    As the U.S. government\u27s reach and responsibilities expand, it remains unclear exactly what, if any, input the general populations of Afghanistan, Iraq, or the United States have on government actions. The environmental needs of the two States have concerned the world enough that the United Nations Environment Program ( UNEP ) has published a detailed post-conflict report on Afghanistan ( Afghanistan PCA ) and a Desk Study of the environment in Iraq ( Iraq Desk Study ). There are four basic ways that citizens can attempt either to enjoin U.S. government environmental action abroad or compel the government to adhere to established regulations and agreements: (1) private citizen or NGO suit under U.S. federal law; (2) private citizen or NGO suit under international law or one seeking to compel compliance with a treaty or agreement that the United States is party to; (3) suit by a non-U.S. national against the United States under a recognized treaty or against a U.S. corporation under ATCA; or (4) a qui tam action alleging fraudulent or illegal action by a party that costs the United States financially

    Evaluation of a wind-tunnel gust response technique including correlations with analytical and flight test results

    Get PDF
    A wind tunnel technique for obtaining gust frequency response functions for use in predicting the response of flexible aircraft to atmospheric turbulence is evaluated. The tunnel test results for a dynamically scaled cable supported aeroelastic model are compared with analytical and flight data. The wind tunnel technique, which employs oscillating vanes in the tunnel throat section to generate a sinusoidally varying flow field around the model, was evaluated by use of a 1/30 scale model of the B-52E airplane. Correlation between the wind tunnel results, flight test results, and analytical predictions for response in the short period and wing first elastic modes of motion are presented

    Structures of an apo and a binary complex of an evolved archeal b family DNA polymerase capable of synthesising highly cy-dye labelled DNA

    Thermophilic DNA polymerases of the polB family are of great importance in biotechnological applications including high-fidelity PCR. Of particular interest is the relative promiscuity of engineered versions of the exo- form of polymerases from the Thermo- and Pyrococcales families towards non-canonical substrates, which enables key advances in Next-generation sequencing. Despite this there is a paucity of structural information to guide further engineering of this group of polymerases. Here we report two structures, of the apo form and of a binary complex of a previously described variant (E10) of Pyrococcus furiosus (Pfu) polymerase with an ability to fully replace dCTP with Cyanine dye-labeled dCTP (Cy3-dCTP or Cy5-dCTP) in PCR and synthesise highly fluorescent “CyDNA” densely decorated with cyanine dye heterocycles. The apo form of Pfu-E10 closely matches reported apo form structures of wild-type Pfu. In contrast, the binary complex (in the replicative state with a duplex DNA oligonucleotide) reveals a closing movement of the thumb domain, increasing the contact surface with the nascent DNA duplex strand. Modelling based on the binary complex suggests how bulky fluorophores may be accommodated during processive synthesis and has aided the identification of residues important for the synthesis of unnatural nucleic acid polymers

    Hearing Voices: Sound Art Practice in a Cross-Cultural Context

    Get PDF
    This dissertation is concerned primarily with the body of work which has emerged from the author's project with endangered click languages in the Kalahari Desert. It looks at the development of his sound art practice by tracing the work leading up to Hearing Voices and by discussing the directions it has taken since the completion of that project. It examines the dichotomy in contemporary (sound) art between work which deals with ethnic identity and otherness and work which does not and outlines the ways in which the author's practice attempts to bridge this gap. Detailed examination of the socio-linguistic context of his work with Khoisan languages leads to an investigation of the issues and ethical responsibilities of cross-cultural practice. Links between acoustic ecology and language ecology are explored and consideration given to the way Hearing Voices and other works explore the boundaries between language and music, documentary and abstraction. The possibilities for new relationships between sound and (still) image are assessed through the author's use of new flat speaker technology and through an examination of the differences in approach required for the various media used in the Hearing Voices project (installation, radiophonic work, CD-ROM and work for multi-channel concert diffusion). Finally, the roles each of these forms can play in research-led sound art projects are considered

    Sound propagation in and radiation from acoustically lined flow ducts: A comparison of experiment and theory

    Get PDF
    The results of an experimental and theoretical study of many of the fundamental details of sound propagation in hard wall and soft wall annular flow ducts are reported. The theory of sound propagation along such ducts and the theory for determining the complex radiation impedance of higher order modes of an annulus are outlined, and methods for generating acoustic duct modes are developed. The results of a detailed measurement program on propagation in rigid wall annular ducts with and without airflow through the duct are presented. Techniques are described for measuring cut-on frequencies, modal phase speed, and radial and annular mode shapes. The effects of flow velocity on cut-on frequencies and phase speed are measured. Comparisons are made with theoretical predictions for all of the effects studies. The two microphone method of impedance is used to measure the effects of flow on acoustic liners. A numerical study of sound propagation in annular ducts with one or both walls acoustically lined is presented

    Public Participation Organizations and Open Policy:A Constitutional Moment for British Democracy?

    Get PDF
    This article builds on work in Science and Technology Studies and cognate disciplines concerning the institutionalization of public engagement and participation practices. It describes and analyses ethnographic qualitative research into one “organization of participation,” the UK government–funded Sciencewise program. Sciencewise’s interactions with broader political developments are explored, including the emergence of “open policy” as a key policy object in the UK context. The article considers what the new imaginary of openness means for institutionalized forms of public participation in science policymaking, asking whether this is illustrative of a “constitutional moment” in relations between society and science policymaking

    Development of microstructure and crystallographic texture in a double-sided friction stir welded microalloyed steel

    Get PDF
    The evolution of microstructure and crystallographic texture has been investigated in double-sided friction stir welded microalloyed steel, using electron backscatter diffraction (EBSD). The microstructure analyses show that the centre of stirred zone reached a temperature between Ac1 – Ac3 during FSW, resulting in a dual phase austenitic/ ferritic microstructure. The temperatures in the thermo-mechanically affected zone and the overlapped area between the first and second weld pass did not exceed the Ac1. The shear generated by the rotation probe occurs in austenitic/ferritic phase field where the austenite portion of the microstructure is transformed to a bainitic ferrite, on cooling. Analysis of crystallographic textures with regard to shear flow lines generated by the probe tool, show the dominance of simple shear components across the whole weld. The austenite texture at Ac1 – Ac3 is dominated by the B{11 ̅2} and ¯B {1 ̅12 ̅ } simple shear texture components, where the bainite phase textures formed on cooling were inherited from the shear textures of the austenite phase with relatively strong variant selection. The ferrite portion of the stirred zone and the ferrites in the thermo-mechanically affected zones and the overlapped area underwent shear deformation with textures dominated by the D1{1 ̅1 ̅2} and D2{112 ̅ } simple shear texture components. The formation of ultra-fine equiaxed ferrite with submicron grain size has been observed in the overlapped area between the first and second weld pass. This is due to continuous dynamic strain-induced recrystallisation as a result of simultaneous severe shear deformation and drastic undercooling

    Industrial constructions of publics and public knowledge: a qualitative investigation of practice in the UK chemicals industry

    Get PDF
    This is a post print version of the article. The official published version can be obtained from the link below - © 2007 by SAGE PublicationsWhile the rhetoric of public engagement is increasingly commonplace within industry, there has been little research that examines how lay knowledge is conceptualized and whether it is really used within companies. Using the chemicals sector as an example, this paper explores how companies conceive of publics and "public knowledge," and how this relates to modes of engagement/communication with them. Drawing on qualitative empirical research in four companies, we demonstrate that the public for industry are primarily conceived as "consumers" and "neighbours," having concerns that should be allayed rather than as groups with knowledge meriting engagement. We conclude by highlighting the dissonance between current advocacy of engagement and the discourses and practices prevalent within industry, and highlight the need for more realistic strategies for industry/public engagement.Funding was received from the ESRC Science in Society Programme
