Crystalline Silica, Cristobalite (CAS No
Crystalline Silica, Quartz (CAS No. 14808-60-7) Crystalline Silica, Cristobalite (CAS No. 14464-46-1) Crystalline Silica, Tridymite (CAS No. 15468-32-3) Diatomaceous earth (CAS No. 61790-53-2) This dossier on crystalline silica, quartz, cristobalite and tridymite and diatomaceous earth presents the most critical studies pertinent to the risk assessment of these substances in their use in drilling muds and cement additives. This dossier does not represent an exhaustive or critical review of all available data. The majority of information presented in this dossier was obtained from the ECHA database that provides information on chemicals that have been registered under the EU REACH (ECHA). Where possible, study quality was evaluated using the Klimisch scoring system (Klimisch et al., 1997). For the purpose of this dossier, crystalline silica, quartz (CAS No. 14808-60-7) has been reviewed as representative of crystalline silica cristobalite and tridymite. Crystalline silica, quartz is also considered representative of diatomaceous earth, as they both consist mainly of silicon dioxide. Screening Assessment Conclusion – Crystalline silica, quartz, cristobalite and tridymite and diatomaceous earth are classified as tier 1 chemicals and require a hazard assessment only. 1 BACKGROUND Crystalline silica is a common mineral found in the earth's crust. Materials like sand, stone, concrete and mortar contain crystalline silica. It is also used to make products such as glass, pottery, ceramics, bricks and artificial stone. Silica, in the form of sand, is used as the main ingredient in sand casting for the manufacture of metallic components in engineering and other applications. The high melting point of silica enables it to be used in such applications. -
Minnesota's Mineral Resources
CHAPTER • 9 Minnesota's Mineral Resources IN MINNESOTA the production of iron ore is far more valuable economically than the total of all other mineral products, but im portant industries are based on Minnesota's other geological forma tions as well. Architectural, monumental, and structural stone are produced from granite, limestone, dolomite, and other Minnesota rocks. Gravel and sand are excavated and processed, and clay is used for many ceramic products. :Manganese in important amounts occurs in the iron ores of the Cuyuna district. Finally, although they are often not thought of as mineral products, two of our most im portant mineral resources are water and soil. The iron ores and mining operations of the Mesabi, Vermilion, and Cuyuna iron-bearing districts and of the southeastern lYlinnesota counties will be discussed in detail in later chapters, but a few sta tistics on Minnesota's iron ore industry may remind us how impor tant this geological heritage is. The following is an estimate of Min nesota's iron ore reserves, made on lYlay 1, 1961: Gross Tons Mesabi Range 500,799,179 Vermilion Range 9,755,974 Cuyuna Range 36,530,000 Fillmore County 'il,860,337 Total iron ore 549,945,490 172 MI NESOTA'S MINERAL RESOURCES The total production of iron ore in Minne ota to January 1, 1962, was 2,529,737,553 tons. Total taxes paid on iron ore to January 1, 1961 , were approximately $1,257,448,400, a very important source of funds for the state government. Slightly over 60 per cent of the total iron ore produced in the United States has come from l\1inne- ota. -
The New IMA List of Gem Materials – a Work in Progress – Updated: July 2018
The New IMA List of Gem Materials – A Work in Progress – Updated: July 2018 In the following pages of this document a comprehensive list of gem materials is presented. The list is distributed (for terms and conditions see below) via the web site of the Commission on Gem Materials of the International Mineralogical Association. The list will be updated on a regular basis. Mineral names and formulae are from the IMA List of Minerals: http://nrmima.nrm.se//IMA_Master_List_%282016-07%29.pdf. Where there is a discrepancy the IMA List of Minerals will take precedence. Explanation of column headings: IMA status: A = approved (it applies to minerals approved after the establishment of the IMA in 1958); G = grandfathered (it applies to minerals discovered before the birth of IMA, and generally considered as valid species); Rd = redefined (it applies to existing minerals which were redefined during the IMA era); Rn = renamed (it applies to existing minerals which were renamed during the IMA era); Q = questionable (it applies to poorly characterized minerals, whose validity could be doubtful). Gem material name: minerals are normal text; non-minerals are bold; rocks are all caps; organics and glasses are italicized. Caveat (IMPORTANT): inevitably there will be mistakes in a list of this type. We will be grateful to all those who will point out errors of any kind, including typos. Please email your corrections to [email protected]. Acknowledgments: The following persons, listed in alphabetic order, gave their contribution to the building and the update of the IMA List of Minerals: Vladimir Bermanec, Emmanuel Fritsch, Lee A. -
The Globalization of K-Pop: the Interplay of External and Internal Forces
THE GLOBALIZATION OF K-POP: THE INTERPLAY OF EXTERNAL AND INTERNAL FORCES Master Thesis presented by Hiu Yan Kong Furtwangen University MBA WS14/16 Matriculation Number 249536 May, 2016 Sworn Statement I hereby solemnly declare on my oath that the work presented has been carried out by me alone without any form of illicit assistance. All sources used have been fully quoted. (Signature, Date) Abstract This thesis aims to provide a comprehensive and systematic analysis about the growing popularity of Korean pop music (K-pop) worldwide in recent years. On one hand, the international expansion of K-pop can be understood as a result of the strategic planning and business execution that are created and carried out by the entertainment agencies. On the other hand, external circumstances such as the rise of social media also create a wide array of opportunities for K-pop to broaden its global appeal. The research explores the ways how the interplay between external circumstances and organizational strategies has jointly contributed to the global circulation of K-pop. The research starts with providing a general descriptive overview of K-pop. Following that, quantitative methods are applied to measure and assess the international recognition and global spread of K-pop. Next, a systematic approach is used to identify and analyze factors and forces that have important influences and implications on K-pop’s globalization. The analysis is carried out based on three levels of business environment which are macro, operating, and internal level. PEST analysis is applied to identify critical macro-environmental factors including political, economic, socio-cultural, and technological. -

Thank You, Shaun Shelton, for a Very Informative Program on Cleaning Specimens with an Impressive Array of Minerals Displayed
Volume 57 Number 8 August 1, 2016 From Da Prez: Thank you, Shaun Shelton, for a very informative program on cleaning specimens with an impressive array of minerals displayed. We learned a lot, even who is ready with a short joke once asked! A large group of 11 travelled to Marshall, NC for the month’s field trip to Little Pine Garnet Mine. I believe it was about 6 degrees cooler there at 90 degrees, and even cooler inside the mine, of course. The mine has changed and weathered considerably in the last few years. Digging in the creek bank proved to be the most productive as Steve Smith and Mike Smagner found. At least they gave us a group discount rate. Unless more of the mine is opened up, I don’t know that it will be cost effective as a destination, but always good to get outdoors and find a few specimens. We hope many of you can make it for the Grassy Creek Show and to Crabtree Mine while in the area of Little Switzerland and Spruce Pine. [ The] August meeting will offer a rare look into the history of the club, offered by Joe Maguire [Gary Parker, Ed Deckert, Joyce Patton, Steve Smith, John Hiller, Mary Pendergraph, and others.] See you soon!

It is a Gryphon Gryphette. It was originally designed to put the grooves in glass when working stained glass. This machine was purchased from eBay. Machine, 2 grooving grind- ers, and shipping costs totaled about $100. Grooving machine This is the grooving cutter/grinder currently mounted on the Gryphon Gryphette machine shown on previous photo. Diamond coating on edge of cutter/grinder Set screw You’re ready to start making your pendant. The first thing to do is select a stone. Pick a good quality cabo- chon. The purpose of wire wrapping is to showcase the stone, not necessarily the wire. A quality stone wrap always begins with a quality stone. This stone is dendritic jasper from Burro Creek, AZ. Use a soft touch. Hold stone with flat side down and turn on grooving machine to make the groove. It is best to make 4 to 6 passes around the stone to prevent chipping and prevent diamond from “wiping” off the diamond-coated grinding wheel. Woof!

The Origins of Color in Minerals Four Distinct Physical Theories
American Mineralogist, Volume 63. pages 219-229, 1978 The origins of color in minerals KURT NASSAU Bell Laboratories Murray Hill, New Jersey 07974 Abstract Four formalisms are outlined. Crystal field theory explains the color as well as the fluores- cence in transition-metal-containing minerals such as azurite and ruby. The trap concept, as part of crystal field theory, explains the varying stability of electron and hole color centers with respect to light or heat bleaching, as well as phenomena such as thermoluminescence. The molecular orbital formalism explains the color of charge transfer minerals such as blue sapphire and crocoite involving metals, as well as the nonmetal-involving colors in lazurite, graphite and organically colored minerals. Band theory explains the colors of metallic minerals; the color range black-red-orange- yellow-colorless in minerals such as galena, proustite, greenockite, diamond, as well as the impurity-caused yellow and blue colors in diamond. Lastly, there are the well-known pseudo- chromatic colors explained by physical optics involving dispersion, scattering, interference, and diffraction.

THE RELATION OF ST. PAUL'S ETHICS TO HIS DOCTRINE OF SALVATION BY H. W. KSRLEY, B.A., B.D. A THESIS PRESENTED TO THE FACULTY OF DIVINITY OF THE UNIVERSITY OF EDINBURGH FOR THE DEGREE OF PH.D. THE RELATION OF ST. PAUL'S ETHICS TO HIS DOCTRINE OF SALVATION CONTENTS Page CHAPTER ONE INTRODUCTION................................ 1 CHAPTER TWO CONVERSION AND BACKGROUND................... 10 CHAPTER THREE THE DOCTRINE OF "IN CHRIST1"................. 60 CHAPTER FOUR THE NATURE OF: REDEMPTION.................... 106 CHAPTER FIVE THE NATURE OF JUSTIFICATION................. 145 CHAPTER SIX THE NATURE OF RECONCILIATION................ 182 CHAPTER SEVEN THE LIFE OF HOLINESS........................ £14 CHAPTER EIGHT ETHICAL PRESUPPOSITIONS..................... 248 CHAPTER ONE INTRODUCTION In the epistles of St. Paul we find a remarkably well- developed theology. Ethical teaching is, however, by no means lacking. A brief survey is sufficient to show that a large proportion of his extant writings is devoted to practical advice and exhortation. Frequently the main body of ethical teaching follows the section in which his theology is developed and explained. Sometimes, as in the epistle to the Romans, the transition seems to be abrupt and the connection obscure. Possibly it is for this reason that there has been, at times, a tendency either to emphasize the doctrine or the ethic to the exclusion of the other, or to give more or less equal weight to both, and thus to emphasize the disconnection between the two. Some ages have taken St. Paul's doctrine without his ethic. Our own seems to be more concerned with ethics than with theology, and the attempt is made to establish morality without a doctrinal basis.
