Guide to the US collection of antarctic meteorites 1976-1988 (everything you wanted to know about the meteorite collection). Antarctic Meteorite Newsletter, Volume 13, Number 1

The state of the collection of Antarctic Meteorites is summarized. This guide is intended to assist investigators plan their meteorite research and select and request samples. Useful information is presented for all classified meteorites from 1976 to 1988 collections, as of Sept. 1989. The meteorite collection has grown over 13 years to include 4264 samples of which 2754 have been classified. Most of the unclassified meteorites are ordinary chondrites because the collections have been culled for specimens of special petrologic type. The guide consists of two large classification tables. They are preceded by a list of sample locations and important notes to make the tables understandable

Antarctic meteorite descriptions, 1980

Specimens found in the Alan Hills area include 361 ordinary chondrites, 4 carbonaceous chondrites, 6 achondrites, and 2 irons. Thirteen specimens measured over 11 cm in diameter and 69 between 5 to 10 cm in diameter are reported. The remainder of the finds were small, and many were paired. One of the irons was estimated to weigh about 20 kilograms

The development and impact of campaigning journalism in Britain, 1840-1875 : the old new journalism?

This thesis examines the development of campaigning writing in newspapers and periodicals between 1840 and 1875 and its relationship to concepts of Old and New Journalism. Campaigning is often regarded as characteristic of the New Journalism of the fin de siècle, particularly in the form associated with W. T. Stead at the Pall Mall Gazette in the 1880s. New Journalism was persuasive, opinionated, and sensational. It displayed characteristics of the American mass-circulation press, including eye-catching headlines on newspaper front pages. The period covered by this thesis begins in 1840, with the Chartist Northern Star as the hub of a campaign on behalf of the leaders of the Newport rising of November 1839. It ends in 1875, on the cusp of the New Journalism, a year before Stead published his reports condemning Turkish atrocities in Bulgaria in the regional daily, the Northern Echo. I argue that characteristics of New Journalism, such as persuasive writing and sensational revelations, were evident before 1875, particularly in the development of campaigning journalism in this period. Chapter 1 examines the context and definitions of campaigning journalism in relation to Old and New Journalism. Chapter 2 focuses on the genre of investigative writing, examining techniques such as interviewing and undercover reporting and their impact on New Journalism. Chapter 3 considers ways in which campaigning ideas were communicated through networks. Chapter 4 interrogates concepts of ‘popular’, ‘radical’, and ‘commercial’ by analysing three popular Sunday newspapers — the News of the World, Lloyd’s Weekly News, and Reynolds’s Newspaper — and their selection of campaigns. Chapter 5 examines how the press presented the second phase of the movement to repeal the ‘Taxes on Knowledge’, between 1849 and 1869, a campaign that was directly relevant to the economic and regulatory framework in which books, newspapers, and periodicals were produced

Antarctic meteorite descriptions 1976-1977-1978-1979

All previously distributed meteorite data sheets, plus a number of new ones for 1979 chondrites are included. A comprehensive sample index listing meteorite name/number, classification, and weathering category is also included. Separate indexes listing all petrologic type 3 and type 4 chondrites, all irons, all achondrites, and all carbonaceous chondrites in the collection is provided

On Using Magnetic and optical methods to determine the size and characteristics of nanoparticles embedded in oxide semiconductors

Films of oxides doped with transition metals are frequently believed to have magnetic inclusions. Magnetic methods to determine the amount of nanophases and their magnetic characteristics are described. The amount of the sample that is paramagnetic may also be measured. Optical methods are described and shown to be very powerful to determine which defects are also magnetic.Comment: Manuscript of poster to be presented at MMM-Intermag 2010.

Spin polarized transport current in n-type co-doped ZnO thin films measured by Andreev spectroscopy

We use point contact Andreev reflection measurements to determine the spin polarization of the transport current in pulse laser deposited thin films of ZnO with 1% Al and with and without 2%Mn. Only films with Mn are ferromagnetic and show spin polarization of the transport current of up to 55 $\pm$ 0.5% at 4.2 K, in sharp contrast to measurements of the nonmagnetic films without Mn where the polarization is consistent with zero. Our results imply strongly that ferromagnetism in these Al doped ZnO films requires the presence of Mn.Comment: Published versio
