Woodruff Family fonds, 1784 – 1983, (non-inclusive)

The Woodruff Family Collection: From the time the Woodruff Family came to Canada from the United States in 1795, they took an active role in the forming of their communities both in a civic and social manner. This is evident through the documents contained in this collection. The Woodruffs played an active role in the battles fought in Upper Canada and they were an integral part of the Village of St. Davids. They were educated, business-minded and socially engaged. They accumulated much of their fortune through land dealings. Much of this collection focuses on Samuel DeVeaux Woodruff who was principally a businessman. His dedication to his work is shown through his numerous undertakings. He made his mark on the Niagara Peninsula through his work on the railways, roads, marsh land revisions, canals and the paper industry. He was also involved with the founding of the Long Point Company and he took control of building DeVeaux Hall down to the last detail. His offspring inherited his work ethic and his business acumen. The people who married into the Woodruff Family also possessed key social, political and business ties. Anne and Margaret Clement were from a staunch Loyalist background. Samuel Zimmerman was instrumental to the founding of Niagara Falls and Judge Samuel DeVeaux left behind a legacy for poor and homeless boys in Niagara Falls, New York. The Woodruff Family undoubtedly left a mark on the Niagara Peninsula. This collection brings to light many endeavours of the family and their varied contributions.

Report sent to the President and Director of the Port Dalhousie and Thorold Railway stating that the location of the line extension of the railway is completed

Report sent to the President and Director of the Port Dalhousie and Thorold Railway stating that the location of the line extension of the railway is completed. The distance from Thorold Station to Port Colborne is 20 miles. The estimate provides for construction of a permanent structure across the Chippewa and Welland River. Estimates for building a first class road, culverts and bridges will be of permanent and durable masonry. This includes estimates for various station buildings such as a warehouse in Port Colborne and a warehouse in Port Dalhousie. Surveys and plans are ready and will be registered this week. This is signed by S.D. Woodruff (2 copies) [one appears to be a rough copy] (The rough copy is 5 pages, handwritten and the other copy is 6 pages, handwritten), Apr. 8, 1857.

Superconformal transformations of theN=4 supersymmetric Yang-Mills theory

We obtain the superconformal transformation laws of theN=4 supersymmetric Yang-Mills theory and explicitly demonstrate the closure of the algebra.

Path-integral derivation of the superconformal anomaly for the N=1 supersymmetric Yang-Mills theory

Fujikawa's method of evaluating the supercurrent and the superconformal current anomalies, using the heat-kernel regularization scheme, is extended to theories with gauge invariance, in particular, to the off-shell N=1 supersymmetric Yang-Mills (SSYM) theory. The Jacobians of supersymmetry and superconformal transformations are finite. Although the gauge-fixing term is not supersymmetric and the regularization scheme is not manifestly supersymmetric, we find that the regularized Jacobians are gauge invariant and finite and they can be expressed in such a way that there is no one-loop supercurrent anomaly for the N=1 SSYM theory. The superconformal anomaly is nonzero and the anomaly agrees with a similar result obtained using other methods.

Structure constants of beta deformed super Yang-Mills

We study the structure constants of the N = 1 beta deformed theory perturbatively and at strong coupling. We show that the planar one loop corrections to the structure constants of single trace gauge invariant operators in the scalar sector is determined by the anomalous dimension Hamiltonian. This result implies that 3 point functions of the chiral primaries of the theory do not receive corrections at one loop. We then study the structure constants at strong coupling using the Lunin-Maldacena geometry. We explicitly construct the supergravity mode dual to the chiral primary with three equal U(1) R-charges in the Lunin-Maldacena geometry. We show that the 3 point function of this supergravity mode with semi-classical states representing two other similar chiral primary states but with large U(1) charges to be independent of the beta deformation and identical to that found in the AdS(5) x S-5 geometry. This together with the one-loop result indicate that these structure constants are protected by a non-renormalization theorem. We also show that three point function of U(1) R-currents with classical massive strings is proportional to the R-charge carried by the string solution. This is in accordance with the prediction of the R-symmetry Ward identity.

Traité général des pesches : et histoire des poissons qu'elles fournissent tant pour la subsistance des hommes que pour plusieurs autres usages qui ont rapport aux arts et au commerce. [3 volumes bound in 2 parts in folio]

Early illustrated book about fish, fishing and fisheries by one of the preeminent scientific investigators of the French enlightenment. This work deals extensively with the species of fish found in Europe and beyond, their habits and habitats, techniques and equipment used in fishing and fish processing, and many other aspects of these endeavours. Roughly 185 engraved plates illustrate the text. The scans for this version come from 3 volumes bound in two parts in folio.

Yang-Mills theory in six-dimensional superspace

The superspace approach provides a manifestly supersymmetric formulation of supersymmetric theories. For N= 1 supersymmetry one can use either constrained or unconstrained superfields for such a formulation. Only the unconstrained formulation is suitable for quantum calculations. Until now, all interacting N>1 theories have been written using constrained superfields. No solutions of the nonlinear constraint equations were known.

In this work, we first review the superspace approach and its relation to conventional component methods. The difference between constrained and unconstrained formulations is explained, and the origin of the nonlinear constraints in supersymmetric gauge theories is discussed. It is then shown that these nonlinear constraint equations can be solved by transforming them into linear equations. The method is shown to work for N=1 Yang-Mills theory in four dimensions.

N=2 Yang-Mills theory is formulated in constrained form in six-dimensional superspace, which can be dimensionally reduced to four-dimensional N=2 extended superspace. We construct a superfield calculus for six-dimensional superspace, and show that known matter multiplets can be described very simply. Our method for solving constraints is then applied to the constrained N=2 Yang-Mills theory, and we obtain an explicit solution in terms of an unconstrained superfield. The solution of the constraints can easily be expanded in powers of the unconstrained superfield, and a similar expansion of the action is also given. A background-field expansion is provided for any gauge theory in which the constraints can be solved by our methods. Some implications of this for superspace gauge theories are briefly discussed.
