  13. Program report: FY 1976, Atmospheric and Geophysical Sciences Division, Physics Department

    International Nuclear Information System (INIS)

    The Atmospheric Release Advisory Capability (ARAC), with its central facility located at LLL, is meeting the long-term need for rapid and accurate regional dose-to-man estimates of nuclear material released as a result of accidents, operations, or terrorism acts. During the past two years, ARAC has been used in four potential WARMSPOT events and for one accidental release. Continuing research, in terms of new modeling techniques, simulation of regional tracer experiments, and other verification activities, support this capability. Emergency response is currently being upgraded to evaluate the consequences of atmospheric releases at selected nuclear facilities and for potential acts of nuclear terrorism anywhere in the Northern Hemisphere. Regional modeling was also applied in monitoring SO2-sulfate concentrations in the northeastern USA

  15. Dynamics in Atmospheric Physics

    Science.gov (United States)

    Lindzen, Richard A.

    2005-08-01

    Motion is manifest in the atmosphere in an almost infinite variety of ways. In Dynamics in Atmospheric Physics, Dr. Richard Lindzen describes the nature of motion in the atmosphere, develops fluid dynamics relevant to the atmosphere, and explores the role of motion in determining the climate and atmospheric composition. The author presents the material in a lecture note style, and the emphasis throughout is on describing phenomena that are at the frontiers of current research, but due attention is given to the methodology of research and to the historical background of these topics. The author's treatment and choice of topics is didactic. Problems at the end of each chapter will help students assimilate the material. In general the discussions emphasize physical concepts, and throughout Dr. Lindzen makes a concerted effort to avoid the notion that dynamic meteorology is simply the derivation of equations and their subsequent solution. His desire is that interested students will delve further into solution details. The book is intended as a text for first year graduate students in the atmospheric sciences. Although the material in the book is self contained, a familiarity with differential equations is assumed; some background in fluid mechanics is helpful.

  6. A Department of Atmospheric and Planetary Sciences at Hampton University

    Paterson, W. R.; McCormick, M. P.; Russell, J. M.; Anderson, J.; Kireev, S.; Loughman, R. P.; Smith, W. L.

    2006-12-01

    With this presentation we discuss the status of plans for a Department of Atmospheric and Planetary Sciences at Hampton University. Hampton University is a privately endowed, non-profit, non-sectarian, co-educational, and historically black university with 38 baccalaureate, 14 masters, and 4 doctoral degree programs. The graduate program in physics currently offers advanced degrees with concentration in Atmospheric Science. The 10 students now enrolled benefit substantially from the research experience and infrastructure resident in the university's Center for Atmospheric Sciences (CAS), which is celebrating its tenth anniversary. Promoting a greater diversity of participants in geosciences is an important objective for CAS. To accomplish this, we require reliable pipelines of students into the program. One such pipeline is our undergraduate minor in Space, Earth, and Atmospheric Sciences (SEAS minor). This minor concentraton of study is contributing to awareness of geosciences on the Hampton University campus, and beyond, as our students matriculate and join the workforce, or pursue higher degrees. However, the current graduate program, with its emphasis on physics, is not necessarily optimal for atmospheric scientists, and it limits our ability to recruit students who do not have a physics degree. To increase the base of candidate students, we have proposed creation of a Department of Atmospheric and Planetary Sciences, which could attract students from a broader range of academic disciplines. The revised curriculum would provide for greater concentration in atmospheric and planetary sciences, yet maintain a degree of flexibility to allow for coursework in physics or other areas to meet the needs of individual students. The department would offer the M.S. and Ph.D. degrees, and maintain the SEAS minor. The university's administration and faculty have approved our plan for this new department pending authorization by the university's board of trustees, which will

  7. High Energy Physics Departments - Overview

    International Nuclear Information System (INIS)

    Following the tradition, the activities of the seven new units created in 1997 on the basis of the former Department of High Energy Physics are presented under a common header, they are: Department of Particle Theory (Dept 5); Department of Leptonic Interactions (Dept 11); Department of Hadron Structure (Dept 12); Department of High Energy Nuclear Interactions (Dept 13); The ALICE Experiment Laboratory (NAL); The ATLAS Experiment Laboratory (NAT); High Energy Physics Detector Construction Group (PBD). The research covers a variety of problems of the experimental and theoretical high energy particle physics: the hadronic and leptonic interactions with nucleons and nuclei (characteristics of particle production, including heavy quark physics), e+e- interactions and tests of the Standard Model (also radiative corrections), ultrarelativistic heavy ion interactions and search for the quark-gluon plasma, as well as the spectra, composition and interactions of high energy cosmic ray particles. Research on detectors and accelerator components as well as the development of the apparatus for the high energy physics experiments at future accelerators: LHC (CERN, Geneva), RHIC (Brookhaven), B-Factory (KEK, Tsukuba) and TESLA (DESY) is also presented. The technology of new materials with unique properties such as carbon-carbon composites is also worked on from the point of view of their application in high energy physics experiments. The Division is located in a separate building on the campus of the University of Mining and Metallurgy (UMM). This location, close to the Jagiellonian University (JU), facilitates the collaboration with the latter and with the UMM. The joint weekly seminars carried out for nearly 40 years prove this long term tradition. A substantial part of the activities is teaching and training students from the academic community in Cracow. Joint research, teaching and academic training in the high energy physics are carried out within the M. Miesowicz Inter

    Cionco, Rodolfo G

    2012-01-01

    We present the proposal of an elective for engineering courses, designed to train professionals with a solid foundation in Physics of the Atmosphere interested in environmental and sustainability issues broadly. We propose four chapters that contain a variety of topics but strongly interrelated, which correspond to three main areas: nature of the atmosphere and meteorology relevant to contaminant transport, the dispersion of air pollutants and climate in general. We conclude that it is possible train engineers who understand the basic mechanisms that led to the current atmosphere, atmospheric processes related to local and global climate, the dispersion of air pollutants and key concepts such as solar activity, climatic change and climatic variability, even in one semester. It also discusses the relationship with other subjects and proposes and illustrates a method of course approval based on the performance of work directly applicable to engineering problems.

  18. Department of Cosmic Ray Physics - Overview

    International Nuclear Information System (INIS)

    Full text: The Department of Cosmic Ray Physics in Lodz is involved in basic research in the high energy Cosmic Ray field. Cosmic Rays are energetic particles from outside the Solar System. Most of the studies of Cosmic Rays address fundamental problems: · the nature of the physical and astrophysical processes responsible for high energies of particles · an estimation of the astrophysical conditions at the acceleration sites and/or search for sources of Cosmic Rays, · properties of high energy particle interactions at very high energies.

    Engineering studies were performed for the Zero-G Cloud Physics Experiment liquid cooling and air pressure control systems. A total of four concepts for the liquid cooling system was evaluated, two of which were found to closely approach the systems requirements. Thermal insulation requirements, system hardware, and control sensor locations were established. The reservoir sizes and initial temperatures were defined as well as system power requirements. In the study of the pressure control system, fluid analyses by the Atmospheric Cloud Physics Laboratory were performed to determine flow characteristics of various orifice sizes, vacuum pump adequacy, and control systems performance. System parameters predicted in these analyses as a function of time include the following for various orifice sizes: (1) chamber and vacuum pump mass flow rates, (2) the number of valve openings or closures, (3) the maximum cloud chamber pressure deviation from the allowable, and (4) cloud chamber and accumulator pressure.

    1978-01-01

    The paper presents the development background and the present status of the Atmospheric Cloud Physics Laboratory (ACPL) thermal control capability. The ACPL, a Spacelab payload, is currently in the initial flight hardware development phase for a first flight scheduled in June 1981. The ACPL is intended as a facility for conducting a wide variety of cloud microphysics experimentation under zero gravity conditions. The cloud chambers, which are key elements of the ACPL, have stringent thermal requirements. Thus the expansion chamber inner walls must be uniform to within + or - 0.1 C during both steady-state and transient operation over a temperature range of +30 to -25 C. Design progression of the expansion chamber, from early in-house NASA-MSFC concepts (including test results of a prototype chamber) to a thermal control concept currently under development, is discussed.

    In the Laboratory of Chemistry and Radiochemistry, research on chemistry of the transactinide elements 104(Rf), 105(Db) and 106(Sg) in model systems with their homologs (Zr, Hf, Nb, Ta, Mo, and W) was continued, and studies on ion-exchange and extraction behaviour of Tc, Re and Os as homologs of Bh(107) and Hs(108) were started. Basing on the law of periodicity, conditions for separation of superheavy elements Rf, Sg, and Bh were adjusted. A particularly important achievement was participation of our group in the third experiment in the world on aqueous chemistry of Sg, performed in the summer 1998 in GSI Darmstadt. The Environmental Radioactivity Laboratory, was continuing non-stop records of the ground-level atmospheric radioactivity. Besides, Pu content was determined in two-years collection of rainwater samples. An air monitoring station was recently equipped with a prototype γ-spectrometric scintillation system which, modem-coupled with the central server, will be tested in the Laboratory. For ultra-low-background measurements a muonic chamber was designed and made, and new spectrometer's background was recorded in various shielding configurations. Research on α-active and γ-active environmental contaminants in Antarctic samples, supplied by the Institute of Botany of the Jagiellonian University, resulted in an M.Sc. thesis defended in June 1998. Other cooperations of the Laboratory in 1998 have been the following: a) determination of 90Sr and 137Cs in wild animals bones (Institute of Nuclear Techniques, Technical University, Budapest, Hungary and Medical Academy, Bialystok, Poland); b) PIXE determinations of trace elements in ASS-500 air filters (Department 2 of the Institute) and mineralogical studies of collected dusts (Institute of Geological Sciences, Jagiellonian University and the Institute of Geography, Pedagogical University, Cracow); c) a-spectrometric determination of radium isotopes in river waters and bottom sediments (Institute of Geography

    Research in the Physics Department at Risoe National Laboratory covers three main fields: condensed matter physics, plasma physics and meteorology. The report is a progress report describing the principal activities in these fields for the period from 1 January to 31 December 1982. The condensed matter physics research is predominantly experimental utilising diffraction of neutrons, X-rays, and synchrotron X-ray radiation. The research topics range from studies of structure, excitations and phase transitions in model systems to studies of ion transport, texture and recrystallization kinetics with a more applied nature. The plasma physics research is partly experimental and partly theoretical. A study of pellet-plasma interaction is of applied nature and aimed at assessing the possibilities of refuelling a fusion reactor by shooting deuterium-tritium pellets into the plasma. A study of the fundamental physics of plasmas deals with investigations of wave propagation properties, instabilities, solitons, turbulence, etc. The research and applied work within meteorology lies within micrometereology and the subjects range from surface energy balance studies, over studies of the general structure of atmospheric coherence and boundary layer response to change in surface elevation, to specific studies of turbulent dispersion and deposition of airborne material. As part of the applied work within meteorology and wind energy, the test station for small windmills tests and licences windmills for the Danish market and offers consulting assistance for the Danish windmill manufacturers.

    A short account of the physics of electrical discharges in gases is given in view of its historical evolution and application to planetary atmospheres. As such it serves as an introduction to the articles on particular aspects of electric discharges contained in this book, in particular in the chapters on lightning and the violent discharges which in the recent two decades have been observed to take place in Earth's upper atmosphere. In addition of briefly reviewing the early history of gas discharge physics we discuss the main parameters affecting violent atmospheric discharges like collision frequency, mean free path and critical electric field strength. Any discharge current in the atmosphere is clearly carried only by electrons. Above the lower bound of the mesosphere the electrons must be considered magnetized with the conductivity becoming a tensor. Moreover, the collisional mean free path in the upper atmosphere becomes relatively large which lowers the critical electric field there and more easily ena...

    problems with DKFZ Heidelberg, where she participates in the development so called scanning collimators. As a result of a collaboration with LNF INFN Frascati, apart from two travelling wave RF structures now operated in the CTF3 experiment at CERN, one additional TW structure was made in our Department. It serves as an experimental unit for further study of TW technology. The collaboration with the DESY TESLA-FEL Project during the past years concerned mainly the RF accelerating super-conducting superstructures. This work ended with good results; it was reported in a common international oral session held during PAC2003 in Portland, USA. The superstructures have a chance to be mass-produced if the TESLA Superconducting Collider gets international financial approval. The work on RF vacuum windows upgrading against the multipactor effects in high power couplers was continued at DESY till the end of 2003. The original new technologies of thin TiN coating of ceramic windows were applied using newly constructed coating set-up. The summary of our 2003 results on coating will be presented in the TESLA Report 2004-02. A prerequisite of practising Accelerator Physics is understanding its importance in the wider context. Looking to professional literature on accelerators applications, one finds that in the developed world roughly 20000 accelerators exist (excluding electron units below 0.2 MeV) and yearly this number increases by at least 10%. More than half are used for material modification and roughly 30 % in radiotherapy. The most advanced technically and technologically are accelerators for subatomic physics and synchrotron radiation sources, where the total number of existing or under construction machines surpasses 200. New solutions, new technologies, cost reductions are still being investigated. So, in spite of difficult financial conditions, there is real motivation to keep accelerator physics alive in our Institute. (author)

    Full text: The main activities of the Department can be grouped into four parts: I. An ongoing analysis of data from large accelerator facilities At CERN SPS: The Compass experiment, ' a flagship of the CERN fixed target program ', studies the structure of the nucleon. Gluon polarization analysis was the main subject this year. Compass is an active experiment, and there is an ongoing effort in data taking and detector development. Two heavy ion experiments, WA98 and NA49, have finished data taking, but continue analysis. In 2008, important results on transverse momentum spectra were published. At COSY: The WASA experiment works with low energy (up to 3.7 GeV) beams of protons and deuterons, studying rare decays of eta mesons. New limits on branching ratios for such decays have been determined. This information is important for the theory of C and CP symmetry, and chiral perturbation theory. II. Preparations for soon-to-be-operating experiments at the LHC Three teams work on LHC experiments: CMS, LHCb and ALICE. The CMS experiment is ready for data taking. The muon trigger system, based on resistive plate chambers RPC, has been installed and tested using cosmic ray muons. Simulations of physical processes predicted by some extensions of the Standard Model were performed. The LHCb experiment team has worked on the system of the Inner Detector positioning station Rasnik, and the beam phase and intensity monitor (together with a P-III team). Simulations of the B decays into vector mesons, for the High Level Trigger, were performed. The ALICE team has worked on the installation of the photon detector PHOS and tests with cosmic muons. Simulations of neutral pion reconstruction were performed. Preparation of the computing base for future large experiments - work within the Worldwide LHC Computing Grid was actively pursued by a dedicated team. In 2008, many activities were directed at information and popularization of LHC physics. Our department members actively

    Terahertz (THz) radiation is extensively applied in diverse fields, such as space communication, Earth environment observation, atmosphere science, remote sensing and so on. And the research on propagation features of THz wave in the atmosphere becomes more and more important. This paper firstly illuminates the advantages and outlook of THz in space technology. Then it introduces the theoretical framework of THz atmospheric propagation, including some fundamental physical concepts and processes. The attenuation effect (especially the absorption of water vapor), the scattering of aerosol particles and the effect of turbulent flow mainly influence THz atmosphere propagation. Fundamental physical laws are illuminated as well, such as Lamber-beer law, Mie scattering theory and radiative transfer equation. The last part comprises the demonstration and comparison of THz atmosphere propagation models like Moliere(V5), SARTre and AMATERASU. The essential problems are the deep analysis of physical mechanism of this process, the construction of atmospheric propagation model and databases of every kind of material in the atmosphere, and the standardization of measurement procedures.

  13. Department of Plasma Physics and Technology - Overview

    International Nuclear Information System (INIS)

    Full text: The activities of the Department in 2007 continued previous studies in the following fields of plasma physics, controlled nuclear fusion and plasma technology of surface engineering: · Studies of physical phenomena in pulsed discharges in the Plasma-Focus (PF) and RPI-IBIS facilities; · Development of selected methods for high-temperature plasma diagnostics; · Research on plasma technologies; · Selected problems of plasma theory and computational modelling. As for the experimental studies particular attention was paid to the analysis of the correlation of X-ray pulses with pulsed electron beams and other corpuscular emissions from different Plasma-Focus (PF) facilities. A collisional-radiative model, taking into account the Stark effect and strong electric fields in the so called '' hot- spot '' regions of a pinch, was applied in those analyses. The main aim of these studies was to identify the physical phenomena responsible for the emission during the PF-type discharges. The emitted protons were also measured with nuclear track detectors. The measurements made it possible to obtain images of the regions, where the D-D fusion reactions occurred, as well as to determine the angular distribution of the emitted protons. Pulsed plasma streams were also investigated by means of time-resolved optical spectroscopy and corpuscular diagnostics. In a frame of the EURATOM program, efforts were devoted to the development of diagnostic methods for tokamak-type facilities. Such studies include the design and construction of the 4-channel Cherenkov-type detection system for the TORE-SUPRA tokamak at CEA-Cadarache. In the meantime in order to collect some experience a new measuring head was especially prepared for experiments within small facilities. Other fusion- oriented efforts are connected with the application of the solid-state nuclear track detectors for investigation of protons from tokamak plasma and high-energy beams emitted from laser produced plasmas

  14. Chemico-physical models of cometary atmospheres

    International Nuclear Information System (INIS)

    Sublimation (vaporization) of the icy component of a cometary nucleus determines the initial composition of the coma gas as it streams outward and escapes. Photolytic reactions in the inner coma, escape of fast, light species such as atomic and molecular hydrogen, and solar wind interaction in the outer coma alter the chemical composition and the physical nature of the coma gas. Models that describe these interactions must include (1) chemical kinetics, (2) coma energy balance, (3) multifluid flow for the rapidly escaping light components, the heavier bulk fluid, and the plasma with separate temperatures for electrons and the remainder of the gas, (4) transition from a collision dominated inner region to free molecular flow of neutrals in the outer region, (5) pickup of cometary ions by the solar wind, (6) counter and cross streaming of neutrals with respect to the plasma which outside of the contact surface also contains solar wind ions, and (7) magnetic fields carried by the solar wind. Progress on such models is described and results including velocity, temperature, and number density profiles for important chemical species are presented and compared with observations

    Full text: The work of Department P-10 in 2004 included the following subjects: - development of radiographic 4 MeV electron accelerator, - physical and technological problems related to the development of accelerating and deflecting types travelling and standing wave RF structures and their subsystems, - MC simulations applied to radiotherapy; continuation study of photon beams with the use of BEAMnrc Monte Carlo codes, - minor works concerning the C-30 cyclotron: the modifications of an H- external ion source and actualisation our list for cyclotron upgrading. The compact 6 MeV electron linac constructed in Department P-10 was mounted on an experimental stand, equipped with necessary auxiliary systems (pulsed high power RF supply, focusing and beam measuring system, cooling and temperature stabilising and safety system) and put into preliminary operation. The output energy and current intensity of the structure were measured and compared with the calculated values. The computational codes written in our Department during realisation of the 6/15 MeV project were used for that purpose, giving satisfactory agreement of calculations with measurements. The accelerator can be operated in electron or X-ray mode depending on demand. In 2004 all sub-units of the accelerator were operationally tested and intensity optimisation for e-/X-ray conversion was made. As the linac is thought primarily as a tool for radiographic services which may be offered by the Department, a number of X-ray exposures to radiographic films has been made in order to check its usability and the quality of pictures. The MC calculations of photon beams produced on the e-/X converter were made to complete the design of radiographic facility. Apart from radiography, the output beams of electrons and/or X-rays can also be used for studies in dosimetry, radiation effects in electronic components, neutron production in RT low energy linacs and so on.

    The activities of P-10 Department in year 2005 were devoted to: - development of radiographic 4 MeV electron accelerator, - development of accelerating and deflecting types travelling (TW) and standing wave (SW) RF structures for electrons and ions, - MC simulations applied to photon and ion radiotherapy The compact 6 MeV electron linac constructed in Department P-10 was put in the beginning of reported year into experimental operation. The request for permission to use ionisation source (6 MeV linac) was submitted to National Atomic Energy Agency. On the basis of all necessary documents the permission for routine using of our linac was granted. Actually the e/X conversion tungsten target has been moved from vacuum to air. To improve the safety of accelerator operation, the new collimator and some shielding walls were added. Two regimes of operation are actually possible: X ray output beam or electron beam depending on user demand. Some old non-reliable sub-units of accelerator were replaced, and energy and intensity optimisation for e-/X-ray conversion were made. The MC calculations of photon beams produced on e-/X converter were repeated taking into account the new collimator and additional shields. The triode gun, originally thought of as a part of 6/15 MeV medical accelerator is still on long term tests showing excellent performance; it was twice opened to air to confirm the possibility of repeated formation of gun dispenser cathode. New pulse modulator was routinely used in these tests. The sublimation set-up designed and made in our Department for the TiN coating of accelerator components underwent successfully the technological test including coating quality of several ceramic RF power vacuum windows. Within the German heavy ion therapy program the DKFZ Heidelberg is responsible for medical physics problems of treatment planning and modeling of ion beams for GSI Radiotherapy Facility. The MC simulations are used to calibrate the X-ray CT scanners to obtain

Three experimental set-ups for electron and photon beam diagnostics are in course of installation and running -at: 4-5 MeV, 10-15 MeV, and 20 MeV. The 20 MeV unit will also be used for generation and metrology of narrow photon beams applicable in stereotactic radiosurgery. Preliminary design works are advanced, oriented, undertaken on an important project - high-power electron accelerators for radiation technology (10 MeV, 20-50 kW). Financial support for this task is still pending. A substantial part of the Department`s activity was oriented to an international collaboration with accelerator physics centres. Two works completed in 1997 were extended in 1998: microwave pulsed generator destined for short beam bunches diagnostics was installed and put in operation at INFN-Frascati; 27 pieces of polarized ``door-knob`` r.f. couplers for superconducting cavities in HERA ring were installed and put in operation. In the course of 1998 we got the message from DESY, that couplers are working well and brought desirable improvement in operation reliability. The new item of collaboration with DESY, is design, construction and r.f. measurements of a copper model of accelerating ``superstructure`` for TESLA collider. If successful, the use of niobium ``superstructure`` can shorten by about a few kilometres the length of the TESLA linear accelerator. First four 1 m sections of model structures were sent to DESY at the end of 1998. The next four are in preparation.

    In 2005 research activities in Department P-V were concentrated on the continuation of previous studies in the field of plasma physics and CNF, but new investigations were also undertaken, particularly in the field of plasma technology. The main tasks were as follows: 1. Studies of physical phenomena in pulsed discharges producing dense magnetized plasma; 2. Development of methods and tools for high-temperature plasma diagnostics; 3. Research in the field of plasma technologies. As to the first task, particular attention was paid to studies of X-ray pulses and pulsed electron beams, by means of different diagnostic techniques. Measurements of the polarization of the selected X-ray spectral lines and their correlation with pulsed e-beams were performed in the MAJA-PF facility. Taking into account microscopic irreproducibility of so-called 'hot-spots', particular efforts were devoted to the correlation of the X-ray emission from a single hot-spot with corresponding non-thermal electron pulses. Some observations of X-rays were performed also at the PF-1000 facility at IPPLM in Warsaw. Other studies concerned the correlation of fast-neutron pulses with X-rays and other corpuscular emissions. Results of experimental studies carried out in the IPJ-IPPLM collaboration were analyzed and summarized. New measurements, carried out in the MAJA-PF facility, determined the temporal correlation of X-rays pulses, fusion-neutrons, fast electron beams and high-energy ion beams. Other efforts concerned studies of fast (ripple-born) electrons in tokamaks. An analysis of the capability of special Cerenkov-type detectors (based on diamond-crystal radiators) was performed, and measuring heads for the CASTOR and TORE-SUPRA facilities have been designed. Concerning the development of plasma diagnostic techniques, characteristics of PM-355 nuclear track detectors were analyzed and the calibrated detectors (with appropriate absorption filters) were used for measurements of fast (> 3 Me

    International Nuclear Information System (INIS)

    In response to a request from the Department of Energy's (DOE) Office of Health and Environmental Research (OHER), the Committee on Atmospheric Chemistry has reviewed OHER's Atmospheric Chemistry Program (ACP). This report contains the committee's evaluation and critique arising from that review. The review process included a two-day symposium held at the National Academy of Sciences on September 25 and 26, 1990, that focused on presenting the ACP's current components, recent scientific accomplishments, and scientific plans. Following the symposium, committee members met in a one-day executive session to formulate and outline this report. In undertaking this review, OHER and ACP management requested that the committee attempt to answer several specific questions involving the program's technical capability and productivity, its leadership and organization, and its future direction. These questions are given in the Appendix. This report represents the committee's response to the questions posed in the Appendix. Chapter I explores the committee's view of the role that atmospheric chemistry could and should assume within the DOE and its prospective National Energy Strategy.

Ten dust samples, delivered by the University of Bremen (Germany) were analysed for the presence of 238Pu, 239+240Pu, 241Pu, 241Am and 244Cm. In 1999, the equipment of the Environmental Radioactivity Laboratory was enriched with a low- background liquid scintillator spectrometer (Wallac 1414-003 Guardian), which opened a whole new branch of possible work connected with determination of pure beta-emitters. First isotopes of interest were 90Sr and 241Pu accumulated in animal bones. For 90Sr measurements, an extensive library of scintillation quenching corrections was prepared. The spectrometer was also applied for tests of the purity of 32P for the Laboratory of Physical Chemistry. A new project on transfer of plutonium from forest soil and litter to fungi and plants has been started. It is a pilot study for a planned in-Lab experiment to be performed during the incoming year at the University of Extremadura, Caceres, Spain. Other projects conducted during 1999 in the Environmental Radioactivity Laboratory are described in short abstracts below. In the Laboratory of Physical Chemistry, the project on construction of the internal target assembly for isotope production was continued, in cooperation with the Institute's Division of Mechanical Construction and with the Cyclotron Section. At the same time, much investment was made into necessary renovations in the radiochemical laboratory. Research in the Laboratory was concentrated on preparation and evaluation of 32P sources for intravascular brachytherapy. With the help of the Institute's Health Physics Laboratory, liquid Na2H32PO4 sources were calibrated by TL dosimetry, and in cooperation with the Department of Nuclear Spectroscopy, some solid state sources containing 32P were prepared. Liquid 32P sources calibrated in the Institute were first applied in pre-clinical intravascular brachytherapy

The aim of electron accelerating structures is the search for electron accelerator miniaturization, especially for IORT accelerators. At higher frequencies, much higher accelerating fields can be applied and as the wavelength becomes shorter, the overall size of the structure and various components become smaller. Two RF frequency regions are investigated, the C-band region covering 4 to 8 GHz and X-band covering 8 to 12 GHz. In 2006, the main physical parameters of 5720 MHz SW side coupled structures were studied, as well as the availability of necessary microwave high power equipment. In 2007, further optimization of the accelerating structure was approached, the beam dynamics calculated and mechanical design of a prototype prepared. The prototype of a compact proton linac is under study and construction in ENEA-Frascati as an alternative to a cyclotron or synchrotron offered by specialized industries. Generally, linacs are characterized by the ease of beam extraction, and very good beam quality and simple energy changes. Compactness is achieved by very high operating RF frequency of 3 GHz. As a continuation of previous work, all manufacturing tests were finished and the documentation of subsection 2 was closed. In July 2007, the structure subsection 2 was completed and

    Members of the Education & Workforce Working Group and the American Institute of Physics (AIP) conducted the first ever National Demographic Survey of working professionals for the 2012 National Academy of Sciences Solar and Space Physics Decadal Survey to learn about the demographics of this sub-field of space science. The instrument contained questions for participants on: the type of workplace; basic demographic information regarding gender and minority status, educational pathways (discipline of undergrad degree, field of their PhD), how their undergraduate and graduate student researchers are funded, participation in NSF and NASA funded spaceflight missions and suborbital programs, and barriers to career advancement. Using contact data bases from AGU, the American Astronomical Society's Solar Physics Division (AAS-SPD), attendees of NOAA's Space Weather Week and proposal submissions to NSF's Atmospheric, Geospace Science Division, the AIP's Statistical Research Center cross correlated and culled these data bases resulting in 2776 unique email addresses of US based working professionals. The survey received 1305 responses (51%) and generated 125 pages of single space answers to a number of open-ended questions. This talk will summarize the highlights of this first-ever demographic survey including findings extracted from the open-ended responses regarding barriers to career advancement which showed significant gender differences.

  5. Highly physical penumbra solar radiation pressure modeling with atmospheric effects

    Robertson, Robert; Flury, Jakob; Bandikova, Tamara; Schilling, Manuel

    2015-10-01

    We present a new method for highly physical solar radiation pressure (SRP) modeling in Earth's penumbra. The fundamental geometry and approach mirrors past work, where the solar radiation field is modeled using a number of light rays, rather than treating the Sun as a single point source. However, we aim to clarify this approach, simplify its implementation, and model previously overlooked factors. The complex geometries involved in modeling penumbra solar radiation fields are described in a more intuitive and complete way to simplify implementation. Atmospheric effects are tabulated to significantly reduce computational cost. We present new, more efficient and accurate approaches to modeling atmospheric effects which allow us to consider the high spatial and temporal variability in lower atmospheric conditions. Modeled penumbra SRP accelerations for the Gravity Recovery and Climate Experiment (GRACE) satellites are compared to the sub-nm/s2 precision GRACE accelerometer data. Comparisons to accelerometer data and a traditional penumbra SRP model illustrate the improved accuracy which our methods provide. Sensitivity analyses illustrate the significance of various atmospheric parameters and modeled effects on penumbra SRP. While this model is more complex than a traditional penumbra SRP model, we demonstrate its utility and propose that a highly physical model which considers atmospheric effects should be the basis for any simplified approach to penumbra SRP modeling.

Another theoretical aim was an analysis of elementary atomic processes by means of quasi-classical models. Using methods of vector calculus, the mathematical model of binary collisions has been simplified. We also performed some new modelling of ion motion within and nearby the filamentary pinch column. Within the frame of experimental studies, we investigated the correlation of polarized X-rays and pulse streams of charged particles (electrons and ions) in the MAJA-PF device. A more detailed analysis of previous spectral measurements has been performed, and new experimental data about the polarization of X-ray lines have been collected. Results of ion measurements performed in collaboration with IFAS in Tandil (Argentina) have been elaborated. In the collaboration with INFIP in Buenos Aires (Argentina) plasma characteristics of the PROTO-1Z pulsed arc have been investigated and a new series of ion measurements within the IBISEK device have been performed. In the frame of the collaboration with IFPiLM in Warsaw, different experiments with the large PF-1000 facility were carried out, and particularly the

    The algorithm chosen to represent the advection in atmospheric models is often used as the primary attribute to classify the model. Meteorological models are generally classified as spectral or grid point, with the term grid point implying discretization using finite differences. These traditional approaches have a number of shortcomings that render them non-physical. That is, they provide approximate solutions to the conservation equations that do not obey the fundamental laws of physics. The most commonly discussed shortcomings are overshoots and undershoots which manifest themselves most overtly in the constituent continuity equation. For this reason many climate models have special algorithms to model water vapor advection. This talk focuses on the development of an atmospheric general circulation model which uses a consistent physically-based advection algorithm in all aspects of the model formulation. The shallow-water model of Lin and Rood (QJRMS, 1997) is generalized to three dimensions and combined with the physics parameterizations of NCAR's Community Climate Model. The scientific motivation for the development is to increase the integrity of the underlying fluid dynamics so that the physics terms can be more effectively isolated, examined, and improved. The expected benefits of the new model are discussed and results from the initial integrations will be presented.

    Full text: The activity of the P-10 department is focused on the development of new acceleration techniques and technology, as well as on applications of particle accelerators. Our team is able to perform all kind of calculations of research, medical and industrial accelerator components, including accelerating cavities, magnets, transfer lines, sources and targets, collimators and applicators. The main topic of the 2010 was the realization of the ' Accelerators and Detectors ' project. All results of this work are included in detailed descriptions of the particular machines. The other tasks are summarized below: 1) WP-06 Task in the European XFEL Project As part of the EXFEL preparatory phase, IPJ is developing HOM and Pickup output lines from superconducting cavities antennas, and Beam Line Absorbers of travelling HOM. This abridged WP-06 task is wholly realized by IPJ and belongs to WPG-1 (Work Package Group 1- Cold linac). The HOM couplers are used to extract and to dissipate Radio Frequency ('' RF '') energy present in the cavity due to the excitation of the HOMs by the electron beam bunches. The low frequency part of the HOM spectrum (below the cut-off frequency of the beam tube) will be extracted by HOM couplers and transmitted via coax lines to external loads. Each 9-cell cavity is equipped with two HOM couplers placed close to the end cells and working in a 2K environment. The propagating HOM power will be ca. 5.4 W/cryomodule for operation with 40000 bunches/s of a nominal charge of 1 nCoulomb. Power dissipated in BLA will be transferred to the 70 K environment by a copper stub brazed directly to the absorbing ceramic ring. The stub holds the ring in a stainless steel vacuum chamber thermally isolated from the 2K region by a flexible bellows. In 2010 the wakefields excited by beam bunches down to 40 microns were calculated, and the related wake potential and frequency spectrum of HOMs evaluated.

    Full text:Due to financial shortages, the Extensive Research Program ''Isotopes and Accelerators'' did not come into effect. This in consequence limited the scope of new design and construction works. As the most important topic remained the continuation of work on Ordered Project for new therapeutical accelerator ''6/15''. It has to be emphasized that during realization of this task, several significant modifications were introduced to get a final solution better matched to future implementation of the prototype. The initially adopted ''classical'' solution of accelerating structure with separate bunching and accelerating sections, was replaced by a single mechanical unit with both incorporated functional subsystems. This solution is more convenient for future production and servicing, but in order to cover the broad range of energy variation is was necessary to recalculate the beam dynamics and to find the method for internal phase correction. Another important feature was an additional design of two possible injection systems, the first with a diode gun for 40 keV energy, and the second one with triode gun 15-20 keV. These solutions provide a contingency for - two production versions of an accelerator equipped with different RF power systems - klystron or magnetron. Substantial effort was directed to completion and operation of an experimental facility for testing accelerating structures. This facility is equipped with a RF high - power source in the form of 6 MW klystron, and high-vacuum pumping system. External apparatus connected to the facility are - magnetic spectrometer and computerized water phantom, which enable the diagnostics of accelerated electron beam. Several structure models were tested, and for the first time an electron energy in the vicinity of 15 MeV was registered. Other important subjects in (he Department's activity were: * Implementation of new versions of MC codes, for analysis of electron and photon beams distribution at the output of

    A number of methods have been proposed for the atmospheric correction of the multispectral satellite images, based on either atmosphere modelling or images themselves. Full radiative transfer models require a lot of ancillary information about the atmospheric conditions at the acquisition time. Whereas, image based methods cannot account for all the involved phenomena. Therefore, the aim of this paper is the comparison of different atmospheric correction methods for multispectral satellite images. The experimentation was carried out on a study area located in the catchment area of Yialias river, 20 km South of Nicosia, the Cyprus capital. The following models were tested, both empirical and physically based: Dark object subtraction, QUAC, Empirical line, 6SV, and FLAASH. They were applied on a Landsat 8 multispectral image. The spectral signatures of ten different land cover types were measured during a field campaign in 2013 and 15 samples were collected for laboratory measurements in a second campaign in 2014. GER 1500 spectroradiometer was used; this instrument can record electromagnetic radiation from 350 up to 1050 nm, includes 512 different channels and each channel covers about 1.5 nm. The spectral signatures measured were used to simulate the reflectance values for the multispectral sensor bands by applying relative spectral response filters. These data were considered as ground truth to assess the accuracy of the different image correction models. Results do not allow to establish which method is the most accurate. The physics-based methods describe better the shape of the signatures, whereas the image-based models perform better regarding the overall albedo.

    Full text: The principal Department's duties in 1999 have not changed and were consequently directed on development in the area of electron and ion accelerators and their applications in science, medicine and technology. Two important events dominated the current and future orientation of R and D activity. The first was finalizing of long time efforts for preparing of the ordered research project granted by the State Committee of Scientific Research and devoted to elaboration and design of a new electron accelerator for radiotherapy, with two energies of X-ray photon beams. This project was formally approved in March 1999 and due to organisatory procedures set in operation after few months. In the second half of 1999, an important progress was done in advancing the project. The second mentioned event is foundation by the government of a Multiyear Research Programme - called ''Isotopes and Accelerators''. This programme formulates a broad spectrum of important tasks oriented on application of isotopes and accelerator techniques in many branches of science and national economy. The expected participation of the Department in this programme comprises following subjects: medical interoperative accelerator, high power electron accelerator for radiation technology, and upgrading of cyclotron for isotopes production. In course of 1999, preparatory studies in these subjects were carried out. Some of the results were presented on conferences and seminars. An interesting experience was the expertise done on technical status of Eindhoven isochronous cyclotron and its possible transfer to Swierk as a professional tool for isotopes production. In the group of medical applications, three subjects were continued during 1999 and brought important results: - completion of microwave measurements of high gradient acceleration structure for low energy accelerators; such structure will be very useful solution for Co-Line and interoperative accelerator; - evaluation of design data and

    Significant advances in our theoretical basis for understanding several physical processes related to dynamical phenomena on the sun were achieved. We have advanced a new model for spicules and fibrils. We have provided a simple physical view of resonance absorption of MHD surface waves; this allowed an approximate mathematical procedure for obtaining a wealth of new analytical results which we applied to coronal heating and p-mode absorption at magnetic regions. We provided the first comprehensive models for the heating and acceleration of the transition region, corona, and solar wind. We provided a new view of viscosity under coronal conditions. We provided new insights into Alfven wave propagation in the solar atmosphere. And recently we have begun work in a new direction: parametric instabilities of Alfven waves.

    (full text) In the context of general discussions concerning the activity of the Institute, it was important to look critically at current and future directions at the Department's activity. Attention is given to development of basic accelerator knowledge, realized at home and throughout international collaborations. Of importance is a steady improvement of metrological and experimental basis for accelerator research. Apart of this, some development tendencies were formulated during 1997, oriented to application fields of accelerators. As examples should be named: - medical applications: a) A serious effort was given to an idea of using the existing compact cyclotron C-30 as a source for creation of a diagnostic centre in Swierk. The proposition was formulated in contact with the Nuclear Medicine Department of the Medical Academy, and the ''Brodno'' General Hospital. In spite of declared medical interest in such an installation, the project was not approved, due to lack of proper financial support. b) Model measurements and verification of theoretical assumptions and calculations oriented on the design of a very short, high-gradiented acceleration structure for the low energy accelerator COLINE/1000 were done. This project will enable us to achieve ''source - isocentre distance'', of 1000 mm, instead of existing 800 mm. This is important for therapy. In 1998, this work will be supported by the State Committee for Scientific Research. c) Preliminary discussions, and design approach were undertaken in collaboration with the Centre of Oncology, for elaboration of a movable low-energy accelerator with electron beam output, matched to inter operational irradiation during surgical therapy of tumours. - applications in radiation technology: Comparison of isotope and machine radiation sources indicates that, under Polish conditions it is reasonable to use purpose-oriented high power accelerators.

    (full text) In 1997, theoretical studies mainly concerned the verification of physical models on the basis of experimental data, an analysis of plasma behaviour within regions close to electrode surfaces during quasi-continuous discharges induced by microwaves , as well as modelling of a discharge development within coaxial plasma injectors. Another direction of theoretical studies concerned elementary processes of importance for plasma research, and in particular those taking into consideration the role of spin within a classical model of proton - hydrogen atom collisions. Experimental studies comprised measurements of pulsed electron beams and effects of the polarization of X-rays emitted from Plasma Focus (PF) facilities, research on emission characteristics of different PF devices, as well as measurements of pulsed electron and ion-beams emitted from various devices of the PF and Z-Pinch type. An important direction of experimental studies concerned X-ray and ion measurements at a large PF-1000 facility. In the field of plasma diagnostics, efforts were devoted to an analysis of the results obtained from time-resolved measurements of nitrogen ions and deuterons within PF-type devices. Within a frame of diagnostics, a substantial achievement was also the design and construction of a new measuring equipment for studies of plasma dynamics and X-ray emissions. Particular attention was also paid to studies connected with the calibration of various solid-state nuclear track detectors (NTDs), particularly modern plastic detectors of the CR-39, PM-355 and PM-500 type. Studies in the field of fusion technology concerned the design and construction of a special pulse generator for the simulation of electromagnetic interference, as well as other efforts connected with research on electromagnetic compatibility of electronic and electrotechnical devices. Research on new types of HV pulse generators were carried out partially under contracts with industrial laboratories. In

    International Nuclear Information System (INIS)

    Bringing up the young people who are seen as the guaranty of the future depends on a better education. One of the best ways of forming a high in quality education is connected to developing the quality in teacher training. Most of the developed countries have been carrying on studies in order to develop teacher training. School experience classes are the ones which are planned for the candidate teachers to observe the school in learning and teaching period and to practice in classrooms. Beginning from candidate teachers first years at school, this class should be thought to be beneficial for identifying their future school atmosphere, and it should be run effectively. For this purpose, it has been identified what difficulties the physics undergraduate and physics (with no thesis) master students, who took part in School Experience classes at the practice schools of Konya at which faculty-school cooperation is applied, had during activities, and their success at overcoming these difficulties, and their ideas about the practice school and its teachers. The research was done by making a survey to the physics undergraduate and physics(with no thesis) master students in 2003 Spring semester. The results of the research were analyzed for both girls and boys separately. After analyzed, the results showed that the most striking activity which both the undergraduate physics and physics(with no thesis) master students had difficulty was group activities. Moreover, it showed that 90 percent of the two groups had the idea that school experience activities would be beneficial for being a good physics teacher. It has been also recognized that the physics undergraduate students had a more positive view than physics(with no thesis) master students on the matter of meeting lack of interest from practice teachers, and taking the same course from the same teacher

We are studying the heterogeneity of rock formations and also working on problems of the nuclear geophysics. In the greater part of this research methods of nuclear physics are employed - neutrons as probing particles or radioactive and stable isotopes in tracer technologies. Concentrations of F-11, F-113 and CHCl3, CHCCl3, CCl4, F-12 and SF6 in Cracow atmosphere were measured by gas chromatography (GS). The five-point interpolation-procedure for calculations of week weight-averaged concentrations of the above-mentioned gases was developed. At the Kasprowy Wierch Station (Tatra Mts.) the measurement of greenhouse effect gases (CH4, CO2 and SF6) has been continued. A method for measuring the SF6 concentration in water as a hydrologic tracer was developed for determining the ages of young groundwater systems. Similar enrichment is being developed for such potential tracers as freon F-11 and F-12. Studies were continued on models for the interpretation of tracer data and transit time calculations in groundwater systems. Environmental tracer study of the Oligocene aquifer in the Mazovian basin has been completed. It has appeared that in the Late Glacial the recharge of groundwater systems in the Mazovian basin was, to a high degree, from paleolakes. Moderate concentrations of 4He excess showed that the glacial waters cannot be older than those recharged at the end stages of the Last Glacial.

  16. Physics and medical applications of cold atmospheric plasma

    Science.gov (United States)

    Keidar, Michael

    2013-09-01

    Recent progress in atmospheric plasmas led to the creation of cold plasmas with ion temperature close to room temperature. Varieties of novel plasma diagnostic techniques were applied in a quest to understand physics of cold plasmas. In particular it was established that the streamer head charge is about 108 electrons, the electrical field in the head vicinity is about 107 V/m, and the electron density of the streamer column is about 1019 m3. We have demonstrated the efficacy of cold plasma in a pre-clinical model of various cancer types (lung, bladder, breast, head, neck, brain and skin). Both in-vitro andin-vivo studies revealed that cold plasmas selectively kill cancer cells. We showed that: (a) cold plasma application selectively eradicates cancer cells in vitro without damaging normal cells. (b) Significantly reduced tumor size in vivo. Cold plasma treatment led to tumor ablation with neighbouring tumors unaffected. These experiments were performed on more than 10 mice with the same outcome. We found that tumors of about 5mm in diameter were ablated after 2 min of single time plasma treatment. The two best known cold plasma effects, plasma-induced apoptosis and the decrease of cell migration velocity can have important implications in cancer treatment by localizing the affected area of the tissue and by decreasing metastasic development. In addition, cold plasma treatment has affected the cell cycle of cancer cells. In particular, cold plasmainduces a 2-fold increase in cells at the G2/M-checkpoint in both papilloma and carcinoma cells at ~24 hours after treatment, while normal epithelial cells (WTK) did not show significant differences. It was shown that reactive oxygen species metabolism and oxidative stress responsive genes are deregulated. We investigated the production of reactive oxygen species (ROS) with cold plasma treatment as a potential mechanism for the tumor ablation observed.

  17. Dynamics of atmosphere and physics of open systems

    International Nuclear Information System (INIS)

    Way of creation and development of modern evolutionary models of an atmosphere of the Earth are analyzed. It is shown, that constructions of such models are impossible without use of the theory of open systems as a coming stream of solar radiation determines the structure of an atmosphere. The basic difficulties in the theory of open systems are submitted from which the problem of irreversibility is main. Results of the analysis of atmospheres non-equilibrium role in a spectrum of its own fluctuations are resulted. The analysis bases on the equations of nonequilibrium thermodynamics. These results in particular testify to strong dependence of a spectrum of fluctuations of an atmosphere on character of interaction of atmospheric gas with a stream of solar radiation. (author)

    Full text: The Department is engaged in research on: Tracer hydrology, Study of the gases responsible for greenhouse effects, Slow-neutron transport in materials, Radon research, Semi-empirical calibration procedures for neutron borehole probes, Application of artificial neural networks in geophysical parameters determination, Neutron and particle transport studies for accelerator shielding and measurement gauges. Studies were continued on models for the interpretation of tracer data and transit time calculations in hydrologic systems and on solute velocities and hydraulic parameters in Karstic Aquifers. At the Kasprowy Wierch Station (Tatra Mountains) were continued the measurements of gases participating in the greenhouse effect (CH4, CO2 and SF6). The same gases are also measured in Cracow. The data obtained during the last two years will make possible an exhaustive study of the balance of greenhouse gases. The use of SF6 as tracer substance for studies of the age of subterranean waters was studied. A method of measuring the concentration of SF6 in subterranean waters was developed and tested on a few spring outlets. The problem of generally valid approximation describing scattering of slow neutrons on hydrogenous mixtures was finalized and published in Nuclear Instruments and Methods A. Also a theoretical method for calculating scattering and diffusion of thermal neutrons was worked out for plexiglass and published in Journal of Physics D. Long term measurements of radon concentration were continued. A simple method for measuring radon concentration in soil gas using track-etch detectors was tested and compared with measurements performed with ionization chamber ALPHAGuard PQ 2000. For the purpose of collecting the soil gas a special probe has been designed which stops the inflow of atmospheric air into the hole. The results were presented at the Int. Conference on Nuclear Tracks in Solids held in Besancon (France) and will be published in Radiation

  20. Department of Environmental and Radiation Transport Physics - Overview

    International Nuclear Information System (INIS)

    The scientific activity of the Department in 2001 can be summarised as follows. In the Environmental Physics Laboratory gas chromatography methods are being developed mainly for atmospheric investigations and hydrological applications. A method for measuring the SF6 contents in water for determining the age of young groundwaters is well advanced. Reconnaissance measurements performed in two aquifers yielded a reasonable agreement with the ages obtained from the tritium method. A proper determination of trace gases dissolved in water requires the measurement of the so-called ''excess air'' resulting from the excessive dissolution of air bubbles at the groundwater table. For this purpose, a new method of analysing the concentrations of argon and neon in water was developed. The separation of argon from oxygen in gas samples, extracted from water, carried out with the help of the catalyst of NiO type. Neon is determined with the aid of a pulse discharge helium detector (type PI-2D, VALCO Ltd) doped with neon. The initial results are promising. Atmospheric investigations were continued by measurements of the concentrations of F-11, F-12, F-113, CHCl3, CHCCl3, CCl4, and SF6 in the Cracow area. Incidentally, high concentrations of SF6 are observed. The air flow trajectories available in the BADC Trajectory Service (http://cirrus.badc.rl.ac.uk/trajectory/) were used in an attempt to identify the emission source of these high SF6 concentrations. So far only the north-west direction was identified. Hydrogeological investigations of the origin and ages of different interesting groundwater systems by environmental isotope methods were also continued, and the origin of chemically unique mineral water in Krynica Spa has been identified as related to dehydration of clay minerals in burial diagenesis. The Natural Radioactivity Laboratory has been involved in interdisciplinary projects on the measurements of radon concentration in soil gas in areas of different geological

    1980-01-01

    The methanol/stainless steel vapor chambers (flat-plate heat pipes) discussed in this paper were developed for use in spaceborne atmospheric cloud chambers. This application imposed stringent thermal and mechanical requirements on the design. Flatness, low thermal mass, vibration, and structural integrity requirements were achieved in addition to precision temperature uniformity and thermal transport. Heat transfer coefficients on the order of 0.34 to 0.40 W/sq cm -C were measured. The vapor chambers are capable of transporting 170 W-cm per cm of width in either the axial or side-to-side direction.

  6. Cognitive-based approach in teaching 1st year Physics for Life Sciences, including Atmospheric Physics and Climate Change components

    Petelina, S. V.

    2009-12-01

    Most 1st year students who take the service course in Physics - Physics for Life Sciences - in Australia encounter numerous problems caused by such factors as no previous experience with this subject; general perception that Physics is hard and only very gifted people are able to understand it; lack of knowledge of elementary mathematics; difficulties encountered by lecturers in teaching university level Physics to a class of nearly 200 students with no prior experience, diverse and sometime disadvantageous backgrounds, different majoring areas, and different learning abilities. As a result, many students either drop, or fail the subject. In addition, many of those who pass develop a huge dislike towards Physics, consider the whole experience as time wasted, and spread this opinion among their peers and friends. The above issues were addressed by introducing numerous changes to the curriculum and modifying strategies and approaches in teaching Physics for Life Sciences. Instead of a conventional approach - teaching Physics from simple to complicated, topic after topic, the students were placed in the world of Physics in the same way as a newborn child is introduced to this world - everything is seen all the time and everywhere. That created a unique environment where a bigger picture and all details were always present and interrelated. Numerous concepts of classical and modern physics were discussed, compared, and interconnected all the time with “Light” being a key component. Our primary field of research is Atmospheric Physics, in particular studying the atmospheric composition and structure using various satellite and ground-based data. With this expertise and also inspired by an increasing importance of training a scientifically educated generation who understands the challenges of the modern society and responsibilities that come with wealth, a new section on environmental physics has been developed. It included atmospheric processes and the greenhouse

  7. Falsification Of The Atmospheric CO2 Greenhouse Effects Within The Frame Of Physics

    Gerlich, Gerhard

    2007-01-01

    The atmospheric greenhouse effect, an idea that authors trace back to the traditional works of Fourier 1824, Tyndall 1861 and Arrhenius 1896 and is still supported in global climatology essentially describes a fictitious mechanism in which a planetary atmosphere acts as a heat pump driven by an environment that is radiatively interacting with but radiatively equilibrated to the atmospheric system. According to the second law of thermodynamics such a planetary machine can never exist. Nevertheless, in almost all texts of global climatology and in a widespread secondary literature it is taken for granted that such mechanism is real and stands on a firm scientific foundation. In this paper the popular conjecture is analyzed and the underlying physical principles are clarified. By showing that (a) there are no common physical laws between the warming phenomenon in glass houses and the fictitious atmospheric greenhouse effects, (b) there are no calculations to determine an average surface temperature of a planet, ...

    2013-04-10

    The problem of simultaneous physical retrieval of surface emissivity, skin temperature, and temperature, water-vapor, and ozone atmospheric profiles from high-spectral-resolution observations in the infrared is formulated according to an inverse problem with multiple regularization parameters. A methodology has been set up, which seeks an effective solution to the inverse problem in a generalized L-curve criterion framework. The a priori information for the surface emissivity is obtained on the basis of laboratory data alone, and that for the atmospheric parameters by climatology or weather forecasts. To ensure that we deal with a problem of fewer unknowns than observations, the dimensionality of the emissivity is reduced through expansion in Fourier series. The main objective of this study is to demonstrate the simultaneous retrieval of emissivity, skin temperature, and atmospheric parameters with a two-dimensional L-curve criterion. The procedure has been demonstrated with spectra observed from the infrared atmospheric sounder interferometer, flying onboard the European Meteorological Operational satellite. To check the quality and reliability of the methodology, we have used spectra recorded over regions characterized by known or stable emissivity. These include sea surface, for which effective emissivity models are known, and arid lands (Sahara and Namib Deserts) that are known to exhibit the characteristic spectral signature of quartz-rich sand.

    2005-03-01

    The education and training of the workforce needed to assure global competitiveness of American industry in high technology areas, along with the proper role of various disciplines in that educational process, is currently being re-examined. Several academic areas in science and engineering have reported results from such studies that revealed several broad themes of educational need that span and cross the boundaries of science and engineering. They included greater attention to and the development of team-building skills, personal or interactive skills, creative ability, and a business or entrepreneurial where-with-all. We will report in this paper the results of a fall 2000 Department of Education FIPSE grant to implement changes in its graduate physics program to address these issues. The proposal goal was to produce next-generation physics graduate students that are trained to evaluate and overcome complex technical problems by their participation in courses emphasizing the commercialization of technology research. To produce next-generation physics graduates who have learned to work with their student colleagues for their mutual success in an industrial-like group setting. And finally, to produce graduates who can lead interdisciplinary groups in solving complex problems in their career field.

  16. Variational iteration solving method for El Nino phenomenon atmospheric physics of nonlinear model

    Institute of Scientific and Technical Information of China (English)

    2005-01-01

    A class of El Nino atmospheric physics oscillation model is considered. The El Nino atmospheric physics oscillation is an abnormal phenomenon involved in the tropical Pacific ocean-atmosphere interactions. The conceptual oscillator model should consider the variations of both the eastern and westem Pacific anomaly patterns. An El Nino atmospheric physics model is proposed using a method for the variational iteration theory. Using the variational iteration method, the approximate expansions of the solution of corresponding problem are constructed. That is, firstly, introducing a set of functional and accounting their variationals, the Lagrange multiplicators are counted, and then the variational iteration is defined, finally, the approximate solution is obtained. From approximate expansions of the solution, the zonal sea surface temperature anomaly in the equatorial eastern Pacific and the thermocline depth anomaly of the seaair oscillation for El Nino atmospheric physics model can be analyzed. El Nino is a very complicated natural phenomenon. Hence basic models need to be reduced for the sea-air oscillator and are solved. The variational iteration is a simple and valid approximate method.

    2009-03-01

    The Department of Energy's Atmospheric Science Program (ASP) conducts research pertinent to radiative forcing of climate change by atmospheric aerosols. The program consists of approximately 40 highly interactive peer-reviewed research projects that examine aerosol properties and processes and the evolution of aerosols in the atmosphere. Principal components of the program are instrument development, laboratory experiments, field studies, theoretical investigations, and modeling. The objectives of the Program are to 1) improve the understanding of aerosol processes associated with light scattering and absorption properties and interactions with clouds that affect Earth's radiative balance and to 2) develop model-based representations of these processes that enable the effects of aerosols on Earth's climate system to be properly represented in global-scale numerical climate models. Although only a few of the research projects within ASP are explicitly identified as primarily modeling activities, modeling actually comprises a substantial component of a large fraction of ASP research projects. This document describes the modeling activities within the Program as a whole, the objectives and intended outcomes of these activities, and the linkages among the several modeling components and with global-scale modeling activities conducted under the support of the Department of Energy's Climate Sciences Program and other aerosol and climate research programs.

    Placing numerical scores on research by UK universities has always been a controversial task, and the new system of "quality profiles" used to evaluate departments in the 2008 Research Assessment Exercise (RAE) should keep number-crunchers busy through 2009. While previous RAEs ranked departments using single numbers on a seven-point scale, the 2008 exercise instead lists the percentage of research activity rated at each of five levels, from a "world-leading" 4* to an unclassified "below standard".

  19. Verification study of a three-dimensional local scale atmospheric model PHYSIC at seacoast region

    International Nuclear Information System (INIS)

    The performance of a three-dimensional numerical atmospheric model (PHYSIC) was examined over a seacoast region with the data observed during the field tracer experiment at the Tokai site. The main frame of PHYSIC is made up of the momentum equations with the hydrostatic and Boussinesq approximation, the second-order turbulence closure model level 2.5 by Yamada and other basic equations of physical processes in the atmosphere. A terrain following Z* coordinate system is used. The present model successfully predicts the temporal change of wind field within twenty hours from the evening to the next noon. The occurrence and structure of sea breeze are simulated satisfactorily. The model performance concerning the eddy diffusivities is thought to be reasonable, although the direct comparison between the calculation and observation is restricted to the wind and temperature profiles by the limited observation data. This was supported by an additional calculation with a diagnostic model of turbulence quantities. (author)

    The American Association of Physics Teacher's Physics Teaching Resource Agents (AAPT/PTRA) program has a twenty year history of providing professional development for in-service pre-college physics and physical science teachers. More than 500 teachers have been prepared through NSF-funded summer institutes to provide professional development for their peers in a wide variety of venues ranging from urban, inner-city classrooms to classrooms in low population rural areas. A wide variety of inquiry-based, active engagement workshops have been developed that can assist in-service teachers at all experience and preparation levels, from new and crossover teachers to those who have taught for many years. AAPT/PTRA presenters are typically active physics teachers who share lessons learned in their classrooms on how to adopt research-based practices. College and university physics and astronomy departments interested in providing in-service professional development for pre-college teachers in their geographic areas can enter into agreement with the AAPT/PTRA program to utilize the services of these trained professional development providers. United States Department of Education Math and Science Partnership funds that are allocated to each state are an excellent source of funds that physics and astronomy departments can use to support this type of professional development for physics and physical science teachers. An example of a funded program currently in place in Texas will be presented. AAPT/PTRA program is currently funded by NSF grant # ESI-0138617.

    International Nuclear Information System (INIS)

    The principal activities in the fields of solid-state physics (neutron scattering), plasma physics and meteorology are presented in this report that covers the period 1 January to 31 December 1976. In addition, research on nuclear spectroscopy was carried out up until March 31, 1976. The experimental and theoretical work in solid-state physics is roughly divided into the following main subject fields: investigations of the dynamic and static properties of magnetic and superconducting solids; studies of various kinds of phase transitions in magnetic and molecular systems; and investigations of the dynamic and static properties of molecular crystals and adsorbed monolayers. The main object of basic research in plasma physics is to investigate waves and instabilities in a relatively cold steady state plasma (produced in a Q-machine). Turbulence, ion cyclotron waves, and ion-acoustic waves in the presence of electron plasma waves are the chief phenomena investigated. Work on nuclear spectroscopy was concentrated on problems relating to fission. The meteorology section is primarily engaged in studies of the planetary boundary layer. (B.R.H.)

    The project is focusing on the formation and growth mechanisms of atmospheric aerosol and cloud droplets. Both aerosol particles and cloud droplets affect strongly on the atmospheric radiation fluxes by scattering and absorption. The droplet formation results from physical and chemical processes occurring simultaneously. The studies concerning the tropospheric cloud droplet formation, laboratory experiments with a cloud chamber and stratospheric cloud formation are summarized. The recent studies summarized in this presentation indicate that both aerosol particles and cloud droplets have a significant role in climatic change and ozone depletion problems. The anthropogenic emissions of gaseous and particulate pollutants change the properties of atmospheric aerosols and cloud droplets. The research in this field will be continued and more quantitative understanding based both experimental and theoretical studies is required

    This volume presents numerical methods to solve soil physics problems using computers. It starts with the theory and then shows how to use Python code to solve the problems. Most soil physics books focus on deriving rather than solving the differential equations for mass and energy transport in the soil-plant-atmosphere continuum. The focus of this book is on solutions. Agricultural and biological scientists usually have a good working knowledge of algebra and calculus, but not of differential equations. Here numerical procedures are used to solve differential equations.

  7. Atmospheric corrosion monitoring at the US Department of Energy's Oak Ridge K-25 Site

    International Nuclear Information System (INIS)

    Depleted uranium hexafluoride (UF6) at the US Department of Energy's K-25 Site at Oak Ridge, TN has been stored in large steel cylinders which have undergone significant atmospheric corrosion damage over the last 35 years. A detailed experimental program to characterize and monitor the corrosion damage was initiated in 1992. Large amounts of corrosion scale and deep pits are found to cover cylinder surfaces. Ultrasonic wall thickness measurements have shown uniform corrosion losses up to 20 mils (0.5 mm) and pits up to 100 mils (2.5 mm) deep. Electrical resistance corrosion probes, time-of-wetness sensors and thermocouples have been attached to cylinder bodies. Atmospheric conditions are monitored using rain gauges, relative humidity sensors and thermocouples. Long-term (16 years) data are being obtained from mild steel corrosion coupons on test racks as well as attached directly to cylinder surfaces. Corrosion rates have been found to intimately related to the times-of-wetness, both tending to be higher on cylinder tops due to apparent sheltering effects. Data from the various tests are compared, discrepancies are discussed and a pattern of cylinder corrosion as a function of cylinder position and location is described

    Hollinden, A. B.; Eaton, L. R.

    1972-01-01

    A feasibility and concepts study for a zero-gravity (orbital) atmospheric cloud physics experiment laboratory is discussed. The primary objective was to define a set of cloud physics experiments which will benefit from the near zero-gravity environment of an orbiting spacecraft, identify merits of this environment relative to those of groundbased laboratory facilities, and identify conceptual approaches for the accomplishment of the experiments in an orbiting spacecraft. Solicitation, classification and review of cloud physics experiments for which the advantages of a near zero-gravity environment are evident are described. Identification of experiments for potential early flight opportunities is provided. Several significant accomplishments achieved during the course of this study are presented.

  14. Atmospheric inverse modeling with known physical bounds: an example from trace gas emissions

    Directory of Open Access Journals (Sweden)

    S. M. Miller

    2013-09-01

    Full Text Available Many inverse problems in the atmospheric sciences involve parameters with known physical constraints. Examples include non-negativity (e.g., emissions of some urban air pollutants or upward limits implied by reaction or solubility constants. However, probabilistic inverse modeling approaches based on Gaussian assumptions cannot incorporate such bounds and thus often produce unrealistic results. The atmospheric literature lacks consensus on the best means to overcome this problem, and existing atmospheric studies rely on a limited number of the possible methods with little examination of the relative merits of each. This paper investigates the applicability of several approaches to bounded inverse problems and is also the first application of Markov chain Monte Carlo (MCMC to estimation of atmospheric trace gas fluxes. The approaches discussed here are broadly applicable. A common method of data transformations is found to unrealistically skew estimates for the examined example application. The method of Lagrange multipliers and two MCMC methods yield more realistic and accurate results. In general, the examined MCMC approaches produce the most realistic result but can require substantial computational time. Lagrange multipliers offer an appealing alternative for large, computationally intensive problems when exact uncertainty bounds are less central to the analysis. A synthetic data inversion of US anthropogenic methane emissions illustrates the strengths and weaknesses of each approach.

  16. Determination of the Atmospheric Neutrino Flux and Searches for New Physics with AMANDA-II

    Energy Technology Data Exchange (ETDEWEB)

    IceCube Collaboration; Klein, Spencer; Collaboration, IceCube

    2009-06-02

    The AMANDA-II detector, operating since 2000 in the deep ice at the geographic South Pole, has accumulated a large sample of atmospheric muon neutrinos in the 100 GeV to 10 TeV energy range. The zenith angle and energy distribution of these events can be used to search for various phenomenological signatures of quantum gravity in the neutrino sector, such as violation of Lorentz invariance (VLI) or quantum decoherence (QD). Analyzing a set of 5511 candidate neutrino events collected during 1387 days of livetime from 2000 to 2006, we find no evidence for such effects and set upper limits on VLI and QD parameters using a maximum likelihood method. Given the absence of evidence for new flavor-changing physics, we use the same methodology to determine the conventional atmospheric muon neutrino flux above 100 GeV.

  17. Physical phenomena induced by passage of intense electromagnetic pulses (including CO2 lasers) through the atmosphere

    International Nuclear Information System (INIS)

    The electron fluid equations are combined with Maxwell's equations to investigate the physical phenomena that occurs when short, intense electromagnetic pulses (including the CO2 laser pulse) interact with the atmosphere. The phenomena of ''tailed erosion'' occurs when the pulse intensity exceeds the air-breakdown threshold. In some cases, the erosion of the pulse occurs first in the middle of the pulse and then occurs in the tail of the pulse. In addition, we discovered that the amount of the energy that a pulse carries through the atmosphere is independent of whether it is propagating vertically upward from the Earth's surface or vertically downward toward the Earth's surface, provided the distance the pulse travels is the same for both directions of the propagation. 20 refs., 9 figs

    start paying off as soon as the first beam becomes usable. Another aspect of general character which is worth mentioning is that both in 1980 and 1981 the series of nuclear physics workshops, started in 1978, continued with an enlarged audience and distinguished speakers. B. Bayman, S. Bjornholm, D.Mc. Hyder, M. Macfarlane and F. Stephens contributed with excellent talks. Within the program for cooperative research managed by the Argentine National Research Council and the U.S. National Science Foundation successful projects were carried out in collaboration with groups of Brookhaven, Ames and Tucson. Other joint efforts were also undertaken with scientists from Rio de Janeiro, Sao Paulo, Santiago de Chile, Tilbingen, Washington D.C., Grenoble, Berkeley, Paris, Strasbourg and local universities in Buenos Aires, La Plata and Tandil. The research output constitutes the main topic of this report and is summarized in the following pages. In general, the activity as a whole has steadily grown in spite of the fact that secondary (but necessary) chores have also multiplied and makes us feel frequently distressed. Adaptation to the new responsibilities ahead is the key. The years of running the old Synchrocyclotron and Cockcroft-Walton accelerator are finished. We now have a very powerful machine becoming operational, which will make possible experiments which up to now were only dreams. It will be our responsibility to make them become reality. It is both a sweet feeling and a heavy burden at the same time, to face this responsibility.

  19. Public Relations for Physics Departments: Convincing the Community that Quarks are Cool

    2002-03-01

    A strong public relations program can be of great importance to a physics department. Not only can effective PR improve the reputation of an individual department, but it can also serve the greater physics community by convincing the public that quarks, quantum dots, and nanostructures are cool. Building a solid reputation with the many constituents that a physics department serves can lead to greater media exposure, improved quality of student applicants, community and industrial partnerships, and even financial support. It isn’t difficult to create a strategic PR program, but it does take planning and commitment of resources. I will discuss the techniques and tactics of effective media, community, alumni, and internal relations, with special emphasis placed on establishing connections with media outlets, creating and publicizing outreach programs for the community, initiating a newsletter, organizing an external board of advisors, and developing an effective alumni relations program. The University of Arizona Physics Department serves as a case study, but other physics departments with similar communications programs will also be incorporated.

  20. Probing new physics with long-lived charged particles produced by atmospheric and astrophysical neutrinos

    International Nuclear Information System (INIS)

    As suggested by some extensions of the standard model of particle physics, dark matter may be a super-weakly-interacting lightest stable particle, while the next-to-lightest particle (NLP) is charged and metastable. One could test such a possibility with neutrino telescopes, by detecting the charged NLPs produced in high-energy neutrino collisions with Earth matter. We study the production of charged NLPs by both atmospheric and astrophysical neutrinos; only the latter, which is largely uncertain and has not been detected yet, was the focus of previous studies. We compute the resulting fluxes of the charged NLPs, compare those of different origins and analyze the dependence on the underlying particle physics set-up. We point out that, even if the astrophysical neutrino flux is very small, atmospheric neutrinos, especially those from the prompt decay of charmed mesons, may provide a detectable flux of NLP pairs at neutrino telescopes such as IceCube. We also comment on the flux of charged NLPs expected from proton–nucleon collisions and show that, for theoretically motivated and phenomenologically viable models, it is typically subdominant and below detectable rates

    Significant advances were made in the ability to model physical processes in the thermosphere (airglow and aurora) and middle atmosphere. These advances came in the form of code development and improved methods for updating input parameters (most notably, cross sections). Important advances were also made in the development of an algorithm for deducing O3 and O2 density profiles from full solar disk extinction measurements to be made by the instrument Solar Ultraviolet Spectral Irradiance Monitor (SUSIM) on board the upper atmosphere research satellite (UARS).

  8. Interactions between spacecraft motions and the atmospheric cloud physics laboratory experiments

    1981-01-01

    In evaluating the effects of spacecraft motions on atmospheric cloud physics laboratory (ACPL) experimentation, the motions of concern are those which will result in the movement of the fluid or cloud particles within the experiment chambers. Of the various vehicle motions and residual forces which can and will occur, three types appear most likely to damage the experimental results: non-steady rotations through a large angle, long-duration accelerations in a constant direction, and vibrations. During the ACPL ice crystal growth experiments, the crystals are suspended near the end of a long fiber (20 cm long by 200 micron diameter) of glass or similar material. Small vibrations of the supported end of the fiber could cause extensive motions of the ice crystal, if care is not taken to avoid this problem.

    Observation of the numerous thunderstorm ground enhancements (TGEs), i.e., enhanced fluxes of electrons, gamma rays, and neutrons detected by particle detectors located on the Earth's surface and related to the strong thunderstorms above it, helped to establish a new scientific topic—high-energy physics in the atmosphere. Relativistic runaway electron avalanches (RREAs) are believed to be a central engine initiating high-energy processes in thunderstorm atmospheres. RREAs observed on Mount Aragats in Armenia during the strongest thunderstorms and simultaneous measurements of TGE electron and gamma-ray energy spectra proved that RREAs are a robust and realistic mechanism for electron acceleration. TGE research facilitates investigations of the long-standing lightning initiation problem. For the last 5 years we were experimenting with the "beams" of "electron accelerators" operating in the thunderclouds above the Aragats research station. Thunderstorms are very frequent above Aragats, peaking in May-June, and almost all of them are accompanied with enhanced particle fluxes. The station is located on a plateau at an altitude 3200 asl near a large lake. Numerous particle detectors and field meters are located in three experimental halls as well as outdoors; the facilities are operated all year round. All relevant information is being gathered, including data on particle fluxes, fields, lightning occurrences, and meteorological conditions. By the example of the huge thunderstorm that took place at Mount Aragats on August 28, 2015, we show that simultaneous detection of all the relevant data allowed us to reveal the temporal pattern of the storm development and to investigate the atmospheric discharges and particle fluxes.

    2015-11-01

    The Flow Physics Facility (FPF) at UNH has test section dimensions W6.0m, H2.7m, L=72m. It can achieve high Reynolds number boundary layers, enabling turbulent boundary layer, wind energy and wind engineering research with exceptional spatial and temporal instrument resolution. We examined the FPF's ability to experimentally simulate different types of the atmospheric boundary layer (ABL): the stable, unstable, and neutral ABL. The neutral ABL is characterized by a zero potential temperature gradient, which is readily achieved in the FPF by operating when air and floor temperatures are close to equal. The stable and unstable ABLs have positive and negative vertical temperature gradients, respectively, which are more difficult to simulate without direct control of air or test section floor temperature. The test section floor is a 10 inch thick concrete cement slab and has significant thermal mass. When combined with the diurnal temperature variation of the ambient air, it is possible to achieve vertical temperature gradients in the test section, and produce weakly stable or weakly unstable boundary layer. Achievable Richardson numbers and Obukhov lengths are estimated. The different boundary layer profiles were measured, and compared to theoretical atmospheric models.

    In recent years a number of Arctic stations have installed micro-meteorological towers in recognition of the need to explicitly quantify the detailed exchanges between the surface and the atmosphere. One of the newer installations is a 20 meter tower in Tiksi, Russia that is located at 71.58N, 128.92E in the Russian Far East. The Tiksi tower is equipped with temperature, humidity and wind sensors at several levels (allowing the calculation of turbulent heat fluxes and fine scale characterization of the near-surface boundary layer) and H2O/CO2 sensors, It is located in near proximity to measurements of incoming and outgoing solar radiation (allowing energy balance calculations), and CH4 sensors, surface O3 measurements (allowing detection of ozone depletion events), and ancillary measurements of snow depth and permafrost active layer temperature profiles. An integrated analysis will look at the variability of these physical and chemical exchanges and variations over one annual cycle with an emphasis on detecting connections and linkages. This network of measurements supports the International Arctic Systems for Observing the Atmosphere (www.iasoa.org) and Global Cryosphere Watch (http://globalcryospherewatch.org/)

    Paleoclimate modelling is one of the core topics in the Past Global Changes project under the International Geosphere-Biosphere Programme and has received much attention worldwide in recent decades.Here we summarize the research on the Paleoclimate modeling, including the Holocene, Last Glacial Maximum, and pre-Quaternary climate intervals or events performed at the Institute of Atmospheric Physics under the Chinese Academy of Sciences (IAP/CAS) for over one decade. As an attempt to review these academic activities, we emphasize that vegetation and ocean feedbacks can amplify East Asian climate response to the Earth's orbital parameters and atmospheric CO2 concentration at the mid-Holocene. At the Last Glacial Maximum, additional cooling in interior China is caused by the feedback effects of East Asian vegetation and the ice sheet over the Tibetan Plateau, and the regional climate model RegCM2 generally reduces data-model discrepancies in East Asia. The simulated mid-Pliocene climate is characterized by warmer and drier conditions as well as significantly weakened summer and winter monsoon systems in interior China. On a tectonic timescale, both the Tibetan Plateau uplift and the Paratethys Sea retreat play important roles in the formation of East Asian monsoon-dominant environmental pattern during the Cenozoic.

    International Nuclear Information System (INIS)

    The Department of Atomic Physics at Plovdiv University has 40 year long experience in educating students in Atomic and Subatomic Physics. We aim at making the knowledge gained in nuclear physics part of the culture of our students. At the core of our educational activities lies our long and successful experience in studying the characteristics of atomic nuclei. In cooperation with JINR-Dubna we have studied the nuclei of approximately 40 percent of the periodic table elements. These studies also serve as a basis for the diverse implementation activities of the Department, which have an impressive geographical spread. In recent years our research has been focusing more specifically on radio-ecological issues with the valuable support of the Nuclear Regulatory Agency (NRA). Future more intense support on behalf of NRA's together with more dynamic links with other specialized units, such as the Kozloduy NPP in the first place, would considerably contribute to optimizing the effect of our overall activity.

  17. "SMART": A Compact and Handy FORTRAN Code for the Physics of Stellar Atmospheres

    Science.gov (United States)

    Sapar, A.; Poolamäe, R.

    2003-01-01

    A new computer code SMART (Spectra from Model Atmospheres by Radiative Transfer) for computing the stellar spectra, forming in plane-parallel atmospheres, has been compiled by us and A. Aret. To guarantee wide compatibility of the code with shell environment, we chose FORTRAN-77 as programming language and tried to confine ourselves to common part of its numerous versions both in WINDOWS and LINUX. SMART can be used for studies of several processes in stellar atmospheres. The current version of the programme is undergoing rapid changes due to our goal to elaborate a simple, handy and compact code. Instead of linearisation (being a mathematical method of recurrent approximations) we propose to use the physical evolutionary changes or in other words relaxation of quantum state populations rates from LTE to NLTE has been studied using small number of NLTE states. This computational scheme is essentially simpler and more compact than the linearisation. This relaxation scheme enables using instead of the Λ-iteration procedure a physically changing emissivity (or the source function) which incorporates in itself changing Menzel coefficients for NLTE quantum state populations. However, the light scattering on free electrons is in the terms of Feynman graphs a real second-order quantum process and cannot be reduced to consequent processes of absorption and emission as in the case of radiative transfer in spectral lines. With duly chosen input parameters the code SMART enables computing radiative acceleration to the matter of stellar atmosphere in turbulence clumps. This also enables to connect the model atmosphere in more detail with the problem of the stellar wind triggering. Another problem, which has been incorporated into the computer code SMART, is diffusion of chemical elements and their isotopes in the atmospheres of chemically peculiar (CP) stars due to usual radiative acceleration and the essential additional acceleration generated by the light-induced drift.

  18. The expanding world of physics at Manitoba : a hundred years of progress : Department of Physics and Astronomy, University of Manitoba

    International Nuclear Information System (INIS)

    The century covered by this book has seen scientific developments unprecedented in human history, so an endeavour has been made to describe something of the careers in physics of our departmental members past and present. The prologue tells of the lack of decisions, academic and governmental, which delayed until 1904 the arrival of the first university professors, who even then could be appointed only through a private benefaction. Chapters I-IV give the general development from 1904 to the present while Chapter V describes the work of the major groups in the department. A review of each group is followed by a brief selection of the work of the individual members. Few, if any, can hope to keep up with the many facets of the subject today, so a glimpse at what is going on at the cutting edge of the whole field may reveal something of the state of physics at the beginning of the twenty-first century. The final chapter (VI) tells of the department's service and outreach beyond the classroom and the honours and awards gained by the individual members.

  19. Minimally-Invasive Gene Transfection by Chemical and Physical Interaction of Atmospheric Pressure Plasma Flow

    2014-10-01

    Non-equilibrium atmospheric pressure plasma irradiated to the living-cell is investigated for medical applications such as gene transfection, which is expected to play an important role in molecular biology, gene therapy, and creation of induced pluripotent stem (iPS) cells. However, the conventional gene transfection using the plasma has some problems that the cell viability is low and the genes cannot be transferred into some specific lipid cells, which is attributed to the unknown mechanism of the gene transfection using the plasma. Therefore, the time-controlled atmospheric pressure plasma flow is generated and irradiated to the living-cell suspended solution for clarifying the transfection mechanism toward developing highly-efficient and minimally- invasive gene transfection system. In this experiment, fluorescent dye YOYO-1 is used as the simulated gene and LIVE/DEAD Stain is simultaneously used for cell viability assay. By the fluorescence image, the transfection efficiency is calculated as the ratio of the number of transferred and surviving cells to total cell count. It is clarified that the transfection efficiency is significantly increased by the short-time (plasma irradiation, and the high transfection efficiency of 53% is realized together with the high cell viability (>90%). This result indicates that the physical effects such as the electric field caused by the charged particles arriving at the surface of the cell membrane, and chemical effects associated with plasma-activated products in solution act synergistically to enhance the cell-membrane transport with low-damage.

  20. Subgrid-scale physical parameterization in atmospheric modeling: How can we make it consistent?

    Science.gov (United States)

    Yano, Jun-Ichi

    2016-07-01

    Approaches to subgrid-scale physical parameterization in atmospheric modeling are reviewed by taking turbulent combustion flow research as a point of reference. Three major general approaches are considered for its consistent development: moment, distribution density function (DDF), and mode decomposition. The moment expansion is a standard method for describing the subgrid-scale turbulent flows both in geophysics and engineering. The DDF (commonly called PDF) approach is intuitively appealing as it deals with a distribution of variables in subgrid scale in a more direct manner. Mode decomposition was originally applied by Aubry et al (1988 J. Fluid Mech. 192 115-73) in the context of wall boundary-layer turbulence. It is specifically designed to represent coherencies in compact manner by a low-dimensional dynamical system. Their original proposal adopts the proper orthogonal decomposition (empirical orthogonal functions) as their mode-decomposition basis. However, the methodology can easily be generalized into any decomposition basis. Among those, wavelet is a particularly attractive alternative. The mass-flux formulation that is currently adopted in the majority of atmospheric models for parameterizing convection can also be considered a special case of mode decomposition, adopting segmentally constant modes for the expansion basis. This perspective further identifies a very basic but also general geometrical constraint imposed on the massflux formulation: the segmentally-constant approximation. Mode decomposition can, furthermore, be understood by analogy with a Galerkin method in numerically modeling. This analogy suggests that the subgrid parameterization may be re-interpreted as a type of mesh-refinement in numerical modeling. A link between the subgrid parameterization and downscaling problems is also pointed out.

    How is water released in comets - directly from the nucleus versus sublimation from icy grains in the coma? How common and how prevalent are icy grains as a source of gas-phase water (and other volatiles) among the active comet population? These questions are being addressed through synergy between spatial-spectral studies of native volatiles in comets and the physical models tested against them. This synergy is extending the state-of-the-art in both domains. Ground-based near-IR spectroscopy (Keck, NASA IRTF, and ESO VLT) allowed measurements of spatially resolved inner coma temperatures and column densities for H2O - the most abundant volatile in the coma. These measurements motivated the inclusion of new physics in the models. The evolved models now open new questions and trigger improvement in the accuracy of measured temperature profiles, most recently extended to other molecules (HCN in the near-IR) and to other wavelength domains (CH3OH, through ALMA; S. Milam et al., this meeting). The net result is deeper quantitative insight into the competition among processes that cause heating and cooling of the coma and into the prevalent mechanism(s) for release of native volatiles in the gas phase.The same inner-coma modeling formalisms are used to interpret both the environment of Rosetta's mission target (67P/Churyumov-Gerasimenko) and those from the ground-based observations reported here (Combi et al. 2015, LPSC, #1714; Fougere et al., this meeting). While ground-based spectroscopy offers less detail than in-situ missions, it can probe the comae of many comets that may differ greatly from one another and from Rosetta's target, thereby assessing the extent to which the inner-coma environment of 67P is unique, and how it relates to other comets.We gratefully acknowledge support from NASA Planetary Atmospheres, Solar System Workings, Planetary Astronomy, and Astrobiology programs, and from NSF Astronomy and Astrophysics Research Grants program.

  17. Utilization of mesoscale atmospheric dynamic model PHYSIC as a meteorological forecast model in nuclear emergency response system

    International Nuclear Information System (INIS)

    It is advantageous for an emergency response system to have a forecast function to provide a time margin for countermeasures in case of a nuclear accident. We propose to apply an atmospheric dynamic model PHYSIC (Prognostic HYdroStatic model Including turbulence Closure model) as a meteorological forecast model in the emergency system. The model uses GPV data which are the output of the numerical weather forecast model of Japan Meteorological Agency as the initial and boundary conditions. The roles of PHYSIC are the interface between GPV data and the emergency response system and the forecast of local atmospheric phenomena within the model domain. This paper presents a scheme to use PHYSIC to forecast local wind and its performance. Horizontal grid number of PHYSIC is fixed to 50 x 50, whereas the mesh and domain sizes are determined in consideration of topography causing local winds at an objective area. The model performance was examined for the introduction of GPV data through initial and boundary conditions and the predictability of local wind field and atmospheric stability. The model performance was on an acceptable level as the forecast model. It was also recognized that improvement of cloud calculation was necessary in simulating atmospheric stability. (author)

    Hypokalemic periodic paralysis is a rare but serious disorder that is typically caused by a channelopathy. Thyrotoxicosis, heavy exercise, high carbohydrate meal and some drugs can trigger channelopathy in genetically predisposed individuals. A 33-year-old male patient presented to the emergency department with weakness in the lower extremities. He stated that he had done heavy physical activity during the previous week. The patient exhibited motor weakness in the lower extremities (2/5 strength) during the physical examination. Initial laboratory tests showed a potassium level of 1.89 mEq/L. The initial electrocardiogram demonstrated T wave inversion and prominent U waves. The patient was treated in the emergency department with oral and intravenous potassium. The physical and ECG symptoms resolved within 16 hours of potassium supplementation and biochemical tests showed normal serum potassium levels. The patient was discharged shortly after the resolution of the symptoms. Weakness is an important but nonspecific symptom that may be brought on by a number of underlying physiological processes. Hypokalemic periodic paralysis is a rare disease that may be triggered by heavy physical activity and presents with recurrent admissions due to weakness. PMID:27336072

    The atmospheric greenhouse effect, an idea that many authors trace back to the traditional works of Fourier (1824), Tyndall (1861), and Arrhenius (1896), and which is still supported in global climatology, essentially describes a fictitious mechanism, in which a planetary atmosphere acts as a heat pump driven by an environment that is radiatively interacting with but radiatively equilibrated to the atmospheric system. According to the second law of thermodynamics such a planetary machine can ...

  12. Job rotation as a factor in reducing physical workload at a refuse collecting department.

    Science.gov (United States)

    Kuijer, P P; Visser, B; Kemper, H C

    1999-09-01

    The effect of job rotation on the physical workload was investigated for male employees working at a refuse collecting department. Before the introduction of job rotation, an employee worked as a street sweeper, as a refuse collector or as a driver. After the introduction of job rotation, every employee was allowed to alternate between two of the three possible jobs during the day, i.e. refuse collecting/street sweeping, refuse collecting/driving or street sweeping/driving. Two non-rotation groups (i.e. refuse collectors and street sweepers) and two rotation groups (i.e. refuse collectors/street sweepers and street sweepers/drivers) were mutually compared. The physical workload was determined by measuring the perceived load, energetic load and postural load during a full working day. Job rotation resulted in a significant decrease of the perceived load and energetic load and a slight decrease of the postural load. The results indicate that the total amount of work performed by means of job rotation resulted in an overall reduced physical workload of the employees of the refuse collecting department.

    The Air Force Academy serves a specialized function as a developer of military officers preparing to lead the nation's air and space forces. Within the Academy, the Physics department focuses on providing a breadth of integrated knowledge in physics and meteorology. To that end technical competency and scientific literacy of both incoming and outgoing students is a significant issue. Despite limited outreach resources, the Physics faculty and staff are very active in K-12 science education and in enhancing general science literacy via public outreach to the community. The department supports more than 1500 public outreach contacts per year. Teachers at all levels are involved in a variety of interactions: one-on-one mentoring, class-to-class pairings of elementary and college physics students, motivational "Physics is Phun" school visits, and numerous activities on the Academy grounds. In this presentation we will discuss the breadth of outreach activities and how they relate the research emphasis areas of the Academy's Physics Department.

  17. Inspection of the defect detection trials plate 4 by the Materials Physics Department, RNL

    International Nuclear Information System (INIS)

    In April 1982, the Materials Physics Department, RNL performed an ultrasonic examination of the clad inlet nozzle specimen DDT4 as part of the UKAEA sponsored defect Detection Trials. The ultrasonic techniques and procedures adopted for this examination and the inspection results as submitted to the inspection organisers are described. A comparison is made of the RNL results with the results of destructive examination of the plate. The results confirm the suitability of combined 700L twin crystal probe and time-of-flight diffraction techniques for the inspection of the inlet nozzle corner region of a PWR pressure vessel.

    Full Text Available Objective: In the present study, to assess the sexual assault victims considering sociodemographic and forensic psychiatry who were examined by our Board of Physical and Mental Health was aimed. Methods: The cases who were examined in Board of Physical and Mental Health in Forensic medicine Department of Dicle University, Faculty of Medicine were assessed retrospectively in terms of age, gender, marital status, education level, relation of the victim with the accused, presence of penetration and disruption of physical and mental health. Results: Among 258 cases, who referred to our board, 196 were female and 62 were male. The age range of the victims was 2 to 50 and average age was detected as 13.1 ± 5.9 years. It was determined that 227 (88% cases were under 18 years and 31 cases (12% were above 18 years. Vaginal and anal penetration was claimed in 48 and 61 cases, respectively; oral + anal penetration was claimed in 11 cases; both vaginal and oral penetration was claimed in two cases. Among 258 cases, 144 cases had no physical and mental disruption; 49 cases were diagnosed with mental and physical health disruption and 65 cases were followed by issuing a preliminary report. Conclusion: As a result of our study any significant relation is not found between impairment in psychological health and sex, marital status, educational level of the victim, age groups, the age difference between the victim and the defendant. Therefore, it is understood that either men or women, married or single, educated or uneducated people are affected emotionally as bad as from sexual assault. This supports the idea that, especially in cases that any findings cannot be obtained with genital and physical examination, psychological evaluation may be important.

    Millennial-scale climate changes during the last glacial period and deglaciation were accompanied by rapid changes in atmospheric CO2 that remain unexplained. While the role of the Southern Ocean as a 'control valve' on ocean-atmosphere CO2 exchange has been emphasized, the exact nature of this role, in particular the relative contributions of physical (for example, ocean dynamics and air-sea gas exchange) versus biological processes (for example, export productivity), remains poorly constrained. Here we combine reconstructions of bottom-water [O2], export production and 14C ventilation ages in the sub-Antarctic Atlantic, and show that atmospheric CO2 pulses during the last glacial- and deglacial periods were consistently accompanied by decreases in the biological export of carbon and increases in deep-ocean ventilation via southern-sourced water masses. These findings demonstrate how the Southern Ocean's 'organic carbon pump' has exerted a tight control on atmospheric CO2, and thus global climate, specifically via a synergy of both physical and biological processes.

  8. Offsite consequence modelling of atmospheric releases: present practice at the CEA/Nuclear Safety Department

    International Nuclear Information System (INIS)

    Anticipated assessment of offsite consequences resulting from an accidental release of radioactivity into the atmosphere is commonly made, for the 1-50 km range, by application of statistical treatments, based on meteorological records, to a set of dose-distance relationships previously calculated by means of the ALICE computer code for various weather conditions, release durations and exposure modes. Input data comprise population distribution around the site and weather data, the latter consisting of mean frequencies per angular sector for short release duration problems or of actual records to account for weather variability in the case of prolonged releases. Consequences are currently expressed in terms of complementary cumulative distribution functions for various dose levels. An application to a reference site is presented

    Full Text Available Physical design of the emergency department (ED has an important effect on its role and function. To date, no guidelines have been introduced to set the standards for the construction of EDs in Iran. In this study we aim to devise an easy-to-use tool based on the available literature and expert opinion for the quick and effective assessment of EDs in regards to their physical design. For this purpose, based on current literature on emergency design, a comprehensive checklist was developed.  Then, this checklist was analyzed by a panel consisting of heads of three major EDs and contradicting items were decided. Overall 178 crude items were derived from available literature. The Items were categorized in to three major domains of Physical space, Equipment, and Accessibility. The final checklist approved by the panel consisted of 163 items categorized into six domains. Each item was phrased as a “Yes or No” question for ease of analysis, meaning that the criterion is either met or not.

  17. Development of a numerical solution method for advection terms and its application to the atmospheric dynamic model, PHYSIC

    International Nuclear Information System (INIS)

    A numerical solution method, HIFI, for advection terms was developed. The method is a hybrid of the newly developed FI method, the first- and second-order upwind schemes. The excursion of the solution caused by the FI method is suppressed by applying the first- and second-order upwind schemes only at the grid points where the excursion of the solution is predicted. This limited use of the high-numerical-diffusion schemes can suppress the numerical diffusion to a reasonably low level. The FI method was designed so as to maximize on accuracy without loosing any stability due to the linear analysis. The accuracy and stability of the FI method vary according to the Courant number and other parameters. HIFI was adopted based on the meteorological sub-model of the numerical atmospheric dispersion model, PHYSIC. Predictability of wind speed in the lower atmosphere could be improved. It is considered that the HIFI method can be applied not only to the meteorological sub-mode in PHYSIC but also to the diffusion calculation of atmospheric radioactive materials. (author)

  18. The Chemistry Departement of the Institute for Nuclear Physics Research, Amsterdam, The Netherlands

    International Nuclear Information System (INIS)

    In 1946, the Institute for Nuclear Physics Research (IKO) in Amsterdam was founded as a typical post World War II effort to cope with the surge in scientific research, primarily in the USA. At present, the Institute encompasses almost 250 workers - including a Philips research group - out of which nearly 30 are members of the Chemistry Department. In the beginning, the investigations dealt with more or less conventional tracerwork using long-lived radionuclides produced in nuclear reactors. This changed rapidly with the synchrocyclotron coming into operation in 1947. The present can be best characterized as a sort of a transition state. Emphasis has been laid upon more typical chemical aspects of the research program: a shift from ''nuclear'' chemistry to ''radio'' chemistry. The future is determined by the 500 MeV linear electron accelerator, dubbed MEA (Medium Energy Accelerator) already under construction. (T.G.)

    The first article in this report, although dealing with simple terrain, summarizes an effort to obtain measures of parameters important in transport and diffusion in the lower atmosphere solely by use of a Doppler acoustic sounding system. The second article describes participation in a multiagency experiment (Shoreline Environment Atmospheric Dispersion Experiment, SEADEX) to study the fate of materials released over a surface with notable surface nonuniformities, specifically at a coastal nuclear power plant during onshore flow conditions. The third and fourth articles in this report address research on the local behavior of pollutants emitted from diesel engines in urban areas. Most effort was directed toward field studies on circulation patterns in street canyons, exchange rates with the atmosphere above rooftops, and characterization of particles in outdoor urban microclimates. The remainder of the report is quite diverse and contains multiple articles on perhaps only one or two types of research. One is numerical modeling of the behavior of atmospheric pollutants, especially gaseous and particulate substances associated with acid deposition. The modeling and theoretical capabilities have been developed in part to consider potential nonlinear relationships between anthropogenic emissions of sulfur and nitrogen compounds and the distant deposition of resulting acidifying substances. On the experimental side, field phases of research designed to compare methods of analyses of precipitation samples and to study local urban effects on precipitation chemistry were completed. Each report is indexed separately.

  13. Numerical simulations of land surface physical processes and land-atmosphere interactions over oasis-desert/Gobi region

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    A land-surface physical process model was coupled with a mesoscale atmospheric model. This cou- pled model was then used to simulate the interactions between land and the atmosphere, including surface temperature, net radiation, sensible heat flux and latent heat flux over a desert/Gobi with an oasis in northwestern semiarid regions in China. Comparisons between observations and simulations were made over the oasis and the desert/Gobi, respectively. Both cold island effect and wet island ef- fect, the so-called oasis effect, were observed and simulated. Lower temperature, higher specific hu- midity and weaker turbulent transfer were present over the oasis than the desert/Gobi. A subsidence occurred over the oasis, leading to a thermally-generated mesoscale circulation.

  15. Implementation of U.S. Department of Energy physical protection upgrades in Lithuania and Uzbekistan

    International Nuclear Information System (INIS)

    Since 1994, the U.S. Department of Energy (DOE) has provided cooperative assistance to the non-nuclear weapons states of the Former Soviet Union. This effort, within DOE's program of Material Protection, Control, and Accounting (MPC ampersand A), identified the Institute of Nuclear Physics (INP) in Uzbekistan and the Ignalina Nuclear Power Plant (INPP) in Lithuania as sites for cooperative MPC ampersand A projects. The INP, located just outside of Tashkent, is the site of a 10-megawatt WWR-SM research reactor. This reactor is expected to remain operational as a major nuclear research and isotope production reactor for Central Asia. The INPP, located 100 kilometers northeast of the capital city of Vilnius, consists of two Russian-made RBMK reactors with a combined power output of 3,000 megawatts (electric). This power plant has been the subject of international safety and security concerns, which prompted DOE's cooperative assistance effort. This paper describes U.S. progress in a multi-national effort directed at implementing physical protection upgrades in Lithuania and Uzbekistan. The upgrades agreed upon between DOE and the INP and between DOE and the INPP have been designed to interface with upgrades being implemented by other donor countries. DOE/INPP upgrade projects include providing training on U.S. approaches to physical protection, access control through the main vehicle portal, a hardened central alarm station, and improved guard force communications. DOE/INP upgrade projects in Uzbekistan include an access control system, a hardened fresh fuel storage vault, an interior intrusion detection and assessment system, and an integrated alarm display and assessment system

  19. Physical and Mathematical Properties of a Quasi-Geostrophic Model of Intermediate Complexity of the Mid-Latitudes Atmospheric Circulation

    CERN Document Server

    Lucarini, V; VItolo, R; Itolo, Renato V; Lucarini, Valerio; Speranza, Antonio

    2005-01-01

    A quasi-geostrophic intermediate complexity model is considered, providing a schematic representation of the baroclinic conversion processes which characterize the physics of the mid-latitudes atmospheric circulation. The model is relaxed towards a given latitudinal temperature profile, which acts as baroclinic forcing, controlled by a parameter TE determining the forced equator-to-pole temperature gradient. As TE increases, a transition takes place from a stationary regime to a periodic regime, and eventually to an earth-like chaotic regime where evolution takes place on a strange attractor. The dependence of the attractor dimension, metric entropy, and bounding box volume in phase space is studied by varying both TE and model resolution. The statistical properties of observables having physical relevance, namely the total energy of the system and the latitudinally averaged zonal wind, are also examined. It is emphasized that while the attractor's properties are quite sensitive to model resolution, the globa...

  1. An efficient physics-based preconditioner for the fully implicit solution of small-scale thermally driven atmospheric flows

    International Nuclear Information System (INIS)

    In atmospheric flow situations typical of a small-scale atmospheric thermal, a separation of time scales exists between the fast sound wave time scale and the advective time scale. Atmospheric models have been designed to take advantage of this disparity of time scales with numerical approaches such as the semi-implicit or split-explicit approach being used to efficiently step over the fast sound waves. Some of these numerical approaches are first order in time. To improve accuracy over these methods, a fully implicit and nonlinearly consistent (INC) flow solver has been developed for the Navier-Stokes equation set. In our INC method, the equation set is solved by use of the Jacobian-free Newton-Krylov (JFNK) method. An efficient preconditioner has been developed which uses the semi-implicit method to solve the governing equations. Being that this preconditioner was designed to attack the fastest waves in the system and not other features in the implicit system such as advection or turbulent diffusion, the preconditioning technique is labeled as a physics-based preconditioner. A variety of linear solvers including SSOR, Krylov methods and/or multigrid approaches are used to approximately invert the pressure matrix in the semi-implicit algorithm. A suite of simulations will be conducted utilizing different linear solvers for the simple problem of the bouyant rise of a warm bubble. The problem will also document the ability of the INC approach to achieve second order in time accuracy

  2. Physical, chemical and sensory changes in irradiated fresh pork packaged in modified atmosphere

    International Nuclear Information System (INIS)

    The effects of irradiation dose (0, 0.5 and 1.0 kGy), headspace oxygen (0, 10 and 20% O2 balance nitrogen) and storage temperature (5, 15 and 25 degrees C) on the physical, chemical and sensory changes in fresh pork were studied using factorial design experiments. Irradiation in the absence of oxygen extended the sensory shelf life of pork from 9 to 26 days at 5 degrees C and from 2 to 2 days at 25 degrees C. Oxygen in the package headspace combined with irradiation adversely affected physical, chemical and sensory characteristics of the end product

    The LASP Interactive Solar Irradiance Datacenter, LISIRD, http://lasp.colorado.edu/lisird, allows the science community and the public to explore and access solar irradiance and related data sets using convenient, interactive or scriptable, standards-based interfaces. LISIRD's interactive plotting allows users to investigate and download irradiance data sets from a variety of sources, including space missions, ground observatories, and modeling efforts. LISIRD's programmatic interfaces allow software-level data retrievals and facilitate automation. This presentation will describe the current state of LISIRD, provide details of the data sets it serves, outline data access methods, identify key technologies in-use, and address other related aspects of serving spectral and other time series data. We continue to improve LISIRD by integrating new data sets, and also by advancing its data management and presentation capabilities to meet evolving best practices and community needs. LISIRD is hosted and operated by the Laboratory for Atmospheric and Space Physics, LASP, which has been a leader in Atmospheric and Heliophysics science for over 60 years. LASP makes a variety of space-based measurements of solar irradiance, which provide crucial input for research and modeling in solar-terrestrial interactions, space physics, planetary, atmospheric, and climate sciences. These data sets consist of fundamental measurements, composite data sets, solar indices, space weather products, and models. Current data sets available through LISIRD originate from the SORCE, SDO (EVE), UARS (SOLSTICE), TIMED (SEE), and SME space missions, as well as several other space and ground-based projects. LISIRD leverages several technologies to provide flexible and standards-based access to the data holdings available through LISIRD. This includes internet-accessible interfaces that permit data access in a variety of formats, data subsetting, as well as program-level access from data analysis

  4. Physical conditions and nature of chemical anomalies in the atmosphere of Sirius A

    Leushin, V. V.; Topilskaya, G. P.; Musaev, F. A.

    On the basis of the analysis of the observed equivalent line widths of Fe I, Fe II, Ti II in the spectra of alpha CMa and o Peg and calculation of abundances of these elements, oscillator strengths of the lines used are refined. With the improved oscillator strengths the iron and titanium abundances in the atmosphere of Sirius A are obtained with a higher accuracy than previously: lg N(Fe I) = 7.899 +/- 0.011, lg N(Fe II) = 7.908 +/- 0.010, lg N(Ti II) = 5.289 +/- 0.020. The improved accuracy allowed one to conclude that the surface magnetic field is absent in the atmosphere of Sirius A: H_s = 0+/-100 G. The equivalent widths of helium carbon and nitrogen lines of the red region of the spectrum are measured. The calculations of these lines with allowance for their blending with lines of other elements show normal helium abundance. From a comparison of features of alpha CMa and o Peg an assumption is made on possible reasons for the existence of the phenomenon of Am stars.

The aim of this study is to measure the Facebook addiction levels of 274 students at the Physical Education and Sports Teaching Department in a public university in Turkey and to examine their Facebook addiction levels against a number of variables. Descriptive method was used within the framework of the study and the “Facebook Addiction Survey” developed by Çam and İşbulan (2012 was used as the data collection instrument. The results of the study show the students had low levels of Facebook addiction. On the other hand, when the Facebook addiction level mean scores were compared, male students were seen to have higher scores than female students. Students in the 3rd grade had higher mean scores than those in the 1st and 2nd grades. Although Facebook addiction is not a problem among the students, proactive action is needed to enhance student awareness of the problem and ensure future teachers can be role models in an addiction‐free academic environment.  

  7. Activities of JAERI's health physics department for the criticality accident of JCO

    International Nuclear Information System (INIS)

    This report describes early health physics activities from September 30 to October 1 taken by the authors' department after the JCO accident. They firstly knew the accident at around 12:20 (about 2 hr after the criticality). The activities involved the planning of schedule for ending the criticality; calculation of scheduled dose for the work to end it; dose measurement around JCO site; loaning out of devices for measuring neutron and of personal dose-meter; collection and radioactivity measurement of dust and soil, and of drinking water; and examination for contamination of people around the site, of their houses inside and of school gardens and equipments. The dose was scheduled to be firstly 20 mSv and then changed to 50 mSv due to the actual measurement at the accident site. The working time was to be 3 min at the site. The work was on either the dose or time. Radiation monitoring outside the JCO site revealed the presence of Na-24 and Cs-138: neutron dose was 10 times as high as γ-ray dose. The time course of dose rate change was found to be in parallel with the progress of works to end the criticality. (K.H.)

    In the August 1993 Health Physics Society (HPS) newsletter, the HPS Scientific and Public Issues Committee published a Position Statement entitled open-quotes Radiation Protection of the Public and the Environment.close quotes. In this article, this HPS committee made the statement that they were deeply concerned by the trend for agencies to incorporate the ALARA concept as a regulatory requirements, without providing specific guidance as to what it means and how to implement it consistently. The HPS position paper was in response to the DOE notice on proposed rulemaking for Title 10 Code of Federal Regulations Part 834, open-quotes Radiation Protection of the Public and the Environmentclose quotes (10 CFR 834). In the notice of proposed rulemaking for 10 CFR 834, the Department of Energy (DOE) defined ALARA as follows: open-quotes As used in this part, ALARA is not a dose limit, but rather a process which has the objective of attaining doses as far below the applicable limit of this part as is reasonably achievableclose quotes (10 CFR 834.2, p. 16283 of the Federal Register). The HPS position paper continues, open-quotes The section goes on to elaborate on what is meant by a process without providing sufficient guidance to assure uniform applicability of the process.close quotes. Although this concern is directed towards the ALARA process as it relates to the environment, the Office of Health, which is responsible for occupational workers, shares the same definition for ALARA

  12. The primary design of advanced ground-based atmospheric microwave sounder and retrieval of physical parameters

    International Nuclear Information System (INIS)

    This paper introduces a prototype of ground-based atmospheric microwave sounder that operates in K-band from 22 to 31 GHz and V-band from 51 to 59 GHz. Different from the MP3000A and RPG, the sounder adopts independent dual-band reflectors instead of sharing a dual-band reflector. The direct detect type receiver is applied, which is of smaller size, higher sensitivity, efficient data observing and lower nonlinear error than the widely used superheterodyne receiver. The observing brightness temperatures from this prototype agree well with the simulated brightness temperatures according to the ground-based radiative transfer theory. We use the artificial neural network (ANN) algorithm to retrieve temperature profiles, which has higher spatial resolution especially in the capping inversion when compared with the linear regression algorithm. The temperature retrievals are comparable with the retrievals from RPG and MP3000A retrieval models and have a smaller bias in some certain regions.

    2016-01-01

    The atmospheric pressure PECVD deposition and texturization of hydrophobic coatings using liquid fluorinated C6F12 and C6F14 precursors are investigated. The effect of the carrier gas (argon and helium) is discussed in terms of the behavior of the gas phase and of the characteristics of the deposited film. Mass spectrom-etry measurements indicate that the fragmentation is higher with argon while helium reacts very easily with oxygen impurities leading to the formation of CxFyOz compounds. These observations are consistent with the chemical composition of the films determined by XPS and the variation in the deposition rate. Moreover, the streamers present in the argon discharge affect the morphology of the surface by increasing the roughness, which leads to the increase in the hydrophobicity of the coatings.

    2014-12-01

    CHUVA, meaning "rain" in Portuguese, is the acronym for the Cloud processes of tHe main precipitation systems in Brazil: A contribUtion to cloud resolVing modeling and to the GPM (GlobAl Precipitation Measurement). The CHUVA project has conducted six field campaigns; the last campaign was held in Manaus in 2014 jointly with GoAmazon and ACRIDICON. CHUVA's main scientific motivation is to contribute to the understanding of cloud processes, which represent one of the least understood components of the weather and climate system. This study will briefly describe the CHUVA project and the main scientific results obtained in the Amazon region. Specifically, we will describe the results of one year radar observation of Manaus rainfall and the relationship with black carbon. The results indicate that the aerosol influence on precipitating systems is modulated by the atmospheric instability degree. For stable atmospheres, the higher the aerosol concentration, the lower the precipitation over the region. On the other hand, for unstable cases, higher concentrations of particulate material are associated with more precipitation, elevated presence of ice and larger rain cells, which suggests an association with long lived systems. Also we will describe some preliminary results obtained during GoAmazon describing the cloud and rainfall size distribution (DSD). The DSD was adjusted to the gamma function using the momentum method and disposed in the three-dimensional space of the gamma parameters: the intercept, the shape and the width. Each point in this three-dimensional space corresponds to a specific DSD and the ensemble of points describes all regimes of precipitation in Amazon. Based in this Gamma space we will discuss the characteristics of the rainfall regime and anthropogenic features.

    Energy Technology Data Exchange (ETDEWEB)

    1990-06-01

    This 1989 Annual Report from Pacific Northwest Laboratory (PNL) to the US Department of Energy (DOE) describes research in environment, safety, and health conducted during fiscal year 1989. The report again consists of five parts, each in a separate volume. This volume contains research in the atmospheric sciences. Currently, the broad goals of atmospheric research at PNL are to describe and predict the nature and fate of atmospheric contaminants and to develop an understanding of the atmospheric processes contributing to their distribution on local, regional, continental, and global scales in the air, in clouds, and on the surface. The redistribution and long-range transport of transformed contaminants passing through clouds is recognized as a necessary extension of our research to even larger scales in the future. Eventually, large-scale experiments on cloud processing and redistribution of contaminants will be integrated into the national program on global change, investigating how energy pollutants affect aerosols and clouds and the transfer of radiant energy through them. As the significance of this effect becomes clear, its global impact on climate will be studied through experimental and modeling research. The description of ongoing atmospheric research at PNL is organized in terms of the following study areas: atmospheric studies in complex terrain, large-scale atmospheric transport and processing of emissions, and climate change. This report describes the progress in FY 1989 in each of these areas. A divider page summarizes the goals of each area and lists project titles that support research activities. 9 refs., 2 figs., 3 tabs.

    Full Text Available Veteran activity levels may decrease between Active Duty and postdeployment. We examined attitudes and changes in self-reported activities between the two in Operation Iraqi Freedom/Operation Enduring Freedom (OIF/OEF veterans using Department of Veterans Affairs (VA services. We conducted an online cross-sectional survey (June-August 2008 of postdeployment OIF/OEF veterans registered with the VA Ann Arbor Healthcare System, Ann Arbor, Michigan. Descriptive statistics summarized demographic data and attitudes, while regression analyses compared physical activities during Active Duty with physical activities postdeployment. Participants (n = 319, 15.6% response rate reported that they believe staying physically fit is important, they worry about gaining weight, and they believe exercise will keep them healthy (77%, 72%, and 90% agree or strongly agree, respectively. Running (30.0%, Exercise with Gym Equipment (21.5%, Occupational Activities (14.9%, and Walking (13.0% were the most frequently reported Active Duty physical activities. The most frequently reported postdeployment physical activities included Walking (21.1%, Running (18.5%, and Exercise with Gym Equipment (17.9%. Health problems (39% and chronic pain (52% were common barriers to physical activity. Postdeployment OIF/OEF veterans using the VA believe physical activity is beneficial, yet many report health problems and/or chronic pain that makes exercise difficult. Physical activity promotes health, and strategies are needed to facilitate physical activity in this population.

    2013-11-01

    This paper aims to present to the science community another way to fly in atmosphere, a way which is much more cheaper, efficient, safe and easy. Over the years scientists have been trying to find a way to built the vertically taking off vehicles but there have been no satisfactory success(what have been found was very expensive), Even aircrafts we know now need very sophisticated and expensive engines and not efficient enough. This way of flying may help our governments to spend less money on technologies and will help people to travel at very low prices so that, it may be a solution to the crisis which the world faces nowadays. In other words, it is my proposal to the next generation technologies we was looking for for years because everything can fly from the car to the trucks, the spaceships and even the hotels maybe constructed and fly as we construct the ships which sail in the oceans. My way of flying will have many applications in all the aspect of travel as it is going to be explained.

  19. Some studies relating to solar-terrestrial physics and the middle atmosphere

    International Nuclear Information System (INIS)

    A review is given of observed variations in the Earth's rotation rate, and mechanisms by which the Sun might affect the length of day are discussed. Solar activity and means by which the planets might influence this activity are considered. Observed solar activity - weather correlations, in particular in relation to the sun-based, interplanetary magnetic sector structure and some of the suggested mechanisms for producing these correlations are discussed. The simple photochemical production of ozone in the middle atmosphere and the manner in which cosmic rays, through the production of nitrogen compounds, alter the ozone concentration at high altitudes is described. A computer model is developed which calculates ozone concentrations and energy absorption at any altitude, latitude, longitude and time of year and used to predict ozone and temperature change profiles over a 14-day cycle of ultra-violet changes. The existence of a solar magnetic sector linked variation of the high latitude, high altitude NO concentration is postulated and this is incorporated into the computer model to predict a temperature oscillation over a 14-day cycle which varies with geographic latitude and longitude. This effect is investigated in detail. (UK)

    Full Text Available The buildings are usually meet many changes before the end of their physical life. If these changes are not met by the buildings, the functional obsolescence is inevitable. The user requirements must be determined correctly during the design process for delaying the functional obsolescence as possible. Belong to this aim, the effects of user requirements on functional changes were tried to determine in the study which was held in physical therapy and rehabilitation departments. After examining the data, the results which are given below was founded;If the space and equipments are not in right dimensions and positions, the users can not use the spaces comfortably. The spaces that users have great problems in the usage of these areas are toilets and baths. The location of stairs and elevators in these units are another important data during design process. If these elements are located in the centre or in the sides of the building, the usage might be provided easily. As a result, it was determined that the most important factors primarily in the content of user requirements are the location of toilets, baths, stairs and elevators.In the physical therapy and rehabilitation departments that the user requirements can not be eliminated, is tried to produce different solutions. In physical therapy and rehabilitation departments, the units which are inadequate, are moved different sections and the usage of these units can not be functional.Belong to these data, the properties of physical spaces are determined by evaluating the questionnaire. The user requirements, location of toilets, baths, stairs and elevators were examined in different physical therapy and rehabilitation departments and determined their effects on design.

  2. The contributions of Lewis Fry Richardson to drainage theory, soil physics, and the soil-plant-atmosphere continuum

    Science.gov (United States)

    Knight, John; Raats, Peter

    2016-04-01

    The EGU Division on Nonlinear Processes in Geophysics awards the Lewis Fry Richardson Medal. Richardson's significance is highlighted in http://www.egu.eu/awards-medals/portrait-lewis-fry-richardson/, but his contributions to soil physics and to numerical solutions of heat and diffusion equations are not mentioned. We would like to draw attention to those little known contributions. Lewis Fry Richardson (1881-1953) made important contributions to many fields including numerical weather prediction, finite difference solutions of partial differential equations, turbulent flow and diffusion, fractals, quantitative psychology and studies of conflict. He invented numerical weather prediction during World War I, although his methods were not successfully applied until 1950, after the invention of fast digital computers. In 1922 he published the book `Numerical weather prediction', of which few copies were sold and even fewer were read until the 1950s. To model heat and mass transfer in the atmosphere, he did much original work on turbulent flow and defined what is now known as the Richardson number. His technique for improving the convergence of a finite difference calculation is known as Richardson extrapolation, and was used by John Philip in his 1957 semi-analytical solution of the Richards equation for water movement in unsaturated soil. Richardson's first papers in 1908 concerned the numerical solution of the free surface problem of unconfined flow of water in saturated soil, arising in the design of drain spacing in peat. Later, for the lower boundary of his atmospheric model he needed to understand the movement of heat, liquid water and water vapor in what is now called the vadose zone and the soil plant atmosphere system, and to model coupled transfer of heat and flow of water in unsaturated soil. Finding little previous work, he formulated partial differential equations for transient, vertical flow of liquid water and for transfer of heat and water vapor. He

The findings showed that the students continue to have the same misconceptions on concepts, such as the students of the high school. The research indicates that the students’ misconceptions remain largely throughout secondary education, which is a proof that there is no effort, where appropriate for conceptual change, according to the constructive model of learning and teaching physics. The objective intended to be reached in this communication is to provide an exchange forum of ideas that would help instructors originate the cause, and subsequently avoid misconceptions in freshman Physics education.

    The atmospheric particulate matter has a large impact on climate, biosphere behaviour and human health. Its study is complex because of large number of species are present at low concentrations and the continuous time evolution, being not easily separable from meteorology, and transport processes. Closed systems have been proposed by isolating specific reactions, pollutants or products and controlling the oxidizing environment. High volume simulation chambers, such as EUropean PHOtoREactor (EUPHORE), are an essential tool used to simulate atmospheric photochemical reactions. This communication describes the last results about the reactivity of prominent atmospheric pollutants and the subsequent particulate matter formation. Specific experiments focused on organic aerosols have been developed at the EUPHORE photo-reactor. The use of on-line instrumentation, supported by off-line techniques, has provided well-defined reaction profiles, physical properties, and up to 300 different species are determined in particulate matter. The application fields include the degradation of anthropogenic and biogenic pollutants, and pesticides under several atmospheric conditions, studying their contribution on the formation of secondary organic aerosols (SOA). The studies performed at the EUPHORE have improved the mechanistic studies of atmospheric degradation processes and the knowledge about the chemical and physical properties of atmospheric particulate matter formed during these processes.

  8. Improvement of a mesoscale atmospheric dynamic model PHYSIC. Utilization of output from synoptic numerical prediction model for initial and boundary condition

    International Nuclear Information System (INIS)

    This report describes the improvement of the mesoscale atmospheric dynamic model which is a part of the atmospheric dispersion calculation model PHYSIC. To introduce large-scale meteorological changes into the mesoscale atmospheric dynamic model, it is necessary to make the initial and boundary conditions of the model by using GPV (Grid Point Value) which is the output of the numerical weather prediction model of JMA (Japan Meteorological Agency). Therefore, the program which preprocesses the GPV data to make a input file to PHYSIC was developed and the input process and the methods of spatial and temporal interpolation were improved to correspond to the file. Moreover, the methods of calculating the cloud amount and ground surface moisture from GPV data were developed and added to the model code. As the example of calculation by the improved model, the wind field simulations of a north-west monsoon in winter and a sea breeze in summer in the Tokai area were also presented. (author)

    The UCB submm heterodyne receiver is a complete system for high-resolution astronomical spectroscopy in the 350-micron and 450-micron atmospheric windows. This compact system mounts directly at the Cassegrain focus of large optical and IR telescopes. It consists of a laser local oscillator, open structure mixer, quasi-optical coupling system, a broad-band IF system, and an acoustooptical spectrometer. The local oscillator is a 1-m-long submm laser optically pumped by a CO2 laser. The mixer is a quasi-optical corner-cube antenna structure and Schottky diode. The mixer is currently operated at room temperature, and its performance at 77 K is being evaluated. The system noise temperature is less than 7000 K SSB during observations.

  6. On the physical processes ruling an atmospheric pressure air glow discharge operating in an intermediate current regime

    International Nuclear Information System (INIS)

    Low-frequency (100 Hz), intermediate-current (50 to 200 mA) glow discharges were experimentally investigated in atmospheric pressure air between blunt copper electrodes. Voltage–current characteristics and images of the discharge for different inter-electrode distances are reported. A cathode-fall voltage close to 360 V and a current density at the cathode surface of about 11 A/cm2, both independent of the discharge current, were found. The visible emissive structure of the discharge resembles to that of a typical low-pressure glow, thus suggesting a glow-like electric field distribution in the discharge. A kinetic model for the discharge ionization processes is also presented with the aim of identifying the main physical processes ruling the discharge behavior. The numerical results indicate the presence of a non-equilibrium plasma with rather high gas temperature (above 4000 K) leading to the production of components such as NO, O, and N which are usually absent in low-current glows. Hence, the ionization by electron-impact is replaced by associative ionization, which is independent of the reduced electric field. This leads to a negative current-voltage characteristic curve, in spite of the glow-like features of the discharge. On the other hand, several estimations show that the discharge seems to be stabilized by heat conduction; being thermally stable due to its reduced size. All the quoted results indicate that although this discharge regime might be considered to be close to an arc, it is still a glow discharge as demonstrated by its overall properties, supported also by the presence of thermal non-equilibrium

    There have been three physics meetings since the last CMS week: “physics days” on March 27-29, the Physics/ Trigger week on April 23-27 and the most recent physics days on May 22-24. The main purpose of the March physics days was to finalize the list of “2007 analyses”, i.e. the few topics that the physics groups will concentrate on for the rest of this calendar year. The idea is to carry out a full physics exercise, with CMSSW, for select physics channels which test key features of the physics objects, or represent potential “day 1” physics topics that need to be addressed in advance. The list of these analyses was indeed completed and presented in the plenary meetings. As always, a significant amount of time was also spent in reviewing the status of the physics objects (reconstruction) as well as their usage in the High-Level Trigger (HLT).

    International Nuclear Information System (INIS)

    Evidence for ν-barμ → ν-bare oscillations has been reported at LAMPF using the LSND detector. Further evidence for neutrino mixing comes from the solar neutrino deficit and the atmospheric neutrino anomaly. All of these anomalies require new physics. It is shown that all of these anomalies can be explained if the standard model is enlarged so that an unbroken parity symmetry can be defined. This explanation holds independently of the actual model for neutrino masses. Thus, it is argued that parity symmetry is not only a beautiful candidate for a symmetry beyond the standard model, but it can also explain the known neutrino physics anomalies. 41 refs

    A remarkable amount of progress has been made in Physics since the last CMS Week in June given the exponential growth in the delivered LHC luminosity. The first major milestone was the delivery of a variety of results to the ICHEP international conference held in Paris this July. For this conference, CMS prepared 15 Physics Analysis Summaries on physics objects and 22 Summaries on new and interesting physics measurements that exploited the luminosity recorded by the CMS detector. The challenge was incorporating the largest batch of luminosity that was delivered only days before the conference (300 nb-1 total). The physics covered from this initial running period spanned hadron production measurements, jet production and properties, electroweak vector boson production, and even glimpses of the top quark. Since then, the accumulated integrated luminosity has increased by a factor of more than 100, and all groups have been working tremendously hard on analysing this dataset.

    Full Text Available OBJECTIVES: To describe nationally representative outcomes of physical abuse injuries in children necessitating Emergency Department (ED visits in United States. The impact of various injuries on mortality is examined. We hypothesize that physical abuse resulting in intracranial injuries are associated with worse outcome. MATERIALS AND METHODS: We performed a retrospective analysis of the Nationwide Emergency Department Sample (NEDS, the largest all payer hospital based ED database, for the years 2008-2010. All ED visits and subsequent hospitalizations with a diagnosis of "Child physical abuse" (Battered baby or child syndrome due to various injuries were identified using ICD-9-CM (International Classification of Diseases, 9th Revision, Clinical Modification codes. In addition, we also examined the prevalence of sexual abuse in this cohort. A multivariable logistic regression model was used to examine the association between mortality and types of injuries after adjusting for a multitude of patient and hospital level factors. RESULTS: Of the 16897 ED visits that were attributed to child physical abuse, 5182 (30.7% required hospitalization. Hospitalized children were younger than those released treated and released from the ED (1.9 years vs. 6.4 years. Male or female partner of the child's parent/guardian accounted for >45% of perpetrators. Common injuries in hospitalized children include- any fractures (63.5%, intracranial injuries (32.3% and crushing/internal injuries (9.1%. Death occurred in 246 patients (13 in ED and 233 following hospitalization. Amongst the 16897 ED visits, 1.3% also had sexual abuse.

  3. Efficient and physically accurate modeling and simulation of anisoplanatic imaging through the atmosphere: a space-variant volumetric image blur method

    Science.gov (United States)

    Reinhardt, Colin N.; Ritcey, James A.

    2015-09-01

    We present a novel method for efficient and physically-accurate modeling & simulation of anisoplanatic imaging through the atmosphere; in particular we present a new space-variant volumetric image blur algorithm. The method is based on the use of physical atmospheric meteorology models, such as vertical turbulence profiles and aerosol/molecular profiles which can be in general fully spatially-varying in 3 dimensions and also evolving in time. The space-variant modeling method relies on the metadata provided by 3D computer graphics modeling and rendering systems to decompose the image into a set of slices which can be treated in an independent but physically consistent manner to achieve simulated image blur effects which are more accurate and realistic than the homogeneous and stationary blurring methods which are commonly used today. We also present a simple illustrative example of the application of our algorithm, and show its results and performance are in agreement with the expected relative trends and behavior of the prescribed turbulence profile physical model used to define the initial spatially-varying environmental scenario conditions. We present the details of an efficient Fourier-transform-domain formulation of the SV volumetric blur algorithm and detailed algorithm pseudocode description of the method implementation and clarification of some nonobvious technical details.

  4. Influence of the micro-physical properties of the aerosol on the atmospheric correction of OLI data acquired over desert area

    This paper focuses on the evaluation of surface reflectance obtained by different atmospheric correction algorithms of the Landsat 8 OLI data considering or not the micro-physical properties of the aerosol when images are acquired in desert area located in South-West of Nile delta. The atmospheric correction of remote sensing data was shown to be sensitive to the aerosol micro-physical properties, as reported in Bassani et al., 2012. In particular, the role of the aerosol micro-physical properties on the accuracy of the atmospheric correction of remote sensing data was investigated [Bassani et al., 2015; Tirelli et al., 2015]. In this work, the OLI surface reflectance was retrieved by the developed OLI@CRI (OLI ATmospherically Corrected Reflectance Imagery) physically-based atmospheric correction which considers the aerosol micro-physical properties available from the two AERONET stations [Holben et al., 1998] close to the study area (El_Farafra and Cairo_EMA_2). The OLI@CRI algorithm is based on 6SV radiative transfer model, last generation of the Second Simulation of a Satellite Signal in the Solar Spectrum (6S) radiative transfer code [Kotchenova et al., 2007; Vermote et al., 1997], specifically developed for Landsat 8 OLI data. The OLI reflectance obtained by the OLI@CRI was compared with reflectance obtained by other atmospheric correction algorithms which do not consider micro-physical properties of aerosol (DOS) or take on aerosol standard models (FLAASH, implemented in ENVI software). The accuracy of the surface reflectance retrieved by different algorithms were calculated by comparing the spatially resampled OLI images with the MODIS surface reflectance products. Finally, specific image processing was applied to the OLI reflectance images in order to compare remote sensing products obtained for same scene. The results highlight the influence of the physical characterization of aerosol on the OLI data improving the retrieved atmospherically corrected

The summer was filled with preparations of new Monte Carlo samples based on CMSSW_3, the finalization of all the 10 TeV physics analyses [in total 50 analyses were approved] and the preparations for the Physics Week in Bologna. A couple weeks later, the “October Exercise” commenced and ran through an intense two-week period. The Physics Days in October were packed with a number of topics that are relevant to data taking, in a number of “mini-workshops”: the luminosity measurement, the determination of the beam spot and the measurement of the missing transverse energy (MET) were the three main topics.  Physics Week in Bologna The second physics week in 2009 took place in Bologna, Italy, on the week of Sep 7-11. The aim of the week was to review and establish how ready we are to do physics with the early collisions at the LHC.

    In this paper it is explained the construction and utility of a didactic exhibit about the effect of aerosol in atmosphere on electromagnetic wave propagation. The exhibit is composed by a lamp simulating the Sun, a Plexiglas case (the atmosphere), white or black panels (surface albedo), a combustion chamber to supply aerosol inside the case and other equipments. There are temperature and relative humidity of air sensors and 5 light sensors to measure direct and scattered light. It is possible to measure the cooling effect of aerosol inside the case and the increasing in scattered light.

    The all-plenary format of the CMS week in Cyprus gave the opportunity to the conveners of the physics groups to present the plans of each physics analysis group for tackling early physics analyses. The presentations were complete, so all are encouraged to browse through them on the Web. There is a wealth of information on what is going on, by whom and on what basis and priority. The CMS week was followed by two CMS “physics events”, the ICHEP08 days and the physics days in July. These were two weeks dedicated to either the approval of all the results that would be presented at ICHEP08, or to the review of all the other Monte-Carlo based analyses that were carried out in the context of our preparations for analysis with the early LHC data (the so-called “2008 analyses”). All this was planned in the context of the beginning of a ramp down of these Monte Carlo efforts, in anticipation of data.  The ICHEP days are described below (agenda and talks at: http://indic...

    There have been two plenary physics meetings since the December CMS week. The year started with two workshops, one on the measurements of the Standard Model necessary for “discovery physics” as well as one on the Physics Analysis Toolkit (PAT). Meanwhile the tail of the “2007 analyses” is going through the last steps of approval. It is expected that by the end of January all analyses will have converted to using the data from CSA07 – which include the effects of miscalibration and misalignment. January Physics Days The first Physics Days of 2008 took place on January 22-24. The first two days were devoted to comprehensive re¬ports from the Detector Performance Groups (DPG) and Physics Objects Groups (POG) on their planning and readiness for early data-taking followed by approvals of several recent studies. Highlights of POG presentations are included below while the activities of the DPGs are covered elsewhere in this bulletin. January 24th was devo...

    The months that have passed since the last CMS Bulletin have been a very busy and exciting time for CMS physics. We have gone from observing the very first 8TeV collisions produced by the LHC to collecting a dataset of the collisions that already exceeds that recorded in all of 2011. All in just a few months! Meanwhile, the analysis of the 2011 dataset and publication of the subsequent results has continued. These results come from all the PAGs in CMS, including searches for the Higgs boson and other new phenomena, that have set the most stringent limits on an ever increasing number of models of physics beyond the Standard Model including dark matter, Supersymmetry, and TeV-scale gravity scenarios, top-quark physics where CMS has overtaken the Tevatron in the precision of some measurements, and bottom-quark physics where CMS made its first discovery of a new particle, the Ξ*0b baryon (candidate event pictured below).

    The time period between the last CMS week and this June was one of intense activity with numerous get-together targeted at addressing specific issues on the road to data-taking. The two series of workshops, namely the “En route to discoveries” series and the “Vertical Integration” meetings continued.   The first meeting of the “En route to discoveries” sequence (end 2007) had covered the measurements of the Standard Model signals as necessary prerequisite to any claim of signals beyond the Standard Model. The second meeting took place during the Feb CMS week and concentrated on the commissioning of the Physics Objects, whereas the third occurred during the April Physics Week – and this time the theme was the strategy for key new physics signatures. Both of these workshops are summarized below. The vertical integration meetings also continued, with two DPG-physics get-togethers on jets and missing ET and on electrons and photons. ...

    Since the last CMS Week, all physics groups have been extremely active on analyses based on the full 2010 dataset, with most aiming for a preliminary measurement in time for the winter conferences. Nearly 50 analyses were approved in a “marathon” of approval meetings during the first two weeks of March, and the total number of approved analyses reached 90. The diversity of topics is very broad, including precision QCD, Top, and electroweak measurements, the first observation of single Top production at the LHC, the first limits on Higgs production at the LHC including the di-tau final state, and comprehensive searches for new physics in a wide range of topologies (so far all with null results unfortunately). Most of the results are based on the full 2010 pp data sample, which corresponds to 36 pb-1 at √s = 7 TeV. This report can only give a few of the highlights of a very rich physics program, which is listed below by physics group...

    The delivered LHC integrated luminosity of more than 1 inverse femtobarn by summer and more than 5 by the end of 2011 has been a gold mine for the physics groups. With 2011 data, we have submitted or published 14 papers, 7 others are in collaboration-wide review, and 75 Physics Analysis Summaries have been approved already. They add to the 73 papers already published based on the 2010 and 2009 datasets. Highlights from each physics analysis group are described below. Heavy ions Many important results have been obtained from the first lead-ion collision run in 2010. The published measurements include the first ever indications of Υ excited state suppression (PRL synopsis), long-range correlation in PbPb, and track multiplicity over a wide η range. Preliminary results include the first ever measurement of isolated photons (showing no modification), J/ψ suppression including the separation of the non-prompt component, further study of jet fragmentation, nuclear modification factor...

      The period since the last CMS Bulletin has been historic for CMS Physics. The pinnacle of our physics programme was an observation of a new particle – a strong candidate for a Higgs boson – which has captured worldwide interest and made a profound impact on the very field of particle physics. At the time of the discovery announcement on 4 July, 2012, prominent signals were observed in the high-resolution H→γγ and H→ZZ(4l) modes. Corroborating excess was observed in the H→W+W– mode as well. The fermionic channel analyses (H→bb, H→ττ), however, yielded less than the Standard Model (SM) expectation. Collectively, the five channels established the signal with a significance of five standard deviations. With the exception of the diphoton channel, these analyses have all been updated in the last months and several new channels have been added. With improved analyses and more than twice the i...

    The collisions last year at 900 GeV and 2.36 TeV provided the long anticipated collider data to the CMS physics groups. Quite a lot has been accomplished in a very short time. Although the delivered luminosity was small, CMS was able to publish its first physics paper (with several more in preparation), and commence the commissioning of physics objects for future analyses. Many new performance results have been approved in advance of this CMS Week. One remarkable outcome has been the amazing agreement between out-of-the-box data with simulation at these low energies so early in the commissioning of the experiment. All of this is testament to the hard work and preparation conducted beforehand by many people in CMS. These analyses could not have happened without the dedicated work of the full collaboration on building and commissioning the detector, computing, and software systems combined with the tireless work of many to collect, calibrate and understand the data and our detector. To facilitate the efficien...

    The Physics Groups are actively engaged on analyses of the first data from the LHC at 7 TeV, targeting many results for the ICHEP conference taking place in Paris this summer. The first large batch of physics approvals is scheduled for this CMS Week, to be followed by four more weeks of approvals and analysis updates leading to the start of the conference in July. Several high priority analysis areas were organized into task forces to ensure sufficient coverage from the relevant detector, object, and analysis groups in the preparation of these analyses. Already some results on charged particle correlations and multiplicities in 7 TeV minimum bias collisions have been approved. Only one small detail remains before ICHEP: further integrated luminosity delivered by the LHC! Beyond the Standard Model measurements that can be done with these data, the focus changes to the search for new physics at the TeV scale and for the Higgs boson in the period after ICHEP. Particle Flow The PFT group is focusing on the ...

      2012 has started off as a very busy year for the CMS Physics Groups. Planning for the upcoming higher luminosity/higher energy (8 TeV) operation of the LHC and relatively early Rencontres de Moriond are the high-priority activities for the group at the moment. To be ready for the coming 8-TeV data, CMS has made a concerted effort to perform and publish analyses on the 5 fb−1 dataset recorded in 2011. This has resulted in the submission of 16 papers already, including nine on the search for the Higgs boson. In addition, a number of preliminary results on the 2011 dataset have been released to the public. The Exotica and SUSY groups approved several searches for new physics in January, such as searches for W′ and exotic highly ionising particles. These were highlighted at a CERN seminar given on 24th  January. Many more analyses, from all the PAGs, including the newly formed SMP (Standard Model Physics) and FSQ (Forward and Small-x QCD), were approved in February. The ...

    Physics-wise, the CMS week in December was dominated by discussions of the analyses that will be carried out in the “next six months”, i.e. while waiting for the first LHC collisions.  As presented in December, analysis approvals based on Monte Carlo simulation were re-opened, with the caveat that for this work to be helpful to the goals of CMS, it should be carried out using the new software (CMSSW_2_X) and associated samples.  By the end of the week, the goal for the physics groups was set to be the porting of our physics commissioning methods and plans, as well as the early analyses (based an integrated luminosity in the range 10-100pb-1) into this new software. Since December, the large data samples from CMSSW_2_1 were completed. A big effort by the production group gave a significant number of events over the end-of-year break – but also gave out the first samples with the fast simulation. Meanwhile, as mentioned in December, the arrival of 2_2 meant that ...

  3. Public Outreach of the South Texas Health Physic Society and Texas A and M University Nuclear Engineering Department

    International Nuclear Information System (INIS)

    In a cooperative effort of the members of the South Texas Chapter of the Heath Physics Society (STC-HPS) and the Texas A and M University Nuclear Engineering Department, great efforts have been made to reach out and provide educational opportunities to members of the general public, school age children, and specifically teachers. These efforts have taken the form of Science Teacher Workshops (STW), visits to schools all over the state of Texas, public forums, and many other educational arenas. A major motivational factor for these most recent efforts can be directly tied to the attempt of the State of Texas to site a low-level radioactive waste facility near Sierra Blanca in West Texas. When the State of Texas first proposed to site a low level radioactive waste site after the Low-Level Radioactive Waste Policy Act of 1980 was passed, many years of political struggle ensued. Finally, a site at Sierra Blanca in far West Texas was selected for study and characterization for a disposal site for waste generated in the Texas Compact states of Maine, Vermont and Texas. During this process, the outreach to and education of the local public became a paramount issue

    Since the last CMS Bulletin, the CMS Physics Analysis Groups have completed more than 70 new analyses, many of which are based on the complete Run 1 dataset. In parallel the Snowmass whitepaper on projected discovery potential of CMS for HL-LHC has been completed, while the ECFA HL-LHC future physics studies has been summarised in a report and nine published benchmark analyses. Run 1 summary studies on b-tag and jet identification, quark-gluon discrimination and boosted topologies have been documented in BTV-13-001 and JME-13-002/005/006, respectively. The new tracking alignment and performance papers are being prepared for submission as well. The Higgs analysis group produced several new results including the search for ttH with H decaying to ZZ, WW, ττ+bb (HIG-13-019/020) where an excess of ~2.5σ is observed in the like-sign di-muon channel, and new searches for high-mass Higgs bosons (HIG-13-022). Search for invisible Higgs decays have also been performed both using the associ...

    In the period since the last CMS Bulletin, the LHC – and CMS – have entered LS1. During this time, CMS Physics Analysis Groups have performed more than 40 new analyses, many of which are based on the complete 8 TeV dataset delivered by the LHC in 2012 (and in some cases on the full Run 1 dataset). These results were shown at, and well received by, several high-profile conferences in the spring of 2013, including the inaugural meeting of the Large Hadron Collider    Physics Conference (LHCP) in Barcelona, and the 26th International Symposium on Lepton Photon Interactions at High Energies (LP) in San Francisco. In parallel, there have been significant developments in preparations for Run 2 of the LHC and on “future physics” studies for both Phase 1 and Phase 2 upgrades of the CMS detector. The Higgs analysis group produced five new results for LHCP including a new H-to-bb search in VBF production (HIG-13-011), ttH with H to γ&ga...

    The period since the last CMS bulletin has seen the end of proton collisions at a centre-of-mass energy 8 TeV, a successful proton-lead collision run at 5 TeV/nucleon, as well as a “reference” proton run at 2.76 TeV. With these final LHC Run 1 datasets in hand, CMS Physics Analysis Groups have been busy analysing these data in preparation for the winter conferences. Moreover, despite the fact that the pp run only concluded in mid-December (and there was consequently less time to complete data analyses), CMS again made a strong showing at the Rencontres de Moriond in La Thuile (EW and QCD) where nearly 40 new results were presented. The highlight of these preliminary results was the eagerly anticipated updated studies of the properties of the Higgs boson discovered in July of last year. Meanwhile, preparations for Run 2 and physics performance studies for Phase 1 and Phase 2 upgrade scenarios are ongoing. The Higgs analysis group produced updated analyses on the full Run 1 dataset (~25 f...

    The Electroweak and Top Quark Workshop (16-17th of July) A Workshop on Electroweak and Top Quark Physics, dedicated on early measurements, took place on 16th-17th July. We had more than 40 presentations at the Workshop, which was an important milestone for 2007 physics analyses in the EWK and TOP areas. The Standard Model has been tested empirically by many previous experiments. Observables which are nowadays known with high precision will play a major role for data-based CMS calibrations. A typical example is the use of the Z to monitor electron and muon reconstruction in di-lepton inclusive samples. Another example is the use of the W mass as a constraint for di-jets in the kinematic fitting of top-quark events, providing information on the jet energy scale. The predictions of the Standard Model, for what concerns proton collisions at the LHC, are accurate to a level that the production of W/Z and top-quark events can be used as a powerful tool to commission our experiment. On the other hand the measure...

  8. Analysis of vegetation by the application of a physically-based atmospheric correction algorithm to OLI data: a case study of Leonessa Municipality, Italy

    Remote sensing techniques allow to estimate vegetation parameters related to large areas for forest health evaluation and biomass estimation. Moreover, the parametrization of specific indices such as Normalized Difference Vegetation Index (NDVI) allows to study biogeochemical cycles and radiative energy transfer processes between soil/vegetation and atmosphere. This paper focuses on the evaluation of vegetation cover analysis in Leonessa Municipality, Latium Region (Italy) by the use of 2015 Landsat 8 applying the OLI@CRI (OLI ATmospherically Corrected Reflectance Imagery) algorithm developed following the procedure described in Bassani et al. 2015. The OLI@CRI is based on 6SV radiative transfer model (Kotchenova et al., 2006) ables to simulate the radiative field in the atmosphere-earth coupled system. NDVI was derived from the OLI corrected image. This index, widely used for biomass estimation and vegetation analysis cover, considers the sensor channels falling in the near infrared and red spectral regions which are sensitive to chlorophyll absorption and cell structure. The retrieved product was then spatially resampled at MODIS image resolution and then validated by the NDVI of MODIS considered as reference. The physically-based OLI@CRI algorithm also provides the incident solar radiation at ground at the acquisition time by 6SV simulation. Thus, the OLI@CRI algorithm completes the remote sensing dataset required for a comprehensive analysis of the sub-regional biomass production by using data of the new generation remote sensing sensor and an atmospheric radiative transfer model. If the OLI@CRI algorithm is applied to a temporal series of OLI data, the influence of the solar radiation on the above-ground vegetation can be analysed as well as vegetation index variation.

  10. Missed connections: A case study of the social networks of physics doctoral students in a single department

    Gender disparity is an issue among the many science, technology, engineering, and mathematics (STEM) fields. Although many previous studies examine gender issues in STEM as an aggregate discipline, there are unique issues to each of the fields that are considered STEM fields. Some fields, such as physics, have fewer women graduating with degrees than other fields. This suggests that women's experiences vary by STEM field. The majority of previous research also examines gender and other disparities at either the nationwide or individual level. This project entailed social network analysis through survey and interview data to examine a single physics department's doctoral students in order to provide a comprehensive look at student social experiences. In addition to examining gender, other demographic variables were studied to see if the results are truly associated with gender; these variables include race/ethnicity, year in program, student type, relationship status, research type, undergraduate institute, and subfield. Data were examined to determine if there are relationships to social connections and outcome variables such as persistence in completing the degree and the time to degree. Data collected on faculty were used to rank faculty members; data such as h-indices and number of students graduate over the past 5 years were collected. Fifty-five (55) of 110 possible participants completed the survey; forty-three are male, and twelve are female. Twenty-eight of the fifty-five survey participants were interview; twenty-three are male, and five are female. Findings for peer networks include that peer networks are established during the first year and do not change drastically as one progresses in the program. Geographic location within the campus affects socializing with peers. Connections to fellow students are not necessarily reciprocated; the maximum percentage of reciprocated connections is 60%. The number of connections one has varies by network purpose

    The thermodynamics of the atmosphere is the subject of several chapters in most textbooks on dynamic meteorology, but there is no work in English to give the subject a specific and more extensive treatment. In writing the present textbook, we have tried to fill this rather remarkable gap in the literature related to atmospheric sciences. Our aim has been to provide students of meteorology with a book that can playa role similar to the textbooks on chemical thermodynamics for the chemists. This implies a previous knowledge of general thermodynamics, such as students acquire in general physics courses; therefore, although the basic principles are reviewed (in the first four chapters), they are only briefly discussed, and emphasis is laid on those topics that will be useful in later chapters, through their application to atmospheric problems. No attempt has been made to introduce the thermodynamics of irreversible processes; on the other hand, consideration of heterogeneous and open homogeneous systems permits a...

    The main programme of the Physics Week held between 16th and 20th May was a series of topology-oriented workshops on di-leptons, di-photons, inclusive W, and all-hadronic final states. The goal of these workshops was to reach a common understanding for the set of objects (ID, cleaning...), the handling of pile-up, calibration, efficiency and purity determination, as well as to revisit critical common issues such as the trigger. Di-lepton workshop Most analysis groups use a di-lepton trigger or a combination of single and di-lepton triggers in 2011. Some groups need to collect leptons with as low PT as possible with strong isolation and identification requirements as for Higgs into WW at low mass, others with intermediate PT values as in Drell-Yan studies, or high PT as in the Exotica group. Electron and muon reconstruction, identification and isolation, was extensively described in the workshop. For electrons, VBTF selection cuts for low PT and HEEP cuts for high PT were discussed, as well as more complex d...

  15. The Intercomparison of 3D Radiation Codes (I3RC): Showcasing Mathematical and Computational Physics in a Critical Atmospheric Application

    The Intercomparison of 3D Radiation Codes (I3RC) is an on-going initiative involving an international group of over 30 researchers engaged in the numerical modeling of three-dimensional radiative transfer as applied to clouds. Because of their strong variability and extreme opacity, clouds are indeed a major source of uncertainty in the Earth's local radiation budget (at GCM grid scales). Also 3D effects (at satellite pixel scales) invalidate the standard plane-parallel assumption made in the routine of cloud-property remote sensing at NASA and NOAA. Accordingly, the test-cases used in I3RC are based on inputs and outputs which relate to cloud effects in atmospheric heating rates and in real-world remote sensing geometries. The main objectives of I3RC are to (1) enable participants to improve their models, (2) publish results as a community, (3) archive source code, and (4) educate. We will survey the status of I3RC and its plans for the near future with a special emphasis on the mathematical models and computational approaches. We will also describe some of the prime applications of I3RC's efforts in climate models, cloud-resolving models, and remote-sensing observations of clouds, or that of the surface in their presence. In all these application areas, computational efficiency is the main concern and not accuracy. One of I3RC's main goals is to document the performance of as wide a variety as possible of three-dimensional radiative transfer models for a small but representative number of ``cases.'' However, it is dominated by modelers working at the level of linear transport theory (i.e., they solve the radiative transfer equation) and an overwhelming majority of these participants use slow-but-robust Monte Carlo techniques. This means that only a small portion of the efficiency vs. accuracy vs. flexibility domain is currently populated by I3RC participants. To balance this natural clustering the present authors have organized a systematic outreach towards

  16. A contribution to the study of the physical properties of natural and radioactive aerosols in controlled atmospheres

    International Nuclear Information System (INIS)

    The major objective of this work was to study the properties of normal and radioactive particles produced by attachment of radon 222 daughters on environmental aerosol particles, in various and controlled atmospheres. In the first part, devoted to the radioactivity of radon 222, the influence of the number of nuclei on the radioactive equilibrium state and the size distribution of alpha radioactivity was demonstrated. In the second part, an experimental study of the C.E.A. α dosimeter was developed. We investigated the counting and the collection efficiency of the dosimeter for inlet particles in the 0.001-0.1 μm size range. The last part concerns aerosol-filtration behaviour. The comparison between experimental and theoretical procedures revealed a good agreement only in some circumstances for membrane filters. In the case of fibrous filters the agreement is quite satisfactory. Particularly, if the fiber size distribution is taken into account in the theoretical model, it results in an improved estimation of the collection efficiency

    Full Text Available The properties of atmospheric aerosol particles in Marseille and Athens were investigated. The studies were performed in Marseille, France, during July 2002 and in Athens, Greece, during June 2003. The aerosol size distribution and the formation and growth rates of newly formed particles were characterized using Differential Mobility Particle Sizers. Hygroscopic properties were observed using a Hygroscopic Tandem Differential Mobility Analyzer setup. During both campaigns, the observations were performed at suburban, almost rural sites, and the sites can be considered to show general regional background behavior depending on the wind direction. At both sites there were clear pattern for both aerosol number concentration and hygroscopic properties. Nucleation mode number concentration increased during the morning hours indicating new particle formation, which was observed during more than 30% of the days. The observed formation rate was typically more than 1 cm−3 s−1, and the growth rate was between 1.2–9.9 nm h−1. Based on hygroscopicity measurements in Athens, the nucleation mode size increase was due to condensation of both water insoluble and water soluble material. However, during a period of less anthropogenic influence, the growth was to a larger extent due to water insoluble components. When urban pollution was more pronounced, growth due to condensation of water soluble material dominated.

    Pulsed corona discharges propagated in argon (or in argon with added water vapor) at atmospheric pressure on the interior surface of a 49 cm long quartz tube were investigated for the application of surface bio-decontamination. H2O molecule dissociation in the argon plasma generated reactive species (i.e. OH in ground and excited states) and UV emission, which both directly affected bacterial cells. In order to facilitate the evaluation of the contribution of UV radiation, a DNA damage repair defective bacterial strain, Escherichia coli DH-1, was used. Discharge characteristics, including propagation velocity and plasma temperature, were measured. Up to ~5.5 and ~5 log10 reductions were observed for E. coli DH-1 bacteria (from 106 initial load) exposed 2 cm and 44 cm away from the charged electrode, respectively, for a 20 min plasma treatment. The factors contributing to the observed bactericidal effect include desiccation, reactive oxygen species (OH) plus H2O2 accumulation in the liquid phase, and UV-B (and possibly VUV) emission in dry argon. The steady state temperature measured on the quartz tube wall did not exceeded 29 °C the contribution of heating, along with that of H2O2 accumulation, was estimated to be low. The effect of UV-B emission alone or in combination with the other stress factors of the plasma process was examined for different operating conditions.

How has the economic development impacted on ecosystem, environment, agriculture and regional climate in this region ? What are the mechanisms of the interactive processes and feedbacks? What will be the future changes under different development scenarios? These are questions of critical importance to sustain the rate of social and economic development. A Major Project, The Physical-Chemical Processes in the Lower Atmosphere and Their Interaction with the Ecological System over Yangtze Delta,as one of the Ninth Five-Year Major Programs (1996-2000) funded by the National Natural Science Foundation of China, NSFC, just focused on those questions. Under the leadership of Prof. Zhou Xiuji, academician of the Chinese Academy of Sciences this project has made significant achievements and great progress in answering the above questions.
