Earth Day 2003, "Live From the Aurora", shared the beauty of the Aurora through a variety of activities and stories related to perspectives of Northern Peoples. Sun-Earth Day 2004 will share the excitement of the transit of Venus through comparisons of Venus with Earth and Mars, calculations of the distances to nearby stars, and the use of transits to identify extra-solar planets. Finally, Sun-Earth Day 2005 will bring several of these themes together by turning our focus to the history and culture surrounding ancient observatories such as Chaco Canyon, Machu Picchu, and Chichen Itza.

    The NASA Sun-Earth Connection Education Forum (SECEF) annually promotes an event called Sun-Earth Day. For Sun-Earth Day 2005 SECEF has selected a theme called "Ancient Observatories: Timeless Knowledge. This year's Sun-Earth Day theme is your ticket to a fascinating journey through time as we explore centuries of sun watching by a great variety of cultures. From ancient solar motion tracking to modern solar activity monitoring the Sun has always occupied an important spot in mankind's quest to understand the Universe. Sun-Earth Day events usually are centered on the spring equinox around March 21, but this year there has already been a webcast from the San Francisco Exploratorium and the Native American ruins at Chaco Canyon, New Mexico on the day of winter solstice 2004. There will be another webcast on March 20 live from Chichen Itza, Mexico highlighting the solar alignment that makes a serpent appear on one of the ancient pyramids. The website http://sunearthday.nasa.gov has been developed to provide the necessary resources and opportunities for participation by scientists and educators in giving school or general public programs about Sun-Earth Day. The goal is to involve as much of the student population and the public in this event as possible and to help them understand the importance of the Sun for ancient and modern peoples. Through engaging activities available on the website, classrooms and museums can create their own event or participate in one of the opportunities we make available. Scientists, educators, amateur astronomers, and museums are invited to register on the website to receive a free packet of materials about Sun-Earth Day for use in making presentations or programs about the event. Past and future Sun-Earth Days will be discussed as well.

  4. Sun-Earth Day - Teaching Heliophysics Through Education Technology

    2010-01-01

    Sun-Earth Day (SED) is an Education and Outreach program supported by the U.S, National Aeronautics and Space Administration (NASA). The intent of the program is to teach students and the general public about Heliophysics (the science of the study of the Sun, how it varies, and how solar dynamics affect the rest of the solar system, especially the Earth). The program was begun ten years ago. Each year since that time a particular day has been designated as "Sun-Earth Day ,,. Usually the day of the spring equinox (March 20 or 21) is Sun-Earth Day, but other days have been used as well. Each year a theme is chosen relating to Heliophysics and events reflecting that theme are planned not only for Sun-Earth Day, but for the entire year. From the very beginning educational technology was emphasized in the events in order to effectively reach wide audiences with the SED message. The main approach has been to have a "webcast" related to each year's theme, often from a location that supports the theme as well. For example, a webcast took place from the Mayan pyramids at Chichen Itza, Mexico to highlight the theme of "Ancient Observatories, Timeless Knowledge". Webcasts were not the only technology employed, however. Many of the themes centered on the dynamic nature of the Sun and the effects that solar storms can have on interplanetary space and in our day-to-day life on Earth. Activities for tracking when solar storms happen and how they affect the Earth were developed and brought together in an educational package called Space Weather Action Centers. This project is explained in more detail in another presentation in this session being given by Norma Teresinha Oliveira Reis. Recent Sun-Earth Days have utilized "social networking" technologies to reach widespread groups on the internet. Podcasts, Vodcasts, Facebook, Twitter, and Second Life are the types of network technologies being employed now. The NASA Distance learning Network is another method for bringing Sun-Earth

    2004-12-01

    Over the past six years, the NASA Sun-Earth Connection Education Forum has sponsored and coordinated education public outreach events to highlight NASA Sun-Earth Connection research and discoveries. Our strategy involves using celestial phenomena, such as total solar eclipses and the Transit of Venus to celebrate Sun-Earth Day, a popular Education and Public Outreach international program. Sun-Earth Day also focuses attention on Equinoxes and Solstices to engage K-12 schools and the general public in space science activities, demonstrations, and interactions with space scientists. In collaboration with partners that include the Exploratorium, Maryland Science Center, NASA Connect, Sun-Earth Connection missions, Ideum, and others, we produce webcasts, other multi-media, and print resources for use by school and informal educators nation-wide. We provide training and professional development to K-12 educators, museum personnel, amateur astronomers, Girl Scout leaders, etc., so they can implement their own outreach programs taking advantage of our resources. A coordinated approach promotes multiple programs occurring each year under a common theme. We will report lessons learned from several years of experience, and strategies for growth and sustainability. We will also share our plans for "Ancient Observatories - Timeless Knowledge" our theme for Sun-Earth Day 2005, which will feature solar alignments at ancient sites that mark the equinoxes and/or solstices. The video and webcast programming will feature several sites including: Chaco Canyon (New Mexico), Hovenweep (Utah), and Chichen Itza (Mexico). Many of these sites present unique opportunities to develop authentic cultural connections to Native Americans, highlighting the importance of the Sun across the ages.

  7. Sun-Earth Day: Reaching the Education Audience by Informal Means

    Thieman, J.; Lewis, E.; Cline, T.

    2010-01-01

    For ten years the Sun-Earth Day program has promoted Heliophysics education to ever larger audiences through events centered on attractive annual themes. What originally started out as a one day event quickly evolved into a series of programs and events that occur throughout the year culminating with a celebration on or near the Spring Equinox. The events are often formal broadcasts or webcasts seeking to convey the science behind the latest solar-terrestrial mission discoveries. This has been quite successful, but it is clear that the younger generation increasingly depends on social networking approaches and informal news transmission for learning what is happening in the world around them. For 2010, the Sun-Earth Day team put emphasis on using informal approaches to bring the theme to the audience. The main event, a webcast from the NASA booth at the National Science Teachers Association (NSTA) annual meeting by the NASA EDGE group, took a lighthearted and offbeat approach to interviewing scientists and educators about Heliophysics news. NASA EDGE programs are unscripted and unpredictable, and that represents a different approach to getting the message across. The webcast was supplemented by a number of social networking avenues. The Sun-Earth Day program explored a wide range of social media applications including Facebook, Twitter, NING, podcasting, iPhone apps, etc. Each of these offers unique and effective methods to promote Heliophysics content and mission related highlights. The facebook site was quite popular and message posting there told the Sun-Earth Day story piece by piece. The same could be said of twittering and the tweetup held at the NSTA site. Has all of this been effective? Results are still being gathered, but anecdotal responses from the world seem very positive. What other methods might be used in the future to bring the science to a personal hands-on, interactive experience? Outcomes: Participants will: (1) Be introduced to the Sun-Earth

    2006-01-01

    This Second Edition of Sun, Earth and Sky updates the popular text by providing comprehensive accounts of the most recent discoveries made by five modern solar spacecraft during the past decade. Their instruments have used sound waves to peer deep into the Sun’s inner regions and measure the temperature of its central nuclear reactor, and extended our gaze far from the visible Sun to record energetic outbursts that threaten Earth. Breakthrough observations with the underground Sudbury Neutrino Observatory are also included, which explain the new physics of ghostly neutrinos and solve the problematic mismatch between the predicted and observed amounts of solar neutrinos. This new edition of Sun, Earth and Sky also describes our recent understanding of how the Sun’s outer atmosphere is heated to a million degrees, and just where the Sun’s continuous winds come from. As humans we are more intimately linked with our life-sustaining Sun than with any other astronomical object, and the new edition therefore p...

    Science.gov (United States)

    Thieman, J. R.

    The NASA Sun-Earth Connection Education Forum (SECEF) has the responsibility of using the latest science results from the study of solar physics, space physics, and aeronomy to inspire students in the classroom and to inform the public in general. SECEF works with NASA's Sun-Earth Connection spaceflight missions to accomplish this goal. Each year the missions and SECEF combine to promote their science through a major event designed to attract the attention of all. In late 2004 and 2005 the event will be the study of solar observatories created by ancient peoples and a comparison of their knowledge and culture to present understanding. Two solar observatory sites will be featured, Chaco Canyon in the U.S. and Chichen Itza in Mexico. There are many other places throughout the world that could also be featured as solar observatories and some of these may be described on the SECEF web site or used in future occurrences. Special emphasis is placed on events associated with the solstice and equinox dates. It is hoped that there will be happenings around the world on these days and SECEF will work with many museums, science centers, and other groups to help make this happen. Plans for the 2005 Ancient Observatories event and possible future events on the same subject will be described.

    In this paper we address the feasibility of capturing small Near-Earth Asteroids (NEAs) into the vicinity of the Sun-Earth L2 libration point using a continuous-thrust propulsion system assumed to be attached to the asteroid. The vicinity of this libration point is a gateway to the Earth-Moon neighborhood and using it for capture, or for transit, small NEAs could be interesting for mining or science purposes.

    The three-year life of an EPO grant can be a journey guided by clear goals and enriched by collaborative and outreach opportunities connecting Space sciences to Earth sciences for both K-12 and public audiences. This point is illustrated by two EPO projects funded by NASA Sun-Earth Connection research grants to the High Altitude Observatory (HAO) at the National Center for Atmospheric Research. They are entering their final year coordinated by the Office of Education and Outreach at University Corporation for Atmospheric Research. The content focus of both projects is well aligned with HAO's research mission and the expertise of our scientists, addressing solar dynamics, space weather, and the impacts of solar events on the magnetosphere, as well as societies inhabiting Earth's surface. The first project (Gang Lu, PI) develops presentation resources, inquiry activities, and tips that will help HAO scientists be better prepared to visit K-12 classrooms. Unexpectedly, the simultaneous development of a Teachers' Guide to NCAR's new Climate Discovery exhibit, which takes an Earth system approach to climate and global change, has created a niche for this EPO resource to be revised and repurposed for a needed unit in the guide about the exhibit's graphic panels on Sun-Earth connections. The second project (Art Richmond, PI) engages two high school "Teachers in Residence" to develop resources they can utilize with their students. Excited by exceptional educational graphics and animations in the new Physics of the Aurora: Earth Systems module co-produced by HAO and the COMET Program for advanced undergraduate courses, they chose to adapt appropriate sections of the module to enrich Earth science and math concepts addressed in their 9th and 10th grade astronomy and general physics classes. Simultaneously, the Windows to the Universe web site, which continuously updates space science content and is now developing a new Space Weather section with support from the Center for

  13. Mission to the Sun-Earth L5 Lagrangian Point: An Optimal Platform for Space Weather Research

    2015-04-01

    The Sun-Earth Lagrangian L5 point is a uniquely advantageous location for space weather research and monitoring. It covers the "birth-to-impact" travel of solar transients; it enables imaging of solar activity at least 3 days prior to a terrestrial viewpoint and measures the solar wind conditions 4-5 days ahead of Earth impact. These observations, especially behind east limb magnetograms, will be a boon for background solar wind models, which are essential for coronal mass ejection (CME) and shock propagation forecasting. From an operational perspective, the L5 orbit is the space weather equivalent to the geosynchronous orbit for weather satellites. Optimal for both research and monitoring, an L5 mission is ideal for developing a Research-to-Operations capability in Heliophysics.

  15. Orbit Determination Error Analysis Results for the Triana Sun-Earth L2 Libration Point Mission

    Science.gov (United States)

    Marr, G.

    2003-01-01

    Using the NASA Goddard Space Flight Center's Orbit Determination Error Analysis System (ODEAS), orbit determination error analysis results are presented for all phases of the Triana Sun-Earth L1 libration point mission and for the science data collection phase of a future Sun-Earth L2 libration point mission. The Triana spacecraft was nominally to be released by the Space Shuttle in a low Earth orbit, and this analysis focuses on that scenario. From the release orbit a transfer trajectory insertion (TTI) maneuver performed using a solid stage would increase the velocity be approximately 3.1 km/sec sending Triana on a direct trajectory to its mission orbit. The Triana mission orbit is a Sun-Earth L1 Lissajous orbit with a Sun-Earth-vehicle (SEV) angle between 4.0 and 15.0 degrees, which would be achieved after a Lissajous orbit insertion (LOI) maneuver at approximately launch plus 6 months. Because Triana was to be launched by the Space Shuttle, TTI could potentially occur over a 16 orbit range from low Earth orbit. This analysis was performed assuming TTI was performed from a low Earth orbit with an inclination of 28.5 degrees and assuming support from a combination of three Deep Space Network (DSN) stations, Goldstone, Canberra, and Madrid and four commercial Universal Space Network (USN) stations, Alaska, Hawaii, Perth, and Santiago. These ground stations would provide coherent two-way range and range rate tracking data usable for orbit determination. Larger range and range rate errors were assumed for the USN stations. Nominally, DSN support would end at TTI+144 hours assuming there were no USN problems. Post-TTI coverage for a range of TTI longitudes for a given nominal trajectory case were analyzed. The orbit determination error analysis after the first correction maneuver would be generally applicable to any libration point mission utilizing a direct trajectory.

    The aim of this paper is to study the capture of small Near Earth Objects (NEOs) into the Sun-Earth L2 using low-thrust propulsion for mining or science purposes. As it is well known, the vicinity of these points is inside a net of dynamical channels suitable for the transport in the Earth-Moon neighborhood, so different final destinations from here could be easily considered. Asteroids with very small mass and not representing a potential hazard are analyzed. An initial pruning o...

  17. Minimum time solar sailing from geosynchronous orbit to the sun-earth L2 point

    Science.gov (United States)

    Hur, Sun H.; Bryson, Arthur E., Jr.

    1992-08-01

    An approximate time-optimal of a solar sail from a geosynchronous orbit to the sun-earth L2 libration point is found using a combined method of local optimization and single shooting. The local optimization strategy is based on maximizing the time rate of change of an energy variable at each time. This strategy overcomes the numerical difficulties associated with solving optimal control problems of long duration like the solar sail transfer problem. The single shooting portion of the method is employed to meet the terminal constraints. The combined method can be applied to other optimal low thrust transfer problems of long duration.

    CAWSES (Climate and Weather of the Sun-Earth System) is the most important scientific program of SCOSTEP (Scientific Committee on Solar-Terrestrial Physics). CAWSES has triggered a scientific priority program within the German Research Foundation for a period of 6 years. Approximately 30 scientific institutes and 120 scientists were involved in Germany with strong links to international partners. The priority program focuses on solar influence on climate, atmospheric coupling processes, and space climatology.

  19. Long Term Missions at the Sun-Earth Libration Point L1: ACE, SOHO, and WIND

    Science.gov (United States)

    Roberts, Craig E.

    2011-01-01

    Three heliophysics missions -- the Advanced Composition Explorer (ACE), Solar Heliospheric Observatory (SOHO), and the Global Geoscience WIND -- have been orbiting the Sun-Earth interior libration point L1 continuously since 1997, 1996, and 2004, respectively. ACE and WIND (both NASA missions) and SOHO (an ESA-NASA joint mission) are all operated from the NASA Goddard Space Flight Center (GSFC). While ACE and SOHO have been dedicated libration point orbiters since their launches, WIND has had also a remarkable 10-year career flying a deep-space, multiple lunar-flyby trajectory prior to 2004. That era featured 36 targeted lunar flybys with excursions to both L1 and L2 before its final insertion in L1 orbit. A figure depicts the orbits of the three spacecraft, showing projections of the orbits onto the orthographic planes of a solar rotating ecliptic frame of reference. The SOHO orbit is a quasi-periodic halo orbit, where the frequencies of the in-plane and out-of-plane motions are practically equal. Such an orbit is seen to repeat itself with a period of approximately 178 days. For ACE and WIND, the frequencies of the in-plane and out-of-plane motions are unequal, giving rise to the characteristic Lissajous motion. ACE's orbit is of moderately small amplitude, whereas WIND's orbit is a large-amplitude Lissajous of dimensions close to those of the SOHO halo orbit. As motion about the collinear points is inherently unstable, stationkeeping maneuvers are necessary to prevent orbital decay and eventual escape from the L1 region. Though the three spacecraft are dissimilar (SOHO is a 3-axis stabilized Sun pointer, WIND is a spin-stabilized ecliptic pole pointer, and ACE is also spin-stabilized with its spin axis maintained between 4 and 20 degrees of the Sun), the stationkeeping technique for the three is fundamentally the same. The technique consists of correcting the energy of the orbit via a delta-V directed parallel or anti-parallel to the Spacecraft-to-Sun line. SOHO

    2003-01-01

    The Triana spacecraft was designed to be launched by the Space Shuttle. The nominal Triana mission orbit will be a Sun-Earth L1 libration point orbit. Using the NASA Goddard Space Flight Center's Orbit Determination Error Analysis System (ODEAS), orbit determination (OD) error analysis results are presented for all phases of the Triana mission from the first correction maneuver through approximately launch plus 6 months. Results are also presented for the science data collection phase of the Fourier Kelvin Stellar Interferometer Sun-Earth L2 libration point mission concept with momentum unloading thrust perturbations during the tracking arc. The Triana analysis includes extensive analysis of an initial short arc orbit determination solution and results using both Deep Space Network (DSN) and commercial Universal Space Network (USN) statistics. These results could be utilized in support of future Sun-Earth libration point missions.

    1997-01-01

    The objective of this project has been to complete the archiving of energetic (10 eV/epsilon - 18 keV/epsilon) ion composition data from the Lockheed Plasma Composition Experiment on the International Sun-Earth Explorer One (ISEE 1) satellite, using a particular data format that had previously been approved by NASA and the NSSDC. That same format, a combination of ion velocity moments and differential flux spectra, had been used in 1991 to archive, at the NSSDC, the first 28 months (the "Prime" period of ISEE investigations) of data from the Lockheed instrument under NASA Contract NAS5-33047. With the completion of this project, the almost 4 1/2-year time span of these unique data is now covered by a very compact set, approximately 1 gigabyte in total, of electronic files with physical quantities, all in ASCII. The files are organized by data type and time of data acquisition, in Universal Time, and named according to year and day of year. Each calendar day has five separate files (five types of data), the lengths of which vary from day to day, depending on the instrument mode of operation. The data format and file structure are described in detail in appendices 1 and 2. The physical medium consists of high-density (6250 cpi) 9-track magnetic tapes, complemented by a set of hardcopy line plots of certain plasma parameters. In this case there are five tapes, to be added to the six previous ones from 1991, and 25 booklets of plots, one per month, to be added to the previous 28. The tapes, including an extra standard-density (1600 cpi) tape with electronic versions of the Data User's Guide and self-guiding VAX/VMS command files, and the hardcopy plots are being boxed for shipment to the NSSDC.

  3. Understanding the Sun-Earth Libration Point Orbit Formation Flying Challenges For WFIRST and Starshade

    Science.gov (United States)

    Webster, Cassandra M.; Folta, David C.

    2017-01-01

    In order to fly an occulter in formation with a telescope at the Sun-Earth L2 (SEL2) Libration Point, one must have a detailed understanding of the dy-namics that govern the restricted three body system. For initial purposes, a linear approximation is satisfactory, but operations will require a high-fidelity modeling tool along with strategic targeting methods in order to be successful. This paper focuses on the challenging dynamics of the transfer trajectories to achieve the relative positioning of two spacecraft to fly in formation at SEL2, in our case, the Wide-Field Infrared Survey Telescope (WFIRST) and a proposed Starshade. By modeling the formation transfers using a high fidelity tool, an accurate V approximation can be made to as-sist with the development of the subsystem design required for a WFIRST and Starshade formation flight mission.

  4. Solar radiation pressure used for formation flying control around the Sun-Earth libration point

    Solar radiation pressure is used to control the formation flying around the L2 libration point in the Sun-Earth system. Formation flying control around a halo orbit requires a very small thrust that cannot be satisfied by the latest thrusters. The key contribution of this paper is that the continuous low thrust is produced by solar radiation pressure to achieve the tight formation flying around the libration point. However, only certain families of formation types can be controlled by solar radiation pressure since the direction of solar radiation pressure is restricted to a certain range. Two types of feasible formations using solar radiation pressure control are designed. The conditions of feasible formations are given analytically. Simulations are presented for each case, and the results show that the formations are well controlled by solar radiation pressure.

  5. Phasing Delta-V for transfers from Sun-Earth halo orbits to the Moon

    Chen, Hongru; Kawakatsu, Yasuhiro; Hanada, Toshiya

    2016-10-01

    Inspired by successful extended missions such as the ISEE-3, an investigation for the extended mission that involves a lunar encounter following a Sun-Earth halo orbit mission is considered valuable. Most previous studies present the orbit-to-orbit transfers where the lunar phase is not considered. Intended for extended missions, the present work aims to solve for the minimum phasing ∆V for various initial lunar phases. Due to the solution multiplicity of the two-point boundary value problem, the general constrained optimization algorithm that does not identify multiple feasible solutions is shown to miss minima. A two-step differential corrector with a two-body Lambert solver is developed for identifying multiple solutions. The minimum ∆V associated with the short-way and long-way approaches can be recovered. It is acquired that the required ∆V to cover all initial lunar phases is around 45 m/s for the halo orbit with out-of-plane amplitude Az greater than 3.5×105 km, and 14 m/s for a small halo orbit with Az=1×105 km. In addition, the paper discusses the phasing planning based on the ∆V result and the shift of lunar phase with halo orbit revolution.

    A growing interest in formation flying satellites demands development and analysis of control and estimation algorithms for station-keeping and formation maneuvering. This thesis discusses the development of a discrete linear-quadratic- regulator control algorithm for formations in the vicinity of the L2 sun-earth libration point. The development of an appropriate Kalman filter is included as well. Simulations are created for the analysis of the station-keeping and various formation maneuvers of the Stellar Imager mission. The simulations provide tracking error, estimation error, and control effort results. From the control effort, useful design parameters such as AV and propellant mass are determined. For formation maneuvering, the drone spacecraft track to within 4 meters of their desired position and within 1.3 millimeters per second of their desired zero velocity. The filter, with few exceptions, keeps the estimation errors within their three-sigma values. Without noise, the controller performs extremely well, with the drones tracking to within several micrometers. Bach drone uses around 1 to 2 grams of propellant per maneuver, depending on the circumstances.

    "Tell me and I forget, teach me and I may remember, involve me and I learn." -Benjamin Franklin Understanding the spatial relationships between the sun, Earth and Moon is fundamental to any basic earth science education. Since both of the following concepts involve shadows on three-dimensional spheres, seeing them on paper is not often conducive to understanding. In the first activity, students use five Styrofoam balls painted to look like the sun and the four positions of the earth in each season. Students position the Earth-balls in their correct order around the sun and translate what they are seeing onto paper. In the second activity, students hold up a Styrofoam ball painted half white, half black. A picture of the sun is projected at the front of the classroom. They move the ball around their heads as if they were the Earth, keeping the lit side of the moon always facing the sun. They then draw the phases of the moon as they see them.

  8. Optimal Sunshade Configurations for Space-Based Geoengineering near the Sun-Earth L1 Point.

    Full Text Available Within the context of anthropogenic climate change, but also considering the Earth's natural climate variability, this paper explores the speculative possibility of large-scale active control of the Earth's radiative forcing. In particular, the paper revisits the concept of deploying a large sunshade or occulting disk at a static position near the Sun-Earth L1 Lagrange equilibrium point. Among the solar radiation management methods that have been proposed thus far, space-based concepts are generally seen as the least timely, albeit also as one of the most efficient. Large occulting structures could potentially offset all of the global mean temperature increase due to greenhouse gas emissions. This paper investigates optimal configurations of orbiting occulting disks that not only offset a global temperature increase, but also mitigate regional differences such as latitudinal and seasonal difference of monthly mean temperature. A globally resolved energy balance model is used to provide insights into the coupling between the motion of the occulting disks and the Earth's climate. This allows us to revise previous studies, but also, for the first time, to search for families of orbits that improve the efficiency of occulting disks at offsetting climate change on both global and regional scales. Although natural orbits exist near the L1 equilibrium point, their period does not match that required for geoengineering purposes, thus forced orbits were designed that require small changes to the disk attitude in order to control its motion. Finally, configurations of two occulting disks are presented which provide the same shading area as previously published studies, but achieve reductions of residual latitudinal and seasonal temperature changes.

    NASA's Sun Earth Connection Active Archive (SECAA) provides access to a large volume of data and models that are of relevance to Ionospheric, Thermospheric and Mesospheric (ITM) physics. SECAA has developed a number of web systems to facilitate user access to this important data source and is making these services available through Web Services (or Application Programming Interfaces, API) directly to applications such as VxOs. The Coordinated Data Analysis web (CDAWeb) lets user plot data using a wide range of parameter display options including mapped images and movies. Capabilities also include parameter listings and data downloads in CDF and ASCII format. CDAWeb provides access to data from most of NASA's currently operating space science satellites and many of the earlier missions; of special ITM interest are DE-2, ISIS, FAST, Equator-S, and TIMED. SECAA maintains and supports the Common Data Format (CDF) including software to read and write CDF files. Most recently translator services have been added for CDF translations to/from netCDF, FITS, CDFXML, and ASCII. The SSCWeb interface enables users to plot orbits for the majority of space physics satellites (including TIMED, UARS, DMSP, NOAA, LANL etc.) and to query for magnetic field line conjunctions between multiple spacecraft and ground stations and for magnetic region occupancy. Recently an Interactive 3-D orbit viewer was added to SSCWeb. Access to legacy data from older ITM satellite missions is provided through the ATMOWeb system with the ability to generate plots and download data subsets in ASCII format. Recently added capabilities include the option to filter the data using an upper and lower boundary for any one of the data set parameters. We will also present the newest version of the web portal to SECAA's models catalog, ftp archive, and web interfaces. The web interfaces (Fortran, C, Java) let users compute, list, plot, and download model parameters for selected models (IRI, IGRF, MSIS/CIRA, AE

    2011-01-01

    The data analysis tool of choice for many Sun-Earth Connection missions is the Interactive Data Language (IDL) by ITT VIS. The increasing amount of data produced by these missions and the increasing complexity of image processing algorithms requires access to higher computing power. Parallel computing is a cost-effective way to increase the speed of computation, but algorithms oftentimes have to be modified to take advantage of parallel systems. Enhancing IDL to work on clusters gives scientists access to increased performance in a familiar programming environment. The goal of this project was to enable IDL applications to benefit from both computing clusters as well as graphics processing units (GPUs) for accelerating data analysis tasks. The tool suite developed in this project enables scientists now to solve demanding data analysis problems in IDL that previously required specialized software, and it allows them to be solved orders of magnitude faster than on conventional PCs. The tool suite consists of three components: (1) TaskDL, a software tool that simplifies the creation and management of task farms, collections of tasks that can be processed independently and require only small amounts of data communication; (2) mpiDL, a tool that allows IDL developers to use the Message Passing Interface (MPI) inside IDL for problems that require large amounts of data to be exchanged among multiple processors; and (3) GPULib, a tool that simplifies the use of GPUs as mathematical coprocessors from within IDL. mpiDL is unique in its support for the full MPI standard and its support of a broad range of MPI implementations. GPULib is unique in enabling users to take advantage of an inexpensive piece of hardware, possibly already installed in their computer, and achieve orders of magnitude faster execution time for numerically complex algorithms. TaskDL enables the simple setup and management of task farms on compute clusters. The products developed in this project have the

    Full Text Available Tungiasis is a neglected parasitic skin disease caused by the permanent penetration of the female sand flea (also called jigger flea Tunga penetrans into the skin of its host. After penetration, most commonly on the feet, the flea undergoes an impressing hypertrophy, and some days later the abdominal segments of the flea have enlarged up to the size of about 1 cm. The flea infestation is associated with poverty and occurs in many resource-poor communities in the Caribbean, South America and Africa. In this review, a historical overview on tungiasis is given. The natural history, pathology, epidemiology, diagnosis, therapy and control of the parasitic skin disease are discussed. It is concluded that tungiasis is an important parasitosis causing considerable morbidity in affected populations. Future studies are needed to increase the knowledge on the biology, pathophysiology, epidemiology, therapy and control of the ectoparasite.A tungíase é uma ectoparasitose negligenciada causada pela penetração permanente da pulga Tunga penetrans (também chamada de bicho de pé na pele de seu hospedeiro.

  18. Research on Control Method of Keeping Flight Formation by Using SDRE on the Sun-Earth Libration Points

    Directory of Open Access Journals (Sweden)

    2017-01-01

    Full Text Available Keeping the flying formation of spacecraft is a key problem which needs to be solved in deep space exploration missions. In this paper, the nonlinear dynamic model of formation flying is established and a series of transformations are carried out on this model equation. By using SDRE (State-Dependent Riccati Equation algorithm, the optimal control of flying formation is realized. Compared with the traditional control method based on the average orbit elements and LQR (Linear Quadratic Regulator control method, the SDRE control method has higher control precision and is more suitable for the advantages of continuous control in practical engineering. Finally, the parameter values of the sun-earth libration point L2 are substituted in the equation and simulation is performed. The simulation curves of SDRE controller are compared with LQR controller. The results show that the SDRE controllers time cost is less than the LQR controllers and the former’s fuel consumption is less than the latter’s in the system transition process.

    This paper addresses lunar escape maneuvers of the first Chinese Sun-Earth L2 libration point mission by the CHANG'E-2 satellite, which is also the world's first satellite to reach the L2 point from a lunar orbit. The lunar escape maneuvers are heavily constrained by the remaining propellant and the condition of telemetry, track and command, among others. First, these constraints are analyzed and summarized to design a target L2 Lissajous orbit and an initial transfer trajectory. Second, the maneuver mathematical models are studied. The multilevel maneuver schemes which consist of phasing maneuvers and a final lunar escape maneuver are designed for actual operations. Based on the scheme analysis and comparison, the 2-maneuver scheme with a 5.3-h-period phasing orbit is ultimately selected. Finally, the mission status based on the scheme is presented and the control operation results are discussed in detail. The methodology in this paper is especially beneficial and applicable to a future multi-mission instance in the deep space exploration.

    Leiva, A. M.; Briozzo, C. B.

    In a previous work we successfully implemented a control algorithm to stabilize unstable periodic orbits in the Sun-Earth-Moon Quasi-Bicircular Problem (QBCP). Applying the same techniques, in this work we stabilize an unstable trajectory performing fast transfers between the Earth and the Moon in a dynamical system similar to the QBCP but incorporating the gravitational perturbation of the planets Mercury, Venus, Mars, Jupiter, Saturn, Uranus, and Neptune, assumed to move on circular coplanar heliocentric orbits. In the control stage we used as a reference trajectory an unstable periodic orbit from the unperturbed QBCP. We performed 400 numerical experiments integrating the trajectories over time spans of ~40 years, taking for each one random values for the initial positions of the planets. In all cases the control impulses applied were larger than 20 cm/s, consistently with realistic implementations. The minimal and maximal yearly mean consumptions were ~10 m/s and ~71 m/s, respectively. FULL TEXT IN SPANISH

    In the 6th edition of the Chinese Space Trajectory Design Competition held in 2014, a near-Earth asteroid sample-return trajectory design problem was released, in which the motion of the spacecraft is modeled in multi-body dynamics, considering the gravitational forces of the Sun, Earth, and Moon. It is proposed that an electric-propulsion spacecraft initially parking in a circular 200-km-altitude low Earth orbit is expected to rendezvous with an asteroid and carry as much sample as possible back to the Earth in a 10-year time frame. The team from the Technology and Engineering Center for Space Utilization, Chinese Academy of Sciences has reported a solution with an asteroid sample mass of 328 tons, which is ranked first in the competition. In this article, we will present our design and optimization methods, primarily including overall analysis, target selection, escape from and capture by the Earth-Moon system, and optimization of impulsive and low-thrust trajectories that are modeled in multi-body dynamics. The orbital resonance concept and lunar gravity assists are considered key techniques employed for trajectory design. The reported solution, preliminarily revealing the feasibility of returning a hundreds-of-tons asteroid or asteroid sample, envisions future space missions relating to near-Earth asteroid exploration.

    2004-01-01

    In this paper, we present a method for trajectory generation and adaptive full-state feedback control to facilitate spacecraft formation flying near the Sun-Earth L2 Lagrange point. Specifically, the dynamics of a spacecraft in the neighborhood of a Halo orbit reveals that there exist quasi-periodic orbits surrounding the Halo orbit. Thus, a spacecraft formation is created by placing a leader spacecraft on a desired Halo orbit and placing follower spacecraft on desired quasi-periodic orbits. To produce a formation maintenance controller, we first develop the nonlinear dynamics of a follower spacecraft relative to the leader spacecraft. We assume that the leader spacecraft is on a desired Halo orbit trajectory and the follower spacecraft is to track a desired quasi-periodic orbit surrounding the Halo orbit. Then, we design an adaptive, full-state feedback position tracking controller for the follower spacecraft providing an adaptive compensation for the unknown mass of the follower spacecraft. The proposed control law is simulated for the case of the leader and follower spacecraft pair and is shown to yield global, asymptotic convergence of the relative position tracking errors.

    The Spanish Space Weather Service SeNMEs, www.senmes.es, is a portal created by the SRG-SW of the Universidad de Alcalá, Spain, to meet societal needs of near real-time space weather services. This webpage-portal is divided in different sections to fulfill users needs about space weather effects: radio blackouts, solar energetic particle events, geomagnetic storms and presence of geomagnetically induced currents. In less than one year of activity, this service has released a daily report concerning the solar current status and interplanetary medium, informing about the chances of a solar perturbation to hit the Earth's environment. There are also two different forecasting tools for geomagnetic storms, and a daily ionospheric map. These tools allow us to nowcast a variety of solar eruptive events and forecast geomagnetic storms and their recovery, including a new local geomagnetic index, LDiñ, along with some specific new scaling. In this paper we also include a case study analysed by SeNMEs. Using different high resolution and cadence data from space-borne solar telescopes SDO, SOHO and GOES, along with ionospheric and geomagnetic data, we describe the Sun-Earth feature chain for the event.

The proposed INvestigation of Solar-Terrestrial Activity aNd Transients (INSTANT) mission is designed to identify how solar coronal magnetic fields drive eruptions, mass transport and particle acceleration that impact the Earth and the heliosphere. INSTANT is the first mission designed to (1) obtain measurements of coronal magnetic fields from space and (2) determine coronal mass ejection (CME) kinematics with unparalleled accuracy. Thanks to innovative instrumentation at a vantage point that provides the most suitable perspective view of the Sun-Earth system, INSTANT would uniquely track the whole chain of fundamental processes driving space weather at Earth. We present the science requirements, payload and mission profile that fulfill ambitious science objectives within small mission programmatic boundary conditions.

  6. Student Mastery of the Sun-Earth-Moon System in a Flipped Classroom of Pre-service Elementary Education Students

    2014-01-01

    One of the current trends in pedagogy at all levels(K-college) is the so-called ‘flipped classroom’, in which students prepare for a class meeting through self-study of the material. It is based on a rejection of the classic model of the faculty member as the ‘sage on the stage’ instead, responsibility for learning shifts to the individual student. The faculty member takes on the role of learning facilitator or mentor, and focuses the students’ learning by crafting and administering timely formative assessments (in multiple formats and applied multiple times) that aid both students and the faculty member in tracking the students’ mastery of the learning outcomes. In a flipped, freshman-only, section of SCI 111 Elementary Earth-Physical Sciences (a required introductory science course for pre-service elementary school teachers) the students learned through a combination of individual and group hands-on in-class activities, technology (including PowerPoint presentations and short videos viewed prior to attending class), in-class worksheets, and in-class discussions. Students self-differentiated in how they interacted with the available teaching materials, deciding which activities to spend the most time on based on their individual needs (based on an online quiz taken the night before the class period, and their personal self-confidence with the material). Available in-class activities and worksheets were developed by the faculty member based on student scores on the online quiz as well as personal messages submitted through the course management system the night before the class meeting. While this placed a significant burden on the faculty member in terms of course preparation, it allowed for just-in-time teaching to take place. This poster describes the results of student mastery of content centered on the sun-earth-moon system (specifically seasons, moon phases, and eclipses) as compared to traditional classroom sections.

    The Sun is enveloped by a hot, tenuous million-degree corona that expands to create a continuous solar wind that sweeps past all the planets and fills the heliosphere. The solar wind is modulated by strong gusts that are initiated by powerful explosions on the Sun, including solar flares and coronal mass ejections. This dynamic, invisible outer atmosphere of the Sun is currently under observation with the soft X-ray telescope aboard the Yohkoh spacecraft, whose results are presented. We also show observations from the Ulysses spacecraft that is now passing over the solar pole, sampling the solar wind in this region for the first time. Two other spacecraft, Voyager 1 and 2, have recently detected the outer edge of the invisible heliosphere, roughly halfway to the nearest star. Magnetic solar activity, the total radiative output from the Sun, and the Earth's mean global surface temperature all vary with the 11-year sunspot cycle in which the total number of sunspots varies from a maximum to a minimum and back to a maximum again in about 11 years. The terrestrial magnetic field hollows out a protective magnetic cavity, called the magnetosphere, within the solar wind. This protection is incomplete, however, so the Sun feeds an unseen world of high-speed particles and magnetic fields that encircle the Earth in space. These particles endanger spacecraft and astronauts, and also produce terrestrial aurorae. An international flotilla of spacecraft is now sampling the weak points in this magnetic defense. Similar spacecraft have also discovered a new radiation belt, in addition to the familiar Van Allen belts, except fed by interstellar ions instead of electrons and protons from the Sun.

    Full Text Available Infection of humans with embryonated eggs of Toxocara canis (larva migrans remains asymptomatic, or results in covert or common toxocarosis, visceral larva migrans syndrome, or ophthalmologic and neurologic impairment. Though neurological manifestations of Toxocara canis larvae are rare, toxocarosis remains an important differential diagnosis of various neurological disorders. Manifestations of the central nervous system are dementia, meningo-encephalitis, myelitis, cerebral vasculitis, epilepsy, or optic neuritis. Manifestations of the peripheral nervous system comprise radiculitis, affection of cranial nerves, or musculo-skeletal involvement. If toxocarosis is neglected, ignored, or refused as a differential of these abnormalities, it may be easily overlooked for years. Early recognition and treatment of the infection is, however, of paramount importance since it reduces morbidity and mortality and the risk of secondary superinfection. Like the visceral manifestations, neurological manifestations of toxocarosis are treated by benzimidazole components, most frequently albendazole, corticosteroids, or diethylcarbamazine. If detected and treated early, the prognosis of neurological manifestations of toxocarosis is favourable.Infecção humana com ovos embrionados de Toxocara canis (larva migrans pode permanecer assintomática ou resultar em toxocaríase acentuada ou comum, síndrome da larva migrans visceral ou manifestações neurológicas ou oftalmológicas.

    Full Text Available Pinworm infection was prospectively studied during one year in 469 children attending three day care centers. Each child was examined at six months intervals using up to three perianal swabs with adhesive tape. Those found infected were treated with mebendazole. At the beginning of the study we found a prevalence of 28% that dropped to 13% and 12% in the following study periods. The reinfection rate was twice the incidence rate in both study periods. We also found a small percentage (10% of the children reinfected in most or all study periods. There was a high correlation between reinfection and perianal itching. Our results add further knowledge to the epidemiology of intestinal parasites in day care centers.Infecção por oxiuros foi estudada prospectivamente durante um ano em 469 crianças de três creches. Cada criança foi examinada com intervalos de 6 meses usando até 3 esfregaços perianais com fita adesiva. As que estavam infectadas foram tratadas com mebendazole. No início do estudo foi encontrada prevalência de 28% que caiu para 13% e 12% nos períodos de estudo posteriores. A freqüência de reinfecção foi 2 vezes a incidência em ambos os períodos de estudo. Foi encontrada, também, pequena porcentagem (10% de crianças reinfectadas na maioria ou em todos os períodos de estudo. Existiu elevada correlação entre reinfecção e coceira perianal.

  12. Near-Earth asteroid flyby trajectories from the Sun-Earth L2 for Chang'e-2's extended flight

    2013-02-01

    Driven by curiosity about possible flight options for the Chang'e-2 spacecraft after it remains at the Sun-Earth L2 point, effective approaches were developed for designing preliminary fuel-optimal near-Earth asteroid flyby trajectories. The approaches include the use of modified unstable manifolds, grid search of the manifolds' parameters, and a two-impulse maneuver for orbital phase matching and z-axis bias change, and are demonstrated to be effective in asteroid target screening and trajectory optimization. Asteroid flybys are expected to be within a distance of 2 × 107 km from the Earth owing to the constrained Earth-spacecraft communication range. In this case, the spacecraft's orbital motion is significantly affected by the gravities of both the Sun and the Earth, and therefore, the concept of the "heliocentric oscillating-Kepler orbit" is proposed, because the classical orbital elements of the flyby trajectories referenced in the heliocentric inertial frame oscillate significantly with respect to time. The analysis and results presented in this study show that, among the asteroids whose orbits are the most accurately predicted, "Toutatis", "2005 NZ6", or "2010 CL19" might be encountered by Chang'e-2 in late 2012 or 2013 with total impulses less than 100m/s.

    This paper describes the scientific rationale for an L5 mission and a partial list of key scientific instruments the mission should carry. The L5 vantage point provides an unprecedented view of the solar disturbances and their solar sources that can greatly advance the science behind space weather. A coronagraph and a heliospheric imager at L5 will be able to view CMEs broadsided, so space speed of the Earth-directed CMEs can be measured accurately and their radial structure discerned. In addition, an inner coronal imager and a magnetograph from L5 can give advance information on active regions and coronal holes that will soon rotate on to the solar disk. Radio remote sensing at low frequencies can provide information on shock-driving CMEs, the most dangerous of all CMEs. Coordinated helioseismic measurements from the Sun Earth line and L5 provide information on the physical conditions at the base of the convection zone, where solar magnetism originates. Finally, in situ measurements at L5 can provide information on the large-scale solar wind structures (corotating interaction regions (CIRs)) heading towards Earth that potentially result in adverse space weather.

    The Lockheed plasma composition experiment on the ISEE 1 spacecraft has provided one of the largest and most varied sets of data on earth's energetic plasma environment, covering both the solar wind, well beyond the bow shock, and the near equatorial magnetosphere to a distance of almost 23 earth radii. This report is an overview of the last four years of data analysis and archiving. The archiving for NSSDC includes most data obtained during the initial 28-months of instrument operation, from early November 1977 through the end of February 1980. The data products are a combination of spectra (mass and energy angle) and velocity moments. A copy of the data user's guide and examples of the data products are attached as appendix A. The data analysis covers three major areas: solar wind ions upstream and downstream of the day side bowshock, especially He(++) ions; terrestrial ions flowing upward from the auroral regions, especially H(+), O(+), and He(+) ions; and ions of both solar and terrestrial origins in the tail plasma sheet and lobe regions.

  17. A Full Study on the Sun-Earth Connection of an Earth-Directed CME Magnetic Flux Rope

    CERN Document Server

    Vemareddy, P

    2015-01-01

    We present an investigation of an eruption event of coronal mass ejection (CME) magnetic flux rope (MFR) from source active region (AR) NOAA 11719 on 11 April 2013 utilizing observations from SDO, STEREO, SOHO, and WIND spacecraft. The source AR consists of pre-existing sigmoidal structure stacked over a filament channel which is regarded as MFR system. EUV observations of low corona suggest a further development of this MFR system by added axial flux through tether-cutting reconnection of loops at the middle of sigmoid under the influence of continuous slow flux motions during past two days. Our study implies that the MFR system in the AR is initiated to upward motion by kink-instability and further driven by torus-instability. The CME morphology, captured in simultaneous three-point coronagraph observations, is fitted with Graduated Cylindrical Shell (GCS) model and discerns an MFR topology with orientation aligning with magnetic neutral line in the source AR. This MFR expands self-similarly and is found to...

  18. Improving solar wind persistence forecasts: Removing transient space weather events, and using observations away from the Sun-Earth line

    This study demonstrates two significant ways of improving persistence forecasts of the solar wind, which exploit the relatively unchanging nature of the ambient solar wind to provide 27 day forecasts, when using data from the Lagrangian L1 point. Such forecasts are useful as a prediction tool for the ambient wind, and for benchmarking of solar wind models. We show that solar wind persistence forecasts can be improved by removing transient solar wind features such as coronal mass ejections (CMEs). Using CME indicators to automatically identify CME-contaminated periods in ACE data from 1998 to 2011, and replacing these with solar wind from a previous synodic rotation, persistence forecasts improve (relative to a baseline): skill scores for Bz, a crucial parameter for determining solar wind geoeffectiveness, improve by 7.7 percentage points when using a proton temperature-based indicator with good operational potential. We also show that persistence forecasts can be improved by using measurements away from L1, to reduce the requirement on coronal stability for an entire synodic period, at the cost of reduced lead time. Using STEREO-B data from 2007 to 2013 to create such a reduced lead time persistence forecast, we show that Bz skill scores improve by 17.1 percentage points relative to ACE. Finally, we report on implications for persistence forecasts from any future missions to the L5 Lagrangian point and on the successful operational implementation (in spring 2015) of the normal (ACE-based) and reduced lead time (STEREO-based) persistence forecasts in the Met Office's Space Weather Operations Centre, as well as plans for future improvements.

    The possible reasons why an oil or gas company would seek public equity and financing and a listing on a stock exchange were discussed. This crucial decision for junior companies is often prompted by the need for expansion capital. In the last three years, 456 companies decided to list on the Alberta Stock Exchange (ASE) using the two most commonly used methods of going public: the Exchange Offering Prospectus (EOP) program, and the Junior Capital Pool (JCP) program. The EOP program is a simplified form of prospectus in which the distribution of securities is made through the facilities of the ASE. Companies that do not have significant operating assets, other than cash, nor agreements in place to acquire operating assets, are eligible under the JCP program which involves a two-stage process. Stage one requires the filing and clearing of a prospectus through the Alberta Securities Commission and the listing of the company`s shares on the Exchange. Stage two requires completing a major transaction within 18 months of being listed on the Exchange. Details of the minimum listing requirements for either the EOP or the JCP programs were described.

    The maximum rate (Vmax) of some enzymatic activities related to energy consumption was evaluated in synaptic plasma membranes from rat brain striatum, the synaptic energy state being a crucial factor in neurodegenerative diseases etiopathogenesis. Two types of synaptic plasma membranes were isolated from rats subjected to in vivo treatment with L-acetylcarnitine at two different doses (30 and 60 mg × kg(-1) i.p., 28 days, 5 days/week). The following enzyme activities were evaluated: acetylcholinesterase (AChE); Na(+), K(+), Mg(2+)-ATP-ase; ouabain insensitive Mg(2+)-ATP-ase; Na(+), K(+)-ATP-ase; direct Mg(2+)-ATP-ase; Ca(2+), Mg(2+)-ATP-ase; and low- and high-affinity Ca(2+)-ATP-ase. In control (vehicle-treated) animals, enzymatic activities are differently expressed in synaptic plasma membranes type I (SPM1) with respect to synaptic plasma membranes type II (SPM2), the evaluated enzymatic activities being higher in SPM2. Subchronic treatment with L-acetylcarnitine decreased AChE on SPM1 and SPM2 at the dose of 30 mg × kg(-1). Pharmacological treatment decreased ouabain insensitive Mg(2+)-ATP-ase activity and high affinity Ca(2+)-ATP-ase activity at the doses of 30 and 60 mg × kg(-1) respectively on SPM1, while it decreased Na(+), K(+)-ATP-ase, direct Mg(2+)-ATP-ase and Ca(2+), Mg(2+)-ATP-ase activities at the dose of 30 mg × kg(-1) on SPM2. These results suggest that the sensitivity to drug treatment is different between these two populations of synaptic plasma membranes from the striatum, confirming the micro-heterogeneity of these subfractions, possessing different metabolic machinery with respect to energy consumption and utilization and the regional selective effect of L-acetylcarnitine on cerebral tissue, depending on the considered area. The drug potential effect at the synaptic level in Parkinson's Disease neuroprotection is also discussed with respect to acetylcholine and energy metabolism.

    There are several flight options for the Chang’E-2 spacecraft after its remaining at the Sun-Earth L2 point, for example, impacting the Moon or recapture into lunar orbit, returning to Earth orbit or atmospheric reentry, heading for halo orbits of the Earth-Moon L1 or L2 or the Sun-Earth L1 point, as well as flying by near-Earth asteroids in interplanetary space (Finally, Chang’E-2 successfully implemented a close flyby of Toutatis, a potentially hazardous near-Earth asteroid, on Dec.13, 2012). The analyses of these flight options require designing preliminary transfer trajectories with total velocity impulses no more than 100 m/s in four-body dynamics, in which the motion of the spacecraft is influenced by the gravities of the Sun, Earth, and Moon. In this study, we shall present low-energy Toutatis flyby trajectories from a Sun-Earth L2 quasi-periodic orbit, specifically, via a single lunar gravity assist that is intentionally utilized for exploring potential benefits, compared with the direct transfer manner that is adopted in the practical mission. Compared with the direct transfer trajectories to the asteroid, lunar gravity assist is demonstrated to be capable of saving propellant for the Toutatis flyby mission, and the equivalent velocity impulses are 58.46 m/s.%对于停留在日地系统L2的“嫦娥2号”探测器,其后续飞行方案有多个选项,例如主动撞月或重返月球轨道、返回地球轨道或再入大气、飞往地月系统L1/L2或日地系统L1、进入深空飞越近地小行星(最终,“嫦娥2号”于2012年12月13日成功地实现了对Toutatis小行星的近距离飞越)。探讨上述的飞行方案需要对飞行轨道进行初步设计,总的速度脉冲限制在100 m/s以内并且需要考虑探测器同时受到太阳、地球、月球的引力作用。本研究设计了探测器从日地系统L2出发借力月球实现Toutatis小行星飞越的飞行方案,与直接飞越方案相比

    Full Text Available A expressão pitiríase versicolor define uma infecção fúngica superficial caracterizada por alterações na pigmentação cutânea. O distúrbio de pigmentação é devido à colonização do estrato córneo por um fungo dimórfico, lipofílico, encontrado na flora normal da pele, conhecido como Malassezia furfur. Trata-se de doença prevalente nos trópicos, mas também comum em climas temperados. Há vários tratamentos disponíveis com taxas elevadas de cura, porém as recorrências são freqüentes.Pityriasis versicolor is a superficial fungal infection characterized by changes in skin pigment due to colonization of the stratum corneum by a dimorphic lipophilic fungus of the normal flora of the skin, known as Malassezia furfur.

    1994-05-01

    The Lockheed plasma composition experiment on the ISEE 1 spacecraft has provided one of the largest and most varied sets of data on earth's energetic plasma environment, covering both the solar wind, well beyond the bow shock, and the near equatorial magnetosphere to a distance of almost 23 earth radii. This report is an overview of the last four years of data analysis and archiving. The archiving for NSSDC includes most data obtained during the initial 28-months of instrument operation, from early November 1977 through the end of February 1980. The data products are a combination of spectra (mass and energy angle) and velocity moments. A copy of the data user's guide and examples of the data products are attached as appendix A. The data analysis covers three major areas: solar wind ions upstream and downstream of the day side bowshock, especially He(++) ions; terrestrial ions flowing upward from the auroral regions, especially H(+), O(+), and He(+) ions; and ions of both solar and terrestrial origins in the tail plasma sheet and lobe regions. Copies of publications are attached.

    This work presents the development and construction of the Heliometer of the Observat\\'orio Nacional/MCTI. This instrument is designed to monitor changes on the solar diameter with the accuracy of the next-generation solar satellites. A review of the heliometric method is made and the building and testing of 4 prototypes is described. The instrument has a mirror objective split in dihedral, formed by the hemi-sections of a parabolic mirror. The materials that form the instrument have thermal and mechanical stability to 10^(-7). The number of optical parts is minimized and their quality is greater than {\\lambda}/12. An original software for the automated collection and analysis of the images was developed. With its latest version fully developed, we conducted an observational campaign of 9 days, deriving more than 70000 heliometric images of the Sun. The measured solar diameter has a standard deviation of 0.5 arcseconds, with no instrumental bias, and limited only by the provisional atmospheric modeling. There...

  4. A Closer Earth and the Faint Young Sun Paradox: Modification of the Laws of Gravitation, or Sun/Earth Mass Losses?

    Given a solar luminosity L_Ar = 0.75 L_0 at the beginning of the Archean 3.8 Gyr ago, where L_0 is the present-day one, if the heliocentric distance r of the Earth was r_Ar = 0.956 r_0, the solar irradiance would have been as large as I_Ar = 0.82 I_0. It would allowed for a liquid ocean on the terrestrial surface which, otherwise, would have been frozen, contrary to the empirical evidence. By further assuming that some physical mechanism subsequently displaced the Earth towards its current distance in such a way that the irradiance stayed substantially constant over the entire Archean from 3.8 Gyr to 2.5 Gyr ago, a relative recession rate as large as \\dot r/r \\simeq 3.4 x 10^-11 yr^-1 would have been required. Although such a figure is roughly of the same order of magnitude of the value of the Hubble parameter 3.8 Gyr ago H_Ar = 1.192 H_0 = 8.2 x 10^-11 yr^-1, standard general relativity rules out cosmological explanations for the hypothesized Earth' s recession rate.

    Full Text Available Given a solar luminosity LAr = 0.75L0 at the beginning of the Archean 3.8 Ga ago, where L0 is the present-day one, if the heliocentric distance, r, of the Earth was rAr = 0.956r0, the solar irradiance would have been as large as IAr = 0.82I0. It would have allowed for a liquid ocean on the terrestrial surface, which, otherwise, would have been frozen, contrary to the empirical evidence. By further assuming that some physical mechanism subsequently displaced the Earth towards its current distance in such a way that the irradiance stayed substantially constant over the entire Archean from 3.8 to 2.5 Ga ago, a relative recession per year as large as r˙/r ≈3.4 × 10−11 a−1 would have been required. Although such a figure is roughly of the same order of magnitude of the value of the Hubble parameter 3.8 Ga ago HAr = 1.192H0 = 8.2 × 10−11 a−1, standard general relativity rules out cosmological explanations for the hypothesized Earth’s recession rate. Instead, a class of modified theories of gravitation with nonminimal coupling between the matter and the metric naturally predicts a secular variation of the relative distance of a localized two-body system, thus yielding a potentially viable candidate to explain the putative recession of the Earth’s orbit. Another competing mechanism of classical origin that could, in principle, allow for the desired effect is the mass loss, which either the Sun or the Earth itself may have experienced during the Archean. On the one hand, this implies that our planet should have lost 2% of its present mass in the form of eroded/evaporated hydrosphere. On the other hand, it is widely believed that the Sun could have lost mass at an enhanced rate, due to a stronger solar wind in the past for not more than ≈ 0.2–0.3 Ga.

    Full Text Available A psoríase, doença inflamatória crônica é caracterizada por lesões dérmicas sobrepostas a áreas de lesões eritematosas ou pustulares. Ocorre pela alteração no ciclo de crescimento das células epidérmicas, levando ao espessamento epidérmico decorrente da hiperproliferação celular e vascular com presença de infiltrado linfocitário. Pode desencadear manifestações como febre, mal-estar, fraqueza e outros. Seu diagnóstico é predominantemente clínico, podendo ser complementado pela biópsia das lesões. Entretanto, alguns casos encontrados na literatura e no caso que será relatado existe a presença de eosinofilia, mesmo na ausência de fatores que justificariam o surgimento desse sinal em pacientes portadores da psoríase. Objetivo: Relatar o caso de paciente encaminhado à hematologia com quadro de psoríase concomitante à eosinofilia. Relato de Caso: Paciente de 67 anos, masculino, vem encaminhado com hipótese diagnóstica de Síndrome Hipereosinofílica. Queixa de eosinofilia persistente (>1500 por mais de seis meses tendo realizado tratamento com Albendazol e Metronidazol, sem êxito. Concomitantemente, apresenta psoríase em acompanhamento da dermatologia sem sintomas sistêmicos. Exames laboratoriais: NR para Hepatite B ou C, HIV ou Toxocara canis. Ausência de população celular com imunofenótipo anômalo. Aumento do percentual de granulócitos eosinófilos. Coleta de JAK2 e BLC/ABR negativos. Tratamento da psoríase é realizado com shampoo indicado. Após dois meses, ainda apresenta eosinófilos = 1820. Conclusão: Recentemente, estabeleceu-se uma relação entre a eosinofilia e o aparecimento da psoríase. Não encontramos mais nenhuma causa possível que explique a eosinofilia deste paciente.

    Faculty and students at Queensborough Community College and Medgar Evers College of the City University of New York (CUNY) have, over several years now, employed simple software familiar to most undergraduate students to perform useful calculations, including statistical analyses, regarding various geophysical phenomena. Topics have included Space Weather, Interplanetary Magnetic Field (IMF) direction and strength fluctuations, geomagnetic and ionospheric responses to solar flares, and Coronal Mass Ejection (CME) events. Our statistical analyses have utilized second-order measures of fluctuation of the IMF strength, especially what we now call the Cheung number: the number of times that the value of Sigma-B, as provided by the ACE (Advanced Composition Explorer) data, has exceeded 0.5nT during a 6 hour interval. We have also utilized the Higuchi fractal dimension of various somewhat random fluctuations, including Sigma-B and the brightness or strength of adjacent pixels or data points in somewhat random data sequences in time or spatial dimension, including IMF fluctuations and SOHO (Solar Heliographic Observer) images of the Sun. These we have correlated with each other and with such variables as SEP (Solar Energetic Particle) peak flux, TEC (Total Electron Content) of the ionosphere, and Dst (Disturbance storm-time) in the geomagnetic field. Recent results indicate that the IMF fluctuation measures are well correlated with the SEP peak flux, the Dst, and TEC. Higuchi fractal analysis of SOHO photospheric ultraviolet brightness indicates, consistent with concomitant increased chaos or randomness of photospheric brightness, an increased likelihood of solar flare events or CME affecting interplanetary space and the earth's magnetosphere/ionosphere/atmosphere.

    We derive equations for the ASE intensity, decay time, and heat load. The crux of our development is frequency integration over the gain lineshape followed by a spatial integration over the emitters. These integrations result in a gain length that is determined from experiment. We measure the gain as a function of incident pump power for a multi-pass pumped Yb:YAG disk doped at 9.8 at.% with an anti-ASE cap. The incident pump powers are up to 3kW. Our fit to the measured gain is within 10% of the measured gain up to pump powers where the gain starts to flatten out and roll over. In this comparison we extract the gain length that turns out to be 43% of the pump spot size of 7mm.

    Full Text Available This research investigates the association between analyst coverage, ownership concentration and market liquidity in Amman Stock Exchange (ASE. Using a unique dataset about information asymmetry, several proxies related to the information asymmetry are used to clarify certain aspects of market liquidity. In a sample of 131 companies with comprehensive data collected from company guides and Datastream, information asymmetry measured by analysts’ coverage is found to be an important determinant of market liquidity. In particular, market liquidity is lower where firms have larger analysts coverage and where firms are denoted with high degree of ownership concentration. The effect of analysts coverage is, however, found to be more marked in firms with high levels of ownership concentration. The study provides theoretical and empirical improvement of market liquidity literature towards an understanding of the information asymmetry proxies in ASE. Policymakers, after the 2007-2009 scandal have formed governance codes that highlight the importance of disclosure requirements as key responsibility of financial analysts. The link between analysts coverage and market liquidity established in this research provides evidence for insider investors on the roles and potential effectiveness of analysts in carrying this responsibility.

As plantas utilizadas são: Ammi visnaga, Bergenia ligulata, Cynodon dactylon, Herniaria hirsuta e Phyllanthus niruri. A atividade antilitogênica foi relacionada às alterações da composição iônica da urina, atividade diurética, inibição de cristalização e agregação de cristais. Destaca-se o uso de Phyllanthus niruri, pela eficácia na prevenção dos urólitos. Extratos de Phyllanthus niruri normalizaram níveis altos de cálcio urinário, desfavorecendo os estágios iniciais de formação dos urólitos. Adicionalmente, foram associados à elevação da filtração glomerular e excreção urinária de ácido úrico sugerindo utilização potencial não só como efeito lítico e preventivo das calculoses, mas também em pacientes hiperuricêmicos e portadores de insuficiência renal. A partir dos resultados relatados, pode-se concluir que os trabalhos apresentados pela literatura atual são capazes de comprovar os efeitos benéficos do uso de plantas medicinais no controle de urolitíase. Entretanto, ainda são escassos os estudos realizados em animais domésticos, predominando ensaios desenvolvidos em roedores.

  8. Lead-free solder technology transfer from ASE Americas

    FTHENAKIS,V.

    1999-10-19

    To safeguard the environmental friendliness of photovoltaics, the PV industry follows a proactive, long-term environmental strategy involving a life-of-cycle approach to prevent environmental damage by its processes and products from cradle to grave. Part of this strategy is to examine substituting lead-based solder on PV modules with other solder alloys. Lead is a toxic metal that, if ingested, can damage the brain, nervous system, liver and kidneys. Lead from solder in electronic products has been found to leach out from municipal waste landfills and municipal incinerator ash was found to be high in lead also because of disposed consumer electronics and batteries. Consequently, there is a movement in Europe and Japan to ban lead altogether from use in electronic products and to restrict the movement across geographical boundaries of waste containing lead. Photovoltaic modules may contain small amounts of regulated materials, which vary from one technology to another. Environmental regulations impact the cost and complexity of dealing with end-of-life PV modules. If they were classified as hazardous according to Federal or State criteria, then special requirements for material handling, disposal, record-keeping and reporting would escalate the cost of decommissioning the modules. Fthenakis showed that several of today's x-Si modules failed the US-EPA Toxicity Characteristic Leaching Procedure (TCLP) for potential leaching of Pb in landfills and also California's standard on Total Threshold Limit Concentration (TTLC) for Pb. Consequently, such modules may be classified as hazardous waste. He highlighted potential legislation in Europe and Japan which could ban or restrict the use of lead and the efforts of the printed-circuit industries in developing Pb-free solder technologies in response to such expected legislation. Japanese firms already have introduced electronic products with Pb-free solder, and one PV manufacturer in the US, ASE Americas has used a

    2016-03-01

    In this paper, a heuristic algorithm that considers ASE (Amplified Spontaneous Emission) noise impairment is developed for demand routing in long distance optical networks. Amplifier span constraints, determined by ASE noise impairment, are presented to constrain the maximal transparent reach of a lightpath. Problem formulation and heuristic algorithms are given. Simulation demonstrates that each demand stream is guaranteed to be successfully routed, and network resources (wavelength channels and transceivers) are effectively utilized.

    Full Text Available In the years 2003-2004 two experiments: laboratory and field, were carried out to detect the level of wild oat herbicide resistance. Weeds were collected from fields in south-eastern Poland, on the basis of survey conducted between farmers who have problems with wild oat herbicidal fighting. Two herbicides were tested: fenoxaprop- P-ethyl and diclofop methyl, both ACC-ase inhibitors. The laboratory test was established by modified Letouze et al. (1997 method. After 6-day growth on each herbicide water solution, the number of alive wild oat seedlings was assesed. In the field experiment plants in 3-5 leaf stage were sprayed with field dose of each herbicide. Two weeks after spraying the percentage of plants damage and in July the percentage of flowering plants were assesed. The wild oat plants that survive in laboratory test in ≥50% and plants that flowered in ≥50% in field conditions were recognized as resistant. On that basis wild oat resistace to fenoxaprop-P-ethyl and to diclofop methyl was stated on 17% and 28% fields from overall number of 18 fields, respectively.

  4. Analytical Model for Overmodulation in EDFAs in the Presence of ASE

    Directory of Open Access Journals (Sweden)

    MohadMehdi Karkhanehchi

    2008-06-01

    Full Text Available We investigate the effect of ASE(Amplified Spontaneous Emission on the gain modulation, that also referred to overmodulation. The gain modulation is the low-frequency (kHz amplitude modulation of the EDFA pump and the communication signal used for propagating line monitoring information. We develop the model of Novak and Moesle (2002, by including ASE, that they neglected. The derivation of an analytical model, for EDFA overmodulation response, has been presented. This model provides analytical expressions for the pump and input signal overmodulation responses, respectively. These expressions describe the output signal modulation index amplitude and phase, assuming small sinusoidal steady-state oscillations of the mean pump or input signal power. In this paper we show that ASE has some effects on predictions in the high gain/low saturation regime.

    We have studied the effects of adding small amounts of Mg on the electrical and thermal properties of a-Se films. The addition of Mg in the ppm range has resulted in significant changes in the charge transport and stability. The doped samples have shown to be excellent n-like layers which have electron ranges much greater than hole ranges, {mu}{sub e}{tau}{sub e}>>{mu}{sub h}{tau}{sub h}. The n -like layers block the injection of holes from the positive electrode which results in a lower dark current in a-Se based X-ray detectors. The Differential scanning calorimetry studies have shown that a-Se doped with lower concentrations of Mg is more stable than samples with higher concentrations.

    Comentários: Neste caso, tal como referido na literatura, a presença de colelitíase comportou um risco acrescido de colédo- co-litíase sintomática. Contudo, a abordagem terapêutica não é consensual. Se por um lado na criança pequena a abordagem da litíase vesicular assenta numa atitude expectante, na presença de litíase biliar obstrutiva a terapêutica médica não é eficaz e a CPRE é o método terapêutico gold standard, mas a experiência em idade pediátrica é limitada. Neste caso, a ausência de ex- periência na realização de CPRE, nesta faixa etária, nas zonas Norte e Centro do país determinou que o procedimento se tenha realizado num Hospital de Lisboa.

    This work studies the detective quantum efficiency (DQE) of a-Se-based solid state x-ray detectors for medical imaging applications using ARTEMIS, a Monte Carlo simulation tool for modeling x-ray photon, electron and charged carrier transport in semiconductors with the presence of applied electric field. ARTEMIS is used to model the signal formation process in a-Se. The simulation model includes x-ray photon and high-energy electron interactions, and detailed electron-hole pair transport with applied detector bias taking into account drift, diffusion, Coulomb interactions, recombination and trapping. For experimental validation, the DQE performance of prototype a-Se detectors is measured following IEC Testing Standard 62220-1-3. Comparison of simulated and experimental DQE results show reasonable agreement for RQA beam qualities. Experimental validation demonstrated within 5% percentage difference between simulation and experimental DQE results for spatial frequency above 0.25 cycles/mm using uniform applied electric field for RQA beam qualities (RQA5, RQA7 and RQA9). Results include two different prototype detectors with thicknesses of 240 μm and 1 mm. ARTEMIS can be used to model the DQE of a-Se detectors as a function of x-ray energy, detector thickness, and spatial frequency. The ARTEMIS model can be used to improve understanding of the physics of x-ray interactions in a-Se and in optimization studies for the development of novel medical imaging applications. © 2017 American Association of Physicists in Medicine.

    Full Text Available FUNDAMENTOS: A pitiríase versicolor é uma infecção crônica recorrente da camada córnea causada pela Malassezia furfur, geralmente assintomática, podendo ser causa de fungemia. A síndrome da imunodeficiência adquirida caracteriza-se por uma importante depressão celular, o que propicia a ocorrência de infecções oportunistas. OBJETIVOS: Dados a imunodepressão causada pelo HIV e o risco da presença de M. furfur em sua forma patogênica no imunocomprometido, realizou-se este trabalho comparativo buscando as reais diferenças da pitiríase versicolor no imunocompetente e no imunodeprimido pelo HIV. PACIENTES E MÉTODOS: Foram avaliados, no período de julho de 1998 a junho de 1999, 50 pacientes HIV positivos do Hospital Universitário da UFJF. Como grupo controle, foram examinados de forma aleatória 50 pacientes soronegativos para HIV. Para cada paciente foi preenchido um protocolo constando de identificação e exames clínicos e laboratoriais. RESULTADOS: A pitiríase versicolor foi diagnosticada clinicamente no grupo HIV positivo em sete (14% pacientes, resultado coincidente no grupo controle. Quanto ao passado para a pitiríase versicolor, 12 (24% pacientes já haviam apresentado tal doença no grupo HIV positivo, e igual incidência ocorreu no grupo controle. CONCLUSÕES: A pitiríase versicolor não se mostrou mais freqüente e nem mais agressiva na população imunodeprimida pelo HIV em relação ao grupo controle, enquanto a dermatite seborréica apresentou-se mais freqüente no grupo infectado pelo HIV.

    Very little is known about the attitudes and views that might underlie and explain the variation in occupational disability assessment behaviour between insurance physicians. In an earlier study we presented an adjusted ASE model (Attitude, Social norm, Self-efficacy) to identify the determinants of the disability assessment behaviour among insurance physicians. The research question of this study is how Attitude, Social norm, Self-efficacy and Intention shape the behaviour that insurance physicians themselves report with regard to the process (Behaviour: process) and content of the assessment (Behaviour: assessment) while taking account of Knowledge and Barriers. This study was based on 231 questionnaires filled in by insurance physicians, resulting into 48 scales and dimension scores. The number of variables was reduced by a separate estimation of each of the theoretical ASE constructs as a latent variable in a measurement model. The saved factor scores of these latent variables were treated as observed variables when we estimated a path model with Lisrel to confirm the ASE model. We estimated latent ASE constructs for most of the assigned scales and dimensions. All could be described and interpreted. We used these constructs to build a path model that showed a good fit. Contrary to our initial expectations, we did not find direct effects for Attitude on Intention and for Intention on self reported assessment behaviour in the model. This may well have been due to the operationalization of the concept of 'Intention'. We did, however, find that Attitude had a positive direct effect on Behaviour: process and Behaviour: Assessment and that Intention had a negative direct effect on Behaviour: process.

  5. Sun-earth environment study to understand earthquake prediction

    Science.gov (United States)

    Mukherjee, S.

    2007-05-01

    Earthquake prediction is possible by looking into the location of active sunspots before it harbours energy towards earth. Earth is a restless planet the restlessness turns deadly occasionally. Of all natural hazards, earthquakes are the most feared. For centuries scientists working in seismically active regions have noted premonitory signals. Changes in thermosphere, Ionosphere, atmosphere and hydrosphere are noted before the changes in geosphere. The historical records talk of changes of the water level in wells, of strange weather, of ground-hugging fog, of unusual behaviour of animals (due to change in magnetic field of the earth) that seem to feel the approach of a major earthquake. With the advent of modern science and technology the understanding of these pre-earthquake signals has become stronger enough to develop a methodology of earthquake prediction. A correlation of earth directed coronal mass ejection (CME) from the active sunspots has been possible to develop as a precursor of the earthquake. Occasional local magnetic field and planetary indices (Kp values) changes in the lower atmosphere that is accompanied by the formation of haze and a reduction of moisture in the air. Large patches, often tens to hundreds of thousands of square kilometres in size, seen in night-time infrared satellite images where the land surface temperature seems to fluctuate rapidly. Perturbations in the ionosphere at 90 - 120 km altitude have been observed before the occurrence of earthquakes. These changes affect the transmission of radio waves and a radio black out has been observed due to CME. Another heliophysical parameter Electron flux (Eflux) has been monitored before the occurrence of the earthquakes. More than hundreds of case studies show that before the occurrence of the earthquakes the atmospheric temperature increases and suddenly drops before the occurrence of the earthquakes. These changes are being monitored by using Sun Observatory Heliospheric observatory (SOHO) satellite data. Whatever the manifestations in the environment of the atmosphere or geosphere may be, there is a positive correlation of CMEs with change in magnetic field followed by aurora borealis or sudden spark of light from the sky before an earthquake. Any change in geomorphology in the pixel level, changes in groundwater level, geochemical anomalies of soils surrounding active faults and vegetation anomalies should be monitored in the mirror image position of sunspots on the earth facing side in reference to CME from the sun.

Ten semi-structured interviews focused on health, religion and Hansen's disease, broaching the ways the two groups faced religion. In the former inmate group, the presence of institutionalized religion was noted, which served the purposes of vigilance and isolationist therapeutics. Present day Hansen's disease patients still feel the stigmatic weight of 'leprosy" in certain situations. Five questionnaires were also given to DHDS health professionals, who presented their considerations concerning the patient's religion and the treatment.

    Full Text Available In this paper, we investigate the effects of gamma (γ radiation on the spectral and mplified spontaneous emission (ASE properties of two conjugated polymers (CPs viz., poly [2-methoxy-5-(2-ethylhexyloxy-1,4-phenylenevinylene] (MEH–PPV (CPM and poly{[2-[2′,5′-bis(2″-ethylhexyloxyphenyl]-1,4-phenylenevinylene]-co-[2-methoxy-5-(2′-ethylhexyloxy-1,4-phenylene vinylene]} (BEHP-co-MEH–PPV (BMP in tetrahydrofuran (THF. Gamma irradiation strongly affected the photophysical properties of these CPs. To explore these changes, gamma radiation, in the range of 2–50 kGy, was used to maintain the temperature at 5 °C constant for all doses at a dose rate of 12.67 kGy/h, using a 60Co gamma ray. The ASE profiles of the CPs in THF were obtained under the high power excitation of a Nd:YAG laser (355 nm, pre- and post-radiation. The result revealed a dramatic blue shift of the fluorescence and the ASE spectra after gamma irradiation. This shift in the luminescence and ASE spectra could be a response to the conformational disorders such as gamma irradiation-induced polymer crosslinking, which was verified using Raman spectra, FTIR, and swelling experiments. This could be the first report on the effect of gamma radiation on the ASE properties of conjugated polymers.

The workers are those who keep the economy on track. And the workers are also the consumers, Without consumers, as every first term economy student at any university knows by now, there is no national economic growth. Therefore, the second long holiday of the year will certainly- be conducive to the economy.

    Optical aberrations induced in thin-disk laser elements with an undoped layer, performing as an anti-ASE cap, are analyzed. A numerical model, used for calculations of the optical path difference (OPD) induced by temperature distribution inside the laser element and by deformation of surfaces, was confirmed experimentally. Results of numerical modeling manifest that adding an undoped layer on the thin-disk has detrimental effect on the reflected laser beam brightness and scaling. It is also shown that brightness of a thin-disk laser may be enhanced by the use of the Gaussian pump beam profile.

    Bipolar spindle assembly requires a balance of forces where kinesin-5 produces outward pushing forces to antagonize the inward pulling forces from kinesin-14 or dynein. Accordingly, Kinesin-5 inactivation results in force imbalance leading to monopolar spindle and chromosome segregation failure. In fission yeast, force balance is restored when both kinesin-5 Cut7 and kinesin-14 Pkl1 are deleted, restoring spindle bipolarity. Here we show that the cut7Δpkl1Δ spindle is fully competent for chromosome segregation independently of motor activity, except for kinesin-6 Klp9, which is required for anaphase spindle elongation. We demonstrate that cut7Δpkl1Δ spindle bipolarity requires the microtubule antiparallel bundler PRC1/Ase1 to recruit CLASP/Cls1 to stabilize microtubules. Brownian dynamics-kinetic Monte Carlo simulations show that Ase1 and Cls1 activity are sufficient for initial bipolar spindle formation. We conclude that pushing forces generated by microtubule polymerization are sufficient to promote spindle pole separation and the assembly of bipolar spindle in the absence of molecular motors.

    Full Text Available De 1924 a 1962 o Brasil utilizou a internação compulsória de pacientes de hanseníase como controle da doença na comunidade. Com o final dessa política, muitos pacientes continuaram a viver nessas unidades. O Asilo Pirapitingui, hoje Hospital Dr. Francisco Ribeiro Arantes, é a única retaguarda asilar para internação de portadores de hanseníase por indicação social. Obtivemos o relato da história de vida de oito de seus remanescentes, que foram gravados e transcritos. A análise temática desses relatos permitiu a identificação das seguintes categorias: hanseníase; internação; vida cotidiana; a instituição; condições atuais de saúde; e permanência na instituição após a extinção da internação compulsória.From 1924 to 1962, Brazil used compulsory internment of Hansen's disease patients as one of the ways of controlling the disease in the community. After this policy ended, many patients continued to live in these units. The former Asilo Pirapitingui, now the Hospital Dr. Francisco Ribeiro Arantes, is the only old-style asylum for the socially determined internment of those suffering from Hansen's disease. Through recorded and transcribed interviews of eight of those remaining, we sought to learn their history and the meaning of this isolation in their lives. The thematic analysis of the discourse enabled identification of the following analysis categories: Hansen's disease; internment; day-to-day life; the institution; current health conditions; and staying in the institution after the end of compulsory internment.

MÉTODO: Trabalho retrospectivo de pacientes operados por complicações de ascaridíase biliar num período de cinco anos. RESULTADOS: São descritos quatro casos de ascaridíase biliar complicada em crianças (três pré escolares e um escolar, expressos através de pseudocisto pancreático, icterícia obstrutiva, colangite e múltiplos abscessos hepáticos, todos tratados cirurgicamente. Descrevemos detalhes técnicos da abordagem operatória para cada um dos casos. CONCLUSÕES: O espectro das afecções biliares secundárias à ascaridíase é variável e é necessário um arsenal de táticas operatórias para a abordagem de cada caso. É desaconselhável o uso de anti-helmínticos antes da resolução clínica da invasão da via biliar. A afecção preferencial de crianças jovens exige o uso de técnicas e materiais adequadamente delicados para a manipulação das vias biliares.

    In this article, for an optical star wavelength division multiplexing (WDM) network, with quality factor (Q-factor) as performance metric, we investigate the performance degradation due to the combined effects of four-wave mixing (FWM) and amplified spontaneous emission (ASE) noise. A mathematical model is developed, and the simulations are performed based on the optical frequency grid defined by the ITU-T Recommendation G.692. Further, the analysis is conducted for the optical fibers that are ITU-T compliant viz. G.652, G. 652D, G. 653, G. 654 and G.655. The simulation results show that, compared to the other fiber types, performance of the G. 652D and G.652 fibers is the "best", thus justifying the preferred use of fibers with high dispersion and effective area values. The simulation results also highlight that with the use of a fiber having low dispersion and effective area value, it may not be possible to obtain the desired performance.

    Full Text Available JUSTIFICATIVA E OBJETIVOS: A estrongiloidíase disseminada é uma entidade clínica relacionada a estados de imunossupressão como os que ocorrem na síndrome da imunodeficiência aguda (SIDA, nas neoplasias hematológicas e nos tratamentos imunossupressores. Sua ocorrência e gravidade são mais freqüentes em pacientes usando elevadas doses de corticosteróides. A estrongiloidíase disseminada se apresenta habitualmente sob a forma de sepse grave. Essa apresentação clínica inespecífica representa grandes desafios relacionados ao diagnóstico e tratamento, resultando em elevada taxa de mortalidade. O diagnóstico depende de elevada suspeição clínica e da identificação da larva em amostras de fluidos ou tecidos. O envolvimento cutâneo é raro, entretanto por ser característico pode incrementar a possibilidade da hipótese diagnóstica. O objetivo deste estudo foi rever na literatura os aspectos clínicos da estrongiloidíase disseminada, destacando os métodos de diagnóstico e tratamento e ressaltar a importância da suspeição clínica para a profilaxia e tratamento adequados. CONTEÚDO: Foi realizada uma busca sistemática nos últimos 30 anos através da PubMed utilizando os termos disseminated strongyloidiasis, strongyloides and hyperinfection e ivermectin. CONCLUSÕES: Recentes avanços ocorreram na área terapêutica e dentre eles destaca-se o uso da ivermectina. O seu surgimento mudou significativamente o tratamento para estrongiloidíase, no entanto a administração por via oral ou enteral desse fármaco representou importante limitação para sua utilização em pacientes com íleo ou estado de hipoperfusão tecidual. Relatos de resultados positivos com o uso de ivermectina parenteral levantaram a possibilidade de essa modalidade terapêutica ser mais eficaz nas formas graves. No entanto questões relativas à posologia e segurança ainda precisam ser elucidadas.BACKGROUND AND OBJECTIVES: Disseminated strongyloidiasis is a

Flea infestation is associated with poverty and occurs in resource-poor communities in South and Central America, the Caribbean and Sub-Saharan Africa. In Brazil, it is widespread in urban squatter settlements, villages in the rural hinterland and in traditional fishing communities along the coast. Standard therapy for tungiasis consists of removing the embedded flea with a sterile needle, and using an antibiotic agent in case of secondary infection. At present, there is no drug in the market with satisfactory clinical efficacy. We describe a case of generalized Tunga penetrans infestation that was treated with oral ivermectin.

Tanto o diagnóstico como a terapêutica adequada são, freqüentemente, difíceis de conseguir e assim podem acarretar permanente dano aos membros inferiores. Em um ano de acompanhamento, pacientes hansenianos - 10 multibacilares e 1 paucibacilar -, que foram submetidos a um protocolo clínico para o diagnóstico e classificação histopatológica, apresentaram clinicamente edema, localizado ou sistêmico. Entre estes pacientes, cinco apresentaram simultaneamente outros sintomas de reação, 4 foram classificados como reação Tipo I e um como reação tipo II. Por outro lado, três pacientes não apresentaram reação no momento do diagnóstico, mas desenvolveram alguns aspectos de reação posteriormente (2 tiveram neurite e um teve reação tipo I. Os edemas observados precedendo ou associados a quadros reacionais apresentaram ótima resposta clínica às drogas de ação anti-inflamatória (corticóide, talidomida e pentoxifilina utilizadas para o tratamento dos estados reacionais, na ausência de qualquer outro tratamento normalmente usado para edema. Embora necessitem ser confirmados por estudos controlados, estes dados sugerem fortemente que mecanismos imunológicos estejam envolvidos na fisiopatologia dos edemas na hanseníase.

    Cosmid clones containing the genes for the human and murine natural killer cell serine protease Met-ase (gene symbol GZMM; granzyme M) were identified by screening human and murine cosmid libraries with rat Met-ase (RNIK-Met-1) cDNA. The human gene has a size of 7.5 kb and an exon-intron structure identical to that of serine protease genes located on human chromosomes 5q11-q12, 14q11.2, and 19p13.3 that are expressed by lymphocytes, mast cells, or myelomonocyte precursors. Using cosmid DNA as a probe for fluorescence in situ hybridization, we identified the chromosomal position of human Met-ase as 19p13.3. Interphase studies with two differentially labeled probes for Met-ase and the azurocidin (AZU1), proteinase 3 (PRTN3), and neutrophil elastase (ELA2) gene cluster revealed that the distance of Met-ase from this gene cluster is in the range of 200 to 500 kb. Using differentially labeled mouse cosmid probes, we also mapped the murine gene for Met-ase to chromosomal band 10C, close to the gene for lamin B2. Thus, the Met-ase, AZU1, PRTN3, and ELA2 genes fall into an established region of homology between mouse chromosomal band 10C and human 19p13.3. 35 refs., 4 figs.

    The methods of accelerated solvent extraction (ASE) and supercritical fluid extraction (SFE) of polycyclic aromatic hydrocarbons (PAHs), aliphatic hydrocarbons, and chlorinated hydrocarbons from marine samples were investigated. The results of extractions of a certified sediment and four samples of suspended particulate matter (SPM) were compared to classical Soxhlet (SOX), ultrasonication (USE), and methanolic saponification extraction (MSE) methods. The recovery data, including precision and systematic deviations of each method, were evaluated statistically. It was found that recoveries and precision of ASE and SFE compared well with the other methods investigated. Using SFE, the average recoveries of PAHs in three different samples ranged from 96 to 105%, for ASE the recoveries were in the range of 97-108% compared to the reference methods. Compared to the certified values of sediment HS-6, the average recoveries of SFE and ASE were 87 and 88%, most compounds being within the limits of confidence. Also, for alkanes the average recoveries by SFE and ASE were equal to the results obtained by SOX, USE, and MSE. In the case of SFE, the recoveries were in the range 93-115%, and ASE achieved recoveries of 94-107% as compared to the other methods. For ASE and SFE, the influence of water on the extraction efficiency was examined. While the natural water content of the SPM sample (56 wt %) led to insufficient recoveries in ASE and SFE, quantitative extractions were achieved in SFE after addition of anhydrous sodium sulfate to the sample. Finally, ASE was applied to SPM-loaded filter candles whereby a mixture of n-hexane/acetone as extraction solvent allowed the simultaneous determination of PAHs, alkanes, and chlorinated hydrocarbons.

    A new technique to generate a C+L-band flat amplified spontaneous emission (ASE) source in one-stage erbium-doped fiber (EDF) using bi-directional pumping configuration is analyzed. The simulation results show that the key point of obtaining flat C+L-band ASE spectrum in one-stage EDF is using a laser diode operated at 980 nm as backward pump source. ASE source with nearly 80-nm bandwidth can be obtained by means of selecting suitable fiber length and properly adjusting the ratio of forward to backward pump power.

    The effect of spontaneous emission (ASE) noise produced by the erbium-doped fiber amplifier (EDFA) on the performance of amplified fiber loop ring-down gas sensing systems is theoretically investigated. The results show that the EDFA placed after the gas cell with a smaller ASE noise can improve the measurement accuracy. The more narrower the noise equivalent optical bandwidth of the optical band pass filter following the EDFA is, the up shift of baseline of ring-down signal can be more effectively suppressed and thus improving the measurement accuracy. It is also found the longer ring-down time can be obtained by reducing the input power due to the smaller gain fluctuations of the EDFA.

    Full Text Available The authors presented a detailed summary of the geographical distribution, clinical and pathological aspects of human pulmonary dirofilariasis. Although benign, this zoonosis, of which Dirofilaria immitis is the major etiological agent, represents a medical problem since it produces symptoms which may be confused with neoplasia and thus may subject patients to unnecessary thoracic surgery. Of 229 cases cited in the literature, only 17 were reported in Brazil, despite the existence of highly favorable conditions for the transmission of this infection in man. Thus it may well be that this parasitic infection remains underdiagnosed. Finally, the importance of a differential diagnosis between dirofilariasis and pulmonary neoplasia is emphasized in cases where there is a solitary subpleural nodule ("coin lesion" present. In addition, the development and improvement of modern immunological diagnostic techniques are essential to distinguish this benign disease from other pathological conditions and thus avoid unneccessary surgery. These techniques may reveal the true prevalence of this parasitic infection in our environment.Os autores realizaram minuciosa revisão sobre a distribuição geográfica, a clínica, a patologia e o diagnóstico da dirofilaríase pulmonar humana.

    Rhizobia in legume root nodules fix nitrogen in symbiosomes, organelle-like structures in which a membrane from the host plant surrounds the symbiotic bacteria. However, the components that transport plant-synthesized lipids to the symbiosome membrane remain unknown. This study identified and functionally characterized the Chinese milk vetch (Astragalus sinicus) lipid transfer protein AsE246, which is specifically expressed in nodules. It was found that AsE246 can bind lipids in vitro. More importantly, AsE246 can bind the plant-synthesized membrane lipid digalactosyldiacylglycerol in vivo. Immunofluorescence and immunoelectron microscopy showed that AsE246 and digalactosyldiacylglycerol localize in the symbiosome membrane and are present in infection threads. Overexpression of AsE246 resulted in increased nodule numbers; knockdown of AsE246 resulted in reduced nodule numbers, decreased lipids contents in nodules, diminished nitrogen fixation activity, and abnormal development of symbiosomes. AsE246 knockdown also resulted in fewer infection threads, nodule primordia, and nodules, while AsE246 overexpression resulted in more infection threads and nodule primordia, suggesting that AsE246 affects nodule organogenesis associated with infection thread formation. Taken together, these results indicate that AsE246 contributes to lipids transport to the symbiosome membrane, and this transport is required for effective legume-rhizobium symbiosis. PMID:24367021

    Full Text Available The replacement of conventional sample preparation techniques with newer techniques which are automated, faster and more eco-friendly, is nowadays desired in every analytical laboratory. One of the techniques with the attributes mentioned above is the Accelerated Solvent Extraction. In order to evaluate how successful this method is for the extraction of fat and organochlorine pesticides (OCPs from dried fish meat samples, we have tested two series of diverse fish using Dionex™ 350 ASE provided by Thermo Scientific™ (Germany. For a more interesting approach, we added to our investigation 7 polychlorinated biphenyl (PCBs, 3 thricholorobenzenes, 2 tetrachlorobenzenes, 1 pentachlorobenzenes and 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD. The study focused on comparing the recoveries of these analytes from different fish samples, after replacing the conventional reference method of the laboratory with ASE. The ASE parameters tested were previously used for the extraction of fat and polybrominated diphenyl ethers (PBDE from fish samples: temperature: 120 ° C; static time: 5 min; number of cycles: 3; flushing volume: 25%; rinse with nitrogen: 90 s; solvent: cyclohexane/ethyl acetate (ratio 1:1. The ASE method provided similar and in some cases better results when compared to the standard reference method, more rapidly, eco-friendly and safer. Any high or low recoveries of the analytes taken into study are attributed to random or systematic errors during the Clean-up step of the extracts and the quantification with Gas Chromatography coupled with Tandem Mass-Spectrometry (GC MS/MS.

    2017-03-01

    In this study, we present the gain and noise figure performance improvement in L-band erbium-doped fiber amplifier (L-EDFA) provided by amplified spontaneous emission (ASE) reinjection through different configurations of 1533 nm band FBGs. The experimental results are compared with a single-stage bidirectionally pumped conventional L-EDFA design. It is shown that when the forward and/or the backward ASE noise is partly reinjected to L-EDFA using a double/single 1533 nm fiber Bragg gratings (FBG), the gain and noise figure performance of L-EDFA increases depending on the FBG configuration. The best gain and NF performance in our L-EDFA was achieved by reinjection of forward and backward ASE through FBG1 and FBG2 leading to an 4.5 dB increase in gain and 1 dB decrease in NF at 1585 nm and -30 dBm input signal power. The results show that both FBGs must be used at the same time to improve gain and NF performance in L-band EDFAs.

    Full Text Available No presente artigo, os autores fazem uma revisão dos aspectos epidemiológicos da teníase e cisticercose. A cisticercose é produzida pelo desenvolvimento da forma larval da Taenia, o Cysticercus, nos tecidos, sendo transmitida pela ingestão de ovos de Taenia. A cisticercose humana e animal são consideradas um grande problema sócio-econômico em muitos países. É considerada uma zoonose endêmica, estando distribuída nos países em desenvolvimento, especialmente nas áreas rurais. A invasão da larva no sistema nervoso central em humanos constitui uma séria complicação. A cisticercose é um dos maiores problemas de saúde pública dos países em desenvolvimento e a neurocisticercose é considerada a doença parasitária mais comum do sistema nervoso humano. A conservação da carne em temperatura inferior a -15ºC durante seis dias, sua cocção adequada, além da inspeção sanitária das carnes e o diagnóstico e tratamento da teníase humana em áreas endêmicas constituem as principais medidas de controle.Is described a review of the epidemiological aspects of teniasis and cysticercosis. Cysticercosis is caused by the development of the larval form of Taenia, wich results in the Cysticercus in tissues, and is transmitted through ingestion of Taenia eggs. Human and animal cysticercosis are a great socioeconomic problem in many countries. It is a endemic zoonosis and is widespread in developing countries especially in rural areas. Larval invasion of the central nervous system constitutes a serious complication in humans. Cysticercosis is one of the great public health problems in developing countries and the neurocysticercosis is considered the most common parasitic disease of the human central nervous system. The freezing of meat for six days in temperatures below -15ºC, its adequate cooking, meat inspection and treatment individual patients infected with adult worms in endemic areas are the main control measures.

    2007-10-01

    The present paper reports the DC conductivity measurements at high electric fields in vacuum evaporated amorphous thin films of a-Se100−Sn ( = 0, 2, 4, 6) glassy alloys. Current–voltage (–) characteristics have been measured at various fixed temperatures. In these samples, at low electric fields, ohmic behaviour is observed. However, at high electric fields ( ∼ 104 V/cm), non-ohmic behaviour is observed. An analysis of the experimental data confirms the presence of space charge limited conduction (SCLC) in the glassy materials studied in the present case. From the fitting of the data to the theory of SCLC, the density of defect states (DOS) near Fermi level is calculated. Increase in DOS with increase in Sn concentration has been found which could be correlated with the electronegativity difference between the two elements used here in making the glassy alloys. The peculiar role of the element Sn as an impurity in the pure Se glassy alloy is also discussed.

    2012-03-15

    We present interactive quantum chemistry simulation at the atom superposition and electron delocalization molecular orbital (ASED-MO) level of theory. Our method is based on the divide-and-conquer (D&C) approach, which we show is accurate and efficient for this non-self-consistent semiempirical theory. The method has a linear complexity in the number of atoms, scales well with the number of cores, and has a small prefactor. The time cost is completely controllable, as all steps are performed with direct algorithms, i.e., no iterative schemes are used. We discuss the errors induced by the D&C approach, first empirically on a few examples, and then via a theoretical study of two toy models that can be analytically solved for any number of atoms. Thanks to the precision and speed of the D&C approach, we are able to demonstrate interactive quantum chemistry simulations for systems up to a few hundred atoms on a current multicore desktop computer. When drawing and editing molecular systems, interactive simulations provide immediate, intuitive feedback on chemical structures. As the number of cores on personal computers increases, and larger and larger systems can be dealt with, we believe such interactive simulations-even at lower levels of theory-should thus prove most useful to effectively understand, design and prototype molecules, devices and materials.

    Full Text Available The concept of relative purchasing power parity is applied to evaluate the exchange rates for currencies such as: the German Mark, Japanese Yen, British Poundsterling, French Franc, Swedish Krona, Italian Lira, and the Canadian Dollar against the USA dollar. Another objective of the study is to evaluate the sensitivity of consumer price indices to exchange rates for each country as well as to test for differences between atual exchange rates and their PPP predicted rates. The results show that in the long-run, actual exchange rates continually move toward the purchasing power predicted rates. On the other hand, in the short-run, the actual and parity exchange rates often experience disequilibrium. It was also found that positive changes in society's purchasing power caused positive changes in the actual exchange rates in every country except Japan. Abstract in Bahasa Indonesia : Konsep paritas daya beli relatif diterapkan untuk mengukur nilai tukar mata uang beberapa negara yaitu - Mark Jerman, Yen Jepang, Poundsterling Inggris, Franc Perancis, Krona Swedia, Lira Italia dan Dolar Kanada, terhadap Dolar Amerika. Selain itu, penelitian ini bertujuan melihat sensitivitas perubahan indeks harga konsumen terhadap perubahan nilai tukar mata uang tiap negara terhadap Dolar Amerika serta menguji apakah terdapat perbedaan secara signifikan antara nilai tukar aktual dengan nilai tukar berdasarkan konsep paritas daya belinya. Hasil penelitian ini menunjukkan bahwa dalam jangka panjang, nilai tukar aktual akan bergerak kembali mendekati nilai tukar paritas daya belinya. Sebaliknya dalam jangka pendek, nilai tukar aktual dan nilai tukar paritas daya belinya seringkali mengalami disekuilibrium. Ditemukan juga bahwa setiap perubahan positif daya beli masyarakat menyebabkan adanya perubahan positif nilai tukar aktual mata uang setiap negara, kecuali negara Jepang. Kata kunci: paritas daya beli, mata uang, kurs valuta asing

    Full Text Available A psoríase é doença inflamatória crônica, imunologicamente mediada, recorrente e de caráter universal. Aproximadamente um terço dos adultos acometidos refere início da doença antes dos 16 anos de idade. Quanto mais precoce, mais grave tende a ser a evolução do quadro. Em crianças, as lesões podem ser fisicamente desfigurantes, causando prejuízos psicológicos e evidente comprometimento da qualidade de vida. As medicações sistêmicas utilizadas na psoríase, bem como a fototerapia, têm indicação limitada na infância, devido aos efeitos cumulativos das drogas, à baixa aceitação e ao risco de teratogenicidade. Nesta seção, discutiremos as principais manifestações clínicas da psoríase na infância e na adolescência, bem como os diagnósticos diferenciais, opções terapêuticas e prognóstico.Psoriasis is a chronic, immunologically mediated, recurrent and universal inflammatory disorder. Approximately one third of adults refer onset before 16 years of age. The sooner the onset, the worse is the prognosis. In children, lesions may be physically disfiguring, leading to psychological impairment and evident loss of quality of life. Systemic therapy used in psoriasis, as well as phototherapy, has limited use in children due to accumulative effects of drugs, low acceptance, and risk of teratogenicity. In this section, we discuss the main clinical aspects of psoriasis in childhood and adolescence, differential diagnosis, therapeutic options, and prognosis.

    Full Text Available Paciente com história de 18 meses de emagrecimento e icterícia foi encaminhado ao Serviço de Cirurgia Abdominal do Hospital do Câncer, São Paulo, SP., com hipótese diagnóstica de câncer de cabeça de pâncreas. Exames laboratoriais mostraram elevação de bilirrubinas e de enzimas canaliculares. Ultra-sonografia abdominal revelou dilatação de via biliar intra e extra-hepática. Tomografia computadorizada mostrou árvore biliar dilatada com presença de cálculo de cerca de 3 cm em colédoco distal. O paciente foi submetido a colecistectomia com coledocotomia, retirada do cálculo e anastomose colédoco-duodenal por laparoscopia. Evoluiu sem intercorrências, recebendo alta no sexto dia de pós-operatório. Conclui-se que o tratamento laparoscópico da coledocolitíase é factível em alguns pacientes, especialmente naqueles com dilatação de via biliar. A retirada de cálculos deve ser seguida de procedimento de drenagem da via biliar com dreno de Kehr. Em alguns pacientes com colédoco cronicamente dilatado, como o do presente caso, a anastomose colédoco-duodenal é o procedimento de escolha.With the advances of videolaparoscopic surgery, this approach had become the treatment of choice for cholelithiasis. However, about 5% to 10% may present common bile duct lithiasis. Most surgeons have still difficulties to deal with this situation and do prefer resolve with open surgery or with further endoscopic approach. We present a case of a 60-year-old man, with 18 months history of right upper quadrant pain, weight loss and jaundice. He was referred with diagnostic of pancreatic cancer. Laboratory investigation showed increased bilirrubin (10 mg/dL, alkaline phosphatase and GGT. Abdominal ultrasound showed atrophic gallbladder with dilated intra and extrahepatic biliary tree. Computerized tomography scan disclosed enlarged biliary tree with 3 cm stone in the distal common bile duct. The patient underwent a laparoscopic cholecystectomy

    Full Text Available Por meio das representações sociais, detectamos diferentes experiências de viver a hanseníase no contexto familiar e individual de uma população constituída por 202 hansenianos (132 homens e 70 mulheres, inscritos no programa de controle e tratamento dos serviços de saúde de Ribeirão Preto. Duas etapas para coletas de informaç��es foram realizadas. Na primeira, os hansenianos responderam a um questionário com perguntas estruturadas; na segunda, foram ouvidos relatos de situações vividas no cotidiano de dez homens e mulheres. Os dados revelaram que a doença mobilizou representações diferentes entre os homens e mulheres nos diferentes grupos sociais. A hanseníase representou um desequilíbrio entre os gêneros, acentuando as desigualdades já existentes no campo sócio-cultural e criando novos problemas responsáveis pelos prejuízos bio-psico-sociais e econômicos, além dos estigmas que pesam sobre os indivíduos. Tais resultados devem reorientar os programas de controle e tratamento, visando à recuperação social dos hansenianos, e também servir de paradigma a novas investigações.

    Since lipids are depleted in {sup 13}C relative to proteins and carbohydrates, variations in lipid composition among species and within individuals significantly influence {delta}{sup 13}C and may result in misleading ecological interpretations. Whereas lipid extraction before IRMS analysis constitutes a way of stable isotope result lipid-normalisation, such a procedure was given up because of the un-controlled effects of the methods used (i.e., 'Bligh and Dyer', Soxhlet, etc.) on {delta}{sup 15}N. The aim of this work was to develop a simple, rapid and efficient lipid extraction method allowing for simultaneous C and N stable isotope analysis in the biological soft tissues of aquatic organisms. The goal was to be free from the lipid influence on {delta}{sup 13}C values without interfering with {delta}{sup 15}N values. For that purpose, the modern automated pressurized liquid extraction technique ASE (accelerated solvent extraction) was selected. Eel muscles representative of a broad range of fat contents were extracted via ASE by using different semi-polar solvents (100% dichloromethane and 80% n-hexane/20% acetone) and by operating at different temperature (ambient temperature and 100 deg. C) and pressure (750 and 1900 psi) conditions. The results were discussed in terms of lipid extraction efficiency as well as {delta}{sup 13}C and {delta}{sup 15}N variability.

    Full Text Available Médica, doutora em patologia, Euzenir Sarno é estudiosa da imunopatologia da hanseníase, infecção crônica das mais antigas que constitui uma doença exclusivamente humana. Integrante de um dos ambulatórios de referência sobre a doença no Brasil, no qual são diagnosticados de 220 a 250 pacientes novos/ano, ressalta que uma das conseqüências da impossibilidade de se cultivar o Mycobacterium leprae é a permanência das mesmas questões seculares a respeito da transmissão e a suscetibilidade à doença. Há, também, muitas interrogações no terreno epidemiológico que permanecem sem resposta. Estima-se que entre as pessoas que mantêm contato com pacientes multibacilares, 90% são infectados mas apenas 8% mais ou menos ficam doentes. O índice elevado de infecção de quem convive com doentes multibacilares, sem que a doença se manifeste, indica que apenas um pequeno número de indivíduos não tem resistência ao Mycobacterium leprae. Essa é uma das questões que a imunologia não consegue responder: por que algumas pessoas têm resistência e outras não. A proporção é menor se o contato ocorrer com pacientes paucibacilares, uma forma de manifestação com poucos bacilos. A hanseníase é conhecida como uma doença dermatológica, mas a especialista destaca que a primeira lesão é anestésica: o nervo é atingido. Além dos nervos sensitivos da pele, há danos que determinam lesões motoras e deformidades irreversíveis, que levam à amputação de extremidades. O Mycobacterium leprae foi uma das primeiras bactérias patogênicas que tiveram o genoma completamente seqüenciado, em 2000. Agora é que se está começando a ter realmente condições para obter testes mais precisos. A doença não é hereditária e apenas em 1986 os serviços de saúde no Brasil passaram a se organizar para combatê-la, pois durante os vinte anos de ditadura militar o sistema foi desmantelado. Em 1991, o tratamento de um ano que inclui tr

    Full Text Available RACIONAL: O tratamento da coledocolitíase continua controverso, podendo ser realizado por pancreatocolangiografia retrógrada endoscópica pré-operatória seguida de videolaparocolecistectomia ou por videolaparocolecistectomia com exploração de vias biliares. Há relato na literatura de taxa de insucesso da pancreatocolangiografia retrógrada endoscópica pré-operatória em torno de 6%. OBJETIVO: Apresentar caso de uma paciente que necessitou da realização de CPRE intra-operatória para resolução de coledocolitíase tratada sem êxito por CPRE. RELATO DO CASO: Paciente de 45 anos, admitida na emergência com quadro de dor abdominal em epigástrio e hipocôndrio direito. A ultra-sonografia da admissão evidenciou coledocolitíase, sendo ela encaminhada para pancreatocolangiografia retrógrada endoscópica pré-operatória onde não houve sucesso na cateterização da papila. Foi optado então pela realização de videolaparocolecistectomia com exploração de via biliar por pancreatocolangiografia retrógrada endoscópica pré-operatória intra-operatoria com a cateterização da papila direcionada por fio guia passado pelo ducto cístico. Foi realizada duodenoscopia com captura do fio guia que serviu para a passagem do papilótomo dando seqüência à pancreatocolangiografia retrógrada endoscópica pré-operatória e retirada dos cálculos. A paciente evoluiu satisfatoriamente tendo alta no 2º dia do pós-operatório. CONCLUSÃO: A abordagem da coledocolitíase por pancreatocolangiografia retrógrada endoscópica intra-operatória seguida de videolaparocolecistectomia, mostrou-se segura e eficaz.BACKGROUND:Choledocholithiasis treatment is still a controversial topic, being done either with endoscopic retrograde cholangiopancreatography before laparoscopic cholecystectomy or by the use of laparoscopic cholecystectomy and exploration of common bile duct.

    Full Text Available The authors describe a case of abdominal angiostrongyliasis in an adult patient presenting acute abdominal pain caused by jejunal perforation. The case was unusual, as this affliction habitually involves the terminal ileum, appendix, cecum or ascending colon. The disease is caused by the nematode Angiostrongylus costaricensis, whose definitive hosts are forest rodents while snails and slugs are its intermediate hosts. Infection in humans is accidental and occurs via the ingestion of snail or slug mucoid secretions found on vegetables, or by direct contact with the mucus. Abdominal angiostrongyliasis is clinically characterized by prolonged fever, anorexia, abdominal pain in the right-lower quadrant, and peripheral blood eosinophilia. Although usually of a benign nature, its course may evolve to more complicated forms such as intestinal obstruction or perforation likely to require a surgical approach. Currently, no efficient medication for the treatment of abdominal angiostrongyliasis is known to be available. In this study, the authors provide a review on the subject, considering its etiopathogeny, clinical picture, diagnosis and treatment.Os autores descrevem caso de angiostrongilíase abdominal em doente adulto que se manifestou como abdômen agudo devido à perfuração de alça jejunal, evento raro, uma vez que esta afecção geralmente envolve o íleo terminal, apêndice, ceco ou cólon ascendente. A doença é causada pelo nematódeo Angiostrongylus costaricensis cujos hospedeiros definitivos são roedores silvestres e os hospedeiros intermediários são caracóis e caramujos. A infecção em humanos é acidental e ocorre pela ingestão de secreção mucóide destes invertebrados presentes em vegetais ou por contato direto com o muco. A angiostrongilíase abdominal é clinicamente caracterizada pela presença de febre prolongada, anorexia, dor no quadrante inferior direito do abdômen e eosinofilia periférica. Embora a doença seja de

    Full Text Available Multidrug therapy (MDT, with rifampicin, dapsone, and clofazimine, treats leprosy infection but is insufficient in arresting or preventing the nerve damage that causes impairments and disabilities. This case-series study evaluates the benefits of the combined use of steroids and MDT in preventing nerve damage in patients with pure neural leprosy (PNL. In addition to MDT, 24 patients (88% male aged 20-79 years, median=41 received a daily morning dose of 60 mg prednisone (PDN that was gradually reduced by 10 mg during each of the following 5 months. PNL was clinically diagnosed and confirmed by nerve histopathology or PCR. A low prevalence (8.3% of reaction was observed after release from treatment. However, most of the clinical parameters showed significant improvement; and a reduction of nerve conduction block was observed in 42% of the patients. The administration of full-dose PDN improved the clinical and electrophysiological condition of the PNL patients, contributing to the prevention of further neurological damage.A poliquimioterapia (PQT, com rifampicina, dapsona, e clofazimina, trata a infecção na hanseníase, mas é insuficiente para interromper ou prevenir o comprometimento neurológico que causa as incapacidades e desabilidades, nesta enfermidade.

    Full Text Available Esse artigo analisa como que a prática do isolamento compulsório dos pacientes de hanseníase no Estado de São Paulo contribuiu para que o estigma da hanseníase atingisse pessoas que nunca portaram a doença, como foi o caso das crianças sadias filhas de portadores de hanseníase. Discute como que os ideais eugênicos contribuíram para a formação de uma postura médica que, mesmo a revelia dos progressos científicos e das recomendações internacionais, perpetuaram medidas de discriminação e segregação dessas crianças. Demonstra como estas acabaram por se tornar portadoras de um "estigma congênito" que as acompanharia por toda a vida e como isto resultou na diminuição de possibilidades de vida, obrigando-as a esconder sua situação de internas ou egressas de Preventório se quisessem competir em igualdade de condições quando da procura de emprego ou no estabelecimento de relações sociais. Analisa ainda a vida dentro dos Preventórios, a separação da família e o quotidiano de centenas de vidas moldadas dentro de estruturas de controle, nas quais a violência e o arbítrio se faziam em nome de uma visão distorcida de profilaxia.This work analyses how the compulsory isolation practice of Hansen's disease patients in the State of São Paulo has contributed for the Hansen's stigma affecting people that never had the disease - the case of healthy children of Hansen's disease carriers.

    Full Text Available Reflective semiconductor optical amplifier fiber cavity lasers (RSOA-FCLs are appealing, colorless, self-seeded, self-tuning and cost-efficient upstream transmitters. They are of interest for wavelength division multiplexed passive optical networks (WDM-PONs based links. In this paper, we compare RSOA-FCLs with alternative colorless sources, namely the amplified spontaneous emission (ASE spectrum-sliced and the externally seeded RSOAs. We compare the differences in output power, signal-to-noise ratio (SNR, relative intensity noise (RIN, frequency response and transmission characteristics of these three sources. It is shown that an RSOA-FCL offers a higher output power over an ASE spectrum-sliced source with SNR, RIN and frequency response characteristics halfway between an ASE spectrum-sliced and a more expensive externally seeded RSOA. The results show that the RSOA-FCL is a cost-efficient WDM-PON upstream source, borrowing simplicity and cost-efficiency from ASE spectrum slicing with characteristics that are, in many instances, good enough to perform short-haul transmission. To substantiate our statement and to quantitatively compare the potential of the three schemes, we perform data transmission experiments at 5 and 10 Gbit/s.

    Previously, we reported that active vitamin D deficiency in mice causes secondary hypertension and cardiac dysfunction, but the underlying mechanism remains largely unknown. To clarify whether exogenous active vitamin D rescues hypertension by normalizing the altered central renin-angiotensin system (RAS) via an antioxidative stress mechanism, 1-alpha-hydroxylase [1α(OH)ase] knockout mice [1α(OH)ase(-/-)] and their wild-type littermates were fed a normal diet alone or with 1,25-dihydroxyvitamin D3 [1,25(OH)2D3], or a high-calcium, high-phosphorus "rescue" diet with or without antioxidant N-acetyl-l-cysteine (NAC) supplementation for 4 weeks. Compared with their wild-type littermates, 1α(OH)ase(-/-)mice had high mean arterial pressure, increased levels of renin, angiotensin II (Ang II), and Ang II type 1 receptor, and increased malondialdehyde levels, but decreased anti-peroxiredoxin I and IV proteins and the antioxidative genes glutathione reductase (Gsr) and glutathione peroxidase 4 (Gpx4) in the brain samples. Except Ang II type 1 receptor, these pathophysiological changes were rescued by exogenous 1,25(OH)2D3 or NAC plus rescue diet, but not by rescue diet alone. We conclude that 1,25(OH)2D3 normalizes the altered central RAS in 1α(OH)ase(-/-)mice, at least partially, through a central antioxidative mechanism.

    Full Text Available Whether parapsoriasis represents an early stage of T-cell cutaneous lymphoma is still the subject of controversy. We evaluated the efficacy of phototherapy in the treatment of parapsoriasis and its relation with TCCL. Patients diagnosed with parapsoriasis and treated with phototherapy PUVA or UVB-NB were selected. Between 1 to 8 years following treatment the evolution of their disease was evaluated. In 62 patients the cure rate was 79.3% and 17.2% showed improvement of the lesions. Only two patients developed full blown T-cell cutaneous lymphoma. Phototherapy is an excellent treatment for parapsoriasis, with high cure rates, regardless of the type of phototherapy employed. Of the 62 patients under study, parapsoriasis showed no general tendency to progress to T-cell cutaneous lymphoma.Há controvérsias se parapsoríase pode evoluir para linfoma Cutâneo de Células T.

    Full Text Available BACKGROUND: Leprosy, an infectious disease caused by Mycobacterium leprae, can affect the skin and the peripheral nervous system and, depending on the level of involvement, it can lead to severe deformities. Leprosy is classified into two major groups: paucibacillary (up to five lesions and multibacillary (more than five lesions. The deformities that appear during the progress of the disease can affect the quality of life. OBJECTIVE: To assess quality of life of patients with paucibacillary leprosy diagnosed and treated early in the outpatients' clinic. METHODS: The Dermatology Life Quality Index questionnaire and ShortForm36 were applied to 49 outpatients undergoing treatment at the Leprosy Multidisciplinary Group of the Hospital das Clínicas of the Faculdade de Medicina of the Universidade de São Paulo. RESULTS: The majority of the patients (63% did not show impairment of the quality of life, according to the results obtained by the Dermatology Life Quality Index questionnaire. In the questionnaire Short Form-36, the scores assessed showed slight impairment of the quality of life. CONCLUSION: On this study, we can conclude that this group of patients, with paucibacillary leprosy, did not show important impairment of the quality of life. Therefore we can conclude that the earlier the diagnosis and the treatment the lesser the influence on the quality of life.FUNDAMENTOS: A hanseníase, doença infecciosa causada pelo Mycobacterium leprae, pode acometer a pele e o sistema nervoso periférico e de acordo com o grau de acometimento, levar a graves deformidades.

    Maji, Partha Sona

    2014-01-01

    In this article, silica based triangular lattice PCF has been investigated towards both narrowband and broadband dispersion compensation for application in the communication wavelength. A dual core structure is obtained by introducing two different air-hole diameters in the cladding of the PCF. Dependence of individual structural parameters towards high negative dispersion (both narrowband and broadband) has been investigated in details with multipole mode based solver. The numerical investigation exhibits narrowband of very large negative dispersion of -37,300 ps/nm/km around the wavelength of 1550 nm. Present investigation also reports broadband dispersion values varying from -800 ps/nm/km to -2600 ps/nm/km over a 200 nm wavelength (1400 nm to 1600 nm) range, and kappa values near 300 nm, which matches well with standard single mode fiber. Using the principle of power transfer from the inner core to the outer core after the coupling wavelength, we have investigated possible design of ASE suppressed amplifie...

    A new type of gain flattening filter for amplified spontaneous emission (ASE) source based on erbium doped fiber (EDF) is proposed and demonstrated by fabricating and writing two series ultra-long period fiber grating (ULPFG) on single mode fiber (SMF-28). The novelty method in this research is based on writing the two ULPFGs as fat gratings. The LPG is written by a simple and available arc-discharge method. The pump power based on single-pass backward pump configuration is around 100 mW, and the average wavelength is near to 974 nm. The gain flattening profile is obtained by 3.4 (±1.7) dB ripple in the wavelength range between 1524 nm and 1565 nm with 41-nm band width.

    本文对加速溶剂萃取仪(ASE300)和快速索氏抽提仪提取的氯仿沥青“A”及由其分离出的饱和烃、芳烃、胶质和沥青质组分做了详细对比.结果表明:多数情况下ASE300抽提出的氯仿沥青“A”的量比快速索氏抽提仪抽提出的量略多,主要是胶质和沥青质量的增加;不同抽提装置得到的饱和烃和芳烃组分的色谱-质谱谱图高度一致,定量结果的相对偏差在5%以内.各组分的稳定碳同位素分析精度±0.5‰.所有的地化参数表明ASE300完全可以替代快速索氏抽提仪,从而降低消耗、提高分析效率.%Two groups of chloroform bitumen "A" samples were separated from some selected sedimentary rock samples using an accelerated solvent extraction apparatus (ASE300) and a fast Soxhlet extraction apparatus, respectively. The geochemical parameters of saturated hydrocarbons, aromatics, resin and asphaltene from the different chloroform bitumen "A" sample groups were systematically studied and compared. The experiment results showed that the obtained amounts of chloroform bitumen "A" are slightly higher using the ASE300 than using the fast Soxhlet in most cases, and that the main increments of using ASE300 are resin and asphaltene. GC-MS study indicated that saturated and aromatic hydrocarbons extracted from two groups of chloroform bitumen "A" samples are highly consistent, the deviations of the quantitative results are less than 5 % , the differences of measured carbon stable isotope compositions for any identical component obtained respectively from two extraction methods fall into the range of ± 0. 5‰. These results indicated that ASE300 and fast Soxhlet extracted instruments are comparative. Therefore, the ASE300, the relatively consumption saving and analytically efficient method, can replace the fast Soxhlet extraction apparatus in geochemical pretreatment experiments.

    Full Text Available OBJETIVO: Miíase é a invasão de tecido humano pela larva de uma mosca da ordem Díptera. O envolvimento ocular não é comum. Lesões do aparelho lacrimal geralmente estão associadas a traumas e raramente são devidas a infestações parasitárias. O objetivo deste trabalho é relatar um caso de laceração canalicular causado por larva de Dermatobia hominis. DESCRIÇÃO: Criança do sexo feminino, 8 anos de idade, apresentou-se com celulite pré-septal não responsiva a antibioticoterapia. Foi observada uma larva de D. hominis no saco lacrimal. Realizou-se a extração cirúrgica da larva e observou-se lesão do sistema de drenagem lacrimal. COMENTÁRIOS: A infestação parasitária em via lacrimal é rara. A extração cirúrgica da larva é recomendada como tratamento de escolha. Apesar de incomum, a oftalmomiíase deve ser considerada como um diagnóstico diferencial possível em celulites não responsivas ao tratamento convencional, especialmente em áreas endêmicas. Esta é a primeira descrição de lesão do sistema de drenagem lacrimal por larva de D. hominis.OBJECTIVE: Myiasis is the invasion of human tissues by Diptera larvae. Ocular involvement is uncommon. Trauma is the major cause of lacrimal apparatus lesions. However, it is rarely associated with parasitic infestation. The objective of this paper is to report a case of canalicular laceration caused by Dermatobia hominis larva. DESCRIPTION: An eight-year-old girl presented preseptal cellulitis that was refractive to antibiotics. A Dermatobia hominis larva was observed inside the lacrimal sac. Surgical extraction was performed and laceration of the lacrimal drainage system was noted. COMMENTS: Parasitic infection of the lacrimal apparatus is rare. Surgical extraction is the treatment of choice in such cases. Despite being uncommon, ophthalmomyiasis should be considered as a possible diagnosis when cellulitis is not responsive to antibiotics, especially in endemic areas. This is

    1985-02-01

    Full Text Available Duas semanas após o insucesso da terapêutica com mebendazol — 400 mg diários durante quatro dias consecutivos —, 101 indivíduos de uma comunidade semifechada, 50,5% infectados por Hymenolepis nana, em sua maioria crianças entre dois e seis anos de idade, foram tratados com praziquantel (* em duas doses orais de 20 a 25 mg/kg, administradas com dez dias de intervalo. O diagnóstico da himenolepíase, bem como os controles de cura parasitológica realizados nos 7.º, 14.°, 21°, 30.°, 60.° e 90.° dias depois da administração da segunda dose de praziquantel, basearam-se em exames de fezes pelo método quantitativo de KATO/KATZ. A tolerância ao medicamento foi excelente e a negativação dos exames ocorreu independentemente da intensidade do parasitismo. Nos 7.° e 14° dias pós-tratamento encontraram-se ovos de H. nana, respectivamente em nove e em dois pacientes, mas esses ovos apresentavam-se distorcidos. No controle do 21.° dia todos os resultados mostraram-se negativos, traduzindo um índice de cura de 100%. A partir do 30.° dia verificou-se em três crianças a eliminação de ovos normais do parasita. Tendo em vista serem essas as únicas que viviam em regime de semi-internação nessa comunidade e a positividade tardia dos exames, esses casos foram considerados como reinfecção. Conclui-se, pelos resultados alcançados, que o esquema posológico empregado, fundamentado nas investigações experimentais conduzidas por CAMPOS & col. (1983, é eficaz e seguro para o tratamento da himenolepíase, em especial, quando se pretende tentar erradicá-la numa comunidade fechada.

    Purpose: To assess and quantify the image quality at two dose levels for an amorphous Silicon (a:Si) Cesium Iodide (CsI) flat panel system compared with a direct amorphous Selenium (a:Se) digital radiography system. Material and Methods: A contrast detectability test was performed employing the CDRAD-phantom at mAs-values leading to approximately equal phantom entrance doses of 41.4, 57.9, 75.1 and 120.8 {mu}Gy for the a:Se and 39.9, 58.4, 75.6 and 117.9 {mu}Gy for the CsI system. Images were presented to 4 independent observers. For quantitative comparison, the image quality figure (IQF) was calculated. Statistical analysis was performed using Pearson's correlation and the Wilcoxon test. A ROC-analysis was performed employing the TRG-phantom in a high- and a low-dose setting leading to entrance doses of 126.2 and 35 {mu}Gy for the direct, and 125.9 and 34.4 {mu}Gy for the indirect system. Statistical significance was evaluated using the Wilcoxon test. Results: The flat panel a:Si digital system provided superior results compared with the a:Se drum digital system with respect to low-dose settings for CDRAD-phantom and ROC-analysis, ensuring a better image quality with respect to contrast and detail detectability. Higher-dose settings provided similar results for both systems. Conclusion: Image quality of a:Si flat panel digital radiography proved to be superior to a:Se drum digital radiography using low-dose settings. If the primary target is dose reduction indirect flat panel technology should be used. Digital radiography amorphous selenium amorphous silicon chest radiography.

  5. A knowledge discovery approach to explore some Sun/Earth's climate relationships

    Science.gov (United States)

    Pou, A.; Valdes, J.

    2009-09-01

    Recent developments in data driven modeling and analysis including computational intelligence techniques may throw new light on the exploration of possible solar activity/Earth's climate relationships. Here we present three different examples of methodologies under development and some preliminary results. a) Multivariate Time Series Model Mining (MVTSMM) analysis [1] and Genetic Programming were applied to Greenland's CRETE Site-E ice core Delta O18/16 values (1721-1983, one year interval sampling) and with sunspots activity (International Sunspots Number) during the same time span [2]. According to the results (1771 to 1933 period) indicated by the lag importance spectrum obtained with MVTSMM analysis, the sun's activity itself shows high internal variability and is inhomogeneous. The Dalton minimum, a low activity period usually considered to occur between 1790 and 1830, is shown to be a complex structure beginning about 1778 and ending in 1840. Apparently, the system entered a new state in 1912. In the joint analysis, the analytical tool uses extensively the solar activity data to explain the Delta O18/16 data, showing areas of stable patterns, lag drifts and abrupt pattern disruptions, indicating changes of state in the solar processes of several kinds at different times. b) A similar MVTSMM analysis was conducted on Central England Temperature (CET) and solar activity data using Group Sunspots Number (GSN) with a useful interpretive span of time from 1771 to 1916. The joint analysis involved large amounts of solar activity variables, except for the 1843-1862 and 1877-1889 periods where the discovered models used much less information from GSN data. As with the Crete-E/ISN analysis the lag importance spectrum of CET/GSN shows a number of clear discontinuities. A quarter of them are present in both (1778-1779, 1806, 1860-1862, 1912-1913). These experiments were designed for testing methodologies and not for specific hypothesis testing. However, it seems that Delta O18/16 data would more readily respond to solar influences. This raises the suspicion that perhaps they do not only reflect temperatures but also solar activity, as well as other possible factors not directly related to atmospheric temperatures. These methodologies may be useful as exploratory tools, directing the attention to specific areas where further research should be required. This could be the case of the Delta O18/16 data, frequently considered to be a reliable and accurate proxy of temperatures. c) Another experiment was made using daily maximum temperatures from 10 Spanish meteorological stations for the period 1901-2005 [3]. Using a hybrid procedure (Differential Evolution and Fletcher-Reeves Classical Optimization) it was found that a subset was capable of preserving the 10-dimensional similarity when nonlinearly mapped into 1D. A daily index, F1 was applied to the whole dataset and grouped by years and transformed into a Kolmogorov-Smirnov dissimilarity matrix, space optimized and clustered giving the following landmarks: 1911-12, 1919-1920, 1960, 1973 and 1989. A visual comparison with the aa geomagnetic index may suggest a certain coupling with changes in the magnetic field behavior. The complexity of the patterns suggest that the possible relationships between Earth's climate and solar activity may occur in much more complex ways than just irradiance variations and simple linear correlations.

    In a world of warmth and light and living things we soon forget that we are surrounded by a vast universe that is cold and dark and deadly dangerous, just beyond our door. On a starry night, when we look out into the darkness that lies around us, the view can be misleading in yet another way: for the brightness and sheer number of stars, and their chance groupings into familiar constellations, make them seem much nearer to each other, and to us, that in truth they are. And every one of them--each twinkling, like a diamond in the sky--is a white-hot sun, much like our own. The nearest stars in our own galaxy--the Milky Way-- are more than a million times further away from us than our star, the Sun. We could make a telephone call to the Moon and expect to wait but a few seconds between pieces of a conversation, or but a few hours in calling any planet in our solar system.

    One persistent difficulty many introductory astronomy students face is the lack of a 3-dimensional mental model of the Earth-Moon system. Students without such a mental model can have a very hard time conceptualizing the geometric relationships that cause the cycle of lunar phases. The GeoWall is a recently developed and affordable projection mechanism for three-dimensional stereo visualization which is becoming a popular tool in classrooms and research labs. We present results from a study using a 3-D GeoWall with a simulated sunlit Earth-Moon system on undergraduate students' ability to understand the origins of lunar phases. We test students exposed to only in-class instruction, some with a laboratory exercise using the GeoWall Earth-Moon simulation, some students who were exposed to both, and some with an alternate activity involving lunar observations. Students are given pre and post tests using the a diagnostic test called the Lunar Phase Concept Inventory (LPCI). We discuss the effectiveness of this technology as a teaching tool for lunar phases.

    Over the last decade, it has become increasingly clear that science can be an important way to excite children about reading, writing and the arts. The natural beauty that science represents inspires students to both think about the world around them and strive to find the words and images that communicate their excitement. Colorado Lights is a new program that provides a set of five activities for students in Grades 3 through 5 to explore the beauty, science and mythology of the aurora creatively through art and writing. This standards-based, flexible 'plug-and-play' program is based on the latest research on bringing science into the literacy and art classroom. It can be used as a complete sequence of lessons or can be used as guidelines for teachers to develop their own activities.

    A method for simultaneous determination of arsanilic, nitarsone and roxarsone (ROX) residues in foods of animal origin was developed by accelerated solvent extraction-liquid chromatography-atomic fluorescence spectrometry (ASE-LC-AFS). The ultrasound centrifugation extraction and accelerated solvent extraction were compared, and the accelerated solvent extraction conditions, namely the proportion of the extraction solvent, the extraction temperature, extraction time and extraction times, were optimized. The operating conditions of LC-AFS and the mobile phase were optimized. Under the optimal conditions, the calibration curves for ASA , NIT and ROX were linear over the concentration range of 0-2.0 mg x L(-1) and their correlation coefficients were 0.999 2-0.999 8. The detection limits of ASA, NIT and ROX were 2.4, 7.4 and 4.1 microg x L(-1) respectively. The average recoveries of ASA, NIT and ROX from two samples spiked at three levels of 0.5, 2, 5 mg x kg(-1) were in the ranges of 87.1%-93.2%, 85.2%-93.9%, and 84.2%-93.7% with RSDs of 1.4%-4.6%, 1.2%-4.2%, and 1.1%-4.5%, respectively. This method possesses the merits of convenience and good repeatability, and is a feasible method for analysis of ASA, NIT and ROX in foods of animal origin.

    To increase the detection performance of breast cancers in mammograms, we need to improve shape delineation of micro calcifications and tumors. We accomplished this by developing a direct-conversion mammography system with an optical reading method and a new dual a-Se layer detector. The system achieved both small pixel size (50 micrometer) and a high Detective Quantum Efficiency (DQE) realized by 100 % of fill factor and noise reduction. We evaluated image quality performance and determined the best exposure conditions. We measured DQE and Modulation Transfer Function(MTF) according to the IEC62220-1-2. High DQE was maintained at a low radiation dosage, indicating that the optical reading method accompanies low noises. Response of MTF was maintained at up to the Nyquist frequency of 10 cyc/mm, which corresponds to 50 micrometer pixel size. To determine the best exposure conditions, we measured Contrast to Noise Ratio (CNR) and visually evaluated images of a resected breast under conditions of MoMo, MoRh, and WRh. There were occasional disagreements between the exposure conditions for achieving the maximum CNR and those for the best image graded by the visual evaluation. This was probably because CNR measurement does not measure effects of scattered X-ray. The images verified the improvement in detection and delineation performance of micro calcifications and tumors.

    Large area, real-time, amorphous selenium (a-Se) based Flat Panel Detectors (FPD) were recently equipped with low noise front end electronics. In full resolution, 14"x14" detectors (FPD14) and 9"x9" detectors (FPD9) show an electronic noise of 1400 electrons. To evaluate the positive impact of such low noise on image quality, a dedicated report on spatial characteristics (MTF, NPS and DQE) covering the low dose range from 0.6 μR to 12 μR per frame, will be presented in the first section of this paper. For one RQA5 beam quality, DQE corrected for lag extrapolated at zero spatial frequency was equal to 0.6 for quantum noise limited exposure and equal to 0.4 for 0.6 μR. Almost no difference was found between 1x1 and 2x2 resolution mode giving the opportunity to 1x1 fluoroscopy. Recent advances to reduce image temporal artifacts such as lag and ghost will make the second part of this paper. It is demonstrated that the most significant contribution to detector lag is coming from the PIN selenium structure. Above electric field of 10 V/μm charges release from traps following one x-ray exposure could not explain selenium lag. Active ghost correction based on deep trapped charge recombination was developed giving good preliminary results in showing no residual ghost for a high dose rate of 33 mR/min.

    Although the monograph Progress in Optimization I: Contributions from Aus­ tralasia grew from the idea of publishing a proceedings of the Fourth Optimiza­ tion Day, held in July 1997 at the Royal Melbourne Institute of Technology, the focus soon changed to a refereed volume in optimization. The intention is to publish a similar book annually, following each Optimization Day. The idea of having an annual Optimization Day was conceived by Barney Glover; the first of these Optimization Days was held in 1994 at the University of Ballarat. Barney hoped that such a yearly event would bring together the many, but widely dispersed, researchers in Australia who were publishing in optimization and related areas such as control. The first Optimization Day event was followed by similar conferences at The University of New South Wales (1995), The University of Melbourne (1996), the Royal Melbourne Institute of Technology (1997), and The University of Western Australia (1998). The 1999 conference will return to Ballarat ...

    Full Text Available A candidíase recorrente cutânea ou mucosa é caracterizada pela ocorrência de, no mínimo, 4 episódios de candidíase no período de um ano. Não são conhecidos os fatores que levam à recorrência desta infecção. O presente estudo avaliou a resposta linfoproliferativa e a produção de IFN-g de pacientes com candidíase recorrente. Os índices de estimulação da resposta linfoproliferativa em culturas de células de pacientes com candidíase recorrente estimuladas com antígeno de Candida albicans, PPD e TT foram respectivamente de 6±8, 17±20 e 65±30. A adição de anticorpo monoclonal anti-IL-10 às culturas de células de 6 pacientes aumentou a resposta linfoproliferativa de 735±415 para 4143±1746 cpm. A produção de IFN-g em culturas de células estimuladas com antígeno de Candida, foi 162±345pg/ml. Pacientes com candidíase recorrente apresentam uma deficiência na resposta linfoproliferativa e na produção de IFN-g, podendo a resposta imune celular ao antígeno de Candida ser restaurada parcialmente através da neutralização da IL-10 in vitro.Recurrent cutaneous or mucosal candidiasis is characterized by the occurrence of at least four candidiasis episodes within a one-year period. The factors involved in recurrence of infection are still unknown. In the present study the lymphoproliferative response and the IFN-g production by candidiasis patients were evaluated. The stimulation index of mononuclear cell cultures of candidiasis patients stimulated with Candida albicans antigen, PPD and TT were 6±8, 17±20 and 65±30, respectively.

    Full Text Available Tetanus is a serious, potentially life-threatening infectious disease, occurrence of which is limited to post-vaccination immunity and develops as a result of Clostridium tetani spores penetration into the wound. This pathogen produces one of the strongest toxins, tetanospasmin, that causes clinical manifestations. The most common symptoms are lockjaw, dysphagia, sardonic smile and tetanic seizures with tonic tension of the muscles. Death usually occurs as a result of respiratory or cardiac failure. Treatment is usually performed in the intensive care departments to avoid development of potential complications that are life-threatening. This article clearly shows the clinical case of tetanus in unvaccinated 6-year-old child with favorable outcome. The disease duration was 64 days. Targeting primary care physicians to provide immunization to risk groups will help to prevent tetanus.

Ao discorrer sobre o engajamento do Brasil no programa lançado pela Organização Mundial de Saúde, Tadiana explica que o objetivo da OMS é eliminar a hanseníase até 2005. No entanto, ela diz que a meta brasileira é, neste prazo, reduzir a incidência da doença a até menos de um caso por dez mil pessoas. Em nosso país, a estrutura e organização de tal programa, que engloba desde a formação e especialização de profissionais para garantir o diagnóstico precoce, ao acompanhamento do paciente durante o tratamento, é realizado pelo Sistema Único de Saúde (SUS, implantado em todos os estados da federação. O tratamento poliquimioterápico dura, em média, um ano, se for seguido à risca. Em muitos casos, a doença volta a se manifestar posteriormente. Ela comenta as diferenças de incidência da hanseníase, dependendo da região: já foi eliminada em dois dos três estados do Sul do país, ao passo que em estados do Norte e Centro-Oeste atinge índices hiperendêmicos.

    Leveduras do gênero Candida têm sido freqüentemente isoladas de animais domésticos e silvestres, entretanto, candidíase não tem sido reportada em primatas. Encaminhou-se à Faculdade de Veterinária, Departamento de Patologia Animal, um macaco-prego (Cebus apella para necropsia, que vinha apresentando emagrecimento profundo e lesões ulcerativas de pele e mucosas. Fragmentos de pele e órgãos foram processados para histologia e corados com H.E. e Groccot. Para micologia, coletaram-se fragmentos de órgãos, exsudato e crostas da pele, sendo realizado exame direto e cultivo a 37oC. Macroscopicamente, o animal apresentava alopecia, caquexia e ulcerações cutâneas de 1-4 cm. Histologicamente, nas ulcerações, a derme continha infiltrado de mononucleares e proliferação fibroblástica. Mediante utilização de Groccot, encontraram-se hifas e/ou pseudo-hifas e blastoconídeos intralesionais. Em cultivos de crostas e exsudato, observaram-se colônias brilhantes, com superfície lisa e coloração branca a creme. A microscopia das colônias revelou células leveduriformes ovaladas ou alongadas, com brotamento unipolar, gram-positivas. No microcultivo em fubá, observaram-se blastoconídeos globosos terminais, com parede espessa e pseudomicélio abundante e ramificado, com formação de tubo germinativo em albumina de ovo, sendo a levedura classificada como Candida albicans. O estudo aborda o risco da infecção por micoses oportunistas como a candidíase em animais silvestres em cativeiro.

    2014-01-01

    The title of this article is also its punch line. The thesis that I will prove is that every adult, with a few exceptions, should take one 325 mg aspirin tablet each day. The drug is extraordinary and is beneficial in myriad ways. In this dosage the toxicity of the treatment is minimal. Since the drug is sold "over the counter", not requiring prescription, it is cheap and its benefits are easily underestimated. I do not use extensive reference citations; but just tell the story of aspirin.

    CERN celebrated the fourth anniversary of the historical Higgs boson announcement with special pizzas.    400 pizzas were served on Higgs pizza day in Restaurant 1 at CERN to celebrate the fourth anniversary of the announcement of the discovery of the Higgs Boson (Image: Maximilien Brice/ CERN) What do the Higgs boson and a pizza have in common? Pierluigi Paolucci, INFN and CMS collaboration member, together with INFN president Fernando Ferroni found out the answer one day in Naples: the pizza in front of them looked exactly like a Higgs boson event display. A special recipe was then created in collaboration with the chef of the historic “Ettore” pizzeria in the St. Lucia area of Naples, and two pizzas were designed to resemble two Higgs boson decay channel event displays.

    1976-03-01

    Full Text Available Nas septicemias por Candida, a localização encefálica é rara, e apenas quatro casos isolados foram publicados no Brasil. Os AA. apresentam cinco observações anátomo-clínicas de candidíase do sistema nervoso central, diagnosticadas somente pela autópsia. Quatro dos pacientes eram adultos e apenas uma criança foi estudada. Todos eram portadores de uma ou mais doenças de base e foram submetidos à terapêutica antibiótica múltipla e prolongada. Os sintomas neurológicos eventualmente atribuíveis à infecção fúngica limitaram-se a convulsões em um caso e rigidez de nuca em outro. Em nenhum as lesões assumiram gravidade suficiente para serem responsabilizadas como causa imediata da morte. Revelaram-se múltiplas e microscópicas em três pacientes, com caráter exsudativo e granulomatoso; macroscópicas em um caso, com aspecto necro-hemorrágico. Na criança, dois granulomas apenas foram observados. O agente etiológico foi identificado como Candida, nos cortes histológicos, pela técnica de impregnação argêntica de Grocott. Os autores discutem a patogênese e a anatomia patológica da candidíase sistêmica, bem como seu diagnóstico clínico-laboratorial e a terapêutica. Os achados clínicos e an átomo-patológicos dos presentes casos são analisados à luz da literatura, enfatizando que a incidência de monilíase sistêmica no Brasil deve ser muito superior ao sugerido pela escassa casuística nacional.

  8. WE-G-204-04: Focal Spot Deblurring For High Resolution Amorphous Selenium (aSe) Complementary Metal Oxide Semiconductor (CMOS) X-Ray Detector

    Purpose: CMOS-based aSe detectors compared to CsI-TFT-based flat panels have the advantages of higher spatial sampling due to smaller pixel size and decreased blurring characteristic of direct rather than indirect detection. For systems with such detectors, the limiting factor degrading image resolution then becomes the focal-spot geometric unsharpness. This effect can seriously limit the use of such detectors in areas such as cone beam computed tomography, clinical fluoroscopy and angiography. In this work a technique to remove the effect of focal-spot blur is presented for a simulated aSe detector. Method: To simulate images from an aSe detector affected with focal-spot blur, first a set of high-resolution images of a stent (FRED from Microvention, Inc.) were acquired using a 75µm pixel size Dexela-Perkin-Elmer detector and averaged to reduce quantum noise. Then the averaged image was blurred with a known Gaussian blur at two different magnifications to simulate an idealized focal spot. The blurred images were then deconvolved with a set of different Gaussian blurs to remove the effect of focal-spot blurring using a threshold-based, inverse-filtering method. Results: The blur was removed by deconvolving the images using a set of Gaussian functions for both magnifications. Selecting the correct function resulted in an image close to the original; however, selection of too wide a function would cause severe artifacts. Conclusion: Experimentally, focal-spot blur at different magnifications can be measured using a pin hole with a high resolution detector. This spread function can be used to deblur the input images that are acquired at corresponding magnifications to correct for the focal spot blur. For CBCT applications, the magnification of specific objects can be obtained using initial reconstructions then corrected for focal-spot blurring to improve resolution. Similarly, if object magnification can be determined such correction may be applied in fluoroscopy and

RESULTADOS: São descritos quatro casos de ascaridíase biliar complicada em crianças (três pré escolares e um escolar, expressos através de pseudocisto pancreático, icterícia obstrutiva, colangite e múltiplos abscessos hepáticos, todos tratados cirurgicamente. Descrevemos detalhes técnicos da abordagem operatória para cada um dos casos. CONCLUSÕES: O espectro das afecções biliares secundárias à ascaridíase é variável e é necessário um arsenal de táticas operatórias para a abordagem de cada caso. É desaconselhável o uso de anti-helmínticos antes da resolução clínica da invasão da via biliar. A afecção preferencial de crianças jovens exige o uso de técnicas e materiais adequadamente delicados para a manipulação das vias biliares.BACKGROUND: To discuss the clinical expression and technical variations involved in the surgical treatment of complicated biliary ascariasis. METHODS: Retrospective study of patients operated on to treat complicated biliopancreatic ascariasis in a five year period. RESULTS: We describe four cases of complicated biliary ascariasis affecting children (three pre-schoolers and one school-aged child, clinically expressed as pancreatic pseudocyst, obstructive icterus, cholangitis and multiple hepatic abscesses, all surgically treated. We discuss aspects of operative treatment for each one of these patients. CONCLUSION: There are many variations concerning clinical and surgical presentations of biliary ascariasis, and a number of surgical tactics are necessary to solve those cases. We are against the use of anti-helmintics before the clearance of biliary passages. Preferential compromise of young children makes it necessary to use adequate and miniaturized

    2012-01-01

    The analytical method for 16 USEPA priority polycyclic aromatic hydrocarbons(PAHs) in soil was optimized in this study, and an integrated quality control (QC) system was established to resolve the problems occurring in PAHs analysis, such as the lower recoveries of benzo ( a) pyrene ( BaP) , unsatisfactory clean-up efficiency for samples in complex matrix, volatilization loss and environmental background of naphthalene ( Nap ) and phenanthrene ( Phe ). The analysis procedure commenced with accelerated solvent extraction ( ASE ) , followed by solid phase extraction ( SPE) clean-up and gradual condensation in vacuum. Gas chromatography - mass spectrometry ( GC - MS) was used for measurement. Deuterated benzo (a) pyrene (BaP - dl2) was used as an indicator of recovery in analysis. Three normal phase SPE materials were attempted to separate PAHs in samples, the results indicated that BaP was degraded when passing through florisil. Isotope dilution quantification was recommended to reduce the uncertainty of BaP analysis. Alumina was unsuitable for clean-up as for its strong adsorption to PAHs, but silica gel was proved to be the appropriate SPE material among the three candidates. The detection limits for the instrument and the analytical method were in the ranges of 0. 26 -5. 7 pg and 0. 067 -0. 97 ng/g(dry weight) , respectively.

  18. Seven remarkable days

    CERN Multimedia

    This has been a truly remarkable seven days for CERN. Things have moved so fast that it has sometimes been hard to separate fact from fiction – all the more so since facts have often seemed too good to be true. It’s been a week of many firsts. Monday was the first time we’ve had two captured beams in the LHC. It’s the first time the LHC has functioned as a particle accelerator, boosting particles to the highest beam energy so far achieved at CERN. And it’s been a week in which we’ve seen the highest energy proton-proton collisions ever produced at CERN: our last hadron collider, the SPS was a proton-antiproton collider, a technically simpler machine than the LHC. This week’s successes are all the more remarkable precisely because of the complexity of the LHC. Unlike the SPS collider, it is two accelerators not one, making the job of commissioning nearly twice as difficult. I’d like to express my heartfelt thanks and congra...

    With new machines, new services and new opening hours, the CERN Printshop has turned over many new leaves at the start of 2013. Come and find out more from 25 to 27 March at the Printshop open days!   The CERN Printshop’s new 8-metre long black and white printer. The CERN Printshop’s new 8-metre long black-and-white printer is a technical marvel. It can produce 160 pages per minute (it prints on both sides in one pass) and can also staple, punch holes, do thermal binding and make A4 or A5 brochures. The new colour printer is more discreet but no less efficient: it churns out 70 A4 or A3 pages per minute. Once they are printed, colour documents can be inserted into the black and white machine to be hole-punched, made into brochures or bound. They can even be mixed in with black-and-white pages and, as if by magic, come out in the right order! Having recently acquired a state-of-the-art large-format printer, the CERN Printshop can now print posters in A2, A1 or A0 format. ...

Warner Prize: Origins of Structure in Planetary Systems (by Erika Nesvold)Another excellent prize lecture started off todays sessions. The Helen B. Warner Prize is awarded for achievement in observational or theoretical astrophysics by a young researcher (no more than eight years after their Ph.D.). This years Warner Prize was presented to Ruth Murray-Clay of UC Santa Barbara. For her award lecture, Murray-Clay told us all about planetary system architecture: the number, masses, and orbits of planets in a given system.Ruth Murray-Clay [photo from http://web.physics.ucsb.edu/ ~murray/biocv.html]The underlying question motivating this type of research is: How rare is the Solar System? In other words, how likely is it that a given planetary system will have rocky planets close to their star, gas giants farther out, and ice giants at the outer reaches of the system? Answering this question will help us solve the physics problem of how and where planets form, and will also help us on our search for other planets like Earth.The data on exoplanet population from transit and radial velocity observations and from direct imaging tell us that our Solar System is not common (many systems we observe have much more eccentric gas giants), but that doesnt

    2011-01-01

    A new method using ASE combined with solid-phase extraction and GPC cleanup followed by HPLCtandem UV and fluorescence detection has been established for the quantitative determination of 16 PAHs in soils. In the method, the samples were extracted by ASE with acetone: dichloromethane (V:V, 50:50 )at 120 ℃, and dissolved in 9 mL hexane: ethyl acetate ( V: V, 50:50 ) after taking the extract to dryness with evaporation at 25 ℃. Then the extract was injected into GPC column with hexane:ethyl acetate( V: V,50:50)as the mobile phase at a flow rate of 5 mL·min-1 and GPC vacuum was 130 mbr/140 mbr. The 1340-3380 s fraction was collected for subsequent analysis. The portions collected from GPC were dissolved in 2 mL dichloromethane after taking the extract to dryness with nitrogen gas. Then the 2 mL extractions were purified by SPE using Florisil cartridges, eluted with 5 mL dichloromethane. Finally, the extraction was collected from SPE and dissolved in acetonitrile after taking it to dryness with nitrogen gas. The correlation coefficient of each PAH was r2 >0.99, the recovery fell within 62.9%-118.9%, and the relative standard derivation of PAHs was between 0.6% and 19.9%.

    Full Text Available Por meio da etofamida, trataram os autores 40 indivíduos acometidos de amebíase intestinal e representados por crianças e adultos de ambos os sexos. Os esquemas posológicos recomendados para os componentes de dois grupos de 20 elementos foram os seguintes: A 100 mg três vezes em 24 horas, durante cinco dias; B 100 mg, cinco vezes em 24 horas, durante três dias. Foi expressiva a percentagem global de 90% de curas obtidas, mas a administração de maior quantidade diária da droga, durante período mais curto, mostrou-se dotada de melhor efetividade e possibilitou a eliminação da parasitose de todas as pessoas medicadas. O estudo que efetuaram, correspondente à amebíase intestinal assintomática, oligossintomática ou aparente como colite crônica, deixou patente a eficácia do remédio usado, que praticamente não causou distúrbios colaterais e pode ser prescrito segundo planejamentos singelos e executáveis com facilidade.

    Full Text Available A ciclosporina tem sido contraindicada nos pacientes com infecções crônicas, como a infecção pelo vírus da hepatite C, devido ao seu efeito imunossupressor. No entanto, estudos recentes têm demonstrado que a ciclosporina suprime a replicação viral e pode, desta forma, não exacerbar a infecção pelo vírus da hepatite C, quando administrada como tratamento para pacientes com psoríase. Apresentamos o caso de uma paciente portadora de psoríase há 30 anos e hepatite C há 20 anos, com lesões circinadas difusas, que apresentou melhora cutânea e das enzimas hepáticas com o uso da ciclosporina, sem apresentar nenhum efeito adversoCyclosporine has been contraindicated in patients with chronic infections such as infection with hepatitis C because of its immunosuppressive effect. Recent studies have shown however that cyclosporine suppresses viral replication and thus cannot exacerbate infection with hepatitis C when employed for treating patients with psoriasis. We present the case of a female patient with psoriasis for 30 years and hepatitis C for 20 years, with diffuse circinate lesions. Improvement in the skin condition and liver enzymes was obtained with the use of cyclosporine, with no adverse effect

  12. Asp-ase Activity of the Opossum Granzyme B Supports the Role of Granzyme B as Part of Anti-Viral Immunity Already during Early Mammalian Evolution.

    Directory of Open Access Journals (Sweden)

    Zhirong Fu

    Full Text Available Granzyme B is one of the key effector molecules in our defense against viruses and intracellular bacteria. This serine protease together with the pore forming protein perforin, induces caspase or Bid-dependent apoptosis in target cells. Here we present the first characterization of a granzyme B homolog, the grathepsodenase, in a non-placental mammal, the American opossum (Monodelphis domestica. The recombinant enzyme was produced in a human cell line and used to study its primary and extended cleavage specificity using a panel of chromogenic substrates and recombinant protein substrates. The opossum granzyme B was found to have a specificity similar to human granzyme B, although slightly less restrictive in its extended specificity. The identification of a granzyme B homolog with asp-ase (cleaving after aspartic acid specificity in a non-placental mammal provides strong indications that caspase or Bid-dependent apoptosis by a serine protease with a conserved primary specificity has been part of anti-viral immunity since early mammalian evolution. This finding also indicates that an asp-ase together with a chymase were the first two serine protease genes to appear in the mammalian chymase locus.

Ozel spoke to a packed room (at 8:30am!) about where the project currently stands, and where its heading in the future.The EHT has pretty much the coolest goal ever: actually image the event horizons of black holes in our universe. The problem is that the largest black hole we can look at (Sgr A*, in the center of our galaxy) has an event horizon size of 50 as. For this kind of resolution roughly equivalent to trying to image a DVD on the Moon! wed need an Earth-sized telescope. EHT has solved this problem by linking telescopes around the world, creating one giant, mm-wavelength effective telescope with a baseline the size of Earth.Besides producing awesome images, the EHT will be able to test properties of black-hole spacetime, the no-hair theorem, and general relativity (GR) in new regimes.Ozel walked us through some of the theory prep work we need to do now in order to get the most science out of the EHT, including devising new

Two of the hot topics at this years meeting include celebration of the recent move of the National Solar Observatorys headquarters to Boulder, and discussion of the future Daniel K. Inouye Solar Telescope (DKIST, formerly the Advanced Technology Solar Telescope, ATST). DKIST, planned for a 2019 completion in Hawaii, is the next big telescope on the horizon for solar physics.Todays press conference had an interesting focus: instruments providing new high-energy observations of the Sun. Representatives from four different instruments were here to talk about some of the latest X-ray solar observations.GRIPSThe GRIPS payload flew at 130,000 ft over Antarctica on a giant balloon in January 2016. [NASA/Albert Shih]First up, Albert Shih (NASA Goddard) described the Gamma-Ray Imager/Polarimeter for Solar flares, or GRIPS. GRIPS is a balloon-borne instrument designed to detect X-rays and gamma rays emitted during solar flares. Up to tens of a percent of the energy in solar flares is emitted in the form of accelerated particles, but the physics behind this process is not well understood. GRIPS observes where the highest-energy particles are accelerated, in an effort to learn more about the process.GRIPS was launched on 19 January, 2016 and flew for roughly 12 days gathering ~1 million seconds of data! The logistics of this instruments flight are especially interesting, since it was launched from Antarctica and carried by a balloon at a whopping elevation of 130,000 ft (to get high enough that the atmosphere doesnt absorb all the photons GRIPS is trying to observe). Though the data from the mission has been retrieved, the bulk of the hardware remains where it landed at the end of January. It must

    advances in simulating sunspot formation. He and his collaborators have used high-performance computing to build a model that successfully reproduces many of the key properties of sunspots that are observed.In particular, these simulations track the motions of the magnetic field starting within the interior of the Sun (8000 km below the surface!). The magnetic field is generated and intensified by convection deep within the solar interior. Bundles of magnetic field then rise through the convection zone, eventually breaking through the solar surface and giving rise to sunspots.This process of tracking the flow as it travels from the convective layer all the way through the solar surface has resulted in what may be some of the highest fidelity simulations of sunspots thus far. The structures produced in these simulations compares very favorably with actual observations of sunspots including the asymmetry seen in most sunspots.Counting Spots on the SunContinuing the discussion of sunspots, Leif Svalgaard (Stanford University) next took us on a historical journey from the 1600s through the present. For the last 400 years starting with Galileo people have kept records of the number of sunspots visible on the Suns disk.One of Galileos drawings of his sunspot observations from 1612. [The Galileo Project]This turns out to be a very useful practice! Total solar irradiance, a measure used as input into climate models, is reconstructed from sunspot numbers. Therefore, the historical record of sunspots over the last 400 years impacts our estimates of the long-term trends in solar activity.Based on raw sunspot counts, studies have argued that solar activity has been steadily increasing over time. But could this be a misinterpretation resulting from the fact that our technology and therefore our ability to detect sunspots has improved over time? Svalgaard believes so.By studying and reconstructing 18th century telescopes, he demonstrates that modern-day sunspot counts are able to detect

WKU is located a little over an hour away, and both locations are prepared for a large influx of people on eclipse day!Partial solar eclipse as viewed by the space-based Solar Dynamics Observatory. [NASA/SDO]WKU is located just off the centerline of eclipse path, which has some advantages: this provides better viewing of some of the chromospheric features of the Sun during the eclipse, like priminences and solar loops. WKU is setting up a variety of educational and public outreach activities at their football stadium and the WKU farm, and they encourage you to come visit for the eclipse!In addition, they are participating in a nationwide experiment called Citizen CATE, short for the Continental American Telescopic Eclipse. This project will use 60 telescopes spanning the 2500 mile path of totality to record continuous data of the eclipse as it travels across the US. The result will be data of a remarkable 90 minutes of totality, revealing the activity of the solar corona and providing an extended view of the eclipse as has never been seen before.Science During the EclipseNext up was Shadia Habbal (University of Hawaii), who is a co-leader of the AAS 2017 Eclipse Task Force.

He describes the NRES, a network of spectrographs that will look for exoplanets using the radial velocity method. One of the coolest aspects of this instrument is that it will feature an on the fly scheduling system that will perform observations as efficiently as possible. The spectrograph is still being tested, but a unit will be deployed at CTIO later this year.@lcogt contracted by @NASA_TESS for follow up of their candidates. #aas228 Jessie Christiansen (@aussiastronomer) June 16, 2016Measuring the depths of transits and eclipses in Spitzer has been problematic in the past, since the Spitzer instrument IRAC (InfraRed Array Camera) has a non-uniform response in its detectors pixels. But, as reported by James Ingalls (Spitzer Science Center, Caltech), observers are circumventing this issue by using what they call the staring mode (avoiding large pointing jumps) and an algorithm to pick sweet spot pixels. Moreover, the results from the IRAC Data Challenge are helping to better understand its behavior. Giuseppe Morello (University College London), on the other hand, explained how his research group gets rid of instrumental effects from IRAC using machine learning. This method removes systematics from exoplanet transit data no matter if the noise source is from an instrument or

A pentoxifilina (PTX é uma metilxantina que inibe vários mecanismos inflamatórios. OBJETIVO: Estudar os efeitos da PTX sobre os dendróticos dérmicos de placas de psoríase com técnicas imuno-histoquímicas. MATERIAL E MÉTODOS: Trinta biópsias de placas de psoríase antes e após oito semanas de uso oral diário de 1.200mg de PTX foram incubadas com anticorpo primário de coelho antiFator XIIIa e anticorpo de ligação conjugado com fosfatase alcalina. RESULTADOS: As células imunomarcadas Fator XIIIa+ foram proeminentes com morfologia dendrítica arborescente na derme papilar formando linha celular logo abaixo da epiderme e exibindo arranjo nodular ao redor dos vasos. Após tratamento, as células apresentaram-se com morfologia dendrítica e fusiforme, distribuídas ao redor dos vasos da derme papilar e predominantemente fusiformes dispostas paralelamente à junção dermoepidérmica retificada. CONCLUSÕES: A PTX promove aumento do fluxo sangüíneo e diminuição da adesividade endotelial, com aumento dos mastócitos e DD FXIIIa. A PTX inibe o TNF-alfa, que implica a diminuição da expressão de receptores pelos DDs, como CCR7 e a manutenção do estímulo tecidual para sinalização e migração dos precursores, uma vez que os processos etiopatogenéticos não são afetados pela droga.BACKGROUND: There is no consensus about dermal dendrocytes (DD function on physiopathological events on psoriasis.

    The outdoors intensive-type pig production is characterized by maintaining swine during reproductive, pregnancy and nursing periods on pasture limited by wiring and/or electric fences. The aim of the present report was to describe the epidemiological aspects of an outbreak of Tunga penetrans in an outdoor pig production system. A total of six mature boars, 9 lactating sows, 13 pregnant sows, 9 mating sows, 20 suckling pigs and 34 weaned pigs were clinically examined. None of the boars were infested, while 50% of all sows examined had the parasite lesions, most frequently observed in the breast area, thus resulting in agalactia in lactating sows due to obstruction of the galactophorus channel, with subsequent involution of the mammary gland. In 90% of suckling piglets walking difficulty was observed, caused by the presence of the parasite in the hoofs, with 25% of these animals also showing hock lesions (farm number 1, n = 48. Similar lesions were observed in 100% of 40-47 days old weaned pigs (farm number 2, n = 24 and in 80% of 70 days old weaned pigs (farm number 3, n = 10, all of which had been transferred to finishing units in a confinement system. Therefore we conclude that Tunga penetrans can infest pigs reared or kept outdoors, causing agalactia in lactating sows, and walking disorders in suckling and weaned pigs.

MÉTODOS: O estudo foi realizado em Recife, PE, de acordo com 94 bairros analisados. A fonte de coleta de dados foi o Sistema de Informações sobre Agravos de Notificação do Ministério da Saúde. Foi adotada uma abordagem ecológica com utilização do método bayesiano empírico para suavização local de taxas, a partir de informações de bairros vizinhos por adjacência. RESULTADOS: A ocorrência média anual foi de 17,3% de casos novos em menores de 15 anos (28,3% de formas multibacilares, indicando um processo de intensa transmissão da doença. A análise da distribuição espacial de hanseníase apontou três áreas onde se concentram bairros com taxas de detecção elevadas e que possuem baixa condição de vida. CONCLUSÕES: O emprego do modelo bayesiano, baseado em informações de unidades espaciais vizinhas, permitiu estimar novamente indicadores epidemiológicos. Foi possível identificar áreas prioritárias para o programa de controle de hanseníase no município, tanto pelo elevado número de ocorrências correlacionado �� presença de formas multibacilares de doença em menores de 15 anos quanto pela existência de subnotificação.

    Content analysis-ICF linking. The Patient Rated Elbow Evaluation (PREE) and the self-report section of the American Shoulder and Elbow Surgeons society - Elbow form (ASES-e) are the two commonly used elbow pain and disability self-report measures (PROs). The content of these questions have never been analyzed in light of the International Classification of Functioning Disability and Health (ICF) which is the current standard to describe health and health-related states. The purposes of this study were to analyze the conceptual basis of the PREE and the ASES-e by linking the meaningful concepts in these PROs to the ICF using standardized linking rules and to determine the extent to which the ICF core set for hand conditions cover the content of elbow questionnaires using summary ICF linkage indicators. Two raters linked the two PROs to the ICF using the linking rules proposed by Cieza and colleagues. Percentage agreement was calculated between the raters. Summary linkage indicators proposed by MacDermid were used to estimate the extent to which the ICF core set for hand conditions cover the content of the elbow questionnaires. All the items of the PREE (Measure to ICF linkage - 100%) and all but one item of the pASES-e (Measure to ICF linkage - 95%) were linked to the ICF. The satisfaction item on the ASES-e was not-covered by the ICF. Percentage agreement on linking between the raters was 96% and 95% for the PREE and the pASES-e respectively. The unique linkage of the PREE and the pASES-e to the unique codes on the brief and comprehensive core set were lower than absolute linkage to the core set for hand conditions. The PROs represented less than 20% of the comprehensive core set and more than 70% of the brief core set. While for the unique core set disability representation the 2 PROMs represented 100% brief core set unique disability codes and less than 35% of the comprehensive core set unique disability codes.

    For sustainable growth of the Internet, wavelength-tunable optical regeneration is the key to scaling up high energy-efficiency dynamic optical path networks while keeping the flexibility of the network. Wavelength-tunable optical parametric regenerator (T-OPR) based on the gain saturation effect of parametric amplification in a highly nonlinear fiber is promising for noise reduction in phase-shift keying signals. In this paper, we experimentally evaluated the T-OPR performance for ASE-degraded 43-Gb/s RZ-DPSK signals over a 20-nm input wavelength range between 1527 nm and 1547 nm. As a result, we achieved improved power penalty performance for the regenerated idler with a proper pump power range.

    In this paper, an improved multi-carrier generation scheme based on single-side-band recirculating frequency shifter with optical finite impulse response (FIR) filter for amplified spontaneous emission (ASE) noise suppression is proposed and experimentally demonstrated. The carrier-to-noise-ratio (CNR) instead of tone-to-noise-ratio (TNR) is introduced to more reasonably and exactly evaluate the signal-to-noise-ratio of a multi-carrier source with non-flat noise floor. We have experimentally attain the worst case CNR of 22.5dB and 19.1dB for generated 50 and 69 flat low noise carriers, which has shown significant improvement than the previous cited works based on recirculating frequency shifter.

    Full Text Available O presente trabalho demonstra a eficácia do método imunoenzimático utilizando antígeno solúvel de larvas de Strongyloides stercoralis no diagnóstico da estrongiloidíase humana. Foram avaliados 27 pacientes com as diversas formas clínicas da parasitose, sendo demonstrados títulos significativos em 25 (92% dos casos. Em 17 controles, com ou sem outrasparasítoses intestinais, títulos significativos estavam presentes em 3 (18%. A sensibilidade do teste foi de 92% e a especificidade de 82%. São também relatados 3 casos clínicos, nos quais o diagnóstico da doença foi feito inicialmente pela determinação de anticorpos contra larvas de S. stercoralis, havendo posteriormente demonstração parasitológica em 2 dos casos. É ressaltada a importância do teste no diagnóstico da estrongiloidíase aguda e em situações onde eosinofilia não esteja associada a outras condições clínicas.The detection of antibodies to S. stercoralis antigen by using the Enzyme Linked Immunosorbent Assay was evaluated in 27 patients with strongyloidiasis diagnosed by demonstration of larvae of S. stercoralis in the stool. Significant titers of antibody were observed in 25 (92% patients. In 17 controls with or without other parasitic infections, titers were considered positive in 3 (18%. We also report three cases in which the diagnosis of strongyloidiais was initially made only by the serological test These observations suggest that documentation of antibody to S. stercoralis by the ELISA technique may contribute to the diagnosis of strongyloidiasis. In addition, the test may be of great value in acute strongyloidiasis and in the diagnosis of patients with unexplained eosinophilia.

    Full Text Available OBJETIVO: Considerando a alta freqüência da colelitíase no paciente pediátrico com doença falciforme e a controvérsia na literatura sobre a abordagem da condição, o presente texto objetiva revisar a literatura disponível. FONTE DE DADOS: Revisão dos estudos sobre colelitíase no paciente falciforme, publicados no período entre 1980 e 2007, em língua inglesa e portuguesa, envolvendo pacientes na faixa etária de zero a 18 anos e utilizando os bancos de dados Medline e Lilacs. SÍNTESE DOS DADOS: A colelitíase é a complicação digestiva mais comum no paciente falciforme e sua incidência aumenta com a faixa etária. Os mecanismos fisiopatológicos são conhecidos, assim como os métodos diagnósticos. A conduta terapêutica consensual na colelitíase sintomática é a colecistectomia, preferencialmente por via laparoscópica. Nos casos assintomáticos, a maioria dos autores recomenda a conduta cirúrgica, para evitar complicações, confusão no diagnóstico diferencial de dor abdominal futura e menor risco cirúrgico. Contudo, não existe consenso na literatura, havendo base para a adoção de conduta expectante. CONCLUSÕES: A doença falciforme tem grandes variações em sua apresentação clinica, história natural e gravidade da hemólise. Algumas populações podem apresentar menor freqüência de colelitíase e menor número de pacientes sintomáticos, possivelmente em razão de variações de haplótipos, fatores ambientais e diferentes manejos clínicos. Ainda não existem dados suficientes na literatura ou estudos randomizados e controlados que possibilitem definir o momento ideal para a colecistectomia no paciente falciforme com litíase assintomática. Dessa maneira, dependendo de características individuais e da população, podem ser aceitos o seguimento clínico ou a indicação precoce de colecistectomia.OBJECTIVE: Given the high frequency of cholelithiasis in children with sickle cell disease and the controversies

    Full Text Available O encontro de parasitos em material arqueológico tem permitido o acompanhamento da dispersão de agentes infecciosos e seus hospedeiros humanos no passado. Através desses achados, pôde-se retomar teorias propostas no início do século sobre contatos transpacíficos de populações asiáticas com a América do Sul. Assim foi feito, por exemplo, no caso do encontro de ovos de ancilostomídeos em material arqueológico datado de até sete mil anos antes do presente. O aumento da produção científica na área torna necessária, agora, a realização de trabalhos de síntese que avaliem o estado da arte e proponham modelos paleoepidemiológicos compreensíveis para a dispersão pré-histórica das parasitoses humanas. Nesse sentido, foi feito o presente trabalho, a partir dos recentes achados de ovos de Enterobius vermicularis em material arqueológico nas Américas. Diferentemente da infecção por ancilostomídeos, a oxiuríase não necessita de passagem pelo solo para a transmissão de um hospedeiro a outro, logo, sua persistência em uma dada população humana independe das condições climáticas. Poderia, portanto, ter sido trazida do velho para o novo continente, inclusive pelas migrações humanas que atravessaram o estreito de Bering. Tal fato pode explicar a maior dispersão geográfica dos achados e sua disseminação na América do Norte, desde dez mil anos até os tempos atuais. Na América do Sul, por outro lado, os achados arqueológicos só confirmaram sua existência ao longo da região andina, com achados no Chile e no Norte da Argentina. No Brasil, apesar do grande número de amostras examinadas, não foram encontrados ovos de Enterobius vermicularis em coprólitos. No presente trabalho, discutem-se modelos explicativos para a distribuição conhecida dessa parasitose em populações pré-históricas.Parasite findings in archeological material have made it possible to trace the dispersion of infectious agents and their human

    2015-06-15

    Purpose: To evaluate the task specific imaging performance of a new 25µm pixel pitch, 1000µm thick amorphous selenium direct detection system with CMOS readout for typical angiographic exposure parameters using the relative object detectability (ROD) metric. Methods: The ROD metric uses a simulated object function weighted at each spatial frequency by the detectors’ detective quantum efficiency (DQE), which is an intrinsic performance metric. For this study, the simulated objects were aluminum spheres of varying diameter (0.05–0.6mm). The weighted object function is then integrated over the full range of detectable frequencies inherent to each detector, and a ratio is taken of the resulting value for two detectors. The DQE for the 25µm detector was obtained from a simulation of a proposed a-Se detector using an exposure of 200µR for a 50keV x-ray beam. This a-Se detector was compared to two microangiographic fluoroscope (MAF) detectors [the MAF-CCD with pixel size of 35µm and Nyquist frequency of 14.2 cycles/mm and the MAF-CMOS with pixel size of 75µm and Nyquist frequency of 6.6 cycles/mm] and a standard flat-panel detector (FPD with pixel size of 194µm and Nyquist frequency of 2.5cycles/mm). Results: ROD calculations indicated vastly superior performance by the a-Se detector in imaging small aluminum spheres. For the 50µm diameter sphere, the ROD values for the a-Se detector compared to the MAF-CCD, the MAF-CMOS, and the FPD were 7.3, 9.3 and 58, respectively. Detector performance in the low frequency regime was dictated by each detector’s DQE(0) value. Conclusion: The a-Se with CMOS readout is unique and appears to have distinctive advantages of incomparable high resolution, low noise, no readout lag, and expandable design. The a-Se direct detection system will be a powerful imaging tool in angiography, with potential break-through applications in diagnosis and treatment of neuro-vascular disease.

Duas etapas para coletas de informações foram realizadas. Na primeira, os hansenianos responderam a um questionário com perguntas estruturadas; na segunda, foram ouvidos relatos de situações vividas no cotidiano de dez homens e mulheres. Os dados revelaram que a doença mobilizou representações diferentes entre os homens e mulheres nos diferentes grupos sociais. A hanseníase representou um desequilíbrio entre os gêneros, acentuando as desigualdades já existentes no campo sócio-cultural e criando novos problemas responsáveis pelos prejuízos bio-psico-sociais e econômicos, além dos estigmas que pesam sobre os indivíduos. Tais resultados devem reorientar os programas de controle e tratamento, visando à recuperação social dos hansenianos, e também servir de paradigma a novas investigações.On the basis of social representations, we detected gender differences in family and individual living experiences for people with Hansen's disease (HD, or leprosy in a sample of 202 HD patients (132 men and 70 women enrolled in a public treatment and control program in Ribeirão Preto, São Paulo State.

    Full Text Available Parasitological diagnosis based on the faecal examination is frequently difficult in cases of chronic, low-level S. stercoralis infection. Even when a newly developed sensitive method (an agar plate culture is applied, it is essential to examine faecal samples repeatedly to achieve a correct diagnosis. Additionally, it is important to note that a negative result does not necessarily indicate the unequivocal absence of the infection. On the other hand, several serological tests which have recently been developed for strongyloidiasis have proven reliable when used to complement parasitological examination. We have developed two serological tests, ELISA and GPAT, to demonstrate Strongyloides infection and possible applications of the serological tests for diagnosis, mass-screening, epidemiological study and postchemotherapy evaluation of strongyloidiasis were reviewed based on our recent studies.O diagnóstico parasitológico baseado no exame de fezes é muitas vezes difícil, principalmente nos casos de infecções crônicas ou leves pelo S. stercoralis. Mesmo utilizando o mais novo e sensível método (cultura em placas de ágar é essencial examinar repetidamente as amostras fecais, para um diagnóstico correto. É importante ressaltar também que o resultado negativo não indica de modo inequívoco a ausência da infecção. Por outro lado, vários testes sorológicos recentemente desenvolvidos para estrongiloidíase tem provado a sua eficácia quando usados para complementar exames parasitológicos. Para demonstrar infecção por Strongyloides desenvolvemos dois tipos de testes sorológicos - ELISA e GPAT - e, com base em nossos recentes estudos, apresentamos uma opinião sobre sua possível aplicação para screening em massa, estudos epidemiológicos e avaliação pós-tratamento de estrongiloidíases.

O diagnóstico da infestação por Otodectes cynotis foi realizado através de otoscopia bilateral e pela coleta de material e visualização do parasito sob microscópio esterioscópico, constituindo o exame parasitológico. Outras coletas de secreção otológica de cada orelha foram realizadas para confecção de lâminas para a citologia e para o isolamento microbiológico, sendo este último material coletado através de "swab" estéril. Dos 250 animais examinados, em 15 (6% foi identificado o ácaro O. cynotis.Observou-se associação entre a presença do parasito e a ocorrência de otite clínica externa caracterizada especialmente por eritema auricular (P<0,001 e a produção excessiva de secreção otológica (P=0,0016, assim como a observação, pelos proprietários, de prurido ótico nos cães (P<0,001.

    Full Text Available Abstract Background The risk of sporadic colorectal cancer is mainly associated with lifestyle factors and may be modulated by several genetic factors of low penetrance. Genetic variants represented by single nucleotide polymorphisms in genes encoding key players in the adenoma carcinoma sequence may contribute to variation in susceptibility to colorectal cancer. In this study, we aimed to evaluate whether the recently identified haplotype encompassing genes of DNA repair and apoptosis, is associated with increased risk of colorectal adenomas and carcinomas. Methods We used a case-control study design (156 carcinomas, 981 adenomas and 399 controls to test the association between polymorphisms in the chromosomal region 19q13.2-3, encompassing the genes ERCC1, ASE-1 and RAI, and risk of colorectal adenomas and carcinomas in a Norwegian cohort. Odds ratio (OR and 95% confidence interval (CI were estimated by binary logistic regression model adjusting for age and gender. Results The ASE-1 polymorphism was associated with an increased risk of adenomas, OR of 1.39 (95% CI 1.06–1.81, which upon stratification was apparent among women only, OR of 1.66 (95% CI 1.15–2.39. The RAI polymorphism showed a trend towards risk reduction for both adenomas (OR of 0.70, 95% CI 0.49–1.01 and carcinomas (OR of 0.49, 95% CI 0.21–1.13 among women, although not significant. Women who were homozygous carriers of the high risk haplotype had an increased risk of colorectal cancer, OR of 2.19 (95% CI 0.95–5.04 compared to all non-carriers although the estimate was not statistically significant. Conclusion We found no evidence that the studied polymorphisms were associated with risk of adenomas or colorectal cancer among men, but we found weak indications that the chromosomal region may influence risk of colorectal cancer and adenoma development in women.

    Full Text Available Hepatobiliary alterations found in an autopsy case of massive Biliary Ascariasis, are reported on histological grounds. Severe cholangitis was the main finding, but other changes were also detected, such as pyloric and intestinal metaplasia, hyperplasia of the epithelial lining, with intraductal papillomas and adenomatous proliferation. Remnants of the worm were observed tightly adhered to the epithelium, forming microscopic intrahepatic calculi. Mucopolysaccharides, especially acid, showed to be strongly positive on the luminal border, and in proliferated glands around the ducts. The authors discuss the similarity between such findings and Oriental Cholangiohepatitis, and suggest that inflammation and the presence of the parasitic remnants are responsible for the hyperplastic and metaplastic changes, similarly with what occurs in chlonorchiasis, fascioliasis and schistosomiasis.Os autores apresentam os aspectos histopatológicos encontrados no fígado de um caso de autópsia de Ascaridíase Biliar maciça. A intensa colangite foi o aspecto predominante, mas outras lesões também foram encontradas, tais como metaplasia pilórica e intestinal, hiperplasia epitelial com papilomas intraductais, e por vezes padrão adenomatoso. Restos do helminto foram encontrados fortemente aderidos ao epitélio, sendo intensa a positividade de mucopolissacárides, principalmente ácidos, na borda luminal do epitélio ductal e em glândulas proliferadas ao redor dos ductos. Os autores discutem a semelhança da Ascaridíase Biliar com a Colangio Hepatite Oriental, e sugerem que o processo inflamatório e a presença de restos do verme são responsáveis pelas alterações hiperplásicas e metaplásicas, analogamente ao que ocorre na clonorquíase, fasciolíase e esquistossomose.

    For more than half a century, the 1959 Antarctic Treaty continues to shine as a rare beacon of international cooperation. To celebrate this milestone of peace in our civilization with hope and inspiration for future generations, Antarctica Day is celebrated each year on December 1st , the anniversary of the Antarctic Treaty signing. As an annual event - initiated by the Foundation for the Good Governance of International Spaces (www.internationalspaces.org/) in collaboration with the Association of Polar Early Carer Scientists (www.apecs.is) - Antarctica Day encourages participation from around the world. The Antarctic Treaty set aside 10% of the earth, 'forever to be used exclusively for peaceful purposes in the interest of mankind.' It was the first nuclear arms agreement and the first institution to govern all human activities in an international region beyond sovereign jurisdictions. In this spirit, Antarctica Day aims to: - Demonstrate how diverse nations can work together peacefully, using science as a global language of cooperation for decision making beyond national boundaries, - Provide strategies for students learning about Antarctica through art, science and history at all school levels, - Increase collaboration and communication between classrooms, communities, researchers and government officials around the world, and - Provide a focus for polar educators to build on each year. Through close collaboration with a number of partners. Antarctica Day activities have included: a Polar Film Festival convened by The Explorers Club; live sessions connecting classrooms with scientists in Antarctica thanks to PolarTREC and ARCUS; an international activity that involved children from 13 countries who created over 600 flags which exemplify Antarctica Day (these were actually flown in Antarctica with signed certificates then returned to the classes); a map where Antarctica Day participants all over the world could share what they were doing; an Antarctic bird count

    We present the fluorescence spectroscopy of a range of Dy3+ doped tellurite (TeO2) and germanate (GeO2) glasses and compare with Dy3+ doped ZBLAN glass. When excited using an 808 nm laser diode, Dy3+ ions emit radiation at around 3 μm from the 6H13/2→ 6H15/2 (3500 cm-1) energy level transition, which has been exploited in Dy3+ doped fluoride fibre lasers. When Dy3+ is doped into TeO2 and GeO2 based glasses, the fluorescence from the 6H13/2→ 6H15/2 transition is shown to be broader and red-shifted compared to that in ZBLAN glass. Mid-IR ASE from a fs laser inscribed Dy3+ doped tellurite glass waveguide is also presented. The results of Dy3+ mid-IR fluorescence spectroscopy and the potential of oxide glasses as mid-IR sources are discussed.

  1. On the Transfer and Control of Space Probes Around the L1 Point of the Sun-Earth+Moon System

    Hou, Xi-Yun; Liu, Lin

    2008-01-01

    The motion around the collinear libration points in the restricted three body problem is unstable. But there exist conditionally stable periodic orbits around these points. Special-purpose space probes located in the vicinity of these points (e.g., ISEE-3, SOHO) can benefit from this dynamical property, in regard to maintaining the orbit in position and the energy required of placing the probe in position. As an example, we study in this paper the launch and orbital control of a space probe around the L1 libration point in the system consisting of the Sun and the Earth-Moon. We present some theoretical and numerical simulations' results, which may serve as a basis for the realization of such a space probe in future.

    Srivastava, Vineet K.; Kumar, Jai; Kushvah, Badam Singh

    2016-12-01

    In this paper, we construct a third-order analytic approximate solution using the Lindstedt-Poincare method in the photogravitational circular restricted three body problem considering the Sun as a radiating source and the Earth as an oblate spheroid for computing halo orbits around the collinear Lagrangian points L1 and L2. Further, the well-known differential correction and continuation schemes are used to compute halo orbits and their families numerically. The effects of solar radiation pressure and oblateness on the orbit are studied around both Lagrangian points. From the study, it is noticed that time period of the halo orbit increases around L1 and L2 accounting oblateness of the Earth and solar radiation pressure of the Sun. It is also found that stability of halo orbits is a weak function of the out-of-plane amplitude and mass reduction factor.

    2005-05-01

    A large Coronal Mass Ejection (CME) can consist of billions of tonnes of matter, along with entangled magnetic field, erupting from the Sun at speeds well over 1,000 km/s. These giant disruptions of the solar atmosphere drive the most destructive space weather at Earth and throughout the solar system. Furthermore, CMEs are the most dramatic example of how slowly-evolving processes on the Sun can conspire to produce explosive activity. Understanding their origin has long been a central objective for space physics research. This talk will present some of the latest observations and theories for CMEs and discuss the outstanding challenges to modeling and predicting their initiation. This work was supported in part by NASA and ONR.

    DSCOVR Lissajous Orbit sized such that orbit track never extends beyond 15 degrees from Earth-Sun line (as seen from Earth). Requiring delta-V maneuvers, control orbit to obey a Solar Exclusion Zone (SEZ) cone of half-angle 4 degrees about the Earth-Sun line. Spacecraft should never be less than 4 degrees from solar center as seen from Earth. Following Lissajous Orbit Insertion (LOI), DSCOVR should be in an opening phase that just skirts the 4-degree SEZ. Maximizes time to the point where a closing Lissajous will require avoidance maneuvers to keep it out of the SEZ. Station keeping maneuvers should take no more than 15 minutes.

  6. Short term Variability of the Sun Earth System: An Overview of Progress Made during the CAWSES II Period

    CERN Document Server

    Gopalswamy, Nat; Yan, Yihua

    2015-01-01

    This paper presents an overview of results obtained during the CAWSES II period on the short term variability of the Sun and how it affects the near Earth space environment. CAWSES II was planned to examine the behavior of the solar terrestrial system as the solar activity climbed to its maximum phase in solar cycle 24. After a deep minimum following cycle 23, the Sun climbed to a very weak maximum in terms of the sunspot number in cycle 24 (MiniMax24), so many of the results presented here refer to this weak activity in comparison with cycle 23. The short term variability that has immediate consequence to Earth and geospace manifests as solar eruptions from closed field regions and high speed streams from coronal holes. Both electromagnetic (flares) and mass emissions (coronal mass ejections, CMEs) are involved in solar eruptions, while coronal holes result in high speed streams that collide with slow wind forming the so called corotating interaction regions (CIRs). Fast CMEs affect Earth via leading shocks ...

    Kappenman, J. G.

    2004-05-01

    The solar flare activity of October-November 2003 reached historic intensity levels and produced several large Earth-directed CME's that had the potential to cause historically large geomagnetic storms as well. These CME's did cause various geomagnetic storm indices, particularly the regional K and Planetary Kp index, to reach maximum levels for many hours. However, the resulting geomagnetic storms, while causing isolated and important disruptions to power grids, were not of historically large size when considering the rate-of-change of regional geomagnetic fields in many locations. Impacts to power grids are caused by large dB/dt variations in regional geomagnetic fields, in most cases the peak geomagnetic disturbance intensities (in nT/min) were only a fraction of what has occurred during historically large geomagnetic storm events. A review will be provided of the CME passages and features of the passage that drove resulting geomagnetic storm events and impacts to electric power grid infrastructures on October 29-30, 2003. A brief overview of the geomagnetic storm disturbance morphologies and intensities relative to other noteworthy storms will also be provided.

    Large solar particle events (SPE) threaten many elements of critical infrastructure. A 2013 study by Lloyds of London and Atmospheric and Environmental Research recently found that if a worst-case solar event like the 1859 Carrington Event struck our planet now, it could result on $0.6-$2.36 trillion in damages to the economy. In March 2014, researchers Y. D. Liu et al. revealed that just such an event had narrowly missed Earth in July 2012. The event was observed by the STEREO A spacecraft. In this presentation, we examine how the sun can pack such a punch from 150 million km away, the threats such solar particle events pose, their mechanisms and the efforts NASA and other space agencies are carrying out to understand and mitigate such risks.
