Abstract:
DNA polymerases play a fundamental role in the transmission and maintenance of genetic information and have become an important in vitro diagnostic and analytical tool. The Loop-mediated isothermal DNA amplification (LAMP) method has major applications for disease and pathogen detection and utilises the unique strand-displacement activity of a small group of thermostable DNA polymerases. The Large (Klenow-like) Fragment of Geobacillus stearothermophilus DNA polymerase I (B.st LF Pol I) currently serves as the enzyme of choice for the majority of these isothermal reactions, with few alternative

Abstract:
The suitability of electromagnetic actuating devices for application to machines with ever more demanding response time specifications is discussed, with the proposal that piezoelectric actuator technology can produce practical devices with faster response times than solenoids, for example. This thesis discusses and validates the proposition that the performance of piezoelectric ceramic actuators makes them viable devices for inclusion in high-speed machine applications, where rapid clutching using two-state actuation is required. Further, techniques are devised and explored for the design and

Abstract:
The availability of DNA samples that are of adequate quality and quantity is essential for any genetic analysis. The fields of forensic biology and clinical diagnostic pathology testing often suffer from limited samples that yield insufficient DNA material to allow extensive analysis. This study examined the utility of a recently introduced whole genome amplification method termed Multiple Displacement Amplification (MDA) for amplifying a variety of limited sample types that are commonly encountered in the fields of forensic biology and clinical diagnostics.

Abstract:
One of the great challenges of microbial analysis in natural environments derives from the fact that a large proportion of microorganisms present is not culturable in standard conditions. To overcome this, various molecular approaches are widely used.

The aim of this project was to study freshwater samples obtained from various environments in Ireland in order to identify dominant bacterial species and key genes asso

Targeting DNA has the advantage over proteins for cancer remediation because of the fewer copies of the ligands required for the desired therapeutic effect.

The primary drawback of this treatment is the non-specific binding that affects both cancerous and non-cancerous cells.
