This thesis reappraises the significance of Alexander Martin Sullivan, the Irish constitutional nationalist and owner-editor of the Nation, by examining his role in carrying Young Ireland’s moderate nationalist program through the lull in popular politics between the 1840s and 1870s. Sullivan has been routinely marginalized as an important historical figure in post-Famine popular politics, yet his campaign of propping up nationalist heroes and attempts at forming nationalist organizations, primarily through the Nation, ultimately helped to revitalize nationalist politics. Although his efforts were often threatened, and even thwarted at times, by James Stephens and other advanced nationalists, Sullivan managed to preserve constitutional nationalism until the emergence of Isaac Butt as leader of the home rule movement in the 1870s. / Includes bibliography. / Thesis (M.A.)--Florida Atlantic University, 2018. / FAU Electronic Theses and Dissertations Collection

The problem under consideration is that of determining a simple and effective invariant of knots. To this end, the Conway polynomial is defined as a generalization of Alexander's original knot polynomial. It is noted, however, that the Conway polynomial is not a complete invariant. If two knots are equivalent, as defined in this investigation, then they receive identical polynomials. Yet, if two knots have identical polynomials, no information about their equivalence may be obtained. To define the Conway polynomial, the Axioms for Computation are given and many examples of their use are included. A major result of this investigation is the proof of topological invariance of these polynomials and the proof that the axioms are sufficient for the calculation of the knot polynomial for any given knot or link.

Pseudomonas aeruginosa is extremely harmful to immunocompromised individuals. An atomic force microscope was used to measure the surface forces of this bacteria’s exopolymers. These forces were characterized with the AdG force model, which is a function of brush length, probe radius, temperature, separation distance and an indefinite density variable, s. This last parameter could represent the root spacing or mesh spacing of the exopolymers. This study aims to clarify s by obtaining force values as a function of temperature. The data suggest that s represents the mesh spacing. If s is the root spacing it should remain constant regardless of the changing polymer lengths, on the other hand if it is the mesh spacing it will vary with changing temperature, as shown by the data presented in this research. This knowledge will aid in understanding and characterizing how bacteria cause infections.

"Steric forces related to the lipopolysaccharide (LPS) brush on bacterial surfaces is of great importance in biofilm research. However, the atomic force microscopy (AFM) data, or force curves, produced require extensive analysis to obtain any useful information about the sample. Normally, after several force curves have been measured, the individual curves would be fit to a model for analysis. This process is not only time-consuming, but it is also extremely subjective as it lends itself to user bias throughout the analysis. A Matlab program to analyze force curves from an AFM efficiently, accurately, and with minimal user bias has been developed and is presented here. The analysis is based on a modified version of the Alexander and de Gennes (AdG) polymer model, which is a function of equilibrium polymer brush length, probe radius, temperature, separation distance, and a density variable. The program runs efficiently by cropping curves to the region specified by the model and then fitting the data. Automating the procedure reduces the amount of time required to process 100 force curves from several days to less than two minutes. Accuracy is ensured by making the program highly adjustable. The user can specify experimental constants such as the temperature and cantilever tip geometry, as well as adjust many cropping and fitting parameters to better analyze the data. Additionally, as part of this program, researchers can compare data from related experiments by choosing to plot the calculated fit parameters using either error bars or box plots to quickly identify relationships or trends. The use of this program to crop and fit force curves to the AdG model will allow researchers to ensure proper processing of large amounts of experimental data and reduce the time required for analysis and comparison of data, thereby enabling higher quality results in a shorter period of time.

The Alexander terrane is an allochthonous terrane within the North American Cordillera. New structural mapping and geochronology within the southern Alexander terrane in the vicinity of Porcher Island provides evidence for two major tectonic events. The oldest is Late Silurian to Early Devonian magmatism and deformation assigned to the Klakas orogeny. The area has subsequently been affected by mid-Cretaceous conjugate shear zones potentially associated with tectonic escape. Northwest-striking sinistral shear zones characterize mid-Cretaceous deformation in the western Coast Belt south of Prince Rupert in north coastal British Columbia. Structurally focused mapping and geochronology has revealed a component of lateral extension to this deformation. General flow characteristics of the shear zones are identified by comparison of fabric patterns to published models for fabric development in shear zones. U-Pb ages from synkinematic dykes constrain motion on northwest-striking sinistral transpressional shear zones, including the Useless, Barrett and Salt Lagoon shear zones, to ca. 104 – 96 Ma, and dextral transpression on the north-striking Telegraph Passage shear zone to ca. 97.6 ± 0.2 Ma. The geometry, kinematics, and coeval nature of these shear zones suggests that they formed in part as a ductile conjugate set. The presence of similarly-oriented conjugate shear bands in the apex zone between sinistral and dextral shear zones further reinforces this interpretation. The orientation of these conjugate sets indicates a component of north-northwest east-southeast extension. The conjugate shear zones merge together into the Grenville Channel shear zone, a sinistral transpressional shear zone with high strike-parallel stretch. A U-Pb age of 103 ± 32 Ma from a synkinematic dyke in the Grenville Channel shear zone coincides with a previously published Lu-Hf age of 102.6 ± 3.7 Ma on synkinematic garnet. Overall, structural and geochronological data from Porcher Island and surrounding area in north coastal British Columbia indicate that mid-Cretaceous deformation was characterized by ENE-WSW (orogen normal) shortening and NNW-SSE (orogen parallel) extension. This local strain regime is consistent with large-scale mid-Cretaceous tectonic escape as proposed for the northern Cordillera at that time, expressed in coeval sinistral faulting in the Coast Belt and dextral faulting in the northern Omineca belt. The Late Silurian to Early Devonian Ogden Channel complex is a mafic to intermediate metaplutonic-metamorphic complex within the southern Alexander terrane on southern Porcher Island and adjacent Pitt Island in north coastal British Columbia. Lithological characteristics of the complex suggest that it represents the mid-crustal roots of a volcanic arc. An age of 413.3 ± 2.5 Ma from a comparatively weakly deformed quartz diorite dyke indicates that the synkinematic Ogden Channel complex is at least in part Early Devonian in age, corresponding to the Klakas orogeny that affected the Alexander terrane in southeast Alaska. Crosscutting relationships indicate that individual intrusions within the Ogden Channel complex were emplaced syn- to post-kinematically with respect to southwest-vergent sinistral reverse deformation (present coordinates). The structural and lithological characteristics of the Ogden Channel complex are consistent with the interpretation that this part of the Alexander terrane was located in the upper plate of a northeast-dipping subduction zone, which culminated in the Klakas orogeny.
