    Description / Table of Contents: Ostracoda are microcrustaceans which are extremely useful indicator-organisms in petroleum, coal and aquifer exploration and for environmental impact studies. They live in all types of aquatic habitats and are common microfossils in all sediments, including marine, estuarine and freshwater deposits as well as shallow and deep water facies. The group ranges in geological age from Cambrian to recent. The International Symposia on Ostracoda serve to underline the variety of applications for these useful microorganisms. This book is the 11th in a series produced from the Symposia. It has 48 papers and 35 abstracts and is arranged thematically for Earth Sciences (Palaeozoic, Mesozoic, Cenozoic, Statistics) and Life Sciences (Genetics, Microchemistry, Limnology, Shallow Marine, Oceanography, Morphology). New methodologies and techniques in statistics and microchemistry are featured; the book is copiously illustrated, often with excellent scanning electron microscope figures; and there are many review articles which carry full sets of references. As the latest volume in its field, 'Ostracoda in the Earth and Life Sciences' is a valuable source of data for students in both disciplines as well as specialists in the theme areas listed above. In particular, it will attract professional geologists and palaeontologists, geological surveys, museums, limnologists, oceanographers, geneticists, geochemists, and university teaching departments in the earth and biological sciences.

    Mixture distributions fitted to instrument counts (1991)
    [S.l.] : American Institute of Physics (AIP)
    Review of Scientific Instruments 62 (1991), S. 1347-1352

    Notes: A technique for fitting mixture distributions to discrete and continuous instrument count data is presented. The use of the EM algorithm for performing maximum likelihood estimation is introduced and advantages over other methods are discussed. Equations are presented for fitting mixtures of Poisson distributions and mixtures of normal distributions. Examples of the fitting of these two types of mixture distribution are given, and it is shown how standard errors of the parameter estimates can be obtained from within the framework of the fitting process.

    Angular distributions of sputtered zirconium atoms (1993)
    College Park, Md. : American Institute of Physics (AIP)
    The Journal of Chemical Physics 98 (1993), S. 5887-5898 
    Details
    ISSN: 1089-7690

    Topics: Physics , Chemistry and Pharmacology
    Notes: Ion beams with energies in the range 1–2 keV are used to sputter neutral Zr atoms from a polycrystalline surface. Laser induced fluorescence detection is used to obtain angular distributions of sputtered neutrals as a function of ion impact direction, ion mass, ion energy, and spin–orbit state of the exiting atoms. About 40% of the sputtered atoms are excited. Angular distributions depend weakly on ion mass and energy. The angular distributions are fitted well by a modified form of the Roosendaal and Saunders model of sputtering.

    An instrument for measuring angular distribution of sputtered neutral atoms (1993)
    [S.l.] : American Institute of Physics (AIP)
    Review of Scientific Instruments 64 (1993), S. 452-459 
    Details
    ISSN: 1089-7623
    Source: AIP Digital Archive
    Topics: Physics , Electrical Engineering, Measurement and Control Technology
    Notes: An apparatus utilizing laser-induced fluorescence (LIF) has been developed to measure high-resolution angular distributions of sputtered neutral atoms. LIF provides sensitive detection, a feature necessary to monitor the low atomic fluxes inherent to angularly resolved sputtering measurements in the static sputtering regime. The apparatus incorporates a detector assembly which rotates about the sample in an ultrahigh vacuum (UHV) chamber, allowing a large range of angular measurements at different ion beam incidence angles. Laser light is brought to the detector in the UHV chamber via a single optical fiber and fluorescence photons exit the chamber via a fiber bundle. The optical fiber and fiber bundle are mounted in a fixed orientation on the detector, maintaining constant alignment as the assembly rotates. Angular resolution in the polar plane containing the incident ion beam and the surface normal is better than 3°. Angular resolution in the direction perpendicular to the polar plane is governed by the Doppler shift and is 0.028° for 3.2 eV atoms. Overall detection efficiency is estimated to be 5×10−9 counts per sputtered atom and 2×10−3 counts per atom entering the detection volume. Initial experiments using polycrystalline Zr to characterize the device are described.

    THE EFFECTS OF HEAVY DRESSINGS OF POTASH APPLIED TO THE SEEDBED OF A LEY COMPARED WITH ANNUAL DRESSINGS (1968)
    Oxford, UK : Blackwell Publishing Ltd
    Grass and forage science 23 (1968), S. 0 
    Details
    ISSN: 1365-2494
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Two experiments were established to compare the effect on the yield of continuously cut herbage of varying amounts of potassium fertilizer applied either in one large dose to the seedbed, or as 3 equal dressings applied to the seedbed and in the summer of the 2 following years. Responses in dry–matter yield were recorded up to the higher rates of potassium fertilizer applied. Establishment and yield in the first 12 months were improved by seedbed applications of up to 4 cwt/ac of muriate of potash (60% K2O). Although total yields over the whole period were similar, whether the potassium was applied to the seedbed only or in annual dressings, yields from “all–in–seedbed” dressings declined towards the end of the period. Soil analysis indicated that annual dressings left behind higher residues of K.

    THE EFFECT OF POTASSIUM ON ESTABLISHMENT AND SEEDLING VIGOUR (1965)

    Notes: A permanent pasture was ploughed, 5 rates of potassium were incorporated in the seed-bed and a timothy/white-clover seed mixture was sown direct without a companion crop. Plant counts were taken during the fourth week of establishment. The highest rate of potash increased the size and number of timothy/white-clover plants considerably, without altering the timothy/white-clover ratio. Half the plots were cut once during the seeding year and the other half twice. Increasing rates of K increased dry-matter yields, particularly on the plots cut 7 weeks after sowing. Botanical analysis in the following year showed that, under both cutting systems, increasing rates of K tended to increase the proportion of white clover and decrease that of unsown species.

    Selective dry etching of silicon with respect to germanium (1990)
    Woodbury, NY : American Institute of Physics (AIP)
    Applied Physics Letters 56 (1990), S. 1436-1438 
    Details
    ISSN: 1077-3118
    Source: AIP Digital Archive
    Topics: Physics
    Notes: We describe a plasma-based dry etching procedure which permits selective etching of Si over Ge with a Si/Ge etch rate ratio of over 70 and negligible etching of the Ge underlayer. This is achieved in a SF6/H2/CF4 gas mixture by the formation of a thin ((approximately-equal-to)3 nm) involatile etch stop layer on the Ge surface which consists of Ge-sulfide and carbonaceous material.

    Use of Cement Kilns in Managing Solid and Hazardous Wastes: Implementation in Australia (1994)
    Oxford, UK : Blackwell Publishing Ltd
    Water and environment journal 8 (1994), S. 0 
    Details
    ISSN: 1747-6593
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Energy, Environment Protection, Nuclear Power Engineering
    Notes: The use of cement kilns for managing solid and hazardous wastes is facilitated by the high temperature, long gas retention periods, natural alkaline environment, minimum amount of waste produced and high thermal capacity. The main benefits include energy recovery, conservation of fossil fuels, reduction in cement production costs and the use of already existing facilities.The test burns conducted in cement kilns worldwide have demonstrated very high destruction efficiencies for most stable organic compounds, with toxic contaminants barely above the background levels.There are several cement plants in the US and Europe presently using solid and hazardous wastes as supplementary fuel. The application of this technology in Australia has been ignored in the past. An international conference (Kilnburn‘92) on the role of cement kilns in waste management was held recently in Australia and has enhanced the implementation of this technology in Australia.
