Onondaga chert : geological and palynological studies as applied to archaeology /

Cherts from the Middle Devonian Onondaga Formation of the Niagara Peninsula in Southern Ontario and Western New York State can now be distinguished from those of the Early Devonian Bois Blanc Formation of the same area based on differences in petrology, acritarchs, spores, and "Preservation Ratio" values. The finely crystalline, carbonate sediments of the Bois Blanc Formation were deposited under shallow, low energy conditions characterised by the acritarchs Leiofusa bacillum and L. minuta and a high relative abundance of the spore, Apiculiretusispora minor. The medio crystalline and bioclastic carbonate sediments of the Onondaga Formation were deposited under shallow, high energy conditions except for the finely crystalline lagoonal sediments of the Clarence Member which is characterised by the acritarchs Leiofusa navicula, L. sp. B, and L. tomaculata . The author has subdivided and correlated the Clarence Member of the Onondaga Formation using the "Preservation Ratio" values derived from the palynomorphs contained in the cherts. Clarence Member cherts were used by the Archaic people of the Niagara Peninsula for chipped-stone tools. The source area for the chert is considered to be the cobble beach deposits along the north shore of Lake Erie from Port Maitland to Nanticoke

Scholfield-Galbraith family fonds, 1865-1924

The Scholfield and Galbraith families of Dunnville, Ont. were related by marriage. Thomas Jefferson Galbraith (1842-1921) worked as a collector of canal tolls at Port Maitland, a landing waiter and searcher and an acting preventive officer in Customs. He was married to Jane Ann [Jennie] Montieth and they had five children, Margaret, Minnie Montieth, Genevieve Marion, Edith Stuart and Thomas Percy Galbraith. Genevieve Marion Galbraith was married to Harry E. Scholfield, son of Frederick Scholfield (d.1908) and Georginna Galer (d. 1888), a dry goods merchant in Dunnville. Some extent records belong to a William Scholfield who operated a mill in Dunnville. Included are records related to land lease, mortgage and bargain and sale agreements between Scholfield and various individuals, including Richard Kirkpatrick, William Kohler, Alvin Drake, Robert Ban[u]d, Henry Beckett, Sr., Samuel Waltho, Nehemiah Niece.

IS ORDINARY ELECTRIC DRILLS` VENTING PORT A POTENTIAL SOURCE OF SURGICAL INFECTION?

Objective: To evaluate the potential risk of surgical contamination by the venting port of ordinary electric drills (ED) employed in orthopaedic surgeries. Materials and Methods: an experimental laboratory, randomized study was developed to analyze EDs in surgical practice and new cleaned and sterilized equipment, which were contaminated with Bacillus atrophaeus spores at a concentration of 84 X 10(6) UFC. The air generated by the engine of each drill was collected and cultivated on sterile agar plates. Results: Positive culture was identified in two ED in surgical practice, as well as a positive culture to Bacillus atrophaeus with 1 CFU growth (1, 19 X 10(-8)). Conclusion: In the conditions of the experiment, the air generated by the venting port of the ED`s engine does not consist of a source of contamination for the surgical site.

Regional Effects of Port Infrastructure: A Spatial CGE Application to Brazil

This article attempts to elucidate one of the mechanisms that link trade barriers, in the form of port costs, and subsequent growth and regional inequality. Prior attention has focused on inland or link costs, but port costs can be considered as a further barrier to enhancing trade liberalization and growth. In contrast to a highway link, congestion at a port may have severe impacts that are spread over space and time whereas highway link congestion may be resolved within several hours. Since a port is part of the transportation network, any congestion/disruption is likely to ripple throughout the hinterland. In this sense, it is important to model properly the role nodal components play in the context of spatial models and international trade. In this article, a spatial computable general equilibrium (CGE) model that is integrated to a transport network system is presented to simulate the impacts of increases in port efficiency in Brazil. The role of ports of entry and ports of exit are explicitly considered to grasp the holistic picture in an integrated interregional system. Measures of efficiency for different port locations are incorporated in the calibration of the model and used as the benchmark in our simulations. Three scenarios are evaluated: (1) an overall increase in port efficiency in Brazil to achieve international standards; (2) efficiency gains associated with decentralization in port management in Brazil; and (3) regionally differentiated increases in port efficiency to reach the boundary of the national efficiency frontier.
