Columbus Feeder Canal
No full textOne black and white photographic print of the Columbus Feeder Canal in Columbus in Franklin County, Ohio looking north from south of Main Street. A canal boat can be seen docked in the water with two mules are hooked up to pull it. The C. Harris Co. building can be seen behind the boat and several buildings and wooden structures can be seen in the background. The Columbus Feeder Canal was an eleven-mile waterway that connected the Scioto River at Columbus with the Ohio and Erie Canal at Lockbourne
Groundbreaking Site of Canal 2
No full textOne black and white photographic print of a historical marker dedicated at the site of the groundbreaking for the Ohio and Canal in Licking County, Ohio. The marker consists of a plaque attached to a stone on a pediment that reads: ""On this spot, Saturday July 4 1825, The Ohio Canal was Started. Saturday July 4 1925 This Marker was Erected By Licking County Citizens."" Cultivated fields can be seen in the background while trees stand in the distance

Miami and Erie Canal through Dayton plat map
No full textCanal plat map showing a section of the Miami and Erie Canal through Dayton in Montgomery County, between stations 18 and 43. Roads, properties, railways and other landmarks along the route are noted, along with a chart titled "Distances in feet from top water line of Canal to inner rail of C. H. & D. [Cincinnati, Hamilton & Dayton] track." The map was created under the direction of the members of the Canal Commission of the state of Ohio and approved by the Chief Engineer of the Department of Public Works (variously referred to as the Board of Public Works and the Division of Public Works).
Construction on the Miami and Erie Canal took place between 1825 and 1845, and the finished route connected Cincinnati and Toledo, as well as the Ohio River with Lake Erie

Water quality modeling for the Kennet and Avon Canal, a navigational canal in an inland catchment
No full textThe Kennet and Avon Canal in southern England is experiencing severe water quality problems caused by inorganic sediment and algae. These water quality problems are affecting the angling sport of fishermen downstream of the confluence of the canal with the River Kennet. The Environment Agency has been called upon to remedy these issues, but before proceeding they desire a computer model capable of predicting the water quality impacts of various scenarios under consideration. No such model was available to them.
This project identified the key solids generation and transport processes to be included in a water quality model for inland navigational canals. Where available, equations from the literature describing relevant processes were used or modified for inclusion in a canal modeling algorithm. Where literature was not available, water quality samples were taken to characterize needed relationships. The final algorithm was coded and tested using a simplified dataset that allowed clear evaluation of the simulated processes.
After successful testing, the canal model was applied to the Kennet and Avon Canal. The time series predicted by the model were compared to observed hydrological, solids, and chlorophyll-a (representing algae) data at multiple points in the canal. The model adequately predicted all of these constituents at the monitored locations.
The final task in the project required evaluation of six management scenarios proposed by the Environment Agency to address the water quality problem. The model suggests that filtration or other treatment of water in the canal near the confluence with the river is the best management option, as it will address both the elevated inorganic sediment and algae concentrations at the most critical point in the canal. Less desirable options include efforts that only target inorganic sediment, which could increase algal concentrations by increasing light availability; and diversion of surface flows from the canal, which could possibly damage the hydrologic balance of the canal while encouraging undesirable algal growth
Evaluation on the anatomic variations of the mandibular canal using cone beam computed tomography and panoramic radiography
No full textTCC (graduação) - Universidade Federal de Santa Catarina. Centro de Ciências da Saúde. Odontologia.Some procedures in dentistry, as anesthesia, dental implants placement and third molars extraction may vary the degree of difficulty and surgical complications, due to specific and individual anatomy of each patient. Detecting these variations is considerably relevant to the dentist, who is able to avoid and/or prevent intraoperative or postoperative complications. Focusing on the challenges in the mandible, this study aimed to assess the prevalence of anatomical variations of the mandibular canal, determining the most frequent, and comparing the results with those found in previous studies. 60 human cadavers’ jaws were submitted to radiographic and tomographic examinations, which were analyzed by a single calibrated observer. In the panoramic radiographs analysis the forward canal was the most common, registering 8,3%, while in the analysis of CT scans, the retromolar canal proved that it is more frequent, 35%. Cone-beam computed tomography proved to be more effective in the diagnosis of anatomical variations of mandibular canal and must be requested whenever exists suspicions of bifid mandibular canal in panoramic radiography.Alguns procedimentos na odontologia, como anestesias, instalação de implantes dentários e extrações de terceiros molares podem variar quanto ao grau de dificuldade e complicações cirúrgicas, devido à anatomia específica e individual de cada paciente. Detectar essas variações é de considerável relevância para o cirurgião dentista, sendo esse, capaz de evitar e/ou prevenir complicações transoperatórias ou pós-operatórias. Com enfoque nas alterações presentes na mandíbula, este estudo teve como objetivos avaliar a prevalência das variações anatômicas do canal mandibular, assim como comparar os resultados obtidos na análise de tomografias computadorizadas de feixe cônico, com os encontrados na análise de radiografias panorâmicas. Para tal, 60 mandíbulas de cadáveres humanos foram submetidas a exames radiográfico e tomográfico, os quais foram analisados por um único observador calibrado. Na análise das radiografias panorâmicas o canal duplicado em braço foi o mais comum, 8,3%, enquanto na análise das tomografias, o canal retromolar mostrou-se muito mais frequente, 35%. A tomografia computadorizada de feixe cônico mostrou-se muito mais eficaz no diagnóstico de variações anatômicas do canal mandibular e deve ser solicitada sempre que houver suspeita de duplicação do canal na radiografia panorâmica
