Apollo Spacecraft Integrated Checkout Planning

The Apollo pa^loads, Command Module, Service Module, and Lunar Excursion Module require long range integrated checkout planning to assure mutual checkout compatibility and launch vehicle/spacecraft checkout compatibility. This function, performed in support of NASA\u27s Checkout and Test Division of the Manned Spacecraft Center, provides integrated checkout planning on an inter-center and intercontractor level. The end product results in NASA approved checkout flows and activities, in conjunction with their related ground support equipment, which delineate optimized prelaunch checkout operations and requirements. This presentation describes some of the aspects of the integrated checkout planning activity and gives examples of benefits derived from this task

Polarized Neutron Inelastic Scattering Study of the Anisotropic Magnetic Fluctuations in the Quasi-1D Ising-like Antiferromagnet TlCoCl3_3

Polarized neutron inelastic scattering experiments have been carried out in the quasi-1D Ising-like antiferromagnet TlCoCl$_3$. We observed the longitudinal magnetic fluctuation $S_{zz} (Q, \omega)$ for the spin-wave excitation continuum, which has not been observed in the unpolarized neutron inelastic scattering experiments of the quasi-1D Ising-like antiferromagnets CsCoCl$_3$ and TlCoCl$_3$ so far, together with the transverse magnetic fluctuation $S_{xx} (Q, \omega)$. We compared both obtained intensities of $S_{xx} (Q, \omega)$ and $S_{zz} (Q, \omega)$ with the perturbation theory from the pure Ising limit by Ishimura and Shiba, and a semi-quantitative agreement was found.Comment: 5 pages, 5 figures, jpsj2.cls, to be published in J.

The phase diagram of the lattice Calogero-Sutherland model

We introduce a {\it lattice} version of the Calogero Sutherland model adapted to describe $1/d^2$ pairwise interacting steps with discrete positions on a vicinal surface. The configurational free energy is obtained within a transfer matrix method. The full phase diagram for attractive and for repulsive interaction is deduced. For attraction, critical temperatures of faceting transitions are found to depend on step density.Comment: latex PRBCalogSuth.tex, 6 files, 4 pages [SPEC-S00/900

Occupational (Im)mobility in the Global Care Economy: The Case of Foreign-Trained Nurses in the Canadian Context

The twenty-first century has witnessed a number of significant demographic and political shifts that have resulted in a care crisis. Addressing the deficit of care provision has led many nations to actively recruit migrant care labour, often under temporary forms of migration. The emergence of this phenomenon has resulted in a rich field of analysis using the lens of care, including the idea of the Global Care Chain. Revisions to this conceptualization have pushed for its extension beyond domestic workers in the home to include skilled workers in other institutional settings, particularly nurses in hospitals and long-term care settings. Reviewing relevant literature on migrant nurses, this article explores the labour market experiences of internationally educated nurses in Canada. The article reviews research on the barriers facing migrant nurses as they transfer their credentials to the Canadian context. Analysis of this literature suggests that internationally trained nurses experience a form of occupational (im)mobility, paradoxical, ambiguous and contingent processes that exploit global mobility, and results in the stratified incorporation of skilled migrant women into healthcare workplaces
