HG 295.70-295.80 Thin Section

This sample contains two different domains; a coarse grained domain with well dispersed clasts, and a fine grained domain that potentially contains organics. The coarser grained domain contains comet structures, lineations and minor rotation without a central grain.

Victory Medal

Victory Medal (Inter-Allied War Medal) which was awarded to all ranks of fighting forces. This is a circular, copper medal, lacquered bronze. It measures 3 1/2 cm in diameter and has a picture of Victory on the front. Her left arm is extended and in her right hand she holds a palm branch. The reverse shows the words "The Great War for Civilisation 1914-1919" surrounded by a wreath. This is accompanied by a watered ribbon consisting of 9 coloured stripes. "Lieut. S.D. Woodruff" is engraved on the rim. This engraving was only done for the first issue in 1914-1919.

Backbone Colouring of Graphs

Consider an undirected graph G and a subgraph of G, H. A q-backbone k-colouring of (G,H) is a mapping f: V(G) {1, 2, ..., k} such that G is properly coloured and for each edge of H, the colours of its endpoints differ by at least q. The minimum number k for which there is a backbone k-colouring of (G,H) is the backbone chromatic number, BBCq(G,H). It has been proved that backbone k-colouring of (G,T) is at most 4 if G is a connected C4-free planar graph or non-bipartite C5-free planar graph or Cj-free, j∈{6,7,8} planar graph without adjacent triangles. In this thesis we improve the results mentioned above and prove that 2-backbone k-colouring of any connected planar graphs without adjacent triangles is at most 4 by using a discharging method. In the second part of this thesis we further improve these results by proving that for any graph G with χ(G) ≥ 4, BBC(G,T) = χ(G). In fact, we prove the stronger result that a backbone tree T in G exists, such that ∀ uv ∈ T, |f(u)-f(v)|=2 or |f(u)-f(v)| ≥ k-2, k = χ(G). For the case that G is a planar graph, according to Four Colour Theorem, χ(G) = 4; so, BBC(G,T) = 4.

Interlake Tissue Mills Fire Slides

The Interlake Tissue Mills storage location was at the intersection of Glendale and Merritt Street in Merritton. In the 1850s, the Beaver Cotton Mills (later Merritton Cotton Mills) was built. It was a frame building that burned down in 1881. A sandstone structure replaced the previous building. In 1906, the cotton mill closed and in 1912, the Independent Rubber Company took over the building. The mill was doubled in size. The rubber company remained there for ten years and then the building remained vacant until 1935. Interlake Tissue Mills acquired the building for storage purposes. A fire razed the larger of the plant’s buildings on Memorial Day weekend in 1961. After the fire, Domtar used the smaller building for storage for a short time. This is currently the site of the Keg Restaurant.

Map, 55 cm. x 75 cm. (printed, coloured and mounted on a board). The map is of the proposed canal through the district of Niagara and Gore to form a junction of Lake Erie and Ontario by the Grand River compiled from the actual survey by order of the commissioners of internal navigation by James G.
