Birds are one of the best studied animal groups in the world but are also amongst the most endangered. The wealth of ecological information has shown habitat protection to be vital to bird biodiversity, but habitat loss and degradation continue…

The constant growth in complexity of engineered physical (electrical, mechanical etc.) systems has led to the development of software tools to store and reuse design knowledge to simplify the creation of such systems. Models that encode structure and behaviour of…

The importance of technology in education cannot be underestimated. There are compelling reasons for developing nations like Pakistan to introduce technology in their educational systems. Nevertheless the approach and methods used in introducing technology in schools are premised on an…

The promotion of Shakespeare to the centre of the English literary canon was largely facilitated by ten major eighteenth-century editions of his plays: by Nicholas Rowe (1709), Alexander Pope (1723-25), Lewis Theobald (1733), Thomas Hanmer (1744), William Warburton (1747), Samuel…

Background: Dance is a modality of choice in rehabilitation, because it combines the benefits of aerobic exercise with an enjoyable social activity. Despite the scientific evidence supporting the use of dance in rehabilitation, this treatment modality is rarely used in…

Electoral authoritarian regimes represent the modal type of political regimes in the developing world. To control electoral outcomes, such regimes may deploy a broad variety of repressive and manipulative measures. Despite their empirical as well as normative relevance, we possess…

"We shortly recall the mathematical and physical aspects of Talbot’s self-imaging effect occurring in near-field diffraction. In the rational paraxial approximation, the Talbot images are formed at distances z = p/q, where p and q are coprimes, and are superpositions…

The objective of this thesis is to present the fabrication of a multiphoton microscope and the underlying theory responsible for its proper functioning. A basic introduction to nonlinear optics will give the necessary knowledge to the reader to understand the…

Mutations in the parkin gene are responsible for an early-onset autosomal-recessive form of Parkinson's disease. Parkin is an E3 ubiquitin ligase that acts in the covalent attachment of the small protein ubiquitin to substrate proteins. Although many parkin substrates have…
