Public & private improvements in eighteenth-century Ireland : the case of the Conynghams of Slane, 1703-1821
No full textTHESIS 8892.1THESIS 8892.2The origins of the concept of improvement lie in the mid-seventeenth century and can be defined as the creation of a new landscape within which new estate villages were laid out, old settlements were restructured and revived, industries and agricultural settlements were established, and the nexus of the demesne - the country seat ? was renovated or built entirely new. The Conynghams, who were owners of vast estates in Donegal, acquired the Slane estate in 1703 and took on the mantle of the ?improving landlord?, undertaking public and private schemes which embraced the
fundamentals of improvement ideals. The aim of this study is to establish a narrative which fills out the Conynghams? story over a period of one hundred and twenty years. It illustrates the direct results of the family?s patronage and of their collaboration with entrepreneurs on the estates and beyond. In the context of the built environment, the work discusses primarily the execution of industrial architecture, engineering works and urban design. In the appraisal of the family?s most outstanding and lasting schemes, the study draws parallels with analogous plans carried out elsewhere in Ireland, and architectural setpieces are defined within the realm of the architectural and urban history of eighteenth-century Ireland. The research method used in the preparation of this work focussed on three principal sources, namely primary and secondary documentary sources, and the on-site investigation of extant structures on the Conyngham estates. Archival material, not only in Ireland, but also in England, Spain and (through the internet) Australia, revealed a wealth of information about the Conynghams and their schemes. Together with historiographical publications relating to the Conynghams, which provided significant foundations for extant histories of the family and their estate affairs, additional printed material such as parliamentary acts, contemporary newspapers and travel writings, first edition 6" Ordnance Survey maps and unpublished theses were used to support the outcome of the primary manuscript research. The results of the examination of all documentary sources were supplemented with a high level of fieldwork, involving detailed on-site inspections of extant structures, primarily Slane Mill and its associated waterworks, the Boyne
Navigation and the architectural elements of Slane Village. These investigations were in turn informed by eighteenth-century technical treatises, in order to reconstruct the buildings and engineering works in their original eighteenth-century state. The body of the thesis is divided into six sections. The first two chapters chronicle the Conynghams? purchase of the Meath properties, the involvement of William Conolly in early developments at Slane, and the inheritance issues of the next generation of the family. Presented in these two chapters is an informative context for an introduction to the next set of Conyngham improvers, and a background to their participation in future estate improvements. The following three chapters relate to the main bulk of improvements carried out at Slane between 1760 and the last decades of the century. These improvements encompass the building of Slane Mill, the development of Slane Village and the completion of the Boyne Navigation. The sixth and final chapter seeks to complete the picture of the life of the Conynghams? most distinguished family member, William Burton Conyngham, renowned not only as a tireless patron of the arts and a Wide Street Commissioner in Dublin, but also, as this work will show, architect of extensive improvements on the family estates in the latter half of the eighteenth century
Li-7 Nmr and Ionic-conductivity Studies of Gel Electrolytes Based On Poly(methylmethacrylate)
No full textGel electrolytes synthesized from poly(methylmethacrylate), ethylene carbonate, propylene carbonate and various lithium salts [LiClO4, LiAsF6, or LiN(CF3SO2)(2)] have been investigated by differential scanning calorimetry, electrical conductivity, and Li-7, F-19 and As-75 NMR spectroscopy. Although the ionic conductivities of the gels approach those of liquid electrolytes above room temperature, the NMR results indicate that the immediate environments of both the cations and anions differ significantly in the gel and in the liquid. Thus the presence of microscopic regions of pure liquid electrolyte in the gel can be ruled out

Information brokers, fairness, and privacy in publicly accessible information
No full textThe European Union, Canada, and the United States have each grappled with what counts as fair business practices in relation to information services that collect and package personal information that has ended up in one way or another online. On the open internet, this personal information often originates from two types of online sources: public records like arrests, mugshots, court decisions, and bankruptcy records; and user-generated content hosted on social media platforms and sites. This article argues that personal information that has been exposed to public view — be it by a government institution, another individual or organization, or by the data subject him or herself — should not be considered fair game to any and all subsequent commercial exploitation. The blunt concept of “public” information should be refined to a more nuanced understanding of “publicly accessible” information, where public access can be limited to particular purposes. By focusing on fairness in business dealings in publicly accessible personal information, it should be possible to move beyond a fixation on locating the elusive divide between private and public online information, and instead frame privacy as situated in a three-way balance of interests between the business, the public, and the data subject
Cooling rates of neutron stars and the young neutron star in the Cassiopeia A supernova remnant
No full textWe explore the thermal state of the neutron star in the Cassiopeia A supernova remnant using the recent result of Ho & Heinke that the thermal radiation of this star is well described by a carbon atmosphere model and the emission comes from the entire stellar surface. Starting from neutron star cooling theory, we formulate a robust method to extract neutrino cooling rates of thermally relaxed stars at the neutrino cooling stage from observations of thermal surface radiation. We show how to compare these rates with the rates of standard candles – stars with non-superfluid nucleon cores cooling slowly via the modified Urca process. We find that the internal temperature of standard candles is a well-defined function of the stellar compactness parameter x=rg/R, irrespective of the equation of state of neutron star matter (R and rg are circumferential and gravitational radii, respectively). We demonstrate that the data on the Cassiopeia A neutron star can be explained in terms of three parameters: f?, the neutrino cooling efficiency with respect to the standard candle; the compactness x; and the amount of light elements in the heat-blanketing envelope. For an ordinary (iron) heat-blanketing envelope or a low-mass (? 10?13 M?) carbon envelope, we find the efficiency f?? 1 (standard cooling) for x? 0.5 and f?? 0.02 (slower cooling) for a maximum compactness x? 0.7. A heat blanket containing the maximum mass (?10?8 M?) of light elements increases f? by a factor of 50. We also examine the (unlikely) possibility that the star is still thermally non-relaxe
From Scanning to Sexting: The Scope of Protection of Dignity-Based Privacy in Canadian Child Pornography Law
No full textThe Canadian approach to privacy rights in one\u27s body is embedded in the relationship between interests in privacy, bodily integrity, and human dignity. Clarifying these interests is complicated by Canada\u27s middle-ground stance between the European dignity-based approach to privacy and the US liberty-based orientation. The Canadian approach is closer to the European model when intrusions upon the body are conceived as wholly or mostly non-consensual (e.g., strip searches, voyeurism, and most child pornography). However, once consent plays a potentially determinative rote, the US liberty-based approach gains ground. This reluctance to fully align dignity with privacy results in confusion about the scope of ongoing privacy interests in nude images, as evidenced by recent debates about the use of airport body scanners and the appropriate response to adolescent sexting. The author argues that a clearer alignment with a dignity-based approach emerging in Canadian child pornography jurisprudence would better address the harms caused by misuse of photography, as applicable to both children and adults
Revisiting the relativistic ejection event in XTE J1550-564 during the 1998 outburst
No full textWe revisit the discovery outburst of the X-ray transient XTE J1550−564 during which relativistic jets were observed in 1998 September, and review the radio images obtained with the Australian Long Baseline Array, and light curves obtained with the Molonglo Observatory Synthesis Telescope and the Australia Telescope Compact Array. Based on Hi spectra, we constrain the source distance to between 3.3 and 4.9 kpc. The radio images, taken some 2 d apart, show the evolution of an ejection event. The apparent separation velocity of the two outermost ejecta is at least 1.3c and may be as large as 1.9c; when relativistic effects are taken into account, the inferred true velocity is ≥ 0.8c. The flux densities appear to peak simultaneously during the outburst, with a rather flat (although still optically thin) spectral index of −0.2

X-Ray Emission From PSR 0355+54
No full textWe have obtained a 20 ks observation of PSR 0355+54 using the ROSAT PSPC. The pulsar is detected with a count rate of 4:2(\Sigma1:3) \Theta 10 \Gamma3 s \Gamma1 above the background. While the ¸ 70 source counts are insufficient for spectral fitting, we have derived source parameters for specific cases of power law as well as blackbody spectra. For a Crab-like spectrum (photon index ff = 2) we find L x (0:1 \Gamma 2:4 keV) = 1:0 \Theta 10 32 erg s \Gamma1 , somewhat higher than upper limits reported from Einstein observations but consistent with typical L x vs E values for other pulsars. For blackbody emission, we derive a temperature upper limit of ¸ 9:5 \Theta 10 5 K for emission from the entire neutron star surface, which is consistent with standard models for cooling of the neutron star interior given a characteristic age 10 5:75 yr. No evidence is present for modulation at the 156 ms pulsar period, setting a weak upper limit of ¸ 75% for the pulsed fraction of the X-..
