Glossary Glossary
Glossary Glossary Albedo A measure of an object’s reflectivity. A pure white reflecting surface has an albedo of 1.0 (100%). A pitch-black, nonreflecting surface has an albedo of 0.0. The Moon is a fairly dark object with a combined albedo of 0.07 (reflecting 7% of the sunlight that falls upon it). The albedo range of the lunar maria is between 0.05 and 0.08. The brighter highlands have an albedo range from 0.09 to 0.15. Anorthosite Rocks rich in the mineral feldspar, making up much of the Moon’s bright highland regions. Aperture The diameter of a telescope’s objective lens or primary mirror. Apogee The point in the Moon’s orbit where it is furthest from the Earth. At apogee, the Moon can reach a maximum distance of 406,700 km from the Earth. Apollo The manned lunar program of the United States. Between July 1969 and December 1972, six Apollo missions landed on the Moon, allowing a total of 12 astronauts to explore its surface. Asteroid A minor planet. A large solid body of rock in orbit around the Sun. Banded crater A crater that displays dusky linear tracts on its inner walls and/or floor. 250 Basalt A dark, fine-grained volcanic rock, low in silicon, with a low viscosity. Basaltic material fills many of the Moon’s major basins, especially on the near side. Glossary Basin A very large circular impact structure (usually comprising multiple concentric rings) that usually displays some degree of flooding with lava. The largest and most conspicuous lava- flooded basins on the Moon are found on the near side, and most are filled to their outer edges with mare basalts. -

James Boerio i ABSTRACT Plasma processes, including plasma etching and plasma polymerization, were investigated for the pretreatment of aluminum prior to structural adhesive bonding. Since native oxides of aluminum are unstable in the presence of moisture at elevated temperature, surface engineering processes must usually be applied to aluminum prior to adhesive bonding to produce oxides that are stable. Plasma processes are attractive for surface engineering since they take place in the gas phase and do not produce effluents that are difficult to dispose off. Reactive species that are generated in plasmas have relatively short lifetimes and form inert products. -

Item Specifications High School Osas Science Test
ITEM SPECIFICATIONS HIGH SCHOOL OSAS SCIENCE TEST 2014 Oregon Science Standards (NGSS) Introduction This document presents item specifications for use with the Next Generation Science Standards (NGSS). These standards are based on the Framework for K-12 Science Education. The present document is not intended to replace the standards, but rather to present guidelines for the development of items and item clusters used to measure those standards. The remainder of this section provides a very brief introduction to the standards and the framework, an overview of the design and intent of the item clusters, and a description of specifications that follow. The bulk of the document is composed of specifications, organized by grade and standard. Background on the framework and standards The Framework for K-12 Science Education is organized around three core dimensions of scientific understanding. The standards are derived from these same dimensions: Disciplinary Core Ideas The fundamental ideas that are necessary for understanding a given science discipline. The core ideas all have broad importance within or across science or engineering disciplines, provide a key tool for understanding or investigating complex ideas and solving problems, relate to societal or personal concerns, and can be taught over multiple grade levels at progressive levels of depth and complexity. Science and Engineering Practices The practices are what students do to make sense of phenomena. They are both a set of skills and a set of knowledge to be internalized. The SEPs (Science and Engineering Practices) reflect the major practices that scientists and engineers use to investigate the world and design and build systems. -

EDRS PRICE MF-$O.75 HC-$9.00 PLUS POSTAGE DESCRIPTORS Aerospace Education; *Astronomy; *Curriculum Guides; *Earth Science; Geology; Laboratory Experiments; Oceanology; Science Activities; Science Education; *Secondary School Science IDENTIFIERS Pennsylvania ABSTRACT Designed for use in Pennsylvania secondary school science classes, this guide is intended to provide fundamental information in each of the various disciplines of the earth sciences. Some of the material contained in the guide is intended as background material for teachers. Five units are presented: The Earth, The Oceans, The Space Environment, The Atmosphere, and The Exploration of Space. The course is organized so that students proceed from the familiar, everyday world to the atmosphere and the space environment. Teaching geology in the fall takes advantage of weather conditions which permit field study. The purpose of the Earth and Space Science course is to encourage student behaviors which will be indicative of a broad understanding of man1s physical environment of earth and space as well as an awareness of the consequences which could result from changes which man may effect.(PEB) BEST COPY AVAILABLE U S DEPARTMENT OF HEALTH.

The Royal Society of Chemistry Presidents 1841 T0 2021
The Presidents of the Chemical Society & Royal Society of Chemistry (1841–2024) Contents Introduction 04 Chemical Society Presidents (1841–1980) 07 Royal Society of Chemistry Presidents (1980–2024) 34 Researching Past Presidents 45 Presidents by Date 47 Cover images (left to right): Professor Thomas Graham; Sir Ewart Ray Herbert Jones; Professor Lesley Yellowlees; The President’s Badge of Office Introduction On Tuesday 23 February 1841, a meeting was convened by Robert Warington that resolved to form a society of members interested in the advancement of chemistry. On 30 March, the 77 men who’d already leant their support met at what would be the Chemical Society’s first official meeting; at that meeting, Thomas Graham was unanimously elected to be the Society’s first president. The other main decision made at the 30 March meeting was on the system by which the Chemical Society would be organised: “That the ordinary members shall elect out of their own body, by ballot, a President, four Vice-Presidents, a Treasurer, two Secretaries, and a Council of twelve, four of Introduction whom may be non-resident, by whom the business of the Society shall be conducted.” At the first Annual General Meeting the following year, in March 1842, the Bye Laws were formally enshrined, and the ‘Duty of the President’ was stated: “To preside at all Meetings of the Society and Council. To take the Chair at all ordinary Meetings of the Society, at eight o’clock precisely, and to regulate the order of the proceedings. A Member shall not be eligible as President of the Society for more than two years in succession, but shall be re-eligible after the lapse of one year.” Little has changed in the way presidents are elected; they still have to be a member of the Society and are elected by other members. -

The Life and Death of Professor Alexander P. Borodin: Surgeon, Chemist, and Great Musician
Original communications The life and death of Professor Alexander P. Borodin: Surgeon, chemist, and great musician Igor E. Konstantinov, MD, Charlotte, N.C. From the Department of Thoracic and Cardiovascular Surgery, Carolinas Heart Institute, Charlotte, N.C. Music is one of the most effective and most beautiful means of communication between peoples. However characteristical- ly national the music may be, it will penetrate to the hearts of all receptive listeners regardless of outlook, provided that it has real beauty.1 SEVERAL EMINENT COMPOSERS HAVE flirted with the art of medicine. Hector Berlioz studied medicine in Paris.2,3 Franz von Suppe attended medical school for 1 year before settling down to the more serious work of composing frothy operettas.2 On the other hand, many physicians became more or less proficient in music.4 Perhaps the most promi- nent of them was Theodor Billroth, who became a pianist of high standing.5-7 His lifelong friendship with the famous composer Johannes Brahms, who dedicated his String Quartet, opus 51, to Billroth, is well known.6,7 The two Opus 51 quartets in C minor and A minor have come to be known by musically inclined surgeons as the Billroth I and II.6 However, life is such that very often one thing must be sacrificed in favor of another. For instance, Billroth once invited Brahms to listen to an ama- teur orchestra of physicians. After a few minutes, Brahms stood up and rushed away saying, “No, no, no! I would rather give the Vienna Philharmonic Orchestra to operate on me!” Professor Alexander Borodin combined the roles of medical doctor, chemist, and composer of major rank.8-17 It was my good fortune to study at the Military Fig. -
