Mary Tyrell Bell [n.d.]

A cabinet card portrait of a young Mary Tyrell (later Bell). The photograph is undated, however, it is believed to be from the 1880s or 1890s. Mary Tyrell married Charles Bell in 1894 in St. Catharines, Ontario. They initially settled in Erie, Pennsylvania but relocated to St. Catharines less than three years later. This photograph was in the possession of Mary Tyrell Bell's grandson, Rick Bell. The Bell family is descended from Black slaves from the United States.

Vera Sloman, Richard Bell, Iris Sloman Bell and Bert Sloman [n.d.]

This black and white family photo is undated yet believed to be in 1939 on the wedding day of Richard and Iris Bell. Pictured in this photo are, from right, Vera, Richard Bell, Iris Sloman Bell, and Bert Sloman. This photo was in the possession of Rick Bell, of St. Catharines, son of Richard and Iris. The Bell - Sloman families have descendants who are former African American slaves.Bert Sloman (Albert Edward Sloman) passed away in 1986 at Kitchener - Waterloo, Ontario. His wife, Vera Matilda Sloman, passed away January 4, 2011 at Cambridge Memorial Hospital. They had a son, Ron Sloman.

Determining rotational direction of rotation structures using prolate shaped grains within till

Micromorphology is used to analyze a wide range of sediments. Many microstructures have, as yet, not been analyzed. Rotation structures are the least understood of microstructures: their origin and development forms the basis of this thesis. Direction of rotational movement helps understand formative deformational and depositional processes. Twenty-eight rotation structures were analyzed through two methods of data extraction: (a) angle of grain rotation measured from Nikon NIS software, and (b) visual analyses of grain orientation, neighbouring grainstacks, lineations, and obstructions. Data indicates antithetic rotation is promoted by lubrication, accounting for 79% of counter-clockwise rotation structures while 21 % had clockwise rotation. Rotation structures are formed due to velocity gradients in sediment. Subglacial sediments are sheared due to overlying ice mass stresses. The grains in the sediment are differentially deformed. Research suggests rotation structures are formed under ductile conditions under low shear, low water content, and grain numbers inducing grain-to-grain interaction.

Letter to Mr. Thomas Bell

Letter to Mr. Thomas Bell asking him to use all due diligence to bring this claim before the committee. [This letter is unsigned but is from Port Robinson and likely written by Samuel D. Woodruff], Dec. 15, 1848.

Letter from Port Robinson to Mr. Bell

Letter from Port Robinson to Mr. Bell acknowledging the receipt for the affidavits which were sent. The writer says that he is not the owner of the land as Mr. Bell supposes. The writer is anxious for this matter to be brought before the committee and says that this matter has been 2 years in Mr. Steer’s hands in neglect. [The letter is unsigned, but the writer is probably Samuel D. Woodruff], April 10, 1849.

The euchromatic and heterochromatic landscapes are shaped by antagonizing effects of transcription on H2A.Z deposition

A role for variant histone H2A.Z in gene expression is now well established but little is known about the mechanisms by which it operates. Using a combination of ChIP-chip, knockdown and expression profiling experiments, we show that upon gene induction, human H2A.Z associates with gene promoters and helps in recruiting the transcriptional machinery. Surprisingly, we also found that H2A.Z is randomly incorporated in the genome at low levels and that active transcription antagonizes this incorporation in transcribed regions. After cessation of transcription, random H2A.Z quickly reappears on genes, demonstrating that this incorporation utilizes an active mechanism. Within facultative heterochromatin, we observe a hyper accumulation of the variant histone, which might be due to the lack of transcription in these regions. These results show how chromatin structure and transcription can antagonize each other, therefore shaping chromatin and controlling gene expression.
