Website hosted by the American Ceramics Society with history of ceramics education, along with notable ceramic engineering educators. "In May 1894, two rooms in the basement of The Ohio State University?s College of Engineering were set aside to create a new department: Clay-Working and Ceramics. Founded with a $10,000 grant from the State of Ohio, the department was the first of its kind anywhere in the nation. The course of study was the idea and personal project of Edward Orton Jr., a young mining engineer. Orton had gathered his ceramic knowledge, piece by piece, from various jobs in coalmines, glass factories and steel plants. In 1893 he was the superintendent for a factory that made paving bricks. Orton?s factory, hit by an ?acute crisis,? closed, leaving him with some unexpected extra time. He used the opportunity to lobby for the passage of what some people dubbed the ?Mud Pie Bill? ? legislated funding to establish a school to train professionals in the ...

Many hoarding rodents use burrows not only for dwelling and protection from natural enemies, but also for food storage. However, little is known how burrows used by scatter-hoarding animals influence their foraging behaviors. In addition, handling time for a given food item has a fundamental impact on hoarding strategies of these hoarding animals: food items with longer handling time are more likely to be hoarded due to increasing predation risk because the animals spend more time outside their burrows if they consumed such food. By providing with two types of artificial burrows (aboveground vs. underground) and two types of food items (i.e. seeds) with contrasting handling times, we investigated how burrow condition and handling time co-influence hoarding strategies of a key scatter-hoard...

A brain weight deficit of about 70 mg was induced at doses of approximately 75-mGy and a deficit of 60 mg was induced at 100 mGy. This confirms the effects projected and observed by Wanner and Edwards. Although the data do not demonstrate a clear dose-response relationship between the 75-mGy and 100-mGy groups, the data are statistically consistent with a dose-response effect because of the overlapping confidence intervals. The lack of a statistically significant observation is most likely related to the small difference in doses and the limited numbers of animals examined. There are several factors that can influence the brain weight of guinea pig pups, such as caging and housing conditions, the sex of the animal, and litter size. These should be taken into account for accurate analysis. Dam weight did not appear to have a significant effect. The confirmation of a micrencephalic effect induced x rays at doses of 75-mGy during this late embryonic stage of ...

One of the hallmarks of linear coupling is the resonant exchange of oscillation amplitude between the horizontal and vertical planes when the difference between the unperturbed tunes is close to an integer. The standard derivation of this phenomenon (known as the difference resonance) can be found, for example, in the classic papers of Guignard [1, 2]. One starts with an uncoupled lattice and adds a linear perturbation that couples the two planes. The equations of motion are expressed in hamiltonian form. As the difference between the unperturbed tunes approaches an integer, one finds that the perturbing terms in the hamiltonian can be divided into terms that oscillate slowly and ones that oscillate rapidly. The rapidly oscillating terms are discarded or transformed to higher order with an appropriate canonical transformation. The resulting approximate hamiltonian gives equations of motion that clearly exhibit the exchange of oscillation amplitude between the two planes. If, instead of ...

Canada's offshore Atlantic petroleum industry is celebrating its tenth anniversary in 2001. This article chronicles the development of the industry discussing the many challenges and setbacks and the eventual triumphs that accompanied the industry's development over the years. Highlights discussed include shipping first oil from the Cohasset Field in July 1992; the financial crisis caused by the withdrawal of Gulf Oil from the Hibernia consortium in the same year; new funding and the beginning of the gravity-based structure construction at Bulls Arm in 1993; striking oil in the Hibernia Field in 1994; the start of exploration and development of the Terra Nova field by Petro-Canada in the same year, based on the floating production, storage and offloading (FPSO) system, which heralded a new era of offshore development in eastern Canada. Approval by the Nova Scotia government of the third and final phase of the Sable Offshore Energy Project followed in 1996 and the ...
