Patterson * Member of USNC/URSI Executive Committee iv DESCRIPTION OF THE INTERNATIONAL UNION OF RADIO SCIENCE The International Union of Radio Science is one of 18 world scientific unions organized under the International Council of Scientific Unions (!CSU). It is commonly designated as URS! (from its French name, Union Radio Scientifique Internationale). Its aims are (1) to promote the scientific study of radio communications, (2) to aid and organize radio research requiring cooperation on an international scale and to encourage the discussion and publication of the results, (3) to facilitate agreement upon common methods of measurement and the standardization of measuring instruments, and (4) to stimulate and to coordinate studies of the scientific aspects of telecommunications using electromagnetic waves, guided and unguided. The International Union itself is an organizational framework to aid in promoting these objectives. The actual technical work is largely done by the National. Committee in the various countries. The officers of the International Union are: President: Prof. A.L. Cullen (U.K.) Past President: Dr. A.P. Mitra (India) Vice Presidents: Dr. Ing. H.J. Albrecht (F.R.G.) R.L. Dowden (New Zealand) E.D. Jull (Canada) Prof. V. Zima (Czechoslovakia) Secretary-General J. van Bladel (Belgium) Honorary Presidents: G. Beynon (U.K.) H.G. Booker (U.S.A.) W. Dieminger (West Germany) I. Koga (Japan) J.A. Ratcliffe (U.K.) The Secretary-General's office and the headquarters of the organization are located at Avenue Albert Lancaster, 32, B-1180 Brussels, Belgium. The Union is supported by contributions (dues) from 38 member countries. Additional funds for symposia and other scientific activities of the Union are provided by !CSU from contributions received for this purpose from UNESCO. The International Union, as of the XXth General Assembly held in Washington, DC in August 1981, has nine bodies called Commissions for centralizing studies in the principal technical fields. V Every three years the International Union holds a meeting called the General Assembly. The next is the XXIIIrd, to be held in 1990. The Secretariat prepares and distributes the Proceedings of the General Assemblies. The International Union arranges international symposia on specific subjects pertaining to the work of one or several Commissions and also cooperates with other Unions in international symposia on subjects of joint interest. Radio is unique among the fields of scientific work in having a specific adaptability to large-scale international research programs, since many of the phenomena that must be studied are worldwide in extent and yet are in a measure subject to control by experimenters. Exploration of space and the extension of scientific observations to the space environment are dependent on radio for their research. One branch, radio astronomy, involves cosmic phenomena. URSI thus has a distinct field of usefulness in furnishing a meeting ground for the numerous workers in the manifold aspects of radio research; its meetings and committee activities furnish valuable means of promoting research through exchange of ideas.

The following subject areas are covered: oscilloscopes, calibration standards, coaxial cables, connectors and probes. 1 A-1 Tu-AM Al-2 TWO LAYER DIELECTRIC MICROS TRI PLINE 0920 STRUCTURE: Si02 ON Si AND GaAs ON Si MODELING AND MEASUREMENT R.A. Lawton Boulder Research Associates Boulder, Colorado 80303 The two-layer dielectric microstripline structure is a structure that has found use in a number of applications. Two examples are in pulse waveform filtering to generate a pulse waveform standard and in the use of high quality silicon substrates in the manufacture of gallium arsenide devices. This paper will describe the concept of reference waveform standards using the two-layer dielectric microstripline structure (R.A. Lawton, N.S. Nahman and J.M. Bigelow, IEEE Trans. I&M, IM-33, No. 3, 201-205, 1984) and the further modeling that has been recently completed. Scattering parameters are computed from the distributed element circuit model and compared with measured values over the frequency range from 90 MHz to 18 GHz for a microstripline made from a wafer with silicon dioxide on silicon.

E-mail: fi[email protected] (Received 30 July 2015; revision accepted 22 January 2016) Abstract–Previous estimates of the volatile contents of Martian basalts, and hence their source regions, ranged from nearly volatile-free through estimates similar to those found in terrestrial subduction zones. Here, we use the bulk chemistry of Martian meteorites, along with Martian apatite and amphibole chemistry, to constrain the volatile contents of the Martian interior. Our estimates show that the volatile content of the source region for the Martian meteorites is similar to the terrestrial Mid-Ocean-Ridge Mantle source. Chlorine is enriched compared with the depleted terrestrial mantle but is similar to the terrestrial enriched source region; fluorine is similar to the terrestrial primitive mantle; and water is consistent with the terrestrial mantle. Our results show that Martian magmas were not volatile saturated; had water/chlorine and water/fluorine ratios ~0.4–18; and are most similar, in terms of volatiles, to terrestrial MORBs. Presumably, there are variations in volatile content in the Martian interior as suggested by apatite compositions, but more bulk chemical data, especially for fluorine and water, are required to investigate these variations.

  • 1 Using Eletrodynamic Tethers to Perform Station
    USING ELETRODYNAMIC TETHERS TO PERFORM STATION-KEEPING MANEUVERS IN LEO SATELLITES Thais Carneiro Oliveira(1), and Antonio Fernando Bertachini de Almeida Prado(2) (1)(2) National Institute for Space Research (INPE), Av. dos Astronautas 1758 São José dos Campos – SP – Brazil ZIP code 12227-010,+55 12 32086000, [email protected] and [email protected] Abstract: This paper analyses the concept of using an electrodynamic tether to provide propulsion to a space system with an electric power supply and no fuel consumption. The present work is focused on orbit maintenance and on re-boost maneuvers for tethered satellite systems. The analyses of the results will be performed with the help of a practical tool called “Perturbation Integrals” and an orbit integrator that can include many external perturbations, like atmospheric drag, solar radiation pressure and luni-solar perturbation. Keywords: Electromagnetic Tether, Station-Keeping Maneuver, Orbital Maneuver, Tether Systems, Disturbing Forces. 1. Introduction Space tether is a promising and innovating field of study, and many articles, technical reports, books and even missions have used this concept through the recent decades. An overview of the space tethered flight tests missions includes the Gemini tether experiments, the OEDIPUS flights, the TSS-1 experiments, the SEDS flights, the PMG, TiPs, ATEx missions, etc [1-6]. This paper analyses the potential of using an electrodynamic tether to provide propulsion to a space system with an electric power supply and no fuel consumption. The present work is focused on orbit maintenance and re-boosts maneuvers for tethered satellite systems (TSS). This type of system consists of two or more satellites orbiting around a planet linked by a cable or a tether [7].

  • Insights Into the Recurrent Energetic Eruptions That Drive Awu Among the Deadliest Volcanoes on Earth
    Insights into the recurrent energetic eruptions that drive Awu among the deadliest volcanoes on earth Philipson Bani1, Kristianto2, Syegi Kunrat2, Devy Kamil Syahbana2 5 1- Laboratoire Magmas et Volcans, Université Blaise Pascal - CNRS -IRD, OPGC, Aubière, France. 2- Center for Volcanology and Geological Hazard Mitigation (CVGHM), Jl. Diponegoro No. 57, Bandung, Indonesia Correspondence to: Philipson Bani ([email protected]) 10 Abstract The little known Awu volcano (Sangihe island, Indonesia) is among the deadliest with a cumulative death toll of 11048. In less than 4 centuries, 18 eruptions were recorded, including two VEI-4 and three VEI-3 eruptions with worldwide impacts. The regional geodynamic setting is controlled by a divergent-double-subduction and an arc-arc collision. In that context, the slab stalls in the mantle, undergoes an increase of temperature and becomes prone to 15 melting, a process that sustained the magmatic supply. Awu also has the particularity to host alternatively and simultaneously a lava dome and a crater lake throughout its activity. The lava dome passively erupted through the crater lake and induced strong water evaporation from the crater. A conduit plug associated with this dome emplacement subsequently channeled the gas emission to the crater wall. However, with the lava dome cooling, the high annual rainfall eventually reconstituted the crater lake and created a hazardous situation on Awu. Indeed with a new magma 20 injection, rapid pressure buildup may pulverize the conduit plug and the lava dome, allowing lake water injection and subsequent explosive water-magma interaction. The past vigorous eruptions are likely induced by these phenomena, a possible scenario for the future events.
