Harrison Hall Opening (January 1999)

The people involved in opening Harrison Hall.

Welch Hall

View of Welch Hall from the southwest before the Walker Complex and South Block existed.

Welch Hall Overhead

This view from the Twer facing southwest shows the College of Education, now Welch Hall, and the former parking lot situated west of it (behind it).

Welch Hall Northern View

View of Welch Hall from just north of it where Scotiabank Hall is now.

Welch Hall South Entrance

The main entrance to Welch Hall and the David S. Howes Theatre, formerly the Playhouse. The Schmon Tower can be seen in the background. Note the sign reading 'St. Catharines Teachers College. This photograph thus precedes the amalgamation of the College with Brock University.

Harrison Hall (January 1999)

Harrison Hall holds the new Student Health Centre and Athletic Therapy Clinic. The centre provides the University's Health Services Department with a greater amount of space for students and staff, and the building is designed to make treatment more comfortable and efficient. The centre includes four examination rooms as part of the increased space. It is named after Bernard Harrison, a former Brock physics demonstrator who has donated over $1 million to the University.

Inniskillin Hall (June 1999)

The building, which is attached to the Mackenzie Chown complex, holds facilities for Brock's Cool Climate Oenology and Viticulture Institute. The Institute, which studies grape growing and wine production, is the only one of its kind in Canada, and only the third of its kind in North America. It includes specialized research laboratories, a climate-controlled wine cellar, a wine library, and a museum. The building is named after a Niagara winery, Inniskillin Wines.

Extracting Ramachandran torsional angle distributions from 2D NMR data using Tikhonov regularization /

Solid state nuclear magnetic resonance (NMR) spectroscopy is a powerful technique for studying structural and dynamical properties of disordered and partially ordered materials, such as glasses, polymers, liquid crystals, and biological materials. In particular, twodimensional( 2D) NMR methods such as ^^C-^^C correlation spectroscopy under the magicangle- spinning (MAS) conditions have been used to measure structural constraints on the secondary structure of proteins and polypeptides. Amyloid fibrils implicated in a broad class of diseases such as Alzheimer's are known to contain a particular repeating structural motif, called a /5-sheet. However, the details of such structures are poorly understood, primarily because the structural constraints extracted from the 2D NMR data in the form of the so-called Ramachandran (backbone torsion) angle distributions, g{^,'4)), are strongly model-dependent. Inverse theory methods are used to extract Ramachandran angle distributions from a set of 2D MAS and constant-time double-quantum-filtered dipolar recoupling (CTDQFD) data. This is a vastly underdetermined problem, and the stability of the inverse mapping is problematic. Tikhonov regularization is a well-known method of improving the stability of the inverse; in this work it is extended to use a new regularization functional based on the Laplacian rather than on the norm of the function itself. In this way, one makes use of the inherently two-dimensional nature of the underlying Ramachandran maps. In addition, a modification of the existing numerical procedure is performed, as appropriate for an underdetermined inverse problem. Stability of the algorithm with respect to the signal-to-noise (S/N) ratio is examined using a simulated data set. The results show excellent convergence to the true angle distribution function g{(j),ii) for the S/N ratio above 100.

Welland Canal Survey of Lands Estate of Hall Davis and Jeremiah Adley 1834

Survey map and description of the Estate of Hall Davis and Jeremiah Adley's land created by The Welland Canal Company. Included is a written description of the land along with a drawing of the land. Noteable features include; Holland road, Adley's house, waste weir. The total land for the Estate of Hall Davis is 27 acres and 2 perches. The total land for Adley is 3 acres. The deed for the Estate of Hall Davis is dated August 16th 1834 and contains Samuel Swayze's name. Swayze's name is also written under Hall Davis' name. The deed for Adley's land is dated December 1st 1827. Surveyor notes are seen in pencil on the map.
