  • WARNER MUSIC GROUP GERMANY Raphael Gualazzi Happy Mistake
    Raphael Gualazzi Happy Mistake Raphael Gualazzi Happy Mistake VÖ: April ´14 (tba) “Ich bin ein Musikliebhaber”, antwortet der Sänger & Pianist (wie auch Produzent & Arrangeur) wenn man ihn zu seinem Stil befragt, der Jazz, Soul, Klassik und Popmusik vermischt. „Ich möchte keines der Genres aufgeben, das ich liebe, seit ich angefangen habe, Musik zu machen. Dieses Album ist eine Mixtur und die Summe aller meiner Leidenschaften.“ HAPPY MISTAKE wird niemanden überraschen, der die Karriere des transalpinen Musikers bereits seit einigen Jahren verfolgt. Die neuen Songs sind die würdigen Nachfolger jener Titel, die bei Raphael Gualazzis letztem Album „Reality And Fantasy“ für den großen Erfolg gesorgt haben und das weltweit über 100.000-mal verkauft wurde. Raphael Gualazzis natürliche Neigung zu Vielseitigkeit und sein Gespür für Melodien spiegelt sich in diesen eingängigen Songs sofort wieder. Doch dieses Mal ist alles noch ein wenig vollkommener. Durch Tourneen und Konzerte wurde Raphaels Songwriting ausgefeilter. So ist es in der Tat recht schwer, den einen „Top Song“ von seinem neuen Album auszuwählen. Im Gegensatz zu einem musikalischen Umfeld, dem Substanz fehlt, scheint der junge Künstler mit Anfang dreißig mühelos hervorragende Titel zu schreiben, betont durch sein intensives Pianospiel und seine raue Stimme. Wenn HAPPY MISTAKE mit seiner Unmittelbarkeit beeindruckt, dann daher, weil man das Album praktisch sofort begreift. Während der Aufnahmen teilte sich Raphael Gualazzi das Mikrophon mit der französischen Sängerin CAMILLE bei dem Titel “L’amie d’un italien” (Ein italienischer Freund), ein kabarettähnlicher Titel, subtil arrangiert von Vince Mendoza. Inspiriert von seiner Leidenschaft für Swing & Groove findet man auf dem Album passend zu Raphaels Percussion Rhythmen auch kraftvolle Bläsersektionen.

  • Martian Crater Morphology
    ANALYSIS OF THE DEPTH-DIAMETER RELATIONSHIP OF MARTIAN CRATERS A Capstone Experience Thesis Presented by Jared Howenstine Completion Date: May 2006 Approved By: Professor M. Darby Dyar, Astronomy Professor Christopher Condit, Geology Professor Judith Young, Astronomy Abstract Title: Analysis of the Depth-Diameter Relationship of Martian Craters Author: Jared Howenstine, Astronomy Approved By: Judith Young, Astronomy Approved By: M. Darby Dyar, Astronomy Approved By: Christopher Condit, Geology CE Type: Departmental Honors Project Using a gridded version of maritan topography with the computer program Gridview, this project studied the depth-diameter relationship of martian impact craters. The work encompasses 361 profiles of impacts with diameters larger than 15 kilometers and is a continuation of work that was started at the Lunar and Planetary Institute in Houston, Texas under the guidance of Dr. Walter S. Keifer. Using the most ‘pristine,’ or deepest craters in the data a depth-diameter relationship was determined: d = 0.610D 0.327 , where d is the depth of the crater and D is the diameter of the crater, both in kilometers. This relationship can then be used to estimate the theoretical depth of any impact radius, and therefore can be used to estimate the pristine shape of the crater. With a depth-diameter ratio for a particular crater, the measured depth can then be compared to this theoretical value and an estimate of the amount of material within the crater, or fill, can then be calculated. The data includes 140 named impact craters, 3 basins, and 218 other impacts. The named data encompasses all named impact structures of greater than 100 kilometers in diameter.

Data collected by the Sample Analysis at Mars (SAM) instrument on the Curiosity Rover can be integrated with Mars analog work in order to better understand the fixation and mobility of nitrogen on Mars, and thus its availability to putative biology. In particular, the relationship between nitrate and other soluble salts may help reveal the timing of nitrogen fixation and post-depositional behavior of nitrate on Mars. In addition, in situ measurements of nitrogen abundance and isotopic composition may be used to model atmospheric conditions on early Mars. Methods: The data presented are from analyses of solid Martian drilled and scooped samples by the Sam- ple Analysis at Mars (SAM) instrument suite on the Mars Science Laboratory (MSL) Curiosity Rover.

SMPs are defined such that they would be suffi- ciently long-lived so as to still exist in the cosmos either as Big Bang relics or secondary collision products, and sufficiently massive such that they are typically beyond the reach of any conceiv- able accelerator-based experiment. The discovery of SMPs would address a number of important questions in modern physics, such as the origin and composition of dark matter and the unifi- cation of the fundamental forces. This review outlines the scenarios predicting SMPs and the techniques used at non-collider experiments to look for SMPs in cosmic rays and bound in mat- ter. The limits so far obtained on the fluxes and matter densities of SMPs which possess various detection-relevant properties such as electric and magnetic charge are given.

Rudnick, Committee Chair December 2018 ACKNOWLEDGEMENTS I dedicate this dissertation to my mom and dad, Melissa Talbott and Dennis Greaney, who instilled a sense of curiosity and independence in me from an early age. From talking me through my first elementary school homework assignments that left me in tears, to sharing words of encouragement when grad school finances got tight (“When I was in grad school I just shared peanut butter with the dog at the end of the month when I ran out of money”), my mom and dad taught me the persistence and resilience needed to be successful in a PhD program. They have shaped me into the person I am today, and I truly could not have gotten to where I am without them. Similarly, I’ve treasured the support and comedic relief from my sister Sam throughout the years.

  • NO ONE KNOWS ABOUT US by Bridget Canning. a Creative Writing
    NO ONE KNOWS ABOUT US By Bridget Canning. A Creative Writing Thesis submitted to the School of Graduate Studies in partial fulfillment of the requirements for the degree of Masters of Arts in English (Creative Writing) Department of English, Memorial University of Newfoundland Abstract: No One Knows about Us is a collection of twelve contemporary short stories. As the title suggests, the characters in each story deal with secrets: relationships, longings, grudges, addictions, and trickery. For them, these secrets are simultaneously overwhelming and futile; their importance within their small worlds reflect a deeper feeling of insignificance in the greater scheme of life in a small city in a northern province hemmed on to the side of a continent. Here are a range of characters and situations set in St. John’s, Newfoundland and Labrador. The stories are mapped out in different areas of the city and move chronologically over a year, starting in fall and ending in late summer. They work together to create a small sample of life in modern-day St. John’s – one that is informed by the influences of history, economy, and weather. i Acknowledgements: This thesis would not have been accomplished without the help of the English department faculty at Memorial such as Robert Finley, Robert Chafe, and especially my thesis advisor, Lisa Moore. Thanks to the Graduate Society for their financial support. Thanks to Jonathan Weir, Deirdre Snook, and the members of the Naked Parade Writing Collective for their guidance and encouragement. ii Contents: 1. Seen, p. 1 2. With Glowing Hearts, p. 19 3.
