    To promote awareness of the Sun-Earth connection, NASA's Marshall Space Flight Center, in collaboration with the Stanford SOLAR Center, sponsored a one-day Sun-Earth Day event on April 27, 2001. Although "celebrated" on only one day, teachers and students from across the nation, prepared for over a month in advance. Workshops were held in March to train teachers. Students performed experiments, results of which were shared through video clips and an internet web cast. Our poster includes highlights from student experiments (grades 2 - 12), lessons learned from the teacher workshops and the event itself, and plans for Sun-Earth Day 2002.

    Sun-Earth Connection scientists have established partnerships with several minority professional societies to reach out to the blacks, Hispanics and Native American students. Working with NSBP, SACNAS, AISES and NSHP, SEC scientists were able to speak in their board meetings and national conferences, to network with minority scientists, and to engage them in Sun-Earth Day. Through these opportunities and programs, scientists have introduced NASA research results as well indigenous views of science. They also serve as role models in various communities. Since the theme for Sun-Earth Day 2005 is Ancient Observatories: Timeless Knowledge, scientists and education specialists are hopeful to excite many with diverse backgrounds. Sun-Earth Day is a highly visible annual program since 2001 that touches millions of students and the general public. Interviews, classroom activities and other education resources are available on the web at sunearthday.nasa.gov.

    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.

    2005-05-01

    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.

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

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

    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

  6. Sunwatchers Across Time: Sun-Earth Day from Ancient and Modern Solar Observatories

    Hawkins, I.; Vondrak, R.

    Humans across all cultures have venerated, observed, and studied the Sun for thousands of years. The Sun, our nearest star, provides heat and energy, is the cause of the seasons, and causes space weather effects that influence our technology-dependent society. The Sun is also part of indigenous tradition and culture. The Inca believed that the Sun had the power to make things grow, and it does, providing us with the heat and energy that are essential to our survival. From a NASA perspective, Sun-Earth Connection research investigates the effects of our active Sun on the Earth and other planets, namely, the interaction of the solar wind and other dynamic space weather phenomena with the solar system. We present plans for Sun-Earth Day 2005, a yearly celebration of the Sun-Earth Connection sponsored by the NASA Sun-Earth Connection Education Forum (SECEF). SECEF is one of four national centers of space science education and public outreach funded by NASA Office of Space Science. Sun-Earth Day involves an international audience of schools, science museums, and the general public in activities and events related to learning about the Sun-Earth Connection. During the year 2005, the program will highlight cultural and historical perspectives, as well as NASA science, through educational and public outreach events intended to involve diverse communities. Sun-Earth Day 2005 will include a series of webcasts from solar observatories produced by SECEF in partnership with the San Francisco Exploratorium. Webcasts from Chaco Culture National Historical Park in New Mexico, USA, and from Chichen Itza, Mexico, will be accessed by schools and the public. Sun-Earth Day will also feature NASA Sun-Earth Connection research, missions, and the people who make it possible. One of the goals of this talk is to inform and engage COSPAR participants in these upcoming public events sponsored by NASA. Another goal is to share best practices in public event programming, and present impact

    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.

  8. 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

    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...

  11. Sun-earth connection education through modern views of ancient

    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.

    Space weather forecasting is a focus of a multidisciplinary research effort motivated by a sensitive dependence of many modern technologies on geospace conditions. Adequate understanding of the physics of the Sun-Earth connection and associated multi-scale magnetospheric and ionospheric processes is an essential part of this effort. Modern physical simulation models such as multimoment multifluid models with effective coupling from small-scale kinetic processes can provide valuable insight into the role of various physical mechanisms operating during geomagnetic storm/substorm activity. However, due to necessary simplifying assumptions, physical models are still not well suited for accurate real-time forecasting. Complimentary approach includes data-driven models capable of efficient processing of multi-scale spatio-temporal data. However, the majority of advanced nonlinear algorithms, including neural networks (NN), can encounter a set of problems called dimensionality curse when applied to high-dimensional data. Forecasting of rare/extreme events such as large geomagnetic storms/substorms is of the most practical importance but is also very challenging for many existing models. A very promising algorithm that combines the power of the best nonlinear techniques and tolerance to high-dimensional and incomplete data is support vector machine (SVM). We have summarized advantages of the SVM and described a hybrid model based on SVM and extreme value theory (EVT) for rare event forecasting. Results of the SVM application to substorm forecasting and future directions are discussed

  14. Challenges in Modeling the Sun-Earth System

    Spann, James

    2004-01-01

    The transfer of mass, energy and momentum through the coupled Sun-Earth system spans a wide range of scales in time and space. While profound advances have been made in modeling isolated regions of the Sun-Earth system, minimal progress has been achieved in modeling the end-to-end system. Currently, end-to-end modeling of the Sun-Earth system is a major goal of the National Space Weather and NASA Living With a Star (LWS) programs. The uncertainty in the underlying physics responsible for coupling contiguous regions of the Sun-Earth system is recognized as a significant barrier to progress. Our limited understanding of the underlying coupling physics is illustrated by the following example questions: how does the propagation of a typical CME/solar flare influence the measured properties of the solar wind at 1 AU? How does the solar wind compel the dynamic response of the Earth's magnetosphere? How is variability in the ionosphere-thermosphere system coupled to magnetospheric variations? Why do these and related important questions remain unanswered? What are the primary problems that need to be resolved to enable significant progress in comprehensive modeling of the Sun-Earth system? Which model/technique improvements are required and what new data coverage is required to enable full model advances? This poster opens the discussion for how these and other important questions can be addressed. A workshop scheduled for October 8-22, 2004 in Huntsville, Alabama, will be a forum for identifying ana exploring promising new directions and approaches for characterizing and understanding the system. To focus the discussion, the workshop will emphasize the genesis, evolution, propagation and interaction of high-speed solar wind streamers or CME/flares with geospace and the subsequent response of geospace from its outer reaches in the magnetosphere to the lower edge of the ionosphere-mesosphere-thermosphere. Particular emphasis will be placed on modeling the coupling aspects

    2003-01-01

    Solar variability and solar activity are now seen as significant drivers with respect to the Earth and human technology systems. Observations over the last 10 years have significantly advanced our understanding of causes and effects in the Sun/Earth system. On a practical level the interactions between the Sun and Earth dictate how we build our systems in space (communications satellites, GPS, etc), and some of our ground systems (power grids). This talk will be about the Sun/Earth system: how it changes with time, its magnetic interactions, flares, the solar wind, and how the Sun effects human systems. Data will be presented from some current spacecraft which show, for example, how we are able to currently give warnings to the scientific community, the Government and industry about space storms and how this data has improved our physical understanding of processes on the Sun and in the magnetosphere. The scientific advances provided by our current spacecraft has led to a new program in NASA to develop a 'Space Weather' system called 'Living With a Star'. The current plan for the 'Living With a Star' program will also be presented.

  16. Challenges to modeling the Sun-Earth System: A Workshop Summary

    Spann, James F.

    2006-01-01

    This special issue of the Journal of' Atmospheric and Solar-Terrestrial Physics is a compilation of 23 papers presented at The 2004 Huntsville Modeling Workshop: Challenges to Modeling thc San-Earth System held in Huntsville, AB on October 18-22, 2004. The title of the workshop appropriately captures the theme of what was presented and discussed by the 120 participants. Currently, end-to-end modeling of the Sun-Earth system is a major goal of the National Space Weather and NASA living with a star (LWS) programs. While profound advances have been made in modeling isolated regions of the Sun-Earth system, minimal progress has been achieved in modeling the end-to-end system. The transfer of mass, energy and momentum through the coupled Sun-Earth system spans a wide range of scales inn time and space.

    2018-04-01

    The saddle points are locations where the net gravitational accelerations balance. These regions are gathering more attention within the astrophysics community. Regions about the saddle points present clean, close-to-zero background acceleration environments where possible deviations from General Relativity can be tested and quantified. Their location suggests that flying through a saddle point can be accomplished by leveraging highly nonlinear orbits. In this paper, the geometrical and dynamical properties of the Sun-Earth saddle point are characterized. A systematic approach is devised to find ballistic orbits that experience one or multiple passages through this point. A parametric analysis is performed to consider spacecraft initially on L_{1,2} Lagrange point orbits. Sun-Earth saddle point ballistic fly-through trajectories are evaluated and classified for potential use. Results indicate an abundance of short-duration, regular solutions with a variety of characteristics.

    DEFF Research Database (Denmark)

    Gopalswamy, Nat; Davila, Joseph M.; Auchère, Frédéric

    2011-01-01

    Observatory (STEREO) missions, but these missions lacked some key measurements: STEREO did not have a magnetograph; SOHO did not have in-situ magnetometer. SOHO and other imagers such as the Solar Mass Ejection Imager (SMEI) located on the Sun-Earth line are also not well-suited to measure Earth-directed CMEs....... The Earth-Affecting Solar Causes Observatory (EASCO) is a proposed mission to be located at the Sun-Earth L5 that overcomes these deficiencies. The mission concept was recently studied at the Mission Design Laboratory (MDL), NASA Goddard Space Flight Center, to see how the mission can be implemented....... The study found that the scientific payload (seven remote-sensing and three in-situ instruments) can be readily accommodated and can be launched using an intermediate size vehicle; a hybrid propulsion system consisting of a Xenon ion thruster and hydrazine has been found to be adequate to place the payload...

  19. A Small Spacecraft Swarm Deployment and Stationkeeping Strategy for Sun-Earth L1 Halo Orbits

    Science.gov (United States)

    Renea Conn, Tracie; Bookbinder, Jay

    2018-01-01

    Spacecraft orbits about the Sun-Earth librarian point L1 have been of interest since the 1950s. An L1 halo orbit was first achieved with the International Sun-Earth Explorer-3 (ISEE-3) mission, and similar orbits around Sun-Earth L1 were achieved in the Solar and Heliospheric Observatory (SOHO), Advanced Composition Explorer (ACE), Genesis, and Deep Space Climate Observatory (DSCOVR) missions. With recent advancements in CubeSat technology, we envision that it will soon be feasible to deploy CubeSats at L1. As opposed to these prior missions where one large satellite orbited alone, a swarm of CubeSats at L1 would enable novel science data return, providing a topology for intersatellite measurements of heliophysics phenomena both spatially and temporally, at varying spatial scales.The purpose of this iPoster is to present a flight dynamics strategy for a swarm of numerous CubeSats orbiting Sun-Earth L1. The presented method is a coupled, two-part solution. First, we present a deployment strategy for the CubeSats that is optimized to produce prescribed, time-varying intersatellite baselines for the purposes of collecting magnetometer data as well as radiometric measurements from cross-links. Second, we employ a loose control strategy that was successfully applied to SOHO and ACE for minimized stationkeeping propellant expenditure. We emphasize that the presented solution is practical within the current state-of-the-art and heritage CubeSat technology, citing capabilities of CubeSat designs that will launch on the upcoming Exploration Mission 1 (EM-1) to lunar orbits and beyond. Within this iPoster, we present animations of the simulated deployment strategy and resulting spacecraft trajectories. Mission design parameters such as total Δv required for long-term station keeping and minimum/maximum/mean spacecraft separation distances are also presented.

    2011-01-01

    The international solar-terrestrial physics community had recognized the importance of space weather more than a decade ago, which resulted in a number of international collaborative activities such as the Climate and Weather of the Sun Earth System (CAWSES) by the Scientific Committee on Solar Terrestrial Physics (SCOSTEP). The CAWSES program is the current major scientific program of SCOSTEP that will continue until the end of the year 2013. The CAWSES program has brought scientists from all over the world together to tackle the scientific issues behind the Sun-Earth connected system and explore ways of helping the human society. In addition to the vast array of space instruments, ground based instruments have been deployed, which not only filled voids in data coverage, but also inducted young scientists from developing countries into the scientific community. This paper presents a summary of CAWSES and other SCOSTEP activities that promote space weather science via complementary approaches in international scientific collaborations, capacity building, and public outreach.

  4. 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.

    Orbital maneuvering in a neighborhood of the collinear libration point L1 of Sun-Earth system has specific properties, primarily associated with the instability L1. For a long stay in this area of space the stabilization problem of orbital motion requires a solution. Numerical experiments have shown that for stabilization of motion it is requires very small control influence in comparison with the gravitational forces. On the other hand, the stabilization time is quite long - months, and possibly years. This makes it highly desirable to use solar pressure forces. In this paper we illustrate the solar sail possibilities for solving of stabilization problem in a neighborhood L1 with use of the model example.

Performing time of flight measurements of electromagnetic signals traveling on closed paths between the points, we show that it would be possible: (a) to refine gravitational time delay knowledge due both to the Sun and the Earth; (b) to detect the gravito-magnetic frame dragging of the Sun, so deducing information about the interior of the star; (c) to check the possible existence of a galactic gravitomagnetic field, which would imply a revision of the properties of a dark matter halo; (d) to set up a relativistic positioning and navigation system at the scale of the inner solar system. The paper presents estimated values for the relevant quantities and discusses the feasibility of the project analyzing the behavior of the space devices close to the Lagrange points.

    The formation and stability of the magnetopause current layer near the subsolar point in the sun-earth meridian plane are examined using a 2D electromagnetic particle simulation. For the case of zero IMF, the simulation results show that the current layer remains stable and is essentially the same as in the 1D simulation. The width of the current layer is given by the electron-ion hybrid gyroradius which is much smaller than the ion gyroradius. The current layer is found to remain stable for the northward IMF as well. As in the 1D simulation, the jump of the magnetic field at the current layer for the northward IMF remains small. For the southward IMF, collisionless magnetic reconnection is found to develop, leading to the formation of magnetic islands and density peaking within the current layer.

    In this paper we study the problem of constructing impulse flights between neighborhoods of unstable collinear libration points of the Sun-Earth system [1]. Such maneuvering in near-Earth space may prove to be in demand in modern space navigation. For example, such a maneuvering was done by the space vehicle GENESIS. Three test points are chosen for the implementation of the impulse control, in order to move to a neighborhood of the libration point L2. It is shown that the earlier on the exit from the vicinity of the libration point L1 impulse control was realized, the sooner the neighborhood L2 was achieved. Separated from this problem, the problem of optimal control in the neighborhood of L2 was considered and a form of stabilizing control is presented.

    Investigations of Earth's Trojan asteroids will have benefits for science, exploration, and resource utilization. By sending a small spacecraft to the Sun-Earth L4 or L5 Lagrange points to investigate near-Earth objects, Earth's Trojan population can be better understood. This could lead to future missions for larger precursor spacecraft as well as human missions. The presence of objects in the Sun-Earth L4 and L5 Lagrange points has long been suspected, and in 2010 NASA's Wide-field Infrared Survey Explorer (WISE) detected a 300 m object. To investigate these Earth Trojan asteroid objects, it is both essential and feasible to send spacecraft to these regions. By exploring a wide field area, a small spacecraft equipped with an IR camera could hunt for Trojan asteroids and other Earth co-orbiting objects at the L4 or L5 Lagrange points in the near-term. By surveying the region, a zeroth-order approximation of the number of objects could be obtained with some rough constraints on their diameters, which may lead to the identification of potential candidates for further study. This would serve as a precursor for additional future robotic and human exploration targets. Depending on the inclination of these potential objects, they could be used as proving areas for future missions in the sense that the delta-V's to get to these targets are relatively low as compared to other rendezvous missions. They can serve as platforms for extended operations in deep space while interacting with a natural object in microgravity. Theoretically, such low inclination Earth Trojan asteroids exist. By sending a spacecraft to L4 or L5, these likely and potentially accessible targets could be identified.

    An experimental, inquiry-based physical science curriculum for undergraduate, pre-service K-8 teachers is under development at the Catholic University of America in collaboration with the Solar Physics Branch of the Naval Research Laboratory and NASA's Sun-Earth Connection missions. This is a progress report. The current, stunningly successful exploratory phase in Sun-Earth Connection (SEC) physics, sparked by SOHO, Yohkoh, TRACE, and other International Solar Terrestrial Physics (ISTP) and Living With a Star (LWS) programs, has provided dynamic, visually intuitive data that can be used for teaching basic physical concepts such as the properties of gravitational and electromagnetic fields which are manifest in beautiful imagery of the astrophysical plasmas of the solar atmosphere and Earth's auroras. Through a team approach capitalizing on the combined expertise of the Catholic University's departments of Education and Physics and of NRL solar researchers deeply involved in SEC missions we have laid out a program that will teach non-science-major undergraduates a very limited number of physical science concepts but in such a way as to develop for each one both a formal understanding and an intuitive grasp that will instill confidence, spark interest and scientific curiosity and, ideally, inspire a habit of lifetime inquiry and professional growth. A three-semester sequence is planned. The first semester will be required of incoming Education freshmen. The second and third semesters will be of such a level as to satisfy the one-year science requirement for non-science majors in the College of Arts and Sciences. The approach as adopted will integrate physics content and educational methods, with each concept introduced through inquiry-based, hands-on investigation using methods and materials directly applicable to K-8 teaching situations (Exploration Phase). The topic is further developed through discussion, demonstration and lecture, introducing such mathematical

    Reaching out to Spanish speakers is increasingly vital to workforce development and public support of space science projects. Building on a successful partnership with NASA's TIMED mission, LASP and Space Science Institute, Fiske Planetarium has translated its original planetarium show - "Space Storm” - into "Tormenta Espacial". This show explores the Sun-Earth connection and explains how solar activity affects technology and life on Earth. Solar scientists from NOAA's Space Environment Center and the University of Colorado at Boulder contributed to provide scientific accuracy. Show content and accompanying educational materials are aligned with state and national science standards. While designed for students in grades 6-8, this show has been positively evaluated by students from grades 4-10 and shown to the general public with favorable responses. Curricular materials extend the planetarium experience into the K-12 classroom so that students inspired and engaged by the show continue to see real-life applications and workplace opportunities. Fiske Planetarium offers both "Space Storm” and "Tormenta Espacial” to other planetariums at a minimal rate, including technical support for the life of the show. Thanks to a request from a planetarium in Belgium, a version of "Space Storm” is available with no spoken dialogue so that languages other than English or Spanish may be accommodated. Collaborative projects among planetariums, NASA missions (planned as well as active), research scientists and other parties keep EPO activities healthy and well-funded. Fiske Planetarium staff strive to develop and maintain partnerships throughout the EPO and informal education communities.

    2015-01-01

    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.

    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 During many past decades, scientists from various countries have studied separately the atmospheric motions in the lower atmosphere, in the Earth's magnetic field, in the magnetospheric currents, etc. All of these separate studies lead today to the global study of the Sun and Earth connections, and as a consequence, new scientific programs (IHY- International Heliophysical Year, CAWSES- Climate and Weather in the Sun-Earth System are defined, in order to assume this new challenge. In the past, many scientists did not have the possibility to collect data at the same time in the various latitude and longitude sectors. Now, with the progress of geophysical sciences in many developing countries, it is possible to have access to worldwide data sets. This paper presents the particularities of geophysical parameters measured by the Vietnamese instrument networks. It introduces a cooperative Vietnamese-IGRGEA (International Geophysical Research Group Europe Africa project, and presents, for the first time, to the international community, the geophysical context of Vietnam. Concerning the ionosphere: since 1963, during four solar cycles, the ionosonde at Phu Thuy (North Vietnam was operating. The Phu Thuy data exhibits the common features for the ionospheric parameters, previously observed in other longitude and latitude sectors. The critical frequencies of the E, F1 and F2 ionospheric layers follow the variation of the sunspot cycle. F2 and E critical frequencies also exhibit an annual variation. The first maps of TEC made with data from GPS receivers recently installed in Vietnam illustrate the regional equatorial pattern, i.e. two maxima of electronic density at 15° N and 15° S from the magnetic equator and a trough of density at the magnetic equator. These features illustrate the equatorial fountain effect. Concerning the Earth's magnetic field: a strong amplitude of the equatorial electrojet was first observed by the CHAMP satellite at the height

    The purpose of this investigation is to determine the feasibility of attaining and maintaining unique non-Keplerian orbit vantage locations in the Earth/Moon environment in order to obtain continuous scientific measurements. The principal difficulty associated with obtaining continuous measurements is the temporal nature of astrodynamics, i.e., classical orbits. This investigation demonstrates advanced trajectory designs to meet demanding science requirements which cannot be met following traditional orbital mechanic logic. Examples of continuous observer missions addressed include Earth pole-sitters and unique vertical libration orbits that address Sun-Earth Connection and Earth Science Vision roadmaps.

    It is accepted that the climate on earth is changing due to a radiative energy imbalance at the top of the atmosphere, up to now this radiation imbalance has not been measured directly. The measurement is challenging both in terms of space-time sampling of the radiative energy that is leaving the earth and in terms of accuracy. The incoming solar radiation and the outgoing terrestrial radiation are of nearly equal magnitude - of the order of 340 W/m² - resulting in a much smaller difference or imbalance of the order of 1 W/m². The only way to measure the imbalance with sufficient accuracy is to measure both the incoming solar and the outgoing terrestrial radiation with the same instrument. Based on our 30 year experience of measuring the Total Solar Irradiance with the Differential Absolute RADiometer (DIARAD) type of instrument and on our 10 year experience of measuring the Earth Radiation Budget with the Geostationary Earth Radiation Budget (GERB) instrument on Meteosat Second Generation, we propose an innovative constellation of Sun-earth IMBAlance (SIMBA) radiometer cubesats with the ultimate goal to measure the Sun-earth radiation imbalance. A first Simba In Orbit Demonstration satellite is scheduled for flight with QB50 in 2015. It is currently being developed as ESA's first cubesat through an ESA GSTP project. In this paper we will give an overview of the Simba science objectives and of the current satellite and payload development status.

    The payload mass and volume capabilities of the planned Ares V launch vehicle provide the science community with unprecedented opportunities to place large science payloads into low earth orbit and beyond. One example, the outcome of a recent study conducted at the NASA Marshall Space Flight Center, is a large, monolithic telescope with a primary mirror diameter of 6.2 meters placed into a halo orbit about the second Sun-Earth Lagrange point, or L2, approximately 1.5 million kin beyond Earth's orbit. Operating in the visible and ultraviolet regions of the electromagnetic spectrum, such a large telescope would allow astronomers to detect bio-signatures and characterize the atmospheres of transiting exoplanets, provide high resolution imaging three or more times better than the Hubble Space Telescope and the James Webb Space Telescope, and observe the ultraviolet light from warm baryonic matter.

    We present a concept for a small mission to the Sun-Earth Lagrangian L5 point for innovative solar, heliospheric and space weather science. 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.

    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.

    Full Text Available A psoríase é uma doença da pele relativamente freqüente, que afeta de 1% a 3% da população geral e atinge homens e mulheres, e é mais freqüente na raça branca. Caracteriza-se pelo aparecimento na pele de lesões róseas ou avermelhadas, recobertas de escamas secas e esbranquiçadas. Muitas vezes, essas lesões estão localizadas apenas nos cotovelos, joelhos ou couro cabeludo. Em outros casos, as lesões podem se espalhar por toda a pele, atingir unhas e, raramente, as articulações, causando a artrite psoriásica. A psoríase pode ser dividida em classes: vulgar, pustulosa, artrite psiriásica e psoríase eritrodérmica.

  5. Gamma-radiation effect of the ATP-ASE-activity in various parts of cotton sprouts

    International Nuclear Information System (INIS)

    Kazimov, A.K.

    1975-01-01

    ATP-ase is a thiol enzyme whose sulfhydryl group plays an important role. The transport of substances through biological membranes is the result of the action of the sodium-potassium pump of the cell, which functions with ATP energy. The action of this transport mechanism depends on the activity of ATP-ase. It may be postulated, therefore, that the suppression of the active transport of Na + and K + ions in cells under irradiation is partially the result of a disturbance of the activity of the ATP enzyme system. The author studied the effect of gamma radiation on ATP-ase activity in various parts of seven-day-old seedlings of type 108-F cotton, which were irradiated using Co 60 gamma radiation. The results of the experiment showed that the ATP-ase activity of the cotton seedling rootlets depends on the dose and the time elapsed after irradiation (a table is given). Small radiation doses (0.2 and 0.5 krad) significantly increased ATP-ase activity in the rootlets, while heavy doses inhibited it significantly. Similar results were obtained for the stems and leaves (tables are given). It was estblished that the ATP-ase of cotton seedlings has varying sensitivity to irradiation. The most sensitive ATP-ases were those of the rootlets. The activity of background ATP-ase is less subject to change than Na + and K + activated ATP-ases. For example, while the activity of ATP-ase (without ions) was inhibited by 25% when a 25 krad irradiation dose was administered, the retardation of Na + and K + activated ATP-ases reached 41%. The author suggests that the inhibition of ATP-ase activity under irradiation is mainly the result of a disturbance of the structure of the membrane functions. It is also possible that ATP-ase activity decreases because of a lack of the enzyme substrate - ATP, which is formed during the process of oxydative phosphorylization. A table is also provided showing the effect of irradiation on the activity of ATP-ase activated by various ions in the roots of

    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 OBJETIVO: A litíase urinária é uma complicação incomum no alotransplante renal, a incidência varia de 0,02 a 3,4%. A maioria dos cálculos forma-se após o transplante, porém alguns podem ser transferidos junto com o enxerto para o hospedeiro. O tratamento desta complicação está baseado em alguns casos descritos na literatura. O objetivo deste trabalho é o de relatar a incidência da litíase renal no paciente com transplante renal, assim como a conduta adotada no HCFMRPUSP. MÉTODOS: Foram analisados 953 pacientes submetidos a transplante renal no HCFMRPUSP, de fevereiro 1968 a maio de 2003. A idade média foi de 47,2 anos (35 a 63 anos. Em 09 pacientes, o rim foi proveniente de doador cadáver e apenas 01 doador vivo. RESULTADOS:Foram diagnosticados 10 casos de litíase (1,05%. Em 02 pacientes (20% o cálculo foi diagnosticado no intraoperatório, em 01 (10% no peri-operatório (5º. dia, os 07 restantes (70% no pós-operatório tardio. Em 04 pacientes (57% não havia sintomatologia específica, 02 (29% apresentaram ITU, em 03 (43% ocorreu elevação da creatinina sérica. De 8 pacientes com litíase no pós-operatorio, em 06 os cálculos estavam localizados no rim e 02 no ureter. Dos pacientes com cálculos renais, 02 foram observados, 02 submetidos a LECO, 01 a nefrolitripsia percutânea, 01 à pielolitotomia. Em 01 paciente com cálculo ureteral foi realizada pielovesicostomia (cálculo + estenose, no outro paciente foi feita a ureterorrenoscopia retrógrada. CONCLUSÃO: A urolitíase é complicação rara no transplante renal, a conduta terapêutica no pós-operatório tardio é semelhante à da população geral.

    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 response of broiler chickens to 3 levels of sunflower meal and 2 levels of NSP-ase enzyme combination (with and without) was investigated in 3 × 2 factorial arrangement under complete randomized design (CRD). A total of 240 Hubbard broiler chicks were fed on practical mash diets having 2950 kcal of ME and 21% CP from 1 to 42 days of age. The BW gain was not significantly reduced when 25% SFM was added in the diets during 1 to 42 days of age. Supplementation of NSP-ase in broiler diets (day 1-42 overall) demonstrated non-significant differences (p Replacement of SBM with SFM or inclusion of SFM at higher level (25%) increased/deteriorated FCR. The addition of exogenous NSP-ase showed a significant improvement (p < 0.01) in feed:gain. The improvement was clearly demonstrated when SFM was added to the experimental diet at 15% or even 20%. Supplementation of NSP-ase at the 25% inclusion level could not, however, sustain the beneficial effect, which was possibly due to excessively high dietary CF. No difference was noted across the treatments regarding carcass response. Relative gizzard weight and intestinal weight were observed to be improved in birds consuming higher levels of SFM (p = 0.00). The digestibility of CF was observed to improve when SFM was used at 20% and 25% in the diets. No improvement in the digestibility of CF was observed with NSP-ase supplementation, which meant other factors were clearly involved. Supplementation of NSP-ase improved FCR up to 20% SFM. At 25% SFM, no improvement in the digestibility of CF was observed with NSP-ase supplementation. Journal of Animal Physiology and Animal Nutrition © 2016 Blackwell Verlag GmbH.

    The influence of the post-radiation factor helping the restoration of radiation damages in the early sorts of cotton plant 1306'DV Goss. hirsutum was studied. In particular the action of treating the irradiated seed in the solution of calcium salts on the functional state of alcaline and acid forms of nucleases in cellular components was investigated. The dry seed of cotton was irradiated with gamma-rays at dose of 30 krad. It was found that irradiation of the dry seed at the radiosensitive organ (roots) increased the acid DNA-ase in the cellular nuclei, in the radioresistant (leaves) - the alcaline DNA-ase and RNA-ase. With irradiation both forms of DNA-ase in the mitochondriae diminished. After treatment of the irradiated seed in the solution of calcium salts the activity of acid nucleases and alcaline enzymes remained normal

  3. Platelet activating factor-acylhydrolase (PAF-ase) activity is higher in serum of men than women and is related to levels of low density lipoprotein (LDL)

    1986-01-01

    PAF-ase is a specific serum enzyme that inactivates PAF by hydrolyzing acetate from the sn-2 position of the glycerol backbone. A reproducible PAF-ase activity assay was developed. A unit is based on the amount of serum required to release 3.61 +/- 0.042 pm 3 H-acetate from 10 pm 3 H-labeled PAF after incubation for 1 hr at 37 0 C. Assays on two single reference serums repeated 7 days were 0.63 +/- 0.013 U and 1.33 +/- 0.031 U. Serum from 20 normal men and 20 normal premenopausal women had significantly different (p = <0.001) levels of 1.32 +/- 0.072 U and 0.97 +/- 0.051 U respectively. They previously reported that PAF-ase is associated with B-lipoprotein. Therefore, total cholesterol (TC), LDL and high density lipoproteins (HDL) were determined on these 40 serums. Regression analysis revealed PAF-ase units were correlated with LDL (r = 0.740; p = < 0.001) and, parenthetically, with the TC (r = 0.620; p = < 0.001) but not with HDL. These correlations were similar for men and women. Thus, serum PAF-ase was partially controlled by serum LDL levels and the higher PAF-ase levels in serum from men were due in part to higher (p = < 0.01) LDL levels in men (147.6 +/- 6.9 mg/dl) as contrasted to women (119.0 +/- 7.6 mg/dl). PAF is a potent inflammatory, bronchoconstrictive and hypotensive agent. These data indicate that sex and serum LDL levels of subjects must be considered during future studies of the role of PAF vs PAF-ase in different disease states

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

    Directory of Open Access Journals (Sweden)

    Lorenzo Iorio

    2013-10-01

    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.

    2011-11-01

    OBJECTIVES. Dissatisfaction with services has been associated with poorer child mental health outcomes, early treatment termination as well as disagreements over the nature of mental health difficulties, reasons for referral and therapy goals. The development of straightforward, reliable, and accurate methods of eliciting service users' views is essential within child and adolescent mental health care. This paper describes the development of the child and adolescent service experience (ChASE), a tool to measure children and young people's service experience DESIGN. The study comprises a non-experimental, cross-sectional design. METHODS. Participants were 132 mental health service users aged 8-18 years. Participants and their main carer completed the ChASE, Parent Satisfaction Questionnaire (PSQ) (Stallard, 1996) and Strengths and Difficulties (SDQ) Impact Supplement. Clinicians completed the SDQ Impact Supplement and provided clinical activity data. A sub-sample of participants completed the ChASE on a second occasion, 6 weeks after the completion of the first questionnaire. RESULTS. Scrutiny of ChASE data indicated high levels of completion. Principal axis factoring identified three factors within the ChASE: Relationship, Privacy, and Session Activity. The ChASE has good internal consistency and test-retest reliability. Significant correlations were found between the ChASE and carer satisfaction, service use, and youth clinical outcomes. CONCLUSIONS. The ChASE is a short, psychometrically robust tool for routine measurement of children, and young people's experience of mental health services, which users can complete easily. The results underline the importance of alliance factors to children and young people and their association with clinical improvement as well as the potential for the ChASE to be used a measure of children's therapeutic progress and alliance. ©2011 The British Psychological Society.

    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

    This report presents the essential features and highlights of the 1998 Summer Faculty Fellowship Program at Ames Research Center and Dryden Flight Research Center in a comprehensive and concise form. Summary reports describing the fellows' technical accomplishments are enclosed in the attached technical report. The proposal for the 1999 NASA-ASEE-Stanford Summer Faculty Fellowship Program is being submitted under separate cover. Of the 31 participating fellows, 27 were at Ames and 4 were at Dryden. The Program's central feature is the active participation by each fellow in one of the key technical activities currently under way at either the NASA Ames Research Center or the NASA Dryden Flight Research Center. The research topic is carefully chosen in advance to satisfy the criteria of: (1) importance to NASA, (2) high technical level, and (3) a good match to the interests, ability, and experience of the fellow, with the implied possibility of NASA-supported follow-on work at the fellow's home institution. Other features of the Summer Faculty Fellowship Program include participation by the fellows in workshops and seminars at Stanford, the Ames Research Center, and other off-site locations. These enrichment programs take place either directly or remotely, via the Stanford Center for Professional Development, and also involve specific interactions between fellows and Stanford faculty on technical and other academic subjects. A few, brief remarks are in order to summarize the fellows' opinions of the summer program. It is noteworthy that 90% of the fellows gave the NASA-Ames/Dryden- Stanford program an "excellent" rating and the remaining 10%, "good." Also, 100% would recommend the program to their colleagues as an effective means of furthering their professional development as teachers and researchers. Last, but not least, 87% of the fellows stated that a continuing research relationship with their NASA colleagues' organization probably would be maintained. Therefore

Although the influence of many factors that are assumed to be fixed (ceteris paribus are very strong-such as macroeconomic variables GDP, economic growth and inflation, they left various conclusions and debates. FDI can be one of the important sources of capital in developing countries, and contribute, the national development by transfer of asset, management, and technology to stimulate the economy of the country. The research model uses some domestic characteristics, that will be combined in a short and long run period by using OLS. The Error Correction Model (ECM and Granger Causality Test, are applied to the determine the factors that influence the foreign direct investment (FDI in Indonesia within 1978 -2001. The result shows that economic variables such as GDP, growth, wage and export have positive effect to FDI. While non-economic variables such as Political Stability (SP shows a negative effect. This conclusion is in a harmony with the empirical study done by Schneider and Frey (1986 that politicaal stability has a negative relations ship with FDI.

    2014-09-01

    Differential scanning calorimetry was used to study the crystallization behaviour of selenium thin films in dependence on film thickness and deposition rate. In the current work, which is the fourth in a sequence of articles dealing with crystallization kinetics of a-Se, the non-isothermal crystallization kinetics was described in terms of the Johnson-Mehl-Avrami nucleation-growth model. Two-dimensional crystallite growth, consistent with the idea of sterically restricted crystallization in a thin layer, was confirmed for all data. It was found that neither the film thickness (tested within the 100-2350 nm range) nor the deposition rate appears to have any significant influence on the crystallization kinetics. However, the higher amount of intrinsic defects possibly produced by a higher deposition rate seems to accelerate the crystallization, shifting it towards lower temperatures. Very good correlation between the results obtained for thin films and those for fine powders was found. Based on the obtained results, interpretations of relevant literature data were made.

    We examined the meaning of living with HIV/AIDS among women in Lebanon. Ten women living with HIV/AIDS (WLWHA) described their experiences via semistructured in-depth interviews. They navigated a process of HIV diagnosis acceptance that incorporated six overlapping elements: receiving the news, accessing care, starting treatment, navigating disclosure decisions, negotiating stigma, and maintaining stability. Through these elements, we provide a framework for understanding three major themes that were constructed during data analysis: Stand by my side: Decisions of disclosure; Being “sick” and feeling “normal”: Interacting with self, others, and society; and Living day by day: focusing on the present. We contribute to the existing literature by providing a theoretical framework for understanding the process of diagnosis and sero-status acceptance among WLWHA.

    2016-04-18

    We study the field-of-view (FOV) of an upconversion imaging system that employs an Amplified Spontaneous Emission (ASE) fiber source to illuminate a transmission target. As an intermediate case between narrowband laser and thermal illumination, an ASE fiber source allows for higher spectral intensity than thermal illumination and still keeps a broad wavelength spectrum to take advantage of an increased non-collinear phase-matching angle acceptance that enlarges the FOV of the upconversion system when compared to using narrowband laser illumination. A model is presented to predict the angular acceptance of the upconverter in terms of focusing and ASE spectral width and allocation. The model is experimentally checked in case of 1550-630 nm upconversion.

    Detection of pancreas necrosis was attempted in dog experiments. Strong association between pancreatic DNA-ase and actin molecules in vitro provided the theoretical basis for the procedure. Pancreatic DNA-ase labelled with 125 I was administered intravenously to dogs in which experimental pancreas necrosis was elicited. Accumulation ratio of radioactivity was above 20 in the necrotic pancreas whereas it varied between 1.6 and 5.6 in other tissues. After administration of 37 MBq 131 I labelled DNA-ase, accumulation of radioactivity could be clearly visualized in the necrotic portions of the removed pancreas by a gamma camera. The investigations will be extended in order to develop a clinically utilizable test. (L.E.)

    NASA's STEREO/IMPACT Mission includes an Education and Public Outreach component that seeks to offer national programs for broad audiences highlighting the mission's solar and geo-space research. In an effort to make observations of the Sun more accessible and exciting for a general audience, we look for alternative ways to represent the data. Scientists most often represent data visually in images, graphs, and movies. However, any data can also be represented as sound audible to the human ear, a process known as sonification. We will present our plans for an exciting prototype program that converts the science results of solar energetic particle data to sound. We plan to make sounds, imagery, and data available to the public through the World Wide Web where they may create their own sonifications, as well as integrate this effort to a science museum kiosk format. The kiosk station would include information on the STEREO mission and monitors showing images of the Sun from each of STEREO's two satellites. Our goal is to incorporate 3D goggles and a headset into the kiosk, allowing visitors to see the current or archived images in 3D and hear stereo sounds resulting from sonification of the corresponding data. Ultimately, we hope to collaborate with composers and create musical works inspired by these sounds and related solar images.

    The problem of shock waves, caused by solar activity in the Earth's magnetosphere and its magnetic field, is discussed. All types of shock waves have their origin either in solar corona effects or in solar eruptions. Ionospheric and magnetospheric effects, such as X and gamma radiation, particle production, geomagnetic storms and shock waves, caused by solar activity, are dealt with and attempts are made to explain their interdependence. The origin and propagation of coronal shock waves, interplanetary shock waves and geomagnetic field disorders are described and their relations discussed. The understanding of the solar corona and wind phenomena seems to allow prediction of geomagnetic storms. The measurement and analysis of solar activity and its effects could yield useful information about shock waves physics, geomagnetosphere structure and relations between the Earth and the Sun.

    The quantum yield for light-induced H2 generation was measured for a previously optimized bio-hybrid cytochrome c 6-crosslinked PSI(C13G)-1,8-octanedithiol-[FeFe]-H2ase(C97G) (PSI-H2ase) nanoconstruct. The theoretical quantum yield for the PSI-H2ase nanoconstruct is 0.50 molecules of H2 per photon absorbed, which equates to a requirement of two photons per H2 generated. Illumination of the PSI-H2ase nanoconstruct with visible light between 400 and 700 nm resulted in an average quantum yield of 0.10-0.15 molecules of H2 per photon absorbed, which equates to a requirement of 6.7-10 photons per H2 generated. A possible reason for the difference between the theoretical and experimental quantum yield is the occurrence of non-productive PSI(C13G)-1,8-octanedithiol-PSIC13G (PSI-PSI) conjugates, which would absorb light without generating H2. Assuming the thiol-Fe coupling is equally efficient at producing PSI-PSI conjugates as well as in producing PSI-H2ase nanoconstructs, the theoretical quantum yield would decrease to 0.167 molecules of H2 per photon absorbed, which equates to 6 photons per H2 generated. This value is close to the range of measured values in the current study. A strategy that purifies the PSI-H2ase nanoconstructs from the unproductive PSI-PSI conjugates or that incorporates different chemistries on the PSI and [FeFe]-H2ase enzyme sites could potentially allow the PSI-H2ase nanoconstruct to approach the expected theoretical quantum yield for light-induced H2 generation.

    All-optical regenerators can be used to suppress amplified spontaneous emission (ASE) noise introduced by cascaded erbium doped fiber amplifiers (EDFAs) in optical fiber communication systems and lead to the improvement of optical receiver sensitivity. By introducing the Q-factor transfer function (QTF), we evaluate the Q-factor performance of degenerate four-wave mixing (DFWM) regenerators with clock pump and reveal the differences between the optimal input powers determined from the static and dynamic power tranfer function (PTF) and the QTF curves. Our simulation shows that the clock-pump regnerator is capable of improving the Q-facor and receiver sensitivity for 40 Gbit/s ASE-degraded return-to-zero on-off keying (RZ-OOK) signal by 2.58 dB and 4.2 dB, respectively.

Optical properties of these films were obtained from the UV-VIS transmission spectra, at normal incidence, over 200-1100 nm spectral range. The optical absorption edge was described by using the model given by the Tauc. Optical band gap of the deposited films was calculated using Tauc plot. Optical characterization showed that average transmission and optical band gap decreased with the addition of antinomy.

    Full Text Available Cálculos vesicais são raros e a maioria dos casos ocorre em homens adultos com obstrução infravesical. Atualmente, existem poucos dados sobre o melhor tratamento desta doença. O objetivo desta revisão foi discutir alguns aspectos da patogênese e abordar o tratamento da litíase vesical. Uma ampla pesquisa na base de dados da "National Library of Medicine"/Pubmed foi realizada com os seguintes unitermos e descritores: vesical ou bexiga associados a cálculo, pedra ou litíase, e cistolitotripsia. Cento e setenta e um artigos foram identificados. Os artigos foram avaliados independentemente por dois revisores com experiência em urolitíase. Foram incluídos quando os resultados, complicações e seguimento foram claramente reportados. No final, 32 estudos preencheram os critérios de inclusão. Nota-se que diversas opções para o tratamento da litíase vesical estão disponíveis, porém não há estudos randomizados comparando-as. Diferentes taxas de pacientes livres de cálculo são descritas, sendo: litotripsia extracorpórea com ondas de choque (75-100%, cistolitotripsia transureteroscópica (63-100%, cistolitotripsia percutânea (89-100% e cirurgia aberta (100%. O acesso percutâneo apresenta menor morbidade com resultados semelhantes ao tratamento transuretral, enquanto a litotrispsia extracorpórea apresenta as menores de taxas de eliminação de cálculos e fica reservada aos pacientes de alto risco cirúrgico.

  16. Pulse distortion, energy extraction, and ASE in an HF amplifier with angular multiplexing

    International Nuclear Information System (INIS)

    McGuire, E.J.

    1976-09-01

    It has been proposed that 1 ns pulses can be efficiently extracted from the e-beam initiated HF laser by angular multiplexing, i.e., filling the amplifier with the 1 ns pulses, 1 ns apart in time, each pulse at a slightly different angle; each pulse has an input intensity of 1 W/cm 2 per line and almost fills the amplifier. We have treated this in a one dimensional model, neglecting transverse amplified spontaneous emission. We conclude that the scheme is efficient, and that most of the pulses are amplified but not distorted. The first few pulses are distorted by transient effects and the last pulse has an enhanced tail. The ratio of peak pulse intensity to forward ASE at the output is 10 4 . We then include transverse ASE and find a drastically different situation. ASE saturates the inversion after a short time depending on pulse intensity (4 ns at I/sub o/ = 1 W/cm 2 , 7 ns at I/sub o/ = 100 W/cm 2 ). The saturation time is only weakly dependent on the transverse reflection coefficient. Calculations were done on an amplifier system designed for 10 KJ output. At an incident peak pulse intensity of 10 4 W/cm 2 -line (.77 MW/cm 2 for 77 lines) 2.5 KJ was obtained in amplified pulse energy, i.e., only 6 pulses of the 24 pulse train were fully amplified. The calculations indicate that double passing the pulse train through the amplifier would enhance the energy extracted

  20. Accelerated solvent extraction (ASE) - a fast and automated technique with low solvent consumption for the extraction of solid samples (T12)

    International Nuclear Information System (INIS)

    Hoefler, F.

    2002-01-01

    Full text: Accelerated solvent extraction (ASE) is a modern extraction technique that significantly streamlines sample preparation. A common organic solvent as well as water is used as extraction solvent at elevated temperature and pressure to increase extraction speed and efficiency. The entire extraction process is fully automated and performed within 15 minutes with a solvent consumption of 18 ml for a 10 g sample. For many matrices and for a variety of solutes, ASE has proven to be equivalent or superior to sonication, Soxhlet, and reflux extraction techniques while requiring less time, solvent and labor. First ASE has been applied for the extraction of environmental hazards from solid matrices. Within a very short time ASE was approved by the U.S. EPA for the extraction of BNAs, PAHs, PCBs, pesticides, herbicides, TPH, and dioxins from solid samples in method 3545. Especially for the extraction of dioxins the extraction time with ASE is reduced to 20 minutes in comparison to 18 h using Soxhlet. In food analysis ASE is used for the extraction of pesticide and mycotoxin residues from fruits and vegetables, the fat determination and extraction of vitamins. Time consuming and solvent intensive methods for the extraction of additives from polymers as well as for the extraction of marker compounds from herbal supplements can be performed with higher efficiencies using ASE. For the analysis of chemical weapons the extraction process and sample clean-up including derivatization can be automated and combined with GC-MS using an online ASE-APEC-GC system. (author)

Porém, houve variação com o tempo de acompanhamento de cada indivíduo, sendo de 0,06385 ao final do primeiro ano, de 0,03299 ao final do segundo, 0,02370 ao final do terceiro, 0,018622 ao final do quarto e 0,01694 ao final do período. Foi especificado um modelo de regressão logística para os indivíduos acompanhados nos primeiros cinco anos, envolvendo 758 contatos, incluindo nessa situação os casos co-prevalentes. O risco de incidência de hanseníase está relacionado com a negatividade do teste de Mitsuda, com OR de 3,093 (IC95% = 1,735-5,514, com a vacinação pelo BCG, OR de 0,3802 (IC95% = 0,2151-0,66719, e com a forma multibacilar do caso-índice, OR de 2,547 (IC95% = 1,249-5,192. Os resultados indicam que a incidência da hanseníase em contatos está associada à forma multibacilar da doença e aos fatores imunes dos contatos.

    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.

    Full Text Available Durante o curso da hanseníase, o edema comumente descrito como um sintoma de estados reacionais, pode ocorrer. 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.

  20. Performance of the 2-D asynchronous OCDMA system with ASE light sources

    2005-09-01

    The wavelength-hopping/time-spreading scheme for optical code-division multiple-access (OCDMA), also known as the 2-D scheme, has been studied by many researchers for more than a decade. In all of previous analyses, the light sources were modeled as perfectly incoherent, which requires infinite bandwidth, and chip-synchrony was assumed for mathematical simplicity. Therefore, it is important to study how the system actually performs with true asynchrony and practical light sources. The amplified spontaneous emission (ASE) source is a desirable source for the incoherent OCDMA system because of its broad bandwidth, large power, and low cost. In this paper, each chip generated by the transmitter is a rectangular ASE pulse with a Gaussian-distributed electrical field. The coherence time is much smaller than the chip duration, but non-zero. Because of this partial coherence of the light source, beat noise will occur when multiple pulses are combined. In addition, interfering pulses may only partially overlap with the pulses from the desired user due to the asynchrony, which introduces more randomness into the decision statistic. Both factors are taken into account when the distribution of the decision statistic is derived mathematically. Simulations of the bit-error rate (BER) are performed, and the results show that the coherence time may be the major limiting factor on the system performance. For example, when the coherence time is only 1/100 of the chip duration, the BER is 1-4 orders of magnitude worse than that of the ideal case.

MÉTODO: estudo transversal, com amostra de conveniência, envolvendo todas as trabalhadoras (135 de uma indústria de confecção em Criciúma (SC, sintomáticas e assintomáticas, no período de julho a setembro de 2002. Foi utilizada, como técnica de coleta dos dados, entrevista roteirizada investigando-se possíveis fatores de risco. O exame ginecológico detectou a presença ou não de sinais clínicos de vulvovaginites. Realizou-se cultura de secreção vaginal em meio de ágar Sabouraud para isolamento de Candida sp. Os dados foram processados e analisados no programa Epi-Info, versão 6.0. A medida de intensidade de associação usada foi a razão de prevalência. O intervalo de confiança adotado para inferência estatística foi de 95%. A análise multivariada dos dados foi realizada pelo programa SPSS versão 10.0, empregando-se modelo de regressão logística. RESULTADOS: os resultados mostraram que a prevalência da candidíase vulvovaginal foi de 19,3%. A freqüência de vulvovaginite diagnosticada pelo exame clínico foi de 17%, com sensibilidade de 38% e especificidade de 88%. O fator de risco significante para vulvovaginite por Candida nessa população foi a presença de ciclos menstruais regulares e para vulvovaginite clínica foi o uso de hormônios e idade entre 25 e 34 anos. CONCLUSÃO: a prevalência de candidíase vulvovaginal é alta entre mulheres consideradas hígidas e o fator de risco encontrado com significância estatística foi a presença de ciclos menstruais regulares, reforçando a importância de possível relação entre ciclo hormonal e esta infecção. Devido à limitação do presente estudo, esta possível associação, juntamente com outras, devem ser estudadas num futuro desenho de coorte com amostra de tamanho apropriado e medidas de níveis hormonais ao longo

    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.

  1. SAIL: Summation-bAsed Incremental Learning for Information-Theoretic Text Clustering.

    Information-theoretic clustering aims to exploit information-theoretic measures as the clustering criteria. A common practice on this topic is the so-called Info-Kmeans, which performs K-means clustering with KL-divergence as the proximity function. While expert efforts on Info-Kmeans have shown promising results, a remaining challenge is to deal with high-dimensional sparse data such as text corpora. Indeed, it is possible that the centroids contain many zero-value features for high-dimensional text vectors, which leads to infinite KL-divergence values and creates a dilemma in assigning objects to centroids during the iteration process of Info-Kmeans. To meet this challenge, in this paper, we propose a Summation-bAsed Incremental Learning (SAIL) algorithm for Info-Kmeans clustering. Specifically, by using an equivalent objective function, SAIL replaces the computation of KL-divergence by the incremental computation of Shannon entropy. This can avoid the zero-feature dilemma caused by the use of KL-divergence. To improve the clustering quality, we further introduce the variable neighborhood search scheme and propose the V-SAIL algorithm, which is then accelerated by a multithreaded scheme in PV-SAIL. Our experimental results on various real-world text collections have shown that, with SAIL as a booster, the clustering performance of Info-Kmeans can be significantly improved. Also, V-SAIL and PV-SAIL indeed help improve the clustering quality at a lower cost of computation.

    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.

Relatamos o caso de uma paciente do sexo feminino, de 26 anos, cujo diagnóstico foi confirmado com base nos achados marcantes na radiografia de tórax e tomografia computadorizada de alta resolução. A paciente, gestante de 28 semanas, retornou ao hospital 10 meses após o diagnóstico apresentando insuficiência respiratória hipoxêmica e com distúrbio ventilatório restritivo grave à espirometria. Após completadas 32 semanas e 4 dias de gestação, foi submetida aparto cesariano, com sucesso para mãe e filha. A MAP tem evolução clínica variável. Tem provável caráter autossômico recessivo e associação com história familiar positiva. A etiologia é incerta, e muitos autores especulam que haja um defeito enzimático local responsável pelo acúmulo intra-alveolar de cálcio. Relatos de pacientes com MAP que engravidaram são excepcionais, sendo o presente caso o primeiro descrito no Brasil. O curso dessa doença costuma ser lentamente progressivo, e os pacientes geralmente falecem devido à insuficiência cardiorrespiratória. O presente caso ilustra a necessidade de se oferecer aconselhamento genético e orientações sobre o risco de gravidez às pacientes, especialmente em casos de doença avançada.

    Full Text Available Background: It is known that Na+,K+-ATP-ase plays important role in physiology of spermatozoa including their motility. Na+,K+-ATP-ase is one of the targets for reactive oxygen species. Hyperproduction of reactive oxygen species can damage sperm cells and it is considered to be as one of the mechanisms of male infertility. Objectives: To evaluate the H2O2 effect on the main kinetic parameters of ATP hydrolysis by ouabain-sensitive Na+,K+-ATPase of spermatozoa of fertile (normozoospermia and infertility men (asthenozoospermia. Materials and methods: Na+, K+-ATP-ase activity was determined spectrophotometrically by production of Pi. Concentration dependencies ware linearized in Lineweaver-Burk plot. Results: Effective inhibitory effect of H2O2 on ouabain-sensitive Na+,K+-ATP-ase activity of sperm cells of fertile and infertile men was demonstrated. The effects of H2O2 on the main kinetic parameters of the ATP hydrolysis with the involvement of Na+, K+-ATP-ase was studied. In the whole range of studied concentrations of ATP the Na+, K+-ATP-ase activity of spermatozoa of fertile and infertile men was reduced in the presence of H2O2 in the incubation medium. However, the optimal activity of the Na+, K+-ATP-ase activity of sperm cells in both normozoospermic and asthenozoospermic men was observed in the presence of 5 mM ATP in the incubation medium. By linearization of concentration curves in Lineweaver-Burk plot the main kinetic parameters of Na+, K+-activated, Mg2+-dependent ATP hydrolysis in the sperm cells of fertile and infertile men were determined. Under the effect of H2O2, the affinity constant of enzyme to ATP in normozoospermic and asthenozoospermic men increases several times. The initial maximum rate of ATP hydrolysis was significantly reduced only in the spermatozoa of fertile men with normozoospermia. Conclusions: Under conditions of H2O2-induced oxidative stress the inhibition of ouabain-sensitive Na+,K+-ATP-ase activity in sperm cells

    2009-01-01

    Since lipids are depleted in 13 C relative to proteins and carbohydrates, variations in lipid composition among species and within individuals significantly influence δ 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 δ 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 δ 13 C values without interfering with δ 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 δ 13 C and δ 15 N variability.

    Purpose: A retrospective clinical-histological study to determine the diagnostic accuracy using high-resolution digital phosphor storage plates (CR) (hardcopy) and full-field digital mammography (DR) (hardcopy) for microcalcifications and focal lesions (BI-RADS category 4 or 5) (n=100). Materials and Methods: From 01/2004 to 06/2004, 100 patients underwent digital storage plate mammography (CR) and, after diagnosis and preoperative wire localization, full-field digital mammography (a-Se) (DR) with the same exposure parameters. Five investigators retrospectively determined the diagnosis after the operation from randomly distributed mediolateral views (hardcopy reading). These results were correlated with the final histology. Results: The accuracy of digital storage plate mammography (CR) and full-field digital mammography (DR) was 73% and 76% for all findings (n=100), 74%, 78% for microcalcifications (n=50) and 72%, 74% for focal lesions (n=50). The overall results showed no difference. Conclusion: Our findings indicate equivalence of high-resolution digital phosphor storage plate mammography (CR) and full-field digital mammography (a-Se) (DR). (orig.)

    We report an image wavelength upconversion system. The system mixes an incoming image at around 1550 nm (eye-safe region) illuminated by an amplified spontaneous emission (ASE) fiber source with a Gaussian beam at 1064 nm generated in a continuous-wave diode-pumped Nd(3+):GdVO(4) laser. Mixing takes place in a periodically poled lithium niobate (PPLN) crystal placed intra-cavity. The upconverted image obtained by sum-frequency mixing falls around the 631 nm red spectral region, well within the spectral response of standard silicon focal plane array bi-dimensional sensors, commonly used in charge-coupled device (CCD) or complementary metal-oxide-semiconductor (CMOS) video cameras, and of most image intensifiers. The use of ASE illumination benefits from a noticeable increase in the field of view (FOV) that can be upconverted with regard to using coherent laser illumination. The upconverted power allows us to capture real-time video in a standard nonintensified CCD camera.

    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

    The presence of a natural inhibitor of DNAase 1 of protein nature is responsible for the inhibiting action of blood serum on pancreatic DNAase. Depending on the radiation dose (ranging from 450 to 750 R), the activity of the serum inhibitor of DNAase 1 increases for a short time, then, in the period from 15 minutes to 24 hours, it normalizes (450 R) or drastically decreases on the seventh day (750 R). At the dose of 750 R, the activity of free serum DNAase 1 increases throughout the entire period of the experiment; the activity of bound DNAase 1 gradually decreases and it is not observed on the seventh day. The dose of 450 R does not substantially affect the activity of free DNAase 1. Evidently, at high X-ray doses, formation of the inhibitor-serum DNAase 1 complex is disturbed

    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.

  5. X-ray effects on the activity of a Mg2+-dependent, Na+- and K+-activable microsomal membrane ATP-ase system

    Froehlich, D.

    1978-01-01

    The bahviour of a Mg 2+ -dependent, Na + - and K + -activable ATP-ase sytem on irradiation was investigated using a microsome fraction of guinea pig myocardial cells prepared by fractionated centrifugation. The Na + - and K + -activable component, transport-ATPase, was particularly radiation-sensitive. Three stages of development were observed for a 1,500 R radiation damage until 24 h p.r.. In the first stage, until 30 minutes p.r., the activity of transport-ATP-ase was inhibited. This was followed by repair processes which had reached a peak value clearly higher than the control values at 4 hours p.r.. In the third stage, the activity was reduced again; 15 and 24 hours after termination of exposure, values again were nearly the same as after 30 minutes where a maximum was observed for this radiation dose. Radiation-induced electrolyte displacements, active transport, and radiation-induced inhibition of transport-ATP-ase were correlated and discussed; the assumption was that changes in, the electrolyte conditions in the membranes on irradiation are at least partly due to the described inhibition of transport-ATP-ase.

    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.

    1999-09-01

    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.

    Full Text Available This paper discusses the historical background and significance of the two most important national holidays in New Zealand: Waitangi Day and Anzac Day. Waitangi Day is celebrated on the 6th February and it commemorates the signing of the Treaty of Waitangi between British representatives and a number of Māori chiefs in 1840. Following the signing of the treaty New Zealand became effectively a British colony. Anzac Day is celebrated on 25th April, i.e., on the anniversary of the landing of soldiers of the Australian and New Zealand Army Corps (ANZAC on the Gallipoli peninsula in Turkey in 1915, during World War One. There are three major differences between these two holidays: the process of those days becoming national holidays, the level of contestation, and the changing messages they have carried. The present study analyzes the national discourse around Anzac Day and Waitangi Day in New Zealand, and attempts to reveal how the official New Zealand government rhetoric about national unity becomes deconstructed. The following analysis is based on a selection of online articles from the New Zealand Herald and Stuff published in Auckland and Wellington, respectively. Both cities are populated by multi-ethnic groups, with Auckland featuring the largest Māori population.

  10. Conformational changes in DNA caused by DNA-ase I, gamma and ultraviolet radiation as revealed by differential pulse polarography

    Vorlickova, M.

    1979-01-01

    The height, potential and half width of differential pulse-polarographic peaks of DNA were investigated in dependence on degradation by DNA-ase I and gamma and UV radiation. It was found that in all cases studied growth of peak II (reflecting conformational changes in the DNA double helix) was limited, and only after it reached a certain height further degradation induced the appearance of peak III of single-stranded DNA. This course is explained as reflecting the limited extent of conformational changes in the framework of the double helix, which probably follows from a limited number of sites that can undergo certain types of conformational changes. The character of the conformational changes is dependent on the chemical nature of the damage. (author)

    2009-01-01

    A particular periodic orbit in the Earth-Sun circular restricted three body problem is shown to have the characteristics needed for a ballistic lunar capture transfer. An injection from a circular parking orbit into the periodic orbit serves as an initial guess for a targeting algorithm. By targeting appropriate parameters incrementally in increasingly complicated force models and using precise derivatives calculated from the state transition matrix, a reliable algorithm is produced. Ballistic lunar capture trajectories in restricted four body systems are shown to be able to be produced in a systematic way.

    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.

  6. 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.

    The aim of the current study was to validate the self-report section of the American Shoulder and Elbow Surgeons questionnaire (ASES-p) into Spanish. Shoulder pathology patients were recruited and followed up to 6 months post treatment. The ASES-p, Constant, SF-36 and Barthel scales were filled-in pre and post treatment. Reliability was tested with Cronbach's alpha, convergent validity with Spearman's correlations coefficients. Confirmatory factor analysis (CFA) and the Rasch model were implemented for assessing structural validity and unidimensionality of the scale. Models with and without the pain item were considered. Responsiveness to change was explored via standardised effect sizes. Results were acceptable for both tested models. Cronbach's alpha was 0.91, total scale correlations with Constant and physical SF-36 dimensions were >0.50. Factor loadings for CFA were >0.40. The Rasch model confirmed unidimensionality of the scale, even though item 10 "do usual sport" was suggested as non-informative. Finally, patients with improved post treatment shoulder function and those receiving surgery had higher standardised effect sizes. The adapted Spanish ASES-p version is a valid and reliable tool for shoulder evaluation and its unidimensionality is supported by the data.

    Using the ASED-MO (Atom Superposition and Electron Delocalization-Molecular Orbital) theory, we investigated carbon formation and carbon hydrogenation for CO_2 methanation on the Ni (111) surface. For carbon formation mechanism, we calculated the following activation energies, 1.27 eV for CO_2 dissociation, 2.97 eV for the CO, 1.93 eV for 2CO dissociation, respectively. For carbon methanation mechanism, we also calculated the following activation energies, 0.72 eV for methylidyne, 0.52 eV for methylene and 0.50 eV for methane, respectively. We found that the calculated activation energy of CO dissociation is higher than that of 2CO dissociation on the clean surface and base on these results that the CO dissociation step are the ratedetermining of the process. The C-H bond lengths of CH_4 the intermediate complex are 1.21 A, 1.31 A for the C···H_(_1_), and 2.82 A for the height, with angles of 105 .deg. for H_(_1_)CH and 98 .deg. for H_(_1_)CH_(_1_)

    Full Text Available BACKGROUND: assessment instruments of nail psoriasis have been published in literature as means to standardize the previous subjective assessments of authors. OBJECTIVES: Using Nail Psoriasis Severity Index for evaluation in patients with plaque psoriasis during treatment with acitretin. METHODS: Thirty volunteers with plaque psoriasis were selected for the study. Twenty patients (8 women and 12 men completed the study. The initial dose of acitretin was 0.3 mg/kg/day for 30 days and was later raised to 0.5 mg/kg/day. Nail Psoriasis Severity Index was collected in the first evaluation, after 2 and 4 months. Nails of both hands were evaluated. RESULTS: nail lesions were present in all patients at first evaluation. The initial Nail Psoriasis Severity Index median was 20 and the final score 20.5 (2.5% of worsening at the end of the study. No statistically significant difference between the three evaluations was found (X2 = 0.8084, GL = 2, p = 0.6657. Seven patients worsened in the final score. Three patients improved 50% of the initial Nail Psoriasis Severity Index and only one had an improvement of 75%. Linear correlation showed a weak association between the improvement percentage in PASI and Nail Psoriasis Severity Index (r = 0.105, F = 2.12, p = 0.162. CONCLUSION: The method was easy and of rapid execution while potentially bringing information about changes in nail plate and matrix during treatment. The Nail Psoriasis Severity Index does not quantify the existing lesions and might not have the sensitivity to detect small changes.FUNDAMENTOS: instrumentos de avaliação da psoríase ungueal têm sido publicados na literatura como meio de padronizar as avaliações antigamente subjetivas dos autores. OBJETIVOS: utilizar índice de Gravidade da Psoríase Ungueal ou Nail Psoriasis Severity Index para avaliação em pacientes portadores de psoríase em placas durante o tratamento com acitretina.

    {sup 99m} Tc emits 140 keV of very low gamma-ray radiation energy, as low as conventional diagnostic X-ray, and has short half-life of 6.0058 hours. Therefore, as radioactive tracer, {sup 99m} Tc provides high quality diagnostic images but keeps total patient radiation exposure low. Depending on the tagging pharmaceuticals and procedures, {sup 99m} Tc can be applied for the diagnostics of various target organs and diseases: brain, myocardium, thyroid, lungs, liver, gallbladder, kidneys, skeleton, blood and tumors. More than 95% of {sup 99}Mo is produced through fission of {sup 235}U worldwide because, {sup 99m}o generated from the fission (fission {sup 99}Mo) exhibits very high specific activity (<100 Ci/g). Over 90% of fission {sup 99}Mo producers have been used highly enriched uranium (HEU) targets so far. However, the IAEA recommends the use of low enriched uranium (LEU) to the {sup 99}Mo producers for nonproliferation reason. These days, worldwide {sup 99}Mo supply is not only insufficient but also unstable. Because, most of the main {sup 99}Mo production reactors are about 50 years old and suffered from frequent and unscheduled shutdown. Planned weekly productivity of 2000 Ci fission {sup 99}Mo, in a 6-day reference, will cover 100% domestic demand of Korea, as well as 20% of international market. It is expected to replace 4.3 million USD ($800/Ci) of {sup 99}Mo import for domestic market while exporting 82.8 million USD for world market, annually.

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. Trabalhando em estreita articulação com as associações de pacientes e ex-pacientes, inicialmente como enfermeira e, depois, na implantação das políticas de atenção ao hanseniano, Tadiana Alves Moreira fala sobre a importância do diagnóstico precoce visando evitar seqüelas físicas que a doença provoca quando alcança estágios avançados, e assim, reduzir o estigma que recai sobre os seus portadores.The interviewee speaks about the endemic disease, which at present contaminates 4.4 out of ten thousand inhabitants in Brazil, the country with the second highest number of patients.

    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).

    Day and night side narrow angle images taken on January 1, 2001 illustrating storms visible on the day side which are the sources of visible lightning when viewed on the night side. The images have been enhanced in contrast. Note the two day-side occurrences of high clouds, in the upper and lower parts of the image, are coincident with lightning storms seen on the darkside. The storms occur at 34.5 degrees and 23.5 degrees North latitude, within one degree of the latitudes at which similar lightning features were detected by the Galileo spacecraft. The images were taken at different times. The storms' longitudinal separation changes from one image to the next because the winds carrying them blow at different speeds at the two latitudes.

    Every year in late January, NASA holds a Day of Remembrance, honoring the astronauts lost in three major space flight accidents: Apollo 1, Challenger and Columbia. In an odd tragic coincidence, all three of the accidents happened in late January or early February, although many years apart: Apollo 1 on January 27, 1967; Challenger on January 28, 1986; and Columbia on February 1, 2003. While the day is a solemn one to commemorate the astronauts who lost their lives, it is also a day to reflect on the errors that led to the accidents and to remind all NASA workers and managers to be ever vigilant so that preventable accidents don't happen again.

    Full Text Available FUNDAMENTOS: Psoríase é uma doença inflamatória crônica, sistêmica, mediada por fatores imunológicos. Serão abordados os alimentos que atuam sobre estes fatores, contribuindo para a psoríase. Como doença sistêmica, que compartilha o mesmo substrato fisiopatológico com outras comorbidades, a dieta alimentar também leva à piora das comorbidades. OBJETIVO: Destacar um grupo de alimentos que pode atuar como um fator de manifestação e/ou agravo da psoríase e ao mesmo tempo viabilizar estratégias individuais para alimentos que devam ser introduzidos. MÉTODOS: 43 pacientes foram selecionados, com diversas formas de psoríase (exceto psoríase pustulosa e eritrodérmica, e responderam a um questionário sobre seus hábitos alimentares na primeira consulta, focando a atenção no consumo de café preto, chá preto, chocolate, mate, pimenta, defumados, carne de gado e realçador de sabor (glutamato monossódico. Na sequência, o paciente foi orientado a suspender bebidas com qualquer percentagem alcoólica e o tabagismo.

    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.

    On behalf of the International Women Day, the Sun gave a hot kiss to our mother Earth in a form of a full halo CME generated by the yesterday's double X-class flare. The resulting geomagnetic storm gives a good opportunity to compare the performance of space weather forecast models operating in near-real-time. We compare the forecasts of most major models and identify some common problems. We also present the results of our own near-real-time forecast models.

    Full Text Available Toxocariasis is caused by infection of man by Toxocara canis and Toxocara cati larvae, the common roundworm of dogs and cats. Because larvae are difficult to detect in tissues, diagnosis is mostly based on serology. Non specific reactions are observed mainly due to cross-reactivity with Ascaris sp antigens. This investigation aimed at developing and evaluating an indirect antibody competition ELISA (IACE employing a specific rabbit IgG anti-Toxocara canis excretory-secretory antigens as the competition antibody, in order to improve indirect ELISA specificity performed for toxocariasis diagnosis. For that, the rabbit IgG was previously absorbed by Ascaris suum adult antigens. Sensitivity and specificity of IACE were first evaluated in 28 serum samples of mice experimentally infected with T. canis embryonated eggs. Adopting cut-off value established in this population before infection, sensitivity and specificity were 100% after 20 days post-inoculation. For human population IACE was evaluated using sera from 440 patients with clinical signs of toxocariasis and the cut-off value was established with 60 serum samples from apparently healthy individuals. Using as reference test the indirect ELISA performed by Adolfo Lutz Institute, sensitivity was 60.2%, specificity was 98% and concordance was 77.3%. Repeatability of IACE was evaluated by the inter-reactions variation coefficient (2.4%.A toxocaríase, uma emergente zoonose, é uma síndrome clínica decorrente da infecção humana por larvas de Toxocara canis e Toxocara cati, parasitas intestinais de cães e gatos, respectivamente. A dificuldade de detecção das larvas nos tecidos e a inespecificidade dos sinais clínicos tornam os testes sorológicos os meios diagnósticos mais adequados. Os antígenos excretores-secretores de T. canis empregados nos testes sorológicos, embora tenham contribuído para melhorar a especificidade destes, apresentam reações cruzadas com diversos parasitas

    O sistema intensivo de produção de suínos criados ao ar livre (SISCAL é caracterizado por manter os suínos em piquetes com cobertura vegetal, nas fases de reprodução, maternidade e creche, cercados com tela e/ou fios de arame eletrificado. Este trabalho teve por objetivo relatar aspectos epidemiológicos de um foco de tungíase ocorrido em um SISCAL. Foram examinados clinicamente 72 animais, sendo 6 cachaços, 9 fêmeas lactantes, 13 em gestação e 6 em cobrição, 20 leitões lactantes e 34 leitões desmamados e transferidos para unidades de terminação. Verificou-se que nenhum dos cachaços estava infestado (granja 1= 48 e que em 50% do total de fêmeas examinadas ocorreram lesões com maior freqüência nos tetos, o que nas porcas lactantes deu origem à agalaxia por obstrução do canal galactóforo ocasionando involução da glândula mamária. Em 90% dos leitões lactantes constatou-se dificuldade de locomoção causada pela presença do parasito na região plantar do casco e 25% apresentavam, além disto, lesões no jarrete. Dos leitões desmamados transferidos para unidades de terminação em confinamento, com 40-47 dias (granja 2, n=24 e com 70 dias (granja 3, n= 10 de idade 100% e 80%, respectivamente. ainda apresentavam lesões semelhantes às observadas em leitões lactantes. Conclui-se que a tungíase pode afetar suínos criados ao ar livre podendo causar agalaxia em porcas lactantes e dificuldade de locomoção em leitões lactantes e desmamados.

    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. ...

  20. Seven remarkable days

    CERN Document Server

    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...

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

    The objectives of the International Women's Day are: 1) to celebrate the struggle for women's rights in the economic, social, political, and cultural domain; 2) to reaffirm women's solidarity in the struggle for peace; 3) and to show what women have achieved. In 1988, Uganda's government of the National Resistance Movement created the Ministry of Women in Development. The period 1988-1990 was one of consultations, needs assessment, planning, and recruiting staff for the Ministry. From 1990 to 1993, measurable results have been achieved. The Ministry's gender concerns pertained to the sector policies of the Ministries of Agriculture, Animal Industry and Fisheries, Education, Health, Water, Energy, Minerals, and Environment Protection. Under the Umbrella Project for Women in Development, gender sensitization has been achieved with policy makers in ministries, at district level, and in the media. Gender issues have also been incorporated in the National Political School Curriculum. The Ministry has also trained a corps of 73 women trainers from 38 districts. The Ministry, with funding from DANIDA, collected women's views on the constitution through meetings and seminars in all the districts in the country. Recommendations were submitted in a consolidated report to the Constitution Commission. A pilot para-legal scheme is successfully being implemented in Kamuli district. A community-based pool of legal advisors has been developed. Legal matters that affect both women and men are undertaken at the community level. The economic emancipation of women is a crucial part of the Ministry's mandate. In conjunction with NGOs, pilot credit programs are being run in Mukono, Jinja, Mbale, and Kapchorwa districts. Cross-sectoral programs are in close collaboration with the rural water and sanitation program, the Northern Uganda rehabilitation program, and the integrated Basic Education Pilot Project to be implemented in 8 districts.

This years award went to Giovanni Fazio of the Harvard-Smithsonian Center for Astrophysics. Fazio became a leader in gamma ray astronomy before switching mid-career to the study of infrared astronomy, and he gave his award lecture on the latter subject, specifically on the Spitzer Space Telescope, one of the most successful infrared telescopes of all time.Artists rendering of the Spitzer space telescope. [NASA/JPL-Caltech]Spitzer has been operating for more than twelve years, and has resulted in over six thousand papers in refereed journals in that time. The telescope sits in an Earth-trailing orbit around the Sun, and is now farther from the Earth (1.4 AU) than the Earth is from the Sun. Fazio gave the audience a fascinating overview of the science done by Spitzer over more than a decade. One of the most productive areas of research for Spitzer is the study of exoplanets, which hadnt even been discovered when the Spitzer Telescope was first conceived.

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

    Editors note: This week were in Boulder, Colorado at the 47th meeting of the AAS Solar Physics Division (SPD). Follow along to catch some of the latest news from the field of solar physics!The 2016 SPD meeting was launched this morning from the University of Colorado Boulder campus. 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

  18. Broadband generation by multiple four-wave mixing process due to ASE Q-switching in high-power double-clad ytterbium-doped fiber amplifier

    Science.gov (United States)

    Chowdhury, Sourav D.; Shekhar, Nishant; Saha, Maitreyee; Sen, Ranjan; Pal, Mrinmay

    2014-11-01

    Broadband output from 1060nm to 1700nm and cascaded four-wave mixing generated red light pulsing is observed in a fiber amplifier set up consisting of a 5.5m double clad, double D shaped Ytterbium doped fiber, a single clad passive fiber for excess pump absorption and a splitter, both with and without a CW seed. Self-pulsing occurs from ASE due to passive Q-switching by saturable absorption effect of the active fiber and also depends on splice loss. The pulses generate broadband output by multiple four-wave mixing process with maximum broadening efficiency near 1300nm which is the zero dispersion wavelength for silica fiber. Pulses traveling both in forward and backward direction have enough peak power and energy to damage splice points and fiber components. When seeded the self-pulsing and broadband generation is often suppressed but again generate at increased pump powers.

  19. Wide range operation of regenerative optical parametric wavelength converter using ASE-degraded 43-Gb/s RZ-DPSK signals.

    Gao, Mingyi; Kurumida, Junya; Namiki, Shu

    2011-11-07

    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.

    The authors describe a detailed Monte Carlo (MC) method for the coupled transport of ionizing particles and charge carriers in amorphous selenium (a-Se) semiconductor x-ray detectors, and model the effect of statistical variations on the detected signal. A detailed transport code was developed for modeling the signal formation process in semiconductor x-ray detectors. The charge transport routines include three-dimensional spatial and temporal models of electron-hole pair transport taking into account recombination and trapping. Many electron-hole pairs are created simultaneously in bursts from energy deposition events. Carrier transport processes include drift due to external field and Coulombic interactions, and diffusion due to Brownian motion. Pulse-height spectra (PHS) have been simulated with different transport conditions for a range of monoenergetic incident x-ray energies and mammography radiation beam qualities. Two methods for calculating Swank factors from simulated PHS are shown, one using the entire PHS distribution, and the other using the photopeak. The latter ignores contributions from Compton scattering and K-fluorescence. Comparisons differ by approximately 2% between experimental measurements and simulations. The a-Se x-ray detector PHS responses simulated in this work include three-dimensional spatial and temporal transport of electron-hole pairs. These PHS were used to calculate the Swank factor and compare it with experimental measurements. The Swank factor was shown to be a function of x-ray energy and applied electric field. Trapping and recombination models are all shown to affect the Swank factor.

    Traditionally, samples are collected on-site (i.e., in the field) and are shipped to a lab for chemical analysis. An alternative is offered by using portable chemical analysis instruments that can be used on-site (i.e., in the field). Many analytical measurements by optical emission spectrometry require use of light-sources and of spectral lines that are in the Ultra-Violet (UV, ~200 nm - 400 nm wavelength) region of the spectrum. For such measurements, a portable, battery-operated, fiber-optic spectrometer equipped with an un-cooled, linear, solid-state detector may be used. To take full advantage of the advanced measurement capabilities offered by state-of-the-art solid-state detectors, cooling of the detector is required. But cooling and other thermal management hamper portability and use on-site because they add size and weight and they increase electrical power requirements. To address these considerations, an alternative was implemented, as described here. Specifically, a microfabricated solid-state detector for measurement of UV photons will be described. Unlike solid-state detectors developed on crystalline Silicon, this miniaturized and low-cost detector utilizes amorphous Selenium (a-Se) as its photosensitive material. Due to its low dark current, this detector does not require cooling, thus it is better suited for portable use and for chemical measurements on-site. In this paper, a microplasma will be used as a light-source of UV photons for the a-Se detector. For example, spectra acquired using a microplasma as a light-source will be compared with those obtained with a portable, fiber-optic spectrometer equipped with a Si-based 2080-element detector. And, analytical performance obtained by introducing ng-amounts of analytes into the microplasma will be described.

    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. 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. 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. 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

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.

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

    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

    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.

    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.

    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 A sorologia utilizando o antígeno espécie-específico do Mycobacterium leprae, PGL-I, pode ser um marcador de carga bacteriana em pacientes com hanseníase. Estudos identificaram potencial de uso da sorologia na classificação de pacientes para fins de tratamento, monitoramento de terapia, risco de recidiva e na seleção dos contatos com maior risco de adoecer. Foi realizada uma revisão sistemática e 26 artigos foram incluídos na análise comparativa. Avaliamos os resultados do uso da sorologia PGL-I em diferentes situações, suas limitações e possíveis aplicações. Estudos mostraram eficácia da sorologia PGL-I na classificação de pacientes, monitoramento da terapia, e nas reações hansênicas como teste preditivo. Para diagnóstico precoce e seguimento de população de alto risco, as metodologias utilizadas ainda não demonstraram custo-benefício favorável, porém estudos indicam que a utilização do teste poderá influenciar positivamente nos programas de controle da hanseníase. Com técnicas simples e robustas, o uso da sorologia PGL-I é viável.Serology using a species-specific antigen for Mycobacterium leprae, PGL-I, could be a marker for the bacterial load of patients with leprosy.

    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.

    Although amorphous selenium (a-Se) has a long and successful history of application in optical and X-ray imaging, some of its fundamental properties are still puzzling. In particularly, the mechanism of carrier recombination following x-ray excitation and electric field and temperature dependences of the electron-hole pair creation energy (W_e_h_p) remain unclear. Using the combination of X-ray photocurrent and pulse height spectroscopy measurements, we measure W_e_h_p in a wide range of temperatures (218–320 K) and electric fields (10–100 V/µm) and show that the conventional columnar recombination model which assumes Langevin recombination within a column (a primary electron track) fails to explain experimental results in a wide range of electric fields and temperatures. The reason for the failure of the conventional model is revealed in this work, and the theory of the columnar recombination is modified to include the saturation of the recombination rate at high electric field in order to account for the experimental results in the entire range of fields and temperatures.

    1980-02-01

    Potential advantages of day stay surgery are cost saving, improved utilization of staff and hospital facilities, and reduction of stress for the paediatric patient and his family. The successful program requires careful case selection, full operating and anesthetic facilities and good follow-up. Day stay surgery was initiated at Royal Alexandra Hospital for Children in 1974. Experience is reviewed in relation to the total number and nature of surgical admissions and the daily utilisation of the facility. Utilization has markedly increased in the past 2 yr. Current practice is reviewed with regard to initial assessment, preparation for surgery and overall management during the day admission. Parental attitudes towards day stay surgery were evaluated indicating both the advantages and the problems encountered. These related mainly to insufficient information, transport difficulties and afternoon operations. Recommendations for improving the day stay service are discussed with special reference to: (1) communication with the parents as to adequate pre-operative explanation, revision of the day stay information pamphlet and improved distribution, and clear postoperative instructions, (2) the timing of operations, and (3) transport and parking facilities.

    Full Text Available FUNDAMENTOS: A psoríase leva a um impacto negativo significativo na qualidade de vida e está associada a comorbidades. A atividade inflamatória das placas psoríacas se inicia, em parte, pela ativação de linfócitos Th1, que liberam citocinas pró-inflamatórias, como TNF alfa. Infliximabe neutraliza a atividade biológica do TNF alfa. Reações adversas que ocorrem durante a infusão e até 24 horas após são chamadas de agudas. Reações tardias ocorrem entre 24 horas e 14 dias após infusão. OBJETIVO: Avaliar o perfil dos pacientes com psoríase moderada a grave e resistente ao tratamento convencional, bem como as reações adversas ao infliximabe. MÉTODO: Foram tratados com infliximabe 53 pacientes: 40 homens e 13 mulheres. A dose utilizada foi 5 mg/kg nas semanas 0, 2 e 6 (fase de indução, seguida da fase de manutenção a cada oito semanas. RESULTADO: Dentre os 53 pacientes, seis se submeteram apenas à fase de indução, obtiveram Pasi 90-100 e não receberam mais a droga. Quarenta e sete pacientes continuaram recebendo a medicação por pelo menos dois, três anos. Deles, 55,3% (26 apresentaram algum efeito adverso. Os efeitos adversos precoces foram observados em 34% dos pacientes, e os tardios, em 36,1% dos pacientes. Foi encontrada uma prevalência de 57,4% de comorbidades nesses pacientes. CONCLUSÃO: O infliximabe mostrou-se seguro e eficaz no presente estudo. Dentre as comorbidades associadas aos pacientes neste estudo, a obesidade se relacionou com uma resposta mais tardia e menos eficiente. Efeitos adversos precoces e tardios, quando bem monitorados, não impedem a manutenção da terapêutica e não expõem os pacientes a riscos não controlados.BACKGROUND: Psoriasis exerts a significant negative effect on quality of life and is associated with comorbidities.

    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

    Radioimmunoassay methods have been developed for plasma T, DHT, A and DHEA. Plasma volumes usually employed were: 0,2 ml and 0,5 ml for men and women, respectively for T: 1,0 ml from DHT and 0,5 ml to A and DHEA. After preliminary extraction with diethyl ether, the extracts were applied to Sephadex LH-20 microcolumns to separate T from DHT and to Al 2 O 3 microcolumns purification of DHEA. Following elution, the dried, purified extracts were incubated with specific antisera at temperature 4 0 C overnight, the separation of antibody bound and free fractions being done on activated charcoal-dextrana T-70. The counting was done in liquid scintillations. Specificity studies have shown that the assays for all steroids were specific. The sensitivity was 5 pg for A and DHEA, 6 pg for T and DHT. The interassay coeficient of variation was 5-10% and the interessay precision was 10-15%. The accuracy was satisfactory with a - 8,74% for DHT, 104,82 +- 9,41% for A and 103,66 +- 5,71% for DHEA. The mean +- SD of plasma T, DHT, A and DHEA concentrations in normal men and women determined by these methods were as folows: in men, T:5,2 ng/ml +- 1,3, DHT:0,26 +- 0,18, A:0,9 +- 0,4 and DHEA:4,6 +- 17 and in females: T:0,5 ng/ml +- 0,2, DHT:0,4 +- 0,2, A:0,8 +- 0,5 and DHEA:4,8 +- 1,7. The methodology applied for blood collected simultaneously from peripheral and left and right adrenal vein effluents in basal conditions, after dexamethasone suppression and ACTH stimulation clearly demonstrated direct secretion (presence of a steroid gradient Peripheral/Adrenal vein) of the androgens studied in congenital defficiency of cortical 21-OH'ase.

    Full Text Available A 22 year-old horse developed cholelithiasis with marked atrophy of the right lateral hepatic lobe. The horse had a history of intermittent colic since three years of age, and one of the first episodes of colic was associated with icterus. The size of the right lateral hepatic lobe was extremely reduced. There was a large choledocholith in the common hepatic duct, and several hepatoliths and choleliths in the intra- and extra-hepatic billiary ducts. Microscopically, there was severe atrophy of the right lobe with diffuse proliferation of connective tissue and billiary ducts. The left lateral lobe had peri-portal fibrosis with proliferation of billiary ducts, and billiary stasis. Chemical analysis of the calculi detected amorphous and triple phosphate, bilirubin, calcium, and iron.Um cavalo de 22 anos de idade desenvolveu quadro de colelitíase severa com atrofia do lobo lateral direito. O animal tinha histórico de cólica recorrente, desde os três anos de idade, sendo que um dos primeiros episódios de cólica foi acompanhado de icterícia. O lobo hepático lateral direito estava extremamente diminuído de volume. Havia um grande coledocólito localizado no ducto hepático comum e inúmeros hepatólitos e colélitos nos ductos biliares intra e extra-hepáticos. Microscopicamente, foi observada atrofia acentuada do lobo direito, com proliferação difusa de tecido conjuntivo fibroso e de ductos biliares. O lobo lateral esquerdo apresentava fibrose periportal difusa associada à proliferação acentuada de ductos biliares e estase biliar. Análise química das concreções detectou fosfato triplo e amorfo, bilirrubina, cálcio e ferro.

    This year, the Children’s Day-Care Centre (EVE) and School works on the theme of colours. Every class has their own project revolving around this common theme. The class of Claire, Sandrine and Nadia, introduced a monthly “Colour Day”. The objective of this day is to offer children different activities (arts and crafts, baking, etc.) designed around a specific colour. The children get a chance to decorate their classroom and learn in many different ways inspired by the colours blue, red, and many others. The parents are also called to contribute and invited to dress their children in the colour of the day. In September, we discovered the colour blue, in October it was time for red, and in mid-November yellow will brighten up our structure. Everyone plays along, making this a very festive day for us all. On Tuesday, 20 September, we saw the whole School turn blue! We were all dressed in blue and we made blue paintings, too!

    Full Text Available Although not considered as an endemic region, the Northeast of Brazil has the necessary conditions for the development of taeniasis-cysticercosis complex. In a previous paper, we demonstrated that Mulungu do Morro municipality, in the State of Bahia, has a high seroprevalence to cysticercosis in epileptic patients. OBJECTIVE: to determine the prevalence of taeniasis and positive cysticercosis serology in the population of Mulungu do Morro. METHOD: blood and stool samples were collected from a random sampling of the population, by family. The identification of antibodies against T. solium cysticerci was made by EITB and T. solium antigens were identified using a polyclonal antibody-capture ELISA. RESULTS: the cysticercosis seroprevalence was 1.6% (C.I. = 0.8 to 2.8% and the taeniasis prevalence 4.5% (C.I. = 3.0 to 6.5%. Seropositivity to cysticercosis was higher among those who lived in a house of a person testing positive for coproantigen, p=0.017. CONCLUSION: our results demonstrate that the taeniasis-cysticercosis complex is endemic in Mulungu do Morro. We believe that all areas in the world with the same socio-economic and sanitary characteristics are likely to have high prevalence of this parasite.Embora alguns autores não a considerem uma região endêmica, existem no Nordeste do Brasil as condições necessárias para o desenvolvimento do complexo teníase/ cisticercose.

    An analytical method associating accelerated solvent extraction (ASE) and solid-phase micro-extraction (SPME) in immersion mode combined with gas chromatography dual electrons capture detectors (SPME-GC-2ECD) has been developed and studied for the simultaneous determination of 19 organochlorine pesticides (OCPs) and 22 polychlorinated biphenyls (PCBs) in air samples (active and XAD-2 passive samplers). Samples were extracted with ASE with acetonitrile using the following conditions: temperature, 150 °C; pressure, 1500 psi; static, 15 min; cycles, 3; purge, 300 s; flush, 100 %. Extracts were reduced to 1 mL, and 500 μL of this extract, filled with deionised water, was subject to SPME extraction. Experimental results indicated that the proposed method attained the best extraction efficiency under the optimised conditions: extraction of PCB-OCP mixture using 100-μm PDMS fibre at 80 °C for 40 min with no addition of salt. The performance of the proposed ASE-SPME-GC-2ECD methodology with respect to linearity, limit of quantification and detection was evaluated by spiking of XAD-2 resin with target compounds. The regression coefficient (R (2)) of most compounds was found to be high of 0.99. limits of detection (LODs) are between 0.02 and 4.90 ng m(-3), and limits of quantification (LOQs) are between 0.05 and 9.12 ng m(-3) and between 0.2 and 49 ng/sampler and 0.52 and 91 ng/sampler, respectively, for XAD-2 passive samplers. Finally, a developed procedure was applied to determine selected PCBs and OCPs in the atmosphere.

Essa complicação pode ocorrer em mais de 50% da população adulta com doença falciforme. A colecistectomia é a conduta consensual para pacientes sintomáticos, mas nos assintomáticos a sua indicação é controversa. OBJETIVOS: Verificar a prevalência de colelitíase em pacientes com doença falciforme e descrever a conduta tomada em caso de diagnóstico da complicação, numa corte de pacientes seguidos num centro terciário de hematologia pediátrica. MÉTODOS: Neste estudo descritivo e retrospectivo, foram revistos prontuários de 225 pacientes e os dados relacionados à evolução clínica desses indivíduos foram registrados. RESULTADOS: A freqüência cumulativa de colelitíase foi de 45%, sendo que metade deles não apresentava quaisquer sintomas. As médias de idade ao diagnóstico de colelitíase e seu tratamento cirúrgico foram, respectivamente, 12,5 anos (desvio padrão = 5 anos e 14 anos (desvio padrão = 5,4 anos.

    Landfills reaching capacity, beaches fouled with trash, neighborhood residents protesting waste disposal sites in their backyards, and municipalities forced to recycle. Sound familiar? These issues might have been taken from today`s headlines, but they were also problems facing mechanical engineers a century ago. Conditions such as these were what led engineers to design the first incinerators for reducing the volume of municipal garbage, as well as for producing heat and electricity. The paper discusses these early days.

    2014-03-01

    In France, the delayed development of day surgery compared to other countries led the ANAP and the HAS in 2011 to enter into a joint work program to provide some reference guide for hospitals to change their practices to outpatient. In this context, organizational guidelines and operational tools were published in May 2013. The method of construction of the recommendations resulting from an original work that combined a three-fold approach: field vision by identifying the highlights of 15 hospitals selected for their representative performance and analyzing the risks of five voluntary hospitals, mobilization organizational theories from the social sciences, using 53 professional experts. The work concluded on 16 organizational recommendations under four forms (basic principles, strategic elements, operational elements and perspectives). These recommendations are accompanied by tools and guides diagnosis and implementation, as well as productions for further reflection. These organizational recommendations confirmed the specificity of day surgery, which is not related to the act, but to the organization, management and optimization of different flows of a hospital (patient flow, professional flows, logistical, informational…). The performance of a day surgery organization is linked to its ability to control its flow and anticipation. Copyright © 2013 Elsevier Masson SAS. All rights reserved.

    Full Text Available A hanseníase é uma doença que tem altos níveis de incidência no Brasil. De origem bacteriana crônica, com alta infectividade e baixa patogenicidade, tem como hospedeiro primário o homem e como agente etiológico o Mycobacterium leprae. O bacilo de Hansen, como também é conhecido o agente, se acumula principalmente na pele, nos nervos periféricos e pares cranianos, levando a diversas lesões cutâneas, também à perda da condução neural e, consequentemente, a severas alterações anatômicas e funcionais nas extremidades do corpo, como membros e região orofacial. De acordo com estas premissas, foi realizada uma revisão da literatura com intuito de mostrar a fisiopatologia da doença e sua classificação de acordo com as suas manifestações. Desta forma, a literatura, por intermédio de alguns estudos, mostrou que esta doença pode provocar alterações que comprometem significativamente a voz, a audição, os órgãos fonoarticulatórios e as funções estomatognáticas, tornando-se assim, de grande relevância à Fonoaudiologia.Hansen's disease is a malady that has high incidence levels in Brazil. It has a chronic bacterial origin, with high infectivity and low pathogenicity, having the man as its primary host, and the Mycobacterium leprae as its etiological agent. The Hansen's bacillus, as it is known, accumulates mainly in the skin, the peripheral nerves and the cranial nerves pairs, causing many skin lesions, as well as loss of neural conduction and, consequently, severe anatomical and functional changes in the ends of the body, such as members and the orofacial region. Based on these premisses, it was carried out a literature review in order to show the pathophysiology of the disease and its classification according to its manifestations. The literature review showed, through some studies, that the disease might cause alterations that significantly compromise the voice, the hearing, the phonoarticulatory organs, and the

    Full Text Available A terapia expulsiva medicamentosa na litíase ureteral tem ganhado importante espaço na prática clínica, visto que é um método não invasivo e de grande eficácia. Como se trata de uma afecção comum, de alta incidência e custo, a terapia expulsiva possibilita um manejo clínico menos dispendioso e invasivo, quando comparada a procedimentos intervencionistas. Há consenso na literatura que a terapia expulsiva medicamentosa é efetiva e deve ser utilizada em cálculos com cerca de 5 milímetros de diâmetro, visto que as drogas utilizadas aumentam a taxa e diminuem o tempo de expulsão, além de diminuir a dor e o número de internações. O tamanho e localização do cálculo são de extrema relevância para que se possa considerar o manejo conservador. As drogas que obtém as melhores taxas expulsivas são os bloqueadores dos receptores alfa-adrenérgicos e os bloqueadores dos canais de cálcio. Analgésicos também são utilizados para o alívio da dor e o uso de corticoides ainda é questionado. Medicamental expulsive therapy for ureteral stones has gained important place in clinical practice, because it is a noninvasive and highly effective method. As it is a common disorder with high incidence and cost, expulsive therapy provides a less costly and invasive clinical management when compared to interventional procedures. There is a consensus that the medicamental expulsive therapy is effective and should be used in calculations with about 5 millimeters in diameter, since the drugs used increase rate and decrease the time of expulsion, in addition to reducing the pain and the number of hospitalizations. The size and location of the calculi are very important for it to be considered conservative management. The drugs that get the best expulsive rates are alpha - adrenergic receptor blockers and calcium channel blockers. Analgesics are also used for pain relief and the use of corticosteroids is still questioned.

    Purpose: The authors describe the modification to a previously developed Monte Carlo model of semiconductor direct x-ray detector required for studying the effect of burst and recombination algorithms on detector performance. This work provides insight into the effect of different charge generation models for a-Se detectors on Swank noise and recombination fraction. Methods: The proposed burst and recombination models are implemented in the Monte Carlo simulation package, ARTEMIS, developed byFang et al. [“Spatiotemporal Monte Carlo transport methods in x-ray semiconductor detectors: Application to pulse-height spectroscopy in a-Se,” Med. Phys. 39(1), 308–319 (2012)]. The burst model generates a cloud of electron-hole pairs based on electron velocity, energy deposition, and material parameters distributed within a spherical uniform volume (SUV) or on a spherical surface area (SSA). A simple first-hit (FH) and a more detailed but computationally expensive nearest-neighbor (NN) recombination algorithms are also described and compared. Results: Simulated recombination fractions for a single electron-hole pair show good agreement with Onsager model for a wide range of electric field, thermalization distance, and temperature. The recombination fraction and Swank noise exhibit a dependence on the burst model for generation of many electron-hole pairs from a single x ray. The Swank noise decreased for the SSA compared to the SUV model at 4 V/μm, while the recombination fraction decreased for SSA compared to the SUV model at 30 V/μm. The NN and FH recombination results were comparable. Conclusions: Results obtained with the ARTEMIS Monte Carlo transport model incorporating drift and diffusion are validated with the Onsager model for a single electron-hole pair as a function of electric field, thermalization distance, and temperature. For x-ray interactions, the authors demonstrate that the choice of burst model can affect the simulation results for the generation

    Full text: Cancer can strike anyone at anytime, young or old, rich or poor. It knows no borders. World Cancer Day, on 4 February, was initiated to raise global awareness of cancer issues and stimulate new strategies and thinking to combat the killer disease. Nowhere is the need greater than in the developing world, where millions of people are suffering and dying due to lack of cancer prevention and treatment. According to the World Health Organisation (WHO), 84 million people will die of cancer in the next 10 years, more than 70% of them in low-income countries, unless action is taken now. The IAEA's Programme of Action for Cancer Therapy (PACT) was created to help poorer countries confront the growing cancer crisis by integrating radiotherapy into comprehensive cancer control programmes. As it celebrates its third birthday on World Cancer Day, PACT can claim significant progress in building effective relationships with a broad array of stakeholders, initiating six pilot projects and gaining increasing support from Member States. The IAEA commends all organizations, agencies and individuals engaged in the battle to defeat this dreadful disease. We look forward to continued collaboration with international partners to help bring hope to cancer patients, to relieve their suffering and to save lives. (IAEA)

A amostra constou de 93 membros da rede social, com idade entre 20 e 70 anos, que apoiaram o curso de ação de 83 pacientes diagnosticados no período do estudo. A análise buscou detectar variáveis capazes de discriminar os membros da rede de apoio dos pacientes de hanseníase classificados como casos (presença de incapacidades ou lesões precursoras de incapacidades ou controles. O estudo evidenciou a escassez de informações sobre a transmissão da hanseníase e revelou um quadro transicional onde se confrontam expectativa de cura e uma visão estigmatizante das conseqüências da doença. Apenas uma quarta parte dos sujeitos do estudo suspeitou, antes do diagnóstico, que o paciente era portador de hanseníase, o que sugere baixa percepção do risco representado pela doença e reforça a concepção da invisibilidade das suas manifestações corporais. Os resultados mostram um perfil de percepção e manejo da hanseníase que pode facilitar a propagação da doença e a instalação ou agravamento das suas conseqüências físicas e sociais.This article describes a study done in Recife, Brazil, between November 1993 and July 1994 to explore the opinions of the members of the social network (for example, family members, friends, and neighbors of carriers of Hansen's disease regarding their estimation, interpretation, and management of physical manifestations of the disease in the time leading up to diagnosis.

    Full Text Available In poor countries, the burgeoning middle-class population, people who eat three times a day1, is placing profound worldwide price pressure on food and natural resources. This keynote address examines the implications of the boom in middle-class population on the world economy and innovation. Where not long ago food production was aplenty and the problem was distribution, today growing middle-class demand on food production has prices of food staples such as wheat and corn, and their derivatives, inflating. This follows the trend in the growth of prices of natural resources and durable commodities emanating from economic globalization and the building of infrastructure. This keynote address examines the five prices that are in play in the global economy and a brief perspective through the supply chain window. The address also examines implications of the middle-class boom and the additional importance this places on innovation, particularly in three areas of economic structure.

    2009-01-01

    At lunch time on Wednesday 21 January a guest at the CERN hostel put her food in the microwave oven and switched it on. "Within seconds I smelt plastic. I looked into the oven and saw flames. I switched it off, took my food out. But the flames continued and so I ran for the door." In the corridor she ran into Jane Kiranga, a cleaning lady working for the company ISS. Without hesitation Jane picked up a portable fire extinguisher, returned to the kitchen and stopped the fire. The Fire Brigade arrived a few minutes later and only needed to ventilate the kitchen. "Jane was just in time, because the flames had not left the oven yet. Her model behaviour deserves recognition," said the team leader on duty for the CERN Fire Brigade. A few days later Jane received a gift voucher from the Prevention and Training section of the Safety Commission (photo).

  4. Channel by Day and Night

    Science.gov (United States)

    2004-01-01

    [figure removed for brevity, see original site] Released 17 June 2004 This pair of images shows part of a small channel. Day/Night Infrared Pairs The image pairs presented focus on a single surface feature as seen in both the daytime and nighttime by the infrared THEMIS camera. The nighttime image (right) has been rotated 180 degrees to place north at the top. Infrared image interpretation Daytime: Infrared images taken during the daytime exhibit both the morphological and thermophysical properties of the surface of Mars. Morphologic details are visible due to the effect of sun-facing slopes receiving more energy than antisun-facing slopes. This creates a warm (bright) slope and cool (dark) slope appearance that mimics the light and shadows of a visible wavelength image. Thermophysical properties are seen in that dust heats up more quickly than rocks. Thus dusty areas are bright and rocky areas are dark. Nighttime: Infrared images taken during the nighttime exhibit only the thermophysical properties of the surface of Mars. The effect of sun-facing versus non-sun-facing energy dissipates quickly at night. Thermophysical effects dominate as different surfaces cool at different rates through the nighttime hours. Rocks cool slowly, and are therefore relatively bright at night (remember that rocks are dark during the day). Dust and other fine grained materials cool very quickly and are dark in nighttime infrared images. Image information: IR instrument. Latitude 19.8, Longitude 141.5 East (218.5 West). 100 meter/pixel resolution. Note: this THEMIS visual image has not been radiometrically nor geometrically calibrated for this preliminary release. An empirical correction has been performed to remove instrumental effects. A linear shift has been applied in the cross-track and down-track direction to approximate spacecraft and planetary motion. Fully calibrated and geometrically projected images will be released through the Planetary Data System in accordance with Project

    [figure removed for brevity, see original site] Released 16 June 2004 This pair of images shows part of Lomonosov Crater. Day/Night Infrared Pairs The image pairs presented focus on a single surface feature as seen in both the daytime and nighttime by the infrared THEMIS camera. The nighttime image (right) has been rotated 180 degrees to place north at the top. Infrared image interpretation Daytime: Infrared images taken during the daytime exhibit both the morphological and thermophysical properties of the surface of Mars. Morphologic details are visible due to the effect of sun-facing slopes receiving more energy than antisun-facing slopes. This creates a warm (bright) slope and cool (dark) slope appearance that mimics the light and shadows of a visible wavelength image. Thermophysical properties are seen in that dust heats up more quickly than rocks. Thus dusty areas are bright and rocky areas are dark. Nighttime: Infrared images taken during the nighttime exhibit only the thermophysical properties of the surface of Mars. The effect of sun-facing versus non-sun-facing energy dissipates quickly at night. Thermophysical effects dominate as different surfaces cool at different rates through the nighttime hours. Rocks cool slowly, and are therefore relatively bright at night (remember that rocks are dark during the day). Dust and other fine grained materials cool very quickly and are dark in nighttime infrared images. Image information: IR instrument. Latitude 64.9, Longitude 350.7 East (9.3 West). 100 meter/pixel resolution. Note: this THEMIS visual image has not been radiometrically nor geometrically calibrated for this preliminary release. An empirical correction has been performed to remove instrumental effects. A linear shift has been applied in the cross-track and down-track direction to approximate spacecraft and planetary motion. Fully calibrated and geometrically projected images will be released through the Planetary Data System in accordance with Project

    Following the important progress made in 2016 in the Machine Development (MD) activities that took place in all the accelerators of the LHC injector chain, the days 23-24 March, 2017, have been devoted to summarise the main out- come from the MDs and lay out the plans for the next steps. The event was also triggered by the following motivations and goals: Give a chance to the MD users to present their results; Provide a platform in which MD users, MD coordinators and operations crews meet and discuss openly the optimisation of the MD time and procedures, taking into account of the different perspectives; Provide an overview of all the ongoing activities to better frame their impact in the broader picture of the CERN short and long term projects; Identify the open questions, define and prioritise ma- chine studies in the injectors for 2017; Create the opportunity to obtain and document written reports from MD users. Within this contribution, we just summarise the context and the main points discussed at the ev...

  7. OBESITY : A MODERN DAY PLAGUE.

    2002-01-01

    Obesity is the presence of excess body fat. Unfortunately obesity is taken as a mere cosmetic problem and not a medical one. Today obesity is being 'dealt' with more by the self-proclaimed fitness experts running the rapidly mushrooming fitness centres rather than by medical professionals. But rather than merely a cosmetic problem, obesity should be viewed as a disease because there are multiple biologic hazards at surprisingly low levels of excess fat With the rapid pace of industrialisation and economic progress, today more and more jobs are becoming sedentary and dietary patterns are also changing with a decline in the cereal intake and increase in the intake of sugar and fats. However, inherited physiologic differences in response to eating and exercise are also important factors. Treating obesity can often be a frustrating experience for both the physician and the patient because of the great difficulty in maintaining weight loss over the long term. However, a clear understanding of the causes of obesity and a treatment strategy based on a combination of diet, nutrition, education, exercise, behaviour modification and social support can go a long way in containing this 'modern day plague' before it acquires epidemic proportions.

  8. An Open Day at CERN

    Burckhart, H; Schmid, P; Schuh, S

    Celebrating its 50 years of existence, its achievements and to communicate its plans for the future, CERN is organizing an "Open Day" on Saturday 16 October 2004. This will be a major event for CERN's public relations; some 10000 visitors from near and far are expected to follow CERN's invitation. ATLAS has to, and will, play its role on this occasion. A small group of people (H. Burckhart, C. Potter, P. Schmid and S. Schuh) from the CERN ATLAS Team is acting as interface to CERN's organizing committee. This is all done in close collaboration with the ATLAS Outreach Coordinators. According to our present plans ATLAS will organize three visit sites: - The ATLAS "headquarters" will be in the future ATLAS control room at the pit. We shall show films (ATLAS specific and general HEP), distribute information material, sell our scarves, ties, T-shirts and watches, explain ATLAS in as many languages as we can and - most likely the major attraction - give the visitors the possibility to go down into the cavern. - ...

  9. Higgs discovered at Open Days

    CERN Multimedia

    2008-01-01

    Like his eponymous particle, Peter Higgs can be elusive. However, for the momentous occasion of the Open Days there was a chance, if you were lucky, to catch a glimpse of him. Peter Higgs marvels at the enormity of the ATLAS experiment. Taking a closer look at CMS.Visiting CERN for the first time in more than 20 years, Peter Higgs has become something of a celebrity in the world of particle physics. During his visit he showed genuine amazement at the sight of the LHC and its experiments. On seeing CMS he said, "It’s very impressive, very dramatic. I’d seen pictures of course, but they can’t compare." Surrounded for most of his stay by an entourage of physicists, the notoriously modest scientist laughs at the almost mythical quality his boson has taken on. For him though, it is just one of many aspects of physics that the CMS and ATLAS experiments can shine a light on. Besides finding ...

  10. A red-letter day !

    CERN Multimedia

    2008-01-01

    Today is a red-letter day for the LHC and CERN as a beam of protons has travelled around the LHC ring for the very first time! The start of LHC operation marks the end of a long period in which you have given your all, and this first particle beam circulating in the accelerator now paves the way for discoveries that will open up a whole new field of knowledge. The history of the LHC began in 1984 with a debate on the possible objectives of a future accelerator, based on the state of our knowledge at that time. The CERN Council then approved the single-stage construction of the LHC in 1996, giving the go-ahead for the work that has now reached completion. For the past twelve years, physicists, engineers and technicians from CERN and its associated institutes have been engaged in constructing the three pillars of the LHC: the accelerator (including the upgrade of the existing accelerator chain), the four experiments, and the computing ...

  11. STS-88 Day 10 Highlights

    1998-01-01

    On this tenth day of the STS-88 mission, the flight crew, Commander Robert D. Cabana, Pilot Frederick W. Sturckow, and Mission Specialists Nancy J. Currie, James H. Newman, Jerry L. Ross, and Sergei Krikalev are awakened by the sounds of Elvis Presley's "Hound Dog". Today's activities are devoted mostly to tasks that ready the station for future assembly work. The crew's first job is to release some cable ties on four cables connected on an earlier space walk, three located on Unity's upper mating adapter and one on its lower adapter, to relieve tension on the lines. The space walkers also will check an insulation cover on one cable connection on the lower Pressurized Mating Adapter (PMA 2) to make sure it is fully installed. Near the end of the space walk, the astronauts conduct a detailed photographic survey of the space station from top to bottom. Finally, each astronaut test fires the Simplified Aid for Extravehicular Activity Rescue (SAFER) jet backpacks they are wearing, a type of space "lifejacket," that would allow an astronaut to fly back to the station if they should ever become untethered.

    1995-01-01

    On this eighth day of the STS-84 mission, the flight crew, Cmdr. Charles J. Precourt, Pilot Eileen M. Collins, Payload Cmdr, Jean-Francois Clervoy (ESA), Mission Specialists Edward T. Lu, Carlos I. Noriega, Elena V. Kondakova, Jerry M. Linenger (download), and C. Michael Foale (upload) sing 'The Cosmonauts' Song' to Mir-23 crew members Vasily Tsibliev, Alexander Lazutkin and astronaut Mike Foale, who is beginning his four-month research mission on Mir. Foale and his new crewmates played music as Atlantis departed following the joint phase of the flight. Atlantis' undocking from Mir was modified from previous joint missions in that a flyaround of the station for photographic purposes was not conducted. Instead, Pilot Eileen Collins guided Atlantis below the Mir after the two spacecraft completed their physical separation, stopping three times at distances of 90, 300 and 1,500 feet to collect data from a European sensor device designed to assist future rendezvous of a proposed European Space Agency resupply vehicle with the International Space Station. Once the data collection was completed, the shuttle took advantage of natural orbital mechanics to drift beneath and out in front of Mir.

    On this eleventh day of the STS-78 mission, the flight crew, Cmdr. Terence T. Henricks, Pilot Kevin R. Kregel, Payload Cmdr. Susan J. Helms, Mission Specialists Richard M. Linnehan, Charles E. Brady, Jr., and Payload Specialists Jean-Jacques Favier, Ph.D. and Robert B. Thirsk, M.D., are shown conducting a news conference to discuss the progress of the international mission with media from the United States, Canada and Europe. During the press conference, the crew explained the relevance of the experiments conducted aboard the Life Sciences and Microgravity mission, and praised support crews and researchers on Earth who are involved in the mission. Payload Specialist Dr. Robert Thirsk told Canadian journalists of how the research will not only benefit astronauts as they conduct long-term space missions, but also people on Earth. Some of the research will aid studies on osteoporosis and the effects steroids have on bones, and also may help doctors on Earth develop treatments for muscle diseases like muscular dystrophy, Thirsk told reporters in Toronto.

    Science.gov (United States)

    1998-08-01

    This article describes Japan's celebration of World Population Day, and provides excerpts from speeches at the symposium held on July 8, 1998. The symposium, in Tokyo, was attended by about 300 people. The Chairman of JOICFP gave the opening address. The executive director of UNFPA congratulated Japan for its efforts in the field of population awareness and noted Japan's self-sufficiency despite its importation of 40% of its food and most of its raw materials. A keynote address was delivered by the president of CPE and the former UN Secretary General, who stressed income inequities in the 66% of developing countries within the 185 UN member states. The UN has been promoting sustainable development, but is facing the issue of limited arable land and population growth. The Tutsi and Hutus are fighting due to population based issues. The emphasis should be on women's reproductive rights and protection of women's human rights. 1998 is the 50th year of human rights; progress has been made. The UNFPA Goodwill Ambassador spoke about the disparity between the rich and poor in the Philippines. A small donation reaps incredible progress. Manila has high levels of adolescent childbearing. Men appear to be unaware of the disadvantages of childbearing too early. Rural areas are dominated by strict Roman Catholic beliefs. Manila has commercial sex workers who provide services to Japanese men. The 1998 Kato Award was given to women who raised awareness about coercion in the sex trade and female genital mutilation. The economic situation in Japan creates even greater need to promote family planning and reproductive health.

  16. 100 days in the jungle

    Energy Technology Data Exchange (ETDEWEB)

    Ohler, S.; Hall, V.

    2000-07-01

    This book describes the ordeals of 8 oilfield workers, 7 Canadian and 1 American, who were kidnapped in the jungles of Ecuador on September 11, 1999 while on a job to repair a rusted, leaking pipeline. AEC, the largest Canadian player in the country and the owner of the pipeline, contracted United Pipeline Systems to bring its stake of the pipeline up to Canadian standards. The pipeline ran along a gravel highway in the middle of Ecuador's Oriente region between the oil towns of Lago Agrio and Tarapoa where it met a main pipeline that runs all the way to the Pacific seaport of Esmerelda. Before the petroleum industry moved into Ecuador, the region was untouched rain forest. AEC was drawn to Ecuador by its rich crude reserves and the government's desire to lure international investment. Tarapoa is only 40 km from the Columbian border, a violent area controlled by the Revolutionary Armed Forces of Columbia (FARC), a Marxist guerrilla group responsible for most of Columbia's kidnappings. In 1999, there were almost 200 kidnappings in Ecuador alone and thousand others in 1990s were taken hostage in Columbia. The kidnappers ideologically opposed the disparities of wealth created by the oil boom and spent their ransoms on weapons to fight against the government. This book presents a detailed account of the kidnapping from the hostages perspective and describes the efforts made by United Pipeline Systems and the Department of Foreign Affairs to bring the workers safely home after 100 days in captivity. The theory is that the kidnappers, still unidentified at the time that this book was published, either belonged to FARC (or an Ecuadorian offshoot FARE) or they were common, well organized bandits with no political affiliation.

    Single nucleotide polymorphisms (SNPs) are the most frequent type of genetic variation in the human genome, and are of interest for the study of susceptibility to and protection from diseases. The haplotype at chromosome 19q13.2-3 encompassing the three SNPs ASE-1 G-21A, RAI IVS1 A4364G and ERCC1 Asn118Asn have been associated with risk of breast cancer and lung cancer. Haplotype carriers are defined as the homozygous carriers of RAI IVS1 A4364G A , ERCC1 Asn118Asn T and ASE-1 G-21A G . We aimed to evaluate whether the three polymorphisms and the haplotype are associated to risk of colorectal cancer, and investigated gene-environment associations between the polymorphisms and the haplotype and smoking status at enrolment, smoking duration, average smoking intensity and alcohol consumption, respectively, in relation to risk of colorectal cancer. Associations between the three individual polymorphisms, the haplotype and risk of colorectal cancer were examined, as well as gene-environment interaction, in a Danish case-cohort study including 405 cases and a comparison group of 810 persons. Incidence rate ratio (IRR) were estimated by the Cox proportional hazards model stratified according to gender, and two-sided 95% confidence intervals (CI) and p-values were calculated based on robust estimates of the variance-covariance matrix and Wald's test of the Cox regression parameter. No consistent associations between the three individual polymorphisms, the haplotype and risk of colorectal cancer were found. No statistically significant interactions between the genotypes and the lifestyle exposures smoking or alcohol consumption were observed. Our results suggest that the ASE-1 G-21A, RAI IVS1 A4364G and ERCC1 Asn118Asn polymorphisms and the previously identified haplotype are not associated with risk of colorectal cancer. We found no evidence of gene-environment interaction between the three polymorphisms and the haplotype and smoking intensity and alcohol consumption

    This image is a mosaic of day and night infrared images of Melas Chasma taken by the camera system on NASA's Mars Odyssey spacecraft. The daytime temperature images are shown in black and white, superimposed on the martian topography. A single nighttime temperature image is superimposed in color. The daytime temperatures range from approximately -35 degrees Celsius (-31 degrees Fahrenheit) in black to -5 degrees Celsius (23 degrees Fahrenheit) in white. Overlapping landslides and individual layers in the walls of Melas Chasma can be seen in this image. The landslides flowed over 100 kilometers (62 miles) across the floor of Melas Chasma, producing deposits with ridges and grooves of alternating warm and cold materials that can still be seen. The temperature differences in the daytime images are due primarily to lighting effects, where sunlit slopes are warm (bright) and shadowed slopes are cool (dark). The nighttime temperature differences are due to differences in the abundance of rocky materials that retain their heat at night and stay relatively warm (red). Fine grained dust and sand (blue) cools off more rapidly at night. These images were acquired using the thermal infrared imaging system infrared Band 9, centered at 12.6 micrometers.Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the 2001 Mars Odyssey mission for NASA's Office of Space Science in Washington, D.C.

  1. The day of the yam.

    Science.gov (United States)

    Rosser, A

    Yam, the staple food in several tropical countries, is a good source of the steroid used in the manufacture of the pill and other sex hormone preparations -- saponin diosgenin. In the early days of production of oral contraceptives (OCs), most yams were gathered from the wild in Mexico. The type richest in steroids takes 3 years to mature and its cultivation has become something of an art. Yams grow best in light, well-drained soil, and for this reason are grown in mounds which have been heavily manured. Propagation is by planting the tops or heads or by small portions of the tuber which is a swollen shoot. Other varieties are planted before the onset of the rains and the crop harvested about 8 months later. In 1970 the Mexican government nationalized the yam industry as a safeguard. This pushed up prices and the drug companies looked elsewhere for a cheap source. Although Mexico still remains the principal grower, India, South Africa, and the Far East supply the industry with plant origin steroids. As more than 90% of the hefty yam tubers consist of water, well over 100,000 tons have to be harvested every year to provide the 600-700 tons of the saponin diosgenin used by the drug companies. In China, where Western corticosteroids are regarded as too expensive for the barefoot doctors, several species of yam are used. Research has been going on to find another source of diosgenin and the most promising seems to be fenugreek, Trigonella foenumgraecum. "Foenum graecum" is Latin for Greek hay and was used by the early Greeks as a culinary and medicinal herb throughout the Mediterranean area. The richness of fenugreek was used to improve the roundness of women's breasts and to stimulate the flow of milk. Bath University has spent 10 years researching the development of a species of fenugreek which will yield large amounts of diosgenin. A certain amount of steroids come from animal sources. Such steroids are given when there is an adverse reaction from the

A colleague introduced Irwin to the satellite imagery thathe was exploring, demonstratinghow these images are a strong complement to field work. The sharing of this satellite data with nearby villages helped to show the encroachment of agriculture and the necessity of connecting space to the village. Satellite imagery also played a role in archeological endeavors, uncovering dozens of Mayan cities that have been buried for over a millennia by vegetation, and it provided evidence that the fall of the Mayan civilization may have been due to massive deforestation that ledto drought.Glacial retreat in Chile imaged by ISERV.Irwin displayed the constellation of NASAs Earth-monitoring satellites that have played an integral role in conserving our planet and alerting the world of natural disasters.

    Full Text Available A tricomoníase é uma protozoose causada pelo Trichomonas vaginalis, que desencadeia uma ampla variedade de manifestações clínicas, podendo estar associada à transmissão do vírus da imunodeficiência humana, câncer cervical, infertilidade, entre outros. No Brasil, a incidência varia entre 20 e 40%. A via primária de transmissão é pelo contato sexual e o diagnóstico laboratorial pode ser realizado através da Reação de Polimerase em Cadeia (PCR, isolamento em meios de cultura e exame do conteúdo vaginal à fresco e/ou corados pelos métodos de Giemsa e Papanicolau. Esse último possui limitações na detecção de patologias consideradas DST, a exemplo da tricomoníase. Esse artigo trata da prevalência de tricomoníase em mulheres usuárias dos laboratórios conveniados ao Ministério da Saúde, na faixa etária de 19 a 44 anos, que foram submetidas ao teste de Papanicolau, em 2004-2005, no Estado de Sergipe. Os resultados revelaram que, em 206.034 usuárias, 7.349 apresentaram tricomoníase, sendo que 3.788 em 2004 e 3.498 em 2005. Observou-se que a prevalência estimada em Sergipe, no biênio estudado, não corrobora com a realidade brasileira, fato esse que pode estar atrelado ao diagnóstico executado.Trichomoniasis is a disease caused by the protozoan Trichomonas vaginalis, which initiates a wide variety of clinical manifestations. It may be associated with human immunodeficiency virus, cervical cancer, infertility and other diseases. Its incidence ranges from 20% up to 40% in Brazil. The primary channel of transmission is by sexual contact and laboratorial diagnostic may be performed by chain polymerase reaction (CPR, culture medium isolation, fresh vaginal content exam and/or colored by Giemsa and Papanicolau methods. The later has limitations in the detection of pathologies considered sexually transmissible, like Thricomoniasis.

    Full Text Available INTRODUÇÃO: O objetivo do presente estudo é apresentar revisão da prevalência e dos principais mecanismos fisiopatológicos que levam a formação da litíase biliar em pacientes submetidos a transplante de órgãos. MÉTODOS: Revisão da literatura abrangendo 29 publicações obtidas das bases Medline/Pubmed, Scielo e Lilacs com cruzamento dos unitermos "transplante, transplante renal, transplante hepático, cálculo biliar, colecistite.". Vários estudos que utilizaram a ultrassonografia demonstraram aumento na prevalência da litíase biliar em pacientes submetidos a transplante de órgãos. A taxa de formação de cálculos novos após o transplante variou de 10 a 55% e a total (cálculos formados antes e após o transplante de 17 a 68%. Tanto o ganho como a perda de peso rápida, que podem ocorrer após o transplante, predispõem à formação de cálculos biliares. O uso do imunossupressor ciclosporina é considerado como o principal fator que aumenta a incidência de litíase biliar após o transplante. CONCLUSÃO: A prevalência de litíase biliar é maior nos pacientes submetidos a transplante de órgãos do que na população geral. As principais alterações que ocorrem no paciente transplantado que predispõem a formação dos cálculos são as alterações do peso corporal, uso de imunossupressores, diabete melito e hiperlipidemia.INTRODUCTION: The objective of the present study is to review the prevalence and the main physiopathologic mechanisms that result in gallstone formation in transplant patients. METHODS: Literature review with 29 papers included in Medline/Pubmed, Scielo and Lilacs database, crossing key-words "transplantation; kidney transplantation; liver transplantation; gallstone; cholecystitis". Several ultrasonographic studies have demonstrated an increase in gallstone prevalence in transplant patients. The formation rate of new stones after transplantation varied from 10 to 55% and the rate of total stones

It is a huge zoo with about a quarter million zookeepers, they are citizen astronomers who collaboratively classify galaxies by their looks as an attempt to understand galaxy evolution. The big question that is being answered is: how do blue, actively star-forming galaxies evolve into red, quiescent (non-star-forming) galaxies? The Zoo helped reveal that blue galaxies turn into red galaxies via two possible paths galaxies might run out of supply of gas and shut off star formation slowly; or they could merge with one another and turn off star formation by destroying the gas reservoir rapidly!The Galaxy Zoo project also led to the discoveries of:Green Peas: they are the living fossils of galaxy evolution; compact, bright, green galaxies that are actively forming starsOverlapping galaxies: they are pairs of galaxies that are separated physically but happen to lie on the same line of sight; they provide excellent laboratories for studying dust extinctionHannys Voorwerp: an unusual object named after Hanny the discoverer, which is believed to be the first detection of quasar light echoThe idea of Galaxy Zoo in getting help from citizen scientists was further extended into an award-winningproject known as the Zooniverse, which is an online platform for streamlined crowd-sourcing for scientific research that requires human input.

If you said Wikipedia, youre not alone. For many people, Wikipedia is the primary source of information about astronomy and science. However, many Wikipedia articles about science topics are incomplete or missing, and women are underrepresented among scientists with biographies.To address this, the AAS Astronomy Education Board teamed up with the Wiki Education Foundation to host an edit-a-thon as part of the Wikipedia Year of Science. More than forty attendees spent the better part of three hours working through tutorials, creating new articles, and editing existing ones. The session was generously sponsored by the Simons Foundation.The Year of Science initiative seeks to bring Wikipedia editing skills to the classroom and help new editors find sustainable ways to contribute to Wikipedia in the long term. Anybody can create a free account and start editing!As a first-time Wikipedia contributor, I took the time to go through nearly all the tutorial exercises and familiarize myself with the process of editing a page. I decided to flesh out one section in an existing page about asteroseismology. Others created biography pages from scratch or selected various astronomical topics to write about. To me, the editing process felt like a cross between writing a blog post and a journal article, in a hack day type environment. Working through the tutorial and some examples renewed my empathy for learners who are tackling a new skill set for the first time. A full summary of our

    Full Text Available FUNDAMENTOS: A neurite silenciosa é definida como deterioração da função nervosa na ausência de dor neural, diferenciando-se da neurite franca, em que ocorre dor no nervo periférico, com ou sem prejuízo da função nervosa. Sua detecção precoce é importante para tentar impedir o estabelecimento de seqüelas decorrentes da hanseníase. OBJETIVOS: Conhecer a freqüência das neurites silenciosas em portadores de formas multibacilares de hanseníase. MÉTODOS: Cento e três pacientes (18,4% BB, 47,6% BL e 34% LL foram acompanhados durante o período médio de 64,6 meses a partir do momento do diagnóstico, durante e após a poliquimioterapia, por meio da avaliação do grau de incapacidade. RESULTADOS: Foram analisados doentes que tiveram piora do grau de incapacidade no término de tratamento, ou ao fim do seguimento, em relação ao grau manifestado antes do tratamento ou no término do tratamento medicamentoso. Ao todo, pelo menos cinco pacientes (4,9% do total evoluíram com neurite silenciosa, durante ou após a poliquimioterapia. CONCLUSÃO: Preconiza-se exame neurológico seqüencial cuidadoso dos pacientes multibacilares, de modo a detectar e tratar precocemente a neurite silenciosa.

    Full Text Available OBJETIVO: Apresentar os achados na tomografia computadorizada de alta resolução (TCAR do tórax da microlitíase alveolar pulmonar. MÉTODOS: Foram estudadas, retrospectivamente, as tomografias de dez pacientes adultos, sete mulheres e três homens, com idade média de 38,7 anos. Os exames foram analisados por dois radiologistas, de forma independente, e as decisões finais foram obtidas por consenso. RESULTADOS: Os achados mais freqüentes foram as opacidades em vidro fosco e as calcificações subpleurais, ambas presentes em 90% dos pacientes estudados. Os outros achados de maior relevância foram pequenos nódulos parenquimatosos, calcificação ao longo dos septos interlobulares, cissuras nodulares, nódulos subpleurais, cistos subpleurais, consolidações densas e padrão de pavimentação em mosaico. CONCLUSÕES: A microlitíase alveolar pulmonar apresenta aspectos na TCAR que são altamente sugestivos da doença, na maior parte dos casos dispensando a realização de biópsias pulmonares.OBJECTIVE: To present the high-resolution computed tomography (HRCT findings of pulmonary alveolar microlithiasis. METHODS: The HRCT scans of 10 adult patients (seven females and three males; mean age, 38.7 years were retrospectively analyzed. The films were studied independently by two radiologists. RESULTS: The most common tomographic findings were ground-glass attenuation and linear subpleural calcifications, which were seen in 90% of the patients. Other relevant findings were small parenchymal nodules, calcification along the interlobular septa, nodular cissures, subpleural nodules, subpleural cysts, dense consolidations, and a mosaic pattern of attenuation. CONCLUSIONS: The HRCT findings presented by individuals with pulmonary alveolar microlithiasis are distinct. In most cases, such findings can form the basis of the diagnosis, eliminating the need to perform a lung biopsy.

This talk featured a broad range of research efforts on exoplanets, with the main focus on how we study the composition of their atmospheres, and how multi-body interactions carve the structure of the planetary systems we observe.One of her first points is the well-known idea that the Solar System is an oddball, compared to the exoplanet systems we have found so far: most of these systems contain hot Jupiters and mini-Neptunes at very close-in orbits around their host stars. Moreover, even when studying their transmission spectra, it is difficult to know the exact composition of their atmospheres.Knutson: it is difficult to constrain atmospheric composition of exoplanets (H-poor or H-rich+clouds?) #aas228pic.twitter.com/LdyN4o9RC7 astrobites (@astrobites) June 15, 2016The main proposal on how these systems formed is the migration scenario. In order to validate this idea, Dr. Knutson and her group The Friends of Hot Jupiters study systems with close-in gas giants and their frequency of binary companions, which are supposed to be the main culprits causing gas-giant migration. They found that approximately half of the observed systems have long-distance companions, providing strong validation of the migration scenario. Moreover, Dr. Knutson speculates that wide binaries have more

Risa set the stage with an elaborate description of the current accepted facts in the era of precision cosmology including the standard model of concordance cosmology, described by seven parameters and an accepted Lambda-CDM paradigm (with a cosmological constant and cold dark matter). The talk stressed on the fact that all these parameters are understood to a percent order precision, which is a remarkable deviation from the time in 1990s when according to Risa, Alan Guth never thought that any of these numbers could be measured precisely!Risa Wechsler describing our current constraints on what Dark Matter could constitute.Joseph Silk discussing limits on cosmological parameters.The CMB measurements, Big Bang Nucleosynthesis estimates and galaxy clustering statistics all contribute to locking down the description of our universe. She emphasized on the tensions between different probes to measure expansion rate H0 of the universe, and small scale predictions of cold dark matter simulations, but she is hopeful that these shall be resolved eventually. Joe Silk followed this up with his interpretation of trying to understand our place in the universe and placing limits on different parameters and

A determinação da soroprevalência de anticorpos contra PGL-I através de estudos com crianças em idade escolar foi sugerida como indicador útil da taxa de prevalência da hanseníase a nível municipal.Para investigar se a soropositividade estaria associada aos coeficientes de detecção da hanseníase e se poderia ser usada como indicador da prevalência em outras áreas, 7.073 crianças em três estados endêmicos de hanseníase no Brasil foram testadas. Resultados mostram uma considerável variação da distribuição de soropositividade nas comunidades, independente do número de casos de hanseníase detectados. A soroprevalência foi significativamente menor nos colégios. Nenhuma diferença na distribuição da soropositividade determinada por ELISA ou dipstick foi observada. Nenhuma correlação entre o coeficiente de detecção da hanseníase e soropositividade pôde ser estabelecida.Leprosy control programs would benefit expressively from an easy method to estimate disease prevalence and to assess the effect of leprosy control measures on disease prevalence. Determination of the seroprevalence of antibodies to PGL-I through school children surveys might be a useful indicator of leprosy prevalence at the district level. To investigate whether seropositivity rates could be related to leprosy detection rates and whether seropositivity could be used as a proximal indicator to predict the leprosy incidence in other areas, 7,073 school children in three different leprosy-endemic states in Brazil were tested. The results show a widely varying distribution of seropositivity in the communities independent of the number of leprosy cases detected. Seroprevalence was significantly lower at private schools. No differences in the patterns of seropositivity between ELISA

A ecoendoscopia (EE é excelente no diagnóstico da pancreatite crônica incipiente e microcálculos da vesícula biliar (MCV ou colédoco. São poucas as referências na literatura internacional e nenhuma na nacional a respeito do emprego da EE na PA. O objetivo deste trabalho é o de estabelecer o valor da EE no diagnóstico da colecistomicrolitíase em doentes com PA sem causa aparente. MÉTODOS: Trinta e seis pacientes com o diagnóstico de PA sem causa aparente foram consecutivamente estudados durante cinco anos. Dos enviados para exame ecoendoscópico, 21 mulheres e 15 homens com média de idade de 41,6 anos. Todos haviam sido submetidos antes a pelo menos um US e uma TC, que não revelaram alterações na via bílio-pancreática e 63,9% deles tinham apresentado mais de um episódio de PA. O diagnóstico da colecistomicrolitíase pela EE realizada até uma semana durante o surto de PA baseou-se no tamanho do cálculo (até 3 mm, inclusive e hiperecogeneicidade com ou sem sombra acústica. Todos os doentes foram colecistectomizados, após o exame ecoendoscópico. RESULTADO: O exame das peças cirúrgicas mostrou que 27 (75% doentes apresentavam MCV e nove (25% não. A EE levou a erro no diagnóstico da microlitíase em seis (16,8% casos, quatro casos de falsos-positivos e dois casos de falsos-negativos. Em 30 casos (83,2% houve confirmação dos seus resultados.

    Vinge, Lotte; Jakobsen, Johannes; Pedersen, Asger Roer; Andersen, Henning

    2016-01-01

    In patients with myasthenia gravis (MG), muscle strength is expected to decrease gradually during the day due to physical activities. Isometric muscle strength at the shoulder, knee, and ankle was determined in 10 MG patients (MGFA class II-IV) who were receiving usual medical treatment and in 10 control subjects. To determine diurnal and day-to-day variation, muscle strength was measured 4 times during day 1 and once at day 2. Knee extension strength decreased during the day in both patients and controls. Neither diurnal nor day-to-day variation of muscle strength was higher in patients compared with controls. Patients with mild to moderate MG did not have increased variation of isometric muscle strength during the day or from day-to-day compared with controls. This suggests that isometric muscle performance can be determined with high reproducibility in similar groups of MG patients without regard to time of day. © 2015 Wiley Periodicals, Inc.

    Full Text Available INTRODUÇÃO: a anseníase multibacilar pode causar comprometimento da mucosa oral, com ou sem lesões aparentes. Há poucos estudos que tratam deste assunto na era da multidrogaterapia. OBJETIVO: Verificar a freqüência do comprometimento da mucosa oral em pacientes de hanseníase multibacilar. CASUÍSTICA E MÉTODOS: Foi realizado um estudo transversal em vinte pacientes de hanseníase multibacilar, não-tratados, atendidos consecutivamente em Dracena, São Paulo, entre o período de 2000 e 2002. Foi realizado exame clínico completo da mucosa oral. Os pacientes foram submetidos a biópsias na mucosa jugal, na língua e no palato mole, em alteração ou em pontos pré-estabelecidos. Os cortes foram corados pelas técnicas da hematoxilina-eosina e Ziehl-Neelsen. O encontro de granuloma e bacilos álcool-ácido-resistentes ao exame histopatológico determinou o comprometimento específico. RESULTADOS: O estudo envolveu 19 pacientes multibacilares com tempo médio de evolução de 2,5 anos. Ocorreu comprometimento histopatológico específico em apenas um paciente virchowiano, com mucosa oral clinicamente normal, na língua e no palato mole. CONCLUSÕES: 1. Alteração clínica na mucosa oral não implica em comprometimento pela doença, é necessário confirmação histopatológica. 2. Alterações clínicas específicas aparentes são raras. 3. A mucosa oral clinicamente normal pode exibir comprometimento histopatológico específico.INTRODUCTION: Multibacillary leprosy may involve the oral mucosa, with or without apparent lesions.

    Full Text Available Contribui-se com o sistema de Vigilância Epidemiológica em nível local por meio de análise espacial em razão do predomínio do caráter urbano da hanseníase em nosso meio e por sua distribuição não homogênea - em parte, pela forma de ocupação e transformação do espaço urbano. Trabalha-se o conceito de risco coletivo pela definição de micro-áreas homogêneas mediante o indicador de carência social, verificando-se sua coerência com padrões da distribuição da hanseníase obtidos da base de dados do SINAN para o Município de Olinda no período 1991-96. Para cada estrato, definido segundo níveis semelhantes dos indicadores, foi calculado o coeficiente de detecção médio para o período. Ao exame da associação entre carência social (risco e coeficiente de detecção de hanseníase obteve-se coeficiente de explicação de 66,1% no modelo multiplicativo, acrescido para 84,3% com a variável renda. Para atender à lógica de intervenção, definiram-se estratos de alto, médio e baixo risco nos distritos sanitários e área programática. A construção desses mapas mostrou-se útil a instrumentalizar o planejamento em nível local.In the State of Pernambuco, Brazil, leprosy has been mainly an urban disease, with an uneven geographical distribution related at least partially to the way urban space has been occupied and transformed. Spatial analysis may thus become an important tool to establish an epidemiological surveillance system for leprosy. Homogeneous micro-areas were defined in the city of Olinda through the integration of two databases, the Population Census and SINAN, and through the use of digital maps and geoprocessing techniques. Census tracts were classified according to a social deprivation index (SDI, and micro-area homogeneity was based on similar values for this indicator. Cluster analysis (K-means was used to define cut-offs between strata. The same procedure was repeated using the income variable only

The current ICRP proposal to abandon the 10-day option in diagnostic radiography is outlined and some reasons for this action by the ICRP are proposed, including the fact that the most sensitive period for radiation damage to the developing foetus brain is at 10-18 weeks after the first day of the last menstrual period.

    In a 1964 decision the National Health and Medical Research Council recommended that radiological examinations of the lower abdomen and pelvis of women of childbearing age should be confined to the 10-day interval following the onset of menstruation. Recent evidence suggests that the first four weeks from the first day of the last menstrual period is not a critically radiosensitive period and consequently strict adherence to the ten-day rule is no longer indicated

    Indirect calorimetry is a common and noninvasive method to estimate rate of fat oxidation (FatOx) during exercise, and test-retest reliability should be considered when interpreting results. Diet also has an impact on FatOx. The aim of the present study was to investigate day to day variations in FatOx during moderate exercise given the same diet and 2 different isoenergetic diets. Nine healthy, moderately-trained females participated in the study. They performed 1 maximal oxygen uptake test and 4 FatOx tests. Habitual diets were recorded and repeated to assess day to day variability in FatOx. FatOx was also measured after 1 day of fat-rich (26.8% carbohydrates (CHO), 23.2% protein, 47.1% fat) and 1 day of CHO-rich diet (62.6% CHO, 20.1% protein, 12.4% fat). The reliability test revealed no differences in FatOx, respiratory exchange ratio (RER), oxygen uptake, carbon dioxide production, heart rate, blood lactate concentration, or blood glucose between the 2 habitual diet days. FatOx decreased after the CHO-rich diet compared with the habitual day 2 (from 0.42 ± 0.15 to 0.29 ± 0.13 g·min(-1), p diet and the 2 habitual diet days. FatOx was 31% lower (from 0.42 ± 0.14 to 0.29 ± 0.13 g·min(-1), p diet compared with the fat-rich diet. Using RER data to measure FatOx is a reliable method as long as the diet is strictly controlled. However, even a 1-day change in macronutrient composition will likely affect the FatOx results.

Doze pacientes com essas seqüelas participaram da pesquisa, separados aleatoriamente em dois grupos: o grupo FNP, tratado com facilitação neuromuscular proprioceptiva, e o grupo AEP, com alongamento estático passivo. Ambos realizaram dez sessões de alongamentos, sendo submetidos à avaliação inicial e final nas quais foram aplicados o questionário SF-36, mensuradas a amplitude de movimento (ADM do punho e tornozelo, testados os reflexos e a sensibilidade. No grupo FNP foi observada melhora na ADM do tornozelo e em três domínios do SF-36; no grupo AEP, em cinco domínios do SF-36. Quando comparados os grupos, o FNP obteve melhora significativa na extensão do punho, dorsiflexão e plantiflexão em relação ao AEP. A facilitação neuromuscular proprioceptiva parece ser um método mais eficaz para ganhar alongamento muscular e ADM de tornozelo e punho em pacientes com seqüelas de hanseníase. Não foi observada relação entre acréscimo na ADM e melhora na qualidade de vida relacionada à saúde nos pacientes dos dois grupos.The purpose of this study was to compare the effects of two kinds of stretching - passive, static stretching, and proprioceptive neuromuscular facilitation (PNF - in patients with leprosy sequel.

    The identification of patients at high risk of unplanned readmission is an important component of discharge planning strategies aimed at preventing unwanted returns to hospital. The aim of this study was to investigate the factors associated with unplanned readmission in a Sydney hospital. We developed and compared validated readmission risk scores using routinely collected hospital data to predict 7-day, 30-day and 60-day all-cause unplanned readmission. A combination of gradient boosted tree algorithms for variable selection and logistic regression models was used to build and validate readmission risk scores using medical records from 62,235 live discharges from a metropolitan hospital in Sydney, Australia. The scores had good calibration and fair discriminative performance with c-statistic of 0.71 for 7-day and for 30-day readmission, and 0.74 for 60-day. Previous history of healthcare utilization, urgency of the index admission, old age, comorbidities related to cancer, psychosis, and drug-abuse, abnormal pathology results at discharge, and being unmarried and a public patient were found to be important predictors in all models. Unplanned readmissions beyond 7 days were more strongly associated with longer hospital stays and older patients with higher number of comorbidities and higher use of acute care in the past year. This study demonstrates similar predictors and performance to previous risk scores of 30-day unplanned readmission. Shorter-term readmissions may have different causal pathways than 30-day readmission, and may, therefore, require different screening tools and interventions. This study also re-iterates the need to include more informative data elements to ensure the appropriateness of these risk scores in clinical practice.

    Intra day electricity markets contribute to facilitate transition from conventional sources to renewable which need to be balanced on real-time basic due to the unpredictable nature of weather. This paper describes the way from regional electricity markets to a single pan-european market model which is target model of the European Commission. Single liquid intra day electricity market where market participants can balance their portfolios is prerequisite to a full utilisation of renewable power sources and a solution for some problems experienced by TSOs with loop and parallel flows from neighbouring countries. Integrated German and French intra day electricity market which uses Flexible Intra day Trading Scheme is described in this paper as a market which could be extended further to the CEE region with very poor liquidity of its local intra day markets.

A limited number of 16 patients (of which 11 belonged to lepromatous leprosy and five to tuberculoid leprosy and eight healthy individuals were included for the present study. The number of urine samples positive by PCR were 36.4% (4/11 in lepromatous patients and 40% (2/5 in tuberculoid patients. None of the samples from healthy individuals was positive. To our knowledge, the results indicate, for the first time, the presence of M. leprae DNA in urine from leprosy patients. Another important finding obtained out of the study is that amongst treated patients 66.6% (4/6 were positive whereas amongst untreated only 20% (2/10 were positive. From the present indicative data it appears that treatment improves the PCR results with urine as a sample. Thus, the approach could prove to be useful for monitoring the treatment response of individual patients and needs to be further evaluated with a large number of patients.Pesquisamos o DNA do Mycobacterium leprae para proteína 36 kDa na urina usando a técnica do PCR específica para M. leprae.

    We report here on the software Hack Day organised at the 2014 SPIE conference on Astronomical Telescopes and Instrumentation in Montréal. The first ever Hack Day to take place at an SPIE event, the aim of the day was to bring together developers to collaborate on innovative solutions to problems of their choice. Such events have proliferated in the technology community, providing opportunities to showcase, share and learn skills. In academic environments, these events are often also instrumental in building community beyond the limits of national borders, institutions and projects. We show examples of projects the participants worked on, and provide some lessons learned for future events.

    A simple answer to the question “Who are Seventh-day Adventists?” can be stated briefly: the Seventh-day Adventist Church (or in Croatia, Christian Adventist Church) is a worldwide body of more than 10 million Christians who observe Saturday as the Sabbath and expect Jesus’ second coming soon. In more detail, one might say that Seventh- day Adventists are a conservative Protestant body of evangelical Christians whose faith is grounded in the Bible and centered on Jesus, with stress on His ato...

    Taking the 32 sudden storm commencements (SSC) listed by the observatory de l'Ebre / ISGI over the year 2002 (maximal solar activity) as a starting point, we performed a statistical analysis of the related solar sources, solar wind signatures, and terrestrial responses. For each event, we characterized and identified, as far as possible, (i) the sources on the Sun (Coronal Mass Ejections -CME-), with the help of a series of criteria (velocities, drag coefficient, radio waves, magnetic field polarity), as well as (ii) the structure and properties in the interplanetary medium, at L1, of the event associated to the SSC: magnetic clouds -MC-, non-MC interplanetary coronal mass ejections -ICME-, co-rotating/stream interaction regions -SIR/CIR-, shocks only and unclear events that we call "miscellaneous" events. The geoeffectiveness of the events, classified by category at L1, is analysed by their signatures in the Earth ionized (magnetosphere and ionosphere) and neutral (thermosphere) environments, using a broad set of in situ, remote and ground based instrumentation. The role of the presence of a unique or of a multiple source at the Sun, of its nature, halo or non halo CME, is also discussed. The set of observations is statistically analyzed so as to evaluate and compare the geoeffectiveness of the events. The results obtained for this set of geomagnetic storms started by SSCs is compared to the overall statistics of year 2002, relying on already published catalogues of events, allowing assessing the relevance of our approach ; for instance all the 12 well identified Magnetic Clouds of 2002 give rise to SSCs.

The categorization of the events at L1 is made on published catalogues. For each potential CME/L1 event association we compare the velocity observed at L1 with the one observed at the Sun and the estimated balistic velocity. Observations of radio emissions (Type II, Type IV detected from the ground and /or by WIND) associated to the CMEs make the solar source more probable. We also compare the polarity of the magnetic clouds with the hemisphere of the solar source. The drag coefficient (estimated with the drag-based model) is calculated for each potential association and it is compared to the expected range values. We identified a solar source for 26 SSC related events. 12 of these 26 associations match all criteria. We finally discuss the difficulty to perform such associations.

  17. The Sun-Earth connect 3: lessons from the periodicities of deep time influencing sea-level change and marine extinctions in the geological record.

    A number of papers since Rampino and Stothers published in Science 1984 have reported common periodicities in a wide range of climate, geomagnetic, tectonic and biological proxies, including marine extinctions. Single taper and multitaper spectral analysis of marine fluctuations between the Late Cretaceous and the Miocene replicates a number of the published harmonics. Whereas these common periodicities have been argued to have a galactic origin, this paper presents an alternative fractal model based on large scale fluctuations of the magnetic field of the Sun. The fluctuations follow a self-similar matrix of periodicities and the solutions of the differential equation allow for models to be constructed predicting extreme events for solar emissions. A comparison to major Phanerozoic extinction, climate and geomagnetic events, captured in the geological record, show a striking loop symmetry summarised in major 66 Ma irradiance and electromagnetic pulses from the Sun.

  19. The Sun-Earth connect 2: Modelling patterns of a fractal Sun in time and space using the fine structure constant

    Self-similar matrices of the fine structure constant of solar electromagnetic force and its inverse, multiplied by the Carrington synodic rotation, have been previously shown to account for at least 98% of the top one hundred significant frequencies and periodicities observed in the ACRIM composite irradiance satellite measurement and the terrestrial 10.7cm Penticton Adjusted Daily Flux data sets. This self-similarity allows for the development of a time-space differential equation (DE) where the solutions define a solar model for transmissions through the core, radiative, tachocline, convective and coronal zones with some encouraging empirical and theoretical results. The DE assumes a fundamental complex oscillation in the solar core and that time at the tachocline is smeared with real and imaginary constructs. The resulting solutions simulate for tachocline transmission, the solar cycle where time-line trajectories either 'loop' as Hermite polynomials for an active Sun or 'tail' as complementary error functions for a passive Sun. Further, a mechanism that allows for the stable energy transmission through the tachocline is explored and the model predicts the initial exponential coronal heating from nanoflare supercharging. The twisting of the field at the tachocline is then described as a quaternion within which neutrinos can oscillate. The resulting fractal bubbles are simulated as a Julia Set which can then aggregate from nanoflares into solar flares and prominences. Empirical examples demonstrate that time and space fractals are important constructs in understanding the behaviour of the Sun, from the impact on climate and biological histories on Earth, to the fractal influence on the spatial distributions of the solar system. The research suggests that there is a fractal clock underpinning solar frequencies in packages defined by the fine structure constant, where magnetic flipping and irradiance fluctuations at phase changes, have periodically impacted on the Earth and the rest of the solar system since time immemorial.
