Fast atom bombardment mass spectrometry of the coordination complexes of the ligand 5, 5, 7, 12, 12, 14- hexamenthyl-1, 4, 8, 11-tetraazacycloteradecane

A number of metal complexes containing the ligand 5,5,7,12,12,14-hexamethyl-l,4,8,11-tetra-azatetradecane were synthesized and analyzed using electron impact (EI) and fast atom bombardment (FAB). The FAB mass spectra were obtained in positive and negative ion mode. FAB in the positive ion mode proved to be the most successful technique for the identification of these compounds. In the majority of cases the spectra obtained using positive ion FAB were structurally informative, although not all showed molecular (M+) or quasimolecular ([M+H]+) ions. The fragmentations observed were characteristic of the ligands, and were interpreted based on the chemistry of these compounds.

An investigation on peer feedback for EFL students ages 10 to 14 /

The purpose of this study was to leam more about how EFL (English as Foreign Language) students interacted during peer feedback conferences. Thirty EFL students from Mexico aged 10 to 14 years old participated in this study. The following four main questions were addressed: 1 . What criteria did the students use to evaluate their peers' writing? 2. What revisions were made in relation to peer feedback comments? 3. What was the students' behaviour like during peer feedback conferences? 4. What were the students' perceived attitudes concerning peer feedback conferences? Each of the 30 students wrote a first and a second draft and then took part in a peer feedback conference. All students were interviewed and asked to rate a story and provide a peer feedback comment for the author during interview. The study found that the EFL students were able to provide comments to their peers' writing, but only after their third conference were they actually able to provide higher level comments. The majority of students said that they liked peer feedback sessions. The results also indicated that the students needed more practice with their revisions because they did not make a lot of revisions to make their writing clearer with fewer mistakes. This study concludes that there still needs to be further research. First of all, it would be useful to conduct a similar study with EFL students but one that is conducted over a longer period of time in order to determine if the students continued to develop their peer feedback comments and revision strategies.

Second Welland Canal - Book 1, Survey Map 14 - St. Catharines and Lock 5

Survey map of the Second Welland Canal created by the Welland Canal Company showing the Canal along the eastern edge of the Town of St. Catharines. Identified structures associated with the Canal include Lock 5 and the towing path. The surveyors' measurements and notes can be seen in red and black ink and pencil. Local area landmarks are also identified and include bridges, streets, and roads (ex. Queenston Street, St. Catharines Macdamized Road and Suspension Bridge), a Pond, a number of unnamed bridges, Stinson's Distillery, and R. Collier's Saw Mill. Properties and property owners of note are: Concession 6 Lots 14 and 15, R. Collier, W. Gillespie, Orson Phelps, W. Chase, M. Bryant, John Soper, Winsor Chace, John Berryman, John Boyle, J. Madigan, B. F. Reynolds, W. Smaill, F. Stinson, G. Ward and Mrs. Soper.

Second Welland Canal - Book 2, Survey Map 4 - Locks 11, 12, 13, 14 and 15 in Grantham

Survey map of the Second Welland Canal created by the Welland Canal Company showing the Grantham Township along the outskirts of Merritton. Identified structures associated with the Canal include Locks 11, 12, 13, 14, and 15, Lock House Lot, and the towing path. The surveyors' measurements and notes can be seen in red and black ink and pencil. Several stones likely used in the measurements are identified on the map. Local area landmarks are also identified and include streets and roads(ex. Hartzel Road and Macadamized Road), the Great Western Railroad, Swing Bridge, Thorold Station and its structures (ex. freight house, office, water tank, and wood house), Gordon and Mackay Houses, Gordon and Mackay's Cotton Mill, hydraulic race, a wharf, pond, and an unnamed bridge. Properties and property owners of note are: Concession 9 Lots 12 and 13, A. Bradley, John O'Coner, G. Grant, J. Bradley, J. Vanderburgh, O. Clifford and a parcel of land leased Gordon and Mackay.
