We demonstrate a Digital Holographic method where two different substances in a blend can be discerned. The method requires only one set of exposures and one reconstruction in the plane of focus. The large scale phase variation of the phase image is unwrapped by Flynn’s discontinuity algorithm to reveal which regions in the sample the phase has decreased or increased upon transmission of the illumi
This thesis concerns growth and characterization of gold-particle seeded nanowires of III-V semiconductor materials (III-V NWs). The nanowires were grown using metal-organic vapour phase epitaxy (MOVPE) and characterized by various microscopy techniques. In particular cross-sectional scanning tunnelling microscopy (XSTM) and cathodoluminescence microscopy (CL) were employed to investigate heterost
The western fertility decline is arguably the most significant demographic change to have occurred in the past 200 years, yet its causes and processes are still shrouded in ambiguity due to a lack of individual-level longitudinal data. A growing body of research has helped improve our understanding of the decline's causes by examining the development of socioeconomic differences in fertility using
Employing high-resolution spectra obtained with the near-UV-sensitive detector on the Keck I HIRES, supplemented by data obtained with the McDonald Observatory 2d-coudé, we have performed a comprehensive chemical composition analysis of the bright r-process-rich metal-poor red giant star HD 221170. Analysis of 57 individual neutral and ionized species yielded abundances for a total of 46 elements
Type 1 diabetes (T1D) is an autoimmune disease associated with the destruction of pancreatic β cells and genetically linked to human leukocyte antigen (HLA) class II DR3-DQ2 and DR4-DQ8 haplotypes. The +49A/G polymorphism of the immunoregulatory cytotoxic T-lymphocyte antigen 4 (CTLA-4) gene is also associated with T1D. Genetic and environmental risk factors precede the onset of T1D, which is char
Abstract in UndeterminedThe digital age has brought with it advantages and disadvantages. Few would deny the benefit of being able to store entire song collections on pocket-sized MP3 players. Fewer still would disregard the merits of grandparents in Sydney being able to have face-to-face conversations with grandchildren in Berlin.Certain problems however, have also developed. The music and film i
