With the Intercollegiate Football Association disrupted by the resignation of Pennsylvania and Wesleyan, a new category of rules committee is created under the auspices of the University Athletic Club in New York City. The new rules committee comprises five older, more experienced men representing Harvard, Pennsylvania, Princeton, Yale, and the U.S. Navy with Paul Dashiell; all are graduates with responsible jobs. The IFA is left inactive, thus effectively ending student rule making. Rules are passed to limit momentum plays by allowing only three players to be in motion forward before the ball is snapped. A “linesman” is added as a third game official.

In response to a public perception of brutality and dishonest play in American football, President Theodore Roosevelt is persuaded to intervene, and he invites coaches and graduate leaders from the Big Three of Harvard, Princeton, and Yale (including Camp) to meet with him at the White House on October 9, 1905. After the meeting, Camp and the other two graduate leaders draft a pledge at Roosevelt’s request, promising responsive action by their schools. Violations of the pledge occur quickly in the 1905 Harvard-Pennsylvania and Harvard-Yale games, and Roosevelt requests visits from a representative of Pennsylvania and separately from Harvard. President Eliot writes Roosevelt, criticizing the Harvard-Yale game umpire, Navy professor Paul Dashiell, whereupon Roosevelt writes Dashiell and criticizes him; Dashiell replies with a strong defense that persuades Roosevelt. Roosevelt continues to correspond with Camp in a complimentary manner.

A nuclear power plant is undergoing an emergency shutdown procedure known as a “scram” when there is an unusual vibration and the coolant level drops precipitously. Subsequent investigation by a shift supervisor reveals that X-rays of welds have been falsified and other problems exist with the plant that could potentially cause a core meltdown that would breach the containment building and cause an explosion. However, the results of the investigation are squelched and the plant is brought up to full power. The shift supervisor takes the control room hostage but is then shot by a SWAT team as the reactor is scrammed. A meltdown does not actually occur. No, this did not really happen, but these events—portrayed in the movie The China Syndrome —evoked a scenario in which a nuclear core meltdown could melt its way to China and contaminate an area the size of Pennsylvania. It also exposed a nuclear power culture that covered up safety issues rather than fixing them. It made for a compelling anti-nuclear story that scared a lot of people. And then a real core meltdown happened, 12 days later. The worst commercial nuclear power reactor accident in US history began on Three Mile Island, an island in the Susquehanna River three miles downstream from Middletown, Pennsylvania (hence its name). Two nuclear reactors were built on this island, but one of them (TMI-1) was shut down for refueling while the other one (TMI-2) was running at full power, rated at 786 MWe. At 4:00 a.m., what should have been a minor glitch in the secondary cooling loop began a series of events that led to a true core meltdown, but no China syndrome occurred and there was little contamination outside the plant. Nevertheless, it caused panic, roused anti-nuclear sentiment in the country, and shut down the construction of new nuclear power plants in the United States for decades. The nuclear reactors at Three Mile Island were pressurized water reactors (PWR), the type of reactor that Admiral Rickover had designed for power plants in US Navy nuclear submarines.

The General Electric LM2500 Marine Gas Turbine, currently used by the United States Navy as main propulsion on various classes of ships, lends itself very easily to a procedure known as photoborescopy. Photoborescopy is that process where discrete, color photographs are taken of various internal parts of the engine. Borescoping in itself is not new, but maximizing the borescopes capabilities is a program that the U.S. Navy continuously is developing at the Naval Ship Systems Engineering Station (NAVSSES) in Philadelphia, Pennsylvania. This paper will describe the photoborescopy technique used

The U.S. Navy operates Rolls Royce 501-K34 powered Gas Turbine Generators (GTGs) on DDG 51 Class destroyers. The design of these GTGs has evolved significantly over the course of the shipbuilding program. One significant change is that GTGs on DDG 51 to 90 are rated to provide 2,500 KW while those on DDG 91 and follow are rated at 3,000 KW. The 3,000 KW rating has been accepted by the Navy and demonstrated on several new GTGs during qualification testing. However, test results indicate that one area where very little performance margin exists is full load transient response. This paper discuss

The research question at the center of this paper was initiated in response to my participation in a larger Department of Energy funded project awarded to the Greater Philadelphia Innovation Cluster for Energy Efficient Buildings (GPIC). My particular research initiatives within GPIC are focused on developing a roadmap of use by architects, engineers, builders and building owners for the successful implementation and market adoption of rigorous Integrated Design Practices in the energy efficient retrofit of buildings in a 10 county region of the Mid Atlantic region, that includes the city of P
