Full surface examination of small spheres with a computer controlled scanning electron microscope

This report discusses a computer automated stage and Scanning Electron Microscopy (SEM) system for detecting defects in glass spheres for inertial confinement laser fusion experiments. This system detects submicron defects and permits inclusion of acceptable spheres in targets after examination. The stage used to examine and manipulate the spheres through 4..pi.. steradians is described. Primary image recording is made on a roster scanning video disc. The need for SEM stability and methods of achieving it are discussed

Men Are More Likely to Be Homeless Than Women

Gender has an impact on people with mental illnesses. Men are more likely to be homeless than women. More social support needs to be provided to members of both gendersYork's Knowledge Mobilization Unit provides services and funding for faculty, graduate students, and community organizations seeking to maximize the impact of academic research and expertise on public policy, social programming, and professional practice. It is supported by SSHRC and CIHR grants, and by the Office of the Vice-President Research & Innovation. [email protected] www.researchimpact.c

Understanding friendship and learning networks of international and host students using longitudinal Social Network Analysis

While the number of international students travelling abroad for higher education constantly increases, it has been recognised among educators that international students have difficulty adjusting to their host educational environment. Past research indicates that international students’ personal ties with other international, home and host students can influence their cross-cultural adjustment to their new environment. Drawing from cross-cultural, educational science and social network research, we conducted a longitudinal study using dynamic social network analyses into how 485 international and 107 host students build learning and work relationships at both bachelor and post-graduate level. Results indicate that students from different cultural backgrounds develop dissimilar co-national and international friendships and learning relationships over time. Additionally, in contrast to previous findings our MRQAP and multiple regression analyses indicate that social interactions among international and host students did not become more intertwined over time. However, active (mixed) group activities (temporarily) increase cross-cultural interaction, indicating that institutions can play an active role in improving cross-cultural adjustment

HI Narrow Line Absorption in Dark Clouds

We have used the Arecibo telescope to carry out an survey of 31 dark clouds in the Taurus/Perseus region for narrow absorption features in HI ($\lambda$ 21cm) and OH (1667 and 1665 MHz) emission. We detected HI narrow self--absorption (HINSA) in 77% of the clouds that we observed. HINSA and OH emission, observed simultaneously are remarkably well correlated. Spectrally, they have the same nonthermal line width and the same line centroid velocity. Spatially, they both peak at the optically--selected central position of each cloud, and both fall off toward the cloud edges. Sources with clear HINSA feature have also been observed in transitions of CO, \13co, \c18o, and CI. HINSA exhibits better correlation with molecular tracers than with CI. The line width of the absorption feature, together with analyses of the relevant radiative transfer provide upper limits to the kinetic temperature of the gas producing the HINSA. Some sources must have a temperature close to or lower than 10 K. The correlation of column densities and line widths of HINSA with those characteristics of molecular tracers suggest that a significant fraction of the atomic hydrogen is located in the cold, well--shielded portions of molecular clouds, and is mixed with the molecular gas. The average number density ratio [HI]/[\h2] is $1.5\times10^{-3}$. The inferred HI density appears consistent with but is slightly higher than the value expected in steady state equilibrium between formation of HI via cosmic ray destruction of H$_2$ and destruction via formation of H$_2$ on grain surfaces. The distribution and abundance of atomic hydrogen in molecular clouds is a critical test of dark cloud chemistry and structure, including the issues of grain surface reaction rates, PDRs, circulation, and turbulent diffusion.Comment: 40 pages, 10 figures, accepted by Ap

Upper Kellwasser carbon isotope excursion pre-dates the F–F boundary in the Upper Devonian Lennard shelf carbonate system, Canning Basin, Western Australia

Here we report four high-resolution carbon isotope records in addition to trace element data for the Frasnian–Famennian (F–F) boundary interval in the Lennard Shelf carbonate system of the Canning Basin, Western Australia. This region lacks the characteristic black shale horizons associated with the global Late Devonian Kellwasser extinction events, yet still exhibits a trend in carbon isotope character similar to what has been reported from elsewhere in the world (two positive δ13C excursions with ~3–4‰ amplitudes). Enrichments in select trace element ratios suggest that both excursions are related to periods of oxygen deprivation and perhaps increased biological productivity. Given the continuous and stratigraphically expanded nature of Lennard Shelf sections, together with high-density sampling constrained by both conodont biostratigraphy and magnetostratigraphy, we observe that the Upper Kellwasser isotope excursion (maximum δ13C values) and associated trace element enrichments occur distinctly lower than the F–F boundary level. These results have implications for the paleoenvironmental conditions leading up to the Late Devonian Mass Extinction in terms of ocean chemistry and circulation patterns. This data set allows for a rare, detailed look at the temporal relationship between the Kellwasser events and the F–F boundary and constrains the pattern of carbon isotope perturbations at the intra-zonal scale

Slow and fast diffusion in a lead sulphate gravity separation process

A model for the growth of lead sulphate particles in a gravity separation system from the crystal glassware industry is presented. The lead sulphate particles are an undesirable byproduct, and thus the model is used to ascertain the optimal system temperature configuration such that particle extraction is maximised. The model describes the evolution of a single, spherical particle due to the mass flux of lead particles from a surrounding acid solution. We divide the concentration field into two separate regions. Specifically, a relatively small boundary layer region around the particle is characterised by fast diffusion, and is thus considered quasistatic. In contrast, diffusion in the far-field is slower, and hence assumed to be time-dependent. The final system consisting of two nonlinear, coupled ordinary differential equations for the particle radius and lead concentration, is integrated numerically

Transnational connections, competences and identities: experiences of Chinese international students after their return ‘home’

International students constitute a substantial and growing mobile population globally. However, as yet, the experiences of returnees and the ways in which their overseas studies impact on their identity and professional and personal lives over time have been under-researched areas. In this article we employ concepts from theories of transnationalism as a framework for the analysis of the experiences of Chinese graduate returnees. The empirical basis for the article is a 20-month, two-stage, mixed-method study of 652 Chinese students who returned home for work on completion of their degrees in UK universities over the last 25+ years. Evidence suggests that their journeys of studying abroad and returning home are dynamic and interconnected transnational experiences. Such experiences are avenues for diverse social networks that reinforce a complex cosmopolitan identity and awareness. They are, also, avenues for transnational(ised) new competences, skills and worldviews, which are increasingly valued by the students themselves upon return home. Irrespective of differences in their demographics and backgrounds, studying and living abroad was perceived by most returnees in our research as a profound identity transformating experience. These new connections, competences and identities enabled them to view and live life with a new sense of self at ‘home’ and, as a result, function in ways that continued to distinguish themselves from those around them over time. The findings have implications for higher education institutions and agencies that are concerned with enhancing the quality of university internationalisation. They also have implications for a broadened empirical and conceptual understanding of transnationalism
