Electron tomography of defects
Tomography of crystal defects in the electron microscope was rst attempted in 2005 by the author and colleagues. This thesis further develops the technique, using a variety of samples and methods. Use of a more optimised, commercial tomographic reconstruction program on the original GaN weakbeam …

Investigating the architectural drivers of defects in open-source software systems : an empirical study of defects and reopened defects in GNOME
… competent software engineers, the existence of defects in production is unlikely to be an acceptable situation. And yet, we find that in several such systems, defects remain a reality. Furthermore, the number of changes that are fixed only to then be reopened is noticeable. The implications of …

IRON OVERLOAD AND BIRTH DEFECTS
Large, intravenous doses of iron-dextran are teratogenic in a number of laboratory species (M Phil). To elucidate the mechanism, studies were performed in rats and rabbits to identify possible maternal, placental and foetal sites of action. Maternal toxicity, manifested by bodyweight depression, …

Meiotic defects in infertile men
… of aneuploid sperm. Thus, we hypothesized that defects in early meiotic events may contribute to both male infertility and the production of aneuploid sperm. We used immunofluorescent techniques to observe the synapsis and recombination of chromosomes during meiosis, and fluorescent in-situ …

Treatment of Periodontal Furcation Defects
… bone regeneration in class II furcation defects, together with the rationale for the development of this procedure. Results of treatment of 30 defects with this technique are presented in a subsequent report (Gantes et al. 1987).</p>

Network defects in vulcanised rubber
The molecular weight of natural rubber is very high and must be reduced by mastication so that it has sufficient plasticity to enable the incorporation of compounding ingredients. Such a reduction in molecular weight increases the number of elastically ineffective chain ends which reduces the …

Anyonic symmetry and twist defects
… Abelian theories, and as a result allow for defects which host non-Abelian zero modes. We first formulate the symmetries of the anyonic excitations of Abelian topological states. Then, we study properties of semiclassical point defects, called twist defects, which permute orbiting anyons by …

Defects and Rearrangements in Disordered Solids
… <p>We develop a new method to isolate localized defects from extended vibrational modes in disordered solids. This method augments particle interactions with an artificial potential that acts as a high-pass filter: it preserves small-scale structures while pushing extended vibrational modes to …

Modelling visual search for surface defects
… to investigate how well human observers can nd defects in textured surfaces, over a wide range of task di culties. Stimuli for experiments will be generated using texture synthesis methods and human search strategies will be captured by use of an eye tracker. Two di erent modelling approaches …

DEFECTS AND LIFETIME PREDICTION OF GERMANIUM MOSFETS
… The different stress-time dependence of defects below Ev and around Ec indicates that they originate from different defects. Quantization effect, Fermi level pinning, and discharge voltage step were considered. The defect differences in terms of the energy level were investigated by using …
