Abstract:
This dissertation presents an investigation on the effects of large scale roughness on the properties of giant magnetoresistive multilayers. The large scale roughness (sigmarms > 5 nm) is introduced into giant magnetoresistive thin films through the substrate. Current-in-plane (CIP) and current-perpendicular-to-the-plane (CPP) thin films were deposited by dc magnetron and triode sputtering. All films were characterized for roughness, magnetic and electronic behavior.;Our research on both pseudo spin valves and exchange-biased spin valves shows that long length scale roughness does not have a s

Abstract:
The process of mass-loss from evolved stars is the single largest contributor of matter back into the ISM. Intense mass-loss during the AGB phase of low-intermediate mass stars via a radiatively-driven wind can lead the stars to become enshrouded in an optically-thick layer of dust which condenses out of an extended molecular atmosphere. This thesis attempts to gain further insights into the mass-loss process that is presently poorly understood. We used the Parkes radio telescope to observe dust-enshrouded AGB stars and supergiants in the LMC and SMC, deriving the speed of the superwind from t

Abstract:
Stars of low and intermediate mass (0.9 ≲ M/M ⊙ ≲ 8) develop an electron-degenerate CO core after the core He-burning phase, and experience the thermally pulsing asymptotic giant branch phase (TP-AGB) as they approach the end of their evolution. Although very short lived, TP-AGB stars are of paramount importance in the study of stellar populations and galaxy evolution. In fact, being intrinsically very bright, they provide a significant contribution to the total luminosity of single stellar populations, and galaxies in general. Most of their radiation is emitted at infrared wavelengths, a spe

Abstract:
Background: Polymyalgia rheumatica (PMR) and giant cell arteritis (GCA) are two inflammatory conditions affecting people aged over 50 years. PMR is characterized by pain and stiffness in the shoulder and hip girdles. GCA, a large vessel vasculitis, is the most common form of primary systemic vasculitis. About 40-60% of patients with GCA present with concomitant PMR, and histologic features consistent with GCA can be detected on temporal artery biopsy of about 16% to 21% of patients with PMR. It is still debated whether PMR and GCA are different conditions or represent different clinical manife

Abstract:
We present new, contemporaneous Hubble Space Telescope STIS and XMM-Newton observations of the O7 III(n)((f)) star ξ Per. We supplement the new data with archival IUE spectra, to analyze the variability of the wind lines and X-ray flux of ξ Per. The variable wind of this star is known to have a 2.086-day periodicity. We use a simple, heuristic spot model that fits the low-velocity (near-surface) IUE wind line variability very well, to demonstrate that the low-velocity absorption in the new STIS spectra of N iv λ1718 and Si iv λ1402 vary with the same 2.086-day period.

Abstract:
The study of ocean sunfishes has for decades been practically synonymous with the study of Mola mola, recently listed as ‘vulnerable’ on a global scale by the International Union for Conservation of Nature. The concerns are high levels of fisheries bycatch worldwide, however sunfish bycatch is rarely identified to species level anywhere, perhaps as a long legacy of taxonomic confusion in the sunfish taxonomy has rendered identification to species level challenging. This includes the Australian and New Zealand longline fisheries, where sunfishes are listed at “High Risk” due to data deficiency.

Molecular clouds contain lower dimensional substructures, such as filaments and sheets. The collapse properties of finite filaments and sheets differ from those of spherical objects as well as infinite sheets and filaments.
