The measured variation of the Debye-Waller factor of aluminum from 295K to 815K by using the energy dispersive x-ray diffraction technique

The Energy Dispersive X-ray Diffraction System at Brock University has been used to measure the intensities of the diffraction lines of aluminum powder sample as a function of temperature. At first, intensity measurements at high temperature were not reproducible. After some modifications have been made, we were able to measure the intensities of the diffraction lines to 815K, with good accuracy and reproducibility. Therefore the changes of the Debye-Waller factor from room temperature up to 815K for aluminum were determined with precision. Our results are in good agreement with those previously published.

This small cabinet card photograph was in the possession of the Iris Sloman Bell family of St. Catharines. Relatives of the Sloman - Bell families include former African American slaves who settled in Canada.Two photographers by the name of Arthur are listed as working in St. Catharines, Ontario in the second half of the 19th century. Charles A. Arthur was a photographer from 1880 - 1883, while Charles P. Arthur (possibly a son?) is listed as a photographer in 1898. Source: Phillips, Glen C.

Lizzie Sloman is pictured with her son, not identified by name, in this undated black and white photograph. The location of the photograph is also unknown. This item was in the possession of Rick Bell, of St. Catharines, whose mother Iris Sloman Bell, was sister to Lizzie.

I Believe in me, not OCB: Evaluation of Group Function-Based CBT as a Treatment for Obsessive Compulsive Behaviour in Four Children with HFA

Researchers have conceptualized repetitive behaviours in individuals with Autism Spectrum Disorder (ASD) on a continuum oflower-Ievel, motoric, repetitive behaviours and higher-order, repetitive behaviours that include symptoms ofOCD (Hollander, Wang, Braun, & Marsh, 2009). Although obsessional, ritualistic, and stereotyped behaviours are a core feature of ASD, individuals with ASD frequently experience obsessions and compulsions that meet DSM-IV-TR (American Psychiatric Association, 2000) criteria for Obsessive-Compulsive Disorder (OCD). Given the acknowledged difficulty in differentiating between OCD and Autism-related obsessive-compulsive phenomena, the present study uses the term Obsessive Compulsive Behaviour (OCB) to represent both phenomena. This study used a multiple baseline design across behaviours and ABC designs (Cooper, Heron, & Heward, 2007) to investigate if a 9-week Group Function-Based Cognitive Behavioural Therapy (CBT) decreased OCB in four children (ages 7 - 11 years) with High Functioning Autism (HFA). Key treatment components included traditional CBT components (awareness training, cognitive-behavioural skills training, exposure and response prevention) as well as function-based assessment and intervention. Time series data indicated significant decreases in OCBs. Standardized assessments showed decreases in symptom severity, and increases in quality of life for the participants and their families. Issues regarding symptom presentation, assessment, and treatment of a dually diagnosed child are discussed.

The Death of Brock at Queenston Heights, 1812: Imperial Tobacco Company silk card

General Isaac Brock was a British Army officer and administrator who was promoted to Major General. He was responsible for defending Upper Canada against the United States. He died at the Battle of Queenston Heights during the War of 1812. Bartholome Houde and George E. Tuckett (Tuckett was mayor of Hamilton Ontario in 1896) manufactured and sold tobacco before Confederation. In 1841, the company was called B. Houde and Grothe. When Houde retired in 1822 his son in law, Francis Xavier Dussault took over the company. In 1903, the company was called B. Houde and Company Ltee. and it was run by Dussault’s two sons J.A. Dussault and J.E. Dussault. The B. Houde Company had become part of American Tobacco Ltd. which merged with Empire Tobacco Co. Ltd. to form the Imperial Tobacco Company in 1908 in the St. Henri district of Montreal. In 2008, the company celebrated their centennial. Cigarette silks were either enclosed in packets of cigarettes or were redeemable by mail. People would sew these silks together to create quilts or table covers. Some cigarette packages even included instructions for making these items.
